Just want to share on Fitbit Versa battery issues. I have used mine for less than 4 months when the battery life deteriorated to 2 days maximum. I practically charged it every day from July to most of August. Last Sunday, the battery went flat, and I didn't realise. I charged it and forgot about it as I was busy. By the time I put on my Versa, it had already been left charging for 6 hours. To my surprise, the battery life improved significantly after that. It was at 24%, after close to 4 days on Thursday (yesterday). I decided to charge it in the evening. Now the battery is showing 90% after more than 12 hours. I did turn off Quick View and my display setting is Dim. But I set the vibration to Strong.
I was quite frustrated when I had to charge my Versa almost every day. During that period, I charged between 40 minutes to 2+ hours each time. Still, it gave me poor battery life. Now that it is doing well again, I hope this information would help anybody experiencing my previous frustration.
