[Q] Android System processes draining battery even when FROZEN? - Verizon Galaxy S 5 Q&A, Help & Troubleshooting

By the end of my battery's lifespan during the day, roughly 70% of battery is drained by Android System and the various processes included in that. So a few days ago, I rooted my S5 and downloaded Titanium Backup, and proceeded to freeze the processes that were draining the most battery (according to Settings and GSam battery monitor. These included SilentLogging, GestureService, AllShareCast Dongle Update, and various others that I deemed unnecessary. I figured this would fix the problem, but much to my surprise, I checked out my stats today and they're all still the biggest battery drainers! And they're supposedly frozen! I'd done a factory reset before to fix this and it didn't do anything, I'm sick of my $500 device lasting me 10 hours of moderate use, because I'm charging my damn phone two or three times during the course of the day. How the hell do I get my battery to at least be REASONABLE?

ok, my phone battery life is messed up. Help please

Hi guys, this is not another rant post about battery life, but i'm starting to become really
frustrating with it, i tried almost all the solutions provided here on the forum but i can't
simply get the **** out of it. This is my story:
I bought the phone as used around 1 month ago (the guy who sold me the phone used it for around 1
month as well). I was quite satisfied about the device, but i noticed almost immediately the damn
poor battery life. With stock battery, my stats are (this is an average of the last 3 times i
used it):
Average duration: 27 hours
Average display usage: 2.5 hours
Average display %: around 45%
Average standby: Cell 30%, phone 15-16, other apps and android core 1-2
This with the following configuration:
3g off
gps off
background data off
bluetooth off
display brightness set to the minimum
no background applications or live wallpapers
No animations
No vibration feedback
No sounds
No widgets
Removed 5 touchwiz panels out of 7
Wi fi on (actually i noticed some small improvements by leaving it off)
The strange thing is, i noticed that the phone drains a LOT of battery while in standby. During
the night (7-8 hrs standby) my phone can drains up to 20% of the battery life. I read on the
forum that a lot of you guys have a battery drain overnight of around 2-3% which is 10 times
lower than mine.
So i thought about 2 possible causes:
1) Software related(processes or applications running in background)
2) Hardware related (battery ****ed up by the previous owner; phone not going in standby correctly)
Regarding the problem 1) i tried almost every solution provided here on the forum. Updated to new roms (JM5 and JM8) installed ultraslim roms, installed battery saving applications and task killers, performed some exotic "fixes" (removed battery stats file, tried to completely drain the battery following some procedures explained here on the forum). Nothing helped. To check case 2) i bought a cameronsino extended battery. Well with this battery i have exactly twice the duration of the stock battery. Last night i charged it to full before going to bed. This morning, when i woke up, the phone drained 10% (!) of the battery in 8 hours. So the stock battery is not the problem. What should i think then? that My phone is ****ed up? is There no chance to obtain a decent battery life? How is possible that a lot of guys have almost twice my battery life with stock battery?
I guess your phone may not be going into the sleep mode correctly ... try using system panel (from the market) and figure out which rogue app is causing the problem. Mine usually drains 4-5% at night.. (jm8 stock + voodoo)...

[Q] sudden drop in battery life

I've got the 16gb nexus 7 (non 3g).
I've had it for less then a year and the battery life had been great. But starting over the last few days the battery is horrible. After a full charge over night my battery was down to 50% today. And that's with hardly any use. I used it for maybe an hour total and at least half of that time was just reading reddit.
I haven't changed any settings recently. This is all stock, no mods, not even rooted.
The battery usage right new says it's been 13 hours, and it's down to 48% and Android os accounts for 27% Followed by screen at 18% and WiFi at 9%. Those are the top 3 showing for battery usage.
Any suggestions as to what's going wrong it how to diagnose be fix it?
Thanks
Either your battery is bad or you have a stray process running somewhere.You might want to factory reset it, possibly even reflash your image.

Would the battery go bad that fast though? In my experience batteries usually gradually get worse. This went from losing a few percent of power to losing half power in the span of a day.
I might try the factory reset - just have to make sure everything is backed up. This tablet isn't rooted so i dont have titanium backup on it.

Doubtful it's the battery... my money is on a rogue app!!!
Hi, merkk...
It's possible, that as the previous poster suggests, some rogue app is 'eating' your battery.
The biggest consumer of power is the screen, so ensure you haven't got it set it maximum brightness... and ensure auto-brightness is enabled in settings.
Another thing you can check, is your WiFi setting... on my Nexus 7, I have 'Keep WiFi on during Sleep' set to 'Never'... it's not a setting that is easily found - it's buried in SETTINGS>>Wi-Fi>>overflow MENU (three dots, top right hand corner)>>ADVANCED>>Keep WiFi on during Sleep.
It also might be worth checking if the SYNCING of your respective accounts (Google, Twitter, etc.), haven't been inadvertently changed. Particularly the SYNCING of your Google account... which by default, SYNCs a lot of stuff and frequently. This will keep WiFi awake, and may cause battery drain. Go to SETTINGS>>ACCOUNTS>>GOOGLE and disable what you don't need to be SYNCed.
-----------------------------------------------------------------------------
It's unfortunate that your Nexus 7 isn't rooted, because there are a couple of excellent diagnostic apps available (GSam Battery Monitor and BetterBatteryStats) which provide more granular and finely detailed battery info/history than the standard Android battery info screen... and are useful for tracking down problematic apps that might be keeping the device unnecessarily awake ('wakelocks', etc.).
However, due to changes in Android 4.4 (KitKat), these apps now require root access to read and report battery stats info.
If your Nexus 7 is running any version of Android BEFORE 4.4 KitKat (and some haven't updated yet), then you don't need root to run these diagnostic apps.
-----------------------------------------------------------------------------
It's sometimes the case, with Android, that there will be occasional peculiarities with battery performance... and in my experience, it's almost always the case, it's due to something the user did... some app or widget installed. I'm currently experiencing similar battery issues on my Samsung Galaxy S3, but having run GSam for a couple of days, I think I have the culprit identified. If I can't eliminate the problem, I'll uninstall the app.
-----------------------------------------------------------------------------
Hope my ruminations are of some use.
Rgrds,
Ged.
Gedblake, thanks for the suggestions. For whatever reason, today it seems to be back to normal. The only thing i did last night was drain the batter to around 10%, turn it off, and let it charge while turned off.
Turned it back on today,used it for about 15 minutes or so playing a game. And now just about 5 hours after turning it on, it's down to 92% which is what I'd normally expect.
I'll try some of your suggestions if the problem re-occurs.
I noticed that my N7 (2012) has been draining quite a bit lately. Watching the battery stats, it seems Google Wallet was eating up some major battery. It was 2nd at 29% with the screen number 1 at 38%.
Not sure what the heck Google Wallet was doing, but I killed it and things seem to have stabilized.
battery drain after update?
For years I've had the same routine. I use my Nexus 7 all day for work, mostly notes. In between I play, (youtube, E-reader, etc). Every night I plug it in to charge and in the morning it's fully charged and ready to go. On Tues, I received the OTA update for 4.4.4 I noticed this morning that after a full night's charge, the battery only reports 50% charge. Is this the beginning of the end? What steps should I take from here? I recently bricked by GS3 so I depend on this thing now more then ever, any help would be sooooo appreciated.

I'd just restart it and let it charge again. I've updated mine a while ago and haven't had any issues.

I'm on a custom 4.4.2 ROM and I have had intermittent draining behavior as well.
Sync is off, location services off, I turn off wifi manually, and I always clear recents before I have my tablet sleep. I have greenify installed. I'm using better battery stats.
My issue seems to be similar, but I am also having battery percentages jump around.
Earlier today it went from 26% to 43% in the middle of me using it. Without charging. It frequently does this, both lesser and greater values reported. I've had my tablet shut down in the 30% range. I've had it shut itself off on 4%. I've had it drain all the way to 0% and then some before shutting down. I've had it turn itself off and when I power it back on the tablet is thinking it is at 25% or more.
I haven't been getting much more than an hour of screen time with my tablet lately. Clean fresh install of my ROM.
But I've never, until the last couple of days, had it go from a small percent to a large percent active during use. I took screenshots. I even started a thread to talk about it but nobody has responded yet.
Has anyone else ran into this behavior? Is it a sign of a soon to be dead battery?
mine got almost 30% drained on idle, airplane mode, screen off for 3 hours (tested on stock rom 4.4.3. GApps + Swiftkey + BBM + Facebook only)
my nexus 7 never lasted a day, only half a day max.
trying GSam app, hope it helps in knowing what's eating up batteries.

S4 major battery drain

Hi guys so I have a s4 i337m running Android 5.0.2 and recently I have been getting extreme battery drain. It draims around 3% an hour when the screen is off and seems to be awake more than half the time! I can get may even 2 hours screen on time even with my 3000 mah zero lemon battery. I have factory reset twice and even reinstalled the rom and it if anything it's gotten worse. Any ideas.? I do think want to downgrade to kit kat unless if have to.
Not enough information from you to allow anyone to help. Install an app like Better Battery Stats, run it for a day, then post a log so we can try and help.
I have been using gsam battery monitor for a couple of days and the android settings as well. I don't now how to put pictures in this thread but android is and system are at the top. Around 35% screen 20% android os, 15% android system 10% other apps and the rest unaccounted for. In GSAM I get around 70% app usage with both android is and system taking around half that. In the system settings it also shows that I have severe wakelock. I was in an area with no service at the but that is not the problem. I am on wifi 90% of the time. And almost always have a good cellular connection when I'm not.

Battery goes insane

We all know the battery was perfect with M, we all know that since N battery drains way faster, but I've gotten used to that.. Instead of 5 SOT I got 3.5. Ok.
But now.. I hardly go past 2. Battery drains really fast, it's not even stable. Doze doesn't seem to work anymore, percentage drops each minute and a half, and now.. phone shuts down at 6% all the time. What should I do?
I'm a stock user.

You could install GSAM and see if it's an app causing the issue. You can also try turning bluetooth off completely for a day or two to see if that's a cause.
Worse case, you can do a full factory image re-flash. In my past experiences, most of the time, updating OS major versions never sat to well with my phone. I personally do a full factory flash-all after every major update.

I have GSAM but since N it doesn't show stats for specific apps but only combined. As for Bluetooth, it's never on.

Well that narrows it a little more than.
Actually, with a recent update, you can see now.
If you go to Enable More Stats, it will give you directions. I believe you need a file explorer, move one file to another location, and rename that file.
Software fault. The battery doesn't really charge fully, I've noticed that when my phone froze (literally) and it was on on 50%. I warm it up, says 1%.
After that my battery life is exactly half, which means that 1% is actually my 50% but the phone sees it as empty.
Check battery capacity with accubattery. Not completely accurate but it does give you a ballpark range. If the current capacity is way less than the specified spec, then you have a degraded battery
I agree with the Accubattery approach (or similar app) to measure the battery capacity. Several ppl have experienced degraded batteries.

I've done a factory reset, Accubattery shows 3022 out of 3450 mAh and 88% of battery health. Do I need to replace the battery?

Not unless you can get Huawei or Google to do it for free. I haven't seen any new genuine oem replacement batteries. They are either used or fakes that don't work right. Some don't even have a temp sensor. Accubattery shows 2876mAh for me and I get 4.5 to 5 hours sot on 6.0.1. Same as I ever got. After installing 7.1.1 with full wipe from factory image, same settings, same apps, same signal, same usage, I get 3-3.5 sot. On nougat my phone would intermittent turn off under 15%. Hasn't happened once since I rolled back to marshmallow 2 weeks ago. Either some people (like me) are using certain apps that consume battery without it showing on gsam and better battery stats, or nougat just uses more battery when the screen is on. I believe the latter.

I wouldn't think so based on that snapshot. I'd keep running the capacity test (documentation states accuracy is improved with time) and start looking very closely at individual services and apps for anomalies. If rooting is an option for you, wakelock and battery statistic tools are better able to return more accurate data than non-root apps. Absent any rogue apps or services, monitoring the capacity will give you a trend and likely answer your question about replacing the battery.

Ok, good to know.
Can you please follow this order of events?
1. The battery was as I've noted at the beginning of the post, drains fast and shuts down at 6%
2. I've had a factory reset.
3. I turned on the phone, clean and wiped, at 35%. It took me 1:29 hours to get from 35% to 7% [which is great!] but then at 6% it shut down again.
4. I turned it on right after, it showed 1%. It lasted for another 10 minutes of usage.
5. I charged it to 100%.
6. Then, when the screen is off, battery loses 2% per hour, and when I use it, it loses 1% every 3-4 minutes [which is great], BUT - sometimes it loses 2% at a time, say 80 to 78 and so on. I still don't know if the phone is gonna shut down at 6% or if it was already fixed.
Does that seem normal?

It doesn't seem normal to me. Neither the 6% shut down nor the increased battery drain. As I said, I had both issues to some degree, early shutdown, and much less screen on time. Since a switch to 6.0.1 fixed both issues I am lead to believe they are software problems, not hardware. Google responded on reddit that they are looking into the early shutdown issue about 10 days ago. Then there is also the sudden influx of bootloops of death after Nougat. My advice is to use Marshmallow until things become more stable.
You could go into accounts-Google and see if there are any syncing errors.. Facebook and Facebook Messenger are both known to cause big battery drains on Nougat. Gas Buddy used to be a problem as well but not sure if it still is. As another person suggested doing a full flash-all.bat clean install might fix your problem. Some people just go back to Marshmallow,

Unusual (erratic) battery percent after battery removal?

Hi there.
I got this 2nd hand Note 3 (N9005) last week, and I'm testing battery life in different conditions with the original top update (5.0), before I flash a custom ROM and use it as my main phone.
System says battery is in good condition, and it has a fairly good standby time, but it drains quite fast (about 1% per minute) when active / SOT. GS monitor says I'm averaging 1h46m SOT, which I know is not good, and understandable since I guess this is the original battery.
Now the weird thing: I had about 13% battery when I turned it off. I removed the battery (I needed to take out the SIM card, I don't think this is related) but when I put the battery again in and turned it on, I had 35%!
I spent all of that until it has below 3%, it sounded the alarm and completely dimmed the screen and so, then I removed again the battery (checked also the contacts, nothing dirty on the battery or phone btw).
When I put again the battery, I got 18% power left. Now it's gone and I am afraid to play this game anymore - I'll just give it a full charge.
Does anyone experienced similar behavior? I wonder if it's a calibration problem, or a known symptom for old batteries.
As a side note, I had a Note 3 Neo Duos last year and the battery was bad. It used to discharge almost instantly from 30% to zero and turned off the phone. However I remember that I could remove and put again the battery for some extra life, just the same. I'm more or less terrified by this lol.
(The Neo Duos, N7502, was stuck at 4.3 without any development. I'm glad I was able to get this N9005 now).
I'm attaching a GS mon. screenshot showing usage so far, and the system Battery Use that shows the two points when I removed the battery.
Difficult to follow your post.
Suggest as first step Wipe Battery stats.bin.
Or from play store battery calibration app to wipe battery stats.
This will not calibrate battery just reset battery stats.
