Chosen Solution
My iPhone SE won’t turn on. It did not get wet. Tried the usual tricks (i.e. multiple cables, chargers, held down power and home buttons for long time, verified no debris inside lightning port, etc). I expect something died inside. The phone was dropped plenty of times over the years (but in an otterbox) but no event seemed to come just before the failure. But, shaking the phone I did hear a little rattle. Could be many possible things. Perhaps the power/standby button went bad? Any ideas how to troubleshoot what actually went bad? I’ve disassembled and replaced parts of other phones in the past so I took the phone apart. I don’t see anything obvious. I’d love to at least recover the pictures from this device. Assuming the logic board is still good, could I just put it into another iPhone SE and do that? I could possibly buy a used iPhone SE for not-too-much money. Thanks for any tips!
this is what you need to do.
- Disconnect battery
- plug in charger
- Apple logo will flash on and off if that is the case you have a bad battery. if no apple logo then try this.
- disconnect battery
- get multi meter
- put it on 20 4.put black probe on sim reader metal plate 5.put red probe on 1st gold contact at the top in the batter connector
- voltage will go up and down once the cable is plugged in. if it is not moving and is on 0.1-0.6 it could be a charging ic issue if it is on 0.0 it could be a short to ground easy thing is clean the charging port with abit of isopropyl alcohol and a tooth brush before doing this
The first thing to check is the battery. If you have access to a multimeter, you could measure the voltage directly on the battery flex connector. Anything lower than 3V and the phone will not boot. That could be a bad battery or a defective charging circuit. You could also try a new charge port to see if that helps but anything beyond that is most likely a board level issue. I don’t like the notion that there is a rattle inside. You need to identify what that is to see if it gives you any clues. Otterboxes protect the housing and screen but it doesn’t fully protect the logic board from shearing forces. It’s like falling out of the second floor window with a helmet on and a puffy jacket. You won’t have too many scratches but your internal organs are still going to take a beating :>).
