How to Charge an iPhone Past 80 Percent When You Need To
An iPhone with an 80% Charge Limit can be charged to 100% temporarily through Settings. Open Settings > Battery > Charging, select 100%, then connect the charger. On supported iPhone models, the charging screen may also offer Charge to 100% or Allow Until Tomorrow as a temporary override.
Steps
- Open Settings and select Battery.
- Tap Charging on iPhone 15 models and newer.
- Move the Charge Limit from 80% to 100%, or select Charge to 100% when the temporary option appears.
- Connect the iPhone to a wired or wireless charger and allow charging to continue.
- Return to Settings > Battery > Charging and restore the 80% limit after reaching the required charge level.
🤔Note:
On some iOS versions, the temporary option appears by tapping the charging limit notification on the Lock Screen or in Settings > Battery. Menu names can vary by iOS version and iPhone model.
💡Protip:
After reaching the required charge level, restore the 80% Charge Limit to continue reducing battery aging.
Common Issues and Fixes
- iPhone not charging past 80: An active Charge Limit is the likely cause. Set the limit to 100% or choose Charge to 100%.
- The Charging option is missing: The iPhone may be older than the iPhone 15 series, or the device may need an iOS update. Check Settings > General > Software Update.
- Charging stops near 80% with no limit enabled: Optimized Battery Charging may be delaying the final charge based on charging routines. Open Settings > Battery > Battery Health & Charging and review the setting.
- Charging pauses above 80% in high temperatures: Thermal protection can temporarily limit charging. Move the iPhone to a cooler location and remove a thick case during charging.
- The battery percentage remains unchanged: A damaged cable, weak adapter, dirty port, or incompatible wireless charger can interrupt charging. Test a certified cable and power adapter.
Quick Tips
- A Charge Limit of 80% helps reduce battery aging but can be changed whenever a full battery is needed.
- Charging to 100% once does not disable the feature permanently when a temporary override is used.
- After changing the limit, allow several minutes for the charging status to update.
- Wireless charging may generate more heat, especially inside a vehicle or under a thick case.

How can an iPhone charge to 100 percent once?
Set Settings > Battery > Charging to 100%, or select Charge to 100% from the temporary charging option. Restore the preferred limit after the battery reaches full charge.
Does Optimized Battery Charging override an 80% limit?
No. A Charge Limit takes priority. Optimized Battery Charging mainly delays charging beyond 80% when no lower Charge Limit is active.
