So recently i just recently switched my old battery with a battery from my old iPhone 4S but after i switch the batteries my phone had so many issues i’ll give you some list to understand my problem below; 1.Device keeps on and off. 2. Device says 100% fully chrged, but when you pull out the charging cable it will shuts down like dead, LOL. 3. Network is searching 4. Keeps on rebooting 5.Wi fi grey out. There you have it i hope somebody could help me on how to fix this,i tried to watch some tutorials on the net but no luck for me, so i hope and pray that in this forum someone could teach me and tell what should i do and how to fix this problems and issues. Thank you and God bless
Sounds like either the battery or the battery connector got damaged. What tool did you use to remove / pry the battery out? Did you make sure to unplug battery before removing the battery physically? Have you inspected the battery cable itself for any signs of tear / physical damage? Also check the battery connector if it’s damaged as well and make sure you have plugged it in fully. 1 and 2 correlate with each other, looks like the phone can’t detect the battery properly. 3. That is normal as unplugging the battery resets date and time to 1/1/1980 which is fixed by either auto synchronizing date/time via Wi-Fi, iTunes or Sim Card Cellular Data. 4. Related to 1 and 2, not detecting battery properly. 5. This is bad news. That generally means the Wi-Fi chip has gone bad and at this point I would consider using the other iPhone 4S that doesn’t have Wi-Fi greyed out.
