I seems like we have a discrepancy in how much battery life a TF uses in standby. Some folks seem to be burning <1%/hour, others >3%/hour. Obviously, this makes a huge difference in the total time a TF can be expected to last on a charge.
Please indicate how much yours burns per hour. Please ONLY answer if you run your TF as follows:
1. NOT in airplane mode
2. With wifi in the default (run in background) configuration
What setting is to run wifi in the background?
Also, would the number of apps (singned in) and thinks like exchange emails factor into this?

Yep, a lot of things could impact this. But, the dichotomy seems so clear-cut (literally, <1%/hour for some people vs. >3%/hour for others) that I don't think those things by themselves can account for the difference.

I understand and agree. There should be some type of baseline. can you explain what Wifi setting you mentioned above? I have 3 options - Sleep when screen is off, Never when plugged in and Never - I know thats not exactly how they read but its something like that.

The default is to "Never" disconnect...
Dunno how many %/hour, but I've gotten from 14 hours to 17 hours.
Picked up the transformer once in a while, put it down, etc..
Here's a screenshot of the 14hr one, charged it at the end for a few minutes.

So you don't think the amount of data being communicated per application affects battery use in idle?
What do you think about signal strength from the WAP? (being further from the WiFi router, in another room, many walls and objects between the unit and the WAP)

I'm comparing my results to what I'm seeing on the Xoom, which is pretty much identically configured to my TF (same email accounts, same apps installed and running, used with the same routers, etc.). The Xoom uses well under 1%/hour on standby, the TF right around 3.5%/hour.
I'very configured my TF to turn WiFi off when sleeping.
Yesterday my TF was unplugged and unused for a full 24 hours for an 8% battery drain.

The reason there will be discrepencies between peoples devices is because everyone installs different apps. It's these apps that drain the battery more/less, so install a battery monitoring app and check the logs every few days. If you're losing more than 1% on standby per hour, then get a task killer program and tasker, and set up schedules to turn off apps at times you dont need them. Also make sure you have actually set the battery app up properly, by changing the rating it thinks the battery is (to 6600mA) instead of any default value it has.

If you are using Battery Monitor Widget then it's from settings>monitoring preferences>battery capacity. Default was 1200mA on mine originally. If you're using some other app, I've no idea.
As an update, I decided to go ahead and do a factory restore, just for kicks. I'm not experiencing much closer standby performance to my Xoom, about 1%/hour or maybe a bit less. In four hours since the restore, I've lost 5% battery life, and that includes a bit of use.
It's possible that the battery just hasn't calibrated since the restore, and so I'll report back if things return to what they were before. At this point, though, I'm hopeful that something was corrupted or misconfigured, and that a factory restore did indeed resolve the issue.

Coolthanks for the info will have to check out that app. Right now i am using battery indicator pro whicb does not have a option to change battery capacity
Another update after the factory reset: charged the TF to 100% and unplugged at midnight. At 8:00am this morning it was at 78%, so roughly 2.75%/hour discharge rate. At 10:00am (also only on standby) it was at 74%, so 2.6%/hour total for the 10 hours.
The Xoom was at 48% at 8:00am (forgot to note its battery life at midnight), and at 10:00am (also on standby) was at 47%. So, the Xoom on standby is burning .5%/hour, which has been my general experience with it.
Both the Xoom and the TF are configured with the same email accounts and settings, the same general configuration (wifi, etc.), and the same apps except for the Asus apps. Since my experience on standby was roughly the same with the original (non-updated) TF build, I don't think it's the Asus apps that are causing the burn.
If most others were experiencing the same thing, I'd write this off as a purely academic exercise. 2.5%/hour burn rate on standby isn't terrible, particularly since I tend to charge every night anyways. My concern, though, is that if others are getting <1%/hour with the same basic settings, and as I'm getting on the Xoom for sure, then the question becomes: is there something wrong with my TF specifically?
Well my transformer is doing better than that. I lost only 3 over 5 hours. Overnight from 10 to 10 battery went from 33 to 27 percent so looking at 0.6 % per hour. Btw I have wifi set to turn off with screen off. Why do I need wifi going if I can't see the screen. For mail when would wake the device it checks the accounts immediately. So........

I've had my TF with me most of the day letting friends play around with it so it's had what I would consider "normal" use.
Starting at 100% this morning when I left and now has 65% after ~8 hours. (See attached screenshot)
I am battery anal too but anyone else feel like discussing a 2% drain difference in idle is kind of ridiculous.. no one runs exactly the same stuff on their devices of course it will be different... to be honest if you are concered about battery drain during idle.. you obviously leave your device unused alot... in which case battery life doesn't matter a great deal cuz you aren't using it hahhha

Disagree with you. I think standby life is very important because the tablet is something you wanna pickup and have immediate access to for information a nd media without always Worrying if the battery's has enough juice. My nook color can go several days on stby and 3 to 4 days of casual use with standby. This tab doing same stuff is giving me 36 hours tops.
Cm7 on nook color has sleep issues and so doesn't enter deep sleep and so battery drain is about 2% instead of. 2% per hour on stock nook.
maybe our devices aren't sleeping deeply and draining much faster.
Something a Dev. can check?

I'm just wondering if anyone here is getting the super amazing battery life that I'm also seeing. I'm running Virusrom (basically just themed stock rom with no bloat) had my data connections off, and screen off clock speed set to 200MHz (using overclock widget to control speed)
I got through 12 hours on 3% battery. Is anyone else seeing this?
what overclock widget you using? Just curious...

If I never touch the phone I get this

seems alittle fishy since the processor cannot go below 245Mhz.
plus what do you mean by data connections off? No LTE or 3G?
Or do you mean you disabled always-on mobile data? I myself usually drop 10% in about 7-8 hours with that enabled and normal use, with SetCPU telling the processor to run at 245Mhz when the screen is off.
Yea, 245mhz, I didn't have my phone on me, and couldn't exactly remember. No data means no wifi, 3G, 4G. It just could receive/send calls and texts. As for the overclock widget, it's just called "Overclock Widget" in the market.
I am on a stock Tbolt and have disabled the lock screen and GPS when not needed and am getting at least 12 hrs with life to spare. MUCH better then my first day of use
1 1/2 more hours I will reach 12 hours. All I did was to follow this man's tips. I still have 30% left. I'm sure it's nothing new to some of you but new to me as I never had to do this w my old Samsung or Nokia phones.

I have
1. MS Exchange sync every 15 min
2. Gmail sync
3. Facebook sync
3. SipDroid calls for about 2 hours
4. Pandora streaming for 1/2 hour
5. Surf net about 1 hour
6. Xda app about 1/2 hour
I'm happy and i'm still stock TB!!!
Unless I'm actively using data, I always have it off. Well unless it's on charge haha. As for sync, I don't even sync email (gmail), or anything. I don't really count contacts or apps as syncing as it's almost a one time thing. Most people tell my i Baby my smartphone, but I'm the only one I knew that could get 3 days on my Dinc 3 days no charge on stock battery haha.
Uhh... congratulations?! You made your device entirely useless and got trough 12 hours on 3% of the battery.
What is the point of using your Android smartphone without data all day? Is this a pissing contest to see who can disable all of the core functionality of the phone and see how long the battery lasts?
I turned my phone off the other day and when I turned it back on I used .5% of the battery... woah!! That is absurd battery life for such an awesome smart phone.
Sorry for all the BS... but honestly, why go through all of these lengths to prolong battery life longer than 12-18 hours. It renders the device useless and it no longer provides service to the user. I completely agree with optimizing the device (running custom kernels when they become available), using SetCPU profiles, etc... to a certain extent. If those optimizations impede on performance or functionality in any way then they are not worth it to me.
So ultimately, why sacrifice performance and functionality for the sake of ridiculous battery life. As long as you can make it through the day, then no worries. I charge my device every night anyhow.
I've started using this widget as well, I'll find out its effectiveness in a day or two once I leave it off for a while (like overnight). Only complaint I have though - every time I turn the screen on, it says it's been granted su permissions, right above my dock. Is there any way to turn that off? It's just kinda weird too, if I go to show off the phone it looks bad.
Edit: I do have data usage in the background though.
Well honestly, I am around a computer most of the day, sleeping, or at work (can't be on my phone) I was sleeping most of that 3% loss. When I'm near a computer I tether so that charges without me thinking about it, and in my car I have it on charge because of the battery rape of GPS and 3g/4g. It's still a fully functional phone with no data... I can text and talk all I want. And it's not like I don't toggle on my data when I need it. I just don't see the point of being THAT connected to technology ALL off the item, and I'm a programmer, and an I.T. gupy >_>

In the Superuser app you can change that notification. Also, there is a preference for the notification letting you know the clock changed in the widget's prefs. I turn them off. I normally use a smartass kernel as it works with much less power, but this is better than not having it for now IMHO.

I'll tell you why.
1. 4g tether that rivals my cable internet, and I can have both at the same time
2. I always have data and GPS, which is amazing in my car or anywhere.
3. Why no I have to be strung to the internet 24/7 and not just when I want to? It's always there, at the toggle of a button. I'd rather not be lazy and toggle data versus looking for a charger every few hours >_>

Thanks, I somehow missed that setting when I was setting it up earlier.
Also, I kind of agree with what's said due to the fact that 75%+ of the time I'm awake I'm at a computer. I don't need to have my phone do much more than texts/calls during that time. Why waste battery for that? But when I'm not at a computer, I need it, and that's why I have this phone.

Not a problem. We all miss something at times
As for "needing" data, I personally find myself "wanting" it. I don't have anything that I can't let go of on the internet while I'm at work (can't use my phone for anything but texting once in a while). I always enjoy my data, and use a considerable amount of data, but it's either tethered or plugged in as I'm driving, and may as well. I guess being a minimalist is against the law now a days
i get great battery life stock not rooted but when i added adw launcher and gingerbread theme with ginger bread keyboard i went 1hr and it was a 60% and i never touched it so stock my battery is awesome

I think you've missed the point. Noone will last even more than 6 hours if you don't do the trickle charges or whatever you call it. That's the point. I know you reply to OP but just want to point it out. After charging it the right way, you will certainly last 8 hours at least which then bring to your point "I charge the phone every night anhow".

Hi,
just got my brand new Transformer Infinity today and I'm pretty disappointed with battery life - without dock it lasts something between 5 and 6 hours while watching youtube and browsing web and that's not much more than my HTC One X. I found out that wifi drains more battery than the screen - 40%, which is pretty weird, because I'm sitting right next to the router and wifi signal is always stronger than -50dB. Have someone experienced something similar?

Is there a way to check if it's miss calculated or if there is something wrong with wifi module? And if it's actually miss calculated, shouldn't Asus repair it to make sure it is calculated correctly?
your argument might have more merit if you did a test with the wifi always on for a period of time vs without it on.

Since it might be miscalculated that could be wrong. Try watching a movie with another one of similar length without wifi. Afterwards compare battery percentage.
The battery needs a few charge and discharge cycles before you will start to see more meaningful reports. Don't go around and unnerve people by posting about battery life when you cannot possible say anything about that particular issue right now. Let it settle in for a bit. Please.

No, it's not. Li-Ion batteries have hysteresis as well, and the circuitry needs some start and end points to calibrate itself. I would agree that in some cases, like in my SGS2, specific hardware is used that doesn't need as much info as other pieces do, but generally speaking, you can't expect full potential out of the box.
Posted for reference. You can keep believing in your myth busting capabilities; I do not have the illusion I can convince you otherwise.

I agree. As an SGS2 owner myself, I know that when a battery is first used, or removed and put back in, it takes the device a few cycles to properly calibrate the battery gauge to have accurate results. I imagine this is the norm across other devices as well.

Never experienced anything like that since Li-ion batteries came into production.
Btw, just did video tests with wifi on and off, there is almost no difference in battery usage (about 15% per hour with brightness about 50% and IPS+ off), so it seems the battery readings are wrong.
Also I found out today, that auto brightness does not work - stays at maximum level if you go into dark room from bright place forever, exactly the same problem someone experiences with earlier Transformer models. Does auto brightness work OK on your Infinity?

My specimen does the same. Brightness doesn't go down when I turn off the light in the room, and it stays at the relatively high level it was at. So that currently makes three of us.
Using auto brightness on mine now. Seems fine. Regarding the battery usage, i have wlan at. 30% usage after alot of downloading.

Apart from the physical characteristics of the batteries discussed above, it is a problem I have encountered in numerous Android devices - the stock battery stats are miscalculated in so many ways, we won't even have enough time to name them all (I remember users panicking about the dialer "draining" the battery in numerous threads, while in most cases it was only the stat issue showing the dialer using most of the battery after making/answering an initial call).
For some different measures, try different apps from Google Play, like Badass battery for example: https://play.google.com/store/apps/details?id=com.gsamlabs.bbm
According to the review from Taiwan, the Infinity could watch youtube movies for almost 7 hours. The brightness was set to max, volume was set to 50%, using wifi to connect to internet.

Engadget said they got about 9:30 out of the thing. 14:43 with the dock attached. That's looping a 720p video with wifi on, and the screen cranked to 50%. I think with normal usage, you can crank out a good amount of time. You just have to find that sweet spot with battery usage. I know I'm still working that out on my Bionic...but I've gotten that to last all day lately.

After one week of usage mine lasts about 9 hours while idling with 50% brightness, about 4-6 hours while watching youtube or browsing and about 3 hours while watching videos or gaming at 100% brightness and IPS+ on. Right now battery is at 66% after 1:48 of youtube and browsing with about 35% brightness, Badass Battery estimation - 3:06 left. What is battery life on your Infinity?
Good day,
I just got my Infinity yesterday, and as a previous owner of the Transformer Prime, I know the kind of battery life to expect.I am getting around 5 hours of battery, half of what I got on the prime (both with no keyboard).
The strange thing is that the battery usage gives wifi 50-70% of usage. The screen is usually usually around 20%. Does any one else have this issue?
I am updated to the latest firmware: 9.4.5.22

I never owned any Prime but I have the same issue as you. Do everyone else have 50% wifi usage and about 5 hours battery or would it be a problem on some specific models ?
This is only a problem with statistics display on Android, not WiFi draining 50% of the battery. You can understand it as "WiFi mostly on" or something just try other battery widgets with their own stats, you can see my best apps thread.
I noticed the same thing. I was expecting the screen to be the major consumer, just like on my GNex, but was shocked when the Wifi was taking up so much. Yesterday I was downloading a ton, so I can see how it was then.Today not nearly as much wifi usage, and it still is taking 84% of my battery. Down to 89% after nearly 4 hours. Only 23 minutes of screen on time.

Turn off auto-sync and see how the battery life is after a day of it just sitting there.

Well my mistake. The battery life started at 94% (forgot I reset the device) on that clock. After another 1.5 hours, it dropped 2% the way it was to 87%. Just turned off auto-sync and gps. We'll see how it does now.
As far as I'm concerned, it appears to be much better than my GNex. And I have a 41WH battery pack/USB charger for when I travel. I should be great with battery life.
My WiFi % on battery is way high too, but I'm not seeing a ton of battery drain. I'm at 92% after 3 hours with 10 mins of screen on time and auto sync on. WiFi is at 88% and screen at like 7%. Kind of odd but not noticing anything totally broken yet.
Same here
I was shocked at how fast the battery runs down on my Infinity. I've used mine for about an hour and a half so far today and it's at 65% already. Wifi shows as using 50% of the battery and I haven't really done any wireless work with it - mainly watching local videos. I'm getting about 4-5 hours of battery life every day.
Before anyone suggests that it's just a bad tablet - this is my second one. Both have behaved exactly the same way. I have installed Startup Manager and used it to disable all the live wallpapers, etc...from starting up when the device boots and it hasn't made any significant difference.
What's going on...?
location via wifi is the culprit
I also had this issue after I bought the tablet. The battery was drained even in sleep mode which was a clear sign something was not right.
There seems to be a bug with google maps that makes maps ask location way more often than necassary even when no settings for this are yet made..
I noticed this when turning wifi off for sleep to keep battery cosumption down and maps came up the biggest battery hog after this change.
The remedy is to first enable location settings in google maps (you have to do this first to get access to location settings) and then disable all location updates you don't need. I actually turned everything off from maps but I left wifi location enabled in system settings so I can still refresh location manually in apps that need it so for example apps like star chart can get my wifi location instead of gps in my apartment. In fixed location wifi is accurate enough and much faster than waiting for gps signal. So anyway now i can leave the tablet sleep for a day and it will only consume 1-2% at most even when wifi is on.. hope this helps.
I have used this tablet for 2 days now and almost everything works perfect (thanks to latest ota) but there's one thing that is bothering me. Battery life. I had ipad 3 for 2 months but I finally sold it and bought the infinity. Now I know ios sucks on phones AND tablets. But the battery life was amazing. I could use it to browse and for games for 9 hours at least. But on the infinity I am lucky if I get 4 hours browsing. 4 hours sucks on a tablet. But I think that wifi is the problem. I have added 2 pictures were you can see I used the tablet for 1 hour last night then I used it for almost 3 more hours today. Now the battery is at 10%. But I was wondering why the battery uses 62%? On my galaxy nexus wifi is using 5%.
Have I got a faulty unit or is it like this for everyone? If so please let me know fast so I can send it back before it's too late.
Somethings not right there. Tests/reviews done by some major outlets (thinking PC World or Engadget) reported 9 hours of video play over wifi with screen at 50% brightness. iOS has always had good battery life due to their stict contols over the OS, but you should be seeing more then 4 hours. Hell I was at 40% and played WindUp Knight for hours straight last night which takes up much more battery then a movie. I usually don't suggest using task managers, but there is one built in by asus, I'd use it and see if you can kill some processes. Also be mindful which profile is being used. I stick to balanced most of the time and switch to low when the battery starts getting low (24%ish)
http://www.engadget.com/2012/06/25/asus-transformer-pad-infinity-tf700-review/
The TF700 packs a 25Wh battery rated for up to nine and a half hours of runtime. Indeed, it lasted nine hours and 25 in our battery rundown test, which involves looping a video with WiFi on and the brightness fixed at 50 percent.

Thanks for the reply. I am always on Balanced and i am seeing over 20% down in an hour. Maybe i have a faulty unit?
I wouldn't be so sure. I was playing nova 3 on performance mode though.

Exactly, it all depends on what your doing OP. The movie scenerio in the review doesnt take much juice in that it uses the low power single core. I don't know for sure, but web browsing may require all 4 cores to kick in depending on exactly what your doing. Regardless, your wifi being a big consumer is easy to deal with. Somewhere in the settings is an option that automatically turns wifi off when screen is off.

Well, all i was doing was using chrome... I think it's pretty bad when i cant browse for more then 4 hours on a tablet. I thought it had to do something with WiFi since its using over 62%. I did the same test with my nexus where i i just used chrome and when i looked in battery , wifi only used 10%. Maybe there is a bug with wifi?
Try Battery HD for some averages/estimates.
I tend to get about 9+ hrs of reading, balanced mode, WiFi off, and about 7 hrs of browsing over WiFi (undocked, dock charges me about 2/3 full), but it all drops down drastically for gaming, which is about 4 hrs you mentioned.
If you get 4 hrs of pure browsing, I'd consider re-flashing, wiping data and - if these don't help - returning your device.
Chief Geek's point has much merit, and you could always look at (for example) GreenPower or some other time-/screen-based toggler. They do pretty well, and you do not even lose out anything except direct push functionality. (Does it really matter for 99.9% of mail when it comes in once every 15 or 30 minutes? When it does (when you're buying a house or something), shut down the toggler for the time being and cope with some battery drain, then when the situation has resolved, enable it again.
And try using BetterBatterStats for your statistics -- the main battery stat app Android offers has some quirks to prevent meaningful interpretations of many scenarios. Let that get a few charging/discharging cycles and then look at the stats.
So battery hd tells me I should get 8 hours of browsing and 9 for video playback. Will do another test tomorrow with screen on whole time and see how long it will last watching videos. Also battery hd tells me I can play 3d games for only 2 hours. Eh

Remember that these are just averages for your device, at least in the beginning.
If you mistreated your battery upon receiving it, it can kill battery life. You are suppose to plug in your asus tablet for at least 8 hours (well beyond the tablet would say the battery is 100%) the first time you get it. This is sound advice for any new Lithium Ion Battery.
Then you can start using it. Letting the battery die at 0% also decrease the life of the Li-Ion battery every time it happens (ignore old sites that say you should do a full discharge cycle every 2 weeks, that was for old Nickel Cadmium batteries).
Juice Defender is typically a phone app but you can run it as well to detect if any background processes are eating up your battery life.
I get almost 10 hours on my TF700 with moderate usage (mix of browsing, video playback, reading, etc.).

All correct -- there is a lot of disinformation going on with batteries (especially regarding the charging cycles, although a single, long, full charge and then draining to zero charge actually helps calibrate the battery indication algorithms in the device). The optimum minimum charge level seems to be about 40% or so I've read.
Juice Defender and Greenpower toggle WiFi on either time- or location-based profiles, and that works on tablets as well. Recommended!
Your phone doesnt actually discharge a battery to zero. The thing with lithium batteries is they maintain voltage untill nearly the end. This is a very large benifit for modern devices. Once the voltage starts to drop the phones circuitry cuts it off and prevents it from powering on with the LVC circuit that checks the battery before allowing phone to power on then immeditately cuts it (first attempting a power down then all out power cut). This happens to protect the battery. So what the phone considers a dead battery is simply an exhausted battery ready for charge. If a lithium is actually dischardged completely it will damage the cell and prevent it from taking a charge. The power being given to it is then converted to heat. The battery then ignites and very very bad things happen such as your house burning down. The point of all that is to point out that discharging your phone to "zero" isn't actually doing any damage past the normal wear and tear on the battery. I buy batteries that cost hundreds for some of my RC hobbies and have learned the hard way about how lithium batteries work. (bypassed LVC and ruined a $80 3S2P pack)

i have actually read that Li-Ion batteries can be used out of the box. Sp i turned on my infinity right away. I put the charger in, but i still used the tablet. It was about 25% when i got it out of the box. So what you're saying is that i have basically ****ed up the battery? If so, then i will return and get a new one. But i dont understand why most people say that you can usre a device with Li-Ion battery staright out of the box without needing to charge it first.

Nothing to add, technical and extensive, but fully correct, sir. I think we may have had a slight misunderstanding, however: my point was that discharging your phone to 'zero' (and as you rightfully point out, that is not an actual fully discharged battery state) is a required step in calibrating most device's algorithms (some devices, such as my SGS2 do not need this because of advanced hardware). I'd rather not fully discharge any Li-Ion batteries either.

A typical case of RTFM, an affliction I sometimes suffer from as well, as do most men. Hahaha! Do you think ASUS put it in the manual for laughs, or just to give you a few more hours of painful desire to use your device while you cannot, yet? Nah, it's there for a reason. Sometimes, though -- and again that's SGS2 experience -- just running a few battery cycles might make the readout correspond to the actual battery level again. You could at least give it a try, right?

I see the same picture here. Looking at the battery stats I see WIFI using >90% of the battery when surfing in balanced/50% backligt mode.
Hope they fix this.
This is a little bit of a boast, I guess you could say... but also educational in a way.
This is my most recent battery life. I found that when I posted my screenshots, people think they are faked in some way. (Posted it here and other GS3 forums) They are not. I am using the stock battery my phone came with. NOT an extended battery. And you can see from the battery graph that the phone was not charged. I guess this is to show that you can use your phone heavily, and still get amazing battery life.
I am using the stock jellybean leak. Not rooted or unlocked.
This is everything I have done to get good battery life.
-I turned the LED touch lights off (I don't like them, they're so bright)
-I have all vibrations off. My phone does not ever vibrate.
-I have power save on.
-I have S-Voice "wake command" off.
-I have motion control disabled.
-I am almost always on wifi (work & home)
-When I am on wifi, I turn mobile data off.
-When I am going to bed, I put my phone in airplane mode.
-I rely heavily on the task manager, I clear my open windows and under the "RAM" tab I clear memory. Probably once an hour.
-I have my sync OFF. I check my email manually.
-Auto brightness.
-I never partially charge. I let my battery go all the way down to 1% then I charge it to 100%. Always.
-Always have a dark background, if possible.
Thats everything. Mind you, I didn't make or receive any phone calls on this cycle. But I did use my phone, as you can see I didn't just let it sit around. Device idle was like 3%?
Anyone else a "hypermiler" like me? I don't get this much screen time every time, it ranges from 5-7. I've gotten more than this and I've gotten less.
Hope this can help even if it's only a little.

-Clearing the ram too much actually drains the battery more because certain apps will have to auto start again every time you clear memory
-Keeping it at around 0-30% all the time should save you more.(I can still see my screen during the day at 30%)
-That doesn't do anything.

-Are there no A/C outlets in your bedroom?
-What the previous guy said, this is a stupid thing to do. Java was designed around efficient use of resources, and restarting running apps (which would happen, unless you have them removed entirely) would use more processing power than you had saved by not having the tasks running in the first place.
-Using Auto is causing the system to periodically poll the light sensor, draining more battery than used otherwise.
-This is how you kill Li-Ion batteries (one way, at least). The whole spiel about discharging fully, THEN charging fully or the battery will have some sort of "memory" of capacity less than actual capacity is how Ni-Cad rechargables work, not Li-Ions. Li-Ion batteries are the opposite. For superior life, keep them topped up as much as possible. FYI
I hope THIS helped, more than a little.
There are plenty of outlets in my room. Lol I just don't need to use them that often as you can see also I hate getting calls and messages in the middle of the night but I use my phone as an alarm sometimes so airplane mode just seems convenient.
This is just what I do. I mean, some of the things I do may not help at all. But this is what I do with Android phones and I've always gotten really good battery life. I've always, always gone down to 1% then charged up to 100% and I've never had a battery go bad on me. Then again I only ever keep a phone for 1 year. I do know that these batteries don't have the memory problem, I just can't bring myself to not fully discharge or charge. I have mild OCD, for real. Little things like that brother me
I'll play with backlighting to see what that does for me.
I've gotta be doing something right. Idk about the task manager, I've just always liked not having programs running if I don't need them to be. I know they arent "running" but it just gives me peace of mind, I guess.
Thanks for the recommendations I will try them.

You getting really good battery life =/= you getting the best battery life possible.
I have pushed ~2 days of battery life without charging many times on my GS3 (with all the bells and whistles running, just mobile data turned off when i'm not commuting), i just don't have a reliable measurement because:
1. I'm flashing mods/roms/kernels/whatever multiple times per week, and
2. I usually charge my phone when it's convenient, which is fairly often.

I stopped flashing because of my OCD. I mean, I'm not crazy but it causes perfection issues and all the ROMs I was flashing had glitches here and there and Idk if you've known anyone with OCD but with the perfection issue, those glitches were all I could think about. So there went flashing. Lol.
Also comes into play with the charging thing. You seem knowledgeable in what you said but even though you said keeping it topped up is best, in my mind, that's destroying my battery. Lol. I really do appreciate your info though.

I read your post and the first thing that came to mind was, "there is medication for that, you know.":laugh:
Here's my .02. My battery never lasts that long. Not even close. I'd feel disappointed if it did. I bought my gsiii with the intent of gobbling up unlimited data and using the oc'd processor to run apps till the phone is so hot I have to set it down. I've burned up almost 6gigs of data since the 7th. I get around 4 hours of screen on time most generally. I also throw it on a charger whenever I have the chance. My battery rarely dips below 50%. Like others have said, full discharge cycles are for ni-cad batteries. Li-ion doesn't benefit. Good battery life for me is the lg flip phone we have on a diff line that lasts a couple weeks.

Okay, okay, as long as you admit it... I'll stop being a snarky jerk. I'm totally the same way though. Perfectionist to the core.
It's a very bad idea to let the battery go down to 1% regularly, lithium batteries should be charged more often for better life and more cycles
Sorry but I still just don't believe 7 hours of screen on time. 4 is above average even amazing screen on time for this phone and stock battery. I suppose there is the possibility of using 0 percent brightness, or even lux brightness or something similar to get the brightness even lower.
You said you use auto brightness, I'm sorry I just don't buy it.
People with the extended batteries are getting 7 hours of screen on time not stock batteries.
7 hours of screen on time is literally double almost every other phone on the market with stock batteries. I really fail to see how having minimum usage and a high performing rom will get you double screen on time.
Edit: with that said, in my current situation I will never have wifi access plus I tether a lot so I really have yet to personally see screen on time since I rooted. Before root and stock I got about 3.5 of screen on time.
Not trying to be a douche or anything just very curious about how 7 hours comes about.

you dont get 7 hours because you are not doing what op did for perfection, and you just like other "4 hour" guys in this thread. I can confirm 7 hours usage is totally possible and what left can support one day idle time when you turn off data etc. Iusually dont do that because I like my phone work at full functionality, but I also like tinkering around to keep maximum use of juice, by eliminating wake locks and autostart.
killing background helps sometimes because some stupid apps keeping using cpu after backgrounded. op go and get a iphone, its perfect for OCD since it can get zero unwanted background activity, amazing idle time and stable usage with relatively easier configuration and tweaking.
1% is NO. 1 battery killer, heat is NO. 2, top up at 100% is NO. 3. Li based battery is at best 40%. but plaese its just a phone, charge and use anytime you want. phone outdated way earlier than battery.

While I understand what you're saying I think you misread my post. I was strickly referring to the screen on time which 7 hours of screen on time with stock battery is inconceivable. 4 is about the most you would normally see.
7 hours of USAGE is common.

Well I mean. You don't have to believe me. I mean I have nothing to offer but my word. I do use auto brightness. But because of the suggestion I'll probably set it to manual and see what that does.
I got 7 hours screen on time with the stock battery. The battery says "3.8 v li-ion battery"
I've gotten more than this is the past but I've also gotten less.
Like I said you don't have to believe me but... I'm using the stock battery.
And to the poster who mentioned to get an iPhone - I have one for my business line

battery statistics are poor statistics in general. there are too many variables. luckily we have removeable batteries if we need mroe juice.
heres some postings to add to the mix
put my phone through the paces with fantasy football.
held up pretty well. stock battery mind you. on pace for nearly 8 hrs of on screen time. This isnt with typical use though... With typical use I can get 20hrs and 5-6 hrs of screen time. I thought anywhere from 4-6 hours of on screen time was what people were suppposed to be getting.
Yeah we all use our phone differently. I rarely actually talk on the phone with my GS3 because I use my iPhone for that. But everything else I do on my GS3, reading news, some browsing, xda.
I just thought I'd share what I do for people that may want to get better battery life.

Then I shouldn't use the word "usage". I meant 7 hours screen on time. Sometimes I got 8 or more, but only use it continuously after charging, no idle time.

Yet that involves turning off data. IMO the smartphone should always stay online. In my experience, iPhone can get constant -4 ~ -5ma juice flow during idle even with data (2G) and all the push notifications on, which are the only things I want for stay online. I feel its hard to get similar result on my GS3 though.

I'm always online, whether it's wi-fi or 4G. Luckily I have wi-fi at home and at work.
Like, literally as I'm walking out the door of my house, I turn on my mobile data, and when I get to work I turn it off. When I'm leaving work I turn mobile data back on and when I get home I turn it off.

what you did is pointless. If you leave data on, data is not connected when wifi is connected, and it will connect automatically when no wifi connection.

It's not pointless to me. As I said a few posts before... I have OCD, obsessive compulsive disorder. Things like this affect me. I know that being connected to Wi-Fi that data is not connected, but in my brain, it's as if something is telling me that because my data toggle is on, it's running.
I really can't help it.
