Thanks for your answer. I actually replaced the battery in February of this year. The viewer assured me it was an original OnePlus battery. The important thing is that everything else works for now. Thanks again for the answer.

Hello, I installed Ubuntu Touch on my oneplus 1. The battery settings always show 50% charge, even if the battery is charging. The phone works correctly but does not update the recharge data. . No do I report the recharge status if connected with USB. It is possible to do something. I await your reply thanks.
