Quick FAQ
While modern devices have protection circuits, regularly charging to 100% can accelerate long-term wear. For maximum lifespan, keeping between 20-80% is ideal.
Fast charging generates more heat, which can degrade batteries faster over time. Occasional fast charging is fine, but for daily use, slower charging is better for longevity.
A battery cycle is completed when you've used 100% of the battery's capacity, whether that's all at once or in smaller amounts that add up to 100%.
Overnight drain can be caused by background apps, poor signal strength, or system processes. Checking battery usage stats can help identify the culprit.
