app that do almost nothing (draw some text every minutes) consumes a lot of battery

So:

- is it mean that is impossible to write app saving battery due to it's run always in high power?

- when I go to activity but not start it, there is info "going into saving battery" - it means it is impossible to change power mode - but not for ciq app unfortunately, it will be useful to add this for developers maybe only to go into low power

I've read  some developers description of their app and they the same problem like me:

https://apps.garmin.com/en-US/apps/4c8224d3-1442-4c26-b253-22f624f38e33

It works but the battery drain makes it pretty unusable. With 8 hours sleep I used 25% of the battery (on my 735XT) and 17% on another night. The other similar app I've used is around 10% per evening. Not been updated in many months so won't assume this will be improved.
