iPhone Fixes and Troubleshooting Guides
iPhone problems can involve startup, charging, battery behavior, applications, connectivity, storage, the display, or iOS itself. The correct troubleshooting process depends on the symptom and the point at which the problem occurs.
The iPhone Fix section brings together practical guides for common iPhone problems, including devices that will not turn on, black screens, Apple-logo startup problems, charging issues, network problems, application failures, and system-related errors.
Start with non-destructive checks whenever possible. Check the charging cable and power source when the phone will not power on, use the correct Force Restart procedure for the specific iPhone model, check available software updates, and determine whether a problem affects one application or the entire device.
Different iPhone models use different button combinations for Force Restart and recovery procedures. Avoid assuming that instructions for one model apply to every iPhone.
Be especially careful before using recovery, restore, or erase procedures if important data is not backed up. A factory restore may remove personal information and should not normally be the first response to an ordinary troubleshooting problem.
Use the guides below to identify the iPhone problem that most closely matches your symptoms.
If the device has severe physical damage, liquid exposure, unusual heat, battery swelling, or persistent hardware symptoms, software troubleshooting may not be sufficient.

Quick Answer A falling Maximum Capacity percentage usually reflects normal chemical aging, accumulated charge cycles, heat exposure, or charging conditions.
