Is there a way to make my phone turn off when the battery level is below 50%?
At the moment it does this when the battery level (or voltage) is critically low, but I want it to do it when there is still half the juice left.
A paid app would be fine too.
In Android, In order to shutdown or to reboot a device, programatically, based on certain system parameters (such as battery level), Phone needs to be ROOTED.
So, any apps that wants to achieve the functionality that you mentioned, can only Work on ROOTED Devices.
The closet app which offers Shutdown that I came across is "Shutdown Timer" by SpecSoft. https://play.google.com/store/apps/details?id=at.specsoft.shutdowntimertrial
Please note that this app does not shutdown phone when battery is low (which is what you asked), but allow user to "Schedule" shutdown.
I suggest you look at the app Tasker.
With Tasker you are able to literally automate your whole phone.
There are also many tutorials covering the of Tasker and what you can do with it (change settings and launch apps based on events, location, time and other variables)
As with many similar applications, this one needs root for many functions.
