Any tips that you guys can give to optimize C6-01 battery usage?
BTW, usually for you guys, how long will it takes before the battery is fully drain out?
It depends on your usage. If you're perfoming web-surfing or GPS, the battery will drain out very quickly.
A few tips to improve perhaps a little is
1) Change your network mode to 2G Only if you're not using your network data.
2) Reduce the brightness of the screen or you may turn power-saving mode on.
3) Shut any unused apps because multitasking in Symbian will still require processes if it's running because it's true multitasking not "fake" multitasking in iOS

Pretty much nothing else can increase the Battery Time.
The battery capacity is the main thing. While doing the above few might increase your battery usage time, this is only because you have changed your usage pattern.
My personal suggestion : Get a Portable Charger to couple with your phone. Remember to get one with a higher capacity

After using it for one day aggresively, noted 1 prob:
1) auto re-start the phone sometimes; especially after i screen lock it and 1 2 unlock, hang a while then re-start
2) The fixed focus photo really bad!
3) I cant set my sms tone, setting>profiles>general>personalise>Message alert tone>songs>all songs>opening> then cant load and go bec to the initial page
Any1 can help?
Do try reinstalling your firmware as in the whole thing through Nokia Ovi Suite or the older PC Suite.
Anyway, I don't think it's fair if Nokia isn't replacing your phone when there's an issue to it and if you have just purchase it within 2 weeks time.
Try asking NCC again & if they refuse to do a replacement, do check out this site :
National Consumer Complaints Centre and lodge a report against them
