Sorry if this had been discussed before, but I was excited when my battery finally read at 100%. I bought a dock a couple weeks ago and I've been using it for charging since. If I charge it up fully and then pull it off the dock for a few seconds and then put it back on the dock the meter well go up to 100. normally my battery won't read higher than 97. This trick seems to get it up to 100.
Not sure if that indicates that it really is a calibration issue or if just spots charging early. Anyway it was nice to finally see the meter at 100%.

I don't think I have ever seen mine at more than 97-98% - while plugged in.
try charging all the way, unplugging, and then plugging back in.
I do that every day. No joy.
Maybe it its something with the dock. battery lasts forever even if it doesn't say 100%. I'm not too worried about it.
OK... i know that the issue of the dock battery remaining at zero has been discussed before, but i am bringing it up again due to the fact that this was only caused by the latest update a couple days ago. Basically my dock battery will remain at zero and bounce up to 100 and then drop down to zero (all this according to the dual battery widget). The dock light remains a flashing orange as long as it is charging no matter what the widget says. When unplugged, the widget still states that it is charging, and the light switches to the fast orange flash. I'll post a screenshot below of the battery graph so ya'll can see what the battery looks like. Hard reboots (vol down+power) do nothing to fix the issue. Hopefully I dont need an RMA, but chances are this is warranty covered, right? Any ideas on fixes? I am NOT rooted.
EDIT: so now the widget shows that the dock is still at 0 and charging, though the docks light is green. When unplugged, the light is back to a quick orange flash. Dock widget software issue or dock battery hardware issue?
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

More often than not now, my Xoom will not fully charge. It will usually get to 61% and stop there. If the unit is off, the charging LED will start blinking. If the unit is on, the Battery Left widget will start flashing between charging and not charging.
I have gone into recovery and wiped the battery stats and that seems to help for a few days and then it starts doing it again. This unit was bought on day one of the release and sees pretty heavy use. I replaced the charger and that had no effect so I am suspecting it is time for a new battery. Any thoughts?
I have a TF300 with the keyboard dock and it probably spends most of it's time with the keyboard.
Now when I charge the battery it will only charge to 70% and refuses to go any higher (even the lightning bolt on the battery disappears)
The light on top of the tablet stays orange and never turns green.
I've tried to full drain the battery twice now but no luck. I've also been keeping it apart from the keyboard dock to stop it from trying to charge.
I've attached a screenshot of my battery graph to show you. I have rebooted my device several times but this doesn't show on the graph.
