I know I posted something on this awhile back, but now I need some advice. On my LS970, the battery dies really fast, and it will shut down when at 5-8% battery left. It also tends to loose battery even when plugged in. And I've tested that on multiple sockets. Should I un-root it then send it into LG?

Man, I hate starting new threads! I did a simple search and couldn't find this problem anywhere else, so here goes:
Earlier in 2009 I bought an extended 2400mAh battery for my Kaiser (8925). Everything is working just fine, except that I noticed that the phone doesn't seem to notice that the battery life is much better for this new battery.
What I mean is: after a few hours of usage, the battery level drops at a normal rate.
Once the phone tells me the battery is almost dead (and sometimes the phone will shut off if I ignore this), I can shut down the phone, remove the battery, wait a few seconds and then replace it and boot back up the phone.
At this point, the phone will usually tell me that the battery is at 33% to 36% charged. Notice that I did not charge the battery, I just removed it and put it back in.
When I first got the battery, I cycled it completely three times in the phone, removing it twice and replacing it to ensure that the battery was completely drained before charging it to 100%. (Yes, I know that is only recommended for metal-hydrates, but I feel better doing that anyway).
On the top-end, it usually takes about two hours to charge the phone from 30% to 99% via a standard USB2.0 connector.
However, the phone will report that the battery is not fully charged for nearly an hour after reaching 99%.
I know what you are probably thinking; Why is this guy complaining about his battery performing better than his phone reports?
Well, it IS kind of annoying. I would like the phone to properly report the remaining percentage for my own benefit. I really hate having to guess at how much time I have left before I need to drop it off at a computer or wall outlet while I find something else to play with for three or four hours.
So... Does anyone know how I can convince my phone that the battery is pretty awesome and to start reporting the actual battery life?
Something I've discovered recently, and I am not sure I can explain it properly, but here goes...
I am running SRF 1.1.1, I don't believe this is the cause of the problem, but probably something that should be stated.
So running SRF1.1.1, I usually get wonderful battery life. I typically use an external charger and swap out batteries when they get to around 10-15%. This has worked well for me.. For the past few days I got lazy, and just plugged my phone in and left it on my desk to charge, no problem. When the battery is fully charged and I unplug it from the charger, I noticed it was rapidly draining.... I am aware that often when charging via the phone the battery immediately drops to 96% when removed from the charger. So this is normal, but I've noticed that after unplugging from the charger I lose about 10% per hour, when normally it may be 1-2% depending on usage.
To remedy this problem, rebooting seems to fix this issue. I have also had success with the airplane mode toogle. I don't see any odd usages showing up in spare parts, but is there any other way I can test this theory?
Thanks!!
Edit: Wanted to add, that this only seems to happen when using the charger cable with the phone. Swapping batteries does not seem to produce this issue. It is only when the phone is removed from the charger.
I haven't calibrated by battery lately and thats exactly what mine does too, I would stick to the external charger because our phones charge excruciatingly slow unless off. Try calibrating by charging to full while on then turn it off and let it charge more and repeat that a couple times then boot into cwm go to advanced and clear batt stats
Is there an advantage to calibrating a battery if it is not being charged in the phone?
This is the TWS bug mixed with no battery calibration.

similar to what i have been experiencing. i enjoyed great battery life with srf 1.1.0. have a 3500mAh battery that i used to get about 48 hours out of, but now it is averaging around 25-30. i do not have anything but the stock battery to swap with, so i do put it on the charger nightly now. i was planning to recalibrate the battery tonight to see if that cleared things up.
what would be a way to fix the tws bug?
I have noticed this too. It seems to srf seems to not like my extended battery. I am lucky I get a day out of it. I some times will plug it into one of my work computers just to bring the charge up a little and it starts flashing red and discharging this is only on my extended battery not the 2 stock ones I have. I have even tried different kernals to see if that was issue it isn't.
Sent from my lean mean drunken machine useing XDA Premium and a 12 pack of Sam Lager
in looking at battery usage in >settings>about phone>battery use>cell standby i see usually 0-5% tws.
one thing i have noticed, though have not tested is that the screen appears brighter, even at the minimum setting than what i remember from srf 1.1.0
When I swap the battery in my note 2, it won't power on until I plug it in for a minute even if the battery is charged. Any ideas?
Edit: some more info: I was having bad battery drain on CM10, installed battery doctor. I thought I'd try a new battery as well for the battery drain and started noticing that it wouldn't power on after changing the battery. I formatted, refreshed and installed slimrom 4.3. It looks like I'm getting better battery life, but I have basically nothing installed. I'm still not able to replace the battery without a power cable to "jump start" it. Its almost like the phone doesn't even detect the battery until I plug in a cable.

Update: I don't have any better battery life with slimrom. I'm loosing about 8-9% an hour in standby. About 5% an hour with the phone powered completely off. I have 3 different batteries that all hold charge when out of the phone.
Are you using one of those crappy GOLD Chinese batteries? That might be your problem, don't know why, or of all of them cause issues, but a co-worker bought one for his HTC and was having a lot of issues.
For the battery drain you should at least try to diagnose what is causing it. Either install Wake Lock Detector (free on Google Play) or Better battery Stats (paid on Google Play, free on xda).
Most of my battery drain are constant and numerous wake locks caused by Goolge apps, including Keep and Google +. Once you know what is causing it, it will be easier to fix.
Update for anyone with similar issue..
I followed a guide on here to get back to factory stock (no root, stock recovery, etc). I had problems getting into download mode at one point and thought I was completely bricked until I decide to try booting without the battery even in the phone (powered just by USB). I was able to get into download mode that way and revert to stock.
Here's the strangest part to me: battery life is now back to normal. Not just regular use and standby, but completely powered off, I now only loose 0.5-1% an hour where I was loosing ~7% when powered off.
I don't know if it makes a difference, but I've also been keeping my wifi off. I'm experiencing terribly weak wifi transmission (still trying to figure that one out) that will cause my phone to loose wifi connection, or it will stay connected but is unable to load anything. Maybe my wifi issues relate to the crazy battery problems. Who knows.
Hi I have the same issue on my Galaxy Note 3 N9005. Battery drain when phone completely off. Can't turn on after swapping battery without charge. Tried factory reset, flash stock rom issue still exists. Any suggestions? Thanks.
For some reason my battery is acting like it barely wants to charge. It'll take hours just to go up by 4% and once it reaches a certain point, it no longer moves up in percentage. Sometimes it stops at 14%, sometimes it stops at 32% and sometimes it stops at 8, it's completely random. Also when I restart it, the battery percentage is completely different than what it was before. The weirdest thing is that the battery percentage actually decreases sometimes while it's on the charger. Even when I cut the phone completely off and it's showing the battery charge icon, the phone drains in percentage. This just started a couple of days ago, maybe a week after I flashed a kit kat rom.
Did you even check your port or chord? I would flash back to stock to make sure that it isn't the ROMs fault. Though it could be the battery?

This has happened to me with third party batteries so try another battery and another charger. I'm running kit kat on my S2 and battery usage is quite a bit better.
I had the same problem, I tried different USB cables, flashed back to stock, nothing fixed it. I finally figured out it's charging port was going out. I took it to a place they had it replaced in 30 minutes, I'm now able to charge my phone fully and my battery life is back to being great.
Hi, recently I replaced that battery of my mi9se by myself (so it is possible that I screwed up in some way), afterwards the new battery started to last incredibly less than before, having a very strange behaviour concerning its charge level: let's say the phone is charged to 100%, then in the next hour or so the battery drains normally, let's say to 80%, then it starts freefalling to 60/50% then the phone dies at 40/50%. When I connect the charger, apparently the battery is at a dead 0%, it takes very little time to recharge to 100% and the cycle continues.
Obviously this situation is not sustainable in any way, yesterday evening I was on a call with my gf, my phone died at 70%, I connected it to the charger and powered it up, as soon as it booted it was at 10%, then I disconnected it for flipping the connector and it died again... Another boot and it jumped straight to 43%. I don't know what to do...
The situation wasn't so critical at first, but I also tried to order a third battery, but the results are the same.
Another thing to note is that I also changed the charger pcb, the one onto it is soldered the usb-c connector, because it was flimsy af. I thought the cause of my problems may have been the crappy one, advertised as new but probably used, that I ordered from china. But I also tried to replace it with the old original one with no apparent changes besides the fact that now the charger doesn't remain plugged as an added bonus (that was the initial reason that led me to change it in the first place).
Software notes:
I'm currently running the latest official build of lineageOS, I could try to do a software update, but idk if it could change something...
I have root access with magisk (if some low level root operations are needed I should be able to perform them)
I was running Advanced Charging Controller (https://github.com/VR-25/acc), that I uninstalled yesterday when it came to my mind that it may be messing with the battery readings, but without success.
I should also note that I run several calibration cycles as advertised on many forums: charge to 100%, let it die by battery drain and charge it again to 100% without interruption and without powering it up. No improvements.
Sadly I study offsite and I left the old battery at home, so I have to wait till next friday if some solutions involve using the old battery.
Thanks for saving me and my phone, that, beside his battery, it still works like a charm! Switching to lineage seemed to give him another 2/3 years of life and I really wanted to keep it as long as it works.
Thank you very much for your time!
