Should i invest in a pokemon go plus?

Honestly ive been watching a lot of reviews and comments about how pokemon sleep drains the battery health of their phones, and yeah, ive been using pokemon sleep for two weeks and my battery health was 94% and went to 93%. Should i invest?

Edit: TO BE COMPLETLEY CLEAR: im not trying to trick the app, i use this app to fix my sleeping habits because i like pokemon and its like an incentive for me, im not on the meta or anything, i just like the game for what it brings me
