battery guru is reporting that my battery health dropped to 89% (4010.1 mAh / 4500.0 mAh) and all I have done is charge to 100 one single time! is there a chance that this is reporting incorrect values? anyone that can shed some light on the best practices for charging our phones I'm all ears. for example, I read that charging to 80% is optimal, and that fast charging essentially damages the lion battery, or in short, everything that gives us convenience with charging is working against battery longevity. so should I simply top off my battery whenever it gets near 20% and only charge to 80%? any input is appreciated. I am trying to keep my op9pro for at least 2 years and maintain maximum battery health, and I already lost 11% health?!
