Android 7.1.1 + battery drain

azzido — Sat, 29 Apr 2017 19:22:24 GMT

Hello,
I am on Android 7.1.1 now and I noticed a huge impact on screen on time battery life.

Before the update I was having like 6 to even over 7 hours of SOT. Now I am having like 4 hours SOT.
This is a huge decrease. Please note I installed the update via OTA and did not change any settings or did not install any new apps. I am using the phone exactly the same way as I was doing it before.

On the other hand I noticed that IDLE time is much better now. Battery drain from 0 to 1% over night.
I think they've just upped the cpu's (or gpu's) clock when navigating through UI that made the phone so fast and smooth now. Sadly it is impacting the battery SOT too much. I would expect the software optimizations in code rather than simply upping the clocks to get rid of lags.

I hope Sony will fix it soon
Thank you.

The battery is pathetic after this update. The phone is indeed faster but battery drain is insane! I did an OTA update as well and was thinking to to clean install it again hoping for better results but I'm very busy!

My SOT on 7.0 used to be 5.5 hours on average with 15 percent left In juice

Exactly what I am saying, now max SOT is around 4h
How it compares to previous 7h??? It is almost 50% decrease! I hope Sony will react fast to this issue.
Anyway, I do not like new battery graph, it does not show the information for how long in total the phone was working on battery... it only shows remaining time 😕 I noticed that one update is bringing this information and another takes it away.

I had the same problem.... The ui used a lot of battery for God knows what and even crashed. The phone became a nice handwarm.

I did a factory reset (not with companion) and it works perfect now.

I can use Chrome (and other Internet based apps) without making the battery indicator a count down.

The phone is noticing cooler with long use.. Say an hour continu.

Sorry, I know this is not what you would like to hear.

Cheers

Performance is way better for me on 7.1.1, although screen on time is broadly the same, leaning towards six hours....... I'd honestly been slightly disappointed with the XZ until this landed - just odd that not everyone is having the same experience. If it matters, I was running stock UK initially, but picked up some european firmware when reverting to marshmallow for a few weeks (I'll have to search online a little if anyone wants to re-trace my steps). All updates have been OTA since that point. Not perfect by any means, but given the clear bump in speed and the fluency of the screen.....

Is there any difference between companion and factory reset?

You said "not with companion" why?

Are you saying that the speed of 7.1.1 is better than Marshmallow, or better than 7.0?

Re: Android 7.1.1 + battery drain

For me, 7.1.1 is the best it's been period (so both), and the bluetooth issues were worked through by entering into safe mode and re-pairing my devices.

The earlier versions of nougat were a struggle, which understandably pushed some back towards marshmallow generally.....

Are you saying your battery consumption is as good as 7.0 or even better after resetting your phone?

I might do a reset as well if that helps.

Thanks,

That's strange🤔

I mean I could barely get 4 or so hours of SOT!

For what it's worth, I installed the update over the air too. I might do a clean installation and hopefully it'll work.

Check my post. Despite this, I like my Xperia and these bugs can happen with any other phone I owned.

Hopefully it gets solved soon.

With 7.0 i got 7hr SoT

Now on 7.1.1 i get 5.5-6 hr SoT

Standby is normal in 7.1.1 but battery usage is high.

No mater, better performance more important for me. I charge my device at night and if phone can support me along my work period, it is enough for me.

My XZ is rooted and debloated. Google assistant (and qualcomm voice print) are the real problem. Any google apps and services call "google play services". Anybody mentioned have problem with play services, disable Assistant and nearby device.

Re: Android 7.1.1 + battery drain

azzido — Tue, 02 May 2017 19:30:21 GMT

As you mentioned your device is rooted and debloated, and now you are habing lower SOT.
Imagine for the people without root and debloat SOT is now 4 to 5 hours only.

This is a problem Sony need to look into.
Upping the cpu's clock to improve performance is the cheapest solution I would not consider Sony would do. I expected software optimizations other than that to improve the speed...

Anyway, how to disable google assistant?
Thank you in advance.

I'm shocked

Did someone in Sony tested new 7.1.1 software in terms of battery life for XZ before the release?
Do they still have proper QA division or simply releasing from dev directly to Prod???

Re: Android 7.1.1 + battery drain

diego87 — Wed, 03 May 2017 17:03:16 GMT

Whoever can get over 3 hours of SOT in 7.1.1 should feel lucky. After updating my XZ to 7.1.1, this is my usual SOT. The "Phone Idle" battery drain is affecting my phone and it drains the battery while my phone is not in use. I was hoping the software developers at Sony would be able to fix this but its a lost cause..

Hi,

I noticed that under the memory, Android OS is taking lots of memory.

Restarting helps. But it is not the root cause.

So, i disabled to fix it by going to

Settings > About phone > Usage info settings > unchecked it!

I suspect this is using system memory aka RAM and causes the issue.

Try it and see if it helps!
