My series 3's battery health is 85% and still last a full day and night with charging in the morning.

Redesigned Apple Watch Series 7 Could Prioritize Longer Battery Life Over Additional Sensors

All of the Series 6 reviews were unhappy with the battery life, with most knocking off at least a half a star. A wearable should have at least 24 hours of battery life, IMO.
I’m glad that the only big negative that the Apple Watch series has is being corrected.

2.5 days would be golden... that would cover a weekend, one less accessory to think about bringing along.
It might mean the difference between being empty at work if you forget /didn't have time to recharge your watch in the morning, to give one example. Or between needing to bring the charger if you are one night away from home.
What Apple should ideally be working on isn’t to cram a bigger battery into the Watch, but instead carve out some space in the case for a mechanical generator that could help extend battery life significantly or maybe even indefinitely. It’s the one thing I loved about my Seiko Automatic watch, that for the past 15+ years has never needed a battery, or service of any kind for that matter. Obviously the energy that a mechanical movement generates is tiny, but it would be producing it all the time as long as you’re moving.
I’m still on a series 3 as well, there just hasn’t been enough advancements to tempt me to upgrade since that model. Even with the cumulative features of the 4, 5 and 6, I’m still happy with my 3.
Each person to their own budget and requirements, I guess. Would be amazing to either have a big form improvements, such as making it thinner and/or expanding the screen into the chunky bezels; or, some biometrics that are really useful to the general relatively-heathy population.
Thank you! I never knew that was there! Must have been added in a watchOS release and I didn't explore the settings.
My Series 6 that I bought on launch day is down to 91% 
Yeah, I'm sort of split. Especially since you can turn off the always-on display to improve battery life, I feel like unless you get to the point where even after multiple days of heavy use you don't need to charge a device, then the battery life improvements in a tangible way are irrelevant for a large number of users (outside of stuff like having cushion for when the battery life does degrade.)
There's also just the question of what other sensors they can actually stick in the thing. If they figure out blood sugar monitoring (even if it's only roughly accurate) in a non-invasive way they will have made one of the most revolutionary medical devices in the last few decades, but since that's such a tough project it'll be a while before we see it.
To me, the Apple Watch is the only device I'd actually want to get a little thinner, and its bulbous shape is one of the few aspects that helps disguise how thick it is, so I'm not sure there's a lot of design wiggle-room to change things up, especially if they keep band compatibility (which they absolutely should as a core consideration.)
I'll probably still get a S7 regardless, because my S4 got smashed from a dumb choice to take it off in the bathroom soon after I got it and while it still performs like a champ the waterproofing is definitely shot. But it'll be curious to see how they can evolve the platform.
If only it had a self winding capability found on old mechanical watches.
You wouldn’t be able to produce even remotely enough power this way to make a difference. It works when you’re driving a mechanical spring but not when you’re powering LTE, GPS, BT5, WiFi, etc.. There’ve been some kickstarters that use kinetic energy and/or solar, but they are very rudimentary devices compared to the Apple Watch.
Don’t get me wrong, I’d LOVE if it could be done. I just don’t see it happening anywhere in the remote future.
Yeah, I didn’t mean to say that a mechanical drive would be enough to power a modern smart watch, but it could provide a trickle charge that extends the usable battery life. It just seems like a waste NOT to use the energy we generate moving every day.
I just pulled out my Seiko Automatic, as I’m going to pass it down to my youngest son. He has an Apple Watch, but doesn’t wear it because he works in construction and doesn’t want to destroy it - the Seiko with it’s heavy stainless case and band, and sapphire lens, will take the abuse, as it did for me. It also looks cool as hell and I know he’ll get a bunch of compliments wearing it.
Bring on series 7…battery life is getting bad on my series 6
I think the thing is, that with the amount of space given to a mechanical device to help charge the watch, the battery would have to be smaller still. It’s a nice idea, but outside of mechanical watches I don’t see that ever happening on an Apple Watch.
Strange, my Series 6 is running like it did new. I don’t use the always on display however.
Even as a trickle charge it would be useless. The estimated power consumption of a mechanical watch at about 3.7Wh over two years.
Is that a lot? Nope.
3.7Wh is about 3.2kcal (more commonly known as a Calorie among North American dieters and dieticians).
100 grams of peanuts contains 567kcal of energy, so 3.2kcal represents just over half a gram of peanuts. It just so happens that that is the weight of one peanut seed (i.e. the almost spherical thing of which there are 2 to 5 in a typical peanut shell).
So, it takes about one peanut worth of food to run your automatic watch for two years. Your watch literally runs on peanuts.
