Here are 10 survival tips that will help you make the most out of your battery. If a power outage hits your area, you'll know exactly what to do to ensure you remain connected.
Turn off the extra wireless connections
Your phone has a myriad of different connections, few of which are really that integral during a blackout. Wireless connections such as Bluetooth and WiFi are great during a regular day, but they can quickly drain a battery. In power-saving situations, GPS is also a no no, and disabling location services is another smart move.
Resist the urge to check your phone
For most of us, the smartphone is the equivalent of a drug -- one you can't quit. Well, a blackout is a good chance to go cold turkey. It's smart to limit the use as much as possible. Each time you turn on the display, you're cutting into the phone's battery life.
Share phones
If you're with a group of people, it might be useful to shut off all but one of the phones. That way, if one goes down, someone else can turn on a phone that still has a full charge. Of course, it might be handy to take down some critical phone numbers before turning off the devices.
Switch to airplane mode
If you don't want to completely shut off your phone, switch to airplane mode to shut off all of the radios, and switch back out of airplane mode only when you need to make a call or send a text message.
Keep your phone plugged in before a blackout hits
If you still have power and are looking to limit your usage already, why not let your phone rest near an outlet? When the power goes out, you'll know your phone is holding as much of a charge as it possibly can.
Charge backups
If you're lucky enough to have a phone with a swappable battery, as well as an extra battery, make sure that backup is fully charged before a blackout hits. Alternatively, a fully charged laptop can also be used as a battery of sorts, since it can charge a phone through a USB connection.
Disable push notifications
Most smartphones are hooked up to one e-mail account or another, and these devices either get messages pushed down to them or they fetch the e-mails. You can save a lot of battery by turning off the push notifications.
Take a break from streaming
If you have to listen to music or video, don't use streaming services, which constantly puts a strain on the phone's battery. Only play videos or songs already loaded on the phone. Likewise, try not to play games that require a connection, like "Pokemon Go" or "Candy Crush Saga," or games that require phones to rev up their processors, such as the "Infinity Blade" series.
Dim the display
Displays often take up the most power, particularly if the phone has a large and bright screen. Most phones have an automatic brightness option, though you could manually dim the screen to preserve battery. Lock the phone and turn off the display as much as possible.
Send text messages instead of calling
Because of the nature of text messages, the conversation is usually kept short and concise. Phone calls can drag on, sucking up valuable battery life, but a text message gets the information out far more efficiently, and isn't constantly running.
