Iphone 4S won't turn on - 1

Sometimes my iphone 4S will randomly jump its battery percentage to 1% and to fix the problem temporarily, i would turn it off and then turn it on. But ytd, it jumps to 1% and when I turn it off, it won't turn on anymore even when i hold on to the power button. I tried charging it and I left it on until this morning it turned on by itself but the battery percentage is still 1%. I tried turning it off to fix the percentage but now, it won't turn on anymore.

Go to Apple Store

If your Iphone still has warranty then take it back to where you got it from.
They will either fix it or will give you a new one.
