Hurricane Irene is set to arrive in the DC area tomorrow afternoon, and with it possible power outages throughout the Metro DC region. Here are a few tips to keep your iPhone lasting as long as possible:
- Turn off Push Notifications. You really don’t need a message from Facebook that Janie’s dog did the cutest thing. Settings > Notifications > Off
- Turn off Bluetooth. You’re not driving in a hurricane. Turn off Bluetooth to save a bit of extra juice. Settings > General > Bluetooth > Off
- Turn off 3G. The goal here isn’t updating Twitter or keeping up on work email, it’s preservation of the phone so you can call Pepco or BG&E when the power goes down. Moving to EDGE data will help. Settings > General > Network > 3G Off
- Turn off Location Service. If you’re hunkered down, you know where you are. You can always turn this on for a bit to see where the nearest pizza place is: Settings > General > Location Services > Off
- Turn off Push email & calendaring. Again, this is a hurricane, so you don’t need that calendar invite from your cousin right away. Same for the email from your mother in law. If they need you, they’ll call, which is what we’re saving battery for. Settings > Mail, Contacts & Calendars > Fetch New Data > Push: Off
- Turn off auto-check of email. If you’re important enough to need this, you’re important enough to be somewhere with a gen-set, a massive flywheel UPS, and redundant bandwidth. Turn it off. Settings > Mail, Contacts & Calendars > Fetch New Data > Manually
- Turn down your screen brightness. Given how dark these storms are, you can lower your brightness from blinding to dim. Settings > Brightness
- Shorten your auto-lock period. See previous statement about hunkering down. This is more to save battery than be convenient. I’ll forgive you for turning off your passcode (if you can) for this weekend, if you want. Turn it back on Monday. Settings > Auto-Lock > 1 Minute.
- Make sure to kill graphics-heavy apps like Angry Birds. From the home screen, double-press the Home Button, then press and hold on the app icon, then hit the red minus at the top of the icon in the switcher tray.
- If coverage goes out, switch to Airplane Mode. In the event of cell coverage going out, or worse, getting spotty, switch to Airplane Mode for a while. Searching for signal is very battery intensive.
Alright, that ought to do it for now. Good luck & good hunting.
