Similar to many laptops,[32] iOS 13 has a feature to limit the battery charging percentage to 80%. This feature allows leaving the mobile phone charging overnight without needing a timeclocked power outlet for preserving battery lifespan. Keeping the battery percentage more centered instead of complete charges and discharges reduces strain onto the battery. This reduces the battery aging of the lithium-ion battery and extends its lifespan, which is a severe issue of mobile phones with non-replaceable batteries.
