But your phone isn’t always great at measuring that-if your battery has degraded to 95% of its original capacity, your phone might still report that as 95% full, instead of 100% full (the “new normal”). Only if these variables require it, iOS will dynamically manage the maximum performance of some system components, such as the CPU and GPU, in order to prevent unexpected shutdowns. However, two to three times a year is fine but if you continue to face the incorrect. This performance management works by looking at a combination of the device temperature, battery state of charge, and battery impedance. Batteries naturally degrade over time, and their capacity slowly decreases. Unless there is a genuine need, you need not calibrate your phone battery.

While it’s really not that big of a problem, it can be a bit annoying when your phone says you have 25% battery left, only to look again and see that it’s nearly dying. Here's how to do it: iPhone 8 and later: Click and release the volume up button followed by the volume down button, then press and hold down the power button until the Apple logo appears on the. This is a problem that occurs in most battery-powered electronics these days, so this process should work on iPhone, Android, and even tablets or laptops (almost all of which use lithium ion batteries).
