[Q] dock battery meter?

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?

No keyboard can be dead gets power through tablet

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.

sure....then im incredibly confused by this then....closing the lid when docked must practically turn everything off cause im still at 97% with 37 hours uptime.

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.

[Q] Dock battery drain - Anyone not have this problem/sucessfully repaired by Asus?

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.

[Q] Is it bad to always have my Transformer Docked?

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%.

[Q] Battery or charger at fault?

I have a locked & unrooted WW TF700 & genuine dock on JB 4.2.1.
A week ago I started to notice an issue where the tab would constantly drain whilst it should have been asleep. Overnight it would loose ~30% instead of ~2%. I tried a few settings, but couldn't seem to solve it. I decided to do a factory reset because I haven't done one since I last upgraded to jelly bean. That appears to have cured that problem, but has created two more.
The first problem is that I can't seem to charge the tab over 81% when being charged directly. If I then plug it into a fully charged dock it will charge to 90% but no more, even with the charging cable in the dock.
The second problem is that the tab now decides to shut off at about 30% battery left. It won't shutdown as normal, just go blank and won't boot up again without being charged a little first. I have read threads about artificially overcharging the tab, but a symptom of that is the battery level will remain at 100% for hours before starting to drain normally. My tab won't charge to 100% and will start to drain immediately after removing the charging cable. Regardless I have tried to drain and recharge overnight with the tab both off and on but the tab won't charge past 76% overnight in either case. Restarting multiple times doesn't help at all.
For the first issue I started to suspect the charger may be at fault. This is because if I charge the tab directly, it will never get past 81%. However, if I then plug it into the freshly charged dock it will charge upto 90%. I understand that the dock will never charge the tab past 90%, unless it is plugged into the charger. Does it assume in my case that it isn't plugged in to a charger even when it is? I should mention I am using the original asus charger. Frustratingly I can't just use my phone charger to see if it solves the problem due to the 15v of the asus charger. I have noticed a slight hum/buzz coming from the charger but I can't be sure that it didn't do that before. I have had issues with the internal connections not be pushed together quite right before and getting no charge out of it, but 'clicking it together' a bit more firmly did the trick there.
Even with an overnight charge, plugged into the dock to get it to 90% I now get terrible battery life. Roughly 30mins per 10% juice. Previously I was getting around an hour per 10%.
Does anyone have an suggestions for me on how to eliminate the charger as a problem, or say doing another factory reset on a 'full charge'? The only other thing I can think of is to let it drain, give it enough charger to turn back on, then turn it off and leave it unplugged overnight (I saw it mentioned in another thread). I really appreciate any help you can give before I have to try the dreaded warranty route!

Try this with it undocked. Let the battery discharge to zero, and leave it 24 hours.
Then recharge it fully. This seems to cure the battery calibration memory issues.most us know how you get on.

Luckily I have located an Asus charger to borrow and hopefully find out if it is just my charger or not.
I also tried out CPU-Z and the battery is reporting as only having 7mV. I'm sure that can't be correct as my HOX+ is around 3500mV, and 7mV just couldn't power anything. I don't know if this is just CPU-Z issue with reporting correctly, or a clue that there is something not right with my battery? Has anyone else tried CPU-Z or know what the mV should be roughly, fully charged say?

Unfortunately a different charger didn't solve my issue :'(
I've posted a screenshot to show what is happening. I'll try draining the battery flat and leaving 24 hours to see what happens then. Luckily I still have two months left on warranty.
Pretty annoying because everything else the tablet does is fantastic. I replaced my laptop with it and use it daily for everything.

Unfortunately things have become worse. I tried using the tab until it died (at around 50% battery this time...) and left for 24 hours as suggested. Unfortunately now I can't get the tab to turn on or take a charge at all. I have tried holding power button down, with vol up/down, for over a minute etc. Tried the reset button all numerous times with no luck. All I get is the LED blink twice when pressing the power button and this only happens when the charger is connected, otherwise nothing.
I have the phone number for Asus support and will be giving them a call tomorrow. I'm so glad I never unlocked my device!

Leave it for 24 hours not on charge first then try again. We've seen this happen so many times - the fix is to let it discharge completely.

Thanks Sbdags, I appreciate your response. I've read numerous threads tonight with similar issues. I did try leaving the tab for 24 hours completely dead overnight last night. I'll try it again (I don't know if the battery is dead or not currently) but I'll leave it unplugged as there is nothing else for me to do with it anyway!

OK, I thought I would complete this thread.
After leaving my tablet for a few more days not on charge I could seem to get no life out of it whatsoever so went down the RMA route and the result of that is in the following thread;

[Q]

So a few days ago my device started to shut down at 15-20% battery. I use an battery app which makes me se how many % it is left on the battery and the original charge meter seems to be consistent with the app. It also doesnt let me start the device again unless I have a charger in. Another wierd thing is that i am not sure it is charging at all because it does not show in the icon sometimes... (I am writing this while making these observations )
I use the docking station mostly, could this mess things up when i only use the device itself?
I docked the device at 16% and after a few min of youtube it just crashed like before, not a regular shut down.
Is the battery busted because I use it constantly for the past 8 months? I mean I put it in sleep mode when I dont use it but I almost never shut it off.
Wierd, I think it stops charging the device if you leave it alone for a while. It shows it charges the docking station though. I would try other power outlets but somehow i feel it is connected to the first issue I had.

Sorry stammis but neither your topic nor your post makes much sense to me.
Your problem is with the tablet docked or undocked?????
It may be a battery calibration problem. Some users have solved this by letting the battery drain in sleep or standby for a day or two.
