Preserving Battery Life
Here are some suggestions for preserving battery power. You can become familiar with these options and turn them on or off as needed. Many of these features can be accessed from your phone's Settings menu.
- Disable Wi-Fi, Bluetooth, and GPS or location-based services when not in use.
- Turn the screen's brightness level to the lowest comfortable setting.
- When not in an LTE-coverage area, disable LTE capabilities. When you're in an area with limited signal, your phone will constantly look for a better connection and will use battery life doing so. You can re-enable LTE when you're in a more populated area or when you have access to a power source for your phone.
- Turn off the vibrate function. The vibrate function uses additional battery power. Also, keep the ringtone volume as low as possible.
- Avoid letting your phone's battery run all the way down. Most smartphones today use a lithium-ion battery. Unlike nickel-based batteries (such as the NiCd or NiMH rechargeable batteries used in products like flashlights and remote controls), lithium-based batteries are designed to be charged early and often. Letting your phone's battery get too low can damage it. With lithium batteries, doing shallow discharges and frequent charging prolong battery life.
- With a smartphone, avoid using moving or animated pictures or video for your screen's background. Animated backgrounds will drain the battery faster. Also, on phone's with an AMOLED screen (like Samsung Galaxy models), use a dark background when possible. AMOLED screens use a lot less power displaying darker colors than lighter colors.
