Ok so here are the impresions.
- Battery life is ok, if you turn off internet during night and use 2G, and 3G only when you need fast internet, 2 days can be achieved P.S. Truth to be told I think my battery needs to be replaced
- There is only one force close, and that is for Baidu File Manager, remove it and replace it with something you use. In my case that's Huawei ICS manager.
- Slow is generally ok regarding responsiveness. Before you unlock your screen wait 1s, and phone will have time to load so it won't stutter.
- I am using only Whats Up and Viber so I usually have around 80-100mb free RAM.
I am going to use V6 script to see how it reacts, and phone definitely needs small overclock to work better.
