sory2 jz edited my post, by fm radio i'm referring to the default stock app. Only 3rd party one can be used.

Damn, this is exactly what i did after work  .
What the original battery price?
And any recommend 3rd party battery to replace it? (like sun global)
Thanks.

hello

have use galaxy w for 1 year++. now got problem

the battery drain like drink ice tea. everyday have to charge. before this, it can stand 2 day half.
my usage daily are basic. most of time make calls 2 or 3 times and sms-ing 4 to 5 times a day. seldom on wifi. when on wifi, just check fb and whatsapp for 10 minute then turn off. very seldom use packet data. only used when really really needed. very very seldom use heavy apps like papago. the rest of apps also seldom used like games, note, calendar etc. my galaxy w is super basic from start use until now. no rooted at all

i've try update os if new update can solved it but it says up-to-date. how do i solved this problem?
