I bought my husband the ipv mini for Christmas and for some reason it keeps shutting off on him. When it shuts off in order to get it to turn on again he has to take the battery out and put it back in. We just bought new batteries and it happens even with a full charge on them. Has anyone else has a problem with this and know how to fix it or have any ideas of what is causing this? I use mech mods and am not familiar with regulated so I'm no help to him. Thanks.
