Android devices have grown in power recently, thanks to custom ROM feature updates and sophisticated software that put the whole world at your fingertips. But the price being paid is often short battery life, and heavy gaming, internet browsing and media consumption are just a few of the things that can drain your phone's battery faster than expected.
Now Galaxy Note 2 users can extend their battery life with the Battery Plus Jelly Bean ROM, thanks to XDA Developers member, Hendrickson. The Battery Plus ROM is built on the XXALJ3 baseband firmware and reportedly offers better battery performance than any other custom ROM firmware. The ROM also features an exquisite UI displayed in 240 dpi, which is impressive on the Note 2.
