Charging/discharging question - G Tablet General

I have two question:
- if I charge the tablet even all day it has still just 96% of power, never has 100%. Is it OK?
- when I exactly should start charging the tablet? It notice me when the battery is discharged at 15% but I think that it should go even at the lower level. What is the best value to care best the batteries?

I have been wondering the same thing. I am even letting it run down to the point of self power down

Seems to happen after flashing sometimes. I had no problem on stock and OTAing the 1st update, but after several version updates of TnT lite custom fw I did get it once where it'd say a max 99% charge, but in my case I have clockwork mod installed(must have for messing around with custom fw) there's an option to wipe battery stats which fixed mine backup.
A secondary problem that I had was that even after the 1st OTA update in stock, the batt meter would stay at 100% overly long, i.e. I'm sure that a true depleted batt would still have read 30-50% on the meter, but again I flashed custom fw and try to remember to wipe batt stats after a full charge and a new fw flash... seems to fix the problem. Not sure what to do with plain old stock fw though... maybe VS will get a fix if you have this in stock after more recent OTA updates...
[EDIT]
I also had this problem with my Nook Color after sideloading their 1.0.1 update. Battery meter would be at 98% when the charge LED turned green in the cable. Seems to have eventually cleared itself up on that one though as since then it's been getting to 100%. (No clockwork or any way to wipe batt stats on the NC as I'm running their stock unrooted fw ATM.)

Incorrect battery reporting w/ Sense 3.5

Has anyone realized this or is it just me, every sense 3.5 that I've tried the battery indicator is incorrect.
For example, I just had 41% battery life before resetting my phone and now I have only 4%. Is it not charging the battery correctly? I also turn the phone off after it says 100% and then charge until the green led comes on but still it is either draining too fast and phone doesn't detect it until a reset or the battery isn't be charged completely because the rom thinks it's 100. I have caliibrated and erased the batterystats.bin file so many times and it's still the same. any insight on this? I have a brand new battery from htc as well.
Same problem
Constantly "calibrating" or deleting the battery stats is the exact reason this happens. You dont have to do that, regardless of what people say.
This will happen until the battery has been charged/discharged a few times and will slowly stop happening.
No issue here, got my new anker battery.. Flashed BP 2.1.5 and since then, my battery has been normal and amazing!

This. When I flash ROMs I don't really do anything in relation to the battery. I just use my phone like normal. The first day or two you might get a little more drain than usual, but after that it will be completely normal and you don't have to do anything like wipe battery stats or calibrate or run it down to 5% and charge it all the way up or whatever.
Yes, constantly resetting battery stats is bad. Should only occur right after flashing the new ROM. Ideally you'll have charged your phone to 100%, flashed the new ROM, and immediately putting it through 5 discharge/charge cycles.
My battery life was horrendous when I didn't properly calibrate the battery. Going through the process now and its lasting a significantly longer time compared to not going through the process. I'm talking about getting like 6 hours of light usage compared to like 15.
Or it could be just ARHD. I really didn't like that ROM. Anyways, I'm running Bulletproof 2.1.5 with 3.5 Sense on an Anker battery and its doing great.

I'm gonna have to disagree with you on that. My battery life was horrendous when I didn't properly calibrate the battery by going through at least 3 full discharge and charge cycles.

+ 1 my battery was shocking, im on my second full cycle currently at 2% lol and already i've noticed improvements by like 20%

I've done everything, calibrated the battery numerous times with and without wiping the batterystats.bin and it's still acting up. Say this morning I wake up, take the phone off charge at 100%, go out, and restart the phone for any reason when the phone's battery meter is at 95%, after the restart the meter will jump down to 70%.
This is with a new battery, new rom, totally wiped device, I even used the ruu to get me back to the stock rom.
Anyone have any idea what's the problem? The battery life is ****, and doesn't seem to get any better with calibration.

This is your culprit. Let it bed in a few days, and performance should stabilize.
Go through 5 full charges/discharges, uninterrupted. Yes, it's a pain in the ass, but you signed up for it when you flashed a new ROM.
Everytime you wipe your battery stats, you have to go through the 5 cycle process again. Uninterrupted.
EDIT: Had a lil too much rum and misspelled a few words. I even misspelled mispelled
Alright dude, I'm going to take you up on your word, I'll give you another update within 5 days.
This is a problem with all Sensation ROMs, even with S-On and Stock ROMs. I get a problem like this one too. If I have 60% left, and I restart the phone, it goes up to 69% and I don't know why. Also very slow charging from the original wall charger, but if I reboot when it's charging at 70-75%, when it finally boots, it says 100% charge. This must be some bug from HTC or something. :S
Hi,
Same problem (with Sense 3.0/Sence 3.5 and different ROM),but is there a fix for that?
I saw this:
Batt Jumping hopefully solved (Beta) = Done

The thread: http://forum.xda-developers.com/showthread.php?t=1287129 .
Probably a way to fix the issue?
Should be asked about this in the ROM thread?
Me too same bug since first day, I think it's a battery sensor fault
It's not a hardware fault...it's not a battery fault...it *may* be a ROM/kernel issue...but I suggest you give your battery a few discharge/charge cycles and you'll see it should go back to normal.

[Q] Battery Half Charging

Alright so it's difficult to explain this fully but I'll try. I came across battery calibration information and I went ahead and wiped the stats. I then let it drain, charge full then drain again. Now as it was charging I decided to flash another ROM, done. So that ROM took a while to fully charge but when it did I got 13hrs of battery life out of it. Now when I charge it, pretty much it stays around 50% and wo't bump higher. Literally haven't hit higher after leaving it plugged for more than 3 hours. Anyways I'm about to flash a update of said ROM and use a different kernel that is know to be more stable. But curious if there is hope for my battery? I don't plan on wiping battery stats anymore, after further readings I see it's not worth the trouble.

[Q] Flashing ROM's at less than 100% battery

Will flashing a ROM with less than 100% battery harm anything?
My wife's phone is still having issues with the NEWsense rom after getting a new battery from sprint. I flashed NEWsense while the phone was charging, at the time of the flash it was at roughly 45%. When charging, it will say it's charged to 100%, but after 3 hours of light use with wifi on, it's down to 27% already.
Is this something the battery calibration option in the NEWsense control panel would fix? Or is wiping battery stats the best way?
I could always charge to 100%, then re-flash the rom.
I guess I'm just lost as to why this keeps happening.
I flash ROMs with whatever battery I have left and never had an issue.
I don't wipe battery stats because each time the battery charges to full the stats are wiped anyways.
A new battery can take a few charge cycles to start performing like they should so just give it some time.

Did you do a Full Wipe before Flashing the Rom? Did you Restore any Data? In WiFi do you have it set for WiFi-performance? What is your WiFi-sleep Policy set at? Oh BTW did Sprint send you a 1500mAh Battery, or the 1400mAh Battery?

Is my dock battery toast?

Hi,
KatKiss KitKat v33 user. Loving the ROM. But recently my dock battery is going from 100% down to 0% in just minutes of use and from 0% to 100% charged in just minutes too. It previously worked great. Tablet and dock are about 3 years old. I've stayed away from depleting the batteries. I've tried flashing (wiping too) the ROM again without resolving the issue. I'm currently trying a trickle charge but don't expect success there either.
Am I missing something obvious or is this just your typical dead battery?
Sounds like end of the batteries life if you've 100% wiped and re-flashed everything
Can't remember off hand but I feel as if there is a Wipe battery stats option in TWRP you could try
Just had a look through TWRP and didn't see anything related to resetting the battery. ??
I'll see how the trickle charge works.
Hmm, just checked and can't see it either, was sure Id seen it somewhere
There is a way to do it, maybe it's not built in and needs doing from terminal or a flashable zip
If I work it out i`ll let you know
EDIT - Looks like this does the same thing
https://play.google.com/store/apps/details?id=com.nema.batterycalibration
Let it trickle charge overnight and then charged with the asus charger this morning and it seems to be discharging normally (if quicker) now. Will have a look at that app, though.

Battery Issue

I have been using Nexus 5 for a year and half now. After upgrading to android 6.0.1 recently, I have been facing serious battery issues, such as:
1. Sudden shut down of the device, from various % of battery remaining. After trying to switch back on, the battery shows empty, or even 5-10% charge remaining.
2. If I charge it fully and then switch to safe mode, the phone works fine, the discharge rate is pretty stable and long-lasting. If I then try to switch back to normal mode from safe mode with a simple restart, the battery percentage again shows drastic change in between the two modes.
3. Sometimes when I keep it in safe mode, the battery percentage shows an increase, even if it's not charging.
* Yesterday I did a factory reset, yet these problems continue. I am confused about this being a battery problem, android bug or something else entirely.
I am a newbie in this forum, so please pardon me if I am missing some things here. Any help would be much appreciated. Thanks

Yesterday evening I charged my N5 to 100%, used it 5-10 minutes while in bed and turned it off; this morning I turned it on, used it for other 5 mins (the charge was 86%) and it shut down on its own: when I tried to switch it back on it appeared to be completely discharged.
This happened several times in the last weeks, alongside a way faster discharge of the battery.
Is there a way to check if this is related to some software or it a physical problem of the battery? And, in case, is it possible to change it?
Flash back to stock LP to see if the problem goes away. If the problem continues, it could be time for a new battery.
I've not been playing with roms and stuff for a while and I don't remember that, if I flash stock LP (I'm on stock Marshmallow now, if that matters) will I have everything on my phone wiped?

...anybody?
You could try flashing everything except the userdata.img file. After flashing the other partitions, erase cache before booting the LP ROM for the first time.
I always recommend taking a back up of your data before flashing anything to the phone as there is always the possibility that something goes wrong.
What about calibrating your battery?

I tried to install an app to calibrate the battery but I'd need to root my phone to make it work (as now it's not rooted), and if I remember correctly the root process would wipe my phone (and as right now I don't have much time for that I'd rather try first everything I can without wiping).

Alright, though I'm afraid it might come down to that..
But lemme know anyway if you managed to fix your battery issue without having to calibrate the battery. I had a similar problem but it hasn't gone away yet even after calibrations. Maybe a new battery is in order.
