This depends on your usual degree of use, Huawei p40 battery in the case of full charge of heavy use can last 5 hours, including playing games, taking photos, video playback, phone calls, listening to music and other operations. If you only make phone calls and send wechat and other light use, more than ten hours of battery life is still no problem. I hope I can help you.
Normally, just watch the news and talk for about ten hours.
If you play games and watch videos, six or seven hours.
So it depends on how you use it, how often you use it.
