Hi! I got this type of question about hardware of Galaxy Tab 10.1: does often putting tablet in dock station (normal without keyboard) has an influence on battery life in future? For example if i like to use it as photo frame or bedside clock. Does the battery life will shortens?
If you bought the Sammie desktop dock then it should not shorten your battery life. It is using the same charger that you bought with your tab. Also to be put into consideration if you broke in your battery before you started using the dock. Pretty much using your tab till battery is low then charge it back up. I have the dock and I too been using it the same way as well. I have not seen any changes in the battery life.

I had the old transformer with the battery drain problem. I haven't seen anything posted on the new prime. Is there a drain when plugged into the dock? Also, I have one of the defective wifi tablets... annoying as hell. Is it a hardware issue or has anyone heard of it being just a software issue?...I want to know if I need to take it back or not. because if it is a hardware problem I am returning it for sure. thanks
ASUS Transformer Prime Keyboard Battery drain
We have same issue: even when we disconnect the Keyboard from the Prime, the battery in the keyboard drops overnight from 88% to 2%
Basically renders the keyboard battery useless..

Are you serious?
My Battery doesn't drop more or less than any other non-used Li-Po battery...
I can't see any non usual drain on my dock.
One of the real improvements with the Prime is the good battery power management. I now just leave it on the couch and I know the battery will have lots of juice the next I pick it up.
If yours is acting like the original Transformer, you have a problem.
Bye.

wow. send that dock back quick! @[email protected]
I got two Primes + two Docks, neither docks lose a notable amount of power if left unplugged overnight, a couple of percent at most.

Agreed, I also have no issues with battery drain my Prime and dock have amazing battery life. If I leave the dock all week unused, it may have dropped by 1% when I come back to it.

Doesn't the wake up function cause battery drain on the dock? Try disabling it in setting, worth a try.
Just to clarify the scenarios here: (idle battery drain)
Plugged into dock, power saving mode on: 3-4%/hr
Tablet NOT plugged into dock: 1%/hr (tablet) & no appreciable drain on the dock.
So, while on the dock I do have significantly increased idle battery drain. I don't really understand why this level of battery drain exists even with dock power saving mode enabled.

Imho the problem is that even when the mobile dock battery saving is enabled... it only disables responses to keyboard. The touchpad is still fully operational and wakes up a sleeping docked tablet when touched
I think that the 70-90% is kind of awkward and highly overuses the tablet inner lipo charge cycles.
Imho Asus should make a utility that alows the user to decide wheter:
The tablet runs from the dock battery with no charge of inner battery
The tablet is being charged from the dock up to 90% as it is reasonable for charge process
The tablet runs on it's own battery without recharge from the dock even though the dock has some juice left.
Any other scheme proposals are welcome .
Above should however vastly improve the quality of our batteries.
At least an option to disable the charge from dock to tablet is imho a must have

could be possible via kernel mods... but you are right, i kinda dislike the current method too.
It's stupid that once I disconnect 2 fully charged modules the tablet battery gets few extra charges from the dock.
That way I cannot treat the dock as a backup battery for running or recharge for when I it is really needed.
Someone please stick this thread and make another offensive on Asus.
It would be sad to root/void the warranty just to get such a must have when it should be done on stock.
agree in 100%
Could someone explain what is the current 'charge policy'?
As as owner of the original Transformer and the headaches it came with the dock discharging charging the tablet all the time and dealing with a dock battery that had issues being registered as charged or recharging (I RMA'd and others had the same issues as well), I love, love, love the way the new charging method is.
With that said, I think choices are good and having ASUS provide a way to let you use it how you want would be nice.

Instead of always charging from the dock, when docked in it only starts charging the tablet when the tablet gets to around 70% or so.. then it charges the tablet up to around 90% and then runs off the tablet and the cycle continues. So both the tablet and the dock discharge X amount at a time.
Hm, can see both sides to the argument, depends on whether you look at the dock as a battery booster or just to aid the tablet.
A utility would be a good idea to let the user choose, just have an option in the 'ASUS Customised Settings' menu.

Does this mean that when tablet is docked, it sometimes uses tablets own battery and -not- dock battery even when dock battery is charged!? What is the point in that?
I thought that the dock gets discharged first before tablet touches its own battery.

The point maybe to address the issue with the dock in the original design where it did discharge first and causes some issues. It's still using the dock battery when docked, just a different method from how the first one was. You'll still get 16 hours or whatever out if you use both together.
Either way, it's not getting to a point on the tablet where it's going leave you with like an hour left to play with should you undock it.. mid 70s seem to be the lowest it will go so if you do go all day with it docked and in use, the dock battery will get to 0 and the tablet will be around 90
yes there could be a time where you take it off the dock at 75 with some juice left in the dock.
Just to me it's a lot better coming from the original Transformer.
I can understand some folks who would rather just use dock's power first and then the tablet. But again, as an owner of both and seeing how both work, for me this is a better way
If the dock has no battery but the tab has loads, and you plug the dock in... would it work? If no, then I can see why it doesn't discharge first, if it does then there really isn't any point.

Yes it works fine. Had this issue on the original one all the time.

Fully charged both the dock and tablet, then connected them.
Noticed the docks battery was depletiing first.
Put the tablet to sleep and noticed this morning the dock battery is at 0%
and it has a exclamation beside it.
Is that a problem to continue using the dock when its battery is 0%?
Nope, dock will work just fine. Will not cause any damage.

however if your dock is draining the battery on its own like that it could mean other problems. My dock charges and stays charged no problem, when i use it it seems to work properly, never had any fast drain issues with mine.
I would see about getting a replacment if i were you.
I think he means dock battery drains before the tab battery is drained, which makes sense since the dock charges the tab so of course dock will lose its charge first

My only concern was the ! mark next to the 0% dock battery status,
but it seems that is how it is designed to work.
hi guys,
so when i'm at home i found myself using the prime more and more and often with the dock for writing posts and also for using it as a stand while watching youtube or playing a game with gamepad.
Since the dock empties itself as soon as the Tablet dropped to ~75% i'm a bit concerned. I know that li-po batteries dont like to stay at low voltage/low charge for long times.
So the Tablet is at 80% and the dock is empty. 80% can mean days of medium usage, so the dock will be at 0% for a pretty long time.
Should i prevent that and always charge the dock as soon as it runs out? Would be nice to know how the dock handles voltage and charge. It could also be that it still has plenty reserve charge when it displays 0%..
any thoughts?*
Shouldn't be a problem. The dock is going to use the power of the tablet to power itself.

i don't think any of us have had the TF201 long enough to have a dock battery degrade, maybe TF101 owners can advise. but your concern is fundamentally sound. the dock has a lithium ion battery in it like any other. all li-on batteries are prone to having their cells dry out if they spend a lot of time fully discharged. the net effect is that the battery will diminish it's capacity over time.
asus made a good design decision with the TF201 by not having the dock charge the tablet until the tablet depletes to 70% capacity, because li-on batteries also degrade when constantly being held at 100% charge. but imo they should have put in another threshold for the dock battery, say at 25%, where the dock stops charging the tablet until the tablet gets dangerously low. in lieu of this, my personal opinion is that it is wise to give the dock a charge (or disconnect it from the tablet) once it dips below 20%.
Hey guys,
My dock has been acting kind of weird lately (see my thread in the Q/A section if you're curious - dock battery showed as 0% even when charging). What I'm wondering now is how others are doing with battery life in terms of the dock recharging the prime.
When I first got the tablet + dock, I used to be able to recharge the prime 2-3 times when the tab dropped to 70%. That would usually drain my dock battery all the way.
Fast forward to today and the past two weeks...My prime just finished recharging my tab up to about 90%, while it was being used to annotate lecture notes with some mild browsing and emailing in the background, the dock dropped to about 60%. This is what's concerning to me...It seems to be taking double the battery from the dock to recharge it to about the same, or less than, what it did before on the dock.
My use today has been pretty constant. I recharged both to 100% last night, and when I opened it up today at 12:30 pm, the tab was at 96% and the dock at 98%. Since then, my dock dropped to 88% while the tab drained in the same time to about 70%. It then started to charge my tablet to about 90% but the dock dropped to 34% where it is now. I have been using this constantly for the past 3.5 hours.
Here are my concerns, which I hope you guys can help me address:
Is this normal battery drain for 3.5 hours of moderate-heavy use?
Is this drain software related? It seems to have been fine way back on .11 (I'm on .15 now)
Is my dock battery shot? (ie should I RMA it)
Does the dock battery drain EVEN MORE if it's recharging the tablet while you're typing notes, etc on it?
Does a USB peripheral (ie wireless mouse) increase battery drain SIGNIFICANTLY?
I would attach a battery screenshot, but my settings battery menu doesn't have it tracked since it's docked.
I'm hoping this is a meaningful and useful thread so please try to avoid stating something obvious lol
Thanks guys

What performance modes, brightnesses are you using? Can you give us more info about what would be draining the battery?
It's quite possible your prime could be using a percent of the dock for every percent it receives, making it seem like your dock isn't working well, when in actuality it could be your tablet.
.15 was a battery killer for me, since I put virtuous on my prime and underclocked the cpu as the battery gets lower, it's fixed my battery life.

Sorry - forgot to include that. I'm on the normal regular mode with auto brightness. With SetCPU, I had it on On Demand up until this afternoon around when I wrote this post. Then I switched it to interactive.
And as for your second point, I agree that it's possible that's what's happening, but because I'm using it for hours on end, I'm not quite sure if that's what's happening, part of why I started this thread.
Have other people seen improvements from .15 to Virtuous?

Another question, along the same line.....If the tablet's battery is low, the dock is fully charged, and unplugged, will the juice in the battery partially charge the tablet, so that I can remove it from the dock and use it separately until I get to a charging station? Or will the tablet ONLY run off of the dock's battery?
Thanks,
Bob......impatiently waiting for my champagne dock to come

Yep, the dock charges the dock when it's plugged into the tablet.
