The Nokia N8 and the Nokia E7 are among the most popular smartphones nowadays, and I guess their popularity will grow even more after they get huge discounts.
Both smartphones have a number of useful features, functions and cool apps, and sometimes we can spend the whole day playing with them. The only problem is that all those applications and features drain the battery quickly. So does the work in the 3G network. Plus if you use the famous 12MP camera of the Nokia N8 or shoot 720p HD videos with your E7, your battery will be “dead” very soon.
What should you do then? Well, first of all, as some people would say, if you don’t use your smartphone at all, its battery will last for a really long time! 
But if it’s not what you really want, Steve from All About Symbian has found something you’ll find very useful. He wrote a little tutorial about the way to improve the battery life of your N8 and E7.
His tips include WLAN power saving (enable the WLAN “Power saving”), choosing carefully between 3G and GSM (use more GSM, especially if the 3G coverage is bad in the area), choosing the right color for the OLED screen (black is better than white), not forgetting to shut down the unnecessary apps and many others.
Steve’s tips seem to be very useful, so if you’re an owner of a Nokia N8 or a Nokia E7, perhaps you should read them and take them into consideration, if you really want to double the battery life of your smartphone.
