Have a nice day. I have Oneplus 5 phones. While playing with the phone, the battery ran out and turned off. Then I tried to turn it on several times by pressing the power button but it didn't turn on. In my last press, a screen came and went 'battery low' and something Chinese came out. Then it closed again. Then I overcharged the team, but no more charging half a day barely enough. What is the reason? How can I fix? Can you help me, please?
