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] Recalculate battery life after getting big battery

I got my hands on the zerolemon 7500mah battery for my S4 about a month and a half ago and it is amazing.
With normal use (multiple e-mail push accounts, location tracking, wi-fi enabled etc) I get about 15% battery drop a day.
After a full charge, battery apps tell me "17-20 hours available."
Somehow the battery logic for android phones seems a bit off, it seems to be more a guestimate towards the current power use then the actual recorded battery run time.
Is there anything that can actually profile a battery ? Record the power use and battery voltage levels and give a more accurate picture over time ?
I *thought* android actually did this but apparently not, or its been because I'm only on my 4th charge since getting the battery but i'd like some confirmation if that's the case
I love this battery, this kind of battery life should be standard, only Android can't really deal with it properly yet .. the 15% battery alarm especially can be a pain: 'what do you mean battery low, its at 15% that's a full 24 hours!' and it still puts the phone in power saving mode.

[Q] Fluctuating Battery Usage Overnight - Why?

I have a new Samsung S4. Trying to learn how best to configure it to minimise battery usage and to ensure I don't install apps that eat battery. There's nothing wrong with it, battery usage is fine, just trying to get the best out of it; whilst keeping as much functionality as possible without having to constantly turn things on and off. I'm trying to avoid rooting it.
As a starting point, I'm checking usage overnight, when blocking mode and power saving are on, with wi-fi and data off; but with the alarm clock set.
I have an i-onik 7.85" tablet on Android 4.2.2 - with a deep sleep battery saver app set to slumberer ("always deep sleep when screen off") it only uses about 2% of battery overnight - the battery currently holds about 3600 mAh - so that 3% equates to 108mAh.
First time I tested my Samsung S4 (the european LTE version 9505), (actually I think I had wifi, data, location setting turned on and power saving turned off), it used 4% battery overnight. Not bad, 4% of 2600 mAh is 104 mAh. Still I thought I might do better. I tried the deep sleep app on slumberer but inexplicably the usage then jumped to 12% (whereas it at least halves battery usage on my tablet). I've since un-installed deep sleep battery saver and started turning off wi-fi, data, and turning on power saving - so I'd expect it to use 4% or less battery overnight.
The actual battery usage instead increased to around 9% to 12% - although the settings used might have varied.
Three nights ago I made sure that all apps were closed, and everything turned off as above - battery usage overnight was still 9%. I used WakeLock Detector and found that a Morrisons App was causing wakelocks. I uninstalled that, and the next night the battery usages was down to 6% with much fewer wakelocks. Still not as good as before though.
I then found there were wakelocks due hotmail and gmail sync - hotmail I changed from push sync to sync every 4 hours, gmail I changed from hourly sync to manual sync and I also turned off master sync. I also turned off location setting. That cleared the wakelocks for these apps, but battery usage last night had increased to 9%.
So, despite the same settings and less wakelocks (and it was in deep sleep all night except for 16 minutes), battery usage increased from 6% to 9% - still no where near the 4% I had at the start despite making various changes that should reduce battery consumption.
The only significant wakelocks last night were:
com.domobile.applock (via alarmManager) awake 35s giving 992 cpu wakelocks
com.google.android.google (google app) 7 wakeups
Can anyone think of any cause for increased battery usage from 6% to 9% despite more time in deepsleep, less wakelocks (other than the 2 above but there were many more wakelocks the night before lasting several minutes) and location setting turned off. I wonder about starting again from a factory reset ... NB every night before going to bed I've rebooted the phone, and charged it to between 90% and 96% and it's been tested over the same period of time. Is it normal for battery usage when the phone is sleeping to vary so much?

Charging the battery inconsistently might lower the battery life. And letting it discharge to much does the same. I generally avoid letting it go under 50% and unplugging it before 100%.
I don't know what causes your issues, but if you want full control over your phone, you will have to root.
I also had 2% drain over night at some point, but now I have 4%. But this may also be rom related.

Thanks. I'm on stock ROM. I have rooted other devices but then find some apps don't work, and of course I want to maintain my warranty.
Each day my battery is generally dropping to about 30% at which point I charge it up to between 90% and 95% before turning turning most things off ready for bed.
At some point I may leave it plugged in overnight instead - is that a bad thing?
What do you mean by charging inconsistently? Sometimes my battery may be around 50% though more often around 30% when I start it charging.

By charging inconsistently I mean exactly what you said. You charge between 90 and 95% generally, instead of leaving it to charge 100%.
Somebody said that if you live in the EU you will not lose your consumer rights. I guess that includes the right to have your phone repaired because it is in warranty. Other people have reported that the phone service accepted and repaired their phone even though it had knox flag 0x1.
There isn't much you can do on stock unrooted roms in order to reduce battery consumption.
You battery drain is probably caused by weak signal strength. Having bad signal uses more battery. The screen and the phone radio use the most power on the phone. If you put our phone in airplane mode there should be almost no battery loss. If everything is turned off.
On my old device I used to put in airplane mode during the night. I had 0% drain over night in airplane mode.

Thanks - that's a good point about signal - my mobile signal and wi-fi signal does seem to vary, so that could contribute to fluctuating battery usage. I decided to test that by using airplane mode and have started charging to 100% on your advice. Unfortunately when trying to dismiss the prompt to upgrade to lollipop, I accidentally started the upgrade, with no way to cancel it. (For me, lollipop really seems a downgrade, I've lost a lot of functionality I used all the time in KitKat).
The bad news it that on lollipop overnight last night, despite using power saving mode and airplane mode, and basically everything else off including sync, it lost 7% of battery.
So I decided to do a factory reset, thinking it would go back to KitKat - but it didn't - it stayed on lollipop. It did give me the option to choose which extra apps to install (including some Samsung ones) - I declined to install any extra apps, and also turned off automatic app updates - I then turned off sync, backup and anything else that I thought might eat battery - leaving the phone with the most basic set up possible. I've not since installed any apps except Talk2Go.
The good news it that since the "factory reset" to lollipop, I've tested it for two periods of 4.5 hours on airplane mode, everything off, and I did not turn on power saving mode. The battery lost less than 1% - in fact for my last test it stayed at 100%. So either the reset fixed battery loss on lollipop, or the power saving mode was actually causing battery loss!
I'll investigate that and report back for the benefit of other users. I'll then gradually update my settings and see what, if anything causes battery usage to increase when on airplane mode. Of course it's also possible that battery usage might increase without changing anything, as per some reports from those upgraded to Lollipop - if so I'll report on that - and confirm if a reset seems fixes it.
Lollipop is supposed to have a battery saver mode - but it seems to be missing in the stock OTA update to S4 - does anyone know how to use this mode? It sounds better than Samsung's own power saving mode (especially since that might actually be causing battery drain rather than saving battery!)

Samsung probably replaced the stock lollipop battery saver with their own battery saver.
You could return to kitkat by flashing via Odin. Doing so will not give you knox status 0x1 and you don't even need root.
On second thought, you have the new bootloader so you probably won't be able to do it without tripping knox..
From what I saw, battery saver changes only the minimum screen brightness to a lower value than normal and it changes the CPU governor to a more battery friendly one.
This is what I observed on the GPE rom battery saver mode.

Testing continues - for the first few nights battery drain was less than 2% on airplane mode, but it wasn't repeated last night. It drained 9% with exactly the same settings (ie everything off except the alarm clock, no foreground processes running and airplane mode on).
I've installed a few apps - one from TalkTalk, one from Three Mobile, a terminal emulator and wakelocks detector. So have now uinstalled the first 2 to see if they are causing the drain - BUT I suspect it's a bug in this release of Android Lollipop.

Many people have problems with the stock lollipop. Samsung messed up.
It might also be the battery. I have my phone since november. My battery used to drain 2% over night. Now it drains 4% over night. Basically it drains very fast to 96%, from there it drains normaly, depending on the usage. This happens on every rom I tried and with even the most battery oriented settings.

You seem to be using applock. If you don't need it you can delete it and get rid of a few wakelocks.

LG V20 Overnight Drain

Hello,
So I've had the V20 since it first came out and I'm loving it. With the stock battery, I'd charge it every night and not notice many issues. Noticed a respectable 3-4 hours of SOT, which is decent but not spectacular. Then i got the Zerolemon 10,000mAh extended battery for it and I still feel like the phone doesn't have the battery life it should. With the extended battery in, I would sometimes leave it unplugged overnight and lose 15-18% (which, in a 3x battery, correlates to almost 50% of a stock battery) in just one night. So i'm wondering, any apps/servies that just guzzle battery overnight? Any info is a help, thanks!

Good possibility that the new battery you have may be junk.
But you'll have to pop the stock battery in and do battery usage comparisons between the two.

Have you calibrated the Zero Lemon battery? Run it all the way down until it turns off the phone. Pull the battery and then put it back in turn the phone back on to make sure the battery is drained all the way.
Then recharge it without disturbing it. Recommend doing this overnight.
Also make sure you aren't switching batteries once you've got the lemon calibrated otherwise your battery gauge won't read accurately.

Yeah i might have to, i've been trying to avoid that. I honestly think that it's the phone not the battery, because when i leave it alone overnight it loses like 12-16%. Losing that even off a stock battery is ridiculous so i figured it was something with the phone that caused it to run all night without dozing. i read up on some threads about wakelocks after installing GSam and seeing that the phone is held awake quite a lot (as i type this, i'm sitting on 72%, 13h16m of usage, 3h5m SOT, and 4h28m held awake. So i honestly think it's the phone, but then again if i do drain it down then do a battery pull and it jumps up to 30-40%, then i'll know it was the battery

Also, would you recommend once the phone shuts off plugging it in and leaving it off, or turning it back on once i plug it in?

Don't think its the battery, it's highly likely the ROM you're using. I had terrible life after the last update.

I'm running bone stock on everything, no root

Update: been getting significantly better battery life after doing two things:
1. Turned off Bluetooth location scanning (I already had WiFi scanning turned off).
2. Using my phone without WiFi on (on the chance that it might be the WiFi causing wakelocks, which is something I researched a bit with the help of GSam. Wifioffdelayifnotused was the suspected culprit).
I'm not sure which one could be the bigger factor, but I'm going to leave my phone unplugged overnight with WiFi off, then after tomorrow night when i charge it fully again I'm going to see how much battery life I get with WiFi on (this way I should be able to determine if it was the Bluetooth scanning, or the WiFi.)
Any input would be appreciated. Thanks!

Had a zerolemon on my Galaxy S4 and while it was a great battery that added a lot of additional life, I never felt I got enough extra life that corresponded to the amount of mAh that the zerolemon brought. Though it wasn't anything like what you are describing. Just never felt like I got 3x the battery life even though it was like 3x the mAh amount but maybe that's just because I don't understand the whole science behind the mAh ratings on batteries.

Update part 2: turning off the Bluetooth scanning and Wifi (only yesterday, had wifi on today) has resulted in much better battery life so far. Oddly enough, early on it seemed a lot better, on pace for almost 15 hours SOT. I'm at 18% now and almost at 10, but still pretty good and better than what I was getting. I'm chalking it up to the Bluetooth scanning since I use an Android wear watch that I leave always connected. I'll do another full drain tomorrow after charging it tonight, this time leaving wifi on to see how much of a difference the Bluetooth scanning makes (3rd pic is early on when I was on pace for 15h SOT; left phone unplugged last night and stayed at 64% all night. So my 12-18% overnight drain (40-ish% on stock battery) problem is cured )

hi
my v20 phone battery draining was about 1% per hour before (about 7% totally ) and recently increased to 2% during sleeping time overnight. (draining 15% overnight in sleeping state) .this situation's screenshot is attached and named : Screenshot_2018_01_21_07_05_15.
it seems that during day either performance off battery is decreased.(about 5h with wifi and screen on usage)
Fast charging while second screen is On , is slower than when it is off therefore when second screen is Off , fast charging goes better . exactly , first 30 mins fast charging makes about 40% battery charge(instead of 50%) and after 60 min leads to 85% and full charging taking place after about 100 min instead of 80 mins.
another important thing is that sometimes shades have been seen on the LCD that many users have complained about it.
phone information is :
Android security patch level: September 1, 2017

battery calibration steps for not rooted phones is taken place.(turning off the phone and charging several times repeatedly).
testing battery drain in safe mode in done and didn't change results
turn off location services and location scanning for WiFi and Bluetooth scanning
turn off WiFi being On during screen is Off.
turn off auto sync, NFC, GPS etc.
not using auto brightness.
not using comfort view .
turn off location services and location scanning for WiFi and Bluetooth scanning
second screen is off during test overnight. (either with second screen is ON with faced down to lower brightness in other day test [this situation's screenshot is attached and named : Screenshot_2018_01_21_07_49_27] )
phone is in Air Plane Mode and all data services is off.
system apps like Google services and Play and Assistance is limited by permissions.
following are some advanced battery drain overnight figures of my phone for more analyzing.
any help with this issue is appreciated.

Battery Drops to 81%, Only 3% Usage Detected

Hi everyone,
I performed a Factory Reset on my Samsung Galaxy S7 Edge as all of a sudden I was experiencing poor battery performance. Since the Factory Reset, I now only have the device's default apps installed, with the exception of me installing WhatsApp!
The features turn on are: WiFi, Location, Bluetooth, Mobile Data, Sync, NFC and Always On Display (Night Clock). This has always been the case since day one and I don't really want to start having to disable features as that becomes a nuisance.
Just before going to sleep, I charged my device to 100% and then unplugged it. On checking it this morning, the phone had been on battery for 7 hours 53 minutes (totally unused during this time) and it reports the following: Cell Standby at 2% (53 mAh) and Device Idle at 1% (41 mAh) and that's it.
For the first year, the phone would only drop by say... 3-5% for the whole night (with all my fancy apps installed!)
Why would the performance drop so significantly? How can I fix this? Could the Android OS be doing something in the background that it actually isn't aware of and is eating up my battery?
Any comments and tips would be greatly appreciated.
Kind regards,
X22

Welcome to my world...I have the same issue with my phone from the start. Could never understand how other people can get great battery life and I can't. When not using my phone, I loose 3-5 % per hour, more if I use it. My phone never goes to sleep/deep sleep. I tried all combinations to save battery life, but to no avail. I took my phone to Samsung as my display developed grey lines a month ago. I got my phone back and they informed me as part of their service I got a new battery free of charge. With the new battery I get 2% drop per hour, when not using the phone, still no deep sleep etc. We did have an update about 2 months ago and since then the battery life is a bit better when using the phone, it's not draining as quickly, but deep sleep is a big no no when not using the phone...

Hi @termdj
When I first got the phone it was absolutely solid. If you charged it before sleep, you could wake up the next morning and the phone was at a solid 90+% (easily!).
Now with everything turned off (WiFi, Location, Bluetooth, Sync and NFC) the battery is just not performing and loses 20% during the night.
However, I feel it may not necessarily be the battery, but an Android OTA Update which could be causing this. It's only been a short period of time since I noticed it and I haven't noticed a gradual decrease in performance.
Just hoping that some wizard says "you need to do X, Y and Z and all will be sorted"... here's hoping!

Look around on XDA and try some of the suggested battery saving tips. I tried some of them, but with a lot of them it's mostly turning of key functions/features....That's not why I bought the phone, so I use the relevant functions. I have made piece that my battery life isn't wow. I think that something is keeping your phone awake, preventing deep sleep, just as in my case...

I also have the same problem since updating to Nougat
