Battery staying at 100% and not coming down - G Tablet General

I just got my Gtab that I ordered from ebay in the mail yesterday.
The guy already had clockwork recovery installed and TNT, but I wanted Vegan, so I went through the steps and installed Vegan 5.1, let it boot, and then rebooted and installed the supplement 5.1.1.
The thing works great (except I can't get any market fix to work, but I'm just gonna use titanium backup to get the apps from my phone for now).
But the thing that's really bothering me is that the battery level is staying at 100%. It's not going down at all. The GTab died overnight, and it wouldn't even power on, so the battery was dead.
I plugged it in, and turned it on, and it's showing as 100%!! When I goto settings>about phone>status it force closes. Every time. Using spare parts and looking at battery history it says there is no history to display, and in battery info it says battery is at 100% but says it's charging.
I'm really confused. Do I have a dud battery? Please help as if this is a hardware/ bad battery problem I'd like to tell the guy on Ebay that I want a refund.

Does the charging light come on red, and go to green after it's charged?
You might try wiping battery stats with Clockworkmod, and see it that helps.

Same thing happens on my Gtab. Battery meter always shows 100%.
I know that the battery is not 100% full because when I plugged it in, the LED light is red and after a while it turned green.
I will try your suggestion tonight when I get home.

Yes, the battery light indicator seems to work fine. It is red, and then eventually turns green. But I'm a little worried, how long should I be expecting a good battery to last with brightness pretty low (around 15%) and just doing some browsing? I was guessing 8-9 hours.

I haven't tried to drain the battery. I always use it for a few hrs then plug it in.
Does any body know how to fix this problem?
thanks.

Try to drain it all the way, then plug it in and immediately reset battery stats.
Reboot and charge all the way ( green light)

I tried this but it still doesn't seem to work right. After following your suggestion, I used my gtab to browse the web. After about 1hr of browsing, the battery status changed to 97%. It does not seem right to me. Btw, my lcd brightness is set at 50%.
Or is the gtab battery that good?

Haha, yes! I get at least 20 hours with moderate use. On standby, it seems to last forever.

They are threads here on how to correct - usually draining the battery and then resetting the battery status on clockworkmod.
It's really not "Stuck" at 100% - the battery meter is probably off so it's maxing out at 110%, so your device just says "100%" all the time. What eventually happens is that 110 drops below 100, and then your device will show 99, 98 etc. I had this issue on my original GTAB.

I had this and first total drain didn't work but 2nd time I just made sure it was not sleeping when it shut down from low battery.

battery only chargers to 95% ?

Is this normal. I did try and do a search in my defence.
Yes. It is like that by design. It stops charging at around 95-98%. Its to prevent you from overcharging the battery.

This is a known issue. You can try and reset battery stats in cwm when your battery is charged and/or emptied. It works for some and not for others. I haven't noticed my battery lasting any less when my battery doesn't "charge" past 97%
There have been some discussion on this. I get about 97% myself. From what I've read you may get full charge if you let it drain all the way. I don't do that myself. Very happy with battery life as is.
I used to get 100% before I switched to the Vegan rom.

Either let it drain until it shuts off a few times and then charge it all the way up or if that doesn't work, use CWM to delete the battery stats when it's at 95% (full, with a GREEN light - not charging, with a red light) and then let it drain until it shuts off on it's own.
I did this a long time ago (delete the stats) and it's been perfect since. Charges to 100% and does indeed show battery at almost empty before it shuts off.
Good Luck.
Still no go here but it can get tom 96%... lol
I am sitting a 98% with VEGAn.
I am now having an issue where u can use the device, then I turn it off, and
turn it on the next morning and see about 5 to 10% of my battery was drained.
Confirmed Fix
Confirmed fix for me on Vegan 5.1. Letting battery drain down to zero and shutoff the tablet... reached 100% on next charge. Now the indicator charges to 100% every time.
tried this and still no luck . still get to 95-6% bugger
Vegan here..this is how I fixed it:
1) Drain it till it shuts off, try restarting it a few time to make sure its dead.
2) Once dead, plug it in, boot into clockworkx, and reset battery status (do this quickly)
3) restart, and leave plugged in idling till fully charged
4) use and enjoy a accurate battery level!!

You have to remember that in order to install some apps out there, you have to give them permission to use the internet and to interact with your device autonomously. I have found a few apps that were pulling my tablet out of sleep mode and turning on the wireless to download ads or other updates, and that (along with the length of time to shut back down) was affecting my battery life.
I would say to go back and review what you've installed, and to also check your screen timeout settings. Just doing that saved me quite a bit of overnight battery loss.

Defective thunderbolt battery?

Good Morning everybody!
I think I have a defective thunderbolt battery, sometimes when I pull my phone off the charger it drops to 95%. Funny thing this is not a everyday thing. Anybody having a similar problem like this? Sorry if this been discuss before. Have a bless day everybody...on my way to the office.
I have the same thing happen. There is something goofy with how the meter reports battery level. If you reboot your phone it drops even more.
Sent from my ADR6400L using XDA Premium App
Yea I notice that too. I seen my battery drop down 15 percent after rebooting. Is the battery defective? Or the phone is defective?
Bump charge it. Charge it all the way. Unplug, turn it off, then on, and keep charging.
Sent from my ADR6400L using XDA App
The phone/battery aren't defective. I have the extended battery so I never bump charge it, but he is right. Charge it up until your charging light goes green, unplug it and then turn it off. Once it shuts down, plug it back in and will now be orange. Charge it until it's green again. Sometimes it will take a few minutes, sometimes an hour. I'm also color blind so I can never tell whether that damned light is red/orange/green. >.<

is this all the time we have to do, I have the extended battery and it doesnt drop and I read about clearing the batterystats.bin but is this something we always have to do when we charge the phone? when I use the standard stock battery it drops with no problem
I didn't have any issues until I wiped the battery stats and now, my battery is constantly inconsistent. I would not recommend doing it as it has nothing but a pain in my arse since.
Have tried "bumping it" which essentially means to charge it to 100%, restart it, then charge it back again from whatever it dropped to.. Mine initially was around 85ish.. After a few "bumps" it crept up to 90 or 91 and then wouldn't go any higher. I charged it back to 100% and decided to follow the advice from another article which said to let it deplete to 0%.. In doing that, surprisingly it "froze" in a couple of places, I don't recall the 1st % but the 2nd % was definitely at the 28% mark. It literally sat there for a good 2+ hours with screen on max and didn't go down. Eventually it went down to 1% and I charged it back to 100%.
Issues still remain, wondering if I should've let it completely die out and force itself off?

Where do I get into CWM, to do this?
Thanks for your help everybody! I'm sorry if this is a dumb question...what is CWM? My device is stock.
CWM = Clockwork Mod.. Goto Market, download ROM manager, then you can flash CWM. Not sure if that'll do you any good if you're not rooted though.
why when I reboot my phone like 15% of the battery life drops I love this damn phone man...i cant put it down while im at work
The battery reading after reboot is wierd.
Yesterday I was at 51% and draining are at a pretty steady rate like normal. After rebooting, it showed 41% but then it say at 41% for AWHILE.. after like an hour, it read 40% and started discharging at the normal rate.

Thanks for the repost, I had skimmed this thread earlier but don't recall it being so detailed. Seems like the moral of the story is that while "bump charging" works, it's not really recommended as it can reduce the overall life of the battery. Wonderful, now I regret ever messing with the battery stats at all, although I can't say for sure I didn't have this issue prior to doing so.
My OEM battery wouldn't hold a charge even after charging it all day... I took it to the VZ store and they replaced it for free...... I also just bought the larger 2750 mAh battery.... works great!

losing about 5-10% battery on reboot

so why exactly am i losing battery life on a reboot. its happening on every rom ive used so far.
I think its because your battery is not properly calibrated with the rom. Are you bump charging each new rom you put on and wiping the battery stats?
This happens to me. I am stock currently, but I have been through two phones and they both lost 5 - 10% on reboot.
It's normal for the phone, it takes a bit to "power" up the phone. Don't stress out that much over it. The battery % isn't 100% accurate anyway.
I'm losing ~10% on each reboot too. Its definitely not just from the reboot and I don't think its accurate. Yesterday, as an example, I was at 43%, rebooted and came up at 32%. Then my phone sat 32% forever, just flat lined in the battery stats for hours. It finally started reasonably dropping again hours and hours later as if the battery level had finally caught up with what was being reported.
Have you ever bump charged and battery wipe stats before?
Cuz mmy battery doesn't drop like that.
I don't think I lose a full 10%, but I definitely notice a significant, if not excessive battery drop when rebooting. It seems unlikely that the battery could have discharged that much, so it's probably a reporting issue. Not something that really bothers me, but just pointing out that I noticed it as well.

This was similar to what I experience. More evidence that it is a mostly harmless reporting error. The reporting "corrects" itself once the phone is booted. Interesting behavior, but harmless.

Your battery gague isn't telling you the truth.
I don't even get a 100% charge. It sits at 97 for like 3 hours and then drops. Reboot usually only takes <5 for me though. I'm thinking ROM issue.

This really explains why you drop rapidly after unplugging your pone from charging to "100%". I believe the OP is referring to a step function-like decrease in battery level between reboots. That is what I'm referring to anyways. That link does have some interesting info though.
I've been having the same issue. Reboot sometimes drops the battery by 5%, and the battery gauge seems to get stuck after that. I've also noticed that sometimes if I reboot while it's charging, the % will jump something ridiculous like 20%. Just now, it was at 45% while charging, I rebooted, and now it's at 57%.
This has been happening on both BAMF and CM7, though I've always been using Imoseyon's kernels.
Same problem here. Bump charge and battery stat wipe is the fix but it's definitely a pain. Especially, since I am flashing a new rom everyday.
to bump charge does my phone have to be off or when it reaches 100 unplug and plug a few times? will that do. i hate having to shut the phone off especially for a number of hours.
Bump charge> charge the phone on till light turns green. > turn phone off> charge phone until light turns green> unplug and reconnect several times> boot into recovery> wipe battery stats. > done. Use the phone all day and let it die on that charge. Then charge over night turned on. And you are now calibrated.

because rebooting entails the re-starting of operating system, services, background apps, internet connectivity, and initial data sync. it's just the nature of restarting an operating system.

I think the question was meant to be something like, "why do I lose 5-10% of my battery after a reboot?" Of course rebooting using a little power, but that's not the issue here.

Strange battery

The last couple of days I've noticed something strange with my battery. I keep it on the charger all night and when I get up in the morning my phone says the battery is at 100% and the charge LED is green. The instant I pull my phone off the charger it drops a couple percent. I thought that was strange so this morning instead of pulling the phone off I just shut it down. Once the phone was completely off the LED went from Green to Orange as if it was charging again. It look another 20 minutes to turn green again. I powered the phone up and as soon as sense is loaded I am back to 93% battery.
Anyone else see this? I've wiped battery stats and did the whole calibration but that didn't seem to fix the issue.
That is normal... Once the batt hits 100%, the charger goes off and lets it drop to 95% or so and starts charging again. It does this to protect the battery. Also when you turn off, it will restart the charge.
The battery is lying, but that's not such a bad thing.

My battery has been acting up the last few days as well. As in, going from a full charge to ~35% in 3 hours and then down to ~12% an hour later. No new apps added, nothing out of the ordinary done. Regular uses and charging cycle. I normally reset my battery stats when I flash a new incarnation of a new ROM, but after a couple of days everything seems to be back to normal.
I've been baffled by this, but have yet to find the culprit. An app or searching for signal are my only thoughts.

Give a spin to the ROM I am on and try. Mine turns green only at 90%.
Also, do u have any LED color changing apps loaded that are getting loaded when u restore with TiBu?
I'm 99% sure this is normal operation.
Does it continue charging to 100%? Or does it stop at 90%?
Mine changes to green at 90% also. I just assumed it was normal.
Sent from my Inspire 4G using XDA App
I've only noticed the 90% green on CyanogenMod, running LeeDroid right now and the LED only turns green at 100%. I'm pretty sure this is a bug. In my opinion if this is intended to be a feature, there should be different notifications based on almost/fully charged. Maybe flashing at 90%, solid at 100%?
this is on most roms but its not a bad thing, its not like your battery life is bad its just showing when its basically done charging
It keeps charging to 100%. If you doubt it download current widget. It will tell you exactly how much power is being pushed to the phone.
Sent from Inspire 4G using Morse code.
I'm on CM7 and my LED turns to green at 90% as well. Is this something you are seriously concerned over? It's an LED color, as long as it continues to charge to 100% who cares lol.
As others have said, it is normal for the light to go green at 90%. Every ROM I've tried (except for LeeDroid) does the same thing, and from what I recall even the stock HTC ROM switches to green at 90%, which is probably the basis for most of the custom ROMs doing the same thing.
My guess as to why the light goes green at 90% is because that last 10% of charging time takes a while (due to an increase in charge trickling) and the average consumer would be waiting and waiting for their charging light to go green if it were set to 100%. The ROMs/kernels are designed to balance the convenience factor with a little loss in charged capacity.
As the battery charge gets closer and closer to 100%, the electrical charging current being sent to the battery decreases more and more. This is best practice when charging a Li-ION battery to help prolong its lifespan. In our Inspire phones I have noticed (using Battery Monitor Widget set to 1 minute intervals) that during a typical charging cycle, when the battery is between 1% and 59% the kernel or the ROM (not sure which one controls charging; my guess is the kernel) allows the battery to receive a full charge. Using the stock HTC AC adapter, this equates to around 820mA with the screen off. Once the battery reaches 60%, the software will start to throttle back the charging a little bit at a time - the higher the battery is charged, the less current is applied. By the time you hit the 90% mark, the battery is only being fed with around 100mAH of power and is still decreasing. So that last 10% takes a little while.
My stock Inspire doesn't go green until it hits 100%. I tested it twice to make sure. The last 10% does take a little longer, but still no green until charging is completed.

Well said HenryBravo.
The most efficient way it seems to calibrated your battery, in my opinion, is to first download current widget. Go to widgets and add the current widget widget to your screen. Plug in your phone, and leave it plugged in until your m/a reading says zero or 0m/a. You will see one hundred percent charged on the widget, tap on the 100 and a smaller number (anywhere from 30m/a on down will be present) it is this number that shows how much charge your phone is still drawing. Even though it says 100%, like HenryBravo stated, It is STILL drawing current, and until the widget reads 0m/a, is not fully charged. When you reach the coveted 0m/a mark, open file expert (or corresponding app) and go to the data folder. Then system. Then batterystats.bin - delete the file and reboot with phone plugged in (until reboted, then unplug) and your system will recreate your batterystats.bin file and have the proper value for a full charge. Also, this can be done by booting in to recovery, going to advanced, wiping battery stats, and rebooting. There are other calibration methods I have read of, which involve fully charging, depleting, charging again, etc... I have found this method yields the same results for me. Not all phones are the same and some phones yield various results with certain procedures, I am not sure if the battery calibration falls in this Category or not. Good Luck and hope it helps!!

When I'm running CM7 this happens to me too. But on Cleardroid ROM it stays orange and wont turn green until 100%. I think its just part of the Rom, nothing to worry about.

This is normal operation. It's not a bug. When your phone reaches 90%, that is when it resets the calculation of how long your phone has been on/off the battery.
Quoted directly from the phone manual, "As the battery is being charged, the notification LED shows a solid red light. The light turns to solid green when the phone is fully charged". Shouldn't really matter though, as long as the phone charges to 100%.

custom roms are designed to show green light at 90% charged battery.. unfortunately...
