Hope i am not alone with this problem. I'm using a Lumia 720 since its release. It was working great, no problem with the battery as well. At least it use to work for 8 to 10 hours once charged 100% with average uses like browsing, songs, chatting, etc. As Nokia has releases the new Amber update for number of Lumia devices, i received the notification for my 720 yesterday. As keeping the devices updated is good, i just updated mine also to Amber.
Update process went fine without any problem, however it took over 30 minutes to complete the process. I also got some new features but here is the problem. My battery is now getting drained in less than 4 hours of time with even less usage compared to earlier. Damn, whats wrong? Since yesterday i had to plug in the charger 5 times in last 24 hours.
This is surely a crucial problem. Is it just me or somebody else noticed the problem. How can i fix it? Is there any way to roll back to earlier firmware? Please help soon.
