I flashed to 14.04 and after using it, I am not seeing any battery improvement. People are saying good things about battery life but I think something is weird here.
As I said before since aokp build 30 the battery draining is very fast when using phone. I wanted to show you this before but I will do it now using the last update.
As you can see I started using ROM after I backed up everything and flashed to the last update. At that time battery was around %87.
After using the phone a little and playing around with settings and apps, The battery started draining very fast. As you can see in the picture it dropped %70 in such a short time.
Again, I left the phone and tried working with it, In the second time, It was draining battery blazing fast in just a short time.
I just made a imaginary blue line so you can just think how it could go if I continue working with phone.
When The phone is on standby, the battery drain line is very straight like it never is going to finish. But after waking up and starting using it, the line goes down as fast as it can.. !
