I can. Huawei Enjoy series can use a 40-watt charger. In particular, do not charge the battery from a very low percentage at once. Charging your phone's battery from a low 25 percent to 100 percent will reduce battery capacity and shorten battery life. Research shows that batteries, like people, do not want to be stressed, and do not always expect it to be overcharged. Charging to 100% from any level is not a good idea.
