User C5 Ultra, 27 Apr 2016If u don't use any of mentioned features and still draining fast, the u should go to technical... moreI used to have the battery draining problem too. What i did was i downloaded Sony PC companion app from Sony official website under "Support". I chose repair the phone. After repairing it, I update the phone to the newest Android version 29.1.B.0.101. The draining problem was solved. Now my C5 Ultra's bettery life is pretty awesome, surprisingly even more lasting than a lot of phones i used to own. I hope this will help you to solve the problem. It's just an awesome phone. I like the screen clarity, the camera, the battery life, the sound, the built quality, the beautiful design....

Anis, 13 May 2016It's waterproof !??It's not. One minus of this phone. Everything else is perfect :)
Anonymous, 16 May 2016c5 is the best.m5 is waste phone. I think Xperia M5 is good enough too, by characteristic is better than C5 Ultra (Dual too), but I don't try M5 so I can't said how in use good this phone is. But I think all Sony's devices are good. By the way C5 Ultra is one of the best I think is from Sony, coz everything working good and look expensive and stylish why this smartphone won in Red Hot 2016, M5 did not won :)
