Check out this thread and keep checking in, I don't think we're totally finished with this:
>>> I have a 2014.03 TF701T bought only 2 months ago. I had rooted and applied CM11 and tried 3 nightlies. My battery use was TERRIBLE ... I finally found the forum mentioned here last night about 9pm (not normally up at 2am, berndblb ! - but thanks for replying here ALSO too).
I RENAMED the two "so" files to xxx.so_bad in the two folders:
Previously, leaving it in NO WIFI, NO GPS, mode and asleep over night, left BOTH batteries nearly drained.
Almost all "battery drain" showed to be AndroidOS.
After the fix, same EXACT conditions, both batteries show 100% this morning !
I am proceeding to turn back on the WIFI and repeat - but it looks like this is solved except for breaking what ever those files were doing.
I will only post back if I see an issue with this fix.
Thanks guys - I had spent 3 or 4 days on this over the last month and was very disappointed. I am now elated - because I really do like the hardware.
A bit off topic - but had also bought a Poetic "leatherette" three piece folding "portfolio" to kept and protect the unit in while traveling. It is built for the DOCK also which is why I am mentioning it.
It seems a nice "idea" - but it is QUITE bulky because of the three folds and initially I thought it was the cause of the problem with disconnecting from the dock - but later found it was not.
The other problem is that the "good" camera is completely blocked - although I really never use a camera on a tablet - preferring a "real" DSLR or my call phone in a pinch.
The Poetic case does seem to protect the unit about a well as you could expect and looks reasonably nice.
A one fold, less bulky case that I bought for the TF700T (without dock) is in some ways better (except for no dock) and the following issues: Because the charger connection is on the bottom of the tablet, to use it in the case while charging, you have to flip the screen upside down - this "works" but the off/on button is then on the bottom and inconvenient. Also, it is not that easy to get out of the case.
Although the original manufacturers would charge you considerably more (most likely) for a case, I would prefer that there is at least one "integrated into the design" case option.
