Unusual (erratic) battery percent after battery removal? - Galaxy Note 3 Q&A, Help & Troubleshooting

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.

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] bad battery life on my hero

Hey guys, i have a problem concerning the battery life of my HTC Hero with FroydVillain 1.7.3 (Android v2.2.1)
In the last couple of days my battery goes down by 10-12% per hour without even touching the phone. I tried factory reset, wiped sd card and reflashed, flashed CM7 but still the battery issue didn't go away.
I charge it 100% before i go to bed at 11.30 and when i wake up at 7 the phone is completely powered off..
The thing that consumes my battery is the process "Android OS". I read about it on the internet, but all threads were SGS2..
The strange thing is that it's CPU usage time according to the battery stats is 1h 21m after 3 hours of sleep.. Is this normal??
I have everything turned off - wifi, gps, mobile data, auto sync, background sync and still the drain continues.
Has anyone had this kind of issues and possibly a solution?
Or should i buy a new battery?

I have also been experiencing battery issues with Froyd lately, but not to the same degree as you are. My solution was to wipe and install another 2.2.1 based ROM. This new ROM is acting normally in terms of battery life.
With Froyd, my battery was acting "weird" in terms of overall battery life. Once I got about 3 good discharge / charge cycles in a row things seemed to improve.
Another thing to consider is did you recently install any new apps? Some apps don't play nice and cause the phone to not enter sleep state OR cause excess CPU usage.
Some people might say "wipe battery stats" but some Google Engineer / Developer has recently dispelled that myth... https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
Good luck!
It's not from any app. Last night i wiped my sd card, wiped everything from recovery and flashed Froyd. I used it all day without installing anything besided battery graph to monitor my battery usage. it's something from the OS itself i guess..
The funny thing is that it seems that in the past two hours the drain has disappeared and now the battery is reducing by ~1% per hour and i haven't done anything during that time, except 2 calls under a minute each and 1 sms.
How old is ur battery? Did you consider that it might be physically related? Not because of the processes or so?
One more thing I noticed - if I charge by ac outlet, it charges faster, and lasts longer, if I charge by computer usb port, it charges really slowly and battery drains way faster... I don't know about battery life, maybe from ac outlet it dies faster, but 2 years of using it and still 1.5 day of normal use...
Thanks for the replies guys! I found the problem, it was my radio.
I flashed the latest radio and now my hero's battery life is better than before!

Looks like you have a battery problem. OS does not really kill batteries, you can see more or less the same performance if there are no background apps eating your power.
Check these batteries for your Hero. These are top quality and many users vouch for them.

@saj222 i'm now running the same radio as the one in your signature. before that i was with 09.05 or sth like that..
@porcupineli my hero is second hand with about a year of usage before me. i have it for about 2 months now. Since the phone costed me $90 i don't think i can pay $70 for a battery.. I was thinking of buying this one

Battery drain!

I don't know what the hell is going on with my Note 4 (SM-N910F), but my battery is draining a lot faster then it ever has. A couple months ago i rooted my phablet, tried out two or three different custom ROMS (Omega was one of them), but my Note 4 got so hot it got into a bootloop as soon as I entered my PIN. I reflashed stock ROM and it was back to normal again, but lately it started to warn me for low battery (the 5% warning) and turn off itself in seconds even when i had 20-30% battery left. This didn't happen every day, but it was annoying. So i re-rooted and installed CM 12.1 thinking it was the 5.0.1 and 5.1.1 stock updates. The first night I charged it all night but only got 83% battery when I woke up 9-10h later. Today when I was scrolling FB with 35% battery left, the phone warned me about low battery and dropped to 5%. Is it possible that the battery drain is because the overheating could have caused some damage to the phone/battery? I tried calibrating the battery two times, did everything I could find on the net, but nothing helped. I would like to know if there could be something more than the battery that could cause this because I don't want to buy another one for nothing.
you could try to re-calibrate your battery, you can find a app for that on playstore.
is your phone still getting hot when your battery drain is high?
you could post an image of your battery stats from settings or better battery stats so we can see, why it's empty so fast
I already tried that two times, it did make the battery last a bit longer but the 35%-5% problem is still there. I'm new to XDA so I can't upload the screenshot but I can't see any app or activity that's draining the battery. I've done everything I could find in the forums (lower screen brightnes, turned off auto wake, even downloaded kernel adiutor and changed some settings a guy posted) but nothing has changed.. I'm just wondering if it's the battery that's the problem or something else so I don't fo out and give out money for a new battery if it won't help..
And yes, my phone is still getting hot when the battery is draining fast.. I do have an insurance that I could use but if it's just the battery then I can buy a new one. I forgot to mention that the phone gets pretty hot when I charge it, somewhere above the battery connectors. Eather that or the micro-USB connector, or even both at the same time.. The cable has turned yellow just under the connector so I don't know if it could be the charget that messed it up. This started before I even flashed a custom ROM.
Well I couldn't take it anymore and decided to downgrade my phone back to 4.4.4 which it came with. 9h on battery, Spotify was playing for 3h, played a little on Snes emulator, facebook, chrome, and I still jave 56% battery left. Seems to me that I was one of them who got the f*cked update for 5.0.1 and 5.1.1.. my phone is back to normal with speed, battery usage and heat. I'll let the battery drain completely today and see if it will turn off at 25-5% like it used to. The worst thing is that a game I used to play dosn't work on 4.4.4.. but it's still worth it!

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
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.

Battery drain Fossil gen5

Hi all,
Since a few days I have a huge battery drain om my Fossil gen5. It never was the best battery, but it lasted from 6am till 9-10pm before it went in battery saving mode (without sport exercise)
Now it's already in batt saving mode after 10 hours .
Everything is "on" except WiFi, nfc and OK google detection. The same settings and apps as a month ago.
Are there any tricks/mods/custom roms to extend battery life without compromises in functionality?
I already did a reinstall, but unfortunately it didn't affect the battery life.
Hope someone can help me

Other than turning off things like Location (as you already have Wifi and NFC off), not too much else than uninstalling apps you don't need, and turning off Notifications on most of your apps except the main essentials you want.
Turn off Always On displays, or the Tilt/Tap to Wake (they do consume more battery and it's just as easy to hit the main crown).
Only turn on Location/etc when you need them rather than on all the time.
Also the little battery inside, if you've been using it from 0% charged to 100% the whole time, instead of keeping in in 20% ~ 80% (ie: not charging more than 80% or so), the battery itself will deteriorate after a while. Keeping it between 20% and 80% typically keeps most Li-Ion/Po batteries healthy longer. (kind of why wireless ear buds can't hold a charge anymore after 2 or 3 years).
