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...

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!

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.

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.
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.

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 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...
Any tips for improving battery life?
I'm noticing my TF700 loses charge a lot fast than my old TF101.
In particular, the battery drain whilst in sleep is excessive.
I am Stock, unlocked, unrooted and on 4.2
Turn off GPS, disable Maps and Gmail, and turn brightness down as much as you can live with. Also under ASUS customized settings, set it for wifi to shut off always when the tablet is asleep.

^ This.
Also disable 'Location services' (settings),
if you've ever used an ethernet LAN adapter make sure the setting for retain furing sleep is off (This kills both the tab and dock battery in under 6 hours.),
and make sure all games have truly been shut down. (The Tribez kept running for me even when I exited out through the 'are you sure you want to exit' menu. Ate my battery in half a night.)
And if you have any widgets running on the lockscreen, particularly ones that update (like email or the weather) consider getting rid of them.

Wouldn't turning GPS also prevent location service from draining the battery since it is not allowed to get your location? Stupid question really but it should prevent it from accessing Wi-Fi this stopping the zip even though it would be trying.

Logically, it should.
However, for some reason it still keeps trying to triangulate, even in aeroplane mode.(I've tested it.) Doesn't make any sense, but somehow it does it anyway... Probably something Google (or Asus) overlooked.)
I've done all things (I think) mentioned in this thread and still getting huge depletion in battery - mostly in sleep mode.
I can leave my Nexus 7 off for hours and the battery barely moves, but my TF700 guzzles it
Obviously something is still running. I leave mine on standby in my bag all the time, at the moment is been on for a week(literally) and still at 80(tab) and 85%(dock). Try using a battery monitor.
Also, did you truly fully disable Google Maps?

Have you tried installing Better Battery Stats (http://forum.xda-developers.com/showthread.php?t=1179809 )? -- don't forget to open it once, and then let it run for an entire cycle. You might find out what app is causing this.
I've been noticing on the latest stock rom, the standby time for the tablet with the dock is like 2-3 days. However, in cm 10.1, I can go 10-20+days. I open them like I usually do and update them once every few hours to keep them up to date. The settings are the same for the most part. However, for some reason, the stock rom really drains the battery for the tablet when docked. Anyone else notice the same?

Try this, go into wifi settings --> advanced --> set "Keep Wifi-on during sleep" to "never". This way your wifi will turn off while the tablet is sleeping.

Even with this setting, the standby time with dock was always less than without dock for me. If I separate tablet and dock, they would survive for a week (if I didn't use them daily).
For some reason, when connected to the computer without dock, the tablet charges (very slowly). When connected through the dock, the dock battery is empty within a few hours.

And to me happens the same problem, I charge my tablet on Monday and followed every day how much is spent and on Thursday was 85% and on Friday totally empty. It all started to happen after Updates to 4.2.1. Does anyone know what to do

Make sure nothing is draining battery i.e GPS and WiFi so the tablets entering deep sleep. Brightness as low as you can stomach.
If not then try a full reformat with all your stuff backed up.
It has always been 3 days maximum for me. Maybe I use it a lot more often or extensive than you do, but 10-20 days and over sound like paradise to me.

I think he just exaggerated! maybe just 3-4 days with wifi/gps disabled.
The last time I charged mine was uh, let me check...
4d, 5h, 3m, 40s. Has been in my bag without using since then, on standby.. Battery: Tab 87%, Dock 92%. Mine truly does make it about 20 days in total if I don't use it.
You obviously have something running in the background. Maps, GPS, Location services (yes, that drains even with wifi off), a widget...
hey guys i would like to know whats the best battery life wise rom you have use. i leave my tab off fr the whole day and it went down 20%. i read someone went down the same amount in a week.

I wouldn't believe someone actually pulling a month on a single charge (since that is what a 20% decrease in a week implies!). I run about three days on a charge, and that's with the dock attached. (EDIT: I can easily drain the tablet+dock combo in a few hours of heavy (graphical) use.)
You can join in here:
http://forum.xda-developers.com/showthread.php?t=2248896
to see if there's an app going haywire. Most of the actual "bad battery life" cases have a rogue app.
well this person said it wasnt on screen off time. noooooo use
Stand alone tablet without dock? And WiFi on or off? If WiFi is on and it's standalone tablet 20% seems to be fine for a whole day.

With everything off (wifi off, gps off, locationservices off, maps disabled, static wallpaper, no moving widgets, apex launcher, etc) and on standby without ever touching it, mine has dropped 4% in 29 hour.
So it is possible.

Is that avatar you? Damn, you're hot.
Anyway, that way it is in deep sleep pretty much the entire period. I haven't stopped handling my 700 for that amount of time yet. (GPS off, Location Services off, static wallpaper and no widgets is my standard setup as well -- all this drain... ugh!)

I fully agree to this^^ statement. I'm not the OP, therefore.

Yes, that's me Thank you.
Well, it's meivakantie, so I've been home mostly. I've been way too absorbed in Divinity 2 xD Which means I'm on my laptop most of the time (except now, I have to pick up my ID card at the police station. And no, I haven't told them I know their WiFi password is ' Politie.'. :laugh: Do they have to prove their stupidity at every possible opportunity?)
I do have some widgets (Zooper 2x and 1 Eweather HD.) But they're both set to update manually only.

An excellent point; none of us bought a 700 euro tablet to stick it in a bag.

Which version of Android are you running?
Using 4.1, I was getting results similar to yours. Since upgrading to 4.2 though, it seems to be more like the OP's.

Still on 4.1.2. Considering all the mentions of issues with WiFi, Battery and other, I'm a little hesitant to update to 4.2. Also, it looks hideous.

Hmm? Looks the same to me. You mean the new default launcher that ASUS thankfully doesn't ship with by default?
Same as OP
I have the same problem as OP with 4.2 but I have the keyboard dock. I can leave my tf700 for 2-3 days without using it and come back and its dead. This is from a 80-90% charge. I think there must be something with the deep sleep not kicking in.
I am thinking of looking back at the build prop to see if that helps with deep sleep. I have wifi off, gps off, brightness down. I did have location services on but figured I could so that's news to me and the only other thing I have is a moving wallpaper. Could those to really be causing all this drain? There has to be some way of getting deep sleep to truely sleep deep and shut down everything..

New app to help with deep sleep
I just installed DS battery saver pro and I am hoping it will actually help with deep sleep. I had power switch but it did nothing but pop up and bother me and never actually shut anything down. I am hoping this app will actually do what it says it can do and shut down all apps and everything when the screen is off.
I am having the same problem since the 4.2 update. I charge my tablet+dock and after 2 days of standby ONLY - no more juice. Everything turned OFF, never touching the tablet.
Any way to downgrade back to 4.1?

Yes, you can just flash the 4.1 firmware to downgrade. The 4.2 bootloader works fine with the 4.1 rom.
Don't forget to wipe cache and dalvic. If you have problems afterwards you may have to do a factory reset and re-install your apps.
There's a guide somewhere, I believe in the General Discussion section, on downgrading.

Along with the battery drain my battery is showing 100% and never changes.
Anyone else?

Nope - everything fine here. The battery seemed to drain very fast after I flashed the first 4.2 rom. But after a few charge/discharge cycles everything seems to be honky dory.
Took a fully charged tablet/dock off the charger about 16 hours ago. Did the usual surfing, reading the forums, email etc, watched a couple of episodes of Breaking Bad, downloaded the latest Cromi-X rom and installed it with mods - I would call it a day of light use.
The dock s now at 9%, the tablet at 90%. :thumbup:
Your battery calibration may be totally off. Have you tried this:
Let the tablet drain to almost 0%, connect it to your PC via USB cable and make sure the PC is on and not going to hibernate or sleep. Let the tablet trickle charge all night - at least 8 hours.
That seems to have helped in some cases....
