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

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.

Horrible Note 4 Battery Life. Android System Draining Way Too Much Battery.

So I have a T-Mobile Samsung Galaxy Note 4, I got it back in October so yes I have "broken in" the battery. I have checked out several other posts and tried pretty much everything. I've turned off bluetooth, NFC, any and pretty much all useless Samsung features (smart stay, turn over to mute, multi-window), I've got a black wallpaper on for both my home and lock screens, I have greenify AND DU Battery Saver, I ONLY ever use data as I have unlimited data and my building has a shared wifi network which I don't trust, I have tweaked Sync in the settings menu to only sync crucial info from all my accounts (google, facebook, email, whatsapp, etc.). So far the BIGGEST battery drainer is Android System. It is always number one. I've had days where I've decided to push the screen-on time to its limits and have used it nonstop. Screen consumption only ever gets close even if I use my phone nonstop Android System is the biggest offender. I've tried keeping power saving mode on 24/7 but that has not seemed to help at all. I've disabled S Health, S Voice, and several other apps I never use like Google Play Newsstand. I am at the end of my rope I despise this phone for its claim to great battery life but its absolute GARBAGE real world performance. I consider myself lucky to get over 3.5 hours SOT. At this rate I might as well have an iPhone 5. I have no idea what to do.
Here's a list summarizing the things I've done to improve battery life:
Bluetooth off
NFC off
Multi-Window off
All email sync set to Manual
Sync for every account adjusted to isync only crucial info
Pitch Black Wallpaper
Power Saving Mode (Not Ultra Power Saving) switched on about 90% of the time
Using Greenify on all Power-Hungry apps
Closing most apps upon finishing using them
Using DU Battery Saver in order to monitor battery activity
Never use Wifi
No Multi-Window
No Touch Sensitivity
No Side Key Panel
Wifi Calling feature disabled (I never use wifi anyway)
No Download Booster
No Smart Stay
Animations switched off via the Developer Options
Tried using another battery (similar if not identical results)
I'm still getting at the very best if I'm somehow on a miraculous streak of good luck that day: 4 hours of Screen-On Time. It is ALWAYS Android System usually followed by Android OS and then an app or two before Screen (because my SOT is so pathetically terrible)
I love this phone, the display is beautiful, the camera is fantastic, it runs seamlessly (on Nova Launcher that is), BUT I despise the battery life. It has made me resent this phone and I'm seriously considering switching to the iPhone 6 Plus as that has comparable battery life and with it running iOS I doubt the OS would destroy my battery the way Android has been lately. What do you guys do to get such good battery life from this phone? I've tried everything I know!! Please can you help guys?
I'm also attaching screenshots from one of the BETTER days.

I would consider rooting and installing a custom rom, poprock I would recommend for keeping touchwiz.
I don't know.. maybe your battery is the problem.. When I was on stock I had the same issue, but i varied in a weird way. With poprock, battery life has been amazing.

A few people have this issue. I really think it has to do with a corrupt file that was flashed. Maybe no fix but a new phone. If part of the pit file got damaged no fix but samsung.

the battery distribution and the SOT is what I usually get too.. but the usage of 7 hours is too little. I always get over a day..

I'd already seen your thread. It wasn't too helpful for me unfortunately because I'm not rooted. Half the terms you guys were using "Odin'd, pit file, etc." I don't understand at all. I'm running Nova Launcher on this phone. Just typing this comment my battery has dipped from 78% to 74% this is ****ing ridiculous I'm sick of this **** phone I might just switch to iPhone. I'm done with battery raping Android.

I'm in the process of fixing this. I think I may have figured something out. I have been slowly working through freezing applications to figure out what is causing the battery drain. I've made some progress. I really think it is an issue with lollipop system apps.
I am now having a slight dragon from cell standby, but the Android System drain is getting capped. Been in this single charge for 17 hrs and Android system is only 7%
Once I get a bit more firm information I will post my findings.

Some suggestions: check out your Google settings first. Disable Google Now and uncheck their location monitoring settings. Also freeze Facebook (use the website instead). Finally ou can disable sync altogether for a while in case other apps are hammering away through it. Test your battery under each of those conditions. Good luck, be patient, take your time. If your battery is good eventually you'll get to the bottom of it. Use Better Battery Stats to monitor. Most people get fantastic battery life. I rarely use 40% in a day. Over night (8 hours) I lose 2% - that's also a really good thing to watch. If you are draining badly at night, you have major wake locks occurring.

Thanks I'll try some of that but my problem is that I shouldn't have to do all of this crap! God it seems like we HAVE to revert these superphones back to pre 2000 dumb phones in order to get any kind of a decent battery performance from them. Samsung just haaaaaad to make the screen 2K. If they'd kept 1080p it might've been better! I might as well just switch to the iPhone 6 plus if I want ZERO functionality from my big screen phone. God I hate this Note 4 and I'm so jealous of people who don't do anything like this and still get 5-7 hours of SOT with their Note 4's. I'm beginning to think they're full of it honestly.

Nope. Either replace the phone or wipe and start over since u not rooted very little help.

If you are scared of root just stay stock rooted. Not a slight at Bacardi. He answers the questions better than us.

I am have the same issue with battery drain from Android System. I have see that issues is there when WiFi is enable the battery drains faster. When WiFi is off and using mobile data it drains normal.

I will be watching this carefully. I have the same issue. Always Android system and Android OS in the top 3 battery drainer. Only, issue I have is I have to use WiFi at home. T-mobile service drops to Edge about a half mile before reaching my neighborhood.

If you click on the Android Systems within the Battery usuage section. It will give you more detail, and show you what services, or packages are using it. The. You can take it from there.

This is what I have right now.

Nexus bricked (already got new one) and battery question

So hi all
I received my first Nexus 6 yesterday, got it charged, didn't even set it up properly (no sim card installed yet). Screen pops up to say ther's an update available to 5.1. So I did that update. Mid-update an android shows up, laying on his back and "Error". Rebooted phone... Bootloop on "optimizing apps".
Got new phone from store today, everything works. But I don't want to update again and have the same issue. Anyone knows something about bricking the Nexus 6 with factory updates? Wasn't planning on rooting or anything else. Is there any major reason to update to 5.1?
Secondly, I was reading that the Nexus 6 has a very good battery life. That's the main reason I switched from my iPhone 5 (before I had android phones) to the Nexus 6. I fully charged it today, spent 20 minutes on the phone and already 5% off, only WiFi enabled & bluetooth. Three apps installed: Facebook, Messenger & Instagram. Does the phone still have to break in or could it be that the 5.1 update fixes any battery drain issues?
Many thanks in advance!

Any tips to prevent it from bricking again? It's a brand new phone in a brand new package... Don't want to go to the shop again tomorrow saying it's broken again. And I could fix it by adb & fastboot stuff but I don't want to void my warranty yet.

the battery drain is mostly related to how you personally use the phone, how you set it up, what apps you install and use, and your phone/data signal quality. keep your phones brightness down for better battery.

Regarding battery life, Facebook app is a huge battery killer. I suggest using the mobile site. Battery life is dependent on many things, including signal quality, apps installed, location settings, screen brightness, etc. I regularly see 5-6 hours of SOT. I keep location set to battery saving. Ambient display is turned off, because I use a custom ROM that enables the LED notification by default. My brightness is kept between 30-35% with adaptive brightness enabled. Also, I'm either on WiFi or a strong LTE signal.
Regarding your misfortune with the OTA soft brick, it is not uncommon but I doubt it will occur again on your new device. If it should, return it again. It is of no fault of yours. You should always update, as important security and system features are updated.

Thanks! Facebook wasn't even between the battery usage yet. Because I wasn't logged in yet. Messenger and Facebook (& data signal) were the apps that drained my iPhone the most, sadly enough.
Currently I was on WiFi with data disabled. To how much days does 5-6 hours SOT time translate in days? 1 or 1.5 days .. 2 days? (for you). I was having high hopes with Android again but my newly aquired Moto 360 drained in 3 hours from 80% to 6%... with almost all features turned off. Hoping to get this stuff fixed.
So I should just try to update it again?

I'm in the "extreme" category as far as usage goes. So, my 5-6 hours of Screen On Time translates to about 15-18 hours of use/standby. For less frequent use, you should easily see 1-1.5 days on a charge, if not more.
Yes, update. There's nothing you can do to prevent it from happening. Well, maybe not nothing...
You could unlock your bootloader, and never worry about updates again.

a little story about facebook.. the last time i had facebook on any of my devices was in 2011. i had it on bith my nexus phones and tablet at the time. as far as i could remember, it always drained my battery. i had it on my nexus 7 for 2 months. one day i noticed it drained 25%. the funny thing was that i never ever logged into my account on the tablet, ever. i started niticing that it drained anywhere from 8-30% battery, without me ever using. after a week or so of this, i uninstalled the facebook app from all of my devices, and have been using the site since. btw, facebook is one of the top 5 apps that will drain your battery, even if you dont ever use.

my phone uses about 5.5-6.5 hours sot. for me, thats about a day, but im a very heavy user. we all use our phones differently, so 5h sot will mean different things to different people.

my phone uses about 5.5-6.5 hours sot. for me, thats about a day, but im a very heavy user. we all use our phones differently, so 5h sot will mean different things to different people.

Oh okay. Maybe I should remove the Facebook app. I only use it when I'm bored. Will leave messenger installed for now.
In meantime I successfully installed 5.1. Now on to 5.1.1 or does it have the same battery drain issue as the android wear one?

Note 5 Battery life on Marshmallow

Hey everyone,
Hope you all are doing good. So I wanted to ask as to how your battery life is after updating to Marshmallow as compared to lollipop?
Mine has actually gone down and I am really pissed and worried. Have posted on G+ communities asking for solutions but haven't received any worthy solution so far?

Getting slightly better battery life with MM here...
Sent from my SM-N920C using Tapatalk

Slightly better on LP than on MM for me. I was getting more than 6h SOT before and now I can get only more than 5h. Cell standby is there most of the time and eating some ( not too much probably but still annoying) battery.

Having the same problem here and still haven't found any solution
I am losing nearly 8 to 9% per hour on standby time without touching my phone on MM compared to 0.5 or 1% per hour on LO

hi,
Firstly, battery life overall on Marshmallow has been overall quite good (for me) .!
Similar to Lollipop.
But then all my Note range 2,3,4..5 has and still has, very good battery usage overall !
If i had battery " life issues" I would have done a bit of "investigating" or what is causing battery the drain?
Also, did you do a clean update or dirty?
I would also, monitor batter usage ....?
eg with a app like GSam battery app etc etc. (Play store, free app)
(Before you start blaming Marshmallow or system.)
You must also remember, some 3rd-party
apps might not been optimized for Marshmallow .. yet. ?
I have already experience this, with some 3rd party apps on Marshmallow !
If its system causing issues then remember , system apps, wifi, location always on , Facebook or some always on app, etc might be the reason.?
I would then consider taking drastic steps... factory reset and reflashing official stock Rom again.
You don't have to be rooted to do above !
Bottom line, you have to find cause /app /system app, and deal with it accordingly.
Good luck

Did you try the deep sleep fix by Dr.ketan ?
Note 5 which have knox triggered have issues going into deep sleep which will have huge impact on the standby time.
Try applying Dr.ketan fix on this page :

Hey, thanks a lot for such a detailed reply, really appreciate it.
I actually did do somewhat of an investigation after reading some posts and articles online. I am unable to find the real reason the battery time has decreased after I updated to MM. I did a clean update using ODIN to flash the latest firmware. It was the cambodian version that first came up. Later on when a Saudi Arabia version came up, I flashed that since I got my phone from Saudi Arabia. I performed a factory reset aswell and set it up from scratch.
I don't use the facebook app so I have disabled that, location is also off and wifi settings have also been optimized. When I check my battery stats, I don't see any app or any system app even that is consuming unusual amount of battery. "Screen" is always the one to use the most battery and is followed by "Cell Standby" and "Android OS".
I don't know about the third party apps much to be honest. There aren't much in my phone except for the usuals like snapchat and messenger and some other apps but none of them are consuming unusual amount of battery. I have turned on the app optimization so many of my apps are always optimizing.
If you have any more idea as to what should I do, let me know and i'll surely try it out.

My knox isn't triggered I have checked that because I have kept this phone in it's stock state since the day I got it. Previously I used to root my phones the day I got them but this time I around I wanted to see how stock will treat me so I didn't root this one.
Dr. Ketan's fix is for knox tripped devices and asks for root etc so i'll probably pass on that.
Thanks for your reply.

HI,
It's good to see you are trying. Believe me we have to pinpoint any possible "wakelocks" that you have.Only then should you be able to tackle issue. !
Have you installed even GSam battery app ? It has a section to pinpoint " app suckers".. (their wording.) (No root needed)
Have you looked at your deep sleep data?
eg a app like Cpu spy should tell you such info .? or is your device always running in a low power state .? (no root needed)
Are you rooted ?
then yes issues it can be endless .!
Anyway ,
If so ,you can install battery apps eg Wakelock dectector or Betterbatteries ,to get more info ?
Then there is apps like Greenify or your stock Smart Manager ,that can tell you a lot .or nothing ?
have you disable processes with an app "Package Disabler" if so you can have "knock on" effect .(re battery drain )
Please note ...
that the stock battery app helps, but its very basic.Your Snapchat and Messenger ,is it set to auto update .?..thus causing wakelocks ,as apps has to check Status/updates.?.(battery drainers .)
Good luck

Hey,
Thanks for your constant support. Yeah I know that is the only way this issue can be solved.
I will install GSam right now and see what it has to say.
I was thinking of looking at the deep sleep data, haven't done it yet. Will install cpu spy as well.
No I don't use my phone in a low power state.
Nope. Not rooted. Thinking of doing so, what do you say?
I haven't installed Greenify after the update. I think buying such a heavy spec phone and then limiting everything kind of ruins the whole point of it, don't you think?
Haven't used package disabler cause it confuses me as to what to disable and what not to.
Yup my apps are set to auto update. The battery app doesn't show them using too much battery though. How to disable this auto update I'm kinda unsure?

hi ,
Rooting ...its your choice ,its your device .!!!!!!
however ,i can answer you in this way .
All my precious devices , ..eg Note 2 ,3 , 4...and a Note 8.0 tablet ,is rooted and i am really enjoying the "rooting "
capabilities /power ..to do what i want ..!
That said you would notice i did not list Note5 ?
No ,its not rooted ( had device since October 2015 )
Yet ,my Note 4 ihave ,same day ..rooted .
So it depends .?
I have found no need to root Note5 ,as i am happy overall with the whole experience.!!
smoothness ,speed ,themes ,browsing experience .!!
No irritating bugs ( Just sorted the few bugs i had out ..factory resetting .)
this time it worked .(Previously ,seldom worked ,factory resetting )
I ended up always, flashing Rom with Odin to fix .
Battery overall ,
eg .sleep mode ( night time ) i get about 9../10 hours with +- 3% drainage .
I am a "meduim power user" and get with overall use a day ...+- 35..40 % battery drainage ( +- 24hrs)so i have about... 55/ 60% battery left at end of the day .(eg emails weather updates ,twitter ,forums /web browsings ..Google Play store updates , Themes store etc etc . )
I feel i can achieve this as my device is tweaked right !!! Not obsessed,as to as some members with battery SOT ( time on ) .
Ok , Auto Update , Play store ?
turn off in Play store settings ,(see screenshot .....this taken with my Note5 , screenshot )
Gsam battery ,( see other 2 x screenshot ( taken on my rooted Note 3 , with custom ROM )
also notice in (re Note3 ) GSam setting screenshot that in sleep mode i got about 4% drainage re 10hrs standby !
Good luck

A lot is about the use...now I can get the same I had on LP with normal (for me)use :browsing, Tapatalk, some games, some Wi-Fi calling, texts, only Wi-Fi ...I wouldn't get the same with only games or Facebook or equivalent battery eater. Stock unrooted MM.

Hey,
Yeah I know. I have been a rooting fan since the beginning. My nexus 5 was rooted so was my note 3. This is my first phone that I haven't rooted, it's an accomplishment. Exactly, I am satisfied with my note 5 as well. Was very very happy actually but after the update the battery life has been a bit of a disappointment, otherwise it's great in terms of speed and smoothness etc. Even my iPhone lover friends are quite amazed at the performance of my phone with lollipop and even more with marshmallow.
I did the factory reset after some members on the G+ note 5 community pointed out but that didn't make any difference for me.
I did as you suggested, downloaded those apps and used the phone after 100% charge. Since yesterday was a holiday so I didn't use the phone much as I was on my laptop. So after taking off my phone at 12 in the noon I used it somewhat and had more than 50% left even when I woke up today. Used the 50% and right now I'm on 15% here are the screenshots of my usage. I usually charge my phone as it reaches 40 and charge it to around 80 85%.
I hope you can help me after seeing these. *fingers crossed*

Hey,
Thanks for your participation. Yeah I know all the depends on the use and I don't think my use is too heavy. As you can see in the screenshots I attached in the comment above. I use a little bit of social media, no Facebook though. Whatsapp, Instagram, Snapchat, g+, flip board, fb groups, messenger and some internet surfing and some texting and a little bit of texting and some short calls. No games. I have one two but I hardly play them.

hi,
Well we can try and id culprit /reason.
In app GSam top right in your screenshot you have time on etc.
You have to press drop down small icon and list will appear of options.
see screenshot. Then its up to you to monitor different options ?
Good luck

Hey,
I only have 3 options there, probably cause I'm not using the paid version.
I was thinking of downgrading to lollipop to see how it performs there now? Do you know how I can do that? Since I remember that there was a bootloader change when lollipop arrived and so after updating to lollipop, going back to kit Kat was quite difficult. Is it the same for marshmallow?

Also check via Google or so YouTube video how to do it.,!
Yes, the bootloader would have been updated? (. i think..)

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).

7.0 B378

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

I am also having really bad drain on B378. Far worse than I had on my previous phone p9 lite.
Android system is eating battery. I have done 2 factory resets now.

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.
Sent from my EVA-L09 using XDA Labs

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?
