We don’t appreciate electricity until we don’t have it.
When the power’s gone, there’s often still cellphone service. So if there’s a chance you’ll lose power, here’re some easy things you can do to stretch out the life of your cellphone’s battery:
1) Before the power goes:
Keep your cellphone plugged in and charging.
Charge your laptop. Later, don’t turn on your laptop, only use it for charging your cellphone via the USB cable.
Get a cellphone charger that plugs into a car’s cigarette lighter.
Turn off all the bells and whistles on your cellphone like bluetooth, feeds, and GPS.
2) After the power goes:
Keep your cellphone turned off when it’s not in use.
Try to only use text messaging instead of voice.
Turn down the screen backlighting as low as possible.
Use a flashlight or a candle for lighting not your cell phone’s light.
Your cellphone can last much longer if you’re careful with it and prepare a little bit ahead of a potential power outages, say a powerful storm heading your way.
