Why doesn't my phone start after showing apple logo for 0.1 second?

Iphone SE

I tried to change my lightning connector after I had some charging problems. After the replacement, the phone started but when I putted in a charging cable, it did not charge despite the fact the electricity sign appeared on the right corner of my screen.

Thought it was a problem because I did not install it on the right way. After checking everything, tried to start my phone but without succes. While starting my phone, it shows the apple logo for 0.1s and doesn’t show activity afterwards.

Anyone familiar with a problem like this or knows how to help?

When troubleshooting charging issues, I would do the following (in order):

  1. Always try another Lightning cable and charger, preferably Apple original or MFi certified units.
  2. The Lightning cable 8-pin connector should be sitting flush with the housing and completely inserted. If it is not, there could be lint/dust/debris inside the port impeding a proper connection. You can clean it out with fine point tweezers or a dental pick. Just be careful not to damage the pins inside the Lightning Port.
  3. Change the battery. The battery is the weakest link in the entire phone and certainly for charger related issues. It is also the easiest thing to replace. Use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows) to test the battery prior to removal. Anything less than 70% of design capacity will require replacement.
  4. If the battery is in good condition, you can use a USB Ammeter to determine if the phone is really drawing current when it says it's charging. If it isn't drawing current, then I would change the Lightning/Charge Port (which you have already tried).
  5. If a new battery and charge port still don't resolve the issue, then you either have faulty replacement parts (possible) or a logic board issue. There is an IC (commonly referred to as Tristar) responsible for communicating with the charging device and uncertified chargers can damage it. Unplug the battery and connect a known-good (preferably Apple original or MFi) charger to the phone. A properly working phone will show an Apple logo and boot loop. If the Tristar IC is bad then the phone will not do anything.

Yes—the *most likely* case here is that you knocked off the gas gauge filter near the battery connector. The phone is now no longer able to “hear” the battery data, so it doesn’t know to show you the low battery icon and not try to boot. Your battery is dead—but the phone doesn’t know it. It tries to boot but it can’t.


Find a local microsolderer or send it out for mail in logic board repair to replace the filter (and troubleshoot your original problem)
