i have iphone 6s that turns on and off all the time i took it to a mechanic he said that its cpu fitting is loose thats why its turning on and off
Hmm…I highly doubt that the problem is that the “CPU is loose”. The first thing to check with the iPhone 6S is to see if your device is identified for the Unexpected Shutdown Recall. Go to this website to see if your phone is affected. If not, then your battery may be at the end of its life. To be certain, use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows). It will tell you what the health of the battery is. Anything less than 60-70% of design capacity will require replacement. If the battery needs replacement, you can find the repair guide here.
