M4 battery drain

[Rathan]

Using this phone for a while, I am facing unique problem where battery drains from 100 -98 percent , 67-65 percent, 25-22 percent evertime I charge it.
Any solution please. Can I ask for replacement if it cannot be fixed?

I'm having the same problem. The graph dows not appear because I've just repaired the phone using PC Companion with no success, but this is the proportion of the consumption. The device is active and heating 100% of the time, I've been trying to solve this for a couple of days and looking online it seems to be a problem a lot of people are facing and there is no solution. I just bought the phone and I'm very disappointed about having to return it.

Hi,

I bought my M4 Aqua Dual in August 2015...and have this super strange battery pattern. within 30 min of charging the batter is down to 95% without using and steadly continues to drain without using it much. Sometimes it takes over 4 - 5 hours to charge.

Need an immediate solution as real fast as I'll be travelling and cannot go around with a phone that takes over 5 hour to charge and the starts draining immediately without use.

It's Android Core Apps. Takes 25%. All rest below 8-10%. This app also contains over 300 Mb of data that I can clean. Seems to be a caching feature going bananas. Can hardly use contact book and sms.

@Eduard7

I am using my camera for 10 minutes and it starts getting hot. I love sony but my samsung never had this issue.
