Chosen Solution
Hie my name is Chuck and am from South africa,i have a iphone 4s which has battery connectors issue,after damaging when i was replacing the screen,the iphone powers on perfectly but the problem is that after a while 5-10mins of using it,it reboots on its on and works again then again reboots,but when u leave it eg on top of a table it doesnt not even reboot coz i did that when i went to work and left the stop watch on juss to see how long it would be on,when i came back it had been on for 6hrs,without rebooting. And when i put it on charger it shows that its charging but the battery percentage doesnt go up its keeps still on 13%..but when u leave it on the charge for 30mins or so and reboot it,the battery percentage would have gone up to maybe 35%..i cant see the battery percentage recharging or discharging..what could be the problem? Hope you guys can help
you probably lightly crack the solder of the battery connector maybe just pass the soldering iron whit flux could replace the solder
