Hey guys,
I have a completely stock N8013. Recently, I've been charging the device but the % indicator stays the same even if charged for 10+ hours. I'm now down to 7%. I downloaded Ampere and I tried plugging into the wall socket and got around 1400mA, while on my laptop I got around 900mA, so I think the brick+cable are working. I also downloaded Repair Battery which IDed that about 5% of my cells were "bad" but it "fixed" that. Any ideas?
Drain battery to 10% .
Fully charge remove lead two hours later connect lead and recharge .
Download and run Battery Calibration app .( it does not calibrate just clears the battery stats )
Thats all you can do failure = new battery .

hello,
I started charging my tab, it got charged till 99% and then i kept on charging it but it didnt went above 99% so i thought may be its because i am using the cell. So i switched it off and kept on charging , The battry icon was charging towards the end part (like the last 10% is getting charged) but in brownish yellow collor (sort of dark orange color) i kept it for charging in this way for like an hour.. Still when i turned on the tab, its 99%. Why so??
I havent rooted it yet! its total stock..
Bought it just 5 days ago..
About half the time, my tab will only go to 99%. Since it's only1% I've never given much thought to it, but I do experience the same problem from time to time.

after reaching to 99%. How long does your tab works??? Are you using p3100 too??

I'm using a p3113. I've never noticed much difference in how long it lasts. Most days, my tablet will last all day whether it charges to 99% or 100%. You really shouldn't see any difference to speak of between a 100% charge and a 99% charge. I personally think it's an overcharge feature to keep it from overcharging. I've actually seen it jump from 100% to 99% one time. If that's the case, then it's a good thing. You could try to bump charge it like I've done to cellphones that won't fully charge. I really wouldn't recommend it since 1% is practically nothing.
Charge it up (powered on) until it's finished.
Unplug it, and turn it off
Plug it back in to charge (still powered off) again, until it says it's finished.It will continue to charge now.
Now unplug it and turn it back on.
Plug the charger back in (powered on) and charge until it says it's finished.
Keep doing this until when you have it powered on, it should say 100%.

The battery charging end is defined with two parmeters: the battery voltage reach a voltage close to 4.2 V and the battery charging current gets under 200mA ( a value I have estimated on my 5110 model) .
If for some reasons the residual current do not get under this limit value ( # 200mA) while the maximum battery voltage is reached , the state of charge stay screened at 99% !!!!!
The 4.2V battery voltage is a safety limit that a Li-Ion battery should not exceed. Most often the battery voltage is stabilized close to this value at the last stage of the charging cycle and the internal charging progam decide that the charging cycle is finished when the battery current gets under a predifined value.
I have given some examples of charging cycles of different smartphones in my blog : http://78michel.unblog.fr (sorry most examples are in french).

So I should stop charging when its 99%?
How many hours does ur tab lasts after charging 99% ?? Cuz mine doesnt lasts even 4 hours .. never charged 99% (just bought it somedays ago) did it yest , its working well now .
Screen takes too much battery ,.. ny way arround it to have better batery life? i saw CM10.1 but it has probs with gsm device so I m not using it ..

I think it is better for the battery life to stop charging if the state of charge level stay on 99%, because the charging current is maintained continuously in the battery and I think this is not so good for the battery life.
You can check the battery current in the battery with diffrents battery monitoring systems. I use Battery Monitor Widget. This is very convenient app. to analyse the charging cycle and the draining of the battery.
Analysis of my 5110 here: http://78michel.unblog.fr/samsung-galaxy-tab-2-10-1-tests/
The screen of these tablets is the most current draining component. At max screen brigthness the battery life is a less than 6 hours on my 5110. The brightness should be setted as low as possible to improve battery life, other componenet such as WiFi... GPS have very low impact on the battery life.....
I've been using my Hyperion 7000mah battery without any issues for the last 6 months. The other day, I decided to run the battery down. I ran it to 17% and then recharged it. The next morning, when I woke up, the battery was only 40% charged. I left the phone on the charger the entire day and it only got up to 85%. For some reason, the battery just won't take or hold a charge now. I'v tried turning on and off fast charge, I've tried wiping battery stats, I've also tried several roms and kernels, but nothing seems to affect the battery charging rate. Does anyone know what could've caused this to happen and more importantly, how to fix it? I'm really frustrated that I'm back on the stock battery and that I have a $30 paper weight.
I mistakenly posted this in the wrong forum at first, so here it goes again:
I bought this Galaxy Tab 2 10.1 (GT-5110) about a year ago, it runs the original firmware with the recent Samsung update to 4.2.2.
Lately the battery life has become very short. This was not a gradual change, but something that seemingly happened over night. I charge the device with a travel adapter that claims to output up to 1 A. The battery monitor shows that charging works as expected and the device charges to 100 % .
In use the battery shows 100 % for a while, but after about 20 to 30 mins jumps to 4 % , giving me the low batter warning. I am travelling and the only change I can think of is, that mains power here in Canada is 110 V instead of the 220 V back home in Europe, not that I expect that to be a problem.
I don't notice the device getting warmer than usual, so I don't believe, that the battery really charges to 100 %. Is there anything on the software side I can do to investigate this further?
Thanks for any advice!
EDIT: I just noticed, it's actually not the battery, that is dying. It is a error in the measurement. The battery life is normal, however the charge measurement shows nonsensical behavior: It goes to below 10 % in less than half an hour and then goes back to full, repeating this in cycles, like a sawtooth wave. So I suspect either a hardware fault in the measurement circuit or a software problem.
Here's a screenshot of what the battery info looks like, mind you the device has not been on the charger the entire time:

i think the problem is with the charger
drain the battery of your tab completely and then charge it fully upto 100 % with stock original charger and see if you notice any difference

What makes you say that? I've been using that charger instead of the Samsung charger at home for a long while now.
For me it may be the hardware issue, because software doesn't consume battery in the background so rapidly.
#If you are not sure try this options
For Hardware issues:
*Make sure your charger is working properly (Completely drain your battery and then connect your charger and charge for few half n hour and then reboot your phone and check your battery status and use your tab normally for few minutes and keep an eye on the battery consumptions)
If your battery is gradually decreasing no fault to your charger.
If your charger doesn't charge then its the time to either change or repair your charger.
For Software issues:
"GO TO BATTERY SECTION IN SETTINGS AND CHECK WHICH APPLICATION REDUCES YOUR BATTERY OVERNIGHT RUNNING ITS SERVICES IN THE BACKGROUNG AND JUST DELETE IT"
*After using your tab normally go to SETTINGS>APLLICATION MANAGER> and then RUNNING SERVICES.
If you find unnecessary services running in background NY an app which is not required just uninstall those app.
*Try to check your Sync, WiFi, GPS etc. settings to ensure that any app is consuming continuous services and draining your battery.
*Remove recently installed app which are not necessary.
Hope they help.
Thanks so far, I just updated my original post to describe the problem more precisely.
a solution

I had this exact problem, down to the sawtooth battery status profile, tablet model and android version, and fixed it with the following procedure:
After a normal boot, press and hold the power button continuously.
The tablet will shutdown and reboot repeatedly.
Hold the button down for at least 4 complete shutdown/restart cycles, never releasing the button.
After that treatment the battery status shows a nice, normal discharge curve, starting from whatever random place the sawtooth pattern left you at. Run the tablet until it powers down by itself, and then recharge it.
The ugly sawtooth battery status first appeared on the tablet after running an intensely power-hungry application (the battery got hot after 20 or so minutes of running). After that, the discharge rate seemed to have a flipped sign, where if normal discharge rate per minute was positive, the altered, aberrant discharge rate was negative. CoPilot was the offending software; however, that may be a post hoc ergo propter hoc logic error on my part.
The messed-up discharge rate would prematurely terminate charging if the table was on, so the only way to get a full charge was to turn the tablet off and attach the charger.
Hey guys I am a long time Android enthusiast. I have one of the most popular Samsung devices which is the Samsung Galaxy fit. The problem with my Samsung Galaxy Fit is the battery. Earlier before any tweaking battery used to be normal. After I installed CM7(official build). My battery started draining randomly. At first it was ignorable but then the problem became severe. From 100% it would drop to 88% in just 2 mins use and then from 88% it wud drop to 70% in another 5 mins and the entire phone would be dead in just 3 hours at best. When I would charge the phone again the battery will also be charged randomly going from 5% to 20% and then 20% to 40% all this in just 10 mins. In no less than 20 mins would my phone be 100% charged but that's fake as the battery would drain from 100% to 0% in three hours.
Following are the solutions are tried
Changed the batter,used a brand new original battery(FAIL - DID NOT WORK)
Flashed stock Rom (FAIL - PROBLEM STILL PERSISTS)
Changed Charger (FAIL)
Recharged battery on a different phone and then inserted the battery in fit (FAIL)
If anyone has any solution please let me know. I AM ALSO WILLING TO DONATE IF PROBLEM GETS SOLVED.

You could try Battery Calibrator.. The app is available on Play Store.

Hope this will help you..
1. after flashing custom ROMS, back to recovery or CWM then wipe the battery stats.
2. calibrate the battery while device is on, i ussually use Mugen Power app (install app, choose the standard battery, charge until 100% then click calibrate, after that use the device until the phone is dead then charge until 100% again while device is off).
other Calibration apps ussually have the same steps like the steps i mentioned above, so just use one app..
3. if you still having the battery drain, maybe you should go check the hardware in some technician, coz it could be the hardware that has the problems.
This is my first time encountering this problem.
I was charging my Note yesterday when it reached 15% of the battery. However, even though it was connected to the charger and the charging icon appears, the battery life of my Note is decreasing until it drains the battery. I charged it overnight but unfortunately, It only charged up to 3%. I already sacrificed my files just to reset/reboot the Note but the battery won't still charge properly.
I've tried almost everything. Wiped the cache partition, rebooting the tablet, and uninstalling everything. But the battery stays at 0%. Is it the motherboard? Hope not.
I highly doubt that it's the connector/charger because the lightning icon appears when I connect it. I'm a newbie. I really want to identify the problem and solve it.
Define problem first to eliminate .
Replace battery or use another charger to rule out battery/charger problems .
Clean usb charging port .
100% charged battery that drops quickly >. factory reset first test again .
