iPhone 4 died and won't turn on

My iphone 4 just shut off and doesn't want to power on again.

I tried holding gown power and home button but no avail even disconnecting the battery for a while didn't help.

I measured the battery with a multimeter and i'm getting 4.1V on the battery is this enough or too much?

thanks!

I've found the solution to the problem myself.

I just disconnected the power button and the phone powered on when i plugged it in.

So i just have to replace the power button flex and the phone will work again!

这个答案有帮助吗?
