In this guide, we will make you aware of various methods to fix the issue of the 80% Charging Limit not working on your iPhone 15/Plus/Pro/Max. For ages, the iPhone has had an Optimized Charging feature, which, when enabled, will delay the charging past 80% in certain situations. This is done to prolong the battery life span by reducing the time your iPhone spends fully charged.
Now, beginning with the iPhone 15 series, you have a new feature called 80% Limit. As is evident by its name, it will stop charging as soon as the battery level reaches 80%. When the battery trickles down, then the device will again start charging till it reaches the 80% mark and then the charging will stop.
However, some users have voiced their concern that this 80% Charging Limit feature is not working on their iPhone 15/Plus/Pro/Max devices. According to them, the device tends to reach the 100% mark once in a while even when this feature is enabled. So why is this happening? Let’s find out.
