Hi all 
I want to try new looks & themes, so I am gonna install either DB or WB. I am on 4.3.3 jailbroken
1. Just installing either of those (& not applying any theme) can make my phone slower or decrease battery ?
2. After applying theme, any decrease on speed or battery ?
3. Can it be completely removed if I am not happy ? After removing hoping that my battery & speed will be back like earlier ?
4. which is good ? DB or WB and why.
And anything I should know.
I read somewhere that it will make phone very slow and even after uninstalling it's side effects will be there.
Thanks in advance
