The single best Android app to extend your device battery life. A lot.

Airlock greatly improves the battery life of your Android device by putting it in Airplane mode when you're not using it. Airlock will make your device go on and on for a long time.

▶ This is the full unrestricted version. Please download "Airlock - Battery Saver Trial" if you wish to test it first for seven (7) days.

☆ Features
✓ Allow your device to periodically sync to keep your device up to date, even in Airlock-mode
✓ Auto start Airlock on device start-up
✓ Deny Airlock-mode when device is charging
✓ Optional delay before Airlock-mode is activated

☆ Why is Airlock so effective, how does it work?
The single most battery consuming action on Android is when your screen is activated and when your device communicates by using the network, which severely drains your battery. Airlock solves this by putting your device into Airplane mode when you turn your screen off which greatly improves the battery-life on your device.

☆ What level of battery-improvement can i expect?
The battery life improvement varies depending on the Android device, but will make a considerable difference to the overall battery life. The screenshot details idle usage for 24 hour on a Nexus 7 both with Airlock and without Airlock activated. Airlock is 275% more battery efficient in this test.

☆ Which devices are suitable for Airlock?
Airlock works on any Android device but is ideal for tablets (such as Nexus 7, Kindle fire and more), media players and android devices that aren’t primarily used as phones. The reason for this is that your Android device won't be able to receive any calls or messages when Airlock-mode is active since the network has been disabled.

☆ Can I still have some connectivity during Airlock-mode?
Users that still wish to have some connectivity during Airlock-mode can enable periodical syncing, which allows Airlock to enable network from time to time to allow the device to connect and sync with the network.

Please be advised that during this mode it’s still not possible to receive calls, but your device will sync your mail, calendar etc. While this option slightly degrade the efficiency of Airlock it still conserve a lot of battery.

    Saknar bara en sak. Att kunna sätta en tid innan den sätter tableten i airplanemode. Ibland lägger man bara ifrån sig plattan ett kort tag och vill inte att den dödar uppkopplingen direkt.

    Has been brilliant. So simple yet has saved me losing my mind. I download they trial and realised how much this could help. I have nexus 7 with a fold over case when I fold over it is like locking it air tight. Does what it says on the tin. Must have try

    Works well. When I'm downloading something all I need to do is turn off the app, and turn it back on when I'm finished.

    Great tool to increase battery life. Use on Nexus 7 no problem. Thunderbolt is another story. Slowed tb down and caused erratic performance. Phone would not work. I wiped device re-installed apps. V was the fourth one installed. Immediately my phone star
