Battery Problem Xperia Z !!

Guys I have the c6603 model running 10.3..a.0.423...i live in india but got the phone from australia and its telstra branded. the phone has been running well until a few weeks back i started noticing the battery level going down faster than usual...i am not a heavy app user...and in the battery settings, i have noticed that "android system" is using up almost 70-80% of d battery...the rest like 'screen', android os etc. only 5-10%...this has resulted in the phone lasting hardly a day even on minimal usage. So, could anyone tell me why is the phone acting like this ? what could be the possible reason for the android system using this much battery.
Any help would be appreciated.

Well. What i can suggest I have the same sort of issue. Disabled facebook app et al problem fixed.
Well if you want dig a bit deaper then instal app so called "wakelock detector "-> https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en
Hope it will help!:fingers-crossed:

I'm a quite heavy user. I hadn't ever turned stamina mode off since I got the phone. Been using it for a few days with stamina mode off and the battery seems to be way better. When there's a hour or more wherein I won't use the phone I put stamina mode on.

There is a problem with the latest google services framework so that it eats your battery as long as you have location services enabled. So deal with the battery drain or disable location services

* Apps i have: fb, whatsapp, temple run2, vault, utorrent, merriam-webster, firstpost, software data cable, duolingo, zd box, wakelock detector.

Here is your answer! FB is an piece of **** coded app, that is useless on non-rooted phones (Greenify is an must for even using FB app so you can terminate the app after each session).

I had the same problem with battery. I deleted fb with titanium backup and installed friends caster. With location services on and green power premium. I have two days of juce now. No greenify or other apps just green power set to switch off data and WiFi at night and during the day switch it on for 1min every 30 min. Of course when the screen is on I have the data constantly on. No games just websites, music, Tapatalk, Gmail and phone calls plus occasional Facebook browersing using friends caster.

Alrite...i guess i ll have to disable the FB app and see if it makes any difference.

I have just received my phone back from the Sony Repair Centre and seem to be suffering the same issue only more acute. The battery drain is so fast that I can't even charge it unless it is totally switched off, even with the screen off a no apps running it will only charge 8% overnight and with the screen on that 8% will drain in a few minutes.

Newest stock or not?

I'm not sure, it's a C6603, if that helps. I only got the phone originally in about July and it stopped working, wouldn't switch on or respond to any input. They returned it to me working, albeit with the SIM missing, but it had 44% charge, so I put it on charge. It actually seems to be getting worse, I've now switched it off in an effort to get it to charge faster, but having been on charge for several hours it's only up to 56% from 22%, I would guess that's in 7 hours.

Attention!
Guys I just came across this battery issue with samsung s3 users. They have this file "gsiff_daemon" which is giving them battery problems same as ours. the file comes under the name of Android System. Have a look at it and read about it on google. They have a post about it on xda as well.
So I checked if I could locate it in our Z's and maybe rename it or do something, but I wasn't able to locate it even after using ES File explorer. Maybe it is present under some other name and is probably the reason our "Android System" is using up 70-80% of the battery life.
I request some advanced users here to look into the problem and see if they can help us.

Background process limit
Hi all,
Trying this (Background process limit), i think will work, because now i see a lot of more processes in background than in previous releases ( wasting our batery and internet conection..)
I had the same issue in upgrade in a previous release and i solved activating the limitation of background process .
I am trying this solution now
To limitated, go into developer options
Then the 2 option beggining by the end , Background process limit.
I have put 2 process at most

okey ill give it a try & tell u if it works or not have a gud day

Please don't mess with the background process limit. It will have a negative effect on your phone's multitasking and will not increase battery life at all. In fact, it may decrease battery life because cached processes will be regularly removed from RAM and have to reload themselves.
The option is in the developer options for a reason. You shouldn't be touching anything in there if you don't understand what it is.
It's sad to see uninformed nonsense like that posted here when this is supposed to be a place for people to learn how their phone works. ?

problem solved
its not about the software (as many forums try to imply): I went to a lab to replace the battery and now the phone works like expected. runs a full day. not few hours.

heavy standby battery drain

hi
i'm not sure but i think my note 5 is draining abnormally during standby, yesterday i slept at 12 am my battery was 95% then i woke up at 8 and my battery was 60%, is this normal for 8 hours standby?
i noticed that under "android os" stay awake was 5h 39m 32s, could this be the cause?

That is absolutely the cause. Something is holding your phone awake. I would reboot into recovery (turn off phone, hold vol up+home button+power button) and wipe cache and reboot. See if that helps it.

I lose about 1% for every 2 hours overnight. Your usage is not normal at all.

i did it, but still the same issue

Then it must be one of your apps that you have installed holding phone awake. If you can't find out which app it is then i would do a factory reset. That is definitely not normal.

i have tried "wakelock detector" and i found that "google play services" is waking up the CPU a lot during standby and causing this issue, then i searched the issue on google and i found that it is a common issue on Lollipop but i couldn't get the proper fix for it

You could try searching for the latest Google play services apk and install it to see that helps. Also then off always allow scanning in WiFi settings and turn location reporting off.

Mine drains like 2% per hour in standby. And I dont know what the phone is doing.

I know this isn't a solution to your problem, just some extra advice. Make sure you turn VoLTE and Wifi Calling off. Cell Standby is my number one battery drain when screen is off.

I have the same problem with stock kernel. I tried to flash all stock firmware but nothing, same problem. Solve only with arter97 o nobel kernel.

Well even mine is on stock N920C firmware.
Draining alot overnight, I barely have any apps installed.
Android System is using battery not deep sleeping. I tried Package Disabler PRO still same thing.
Any solution?

Well actually i have the N920CD dual sim. The 920C works fine minus the drain.
Trying kernels makes me lose the dual sim option which sucks!

And loosing the warranty as well!!

i have done something yesterday night, i switched off WiFi and Mobile data and i slept with 72% battery, then i woke up 7 hours later and battery was 71%!!!, so only 1% consumed, so i think the issue should be something related to either WiFi or mobile data.

do you have xposed? if so download the module call mobilestandbyfix

My phone with stock rom does that too!
I've heard the update was full of bugs and drains battery a lot!
Whenever I try to look at the cause there was Android Os!
90% to 50% power left if unused.
I did a factory reset and got fix!
Try factory reset that does helps.
About google play services it never let my phone to run smooth just eats ram alot!
I always uninstalled when not in use

Im not rooted and i did once factory reset but it didnt help, maybe i will try it one more time

Why dont you root your device
Get greenify pro ,allow root permission ,hibernate the cause of cpu wakeups !
I did hibernated some system apps and trust me i've got amazing power backup!
Some system apps keep wakeup your cpu and screen in background result in battery drain.
Hope that helps

Huge battery drain

My P9 with B378 is eating my battery like a hungry monster see atached screenshot what can cause this?
Already did factory reset not working.

I suggest you to show us also the apps consumption... But tell us more details... Are you using SD... As external or internal ...Try to format from phone as sometimes excessive consumption is due to old android files on SD ... Also try to locate which apps is draining more gsam battery monitor may help... And you can reflash from zero but this important you read carefully all threads to document yourself... Other cracks here will help you better than me I am quite new on Huawei...

Here ya go

Have you chosed apps to be closed when locking the phone? Only apps i have running when locking is Snapchat and Messenger.
Facebook is a battery killer, maybe you should try Friendly instead?
Also, have you turned off 4G for any apps? Its probably a good idea to disable 4G for the apps you dont use.
I lose about 10% every hour with medium to heavy use (surfing, instagram, friendly, Messenger and so on).

Apart from androidOS the app that consumes more is email... Could be sync problems?.. regarding Snapchat I cant say nothing as I do not use.. as with muviz... Disable Google backup and check on accounts is someone is getting sync errors...These are fist things to check or try to use the phone without those two/three apps to see if are not properly adapted to nougat for some reason... Or boot in safe mode to monitor how it goes

On B361 my P9 had a bigger battery drain than it had before on B182.
Now on N378 battery life is as good as it was on B182. I'm happy again.
So maybe it's an app that sucks your battery.

Thanks everyone problem seems to be solved now, i disabled or removed all huawei or google related apps now battery life is fine

After a factory reset it's normal to have bad drain for the first few days, google is gathering stats .

Resetting your phone over and over does not solve anything.
If after 5 days you still have drain then it must be some app or config.

hi, my huawei p9 also have battery problem but its kinda different. today before i restart my phone, my battery was left at 42% but after the restart the battery was at 1% and the phone switched off. when i charge it, it starts charging from the previous 42% percent. the battery is also very unstable. sometimes it lasts for long and then suddenly drops very fast with the same usage. is it the battery problem or the hardware. should i change the battery?

Yes thats a known bug. Im waiting for a better nougat version to be honest.

Beter to have a Oreo one on P9, becuase I think that Huawei will not provide to us better version of nougat.

HI everyone.
I have exactly the same issue as here, "SystemAndroid" (with multiple applications) is taking much battery. Some time ago it was more than screen took, however I was able to identify couple of things which were charming battery:
1. SD card was used on Samsung phone and then swapped to P9, formatting it helped a bit.
2. I disabled "Ok google function" as it seems it was keeping microphone always on - few percentage less on SystemAndroid.
3. I have turned off history of location - it helped significantly, now SystemAndroid is on around 17-18% while screen is around 26%.
What also I did:
4. Scanning for BT and Wifi is off.
5. Network data always on is disabled.
6. Wifi is set to do not keep it in sleep.
7. Only 3 applications has unchecked cleaning while screen is locked.
8. Removing of messanger, whatsupp etc did not bring any results.
9. Removing SD card also didn't help.
10. Factory reset didn't help.
11. Clear partition cache also didn't help
But still.. most of people has SystemAndroid very low, around 6-9%. I have no idea what to do next to get rid of it. What is strange I set all settings 1:1 comparing with my second phone (P10 Lite) and on P10 lite there is no issue with this. Same apps, same setting, different usage for SystemAndroid. I had this with B397 and now with B398. Any ideas what could be the reason?

Battery drain

Hey there, this happens to me quite often. When my phone is supposed to be sleeping, even though it's on Doze, it's keeps activating and draining battery. Anybody knows if there is a way of fixing it?
I did a factlry reset after buying it.

I used to see the same problem, but after update VTR-L29C432B151 it does not happen anymore

I was fixed with the last update my phone is running great, get a least 5 hours of SOT. And by the way the whole day on mobile data.

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.

This keeps happening to me and in my country there's no update available, i even contacted the support and they told me there's no update just yet, altought I don't understand how that can be.
I'll try uninstalling facebook and messenger but is such a pain in the ass since I actually use those a lot.
Thanks, I'll keep posting.

Try going to lock screen clean up I'm battery options there you can choose to close Facebook and messenger once you lock the screen on you phone that should avoid it from waking up, you can also try to update your phone manually, here are many guides to do so and change also model version i changed mine to c432 vtr l09 and I have been getting the updates after that .

Same for me. Very bad battery time. Build: VTR-L29C432B151
Is this a software bug or maybe battery fault?

Same here. Very bad battery life. Seem like Google Account Manager top on the list under software. Next is Huawei Mobile Services.
I am on B151 firmware. Also i did factory reset yesterday (reinstall all apps manually). No difference.

L29C432B151
I'm happy

I am with B151 too and I dont have drains . I get 5-5:30 of SOT everytime . I dont have drains overnight . I leave it with 100 , 8 hours later still 100% ( wi-fi , mobile data off ) . Probably it's some app draininf your battery !

Yes I use both messenger and facebook along with some apps like youtube , some banking apps + some wallpaper apps . Nothing too special .

Mine max is 2hrs SOT. Can't even last a day. Facebook and WhatsApp is the main culprit, sometimes it's Google play service running because there are apps update in playstore, but funny thing is even if I turn on auto update in playstore it will still hanging there not updating which cause it to wake the device all the while eating battery in the background. I don't have those issue with my previous Samsung s7 edge, battery size both are quite similar... Can only blame it on the huawei firmware is not as optimize as other brands..
I love the phone but if it can't allow me to use my favourite apps and need me to constantly charge my phone, it will be a big turn off..

Try disabling apps after lock screen it's weird that you get such sot, mine even with heavy use and mobile data on the whole day with Bluetooth is always 4 hours or more, right now I was trying a interactive governor tweak that I found on XDA and it's working great but you would have to root your phone and download the elemental x app, evento with out those tweaks my battery was doing great with no drain while screen off what so ever, I'm on the b151 update c432 variant .

hi.unhack installed apps and system apps?or just installed apps?

Hi All,
i experience similar things. the wifi is always showing battery is used, but the thing is that is turned off! wifi, 3g and Bluetooth are completely turned off, but battery is drained by it.
Anybody knows why wifi cannot be turned off or what else could keep it active?
I'm on VTR-L29C432B151

I'm currently showing SOT of 5h 1m with 20% battery left. This is L09 running B171 firmware.
BT is off unless I need it, but wifi and 4g are on all the time.

Battery drain issue after update to miui 11

Hello, I have a battery drain issue after updating to miui 11. I read most of the threads that was posted about this issue. i check autostart, check network type and even tried to press 3 times on miui logo (in the system update) and download the latest package and install and it didnt work. I have battery drain in background (when screen on and off i have this issue)
I have some screenshots of battery drain on night when i m not using my phone (few times that i had this issue). In miui 10 I had around 8 sot and in miui 11 around 4.
https://imgur.com/a/SkY7RN6

Factory reset, debloat using the tool then turn all the MUI task killers off and use Greenify instead. - I'm getting 11hrs SOT with no wake locks.

And why is your advice of turning off MIUI task killer? I'm restricting some apps to run in background and I don't have a problem.

Any fixes? Should I install custom kernel to save some battery?

Revert to miui 10, for me this was the solution. You can also try a strange workaround that worked for me. Set all the apps in "no restriction" in battery settings. It is very strange but is saving me a lot of battery

It seems that's like turning off miui optimisation in developer mode. Many people also said turning off miui optimisation helps you get more battery. I wonder why.
