First things first....atk is a must!

[dakidobf]

The battery life debate will always go on. Some ppl say use the ATK, some say it does more harm then good. Not two people really use their phone the same, so there is really no 1 thing that will work for everyone. Instead of saying, you MUST install this, maybe say this is what you did and how it worked for you. Tell us how you use your device so we can then make our own conclusion.

But the best thing to do is run your own tests and see what gives you the best results.
