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.
