How to Check the Battery Health on Android (And What to Do About It)
Battery life is something most people think about, but what about battery health? This is important for the long-term usability of your phone. Unlike the iPhone, Android devices don't have a super-easy way to check this.
What is battery health, anyway? The term "battery life" typically refers to how long the battery will last on a charge. Battery health tells us how much the battery is deteriorating. Low battery health means the battery will perform worse—discharge faster, get warm, etc.

That's all there is to it.
How to Preserve Battery Health on Android
Battery health is almost entirely tied to the number of charging cycles the battery has gone through. Simply put, charging your phone a lot is actually not good for the battery. Heat is also a bad thing for batteries, which can happen from overcharging—or just being left out in the sun.
This may sound counterintuitive to the "don't
