The smart mobile phones are going slim and the batteries are in higher capacity but a shorter using time. Back to 10 years ago, the standby time for Nokia or other phones could stay 2-3 days. That is the standby time for the normal phones of that age. But now things are changed. Mobile phones are smarter but stays less. Wait, let me give you some suggestions to extend your mobile phone battery life without any extra cost.

1. Turn off your mobile phone WIFI and use it as less as you can.Of course, turn off your GPS position of your phone. It will save power for longer standby time.
   
   
2. Try to stay in the places where there is good mobile phone signal. If you get a weak-signal place or place without signal, the smart phone will search the signal very often. The more times the smart phone searches, the less standby time the phone will stay.
   
   
3.  Make your phone screen in a reasonable brightness. The brighter you phone is, the less time it will stay.
   
   
   
4.  Recyle your phone battery every week. Try to make your phone out of power to dead and charge it fully once or twice every week.
