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.

I have a 6 with about 85% battery life left. I wear it all day, and leave it in the charger an hour before I go to bed, then wear it at night.

In the 2 years I’ve been doing this I’ve had maybe 3 times where the watch didn’t make it till the end of the day. Most of the times because I had used it for navigation, or some background process had been eating my battery.

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 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.

I have the SE 2020, lasts almost 2 days usually. I charge it while I’m in the shower and it’s more than enough (I take quite long to shower though).

I have the SE and can wear it for 2+ days without a proper charge if I just charge it when I shower in the evenings. :)

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 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 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 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.

I have Series 7. I charge it once day at morning while I am getting ready for the day. This also includes a workout session and sleep tracking.
