dont know if it is helpfull or not but one thing i have found is the autosync drains the battery real fast,also setting the screen to full brightness sucks alot of juice. i have been unplugged for an hour reading the forums and still at 92%,that is good as far as i am concerned,if autosync and brightness were set on ut would be at 75% by now

Pretty obvious? But the screen brightness does make a substantial impact on battery life.

This is pretty well known information.
Every little bit of info helps. Check all auto updating apps as well. they can use lots of Battery power.
What I want to know is why after a reboot on any ROM it seems the battery drops approx. 8-10%? It doesn't take that much battery to reboot a phone. This has been the frustrating thing for me thus far.
Yeah, one of the biggest battery savers for me was turning Facebook from 1 hour to 1 day (auto update). I can't believe how much battery that uses. Set the screen to manual brightness with the Android Power Widget and bam - you've got a phone that can last awhile.
I am using the CM7 RC0.4 and the battery is awesome. Here the screenshot.

Yup, It does drop 10% of the battery usage every reboot.

No offense meant but you obviously haven't used your phone for anything the entire time.

Good info for those new to large screens. The screen is by far the largest battery hog on these phones for me. I find the screen plenty bright at about 30%. Except in the sun of course

in other news, water is wet and the sky is generally blue.
I wish I could get some nice battery life! I already have my phone set at 30% brightness, my auto updates are set at like 4 hours. I fully charged my phone last night and unplugged it when I went to bed. 8 hours later it was at 45% battery remaining. Doesn't seem that good for a phone sitting with display off and doing nothing overnight.
I have a simple question: What is the biggest battery drain on your SamChg?
I'll bet that almost everybody out there though the same thing I did: "That gorgeous Samsung Super AMOLED(TM) display", right?
I mean, whenever I check the Android Battery Use tool, nothing even comes close: Usually, 78%+ of the power is going to the display.
So, if the SamChg batteries are so bad, and the display is sucking the battery the most, how long do you think the SamChg would last before dying if the SamChg had the display on full-time without turning off (Using StayAwake)? 1 hour? 2 hours? 3 hours?
How about: 8 1/2 hours!
I've done it with 2 different stock 1600 mA battery packs now. I've use the phone lightly during those times, so the phone wasn't totally idle (maybe longer life is possible?)
I've read that Samsung had really improved the power drain characteristics of the Super AMOLED displays, and now I believe it.
It also indicates to me that I probably won't gain much extra battery life from turning the display brightness down. I will keep it set on Auto Brightness now.
FYI - Right now, about an hour or so before the battery dies again, I am at: Display = 91%, sensorserver_ya = 5%, Android System = 1%.
I am suspecting the biggest drain I see during my work day is the switching between 1xRTT / 3G (and now, 4G networks) / No Signal - Which is a big battery drain problem I saw in the past.
Your thoughts?
I do know the battery use app in FroYo is pretty inaccurate compared to Gingerbread. It seems it throws any battery usage into the display row if its unable to determine where it really comes from.
For example, if you stream pandora all day with the screen turned off, most of your battery usage will show up as Display. Once I upgraded my DX to ginger, the same activity on my phone would have a much larger percentage of usage going to Pandora and media server, or whatever its called, and hardly any going to the display.... which is correct.
So if you use that app, take all that info for what its worth, until we get Gingerbread.

That's great to hear, I'll have to give that a shot sometime. I will say that you are still better off with lower brightnesses, even though we don't have a backlight its still gonna use exponentially more power the brighter you go. But I wouldn't leave auto-brightness on, while the changing brightnesses don't hurt battery that much, the sensor to change them does, as its constantly polled. You'll see the sensor_server taking up a good bit of life.
Keep it on manual brightness, and just adjust it by holding your finger on the notification bar for a sec, the farther to right your finger is, the brighter it is. If you hold it you can also swipe back and forth to turn brightness up or down.

Didn't know that trick! Maybe I should read the manual one day.
My thanks to you!
Woah, that is an awesome trick! I have never even heard of that before.
Schweet! Thanks! That is a great trick. Another thing that I've been doing that has helped my battery make it through the day longer is turning off my mobile data. It only takes a second to turn it on when I'm browsing or using an app that requires the data.
Yeah, turn off data when you don't expect to use it for a while. Get a 4G/3G widget to switch between LTE and CDMA when you are constantly in a fringe 4G area and/or in an area thats 3G only. And I like the idea of the auto brightness thing. Froyo has had that brightness status bar trick since its been out. I used it a lot on my Fascinate. With 4G on constantly my phone drains 5% per hour doing very little. Its half that with 3G only or data off.

Just grab LTE Switch form the Market. Put and icon on one of your desktop pages and it takes you right to the LTE / 3G Settings menu o you can switch it. IE no go threw all the menus to get at it.
Also remember the screen only uses power when displaying white or color pixels. Black does not use power.
...curious, I set my brightness to at about 30% or so. Some people use auto brightness.
But, do you think auto brightness uses more power (since it is forced to monitor the device) to use this feature?
yes I believe it does, on gb it was constantly flickering bright and dim. If u want custom auto brightness levels, I recommend the "lux auto brightness" app. I use it, and its amazing
Thanks for the suggestion. I'll look into it...
I do hate that when I'm outside, if my brightness is set to 30% or so, I can't see anything on the screen. It is those little things that I miss from iOS from time to time. And of course you can't set the device to 100% or so brightness, because then the battery most certainly would not last all day.
Unless I'm in total darkness I use 100% brightness all day every day. But in the dark it hurts my eyes so I gotta turn her down a little. Battery is still pretty kick ass too:thumbup:

It is funny how in BestBuy they have all the devices on 100% brightness. They do look nice; then again they are connected to power all day
Even yesterday I was playing with the Note. Yes it is impressive. But the size; imagine holding it to your ear while on a call. Exactly...
I have not had any Android phone that I liked the auto-brightness setting on. My wife's Inspire works the best out of all the Android phones we have had.
On the SkyRocket the auto setting always seems to bright for me.
I like Brightness Profiles. You can set what ever levels you want (or quickly turn on auto-brightness). I have mine set up at 4%, 8%, 12 %, 25%, 50%, 75%, and 90%. I have a shortcut on my home screen for quick access.
How much the screen brightness hurts your battery life depends on how much your screen is on, in addition to the brightness level.
Just turn off auto brightness. When you need to adjust it just slide your finger across the notification bar at the top of the screen ..side left dimmer, right brighter that's what I do.
Ya its seems like a lot of people don't know about that trick

I find it cumbersome honestly, I find lux waaaay better
I keep mine @ 100% unless it's way dark. Still get a full day of battery life under normal use too. It's really user preference.
I use juice defenders auto brightness feature. Its better then the one in the settings because it can go way under the min. brightness so at night it saves a LOT of battery since the display wastes the most battery..

For all you guys who need the edge on battery, and dont need alot of screen brightness, like me, then try out this app on the play store called screen filter. (I am not affiliated with this in any way, I just like the way it works). What it does is apply a "film" over your screen going even lower than android screen brightness. Perfect for office setting (like me), at night when brightness is too much (laying in bed playing a game), or where bright lights might not be wanted (movie theater, work, etc...). I personally love it, I use it usually at 75% with the android brightness off, and everything is still visible, just that extra kick of brightness is gone. Sometimes I go down to 50%, but that gets me seeing my reflection just as well as the screen itself...
It also helps to keep out them creepers that try to look at your screen while sending private texts, pics, etc... Helps keep wandering eyes off of the fancy 4.8 super AMOLED display!
You can add widgets to custom brightness settings to suit yourself, I have 4 right on one of my screens that I use frequently!
I recommend this app to anyone and everyone!
It wont let me post links, but if you search "screen filter" it should be the first app. The logo has a white rectangle outlined in orange with a grey circle in the corner. Not too hard to find at all.
I'm almost positive that screen filter won't increase battery life. I think the phone basically "thinks" its still at a higher brightness than what you see, so it really doesn't improve battery life. I may be wrong though but I remember seeing that when I used it on my droid x.

OLED pixels produce their own light (that is, without a separate backlight). Colors are made darker by dimming pixels. If the app makes what's being displayed on the screen darker, it should be helping battery life. The same reasoning applies to saving juice with dark backgrounds and inverted apps. It just only works on OLED screens and not backlit screen types.
Okay. I wasn't sure if I remembered correctly. Thanks!

Lux Auto Brightness works a little better, in my opinion. It can go less than the screen's brightness without the filter look.
Hi guys,
A friends uses auto brightness, and only speaks ~ 20 minutes / day. A few browsing, reading e-mails, games, just got him at 2 days of usage. Not bad in my oppinion, but certainly they should have improved the battery.
To me it seems like the battery life is longer. My first week of use around 9 or so it would be in the red, but using it throughout the day, at 9 tonight it sits at 37%. Yes it will vary depending on use, but mine has been on battery 15h 30m and screen is only 18%. Cell standby is 30%, and chrome and facebook are each 11%. Everything else is quite small compared to those main apps used.
It seems to me it is helping, but it may not idk. I will continue to use it unless I run into a major issue with it.

+1 to Lux. Set your own brightness levels for various light levels. It can make the brightness very low, almost not visible.

I would be happy to get 2 days of usage... I probably could get 1 and a quarter, but I charge mine every night to be safe. Really varies on how much I use it during the day. Some nights I plug it in with 10% others with 50%... I know its not the best for the battery, but I just plan on getting a new one when this one takes a crap. I have a feeling this phone will be around long enough that the option will still be available

Hey guys, i'm wondering what kind of battery life you guys are getting because my droid x is currently getting better battery than my s3.
On Wi-Fi I drain 10% every half hour of screen on time. I should be able to max at about 5 hours screen on time, however the best I've gotten was on 4 hours, on a good day. So I'm just wondering what the norm is for our phones. Thanks guys

3.5-4.5 hours of screen on when all on wifi is normal. 2.5-3.5 screen on time is about normal for LTE. I'd say these are normal screen on stats given the display size, user set brightness, and AMOLED's poor performance with bright colors compared to dark colors. Dark color screens require less light. Bright colors (browser, wallpapers) draw more power from AMOLED displays. I usually get 3-4 hours of screen on time with my display brightness at about 50%.

Thanks for your response. I forgot to mention that I always have brightness really low. You claim to be able to get about 4hrs screen on at half brightness. I'm going to try setting my brightness and see where I end up. Right now I'm at 60% with 1hr 45m screen on, WiFi, minimum brightness. I could max at 4 hours in theory with the lowest brightness. I think my battery is starting to go.

There is always the possibility that the battery is going bad, but your battery stats aren't that unusual in my eyes. I've been thinking of getting a newer battery as well just cuz I've had this one since release date. Seeing if there would be any improvement.

Try a free app called RootDim. Let's you set lower but still very viewable brightness settings. I think most days I set at 25% but the nice thing is the brightness control is a slider so you have more control. Plus you can set profiles.

My own experience
since 1 year I'm using the Zero Lemon Battery 7500 mAh
Have unlimited Data Plan with Verizon - Wifi Tether to my laptop for 10 hours a day
Phones heats up a bit. But, giving me, excellent service.
The main reason, I ditched Apple is because of the extended battery
Not even the so called dedicated Jetpacks don't run that long.
I use everything - Full brightness - High Volume - Vibration - listen to songs - play games very rarely though - may be 30 min. in a week or 10 days.
I PUT FULL CHARGE THROUGHOUT THE NIGHT. IT WILL BE 100% CHARGED by 7:00 A.M.
As I have said, I have been using this for the past 1 year. Still going Strong.
This is the main reason, I'm not upgrading my SGS3.

Well, aside from the reason it's still a highly capable phone and doesn't lack anything of importance over the newer models in my opinion. In fact I have a S4 and my mother's S3 is currently much faster than mine was before the fine dev's around here got their hands on it. Now they are dead even and most apps run identically on both.
Currently trying to figure out why hers won't charge. I have put a charged battery in there and that works fine but it won't charge in her phone. Guess I just gotta take 'er apart and see if there's a bad solder point or broken pins somewhere. This doesn't seem to be a common issue.
