Unfortunately symbian phones are spending too much battery. I have a Nokia 6060 and It’s working 4-5 days without charging. It’s really hard to say the same thing for S60 devices. But we can increase our battery life with a few tips
1. Close applicatons that you’re not using – If you press to Menu button 
for 1 seconds you can see applications currently running.
Running applications means loosing more battery. If you don’t use them press to C button and close them. You will notice the difference
2. Turn off Bluetooth connection if you’re not using
3. Don’t use any additional Screen Saver. Use Nokia’s Default Power Saver
4. Set your Power saver time-out to “1 minute”
5. If you’re getting Low Signal, don’t talk with your phone. Because in Low signal, your phone is spending more energy to reach to the base station
6. Use Original Nokia batteries… Fake chinese batteries can be explosive!
If you know other tips, you can share them with us
Thanks for info…
If you need maximum battery life you should enforce terminal to use only GSM network, not UMTS at all. Default setting is that phone tries to use UMTS when available, making terminal to switch between the two modes constantly.
In settings got to “Networking” and switch Network option to “GSM” or “Dual” as per your need.
Reduce brightness.
One more trick.
You can put your phone into offline mode or even better turn it off for a night.
Don’t turn-off the phone at night.
Thats a mistake .
The phone consumes more power, when you switch-it off and at the boot-time.
Do it 4-5 times in a row even with a full battery and see what happens.
I can acknowledge saving battery when you never powercycle your phone. Leave it on !
I think I also have some additional tips to save power:
1. just closing apps is not enough, also really quit ALL programs & processes on the phone. You can do that with e.g. “Best Taskman”. Some programs actualy don’t quit if you just “quit”, like e.g. the menu. You have to select exit (strange).
2. put/install your small apps that you really want (e.g. a theme, keylock)in the phone memory instead of memory card.

Before above measures my phone (E70) lasted less than 2 days, after that it lasts over 5 days (!)
Dim your backlight
Even though it doesnt look as bright,save A LOT of energy
Don’t use dual-mode or umts unless u really need it, turn to gsm-only.
Go to Settings -> Connection -> Packet data and set the packet data connection when needed, not automatically. This way the phone wont be constantly checking if packet data is available, rather than opening it only when really needed.
Dont ever set the “Show WLAN availability” to enabled, serious battery sucker and without no benefit!
If you want fast internet-access, turn your phone to UMTS only. no annoying 2g-handovers.
Thanks for the tips admin, also thanks to, Harri, Gamias GR, tsmeallright and Ville Turpeinen
What’s your opinion about that “Offline” profile? My Nokia E51 has it. It actually disconnects the mobile from the GSM network does it? I believe it is a powersaver and it is better to use this instead turning off the mobile at night, what do you think?
Hi!!
Try to make always full charging cycles to your battery. Try not to let it turn off, recharge when it is asking for it
Decrease display’s backlight..Worked on my 5700 XpressMusic!
Quitting applications may or may not do much (unless these applications are actually doing work, maintaining a network connection, etc).
For instance, quitting VoIP software like Fring might be useful, but quitting the Nokia Geotagger would not be (it does not maintain GPS fix or other connections while sitting idle in the background).
Some better tips:
* Turn off keypad tones (Settings -> General -> Personalization -> Tones -> Keypad Tones); otherwise every time you push a key, a beep is emitted.
* Turn off automatic WLAN scanning (Settings -> Connection -> Wireless LAN -> Show WLAN availability: Never). It will still perform scans every time you return to the idle screen, or when you select the last line of your idle screen display.
* Turn WLAN trasmit level to the lowest setting, 4mW (Settings -> Connection -> Wireless LAN -> Options -> Advanced Settings -> Continue Anyway?: Yes -> Automatic Configuration: Disabled -> TX power level: 4mW). A lot of people choose higher settings believing that this will give a better WLAN connection; in reality this is not always so. (Devices tend to over-saturate the RF channel, thus actually degrading wireless performance).
* Do not enable automatic checking/retreival of e-mail; close the e-mail client when you are done reading. (Same with other internet applications, as e.g. the web browser might be told by certain web sites to refresh content every so often..)
it is also a trick very important if u reduce the brightness level This is a major power saver
What is the point me having a N82 if I can’t keep running the apps that I want? I might as well send it back and get a nokia 1100 or something.*lol*
thanks dear friend..
for useful tips
one great way is best profiles by i don’t know what software provider
and i set my phone to automatically switch to offline profile during workweeks and not in the weekend. Also you can change to a certain profile when you enter a certain area (this is done by identifying network cell which serves that area)
Energy profiler
N95 and Watt consumption:
LIGHT
0.35W with light enabled
0.15 - 0.20 W when light disabled, but displays shows normal information
0.03W (!) when light disabled and default nokia screen-saver enabled (dark display with datum and clocks only)
Display light (in dark place/outside on sun)
very low - 0.2W/0.31W
low - 0.28/0.32
medium - 0.31/0.35
high - 0.42/0.49
very high - 0.45/0.65W
BLUETOOTH enabled but no transfer of data 0.35 - 0.36W (meaning disabled bluetooth will not help you)
WIFI enabled
when data transfer up to 2W
when not transfering data 0.40W (0.35W without wifi enabled, so wifi without data transfer consumes 0.05W)
CALLING up to 1.8 - 2.2W
ACCELEROMETERS disabled saves around 0.02W
If in off-line mode (the GSM is shut down) it consumes approx the same as if in normal mode. You can save only about 0.02W in good signal area.
EDGE - 1.5W while data transfer
2D game, 2D with acclerometers and 3D games surprisingly consumed same amount of energy - 1W when playing, and 0.05 more Watt (total 0.4, while normal is 0.35W) when running, but not directly in game.
Apps running sms/contacts/profiles/settings/apps folder opened make difference of 0.01W
Conclusion:
Disabled GSM, Bluetooth or acclerometers will not save you much energy.
If you pause game and leave it, or if you open multiple windows in symbian it consumes just a little bit more Watts, its not big deal.
On other hand calling, using wifi or edge consumes a lot. Also you should disable wifi even if you dont transfer data, while you don’t have to disable bluetooth while not transfering. Then the most important for you is to set your brightness to medium possition and enable your default nokia screensaver which save a lot energy when you dont use your phone.
