Lately, I've observed that my iPad battery drains more quickly when I do not kill the MobileSheets app after using it. It's most apparent if I leave my iPad alone overnight. Without MobileSheets loaded in the background, the battery % level hardly ticks down. Not so if I have MobileSheets loaded. A few days ago, I was surprised to find one of my iPads fully drained - that almost never happened before.

In a couple of the situations that I made these observations, the iOS battery settings panel pointed to MobileSheets as the primary consumer, but I run the app a lot anyway which would make it rise to the top regardless. These are hardly scientifically controlled tests.

I know that there are several MobileSheets settings that affect battery performance. Is there a comprehensive list of these available that I can check out? Do any of these options matter when the app is only in the background?

This is only a suspicion at the moment. I'm curious to know if any other users have observed the same. I wish I had the tools and expertise to provide more concrete data here. Apologies in advance if this is a false alarm.

I always close MSP down when I stop using it for the same reason (android)

I don't know about you but I always have the metronomne running when songs are displayed and this also puts a significant drain on the battery (I suspect the metronome is still running when the tablet case is closed and MSP hasn't been shut down)

@Geoff, Thanks for chiming in. Good to have a corroborating perspective. I've wondered, too, if this might be metronome-related. I always have the metronome running myself.

If I run a simple test (load the app, load a song, start the metronome, stop the metronome, then pause the app), I'm not seeing any processing being done with MobileSheets in the background. I do think there may be scenarios where Apple's audio framework could still be processing and causing battery drain though, so I'm going to add some code to force the current audio session to be stopped if MobileSheets is put in the background (if the option to play audio in the background is disabled) or the screen is turned off. We can see if that helps with the battery drain.

Many thanks Mike

Thanks for looking into it Mike. By the way, what happens if you leave the metronome running before putting the app into the background?

I'll double check, but it should automatically be stopped and the audio framework should be stopped as well.
