[Q] Huge Drop in Battery Life after 2.17 Update

Hi all,
My battery life on the One X has been great before the 2.17 update. Better than the average being reported on this forum.
After 2.17 it plummeted to 14 hours or so with barely 2 hours of screen time.
Nothing was changed after the update on my end. Same apps, etc. All on stock.
What are my options? Will a hard reset solve it?
Thanks.
Update
The factory reset did the trick. Battery is back functioning properly and I did get extra juice out of the 2.17 update.
If you do find a weird drop in battery life and the ONLY change is that you updated the firmware, a hard reset may solve it like it did for me.

You should go thru a couple of charging cycles before complaining about battery time.. everytime you flash a new rom or update the phone the battery has to calibrate ( as far as i know ), and that takes about 2 - 4 recharge cycles..
in case you already done that, then check you sync settings, brightness if its too high, or low.. Maybe you are used to be on wifi instead of 3g ?

It has gone through over 10 full charge cycles.
Sync is off. Brightness minimum.
Wifi and 3G usage patterns are similar.
Just noticed that Phone Idle is consuming a lot more.

Maybe it's the new radio which is affecting your signal, try flashing an older radio. My battery life is better on the new firmware.

i first of all found the battery life had dropped, i ended up resetting the phone and it got much better, i think some old app was getting lodged in the memory and preventing deep sleep.
i ran it for about 2 weeks before i decided to wipe.

@nikzDHD
I suspect it could be that. My provider does not provide that strong a connectivity. But that is something I can't change for the next year or so.
@audiobookman
I decided to wipe it today. Also waited about 2-3 weeks before deciding enough is enough.
--
I did a HTC Battery test and found that my battery was in good condition and performed way better than their baseline. So, I went on to wipe the phone clean and started from scratch.
It was not a painful process actually. Most of my stuff are on the cloud (Google/Dropbox/Skydrive) and the only things I had to back up was the list of apps I had and some settings from apps like Tasker and Minimalist Text. I got everything back up and running within an hour + (reinstalling 60+ apps and getting them setup the way they were takes time).
So far, battery seems a lot better and back to the former period but, it is too early to tell. I'll give it a week of use and a fair amount of full charge cycles before commenting.
Will update this thread then.
If anyone has other ideas please sound out. Thanks a lot!

I do a factory reset after every OTA because of the reasons you mention of this thread. After it battery life seems to get better or at least not worse as on previous firmware version. I hate doing that but it seems the only way

[Q] Battery life poor since JB

Hi everyone,
My One X used to have brilliant battery life. I didn't turn on the screen that often throughout the day, but I was able to regularly check the news, send and receive texts, make a few calls and - crucially - keep my Wifi on for the entire day. With this setup, I was regularly getting 4 or 5 days of usage without having to charge my phone. However, as soon as JellyBean came along as an official update, I grabbed it... since then, I'm lucky if I get a day and a half out of it before I need to plug it into the wall.
I'm not running any custom ROMs: just whatever I get through official O2 OTA updates. Battery usage says that 36% of my drain is due to Android OS, with another 20% due to Maps. The rest are tiny, only 2 to 5%. Now I understand that a new version of Android might make some new demands on the hardware, but from what I heard, the update was supposed to improve battery life if anything. Even with the new Power Saver feature on, the difference is minimal, with only a few hours standby time gained overall.
Can anyone suggest anything to remedy this, or is this fairly normal? It's not world-ending and perhaps I was just really lucky to get 5 days of use in the first place, but thought I'd ask the experts before I grin and bear it. Thanks in advance for any help or advice.

19 hours and 40 minutes into this usage cycle, I've got 57% remaining. So it's shaping up to be about 40 hours of usage, down from 120 at its peak. Right now, it's also saying that Android OS has used 99% of my battery... and nothing else is on the list.
Does no-one have any idea what's going on?

Did you make an hard reset when you updated your phone?
This is why when you upgrade your phone to a newer Android version it is better if you perform a hard reset

AW: [Q] Battery life poor since JB
I suffer(ed) also under heavy drain due to maps since update to JB. But I'm convinced it's cause of Google Now. Disabled it yesterday and will check whether it gets better or not. Try disabling gnow and see if it gets better. I also had issues with gsam battery monitor in case you use this.

Thanks for this. Your suggestion got me checking for other people having issues with Google Now and battery life. I disabled it as you suggested and I'm definitely seeing an improvement. It's still not as good as it was, but I think I might be able to squeeze more than two days out of it now.

Do you have stock rom? Because I've just upgraded to JB yesterday and flashed a custom rom, and since then my battery is like 3 times more powerful.

You should definitely switch to a custom rom... Ever since I upgraded to JB I've seen a massive improvement in my battery life.. From barely making it through the day to almost 2days of my typical of usage.
Google Now does seem to kill battery as it polls the Google maps app a lot.. So I usually open task manager to make sure it isn't running in the morning background.

STOCK Battery Issues (Tested with GSam)

Hello all. I received my M8 about a month ago, international version and am very happy with it thus far. Amazing phone, gorgeous design; I love it. However, an issue that has risen is poor battery life. Included is a screenshot via GSam battery monitor of my use today. The level of battery after just over 2 hours of screen time is disappointing to say the least. I texted a few people today, made a few calls, read a few articles online, and watched a few videos over WiFi. Basically, no activities that should cause this much drain. The absolute best battery life I've been able to get is 4.5 hours, and that's using minimum brightness and keeping data off. I noticed that the app usage section seems to be the biggest culprit, and have included a screenshot of what apps are running to help you all help me figure out what's going on. The only thing keeping me from unlocking the bootloader and trying all of the glorious ROM's this community has to offer is the fear of me having a bad battery, which I know is highly unlikely. I'm running stock Lollipop by the way. Factory reset was done after upgrade to ensure a clean install. Please, any and all advice and help is welcome. Thank you in advance!

Horrible Battery Life on Nougat

So Just to announce where I am coming from, I am a Sony fan for the past 4 years, Had the Z2 and was totally blown away by the battery life it offered. Then I got the Z5P and even though the battery performance was nowhere near the Z2 I still got through an entire day with it without issues so I was happy.
Then came the Nougat update and all hell broke loose. I am literally getting just 6 hrs of battery life since the update. And even when it is idle it still drains battery like atleast 2 percent every hour.
Also the charging is very slow. I have a quick charger that used to take the battery life from 0 to 20 in atleast 10 - 15 mins. But now it actually drains the battery if I am using the phone while charging. And yes I have switched off the battery optimization option.
Any help will be appreciated even if it is just a confirmation that I am not the only one having this issue, which will at least let me know that it is not just my phone.

There must be some process with corrupted data after de update which is constantly executing something. I recommend you to do a full wipe, factory reset

Oh did not know this could happen. Will definitely try doing a full wipe and see how things go! Thanks a lot!

I never fully trust OTA updates, because it keeps all the applications data and some special case of your current configuration maybe is not "converted" to the new version and causes the programs to behave weird. Have you looked at the battery usage? Maybe you find the process which a huge % of battery eaten, and just wiping that app data is enough

Thanks for the reply! Yeah I looked at the battery usage stats and no specific app is draining more than 2 percent of the battery over a charge. The only things that have taken most out of the battery are 1. The Screen On Time which is to expected and 2. The Idle Phone which takes around 15% consistently in every charge.

after updating to .372 , i learned from internet that this build has battery draining issues. ( i never faced any )
after updating to .376. , the phone is as steady stable as my other xperias (btw z5p is my 6th xperia )
now there is however a catch.
1. if you updated on OTA , this means the update of 1.2gb via ota only replaced certain files from .305 to make it .372 build (android 6 to 7) --- such OTA updates USUALLY ends up having problems (in general) with battery draining issues. Such problems i personally faced during updating from honeycomb to ics. - in short whenever update is available; always install FRESH
2. if your bootloader is locked then use xperia companion to install fresh after wiping all data. (makebackups)
3. if your phone is not rooted then try disabling all un necessary apps under Apps section.
----
Trivia
You cannot compare Z5p with predecessors like Z3/Z2/Z1 and Z since
1. they were always smaller in screen size / resolution and were not 4k
2. They stops at Android 5 / 6 as their last builds and battery life was awesome w.r.t consumption

however some of friends on XDA agrees that .305 (android 6.0.1) (came out dec2016) is the BEST build ever for z5p. addressed all battery issues and it was the final build for z5p on android 6.0.1
even i am thinking to degrade my phone due to ram consumption of N is very high!
this is why xzp has 4gb ram!

I need to know. If I updated my phone to .376 and it's having this lack of battery life, DO I HAVE TO SELL IT OR DISPOSE OF IT BECAUSE IT'S LITERALLY A LOST CAUSE NOW? (P.S. I immediately did a factory reset after the Nougat install completed.)
Because apparently if you updated to this build, then returned to the last Marshmallow build, THE PROBLEM IS NOT FIXED, and reloading nougat will only make things worse. And if you updated to .378, it not only does this not get fixed, it breaks your headphone jack to boot.
Please help. I am freaking out about this battery life. I lost 60 PERCENT IN 6 HOURS OF BASICALLY PODCASTS. ?

Well, after all my trials I flashed MM back and everything is back to normal. The issue is with 7 so not sure what happened to your handset
EDIT: Re-upgraded once again= battery 8 hour life. Go into About Phone, Status and disable battery optimization. The handset reboots and incredibly this morning it was like the old days .

Maybe I'll try that. The best I was able to do was 21 hours with one bar LTE, 6 hour's sleep, and 3h40m screen on time with several hour's worth of Pocket Casts.

i confirm that on build .33 i lost my battery even on stamina mode one percent every 10 minuets over using wifi , it just keeps the battery when device is screen off -_- its horrible i didnt have this kind of problem with .253 and im wondering revert back to MM

Poor Battery Life on Android P

Ever since upgrading to Android P (OTA) 3 days ago I've noticed the battery life is really poor. On Oreo I used to see only 1-2% drain overnight. Now I go to bed with full charge and wake up with only 60% left. The battery drains a lot faster when I'm using it as well.
I used to be able to get 6-7 hours SOT easily. Now I'm not even sure if I could squeeze 4 hours before the battery is flat.
Is anybody else seeing this? Or is this normal considering Android P just got installed and it needs time to "optimize stuff"? But then again, with Oreo I got awesome battery life from day 1.

Weird, I've gotten better battery life..

Better battery here

Interesting. I'll let it run a few more days and see if there's any improvement. Otherwise I'm going back to Oreo.

Give it some time, once adapative battery figures out your usage and adjusts accordingly, you should see better battery life

Try to factory reset ur device this may help

Thanks guys. I'll wait a few more days. If it doesn't improve will try a factory reset

I'm getting better battery life with Pie

Pixel 1 XL could last a long time. Pixel 2 XL was worse and the worst with Android P unfortunately. I upgraded from Beta, decided to factory reset since there was a bug with Wear OS eating the battery. Got a little better. Got some more little better disabling adaptive battery. I think Doze is still in Android P.
Anyway, it's still not that good. But decent.

I am having the same issue.
when I reboot the phone, the battery seems ok.
But when I start using the phone and open several apps, the battery starts draining quickly.
I installed magisk root, should I do a factory reset and not installing magisk?

I went from a day and 17 hours to 16 hours. This is definiately a piss-poor "improvement to battery life."

I'm not sure how much help adaptive battery is going to help. It's meant to limit background battery usage of infrequently used misbehaving apps. If that's not happening adaptive battery won't do much.

My battery life has been terrible. Today I unplugged at 93%. I've been off the charger for 9 hours with 4 hours screen on time. I'm at 23%. With Oreo that kind of usage would have me at about 40%.
I'd rather not have the hassle of having to do a factory reset but I might not have much choice.

It hasn't got any better since I reported the issue.
I think I'm going to flash Oreo instead of trying a factory reset as I doubt it would solve the problem. Maybe someone else could try and let us know.
I'll report back after flashing Oreo. Very disappointed. I thought this was the first phone I didn't need to tinker with all these stuff on. I was really happy with it until this issue came up.

So a few days ago I flashed Oreo only to have it tell me it couldn't find any of my backups on Google Drive during the initial setup. Of course, the backups were done when I was on Pie.
So I had to upgrade to Pie then factory reset. This time it found my backups.
Yesterday I managed to get 5 hours SOT with about 40% battery left. Life is all good now

looks like i'm going to have to do the same. It doesnt make sense how some people are getting better battery and other worse. Are there some of us running apps not 9.0 compatible? might be worth uninstalling everything and adding them back day by day. it'll take a long time though!

same here, slightly better

It appears I jumped the gun. The problem came back yesterday.
The phone loses about 4-5% battery per hour even on standby. I have no idea what's going on; I haven't installed any new apps and usage pattern hasn't changed either.
One very interesting fact I have discovered is that the issue appears to happen only when I'm on Wifi. When I'm mobile data, all is good. So the phone seems to be doing some funky stuff when it's on Wifi lol.
Oh well, I guess I will try to install BBS and see if I could find the culprit.

That is entirely possible. I guess we have apps that have not been written/optimized for Pie? That would explain why some people are not seeing the issue and some unfortunate ones like us are.

I factory-resetted the phone, the issue is still there. I don't have any strange app. It seems that it's just the system that is consuming the battery.

That's very strange I've had the complete opposite, battery life has improved, if reset didn't fix it monitor your apps for unusual battery usage and limit the background activity of battery consuming apps
