I'm experiencing battery drain running Cromi-X 4.5 ODEX with _that's kernel, and whenever I pick up my tablet in the morning the battery is drained. I have BetterBatteryStats, but it's to little use when the tablet is drained. So how can I troubleshoot this and find the culprit?
Set alarm clock to 2:00 AM, then look at battery stats. Alternatively, let it idle just for 1 or 2 hours and then look at battery stats.
Alright, I turned off GPS and location services for last night, and I had battery this morning. Turns out asusdec_wake and suspend_backoff was culprits in the kernel wakelock department. Now, for the asusdec_wake I wasn't able to figure out what that was. Some googleing led me to believe it was dock-related, so I turned off the ability to wake the device via the dock lock-button. For the suspend_backoff I found out it seemed to be browser related, namely Chrome in my case. I turned off Tilt Scrolling as was advised under some other forum here on XDA.
Now I'm just crossing my fingers this will resolve my issues. Will have to wait until tomorrow!

I just noticed in the past few minutes that my gmail is pushing to my tablet despite the screen being off and my wifi policy set to off when sleeping. I've also found some issues when it would actually cut the wifi off when sleeping, and when it comes back it doesn't want to reconnect to my router.
My other issue is battery life related. Last night I *believe* I turned airplane mode on before going to sleep and when I woke up 9 hours or so later, the battery was at least 10% down, I think more than that but I didn't take note of it at night. Even if wifi was on, it should've been shut as my sleep policy is that way. Looking through other threads people seem to be experiencing 1% or so battery drain in an hour. The other factor is that I have setcpu installed and a screen off profile that maxes at the second lowest frequency. This morning I installed netarchy's kernel and lowered my setcpu profile so it stays at the minimum frequency when the screen is off.
I'm running Prime 1.3 (didn't do the r2) and have manually removed a handful of the Asus apps that I don't use/want, and I have GPS disabled.
What 'concerns' me is that I have a droid incredible for a while now and with it, I get no battery drain overnight with airplane mode on (at least none that registers) and that's a battery with a fraction the capacity of the transformer. Moreover, I have a very few apps on my tablet whereas my phone has quite a few and basically beyond the stock stuff on the tablet the same apps are on my phone. Also, the battery stats window on the transformer doesn't show any info about apps. I've had my phone on since I woke up, on 3g and I'm at 90% with not much use. And I thought that my phone got meh battery life.
ive had some issues with wifi disconnecting and wouldn't stop disconnecting till a reboot. cant find any news on it. ive tried all firmwares now and still have the issue.
I been having the same issue. Last night I reflashed the 8.2.3.13-20110511 build, to see it it will help. Mine is stock not rooted.
I have the dock and use the pad with most of the time, both are loosing battery life even after I do a complete shutdown. To me it seems it has gotten worse after the 8.2.3.13-20110511 build update. The WiFi is loosing connection when the dock goes dead so I have to reboot the pad to get it to reconnect.
I also have contacted Asus tech. On another thought I really wish in Android you could disable startup apps without rooting.

Was hoping for more replies but my naturally long-winded posts probably scared everyone off...
I wiped my device and installed Modaco's ROM. I didn't touch the stock apps and only things I've installed are Titanium & Tasker. I put together a Tasker profile to kick airplane mode on when the system is put to sleep, and turn it off when unlocked (unless airplane mode was enabled when put to sleep). I also installed Setcpu and setup a profile to keep the CPU frequency to the minimum when screen is off.
I charged to 100% and let it sit overnight. When I woke up I was at 98%, when I got home a little while ago it was at 96%. Note that I hadn't used the tablet other than for a brief minute or two to check the battery stats. As of now I'm showing 15hrs 51mins on battery with a 4% drop. I've had it in airplane mode the whole time. Oppositely, I had my droid incredible at 100% and played Drop7 (great game btw) for at least 20 minutes before going to bed last night, and it was still 100% when I woke up (it was in airplane mode overnight). I find it weird that my droid incredible, with a 1/4 of the battery capacity doesn't drop at all overnight even with a game being played, and the transformer drops 2% in that time idling.
Has anyone wiped battery stats via CWM?
When I setup AutoStart, I noticed the power state event for screen on/off is off by default. I tried turning back on, seems to improve battery on sleep.

Hi
I do nont know but i have strange feeling that after 3.2 update my transformer drains more power. I mean the battery is draining faster than before the patch? Have you noticed similar thing? (i do not have the docking station)
I seem to be seeing that as well, and the wifi signal seems to be weaker. Not sure if I want to put in a problem report.
Wifi signal is weaker for me too, but the battery's been just fine.
I noticed also that the standby battery wasn't as good on 3.2 for me compared to 3.1. After messing around with the device for a while I found that even when the battery saving mode was checked, the keyboard wouldn't wake up the transformer but a touch of the trackpad did. I thought that there might be some background service that was stopping the transformer from going into deep sleep so I used advanced task killer to kill everything and the device would go into deep sleep. Also, I read on another forum that it might be a syncing service for picasa. I turned that off, killed everything using advanced task killer again and battery life now is equivalent to what I got in 3.1.
I feel my batterie last longer. But I have to measure it first.
I've done some (informal) tests, and I'm getting about .5%/hour consumption on standby after 3.2, where I was getting about 2%/hour consumption on 3.1 and earlier. This is just the tablet, mind you.
So, 3.2 has significantly improved the situation for me. I haven't really measured in-use as closely, but it seems pretty much the same (which is about 10%/hour consumption if I'm really using it).

+1 same here
My Wifi is very good
The battery is good
My wifi has improved by a bar and the battery seems a little bit better. But that's only if I don't struggle with trying to get on wifi.
Maybe during use but if anything my standby time is longer.
Battery seems the same to me, as does wifi.

That has been my experience also.
After 3.2 mine seems to be draining the battery quicker with wifi on & surfing. I might get 4 hours of continuous surfing if that.
Me too, last night I have 95% of battery before switch off to the standby mode (screen off with the wifi sleep), but this morning TF has just 72%.
I am now testing it. I switch off the wifi function first, then switch off to the standby mode.
My friend also notices this problem after upgrade to 3.2...he said 52% to 17% just one night sleeping...wow...what a unbelivable report!
Look at the battery use reports on your settings and see what is taking up a good chunk of your battery life besides screen and wi-fi and you may find a problem. For me, I saw that Google Maps took up 25% of my battery and I only used it for five minutes (it said that it was on for over two hours). I tried force closing and nothing worked until I uninstalled the updates for it and haven't turned it on. Now my battery life is much better. You may also want to check applications that are turning your wi-fi on to update themselves, like e-mail and facebook apps, etc.
Check for Google latitude. It appears to keep GPS running even when TF turned off.
I am on 3.2 since yesterday (Belgium) with B6 dock.
Fully loaded and half a day later in standby 63%.
On 3.1 this would have been 83%.
Battery drain is much greater on 3.2 on my TF!
(Damn, I hate the keyboard lagg whilst typing this)
Mine has been better since the update and I have the ****ty B4O dock. I charged mine on Sunday then went on vacation with it Monday, on way home now and only charged it once on Thurs one the dock finally drained and the tab was down to 60%. Seems like they did something to help as that was unseen before, I had to charge it daily.
I also notice faster battery drain after the 3.2 update.
when I went to bed last night: Tablet 97%, Dock 72%.
This morning (about 9 hours): Tablet is the same, Dock 30%. WTH???
I noticed it today. I leave my dock on the Transformer even when its off and folded. I used it a few times to in the span of 2 days tying into a journal. Today the dock was at 3% Screen at 98. Im guessing its feeding power to the screen. The only settings i have different is screen always on. I shut the screen down when im done using it, or set the Transformer aside or off.
Last night before I went to sleep the battery was around 94% after an hour of solid use from a full charge.
I woke up today about 9 hours later and the battery was at 55%. It's been about two hours since then and I'm all the way down to 30% with only about 20-30 minutes of solid use.
What's up with that? Any ideas as to what I can do to fix it?

-Battery calibration, basically drain to 0%, then back to 100% on single charge.
-Try custom rom
-Might be radio, try flashing different found in development thread
-app or widget installed recently?
-look in battery use under settings menu to find what is eating up battery consumption, in your case likely something via cpu consumption (ie not display use)
What is your current set-up?
Check out battery drain threads in general section.
I'm working on battery calibration right now, this is my first day with the phone (I got it about 24hrs ago, actually). I'm gonna let it die then charge it to full.
I'm on a custom ROM right now, QuickWiz v1.0.3. It's blazing fast, no cool features though. I miss my CM7 that I had on my Inspire but the CM7 alpha was a bit too buggy for me.
I'll check into flashing some other radios in a few and I suppose it could be the weather widget I installed. I'll check that and see if it's syncing too often or something.
That's the funniest part. I just looked and I have 1h51m of screen on time (Mostly around 35% brightness, give or take a bit) and it's taking the majority of my battery at 31%. Right under it is Dolphin Browser HD at 13%. I might just swap to another browser, any recommendations? Last under that is the Android OS at 12%, then everything else is under 10% - Cell Standby, Speed Test, Market, then down to 5% which shouldn't matter.
are you using a cpu governor such as system tuner or setCpu? if you are OC'd, id suggest also cpuSpy to determine how long your device is in each state(clock speed)
I am OC'd. i have a setcpu profile for screen off that cuts it down to ~54/400MHz when the screen is off, set to conservative as well.
Hmm, if I had to guess, check the radio. I've had the problem before. As far as browsers go, I like Dolphin HD, just make sure you completely exit out of it when not using, otherwise it can be a resource hog on idle. Since you haven't had the phone long, reflash your rom of choice too if you get such a drive, that has fixed battery issues for me also.
I love my battery life using TPC's ROM with DaG's kernal. I'm also using TPC's CPU zip to govern and set CPU speeds 192-1782MZ without the use of third party programs. Some see zero battery loss when idle over night. I lose maybe 5%.

I installed a new radio with 8% battery left before I went to a birthday dinner. That 8% lasted me through light to moderate use at the dinner for about an hour and a half before, and I got back with 3% remaining.
I also froze a bunch of bloatware which could have also been taxing my battery. I'll wait another few days of use before I flash any other ROM's/Radios to make sure I'm not happy with the battery life and past that, I guess I'll just have to return it for a new battery or an LG Nitro HD instead, if the dev scene starts to pop up for that phone.
Can you link me directly to the CPU script zip?
what was the radio???
I just got the QuickWIz a few days ago and Im having the same battery drain problem while screens off.. its getting on my nerves

Hey guys, I thought I was getting decent battery life until I noticed that if I charge my phone and leave it unplugged overnight, I get severe battery drain.
Last night, for instance, I went to sleep at 12am with 97% battery and woke up at 8:30am with 65%. I had WiFi on overnight because I figured LTE drained more, but my battery use screen is showing that WiFi was cut off shortly after I went to sleep. However I also have noticed other times that I lose 15-20% overnight with data completely off.
I don't think it is a rogue app or anything because I am using the same ~30 apps I have always used and I have never had a problem with any of them. I am coming off a fresh install of CleanROM 2.2, but I have noticed this issue with every build I've used since getting my HOX.
I also noticed that its saying my display is taking up nearly 50% of my battery so far on this cycle, when its only been on for a total of 30 minutes and its been off the entire night.
Are there any apps that will help me figure out what's causing the drain?
Better battery stats check xda it's free and look at partial wakelocks

Want to see bad overnight drainage?
I woke up to a dead phone and this...
Try this:
Charge to 100%
Boot to Recovery
Wipe Data
Delete Battery Stats
Reinstall CleanROM (I'd suggest upgrading to 3.0)
Restart
Run Battery down without shutting off
Recharge
After you recharge, it should be fine. If not, return to stock and try to get it exchanged because it is defective. Just hope the people at AT&T don't check the bootloader, and you should be good.
overnight battery drain and warm.
I've been experiencing the same issue.
Two nights ago I went to sleep with around 73% and woke up with 71% and last night, I went to sleep with full charge, wifi and data off, and woke up to 77%.
Is your device also exceedingly warm?
I've also noticed a few times that it will give an inaccurate charge percentage, until a restart sometimes. So for example, it will read 65% and after a restart, it will read 95%.
I saw a post somewhere about htc smartsync causing some issues. Maybe it could be the cause of this drain? Apparently it shuts off wifi and data between 1 and 7am and only turns them back on to sync at certain intervals. Also it's buggy as hell so it just f's everything up. I'll post the link to the relevant thread once I find it.
Edit: Found it http://forum.xda-developers.com/showthread.php?t=1708492
So the other night I charged my phone to 100%, the LED was green indicating it had come to a full charge. I unplugged the phone and left it on my night stand to see how it held it's charge over night. It was shocked in the morning when I woke up and found my battery had depleted drastically. It had gone from 100% to 47% over night. 53% loss while it was sitting on my night stand and I was sleeping. My old iPhone 4 would only lose about 3 or 4 % over night. This seems ridiculous.
First thing I did was jump into my battery usage screen to see what's been killing my phone over night. This was from roughly 9:30pm till 6am.
I'm running ROM Xi40 126.
It's pretty atrocious with the battery life. I'll have it fully charged, and then unplug it and within about 10 minutes I'm already down to 97%. It's loosing 1% every 5 - 8 minutes and I'm not doing anything with it. Just sitting in my pocket or on my desk.
What could be causing this? I'm going to try a different ROM and see if that helps.
Download betterbatterystats to get a view of what apps may be causing wake locks. What are your sync options? Check Facebook sync, and the actual app settings. Facebook my default refreshes a live feed and every hour, its a real drain. I'm on r123 Xi40 and my battery life has been pretty good.
I've set global sync options to once a day as opposed to hourly or something.
I don't have any widgets open except for a 1x4 clock / weather widget on my home screen.
I flashed CleanROM 4.5 RC1 Lite and it appears to be a lot better so far. Only lost 5% in 30 minutes with screen on and downloading stuff over WiFi and LTE. I'm charging it to 100% right now and will be out for the afternoon, 8'ish hours. I'll see how the battery lasts.
Changing to CleanROM 4.5 seems to have solved the issue. Been unplugged for nearly 3 hours, an hour of which was streaming music from slacker over LTE, and I've only lost 10%.
My guess is there was an application running in the background that got killed with you flashed CR 4.5. Happy you got it resolved though!
Download SmartSync Disabler
So what you wanna do is use SmartSync Disabler. So download it, enable it, reboot. Then you should be good to go. This is a bug where your WiFi and Data connection is turned off and on randomly, and intermittently throughout the night. This causes for the drain and heat issues maybe.
