hi,
today i tried to "stress test" my g1's battery. everything on, max display brightness, nearly the whole time turned on, running a few apps etc.
and now after 6h 10m it is at 8%. the surprising part of this is that cell standby drains 27% battery life. the second highest consumer is no less surprising, phone idle, 18%. then wifi, display and android os with about 15%.
this seems wrong somehow. is it normal that cell standby consumes so much battery?
i am running cm5.0.7 test1 which i remember to have an issue with battery life. somewhere i read that i only had to turn off the percentage-counter in the status bar (which i did). is the high cell standby consumption related to that? is there maybe another radio version Oo? (using: 2_22_23_02)

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)...
Does setting an alarm overnight cause a lot of battery drain??? plus i use "hide my text" app, also known as "invisible texts" app. Is that the reason for this battery drain even when the wifi is off and with 10 texts n no calls, my phone's battery goes down by 40% in 8hours....is that normal?? I have nexus s 9023.
In the "battery use" option it shows that the phone display is consuming 33%, I have auto-brightness ON, and 30seconds screen On time. and not using a live wallpaper.
Cell standby shows 10% battery usage. Auto n background sync is also off.
Currently it shows 7hours 1min 14s on84% battery.
the current android version is 2.3.6
also when i was using a task killer, it showed that new apps started up by themselves even when the wifi was off, every time i opened the app killer it would show a list of working app =S then i thought that the task killer might be causing the battery drain so i uninstalled it.
kindlyyy HELPPPP!!!
Better Battery Stats, search for the .apk in xda. It will likely reveal your mystery wakelock.
So, after removing cell idle from the battery drain equation and disabling as many system apps as I could get away with, I notice system idle is draining the vast majority of power. If I barely use the nook, it only lasts for about 3 days. 97% of the battery drain is from "system idle" and 3% is from screen. I noticed that system idle drains as much power per minute about as the screen does. How can I diagnose what is sucking the power when idle? Under ideal circumstances, overnight drain should only take 1-3%, but for me it drains about 15% on idle.

Don´t know if this helps but since I upgraded the official firmware to 1.2.0 on my Nook Glowlight, I have the same issues. My nook not being rooted or in any way changed, I suppose they have included some bulls*t in their original fw. So if you are using it as a base for your rooted image, it might explain the battery draining.
They have pretty quickly came up with a version 1.2.1, maybe they´ve realised and resolved the issue, so I will try this as soon as my nook recovered from the latest drain. If that doesn´t help, I´ll go back to 1.1.5, and if that fails, I´ll visit them and kick some butt for ruining my perfectly well working reader. Thank you so much, B&N!

I've got the same problem on 1.2.0. I've updated to 1.2.1 and done factory reset. After that battery drain wanished.
BTW I've never rooted.
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
BASEBAND : MPSS.TH.2.0.1.c3-00045-M8996FAAAANAZM-1
KERNEL : 3.18.31
BUILD NUMBER : NRD90M
SOFTWARE VERSION : V10g-AME-XX
MODEL NUMBER : LG-H990ds
my actions are as follows :
phone is factory reseted. No third party apps is installed. [especially social media apps.]
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.
