Save your Nokia battery life

Do you guys know that there is a trick which may seem quite simple but is an effective way of saving your battery life.

First of all you have to lock your keypad and then you can click the left soft key or the red button(anyone or both may work). Doing so will immediately switch off the backlight of your cell phone.
Although this may seem so simple, it saves about 10% of your battery every time and this decreases the no. of times that you will have to recharge your batteries thereby increasing your battery life…

This works in all smaller handsets upto 6233.
