Battery drains faster with Lollipop

[Stenbocken]

Has anyone else noticed that the battery drains faster with Lollipop, lasts now 2/3 of the time compered to before upgrade. All battery saving settings are set as before.

What app do you install on your device? I suspect it could be one of the app that maybe the culprit. You can check in your power management to see what is exactly taking up the battery. I don't see battery issue with lollipop though I seen others complaining the same thing like you did. Personally I actually find the battery performance improve rather than suffer. The longest I ever got up to is around 3 days 14hrs and I am still left with 18% of charge. And I didn't even enable stamina to achieve that. My usage pattern never change and I am very sure back then during kit kat my phone didn't manage to stay up this long. Max is 2d 10hrs or so and I am probably only left with around 10% or less. So on average even with slightly heavier usage I still can squeeze 2 days out of it.

Almoast none app has been installed,

chrome and android system appear to consume 30% each....all the others are in a very low consumption

What do you suggest.

May a reset to factory settings fix the problem?

Hi,

I also have very bad battery life in lollipop compared to kitkat (kitkat 3-4 days, lollipop 1 day). I did a repair with pc companion. Here is what I found out:
I only get bad battery performance if I'm using mobile data and not wifi. I don't use my phone very often, it is mostly in standby with stamina enabled, and I whitelisted a few apps in stamina to receive notifications (facebook, gmail, etc). When I check the battery stats, it show very starnge 'mobile radio active' for those apps which uses internet. For example I used Google chrome for 10 minutes, than I switched off the screen on my phone. 5 hours later it show that Chrome has more than 5 hours 'mobile radio active' !!! (Chrome is not even whitelisted in stamina) And it does the same for all internet apps (gmail, my internet radio app, etc.). So it looks like, lollipop can't close connection for apps if I'm using mobile data insted of wifi.
This issue has been reported to google months ago, but they turned a blind eye on it (https://code.google.com/p/android/issues/detail?id=165558 , the priority of this issue is small !!!). So it is seemingly an android related google bug, rather than a sony related bug. Can sony please apply some pressure to google devs to start looking into this issue? Or is there something that sony devs can do to workaround this problem? Any help is much appreciated.

I'm guessing this has already been reported, but I'm having serious issues with my Xperia Z2 since the Android Lollipop 5 / 5.0.2 updates. 

When I use mobile data, the battery drains and gets very hot. I've gone from having 2 / 2.5 / 3-day battery life (if I switch to ultra-stamina when I'm running low) to struggling beyond a full day. I've also noticed quite a lot of battery drain even with mobile data turned off. I've turned off background data (or queuing it, whatever it's called), but that's not really made an impact. 

Is anyone else having the same problems? Will this be fixed in the next Android update? If I downgrade to KitKat, will it void my warranty?

Reinstall lollipop with PCC and report back in couple of days, also stay away from taskillers, antivirus, battery apps, etc.

Thanks for the quick reply, man. Will try this now.

There is very likely a rogue app running viciously in the background. I had the same issue when I loaded an app from Play Store that caused my Z2 to heat up. Than I discovered this app: Cooler Master. Basically shows you the CPU temperature and what app is stressing it. Helps me find a few rogue apps that I had and after I uninstalled them, my phone stays cool and stable. 

If there is no rogue app causing the heat up, than very likely you are having a hardware issue. See this link for more info: cell-phone-gets-hot.

Hello.

So I reset my phone to factory settings to see if that would do anything. It actually has made my battery slightly worse. For example, I charged my phone this afternoon. When I took it off charge, it told me I had 22 hours of battery life left – a far cry from the 2+ days I used to get on one charge. I don't know what to do. 

Sony makes these claims about battery life, but it's no good if an Android update can so seriously compromise my battery / power management. Is there ANYTHING that can be done about this? Does it seem like a fault? Or is it purely Lollipop and Sony's version of the OS that's to blame? I bought this phone in good faith because of its battery life – I need a long-lasting battery for work – and now I'm lucky if I get a day's use out of it.

Hi same issue here. Fingers crossed it will get better. I'll let you know in a week or two.
