Hi all!
I recently flashed Trigger + Overstock. The problem is related to battery drain. I am trying to re-condition the battery/wipe battery stats...However, My battery will not charge to 100%. It stays at 99%. I assume this isn't normal. Wondering if anyone else has come across this before?
Any ideas? Or can someone point me in the correct direction to fixing this?
Thanks!
My devices usually stay at 97% no matter how long I charge it.. Sidekick 2008, iPod Touch, Vibrant, even my computer.
I'm not sure why.
Yeah...it's just weird. I mean it used to charge all the way up to 100% and even notify me that it was completely charged before I flashed it.
By no means am I complaining about it. I just was wondering if that was normal after a flash. Also, more importantly will re-conditioning of the battery still have the same effect even though it's not at 100%? That's my real concern to get good battery life without going back to stock.
Thanks!
I had the same issue for awhile and honestly it seemed to more or less resolve itself after a few charges. I don't know if that was just my experience of the ROM updating the battery stats.
Have you fully charged the battery and wiped the battery stats? Even after doing so, it may take a few charges for the ROM to fully recognize the proper battery levels.

Yeah, I fully charged it...well to 99%. Then wiped battery stats. Hopefully like you said it will correct itself after a few charges.
In regards to wiping the battery stats, did you use root explorer and delete the batterystats.bin file in the system folder or did you try to wipe the via the CW Recovery menu? I personally never had much luck doing it through the menu.
Been using the g tab since December and have always been impressed by its battery life. Only issue was the battery meter never seems to reflect the true battery level. I had times when it just shut off without warning with the battery meter at 100% while other times, it drained rapidly to 0% within 20 minutes.
I know the general fix is to delete battery stats with recovery (which i have been doing frequently) but that still doesn't quite solve the problem. As such, i decided to test the exact battery life of the tablet. I am quite shocked at just how good it is o.0.
I've had a (1hr 17 mins) video looping with wifi on and connected for exactly 9 hours now as i am typing this. The battery meter still reads 100% but i think it will turn off/drain rapidly soon.
I am on TNT Lite 3.1.4 btw (old but gold).
Update: Tablet just shut off after 10h and 56 minutes on video loop + wifi. Video was stored on tablet memory.
Issue: Battery meter never drained and was 100% till death (i plugged in and rebooted and it read 100%). I had just wiped battery stats before doing this experimental run. Any suggestions to deal with the battery meter issue?
I had a similar problem with another tablet after wiping the battery stats and still don't know if that was the issue or not. From my recollection, you were supposed to discharge the tablet completely and then delete the battery stats (or was it charge it completely?). Is it possible you deleted it in the wrong state, so it thinks an empty battery is full? I always wonder if I might find a similar fix for the other tablet or if the charging hardware simply failed (not a gTablet -- a flytouch2 type device).

From what I've read about calibrating the battery on other devices (specifically in the EVO forums), you're supposed to charge it until it's full, immediately wipe the battery stats, run it until it's dead without turning it off at any point, then charge it until it's full with the device off. Turn the device on and it should be properly calibrated. I'm not sure if this will fix your problem, but it's worth a try.
If that doesn't work, you could try flashing a different ROM and see if the problem persists (backup everything in clockworkmod first, so you don't lose anything if you want to go back to that ROM). If the problem goes away, it's probably an issue with TNT Lite 3.1.4. If the problem persists, it's probably an issue specific to your gTab.
Thanks guys. Ill give it a go.

I've been having an issue where my battery show that it is discharging but then it abruptly shuts down when it hits ~50%. No warning of low battery voltage.
I'll try this calibration and report back with results.
Update...8 months on.
My G tablet is now running Flashback 10.3 (finally HC is stable enough).
Battery still does not reflect drain, stuck at 100% every time. (i've been told its a kernel issue)
On Flashback 10.3: Looping a youtube video (1hr 14 mins) with HD on, sound off, wifi on, brightness set to automatic in a dark room. Tablet died after 9hrs 21mins.
This is 1.5 hours shorter than the result i obtained when i looped a internal storage video, wifi on, brightness automatic, sound off 8 months back on TNT 3.1.4 (froyo).
I'm pretty impressed given the 3700mAh in our device (compared to most 5000mAh tablets). Anyone done any tests? Do share.
Two questions:
1. what sort of battery discharge rate would indicate that my tab has a problem? i was reading using aldiko last night for about an hour, and the battery went from about 85% to 70%. it seems like this is higher than it should be for just passively reading an ebook. thoughts? does this battery burn rate seem legit? how do i know when i have a problem? is there a good way to test my battery in terms of whether or not i am getting teh batery life i should?
2. the battery stats in "settings" are not working properly. there is no breakdown of which components are using teh battery. there is nothing under teh graph at all. any one else have this issue? thoughts on how to fix?
I've had my G-Tablet for over six months and its awesome. The specs are very high for a older tablet so JB Smooth Bean works great. The problem I've had since the first ROM is the battery status. It never charges to past 96%.
I've wiped everything on the tablet! Cleared the battery status in the rom, discharging the batter to 0% and then wiping the battery status in the ROM before charging!
Battery life is still 10hr so the batter holds a charge. I'm wondering if the battery is bad or is it a system issue.
It's a known issue. I haven't been able to fix it myself but then again it doesn't bother me too much. There might be a solution on the forum somewhere...
Hi There:
Not sure if anyone is exprience this problem.
My battery completly drains a second after it says is at 40%.
I've installed several ROMS (Cianogenmod 10, toldo's, official) to see if it was a ROM problem. No luck. I'm current in toldos's v7
Installed several Kernels, No luck. Actually i'm with A1 kernel
Tried several battery calibration aplicacions apps. No luck.
Problem presists.
It`s not that the battery drains fast, is that everything goes oK till battery reaches a point below 40% and the next second it says it only has 2% or 1% and can stay there for some time (even two hours sometimes.
Anyone has any idea what could be happening, because i don't think is a battery problem.
Thanks evey one
fault battery
probably the battery is gonna die
