[Q] Horrible Battery life on Droid Razr Xt912

Hello,
I got a used Droid Razr Xt912 (Verizon version) 4 days ago. Android 4.1.2 was pre-installed on it with lots of Verizon Bloatware. So to get rid of it I decided to root it right away. As I am new to rooting I read few tutorials and downloaded Droid Razr Utility. I flashed Offiicial JB firmware and wiped all the Data. It completed successfully. Then I tried to root the phone by using Razr Blade 4.1 Root Exploit by djrbliss.

After completing these steps , I restarted the phone . But when I checked with Root Checker I found out that phone was not rooted successfully. And SuperUser app is not there.

Anyhow the phone is working properly but I am getting horrible battery life. On full charge with wifi, data, and GPS off and lowest brightness the battery drains in 8-10 hours. With moderate use battery isn't even lasting 4 hours.

I never had a chance to test the battery life prior to flashing. So I am not really sure what is happening.

Here is what I am getting in my phone about menu:

98.72.16 XT912 Verizon.en.Us
Android version 4.1.2

Any help on what could be cause of it and how to solve this issue will be greatly appreciated.

I have installed mokee KK 4.4.4 rom. So far battery life is far better than previous stock rom.


There has been a significant improvment
