Google Pixel - Pixel Watch 3

If I'm not active my PW3 45mm lasts me 2-2.5 days. If I use the GPS a lot it's more like 1.5 days, all of that using AOD.

I have a physical job so I'm somewhat active. My Pixel Watch 3 45mm can last 48h with AOD if I don't workout or 36h if I do some workout/jogging after work. Do you have the PW3 41mm?

My new 45MM PW4 came off the charger (after applying the OS update) last night around 7PM. I have always on display on, tracked a one hour spinning workout, and I am sitting at 74%. I came from the 45MM PW3, which was getting me almost 2 days from a full charge (more like 40 hours), so I am very curious to see how this goes over the next few weeks.

30 hours of battery life! These guys are getting WAY ahead of the competition here with this release! /s (For context, I am wearing a PW 3 45mm LTE right now and the battery life is just "fine" and never groundbreaking. The OnePlus Watch 3 that runs the same version of Wear OS can go for DAYS)

I agree about the difference in the health sensors and that was one of the reasons why I ultimately have the Pixel Watch on my wrist right now. I also wanted LTE and the OnePlus does not offer that here in the states. I did buy the OnePlus watch and tested it for about 2 weeks before I returned it back to them and so I feel like I have a pretty good idea of how that watch operates. I was using a 3rd party watch face the whole time and I had AOD always on except for the auto sleep mode. I could *easily* go from a Friday morning to almost Tuesday morning with that setup. I was wearing a Whoop strap at that time and so I changed the Continuous HR monitoring to the Automatic Mode. *** The other REALLY big difference, and I've tested this on many Android watches, is the Raise to Wake feature - no matter if you have the AOD on or off, that feature adds to the battery drain because the accelerometer is constantly watching to see if it needs to activate the screen. If you can turn it off, on any watch, you will see a marketed increase in battery life. *** I wear my PW 3 with the AOD set to On, except for during sleep, and I can get about ~2 days max. Because PW uses a proprietary cable I cannot leave for a long weekend with my watch and not have to also take its proprietary charging cable along with me. From a purely battery standpoint - I could leave for a long weekend with the OnePlus watch and not even have to think about taking it's charging cable with me. That may seem like a small thing but I really liked that a lot about that watch. And if you did somehow manage to drain the majority of the battery you could switch it to its low power mode OS and it would easily last for 5 days more which is incredible.

OP, I know you are likely an Android user, I am as well, but I'm always looking at what else is out there as technology as a whole interest me. If you watch the videos from The Quantified Scientist on YouTube, the Pixel Watches are of course up there with his measure of data accuracy. Time and time again though the one that stands out above the pack seems to be the Apple watches and their heart rate sensor. Have you ever looked into an Apple Watch? There is a very popular third party app called Athlytic which can give an approximation of VO2 max. I've read time and again that the app gives a very much Whoop like experience. For context and whatever this is worth I'm currently wearing a Pixel Watch 3 45mm LTE and an Oura Ring 4 as well. I'm just fascinated by tech and how it can help improve our lives I'm just not as dialed in to my fitness currently as you are.

I guess that It always depends on what you are doing with the watch : My PW3 45mm is at 14% after 70 hours

I find it's better to get what brand you're using with its correct brand.    My galaxy watch 5 Pro did not work with my Pixel 9 well at all. Main reason was that no matter what I did, factory resets etc, I just could not get notifications to work at all. Also some fitness stuff and sensors only work with the right brand. So I got a Pixel Watch 3 45mm and it works perfectly. It's also much smoother and the software is a lot better than my galaxy watch. Only downside is that you have to pay for Fitbit premium otherwise free version is perfectly fine. 

Yeah get a Pixel Watch 3 and you'll be much happier. 

The battery life is very good on my Pixel Watch 4 45mm too. I just hit 50% battery (started at 100%), after 39 hours. Assuming it's linear (which is not always the case) I'll be able to get close to 80 hours battery life, or three and a quarter days. On my old Pixel Watch 3 45mm, which I still own, I was able to squeeze out about 52 hours on one charge with the same settings and same watch face and same usage pattern (or as close as I can get). So.. going from 52 hours to \~80 is a massive improvement. Remains to be seen though if the battery level indicated is accurate and linear. Would not surprise me if the remaining 50% will drain faster than the first 50%.

About 61 hours now, and 21% battery left. Estimated total battery life by the time the watch shuts off is currently just over 77 hours. That's almost 50% better than my Watch 3 45mm with same settings, same watch face and same usage pattern. Or as similar as it can get, at least. There are of course slight differences, this is not exactly a controlled experiment in a lab. Still, very impressive battery life if this holds up. Will update again tonight.

Final update. Just hit 72 hours, three full days, and there's 7% battery left. The battery saver kicked in at 15%, so in the end I think I would probably have been able to hit about 80 hours total, but I am going to sleep soon and I don't want it to shut down in the middle of the night, as I want to track my sleep. I am very happy with the battery improvements compared to the Pixel Watch 3 45mm.

Switched from Samsung Galaxy Watch 6 Classic LTE to Pixel Watch 3 45mm bluetooth . Used to own a Galaxy Z Fold 4 pairing with the watch. Then switched to Google Pixel 9 Pro XL a year later after having an issue with the phone and claimed the warranty, then sold my galaxy watch to my friend and bought the Pixel Watch. Love the Pixel Watch battery life, 9 hours working drop from 100% to around 75%, sometimes 71% but still better than the Galaxy Watch, can't stay alive that long( battery saving On, LTE Off, AOD Off). Pixel Watch is set to AOD On, battery saving off, gesture tilt to wake off. Also the smoothest is also better, than sometimes the Galaxy Watch doing some lagging on the animations. But the classic looks on the Galaxy Watch 6 Classic is amazing and of course I love the rotation bezel. But the Pixel Watch has the rotating crown and it is just beautiful.

I think wearOS 6 greatly improved battery life for my pixel watch 3 45mm LTE I'm at 35% battery after over 1.5 days of usage and that includes going on a 10.5 mile bike ride w/LTE on

Pictures I can't see and music I can't hear two valid points. He he. I have the 45mm and YouTube music and favorites downloaded to watch so I can connect my buds and enjoy. Love my watch and your points are kinda meh.

Hot take from someone who's been using the PW3 45mm since release - This comparison means nothing unless you have a medical grade heart rate monitor to compare both the watches values with during these sessions.

Might wanna ask OP that. My whole point was that this comparison is useless without an accurate base line.
