Battery drain problem solved by me

Hi Guys,

After bought of great ME176CX I faced these battery drain problems also. After long time of investigation and googling I tried to (successfully) root it via RootZenFone-1.4.6.4r.apk, there's a lot of manuals how to do it (start root & after 10 seconds force reboot - done). It's good to verify rooted device for example via RootChecker by joekrim.com. Root proccess is here at ME176CX very lighweight with no problems, no personal data deletion, no app settings deletion and so on. So there's no need to be adfraid of rooting with RootZenFone.

Now I installed Link2SD (great job by Bulent Akpinar) and wipe off all Asus & Google bloatware (with some googling). For the first time I only froze the apps. They recommend first freeze it and when it causes no problems to your Android you can later uninstall if you want or need some additional space. List of apps is below - it's about 90 apps (!) and I think could be more when you take additional time with googling. Maybe I'll do later.

I rebooted (just to verify it won't get stuck somewhere) and have now great tablet with excellent battery life. I installed Wakelock Detector by UzumApps - with rooted device you can run it without problems. Now it shows my tablet is awake from 1 to 3 % when you take it in your hand from time to time per day. When I faced the battery drain problem I commonly had about 90 % wake time (via Wakelock Detector "unblocked" via ADB).

Unfortunately I did not discover where's a problem with battery drain with this model. But in Wakelock Detector I often saw BTLowPower process which caused tablet could not fall into deep sleep (cca 90 % awake). So I think Bluetooth could do this - that's why I froze Bluetooth.apk also, see below.

When you don't know anything about ADB & running Wakelock Detector - in Android was my problem visible only in Battery panel where was "OS Android" on the first places of battery consumers and after showing it's details it showed in column "Disable to fall into deep sleep" (don't know the exact translation to English) for example cca 9,5 hrs from 10 hrs tablet uptime. Now I don't see column Disable... in "OS Android" details in Battery details.
