Ultra Battery life

I did a full charge Friday night.

Start Saturday 5am with 100%.

30 minute walk in the morning, on cellular with AirPods.

50 minute run in the evening, on cellular with AirPods.

9pm it was at 30%. Wore it to sleep, woke up with 21%.

So 24 hour span took ~80% of the battery.

To be honest, I was expecting a bit more, given MKBHD's review where he did a 48 hour stretch, including wearing it to sleep twice, and doing 6 hours worth of workouts and finished with 20%.

But also - I would never have gotten this heavy of a day out of any prior watch, especially with cellular usage. On a given day, when running / walking while on cellular, I would absolutely need to top up the battery during the day. And even without cellular, I'd finish a 15-16 hour day with near 0 battery left (on my 10 month old Series 7).

Summary: was expecting a bit more, but given I charge at night anyway, I love the fact that I can go through a very heavy day of use without even needing to think about battery.

Early report so no good data but I set mine up Friday 23 (yesterday as of this writing) and it came with almost 90% ootb. Once setup (think it was down 10% to 80% or so after setup) I charged it to 100% and put it on. This was at 17:06 according battery settings.

It's been almost 23h as of writing this and I'm at 60%.

Of course, been using it more since it's a new device so there's that. Other usage points - went for a 1h walk logged as workout yesterday eve and I also use Autosleep so always sleep with it. I use always on display in the lowest brightness setting (there's only 3). Sufficient for Scandinavia right now and will be for 8 more months, hehe. When in dim mode I've disabled the compass complication on the Wayfinder face so hopefully it uses that sensor a bit less.

In sum, looking great so far and miles ahead of any other AW I've had (came from S6 and had S4 earlier).

Update: now at 20% and haven't charged yet. Time is 15ish Sunday as of this writing which is 46 hours since full charge.

Since yesterday's post I've done around 2 hours of workouts. Also slept with the watch and use always on display even when sleeping.

Looking good and means 48hours of life should be no problem 👍 I'm going to try and squeeze in another workout before charging and leaving for tonights adventures.

I was seeing about 1.5-2x better battery life. Today I wanted to try it on my typical Sunday run. Just finished a 4 mile run and a 1.5 mile walk while listening to a podcast (cellular on) with the Ultra.

Battery was around 80% and on my S7 it would be around 65%. Def better but nothing life altering.

I've had a good experience so far. I charged it fully Friday evening just before bed, woke up at around 93%. My Series 4 was usually using 12-15% during the night tracking.
Then went for a one hour workout early PM (just regular gym stuff), it is now close to 4 PM where I live and I'm at 77%. At this rate I'll only have to charge it again tomorrow afternoon, tomorrow evening. And as other pointed out I except things to get a bit better when several days will have passed after the initial setup.

I'm now at 37 hours since it was last charged, and I have 23% of battery left. Not bad at all. Especially if things get better after a few days/week. Anyhow, I won't wait until it is completely depleted before charging it again. Batteries usually don't like that.
 
9 hours in and got 82% left. so even better than yesterday so far. really challenge will be with workouts and how much it takes when outside in high brightness.

About 30 hours in.
-AOD on
-No cellular.
-1mi run yesterday
-1mi walk yesterday
-10mi run this morning (used about 16%)

Pretty impressive. With future updates I assume it will only improve.

For battery woes

1st wait 24 hours before worrying

2nd, after 24 hours if the total charge time, 100% to 20%, is bad then erase and set up the Watch as a new one. Remove unwanted apps in the Watch app.

These batteries discharge differently at high, mid and low values. This will alarm you, don’t give it much weight. Go by daily values. 100-60% day 1, 59-20% day 2 etc….

It’s currently Sunday. I put the watch on Friday night and didn’t take it off since (aside from changing band). Did a 2.5 hour workout Saturday.

Currently at 46% battery after about 36 hours of use. I don’t workout Sunday’s but I average 2.5 hours all other days. With activity i see this lasting 2 days which I’m happy with.

Doing a baseline (no activities or apps use) to see how long it lasts. Off the charger Friday noon - it’s now 11am Sunday and showing 54%. Should make it to Tuesday.

No one on here seems to be noting whether or not they have background app refresh enabled in their settings. What are most of you doing with that?

I got my watch yesterday at about 3:30pm and it was 90% out of the box. I set it up as new and got it to where I wanted it to be but kept the background app refresh setting turned on for all apps. I was down to 71% within a couple of hours. I also have AOD turned on and screen brightness set to the middle setting.

I turned off background app refresh for all apps but left all other settings the same and since then I went from the 71% at about 6:00pm to now (7:53am) at 60% and I had sleep tracking enabled.

Update: down to 11% after another 1h+ workout this afternoon. Charging now after 47.5h and safe to say it would have lasted more than 48h.

Got cellular enabled btw but my iphone has been close all the time so no pure cellular use.

Happy so far and will be interesting to see what the upcoming power save feature will bring. ⌚️⚡️
 
Currently 42h with 27% left!

Charged to 100% at 11 pm on Friday. Slept with it
Saturday 2:30h bike ride with low power and Polar H10 chest strap
Went to bed with around 60-65%
Today 2h hike with Low power mode

Now 5 pm with 27%. Except workouts and at night AOD was on.

Can go 48h easily
 
So today from 100% to 76% on a walking workout, 1:40 h, streaming cellular to an AirPods Pro, always on display activated and under the direct sunlight. Very good. Usually the Series 6/7 that I had would end it at 50 % or so.

UPDATE:

Charged to 100% at 2:15pm Friday. Not using any cellular.

75 min workout Friday Night
60min workout Sat AM
9km run - Sunday
All paired with Polar OH1 HR monitor via bluetooth

2km outdoor walk with GPS and 2km run with GPS Sat afternoon.

Watch was used for sleep for 2 nights now ( Fri and Sat)

48 hours now and Im at 26%.

I have not charged the watch at all. Usually would charge while showering. So based on that, I think 2.5 days should be doable.

took it off the charger at 100% ~ 5:30am yesterday, 2 workouts of ~ 70min each, I wore it overnight with "Sleep" turned on, and right now, ~32hrs in, I'm at 43%. I am quite happy with that
 
I got my watch yesterday, it was at 90% charge and I haven't charged it since. It's been around 24 hours since Turned the watch one and i still have 47%. This includes 2 workouts.

Close to 38 hours currently and at 9%. About 4 hours of working out over the last two days but only 25 minutes or so of cellular. The 25 minutes working out on cellular dropped it from 13% to 9%. Estimate I would hit 40 hours or very close to it. Used it exactly as I would normally which I would estimate as moderate use. Every battery seems to be a little different but for me the 36 hours was conservative.

Yes, 36 hours is very conservative. Perhaps if you use a great deal of functions it will only last 36 hours.

I am at 37 hours now and my battery is at 56%. Still using it off the first charge starting Saturday at 7am. I'm hoping the battery will last three days which it's on pace to do.
 
Charged it I’d day yesterday, woke up at 96%. 3 hours diving (in dive mode) and 2 hours in the pool. I put it on the charger at 37%. I’m happy with the battery.
 
Just started the first charge from a 100% at 8AM. 12 hours use with AOD took 17%. I will report back at 24 bourse and 36 hours, I am at 83%. Will be sleep tracking as well.
 
Ok. Here is mine after first full charge. After 47 hours it is down to 13%. AOD is always on except for sleep when it goes to sleep mode. This includes one bike ride of 40 min with iPhone nearby and heart rate on, pool session of about 2-3 hours without iPhone and on cellular while constantly playing with Depth app (its very cool and accurate while diving to 6ft which is max depth in my pool). So easy 48+ hours with some limited workout and little bit of cellular. One interesting thing is that while Depth app is on the calls or notifications do not come through and I couldn’t make a call. Once I got out of depth app everything worked fine.
 
I wore my ultra nonstop for 48 hours. From 1pm Friday until 1pm Sunday before it finally died. I slept with it on both nights. No workouts, but a lot of running around and standing on Saturday. Cellular wasn’t activated. AOD on. I basically never took it off my wrist.

To me, the battery life is fantastic. Especially since I’m coming from a series 4. There were moments when I “forgot” about the watch. Today when I finally had to charge it I had to take a second to remember where I put my charger.

48 hours in - I'm happy. 5 hours outdoor activity recording this weekend. worn all other times except when showering. Using cellular streaming Apple Music when at the gym each day.

Normally I'll charge it every day when I jump on my trainer for an hour but just wanted to see how this would do over the weekend.

See you all again when they release that ultra low power mode and we test that out lol
