Well, this is the first week where I got battery life anxiety and actually recharged mid-week (normally only charge once a week and still have around 50% battery life - and that is with approx 1hr per day of tracking too). It is also the first time in a long time that I have taken a watch cable with me on a week's holiday.
But then I was tracking +2hrs of activity every day (yes mainly GPS); and when I did recharge was around 50%. And then this morning when put on recharge was around 55% so all told might have just made it. But was quite novel having to worry about battery life for the first time in quite a while.
Not an issue for me, as this will only happen a couple of times a year, which way out weighs the cons of the F7 MIP screen.
