October 2, 2012 (WPVI) -- All that multi-tasking your smartphone does on a regular basis can drain your phone's charge in a flash. Here are some simple tech tweaks to boost your battery life.

1. Avoid Power-Zapping Settings: Turn off Wi-Fi, Bluetooth, and other location tracking services when you're not using them. Also set your ringtone to silent or quiet over vibrate, which uses more power.

2. Fetch data less frequently: Your apps and e-mail may be updating even when your screen isn't on. Change your settings so there are longer intervals between data refreshes.
