Transformer Prime Main Battery not charging past 56% - Asus Eee Pad Transformer Prime

I have searched the forums and have not managed to find a solution to this problem. This started a few weeks ago with the tablet only charging to around 80% charge but over time it has slowly reduced to only around 50-60% (today 56%). I have 2 chargers which both have the same result. Both charge the keyboard to 100% and both charge the tablet up until the point the icon changes from charging to a normal battery indicator at only partial charge. I have tried resetting multiple ways and times and a full factory reset, to no avail. Any feedback / insight into the issue welcome.

Sounds like it needs a new battery.

You might be right. I was hoping there was some kind of misreporting issue. Something similar happened a few months ago but one day it just worked to full charge and was fine for a while. The intermittent nature had me wondering if there was a software issue.

Have you cycled it completely?

I didn't fully discharge the battery to zero and recharge if that is what you mean. I try to avoid it since a previous phone fully discharged and was a nightmare to get going again (sealed battery). I called the people I bought it from and they organised a RMA at a local store, so it is out of my hands for a while. Hopefully it comes back without any dings etc. and a working battery. Thanks for your input.

I know with android sometimes the fuel guage can go crazy, if it were, say, an S2 i'd say go to recovery, reset the battery stats and cycle the battery. If you FEEL the tablet is only lasting half the time it should then the battery may have issues. If it doesnt seem like your losing any play time just the guage is weird then ya i'd suggest playing with it till it shuts off and let it fully charge, sometimes android needs that just to calibrate the battery stats.
You never want to let these batteries discharge to complete 0 however most have a undercurrent protection where they shut down if theres too little power so damage doesnt occur. (My S2 actually stopped charging once when it got well below 0, i thought that was cool)
Anyways, good luck with the RMA, let us know how that goes!

It was definitely only lasting half the time it did when it was taking a full charge, so I think it is likely a battery issue. These things happen. Now it is just fingers crossed for the RMA.

Just got my RMA back and they have replaced the entire unit, which will hopefully do the job. Currently charging (totally flat on arrival) so patiently waiting to have a play. Forgot how much I like the form factor.

[Q] Battery Concern

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.

question about reconditioning battery

yesterday after flashing nero 5 i wanted to recondition, so while sleeping at night i charged my phone to 100, and now during the day time im trying to waste the battery, but during that i got caught up on adb and connected my charger, and left it there, now its back at 83% battery, does this mess up the reconditioning process? or do i have charge back to 100, then do it all over?
anyone? please lol

what you should do is drain it all the way untill you cant turn it on anymore and leave it chargin all night turned off, and when you wake up turn it on and let it charge untill its full again, then boot into recovery and wipe batt statt , and you should be good to go mine last about 20 hours after i did that

me to im near a power source or computer all the time so
What you should do is keep letting it drain until 1% or so. I don't think you need to let it die completely. Charge to 100%. Boot into recovery and clear battery stats with the charger still plugged in. This is the important part. Then drain the battery and charge to full. Then you should be good to go.
question, after draining to about 1%, does the phone have to be off? and can i use the phone just a bit while its charging?

The general consensus is that when you condition you should charge the phone while it's off. I don't know enough about battery chemistry to tell you why. Just do it to be safe
Battery "recondition", actually does not "recondition" the battery, it is a trick just to get more accuarte readings (that's the only reason you reset STATS)
The battery may not charge up to 100% and will never do, just following this procedure. It will just say it is @ 100% when you actually are @ 85 or 87, that's why the sudden "jump" you see.
Best way to try to get better readings is charging the battery till it says 100%, unplug it and plug it again a couple of times until it fully charges and follow the same procedure.
Once yo did this a few times, turn off phone, reboot in CWM (with the phone never unpluged) and clear battery stats. turn off phone and unplug,,,,
You will got at least more accurate readings

Android Police did a piece on plugging and unplugging your phone to get up to 100% (it's called bump charging, see below). They recommended that you NOT do it because it doesn't get you much additional juice and you wear your battery out faster. Normally I just charge my battery up to 100% (no drain), wipe the battery stats, unplug and go until it dies. I use it while it's plugged in and still get a full day easily out of my phone.

I hate to be the bearer of bad news. You can not condition a Lithium-Ion battery. All you are doing is wearing it out prematurely by deep cycling. Every time you do this you destroy your over all battery life a little.
I have posted about this here in several thread, and I am getting a little tired of having to tell people NOT to do this because they don't search for themselves. Do a search on the forums for deep cycle li-ion and see for yourself.
If you want to know the technical reasons why, Google is your friend.
so we just deal with what is perceived as faster battery depletion?
Im asking because As i have posted on another threat I am a complete freak about my battery life.
Basically yes, I have 3 batteries to go around all day, although I us the car charger, if for any reason one day I take the train to the city, I will eat up 2 and a half batteries in a day.......
I had 3 batterys for my hd2 I need to get 2 new batteries for my vibrant. I guess im just tripping because I tried and over clock kernal and it seems like its dying faster while the screen is off

Yea, just chill. It is all in your head. From ROM to ROM, usage pattern to usage pattern, and app version to app version - there are just too many variables to worry about. Just use your phone, charge it when it needs it, and relax.
Your phone's battery is going to get less life as it ages. There is nothing you can do about that. Also, it will likely only get 2-3 years before it needs replacement. If it gets less than 2 years it is because you have been "conditioning" it. which ages it prematurely and also causes how long it lasts between charges to shorten as well.
Li-ion does not have a memory, so conditioning is an inherently false concept. Recalibrating the devices ability to read the battery is a different story, but it should only be done if it really needs it (like it thinks it is at 1% when it is at 20%), and it should never be done more frequently than a minimum of 30 charge cycles or if you charge it once a day when you go to bed no more than once a month. Less frequent is better.
So sorry, you need to find something else to obsess about. Might I suggest getting Team Whiskey to make BlackFroyo the default theme, use the 5 bar signal meter, the larger numbers on the battery, and the hacked camera the used the power button to take pictures. That would save all of us some time.

Nice link - try reading the stuff by the engineers that work with batteries for a living now instead. You do know eHow is just a site where any idiot that thinks they know something can post, right? Are you going to reference wikipedia next?
BTW when you recalibrated your battery and got 6 more hours, did you do anything else that might have explained it? You know like flash a new effing ROM? That might possible change a few things to do with your power usage.

it was a joke
and no, i flashed Nero 4.1, and then used it for a week thinking the phone would adjust to the battery and new rom, it didn't.
then i thought i'd just take a chance and recondition my battery, it was my first time, and it worked out great.
and trust me i'm a heavy user.
roughly 300-400 texts per day.
20-40 phone calls
music about 5 hours per day
and i play soem games, but thats understandable because playing dungeon defenders uses like 30% battery per hour bcz of the high graphics and such.
a bunch of app downloading.

[Q] Battery Level Drains Inconsistently

I tried searching this in a number of places. I couldn't find what I was looking for, although it didn't help I had trouble using the right words to search for it with, but here goes.
I'm running CleanROM Reborn 1.1, I love it! Other info is also in my signature. Once I turned on the percentage number for my battery level, I really started to notice this.
The number will stay at a number for awhile sometimes, even when I use it, then other times it will jump several points within a minute. It doesn't drain consistently. Anyone have any insight or suggestions? It's more annoying than anything else. My battery life is alright.
I would've tried wiping battery stats, but I hear that doesn't really do anything.
Thanks.
download Battery Calibration from the Google Play Store, then charge your phone to %100. open the Battery Calibration app and calibrate it. There is also instructions inside the App if my instructions are unclear
Im going to try this but for some reason mine only go to about 96%. Never 100% lately so I am not sure if I should do it then or just leave it charged until it is 100% and hope it gets there.

Not to hijack the thread, but the phone is designed to fully charge and then discharge to 95% and then charge to 100% again, rinse, and repeat. This is to keep the battery from becoming destroyed by overcharging. Maybe that's what you are seeing, Bambino.

I've noticed this too on Ics leak roms. It sips power with screen off, then drains quickly when on sometimes and hardly at all other times. Mine just sat at 82% for the past 20 minutes, then dropped to 76% over the past five. I've heard battery calibration is bunk, but I'll try the previously mentioned app and see.
Some roms do not use a percentage because they are so inaccurate and cause the user to obsess

A little info on batteries
The important thing to remember about Lithium Ion batteries is that when you do charge them, bring them up to full charge before taking them off the charger.
They all have a circuit board in them that remembers a full charge. (If you've every taken one apart you'd see this) When you charge them this chip will restore the amount of power that has drained.
Partially charging them will screw up this function. And screw up the battery.
Deep Cycling is good for them but not all the time. Once a month is good for them.
A good rule of thumb, but not absolutely necessary is to discharge them 50% and then bring them up to a full charge. Obviously this is not always possible when playing video games or watching movies. I always try to leave it on the charger when watching movies in the cradle.
There is an app on the Market called Battery Repair. It makes an attempt to reset this chip on the battery by meticulous monitoring the charge and capacity left in the battery. Running diagnostics and setting the battery to its best state. Its the only one out there that does this.
Battery Calibration app is good if you change roms or batteries alot.
Here is what it does:
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
The app shows your actual battery status, and only allows you to start the calibration (i.e. removes the file) when it's fully charged, unless you force earlier calibration.
The voltage meter can be useful too. Full charge is around 4200mV.

[Q] Uneven battery drain

Hey guys,
So I've been using my Z2 quite much in the past few days and I've noticed some kind of a strange pattern. After I plug my charger out, the battery percentage goes from 100 to 90 in like 20 minutes. It keeps dropping at this pace until it reaches around 40%. Then it slows down to about 3-4% in those same 20 minutes and basically keeps this pace until death. The usage is pretty much the same and I don't understand where this might be coming from. Is it possible that the battery is somehow uncalibrated?
To be honest I'm no expert with this topic, but I know with my old phone (Samsung Galaxy S3), battery calibration was a myth. People bought into it and played it up as if there was truth to it but in the end, it was all bs. For Sony devices I'm not sure. The one thing I may recommend (which might not even do a thing) is charge your phone to 100%. Then without unplugging the charger, load up the dialer app. Type *#*#SERVICE#*#* to access the service menu. From there, click on service info, then factory charging. Not sure if that resets any sort of battery info or anything but it's worth a shot.
as far as i know it calibrates on the hardware side
charging to 100% and then using normally till 0% and cycling this quite a few times will actualy balance out the battery in most xperias

Possible Solutions for the Nexus 10, 0% battery issue

Okay I just had this issue on my N10, but I solved it by switching the charger out (yes sounds stupid, but it helped)
I did have this problem on other tablets however and I am happy to share the solutions I have found over the years.
Solution 1: Battery stats.
Plug it in and boot into twrp. If it just keeps showing a faint white battery icon, use solution 2. Now max out the screen brightness, and let it die. Now plug it in and charge it to 100%, boot into the OS and calibrate the battery by wiping the battery stats or grabbing a battery calibration app off the play store.
Solution 2: Different charger/Wall Brick
This was my N10s issue, I tried solution 1 but that didn't help, so I tried switching out the wall brick. I traded my 5 Watt amazon adapter for a generic usb wall brick. My wall brick heats up, yours might not. You know that the charger is a problem when you plug it in and the battery icon is dim, it should be full brightness and doing a little charging animation. I noticed that this generic brick would do the animation so I tried just leaving it plugged into that, and my tablet is now at 7% and going up slowly.
Solution 3: Reboot over and over again
Exactly the title. On my old kindle, the battery would occasionally come up with a real number rather than 0%.
Solution 4: Rom cycling
Flashing a different rom. I had to do this on my old tablet a few times, but it would fix it sometimes. Honestly any rom will do, just keep cycling.
Solution 5: Replace the battery
Lastly you could just replace the battery. a battery is about 40$ on amazon, so this is a bit pricey. This is a last resort and will most likely fix your problem, and if it doesn't, you'll at least have a nice full battery for when you do. I've never done this, but I've read about people having success when they do.
Tried most of the items you pointed out and unfortunately changing the battery was my only success.
However the new battery is also starting to give away. Using it as a photo frame so battery is not a issue, the yellowing of the screen however is..

'ole N10 user here, ordered a $23 replacement battery just now then hoping it resolves basically a dead battery. I own lots of tablets but a "why not" feeling if $23 makes it as-new.

I can confirm that there is something strange going on on the nexus 10 hardware. When I received my second hand nexus 10 ,it shoots down at 40% . Now after 3 months, I don't know why but trying to charge in twrp, let it go drain all the battery in twrp, and charging when it's turned off completely recovered the charging hardware ,because I know the battery can't recover from a bad state . Now it turns off at 0% , and it's not only a calibration effect, it lasts longer than before. I charged mine with an aukey charger and some good quality cables . I never used the original wall charger , because the aukey has 5 connectors and I use it to charge all my devices

I fixed it, turns out it was the charger I was using. Guess I was lucky, my Nexus 10 is a champ now.
I fitted my Nexus 10 battery. Bought the battery [URL="https://www.youtube.com/watch?v=yru4k62qdEU"]here[/URL] and used this video guide. It was very easy took me about 30m watching and re-watching the key steps, the ribbons being the one to pay particular attention. Wow, though 17 screws......
I have Android N via Pure Nexus unofficial build and its performing well. Its relatively slow cpu by today's standards does make it stutter more if I make it do a few things at once, relative to my Pixel C, but I love the forward speakers and good now for a spare tablet. I just did similar thing for my Nexus 7 2013.
The Pogo pins is finnicky takes a few connection attempts til it works. I can see why 2 models later (after Nexus 10 was 9 then Pixel C) they moved to USB-C 3A 5V 15W its far quicker.
I've replaced the battery, changed a few roms, use different chargers all the time (whichever is Handy), and tried resetting the battery stats. No joy so far. Always shuts down at 30%.

I had the same issue with a new battery. I charged it up to 100% then went into twrp (I'm running linage) and wiped the cache. Touch wood it seems fixed.
I'm having a good experience once I opened up my N10 and replaced the battery. I'm getting very good battery life, on full brightness about 8-9 hours.
I like the screen form factor for watching videos like MP4 or Netflix. It is so good I turned off my Pixel C at 60% charge to make its $600 expense I spent 18 months ago last as long as possible for when I need its performance which is when traveling.
The recharge performance is the biggest weakness, I have to plug in the Pogo cable and leave it alone. I have a bit of light bleed on bottom right corner. Audio via built in speaker is a bit feeble. Running Pure Nexus which eventually will get Oreo.
I bought my Nexus 10 when released. Battery still lasts till the end and charges fine to 100%.
But this screen is so bright, I always kept it at lowest brightness. No screen issues and no battery issues and use it everyday since new.
I bought my Nexus 10 the week it was released. The battery eventually stopped holding a charge, and I replaced it. Now my battery indicator is stuck at 100%, which is as bad as 0%.
I'm about to try a different ROM. Hopefully that will help.

Fully charge it, wipe battery stats, reboot
This is a common problem when swapping batteries on any device. It took me a while to respond because MeowDude is my old account.

I tried letting the battery drain until it shut down, then recharging to 100%. I think it's better - not sure.
How do I wipe the battery stats?

Last year my Nexus 10 was due for a new battery. I swapped it for a new genuine one, but since that day the Nexus will shut down at around 80% charge. It's not that this percentage is incorrect (it happens at around two hours of light use), but it somehow sees 80% as 'empty' and shuts down. I've tried all solutions mentioned in this thread but to no avail. Any ideas?

Since I replaced my battery, my Nexus 10 stays charged for days. If you've replaced the ROM (so you know it's not a software problem), then it must be a hardware problem. Hopefully you just got a bad battery, and it's not the Nexus 10 itself.
