[Asus Transformer TF700] collindv:
Here are the facts of my case as I know them. I am presenting them because they seem to contradict many of the theories going around regarding this issue. I am willing to admit that my situation might be different than everyone else’s (hardware failure?).

1.	My tablet is a TF300T

PAD Version: PAD-EC20T-0216

MobileDock Version: DOCK-EC20N-0207

2.	My battery drain started when I upgraded the bootloader in order to run Cromi 5.x

3.	I had the battery drain when following scenario 1 of this thread exactly.

4.	I have the battery drain across multiple Roms. Since my first round of testing on Cromi-X I have since upgraded to CM 11 and am still seeing the issue.

a.	I did a fresh install of the latest nightly of CM11 two nights ago including a full wipe of internal storage. I did not install any google apps, the only things installed were those included with CM11. I went through the initial setup, turning everything off (location services CM account, etc.), turned on airplane mode and then switched off the table. Woke up the next day and had lost 70% of the battery.

b.	Once I verified that I still had the drain after a brand new full install of CM11 I installed a few battery tracking programs in order to try and locate the source of the issue. It appears that the tablet is being kept awake nearly 100% of the time by a kernel wakelock. I have included screenshots below from better battery stats, GSAM battery monitor, and Wakelock Detector. All three show similar behavior.

5.	I have the drain problem across multiple kernels. On CM11 I have tried stock, Grimlock, and Geass kernels, each with identical behavior. On Cromi I tried stock, _That v4 and _That v6 with the same results.

6.	Randomly (1 out of 5 to 10 times) the drain does not seem to occur during standby. I have not figured out any correlation at this point as to why.

7.	When undocked, my tablet drains about 6% every 24 hours. When docked the battery drains about 5% per hour.

8.	The battery drain starts immediately when docked (with one caveat, discussed below). It does not have to wait until the tablet hits 70% and begins “charging” the tablet.

9.	I have tried greenifying every allowable app before I did a fresh install, including the allowed system apps. This made no difference.

10.	I have tried using elixr to stop some google play related services as was recommended in one thread, this made no difference.

11.	I have tried placing the tablet in airplane mode before putting in standby, makes no difference.

12.	I tried removing the SD card from the dock, makes no difference.

13.	I tried turning off the dock input in the Language/Input settings, made no difference.

The wake locks indicated above do not seem to start until the tablet battery percentage drops 1%. For example, if I put it in standby at 100% and turn it back on 5 minutes later and the tablet is still showing 100%, I do not see any abnormal kernel wakelocks. However if I was 30 minutes and turn it back on and the tablet shows 99%, then I see the wakelocks as indicated above. Hopefully this makes sense. This is sort of anecdotal information that I have not fully confirmed yet.

I have not tried going back to stock ROM yet to see if the problem persists there, nor have I tried downgrading the bootloader and going back to a previous stock or Cromi rom to see if the problem is still there. To be honest I am not sure it is possible to do that, I have to do some research.

Again, I know this does not match everyone else’s experiences with this issue, as most people seem to believe it is tied to a specific app. That does not appear to be the case with mine. Sorry for the longwinded post, just trying to help shed some sort of light on the issue. I would really like to have my dock usable as something other than a paperweight! Thanks!
