GSM-Forum - View Single Post - iPhone 6 High consume on boot then gets normal, during use reboot

Hello guys...

I have 3 iPhones with the same behaviour. On boot, they gets over 1.1A on power supply, after that, the consume stays normal, at 0.2A ~ 0.4A, in stand by gets down to 0.016A to 0.030A.

But even then, after some time of use, the phone randomly reboots itself.
It can turn on normally on power supply due to 2A supply, but on the battery with only 1A maximum supply they keep rebooting itself.

Checked some power rails and no short or damaged cap is found, anyone can clarify what rail maybe the cause?
Thanks!

Ps.: VCC_Main had a cap "bottlecaping" the 4.2v line, changed and the rail is ok now, but the problem persists...
