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...
This morning went into battery saver to see the estimate of battery life when I unplug and noticed that the phone stopped charging at 96%. It was charging the whole night. Unplugged. Waited. Plugged it in again but it sat there at 96% and not charging any further.
I noticed the same after updating to latest firmware yesterday (11500). Though I still get more charge than before the update. But the last 4% wont charge for some reason although the battery indicator shows as full when the phone says its fully charged.
Probably not an issue, Samsung often do it on purpose.
I don't believe it's an issue either. At least I do not worry about it. It's just a number that doesn't impact the phones functionality.
I´m spanish, just in case you want to answer to me in castellano . I also had the same issue. When i charged it the second time, it reached 100 %, but full charge capacity lowered to 1380 mAh.
In that ocassion the battery was depleted in 11 hours with a high discharging rate. Strange thing is that today when I charged it for the third time discharge rate is low again, something around 120 mAh and the battery´s life expectancy is back again to normal (27 hours or so).
Anyway, the full capacity is still around 1380 mAh. I say around because the number changes by the day.
Saludos.
Yes, running 11500 and only noticed it today. The other day when I actually checked battery saver in the morning it was at 100% and 1 day 3 hours remaining with 1517 mAh full capacity ... today, as I mentioned, 96% and just 23 hours remaining at 1470 mAh full capacity. It appears that there is still something screwy with the battery. The phone does last longer than before however.
Had similar issues with HTC Desire back in the days when it wouldn't charge to 100% required full discharge or battery recalibration.
Now mine charges up to 100%. It was just the first charge after update that went up to 96% only.
The maximum charge capacity fluctates from time to time. Nothing to worry about it just does that I assume.
What is det estimatet time remaining after charging 100%?
Around 1 day and 15 hours.
I have the same issue! I left the phone charging the whole night, the morging after the battery charge indicator was 100%, but as soon as i un-plug the usb charging cable it fall back to 97%!
I suggest you to use the nokia diagnostic app to see the charging percentage of the battery, in my case is never up 97%. I think It's a WP7 bug...
The bug isn't that big.
I've had mine stuck on 45% for a while, that was really annoying
i am havin HTC AMAZE 4G
when i used to charge it before
phone used to come to 90% from a full in approximately 1 hour.
now it comes very quickly like 10-15 minutes
& also the major problem is my phone gets switched off at any battery percentage like 65% & when it gets restarted it comes to around 8% or sometimes even 4%.
if i pull out battery again restart the phone then sometimes it comes to around 30% back or any random increase in battery or sometimes even decreases to 4% & then the battery gets drained in 5 minutes & i have charge it again
battery takes more time to even charge
sometimes using DATA & charging it even takes 10 hours to charge
i dont know what is the problem
i have been thinking about battery problems
but i googled & in some blogs it shows as circuit problems too
the problem is i am living in INDIA
this phone is not official here so the service center guy wont touch it & i dont want to waste money on the battery if it isnt the problem
USING HTC ICS OFFICIAL ROM
NOW BATTERY LASTS with normal data on maximum 4 hours
help me out guys
thank u
How old is your handset? Battery life decline is normal as it ages. Without being able to inspect and test yours out all I can tell you is the most likely explanation for what you're describing is battery wear.
The original HTC battery that came with my phone only holds 2/3 of the charge it once had when new, which is why I invested in a pair of Anker batteries and an external charging station (I purchased them together in a package on eBay for under $30 US shipped). Having the extra batteries has been an excellent addition. I alternate them every few days to more evenly balance how they are wearing and to prolong the remaining life of my original battery. Plus it's great to have an extra battery to use for those times when I really need my device, but don't have the ability to plug in.
Check out the best battery thread in the Amaze accessory section for more details and comparisons.
I hav been using this phone for 1.5 years
tried using battery of my dad he uses same phone.
It showed 56% in my fathers phone
Wen i switched the battery &; started my phone it showed 15% at start
So what could be the problem then?

You're getting the different results because the batteries aren't calibrated to each phone. If you put your fully charged battery in your father's phone it shows 56%, correct? What happens when you put your father's fully charged battery in your phone? Keep in mind that when switching around the batteries neither with be calibrated to the device, but will instead show a percentage vs the battery that was properly calibrated.
Example: the battery in my phone shows as fully charged, but is worn and no longer charges to the maximum. If I place it in my brother's Evo 3D which uses the same size battery but is newer. It will show as only partially charged because his device is calibrated to his newer stronger battery. Conversely, if I put his newer battery in my phone which has been calibrated to my older worn battery it will appear to be fully or nearly fully charged for a long time before it begins to show it's draining with use.
The only way to properly test your battery would be to either try a known stronger one in yours for several charge - discharge cycles as your phone calibrates to it, or to try your battery in another device for several such cycles. Then you need to compare if there was an improvement in up-time or not. Short of taking it in to be checked on diagnostic equipment it's the best method I can think of.
Good luck!
Thank you very much for the reply
Goin to a local mobile repair guy for a hardware check
Will tell you the results tommorow
Thanks once again
Maybe you just need to wipe battery stats. One trick that works is let it drain completly and let it be drain over night and charge it again keep doing a couple of days it may just get better. But think is just battery problem not hardware related.
My Original HTC battery worked its way down to 2 hours of usable talk time. Eventually, got so bad that it barely charged on anything but a high current wall charger. Technically it was under warranty at the time...
Ordered 2 Anker Batteries w/ charger for $30, and not long after that the charger broke. It quit charging batteries.
I then just stuck with one Anker battery in my phone and the other as backup. The battery I used the most is now down to about 4 hours of life on a full charge. The least used is about 8. I try to keep the worse one charged up as a backup in a pinch and now use the good battery full time.
Just how life goes sometimes...

Yeah that Anker charger is the weak-spot in that 2 battery package deal. The damn thing is flimsy and fragile. I'm so paranoid about breaking it I treat it with kid gloves. The batteries are pretty good though. The package was one of the best investments I made since owning the Amaze. Using indelible marker I labeled them 1 and 2, and rotate their usage with my original HTC (which is easy to distinguish). This way when I'm on the road I always have one fully charged spare handy, one charging at home, and one in my handset.

Agreed!
But When I was using official ICS from T-mobile, I had the same problem, even after wiping. I even faced a funny thing. Percentage of battery in bar was different from percentage shown in lock screen!!!
After flashing custom rom, All problems GONE!
Last night the phone had 20 something, usually uses 4% per night, this morning 0, no battery OFF
I have been using MPJ battery without problems so far, it takes more charge than the original and lasts longer
2 hours charging, only 28%, something is wrong, I will take a spare battery when I go out, later will try with original to see if the problem is the battery or the phone...

The cable was not connected during the night, when it discharged, any way now it seems ok, only lost 2% in about 5 hours, no use ither than checking the time and battery load
But there is a bad contact on the USB plug, sometimes I have to fiddle with it to get contact...
HELP
Again, this time stranger, no apps on battery usage, but battery was discharging faster than usual and died at 7 am with a beep that awakened me, with still over 20% charge
-First screenshot, it died sometime the previous night, so I charged to 30%, then nothing showing, but kept the 30% charge until I charge it again around 16:00.
-Second screenshot, it has "blanks" on the chart, never noticed that before.
-Third screenshot, using more than usual during the night, it uses between 3% and 5%, and at 20% it just dies, now I put back the original battery to test, but it seems to be using more than usual
people should know MPJ battery's is trash, isnt worth the money because some weeks after they will be worst and worst!! i personnaly prefer to buy a original battery as a spare one, they are cheap now, with 19€ in LG spares site you can buy one or two and swap them, is easy, and buy a external charger from ebay or something (because LG spares site dont have that on sale i dont know why).
i will buy the external charger and one or two spare battery's soon because my battery is discharging too fast, now with 2h of videocall in skype my phone goes from 100 to 46 quickly. in the first two months i have almost 6h SoT and now i cant go longer than 4h.

The MPJ was offered to me for free to do a test, it was fine until now, I am not yet sure if it is the battery, will let you know when I am sure
By the way Android OS battery use is way down with the original battery

the MPJ battery's degradate with time, the real mah's decrease every charge. - i know what i say because i use one with my G3 almost 1 year ago and the battery is really worst than the original one!
one usefull app to have to know when your phone is 100% charge with the real mah's count is AccuBattery from playstore, there you find the real capacity of battery as welll their health...
you never should unplug the phone when the 100% pop-up shows full charged, you need to keep it from more one hour to get the full mah's and a good charge, i do this all the time and get some good battery with the original.
LG's battery isnt the best in the world but is better than MPJ for sure, i dont want a brick but if i need a excelent battery ZeroLemon 9000mah is a excelent battery, unfortunnaly they dont do the standard capacity 3000 mah for V10 only the 9000 mah...but this turn the phone is a heavy weight brick.
- see my yesterday - today full charge screens, for me is good enough!!!
P.S: The skype time is all in videocall. idk why details show only 47 minutes of camera usage!!!
In the garbage
Everything seems to be working fine with the original battery, MPJ in the garbage where it belongs, wont risk testing again
Even the "bad contact on the USB plug" was the battery failing
I was interested in seeing what my charge times were using the official charger and cable so using accubattery i checked the charge logs ranging from 10-40% to 100% and they were longer than what the guidelines stated. Phone did state that supercharging was active, had two thunderbolts on battery as well as the bubble animation (i wish this could stay on permanent )
When i bought the phone, charging from 20% to 100% took 1h 50m
and then in about a months time...
Charging from 10% to 100% took 2h 34m
Charging from 32% to 100% took 2h 11m
These were all with screen off, do not disturb turned on and wifi on. The charging time is not THAT big of a deal as i'm always charging it at night but i'd like to actually recieve the speeds that were promised. Using ampere i never saw the current surpassing 2000mah sub 10% (i don't expect it to supercharge as the battery is nearly getting to 100% in order to prolong the longevity of the battery) and they would fluctuate down to 600-700mah a lot of the time.
So i contacted huawei support and the advisor agreed that the charge times i told him were longer than they should be so i've sent my charger (along with the cable) for repair. It's currently at their repair centre so i've not had a diagnosis yet on what the problem is, it could be the phone having issues for all i know!
I wanted to know if anyone else has been keeping stats on their charge times and whether you are getting times similar to me or slower/faster, would be interested to hear!
Do you have the double lightning symbol? If not, turn off your charger for about a minute and try again?

Difficult to say if there's any hardware issues, the repair centre will find it if there is one though.
Your charging times do seem a little high but its also difficult to compare a new phone to one that's been in use for a while, as there will be more apps running and drawing power etc than on a clean phone. Over 90% charge the charging rate will drop as you said, but that's not the only thing to affect it, temperature has a big impact...hotter charges slower.
Measuring mAh on the phone is therefore only a guide and shouldn't be used to prove slow charging etc. (e.g. if I have my satnav app, bluetooth & mobile data all on, then even using my supercharger, the charging rate shown by the phone sometimes drops to under 400mAh and even into negative figures if the phone is hot)
0% to 100% should be about 90mins in perfect conditions, but I'd be surprised if anyone got regularly near that sort of timing.
Got my charger back 2 days ago and today i deliberatly ran my battery down to 9% to see how charging would go. For the first time since recieving my charger back i've gotten a steady 4000mah. 9% to 72% (+2400mah) took 55m which is much better than the 2hours+ it took last time to get a +2600mah charge before. So yeah, if you're noticing similar speeds, contact huawei and see if you can send it in!
Mine charges from 18% to 100% in just an hour and 10 minutes.
