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!

Is that the last setting in that section? I have that box checked.
Hmmm, I don't know then. What is your wifi sleep Policy?
My wifi is set to never.
I last charged my tab on thursday night, its between mostly idle since then(like 3 hours total use since then) still have 77% on tab and 37% dock.

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.

I am obligated to ask you this question...
Are you absolutely certain that your keyboard dock has a significant amount of battery, thus enough to charge or "transfer" its power to your TFP?
Mine is not having this issue, nor has it ever.
Always witnessing the arrow symbols indicating transfer.
Sent from the last remaining Prime; Leader of the Autopads.
It had 55% at the tim. About 10 minuteslater it started the transfer.
Sent from my Transformer Prime TF201 using xda premium
im confused. how is this not normal? After the tablet drops below 70%, the dock charges it up to (nearly) 95ish %. Then it drains again, and the dock charges it again...?
Are you getting something different or weird?
The power transfer behaivior on my prime TF201 changed when I went from HC to ICS .13. From what I can tell currently the dock supplies all the power and will drain down to 1% prior to having the main battery in the tablet drop below 92%. Prior to the update they would both drain down at the same time with the dock running ~10% lower than the tablet.
This might be tablet version specific as the B1 serial number tbalet that I had prior to it bricking with the ICS update would drain the tablet first then the dock. I exchanged my tablet and now have a C1 series serial number. I dont know if this helps

I think you didn't know how your tablet worked in the first place. This is the way my tablet has worked from day 1 with HC and with ICS. The tablet gets down to around 70% and the keyboard dock recharges it. In fact there are 5 or 6 threads already out on this forum about this topic. If your tablet is working as described here now, then your tablet and dock are working as intended.

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?

Hi boys and girls!
I bought a TFP (with sn: C3O) less than a week ago from NetOnNet in Sweden. I'm loving it! Damn what a piece of hardware . But I did notice one thing. The only problem I had with it. When docked and sleeping, the battery would drain insanely fast!!
I found that many ppl pointed at the option; "Stay Awake - Screen never sleeps while charging". But making sure that it's unticked doesn't seem to be enough. After digging some more online. I found that ticking it and then unticking it again made all the difference! . And it did for me too!
I went from losing (not actual numbers) 12% battery/hour to losing only 0,2%/hour. Hope this info helps. And if it does, spread the word! .
Edit: I polished the numbers abit. My Prime is crazy efficient nowadays, and have been ever since the fix . I just wanna add that you MAY have to redo the fix after installing a new firmware.
I'm sorry but where exactly is this stay awake option?

Yes, below 70% the dock kicks in and drains to 0% or something like 30%.
I think that depend on how low the tablet was and I think the dock stops charching the tablet when it has reached around 90%?
Shis really sucks, I would like to be able to stop the dock to auto-charge. That way I would be able to keep battery levels identical as when undocked and the tablet should only be charged when it's docked and in use.
Will this option ever be possible in stock or custom rom? Or is this "hardware-coded"?

For me the problem existed because the setting, Stay Awake, was "stuck". Which means that when the dock is connected to the tablet. The tablet thought that it was being charged, so it stayed awake. Using up lots of battery 24/7. Even when it was just idle/locked. And when the battery in the tablet dropped below 70% then the dock started charging it.
Problem is that since the tablet was using up lots of power, the docks power got drained. Cause it never managed to get the tablets power to 90%. At 90% it would've stopped charging it til the tablets power would've dropped below 70% again. Whew. Hope this answers your question .
I'm thinking that you could have the tablet and dock connected but instead of having them idle/locked you could turn them off completely. Should work. But that's not very practical now is it? =/.
Thanks will try this out!

I believe there is an option in the dock settings to change what percentage it starts to charge the tablet I'm not positive though because I don't have my prime in front of me but do remember seeing something about it.
Again I could be wrong but I'm pretty sure you can change it.

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...
