I know some here have turned off auto recognize workouts as well as raise to speak to Siri. Have you done that?
Yes I did that. I think it improved it a bit. I do get a lot of notifications and also track my heart rate regularly during the day, so I guess that also drains some battery. Coming from a S0, my battery life is great ;-)

Raise to speak has zero impact on battery.

Background app refresh seems to be a large drain but so is waiting for apps to update.

The biggest battery hitter is the heart rate monitor. Normal battery drain is between 1.6-2% per hour. A 1 hour workout can easily take 10% off.
 
The Heart Rate complication is a drainer, but almost all stock Apple app complications are not using a lot of energy.

I think another thing is the connected phone. Only the X and higher have Bluetooth 5, just as the series 4. I have not tested, but theoretically Bluetooth 5 is more energy efficient.

Actually Bluetooth 5 was introduced in the iPhone 8 alongside the X.
 
I am wondering if drain on my S4 w/ iPXs is the cellular contact time or watch trying to get back on WIFI since so close to house doing yardwork.


S4 Seems to fast drain during days with outdoor/watch only activity. Never the case with S3.

Today: down 61% in 10.5 hours, during which 3.5 hours in yard weeding. tiring but no exercise-level heart rate.

Think next time I will turn off WIFI, see what happens. already have reduced watch faces including modular variations, turned off walkie talking, extra alerts.
 
Turning off walkie talkie from available to
Off sorted my battery life issues
Walkie talkie availability also has zero impact on battery.

I have been testing what affects battery and this isn't one of them. Only actually using walkie talkie uses up battery.

Clearly that’s not true as it was the cause of my battery drain as it was consistently being used where the notifications dot was

Just because it wasn’t your reason doesn’t mean it’s not the cause for somebody else
 
First time AW owner here. One of my worries was the battery life, coming from a garmin Vivoactive hr that lasts more than a week on my wrist.
At first the battery was drawing fast, I deleted infograph faces, and did not use the heart rate complication.

But last night I decided to let the watch go to Red and then charge it.

So far today, where I would normally be at 50% I’m at 78%.

So maybe the watch and battery need to calibrate themselves.

Just my 2¢

I just picked up a 44mm Apple Watch yesterday morning when the Apple store opened... took it off the charger last night around 1 am and the battery seems to be draining faster than my 2 year old series 2. With the series 2, I could wear it all night and have 100% still when I woke up - this morning I was already down to 93% when I woke up. I’m at 4 hours used/16.5 hours stand by and 62%.

I am using the new info graphics watch face with activity rings, calendar, weather, weather conditions, wind speed, HeartWatch, battery, and monogram. I’ve left everything on except detect gym equipment as I never use gym equipment that can sync with the watch.

I finally got the 44mm space grey alloy LTE. The battery lasted from Saturday morning 11 am all the way to this morning 9 am. Running solely of LTE, not paired to my phone (off)

I have turned off quite a few options, but so far i am very content with the battery life knowing i can easily run of LTE only for at least 30 hours or more if needed (i will charge it daily anyway)

I will make some youtube videos about it later on.

Do you mean the stock apple Heart Rate complication? I have it on my watchface but was not thinking that it could drain the battery, because it should only activate when launching it?

Thats actually really good to wake up with 93%. The only way I've been able to get that is disable background app refresh but I refuse to turn my watch into a Casio.

Normal battery drain under light/sleep use should be around 1.6% per hour. Depending on which model you have.

Usual use during a day with movement is around 2-3% per hour.

Biggest drain on mine is the Carrot complication which updates every 30 minutes.
 
Second time in a row that I go to sleep with 100% and I wake up at 6am with the watch at 12%. This is insane to me. No idea what it could be.
 
On my S4 42mm LTE turning off WiFi seems to have made a difference to my battery life with my usage patterns.

Generally speaking I’ll be away from my phone for an hour or two every day, I think in my case turning off WiFi has helped as while I’m away from my phone it won’t be searching for a WiFi signal? Seems to make sense to me and appears to be working but I guess that could be some kind of placebo effect.

I normally end the day on 60% or above

I also think the poor battery life is related to wifi.

I wear my watch to bed and my phone is downstairs (charging), with the S3 I would lose somewhere between 6-12% overnight (theatre mode /do not disturb on), and the watch was connected via Bluetooth.

With the S4, I'm losing 30-40% !, the main difference is that for some reason the watch is WIFI connected not Bluetooth (phone in same position as previous).

I understand that it appears to be good compared to others on the thread, but it’s strange that my S2 never did this! Granted, at the end of the day, battery drainage seems to be the same. Maybe it will improve as it cycles a couple times - I’m hoping for that!

I think it’s the OS draining the battery and hope it will be fixed. I have a S4 now and get to about 50% each day. But I had an S3 and the battery life dropped dramatically after upgrading the os from 4 to 5. I honestly believe there will be an update that fixes battery life.

I am hoping it is a bug issue that can be fixed with the watch OS. I bought the series 4, non cellular, as well as the Nike cellular (one for my dad). Both are experiencing the same thing.

I notice the drain on 5.0.1, not before on S4.
 
I’m paying special attention to this thread as I’m on the fence about ordering the new series 4. Had the SSSB series 2 and got tired of the constant battery charging so I moved to the Garmin Fenix 5 ten months ago. I love the 14 day battery life but do miss the richer notifications and ability to reply on the Apple Watch.
 
My battery is far worse than my S3 was with the same usage pattern. That being said it's fine. I go to bed at 45-50% now instead of 70%. It still clears my days without any reason to even check the battery %, it just won't truck through a second if I needed it.

I believe The battery issue is software related and will get fixed. even so, wouldn't trade my AW S# for anything else.
 
A new version of iOS for iPhone is being released today and one of the things being fixed is an issue where Bluetooth could “become unavailable” - I wonder if this will help?
