Xperia Z3 sudden battery drain

[RishabhRekhi]

Hi, I am new new to the forum and this is my first post. 

I have an Xperia Z3 D6653. Lately I have been noticing that the battery has been draining faster than normal. I installed a battery analyzser app for that too. 

A few observations:

• The battery drops from 12% to ~4% in matters of seconds. 
• When the phone is on charge at 96% it jumps to 99% and comes back to 97% and then again 99% and suddenly 100%. This was using the wall charger. 
• The main point which made me write this post was my idle drain. I sleep with my phone 100% and wake up at 52%. My WiFi auto sync and GPS was on. No bluetooth or NFC. 

I understand there is battery drain but 48% is not understandable. 

Thanks in advance.

Boot on safe mode and check again

Hi

Since google play services is using the maximum battery, it's for sure that one of the app is the culprit. ( in the second screenshot, apps usage is 74% of the total battery used  )

Uliwooly gave the best possible way to determine it.

Usually a normal phone restart could also help fix the problem.

For the abnormal battery % readings, check this thread

Had same problem with Google play services eating the battery life.A repair using pc companion fixed it for me.Problem only started after the. 28 update

@uliwooly

I did try that, and a relatively better result. Only 12% drain on standby for the sametime.

Correctly stated that it is an app. Is ther a way to identify it?

I tried to uninstall the last few apps I installed. Hasn't helped much.

Also, the irregularities like battery dropping from 12% to 4% in a 10 seconds

or

Battery fluctuating between 96% and 99% even on charge seems odd to me.

I had the same problem. But the only way to fix it is to disabling Google Play Service. And then un-installing and re-installing it.

But the bad side of this is that you have to re enter your Google account and password after reinstalling it.

Hi also new to forum. Have the same problem batter went from 81% down to 14% overnight. Highest battery usage was android os at 13% but that's about it. Any ideas?

I found the solution.

I'm a low user, not someone who is always on their phone but I used to use about 50% battery each day and it suddenly changed to about 95%.

I have done 3 things: disabled auto updating of apps;

clicked on the sony lounge and whats new popups and chosen the disable options (lounge now shows in app settings as disabled, maybe 'what's new' isn't able to be disabled completely but I did choose some sort of disabling option when I got a notification);

changed the phone's wallpaper to the sony one which is nearly all black.

Now, with the same low use, I'm only using about 10% of the battery per day.

I'm connected to wifi at home and work and Virgin (EE) when not.

What a result! It seems all those continuous and annoying app updates were the main problem and disabling as many auto updates as possible is the way to go.
