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?
Hey guys,
I'm reading through the dock threads and I see a lot of issues with the battery, but I didn't see anyone with the same problem as me. Maybe it's not a problem, but I figured I'd put it out there just to make sure.
Sometimes my dock will read at 0% battery, then suddenly spike up to the proper battery percentage. It usually happens after it's asleep, then wakes up. Last night I had charged the dock to 100%, then unplugged and plugged into the tablet a short while later. It was reporting 0% and had a flashing orange light. I then charged it today and it held the charge, but still doing the strange 0% to "real" percent thing.
I have both a B60 dock and B60 tablet and I am using Prime 1.7 ROM.
Has anyone heard of this? Is my dock bad? I can still RMA it as it's brand new.
Thanks!
I did a test last night by fully charging the keyboard then plugging it into my tab at 17% battery. When I woke up, the dock had 3% and the tab had 76%. This seems pretty on par with what I'd expect. I just don't want to charge the tab and have it not hold a charge at all.
How do you even know how much your dock is charged?
I use a couple of the dual battery widgets (still haven't decided on one). I sent my dock in for repair on the drainage issue a couple weeks ago. Since getting it back I have noticed that when I wake the tablet up, it can take a long time (Sometimes up to ~5-10 minutes for the dock battery to show the correct voltage). I had upgraded to 3.2 while the dock was out for repair, so don't know if its something with the new dock hardware, or a 3.2 issue.
The other day had the dock reading 0 and even after an hour of use, never did show it had a charge. Thought I was screwed because I had read several threads that said if you ran the dock down to 0, they couldn't ever get it to charge again. Plugged it in overnight and let it set, fired it up the next morning and both were at 95+%.

When you click the notification bar, it says "Docking Connected" and then the dock battery percentage to the right. I'm assuming that is the dock battery percentage... I'm not sure if it's part of the rom, but I think I remember it being there when I was stock.

Thanks for chiming in. I'm thinking this might just be a software issue and not a dock issue then. I'll see how things go over the next few weeks.
I kinda like them always together and then just separate them whenever I want to use the Tablet alone.
Will there be any detrimental effects like the Total battery life will lessen after a long time?
i dont believe so, i run mine that way now, mostly a tablet but every once in a while ill disconnect it and run the batteries to 0 just to get a recharge.

Thanks! I was afraid 'cause I've heard rumors that if you leave phones charging overnight or if you always have laptops plugged in, the battery life would lessen eventually.
with all battery powered electronics i allow them to discharge fully once a month.

There have been reports of some docks with horrible battery drain. Test yours with these instructions I got in a PM a few months ago from someone representing themselves as from Asus (many other XDA members got the same PM). I RMA'ed my dock after testing and it's been great since.
The following is a step-by-step guide on how to verify if your unit can support the new optional battery saving mode:
(1) Make sure your software is updated to 8.2.3.13 or later; and your mobile dock is updated to 0209. ([Setting]>[About Tablet]>[Build Number] & [Mobile Dock version])
(2) Dock the Pad into the keyboard dock.
(3) Go to [Settings] > [Screen] and select [MobileDock Battery saving mode]
(4) Press power button on the Transformer Pad to make the unit go to sleep.
(5) With the option checked, if your unit does NOT wake up with the tap of a keyboard, the new battery saving mode is enabled and working.
(6) With [MobileDock Battery saving mode] checked,iIf your unit still wakes up by a key press, you have the earlier design.
(7) If #6 is true and you also require the new feature, then please contact your local ASUS service center “

I've not really experienced this, so much as in my personal opinion: my phones battery life has lessened considerably since I spent a few weeks of running it down to the at or near the single digits between charges. Can't say for sure though, since what also changed since then, I use it a hell of a lot more too. Now're days I will usually leave it charging if it will be sitting around a while.
My TF, the dock is often depleted or laid low without any real problems; can't say I've done the same to the tablets battery though.

owww.. another question is that would the dock ever lose power while connected to the table?t? ' cause mine still has 3% and it stopped charging the tablet.
In the case of Lithium Ion batteries (which most smart phones and tablets have nowadays, including both TF and dock), it is detrimental to let them discharge to 0% and then fully recharge. It is always best to charge whenever possible, and even leaving your TF plugged in overnight is not bad at all for the life of your battery.

When I first got my TF, I was curious as to whether or not the dock would stop working once it had ran out of battery; testing it, I found the sae result. Dock sticks about 3% and the tablet continues to discharge. I assume the docking connector works both ways and allows powering the dock off the tablet.
I prefer to charge before then though, usually at like 35~19 %. When I undock, I usually leave the dock plugged in to top off, even if it was like 80%.
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.

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 recently diagnosed my TFDOCK with the early battery syndrome. I sent the dock into asus service for my RMA and they returned it with the updated chipset (or so it would seem). I did the battery test again to verify (turn off TF101 while docked, press KB key to turn on) and my TF101 did not turn on as i hoped. This confirms that the RMA was successful and the chipset updated.
Right away i wanted to see if the battery drain issue was resolved. So i charged it up to 100/100, closed the lid (which puts it to sleep) and let it sit overnight. This morning the tablet was at 100, and the dock was at 71. I understand that in standby there must be some drain, but i was expecting something like 0.25% per hour (or something in that range). this was closer to 3% per hour which is quite a bit.
I have read from other threads that this even happens when you turn off the TF101 (full power down). so naturally, now i am concerned that this was not really a battery drain fix at all, just one small part of the fix. I would really rather not have to disconnect the tablet from the dock every time i plan to not use it for a few hours.
So my questions are this then. what are the expected rates of battery drain in different scenarios: standby/off docked/undocked? Does it make a difference if i press the power button for standby vs. just closing the lid? Should i set the wifi disconnect policy to screen off rather than never while plugged in (does docked equate to plugged in)? Is it possible that the prime rom (2.1.1) has some effect on the battery drains. I have the latest dock firmware (EP101-0213) but is it possible that i need to reflash the tablet fw or dock fw (somehow) in order for the updated chipset to be recognized and utilized properly?
NOTE: i waded through a number of battery drain threads and didn't see any answers to these questions. there are a lot of posts though so it's easy for me to have missed one that has the right info. If this is the case please link the thread/post. There are a number of posts that have empirical battery drain data, but none that i have read suggest what is expected (or if one can even expect a standard rate of drain).
Thanks.
SOLVED: my issue related to having the 'always stay on while plugged in' option checked in the development section (and also possibly the wifi disconnect policy to never while plugged in). I have turned both of these off and also installed the auto airplane mode app. Now my batteries barely discharge at all when shut off (and in deep sleep mode). The theory is that the TF101 thinks it's plugged in when you are connected to the TFDOCK, even though there is no actual wall power source. This resulted in the TF101 never going into deep sleep and therefore draining the battery the whole time you think it's doing nothing. I'm not sure how to mark this thread solved, so mods go ahead.
+1 to your questions
My dock does the same thing but even with turning off the tablet while docked over night the dock looses battery.
I'm running revolver.
FYI: I don't have the dock battery drain fault.

Yeah, I was curious about this as well. My dock doesn't lose that much, but it does seem like it's losing a good bit. Mine tends to drop about 15% every 12 hours. I haven't tried turning the pad off and see what the results are. I do have auto airplane mode setup, and the setting to turn off auto wake.

I'm having drain problems with my dock. If I turn off with the keyboard attached and then press a key, the transformer wakes up. So does this mine has the problem and needs the update?
1)Who do I contact to get the mod done , I'm in the UK
2) Can I just send the dock?
3) How long does it take
thanks

I did the same test a while back, and I cannot recall what ROM I was using, but after the overnight test, my dock was at 95 percent. Maybe your CPU doesn't deep sleep? Try getting CPUSPY off of the market and see what happens..
@wilx I sent mine in to a canadian asus service shop and they had it back to me in about a week. I just sent the dock, they didn't want the tablet. Not sure who you need to contact, but start by calling your most reasonable asus tech support and they will probably set up an RMA over the phone. I did it all via email, but started here: support.asus.com
Thanks for the CPUSPY idea, i grabbed it and did a quick 5 minute test. it's now evident that my transformer was NEVER going into deep sleep mode. I believe the culprit is that i have the 'always stay on while plugged in' option checked in the development section. My theory is that the transformer is near oblivious of the dock and assumes that because the dock can provide power that the TF is plugged in! as soon as i disabled this option i could start going into deep sleep mode. I also moved the wifi disconnect policy to screen off (for the same reasons). I will do a quick charge tonight and then again let it sit turned off all night to see the difference this makes. I suspect that this will fix the issues i have been having.
UPDATE: starting at 100 and 98, after 9 hours, the batteries were at 97 and 89. So i lost a collective 12%. A little more than i was hoping but still very reasonable. 72% of the 9 hours was in deep sleep mode. roughly 2 collective hours were it woke up (for whatever reason, unclear on why). I had left the TF and dock open but turned off for this test. the next test i will do with the tf closed on the dock (folded) to see if it makes a difference.
For what it's worth, my TF101 has been off the charger for about 48 hours and received about 4 hours of very heavy use during that time. The dock is at 38% and the device is still at 100%.
It's a B40 with a B60 dock (I think) running Revolver 3.11.1.
OP, it looks like you've just solved your problem. While I don't think that my device charges from the dock battery, it does treat it as though it were plugged in to the wall when connected.
just for reference, this suprised me yesterday. i charged both the dock and the tablet last friday morning both to 100%. i didnt turn the tablet off, just closed the lid. my wifi sleep policy is to turn off after lid is closed/screen timeout after 320 secs( using revolver 3.11).
i came back home last night, turned on the tablet. tablet was at 86%, dock was at 99%. thats pretty good going after 3 days of no use.

I used to get this kind of performance with my previous dock so I know it is possible, but now more like the OP..very very poor. I will try some settings (like he never sleep while plugged in possiblity) otherwise I will be on tablet number 2 and dock number 3 soon..
@luna_c666 i did notice that i didn't go into deep sleep mode for very long (like 10% of the time) while it was plugged in. So this leads me to believe that leaving the dock plugged in (with the TF docked) will cause the batteries to be used the whole time it is plugged in even after it is fully charged. This suggests that leaving the TF plugged in and docked for LONG periods of time would be damaging to the batteries.
Hi, thanks for the info!
Here is what i have discovered..I AM going into deep sleep, so that isn't the problem, although I haven't run a good bench test I do NOT have any of the 'never while charging' settings on, yet while trying to use a batteryy health tester app it would not let me do the test because my TF was 'charging'..well, my tab battery is 100, and the dock is 96, the TF should not be 'charging' IMO, I thought it only charged while the tab was <95%? Yet it wouldn't let me run the test because it said I was 'charging' while the dock ws being used.
I also tried to find the 0209 firmware, unsuccessfully, so if nyone has a link to that I would love to bench test the dock with this firmware, however I am on 0213, and I tried with revolver parts to 'roll back to old driver' to fix battery drain in the options, and it did not change the firmware number so I am not sure if it DID or DIDN'T?
Hmm..think my problem is solved?

I thought patsissons found the fix for my issue that is similar to such battery draining description. But the problem is that I don't have the stay awake while charging enabled and I have the power savings enabled. When my tablet is completely off and connected to the dock/keyboard, the dock's battery gets drained like crazy just equivalent of luna_c666 is describing. So every time I'm done using the tablet and dock, I would have to disconnect the tablet and the dock to prevent the dock's battery from discharging while not in use. And I'm not referring to deep sleep mode. Deep sleep mode still has the same issue, even after the infamous dock RMA fix.
Have you tried using "Better Battery Stats" from the store. It's confusing at first but it can help you learn what app is creating a lot of wakelock requests.
There is a high chance you have a misbehaving app that is waking the device up and doing things. When this occurs, the battery will be drained from the dock since the tablet is designed via hw to always get a full charge when the dock is present.
Ive looked all over and cant find a reason so Im asking here. Ive done a few tests and noticed that over about 8 hours of non use and when the dock has a charge, i only lose about 2-4% of the battery. However when my dock is at 3%, my tablet depleats about 8% over those 8 hours when docked. My dock doesnt have the issues other people had before with it not allowing deep sleep and waking up the tablet. Also, if my tablet is undocked then its the normal 2-4%. It just seems that after my dock is almost fully depleated, it uses more of the tablet batter. Is that normal and is anyone else noticing this? Thanks.

It is normal that the tablet will use more battery to sustain the keyboard as well as itself.

I second this advice - I had a problem a few months ago with my TF101 draining the battery unusually fast, like about 50% overnight.
With the aid of Better Battery Stats I was able to track the problem down to the avast!Mobile app I have installed. A recent update appeared to have defaulted a CPU Wakelock option to ON rather than OFF, which had the result of keeping the CPU running, even when the tablet was supposedly asleep.

I've since also started using GSAM Battery Monitor
https://play.google.com/store/apps/details?id=com.gsamlabs.bbm
It's a lot easier to link the battery usage to the app.
