I've had my note 10.1 for over a year now and it's always done well with charging, using the OEM charger and cable. I've used several different roms and no difference in charging. I recently installed Gnabo V3 and it's been no different for over a week. Starting last night, it's charging very slowly. For instance, I was down to 21% this morning. I put it on the charger seven hours ago and it's only up to 73% now. I did install the Xposed framework yesterday but would that make such a big difference in charging?? The only module I installed was Gravitybox, and that was just to add buttons to the navigation bar. I plan to uninstall Xposed and see if it goes back to normal, but wanted to share my experience and see if others have had similar issues.
