Battery is not that important to me but im not confident that i can read on small 40mm model...

I had the galaxy watch 6 40mm for 1 week, and then brought the watch 6 44mm, what I got to say is that the difference between the two is kind of significant, the screen is mutch more easy to read and to use on a daily basis, and since the watch has a lot of controls and keyboard among another options on it, I think it's important to have a screen that is adjustable for your fingers, the other major difference is the battery, I wore the 40mm for a week, and it only lasted me about 25/27 hours, on a daily basis, and 10/15 hours when I used it at the gym, t was annoying because I had to keep an eye on the battery every time, I had my settings on low/medium battery consumption, and it still wasn't that good, when I went to the gym, It consumed me about 40% of the battery on only Spotify with headset, and a timer, for 1 hour, I had to charged it twice a day when I went to the gym, with the 44mm, the battery lastes about 40/50 hours on a daily use (low bright screen battery save on, LTE off) , it's about a 50% improvement on the battery, it last me about 2 days, or 1 day when I go to the gym, I think it's worth to buy the 44 if the price difference is under 50€, I hope this helps anyone who is wants to know what to expect

Has anyone used the watch 6 40MM that can report on the battery life? I keep looking for reviews on this topic but most people that cover the regular 6 and the classic, they tend to choose the 44MM regular 6 for review and neglect the 40MM. Would love to hear from anyone that has the 40MM. I suspect not many people will have conclusive findings just yet but I'd still appreciate your experience thus far.

I am considering to by my first smartwatch. I am confused between watch 7 and watch 6. I know watch 7 has a better CPU, GPS and sensors. But is it worth spending the extra money? Also does watch 6 get the features like energy score and galaxy Al from watch 7?
