Spec comparison: OnePlus 3 vs Sony Xperia X vs Vodafone Smart Platinum 7

OnePlus launched OnePlus 3 yesterday and immediately put up the £309 smartphone on sale to capitalize on the hype around its latest flagship. If you're thinking about buying the phone at a low price point, you should also take a look at Vodafone's Smart Platinum 7 phone which will soon be available for £300 as well as Sony's Xperia X which is a lot more expensive but equally impressive in terms of performance.

Sony Xperia X is a result of Sony Mobile's refreshed smartphone offering after the company killed off its Xperia Z, Xperia M and Xperia C range of smartphones to concentrate on a single product line. Even though Xperia X is a capable smartphone, Sony's struggle with the low-cost premium phone market seems to continue unabated.

OnePlus 3 launch: All you need to know

Dimensions and weight

Yesterday, OnePlus announced that the 3 was among the world's slimmest smartphones with a thickness of just 7.3mm. While this is true, Vodafone's Smart Premium 7 beats it to the punch with a thickness of just 6.99mm but the Xperia X is a bit thicker at 7.7mm. All three phones are equally matched in terms of weight as well, weighing between 150g and 160g, with Sony's Xperia X emerging at the lightest of the three, weighing at just 152g. However, considering that Xperia X features a 5-inch display compared to 5.5-inch ones in the other two phones, its is probably heavier if we look at the overall dimensions of these phones.

Processor and RAM

While OnePlus 3 rules here with a potent combination of an octa-core Snapdragon 820 processor and 6GB of RAM, Vodafone's Smart Platinum 7 offers a not-so-powerful but a strong combination of a Snapdragon 652 processor and 3GB of RAM. Sony's Xperia X also comes with a very similar combination as the Smart Platinum 7, featuring a Snapdragon 650 processor and 3GB of RAM.

Cameras

The rear camera in OnePlus 3 comes with a 16MP lens, HD Mode, Auto HDR and Dynamic De-noise along with Optical Image Stabilization and Electronic Image Stabilization. The 8MP front camera also features a Sony IMX179 sensor. In contrast, Xperia X comes with the same camera set that features in Xperia Z5 phones. The rear camera is a 23MP one with a Sony Exmor™ RS sensor, PDAF, 5x image zoom and a 24mm wide angle lens and the front camera is a 13MP one with an Exmor sensor and a 22mm wide angle lens. Vodafone's Smart Platinum 7 comes with a 16MP rear camera with super zoom and Phase-Detection Auto Focus and a 8MP front camera with flash. In terms of camera resolution and features, Xperia X clearly offers the best camera set among the three phones.

Battery life

No matter how good a smartphone's specifications are, the true measure of its capability is how long can it run on a single charge. We recently reviewed the Xperia X which comes with a respectable battery but a temperamental battery software which not only offers incorrect estimates on how much longer the battery will last but the battery flow is not consistent as well. Based on this finding, we are now sure that just how powerful a phone battery is does not guarantee a seamless performance. OnePlus 3 comes with a 3,000 mAh battery with a battery saving feature called Dash which helps the battery charge from 0 to 50 per cent in 30 minutes while Vodafone also offers a similar battery setup- a 3,000 mAh capacity along with Qualcomm's Quick Charge 3.0 feature. Given that both are fairly competitive setups, we would wait to review them in real life conditions to gauge their overall performance.
