I have had the tablet and the dock battery's drain all the way while connected and with the tablet turned off. I do have the latest firmware for the tablet and the dock.
Has anyone else had this issue?
The battery dock still has draining issues, even while off. I'm not sure why your tablet drained as well -- perhaps the dock started to charge it and tablet turned on due to it? or maybe the tablet started to charge the dock while it was draining and ended up both being dead.
yeah Im really not sure what happened but I do know when I went to turn on the tablet it started up and only had about 13% battery left when it was fully charged when I turned it off.
Check your wireless disconnect policies, if its set to Never then that might explain why.

Im not sure where to check that.
OFF as in you held the power button until it asked if you wanted to shut off, or SLEEP, as in just tapped the power button (or lock button on the keyboard)?
The Lock key on the keyboard, or just tapping the power button puts the unit in SLEEP, which is not really sleeping, it just turns off the screen and depending on your wireless power policy, WiFi may still be on. Apps still run. Stuff still communicates with the interwebs.
off as in i held the power button and hit shut down.
Mine is doing it as well. Did a complete shutdown yesterday after fully charging both the pad and dock. Just turned it on and the dock is blinking orange. I also had the WiFi disabled. Even when you do a shutdown it seems something is not shutting down.

ASUS never said that they fix the dock battery drain issue while tablet is docked and powered off. Have they?

im not sure. At least i know its not just me.
I hope they push the update where we can see the battery live for the dock soon.
Mine is doing the same thing. Keyboard was charged when I closed the lid and then blinking 6 to 8 hrs later. Wasn't doing this with firmware .12 with the keyboard battery indicator. I really hope they bring back some of the .12 features soon.

My keyboard dock no longer seems to hold much if any charge, I left it charging yesterday until the keyboard dock light stopped flashing and stays on steady (I assume that means its full) and now 4 hours later the keyboard dock light is flashing and no longer charging the tablet.
if i recall, this is a known issue with the dock. When not in use, it will still drain the battery. If plugged into the tablet at the time, im pretty sure the tablet will drain also. I think asus is aware and i thought i saw somewhere that there will be a fix once 3.1 is out, that will put the dock into a very low power state when not in use.
so i guess we will see once 3.1 is out

I believe only Solid Green is full.
Interesting I've only when seen a solid orange light, perhaps that just means charging, will try again tonight.

Same issue. Had a fully charged dock and a partially charged Transformer.
Was very pleased to see the tablet start to charge when I docked it, and not so pleased when I got up in the morning and both were dead.

Just for the record, I have the same issue. Dock battery drains really quickly when turned off and in sleep mode.

that might be a good idea it might not drain as fast!
Does it help if I leave the tablet and the dock disconnected when turned off?
First, just to clarify the dock battery drain problem is:
With the tablet locked into the dock, and turned off (not standby), the dock battery loses power at a rate of about 2% per hour. This occurs with the tablet off, but locked into the dock. There is a nice long thread about it here.
I went to my local Asus service repair center. I talked to them about the dock battery drain issue. They said they would be willing to look into it, and if my dock has a problem repair/replace.
With that being said, I have not seen a single post of someone saying either 1) they don't have the dock battery drain problem, or 2) they hand the problem successfully repaired by Asus.
If you have do not have the dock battery drain problem, or have had it successfully repaired, Please reply to this post.
I need to know if it is going to be worth the time to let Asus take a look at my dock. I already have a B60 model dock, so I'm not going to get an upgrade to a newer model out of the deal. I don't want to give them my tablet, just to hear back that there was nothing they could do or give me a new keyboard which also has the problem.
So, should I let Asus check to see if I have a dock battery drain problem?
Also, as a heads up, I asked them about replacement USB/charging cables. The service department doesn't have any, and they will call the Shanghai distribution center about ordering some. They said they will call me back Monday and let me know if they can get any. If I can get some extra cables, I will let you know.
Mine seems fine now only about 8% drain during the same amount of hours, Had 0209 update installed but received a minor dock update last Tues, did'nt realise what it was for but after, no drain on dock when connected and closed. All the batch numbers will be the same hardware B3-B6 it will be a software issue, my update popped up as a notification, just installed and bingo.
PS to the above, I leave all radios on GPS WIFI etc, same with my HTC desire HD and Ipad, this will account for the minimal drain. Also I would imagine when docked if the tab loses 1% because of the process of regarging from the dock, it may take more than 1% of dock power to replace it. I mean the collective power of the dock plus the energy need to transfer full power back to the dock might not be equal, if the pad was flat and you had 80% in the dock if you closed it, my guess is you would only get 60% after transfer back to the Tab.
Do you have any information on what that minor dock update is, or where you got it? Also what country do you live in, and which rom do you use?
Strange. Most people with B60 docks are reporting no drain, or at least less drain.
Is your Tf also B60K?

What do the specifications state the drain SHOULD be? As clearly without knowing that, how can anyone know something is outside specification...
Cool, good point about knowing the specifications so I can tell if I am out of spec. However, it's a lithium ion battery. I really hope specifications do not include a drain over 1% a day. If they do I am really really disappointed in Asus. I have plenty of devices that have lithium ion batteries, most of them have battery drain near zero. I have a 5 year old laptop that will drain out the battery in about a week. But that is a very old piece of equipment, not a new computer.
If most people with the B60 are reporting no drain, then that is the answer I need. I have a drain of 2% per hour. If people are reporting less drain, how much drain is the average person experiencing with the B60? Based on the dock battery drain thread, I think it is 2%.
Also, where do you see the posts of people who have no battery drain? I've only seen one post of someone without battery drain, and 1 post of someone with less that 1% per hour.

I'll test my dock tonight.
Just to verify. Im supposed to turn off the tablet completely and keep it docked then record the percentge drop on the tablet after a few hours right?
I got my tF and dock from the first or second batch of shipments I believe. Not sure what version of each I have. how do i go about checking?

Record the percentage of both the dock and the tablet before shutting down.
I get the drain as well, B50 on both the tab and the dock. The drain is NOT normal Li-ion drain as it doesn't happen when they aren't docked.
Additionally - to the people that say it's normal to have this much drain with the radios turned on, we mean that the tab is turned OFF. Not screen off, but the entire thing off - as in hold the power button until the pop-up and push the soft turn off button on the screen.
I kinda like them always together and then just separate them whenever I want to use the Tablet alone.
Will there be any detrimental effects like the Total battery life will lessen after a long time?
i dont believe so, i run mine that way now, mostly a tablet but every once in a while ill disconnect it and run the batteries to 0 just to get a recharge.

Thanks! I was afraid 'cause I've heard rumors that if you leave phones charging overnight or if you always have laptops plugged in, the battery life would lessen eventually.
with all battery powered electronics i allow them to discharge fully once a month.

There have been reports of some docks with horrible battery drain. Test yours with these instructions I got in a PM a few months ago from someone representing themselves as from Asus (many other XDA members got the same PM). I RMA'ed my dock after testing and it's been great since.
The following is a step-by-step guide on how to verify if your unit can support the new optional battery saving mode:
(1) Make sure your software is updated to 8.2.3.13 or later; and your mobile dock is updated to 0209. ([Setting]>[About Tablet]>[Build Number] & [Mobile Dock version])
(2) Dock the Pad into the keyboard dock.
(3) Go to [Settings] > [Screen] and select [MobileDock Battery saving mode]
(4) Press power button on the Transformer Pad to make the unit go to sleep.
(5) With the option checked, if your unit does NOT wake up with the tap of a keyboard, the new battery saving mode is enabled and working.
(6) With [MobileDock Battery saving mode] checked,iIf your unit still wakes up by a key press, you have the earlier design.
(7) If #6 is true and you also require the new feature, then please contact your local ASUS service center “

I've not really experienced this, so much as in my personal opinion: my phones battery life has lessened considerably since I spent a few weeks of running it down to the at or near the single digits between charges. Can't say for sure though, since what also changed since then, I use it a hell of a lot more too. Now're days I will usually leave it charging if it will be sitting around a while.
My TF, the dock is often depleted or laid low without any real problems; can't say I've done the same to the tablets battery though.

owww.. another question is that would the dock ever lose power while connected to the table?t? ' cause mine still has 3% and it stopped charging the tablet.
In the case of Lithium Ion batteries (which most smart phones and tablets have nowadays, including both TF and dock), it is detrimental to let them discharge to 0% and then fully recharge. It is always best to charge whenever possible, and even leaving your TF plugged in overnight is not bad at all for the life of your battery.

When I first got my TF, I was curious as to whether or not the dock would stop working once it had ran out of battery; testing it, I found the sae result. Dock sticks about 3% and the tablet continues to discharge. I assume the docking connector works both ways and allows powering the dock off the tablet.
I prefer to charge before then though, usually at like 35~19 %. When I undock, I usually leave the dock plugged in to top off, even if it was like 80%.
I've run Prime, currently running Revolver with Blades kernel. When attached to the dock the dock battery is depleated down to 2% before switching over to the tablet battery. What I want is for the batteries to discharge more evenly when the dock is used. The dock battery is going to burn out being run down to 2% every day. Is there a setting I am missing, or a ROM or kernel that allows more control over the batteries?
No......................

the way it works is that the keyboard dock is like a charging pad for your tablet and it charges your tablet in the case that you dont want to use the dock anymore and you want to use the tablet itself as you cant use the dock by itself.
so if you use your tablet some and it goes down to say 80%, the dock will charge it back up so its like 90-100% by the time you take it off. that way you can use it when you dont need the dock. imagine that you use it and your tablet runs out of battery before your dock cause you used it earlier. all you have is a pointless dock left over with battery.
and its not like you cant use the dock when it runs out of battery, when its out of juice it sips battery from the tablet to keep it at like 2-3% charge and its not like the combo uses any more battery in this state.
hope this helped you understand why it does it :]
honestly a great feature. i could hear the outrage of people with dead tablets and fully charged docks.

I understand what you are saying. I just wish there profiles or adjustments that could be made to fit the situation the user is in. Love this tablet anyway.
The solution that I have, is I will generally spend part of the work day with my dock on charge. Somewhere between 30% and 75%, I'll plug in until charged or just stay on charge until near time to leave. This works for me, since when I take my TF with me, I will usually take only the tablet portion, or I will be gone long enough that I want the dock and a good charge.
I'm also considering going down to ~816Mhz or lower max frequency to conserve power when on `extended` time away, to conserve dock power.

Hi Guys,
I remember reading a post about this before but can't bloody well find it
With my tablet docked, they keyboard battery is draining much faster than my tablet resulting in a useless dock fairly quickly i.e. 0% in dock vs 80% in tablet. This seems quite a gap - I'm running stock, not rooted. Is there anything I can do to improve this? I don't remember the charge gap being so vast in my first TF700.
Any advice/suggestions are most welcome.
Thanks.

Been discussed before. Dock still operates at 0%, no need to keep a charge in there. It acts as the sacrificial battery, making the tablet use that power first, so if you so choose, you can continue using the tablet w/o dock or with dock and get the maximum battery life both ways.
Thanks Nick, I thought I noticed my keyboard wasn't working before when at 0% but will give it another whirl tonight. If it does work then bravo on Asus
i recently bought the dock and i also find the battery drain rather strange. i always turn off wifi over night and the battery of the tablet usually stays exactly the same, e.g. if i fully load the tablet before going to bed, i have like 99% in the morning without any drain.
yesterday i went to bed with dock 80% and tablet 85% and wifi off. today i find the dock left with only 40% and the tablet with 82%? is this normal? i guess i have to take them apart all the time over night otherwise it just drains too much
Definitely is not normal - I leave mine docked overnight with wifi *on* and I only get a percentage or two drain...
To start with, 'd look (with CPU Spy) to make sure you tablet is deep-sleeping properly.

That's odd. Maybe some process kept running overnight.
Check that the following are set:
- GPS to OFF
- IPS+ OFF (set it to IPS mode. + drains 10% or some overnight, even when off.)
- Mode to Power Saving!
- Shut down all active processes (taskmanager has this convenient one click clean.)
- Check that media players have shut down properly in the Settings/Apps/Running apps menu. Also make sure they're not still cached (VLC tends to do that...)
I think that this is normal behavior. I notice that after using the device for a while, when I shut it off the dock battery actually charges the tablet battery. The charge light on the tablet even indicates that this is the case. I believe that is by design.

The charge light is indicating the tablet is (primarily) running off the dock battery. EDIT: although this is in essence a correct statement, I have paid more attention to it and noticed the dock does indeed charge the tablet (when not in use) -- it's a few percents, but nonetheless, it charges. Mea culpa..
The capacity of the tablet and dock batteries is different, so discharging under load will differ as well. I guess the behavior you are seeing is by design, and, to some extent preferable to the situation I have had since the beginning: my tablet depletes faster than the dock, at least initially, and that was what most of the early adopters were seeing, as well. This of course led to some discussion.
The behavior we noticed seemed somewhat counterintuitive, since it meant we would have less battery capacity on the tablet if we would choose to undock it -- as opposed to your situation, where you have as much battery capacity left on the tablet as possible when you choose to 'travel light'. I'd prefer it that way. ; )
So, the dock depleting significantly faster is nothing unusual nor anything to worry about. I do have to concede, though, that my battery drain is far less than some in here report -- it has been going for three and a half days with moderate use now. (That's OK, I guess, given the fact that I currently am in nightshifts and do not have to time to tinker as much. Even when I *am* tinkering, though, the batteries routinely carry me over two days, easily.)
My dock and tablet have weird battery usage.
So my problem is really weird I think, but maybe you guys can confirm or offer any fixes. I have tried charging the tablet and dock assembled through the dock port and gotten both batteries to 100%, but then while docked, the tablet's battery drains faster and the dock;s remains at 100%. As the tablet's battery gets to around 70%, the dock's will start to deplete but very slowly. The dock will only go to 70%, and the tablet will drain completely to 1% and then shut off even though the dock still has 70%. I then undocked the tablet and just charged the tablet back to 100% without doing any charging to the dock. After docking the tablet, it shows the tablet at 100% and then the dock at 70%. This time the tablet drains to 1% and then shuts off with the dock still at 50%. What's going on here or is it normal or is there a setting that I'm missing? I thought the dock was supposed to extend the tablet's battery life time??
