Step-by-step solutions
Connect a compatible charger and check for a charging indication
Do not override a liquid-detection alert.
Connect a compatible charger in good condition. If the low-battery indicator appears, charge for at least 30 minutes or until it starts.
If no image appears, continue with the restart for your model. Do not open the phone to inspect the battery.
If it does not start, charge before retrying
Do not keep repeating the restart.
If the restart does not turn it on, Apple directs charging for one hour and trying again.
If it still will not start, stop repeating button combinations and request service.
Advanced checks
Continue if the earlier steps did not help. Read each procedure’s precautions first.
Use your model’s button combination
Apply only the matching sequence.
For Face ID or iPhone SE 2nd/3rd generation: quickly press and release volume up, then volume down; hold the side button until the Apple logo appears.
For iPhone 7/7 Plus, hold side and volume down together until the logo. For iPhone 6s or earlier, hold Home and side or top until the logo. For another model, consult its Apple manual procedure before trying.
Still not working?
Tell Apple the model and whether the charging indicator or logo appeared. Understand the effect on your data before authorizing erasure or component replacement.
