Nokia 2730 runs out of battery quickly

Nokia 2730 consumes power before you check to see if any children give heat, remove or replace, turn on the power to test the function of bluetouth, camera, radio ... see if there is any error function. If the error is caused by that child, you only need to remove or replace it. Check the pressure of the Vcore and Vio bunches from the floor to see if it is normal, if it is normal and remove the others, it is not ok, start over Tavo + Retu first or you can replace the new one. If you try, all of the things above that still don't matter to you, then maybe you need to replace the pair to solve the problem.

The actual Nokia 2730 solution consumes previous power due to memory card ic error, you remove or replace

Good luck!
