Sure. Here is how I get 48 hours of battery. I don't use magic, i just don't care for alot of the things available.


- Inactivated all IM account exept skype which I only put online when I need it. So not for all day chatting.
- No widgets of any kind populates my desktop and no battery/cpu checker in quicklaunch status bar applet.
- No system sounds, no keyboard sounds, no screen vibration.
- No background apps running, downloading or checking anything. No call monitoring, data counters, LED customization and such things
- In application manager I inactivated all catalogs except nokia system software since it checks automatically. I use faster appication manager for all other install/remove/update.
- No leaving things running in multi task manager. Like leaving browser open when im not going to use it.
- Unistalled all apps/games I don't use or seldom use. Like hermes for instance. I keep my app folder pretty clean
- No gaming or video watching
- Only 3 screen desktop
- Use default theme but replaced background images
- wifi power set to 10 instead of 100. Connected with wifi 24/7
- Wifi check every hour.
- Always on 2G network instead of dual/3G unless needed.
- Use autodisconnect for bluetooth (20 min) & Gprs/3g switcher (5 min)
- Check email every 30 min.
- Never ever reboot unless you want to loose a big chunk of battery.
- Screen brightness 3/5
- Don't trust the battery meter. Mine said 0.4% left and was all red. Still lasted idle for 3 more hours.
- Dont charge over night. Charge it so that you can remove the charger at the precise time its done. Otherwise I get 93% battery instead of 98%. I do this while working.


Usage during 48 hours
- 60 min on the phone
- 10 sms
- 2 hours (at least) webbrowsing. Half using opera and half using microB
- 30 min musicplayer
- Writing/responding to email
- 1 hour drawing in mypaint
- 20 minutes using metronome for guitar playing
- 4 pictures with camera and flash
- Some filetransfers with tinysmb or bluetooth
- Silent profile with vibration
- Silent profile without vibration during the night


I don't feel I am compromising in my usage. Would I like to have all that junk running all the time? Not really.
