Use a wall charger:
If you have the ability try to avoid USB cable charging from a computer or vehicle. Wall charges are faster, and your charge will last longer.
Adjust Screen Time Out:
Long screen timeouts mean your screen will stay lit longer after you have stopped using it. Set it to a lower value to save battery power.
Avoid poor signal quality:
If you’re in a low signal area, your phone will boost its signal power, thereby consuming more battery.
Reduce screen sensitivity:
Consider reducing your touchscreen sensitivity, because the more sensitive your screen is, the more battery power it will use.
Lower screen brightness:
Screen brightness is one of the biggest usages of your battery power. If you don’t need it bright, turn your screen down.
Turn off GPS:
If you’re not actively using your GPS or Navigation software, turn your phone’s GPS off.
Turn off location services:
Location services often transmit and receive signals to identify your location. This can consume considerable battery power. If you don’t need these services, disable them or turn them off.
Close your Applications:
Many programs continuously run in the background, using battery power. Closing them down will help save your battery consumption.
Avoid live themes and wallpapers:
Themes or wallpapers that contain animations are constantly ‘doing something’ will therefore consume battery power. Consider avoiding these.
Drain your battery monthly:
For lithium based batteries, manufacturers recommend using all of the power in your battery about once a month. Then, charge it fully before unplugging the charger for optimum use.
Avoid metal exposure:
Exposing your battery to excessive heat can damage your battery permanently, especially if your battery is at 100% and exposed to direct sunlight and/or heat.
Lock phone immediately after use:
Don’t wait for your screen to automatically turn off, this will consume battery power. Once you’re done using your phone, immediately lock the keypad and/or screen.
Don’t cover your light sensor:
Most phones have a light sensor, located near the top of the phone. It automatically adjusts the brightness of your screen, so if it is covered or obstructed, your screen brightness will increase.
Store phone in case or holder:
If your phone is in your pocket or bag it can often get bumped. Some of these bumps will inadvertently press buttons, causing your screen to light up.
Turn off flash:
If you do not need a camera flash, turn it off. It consumes a lot of battery power when turned on and used.
Turn off vibrate:
Unless you need it, turn off the vibrate mode. It uses more battery power than a ringtone or silent mode.
Use dark wallpaper:
Bright colors on the screen consume more battery power than darker colors. Consider changing your wallpapers to darker colors.
Use less intensive graphic programs:
Programs that have high intensity graphics, especially games and video streaming, will drain your battery quickly. Try using only if necessary.
Disable social media feeds:
These feeds are always constantly checking the internet for new updates, which consumes battery. If you want to use social media feeds, set your update frequency to a smaller time frame, otherwise do without them.
Avoid temperature extremes:
Batteries do not like extreme changes. Anything higher than 95° Fahrenheit will decrease your battery’s charge. The same thing applies to freezing weather conditions.
Change your notifications:
If you receive a lot of text messages or calls, change your notification to a short sound clip instead of long ringtones or vibrations.
Lower music volume:
Listening to loud music, whether through your headphones or the phone’s speaker will consume more battery power than quieter music.
Avoid task killers:
Beware of task or process killer applications, they often cause more harm than good.
Watch third party apps:
Applications that are poorly designed or coded can often consume more of your cell’s battery life than necessary. Apps made by larger companies will typically have more battery efficient code than those created by smaller third parties.
Change photo effects:
Applying filters to your photos consumes more processing power and therefore more battery power. To conserve even more power, turn these effects off.
