How to maximize battery life when you travel

By Leah Yamshon, Macworld |  Mobile & Wireless

It isn't necessary to bring both the charger that came with your iPhone and the one that cam with your iPad. Save space by packing just the one that came with your iPad. Visually, the iPad charger is bigger, with prongs that can be pushed in and pulled out of the square body, similar to a MacBook charger; the iPhone charger is smaller, and its prongs can't retract.

But what if you have an iPhone 5 (with a Lightning connector) and, say, a third-generation iPad (with the older 30-pin dock connector)? You can still pack just the iPads larger wall charger unit and bring both your Lightning-to USB-cable and your 30-pin-dock-connector-to-USB cable, or pack a Lightning-to-30-pin adapter if you have one.

iPad and iPhone wall chargers supply different levels of power. The iPad's greater charging requirements demand the heftier power adaptera 10- or 12-watt USB power adapter depending on your iPad, compared to the iPhone and iPad minis USB power adapter, which has an output of 5 watts. You can use the iPhones adapter for your iPad, but the device will take significantly longer to reach a full charge, especially if it's a third- or fourth-generation iPad.

If you travel with a MacBook as well, you might want to get the Twelve South PlugBug ($35). It attaches to your MacBooks power brick and allows you to charge a USB device (such as your iPhone or iPad) and your laptop at the same time.

Tweak iPhone and iPad settings

Conserving your battery's charge can be as simple as tweaking some settings on your iPhone and iPad.

Turn off wireless options: Turn off Wi-Fi when youre not using it. Go to Settings > Wi-Fi, and then toggle the switch to Off. The same goes for Bluetooth: Turn it off if youre not using it. In this case, go to Settings > General > Bluetooth, and toggle the switch to Off.

Turn off notifications: Turning off or limiting your data push-notifications from your other apps is worthwhile, but youll have to do it manually for each app. Go to Settings > Notifications, tap each app that youd like to adjust, and toggle the Notification Center switch to Off.

Turn on Airplane Mode: Turning on Airplane Mode disables all of your device's wireless featurescellular data, Wi-Fi, Bluetooth, GPS, and other location services. Go to Settings and toggle Airplane Mode on.
