I had AOD on for half a day when i first set it up. For me I don't find it necessary and turned it off. Cellular is off. I do exercise at least every other day. On my first charge that lasted 3 days I had two exercise sessions. I am using the modular ultra face with all the complications active. The compass and elevation are constantly updating, and I imagine they use up some battery.To all of you saying that Ultra 2 can last 3-4 full days I have one question. How in the world? Do you turn off AOD, turn off cellular, what else is turned off? With both Ultra 1 and 2 I barely pass 48 hrs with no gps on, no exercise. I do have cellular on all the time and AOD on on lowest brightness.
Thanks for the info. That would make sense with AOD off and cellular off.I had AOD on for half a day when i first set it up. For me I don't find it necessary and turned it off. Cellular is off.

I do find that it charges a lot more slowly than my S5 did. Perhaps due to a bigger battery? I am still using the charger from the S5, using a 5W iPhone charger. I'm OK with it. Maybe I'll just charge it to 80% on each charge which should still last two days for me, and help with battery longevity. I've also set my iPhone 15 Pro to 80% charge.
Wow, that's amazing!My SS S9 is at 67% battery left at bedtime each night since I started wearing it.
I have found on both my Ultras that having cellular turned on, even when connected to phone, eats up more battery than when cellular is off. I am guessing having cellular on powers up the cellular chipset even though it is not active which consumes power. I turn my cellular off unless I go for a walk or go to the mall and leave my phone behind.To all of you saying that Ultra 2 can last 3-4 full days I have one question. How in the world?

Would be really interesting for Apple to automate this functionality. If your phone is disconnected, your cellular is turned on. And visa versa.I have found on both my Ultras that having cellular turned on, even when connected to phone, eats up more battery than when cellular is off.

Are you using the apps a lot especially the fitness app? I also have the 5 and I find if I use my fitness app more than 40 minutes I only get about 10 to 12 hours out of it for the day. My Battery Health is setting at 75%. I did just order a new SS9 and trading in my 5. I find using the apps uses up battery as well as the day I set up my new 15pm and paring it to the new phone it used up 100% of the battery in about 10 hours. Since that day a week ago it has been a lot better.¾ of a day if im lucky.
You're the second or third person to point this out recently, and I'm now following the same practice. It never dawned on me that the cellular chip would draw power even when you're not using cellular.

The Ultra 2 is better for sure because it is based on the same chip that M2 is derived from.
The chip inside the Ultra 1 is much less energy efficient as it is still on 7nm and the high-efficiency cores are nowhere on the same level as M2 / A15.
It is why avoided the Ultra 1 as it had a super old chip inside (same one in the Series 6).
Is that with cellular and AOD on?I’m sure the U1 was similar, but the battery in the U2 is crazy. Put on at 100% in the morning, do an hour workout, use it throughout the day at work, use it throughout the evening, wear it all night for sleep tracking, wake up, work out again, and it’s still at over 60%. And that’s with display brightness set to full that whole time.
Yes, it’s a thick boi compared to my 45mm stainless, and the battery is only like a week old, but still amazing.
AOD on. Cellular is also on but that doesn't actually draw any power until the watch loses Bluetooth and wifi (which hasn't happened since the watch was delivered).Is that with cellular and AOD on?
Currently at 20% battery, an elapsed time of 60 hours.“Last charged to 100% Sat 10:47pm”
Currently at 51% battery, an elapsed time of almost 39hrs.

Exactly. Why would it not shut off cellular radio if iPhone is close by? This should be an option at least.Hmm. I wouldn't expect the watch to use any power for cellular unless you are away from your iPhone and a known WiFi hotspot. I'll have to turn mine off and see if it makes a difference.
That is incorrect. If Watch cellular didn’t use any power when it’s connected to your phone, then Apple would not have put a software switch in the control center to manually turn it on and off. Even when connected to your phone with cellular turned on, on the Apple Watch, the Apple Watch consumes more power because it is waiting for the phone to disconnect so it can turn on and connect to cellular.Exactly.

Huh? They have the switch so you can turn off the cellular when disconnected from the phone and WiFi. Why would it use power waiting to be used? That doesn't make any sense. I did turn it off for several days and didn't notice any difference in battery life. Apple says that in low power mode, cellular only turns off when your iPhone isn't nearby. (Also turns off WiFi).That is incorrect.

Turning off this feature will save power on the watch.
