My habit ; it is always being charge in the car. It is always being charged when at my desk. So I never need to worry about battery dying out . Anyway I always have 2 spare batteries ( for emergency ) but for this phone, haven't buy yet. Temporary I have a microUSB 1900maH external plugin battery pack which I posted several pages back ( or checkup page one under Accessories)

Just go to recovery mode ( press Vol UP-Centre button-Power simultaneously ) - select clear cache partition

The rom upgrade will NOT delete/clear any of the data

Will it damage the battery if you charge your phone like this? 

My first cook rom flash : AngeloM XWKE7 1.4

Remember to wipe cacahe partition before flash ( Just go to recovery mode to do it )

Few hours already on it, didn't see any issues/bugs yet. Phone's performance seems slicker/smoother. The XDA site still points to ver 1.2 but if you go to the alternative download link, you can select 1.4

These are the quadrant scores: 3851, 3905

NO . I have doing these for the past several years . All modern batteries has chip that detect full charge and auto cutoff. Exception are those cheap generic batteries which cost RM 20 and below , which most probably do not have such chip builtin. This is why when I buy spare batteries I buy the better types - Momax, Mugen ( these cost average RM 90 to RM 120 each )  and  not those US$3-US$5 type, which even now plenty you can find on EBay for this SGS II

Ok..but why don't you get back original Samsung battery? or HTC battery for HTC phone? 

So you prefer high quality branded third party battery? erm..I think I wont going to get extra battery but I will definitely get car charger for SGS II..what car charger you using now?

I have 2 car chargers - a 1000mA McKal ( used it for many of my phones ) and a iPAD/iphone 2100 mAh USB charger . I used these two randomly. These chargers i bought in Spore cost me about S$60+ . Stay away from cheap generic chargers that usually cost RM 10-30 - I never trust these cheap stuffs.  Always believe don't be penny wise and pound foolish - I am sure you don't want to fry your RM 2K phone using cheap unreliable suspect quality stuffs
The SGS II needs a minimum 500mAH input to charge it

I will never get those cheap things..do Samsung have in car charger? 

did u guys have some sort of animation when putting ur screen to blank using angelo1.4? some sort like tv when black out animation.. dunoo how to explain..
n did u guys remove the app just like the xda people recommend? manage to score 4458 in quadrant..yeh..

It's called CRT screen off ...... Quite common for custom roms to have it these days especially those from SGS .

can we remove it? its annoying to me, like ur device have problem... 

LOL..... i only know how to install it , dunno how to remove it as it's integrated into your system.apk or framework.apk
