is there a way to tell what is the battery level of the dock?
I am also very curious if there is a way to determine how much battery life is left in the dock.
Nope there isn't.
Thats not good

Not something Asus can do anything about either, Android isn't made to be compatible with battery docks. This is a completely new concept so yeah.

Yes and no. Assus could add an api so that the battery level could be read. I know that ANT+ hardware is not supported in android, but sony-ericsson have them in there X10 mini and provide access via an api. My guess is that assus will provide support for battery level in future updates. New concepts ask some time.
What happens when the keyboard battery fully depletes, does it just become unresponsive?

Only way I know how is to plug it into the charger and look at the light pattern. The patterns are described in the manual. Also if it's not plugged in but drops below 10% the red light next to the charging plug will blink red (Asus calls it Orange in their manual).
I tend to disagree with everyone here.
my tablet has been in the dock for 2 days and the tablet was 100 going in and now its 97% i think my tablet might take into account the battery in the dock too. Theres no lighting bolt on the battery

sorry if I'm coming off as a douchebag but it's plain wrong. Asus themselves have said the battery meter does not take the dock into account.

The dock isn't charged. When not attached to anything the dock still drains power on it's own. Fully charge your dock (2~3 hours) and tablet seperately to make sure they're both full, then attach the dock to the tablet and see if the battery meter starts draining right away.

if no lights are on then it obviously isn't charged and the dock is running off tablet battery power.

Your tablet obviously is going to sleep properly and doesn't have any apps causing many wakelocks when the screen is off. What happens is it drains the dock's battery first then after that drains the tablets battery. That's straight from Asus. What you're seeing is an affect of that. They've also said they are working on optimizing the way Android handles this second battery so we'll be seeing strange things with the meter until then.

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.

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.

Does it help if I leave the tablet and the dock disconnected when turned off?
Hey guys,
I'm reading through the dock threads and I see a lot of issues with the battery, but I didn't see anyone with the same problem as me. Maybe it's not a problem, but I figured I'd put it out there just to make sure.
Sometimes my dock will read at 0% battery, then suddenly spike up to the proper battery percentage. It usually happens after it's asleep, then wakes up. Last night I had charged the dock to 100%, then unplugged and plugged into the tablet a short while later. It was reporting 0% and had a flashing orange light. I then charged it today and it held the charge, but still doing the strange 0% to "real" percent thing.
I have both a B60 dock and B60 tablet and I am using Prime 1.7 ROM.
Has anyone heard of this? Is my dock bad? I can still RMA it as it's brand new.
Thanks!
I did a test last night by fully charging the keyboard then plugging it into my tab at 17% battery. When I woke up, the dock had 3% and the tab had 76%. This seems pretty on par with what I'd expect. I just don't want to charge the tab and have it not hold a charge at all.
How do you even know how much your dock is charged?
I use a couple of the dual battery widgets (still haven't decided on one). I sent my dock in for repair on the drainage issue a couple weeks ago. Since getting it back I have noticed that when I wake the tablet up, it can take a long time (Sometimes up to ~5-10 minutes for the dock battery to show the correct voltage). I had upgraded to 3.2 while the dock was out for repair, so don't know if its something with the new dock hardware, or a 3.2 issue.
The other day had the dock reading 0 and even after an hour of use, never did show it had a charge. Thought I was screwed because I had read several threads that said if you ran the dock down to 0, they couldn't ever get it to charge again. Plugged it in overnight and let it set, fired it up the next morning and both were at 95+%.

When you click the notification bar, it says "Docking Connected" and then the dock battery percentage to the right. I'm assuming that is the dock battery percentage... I'm not sure if it's part of the rom, but I think I remember it being there when I was stock.

Thanks for chiming in. I'm thinking this might just be a software issue and not a dock issue then. I'll see how things go over the next few weeks.
Anyone else seem to have dock to tablet charging change in behavior after the V9.4.5.26 firmware update?
Before the current firmware I recall the dock topping off my tablet battery after the Infinity was left idle for a while. Now it seems the dock at best is only slowing the tablet's battery drain. If I reboot the tablet the dock seems to make more progress towards charging the tablet battery closer to full.
I don't quite know if I'm misremembering the old behavior, or this was a firmware change, or I should be concerned about a faulty dock to tablet connection.

Mine beheaves just like yours, but I'm still on .22
When the tablet's battery is empty and I plug in the Dock it loads the tablet
but when I put the tablet with the dock together when both of them are about 70 % then the dock isn't loading the tablet
---------- Post added at 05:07 PM ---------- Previous post was at 04:17 PM ----------
I just found out that the dock has started to charge the tablet when the tablet's battery was going under about 60%
Same behavior here
no reason dock should have charge if tablet isn't full. charge in dock is pointless.
My unreliable understanding is a 0% empty or 100% full lithium battery will have a shorter usable life span than a lithium battery maintained around 75%. I can understand that trade off for the dock battery if that is what is happening.

Last night I noticed that the tablet says "charging" while in the dock, and the dock depletes. It seemed pretty slow and the dock seemed to drain reasonably quickly. From what I've read, its supposed to drain both at a slower rate.
Personally, I like the idea to have the dock charge the tablet. It just makes more sense.
Mine was still not charging the tablet at 76%, now I docked it under 66% and it's charging, so I believe it goes on somewhere around 70. I think it was somewhat sooner under .21 and .22, but after installing SwiftKey (crypto-ad) I'm rarely using the dock when not using the shell (but hey, I'm on holiday!).
Edit: Stopped charging at 90% (the dock is 60% now, so ~25:40 ratio, btw), seems reasonable.

Then no charger should ever charge past 75 %. Now if you want to argue not depleting the dock past 10% i would buy it.

It does make sense, switching charging off and letting the battery drain partly allows the battery in the tablet to have a longer life span. It usually let's it drop 20% or so and then charges it for a certain amount. If you keep charging from 90% to 100% over and over, it depletes the life span of the tablet's battery.

With Lithium Ion though, that shouldn't be an issue from what I understand. NiCad's, and to a MUCH lesser degre NiMh's will get that memory effect, but Li-ion's are immune to it, in fact they do better when kept charged up.

That is true, Li-Ions are much better off staying between 40 to 80% and don't have the dreaded memory effect of NiCd and NiMH. However, when you get close to 100% when charging the voltage is also very high, which can shorten the lifetime of the battery in the long run. That's also what KilerG is saying.
It's better for the battery to just let it discharge a bit, then charge it up again. Maintenance charging it at 100% will require a lot of juice from the dock when the tablet is in use. The charge efficiency is greatly lowered when above ~80% since you need to continue increasing the voltage, but decrease the current to avoid overheating and damaging it.
My dock is currently at 78% battery while the tablet is at 77%. It's been on battery power for about 2,5 days now, I've only used it for a short time lately as I've been busy with other things.
Last time I took it off AC and it was more actively used, the dock depleted more quickly while the tablet was being topped off by the dock every now and then. Gives the tablet a lot longer usage, although you could end up with an empty dock while the tablet is still running. That's fine with me, the dock isn't much use without the tablet.
Edit: Actually, the battery indicator wasn't updating it seems. I undocked and docked again and the numbers went from 78% and 77% (dock and tablet) to 63% and 85%. Not sure why the battery status isn't updating properly. Might just be a one-time thing.
From the Asus forum:
http://www.transformerforums.com/fo...attery-related-matters-transformer-range.html
Excerpt:
TF201/TF300/TF700
* The charger charges the docked combo all together.
* When fully charged, the tablet uses the charge first, then the dock charges the tablet. The idea being that the dock battery will be depleted while maintaining the tablet battery. See below...
The way the combo works is that the dock does not charge the tablet continuously. I believe the percentages are along the following lines..
Dock 100%
Tablet 100%
Tablet uses charge until the level is around 70%. At this point the dock will recharge the tablet back up to around 90%, if the tablet is not being used.
If the tablet is being used, then the dock "powers" the tablet, balancing the charge rate with a direct bias to ensure that the dock will eventually drop to 3-5% with the tablet at around 90%.
The dock shouldn't allow itself to become any more discharged than 3-5% & neither should the tablet. Android will warn you when the tablet drops to 14%.
The dock will still continue to function until the tablet shuts off.
----------------------------
However, this is not my experience, which is why I was researching it in the first place. Dock charging behavior is inconsistent. I started seeing that the dock was no longer fully charging the pad w/o a cold boot recently (I'm still on ICS, rooted). Then it would develop the problem again after a short time, even when plugged into AC. Right now I'm plugged into AC. At start my dock had no charge and the tablet had about 60%. The AC charged the dock and the dock passed charge to the tablet until the tablet had 100% charge - correct behavior, I believe, since this is what it did when brand new (it's still quite new). Many have posted about the dock not charging the pad over time. I think there's a hardware issue of some kind, or system software problem since it temporarily will correct after a cold reboot. Or maybe there's a software conflict. I've been uninstalling stuff to free memory.

I'm having this problem, too. After charging both batteries to 100%, I unplugged from AC, and I've been using the pad for a couple of hours. The battery indicators still say 100%. I think this may be a hardware problem (or an API problem) because Dual Battery Widget reports the same. Undocking and redocking did not help. I suspect only a cold reboot will help. Perhaps my prior problem was a battery indicator problem, and not a charging problem, as it seemed.
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??
