So, what do you do when you feel like your T-Mobile Samsung Galaxy Note 2 SGH-T889 could perform better and faster? Well, you flash a ROM for starters. However, if you like your current ROM and don’t want to change too much of what you have, then you flash a kernel.

    One of the better known kernels in the forums of XDA is the Perseus kernel. This mod was first introduced in the Galaxy S3 forums and now it has been ported to the Galaxy Note 2. XDA Developers member AndreiLux has created a Note 2 version of the kernel for the international, international LTE, and T-Mobile builds. This kernel packs a punch and allows you to overclock your CPU to 1.8 gigahertz and undervolt it from 600 to 1,400 megavolts. In addition, the USB charging rate limit has been increased to 900 milliampere-hour. This kernel promises a faster and battery efficient experience on your Galaxy Note 2.
