It's time to replace my N9 Battery, the battery drains in less than 30 minutes when used and 4 in hours when idle.

The question is what battery is the best? Can I use batteries that are used in some of the Windows Phones (The cases are similiar in some of the phones so is it possible?)


I'm good at tweaking my phone so if it comes to that I'd like to atleast give it a try ( I've added the wireless recharger to my N9 inspired by some guy who did it 1st @ youtube )
