I have had the tablet and the dock battery's drain all the way while connected and with the tablet turned off. I do have the latest firmware for the tablet and the dock.
Has anyone else had this issue?
The battery dock still has draining issues, even while off. I'm not sure why your tablet drained as well -- perhaps the dock started to charge it and tablet turned on due to it? or maybe the tablet started to charge the dock while it was draining and ended up both being dead.
yeah Im really not sure what happened but I do know when I went to turn on the tablet it started up and only had about 13% battery left when it was fully charged when I turned it off.
Check your wireless disconnect policies, if its set to Never then that might explain why.

Im not sure where to check that.
OFF as in you held the power button until it asked if you wanted to shut off, or SLEEP, as in just tapped the power button (or lock button on the keyboard)?
The Lock key on the keyboard, or just tapping the power button puts the unit in SLEEP, which is not really sleeping, it just turns off the screen and depending on your wireless power policy, WiFi may still be on. Apps still run. Stuff still communicates with the interwebs.
off as in i held the power button and hit shut down.
Mine is doing it as well. Did a complete shutdown yesterday after fully charging both the pad and dock. Just turned it on and the dock is blinking orange. I also had the WiFi disabled. Even when you do a shutdown it seems something is not shutting down.

ASUS never said that they fix the dock battery drain issue while tablet is docked and powered off. Have they?

im not sure. At least i know its not just me.
I hope they push the update where we can see the battery live for the dock soon.
Mine is doing the same thing. Keyboard was charged when I closed the lid and then blinking 6 to 8 hrs later. Wasn't doing this with firmware .12 with the keyboard battery indicator. I really hope they bring back some of the .12 features soon.

My keyboard dock no longer seems to hold much if any charge, I left it charging yesterday until the keyboard dock light stopped flashing and stays on steady (I assume that means its full) and now 4 hours later the keyboard dock light is flashing and no longer charging the tablet.
if i recall, this is a known issue with the dock. When not in use, it will still drain the battery. If plugged into the tablet at the time, im pretty sure the tablet will drain also. I think asus is aware and i thought i saw somewhere that there will be a fix once 3.1 is out, that will put the dock into a very low power state when not in use.
so i guess we will see once 3.1 is out

I believe only Solid Green is full.
Interesting I've only when seen a solid orange light, perhaps that just means charging, will try again tonight.

Same issue. Had a fully charged dock and a partially charged Transformer.
Was very pleased to see the tablet start to charge when I docked it, and not so pleased when I got up in the morning and both were dead.

Just for the record, I have the same issue. Dock battery drains really quickly when turned off and in sleep mode.

Does it help if I leave the tablet and the dock disconnected when turned off?
My build number is HTK75.US_epad-8.6.5.13-20110925, I have both a docking station and a tablet.
When I have the tablet plugged into the Dock, I still have the docking station drain issue. If I leave the screen turned off with the dockingstation plugged in, I get about 1 day of use before the battery is drained (This is with out using the tablet at all).
If I have them seperated and I do not use the tablet, the tablet alone will last for 3-4 days on standby (the screen off).
ASUS is recommending RMA, does anybody here have feedback before I send in my tablet and Dock?
Thanks in advance,
Brandon

Had the same issue. It is not a hardware issue, RMA won't help. I'm running revolution HD and the problem is fixed. I now drain about 2-3% in 8 hours in standby.
i have the same problem running Prime 2.0.4. Been debating calling support, but i'll give revolution a try tomorrow and see what happens.
Hard reset cured it for me.
I guess you already have tried this:
1. Click on <Apps> on the home screen
2. Click on <Settings>
3. Click on <Screen>
4. Make sure that <MobileDock Battery saving mode> is ticked
And after this make sure to turn off the screen with the power button, otherwise it may not go to deep sleep, it is definitely a software bug, which I'm not sure why they don't fix it (I have a B80, tablet+dock)

You need to send in the Dock to get ASUS to change the circuit board. The earlier docks are able to wake-up the tablet by pressing on any buttons on the keyboard. If you can do that with yours, then you need to RMA it for the issue to even be remotely fixed.
I've got battery saving mode enabled and pressing a key on my dock wont wake up the tablet, but when i put it to sleep , both batteries are completely drained within 48 hrs. Separate, they will both last all week.
if you guys are interested, i may point your attention to this thread (pages 22 and 23), where i have posted that i got my transformer back from repairs with successful results
http://forum.xda-developers.com/showthread.php?t=1287799
the revolution rom seems to be working great, but i'd love to be able to use prime and not have the battery drain. i'm wondering if it is a hardware issue, but revolution's clocking settings overcome that by reducing the cpu while its asleep, and prime doesnt do that by default.
I might try prime with some different setcpu profiles to see what happens..
from the points discussed I would say that although it might not be caused by a software issue, at least it should be fixable with software. It's very simple: IF (AND (any keyboard key pressed=TRUE, deep sleep mode=TRUE),IGNORE,...)
I'm having the same problem and it's pretty annoying. I also noticed that after the tablet turns off I have no access to the keyboard until I undock it and then dock it again.

I agree that there was a hardware issue with the Dock, I exchanged my dock for a newer model the first time that they had the sleep mode issue some time ago. Changing the dock fixed the sleep mode issue at that time. They broke the sleep mode again with the last firmware update, so I don't believe the fix is just to replace the dock, because I have the dreaded sleep mode issue AGAIN!
There seems to be a problem with the latest firmware that affects the handover between the AC adapter and the dock batteries. The transformer will not go into deep sleep mode if it has been connected to the charger (as determined by cpuspy) giving ongoing dock battery drain.
If I reboot the device after the charger is disconnected, then deep sleep mode works as intended and battery life is once again awesome. This may be due to an application conflict of some sort, but as yet I am unable to track down the offending app.
Tldr; Reboot after disconnecting from AC to reenable deep sleep mode

Does setting your screen brightness to AUTO make a difference? (vs. manual setting a level).

Doesn't seem to make a difference - my transformer is set on AUTO brightness by default anyway. It definitely seems to be related to the newer firmware - I had no problems with battery drain under the previous firmware so it is fairly unlikely to be a hardware issue.
Well, the other day I did a shed load of app updates and the battery has been draining over 5% an hour in standby mode since. CPU spy shows that it isn't deep sleeping. Looked at Advanced Task Manager and Maps was constantly restarting every time I stopped it. I've now force stopped Maps and the battery problem seems to have gone away. If it works I'll restart Maps and see what happens.
Well I bit the bullet, rooted my transformer and installed Prime. It's been almost 24 hours and the battery level has barely moved. Let's hope that it stays that way.
Well, after further testing, it wasn't Maps that was causing my battery drain problem but Samsung's own app, MyNet. I force stopped it (I've never used it) and everything seems to be okay.

this helped me.
every time my tablet is docked the battery drains like crazy and both units are dead after one full day and night even sitting idle.
i tried undocking the tablet and rebooting the tablet and leaving it idle and that worked and helped maintain battery life in the tablet. only lost 4% over night
but i still wanted to use my dock.
i charged the dock and tablet together and then after i unplugged the AC cord from the dock, i performed a reboot and then started up CPUSPY and closed the tablet clamshell.
woke up this moning and only lost 4% over night.
while im still jealous that my ipad2 will only lose 4% over a 4 day period staying idle, im still happier that i only lost 4% over night from dock and tablet together compared to being dead over day/night idle.
so to recap, if you have tablet docked and charging. remove the charger and then reboot your system and then your battery drain should be gone. if you dont reboot tablet and dock after removing AC power then your system will drain battery all day and never enter deep sleep.
thanks!
I am on Sky ICS and my phone just doesn't go into deep sleep. Downloaded CPU spy and it just sits at 384mhz. Also I am not sure how to fix this nor get the best battery life. Any help would be greatful.
Not sure about your particular issue but out of curiousity.. does being connected to wifi (with or without cell service) at all prevent deep sleep? I've noticed mine will occassionally sit at 384 also, but eventually does deep sleep.
@cruiz83 - I'm pretty sure there are apps available that can pinpoint the reasoning, such as BetterBatteryStats.. atleast that's what I remember reading in a similar thread before.
Perhaps booting without the sim and setting *#2273# to auto would help this?

Known issue when using a non-standard charging setup; e.g. car charger, etc. Using the OEM charger will resolve the problem; also, I've seen it "fix" the issue when connecting to a PC USB port.

could you elaborate on this? how does using a non-standard charger keep the phone from deep-sleep when it's not charging?
I think what happens is that the kernel wave lock vbus_present stays active. This tells the device that the usb connection is active and stays awake. It happened to me today with my third party usb car charger. Once I plugged it into my PC for a bit, it solved the problem. Why this happens I don't exactly remember.
Correct me if I am wrong.

After fully charging your phone, reboot. This seems to fix the deep sleep bug, at least for me. You can use CPU Test and reset timers and test if your phone is going to deep sleep properly with this method. Right now, my phone has 59% deep sleep. Screen on time is 29 mins out of 1 hour, 11 minutes on time.
I have now had this problem twice this week. I have read other posts that sound similar but the issue seems different.
Twice I have shut down my phone at night. With FULL battery. The next morning, I could not turn the phone on. It would vibrate when I hit power button but not come on at all.
Both times I plugged it in and saw that the battery was COMPLETELY drained. I have seen threads where people post about some battery drain overnight, but this was an entire drain, with the phone off.
This is a major issue obviously as both times the next morning I was on the go and had zero battery life.
Any ideas of what this can be? Does it sound like a physical battery issue? Is the phone maybe not actually shutting down and getting caught in some battery draining process?
Help please.
The best way to test the shutdown issue is pulling the battery after it seems to shut down. Try pulling it for a few seconds and replacing it, but leaving the device off. If that produces the same result, try leaving the battery out overnight.
This seems to only be happening if I leave the battery in the phone.
It happened again last night. Complete drain.
Im not sure but I feel like there may have been a buzz as it turned itself off (not sure if its always there need to experiment further). I picked it up and hit buttons to make sure it wasnt just in standby. It wasnt. it was OFF.
Next morning, no battery.
Any ideas? Id love some help as this is becoming a pretty big problem for me.
Have you ruled out a hardware issue already? If not then call the carrier.

This actually happened to me a night before last as well - twas the first night running Smooth Ice 5.1. Are you on that by chance? Not knowledgeable enough to really comment on whether or not that could be it, but it'd be something to eliminate.
I switched to the new leak last night and the battery life has been excellent off charger all day, for what it's worth.
I am on stock everything.
I am still trying to diagnose the problem.
It seems that when I Power Off, occasionally at the end of the power done I will get a Vibrate. When that happens, I think it is draining while switched off.
When the Power Down happens and I dont feel the vibrate, so far I have not experienced the drain.
Does that perhaps give anyone ideas about what might be happening? Some kind of locked in Process or App? Any likely culprits? Any diagnostics that can show, if it does drain, what drained it?
In the past when it drained I plugged it in to charge and checked battery stats, but it showed Display as the largest consumer. Does the About Battery stats reset each time you plug in and start charging?

It always vibrates when you power off, at least mine does.
The battery stats reset after a full charge has been achieved.
I have no idea what would be discharging it while off besides a bad battery.
Put the BetterBatteryStats application on there. The stock Battery Use GUI interface that is built into the firmware will not show you details enough, it will just show what application used the cpu for X amount and caused the battery to go down X amount.
Put BetterBatteryStats on there to find out what is causing the phone to get drained so quickly. Seems like its not going in deep sleep mode and there is some partial wakelock that is keeping the phone from going into deep sleep. That app will tell you what service or application is holding the largest wakelocks and amount of time it does it for. This helps to determine the issue. Without this, you are just speculating on the problem with the built in Battery Use stats/graph in the Status screen.

Something else I noticed...
Over the last few data, sometimes when I power down the phone, it goes through the powering down process usual, but as soon as its done, the phone vibrates and powers right back on...
Anyone experience this or an idea why that would happen?
Just a thought; If I'm charging my phone with a generic charger (500 mA) and shut it off, it will reboot.
If I'm charging with either the factory wall charger or a 12 volt that triggers AC charge it won't.

The reboot happens when I shut down and am not plugged in to a charger at all....
My galaxy S has been doing this too lately (loses all charge when off overnight). It always buzzes on shutdown.
One thing that mine has is a problem with the usb port, it slowly stopped working and now I can't charge it anymore through the port. I'm wondering if there is a physical short there that is causing the battery to drain. Possibly you have something similar going on, or a short elsewhere in the system.
I've noticed that you cannot shut the phone down when charging from certain chargers too, especially in the car. Very annoying.

Hey guys,
Im still having this issue and wanted to hear if there is a known fix or solution?
Honestly, the severity of battery drain you're describing sounds lije more of a hardware issue than anything else. I would contact yoir carrier as mentioned above. Beyond that, trying out a custom ics like sky or embryo might be your best bet if you prefer the tw interface. Im on embryo 5.1 right now and am experiencing better battery health and longevity than ever before with the skyrocket. But the issue does sound like a bad battery.

This happened to me on one of my i777s.
The phone would even not boot up. It will just vibrate. Turns out the battery was bad. Changed the battery. It was still the same.
Then tried another charger, same thing happened.
So then I changed the whole charging port part in the phone.
Voila! Phone worked like a charm.
So if you have warranty change the phone. If not change the charging port. At least in my case.
I came to a conclusion that even the battery went bad because of the bad charging. Might be a coincidence too.

I have 3 S2 phones that I bought as defect and played around with. Two I could fix but I could not resolve the battery issue on the third phone like by buying a brandnew USB charger part (and trying the ones from the other 2 phones. It has nothing to do with the ROM or anything software either. I narrowed it down to be an issue on the actual mainboard. The weird thing is that the battery discharges way faster when the phone is turned off than when it's in use.
I just let my TF300T run out of battery... And now, after charging it for several hours, I can not switch it on... Nothing happens when I press the power button and when I remove the charging cable and put it back, still no response (I would expect to see the battery image on the screen.)
Does anyone know if this is normal or does the TF300T not survive being totally discharged?
Regards,
BTJ
I've seen this issue with the TF101 before. You should be ok. I believe the resolution was to hold down the power button for 10-20 secs and it should turn on. If not, you will have to charge it for several more hours before it will wake up. According to the manual, minimal charge time is 8 hours for a full charge.
