I have a weird battery issue. I will charge my tablet with dock or the dock by itself all night. The next morning when I plug the two into each other the dock battery reads 100% but drops to 70% within 5 minutes then discharges normally. This makes me believe it is not really charging fully.
I have seen some battery issues but not quite like this. My tablet is a B70, dock is a B60, using Megatron Rom.

Check out a battery app to make sure your battery is healthy and clear the battery stats in CWM
Ok should I wait until fully charged to wipe battery stats or can I do it any time?

guide to keeping battery healthy (not mine)
1. Charge your phone fully to 100%
2. Reboot to ClockworkMod, go to advanced, "wipe battery stats".
3. Use your phone till it dies (screen goes blank, ignore the battery percentages and low battery warning)
4. Charge your phone again till 100%
5. From now on just try to make sure you charge your phone before it reaches 30%, and you'll be fine with an increased batter performance for few weeks/months.
Thank you.
Perhaps the issue is that I basically use the dock until it dies completely and then some just about every weekday.

ya NEVER let the dock die completely it causes tons of wierd issues
There isn't much I can do. I need it to type all day and that usually means it goes past its charge.

It should go to about 3% then stop it only completely drains if the tablet drains too
If it actually goes to 0 then thats a hardware issue
I am pretty sure I have seen it hit 0 before. I will watch it this time. I know I have used it to the point where the light goes past the fast blinking stage and goes out completely and then the tablet battery starts to drain instead. I have never drained both the dock AND the tablet though.
I was planning to get a TF Infinity when it comes out but if this is how finicky things are going to be I may not want another.

Ya thats defiantly not right... It should only drain to 3 before switching to the tablet battery. HW issue most likley
:facepalm:
Well I will try wiping stats after I charge it tonight and see if that helps.
Thanks for your help.

I've got the dock for 2 days now. After unboxing, I charged for 8 hrs following manual instructions. Used it with the Pad for some hours (I don't remember for how long) till it ran out of battery, charge for another 8 hrs last night. Then I left it undocked for about half day. As I was running out to a cafeteria, I just docked the Pad (which was in standby state), hop in the car, and now, when I open the pad, the dock's battery is completely ran out, 0%. My dock S/N is B80. Has anyone countered the same problem? What is happening with it? Thanks.

I believe that there are apps in the Market that will allow you calibrate your sensors.... Take a look - let me know if you can't find anything...

I've had some issues lately with the newer firmwares where the tablet refuses to go into deep sleep until it's been rebooted, especially if you leave the browser with tabs open for an extended period of time.
Been using CPU Spy to keep track of it. It doesn't really seem to be related to any specific apps (ran it this way for a week after a full wipe and not installing anything new on both stock and Prime 1.8.4) in that even with a nearly blank slate it will still do this. Haven't figured out why yet but a reboot seems to temporarily fix it.

I have tried to find but it seems there is no apps that can deal with dock battery calibration. Could you help to post the link? Thanks.
What's weirder now is that I undock the pad, charge the dock with stock power cable/adapter, after 2.5 hrs, the dock battery is still empty, red light keeps blinking. Is it a sign that my dock is malfunction?

Well, I found some suggestions in the link below, tried "Cold reboot" and the problem seemed solved, at least for now

Sounds like the issue you have is more to do with the dock not charging over any excessive drain.
Have you tried charging it connected to the tablet see if it fares any better? Otherwise if its still not charging you may want to RMA the dock.
your problem is no problem you can solve. when the dock is connected, the tablet is using the dock to charge its own battery. once the docks battery is depleted, the tablet will be at 100% still. you should still be able to use the dock till the tablets battery dies as well, but with a blinking dock light

so if you're battery is depleted in the dock does the battery need to be replaced? Is there really no other option?
My keyboard and mouse still work fine the dock just won't charge. The orange light blinks and the dock leaches power off the tablet.
I have a bit of electronics experience and I've tried every reset you can do to the tablet with the dock connected and tried different chargers.
The problem seems to be in the port, the computer doesn't recognize is as a USB connection, so it's not even getting power from there. I read somewhere there is an internal switch that causes the battery to not charge. I flipped the switch with the tablet inserted, while charging and not charging and a bunch of different ways and that didn't help it still won't charge. Do I just need to replace the whole battery?
Have you tried charging from an outlet, not the computer ?
My tf700 sometimes drops to 97% while using it charged, is this normal?
I haven't had this happen, but I wouldn't say it's abnormal yet. Try letting the tablet die, then fully charge it with it off. Then letting it die again. Hopefully it should get your battery back to normal.

Yes. Trying to keep a Li-ion battery at 100% charge all times is bad for the battery.
Yes that's normal. The charger only charges to 100% when sleeping. Every other time it goes to 97% to spare the battery, plus usage eats about 3% anyway.. (Lithium-Ion batteries live longest when kept between 60 and 90%. Fully draining and charging is actually rather bad for it. The only reason you do it once or twice is to recalibrate the battery-level indication.)
It is very difficult to fully drain a mobile devices battery. Notice if you attempt to power the device on it after it "dies", it will notify you the battery is too low, thus the battery is never "empty".

Ive seen that my TF700T does the same thing.

Ah, there we have it. WiFi drains the power like a vampire. (The folklore kind, not the sparkly ones. ) That's what's causing the drops, with WiFi on the battery lasts about 3-4 hours as opposed to 9. Performance mode spikes the CPU from 1.5ghz to 1.8ghz, and that also drains more power.
There's nothing wrong with your tablet's battery.
I use the dock (keyboard) always so I'm not happy that the tabled drains the keyboard.
When the tablet gets around 85% battery it's going to drain the battery from the keyboard till it is out of battery.
Is it possible to let the tablet drain the dock if it is around 25%
I have this problem since the first day (stock rom) I went to custom rom's in the hope that it was a bug of Asus.
Maybe some can help me to fix this. It is annoying that I have to use power after 1.5 hours of use
Thanks,
The keyboard works with emty battery.
my keyboard battery is dead right now andit still works perfect mate

I have a wireless charging system, but once the battery reaches a full charge it no longer charges and the battery will start to drain. Is there any way to prevent this from occurring?
I don't know exactly what wireless system you are using but haven't heard of this problem before. I am guessing that it is in the system of the wireless charging and would have to contact the manufacturer to see if they included that option because I haven't seen any different wireless charging options for GS3

It is made this way even tho you plug your regular cord it should drain once full as far as I remember....

But when I charge it with the cord it will hold the charge at 100%. I am use the touch stone mod. It ll charge fine just once it hits 100 percent it will start to drain

I have the LG pad (VZW)and the official VZW back. The issue with mine is the every time you place the phone on it, it beeps and throws a message up on the screen. I stream music while on the pad. Once it's fully charged, it will make the beep, if I leave it on it will continue to beep every 1-2 minutes. Gets really annoying. I have to pull it to the side and let the battery drain down a bit and then place it back on. Another annoying thing is that when it does beep, it cuts into my music.

Is it normal for the dock battery to drain when the tablet isn't connected? I can charge the dock fully, use maybe 10-20% of the battery and then undock it and come back the next day or the day after and it has either no charge or minimal charge left. If I do the same with my tablet and power it off the battery on it stays the same. Just curious before I go and start the tedious return process with Asus if this is normal behavior.

No it's not. My dock holds its charge for weeks if unused.
