Most Android users have a love/hate relationship with their Wi-Fi capabilities. On the one hand, it's great for keeping data and voice usage down; on the other, Wi-Fi use can kill our batteries, especially if we keep it powered on while we're out and about. Sentry lets you set up rules about when to turn Wi-Fi on, which should help improve battery life significantly. Here's how to use it:
- Download and install Sentry here.
- Run Sentry and set it up. You can turn notifications on and off and have Sentry check for connections even if you've turned off Wi-Fi. Further down, you can limit the time Sentry checks for connections before powering down Wi-Fi, tell Sentry to keep checking every so often if it doesn't find a network, check the connection every time you unlock your device, and start Sentry when the phone boots.

- Note that when you're done setting this up, you will need to click the "Activate" button at the bottom of the screen. On my phone (and screenshot), it's kind of scrunched down and hard to read, but once you tap it, the button should widen and show a green bar after a few seconds.
That's it! Sentry is easy to set up and should prolong battery life for Wi-Fi users. Remember, you can still override Sentry and turn Wi-Fi on or off depending on your needs.
