ZTE Axon 7s detailed: dual camera, bigger battery and Snapdragon 821
This is how you do it - ZTE finally revealed the full spec sheet for the Axon 7s and it’s even better than we expected. We knew of the upgrade to Snapdragon 821, but the dual camera on the back was a surprise.
The 20MP camera sensor is still on board (1.25µm pixels), but is now joined by a 12MP Sony IMX368 sensor (1µm). Both have a bright f/1.8 aperture, phase detection autofocus, and 4K video recording, all this while the front camera hasn't changed (8MP).
Besides the slightly faster chipset, the ZTE Axon 7s also gets more RAM than its predecessor - 6GB. It’s not quite clear if there will be a 64GB storage option, though the 128GB one is certain.
The battery also got a small bump - from 3,250mAh to 3,400mAh, matching the OnePlus 3T. And unlike Mr. T, the Axon has a microSD slot, a QHD screen and Google Daydream compatibility.
The price has not been revealed, though. Presumably it will cost the same - $500 - or more than the 128GB version of the Axon 7.
