Battery Care Tips
Getting Started
Charge your new battery fully before you use it for the first time. Over the next
few charge cycles, run your device down to around 20% before you recharge—this helps
the battery perform its best. After that, charge whenever you need to.
Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both
extremes wear it out faster. Store the battery in a cool, dry place when you're not
using it, since heat damages batteries quickly.
