Hi
I wonder if someone can help me.
After the recent firmware update cpuspy was showing that my Transformer would go into Deep Sleep for 90%+. Was obviously happy with that
I got prompted that 12 of my apps had updates so updated them. Thought that would be OK as I was having no problems with them at that point.
However, it never goes into deep sleep now and the lowest it goes is 216MHz. The battery drain when I'm not using it is therefore greater. 2% overnight on standby is now 15%. Not OK
I had taken a back up using App Backup so thought I would use the (only) one I had before the recent updates. The problem is that I have not restored before and have forgotten the password I used. :Muppet: Anyone got any ideas how I can roll back the recent updates and try them one by one to find the culprit. Or any other solutions of course.
Thanks in advance

I had a fully charged Transformer and dock this afternoon and now the dock is dead and the tablet is at 3%. So I saw this thread and downloaded CPUSPY and what do you know, 60% of the time it's at 216mhz, 23% it's running at 1500mhz and deep sleep is only 11%.
Anyone know how to fix this? My dock is a B70 model and pressing keys while putting it on standby doesn't wake it up so I don't think this is a dock battery drain issue is it?
BTW: Running Prime 2.1.1 and roach2010 kernel.
Viffer, does your touchpad wake your tablet? Mine does. The keyboard doesnt but the touchpad does and it may be related to why it won't go into deep sleep.
I have a tf300t with the dock. When I leave it to sleep, it just seems to drain the battery like it isn't sleeping properly. I'm on the latest firmware. I was going to root, but got all new gadget happy and let the newest firmware rollover. Whoops. Anyways I think asus has enough customization baked in that I don't know if any 3rd party rom will support this tablet as well the stock roms. Really the experience is stock/vanilla enough, that I haven't had a problem with the asus firmware. Just missing root (and I know I have a few parachutes left....)
Sorry for the ramble here. Ive read on several forums that people with the tf300t are having awful battery life while it should be hardly using any with the dock attached and sleeping. I have a battery monitor running now to look for drain in the OS, where wakelocks might be happening, but everything points to the dock. I *did* have the dock enabled during sleep option for a long time. I turned it off and still had a pretty persistent drain. Wifi should be disabling during sleep, but without any way of testing I dunno. It seems to sleep (and had even turned off once or twice on its own dunno why) when the keyboard is closed, but something really isn't right here. Anyone know what's going on? I know this is a semi-common problem. I would swap the hardware, but I don't know if that's really the issue.
Anyone experiencing battery drain on ICS? I upgraded, rooted, and removed some of the bloatware to help. Thought it was fixed but my tab is dead again. Says the Android OS is taking up my juice. Was never a problem before. Could leave it on standby for days with HC. Now its dead in a day or less.

I initially saw similar behavior, but once I killed the cached processes once, and since have shut down to charge and started new, I haven't seen that behavior.
Do you have WiFi on? Could it be you have apps that are checking to be updated? I know in the past on my phone my Amazon Appstore has a habit of starting itself up and continually checking for updates for itself and for any apps I got from Amazon.
Tried it both ways...wifi on and off.
Try using CPU spy (free in market) or betterbatterystats (free- search for it here on XDA) to see what is eating up your battery exactly.

I noticed that I had a conflict between "Power Savings" settings and the "Display" settings. Putting them both at 1 minute resulted in an always on screen I had to disable the Power Savings to correct the problem.
I did have something odd happen yesterday that seems to have kept my screen on for 4 hours. When I got home and opened my case the tab was very warm, and shut off. And all but entirely out of power, before that it has used about 10 % in 17 hours of standby with about an hour of use, or so.
I think it is possible that an app that previously didn't keep the screen on is now for some reason keeping it on, and I didn't notice when I closed the leather cover.
No issues today, but I am going to try and see if I can find some release notes to tell me about the new download for ICS for the P6210, perhaps this is addressed?
Just to update I installed the betterbatterystats. I showed a couple of things that were keeping my tab awake. Once I fixed those I thought that would be it but it was still draining. I then installed juice defender and had it turn wifi off every time I turned the screen off. That did it. Was never like this before the update but at least its good to know I fixed it.
i suggest checking better battery stats for AudioOut_1 Partial Wakelock. its been draining my phone fast when i upgraded to ICS.
check it here: http://forum.xda-developers.com/showthread.php?t=1629346
now my battery is working great.. i just left my tab for 10 hrs in the locker when i got the tab its still have 97% battery.
for me i just checked and changed my wifi sleep policy from never to when screen turns off and its fine now. :highfive:
I thought about this very issue; I decided to wait.

Did you download the ICS as opensource? Myself, I am deciding to wait for the OFFICIAL verson to be released.
I had the same problem. i even went back to HC to make sure
the issue is not there (it wasn't) and upgraded to ICS
again (full wipe all the time). No luck something keeps
my device unable to go to deep sleep.
Now i'm back at HC again

The version is OFFICIAL .
It's just available only for some countries.
i had the huge battery drain issue while in stock ICS..
the tablet simply refused point blank to go into deep sleep.. in HC it would but not in ICS.. i would take the tablet fully charged to work and not use it much there.. by the time i was travelling back it would be 60% drained in not using it througout the day...
recently flashed to aorths CM9 build and all my battery woes are gone.. now when i get back from work the battery is at 96%!!
battery drain during usage is the same but the CM9 build has awesome battery conservation stuffs for when you dont use it..
would suggest everyone who has these battery issues to move to CM9.. really helped for me.
My battery usage on CM9..

Early results show Juice Defender is helping a lot with mine too. Thanks for the tip!
Next morning: Just the free version of Juice Defender using the default profile took me from 35% overnight drain yesterday down to 3% overnight drain today. That's not bad. It should be even better tomorrow because I've turned off all location services after seeing that BetterBatteryStats says Google location is the worst single offender at keeping wifi going overnight.

Could you tell me how you "killed cached processes" please?
I am having similar battery drain. I am in the process of completely charging battery after it drained 40% in sleep mode last night, wifi off in sleep mods, notifications off, sync off.
I have already done a reset to factory, tried draining battery, and recharged in off position.
Nothing is helping so far. I have installed better battery stats, and CPU spy this morning, and will have data tomorrow morning.
thanks for any help

I had the same exact problem ever since the stock ICS update. My Tab Plus is all stock, no mods at all. The battery would completely drain after one day, and I have very little on the Tab Plus. Nothing helped at all, so I finally bit and did a factory wipe. The battery drain stopped immediately, so I started changing the settings back to the way I like it.
Then, next day the battery went completely dead again! I back tracked and figured out exactly what it is which makes absolutely NO SENSE - turning off wifi in sleep was what was draining the battery! See my screen captures. Notice on the first screen shot, as soon as the wifi stays on the battery drop bar stayed almost flat.
I observed a similar behavior on my 100% stock AT&T GS3 phone also, turning wifi off during sleep causes more battery drain.
I'm getting "suspend backoff" under kernel wakelocks which is preventing my tab going to deep sleep when unused. Everytime I wakeup in the morning my tab is dead. The only solution I found was to turn off wifi if I'm not using it. Anyway fixing this?

Juice Defender. The free version of the app, using the default profile, should take care of this.

Hi
I have a TF700T, unlocked, TWRP and CROMI 3.0.4.
My battery meter is acting weird. For example I recharged both my tab and the dock this afternoon. I unplugged them around 16:30. I've been using my tab for the last few hours (it's now past midnight), not all the time, but quite often. The meter on the tab is still showing 100%. The one for the dock is showing 94%. This is not the normal behavior of my tab and it's been doing that since I unlocked and installed TWRP and CROMI. Before, it would start to go down almost immediately, and would start recharging only at 70%, like it's supposed to.
Last time it stayed at 100% for a while and then started to drain very quickly, and then stabilized and started to act normally.
I'm trying to understand whatcould be the problem. Last time it got "stuck" like that I went to recovery and TWRP was also showing 100% power left. So it's not CROMI. But it's something... Anybody else with the same problem? Or anyone got a solution, an idea? Because I'm worried this will get worse...
Thanks
You could try clearing the battery stats. I think TWRP has the option to do it, not sure about CWM.
Ok thanks sdbags, I'll look into that...
Is there an ideal moment to do that? After a full recharge?
Usually you do 100% charge, clear stats, reboot let it get back to 100% and unplug but to be honest it probably doesn't really matter.
You'll know fairly soon if you still have the problem.
I just checked mine and it started with tablet battery until down to 89%, then dock battery kick in maintain the tablet battery around 89-90%.
The dock shouldn't recharge the tab unless it reaches 70% or lower. At least it's what it was doing before, and what's documented as normal behavior. Since my tab spends 99% of its time docked, I don't know how it would behave undocked...
Looks like it solved the problem for now. Thanks sbdags!

Well, unfortunately, it isn't solved. When I deleted batterystats.bin it went back to "normal" at first, the tab was fully charged and it started to go down almost immediatly after I unplugged it. But yesterday it died on me while the gauge was still showing a little bit less than 30%!!! I did a full charge last night, and it's back to its old tricks: stucked at 100% for the last 8 hours (overnight).
This is very annoying... Is there anything I can do to recalibrate the battery gauge?
And why is this happening? I didn't have this problem when locked with stock ROM and recovery... I'm not complaining, I just want to understand and maybe try to fix this! Thanks!

Could be a battery hardware issue? Sounds like it's not reporting its current and voltage correctly.
You need to get some battery monitoring apps on it so you can see what is really going on.

Could be, but it's weird that it started just after I decided to unlock. It was fine the first 4 months of its life...
Any battery monitoring app you recommend? There are a few on Google Play... I have Battery Widget Reborn, it does some monitoring, but it doesn't provide a lot of information. I'm sure there is an "ultimate battery app" or something... Any suggestion will be greatly appreciated!

Ok, thanks... Will try that and report!
Ok... So I did some testing... My tab is shutting down (more like crashing) at 28% and showing 6561 mV. I then have to plug it in and wait for 5-8 minutes before it will allow me to boot it.
So I plugged it in... It reached 100% at 8169 mV... But then, it continued to charge. As of now, it is at 8296 and still going up as I'm writing this!!
This issue is the same as issue #2 in this thread:
http://forum.xda-developers.com/showthread.php?t=2090826
Now, I don't know, but it look suspicious to me that this problem started when I installed TWRP and CROMI. Could it be related, somehow??

What happens if you wipe the battery stats again?
The only other thing I can recommended is a total wipe, reflash Asus stock to redo the bootloader, TWRP and reflash CROMI. Others don't have this problem so it is something particularly to your setup.
All those posts you linked are pointing to the 4.2.1 update causing the issue. As we only have 4.1.1 I can't see any relationship unless Asus injected some 4.2.1 code into their latest update which seems unlikely.

I suggest you should do a full wipe and reflash cleanrom and kernel. This way you can eliminated all the possiblility with software and pin it on hardware.

I have the same problem with my battery meter, and just like with you, it started when my TF700T was almost exactly 4 months old. The batteries (dock and tablet) have to be close to drained. I've been using the tablet without batteries for many hours, both yesterday and today. But my tablet battery is showing 100% and the dock battery is at 95%. That has to be wrong.
I have GSam Battery Monitor Pro. It can only tell me about the tablet battery (it's blind to the dock battery). Yesterday when I looked at this, it was telling me that the screen used no power. I'm looking at it now and it says that screen is using 68.6% of the power - that's more like it. But it's weird that yesterday the number was zero. It tells me that the unit has only been unplugged for 5 seconds, and has been telling me that since I unplugged it yesterday. GSam usually saves history, but not in this case because it thinks the unit has only been running on battery power for 5 seconds.
I also have a battery widget that is dual-battery aware. It has a history chart, but it doesn't tell me much. It shows the tablet battery at a constant level of 100% with no dips, and the dock battery very slowly dropping from 100% to 95% over the last two days. This is just wrong.
What's been happening is that the tablet will suddenly shut down when I think it's charged, and then I can't turn it on. I didn't realize what was wrong until I discovered that if I plugged it in for a while, I could turn it on again. Obviously the battery is draining completely, but the meter is incorrect. Also, draining the battery completely then recharging to green (which I hope still means "complete charge") has done nothing to recalibrate the battery.
I'm afraid this is a hardware problem. I guess I need to contact Asus?
I'm also having problems with constant browser crashes - doesn't matter what browser it is, I've tried them all. In general, this tablet has been a huge and expensive disappointment.
Edit: I'm running ICS 4.0.3 stock, rooted but not unlocked. I don't want to upgrade to JB because I need the volume booster app. I've read that the volume problem is just as bad under JB but the volume booster apps don't work (nor do many other programs I use). There is nothing in JB I need. From what I've read, people running JB have all the same browser crash problems, battery meter problems, etc.

I feel your frustration, I have seen more and more people with this issue. Well, we could say that either software or hardware, (not every situation is the same), so usually I recommend to do a factory reset then reflash a full Asus firmware, if the issue stills existed, then we can assume it's hardware issue. At this point, we can give Asus tech support a call.

Thanks for your reply. Have you heard back from anyone who has done a factory reset and reflashed the Asus firmware? Has anyone reported the problem going away after that?
The other thing I'm worried about is that it's a hardware problem that Asus doesn't know how to fix because they don't yet know what's causing it. I can't recall anyone saying they've found a solution to this. I've only seen reports of the problem.
I have other serious problems with this tablet, too. It runs short of memory all the time, though this isn't supposed to happen on Androids. I often have to manually clear memory to view screenshots in the Play Store. And the browser is constantly stalling, freezing, and crashing - every browser. I've tried more than 5 of them. This is especially inconvenient for me, since I make heavy use of the browser on the tablet.
I keep thinking of that pressure-sensitive Samsung tablet I almost bought instead...
Both running stock or CleanROM I have the issue that when I leave the tablet undocked my battery will last days or weeks with the screen off. When I connect the dock and turn off the screen the dock battery will drain to 0% within a couple days and the tablet battery level would be lower than if I had left it undocked.
I've installed better battery stats and deep sleep batter saver and the device is verified in deep sleep 90% of the time.
Any suggestions?
Think that is how it designed to work. Dock will keep trying to top up the tab when it drops below 70% and then when the dock battery runs out it requires extra juice from the tab to keep it alive.

I think my question may have not been clear. One should assume that the addition of a second battery should increase the overall runtime of the device not decrease it. Instead of getting the extra hours of battery life I am getting less battery life with the dock attached.
Same problem
I have the exact same problem. Ive got all the right apps and settings suggested from XDA and still my battery drains when doc is connected.

Ditto, same here.
I'm starting to think this is a common problem, and not just some random one that I was having...
So I installed better battery stats and it is indeed the dock that's draining both it's own battery as well as the infinity's battery. I think I had about 4 hours of asusdec_wake lock coming from the dock when I let it go to sleep, but the strange thing is it only appears to happen after about half an hour of sleep before it kicks in for me (I should point out btw that I'm using a tf201 dock and running cromi-x 4.4 with _that's kernel). After removing the dock from my infinity, I no longer got the battery drain from my tab, but when my tab was docked, the keyboard seemed to drain like crazy along with the infinity, but only after being asleep for about half an hour to an hour. I suppose this is just a 4.2 bug that ASUS might be able to release an update on, or sbdags, as it seems he's done a better job with bug fixes than ASUS has. :laugh:

Is sbdags a custom rom? I'm assuming so. Also your use of the tf200 dock should make no difference. Its been proven besides a firmware change and a slight color change the 2 docs are pretty much the same. I also believe this maybe a 4.2 issue however I have seen this before the latest update with my doc. It does appear to kick in after about 30 mins to an hour for me also. I am trying out a new app that I hope will help called DS battery saver. Ive tried others before to no avail but I figured why not give this one a try. I keep my infinity on the doc all the time so I hope they can fix this issue...

I am trying out a new app that I hope will help called DS battery saver. Ive tried others before to no avail but I figured why not give this one a try. I keep my infinity on the doc all the time so I hope they can fix this issue...

sbdags is the creator of the awesome custom rom, clean rom inheritance xenogenisis, he's also the second poster in this thread. I'm currently running his 4.4 rom and it's incredible! (Thank you @sbdags btw for the amazing rom, you'll get a kind donation once I can get this internship thing figured out :highfive I kind of figured that having a 201 dock wouldn't make a difference, but I just thought I should mention it. As for the draining of the battery, I think we can just assume it's a 4.2.1 bug that can hopefully be patched by ASUS or by one of the awesome developers. I've also tried DS battery saver, and I think it told me the culprit was screen on, but after installing better battery stats, I got a recurring wake lock from the asusdec_lock. Oh well, it's not the worst thing ever right now to just undock the tablet, or remember to shut it off while docked.

I'm not so sure i want to try custom roms yet. I hate not knowing if its the rom or my tablet when trouble arises. I wonder what it could be in his rom that makes this issue go away or does it not? Was not sure if you were saying it cleared the problem up or not.
I have better battery stats & its telling me asusdec_wake was on for 11h 50min. Not sure what that is, assuming it woke the tablet up. Sounds similar to yours though. I do know the google services was what always shows in the battery stat app by asus. I hate to undock as it involves removing my whole case which protects both doc & tablet.

I have better battery stats and so far it has only reported no stats, so not sure what is draining my tablet. I do know the google services was what always shows in the battery stat app by asus. I hate to undock as it involes removing my whole case.

Oop, yeah, sorry, I probably should have made that clear that the problem is still present in Clean Rom Xenogenesis 4.4 and most likely with Stock Asus 4.2.1, so flashing a custom Rom won't do anything to solve it to my knowledge, so I wouldn't worry about that. In order for better battery stats to do it's stuff, you need to set it to "since last boot" and then just restart the tablet. At least, that's what I did to make it work. After that, better battery stats will start collecting data about what's waking up your tablet from sleeps, but it's still kind of hard to pinpoint what app is causing the issue.
What we know for sure is that it's something to do with Android 4.2.1 and being connected to the dock while the tablet sleeping is causing it to drain both the batteries of the dock and the tablet, but this doesn't occur when it's disconnected from the dock, and the tablet sleeps just fine. Also not really sure if this is relevant, but when I had my tab sleeping, it went into deep sleep, but after about half an hour of deep sleep, it had that asusdec_wake lock and then it bumped up to I believe 510 mhz for the rest of it's sleeping time. So, maybe it's a stock kernel thing?
Here's what I think is happening.
Asus don't allow deep sleep whilst the device is charging. When using the dock the device thinks is it is charging so doesn't deep sleep. The devices keeps waking, drawing charge from the dock which eventually runs down.

That could be a reason, I'm just confused as to why ASUS would add this, as I never had this problem in 4.1, but after 4.2 it's happened every time I had my tablet in the dock and let it sleep for long periods of time, and it's not cromi 4.4 as it appears to be the case with stock as well. Also, not only the dock drains, but the tablet drains too, but it's only when docked. When I'm not docked, I go about 1% per hour drain, but when I am docked, I'll go about 10 - 15% drain. Oh Asus, you crazy!
Could this be related to the option to wake-up by pressing a key on the dock, by any chance? I could just be spouting rubbish (which wouldn't be a first), but it seems to me that such a setting would require some kind of wake process.
Do you have it enabled?
I vaguely recall there being a similar issue with a fairly similar-named process a while back. I think it was the wakeup setting back then, but it could also have been Maps and Location Services.

I froze maps and turned off all location access and turned off all wireless functions (location, bluetooth, wireless, etc.) from my tab and it still occurs. It's possible that it could be the asus power saving thing for the dock which is the only real thing I have enabled for the dock, but I'm away from my tab at the moment, so I can't exactly test this theory yet.

Based on my observation mentioned option has no infuence on dock draining problem.
Confirmed Dock Drain
The battery drain is happening to me as well. I couldn't figure out why the stupid thing kept going dead.
Not happy! It's just another problem with this tablet. I wanna like it, but it's one thing after another!
-- ok, venting over --
Anyone find a solution yet? Downgrade the OS?

I believe asus is releasing a new update for our tab in a couple weeks. Over on the tf300 forum, I heard they got a new update that I'm not entirely sure what it fixed, but it may or may not have fixed the battery issue, I'll have to look into that. So I would wait before jumping the gun and downgrading, but that's just me, it's a free country after all.
But as for now, there is no fix that I'm aware of.
