Next to my HTC One, I got a samsung galaxy S.
The problem with my i9000 is that it's really slow with a lot of freezes and the battery life is also really bad, it lasts for 12 hours with almost no usage. At this moment it's running android 2.3.3.
I want to make it faster and have a longer battery life.
I'm new into these things and don't really know what to do or how to do it, so I would love some help.
Do I need a custom rom or an other kernel?
If I need a custom rom or kernel how do I install those?
I appreciate all help
By the way, sorry for my bad grammar, it's not my native language.
