Hello everyone, I've already posted this in another thread before, but I keep seeing people having troubles with their drain software wise and figured this information deserves its own thread.

To everyone who thinks their B60 or above dock might be defective (getting drain even with the mobiledock battery saving mode checked on), please read this post. I had originally thought my previous B60 dock was defective because I was getting drain. I never thought there was some rogue app that was killing my battery, because after exchanging it, my new dock was great. This was probably due to myself removing another rogue app, unknowingly. Then my new dock started experiencing some SERIOUS drain (40% overnight when originally below 5%). This post is going to outline how I went through troubleshooting my battery drain. Please don't just resort to the mentality of blaming ASUS for everything and try to troubleshoot your battery drain problems using this post.

After troubleshooting my drain extensively (my dock was great - about 1% an hour, until a couple nights ago), I figured out the culprit was fancy widget. Now I get ~.5% drain/hour on the dock because the tablet goes into deep sleep without any disturbance.

At first I tried freezing the mobile apps with titanium - didn't do the trick for me. Tried uninstalling google maps - still no go. Tried setting every widget (including fancy) to manual refresh. Still nothing. Then I figured out that my torrent widget (transdroid) wasn't connecting to my IP because it was configured wrongly. I had hoped that since that was the case, the drain was because it kept trying to connect. Nope. Tried disabling the GPS location setting in News360 - nothing. I've also tried disabling GPS, bluetooth, google search using location, and pretty much everything in this thread as well as other drain threads in this forum. Still had a ton of drain.

Then, after a factory reset, and installation of select apps, I figured out it was fancy widget, which I installed the other day (consequently, the day the draining started). This is to just clarify to you all that even if all the fixes in this thread, or any other thread does not work for you to stop YOUR specific drain - that does not mean that there is not a rogue app killing or battery, there probably is. So it's your job to find it (:

Also, to clarify on the touchpad waking the device - it will ONLY wake the tablet when the tablet is AWAKE. If the tablet is in DEEP SLEEP, then the touchpad WILL NOT wake it up. Originally I had thought that the touchpad waking the device on my previous dock was the problem, and that the dock was defective. This was not the case. In retrospect, this was because my tablet wasn't going into deep sleep. I had a hunch that the touchpad waking the device was related to deep sleep after some time, and verified it using cpu spy. Now, the useful thing about this bit of information is that you can actually use it to your advantage, much like I did. Troubleshoot your own battery drains by configuring your widgets/uninstalling certain apps, then pressing the power button on the TF while leaving it docked. After 5-10 minutes, swipe around the touchpad and if it wakes up, then your tablet is not getting into deep sleep. If it doesn't, then your tablet is. HOWEVER - this is not the end of your troubleshooting here. Even if it doesn't wake up after 5-10 minutes, it does not mean it won't wake up after a more extensive time period, say 8 hours (overnight). So use cpu spy in conjunction to the touchpad waking feature to see whether or not your tablet goes into deep sleep.

Attached are pictures of system apps I have frozen (some not to solve drain) and consequently work in leaving my tablet in undisturbed deep sleep. Note, some of these system apps I froze just because I don't use them. The most notable freezing I did was market updater 1.0. I started getting drain after updating to the late 3.1 update, and started troubleshooting my drain again and why I would not be getting into deep sleep. I found that market updater 1.0 was the cause. Don't worry, this doesn't break updates for your apps - I believe it just constantly checks for an update to the market. You can defrost it when there's an update for the market.

Exchange services probably doesn't have to be frozen - I just never use it. Same goes with Movie Studio, Market Feedback Agent, and the widgets. I'm just showing my current setup which has solved my drain for ME. So use it as a guideline to fixing yours.

Also, to add on the exactly how much my dock is losing in standby - I lose barely anything overnight with wifi set to turn off when screen is off. Maybe 2-3% over an 8 hour period on the dock. When wifi is set to on always, then I lose about .75-1% an hour. This will probably vary for you, but keep in mind that wifi set to off when screen is off is the best option if you want the most battery. I have all location settings unchecked except for "Use wireless networks - Location determined by Wifi". Bluetooth is off.

Sorry for the long post, but I spent 4-5 days infuriating myself over this deep sleep problem. I figured those who read this won't have to go through the pains I did. Good luck on solving the drain guys!

In summary:

Freeze - mobile apps, market updater

Uninstall - Google Maps, Street View

Check Settings>Applications>Development and keep stay awake when charging unchecked

Check location settings - uncheck all but first option (wifi for location)

Also, if you don't use any of these system apps - I suggest freezing them if not just the sake of getting rid of bloatware.

If none of this above works, then you must troubleshoot using the steps I wrote above (possibly factory reset, and select installation to figure out which app is keeping your tablet awake).
