Maximize battery life and keep devices running when you can't recharge.
When the grid goes down, your battery-powered devices become your lifeline — phones for communication, flashlights for light, radios for information. But batteries are finite. Knowing how to conserve, prioritize, and extend battery life can keep critical devices running for days or even weeks longer. This guide covers phone battery optimization, battery rotation strategies, storage best practices, and improvising power from unexpected sources.
Step 1 of 7
Rank devices by importance: 1) Phone for emergency calls, 2) Radio for information, 3) Flashlight, 4) Medical devices. Conserve power on lower-priority devices first.
Pro Tip
A phone's most critical function is calling 911. Even with 5% battery, it can make emergency calls.
