i dload jpo from xda forum. it has built in kernel k8 i think. i didnt remember. then i install k9a. the bat drain so fast. some said jpo not stable for asia. better to use jpa. plzz help me. 20% in hour.
Actually JPO is pretty good if u compared to JPA.
I think one of the sifu kmrdeva also on stock XXJPO with kernel K10H, he seem pretty with his battery.
Let see..:
1) check setting > application > running services --- see any apps that drain battery, like whatsapp, mail...
2) *#*#info#*#* > batt history - other usage: what ur running and screen on percentage ; sensor usage: what the percentage of each of the percentage
3) did u have any widget running? like 3G watchdog (watch refresh interval)
Do check on this 1st, then reply ur finding on the above question, i think other sifu will try to help u to solve the problem.
