I have a Series 7 and I charge it on my commute to and from work. I also keep a charger at my desk in case I forget.

A Garmin

I bough the Ultra 2 just for this reason. It goes just about 3.5 days. I last charged it in Friday at 3pm and I just charged it for the first time since then. It tracks my sleep every night. I use the Auto Sleep app.

With my Series 8, I would charge up fully before bed, then put it on the charger while getting ready in the morning, where it would usually hit about 95% charge.

Wear it all day at work (8:30 - 4:30), and getting home in the evening, it would usually be at anywhere from 65-75%.

Just bought the Ultra 2, and don’t have to worry about that anymore. I’ve been able to wear it pretty much a day and a half without charging it at all, and it’s still at around 35-40%. Very happy I decided to get the Ultra.

I use it for tracking sleep, going to the gym, and even approving 2FA requests at work. It’s been a lot more versatile than I thought when I initially bought it.

I have the Ultra 1. I charge it for 20 to 30 minutes a night while I shower. This is almost always enough to get it to 100%. I charge it for maybe 45 minutes if I’ve had an especially active day.

I use about 5% to 10% of my battery for 7 to 8 hours of sleep with Sleep Focus on.

I exercise daily for a minimum of an hour (Exercise mode on).

I have Rise to Wake but do not use Always On.

I end my day (next shower / charge) with between 33% and 25% of my battery used. If I’m going on an overnight trip, I don’t even need to bring my charger. I don’t think I’ve ever used even 50% of my battery in 24 hours and that includes days I’ve been very active and tracked 3-5 hours of exercise.

I still have a 7, apparently battery life is just getting better and I charge mine every other night. I get two full days and two nights before charging. Ymmv

I have the 8. I throw it on the charger when I wake up. I charge it for ~20-30 mins and grab it on my way out the door. This routine has held up so far for me.

Every few days I have to top it off after work. I think it’s probably on days when I have to scramble out the door and it gets less morning charge time.

Charge it while on the throne in the am and then while in the shower after working out.

I bought an Ultra specifically for the longer battery life. Sleep tracking has helped me become a better sleeper.

I take off my watch to charge it and boom, it lasts when I need it to. Pretty wild how that happens.

Bought an S9 on Black Friday after some time wearing Casios now I’m back. I also bought it for sleep tracking and regular use - I rarely do workouts, so I know that takes up a lot of battery life.

So far, it’s lasted 2 days on one charge. I normally don’t let it die completely, since I like to have enough juice to wear it at night. It’s got raise to wake on and I’ve tried to turn off somethings that will drain the battery - if anyone has any tips on what drains, please help me here, sometimes I really don’t know what to turn off, lol.

And it charges quite quick I think, about less than an hour it’s good to go. Don’t be fooled by the ‘faster charge’ on the 8 and 9 models. It’s literally 15’ faster on a charge than the regular one, it’s really a joke, if you ask me. A ‘faster charge’ would be like 30 minutes vs an hour imo, but it is what it is.

Overall it’s an all day watch really. Apple Pay is absolutely perfect and blazing fast, watch faces are great, all apps I need work perfectly well, the larger screen is great and the S9 is a good watch if you wanna track your sleep, since it’s not uncomfortable to wear at night.

Ultra

All day and overnight? Will this include interacting with the Watch as well, or just looking at it?

Just charge at the evening works with my S6 with 80%

I will be honest here and I might get downvoted to oblivion since this Apple Watch group. I used a Huawei band that is like $20 only then after that, a Huawei smart watch. Very straightforward, just wear and it will automatically track your sleep, Awake, Light, REM, Deep, etc. No complications! The battery lasts for more than 5 days. I recently upgraded to AW thinking that it could be better but to be honest, it’s just basically the same. The Huawei has blood oxygen monitor too but my SE which is a bit more expensive than the Huawei doesn’t. Going back to sleep monitoring, I found the Apple sleep monitoring too complicated, maybe because I came from something that doesn’t require something like setting bedtime, sleep focus, and I even ended up getting a 3rd party app so I can track my naps. If you need sleep monitoring, maybe you need to look somewhere else. I am not saying Huawei because if you are in the US, then you might not have it but there are better sleep tracking watch out there for sure. I know some folks here are recommending Ultra but I don’t see the point of spending almost a thousand dollars just to get extra days of battery life so you can track your sleep.
