Hi all
Installed 8.6.5.19 last night. My batteries were 97% TF and 92% dock - did full switch off incl setting airplane mode BUT left tf and dock connected. This am - 12 hrs later - tf is 100% and dock 65%.
I was hoping that this latest firmware might improve the dock battery loss when connected but fully switched off not sleep mode ?
For info - my tf and dock are both very early B40's - I never bothered with the rma/hardware fix - my personal workaround is simply to take tf off the dock when not using!!!!!!
Any advice/comments please?
I have the same model dock as you and you should send it in for RMA. Since i got mine back 3 days ago i Can leave it docked and the battery barely drains while making the TF101 look stylish and complete just sitting there or charging. It really makes a huge difference.
Removing the dock just to conserve power is a small workaround without any real benefits . You still need to carry around the dock if your traveling around outside your WiFi zone or just visiting family. Its one extra step to something that can easily be fixed by sending it in and having the unit behave as it should. All that does is ignore the issue, not a real fix. Its like having a slow ice maker in your refrigerator that you start not to use as much ice in your drinks to avoid the problem of getting a repair man to fix it.Since i got mine back im extremely happy with it and the battery power drain is nonexistent.

If it could've been fixed in the firmware, don't you think Asus would've done so, rather than having docks RMA'd for repair?
The *only* solution is to RMA your dock. I did with mine, and now it works brilliantly.

Yep you need to RMA, ASUS has already stated they cant fix the early docks via software/firmware.
You should definitely get it RMA-ed. With the new firmware, I left my TF docked for 20+ hours sitting in my car the other day. When I came back and turned it on, cpu spy reported 98% deep sleep. Only lost may be 8% or so of battery.
As stated the dock has a hardware flaw and needs RMAing. I have a B40 dock (B30 tablet) and once RMAed the dock works flawlessly.

I was very surprised also. The new firmware actually allowed for deep sleep due to the fact that I can set the damn wifi to turn off when the screen is off and not have to restart.
So, I guess the goal should be to do something so the damn thing will go into deep sleep.
Thanks for the replies everyone - much appreciated. So RMA it is.
A quick further question please. ( aimed at the uk based amongst you) I just looked at asus uk rma page - they ask you to pick a form from a choice of Notebook/pda/eeepc/lcd. I presume the TF is eeepc rather than notebook!!! ( though in the dock it does look like a notebook to me!) More seriously - do I send back the dock alone? or is it TF AND dock - I have seen conflicting advice on other forums.
Thanks again.
Yeah, the Transformer is eeepc and you only send the dock back
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.
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!

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.

No such problems here - yesterday evening 91%+91%, today morning 89%+89%. Stock deodexed 4.2.1 ROM with _that2 kernel and some apps removed.
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.

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...
