Newbie here - I have a stock G Tablet.
Have added many apps and also Flash and it is working great.
My one concern is that however long I charge the unit,
I can't get the battery indicater to go above 93%.
Is anyone else experiencing this ?
hello there,
yes i am having the same problem. no matter how long, mine can't get past the 95% mark. clockwork mod + tnt 2.2
ideas on how to fix this, anyone?
regards
Try to recharge with the device powered off, and let it charge for at least half an hour after the light turns green.
I've left it plugged in a good 2 to 3 hours after the green light came on.
It still only reaches 93%.
Is it a bad battery, bad charger, etc.,
Any thoughts... anyone ?

Do a full cycle, all the way dead and then charge as stated for about 30 minutes after the green light comes on. It could be just a calibration problem. How long is the battery lasting for you?
I use it for short periods throughout a day, so it is difficult to gauge an accurate time.
A rough guess would be approximately 6+ hours.
I always thought it wasn't good to totally drain this type of battery ?

I think this is a LiPo battery - if so, then its is OK to let it drain all the way - just don't do it too often. You should *always* do two full discharge/recharge cycles on any Lithium-based battery as soon as you purchase it, and again about every month or two.
For removable Lithium-based batteries (i.e. *not* for gtab!), if you aren't going to use the battery for, say, more than a week, the best thing to do is to discharge it to about 50% and then put it in the refrigerator. When you are going to start using it again, let it warm to room temperature for at least a few hours to a day (depending on how big it is), *then* put it on the charger. Absolutely do not charge the battery cold as the thermal shock could damage the battery.
The initial discharge/recharge cycles "primes the pump" so that you get the maximum capacity out of the battery (who knows how long the battery has been 'sitting on the shelf'), and the ongoing discharge/recharge cycles keeps the battery at its maximum capacity *and* allows the calibration electronics more accurately track the slow decline of the battery's capacity.
BTW, my gtab's battery lasted on-and-off for almost 2 1/2 days. That was 'sleeping' it at night (*not* turning it off!) and using it on-and-off wifi/surfing/playing AB during the day. I must say, the gtab's battery life is phenomenal!

Thanks. Tried the full discharge and then full charge with the gtab turned off, left for about an hour after the green indicator, but still stuck at 95%. Even deleted the batterystats.bin file. no change. must i do two cycles of full discharge and charge?
I'm having similar issues. I powered off my gtab overnight and let it charge for 8-9 hours and I have not been able to get the battery to say 100%. I'm going to leave it on all day and let it discharge completely and try again tonight.
Drained battery and left it charging overnight and while I was at work (15+ hours) and its still at 95%. I wonder if I should exchange it now.... I'll give it another week....
If you do two full discharge/recharge cycles and the battery is still not showing 100%, then I would take it back. Either it is the battery or the battery calibration electronics that isn't working (my bet would be the battery). Furthermore, since the battery is "not removable", its just not worth keeping it and taking the chance.
If the battery had been removable, then Viewsonic could have just sent you a new battery instead of having a whole gtab come back....
(Note for Viewsonic - this is where removable batteries are superior to non-removable!)

Before you return it check the actual battery life. If it turns out that it's just a calibration issue and if your happy with everything else, perhaps you should keep it.
Read the thread about my battery test...
mine is different... I can charge up to 100%, and keep using it for few hours at night, put it to sleep, then I wake up in the morning and find the battery completely drained... any1 has the similar issues??

You can try going to settings/applications/running services and turn off all non-essential services before putting it to sleep.
Mine doesn't get above 96%, will have to try the suggestions here but overall I'm still very happy with battery life of the 96%...
thanks, i'll definitely try that... but I don't think I have too much installed or services running since I flashed it with the new ROM.
have you guys notice your battery temperature? i got 2 gtab but both operating at different temperature 1 at 23-24 other is around 31?
My battery life seems pretty good even though it doesn't go higher than 95-96%. I saw in another thread to try resetting battery statistics in clockwork recovery to see if that will fix the battery display problems. I'm going to try that next.
I've got the Malata Zpad (SMB-1002-3G) and mine now wont go over 91% (happened on the 3rd day). It used to charge to 100% no problem for the first two days.
I did a recovery (format) when you press the power and volume up button, but that didn't seem to do anything (other than wipe all my settings and put it back to original factory settings of course)
I'm pretty sure the battery is fine, and lasts just as long, but it would be good to be able to reset the battery status.
PS: My Zpad is not rooted or anything. It's pretty much standard (just running Launcher Pro).

Do you have Clockwork installed by chance? If you do you can charge the battery all the way up and then go into clockwork and reset the battery stats.
Might help...
Is it necessary to calibrate after flashing a new kernel?
Not really. I found my battery life is better after I flashed the new voodoo kernel by jt. If you do have some bad battery life, it would be suggested you do calibrate your battery.
how do you calibrate your battery also i notice after i charge my battery all nite the next morning i start off with either 99 or 98 percent any reason why???
Calibration of the battery isn't really required if you flash at 100% each time.

This is expected behavior designed to protect the life of your battery. basically what happens is your phone will charge to 100%. It's not good for a li-on battery to stay at that stress level so the phone will then allow the battery to discharge to 95%. Once it hits 95% you will start charging back up to 100% and the process will repeat. If the phone didn't do this the battery would degrade much more rapidly.

hi.
I am using CM7 now which is great, but since I am going to a trip abroad I need to temporary change to a ROM with GPS, but most inportant, with a great battery life.
I don't need any great performance like CM7, I just need the battery to last long.
Any recommendations?
Thanks.

from my experience best battery i have on this rom i flashed this rom yesterday and charge it to 100% and run batt calibration it is preinstalled in this rom when you run batt calibration after that unplug your phone from charger and use it till total discharge and do not turn your phone on charge it to 100% again and its ok i've did it and play some games wi fi is enabled always i've use gps for 15 minutes and from yestarday till today so now i have 82% batt so i thing this is the best for batt
oh by the way lag fix is enabled to
Thank you. Do you know if calibrating the battery is useful even if I have one extra battery and I switch between the two batteries if necessery?
I don't know about the two battery thing, but i do agree that Project V have great battery life. Im using Super Dragon Modz kernel OCed to 1.3, and the phone its doing pretty nice till now. I unplugged it like 2 hours ago, and it still show 100%. On CM7, i would be around 75 to 80% by now. Battery life was the reason that i came back to Froyo.
WOW that's great battery life! Thanks a lot.
i don't konw about 2 batteries but calibrating is usefull it's helping 98% bug after unplug and it's greating a new battstat file what is realy nice project v6 is very good rom for battery i did't tried super dragon
I don't see how callibrating the battery helps extend battery life? The battery remains at the same capacity and draining any battery completely shortens the lifespan of the battery. I can see that the system might get a better prediction of battery life... But you get that regardless after using the phone for a few days / week...

I'd like to know that too!
I found some baterys on ebay...... they looked kind of "strange" so I decided to keep searching.... nothing so far
Where
Where I can buy a battery for my Folio?
I found some batteries on ebay at http://www.ebay.com/itm/Genuine-Ori...8-battery-PA3836U-1BRS-PABAS238-/270859820087 . On contacting the seller he said that the batteries were original Toshiba manufactured (or made by their OEM for batteries), and thus had original Toshiba labeling. However, the battery was identical to the existing one, not a larger capacity battery. Any found larger capacity batteries?
Battery life fix from 2,5 hours to 5,5 hours!
I bought a used folio and in the original OS it had battery life of 2,5 hours after couple of complete charges. I then installed ICS CM9 and no change in battery life, the device shut itself off after 2,5 hrs.
Well after Googling I decided to try the battery stats reset in CWM. After 100% charge I did the battery stats reset in CWM and went to ICS to test the battery. After about 2,5 hours battery meter was showing 6%. 3hrs still 6%. 4hrs still 6%. 5hrs still 6%. Only after about 5,5hrs it dropped to 5% and about 15mins after that it was 1% and my device shut itself off. What an improvement! And I was using wlan and watching videos etc practically the whole time!
To fix the battery meter showing 6% for several hours I have used the device many times from 100% to lower than 6% and then charging the folio with power on. Now it shows 6% only for 45mins or so and I bet after couple more cycles it will be perfect! Then ill run it to 0% once more to be sure to make use of the whole battery.
So before you buy a new battery this is definately worth a try.
PS. You don't want to drain the battery to 0 % very often because this too will have a negative effect on battery life. Maybe once every 20 cycles is ok.
Wow, I'll try to reset it on CWM and see what happens. With a normal use is lasting about 3 hours before shutting down.
Do you have news for battery?
Thank you in advance.
Hi guys,
I want to share to those that may be doesn't know how to extend battery for a little bit.
I have tested this method for months and it works well on my D802 G2.
Here how to do it :
1) when you charging your phone and the battery status shows 100% don't unplug your charger yet
2) touch your charger and if it still hot, don't unplug it
3) you can unplug your charger when it is became cold, on my case, it could took around 15-20 minutes later
See for your self, if it could improve your battery life. For me, it is like having a 110% battery capacity.
For best result
Charge your phone while it is off and battery level not less than 15%

Yeah, I got it. i saw when i charged my LG G2 over the night, tomorrow its battery decreased very slowly. But sometime i charged it around 9x%, the battery decreased so fast @@
Yeah right.
I'm doing this since still using G Pro,
100 to 99 = Insane
99 - 98 = At least better than normal
98 - 0 = Normal
I use Android Tuner, you can see what your actual charge voltage is and track when it really is full before you unplug.

i just leave my charger plugged in. when i go to bed, i plug it in, and 6-7 hours later i unplug it. it trickle charges when it gets to 100% anyway. meaning the charge goes down a little and goes back up a little. yes, i guess this wastes more electricity but it is so minor. also the G2 has a capability that when fully charged at 100%, the voltage of the battery is different, so the battery lasts longer at the 100% mark. once it hits 99%, battery life starts to drop at a normal rate. i read about this in another post on xda, forgot where. it used to take me 25 minutes of watching an HD mkv file at max brightness on mx player to drop from 100 to 99. nowadays it takes 20 minutes.
The best results will be if you charge the phone from PC usb port,charge it at night and take it in the morning.
It sounds good. I'll try it.
Thank you!
For best results charge your phone in the freezer.....
Ok just had too
But this is true ^. LOL @woof123, a slow charge doesn't change a thing with these batteries. Fast charge doesn't even get hot enough to be detrimental. The top 1% idea is indeed true. I'm gonna make a slim refillable liquid nitrogen cartridge to place over battery. Win.
Im not talking about battery degration from fast charging,by charging my phone over the usb i noticed that it lasts longer vs the charger.
Just use greenfiy and the donate version
Hibernate every app besides system Apps.
Nothing will run ever again in background while hibernated.
And yes it works and no the app itself does not cause its own drain.
Greenify is highly noted in every forum across xda

With these non removable batteries, I'm more concerned with ensuring that I don't harm the battery. I was reading that leaving it charging past 100 percent might shorten its life span. I've been using. Battery full notifier to avoid doing that.
Sent from my LG-LS980 using XDA Premium App
The general behavior of charging batteries like these is that the first 80% of the actual battery capacity gets charged very quickly (usually takes 1-3 hours) then the last 20% of the battery trickle charges (this also takes another 1-3 hours). I think what's happening here is that the phone itself only reports the first 80% of the actual battery capacity because that's the part that charges quickly, and anything over what the phone reports as "100%" is the last 20% of the actual battery capacity trickle charging.
As for any harm this could bring to the battery, batteries like the one in the LG G2 last longer if you avoid deep discharges (e.g. charging to 100% from 50% at the end of the day versus charging to 100% from 0% after every two days), but it might not even matter since LG Chem's higher end batteries tend to be rated for at least 800 full charge cycles (last year's average smartphones were rated for ~500), which covers over two years of very decent battery performance even if you were to charge from 0 to 100+% battery every day. Even if you use up all these charge cycles, you're still going to be left with ~70-80% battery capacity of the phone you initially bought.
A side note from all this is that any anecdotes of long battery life (where the initial battery percentage reported was 100%) is generally unreliable because it's not conveniently possible to know how much over "100%" the phone's battery has been trickle charged.
My battery life is ridiculously good on this phone anyways...

It's true, 100-99% yields insane use time, but only if you use an app like Battery Monitor Widget to let you know when the battery has stopped accepting power (+0 mA, voltage ~ 4370 mV). It is also true though that this reduces overall battery health a little (it might become noticeable if you do this all the time).
And btw, charging overnight is a very bad idea.
