Tip 1 – Set the phone to sleep right after you’re done using it by pressing the power button quickly
This will turn off the screen but NOT turn the device off.

If your phone is constantly syncing, it will continually use the battery.

Software updates can resolve issues and improve device performance.

Unless you change an application’s settings, it may continually run in the background and syphon your charge.
Tip 5 – Lower screen brightness and the shorten the timeout
The screen on the device is a big drain on the battery life. You can double the life of the charge by simply dimming the brightness.
Tip 6 – Turn off connections
Connections such as a Mobile Hotspot, Bluetooth, GPS, and if you don’t need internet – your Wi-Fi.
Tip 7 – If you’re not in need of a cellular network, you can switch (via settings) down to 2G speeds
2G uses less data than 5G or 4G.
Tip 8 – Uninstall apps you don’t use
Similar to turning off background data, simply uninstalling unused apps is a great way to save battery. You might not realize the drain they’re putting on your battery.
