I got my prime last week and I keep my prime docked all the time except when I play games. This is because I dont have a proper casing for my prime and docking it would be the best way to protect the screen.
My question here is, will docking it 24/7 disrupt the battery life of the tablet?
Since it charges the tablet at random intervals, is it bad to constantly charge the tablet from the dock?
It doesnt charge randomly, it starts charging at around 70% until 90%, which is actually a good range to charge Lithium-Ion batteries! So you should be fine, relax

I am in same situation as you. I have ordered the Dual Case made by Minisuit from Amazon but I won't get it until later in March. I keep my Prime Docked 99% of the time and turn it Off and Keep on Charger when not in use.

true story
my prime is always docked, only when I'm playing games or occasionally while surfing on the sofa will I take it off the dock
The one annoying thing about keeping it docked is I haven't yet got any good data on what the battery life of the docked Prime is. The data shown in the settings only show the time that it is undocked or when the dock has run out of battery.

FYI there have been a few reported cases of screens being cracked while docked without any drops or accidents. Some people seem to believe that the dock can put pressure on the screen because of how it closes. So keeping it in the dock might not actually be the best way to protect your screen. I never had the dock so I can't speak to the issue but check out:

Same here.. but I'm adding in a screen protector, just in case.. not sure if that'll help much if the cracking is pressure related, but I figure what the heck.. why not?

As well as the nook I also have an asus transformer and a bkackberry Playbook.
The Nook and the transformer seem to have similar standby time but I realised today that the Playbook knocks spots of of both of them. The playbook has been sat on the table in the living room for a good few days and it's been just in normal stanby with wifi still on (not sure if it shuts off when it sleeps). I picked it up expecting it to be flat only to find that it still had 30% power left!!! The nook just couldn’t do that length of time I'm sure, if I leave it it may last 2 days I guess.
What sort of standby time are you all getting? Do you set wifi to disconnect when it sleeps?
Woah, that's definitely NOT the standby time I get. I've set my Nook Tablet aside for a full day without use and the most I've seen it drop is 1-2% of its battery life. In fact, I haven't even charged it the past 1+ week and it's still around 70% (and that's with minor reading inbetween at low screen brightness and WIFI off).
I'm pretty sure I could set my Nook Tablet without touching it for a week straight and it'd still have a majority of its battery life like a champ.
The only thing I can possibly think of that's helping is my use of Juice Defender I have running in the background, but its main battery saving function usually involve s around minimizing WIFI activation as far as I can tell, and that is somewhat moot if I have it off.
yea I wish my NT could sit around not charging that long but really no complaints here. I get a good day out of it

Well from what little I know about the two tablets they both have the same base chipset and very similar screens so Nook 'should' be able to do the same as the Playbook so I'm definitely going to look into it further
well we need to find out what the secret is lol
I get days out of my NT when I don't use it, though even when I do use it I barely seem to put a dent in the battery percentage.
I'm so used to my old laptop and many phones over the years that I had to try my best to squeeze a day out of, that this thing just blows my mind sometimes.
My mom has a Transformer and she seems to have similar battery life to me, going on days without charging.

With my transformer it'sbecause eit dien'st sleep when connected to the dock, it's a known issue and if I got off my backside and contacted Asus they'd RMA the dock and fix it. If I disconnect the dock form the screen I get days out fo the screen even if I do use it a bit
Nook just doesn't seem to compare. Not yet anyway...
I'm on my fourth day, without a recharge. I haven't plugged it into anything since I started using ADBWireless. I can't estimate the screen-on time accurately, but I've read over 200 pages of memoranda and have been messing with my widgets and layout a fair amount. It's at 36% right now. I don't plan to plug it in until it dies (for science!).
anyone have any thoughts on this? I'm getting poor battery life as well. I'm running current widget and when I come out of idle there is quite a bit of current being drawn (200ma).
I'm rooted running go launcher.
Hadn't used my dock for a couple of days and plugged in my Prime tonight to see how the dock held its charge. I was impressed to see the dock at 98%, which is right where I had left it. That's about perfect.
Just thought I'd make note of a significant positive.

Yes, that's something that ASUS needs to resolve. I get about 1.5%/hour usage when the Prime is docked and closed (and thus on standby), vs. about .25%/hour on standby for the tablet by itself.
That's better than what I get with my original Transformer when it's docked, which is closer to 2.5%/hour usage. But, it would be great if ASUS can figure out a way for the dock to not stop the tablet from entering deep sleep.

I don't see it as that much of a problem. If there's truly something about the dock that makes deep sleep on the tablet impossible (I have no idea if there is or not, and it really does remain to be seen), it's not an unreasonable solution to simply store them separately. Even carrying them separately isn't a problem, really.
I do hope that ASUS can enable deep sleep when docked, but if they can't it doesn't really reduce the usefulness of the dock for me. In fact, I use my tablet by itself the majority of the time in any case and thus tend to keep the two separate.
The fact that the dock maintains its charge when undocked is far more important to me, and it does that quite well.
Just a guess but I would assume it doesn't enter deep sleep because it will turn on the screen when you open it. If it is docked and you close it, the screen shuts off but it still needs to monitor the dock to see if you open it again. It would be nice to have an option to have it conserve power (as if it isn't docked) and you have to manually turn the screen on again.

I'm not saying it's the end of the world, but one of the attractions of the dock is to make a clamshell shape that will protect the tablet and keys during transport. sucks if it will drain the battery whenever you want to take it somewhere.
Mine does go into deep sleep, make sure in asus customized setting you put it in battery facet dock mode, then the keyboard doesn't wake the tab.

I didn't know that. Very helpful, I'll check that
I have something setup wrong because my tablet sucks my dock dry in about 3 hours in use - it just never stops pulling the charge from the dock. I only let them sleep together once and it was a disaster ......dock was drained, tablets had rebooted I suppose because it was in some sort of different "mode", it still had life, but it was alien like life!

I'd been wondering how well it would hold a charge while docked, so last night I fully charged both the tablet and dock then left it closed from midnight (UK time.)
It sat on my desk like that until I got home from work at 17:15 this evening, opened it up and the dock was showing 99% and the prime 98% full charge.
I've not changed any of the power settings or docked settings yet, so that's running out of the box (post updates of course.)
Of course it's possible the battery indicator isn't accurately reflecting the amount of charge it's used, but based on those numbers it doesn't seem to be a problem.
Somewhat anecdotal evidence, I'll test it out a bit further this week and see if its actually entering deep sleep (presumably it is.)

This has been my experience as well. The dock does not seem to keep the screen any more awake than when they are not connected. I do love how the screen automatically comes up when you open it and turns off when you close it.
Man I love the two of these things together.
I have the Asus setting checked but my tab is like a vampire and sucks the dock battery dry in just a few hours time. There needs to be a deep sleep setting. It isn't really practical for me to disconnect the dock every time I stop using it. That takes away a good part of the portability aspect.

Do you mean when the Prime is completely charged (which is what this thread is about) or when the dock is charging the Prime? Because the dock battery IS smaller than the Prime's, and thus it will certainly discharge at a faster rate when charging the Prime's battery (until it runs out, of course).
Indeed, the dock shouldn't discharge AT ALL until the Prime is at 70% or less. So, if your Prime is 100% charged and it still sucks the dock battery dry in a few hours, then you're experiencing some other problem.
Again, this is about the Prime and dock both being at 100%, and whether or not the Prime enters deep sleep. It's not about the impact on the dock battery when the dock is actually charging the Prime from a less-than-70% state.

As I said in the post just before yours, if your Prime is at 70% or less, your dock will charge it which will definitely discharge the dock pretty quickly. If your Prime is at 100%, then it shouldn't be discharging the dock at all. If it is, then something's broken.

Hey!
I know that it's never a good idea to leave full or empty batteries just stay without use for too long. I don't use TF201 every day and I have it shut down when I don't use it, I am wondering how the battery should be managed and if any of you have any experiences with maintaining your previous devices, like TF101 or others, in similar conditions.
I charge the device after use and then it stays that way a day or two without use due to me not having lectures or enough time off work to play with it. When I do play with it, I don't use more than 20% of battery life and then I dock it with keyboard again (which charges it again even if it is turned off, which is really nice).
Are there any bad side effects of having the device powered off and not used for a day or two? Or letting the keyboard charge the device while it is powered off? Or leaving it in charged state for a few days?
Since I cannot change the battery on TF201, I am super OCD about the battery situation to make sure it works properly throughout the ~2 years I'll be using it.
Thanks!
I let it drain completely then recharge it. I don't power it off, just let 'er sleep in between work, driving, eating, etc.
Moderate usage will give me a couple days worth out of it. Charge during sleepy time, wake up, disconnect, repeat.

Really good article, thanks!
Problem is that TF201 is a special puppy, since its dock recharges the tablet even when tablet is shut off. It's not recomended to keep the battery 'full' nor 'empty' and problem with TF201 is that it keeps tablet full or drains the dock while keeping tablet full, even if tablet is shut down.
I am just wondering if this behavior is bad for battery life in the long run if I don't use it for a few days (I certainly won't keep it 'on' for days and not use it, this will certainly make it go through more recharge cycles in the long run).
That article is good for managing a single-battery device, but since tablet with dock takes over a lot of charge-or-not decisions, it's a little different.
It's basically question about which is worse, going through definite amount of recharge cycles quicker because it is on and needs to be charged every now and then or letting it shut down and used when needed like a laptop.
Maybe I'm thinking too much and it doesn't really matter, but it just made me curious since I never had TF101, so I can't really rely on that experience.
We can buy the TF201 battery, can't we?
If yes, I don't think you should worry much.
Within a year or two, the battery should be still in perfect or near perfect condition.
If not, then buy a new battery.
By that time frame, most of us would have been buy a new tablet anyway
Make sense? no?

Is there a way to signal the keyboard dock to start charging only when the tablet has 20% charge left?
I leave the dock connected all the time and the tablet is constantly being charged by the dock.
the lithium ion battery is fine you can let it sit for months and months, you can charge it every 5 minutes, you dont have to let it drain out or manage it just let it do its thing!
Hey guys,
Has anyone figured out a way to limit the charging from the dock to the tablet? As in not for the tablet to charge at 75% battery life, to drop it to say 25% the only charge to 50% to try and preserve the life of the batteries, as it seems the tablet will lose battery life due to a 'constant' charge
like a laptop you can set power settings up so that your laptop doesnt charge unless needed when plugged into the power source.
I just want to know if it can be done

I honestly never thought of this, but I gotta say that's a really good idea. What's the point of charging through the dock if eventually, the battery in the dock is gonna run out? I would love it if anyone could figure this out.
Likewise, i know it's somewhere in the power settings yet its fnding out how to do it, and hopefully you dont have to root it or be running a custom rom, if it could be an app install that does it even better, there are some apps that look at the power consumption yet this one would be to turn off / edit the charge protocol

By charging from the dock when the Prime runs down to around 75%, it keeps the Prime charged up longer as in for around 18 hours instead of the 12 hours the tablet alone is rated to deliver.
Even if the keyboard dock becomes completely depleted, it will still work fine as it draws current from the tablet's battery even while it is "charging" the tablet.
The battery in the dock is only there to charge the tablet, it serves no other purpose.
I interpreted the question as 'this mode of operation is bad for the battery cause it can only cope with XXX charge cycles'
I think it's a limitation in the charging circuit that makes it impossible to run off DC input only (with the battery offline), and the battery technology prohibits a constant float charge of the cells.
It might be possible to tweak the end-of-charge current to closer match the 'on' consumption of the tablet (but in what state), so 95-99% charge takes much longer, but probably only in the kernel. It's not worth the effort for my money...

Just about a week ago, I noticed my Prime's battery wouldn't charge above 74%. Sometimes it reads 63% and won't charge any further. The keyboard can go to 100% but prime stays at 74%. I have drained the battery fully, but it still only goes to 74%. I'll be doing an RMA for my prime in a few days (wifi, camera, mura).
Is this software or hardware? Should I just add that as a problem alongside the wifi, camera and mura? Thanks.

What did they repair in order for the tablet to charge correctly? Before I had mine sent in for repairs due to an accidental brick; mine had also been showing some inconsistent battery readings. The tablet would show a certain percentage, but stay at that same percentage for about a minute, while it had eaten up about 3-5% from the dock before there were any noticeable changes in the tablet's overall charge.
AW: Transformer won't charge above certain battery %
Have you tried loading the Prime overnight while it is switched off? I do that from time to time, and until now it has always worked to get 100% charge back. Never could get completely rid of the problem though...
