Let's begin with the OnePlus 3. The phone comes with a curved metal back which is easier to hold and it's rear features prominent antenna lines, LED flash and a single rear camera. Basically, the back of the phone is less cluttered than most phones and unlike the HTC 10, the phone's fingerprint sensor is embedded in the home button on the face of OnePlus 3. OnePlus 3 also features an Alert Slider on its side which lets you toggle through notifications, priority notifications and silent mode. You'll also find a power button as well as volume controls.
Just like the OnePlus 3, Vodafone Smart Platinum 7 fares well in the looks department. A mere look at it will make you feel as if you're staring at a phone that costs upwards of £600. The phone gives the Samsung Galaxy S7 a run for its money and features three physical buttons on the sides, out of which one can be used to quick launch any app of your choice. The back of the phone is dragontail glass and there is a dark texturing underneath it making it look very expensive. The fingerprint sensor rests on the back of the phone but isn't as quick to react as the one in the OnePlus 3.
Even though Honor 8 features twin rear cameras on its back, the cameras take as little space as possible and along with the fingerprint sensor below them, leave a lot of space to place your fingers while holding the device. The designers have saved some valuable space in the handset by turning one of the SIM slots into a MicroSD slot and apart from Aluminium sides, the rest of its body is entirely covered in glass which gives it a sleek and shiny look. There's no home button at the front and the top of the phone looks a lot like an iPhone.
Winner: OnePlus 3 for fingerprint sensor and Alert Slider; Honor 8 for no camera bump.
Choosing a smartphone display depends on whether you like large ones for your multimedia needs or decent 5-inch ones which you can use one-handed. OnePlus 3 comes with a 5.5-inch Full HD AMOLED display which is crisp and bright but new users may have some trouble with the oversaturated colours. The Vodafone Smart Platinum 7 features a similar-sized display but its resolution is a much better Quad HD one and the phone also comes with Miracast 1080p HD support which makes video streaming a very good experience. The Snapdragon 652 octa-core processor in the phone also supports 4K Ultra HD capture and playback, along with 2K display support.
The Honor 8 is smaller than the other two and features a 5.2-inch Full HD display which is similar to the one in OnePlus 3 but not as crisp as the one in Smart Platinum 7. However, it is also true that Full HD resolutions are enough for most people to enjoy multimedia seamlessly without severely impacting battery life.
Winner: Vodafone Smart Platinum 7
OnePlus surprised the world when they announced a 6GB RAM for the OnePlus 3 which costs a lot less than other premium smartphones. Together with the latest Snapdragon 820 octa-core processor, the RAM offer a flawless and smooth experience to OnePlus 3 users and if you are a gamer, you will be very pleased with your purchase.
Vodafone Smart Platinum 7 is comparatively under-powered, featuring a Snapdragon 652 octa-core processor and 3GB of RAM and compared to OnePlus 3's AnTuTu benchmark score of 143371, it scored just 75327. However, it is still faster than LG G4 and Nexus 6 which are significantly pricier. Jumping between apps is effortless and Games like Ninja Slice, Sonic and Solitaire didn't slow the phone down at all.
Honor 8 features an octa-core Kirin 950 processor along with 3GB and 4GB RAM options which are great for a phone which is not very large. The processor is the same as in the Huawei P9 and Huawei Mate S and those phones haven't disappointed us in the least.
Winner: OnePlus 3
Despite the emergence of cloud storage services, an overwhelming number of smartphone users still rely on basic storage capacities of their devices as well as additional storage options which are easy to access. OnePlus 3 comes with an impressive 64GB of on-board storage but lacks a MicroSD slot which means you'll have to rely on cloud services if you want to store some more data which you'll need sooner or later.
Vodafone's Smart Platinum 7 features 32GB of storage out of which you'll be able to access only around 25GB but the phone's MicroSD slot can take in as much as 200GB of additional storage. Honor 8, on the other hand, will be available in both 32GB and 64GB storage variants and one of its SIM slots works like a MicroSD slot as well to let you choose if you'd prefer to use another number or just add more data in your phone.
Winner: Honor 8
A Quad HD display, a large one at that, consumes more power than a Full HD one and as such, phones with Quad HD displays need to field powerful batteries so that you do not have to compromise on a phone's longevity by using it regularly. Vodafone's Smart Platinum 7's 3,000 mAh battery seems powerful enough for a long lasting experience but the Quad HD display may hamper an all-day usage. However, thanks to Qualcomm's Quick Charge 3.0 tech, you will be able to juice it up in double quick time as well. During our review, the battery dropped a mere 4% during 20 minutes of HD quality YouTube streaming over 4G which is a great feat.
OnePlus 3 also features a 3,000 mAh battery but enjoys the comfort of a Full HD display than a power-consuming Quad HD one. It lasted two days under regular usage on a single charge during our review and the Oxygen OS has several baked-in customisation options that help with conserving battery power. At the same time, the DASH charge feature lets you charge the phone battery faster than any other phone.
Honor 8 also fields- no points for guessing- a 3,000 mAh battery and features built-in Huawei’s proprietary power saving technologies as well as fast-charge technology which can recharge the battery by up to 50% in about 30 minutes. Even though we haven't been able to review it, we believe the smaller and less-power-consuming display along with the power-efficient Kirin 950 processor will make the battery last longer than the other two under regular usage.
Winner: Honor 8 and OnePlus 3
OnePlus 3 features a 16-MP primary camera with Optical Image Stabilisation, EIS and a manual mode that supports RAW images. Even though it isn't as good as the one in Galaxy S7, it will offers a decent performance given the phone's price tag. The front-facing camera is an 8-MP one and it has a 'Smile Capture' function as well as the beauty slider so you never have any nightmare selfies again.
Vodafone Smart Platinum 7 also comes with a 16-MP primary camera which lacks Optical Image Stabilisation but features an inbuilt image stabiliser which isn't too bad. In terms of options, the camera will let you take pictures in resolutions ranging from a lowly 4-MP to up to 16-MP with HDR. You will also be able to record videos in UltraHD, QHD, Full HD, just HD and VGA resolutions. The front camera is an 8-MP one featuring dual tone LED flash.
Honor 8 borrows its camera setup from the Huawei P9 and this makes it by far the undisputable champion among the three phones. The 12-MP dual rear cameras bring in in clarity, detail and crispness to images, especially low light ones. Each of the dual-cameras, namely the RGB and the monochrome ones, specialize in bright colour and black and white imaging respectively. When both cameras work together, the resulting images are a mixture of vivid colours and lovely shades, saving you the effort of searching for photo-editing apps to beautify your raw pictures. You can even takes pictures using each of these cameras as standalones and choose between Standard, Vivid Colours and Smooth Colours modes. The front camera is a wide-angle 8-MP one which is fine-tuned to work in low light conditions as well.
Even though the three phones are very much similar in terms of looks, overall performance and features, Honor 8 turns out to be the one which we can term as an all-rounder. The phone features an advanced processor, sufficient storage, brilliant cameras and a powerful battery given its size. OnePlus 3 can give it a close fight in terms of speed and looks but it has been plagued by several issues since launch including users unable to play HD videos on YouTube, bugs in the front camera, issues with the functioning of Android Pay and the Doze feature killing notifications. As such, OnePlus will need some time to fix these issues and make the OnePlus 3 perfect in the long run. Until then, we'll go with the Honor 8.
