Every Nseries users and all mobile phone users will have the same problem. The battery dried up pretty fast. My N73ME only can last long for about one to one and half days only. This is because I always use the video call before I go to bed. But if you are a normal user, you can save and extend your Nseries battery life more longer.
1. Turn off bluetooth – How many of you turn on the bluetooth all the time? Bluetooth uses power to run. If you are not using the bluetooth, it is better to turn it off to save the battery.
2. No Games – Although our Nseries phone is a smartphone but I think it is not necessary to use it for playing games. Unless if you are a hardcore gamer that love playing mobile games from your mobile phone.
3. Low the Brightness – I set my display brightness to medium. Don’t set your brightness display to high because it will consume more power usage. And don’t set it to low or you will threaten your eyes.
