Hi
My battery for tablet is showing 97% charged as well as FULL word in settings for battery.
Dock is at 100% (showing it on dual battery widget)
How its possible that its full at 97% (tablet)?
Is there way to fix that?
Tnx
It's completely normal. The Transformer will not start charging the device until it goes below 95%. It considers anything above 95% as "full". I believe that it does this so that it's not constantly charging the battery... Just a guess though...

For the past day the battery on the tablet seems to be stuck at 97%. If I plug the charger into it while in standby its says 'charged' but when I unlock it and check the battery percentage it says 97%.
I got the keyboard dock about 2 days ago and when the keyboard and tablet were paired the battery status would just be charging (lightning). Now it's just stuck on the same number. I had some notifications this morning for a firmware upgrade (tablet and keyboard) so I installed those but theirs been no change.
Any idea's ?
If it's any consolation mine's stuck at 96%. I'm guessing it needs to discharge fully and then be charged to calibrate.
yeah..agree this is probably just a calibration issue...it's ok..
Infinite Battery FTW.
Don't know if this is related. But I noticed that until my battery level goes down to 95%, it won't charge back to 100%, when it reads 96% and above even if its plugged in.
Considering how easy it is to boom a Lithium Ion battery I wouldn't be surprised if they decided to be conservative with it. 4% of 16 (potential) hours of use isn't too earth shattering. It does tweak the OCD though!
You would rather have your battery sit at 96% instead of it not being able to take a charge after 8 months..
Hey I was just wondering if its bad for the calibration of the battery to leave the tablet docked in the keyboard all the time?
I dont use the tablet while its charging, i usually always charge it to 100% (while docked), and let the battery drain out completely (while docked) before charging it back up again.
Just don't want to mess up how the battery calibrates or anything (so in the future whenever i use the tablet by itself it won't drain out quickly due to bad calibration)
As long as you charge it to 100% and then disconnect the AC adapter, you won't have problems.
Since the TF has two batteries (one on the tablet and one on the dock), it will manage them both to drain one first and then the other.
The thing that messes up battery life is if you continuosly charge it despite not being drained. Also it isn't wise to let the TF die on battery and then recharge. Recharging the tablet when it asks for it (19-15% of battery remaining) is a good practice.
Cool thanks for the tips, this is my first Tablet (but my fourth android device), and was wondering because i noticed the dock drains out first and then the tab starts draining, but as the tablet is draining, it slowly trickle charges the dock at the same time (so it can still be used).
ex.
TF = 100%
Dock = 100%
then
TF = 98-0%
Dock = 0-3% (once the dock hits 0%, it starts charging off the TF but just enough to use it until the tablet dies)
PS. I created a sugar sync account from your referral so you could get more space lol
Sorry to revive an old thread... but for clarification, should you let both the dock AND the tablet drain before recharging, or is it ok just to recharge as soon as the dock runs out? this way the dock battery doesn't sit at 3% until the tablet battery dies (sometimes a 2-3 days)...
also, how long is too long to leave the tablet/dock plugged in after its been charged? (e.g. if you plug it in before you go to sleep it will be fully charged at least a couple of hours before you unplug it... is this frying the battery?)
thanks and much appreciated!
I dont think that leaving it plugged in is frying the battery, because it stops charging when its full. Also dual battery widget info shows when the battery was charged last time. e.g. last night around 4am plugged in tablet with dock to charge, woke up at 9am, both batteries were 100% (and not hot as while charging) and battery widget showed exact time when it stopped charging, which was around 7am. Rest of the time while plugged in it does nothing i guess

Thanks for sharing your experiences and the logic... That makes sense to me too... However, I do notice sometimes that the charger is quite hot still in the morning.... which makes me wonder. Add to this the whole idea of product life-cycle and planned obsolescence (and things such as internal non-user changeable battery) and I get a bit sceptical... but thats probably just me...
Modern batteries don't like to be drained and last longer if they're 'topped up' on a regular basis. The only time a battery should be drained now-days is if your calibration is off and the software needs to see where the 'top' and 'bottom' of the charge range is.
Also, if your charger continues to charge your battery once it's at 100% you should have that replaced as it's broken.
The old habit of 'deep cycling' your battery is for older style batteries.
If I'm not using my tablet it's on the dock, on a charge. It's fine.
Is there a way to monitor the dock battery?

Yep, get the Dual Battery widget:

try 'dual battery widget' available in market... (if this is what you are talking about...)
Or check out the themes/apps section for the official widget from the prime. There's one themed to look like our tf101. That's what I use.
EDIT: here's the one I'm using

Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?
This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.

Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better
I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?
I have a problem with the battery.
I`m running cw11 m6.
The battery indicator in the status bar sometimes jumps back and forth.
I reset the battery stats via the app "battery calibration".
I have not plugged in the charging cable during this time.
Is the battery broken or a rom bug?

It happens. The graph is an estimation only. It periodically checks the battery Voltage for an accurate reading and adjusts the graph accordingly.
Wiping battery stats won't help anything.
[Info] What are battery stats and is wiping them helpful?

That is a lot more extreme than I've ever seen. Full charge your phone over night and see what happens after.
You don't need any app to calibrate your battery. It self calibrates every time you full charge your phone. By using something like Current Widget you can check when the phone is actually fully charged since it's not when it first reaches 100%.
hey all,
I noticed that from the beginning, my battery doesnt charge to 100% fully. Battery monitor widget says its stuck at 2976mah instead of the 3100mah. Is this bad? i have rebooted the phone and did a whole charge cycle but it doesnt seem to work.
Does this mean my phone is broken?
thanks!
