Hi.
My tablet had some charging issues, but after I bought another cable it worked until now.
It says "97% Full" and it does not charge more than 97%!
What is the problem?..
Thanks.

Nevermind. Here is what I have done to make it work:
1. I unplugged the charger and checked it
2. I flashed through TWRP and pressed Settings -> Fix Permissions, then flashed the Insecure Stock Kernel as I am rooted
3. I cold booted the device
4. I uninstalled the suspect apps which I think that they didn't let the tablet charge correctly
5. I downloaded some battery drain apps and drained the tablet to 0% while watching a movie and playing
6. I plugged in the charger again and let it charge for 4 hours (ignore the red battery icon)
7. I turned it on and it was 100% charged.
8. I uninstalled the apps that drains my battery
9. I hope it charges now, lol.

This is a known issue for lots of devices. I have this issue with my TF101 and my MacBook Pro.
From http://guides.macrumors.com/Laptop_Battery_Guidep/:
What is "full cycle"?
A cycle is when the total battery power is less then 50% before it is recharged. The battery electronics monitor the status of the cells during use, and not cycling the battery at least once a week may cause the electronics to get false recordings. It is best to fully drain the battery before you charge it up again. Seeing a fully charged in your battery status monitor as 99% is a good indication to fully cycle your battery.
Thus it's always good to completely drain your battery and charge it fully at least once a month, preferably more. Apple offer a calendar reminder to do it monthly on their website.
It won't charge if it is already charged 95% or more
Drain below 95% then it will charge to 100%

My 727 (AT&T) is rooted stock rom. The battery indicator gets 'stuck' a lot of the time. It happens in both a widget and the default battery indicator in the status line.. They will both show 100% and I know full well that they CAN'T be at 100% after sitting around all afternoon off the charger. I restart the phone and immediately it drops to 42% ...
Anybody else seen an issue like this?
A lot all over. Do a search

what i suggest you do is calibrate the battery.
1 plug it in and charge it to 100%
2 turn off the phone and charge it until it says 100%
3 unplug and turn it on and leave it for 3min.
4 turn it off and plug it in and let it sit until it says 100% again
5 repeat step 3
6 unplug turn on the phone and use it until it hits 0% and turns off
7 plug in the phone and let it charge to 100%
now use as normal and after a few days your battery will read more accuratley and more importantly, will last longer. keep in mind your battery does lie to you but just use the phone and you'll start getting more out of it.
moving forward, charge whenever you can. Lithium ion batteries will last longer if they're charged often (like at 60%-40%).

Yeah, I even downloaded the utility that removes the battery life file, and creates a new one. I guess I need to try one of these procedures again.. I honestly think it is more to do with a bad application, no matter what the battery life meter should not 'hang', and if it does for more than a few minutes, then it should be able to recover by forcing a restart of the app... *sigh*...
This is a common issue with this phone. Look up "battery stuck at 100%" in Google and you'll find quite a few results. Supposedly it's an issue with certain chargers not giving out proper levels so it trips out some indicator chips in the battery and/or phone.

Just reboot your phone and use the stock charger and cable from now on.
I had this issue with the rooted kernel (can't remember which one) but after downloading "battery calibration" from the market and following the in-app instructions the problem was solved.

yeah battery calibration app on market worked for me as well
Seems this is back again with ICS.
Anyone else having problems as well?
I hate to say it, but it seems so, at least based on my first measurements. Back last year, during the earlier round, I took quite a few measurements before and after having the dock updated. When it was over, I saw aggregate battery drain of the tablet and dock in idle as nominally around 0.2-0.3% per hour. A couple of nights ago, with ICS, I measured about 10 times that amount, approximately 2% per hour.
To be fair, I'm in the middle of dealing with the instability and reboot problem on ICS, and I'm hoping resolution of that problem will eliminate the new, apparent battery drain increase. My one night measurement didn't include a spontaneous reboot, but that night it showed about half time deep sleep, and some level of activity the rest of the night.
With me last night my tablet had about 10% battery and the dock had 85% battery.
Leave the tablet docked overnight (with Airplane mode and wifi policy set to never for keeping wifi on during sleep).
Check this morning and the tablet battery is reading 69% and the dock battery is down to 3%.....
I also have the MoblieDock power saving enabled.
Sometimes i leave my tablet with dock at home when i go to school and when I'm back the tablet is powered off and it won't turn on unless i plug in the charger. The battery completely drains out to 0% even though it was charged about 40-50% when left

I'm not sure if you are pleased or concerned about your readings, but they look pretty good to me. I assume that you had been running the tablet separate from the dock earlier, so that it was able to run down to 10%, while the dock still had 85%. That condition should never have occurred if the tablet and dock were being used together.
As I see it, the tablet battery contains approximately 60% of the combined capacity, and the dock about 40%, so I would factor any change in the tablet battery by 0.6 and by 0.4 for the dock. The tab battery went from 10% to 69% overnight (drawing charge from the dock battery), for a net increase of 59%, or +35.4% of total capacity. The dock battery discharged from 85% to 3% for a net decrease of 82%, or -32.8% of overall capacity, so that combining the two (35.4%-32.8%) the overall battery somehow increased its charge by 2.6%, which is highly unlikely, but you are using approximations, so maybe the actual numbers were a few percent off, one way or another, and there most likely was a very small loss in battery power overnight.
Does that jibe with your conclusion, or did you interpret the results differently?

I left my TF & dock overnnight in Airplane mode, and my battery depletion was about 0.2% per hour, back down to the pre-ICS level I had observed before. eboot Logger did show that I experienced a spontaneous, successful reboot in the middle of the night, so apparently having the radios disabled is no guarantee of protection from the reboot problem, but at least the battery loss was acceptable. I went ahead and set the Wi-Fi advanced setting to disable when screen is off, except when on charger, to see it that will keep the idle battery discharge in check.
I consider any of these actions as temporary workarounds, until ASUS fixes the underlying problems. We should not have to be gerrymandering our systems by trial and error to protect ourselves from dead batteries on idle systems.

But I thought the whole idea of leaving the TF-101 on standby with the dock in is that the dock doesn't not draw battery charge to the tablet, its only supposed to do that when you are actually using the tablet (with it docked)? Please correct me if I am wrong.
I've even had my dock completely drain in 2 hours while the tablet is supposedly sleeping. Maybe that was a fluke though, the drain seems to be in line wit Honeycomb most of the time...

My battery has started acting strangely for quite a while now. Essentially what happens is that when I try to charge it, it usually jumps straight from around 50% to 100%. Then, when I unplug it, it will act as if it is discharging normally for around 5%, then it'll jump down to around 45% and discharge normally. And it doesn't happen consistently, once in a while it will charge properly. It happens whether I am using a wall, car, or USB charger. I believe it started when I installed a nightly of CM 7.2 a while back, but it's still happening to me in SBF'd 608, and it could have started when I was still on CM 7.1. I downloaded a battery calibration app, and tried that several times, but it didn't help. Does anyone have any advice?
buy a $5 spare battery charger from amazon or ebay http://www.amazon.com/gp/aw/d/B006EB6LSY/ref=redir_mdp_mobile/175-4779849-7188200

battery is bad, or phone isn't charging correctly

That will fix the symptoms, but I was hoping to figure out how to actually fix it. The battery charges perfectly fine in another D2G, and it charged fine in mine on 608 last night, so it's not the battery. It looks to me like a software issue. I'm going to see if it keeps doing alright on stock, and if it does, I guess I can assume it's a Cyanogen issue. Or an issue with my install of Cyanogen, anyways.
Use another d2g to charge the battery to 100%, then put the battery into your d2g, start up the phone, plug in the charger for about 15 minutes,delete /data/battd and /data/system/batterystats.bin, power off the phone without unplug the charge, after the phone finished power off, unplug the charger.start up the phone and use it normally to it automatically power off,fully charge the battery without start up

I've been having issues too with my droid 2's battery lately, not the same exact issue you are having, but it's like when I plug it to the wall to charge, sometimes (randomly and not often) it won't recognize my battery and won't start charging and a '?' icon will appear on the battery (if the phone is turned off). I've been reading about this and people say that if you 'calibrate' your battery, the problem will be gone, so check in the Google Store for a battery calibration app and follow the steps. Good luck on it !

Hey guys,
You can see the problem in the Screenshot. At one point the phone stops charging fast and goes on charging very slow. It looks like the phone thinks the battery is full and minimizes the charging power. It is a 1500mah battery, bought a few days ago. I also calibrated the battery at 100% in the 4ext recovery. CM 10.2 from 08.08.

Provably not a problem at all. My guess would be that the battery or charging circuits were getting too hot so it dropped the charging current - fairly normal behavior.
The phone is staying completely cool. I think the calibration is wrong. It is supposed to charge slower at 90% Not something like 50

I suspect a cheap battery... What brand is it?
Its a german brand MTec, oder via ebay.
I've noticed my battery does the exact same thing. Charges quickly to around 50% and then very slow for the remaining 50%. I'm using the original HTC battery that came with my Desire S so I just presumed that it was either the due to the battery aging or perhaps due to the CM 10.1 I'm running. Can't say I noticed this charging behaviour before I used CM 10.1 but I didn't immediately notice it after flashing either.
My phone takes around 8 hours to do a full charge. I've noticed that I can get it to charge to 100% more quickly if I let it charge to near 50%, unplug it and leave it for 5/10 mins, then plug it in again. It's starts off with a fast charge again. It slows after a while but overall it's a quicker way to get to 100%. It's probably not the best thing for your battery to do that regularly so I don't do it unless I need it to charge quickly.
Ok guys often we unplug charger when fone says 100% but i found a simple trick. I installed battery saver app
https://play.google.com/store/apps/details?id=com.ijinshan.kbatterydoctor_en
Even after 100% the charging system enters trickle charging system which takes 10 mins even after 100%. Point to note is when the status is at 3 the fone reports the batt is 100% but that is the time trickle charging kicks in..and doing this my battery did showed little more improvement
Please note : I did not use any batt saving options via app i just used it for monitoring the trickle charge...
Really puzzles me why such a basic app would need to many permissions. Better apps on the store that requires much less permissions to run.

No need for any app to do this, I always let my devices to charge at least 10 mins more after reaching 100%.
No need for this application as phone does not give message of fully charged even after reaching 100% and status will be " (100% charging). Once the trickle charging is complete you will get message on lock screen" Fully charged".
80%
There is an option on my Samsung laptop to only charge to 80% to prolong battery lifespan. My Note 3's battery is so good, I would rather see such an app that would stop charging at 80% or 90%.
I usually have 50-60% battery left by the end of a long day. And that's with quite heavy work. I stopped plugging in the charger in the car for my commute, there is no need!

Wow! I agree that the note 3 battery life is the best I've experienced so far but mine is not as good as yours. Will have to try your method of charging to 80%.
When i forget my phone in the charger all night, i get like 20% more battery life out of it!

Just charge it overnight.
On the big screen U do not do anything ... For normal use the battery life is max 2 days. With gaming max 1 day maybe less...
