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...
So I have just flashed the CM7 ICS Themed BETA, wiping everything.
I then charged to 100 percent, and used Battery Calibration app.
I have just setup some apps, and I have lost 10% battery life in 40 minutes
Display is using 85% battery life apparently.
Please help?
It can take up to a week to fully calibrate the battery. Since the battery doesn't have memory the phone has to get a feel for how much juice it actually has. Try it for a few days running the battery down and then charging it to full without unplugging. If that doesn't work you might want to try charging all the way then reflashing and immediately do a calibration.

Yeah, I'd calibrate the battery - wouldn't hurt.
Ideally always flash on a 100 % full battery to avoid problems like yours..

Cheers guys I've taken this all on board.
I'm on 13hrs on battery, its showing 16pc. Battery calibration app shows 3609mv however. This doesn't seem right to me. Am I correct in assuming the phones battery power is the mv listed and no battery is more like 100mv??
Could anyone explain the 'mv' term to me?
Is 0mv when it powers down? Is this indicative of power?
Thanks.
Lithium ion batteries never fully discharge. If they did the battery would not recharge again.
Sent from my MB860 using xda premium
mv referers to mV, as in Milivolt. Most li-ion batteries are rated at 3.7V or 3700mV. A nominal full charge should be around 4.2V or 4200mV.

That's 35 minutes of active use. 10% isn't outside the realm of the possible.
I usually can go a full day on 60% battery, but this morning Facebook, the interwebs and text messaging put me from 100% to 77% in the course of 30 minutes. Draining 10% in 45 minutes does not seem out of the realm of possibility
I get mine to last around 20-26 hrs on a single charge, of course depending on use. but i hardly leave the house and dont use it a whole lot. One thing to make sure of is setting up profiles on SetCPU and/or undervolting. i just posted my setup on another thread. http://forum.xda-developers.com/showpost.php?p=20284361&postcount=28
so after you clicked the battery calibration button and it said calibration successful, you're wondering why the battery is dropping so fast under use right away?
Easy answer my friend, when you first use the battery calibration app, the first cycle (when phone is being used) will always drain a lot faster than the 2nd and 3rd time around.
The battery calibration app, wipes the battery stats, and makes a new one, however that does take at least 1 - 2 times of a full charge/discharge of the battery. There is a battery tread in the atrix general forum i believe for cailbration steps, etc to go about successfully doing a complete calibration when flashing from rom to rom.
Hope this helped
Hmm, maybe I am just upset that I have to charge every night.
Coming from a BlackBerry 9780 I could go 2 days with semi-heavy use.
I am now using the official Motorola cable, and only charging from very low to full.
Thank you for the advice.

Try getting one of these:
4800mah extended battery
1900mah extended battery
Problem Solved.
Bluetooth radio was killing my battery. WiFi is fine leaving it on as it disables in stand by, but bluetooth was absolutely draining everything.
thanks for the update
I agree, 10% loss in 40 minutes of active usage is not bad. If the OP had better battery life before he flashed to new ICS themed CM7 beta rom, maybe the new rom is to blame??? I'd OC/UV, possibly with the latest faux123 kernel.

Thanks for the tip!!!
I've bought a new legit/official (has holo, serials etc.) Atrix battery.
Charged it to 100%.
During usage, its draining literally 10% an hour with very light usage (several minutes an hour). In short its draining at three times the speed of my 1 year old battery.
I've tried wiping battery stats but that didn't work.
Any ideas, or is the stats just buggered and I just gotta run it in? (ie it will go to zero then sit on zero for 5-6 hours lol)
note I've gone back to my original battery in meantime rofl
EDIT: The actual problem is that the batt is reporting much less capacity than it actually has
|The new battery is great capacity wise lasts till midnight
However the stats are still totally screwed, it will say 1% by midday, then hum along until midnight fixed at 1% (I dunno exactly how long for as I can't take the risk of leaving it off at night then its dead and I don't wake up for work in morning). |
Could just be a bad battery. Considering the old works fine that's probably the problem.

I have a similar problem with the original battery that came with phone it drains the charge quickly to 1% and on one 1% it gives a battery life of more time than the time it took to discharge from 100%.i was thinking of buying a new battery but now i am confused that what should i look before buying the battery to get a battery that can show me the exact charge on the indicator.
I have tried all tutorial of calibration used different roms and kernels but nothing seems to solve the issue.
well I might try that then, just let it run to zero see how long it lasts then see whether the stats come good over time
OK help needed.
The new battery is great capacity wise, lasts from morning to bedtime with >2 hours of bluetooth music, 30 mins calls, a ton of texts.
However the stats are still totally screwed, it will say 1% by midday, then hum along until midnight fixed at 1% (I dunno exactly how long for as I can't take the risk of leaving it off at night then its dead and I don't wake up for work in morning).
Aside from wiping stats which I have tried, is there anythnig else I can do?
I really want to use it, like I said real life capacity is great, but if its always giong to be reporting 1% its a bit dicey not knowing how much batt you really have left...
same issue with my spare battery not sure wtf is going on
When I have battery stat problems the following has always fixed it:
1) leave phone on until it dies
2) take back off phone and plug into wall charger
3) after batt symbol shows 100% (without unplugging or turning off the phone) remove the battery. After a minute or so battery symbol will have question mark
4) put battery back in and leave it for at least 2 hours (seems like I have had to press the switch sometimes but you don't want the phone to reboot or you will have to start all over)
5) reboot into CWM and wipe the battery stats
6) reboot and it should be good to go
Anyone else found a fix to this yet?
I'm now running ICS (turl build) issue is still there.
Steps taken to resolve
- discharge to zero
- charge to max
- wipe stats
still there.
The weird thing is that the actual capacity is fine, it can last all day no worries, just from midday onwards it thinks its 1% so has annoying LED flashing at you, also you have no idea how much batt it actually has.
Edit: I just realised your suggestion above has extra step (take batt out of connected atrix then insert again). I guess I'll have to drain it again and do it overnight... gah

Nothing will work i have tried almost every tutorial. Recently i found out the phone is showing the the full capacity of battery only 500 that's why i think we will have to change that with the actual voltage to get a accurate battery indicator.What's ur battery full charge design check if from the root exploler
/sys/devices/platform/cpap_battery/power_supply/battery
My phone uevent is showing this
Powersupply-capacity=5
Powersupply-voltage-now=3836000
Powersupply-temp=260
Powersupply-charge-fill-design=500
Powersupply-charge-counter=1

I'll try the insert empty bat into already connected phone, charge to 100% remaining off, repeat trick overnight, then report back.
FWIW on my 'good' battery which is 1 year old ROFL it says 1880
not sure how changing it would help though or is even possible?. It must be dynamically reported somehow as my good battery gives me a 'good' stat.
I use battery calibration and it worked, have it

the battery is charging calibration if you have to load it to calibrate

500 same as you! second drain and calibrate did nothing
Maybe theres a faulty batch of batteries and we both got one
Can people PLEASE stop telling us to calibrate we've BOTH DONE THAT MANY TIMES NOW. The problem is that the capacity of the battery is being reported as 500mah not 1930 or whatever its supposed to be. THe actual running time of the battery is fantastic, just thinks its at 0 all the time lol
/sys/devices/platform/cpap_battery/power_supply/battery
Powersupply-charge-fill-design=500 - should be ~1900mah

,this is how i calibrate my battery,before i have 45min of standby it will decrease from 100% to 99% but now it is 2hours & 34min before it go from 100% to 99%,i felt the drain after 2 weeks of overusing my phone (1week playing paladog and 1 week flashing different roms,kernels and theming my phone with different launchers),
- Charge your phone to 100% while it’s on.
- Unplug it from the charger, power off, then charge for 15 minutes with it in a powered off state.
- Unplug charger from phone. Power it on, and then charge 15 minutes while the phone is on.
- Calibrate battery using battery calibration by NéMa then unplug charger reboot.
- Power on, charge for 15 minutes then unplug.
- Finished.
note: deleting battery stats(calibrating) don't increase your batterylife said by others and it is just a placeboo and i believe in them,but it fix my battery drain so why don't we give it a try,there is nothing to lose,battery drain is so annoying.
,thanks to NéMa for the awesome apps,
,thanks to jgezau for his thread as my reference,

That was from LEWA OS, one of the best rom at that time...:good:
First and foremost, a Google engineer debunked the idea that batterystats.bin has anything to do with how the phone charges. By deleting it, you're actually inconveniencing yourself, as there will be a short period in which you won't have accurate stats.
Secondly, the O1 has a lithium ion battery. Lithium ion and lithium polymer batteries don't need to be calibrated, as they have no "memory" effect (you can read more on that here).
Moreover, these batteries have built in charge circuits that protect and regulate the battery. Ever wonder how the phone knows the battery temperature? It's pulling it off the charge circuit. That same circuit also prevents the battery from ever being overcharged or discharged fully, which is why that convoluted guide about calibrating your battery by draining it to "empty" and then recharging it to full doesn't work. Worse yet, intentionally draining your battery is actually counter-intuitive, as lithium-based cells wear more as their percentage of discharge increases (you'd be hurting the battery in your effort to calibrate it).
Your instructions aren't detrimental, so if it works for you, go for it. However, based on my understanding of these batteries, it seems to me that this procedure is inconsequential.
Besides, a new battery for the O1 is only $6 USD on Amazon or Ebay.
I decided to replace my 2+ year old Atrix battery with an OEM battery. Since then I can charge to 100% just fine (ran the battery fixing apps and did a wipe battery cache thing) but the battery discharges visibly, like down 4% for a single google search, and gets stuck at 1% for many hours. I used an app to see the voltage and it tops out at 4.2v and levels out at I think 3.5v and dies around 3.2-3v if I remember correctly. Anyway, I just don't know how long the phone will last but it is lasting most of the day. Even turning setcpu off I run for hours with a battery drain app and stay at 1%.
Using MROM-1-0.20120505-olympus. I think this is still considered CM7.
Kernel 2.6.32.59-MB860-MROM-ga43d614.
I dont see your question...
Any way I think you need a few charge-discharge cycles to make your battery statistics work.

Okay, the question is what can I do to make the drop more linear rather than going from 100 to 1 in an hour and staying at 1 the rest of the day.
And I've charged discharged half a dozen times with no change.
As you have tried, I don't have better ideas.
I like checking the voltage reading, rather than the percentage value. It usually makes more sense above 3.6V.
Delete all files (or even better copy somewhere for backup) in /data/battd/. Turn off your phone, charge it few hours after led become green, remove battery with charger connected, wait for "?", place battery again and charge it for about 1 hour, turn phone on with charger connected, check battery level, wait to 4200mV and 100%, finally disconect charger. Use phone without recharging until it turn itself off or reach 1%. Then charge it and use normally.
I did it with new battery and now works great, charge to 4200mV, 100% and discharge to 1%

I have the EXACT same problem as original poster, and i see my battery dying to 1% within couple of hours, and then remaining on 1% for rest of the day! This is misleading and most of time i have no idea how much more my phone will go on. All this despite the fact that i bought my battery paying 35 bucks to get it directly from Amazon!
Tried doing what Zeljko1234 has said in his post above, but to no avail. The problem remains as it is. Anybody else faced this issue and found a resolution? Will hard reset or rooting help? Appreciate any help
