I recently bought a Xperia Z2. I had heard a lot of praises about its battery life that it stays up for around 2 days with normal usage. But my Z2 seems to be draining battery very fast. It lasts only for around 15-20 hours with normal usage. It also loses battery on standby. Its on Lollipop 5.0.2 build number 23.1.A.1.28. I have also come across many posts saying that lollipop has reduced its battery life a lot. Is this true? and is there any fix for this? or should i go and replace the phone? Any help will be appreciated. Thank you.

I have noticed a fast battery Drain on my Z2 since it updated to lollipop as well. I just sent my phone to the Sony repair centre and I'm sure to get it back this Tuesday. I'll let you know if they fixed battery issue

Same here. Lollipop drains battery. The only option to repair it is to downgrade to kitkat.

Strange thing,my phone is old at least 11 months and battery on Lolipop is more or less similar as in kit kat.

Just bought my z2 yesterday my phone cpu temperature is always 55 some time go to 60
I think battery drain fast to i lost 4% in 10 min and battery temperature is 38 Dunno where is the problem i hope some one help and sry for my bad english
Phone running on lollipop and no apps running just screen and data on
My Z2 only starts overheating when I play Hitman Go, or while watching videos while the phone is charging.
Try leaving the phone on stamina mode. Also your phone could be struggling to find data towers hence the extra power Drain.
Try downloading watchdog lite and see what is abusing your cpu. In my case it was Facebook messenger. It got my phone to 67 degrees Celsius and used around 50% of cpu just by running in background

the Z2 has been noted to have a hardware issue that causes overheating
it lacks a heat sink and a heat basin where as newer xperias have this
sony has improved the temperature throttling in lolipop

I kept managing to hit 65-70 by doing next to nothing. Quashed Google now wakelocks and turned some of its features off. Now hitting 55 max. Try that. I'm on KK by the way.

I also noticed that on 4.4.2 I got crazy overheating issues but the second I updated to 4.4.4 and higher they went away.
I'm not really sure if Android version changed anything for me... Basically, when traveling (brightness around 70%, listening to music and using LTE with poor signal I get ~43°C on battery). Another example... Streaming internet radio over LTE for longer periods of time = frying pan. So, when I don't really need LTE I use 3G and it's about half the usual temp. I would get... But as I said, it depends on signal strength... About CPU/GPU... Well, let's say that the recent discussions about 810 overheating make me smile

wait for sony's update, bro.
It might be useful if you posted some battery stats from a battery monitoring app, such as gsam or batter battery stats. Then we would be more able to help with troubleshooting.

its not you.. got a HTC M8 its on Lolly and wifi, BT blah blah lasts for days.
My new Z2 with just Wifi on goes from 100 to 70 over night. Now with some batter saver maybe 4% drain.
So its a bug for sure.. Should not drain this fast.
I disabled all google services
try a search on this
"mobile radio active, kills battery"
My battery drops 6% overnight. My Z1 was at 99% in the morning(sometimes even 100%). I was going to buy a new battery, but now I see I'm not the only one. I have never used kitkat on the phone to compare.
I am agreeing on battery draining. From D6502.
Please be aware that abnormal battery drain can occur when using apps not supplied with the phone. You need to check their CPU drain as with other phones and remove them to increase batterylife

Well it sort of explains itself. Battery life on my Samsung S7 is about 2 days with my usage when connected to wifi. When I shut wifi off and only use data I get a max of 1 day .... the battery drain is significant.
I am pretty sure that this is a android bug, because this is the second mobile I am experiencing this battery drain with.
Use to have a Sony X3 Compact and bought the X5 Compact cause I loved the battery life so much. Much to my disappointment the battery life of the X5 was about half that of my X3. I even experienced it draining a full battery and switching off during one night. I of course was convinced that the X5 must have had a defect battery and got it changed. It didn't help and after getting the device changed for a brand new mobile with no better result I demanded my money back.
So know I bought the S7 and the only thing I can pin this problem on is the "phone radio bug" that exists on the newer versions of android. My HTC One Mini and Sony X3 Compact running KitKat have normal battery drain running 4G. My HTC X5 Compact and Samsung S7 handsets are just going through the battery like crazy on 4G even though they should have much superior battery life.
It amazing how many people have this battery drain problem and yet there is absolutely no sign of any official statement on this to be find on the internet.
Please ..... anybody have any experience like this.

I might add I live in Cambodia. I don't know if this would have any influence? Probably shouldn't cause my mobiles running on android version before Lollipop haven't had this problem.
What do you think about the P10 battery life ?
I'm not happy at all ! With my P9, I loose 2 % during the night (8 hours). With my P10, I loose 10 % (same settings, same apps,...). I have difficulties to finish my day with a charge... My max is 4 hours of SOT. There is a huge difference between the P9 and the P10...
My last hope is a good update quickly ! I'm looking at the S8 now...
What do you think guys ?
I have exactly the same battery life on P10, as i had on P9... But EMUI 5.1 is not killing background apps, as it was on 5.0 - so maybe something drains your battery?
I read that some updates are probe to be pushed to P10 owners... that will solve the curent problems.

Have you done factory reset after OTA, or just Cache wipe ? Mine after update seems to drain battery faster....

For me it's the same. Phone is still completely useless when wifi is on.
Android OS is killing my battery... Very high drain!!!
After updating to B130 from B100, my battery got much better. Still having 20% at the end of the day (11:00 PM) with the same usage pattern (on B100, I had to plug it into the charger/power bank) as was 20% on my way home (5:00PM).
How many hours of screen do you get daily?
I guess Huawei missed something in their otherwise very good battery management system on this phone.
To those having issues with draining, you should remove facebook and facebook messenger.
They have managed to give the background processes that slip through battery management systems.
Even when one check in battery monitors like gsam, one see only Android system as the culprit whereas facebook is the one causing the wakelocks.

Around 5 or 4.5 with some custom settings.

Yes I am also facing the same battery issue...
I think the battery life time of p10 is more better than p9. When i'am using p9 its OS kill my battery timing . Mostly after updating the mobile its life time is decreasing.
Since the .219 update I've noticed the battery life is draining very fast. I barely get 2 hours of On-Screen-Time and when the phone is on standby it will use 20% overnight, meaning that I have to charge 2x a day. When I first got the phone I would charge it once a day and it would hold atleast 1,5 day on full charge.
I've tried: 1) System repair, 2) factory reset, 3) battery stamina mode help only a little, 4) contacted Xperia support that didn't really help.
Anyone experienced something similar?

Since updating, I'm getting a lot of ANRs for file intensive apps and they seem to drain the battery faster.
Cellular performance seemed improved on my carrier (US T-Mobile) but it's a hot mess roaming on Vodafone UK.
Yes have been noticing mine draining much faster than it used to. Not as bad as having to charge 2x a day but I now barely make it through the day compared to getting 1.5 days previously.
I have similar feeling. My battery works worse than before. And I do not mean the fact that of course as every battery it is getting worse over time, but it's life dropped suddenly after update
same here... :-(
got the version 61.1.A.11.88 2 days ago, seems better now

Battery life still poor on this firmware, it drains much faster than my Xperia 1ii.... If enough people complain to Sony then they might do something, I have made a complaint to Sony UK here, Cheers
