Question about OneBlade Pro - 546363

i unpacked the product and charged it for several hours because the battery was empty. a day later i couldn't use it because the battery was empty. then i charged it again and it showed over 50% after only a few minutes. after about two minutes of use it was empty again. after charging it again for 10 minutes, it showed 95% and for another 2 minutes of use, the 95% became 0%. that can't be normal to charge it so fast and then not use it for a few minutes. the final solution would be to send it back for repair, which is a shame.
