Galaxy Note 9: How can I optimise and extend the battery life

Last Update Date : Aug 14. 2018

Galaxy Note9 provides various ways to increase battery usage time and you may feel battery usage time may be short during the initial period (about 3 days) after the purchase(opening) because App power monitor feature and Optimization of battery usage feature do not work properly.      

 

Depending on your usage pattern, if you optimize the battery usage time by activating App power monitor feature and Optimization of battery usage feature, you can use similarly like usage time of the device you had used before from about 7 days after opening of device.       

 

Note: Usage time may vary depending on your device settings and usage pattern, operating conditions. 

 

To increase battery usage time, please follow next tips:

1- Quick OptimizationClick to Expand

On the Settings screen, tap Device maintenance > OPTIMISE NOW.

 

The quick optimization feature improves device performance through the following actions:

 

 • Clearing some memory.

 • Deleting unnecessary files and closing apps running in the background.

 • Managing abnormal battery usage.
