yes my sgs oni can last to 8 hrs oni.. i heard from this thread, some of them can last for 2 days?
ive check my task manager 1.51 there is no running apps.. but the RAM used always approx 240 / 399 mb? is that normal?
im vr2 curios rite now.. can last oni 8 hrs without doing anything.. what if i make a call or else..
btw... where can i find the dxjpa modem? did the 2 days guy also use this modem?
really need some sifu advise here...

Few basic things to do is, set lower brightness, normally display is the one took the most battery life
Use 2G instead of 3G, the difference between these two is huge! 2G is enough for you to synce emails, whatsapp and facebook. Only change to 3G if you wan to watch youtube or browser internet that requires faster network speed.
To change to 2G, go settings - > Wireless and Network -> Mobile Networks -> Network Mode -> Choose GSM only
Then go market download spare parts, use it to check battery history, if your phone Running is very high or 100%, must be some apps that preventing your phone to go to sleep.
-----------------------
And remember to calibrate your battery if you just flash a new firmware.
To do this, drain your battery till close to 1%, reboot into recovery, find an option to delete batterystat
Then charge till 100%, leave it at charger for another half an hour, then delete batterystat again.
----------------------------
One more way i found recently.
Go market download Battery Doctor,
When your battery life lower than 20%, open the app, then plug in the charger. Leave the app open all the time during charging
Do this once every few weeks.
