Workaround (works for me)

I don't know if this applies for everybody, but I had the drain issue before as well, but now I don't experience it.

This is what I think is the issue, charging the tablet directly/indirectly with the ac adapter. (either through the dock or directly)

Because ever since my last reboot (off the dock), I have not charged my tablet directly plugged, only via the dock's battery, and I don't see the drain anymore.

Maybe someone can test my workflow and see if it works.

So now the only thing I charge is my dock while it's unplugged to the tablet.

When I see my tablet's battery is low and needs some charging, I plug my tablet to the charged dock, but never directly let the tablet connect directly/indirectly with the ac adapter.

Hope this helps.

and hope asus fix this soon.
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
Thanks for the suggestion. I just tried your approach. Deep sleeping is gone immediately once I dock my tablet :( Need to reboot to regain deep sleeping. So... It does not work for me unfortunately.
[Eee Pad Transformer Q&A, Help & Troubleshooting] jasonchewy:
FYI, mine's a B60.

So just checking, when you plug in your tablet to dock, the dock isn't plugged in to AC right?

Also I dunno how quickly the tablet does to deep sleep after the screen's off (with the profile set to turn off wifi when screen's off), because if I turn the tablet screen off, and on again in a short period of time, the wifi stays connected. So I'd imagine it takes several minutes before the wifi is off, and goes to deep sleep.

But I know this is working for me because CPU spy shows the deep sleep state's time logged is WAY higher than any other states, contrary to when I had the drain, and the 200mhz state was the one with the high time logged.
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
Yes, I did not plug into AC adapter at all. Mine is a B70, the unrootable kind.

I used CPU Spy to monitor the problem. Once the problem got started, CPU Spy showed no more deep sleeping even if tablet was left for several minutes.

My friend called ASUS customer service center. He was told that this issue has been identified and should be fixed in the next release soon. It seems the next update will appear soon, maybe next week.
[Eee Pad Transformer Q&A, Help & Troubleshooting] strong_mind:
found a "solution"

While I was suffering with this bug, I came across a "solution" accidentally and would like to share it with all affected users. By inserting a microSD card into the slot on the tablet itself, this problem went away! This can be easily verified when a dock is connected - the light next to charging connector blinks even when the tablet is supposed to be in sleep. After the insertion, the light stops blinking.

My tablet and dock are B60 version, so I cannot say whether it will work on your hardware if it is a different version.
[Eee Pad Transformer Q&A, Help & Troubleshooting] mlbl:
my guess is the blinking light is indicating that your dock is low in battery. i tried your "solution" but it doesnt work on my b50k dock at all in fact i had the microsd in the tablet all the time before this. i tried re-inserting it, still no deep sleep :(
[Eee Pad Transformer Q&A, Help & Troubleshooting] NHxj4x4:
I've read all 21 pages. My situation after 3.2.1 seems to be somewhat unique. I still have AWFUL battery life, however I can hardly even use this tablet since the update.

1. I'm B70 for tab and dock

2. I cannot charge just the tab 80% of the time cause now my battery icon is a question mark 80% of the time.

3. Sometimes when I plug it into the dock (no power) both batteries will register, sometimes not. Sometimes the dock works, most of the time it doesn't.

4. I cannot reboot the device while it is charging anymore. I get stuck at the 1st splash (tegra at the bottom)

5. I cannot reboot the device any longer while it is docked. Same problem as # 4.

6. My tablet is WICKED SLOW now, choppy, text input is a BEAR.

All of this since 3.2.1 and all Asus can tell me is to factory reset. I am IN LOVE with this tablet, but seriously upset at this. If anyone has any thoughts on the above I'd love to hear them. Tonight I got a full hour of fun with her, everything worked ETC. Then I went to do the reboot after charge, and my battery icon is a question mark again.....FML

[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
I tried as well. It did not work for my B70 :(
[Eee Pad Transformer Q&A, Help & Troubleshooting] Kasush:

Xentheon, is that you?
[Eee Pad Transformer Q&A, Help & Troubleshooting] strong_mind:
Sorry to hear that the trick did not work for B50 and B70. Did you try my trick without the dock connected?
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
No worry. Thanks for the tips. It might help someone. When undocked, my tf has not shown any drain problem so far.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Quacktop:
1. reboot undocked

2. dock

Worked fined here on B50.

But if you have a custom rom chance install Prime 2.0.4 and it's solved.
[Eee Pad Transformer Q&A, Help & Troubleshooting] thomas_pieps:
A B80 here and it is the other way around. When docked no battery loss at all, undocked I have battery loss
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Been sick so it has been sitting on the shelf wifi on, GPS off, undocked. Asus weather widget removed.

No complaints I guess. Still screwed when docked. Awaiting update.

so i got my tablet back today from repairs, and so far so good. installed cpuspy and deep sleep is actually functioning, hopefully this continues after i charge it. so for now i can say .. FIXED
[Eee Pad Transformer Q&A, Help & Troubleshooting] chat2004:
Lucky guy! Maybe they fix something on hardware....;););)
[Eee Pad Transformer Q&A, Help & Troubleshooting] xCal1bur:
well i looked at the repair report, and they done two things, first they replaced a chip in the dock, i'm guessing because of the old dock problems on the B50/B60 models

but the second thing that was listed, replaced IO boards, i'm assuming on both dock and tablet as that is what they had told me would fix it over the phone, and in the notes it said, passed all tests

so atm i'm a happy transformer owner :)
[Eee Pad Transformer Q&A, Help & Troubleshooting] xCal1bur:
epic freaking sadface :(:(:(:(:(:(:(:(:(:(

its on the fritz again, i took it off the dock for a while, and now, no deep sleep, epic cry :'(
[Eee Pad Transformer Q&A, Help & Troubleshooting] fldude99:
There is an update available for the dual battery widget in the market and it specifically states a bug fix for the TF dock. Maybe this app has been the culprit the whole time
[Eee Pad Transformer Q&A, Help & Troubleshooting] leedr:
Unless it is a new update in the last day or so, that does not fix the problem. The bug had to do with not reporting the dock battery after a long sleep an similar. I still have the battery problem after updating dual battery widget.
[Eee Pad Transformer Q&A, Help & Troubleshooting] fldude99:
Me too. That was not the culprit
[Eee Pad Transformer Q&A, Help & Troubleshooting] GJRobert:
Did they just fix the hardware, or did they implement the new firmware in the dock to fix it? :confused:
[Eee Pad Transformer Q&A, Help & Troubleshooting] xCal1bur:
disregard that, they did change an IO board and a chip in the dock, but no new firmware, as of now, the problem still persists after this "fix"
[Eee Pad Transformer Q&A, Help & Troubleshooting] brianl999:
For what it's worth.

I have a B60 tablet and dock (stock). Since the latest update I had been experiencing the battery drain issue. CPUSpy confirmed that, for the most part, it was not going into Deep Sleep. Rebooting would fix it for awhile, but it would always return after a few sleep/resume cycles.

I powered it up around 2:00pm yesterday and received an update notice for the Dual Battery Widget, so I allowed it to update. Version is 0.8.2.

No more battery drain (at least not yet). It hasn't been on the charger at all and the dock is at 85% (tablet is 99%) after over 24 hours, with light use. CPUSpy confirms it is going into Deep Sleep, and I must have checked the thing 20 or 30 times. It's been docked/un-docked several times throughout the process.

So, if you've got the Dual Battery Widget, it's probably worth checking your version. Seems to have been my issue.

Here's to hoping...

Thanks

Brian
[Eee Pad Transformer Q&A, Help & Troubleshooting] leedr:
Check again after charging and I can almost guarantee it won't go into deep sleep anymore until you reboot it. But maybe you got lucky.
[Eee Pad Transformer Q&A, Help & Troubleshooting] lordgodgeneral:
I had this problem for awhile too. I've got a B30 tablet and a B40 dock. Dock had already been sent in for repairs to fix the battery saving mode. On mine it seemed that after the last update, it was wifi, did some searching and started doing airplane mode before putting it to sleep, and that seemed to fix the drainage issue for now. I know Prime was having issues as well because of something screwy with the wifi that Roach had to fix in 2.04
[Eee Pad Transformer Q&A, Help & Troubleshooting] brianl999:
Good point, I haven't charged it yet.

Charging now. I'll update.

Got a sinking feeling you are correct.

Thanks

Brian
[Eee Pad Transformer Q&A, Help & Troubleshooting] GJRobert:
Sad to hear that. Let's wait for the update or use the Prime. :o
[Eee Pad Transformer Q&A, Help & Troubleshooting] brianl999:
It took awhile, but the battery drain is back. I was able to charge it and it behaved for awhile, but after charging the dock alone, it now no longer goes into Deep Sleep.

Back to shutting it down...

Thanks

Brian
[Eee Pad Transformer Q&A, Help & Troubleshooting] leedr:
A reboot right after you take it off the dock will work...for a while. At least on my device. Hoping the firmware update comes soon.
[Eee Pad Transformer Q&A, Help & Troubleshooting] triumph_st:
wow, after installing the dual battery widget update yesterday evening deep sleep is back! Back to 91%. Weird because I am convinced that the latest firmware update is the reason of the battery drain. For the moment my TF is undocked. I do not know what will happen when docked.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Flexer:
Hmm.. As far as I know, my widget (the Dual Battery Widget) shouldn't cause the drain at all..

The update to v0.8.2 stated:

It wasn't a fix for any drain issues. I just changed the widget to show the battery levels even when it's 0%.

Although this same commit fixed an unclosed DB reference, I'm not sure if this could have left the CPU spinning... That's been fixed, so if you've updated to 0.8.2 or higher you shouldn't have anything to worry about

I'll install CPUSpy on my tablet, and see if I've got any issues. Although my tablet lasts for days easily, and I've got the widget running at all times, non stop :)

---------- Post added at 10:08 AM ---------- Previous post was at 10:01 AM ----------

By the way, I've had to send my dock to replace the chip and fix the drain issue. Since this was done I haven't have any drain issues! I have been running Prime 1.9 for some time..

But from time to time I see some random issues with the dock. Like opening the tablet, and touching the touchpad, and it suddenly wakes up (happened just once so far). Or the tablet going to deep sleep mode, and refusing to wake up until I undock and redock. Nothing to serious, and nothing affecting the battery, thankfully

---------- Post added at 10:14 AM ---------- Previous post was at 10:08 AM ----------

UPD: Just installed it...

Deep sleep - 76% of the time (52:55:27)

I don't think my widget had anything to do with the drain :P
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
I had no trouble with the widget undocked. I got over 8 days in standby prior to the update. I think it must have been coincidence.
[Eee Pad Transformer Q&A, Help & Troubleshooting] vikeor:
Here are some screen shots I took yesterday. Everything was ok when I was undocked. Then I docked the tablet to take it to do some work, left it overnight. (wiFi off!) and look... next morning.. dead...
[Eee Pad Transformer Q&A, Help & Troubleshooting] Flexer:
Did you check if your dock has the battery drain bug? Did you have it replaced by Asus?

Before I had mine replaced - I had the same issue. Even when in standby, the dock was eating it's own battery, and the tablet's. After they replaced the chip in the dock - no more issues like this.

Did you try installing the Dual Battery Widget, and checking out how both batteries discharge? The standard android tools in your screen only show the main battery
[Eee Pad Transformer Q&A, Help & Troubleshooting] vikeor:
The dock was disconnected when the drain happened! I only used the tablet docked for about an hour when it was charging it as well (seen on the graph). It was later disconnected when I was using it in bed, left UNDOCKED overnight.

I have Dual Batt Widget, good stuff btw :)
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Not trying to be a **** but if you had read the thread there are many of us that have the same issue. Once docked the drain occurs whether docked or not. Once undocked the only way get it to sleep again for me has been to reboot.

Flexer-Are you still running prime? If so I'm not sure you are in the same boat. Most in this thread had functional docks prior to 3.2.1. The update seems to have broken something.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Flexer:
No, you're kind of right, I haven't read the thread, and I don't know about the issues with the 3.2.1 update.

The only reason I noticed this thread was because of the reference to my widget, questions whether it caused the drain, and misunderstandings about my recent changelog.

So I came to explain my changelog, comment that I've got no issues with it, and if there are any issues it's causing - to find them out and fix them ^_^

Seems like there definitely is an issue with the latest firmware (which makes me not want to update it now :( )

And yeah, I'm running Prime (1.9 if I remember correctly)
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Wishful thinking on their part I think. Like I said I had 8 days on standby (undocked) prior to your update. I noticed an immediate difference after 3.2.1
[Eee Pad Transformer Q&A, Help & Troubleshooting] Bob Smith42:
Hopefully Asus will fix the problem with the next firmware update. I read they are aware of the problem. Not sure I would hold my breath.... ;)

Since I had an old dock, before upgrade to my B6O, I am used to the battery draining overnight. Being frustrated waiting for Asus to fix it (again) I am thinking to sell everything and wait for TF2 or other. Unsure.

I finally got an emulator with ICS running on my Windows Gaming PC, and it works good. So, not having a tablet for a few weeks/months would not slow down my Droid development work.

I really like your new DBW version with the graph aligned per day. With ICS there are lots of changes in battery status, so you might want to start looking at ICS instead of doing updates on 3.2 for TF101? Just an idea.

Have a great weekend. :)
[Eee Pad Transformer Q&A, Help & Troubleshooting] bosert:
Even if I turn off the Wifi, reading pdf or operations like that, I have also noticed a noticeable draining issue compared to when I first bought my Transformer. I had to freeze many applications and services in order to minimize this phenomenon.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Bob Smith42:
I am not using any airplane mode apps, etc. I was experiencing lots of drain after 3.2.1 and it is frustrating. I set the *normal* settings like wifi off with screen. Nothing seemed to work.

Finally, I noticed the screen saver was not working. I set to 15 seconds but it did not come on. I thought it was because I was using a live wallpaper but wrong. What I did was set screen brightness to AUTO and the screen saver is working.

I am still testing to see if battery life standby improves.

Has anyone else noticed setting screen brightness to AUTO helps?
[Eee Pad Transformer Q&A, Help & Troubleshooting] Flexer:
Aww, thanks! I'm glad you like it :)

Hm? Which ones? I haven't seen anything like this in the new sdk highlights!
[Eee Pad Transformer Q&A, Help & Troubleshooting] KevinLuong:
I posted this information in the general forum, but it seems worth repeating in this thread.

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
[Eee Pad Transformer Q&A, Help & Troubleshooting] Kasush:
No offense, but a read of the thread woud have showed that this is all already known. in fact, the issue is the kernel. If you change to a custom kernel such as Prime 2.06 the problem is resolved. People who cannot, or do not wish to, root their Transformers have to wait for an update from Asus. I personally have never experienced this as I run a custom ROM.
[Eee Pad Transformer Q&A, Help & Troubleshooting] justPorter:
thanks

i would just like to say thanks, after reading through this thread i changed a few settings;

- turn off wifi when screen off

- auto brightness

- do not inform of open networks

then i installed auto airplane mode and have had awesome battery life. every once in a while i notice the auto airplane mode gets turned off and i restart it, but i have not restarted transformer and have had no issues.

thanks

[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
Folks, Here is my initial experience with firmware 8.6.5.18-20111028 for TW sku. Observed using CPU Spy (thanks to dev). It's positive so far.

Tablet alone sleeps well.

Docked tablet sleeps well.

Plugged-in docked tablet does not sleep.

When unplugged, docked tablet regains sleep.

Will need to monitor the above over longer time. Keep you updated. Cheers.

Update1: Docked tablet is able to sleep when unplugged after full recharge. No need to reboot.

Update2: At times, keypad could wake docked tablet from sleep. But this does not seem to prevent tablet from sleeping.

Update3: Got sound sleep overnight.

My battery drain is solved.

Dock and tablet both lost 2% today during 12hours of standby with wifi off.
[Eee Pad Transformer Q&A, Help & Troubleshooting] sunsetbay:
David, No you aren't the only one(s). But, I think I have it fixed. My situation was that I after reading all these posts I waited until Saturday to install update from a couple of weeks ago and got the new one(before it briefly got pulled) that fixed the drain problem.

Now I have the new fix, but it's draining like crazy and dead yesterday and this morning.

I did some recommendations in this thread of rebooting the tablet and dock together. The dock is fine and tablet still will not go into deep sleep, so I installed CPU Spy to watch everything. Then restarted the tablet, only this time with the wifi and bluetooth off (about the only thing I hadn't tried)...this worked and has held all afternoon. And I've rechecked at least 10 times, it now goes into deep sleep whether my wifi is on or off now or in the dock or not.

Just to be on the safe side, I'm turning my wifi off and on to save on the battery. Blue Tooth seemed to be using a lot of the battery and I turned this off completely, since I never used it.

Good Luck! Knowing how I thought I was safe with the battery drain problem by waiting for the fix and everyone is saying how it fixed the problem, only I got it anyway - LOL.
