How to Charge Your Phone Properly to Save The Battery What’s the best way to charge your smartphone? Avoid full cycle (zero-100 percent) and overnight charging. Instead, top-up your phone more regularly with partial charges. Ending a charge at 80 percent is better for the battery than topping all the way up to 100 percent. Use fast charging technologies sparingly and never overnight. Heat is the battery killer. Don’t cover your phone when charging and keep it out of hot places. Turn your phone off when charging, or at least don’t play games or watch videos to avoid mini-cycles. You should keep these tips for your xiaomi watch or any other smartwatches for the future references.
