Battery drain is quick - Galaxy S III I9305 (4G LTE + 2GB RAM) Q&A, Help &

Hi.
I've recently bought a SIM-free Galaxy S3 LTE (GT-i9305) smartphone online. I've since changed the battery to an "extended life" 2550mAh one.
I still find the battery draining quick. At 6am its fully charged then by 10pm its down to less than 10%. On my other thread i indicated my normal everyday routine and what i use my phone for. I have had numerous Android phones in the past so i know which ones to turn off, etc.
I understand Chrome can be a drain on the battery so i have disabled it. I have heard of Knox (anti-virus/security) affects it as well but i am not able to uninstall it. I have installed a battery-saving/monitoring app Greenify but i feel it doesn't do anything. Sync is also turned off on my email and social stuff and i put my phone on Airplane mode if i'm at work as the signal tends to be almost zero inside the building.
I also understand the battery tends to improve after a few cycles of charges.
So, Is there anything else i'm missing here?
Please advice. Thanks.

I'm sorry that this is not helping but I have a similar issue.
My battery drains really quick too. It drains loads with screen off, and I get less than one hour of screen-on time. (with stock) It's been like this for a year, but it's getting worse. I get about three times this with the 7amp zerolemon like I should. Charging is super slow too. I'm really starting to this this is a hardware issue. And no, battery stats, wakelock detector, etc. show nothing. Do you recognize any of my problems?

You say you're using greenify, but have you actually tried greenifying apps? That didn't really cone across.
But what I would suggest would be to us betterbatterystats to check what may be the culprit. I assume you're on stock firmware? In which case I would suggest getting titanium backup to get rid of bloatware.
The last option I could think of would be to try out a factory reset to see if there is any improvement.

What have you been doing to maximize battery life?

I thought I might begin a thread for those who have general battery tips, experience with addons, and any other key info that can help some others with battery woes.
I've not had any real problems with battery life from the start-- mine seems to be getting better and better. But some of the reports out there have people with substantial battery problems. Here's what I've done to this point in regards to the battery, and I hope others can chime in with other useful stuff:
1. updated to latest firmware from STOCK via OTA. This OTA marked a clear improvement.
2. rooted
3. xposed installed, with these modules: App Settings, BootManager, Greenify, Unbounce (i think this one's key), Wanam (make sure you disable secure storage or you'll have freezing issues)
4. Titanium Backup to remove some bloat, mostly T-Mobile apps.
5. Look through greenify, unbounce, and bootmanager and filter out stuff that seems unnecessary or hogging resources
6. ALWAYS Let the phone drain to ~20%, and then fully charge to 100% using the adaptive rapid charge (this takes about 1 hour for me). It's important especially when breaking in a new battery, to cycle it properly.
I've seen pretty tremendous battery life since doing these steps, and allowing the system to settle in for a couple days. I suspect it's going to keep improving as the battery ramps up from usage. I have plenty of stuff still running in the background (Facebook, Viber, location, bluetooth for my Gear 2, Sync, NFC) Pretty happy with the last 24 hours especially. My phone is sim-unlocked and running on AT&T- this may play a part in reception and better battery life, but it may be irrelevant.
What are others experiences/steps/frozen/greenified/unbounced/BootManager(ed) etc... let us know!
edit: the attached thumbnail showing screen life, is with the battery at 52% as well
Wow those are some good stats brother
I just drained the first charge to 0 and charged it back up. I'm more than satisfied with the battery on this device!
I spent hours messing with the phone as evident by my screen on time and it just keeps going.

Any tweaks to accomplish that?
The only thing I did was disable all T-Mobile branded apps with the exception of the Mobile Hotspot app. All other bloatware is untouched and still on the phone.
I haven't rooted yet and most of the time on that charge cycle was spent on WiFi. I was trying to learn the phone again, so I was absolutely using it a lot.
The screen on time blew my mind and is the best of any phone I've had to date. Especially when you consider that it was on the first full charge.

At my wits end with my Note5's battery. Please help!

Hey everyone!
I got my Note5 near launch day. I love everything about it, except the battery life.
Basically, I am not satisfied. I barely make it through the day with moderate usage. The crux of my problem is idle/standby battery drain.
This has been a problem for me ever since I got my Note5 and even for some of my old phones (M8 on Lollipop).
The Issue: I'm fine with how the battery drains when I'm actively using it. I'm not going to go into much detail about that, but I'm satisfied with how fast I seem to be killing the battery while using it. The part I'm not satisfied with is how much the battery drains when I'm not using the phone. Obviously, this must be an issue with wakelocks. When you look at the screenshot below for Android OS, it is always wake for more than 2.5+ hours in a 15 hour usage period. Now, I'm not sure if that's normal anymore. I don't remember how it was on KK, nor do I know if that's what everyone else is getting.
The Issues Cont: So yeah I have massive idle drain. (I estimated that I get about 1.5-1.6% battery drain per hour. I charged my phone up to 100% and let it sit idle overnight for a span of about 8 hours or so. It went from 100 to 91 during that time). What this means for me is that, I can use my phone less and less because while it sits in my phone, it dies quickly! On GSam, it shows that my battery discharged 38% while the screen was off! Again, I don't know if this is 'normal'. What is everyone else getting?
What I tried: I tried factory resetting. Nope. I tried reflashing the firmware, factory resetting. Nope. I booted into safe mode and left it idle overnight. Still dropped to about 92% or so, IIRC. I actually had the GS6 Edge before the Note5, but I returned it because of the ****ty battery life. Then I inserted my S-pen backward and broke the sensor in the Note5, so I got a replacement. For each instance, I always got crappy battery life. So I am doubting that this is a hardware issue. I tried minimizing the apps installed so minimize wakelocks, but it didn't seem to help.
What I want: Honestly, I just want to be able to use my phone and have it not drain so much while it's in my pocket or on the desk. I want to be able to go into a lecture for a few hours and come out with maybe 1% drain, not 3% or 4%. And I want to do this without rooting. I don't want to trip Knox, and I'm tired of rooting and spending hours tinkering with my phone to get decent battery life.
Attachments: I uploaded screenshots of almost everything I thought would be pertinent. Please have a look and hopefully we can compare results and figure out whether this is normal for a Note5 or not!

I reckom its something you are downloading is doing it. Add one app at a time and see what it does.

Yes there is something keeping your device awake. Rogue app. First guess would be that Facebook messenger app. Look in settings for your running applications, try to limit those to ones you absolutely need using package disabler. If you don't know what's OK to disable, read through the debloating guidelines thread.

Never let Facebook or Games run in the background and MOST IMPORTANTLY disable location services completely. Keep it on a toggle and turn it off until you need it. Always keep it off or Google will ping your location once every minute. It literally halves battery life.

I don't have the Official Facebook app installed.. And I almost always keep location services off, but the battery still drains as it does..
Use the smart manager app to stop certain apps from running in background and restrict background data for apps that don't need it in the mobile data settings.

My battery is amazing and I can say this as I am a battery guru and have spent countless hours trying to squeeze all the juice out of my devices, which includes eliminating wake locks. If you had root you could figure it out, without root you'll have to start un installing apps 1 at a time until it get's better. Also check your exchange accounts.
I assure you something is wrong as my battery life is the best of any phone I've had.

This probably won't be helpful at all as it is a complete shot in the dark, but perhaps you have an app that is trying to get your location continually since you have it off? Maybe try leaving location on. I never turn it off and I've been getting very good battery life on my T-mobile Note 5.

I also tried leaving location on as well. I can't really see an improvement as well. I actually only recently kept location off.

Battery usage percentages add up to less than 30%

I'm having serious battery issues that just started out of nowhere. I'm currently only getting about 4 hours of light use before having to recharge.
I'd like to look at what apps are using the battery but there are only 5 apps listed and they add up to only 27% (the highest is screen at 12%).
Phone is not rooted and I haven't loaded any new apps recently.
I noticed this as well. I used to use Better Battery Stats when I was rooted, so I didn't know if it was normal to act this way or not. Sounds like it isn't.
Currently having the same issue. Seems like my battery started tanking right around Christmas. I got a Huawei watch and originally suspected that but turning it off and leaving it home for a day didn't seem to help. The battery stats on the S6 are garbage and I can't track down what is going on.
Been noticing the same issue on my G920A. I tried doing a cache clear, but that doesn't seem to have helped. I went through all the running apps and services to try and find anything that could be eating the battery, but nothing seems to be reported that adds up to the amount that's getting eaten.
I use greenify for handling the hibernation of apps when they don't seem to act right by themselves, but since the phone isn't rooted, I have to manually run this operation - and that really doesn't help much anyway. Figured I'd add my experience to this thread just as a means of documenting the situation.

20% battery drain over night || FIXED || SEPTERMBER 13 2018

Somewhere earlier this year I started getting a 20% overnight battery drain. On a few nights it didn't drain, but its pretty consistent. I have tried everything listed on this forum..This drain is definitely not caused by any standard settings. I am really hoping somebody with insight into Oreo might have something new I could try. I know xda user Digisteve is going to showup and suggest more things, and that is also not going to work.
Things I've tried.
- using root to disable logd. (saw this as a process in BBS) Still drained.
- Disabling auto-sync of all accounts. Still drained.
- Turning on stamina mode at night. Still drained.
- Removed google play store, google play services framework, and all google aps - and replaced with alternative China app store. - Still drained. Not a play services problem.
- Turning off wifi, all wifi scanning, notifications of wifi networks etc. Still drained.
- Turning off mobile data and wifi - no connectivity at all. Still drained.
- Turned of location in all possible device settings,. Still drained.
- Rooted the device with Janjan method/kernal. Still drained.
- Flashed different regions. Including (Taiwan, my region, Malaysia, Germany, Swiss, HK). Still drained.
- Tried firmware verions , 179 , 205, 235, 270
- Deleting 3rd party apps. Still drained.
- Installing Gsam - checking for consuming apps. No apps listed as cause of the drain.
- Installed greenify. Tried as standard, non-rooted with adb permissions, and fully rooted. Still drained.
- Disabling various packages related to 'carrier services', qualcomm and rcs. Still drained.
- Debloated to the point that the phone had no google apps, no Xperia apps and removed tons of other apps, camera bloat, anon data, etc, all removed. Still drained.
- All built in apps replaced with a 3rd party app, including, sms, contacts, email, keyboard. Still drained.
- Installed Linage OS 15.1 Beta 5. Still drained.
- switched from 3G only to LTE only. both drained equally.. though I have worse single with LTE in my area.
I am hoping there is a better solution than throwing the phone away. Because I am pretty much at that point now. I have spent probably well over 120 hours trying to fix this, and I can't. Its at the point where I need to move on to a new device rather than waste more time.... but there are no small devices on the market now, and also no more classic xperia style devices on the market. Sony does not make the executive, classic 'Xperia' style I fell in love with anymore. I don't do round, heavy, huge phones. Very sad.
UPDATE - AUGUST 14
Now running the latest Customized German 270 firmware.
Still draining 20% per night. Check out the screen shots - clear to see I have almost no apps. No process can be seen as a battery hog in both Gsam and BBS. However Gsam screenshot shows evidence of CPU usage.
UPDATE - SEPTEMBER 13 - FOUND THE PROBLEM
Considering almost nobody had my issue, I assumed my phone must be a dud. Late August I bought a second XZ1 compact. The new phone worked for 1 day, and on the second day drained battery at 15% per night idle drain. Previously I had only tested the sim card by switching 3g,4g and disable mobile data, but never actually removing the sim from the phone. Last 2 nights I replaced my old sim with my gf sim of a different carrier. In the morning I had 99% battery remaining. No Drain!
I then downloaded an app these measures signal strength, and turns out where I sleep at night, there is is less reception. Its not noticeable just looking at the standard signal strength on your home screen, you need to check the more detailed strength in decibel millimps /dbm. I can still get good signal in most areas of my house, but the phone is having to use more power to keep the signal good. I can now reproduce the battery drain on demand. If I sleep with the phone near my bed, I get drain. But if I keep the phone in the living room, no drain. I found that connecting to wifi not a factor, since even if you use wifi for data, the phone was still holding open a connection the the cell tower.
This problem took me months, countless hours, and the expense of buying a completely new phone!!! Now I have 2 XZ1 compacts....arg.... but so happy its solved.
The important point is that if testing sim, good signal, or disabling mobile data, changing 3g 4g isn't enough. Your phone is using more power to maintain good signal.
Thank you to everyone who spend time trying to help me, digestive, proflyer, etc. Thank you guys.
At this point, I think it's highly likely you got yourself a lemon. Since you've already rooted the phone, warranty service is out of the question.
It boils down to two options:
1. Pay for a board replacement.
2. Try your luck with a brand new XZ1C. Buy it online so that you'll get the 7 days return perk (some online stores offer 10 days), keep it wrapped in its original packaging, handle with extreme care, and use it normally for a few days before your return window runs out. If you no longer get drains, congrats, and welcome to the club. If not, accept your fate, return it for a full refund, and give up on the XZ1C - understand that you weren't meant for each other and move on.
I had the same issue. Check this thread. Try that and report back.
https://forum.xda-developers.com/xp...ormal-battery-consumption-wifi-t3740495/page3
I know what you feel. I had this too, but mine went away and I only very rarely have this drain. But mine was always on Wifi. With Wifi off = no drain reported... never.
I investigated it for weeks without coming to a conclusion.
If you can, replace the phone with warranty. Worth a try. Right now in my opinion you have a hardware faulty device.
But i would say to wait for android 9. In my opinion it wont take ages to come. It will much likely come this year.

He still has drain even with WIfi Off, so that not the problem.
The only other thing I could suggest is having the battery replaced at a local repair shop. If you got a lemon battery but an otherwise fine phone, that could help.
How about remove your SIM card with wifi on for over night? Do you still experience the drain?

ONE WORK AROUND. If I reboot the phone, then unlock it so "android is starting" screen is complete. Then lock the phone, without doing anything else - The battery does not drain overnight. In light of this, what could be the solution? I know an app sounds logical, but I arlready checking my 3rd party apps, and none of them were the probably, an no battery app has ever listed an app as a drain.
Any technical or Dev person go any idea what that symptom points towards?

This does indeed sound like an app or a service gets stuck in an awkward way. You indicated in your first post that you use better battery stats, do you mind posting screenshots of the top of the summary, kernel wakelocks and partial wakelocks page (showing keeping awake services) as well as the bottom of the cpu states page (showing deep sleep time) "since unplugged" after a few hours of drain?
I have attached corresponding screenshots here for my xz1c (after more than 24 hours unplugged) as a reference (I have play services enabled and syncing both gmail and contacts and so on, no root though).

That doesnt make too much sense. Test it for at least one week before coming to conclusions.
Try this and let me know if it works
I had exactly the same issue
What i did (now magicaly works)
I did not have too many time so what I did was simple and I got a cheap replacement phone in the meantime
It seems to be beyond everything we tried
I conected the phone to the pc and did the fix with xperia companion, then I realized that everything was working as soon as I started to install the apps the problem came back, I installed a launcher (nova) and use it, drained the battery Ăștil reach zero and fully charge it, then everything was working... Back to normal... I don't know how the issue was solved but hope it works for you
Sorry about my bad english xD

The screenshots from BBS look pretty normal, the GSMBattery shots show issues with Google Play Services, so I'm guessing they were taken at different times. But there's nothing jumps out of the stats that looks out of the ordinary. Have you run the phone in safe mode overnight to see if you get the same drain? I think you may just have a duff battery, no one else has reported this sort of power loss before.
$40 down the repair shop to get a new battery is going to be a whole lot cheaper than a new phone.

Thanks didgetsteve. your probably right.... The GSAM and BBS stats were taken right after each other, maybe a gap of 2 mins. Play Services wasnt the issue though, as I tried my phone google free, and it still drained.

I agree with didgesteve, nothing jumps out by just looking at bbs (I am not familiar with gsam, so I cannot comment so much on that).
Before replacing the battery, I would probably make sure that it is not radio/network related. I have noticed that my phone draws significantly different amount of battery (in deep sleep mode) depending on the mobile network. This is mostly independent on whether mobile data is on or off.
Could you turn on airplane mode for an hour or two and verify that it is not the radio chip that is causing your drain? (If that is the cause, I am not sure if you can do anything about it apart from switching carriers or experimenting with 2g/3g/4g settings, but it might be worth knowing)

I also had the drain that Dean has. But mine wasnt so agressive, I mean, some days it was there draining 30% battery over my sleep time (8hrs) and sometime it just behaved normally draining max 3% over sleep time. But still from time to time the drain come back wich is annoying as I cant let my phone with 30% battery left when im going to sleep, afraid the battery will be dead and the alarm wont wacke me up lol.
On my extensive tests, the drain only happened with wifi, but even deactivating all wifi related process (backups, syncs etc) the drain was sometimes there. Wifi wasnt the culprit with Dean, but on my tests: Wifi On = Sometimes big drain , Wifi Off = never drain.
I never managed to find the culprit of this damn drain and Im a software tester. Gsam did not show anything unusual at all. It was like Deans screenshot.
We discussed about this issue a lot here (https://forum.xda-developers.com/xperia-xz1-compact/help/battery-life-bit-odd-t3688342/page8) but till this day we dont know whats triggering it.
Im curious how the phone will behave on this issue with android P.
@ergoen @Didgesteve . Can you guys comment on my 4th screen shot, the one where you can see the CPU usage. Does anything strike you as odd in that pic? TThe CPU util looks high... it is normal?
i dont see nothing odd there

I'm sorry, but I don't think I have the knowledge to judge that. I would expect CPU usage to be low in deep sleep mode, but since the CPU is mostly sleeping, I guess any requested usage will queue up in a way that might look odd, so what you are seeing might be normal (but again, I don't actually know). I also believe that CPU power consumption is mostly related to the frequency state it is in, so deep sleep should mean low consumption (independent on cpu util %).
As I indicated in my previous post, I would sooner blame the radio chip or the battery than the CPU given your BBS screenshots.
mi drain came back today... some days its there and some days its not...

Bro, Samsung is even worse when it comes to battery drain. Check out linus tech tips vid from a few days ago https://www.youtube.com/watch?v=n46s_iF_IV4&t=324s
My wifes side of the family all have Samsungs.... they are totally ****. The OS is bloated, ugly, laggy despite monster specs huge ram, snap 845, and battery nightmares on brand new phones exactly like in Linus's video. And there is a stupid "BIXBY BUTTON" on the phone which is a total nightmare. if your with Samsung, BIXBY will the with you, following you forever.
In other news, I replaced my Taiwan XZ1 compact with an Australian XZ1 Compact, and my drain is gone. I drained 2% last night.
There are so many build differences with the Taiwan and Australian build of the phone. Bigger microphone holes, slightly different proximity sensor design, and the plastic back is a rough matt black/gray in the AU versions, the TW version was a smoother shiny midnight black with a silver sparkle in the sun. The biggest difference was of course the battery drain.

Massive battery drain before and after wipe

Hi. Can someone help me with my problem?
Im facing massive battery drain even after wipe, im only getting around 3/4h SOT. In BBS, 2 alarms are weird Job.delay. And job.deadline. I have wiped my phone, installed last version of rom, after that i have restored my apps. Problem still exist. Next i have installed kirasakura kernel and then frozen every of my apps, and its still there. After night im losing around 10/20% of battery. Im attaching some screens from bbs. Thanks in advance for every help.
i'll try to help as much as i can. install servicely and look at running services. if you see something weird, stop that service.
also, i see you're using bluetooth. that thing drained my battery as bluetooth would stay turned on even when it says it's off. what you can do is turn it on and off and it should stop bluetooth service from running.
in servicely you can disable apps from running in the background. maybe some app is running full throttle even tho you thought you closed it.
another thing you can check is if xmode is running. once i had system turning on xmode on even tho i closed the app that used it.
as you're rooted, check with some kernel manager what cpu governor is turned on. maybe the system is stuck in performance mode.
lastly, you can check your battery capacity. maybe it needs calibration. that could also result in battery drain as it's not charged to the max.
also, android 10 is generaly badly optimised for our phone. it has some good features, but powerwise it's not that efficient.
if nothing works out, i'd suggest returning to latest android 9 and do battery calibration.
Thanks for answer. I have installed servicely but im not see anything suspicious. Xmode is off, governor ist in performance mode. About battery calibration, i dont need extra juice from my battery, i want to lose 1% over night, not 20%.. Probably around July/august everything was fine, my battery last for almost 3 days, now something eating it alive and i dont know what is it. Can i somehow check which app generate this "job" alarms? In BBS its "Android" only..
battery calibration isn't about extra juice, it's about system showing the right percentage. you could lose a lot of battery because it doesn't get charged to its max capacity.
there could also be a problem with the lastest update. when i was seeing a lot of battery drain, i had it because system constantly used location services. check in services if there are any location processes running. also it could be because of network. maybe your phone is constantly switching between 3g and 4g.
you can also check in the kernel manager what is your current battery draw in mAh. if its always over 300mAh, then you have a problem.
look for a wakelocks running in the background and disable and enable some to get them resetted.
Probably u have solved my problem. Even after turning off location, i still have some running services with location in name. I have blocked all of them in servicely and after night i lost 1% of battery. I will check now in later days. Thanks a lot

A reload generally solves nothing and wastes time. It's always best to find the root cause(s) and address them directly otherwise they tend to reoccur.
Viruses (never had to), boot loops (prey it works) and old loads are the only times I reload.

yeah i thought it could be that. it's also worth checking if you have "find my phone" turned on. it's somewhere in the settings. search for device admin apps. if you see any apps turned on as device administrators, turn that off. those could also drain battery
Yep, i have turned off "find my phone" now. Thanks once again. Now i have nearly 8h SoT again. I hope it will be all good now
i'd still do battery calibration if i were you. 8 hours of sot is not that much. i mean, it is if you're playing games all the time
After couple of days, problem is back. No new apps, 3 days was good, 0/1% drain in night, now its again about 15/20%. I will just sell this phone becouse i dont have any more patience...6000mah and my OP3 with half of that value can ez get about 5h sot. Aktually im getting about 3/4h sot and 3h calls. When i have bought this phone i have had about 10 h SOT and 5 h of calls in 3 days of usage. Never again gonna buy phone from asus. Thanks guys for every help
i wouldn't condemn the whole brand because of one phone model.
also try going back to android 9 and check how's the battery drain without any apps installed. then start installing your apps and monitoring if the drain will increase.
i'm currently on android 10 and there is some major problem with battery regulation. raw capacity goes below zero when the percentage is below 10 percent. no wonder the whole system starts stuttering when battery level is below 3%.
