NORMAL Dock + tablet battery life

---

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,

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