Apple today rolled out a key update to iOS 9.3.

Version 9.3.2 solves one niggling problem with iOS 9’s Low Power Mode for extending the lasting power of the last 20 percent of an iOS device.

Today’s update also fixes a bug that caused audio quality issues for some devices that connect to the iPhone SE via Bluetooth.
