I'm starting to see a correlation between absolute crap-for-crap batter life and having the ambient light detector enabled. I'll do a test tomorrow, but I'm pretty sure if I just left my screen on full brightness all day, that I wouldn't get as bad of battery life as I do with the ambient light detector turned on.
Is there a problem with the fascinate's polling period? or possibly how much power is being sent TO the sensor? This might explain the problems on hacked roms where people are noticing a buzzing/hissing noise coming from the phone right around the area of the ambient light sensor when in the middle of a call (and the screen is on).
Has anybody seen where in the code the ambient light sensor is handled? (is it in the kernel, or somewhere in the drivers?).
*EDIT*
Thanks for moving my post. I was pretty annoyed with myself for posting in the wrong section.
*edit* Now that the thread has been moved, This post could probably be deleted.
--------------
Well, since nobody has moved this to the other forum yet and it's received a few views, Has anybody else noticed this before?
My personal experience had been full brightness ate battery fast and low brightness was a combination of hard to read and similar drain to auto. Then again my phone has never hissed at me except for godawful noises using skype wifi sometimes, and I have never messed with brightness under froyo.
My only observation with froyo roms is that "stock" eb01 was awful but superclean and AOSP were pretty good, particularly under EB+ kernels.
Also, I lose more battery than I would like to from signal loss overnight, but turning off 3G seems to help with that.
Swyped grumpily from my advertised as "can be upgraded to Android 2.2" device.
i noticed that the automatic brightness setting is absolutely terrible at choosing the correct brightness.
the froyo roms added the ability to hold down on the status bar and move left and right to adjust the brightness, so i just use this to adjust it on the fly when necessary.
this doesn't really answer your question, but i figured i'd add my 2 cents

The noise comes from having the key backlights on during a call.
If you are referring to the softkeys, there were some assumptions that this was the case, but I have tested this out and have heard the noise even when those lights were turned off.
Also, I ran my phone at about half brightness today all day. I've had it off the charger for 15 hours, made 3 hours worth of phone calls, and it's still at 41% battery life.
2 days ago when I just had my phone in the pocket, not doing anything and leaving the screen off (with auto brightness enabled) my battery was dropping significantly after only 6 hours and no phone calls or Internet usage.

Hey xda,
I'm curious as to what you all use for your screen brightness settings. For the duration of my ownership of the fascinate, I've kept it at the lowest possible setting. I'm wondering if that's really doing that much for my battery life. I'm contemplating turning it to auto.
What do you guys think about screen brightness as it compares to battery life. Is the screen not lit with LEDs? If I'm not mistaken, a typical LED could run for like 40 years on a single AA battery.
I am on auto with GPS, Data, and sync on all time. I use it pretty heavily I would say. Nothing like hours at a time but 15 min here, 5 there, 10 there. I get about 16 - 18 hours out of my phone.

Thanks for the reply. I was wondering if I should keep GPS on too. I mean as long as I'm not actively using it for navigation, is it really going to be draining any battery life?

Adryn has stated "Keep GPS off" for better battery life. Idk if you are using SC tho, but this would apply to any.

I keep all but wifi on w/ brightness varying bc im outside a lot. Im seeing 24 hours minimum w jt's aosp w nextheme. I use my phone for everything.
If forget to leave the brightness up all d way, i notice a huge difference. These are a little different that an LED and a double A my friend.

Thanks for the response. So what you're saying is you leave the brightness high, but you know that's detrimental to your battery life?

Yep...but i'll sacrifice in favor of beauty for a loss of thirty min. Of use
how long an LED runs on a AA depends, some might run a day (not 40 years), others less than an hour, and the most powerful ones need multiple D batteries just to turn on. these phones have a SAMOLED screen, broken down into: Super Active Matrix Organic Light Emitting Diode. the important part here is the organic. instead of having a single, or a few LEDs behind or around the screen, the screen uses an organic (not organic like the meaningless buzzword, but no ****, it's organic cells) compound for each colour. these organic compounds produce light when electrically charged, and only when a colour is displayed. this gives you the possibility of a truly infinite contrast ratio, and brilliantly rich colours.
I leave mine on auto.
Was using the lowest setting, but I'm now using auto setting.
I normally have it at its lowest setting unless I'm outside. I used to have it on auto, but it didn't work exactly like I wanted. Now that the notification bar brightness feature was added with Froyo, I just use that to adjust the brightness without having to open up settings.
As long as you don't have the screen on for minutes at a time, the difference between automatic brightness and the lowest setting is minimal. I switch to automatic for days that I tend to be outside a lot, but I normally leave it on the lowest setting because I occasionally go on binges where I read the news when I'm bored. If I don't do that too much and don't have any phone calls that last over 15+ minutes then I get about 48 hours of battery life on JT's AOSP ROM.

I have ongoing problems with eyestrain. Back-lit screens seem to be the issue. Have you found the SGS2 better or worse in regard to eyestrain, if this is an issue for you. I would really like the SGS2, but I may go with the Sensation if its screen may be better for me. Is max brightness on the SGS2 bearable? Reducing brightness seems to increase flicker on LED screens.
Does the job very nicely,
https://market.android.com/details?id=com.haxor&hl=en
Regards.
Is it possible to keep SGS2 brightness at max and then use this app on top to make it appear darker? Or is Screen Filter just a replacement for the SGS2 brightness control that allows further dimming than minimum, or does it work differently?
Thanks
I havent noticed flicker on the S2's screen on normal usage unless I open up specific test patterns for flickering like this site
http://www.techmind.org/lcd/
It of course is to dimming it over min brightness for easier night reading without any sort of strain, haven't used with Max brightness as even 25% is too bright for me for normal usage and then that app with Auto brightness for night readings/browsing
Regards.

Oh. I thought maybe it worked differently since on the app description it talks about applying a "shade" over the screen.
It might work for me if it did not actually dim the LED, but "filtered" the information to be displayed so that it came out less bright. I don't know how exactly that would work, and I guess if this "software" dimming was available then manufacturers would already be using it.
I've decided to go with the HTC Sensation. I figure that the SGS2 will either be the worst or the best phone in regards to eye strain, and it's not worth the risk. Kind of bummed out since I had my heart set on the SGS2 but hey everyone keeps saying that they're both great phones.
Both phone are great but i dont seem to experience eye strain on sgs2 seems good to me...imho
The screen dims and changes brightness by itself so much I am contemplating just turning it up and leaving it.
Any thoughts to this, and does it drain your battery super quick?
Seems a waste of the SLCD 2 to have so dim and changing brightness all the time

If you plan on disabling brightness just keep in mind if your an outdoors user or indoors user, the lighting around you will play a key roll on what levels of lighting you decide to have.
Personally I have the Automatic setting enabled, but I keep a widget (via widgetsoid) handy so I can disable it when I want and how I want on the fly.

Max brightness will definitely have an adverse effect on batt life. I personally keep mine at about 40% which is fine except when im in direct sunlight.

I know what you mean, I tried doing the same because I got sick of the brightness changes all the time, but after a couple of days having to adjust it myself or compromise on batt life, I decided to go back to Automatic settings... In my life I go to much outdoors as I can spend hole days indoors its what ever happens, happens so I decided to stick with the annoying setting other than being annoyed by having to set it myself.
Screen brightness is the biggest contributor to battery drain. I keep mine as dim as possible at all times. I've unfortunately become quite OCD about it.

I'm the same way. But the problem I have with this phone is that the more dimmer I make it, the more uglier the whites become (which I have become OCD about).
So I have double OCD working against each other and my brain is going to explode. That is all. Carry on.
Ok; the phone has been out a few months. Anyone's opinions changed?
I generally keep screen auto-brightness OFF, and set it to about 60% to 70% brightness static. When plugged into power to watch video, I go to 100%.

+1 for Auto and a widget. Most of my use happens at the extremes - OFF or 100%, so this provides easy switching.
I keep mine down around 10%, and only use autobrightness when outdoors
Though I feel Brightness setting 1 (presumably the lowest brightness setting) is too bright, the Auto setting is a drasticly lower brightness level over all, washing out the sharpness and vibrancy of the display in both ambient on and ambient off modes. It seems a shame to have to settle for the flat tire watch face when the overall effect of the light sensor living in that area does not seem to provide a worthy purpose.

I just purchased this watch and was wondering that same thing. It's too early to come to a conclusion as I've literally only had it for a few hours. I'm going to try auto with "always on" and see how that does with battery, then maybe try number 1 on the same setting. Far as the flat tire that everyone is upset about, I can already say I would have rather had manual adjustment only with a full circular screen. Oh well I did all my homework between this watch and the Huawei. The one thing that gave this an edge was the 400 battery and the ability to switch bands at will. After a week or so I should have a good idea if this was a good purchase.
I got mine last week. For mr it was the 400 mAh battery and the watch face size. Anything under 46mm or a band less than 22mm would look silly on me.
On autp thr active screen is practically unreadable while the ambient screen OK.
Strange thing: my battery just went ftom 92% to practically 0 in what seemed to be less than 2 hours. And the screen was off the entire time.
Battery is great for me. Only lost 20% in 12 hours, about half that time I was using the "always on" screen mode or it would have been even less. I am not going to be a heavy user so that makes a difference, if you're someone who is using it all the time it's going to be a different story I'm sure.

Your graph say that your screen stay ON 62% of the time, so it drop the battery in 2H. Maybe something touch the screen and your watch stay ON ?
I sometimes notice while wearing short sleeves that the screen comes on and never goes off even though Always on is set to Off. I usually notice when the watch or watch face becomes warm. But generally battery life is fine, requiring a charge every other day.
Another reason I chose the Moto over the Huawei watch or any other is wireless charging. No more corroded pogo pins for me!
I am at 33% and still haven't charged since I got the watch on Thursday. I do turn it off at night like I do my phone, but nonetheless that is great far as I'm concerned.

Why does LG think it's ok to ship a watch with a 12 hour battery life, with minimal use. Just setting up the watch took %40 battery
Without sacrificing screen brightness is there anything to be done?? Is there any sort of root + cpu app we can lower CPU speed with??
Did you uncheck always on screen? Only option I have off and notice decent battery life for the entire day.
Mine goes for 16 hours once completely setup. If you start downloading and setting up this will surely tax the battery on any watch. The 240MAH doesn't help, but once setup it should be fine afterwards.
I had the LG G Watch R (w/ 420MAH) prior and setting up took a good deal of the battery but at EOD was at 65%, while the Style is at 40%.....understandable given the size of the battery.
I found mine was going dead by mid afternoon with little use.
I found turning auto screen brightness off and just leaving it on 4 helps. Also think after a couple of weeks use it's got better anyway. Usually on about 40-50% by the time I leave work.
Main problem I have is the little dial on the side is in a crop place, so my hand keeps pressing it an making assistant listen, eating up battery.
Really wish there was a screen rotation option so I could wear the watch with the dial on the opposite side.
Oh well!
I would like to see more options for ambient mode. I think the brightness is too high. I've only found one watchface that lets you control the color in ambient mode. It's called "line". I changed the ambient color to just red and decreased the opacity of the lines and complications. I've been off the charger for about an hour, received a few notifications and I'm still @ 99%. Might be a fluke, but I'm sure using a single color uses less battery than using white, which is all 3 colors combined.
This is my third smartwatch in 2 weeks. I've downgraded twice because others are just too bulky. I'm sure there's a solution out there. I hope battery life gets better in time with updates. I hate this range anxiety.
I just bought one and it is still too early to tell but battery life is fine for me. If I disable Bluetooth (which I know defeats the purpose of it) and WiFi with no ambient, it lasted me about 2 1/2 days (but I do turn it off at night since I have no need to keep it on while I sleep). If I keep Bluetooth on, no WiFi, and no ambient, it lasts the entire day (13 or 14 hours) with about 40% left. I have to do more testing (especially with ambient). You don't want the watch face on all the time anyway because it will cause screen burn-in. Some of the watch face apps allow you to use an ambient where it is usually black and white with less information showing.
Hello. Can anyone help with a battery model? Need to search for a replacement one but there is no info at the internet about its battery nor where to buy it....

Same here.
I looked everywhere. My battery is dead, it drops from 100% to around 30% as I disconnect it from the charger.
Even if we find the battery, the replacement looks hard. I was hoping to just get the Pixel Watch but I guess that's not going to happen.
Hi guys. Today I made a short video with opening of this device.
Enjoy.
