Hello to all, my iphone turns off when I open an application, or when i get a phone call. I can turn it on when the phone still have 70-100% of battery but when the battery is lower the phone just show the apple logo and turns off again. When this happens i have to connect it to my computer and it stars normally, or sometimes after 10 min later and the phone has like 30 or 40 percent. Also when I use my phone with a power source connected the phone never turns off. I hope you can help me. THANKS .
Ernesto, I think you already know what your phone needs ;-) “Also when I use my phone with a power source connected the phone never turns off.” I am pretty certain that a new battery will fix your issues. The iPhones do weird things when the battery goes out…Good Luck iPhone 3GS Battery Replacement iPhone 3GS Battery
