Most of your apps will generate money somehow. A famous music recognition app will determine your location every few minutes and send it to an ad network. Other apps will every few minutes download ads and act as if they show them to you. A weather app I once used at one point used android's voice recognition service for targeting ads (it transfered about a gigabyte of data a week whilst doing this). And some apps just try a bit too much to be informed about things they actually need to know.
Most android devices try to avoid waking up your device draining your battery for these reasons. And they try to be smarter than the app authors that try to be smarter than the device manufacturers. k9 regularly wakes up your device connecting the net in order to scan for mails. If it stops working for you the most probable reason is that your device misinterprets this behavior for draining the battery for no reason killing the app. On my own phone k9 works like a charm. But other apps required me to go to the "apps" section of my android section, to manually search for the "battery optimized apps" section and to find out how to add more apps to it after selecting "optimized apps". Needed a quarter of an hour to find this setting even if I knew it had to be there. Kind regards, Gunter.
