I cannot leave evernote running, I have to force close it every time I use it and this has been a long term problem that has spanned multiple versions of Android and evernote. Android marshmallow. Galaxy s6. It's approximately 1-2% per minute. I love the product but this needs to get fixed. There are plenty of other products out there but I suspect that none of them offer what many of us have come to enjoy. Edit: I went through all the settings and turned off the option to GPS mark notes. Not sure but that may be the ticket. Will update here if that's it.
