Need to install adobe reader.

Do you have Polaris Office in your phone installed? It's the app come with the phone..pretty good app..
Use Odin to flash then 

are u on custom rom? if not, this is one of the reason why we revert to custom rom. the developer had tweaked their rom for better battery life.

using the juice defender or any battery saving apps may or may not improve your battery life performance.

its not that complicated at all. to improve battery life, you need to understand this 2 things; 1) standby time and 2) screen on time.

1)standby time

this is one of the thing that we forgot that the less we use the phone, the more standby time it will get.. so it will be useless if our battery can last 10 days but we barely use it. and with custom rom, the developer had tweaked some of the voltage properties so that when the screen is off, the system uses a minimum voltage, thus save battery.
if you want long standby time, switch off 3g connection, use wifi instead of data connection if possible and even switch to flight mode if you one. but this will make your SGS2 lot less than a smart phone right?

you also can buy the Samsung 2000mAH extended battery kit for extra 1 day of standby time like me.

2) screen on time

for me, if we can use or utilize the phone as long as we want, that is the best battery life. that means if you can use your phone for about 6 hours screen on time in one day, that is a great battery life.

the longer the screen on time, the more you use your phone.

so make your pick.

based on my experience, checkrom revolution HD 2.0 + siyah kernel 2.2 beta 6 is the rom with the best standby time and screen on time. check my previous post regarding my battery life report with screen shots too.

buy the good one..
i dont use any..
eventho i get 1 free, because i bought SGP Neo Hybrid, it comes with a free Steinheil™ Screen Protector Ultra Crystal Film

this one supposed to be very2 good..
but not yet applied~

dont worry, we use Gorilla Glass for the screen mah.. very strong, but dont how how scratch-proof it is~ 

Are you using G version?

hmm.. i recommend u to use papago x5
as i know it is faster thn papago m7

Didn't i replied you??

It means the kernel was successfully flash. Can you boot into your phone now?
