Sony Xperia Z1 battery problems

[ramar]

Hello,

I bought my Sony Xperia Z1 about 3 weeks ago and recently I have started having problems with battery life (since about 2 days). When I have received my phone everything was good with battery, I discharged the phone till it turned off and then charged it back to 100% several times. The problem with the battery that I have is that it dies pretty quickly. For example when I went to sleep one night the battery was on around 98% and the next morning I woke up it was on about 30% which is just ridiculous. Before the problems with the battery there battery only dropped down by 2%, and now it suddenly started dropping by 50% or more. I really don't know what to do, I was thinking about exchanging it as it is still on the warranty and also my father has exactly the same phone and he hasn't got any problems with the battery. So if you could help me somehow, if you can of course, because I don't want to exchange as it will take a while before I get it back. 

Thanks a lot

Check which apps are draining your battery 

settings > power management > battery 

also check the graph

that isnt a direct link mate.. i cant view it.. you have to share it and allow the premisions for anyone with the link then share that link.. this one says no access.

You have to make the files/pictures public

it seems that indeed there are apps using your data and/or wifi while Idle, you could check the list and see which apps are doing so

thats a pretty reasonable graph for usage tbh... if you ask me your phone is operating fine...

ill upload my graph shortly to take a look. i use it quite heavily throughout the day. with wifi and data at various intervals.. but as woolie said.. if you really want to juice the battery you need to turn off all the apps that run in the background using the data while your screen is off.

The apps that are using my data (even though its off) are:  Android System, Android OS, and McAfree Security. Not sure if that's what you were asking.

Oh, and also what does "idle" mean ?
