How can I optimise and extend the battery life on my Samsung Galaxy smartphone?

Last Update Date : Apr 01. 2018

Display Settings

Display settings: Long screen time-out setting or high display brightness will increase battery drain. 
Try setting your screen timeout to 30 seconds and display brightness to Auto.

Third party apps

Third party apps: Apps that automatically sync data in the background will drain battery - e.g. social networking, instant messaging, news readers, weather widgets, etc. 
The battery life can be extended by individually setting apps to sync less frequently or by disabling background data and auto-sync.

Multimedia usage

Multimedia usage: Please be aware that any apps or content usage that keeps the device awake over an extended period will quickly drain the battery, e.g. reading books, playing games, watching movies, etc.

Signal bars

Signal bars: Check the number of bars that you normally see on your handset while at home or work. Using the handset in areas with very low signal uses a lot of power and therefore should be avoided if possible.

Latest available firmware

Latest available firmware: Software can be checked in Settings > About phone. 
Upgrade your software using either FOTA ('Firmware Over The Air', i.e. wirelessly) or via Samsung Kies.

No power up

No power up: If a device fails to power-up, the first thing to do is check carefully for damage to the power key or battery contacts. 
After checking, connect the phone to a working charger and leave it for a few minutes to see if it shows any sign of life. 
If the phone does not power up, then you may have a dead battery or a faulty charger.

Drop down Menu

Drop down Menu: Using this to toggle Wi-Fi, Bluetooth and GPS on or off. 
Switching these applications off when not required, helps to avoid unnecessary power consumption.

2 Select Settings.
