When I first got my touchpad the battery life on it was fantastic, days on one charge. Ever since the latest webos update it seems as if my battery life has been cut in half. Example this morning pulled off the charger at 6am and now its 8am and its already at 80% and I haven't done anything at all on it. Its been asleep the entire two hours its been off the charger...anyone else have this problem or solution?
I noticed that battery life got a little worse but not that worse (in my case)
I don't have any numbers to back me up but I'm pretty sure I can leave it in sleep mode overnight and not losing more than a few percent.
I'll check out tonight as I charged it overnight and left it unplugged when I left for work. I'll see what the battery says after 10 hours of sleep.
Damn that's worse than CM7 Alpha... webos was fantastic using minimal batery during sleep
WebOS wasn't alpha code.
Install cpuspy from Market, charge it to 100%, open cpuspy and tap on menu and reset stats. Then unplug from charger and blank the display and let it sit for an hour. Then wake it up and tap menu and refresh. Last I checked, in 9 hours I had 8.5 hours of deep sleep, then mostly lowest speed (384) and a couple minutes of 1700.
Your other option is to go into your battery stats (under settings) and see what's been using your battery.

You think this will really work? I mean installing an android market app under webos.

my touchpad got charged this morning. unplugged it at 1 pm now its 11 pm and i have 93% left with 20 minutes of surfing the web and the rest sleep. i have 3.0.4 on my touchpad no chroid or cm alpha. and it wasnt better on 3.0.2
edit: i forgot: i have f4 phantom kernel installed and overclocked to 1.7 ghz since i got my touchpad.
I still get days of battery life out of my TP, and I use it often.

Heck no. I thought you were on CM7.
I guess you did say webos in your first post.
Haven't had any issues. Haven't plugged my touchpad in for a few days, still at 100% battery, and touchpad is overclocked to 1.5ghz with deadline i/o scheduler.
ok so I checked yesterday.
I unplugged it around 7am and let it sleep, unplugged, with full battery until 6pm.
Battery was still at 100%.
I didn't plug it back in last night so I'll check what's left tonight and the usage details but so far, sleep mode is not guilty for me.
Maybe it drains a little more in use than before however.
its so funny that after I make this post the battery goes back to normal. Then again it maybe because I did this. I let the touchpad run it self dry and shutdown from now power I put it back on the charger and let it get full power again. My after a while on the charger came back on so when it was funny charged it was back on. The battery is back to normal its been off the chargers since 530am its now 2pm which minor usage and its still at 100%....

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...
First off, picked up 2 GTabs yesterday and thanks for all of the work everyone has done to make these tablets better. And my first question of probably many.
Our Battery level indicators have not gotten back up to 100%. Yesterday when I was flashing the roms they would get to 97%, and after charging over night they showed 96%. Didn't know if there was a way to calibrate the level there or not.
Thanks.

I'm not sure if this will work but, if you can get into recovery mode:
Press and Hold down "Volume Up" Button and then press Power Button until you see a messege on the upper left hand corner that says something like.
"Detect a recovery Key pressed"
From the recovery menu, select ADAVNCED, then WIPE BATTERY STATS.
I've never had an issue with the battery on my GTAB but maybe it will help.
Good luck
That's very helpful, thanks! I was havng the 96%/97% maximum charge issue as well.
Running TNTLite 4.2.3.
Going to go ahead and drain the tabs down today and let them charge to full overnight one last time. If they still give me trouble I'll try the battery stats wipe.
Thanks.
I have the same thing happen to me after I flashed.
It only charges to 97%
I tried wiping the battery stats but it still only charges to 96/97
running vegan 5.1.1
I'm having the same issue. Hmm
VEGAn 1.00 beta 5.1.1
Hi everyone.
Had this exact same issue.
was using ZEAM for my launcher,
once I switched to Launcher Pro, my battery level now shows 100% when the charge light is green.
Not quite sure how this is related to ZEAM, but I used ZEAM for my launcher on both TNT and VEGAn Tab and had the battery level issue - would never charge past 96 or 97%.
hope this helps!
running launcher pro and vegan...still nothing past 97%...have wiped battery stats etc..
Mine only shows 96-97%, but actual battery life is excellent.
Success! Sort of. I'm experiencing the same issue, but I've been able to get the battery to display 100% but charging it up to full, unplugging and using for a few minutes and then plugging the tablet back in. This trick doesn't work every time but I have been able to get to 100% a few times. This expirement was performed on Vegan tab and Pershoot's February 18th kernel.
Weird... Mine is doing this too (vegan rom). My battery life is excellent but I'm still obsessing over that last 3%... At least its good to know is not just me.
Has anyone found a fix yet? I'll probably try draining the battery and charging it; we'll see what happens.

Corresponding values Volt-percent are hard coded in software (100% - 4.2V per cell).
Trying to top off your battery, charging circuit may malfunction and battery may be overcharged. Anything more then that and lipo (battery) will degrade chemistry very rapidly.
97% is about 4.15 - you are not losing much capacity, but your battery will hold much more cycles in a long term run.
Mine used to charge up to about 96%, now it never goes above 94%. I'll try wiping battery stats in CWM and see if that changes.
Not battery life.
Today i noticed my battery meter has been sticking, any way to fix that? It'll drop 20% upon reboot.
Today i noticed that my battery would spike up from 95% to 100% while charging and not go anywhere in between,. Is that normal? Battery calibration app kept going off early, and then as soon as it hit 100% i unplugged it without calibrating it, and it dropped to 99%. Happened twice in five minutes.
Also, instead of using clockwork recovery, i use Battery Calibration app to wipe my batt stats.
What mV should i be on?
One last thing, how do you bump charge? And is it really that unsafe?

I noticed this yesterday, I had my phone plugged in and it was at 94-95% and 2 minutes later it was at 100%.
To bump charge, once your phone is at 100%, unplug your phone power it down then replug it in. Once it shows the green LED meaning 100% charged boot your phone up and keep it plugged in. Might go back to being orange saying its not 100% yet so let it get to 100%. Unplug it and replug it back in a couple times until every time you plug it in it shows green for 100%.
I would think that it would be bad for the battery if you do this every day, but I can't give a definite answer for that. I use Battery Calibration to do that too, but between today and yesterday after I flashed over the new CDMA/LTE radio leak from the Radio thread my battery life hasn't been great. Considering going back to the stock radio.
I've noticed similar things on my bolt and even my dinc. To counteract this, I stopped looking at the battery % and got battery left instead. This app tells you how much longer your battery will last in hours rather than %. I no longer freak out about my battery life, %, or what others are getting; I've never been happier.

Sounds like a good idea especially for me lol. I noticed this morning that my phone was 56%, down from 74%. 18% drain over the time span of like 6-7 hours or so while I was sleeping. Not sure how good or bad that is, but for me it was just like wow.
You're being anal. Don't worry about it. Your phone is working fine. The battery level will appear to jump around a bit, especially when going on/off charger, or rebooting. Search around if you feel a need to know why.
I find that my Touchpad seems to lose quite a bit of battery while it's sleeping overnight, when compared to something like my Nook Color running CM7 n173. The Touchpad will lose 4-6% sleeping over 10 hours, and the Nook will be hard pressed to lose 2.
Is there something wrong with my battery, or a setting I should be changing (wifi and backup are off)? Or is this normal for Touchpad deep sleep?
are you saying you have wifi and backup off or asking if you should turn them off?
mine probably looses that much in that period of time with everything on and idling...
Yeah, they're both off when I leave it overnight.
Well my touchpad has been off my touchstone since 7 this morning, now 15:00. I have checked twitter, facebook and ebay about 4-5 times since then and my battery is on 100% . Thats with 3 programs running and WiFi on.
I can't give you on overnight figure as it sits in my touchstone
Does it really matter if you lose 4 to 6% in 10h overnight? As long as it doesn't drain at a stupid rate with wifi etc turned off and whilst doing nothing, surely there's nothing to get concerned about. Frankly, I have no idea how much battery mine loses sleeping, or doing anything else for that matter - I just use it, when the battery needs feeding I plug it in - drama over

why wouldn't you just turn it off then... or was this just an experiment to see what kind of battery life you're getting
With backup off and wifi on, OCed to 1.7ghz, my battery stays at 100% if I leave it off charge all night, around 7-8 hours.
Some moderate use throughout the day, and watching some YouTube videos before bed, wifi on and brightness up, mine easily lasts 2 days before needing a charge.
did a test... with backup and wifi on with 3 email accounts being pushed... unplugged and fully charged at 3pm... 9am this morning i'm at 75%... that's with some light usage as well... not bad for 18 hours
i'm over clocked at 1.7 with warthog kernal and have all the suggested patches installed to speed up performance...

Hmm...well, this is the second time that this has happened in the 2.5 weeks that I've owned this phone. I'm currently running unNamed ROM 1.2.0 and noticed that my battery is draining quicker than usual (8%-10% drain per hour on IDLE).
Usually, my battery drain is between 1% - 2% per hour on unNamed. What I've noticed in both the instances where my battery drains rapidly is that I end up seeing 'Core Apps' (white envelope with android icon in the middle) under the Battery Usage. From what I can recall about this icon, it's the icon for the launcher. CPUSpy shows my phone at 78% deep sleep (the phone's usually around 93% - 95% deep sleep when in idle).
The first time this happened, I was away from home on business for 1 night and ended up having to power my phone off when it got down to 11%. Got home later that day and recharged my battery while the phone was off and after the phone was 100% charged, it lasted 38 hours with 7% left before I powered off and recharged. Again, the battery with light usage lasted 30 hours with 30% left.
Today, after charging (while off - seems to charge better this way) I was surprised to see that my battery was draining at ~10% per hour and I saw that 'Core Apps' was listed under Battery Usage again.
Fortunately, I am not away on business this time (yeah, my spare charger is on the way) so I can recharge teh phone at home. Is the only way to "reset" the phone's battery usage history by pulling the battery or charging the phone?
Hopefully, one of the devs can answer or provide a fix/workaround for the 'Core Apps' drain? (BTW, I leave my WiFi on all the time and my phone still lasts anywhere between 28 hours to 40 hours...just wondering why I have these sporadic glitches when the battery doesn't seem to last long.)
From my experience... this will be very hard to fix. Usually appear ramdomly, and disappear randomly.

Yeah...the 1st time it happened, I was wondering "WTF is 'Core Apps'?"
Now that I've seen this the 2nd time, I'm stumped by it since you're right...it doesn't happen often and doesn't seem to be reproducible by any consistent method.
Hard to do a battery pull with this Neo Hybrid case (case is a PITA to remove) and I don't have my 2ndary charger yet...
Rebooting the phone does nothing since the battery history remains and even powering off for an hour and then powering the phone back on still doesn't clear out the battery history so the drain continues!
Oh well...it is what it is then I guess...I was hoping that someone smarter than I could find a way to cure this. (BetterBatteryStats doesn't show this as a wakelock (partial or full)...CPUSpy just that my deep sleep state is in the mid to upper 70% which isn't the norm.
Oh well, hopefully, this doesn't happen too often.

But a few have reported their phone doesn't behave right in reporting battery percentages after wiping battery stats.
Doesn't mean you can't. But no one has proven it helps.

I haven't had any issues that can't be directly linked to something else (like random reboots).
If all you want to do is reset your battery useage screen to zero it definitely does that. The point isn't to help anything, just to reset the screen to zero without having to wait for the phone to charge all the way.
In that case not a bad idea if you see it show up. If it's as bad of a battery drainer as it seems and still running, it should show up again pretty quick after you clear battery stats.
It'd be useful in reading the logs to know that at a certain time it was for sure running.

Dunno, it's just odd...recharged my phone last night and now I'm back to 1%-2% battery drain on idle and the phone's going back into deep sleep at 93% and I haven't touched any of my settings. I just let the phone dip to 19% and powered off and put it on the charger for ~4 hours (I know, I could've pulled it sooner since it wasn't at 0% but honestly, I forgot.)
It's just the weirdest thing...whenever Core Apps appears as the envelope w/Android icon it seems to be persistent and stays in the battery usage. However, there have been times when the Core Apps appears as teh same icon as 'Contacts' and will disappear on it's own after a while. <-- This seems to be okay as the battery drain remains minimal.
I'll have to check out Entropy's battery drain thread later to see if I can gain any insights. (Haven't ever flashed any of Entropy's kernels as standalones -- I've just been flashing unNamed ROM so I know the kernels are stable builds and not the experimentals.)
