Themost headline-grabbing smartphone launch from Asus at CES 2015 may be the optical zoom-sporting ZenFone Zoom, but the ZenFone 2 is also very worthy of attention thanks to a solid feature set
TechRadar Verdict Asus Zenfone 2 is a cheap way to upgrade to an Android Lollipop phone, housing a display and solid specs to boot. But a dull screen, plastic design and poor camera hold this handset back. Pros +Inexpensive Android phone+Spacious display+Lots of RAM+Two SIM card slots+Full of customization options Cons -Cheap look and feel-Dim screen-Poor camera quality-Weak power button Why you can trust TechRadar We spend hours testing every product or service we review, so you can be sure you’re buying the best. Find out more about how we test. The Asus Zenfone 2 fills an interesting niche as an Android phone full of deep customizations, yet one that sells for half the price of similarly sized Android tinkerers who want to invest a lot of time into customizing their phone also have to pay full price for a flagship. But the Zenfone 2 turns that concept on its meditating $300 about £210, AU$408 unlocked and now available in the US, it's a bargain for a display that's as big as a the LG G4 and iPhone 6 Plus, and specs that include a speedy Intel processor and 4GB of an even cheaper $200 about £139, AU$272 model with a slower Intel chip and just 2GB of RAM, but the 4GB version is the one that's going to last you some time – if it holds Zenfone 2 makes its compromises to hit that price point is in its build quality and camera. It's easy to spot the flaws of its cheaper plastic construction and poor 13-megapixel said, the Zenfone 2 remains one of the most inexpensive ways to upgrade to Android Lollipop with enough processing power leftover, so long as you don't care about style or 2 is true to its unintentional theme of finding internal strength and beauty because, on the outside, this isn't a very pretty or strong Zenfone 2 review It feels more cheaply made than it looks. This is thanks to the artfully deceptive, brushed metal design on the back cover and its display made with Gorilla Glass 3 and an anti-glare coating .But holding the phablet in my stretched out hand, I could tell the difference between it and the glass-backed Samsung Galaxy S6 and aluminum-backed iPhone 6 Plus right could also see the difference in quality as my stretched out hand accidentally dropped the phone, and its top-right corner met pavement. Cracks spread across the screen's surface and a frown stretched across my unintentional drop test was a tumble at 32 inches 81cm, rather than a direct drop, from my pocket. The phone's bulkier-than-normal dimensions didn't fit in my jeans as well as I had Samsung and HTC upgraded their flagship phones to Gorilla Glass 4, Asus stuck with the previous generation's less durable material. LG G4 kept Gorilla Glass 3 too, but at least it features a slight curve that might have saved this phone from its now unsightly the plastic body and cheaper glass construction, the Zenfone 2's dimensions and weight are less svelte, as expected given its curved back gives it a thickness of By comparison, the Galaxy S6 is the HTC One M9 is and the LG G4's thickest point is rest of the measurements are actually competitive. It's in length with a width. But, at 170g, it weighs slightly more than everything but the iPhone 6 2 also cheaps out on the power button. It sits at the top of the phone, in an odd center location, and has little tactical feedback, almost as if it's broken. Luckily, the phone's software makes use of the handy double-tap-to-wake screen feature introduced in the LG the power button is annoyingly squishy, the volume buttons have the necessary clicky feedback, taking cues from LG with their location on the capacitive buttons for back, home and recent line the bottom of the display, but are neither on-screen buttons, like on some Androids; nor do they light up, like on Samsung devices. This makes it difficult if you're moving from a Samsung phone where the back and recent buttons are swapped, as you may have trouble getting used to this order in the a single loud-sounding speaker, but it stretches across the back of the phone, which means calls on speakerphone and music point in the wrong direction. Costlier phones, like the Galaxy S6, have moved the speaker to the bottom of the phone. Better yet, the HTC One M9 has stereo speakers on the Asus Zenfone 2 can compete on size, especially for the price. Its large display, which is slowly becoming the norm among Android phones, feels quite from typing out messages to getting work done on the spacious, LED-backlit LCD is a little bit easier, and this phablet has enterprise-ready specs to back up that don't expect a super-rich screen for fun multimedia. Its diagonal measurement matches the LG G4, but its resolution of 1,920 x 1,080 cannot compare to a quad HD importantly, while its the same resolution as the 1080p iPhone 6 Plus, the brightness literally pales in comparison to Apple's Retina or Samsung's Super AMOLED appears to be half as bright, even at full brightness That becomes a real problem when in sunlight. Taking a photo at the sun-drenched beach is nearly impossible when you can't use the display as a viewfinder. For better or worse, the Zenfone 2 isn't a great camera phone, so the point is kind of moot do like how, even when selecting the "auto" ambient light mode, the brightness can be adjusted ever so slightly. But overall, the screen looks half as bright as it should be. Current page Introduction, design and display Next Page Specs, performance and software Most Popular

Diretamente, comparamos o modelo da ASUS com os seguintes celulares Samsung Galaxy S6, Motorola Moto X Play, LG G4, HTC One M9 e Sony Xperia Z3+.Análise smartphone ASUS Zenfone 2 [vídeo]Análise smartphone ASUS Zenfone 2 [vídeo]Análise smartphone ASUS Zenfone 2 [vídeo]DesempenhoO Zenfone 2 é poderoso, isso é inegável. Seu conjunto de hardware reúne um processador de quatro núcleos Intel Atom Z3580 de 2,3 GHz com 4 GB de RAM. Oficialmente, o Zenfone 2 é o primeiro modelo a contar com tanta memória disponível. Por conta disso, o usuário pode ficar tranquilo não há gargalos ou nossos testes de benchmark, o modelo se mostrou eficiente, batendo o Moto X Play em vários testes. Aliás, o Moto X Play é o aparelho que pode ser apontado como o concorrente direto do Zenfone 2, uma vez que o desempenho de ambos, bem como a proposta de preço, é bastante dos 4 GB de RAM serem um bom diferencial na maioria dos momentos você verá uma boa quantidade de memória dos 4 GB de RAM serem um bom diferencial – a quantidade de memória dá e sobra para todas as funções que você precisar executar –, na maioria dos momentos você verá uma boa quantidade de RAM ociosa. Na prática, se o aparelho tivesse 3 GB provavelmente o desempenho fosse o mesmo, ainda que em alguns poucos momentos pudesse haver algum transição entre aplicativos é rápida e eficiente e o software disponibiliza ainda funções para que você limpar processos em execução com agilidade. Abrir vários apps e deixa-los em segundo plano não vai ser mais um problema. Contudo, fica o alerta é possível fazer o mesmo com menos memória – ao menos na atual quem gosta de interfaces puras, o Zenfone 2 não é um boa escolha. A ASUS optou por colocar em seus produtos a Zen UI, uma interface que prima pelas possibilidades de modificação que o usuário tem à sua disposição.

Outro atrativo é a tecnologia ZenMotion, que permite a utilização de gestos para interação. Escrevendo a letra “C” na tela, por exemplo, a câmera é aberta; “W” abre o navegador; entre outros comandos.“C” – abre a câmera“W” – abre o navegador“O” – abre a agenda“E” – abre o email“Z” – abre o ASUS Booster“V” – abre o discadorPor fim, o modelo conta com modos de acesso “fácil” ou para “crianças”, que torna a interface simplificada. Em nossos testes, chamou a atenção o fato de que a ASUS embarcou muitos aplicativos próprios no aparelho, boa parte deles bastante úteis, mas ainda assim o número parece disso, há espaço de armazenamento de sobra e esse não deve ser um problema. Entretanto, como mencionamos anteriormente, certamente aqueles que preferem um Android um pouco mais “limpo” não vão gostar do as telas de LCD contam com 4 camadas em sua composição. O aparelho da ASUS conta com uma tecnologia chamada TruVivid, que permite eliminar duas delas. O resultado disso é um índice menor de reflexos, respostas mais rápidas ao toque e níveis mais alto de brilho e fato, em nossos testes, a tela do Zenfone 2 se saiu razoavelmente bem em todos os quesitos avaliados. Contra a luz intensa ou sob a luz do sol, a visibilidade é regular, sem reflexos excessivos. O deslizar dos dedos sobre a tela é suave, o que mostra que o display é igualmente competente ao de outros tops de linha, mas apesar da camada anti-digitais que reveste o display, notamos que as marcas de impressões digitais permanecem no aparelho da ASUS conta com uma tecnologia chamada TruVivid, que permite eliminar duas das quatro camadas tradicionais do 5,5 polegadas de tamanho, merece destaque ainda o fato de que a ASUS optou por bordas mais finas em seu dispositivo. Os méritos do design se refletem um produto que em seu corpo não aparenta ser muito maior do que um dispositivo com 5 polegadas, por na parte frontal, vale a menção de que os botões capacitivos não são iluminados, o que pode incomodar um pouco na hora de manuseá-lo no escuro. Trata-se de uma opção da fabricante e que pode agradar ou desagradar os consumidores. Sinceramente, durante minha utilização, não considerei isso um ASUS deu uma atenção especial às câmeras do seu mais novo smartphone. A câmera traseira, com 13 megapixels de resolução, conta com a tecnologia PixelMaster que reconhece o ambiente e ajusta os modos de captura a uma das 16 opções linhas gerais, a câmera do aparelho é razoável e o usuário consegue boas fotos com ela. O grande destaque fica por conta do uso dela em situações com baixa luminosidade – e é onde entra em ação a PixelMaster. Ela combina 4 pixels em um único “superpixel” e o resultado são imagens com 4 vezes mais sensibilidade à luz e contraste. O nível de ruídos também é drasticamente quem gosta de trabalhar um pouco mais as suas imagens, há opção ainda de captura a partir de um modo manual.

O software permite ainda que você tire “Selfie Panorama”, permitindo ampliar o campo de visão para até 140 graus. Há um modo de “embelezamento em tempo real”, similar ao do Redmi 2, e softwares para edição de imagem a capacidade de bateria do ASUS Zenfone 2 está entre as maiores do mercado. Os mAh de capacidade colocam o aparelho à frente de modelos como Apple iPhone 6 Plus, Samsung Galaxy S6 ou HTC One M9, por exemplo, e lado a lado com o LG G4. Entretanto, na prática isso não significa um desempenho acima da nossos testes, o desempenho de bateria ficou dentro dos parâmetros esperados, mas o aparelho não pode ser considerado um destaque nesse quesito. Usando o celular de forma intensa WiFi e 3G ativos, rodando jogos e vídeos de forma alternada continuamente foram necessárias pouco mais de seis horas para drenar a carga por vale lembrar que ele conta com modos específicos para economia de energia. É o caso do “Modo de economia inteligente”, que permite personalizar as suas próprias configurações de economia de energia, e o “Modo ultra-econômico”, que maximiza a vida da bateria e desconecta a rede quando o dispositivo é suspenso. Em ambos os casos, pode haver ganhos significativos de durabilidade da carga, chegando a até 20% do aqueles que têm pressa, o modelo é compatível ainda com a tecnologia BoostMaster, que permite a recarga rápida do aparelho. De acordo com a ASUS, com ele ativado é possível levar a carga de 0% a 60% em apenas 39 minutos. Em nossos testes, demorou um pouco mais do que isso – 44 minutos -, mas inegavelmente o índice obtido é bastante pontos positivos e negativos significativos que devem ser observados na qualidade de áudio do Zenfone 2. Vamos começar pelas boas notícias. A empresa decidiu incluir um aplicativo chamado “Assistente de Áudio” que, de fato, tem um bom impacto sobre a qualidade sonora conta com configurações prévias para estilos musicais, filmes, gravações, conversas via telefone ou jogos. Ou seja, na prática você pode adaptar o seu dispositivo à necessidade em questão, uma característica que muitas vezes é deixada de lado pelas Zenfone 2 conta com configurações prévias para estilos musicais, filmes, gravações, conversas via telefone ou aspecto negativo é que, embora o som dos speakers seja alto, por vezes ele soa um tanto quanto estridente e embargado. Essa característica não chega a ser um problema, mas pode incomodar aqueles que valorizam esse recurso. O microfone para gravações é apenas fones de ouvido que acompanham o produto são do tipo intra-auricular e têm qualidade mediana. Eles são suficientes para você ouvir suas músicas sem se incomodar muito, mas aqueles que valorizam todos os aspectos de áudio de boa sonoridade – e essa sempre foi uma característica positiva de outros produtos da ASUS – certamente vão se decepcionar um pouco a pena?A ASUS pode ser considerada uma das mais gratas surpresas do mercado de smartphones. Com o Zenfone 5 ela conseguiu aliar um produto de boa qualidade a um custo acessível e compatível com a sua proposta. O Zenfone 2 representa uma mudança de categoria, já que agora a empresa planeja brigar também pelos tops de comparativo direto, é possível apontar o Zenfone 2 como o rival direto do Motorola Moto X Play. Ele ganha em alguns quesitos, como câmera e desempenho, e serve como opção para quem gosta de interfaces com mais funções e recursos. O aparelho da Motorola, por outro lado, tem bom desempenho de bateria, é resistente a água e chega às lojas por um preço Zenfone 2 se mostra equilibrado e chama a atenção pelos bons resultados em fotos noturnas e, principalmente, pelo desempenho, graças aos 4 GB de RAM. Com preço competitivo dentro de sua proposta, o modelo sem dúvida deve figurar nas listas de mais vendidos de 2015. Bom para o consumidor, numa prova de que ele não precisa de forma alguma gastar mais do que R$ 2 mil em um celular hoje em os preços do ASUS Zenfone 2ASUS Zenfone 2 16 GBASUS Zenfone 2 32 GB ASUSPhilippines just introduced its Zenfone 2 Deluxe Special Edition which builds on top of the Deluxe that we saw earlier this year. The limited edition handset comes with slightly tweaked processor, 256GB of total storage, and a few other special goodies that go along with the package. Since this is just a facelift of the If the 4GB version of the Asus Zenfone 2 were $100 cheaper, it would be near the top of our recommended phones list; however, its $299 and S$499 converting directly to about £245 and AU$475 price makes it a tough sell in a world of capable sub-$200 Good The Asus ZenFone 2 delivers smooth performance, an impressive low-light camera, and has a clean feature-rich UI. The screen is sharp and bright. The Bad The phone has a cheap bulky feel and an unintuitive button layout. Its non-swappable battery delivers only decent life. The price is too high for its above-average capabilities. The Bottom Line The Asus ZenFone 2 is too expensive for its above-average ability, but if the price agrees with you, the smooth performance and splendid low-light camera won't disappoint. There is a cheaper 2GB version of the phone retailing for $199 converting to £127 and AU$249; however, since we've as of yet spent no time with the 2GB version, we can't yet say how it performs compared to the its 4GB sibling. Both versions of the phone are available now unlocked at Amazon, Newegg and Groupon in the US. The 4GB ZenFone 2 is somewhere in-between budget and flagship, but unfortunately lacks the top-of-the-line performance and features we'd expect from a high-end handset. That said, it's capable in its own right, delivering silky smooth performance thanks to its combination Intel Atom CPU and 4GB of RAM. And while its 13-megapixel rear camera takes decent shots, its low-light performance handily beats that of the Samsung Galaxy S6 and Apple iPhone 6. It has a sharp vibrant screen, but the plastic build unfortunately feels cheap and bulky. Its Zen UI is clean, aesthetically pleasing and packed with useful features, but can at times isn't all that intuitive to navigate thanks to the changes Asus made to its Android interface. Those looking to spend less, should check out the Samsung Galaxy Grand Prime. It has longer battery life, decent cameras and costs less than $200. The Galaxy S6 and S6 Edge are the current highest of high-end Android, but tip the scales at $600 unless you're willing to commit to a 2-year lineup What Asus calls the ZenFone 2 is actually two different models with five different variants, three with screens and two with 5-inch displays. Each model has a different price point, RAM, and built-in storage capacity, but the whole range is marketed under the same name. Asus is likely trying to avoid last year's problems with its first ZenFone line - the phones were marketed as ZenFone 4, 5 and 6, which was probably even more confusing for consumers since it sounded like subsequent generations of phones were being sold at the same time. To lesson the confusion, we've created a table that lists the details of each of the new ZenFone 2 models. Our review unit is the version with 4GB RAM and 32GB of onboard storage that retails for S$429 and $299 in the US around £210 or AU$410.

It's just slightly shorter than the iPhone 6 Plus, but the Apple phone is thinner at The thickness means the ZenFone does make its presence felt in the pocket, and with more smartphones taking the slim approach, the ZenFone 2's size and weight of 170g 6 ounces doesn't do it any favors. The phone's rear sports a brushed metal look, but it's actually plastic. Aloysius Low/CNET Clad in plastic like the first ZenFone, the ZenFone 2 opts for a brushed metal look, unlike the soft-touch feel used previously. While it looks metallic, it still feels slightly plasticky I prefer the original, though I can see why Asus chose to go with the metallic style and it looks a lot more premium at first glance. That said, the rear cover is replaceable and comes in a variety of colors - the standard black and white, and a more colorful range of red, gold, grey. Asus will also sell a special range of "Illusion" covers that come in a pretty crystal pattern. Viewed head on, the ZenFone 2 resembles the first ZenFone, from the Asus logo near the top speakers, to the concentric circle pattern below the display. The touch-sensitive buttons are located just above that. In a way, I'm glad that Asus has stuck with the familiar, but I do wish the phone used software buttons instead - this would probably have helped cut down on the phone's size. The ZenFone 2 resembles the original ZenFone and uses touch-sensitive menu keys as well. Aloysius Low/CNET Right at the top is where you'll find the awkwardly placed power button, and it's an odd choice, since Asus has chosen to borrow LG's great idea of moving the volume buttons to the rear of the phone. The button is quite a stretch to reach it if you're holding the phone with one hand. Asus should have just placed the power button on the rear, together with the volume controls. The power button is placed at the top next to the audio jack. It's quite a strange position since you'll have to stretch your fingers to reach it. Aloysius Low/CNET The removable rear cover gives you access to the dual-SIM and microSD slots. The 3,000mAh battery is non removable, so you won't be able to swap it out for a fresh one. Unlike some of the other dual-SIM phones which come with dual 4G capabilities, the ZenFone 2 only has one active 4G SIM, with the other SIM limited to 2G and software quad-core Intel Atom Z3580 32GB of storage 4GB of RAM Expandable storage 3,000mAh non-removable battery Powered by Intel's Atom Quad Core Z3580 processor clocked at this model of the ZenFone 2 comes packing a whopping 4GB of RAM. Most smartphones, including high-end flagships, come loaded with 3GB at most. Asus claims having 4GB of RAM helps the ZenFone 2 multitask more on this later, as multiple apps and can remain on standby in the background without needing to be offloaded to memory and reloaded. Our review model came with 32GB of onboard storage, and if that somehow isn't enough for your needs, there's a microSD slot to add even more space. There's a 13-megapixel camera located at the rear, and a 5-megapixel shooter on the front. The rear 13-megapixel camera comes paired with dual-LED flash. Aloysius Low/CNET Inside you'll find the dual-SIM and microSD card slots. The battery is non-removable. Do also note the phone only supports 4G on one SIM slot, the other SIM slot is stuck on 2G. Aloysius Low/CNET The display comes with a full-HD resolution of 1,920x1,080-pixels, protected by Corning's Gorilla Glass 3. Sure, it's not a QHD display found on some flagships, but only a few users would be able to tell the difference between 2K resolution and full-HD. Also, the screen has wide viewing angles and colors are bright and vibrant. Even under direct sunlight, the integrity of the screen holds up well. Asus has polished its Zen UI further, but it's a custom skin layered over Google's Android Lollipop. Since its introduction last year, Zen UI features a flat minimalist look. Features from the earlier iteration return, such as Do It Later, a handy reminder app that helps you keep track of SMSes to reply to, articles to read and missed calls to return. Zen UI packs plenty of new features, including the ability to theme the phone's look and icons. Screenshot by Aloysius Low/CNET Zen UI also offers a lot of customization options that will boggle your mind with choice. Screenshot by Aloysius Low/CNET Like Chinese smartphone maker Xiaomi's MIUI, Zen UI also features the ability to change your phone's theme, so if you don't like the current look, you can swap it to something you'd prefer. Another fun thing you can do is change the color of the fonts on your phone - this works if you prefer a lighter background wallpaper - you can then use a darker color for your fonts so that it shows up. New features include drawing on the screen when the phone is locked to activate features called ZenMotion and a guest mode for when you need to pass the phone over to a friend to use though you'll need to make sure you password lock your phone first so they can't switch it back and access your data!. The Auto-Start Manager app lets you select which apps to load into memory when you reboot your phone. You can also change the font colors on the home screens. Screenshot by Aloysius Low/CNET There are also a bunch of hidden tweaks, such as the ability to double tap the Home button to turn on one-handed mode, and power users will appreciate the fact you can also set which apps will autorun when the phone boots to help it start faster. Asus however seems to have forgotten about some important bits of the UI design. Annoyingly, there's no 'clear' button for notifications on the lock screen, something other Lollipop phones have. It's still a pretty good UI, and Asus has done a great job of adding its own touch to Android. The biggest issue I have is that the UI is packed with so many features you'll have to take your time to learn them all, and it feels like the Samsung kitchen-sink approach all over again where there's just way too many features that never really get discovered or rear camera 1,080p HD video 5-megapixel front camera Low-light mode Asus put plenty of work into the ZenFones 2's 13-megapixel f/ rear camera, resulting in impressive low-light performance. Called PixelMaster, the phone's low-light mode imaging tweaks to deliver well-lit shots even when there's barely any light. There are however a few caveats with low-light mode. First, shots taken in this mode are hypersensitive to movement, so you'll need to hold the phone really steady or use a tripod to avoid blurry shots. Also, the resulting image is only 3 megapixels in size, since it uses pixel binning, which combines four pixels into one. This "larger" pixel is able to read more light data, leading to a better low-light shot. The resulting picture is surprisingly bright compared with other phones. Now, I can testify that this works - the picture is surprisingly bright compared with say, high-end phones such as the iPhone 6 and the Samsung Galaxy S6 Edge. Do take note this isn't a new feature, it was already present on the first ZenFone, but it seems to have been improved upon. The front 5-megapixel camera includes a beautification mode, which helps smooth out wrinkles and touches up blemishes on your skin. Not something we haven't seen before in other phones, but still useful. The ZenFone 2 is capable of shooting full-HD video, and like all smartphones, videos are best shot in bright light for the best performance. During my test, I did find I'd have to tap the screen to refocus, since the autofocus didn't kick in when you transition to a background to a foreground shot. Check out the shots below to find out how the camera performed in my tests. Enlarge Image Outdoor test shot without HDR. Colors seem a little too saturated here, but HDR in the next picture cranks it up a lot.

Aloysius Low/CNET Enlarge Image The ZenFone 2 seems to slightly overexpose indoor shots, I noticed this in the other pictures I took. The camera seems to perform better under incandescent lighting. Aloysius Low/CNET Enlarge Image Low-light mode is where the phone really shines, and you'll see in the next picture why I feel the ZenFone 2 is really better for lowlight shots in this mode. Aloysius Low/CNET It's not that the shots are bad, but the low-light mode of Asus is a lot brighter though at the cost of picture size. That said, if you don't use lowlight mode, the image taken with the ZenFone 2 isn't quite as good as the Galaxy S6 Edge or the iPhone 6 Plus. Aloysius Low/CNETPerformance and battery life Intel's known for its desktop and notebook processors, and its efforts to gain a foothold in the handset business have been decent so far. Earlier versions of its mobile processors weren't as power efficient as ARM devices. But Intel has worked on improving the performance and efficiency with the newer Intel Atom devices. While most of them are better for tablets, the chip maker has spent time on getting its processors ready for mobile. Given that there aren't many Intel-powered phones in the market right now, it's hard to find a direct comparison with another phone. But going by the benchmark results, the quad-core Intel Atom Z3580 processor inside the ZenFone 2 seems capable of going up against the midrange Qualcomm chipsets, such as the Snapdragon 615 found in the Xiaomi Mi 4i. The benchmark results seem to indicate performance around the same levels. Now, of course, benchmark results don't tell the whole performance story, but I found the ZenFone 2 to be pretty smooth during day-to-day use. The phone booted up in 44 seconds, and the camera loaded instantly. On games such as Asphalt 8, a hardware-taxing 3D driving game, the phone ran smoothly with nary a hiccup and loading times were zippy. Based on the numbers below, it would seem that the Intel Atom CPU is achieves similar performance to a midrange Qualcomm chip, such as the Snapdragon 615 on the Xiaomi Mi 4i. The numbers are pretty close on Quadrant - 24,606 to the ZenFone 2's 22,991, but the ZenFone 2 loses out in the Geekbench 3 test with a score of 2,926 to the Mi 4i's 2,566. On 3DMark the phone does well, but isn't exactly setting the world afire. The ZenFone 2 delivers smooth performance when opening apps and navigating the interface, and while we didn't experience any problems when playing games, don't expect performance to reach the same levels of top flagships like the Galaxy S6 or LG G4. It seems Intel may have finally gotten its Intel Atom chips right for phones, and perhaps we will see more devices being powered by its processors - this could open up the market further, as devices no longer need to be limited to ARM chips. However, let's hope a GPU upgrade is in the works for future versions of the chip.

That's about four hours less than the Mi 4i which has a slightly larger 3,120mAh battery which lasted 13 hours and 18 minutes, it's not really as good. Perhaps video playback isn't really the phone's strong suit, as I found that anecdotally, the phone usually lasts a whole day for me, which is good enough, but still not great. Call quality During my time with the ZenFone 2, I had no issues with making calls. Voices were clear and crisp and the other party could hear me clearly as well. The phone's speakers, however, can be a little soft, so you may miss calls or notifications if you're in a noisy place. 4G LTE speeds seemed pretty decent - the phone was tested in Singapore on SingTel's 4G network, on the Ookla Speedtest app, the ZenFone 2 managed to pull download speeds on its fastest run.

Screenshot by Aloysius Low/CNETConclusion While the ZenFone 2 won't dazzle you with a beautiful design or premium materials, the hardware inside is far from lacking. The Intel-powered phone manages to hold its own, but it's still too early to tell if the ZenFone 2 will start a wave of smartphones using Intel chips. Given its relatively high $299 price without a contract for the top end model, Asus may struggle to gain ground against the much cheaper lower-end handsets such as the Mi 4i , which will be sold in the same markets in Asia, and the $200 Samsung Galaxy Grand Prime , available in the US. And if you factor in the $260 Mi Note though this is still limited to China, the ZenFone 2 may seem a little overpriced. There is still the $199 option, but it includes only 16GB of storage and 2GB of RAM compared to the $299 version's 64GB of storage and 4GB of RAM, and since we've only used the 4GB version, we can only speak to its merits. But interestingly, the $299 price for the 4GB does put it in an interesting position, since the focus recently has been on either great low-value phones and high-end handsets. The ZenFone 2 could still be attractive for those who want near high-end performance without being tied to a contract. Aloysius Low/CNET Asushas redesigned its current phone Zenfone 2 and marketing it with newer improvements. Zenfone 2 Deluxe is one such attempt. The details of the device are - Design Design continues to be similar to Zenfone 2. The buttons are positioned on the back of the device. The back of the phone has really good design changeover.
