I've noticed that it used to take a long time to charge my device, but it used to hold a charge for 1 week. After the last update, I now notice my device charges a lot faster but only lasts half as long. Has anyone else noticed this?
Or do what this 4 weeks owner did today and let it run all the way down to dead, then plug it in for an hour and discover it only had a 3% charge. Pressed the button, triangle came up and then started charging at its normal, pretty-quick pace. Who really knows, but I'd guess charging while 'powered up" might be the way to go forthright.
