[Q] Bad battery after 4.4.4 update

My awesome HTCm8 has gone from being a ph with great battery to one that is down to 20% by end of day.
I did wipecache on recovery mode then finally did factory reset yesterday.
Still not much luck. Android system and Android OS and cell radio consume most battery. Before the update my battery usage would only show cell standby and WiFi and phone idle. Now it's a long list including Android system and Android OS. Before update I could go 2 days without charging.
Anything I can do? Do I need to factory reset again? I want my awesome phone back. Btw I was forced to update due to constant update notification which kept plumetting my battery by keeping the phone awake. Orelse would have skipped the update.

Android OS battery drain, no deep sleep.

Hey guys, I'm having severe battery drain with my new Xperia XZ. The phone basically never goes into deep sleep and I have no idea what the cause could be. I'm on the latest firmware. These are the battery stats overnight when I wasn't using the phone.

I have the same problem with my xz

There must be something wrong with the software, since I'm also experiencing twice the time of phone activity than screen-on time. I have contacted Sony Customer Service and they advised me to do factory reset and since I had no time to do it lately, I can not say if it worked. If you have spare time to backup and restore your data, you should go for it. Keep me informed of results

Not here
Sorry to hear that guys.... My xz is running with the last software update also, but the battery drain during night doesn't exceed 4-5%. Wifi always on, alarm and stuff....

I have done a factory reset and used the pc program to repair the software and still android os is taking many %

Factory reset doesnt changed anything

Every time you factory reset and/or flash something it takes a while for the android OS to rebuild caches etc.
Please see how this goes over a week and then see if there are any issues.
If you still have no deep sleep or wake locks then you will need to provide logs in order for anyone to have an idea what is causing it.

No issues with battery here. When I got my phone I reinstalled the OS right away through the Sony companion. Maybe try that. Will check what happens overnight since I got the phone just yesterday.

I didn't got an issue with CPU, but my XZ battery drain over night is about 4-5% (did check and close/disable all apps and connections ) and by day use is too high (may not last a full day with facebook checking & web surfing frequently, full at 7am to 20% at 7pm ). (I did use Z1 before, and that is quite terrible cuz Z1 did last longer when it was still new)
Hope nougat update fix that :'(.

I've had the phone for just about a week, so I'll give it some time and see if it settles, especially considering my brother's Xperia XZ doesn't suffer from the same issue. Thanks. Well at least the Nougat rollout has begun.

Update:
I did Factory reset with software repair (via Xperia Companion) and after reinstalling my apps and whole night charging I saw little improvement...
My 2nd thought is "Smart Cleaner". Since I have installed some really badly made apps like Facebook, Messeneger or Snapchat, my observation is that they don't like to have cache cleaned. So I have turned it off and magically my issue is gone. Deepsleep 95% of time.
IMHO every performance improving software feature must have some issue...

does the drain fixed with new N update?
im still using MM and suffering from this prob badly

Good point. I have to try. I have the same problem
2h SOT
Happy D6633 user

I do hope Nougat fixes it. I guess we'll find out soon enough.

Very poorly holds the battery in this phone. I am almost collapsed!
Happy Xperia XZ & Z3Dual user

Despite the battery size it does what was advertised.
No root,
Not unlocked
No custom ROM
All info is stock Android N from my XZ. I can get easy 4 hours SOT through the day.

I don't bother with stamina, it's not the same since before 6.0. Just cripples performance. Huawei have somehow managed to implement stamina style features into their 6.0 ROMs. If Sony manage to do the same I'll use it again.
But then, I've had over 3 hours screen on today and still have 57% left, more than happy with that given my cell reception is never over 2 bars here.

I seem to have phone idle and Android system as my main culprit. Running android nougat. Any fixes yet? Phone doesn't seem to want to enter deep sleep

Anyone else experiencing poor battery?

I bought my Pixel in Nov 2016. Battery lasted on average about 1 day & 10-20 minutes based on my personal usage. In the last few weeks, it barely lasts 24 hours. I haven't added any new apps. My battery usage info doesn't show anything unusual or an app consuming a lot of battery. I downloaded GSam Battery Monitor but that doesn't give details on app usage unless you are rooted which I am not.
Have others also experienced poor battery although the phone is not even a year old?
Any ideas on what it can be? I haven't changed my usage either (I only monitor it on weekdays since that usage is basically the same each day).
Just an example here: took off charger 52 mins ago and it's already at 89%.

What software are you running? If you don't get the OTA for 8.0, I'd enroll in the Beta. This will prompt you to get the official release at this time. Once that's installed, I'd Factory Reset data and start from scratch.
Alternatively, you can uninstall apps one by one to see if there's an increase in performance/battery life. Also, maybe try wiping cache to see if that helps.

Yes mine went from 5-6 hours SOT to maybe 3 1/2 to 4. Horrible. I've flashed countless factory images. Never abkr to figure it out.

I wouldn't expect it's related to the age of the device necessarily. I only just got my Pixel a few weeks ago and it averages about 4 hours SOT over 24 hours with little left in the tank. It's got a small battery.

Mine is terrible on Oreo

You have to give the software about 2-3 days to learn your usage so that it can set everything for you, if you just installed Android Oreo, then, it's going to be at least a day or two before your battery corrects it self.

I have been on the Oreo dev preview, back to Nougat, now back on Oreo and the battery life just has gotten to be terrible. Factory wipes every time I load a new version on Android.
I get about 1.5 to 2 hrs SoT in a 12 hour period and it just about is dead. I have surrendered to the fact that I will just never had good battery life as long as I own an Android phone and I charge them any chance I get.

Personally I use Wakelock Detector on a rooted phone, but it may be possible to get information without root using ADB.

The Wakelock Detector instructions for not having root are more thorough.

I am still on Android 7.1.2 running the latest update - NHG47Q (I think this is the latest). I have not tried the Oreo beta but would hope the battery life will improve since that is one of the new features.
I have heard that one should factory reset when going to a major update like 8.0. I just hate to reinstall everything (apps & settings) from scratch. (I am not rooted.)

Shouldn't have to do that... I've never bothered and it's not caused me any issues. I think people who suggest you do that are probably the same ones who suggest you wipe cache and dalvik cache all the time (burn).

The screen takes an awful lot of battery on this device.

My battery life was getting worse, and a factory reset a few days all fixed it.

The only issue with that is reinstalling all apps and settings.

Standby time is immensely better but lost an hour or so in sot

The screen uses the most power of almost any phone, the Pixel being no exception.

My battery drains really fast after I upgraded to Oreo 8.1. 30 minutes of Youtube used up 20% of my battery. It used to be only 10%.

I am,went from 5.5 on nougat to 4 on Oreo to 5 again on 8.1 dp1 and back to 4 on final.....sot of course. No change in usage

try getting rid of Back up to Google Drive took my SOT from 2hrs to 5 very odd

Battery Drain on Android Pie?

Hi All--
I've been on the Android P Beta for a while.
However, starting with the final beta that was released (and now on the final version of pie) I've been experiencing really quick battery drain.
Tried a total wipe and restore, and the same thing. My wife (also the pixel) isn't having those issues at all.
Thoughts?
(nothing shows up in the battery section)

Yes, I had great battery life. Then once Android Pie was released, jumped on the beta to get 9 sooner. Then got the upgrade from beta to final and battery life is horrible. I did not factory reset, I have battery saver on and it doesn'tseem to matter. If I leave on standby, no issues. If I use the phone, it can bleed as much as 10% per hour! Unacceptable. I may try factory resetting, but idk...

have you allocated sufficient time for app battery optimization?

I also have a pixel, Android 9.0/Pie (bought it brand new three days ago) and think battery is draining very (!) quick.
Yesterday I had roughly 2.5 SOT (with battery saver enabled) and this seems consistent with what I can expect typically. I did factory reset and have tried restricting "background activity" for my frequent apps - seems to make no difference. Obviously it had not time to do full battery optimization yet I guess, but I doubt it would mean a that big difference?
Saw a thread where someone mentioned it seems CPU-freq is high/inc. very rapidly when just tapping the screen (GPU-0%), and I can agree with that although I have not the prev. experience of what to expect.
My previous experience is with Xiaomi mi6/mi5 (lineage 15.1), similar usage would give 2x or 3x SOT (however with some other hw-issues.. ).

Reinstall factory image & see if that helps.

Flashed factory image without -w/"wipe". Will that do or should it be "full" factory reset to make sense?

Thank you for your information, I will stay on Oreo.

I don't think it would make a difference. The user data is on a different partition.
You could try flashing the image again, without Magisk or any other additions.

I had used up 50% with only 21 minutes screen on time.
I noticed the app Device Health Services, was constantly active in the background.

I had the same like the OP: everything was fine until the last beta came, and battery is draining faster, phone gets hot from even the smallest usage even in the prod release of android pie.
I was thinking it has something to do with being about 36 degrees (summer time....), but it is the same even in cooler temperature rooms. It's like if the phone is constantly doing something in the background, but only if I use it.

It has been a few days since I upgraded my Pixel 2. Battery life is noticably worse, maybe 20-30% more battery drain in a day than what I saw in Oreo.

I notice the issue as well. I did factory reset after update it's been a week. I was on beta and started noticing battery issues in the first beta and throughout. I decided to install Accubattery to track my battery usage and ended up with a result.
My phone states the battery is in good condition but this app says otherwise. I guess it's time to change the battery along with cracked screen!

i'm curious if my battery is shot as well... Seems like after I purchased my used Pixel.. the battery is not as lasting as I hoped for the smaller pixel phone... I may try one of those battery testing apps to see if it will tell me its current health..

I normally welcome up updates, but this update screwed up my battery life so bad. I mean everything was perfect until the update. Now the battery drains so fast I can watch the percentage count down like a timer and now when the battery gets anywhere from 15-40% the phone will just shut down.
I would like to go back to oreo, but it's such a pain in the ass having to back everything up and flash a ROM considering I haven't done that since before I bought the pixel

I have the same problem. I hope Google can fix it.

Wow, that is not normal. Stock android 9 with root and elemental kernel.... I go back to android 8.1.0 and wait for feature releases

I think I found an Draining App/Setting
I disable the RCS Service on my Phone. It can be found under Messages >> 3 dot Menu >> Settings >> broadcast News. Disable it.
And then Bluetooth and WiFi scan disable.

Same here, crazy idle drain after pie, only 50% deep sleep, tried factory reset and no luck

Try BetterBatteryStats. People in that thread spend their free time analyzing logs to tell you what's eating up all your battery life.

Having trouble with battery life - BIG TIME (Pixen-OS)

Hey,
So I'm a user of that ROM for a while
Recently noticed very very hard battery drain.
Means I can leave my device for a night and it will go down for example from 100% to 65% easy .
I deleted all unnecessary apps , did lots of checkups , even disabled Volte to try and same thing .
Here are some screenshots below of BBS.
Getting sorta like 1.5 hours of SOT .
Please help me

As a pixen user myself, i haven't faced battery issues on the latest builds, hell even overclocking the device i still have solid battery life. I'd recommend a factory reset to see if things clear out. If things don't clear out with a factory reset, reflash the latest builds alongside a factory reset in the process of doing so, If neither of those options work, try updating the oos firmware and reflash pixen on both slots.

Have you ever considered the possibility That your battery is going bad. Cuz even my battery is actually gone quite bad. Have to change it in a few months.

The only way to know is to try to run OOS for a while to compare. If it's also bad, then your battery is bad. BTW, you don't need to make a separate thread for this. This isn't a ROM support page.
