Guys i got 1 samsung galaxy W bought last year which have a great battery life, night time when sleep for around 8 hours, the phone idle use around 3~8% battery only.

Recently bought a new Galaxy W(few weeks ago), stock ROM and no software installed yet, its always 16%~20%++ every night idle. Even Factory Data Reset still same.

So same phone same settings (Off Wifi, Off GPS, Off Bluetooth, Off Backgroud Data) already Off everything, Idle 8 hours the new Galaxy W is double battery consumtion of the old one.

Old Galaxy W can play games and listen music a bit, 3 days+ charge once, if totally Idle might be can last 4~5 days? So far I is 3 days charge once with little use.

New Galaxy W, idle no use also need to charge everyday. Anyone facing this issue with recently bought Galaxy W?

Ya checked both phone, they are both exactly same everything in the "About Phone". Just that the old galaxy W came with 2.3.5 and later took to samsung service center upgraded to 2.3.6. The new galaxy W comes with 2.3.6. But they 2 have everything same in "About Phone".

Apps -> new Galaxy W without any apps install already draining battery. Even tried Factory Data Reset, no user apps except default Samsung Apps, still is same. Draining battery.
