Have had the watch a week now, wanted to really test before I reviewed it. It's a really great watch. I'll qualify that saying 'for the money' but really, overall it's a great watch regardless of price.To start off, the watch came charged up at 95% (still in original packaging, including seal, so referbished in this case must have just meant returned without opening.) Took just minutes to get to full charge. The battery lost 50% the very first day, but chalk that up to downloading a bunch of watch faces, and adding songs. I recharged it after that first 24 hours just to get a fresh start with actual use. The second charging from 50% took about 30 minutes, not bad at all. This second charge lasted 5 days (exactly to the minute) and still had about 33% left which is roughly how much per day it used, so could have possibly made it until 8 pm the next day making it 6 days, but I had things to do in the evening and I didn't want it dying while I was out. Features wise, it has everything and everything but the always on, was on the entire 5 days. It tracks well and gives good info on all of it's functions.I am really impressed with this watch. It is a BIG face, but it is comfortable and I am a woman with thin wrists and it's still comfortable and not intrusive. Lots of watch faces to choose from, although some were not free, and of course, my favorite one was 2.99, but worth it, I like it. There were lots of free ones though that were very nice as well. I switched around a lot between the ones I loaded to the watch until I finally did decide my favorite was the one I paid for. The third charge starting at 33% only took about an hour to get to 100% (have to say though that the last 3% seems to take longer than the entire first part of the charge up, lol). It is very fast charging and does indeed hold the charge a long time.If I turned off some of the other features it would probably easily get 8 to 10 days, but that kind of defeats the purpose. Still, 5 to 6 days for a single charge and a fast recharge time makes it better than many of the top of the line expensive fitness watch.
