You can turn off the optimized battery charging in iOS 13 to fully charge faster
Apple has improved battery-related options. In order to solve the problem caused by the long-term use of the battery, Apple has also added an optimization strategy, which can improve battery charging and extend battery life. But the corresponding is that the battery charging speed will decrease after this optimization strategy is turned on, the battery charging optimization option is enabled by default in the iOS 13.x series.
If you travel frequently, the iPhone may need to be fully charged as much as possible, avoiding the need to find a place to charge when the mobile phone runs out of power on the road. Under normal circumstances, it takes a certain time to fully charge the iPhone, so if the battery is not fully charged near the departure, you can turn off the optimization option. For example, most domestic airport lounges have power sockets. You can connect the socket to charge during the waiting period before boarding. At this time, you may need to speed up charging.
By default, the system will optimize charging after charging the battery to 80%. The remaining 20% of the lighting may take a long time to fully charge. We can go to the settings of iOS 13 version, Settings > Battery > Battery Health and turn off Optimized Battery Charging. After turning off, the battery can be fully charged faster.
