UMI Iron not charging

rolo

I'm having the same issue on my Umi Iron with the Usb port. I got it since about 8 months now. It's very loose and tried several cables including the original one. Additionally sometimes the percentage is stuck on a certain level and doesnt seem to go up, sometimes it goes up pretty quickly. The drainage seems to be high too even though there are some apps running. Also tried the Battery calibrate. I was wondering if the battery got some issue too then
