I need help. My Iphone 6Plus wont charge while its on the charger. I cleared background running apps before it died. Everytime it gets to the apple screen it dies again sometimes it manage to get enough power to the lock screen and I was able to cut the wifi connection off but I wasn't able to put it on low battery mode, I even cut on air plane mode to help it charge faster, but it keeps shutting off and shutting on up until the apple pops up. it wont go any further than the lock screen and within seconds its dead again. Please help me. I really need my phone.
