@mehrajsalfi, If your phone is rebooting every three minutes then it's almost certainly due to a bad sensor, in this case it's most likely in the battery. Go read the information in @flannelist's excellent Kernel Panic Wiki article and use it to retrieve your panic logs, then come back here and paste the first page or so into an answer so we can confirm the source of your reboots.

It sounds like you've got a bad connection going to your battery, as the battery health coming and going is not normal, and you shouldn't be getting the non-genuine battery warning if you still have the original battery or the battery was replaced by Apple, but we can confirm once we see the panic log.
