S4 I9500 huge battery drain

Hi guys I am on MEA firmware. My ph is 2 weeks old now but since day 1 battery drain is a lot. Like today I disconnect chsrger at 7:30am n till 6pm only 23% battery is left.
Usage wise EDGE is on all d time. V lightly use mainly WhatsApp n viber. Not much calls sms or even gsmes. Browsing videos etc very minimal.
Settings show screen is taking up lots of battery. M using auto brightness most of d time.
Is this d normal battery time for S4 or mine is different ? If so kindly suggest ways to improvr battery time. Thanx

S4 - Battery drain - Google and Others
Hi. (I'm only sharing my experience with the intention to hopefully help some user's).
Here is what I did. It seems to be fixed.
Here it is:
1- I went to = Settings > Application Manager
2- I tried to find anything related to Google. (Like: Chrome, Drive, Earth, Google Account Manager, Google Backup Transport, Any thing that has a Google on the name. etc... etc.... plus Hangouts, Maps, Picasa. (The apps you'll find will depend on each user). Do a clear data on everyone, plus click uninstall. Click yes or ok if any questions pop up.
3- Besides Google, find one named Downloads and anything with Market. Do a Clear Data. Uninstall anything if there's the option.
4- Don't worry about uninstalling, ahead you will install everything back again.
5- After all this, remove your Google Account. (Sync before removing as you want)
6- Hold power button and Restart it.
7- Now, create your Google Account back again. Check every option about notifications and syncing stuff, and set it as you wish.
8- Open Play Store. Update everything.
9- Hold power button and Restart it.
10- Now, check every option about notifications and syncing stuff on each of the apps updated and or installed. Set it as you wish.
11- Do the same above about ANY other app you have installed. Some apps don't have many setting's options, but many do, and those some use to create Log's, or connects every once in a while to the internet. It's a pain in the ass work, but I did it.
12- Hold power button and Restart it.
Finish!
About the heating process, like inside the pocket, is most probably because something is trying to find a way to connect, like GPS, WiFi, Bluetooth, etc. Make the right configs for your needs on each and avoid this.
Like the app in the picture attached, "android sensor box". Only 10min on background, and got 5%.
Every once in a while the heat will occur, ans its normal when on use of anything.
Ps:
1- I my be mistaking, but I guess after doing all this, some Google Apps, are a bit different. Google Latitude is gone, and this use to drain a lot of battery.
2- Make sure about what you leave on for Syncing or for Logging, or Registering data like temperature or any other kind of app. There are many doing stuff on the background.
3- Even whit the GPS always on, it is really used only if there's an app trying to use it. That's one of the arguments I have for checking all setting from pretty much every app you have.
4- Check your auto start apps.
Hope it help.

*Guide* : Better battery life on htc one [Updated]

Just want to add on here for more battery saving tips
Guys I may have found an easy way to curb Google play services or any other spyware app to stop them from doing things like Access location or mobile networks which may further wreck yr battery life There are 2 guides here , Guide 1 (maybe redundant) and guide 2[updated] . if u think one of these guides works better than the other in yr bbs or gsam results, u want to use just only or a combination of both
App: Guide 1(maybe redundant)
LBE security master ( english translation is xposed module, so install that first)
Install and open the app
Go to permissions , Google play services all permissions , location and choose block or prompt
U can do this for WiFi and 3g too
I can also set all apps to prompt this way u know which apps want to access what when not opened . And deny them when they are running in the background . Also u will know if Some apps will access eg. Location when opened .. as o fnow i have made all apps to prompt mode so i can identify which app is running wild,. So far none
this part here may significantly save battery
first get this app : disable service
choose google play services and untick
analystics service
checkin service
NLPlocationreceiverservice
google location service
dispatching service
2) Then using app system tuner
go to google play services - receivers
checkin.checinservices$reciever
checkin.checkinservices$triggerreciever
checkin.checkinservices$tSecretCodeReceiver
checkin.eventlogservices$receiver
update.SystemUpdateService$SecretCodeReceiver
update.SystemUpdateService$Receiver
loginservice.migrateToAccountmanagerBroadcastRecei ver
*After this u wil only see GCM service runing in settings-apps -running
yr apps should work fine using battery saving location type
3) Disable Google syncing , u tick individual items in settings - accounts and sync - yr Google account
4) get greenify paid version
Tick wakeup timer colescaling in experimental features
Update:Guide 2 . this guide here may do all a of the above in a better way
1) install paid version Greenify and latest xposed
2) go to experimental setings and tick "reveal hidden sync"
3) go to phone settings , autosync, clik on yr google account and u will see new options with a *.Now can choose watever u want to be disabled
4) Also u can do the same for Facebook app or any other app with * entries . . U don't need Facebook acting independently . BlinkFeed will update for u the feeds
5) use Disable Service app from the Play store to disable:
Google Play Services
com.google.android.location.reporting.service.Repo rtingSyncService
(ReportingSyncService)
Google Services Framework
com.google.android.gsf.subscribedfeeds.SubscribedF eedsSyncAdapterService
(SubscribedFeedsSyncAdapterService)
here is the screenshot in phone settings for google and facebook example

For what's app I don't think so .
Lbe security English translation is an xposed module . Look for it in the exposed download section

battery goes down while sleeping

well i think something else is drainign yr vbattery u need to check for kernel wakelocks and apps which have in built in ads constantly pulling data
anyway LBE security has option to block all ads in apps. look for that section and do that
and also in LBE security under 'location: main section put all apps to prompt and see which one is doing something when u never opened it

i tested only google maps and it works , not sure about google + as i dont use it
re-enable the google location manager service if something does not work. I think this service controls the settings- location where u choose the 3 different gps options

just realised that yours could be a batery calibration problem ( if on custom kernel )
what rom are u using and the version ? all i know is that some roms/ kernels have a battery bug reporting problem or they have not adjusted to the battery cycle. try to recalibrate the battery . u dnt have to full charge it and drain to zero, just drain to zero a few times around 3x . see how that goes .

Oh yeah i had the same doubt. .im running paranoid android 4.6 beta and stock kernel. .im doing the calibration now.thanks!Il do that and let you know

Well my battery drains 1.2% per hour when idle.. I'm running Google edition with elemental kernel.. Downclocked to 1.5 GHz and undervolted a little too.. WiFi is always on!
Btw the best I can achieve is 0.8% idle but that's on 1.2 GHz and it's not worth it, things feel kind of slow!
I haven't tested the suggested tweaks, maybe sometime.

Better battery life especially during standby or when screen is off
Hi Lewonsky!
Since you seem to know a lot about achieving a better battery life i thought i would take your help if you dont mind.i decided to try out the HTC extreme power saver mode last night since its supposed to disable all syncing of background data and save a lot of battery.And i'm not sure where the problem lies here but it seems to be even more worse with the extreme power saver mode turned on.It's lost 17% during the 8.5 hours i was asleep and for the entire time it was on extreme power saver mode only. .Ive even attached a screenshot below where it indicates that it was in deep sleep for 99% of that time. .taking this into consideration is it really supposed to lose so much battery overnight on extreme power saver mode?any help would be really appreciated thanks!Im on viperone 7.0.1 and stock kernel.I also tried draining my battery to 0% a couple of times as you advised me to calibrate battery. .If you have any other advice or suggestions on how to get a better battery life especially during standby or when screen is off it would be great. .i already am planning to follow that you have mentioned in a couple of threads of yours regarding this. .Thanks again for all the help!

I have noticed the extreme power saver is buggy in 4.4.3 Rom . At times it didn't turn off the data . So I have reverted to 4.4.2 5.11.661.8 Rom . This is the only version according to me in which extreme power saver node works correctly .
Try reflashing the firmware

sometiems rom and firmware xcombination may cause problems but very rarely unless there is a bug with the firmware released by HTC
the battery i think uneed to input some codes in the dialer it will shhow u battery health .
anyway not sure how reliable is that.
try to change roms and see if the battery still behaves that way.

I don't know. But try to use the firmware Intended for yr device like 6.13.707.1 . I just flashed it. Avoid the European firmware,, in my opinion it doesn't work well on Asian devices and causes a bit of battery drain.

Cellular network strength always red, sudden battery drain.

Hey guys, my ZenFone always has a red cellular network after flashing any custom rom. Only on stock rom it's fine. It's always red no matter where I go, and it's draining a lot of battery.
So on another day, I turned on airplane mode and left it overnight. And then when I checked my phone in the evening, it drained a lot. But towards the end it was shown to be awake, which caused a huge sudden drain.
I have Greenify which prevents background processes, but I doubt Greenify itself takes up much battery.
Anyway to figure out what's causing this problem?

Calibrate your battery . (Simply use any app from play store that can do it )
For red bars : put on 2 sims it will solve the problem .
For wake : use wakelock detector or any similar app and see which app is keeping ur device awake . Force stop that or uninstall it .
Greenify : you can check ur battery stats for Greenify to see how much it consumes (use xposed based feature , its feature rich )
Also try to change your governor it will help you extend few mins of usage . (Use kernel aduitor)
Thank you.

Thank you for replying.
-I'm charging my phone to 100%, will update results after calibrating.
-So even after removing second sim card the red bass won't come back?
-I think I found what caused my device to be awake: Kernel Adiutor. I switch off 2 cores of my CPU using this, to temporarily fix the freeze issue(unlocked bl), but after about 20 minutes I'm unable to switch those cores back on without a hard reboot. Leaving then switched off overnight caused a huge drain, as shown below.
- Greenify doesn't use much at all.
- Governor changing is something I feel will lead to the same result as switching off cpu cores.
EDIT: The pic shows Wi-Fi was on the entire time, but in fact it was switched off the whole time... wonder why
EDIT 2: wakelock detector doesn't work, says 'failed to perform task at the moment, try again later' as soon as i open it.

1: if you remove SIM then yes red bars will come .
So insert both the sims that's the fix .
2:read about different governors ,it will help you understand them , as you mentioned about turning off cores that was simply HOTPLUG governor (my guess ), yes it causes huge battery drain in ZenFone . Try other governor ( yankactive,wheatley, conservative x ........)
3:I think your Wi-Fi is in scanning mode always , so suggest you turn that off .
To turn that off simply get into location setting , tap on the 3 vertical dot (options ) , there would be scanning option set according to ur preference .
Hope this would help you .

2: Suggest you to turn on all the cores .and use the default governor .
3: Try turning on and then off the Wi-Fi scanning option .
4: Also you can perform a clean install of the Rom (if nothing helps and send a logcat to the Rom developer)

That wasn't the problem, the problem was that my battery suddenly drained due to my phone being awake with screen still off, but thanks for replying anyway.

So battery calibration did nothing. And it seems the cellular signal strength being red is something of a bug for RR for the Zen5, but the person said it doesn't impact battery at all. But in my case it does, it causes over 300 mAh drain in a day.

Terrible battery - no deep sleep

[FIXED]
The problem was related to the motherboard. With the new one everything works properly.
Hi,
I have seen a battery drain for a one week. I can't stand with it. The battery drains very fast - especially at night because I got over 30% battery lose with everything turned off! I tried to wipe cache and factory reset but these ways didn't work. I dunno what's going on but it makes me sick. I think that the phone doesn't go into the deep sleep, because "Android System" takes a first place when it comes to the battery usage. Actually the battery is quite new (97,5% real capacity) so I guess that's a problem with system. I don't want to root my phone because of the knox privileges.
I attached a screenshot which shows a night usage of the battery (when I unplugged - battery percentage was 75%).
Any solutions?
What I tried:
- turn off Wi-Fi scanning
- turn off Bixby
- battery saving mode
- wiping cache
- factory reset (but I've used a backup - if that matters)
Didn't work.. So please, help me

i have exactly same problem for about two weeks. Android system is the first place in battery usage, even before screen, if i dont use phone too much. On samsung community there more people with this problem.
Maybe problem is polish version? Też jestem z polski, jedynie problem mam na modelu z plusem. Jeśli znajdziesz rozwiązanie napisz je proszę (if you find the solution please write it here)

Try not to use a backup, just for a dat or so.

Do you use OPV CSC? Or XEO? Which security patch? My is september. I unfortunately use OPV (Orange) and maybe that's the problem. Can you o provide a link to the Samsung community discussion?
I did a totally clear factory reset yesterday and it still doesn't work. ?
My sot is around 2h...

Same issue with me also.. stand by time is around 8-9 hrs only..
Not sure what happened.. service center ppl asked me to change the battery only..

Turn off GPS and your battery will last forever. On my S8 plus I only turn on GPS when really needed.

I have exactly same problem in s8+. Android system draining my battery for about 2 weeks. SOT in 2-3h.
@vemangor i've got Xeo and problem exist.

2 weeks? Lol my problem has occured for the same period. I have no Idea what I can do with it. The biggest drain is always when the screen is off and I don't use my device .
Nothing actually works... the worst battery experience I've ever seen

same for 2-3 weeks..
1) display
2) android system
3) android os
4) device standby

Maybe you have apps that run in backround,just try to disable few apps(apps-show system apps- disable allow backround data usage),and disable body sensors from GmsCore from google,you can find it in permissions.
I dont have gmscore and playstore anymore on my S8+,and i have 8 hours SOT,these are the apps that i use right now,i've debloated everything that i dont use and i have Alexisrom 5.6.1

I use the stock rom. I do not wanna to install any custom because of the Samsung Knox. I did factory reset for few times and no one fixed the battery problem.

How to prevent apps from sleeping?

Hi all, I've ran into some difficulties with the latest Pie update. The problem is, I couldn't keep my adguard app running because the system will force it to sleep after about 24 hours or so (maybe even less, I didn't pay attention to the timing).
Even after I set it not to optimize the app, turn off battery saver and adaptive battery and lock the app to ensure I didn't accidently close the app. But it still goes to sleep.
Hence the question, HOW DO I KEEP IT RUNNING AT ALL THE TIMES?
I would really appreciate if you could help me out with this. Thanks.

That's the problem, I don't root.

Try turning off the battery optimization,
Try going to setting ---> Battery ----> Battery Optimisation ---> More (top right corner) ----> Advance optimisation --- > Turn off Sleep standby optimisation . IF this doesn't solve your problem, you should turn off deep optimisation too!
Give it a try.

Thanks for your help anyway. Any other way? Anyone else?
