The Ratio launcher uses much more battery and battery drains super quick.
Earlier I used to charge my OnePlus 7 Pro once a day and it used to breeeze through all the day.
But now I have to charge in less frequent interval than before.
If there are any background activities that are running, I think only the necessary activities should run. Because being a minimal launcher, the battery should last longer as we are trying to achieve less usage of phone which in turn should lead to less battery consumption.
