Asus Fonepad Battery Drain in Standby due to Cell Radio(Experts pls Help)
I recently purchased this Tablet cum Phone Device (Asus Fonepad) in India. I found this device very impressive with decent battery backup along with great standby time. Everything was allright. In morning I found heavy battery draing during standby.
Next day I uninstalled that Black market application and Uninstalled Exdialer with all downloaded themes. I got full signals and everything was working fine. But the Battery Drian in standby remain same. I observed the situation till next two days. I serached to forums and did following things:
1. I made factory reset to my fonepad. which was haviing 4.1.2 Android after updating through OTA. Which remains same after Reset.
2. I didnt install any other applation
3. I turned of all battery comsuming services like GPS/ Location reporting/ Data/ Wifi/ Uninstalled Google Play Service Updates etc
4. Installed Wakelock detector, Better Battery Stats etc All are showing that phone goes in deep sleep no prblem but Wakelock detector show that Cell Radio wakes up so much time when phone is on sleep mode. Default Battery monitor of Android Showing "Mobile Data" as most battery comsumer.
One thing I want to mention here the device is supportive to mini sim only. I was not having mini sim so I went to market and mobile shop keeper cutted my Sim to adjust into that slot and it woked. I was using same sim from Day first. It's Vodafone INDIA.
I googled the issue but no luck to find the solution. I have not rooted nor flashed anything from my fonepad.
I am reached to the conclusion that There is some problem with Exdialer installation and applying new/old theme combination to it which made me device with no signal. And now The Cell Radio has been changed which is attempting to achive something in standby mode. Which is causing heavy battery Drain. Standby time is reduced to almost 15-16 Hrous
Experts Please give attension and please help me as I am very helpless this time and hoping a solution to th problem.
Thanks in advance.
