Will my alarm still go off if my phone is on airplane mode?

Question

I'm trying to save battery but I need my alarm in the morning. Will it still go off if on airplane mode?

p.s. I have an HTC Inspire.

If you have an alarm app from the Amazon Appstore, you might have the opposite problem -- you might not be able to shut it off. I had Gentle Alarm and the alarm service ran fine, but to shut it off it opened the app which attempted a DRM check. The check failed due to no internet and the app closed, leaving the alarm running :P

Yes. Airplane mode (flight mode) only disables your phone's signal transmitting functions, not the functions that don't require a signal to function.

Your alarm will still work.

As @Jasir says. Your alarm will still work in Airplane mode.

Be careful as there is another setting on your phone.

Clock > Alarms > Menu > Settings > 'Alarm in silent mode'

You will need this ticked if you put your phone in silent (saving more battery) and still want the alarm to go off!
