Seems abnormal.

H+. but how many bar 1/4, or 3/4 or full?

What's your screen brightness level?

Using a few minutes and the battery drops 5-10% is odd, unless your screen brightness is set to 100% and your phone gets weak 3G signal.

I am in JB as well, if you're on maxis, go tweet to them that your area has bad signal reception.

I am on maxis as well and skudai reception should be almost maxed out to be honest.

Well, I unplugged my phone @ 6.30am this morning, and until now; 4.40pm with data on, it's at 84%. Signal H+ is 1/4 in my office, so the signal is flipflopping between Edge and 3G.

Never used my phone much as I'm in office, but used the net for a few minutes during lunch and tea breaks.

Speedmod K2-19
KK5 firmware

No UV, no OC

Also, when you see 3G, that's for the phone to save battery.

H+ is just a faster 3G speed, but the cell tower is the same and the cell band is also the same.

Either UMTS900 or UMTS2100

50-80% screen brightness is TOO high.

Drop it to minimum. No wonder your battery drains so fast.

50% to 80% of brightness is pretty high that's why your battery drains very fast. Drop it to around 30% and you'll save a lot more battery 

I've never played Pokemon game in my whole life. Gameboy, PSP & Smartphones never tried it. I wonder how is it. Do you think there's Pokemon game for Android?
