I unplugged the phone and got onto the bus. I read news with Captivate. Nothing fancy, just NY Times, Fox News etc. I got off the bus later, I only have 73% battery.
Yes, I just started my day and it's only 70% of battery.
#FAIL.
There are a few simple things you can do to increase battery life. Turn the screen brightness down and use a solid black background as a wallpaper. The screen uses the majority of the batter. so dimming the screen helps, when using a black background the amoled display does not light up black pixels so there is power drain.
I've been running on the same charge since 4pm yesterday. I've streamed music through pandora for about an hour while exercising, browsed the xda forums using the XDA App for 30 mins, made a few calls, browsed Facebook for 30 mins, surfed the web for a couple of hours before bed. Its now 10AM and I'm sitting at 36%. Not to bad really! The phone functions exactly the same at 36% as compared to 100%.
I wonder why everyone says to use a solid black background? Do most people use their phones primarily by staring at the home screen? I'm never at my home screen more than perhaps five seconds while switching apps
I've had pretty poor battery life as well, even after discharging, recharging, and deleting batterystats.bin. There are small tips here and there, like black background and screen brightness, but even following them all, my phone lasts me barely ten hours, and most of that time it's idle. For instance, I listened to local must (no streaming) with the screen off for about an hour and lost 10% of my battery life. What's up with that?

I am also shocked and confused by how people can use their phone so heavily.
I already killed those unnecessary processes (e.g., all AT&T crap). I have a static wallpaper. I have screen brightness at 60%. And all I have been doing is just reading news and surfing the web. It literally cost me 1% of battery for every 1 min of use. It's just ridiculous.
You are probably on your home screen a lot more than you realize.
Anyway it's a smartphone, they all eat through battery time. you will never get superb battery life unless you crowbar a 3000mah battery into your device.
edit:
set the screen on its lowest brightness setting, the only time I've had to increase the brightness is when I am outside in the sun.
if you are on a bus, if you are not using wifi, turn off the radio.

You just said your phone is at 36% eighteen hours after charging! Compared to the 0% I'm at ten hours after charging...I'm not looking for superb battery life at all, just somewhat decent. I'm actually bringing a backup feature phone with me to college this semester in case I can't resolve this issue, because I will need to use my phone both in the morning and at night some days

I have Wifi, BT always off. And I don't listen to Pandora.
I think the key is you have the lowest brightness on your phone. It is going to save you a lot of battery 'cause half of the battery is for the screen.
But I just couldn't stand it. I wish I can set to 100% all the time. It looks so much better.
The phone radio is a huge consumer of battery - especially in weak signal areas. The bars are not that accurate either. that coupled with 3rd party apps that don't always behave nice, can equal rapid battery drain.
Putting the plain in Airplane mode is good way to see what battery life is like without the Cell radio always doing its thing. It is not a fix, but it can show that the battery/phone are not broken. There probably can be improvements and tweaks made by samsung, but I don't think the phones are defective.

This is what you would call a trade-off I like the bright screen also but I like having longer battery life more.
The screen is still pretty bright on it lowest setting and you gt used to the lower brightness after a while.

how are you using your phone? What apps are you running, are you using any emulators.
There's an app called Spare Parts, which will show you what is using your battery when the screen is off. Open it up and choose "Partial Wake Usage" from the drop down to see.
My Captivate appeared to drain battery very quickly, but with moderate to decent usage throughout a day I was trying to kill the battery it lasted me over 13 hours. I think it's a matter of the battery reporting taking a good while to calibrate properly.
I've had an issue twice now with absurd battery usage. Both times I charged the phone to full and disconnected it; after doing that the phone would lose 10% charge every hour sitting completely idle! Using the phone during that time drained it even faster. Both times powering the phone completely off and back on resolved the issue.

In AMOLED, black pixels dont use power. This is different from LCD where even black pixels still use power.
Have you guys tried fully charging, then fully discharing then repeating this step 3 more times? It helps with the battery life tremendously.
You gotta do a factory reset. Many people as well as myself had the same issue. For me, a side effect was also that the att start up swoosh was stupidly loud.

I only did the discharge thing once, last week, and today I am going on a 21 hours with 28% left.
2g app
I was told there is a 2g / 3g application. Has anyone tried this? Apparently it puts the phone in 2g when no data connection is needed and then updates to 3g when a data process is required...
i'm on day two of not charging mine... and i'm at 25%...
i unplugged it from a full charge yesterday (monday) morning before i left for work and today (29 hours later) i'm at 25%... this is with advanced task killer auto killing tasks when screen is off as well as being aggressive about it. i've been listening to music from my sd card, browsing facebook and taking some pictures (and uploading them to fb). i guess i'm either super lucky not to have any problems with GPS or the battery, or i'm a very light user.
I dunno what happened to the main battery thread?
I just got a new phone two days ago because of the restart issue. This one has the same battery issue. Drains 2-4%/hour just being idle. I have nothing beyond launcher pro and google voice installed. Everything is on lockdown in terms of batt usage. The only thing I haven't done is turn off the cell antenna.
I've tried the tricks I knew: factory reset, calibration trick. These didn't help at all. My last phone just needed a factory reset and it was all good. Now I'm sad again :-( will it just improve itself when the phone "learns" the battery or something? I wish I could teach it
Several things you can do.
1) Use WiFi if you can use it, it uses less power. If you don't have somewhere to use WiFi, leave it off.
2) Same goes for BT- leave it off if possible.
3) Use this to get rooted and remove all the ATT crap that sucks battery life. Applying the lag fix also means you spend less time with the screen on, so that can also help you out.
4) Use Auto Brightness
5) Disabling haptic feedback and the tapping sounds (I find it more annoying regardless)
6) Use a static black wallpaper- or something really dark. IMO it looks great black and plus the AMOLED... Black doesn't use power.
7) Use Advanced Task Killer. I have mine on Aggressive and Moderate security every half hour. This will make sure hung apps, etc get killed and apps you haven't ran. Make sure you whitelist the apps that run your widgets and such though.
That's the best things to do to.
Edit- above all, remember this is a SMART phone, not a feature phone like the iPhone is. The simple fact this full blown SMART phone can even begin to rival just a feature phone like the iPhone speaks volumes to how much more efficient it is than what you think it is.

I too have had issues with battery life but quickly realized what had been causing the issues, twice it had been snesoid not closing down all the way after use, and this combined with an app that was hurting battery life (word feud), I realized what my problem was.
I leave the brightness jacked all the way down. I believe the lowest it goes on the stock rom is like 15%, but there are ways to go lower than that.
I've not used my phone much the past two days since charging it, and i'm currently down to 35%, but most of my battery use is cell standby, with display being 3rd or so on the list.
You can always use a program like tasker to make the phone go into airport mode between certain hours of the day (IE: while you're sleeping) to help conserve the battery life.
There are also tons of other good tips in this thread.
And trust me, the phone can last; i've managed 3days on one charge
I've heard in multiple ROM threads that you basically can only get four hours of screen display out of the captivate battery. The concept is that the screen is the single largest drain on our battery. I'm not sure that's the case, as the following screen caps show.
The first pair was run a couple days ago (wifi and data off). I charged the captivate to full, and turned the screen on permanently, set the screen filter program to 25% (darkens the screen - supposedly saves battery), ran "Desk Home", and went to sleep. I woke up, and the battery still was not drained. In the end, I was able to minimize usage until 11am or so, and took screen shots before the battery drained completely, and ended with over 12 hours of screen display on 80% of the battery (and some trivial usage).
To see if it was the screen filter program was the cause, I repeated this last night. This time, I didn't run desk home, but just turned the lit up phone upside down. Again, there was still significant battery when I woke up. I had to turn the screen off at 9am (as I was going to be away from the phone), and checked back and screen captured at 11am again. In the undimmed (but lowest brightness setting), I got 9 1/2 hours of display usage on somewhat less than 80% of the battery.
Conclusions I draw are that the screen filter program does extend the life of the battery a small amount - say, 7% per hour vs. 8% per hour with no external dimming program. In the past, I've had similar results playing games or reading ebooks (about 8-10% per hour usage). But it seems obvious that 4 hours of indoor (lowest brightness) screen display on my captivate should only be using a third of the power. Where is the rest going, and why doesn't the battery usage display show what is really drawing down the power?
I have my theories - all related to the modem functions: connecting to the data network, connecting to wifi, and connecting to cell phone towers. Perhaps when I have time to move some massive file across a good wifi connection, I'll see what kind of battery drainage that gives me.
This is on Continuum 6 RC1 with the JVQ modem and talon 0.3.1 - 1400, for reference.
Huh ? who comes up with stupid myths or why would you even believe that when review sites like gsmarena did a review and they tested media playback they got 7:25 hours of media playback with screen at 50%.
Alot of things can drain battery radio , cpu , screen.
Ya I have to agree. It is meaningless when like you did you turned brightness down l left screen on doing nothing. It in no way tests actual usage
Sent from my GT-I9000 using XDA App
The 4 hour limit is one I've hit on ever rom since 2.1. It is not based on the phone/cpu sitting idle. It's based on actual usage (browsing the internet, playing games, texting, etc.). When you are actually using it the cpu clock ramps up and that along with the display being on is what eats the battery.

Criminy. First of all, the "four hour limit" is mentioned in multiple ROM threads, as well as by nybmx in the post above. So I'm surprised that you are inferring this is new to you.
And if you try a little reading comprehension, you'll see that I specifically tested this out because I didn't believe it.
I hadn't heard of a 7 hour test. I've heard of some roms lasting 5 hours or so, running a single task. Which, in theory, could be consistent with a "four hour display life" and a days worth of other stuff - random calls, messages, etc.

Which, coincidentally, is how the conclusion I came up with at the end of my post. Except for the CPU. In normal phone usage (for me at least), the CPU isn't under constant strain. Does anyone have actual data about what the CPU is doing under typical tasks, like talking on the phone or listening to music? I have looked at CPU usage with the GPS test program in Froyo, and the cpu usage was always at 100 and 200 Mhz (i.e. not topped out at 1 Ghz, or more if OC'd).

It's called the scientific method. You test each variable separately. If you know how much power the display draws per hour of use, and how much the phone draws, and how much wifi draws, etc. you should be able to figure out what kind of use you will get in any scenario.
Do you know how much battery is used when GPS tracking alone? If you don't, then you won't know if you can track constantly during a 6 hour hike or whether that will drain the whole battery. I do, because I've tested it separately. If you gave me a scenario where you said I would track GPS while listening to music, and checking my position occasionally (say an hour of screen time) over the course of four hours, I'd be able to give you a pretty good idea of what my remaining battery will be, because I've tested those variables multiple times. On my phone, that scenario would drain the phone about 64%. [I imagine I'd give it a plus or minus of 8%].
For my money, that's "actual usage". If you are trying to figure out battery drain without controlling conditions, you'll never have accurate information.

First of all, thanks for confirming to ghost77 that such a limit is "known".
Reread my post. I think it's clear that I'm not saying that I think the 4-hour limit is based on an idle phone. The point I hope I'm making (explicitly in the 3rd to last paragraph) is that, even though "the cpu clock ramps up" and is used in whatever program you are using, the battery monitor is reporting that it is the display that is using the battery. It does not seem to credit the program (messaging, phone, internet, game, etc.) with the boost in CPU needed to do whatever you are doing.
After all, if we can all agree that the display uses 8-10% of the battery per hour, then having the display on while idle or when displaying a web page shouldn't make a difference to how much energy the display is using. In reality, if your phone is good for 5 hours of surfing, it's not the shiny display that has drained your battery, it is the transfer of data and rendering of the data as you manipulate the pages - all usages that should be credited to your internet program, not your display.
And if I've got you to agree that far, then it's a short step to reiterate what we've both said - it's the actual usage on the phone, not the display time, because the phones are more than capable of more than four hours of display. In which case, the four hour display limit is really unrelated to the display, but is a proxy for how much time you've spent using your phone for other stuff.
And then we can agree that you can get maybe eight hours of doing something simple like using a book reader program like Aldiko.
And then maybe you can see why I called the four hour limit a myth.
It's not a myth... Your taking a statement out of context. And wasting a lot of white space in the process.

Actually it might, depending on the colors the screen has to show.
It's a well know fact that for OLED screens showing white uses up a lot more power then any other color. Most articles even say that showing white is the one area that LCD screens end up using less. Unless the screen actually contains white OLEDs (which ours does not, but whatever comes after the SuperAMOLED+ most likely will)
A second way that color matters is that for our SuperAMOLED screens the number and size of the green OLEDs is different then the blue/red. Without the specs on them no one can say just how much electricity is being used, but it is a factor.
Also, I recall reading that red LED/OLED use the least amount of electricity then any other color (given that all other details of comparison are equal) So there may very well be a difference between a screen that is using mainly red then blue, even tho they are the same in size and number.
Since the vast majority of web sites are a white background and black text, or a similar bright screen and dark txt, they are gonna use up a good deal of power (in comparison to any showing any other screens). This is also why there are no white, light gray or other such bright themes made for our phone.
I'm pretty sure that "Screen" includes the Display, multi-touch sensors, tilt sensors, GPS, compass, and all other sensors/input devices.
Hey, this is to anyone, but i saw Soccer_dad's graphs/ battery usage, and I noticed my battery stats dont reset when i plug in to charge and unplug. Even if i reboot my phone it still keeps past charges and discharges. Right now it says my phone has been on battery for 4 Days and 7 hours, when clearly Ive been charging every night. Is this a bug?

Looks like TasKilla is abusing it's launch on startup power. You should remove that app. No app should be using that much over a 4 day period unless you had it running for that long.
Yes it's a bug.
Four hours of use is not the same as four hours of screen time.

out of a total of 11 hours of processor usage. Just sayin... As a rule of thumb, good android software spends 99% of it's time dormant. That thing is using more processor then it should.
Is it normal to immediately get to the 99% of your battery just after you have the notification your battery is fully charged? Well not immediately, like in a minute, more or less.
And how long does your battery last? Video-wise, it lasts great, but even with low-end games seems to be such a drain even on the lowest brightness setting.
mine also
I don't know if it is normal or not, but mine does this also. Mine immediately goes to 99 percent after being unplugged.
Don't think it's a problem. Remember, you're relying on a sensor in the tabby to give you a percentage; who knows how accurate it is? I'd be much more concerned if the battery was being expended too fast after normal use.
Face it, some battery sensors are just lazy dicks.
G.B. Says
And remember, talking dogs are liars.
I think is philosophically right. Any little thing you use is not 100‰ anymore.
But as that guy before me said, there is the sensor issue and on top of that the variables that my affect the very way the battery work.

i would say totally normal.
I would say the more important question is, How long does your battery last overall?, and not just from 100% to 99%.
At 17% I managed to watch America's Got Talent which was 1:25:++ on Auto Brightness in a dark room. As I said video-wise, the battery is great. But using it even on just simple document opening, the 90 - 100% mark seems to drain off pretty quick?
Can anyone tell me your battery stats? Even for a specific game with your settings(wifi on, auto brightness or lowest brightness, etc.). How long can you really go with this tablet on a pure gaming use? I really want to know. My old Android phone was not a battery beast or something so I understand, but this has quite the battery so I just want to make sure. Thanks.
Edit: Played Stardom for 3 hours at minimal brightness(like 5%). Everything is turned off(wifi, bluetooth, gps and etc.) took about 30% of battery. Seems legit. And by the way I have the 6200 so I have a network coverage. Anyone can compare with theirs?
Hi,
I'm trying to figure out what options would keep my battery life up on the s2 3g.
I've had the watch for a couple days now and I'm trying to figure out which features drain the most battery.
I would like to keep 3g on (but it's not really necessary when sitting at my desk all day), bluetooth, and always on. I don't mind keeping the screen at a brightness of 3, and my watch face is a dark background, I have 6 apps selected for notifications.
I do not have gps, or wifi on.
I guess what would be helpful is basically a list of the most battery draining items on the watch. It would also be great to have a battery management app (for the developers out there) that could quickly turn on/off certain items. Right now there's a battery saving mode, a do not disturb mode, and airplane mode... these are all in different locations, but I guess it wouldn't hurt to have some more quick control over all these types of items and additional ones to just manage all the battery draining items, like the pedometer and other "ometers"... is there a way to turn those items off?
Overall I love the watch, but it would be nice to not be thinking about the battery so much... and just use it.
I'm wondering the same thing. Turned it on at around 6am, have brightness set to 1. Haven't used it that much. Wake up gesture is on but not screen always on. I'm at 30% at 2:41pm....with my gear s I was able to get through a 6am-9/10pm day on auto brightness and still have a little battery left (that included a 2 mile walk in the morning using some health exercise with gear s.) I haven't even used the exercise option in this (other than the pedometer) because I'm afraid it will drain the battery.
I love everything else about the s2 though
I'm suppose to get mine this week and battery is my biggest concern. I plan to use this to run for up to 2.5 hours and play mp3's. I might cancel based on what you 2 are saying.
I do have nfc on, 3g on auto switch, and WiFi set to on (only switches on if I walk out of bt range) I did get a lot of espn notifications, texts, email...but not any more than I did on the gear S. I have the screen set to stay dark and not turn on for notifications. With my gear S I had the screen set to turn on full screen with every notification. I'm going to try tomorrow with nfc, 3g, and WiFi off....but, I shouldn't have to do that...I should be able to use all those, if needed, and still be able to get the 14-16 hours+ that I was getting with my Gear S. Like I said, I do really love everything else about it!
Try a restart
I had a terrible first day, with the Watch dying after 8 hours. I suspected that some of the app installs were having and draining it so I restarted both phone and watch.. The next day, I got 15 hours and still had 40 percent left. I have NFC and wifi turned off, network to autoswitch (with me leaving phone home and relying on 3g for 2 hours), turned off "always on" screen (because the wake gesture is SO much more accurate than with Gear S), and a white watchfacer with brightness set to 7. Very happy so far. Suggest restarting watch and phone after Gear app installs or updates
Thanks! I'll try that. Is your location/gps set to off? I also had s voice set to a voice commands and have now turned that off. Is a white watchface or black more draining? (I would assume white would drain the battery more)
I think the NFC, GPS, Always on being turned off have been a huge help with the battery life, and I understand why those things would drain a battery, but it would be nice to be able to have everything turned on and at least get a day's use.
In general I assume the first day you get the watch it his heavily impacted by the app downloads... I let it drain to zero and then fully to 100%... I also stopped playing with it every ten seconds. BUT as I mentioned earlier, this should be usable for a day minimum with normal usage. If Samsung has a "normal" usage setting in mind that will allow for a day (or the 2 days advertised for the 3g version), there should literally be an option in settings called "normal usage" that should get you the 2 days.

I absolutely agree! I was able to get 14-16 hour day (with some left) on my gear s, with all the options that I wanted turned on. This this new and improved device should, at a minimum, give me comparable battery life! I'm also having an issue with the activity tracker telling me I'm doing light activity when I'm sitting on the couch watching TV....that is definitely not light activity.

Yea, we'll see what happens with future updates. One of the big draws to this watch (aside from all the other enticing factors) was the battery life... I guess time will tell.

Was also curious about everyones setup.
First 2 days i didnt take into account battery because i was playing with it alot.
Today, booted watch at 7am, booted, got on, checked in 15 minutes, and was from 100-69%
Current setup,
display at 3%
about 10 apps that alert,
S Health
3G/4G is at auto
GPS-off
NFC-off
WiFi-off
i did have a Power Ranger face(which i loved) but it had alot livewallpaper action, blinking lights, and pieces that moved etc, changed to the default one with the stars in background with digial.
i am currently at 33% from 7 1/2 hours of usage
no music, have not taken any calls, havent responded to any messages, literally looked and swiped away.
Would a rooted Sam N4 have any effect on the performance of the watch?
I was on stock, but was horrible after the lolipop update.
Still on stock ROM, just rooted and bloatware removed, nothing special.
Ok, good thing there is a thread on this already.
So first day I didn't take battery into consideration, because you always fiddle with it too much. Then I had to work for two days, and my job is heavy construction, so I don't bring my watch, I left it on the charger for two days straight. I put it on Friday night, and didn't charge it till Saturday night. Today (Sunday) I was at 15% by about 12pm, and I took it out of the charger by 9am. This doesn't seem right. Did leaving it on the charger for too long mess up my battery? What is going on here?

Were you on just 3g...instead of bt? My battery life has improved with turning a lot of the options (wifi, nfc, heartrate monitoring) off. If I'm on 3g it is a whole different story....accidentally left my phone home the other night and was remotely connected between watch and phone....dropped down 40% in less than two hours. Has anyone else had a similar issue?
I don't have the 3g model, I have the classic. Yesterday it was good for the whole day, but to be honest I didn't check the battery when I took it off the charger this morning. I went to bed at 2am,so maybe between 2 am and 9 am it didn't have time to fully charge?

I think the variant of the 3g gear s2 and your network is key for battery life.
I have a tmobile carrier gear s2 and the battery life for the first two days was at about 18 hours off the charger each day and ending up with 15% at the end of each day before charging.
Mind you this is with 3 email accounts getting maybe 10 emails per hour, Answering texts and even taking a call or two on the watch, and also controlling my spotify for my note.
The tmobile watch has auto on/off 3g for when you disconnect from bluetooth or WiFi to your phone. I've heard that not all gear s2's have the auto on/off 3g feature?
Overall highly satisfied. But just turn off what you don't need when you don't use it has always been the name of the game when it comes to any mobile battery life. Nfc doesn't need to be on if you don't use samsung pay consistently. Neither does WiFi. Bluetooth and or 3g should be all anyone really every needs for true daily usage imo

I agree. I have had the 3g version since 2 days after its launch on T-Mobile. I had a white one and returned it b/c I was convinced something was wrong with the watch. I got a second one (black one) two weeks later and have the same issue. If I turn off all of the functions I wanted the watch for -- i.e., 3g, Wifi, NFC -- I can get a day of use. This is really disappointing b/c I have the classic as well, and it lasts twice as long with the same amount of activity. I hope Samsung does not something to extend the battery life on the 3g version.
I also have the Tmobile Gear S2 and on the first full day, I only got about 10 hours of battery life with very little use using all of the watch defaults. On day 2, I opted to turn off wifi and the cell radio and now I have great battery life. In excess of 17 hours if not more. On day 3 I decided to turn on wifi and bluetooth only. Battery life is still fantastic, once again in excess of 17 hours if not more. Next test will be all three radios on again, then just the cell radio only.
Hope this helps,

What are you guys doing with your watches that you need 3g and wifi on all the time? I have mine setup with bluetooth on and 3g auto with wifi, gps, and NFC turned off. I also have the heart rate monitor turned on and set to take my heart rate as often as it will. I have screen on all day and display is at 3. I can make it a full day (630a - 10p) and still have about 40% left. I basically use mine while at work to check notifications so I'm not constantly picking up my phone just to clear a twitter notification. I know they made it so that you can use these for content consumption, but I don't think it was ever meant to be it's primary function, that's what the $700 cell phone in my pocket or the 400 tablet in my backpack is for. That being said, if you wanted to use it for a run and listen to music, do it. Just know that you may need to throw it on the charger later on when you are relaxing on the couch. To me, a full days use on any device is fair, but that's just my 2c.
Since the Galaxy Watch 4 is not a champion when it comes to battery life, I'm sure we're many wanting at least 2 days battery life WITHOUT disabling all the features that made us bought the GW4 at the first place.
I can easily achieve 2 days battery life AOD Off, Wifi Off. All the other features is turned on.
I was wondering if turning on AOD and disabling Raise Wrist to wake would still grant me 2 days battery life since I heard that apparently RWTW consume a pretty good amount of battery every time we tilt our wrist.
How about you guys?
AOD off is a dealbreaker for me. Any watch that doesn't have real and usable AOD, I would not buy. So I would never turn off AOD (unless I was caught somewhere with a low battery condition). I leave raise to wake also on. I know these will suck battery, but that is how I insist on using the watch. To conserve other power, I turn off WiFi and NFC. Not much else I can do.
i don't really care about battery life that much, as long as I can get through a typical day. Charging once a day is fine with me. I have been doing it for many years with the Moto 360 1, Moto 360 2, and S3. I just hope it does wear out the battery too soon (as in, diminished capacity).

With that configuration how long does the watch stand approximately? Do you track sleep at night and with a workout routine does the watch still have battery left until the morning?

I must confess I've never really understood the need for AOD as long as the wrist gesture to wake works properly (which admittedly hasn't always been the case) - and I'll take the extra battery life with it off any day over any real or perceived inconvenience of turning your wrist to see the time.
I haven't yet been able to fully determine how well it works on the GW4, but on the Gear S3 it was perfectly fine, so I am expecting it to be at least as good.

In my case, I often look at my watch at times I don't want to perform an obvious gesture, like in a meeting, or in front of someone. I want to be able to look at the screen anytime, in any circumstance, like a "real" watch.
Also, just vanity, but.... I went to all the expense and fuss to get a classic-looking watch- round, silver, pretty, matching band, fancy classic watch face, to look like a "real" watch, and "real" watches have an always-on display. I have fooled many, many people over the many years, who had no idea I was wearing a smart watch.

That's fair enough.
AOD is a sure great feature but it has a pretty huge impact on the battery as opposed to what some saying that it only consume few % of battery. In my testing it consumed 20% every 6 hours, and i could definitely feel the difference AOD on and AOD off.
Since my daily routine include a workout session and since I use sleep tracking, I am afraid that my daily routine can't be compatibile with AOD. It's a annoying not to be able to use the watch to full capacity and having to make choice between fancy look and fitness.
Hope they will be able to improve battery life with updates...

It will vary a LOT depending on which watch face. Probably why most faces have light indicators on a dark background. Also, some faces have a much "simpler" mode when in dim/inactive mode. But yes, it will consume a lot of battery compared to AOD off, unless the dim/inactive mode is very simple and dim. But if it is too simple/dim, it might not even worth having AOD on.
Watchmaker has a feature which shows how many pixels are on with each face, both in active and standby mode. Can be useful. Plus you can edit the face to turn whatever part of the face you want off in dim/standby mode to help save power. The face I am using now, I turned off the logo, always, and the second hand and some of the background off in standby/dim mode.
