I had the .15 stock update with the Netformer 1.6 kernel and was having fast battery drain undocked. I installed the Android Revolution HD 2.1.1 ROM and battery life has been restored. Very low drain now sleeping well. Of course a few days after I did it, Asus came out with the .18 update, so I don't know if that would have fixed it or not.

Just wanted to let you guys know we aren't the only ones lucky enough to get completely untested software. I just saw an article where 3.2 ota for galaxy killed wifi....on a wifi only device. At least we could still use our tabs.
[Eee Pad Transformer Q&A, Help & Troubleshooting] rob77:
I've noticed a similar battery drain since updating to 3.2.1. In my case its the wifi not shutting down when I put it to sleep. I have the wifi sleep when screen is off checked.Before the update it used to go off 10 minutes after I had turned off the screen (yes I even timed it lol) but now its not doing that and is eating battery whilst just sat there. A test to try is to send yourself an email whlst the screen has been off for a short time
[Eee Pad Transformer Q&A, Help & Troubleshooting] Lanpirate:
Mine is messed up as well since the update. Google services, wifi, and Android os have each been using over 20 percent per day with the tablet in sleep mode. I'lltry a hard reset tomorrow and report back.
[Eee Pad Transformer Q&A, Help & Troubleshooting] surroundedbytrees:
Indeed it looks like the wifi is not shutting down. I opened a ticket with Asus hopefully they come back with an answer

Here's how i checked (hopefully someone can confirm)

I made sure under wifi disconnect policy that it was set to disconnect wifi when screen shuts off

then i opened a command prompt with a continuous ping to the TF it continued to respond to the ping even when the screen was off
[Eee Pad Transformer Q&A, Help & Troubleshooting] strangerthanman:
For me it seems to be the android os that drains the battery.
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
In another thread (cannot locate now), it was suggested that battery drain is not an issue if tablet is undocked. Just need to reboot once after detaching from dock. Am trying that now, looking positive... So we could ditch the dock till ASUS fixes it. Share your findings if you try.
[Eee Pad Transformer Q&A, Help & Troubleshooting] GJRobert:
I have been haunted by this issue for a week too. At least 2% or 3% drain per hour without using nor Wi-Fi radio.

But today suddenly after 8 hours of being idle, my Pad only dropped 2% of battery life (100% -> 98%). Let me recall how this happened:

Put it on the dock and had it fully charged.

Hoping to fix the battery drain, I rebooted the device (connected to the dock).

Detached it from the dock because my driving coach was calling me.

Only connected it to my laptop once during these 8 hours.

So, I'm not sure what factor was really helping. Was it "reboot while docked" or "reboot once while detached"? Or did "connecting to a PC/laptop once" also help? Maybe we can test further.

And I do not think it's the Wi-Fi either. In Battery Status screen, it's usually "Android OS" that drains most of the juice. But I'm not sure. How do you think guys?
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
@GJRobert

From my experiments so far, it seems to me that a reboot, docked or undocked, will return TF to normal battery drain. If I leave the tablet docked, it would behave for a while (as observed by cpuspy in terms of deep-sleeping duration). It would eventually misbehave (not getting into deep sleep), resulting in excessive battery drain.

So, a reboot while docked or undocked seems to always reset the mischief. The issue is that the good behavior lasts only for a while if TF remains docked. :mad:
[Eee Pad Transformer Q&A, Help & Troubleshooting] nupi:
So I am not risking bad battery drain if I don't have a dock to use?
[Eee Pad Transformer Q&A, Help & Troubleshooting] cottinghamm:
Mine drained from 50% charged to 0% & turned off overnight with no activity after the upgrade, it has never done that in the months that I've had it, I agree, there is something wrong with the 3.2.1 update causing this.

That is as well as the forcing the browser to go to mobile sites issue.

Asus have done well until now with updates, this one was either rushed out or not properly tested.
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
I have not experimented enough to conclude this. And what works for my TF might not work for yours. I thought a very easy way to confirm bad battery drain is as follow.

1. Reboot undocked TF - starting from clean slate. Leave WiFi on with policy that disconnects on screen off.

2. Install CPU Spy from Android Market.

3. Launch CPU Spy and Reset Timers.

4. Leave TF idle (screen off) for a duration, say 5 minutes.

5. Unlock TF (screen on).

6. Launch CPU Spy and check that most of 5 minutes were spent in Deep Sleep. Otherwise your TF should be having bad battery drain.

7. Leave TF idle for a longer duration, say 1~2 hours.

8. Unlock TF (screen on).

9. Launch CPU Spy and check that most of 1~2 hours were spent in Deep Sleep. Otherwise your TF should be having bad battery drain.

Of course, you would want to continue to observe CPU Spy over a few days.

Edit: The above steps are for diagnosing undocked tablet. You could use the same steps for docked tablet too (just keep tablet docked all the time).
[Eee Pad Transformer Q&A, Help & Troubleshooting] 2manytoys:
Yep, my battery is draining way faster now too. I'll reboot and see what happens. It's a B70 (stock, new SBK) for reference.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dandmcd:
Same battery issue here as well, it drains to almost nothing by days end with the dock. I am also having problems where it goes in a deep sleep when I have it closed, and I have to fiddle with the power button for a few minutes to reboot the device. Never had that happen before until 3.2.1.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Esoth:
Yeah, I think Roach said something about wifi now preventing the tablet from going into deep sleep.

My suspicion is the "improved wifi" that's in the changelog preventing it from "sleeping". As mentioned here and other threads, cpuspy verifies that
[Eee Pad Transformer Q&A, Help & Troubleshooting] BradleyH007:
:confused: I wish it was that simple. I do not have a dock, but I am experiencing the drain issue. I believe that a few other people in this thread are in a similar situation.
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Thank God I saw this thread. I was starting to think there were just a handful of us in the other thread. I noticed the drain immediately after the update but piggybacked onto this thread because mine was dock related. (Start around post 19)

http://xdaforums.com/showthread.php?t=1251789&page=2

Not everyone in this thread specified if it is limited to docking or just bad life on tablet alone. I can't say for sure about the wifi not shutting off because I've always had mine set to never. On 3.2 I got <2% drain per hour in standby with those settings. That remains in 3.2.1 until I dock. Then the tablet never sleeps until a reboot. I have a ticket in and gave them steps to duplicate. Its been over 48 hours with no response so I will call tomorrow.

Fldude--I think it is all dock related. If you reboot (eliminate dock bug) and leave wifi on the tablet should still sleep if left alone. Mine does.
[Eee Pad Transformer Q&A, Help & Troubleshooting] jerrykur:
I noticed that Bluetooth was on since the update. I turned it off this AM and will see how it effected drain.
[Eee Pad Transformer Q&A, Help & Troubleshooting] tekkitan:
Also have battery drain since the update. TF sitting doing nothing for two days will need a charge (did this as a test). Before when I did the same test (leaving it sit, doing pretty much nothing) it would last about a week without a charge.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Bob Smith42:
So? ASUS no longer needs to accept RMA on the older dock for not holding a charge, e.g. since after the 3.2.1 update everyone now has a tablet running down the batteries without extended standby. No more complaints about the TX repair center crushing equipment? No doubt some ASUS engineers are pleased with themselves. :p

Seems we are never safe, is it time to come outside yet?

LOL
[Eee Pad Transformer Q&A, Help & Troubleshooting] tekkitan:
Nope. That just means we have two devices that drain too fast :)
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
Wifi off when it lasted a week?
[Eee Pad Transformer Q&A, Help & Troubleshooting] fldude99:
Yes I believe you're correct. Rebooting off the dock shows it will sleep on cpuspy when screen is off. The moment it is docked, it will not sleep, even when off the dock (without rebooting). So there it is..I have a B60, but prior to the 3.2.1 update it would sleep while docked. Easy way to tell is if it wakes when swiping the touchpad. This is a bit of a pain but not earthshaking unless you're not near an outlet to charge from
[Eee Pad Transformer Q&A, Help & Troubleshooting] Tittah:
My dock is always connected so it seems I don't experience this problem (B80).

Will do some test while undocked...
[Eee Pad Transformer Q&A, Help & Troubleshooting] rxnelson:
I wonder if they broke something on only the older docks with the update? I have a B50 and I think one of the others has a B60. Did you verify the tablet sleeps when docked?

[Eee Pad Transformer Q&A, Help & Troubleshooting] Lanpirate:
Update: after rebooting and a full charge, my drain seems to be gone. I only lost 20% in the last 24 hours, with minimal use. I only used it for 20 minutes within that 24 hours. I have a dock, but rarely use it, and it was not connected during the update.
[Eee Pad Transformer Q&A, Help & Troubleshooting] cottinghamm:
I charged my dock & left it overnight - it went down to 98%. I had about 70% charge on the TF when I got home last night, this morning it was turned off & when I got it back on showed 0% battery (for the 2nd time this week). I can't cope with this, the TF is draining so quickly when doing nothing it effectively needs to be on charge overnight to prevent it dying.

Asus need to fix this or roll back the update, there was nothing wrong before & I have had no benefit from this update.

If you include the screw up on the browser which now defaults to mobile versions of websites (annoying) this is a poor update.

Anyone know any Asus contacts who can help ?

i am getting the same isue, infact i thought i had a bad battery before i saw this thread.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Tyvesto:
I have one of the first TF and dock (B40) and it seems that thanks to that update the issue with the battery drain with the dock is (almost) gone!

During the night (1am to 10 am), I had the following resuts with my docked TF :

Dock battery : 39% -> 12%

TF : 100% -> 100%

Note : those results are obtained using Dual battery widget.

I have activated the sleep option for the keyboard (although it seems not to work for me)

I had the wifi enabled with the wifi sleep option when screen is turned off enabled

During the day before, my TF+dock was fully charged and I used it a little bit before 1 am (from 100% -> 39% for the dock)

Edit : actually I'm not so sure that the battery drain issue is gone, 39%->12% in 10 hours while doing nothing is quite a lot...But I have the feeling that the battery drain is less than before the update.
[Eee Pad Transformer Q&A, Help & Troubleshooting] mikelt89:
I hate the dock battery, its drains very fast, on sleep mod and on use, the transformer itself battery is pretty good.

Overall I can tell that from my use with the transformer until today it is very good as a tablet, but pretty bad as a notebook (unless android 4 or windows 8 would change that).
[Eee Pad Transformer Q&A, Help & Troubleshooting] Puzzlegirl:
Well I don't really have any battery problems at all after the update - in fact it's never been better! It's stock B70 and spends 99% of it's time docked. It achieves deep sleep when it should according to CPU Spy, wifi is set to off when sceen off and I tend to put it in airplane mode if I'm not going to use it for a while. It drains maybe 1 - 4% on the dock in 6 - 8 hours of non use. It drains 2 or 3% if it's turned off for the same amount of time, so it usually stays on in airplane mode if I'm not using it.
[Eee Pad Transformer Q&A, Help & Troubleshooting] dcoulombe:
A possible workaround

Maybe this can help someone else :

I installed AtomateIt from the market and created some rules to force the wifi to be shut down when the screen is turned off :

- Disable wifi when screen is off :

Trigger : Device' screen is turned off

Action : Activate Airplane Mode

- Enable wifi when screen is on :

Trigger : Device' screen is turned on

Action : Deactivate Airplane Mode

I think that the pro version could be programmed to only do this while unplugged. For now, I only have the free version.

BTW, I tried to do this by turning off the wifi power, but then I get wifi speed of -1Mbps once the tablet is turned on again... The network works correctly, but I like to see my connection speed, so I used the airplane mode.

I've updated my TF yesterday, then created these rules. My tablet is sleeping about 99% of the time the screen is turned off. Even after only 20 seconds of screen off time, I get 18 seconds of deep sleep !

Thanks.
[Eee Pad Transformer Q&A, Help & Troubleshooting] boonkui:
Wow. I was having this in mind but not finding a free app to experiment with. This might well be a good workaround. Experimenting now...

[Eee Pad Transformer Q&A, Help & Troubleshooting] atb1o1:
I have the same issue as well, it started after the firmware update. Not sure what is triggering it but it would drain even if I haven't used the dock. I believe a rogue system program must be running and wouldn't allow the tablet to go into deep sleep. A reboot would clear it up and the tablet will behave for a while.

I found out that the Dual Battery Widget was the reason for my standby problems. After i deleted the widget from the homescreen i have no problems...
[Eee Pad Transformer Q&A, Help & Troubleshooting] punman:
That's because it updates itself every time the battery level changes. The battery level is changing as it's discharging, therefore the service will run some code at whatever interval a battery percentage ticks down.

It's really a Heisenberg problem. Do you want to know how much battery you have? Sure, but you're going to pay for it in battery drain. Silly computers, doing exactly what you tell them to do ... Think about what a battery widget does, for a minute. :)

Guys try this out. I haven't tried it yet, but today, everytime I knew I wasn't going to use my tablet I put it in airplane mode. The terrible drain has stopped since. I just installed the app so I'm going to be trying it out as well.
[Eee Pad Transformer Q&A, Help & Troubleshooting] demod_oz:
I was using this before the update and was getting amazing battery life. It has dropped considerably after the update. The reboot is helping the tablet get back into deep sleep, but after a while something happens and it won't go into deep sleep, the cpu stays at 200Mhz. A reboot is needed to fix this, for a short while.

I've been trying a few of the things I normally do, then checking cpu spy. But nothing I'm doing seems to make the problem happen. Apart from time.

I totally recommend the auto airplane mode app!
[Eee Pad Transformer Q&A, Help & Troubleshooting] strangerthanman:
I have tried the reboot thing and it does nothing while in the dock, having the tablet free from the dock makes everything peachy but I need the dock.

Auto Airplane Mode is good, I suppose, but same there, it does not make the dock drain any slower. At least not for me.

What I do think would help though is if Asus put in some extra hours and send out a fix for us.
[Eee Pad Transformer Q&A, Help & Troubleshooting] Korumera:
Hmmm

after the update my battery life is also very bad. It drained to 0% without doing nothing and battery widget said that status was dead, but after a few minutes on the charger it said charging again. Dont know what's wrong.
[Eee Pad Transformer Q&A, Help & Troubleshooting] oliverh72:
Same for me...

I just wanted to chime in - I have a B60k dock, rarely take the TF out unless I'm playing a game that forces portrait.

Before the last dock firmware update, I'd get 3 days of on/off use. Some games, always connected to WiFi, downloading apps, using ThinkFree, etc. The third day I'd generally squeak out enough juice to last till the evening. I've only had it a month, but it's been pretty consistent. Always 3 days.

Since the dock firmware update/3.2.1 (not sure which exactly is causing it), I used the TF yesterday all day and closed it last night, like normal. It was at 54% (only single battery widget, so I only know what the "real" battery life is after the dock's battery is dead, which previously took more than a day). This was the same for the last week or so, but I haven't been specific about looking at the remainder.

So something is definitely dodgy. I'm going to try the dual-battery widget, knowing it'll suck a bit of battery itself, but I'll have a more exact idea of how it's draining, as well as the auto-airplane mode app.

Here's hoping. But the thing is... this update clearly fixed things for people with B70 docks and screwed the rest of us. What gives, Asus? If it keeps doing this over the next week, I'm going to phone them and create a ticket and I'd suggest that everyone else with this issue do the same so that we can get this resolved, ASAP.
