i ran across this....
full article here http://jsharkey.org/blog/2010/07/01/android-surfaceflinger-tricks-for-fun-and-profit/
Looking forward to this release! At work I have a hard time charging my phone. Getting notifications all day and being able to use the phone normally is great but I am work for over 8 hours. If I can click a widget and reduce battery drain while I am not using it....awesome! I can always press the widget to restore when I want to view back to normal. I can see how this would be useless to most, but this gives me the ability to use the phone for that 8 hours and not have the phone die before I get home.
I dont get why anyone would trade a great looking for screen for a unicolor one just for one more day of battery life.....
EPIC FAIL.................
Terrible idea. Why don't we just buy 5 year old blackberries...They have great battery life.
Yeah, this is really dumb.

If you can't use your phone for 8 hours there's a problem somewhere. You probably have apps sucking the battery to death

I haven't had 8 hours on a change since I first got my G1. I never have on my nexus either. But I do use the phone a lot.
Nexus One, Virtual Boy Edition.
I'm running an 800mV kernel right now, with SetCPU at 806mhz...
...I've had the phone unplugged and have been doing normal/daily use. 12 hours and I'm at 72%
/shrug
Heavy usage, phone JUST died, 21 hours use. Thats texts, internet, maps, GPS, and phone calls.

But if filters are posible why can't we change the colors by ourself (reduce the saturation for some who don't like it)... Sounds plausible after seeing this hack, love to see an APK or ROm which have included this... Some Days battery hold for hours and hours, other day my max is 8/9 hours (heavy usage )

well you would get that battery life if your degrading your cpu to Hero standards, lollol
Im overclocking on CM6's standard pershoot .34 kernel and im getting a day always, i take it off charge at 8am and when i get home around 7pm its at about 20-30 percent... And that is proper heavy use, I watch video's on the way to work, mp3, browsing, the phone is actually an extension of my bod lol
I think this is the norm if you want to have the super phone you paid for, and not underclock it and undervolt it into T-mobile pulse territory, lol

Those replying this is stupid need not bother in this thread any long I guess.
For me, usually my battery lasts long enough, but at the same time, the time I might need it would be I've finished my work day and just found I'm not going home to charge it but need to go elsewhere, or like yesterday I had to stay at work and my N1 was needed, but I couldn't charge. When you realise you need to stretch your battery life, you want to know what you should change to extend it. This is just another of those options. It will be useful to have for emergencies.
I for one would like to see this added as an option. As stated in certain cases it could be very useful to be able to use the phone with screen on and lower the battery drain.

I know why my battery drains. I know what apps I am running and I can keep track of all that. I have chosen all my own apps and run what I want/need during that 8 hours. No work around other than turning off those apps. What is the point then? Keep my battery lasting longer but not enjoy the phone and all its purposes? I could always just turn my phone off. No apps running then. Like I said, this would not apply to very many users out there, but not all users are in my situation.

Its due to the fact that android's battery meter is more of a demand meter, so if you don't run it all the way down the first couple times it won't read remaining battery life correctly and try to make you charge when you're at h alf battery.
See threads about calibrating battery.
Hrm. I've had a 3500mah + extended back cover for several weeks now as purchased off eBay. This was before I knew about the wonders of Juice Defender and custom roms that helped increase battery life. This was when I was getting a few mere hours out of the stock battery before needing to charge.
Anyhow, the 3500 did increase life. I'd say it doubled it. After I found out about JuiceDefender, I only stayed with the 3500 for about two days before I reverted back to the stock battery. With JD, I can easily get all day out of the stock battery. It's amazing.
I just took the cover off the 3500 to see if I have two 1200's or two 1500's sandwiched together. I took the end cap off and indeed there are two cells laying on each other, but don't want to disassemble any further. Battery is a nice spare to have.
yes well after I wiped everything to re install mikfroyo .4.62 to fix an error I kept getting something surprising happened.
At 6 am I unit my device each day. Now it is 11 pm and I had 49 percent left. That is with about 70 messages, internet browsing l, reading some questionablecontent comic, reading the articles on CNET, two calls. Bluetooth on for 3 hours, 3 short phone calls. Reading xda using this app. Sendong a few mms, and photo downloads.
Now Idk wtf happening to get this battery life but it is amazing.
I also use the throttle tweak, netarchy toatmods.4.3.4 more havs, battery increment fix, and have never gotten anywhere close to this kind of battery life.... ever....
Just thought it was amazing

First, you can never judge battery life until you have ran a rom for a few days. THe first few days will always be a lot better or a lot worse. Second, did you wipe battery stats? Or run the Battery Calibration app? If you didnt, you could be getting a false reading, and while your phone says 40 percent, it may be more like 10, and your phone could die any time.
Yes I did the full large techniques.and reset battey stats everytime I flash. and I have ran this donbefore as in I had an issue that I had to re flash the Rom. Nothing is different except I wiped everything this time LOL. I know the whole Rom and battery thing jot my first time flashing not the last.

when i was running cm 6.1.2, after calibrating everything and tweaking all my settings just right, on full juice that was about right. the phone sleep was awesome. I would go about 30-35 hours, but with light surfing, texting here/there and phone calls. maybe -maybe some gps but that usually lessoned my hours. under heavy usage i would get 18 hours or so. ...i miss that cm 7 doesn't seem to be anywhere near that.
I averaged 1day 9hrs on CM7...with 3 hours of playing emulators and some calls, ect.

It's just the cynic in me. But whenever I've seen people post ridiculous battery life like this with a stock battery, I immediately discredit it unless I see a picture of the battery usage.
And almost every time I've seen someone post the pics trying to "prove" their amazing battery life, they either
a) claimed to use a stock battery but were actually using an extended one (people went back through their posts and saw that they had extended
or
b) they had almost no display usage

Well first off, I don't blame you for being skeptical, cuz I used to be too, untill I started getting it. And second, I won't say something unless I can back it up.
Setup:

Kernel : Tiamat 4.0.2 / 3.3.7 [both are the best, in my opinion, 4.0.0 breaks cameras, stay away from it.]
Undervolt: Viperboy's bsm -100mv extreme / bsm v2
I don't use setcpu or juice defender.

Look, if you can't keep track of time, that's your problem. I can well keep track of time and have fixed my phone to suite my needs, and able to get 3 hours of emulator play; if you device fails to perform to that task, not my problem. I'm here to provide information and share my stats, as everyone else he does. If you feel the need to post ignorant degraded posts because you may not believe something, then you sir are ignorant. I won't be putting anymore effort into this, so deuces.
How good a single person's battery life is irrelevant. Consistent results among the majority of users is what is needed. The Droid Charge needs to come to Sprint so we can get a day of heavy use easily.

I will not have bickering over battery lifes or outrages claims on this topic..
It is unneeded,
It's really fascinating to me how some people can get over 24 hours of battery life
on the Evo. I don't think I have bad battery life while my phone lasts about 7 hours, but that's at pretty moderate use. Maybe if I just left my phone alone I can get over 24 hours, but what would be the point of that? Just my thought, everyone uses their phone differently so everyone is going to have different battery life.
And its true that the EVO 3D has a bigger battery, but it also has dual core processor and 3D among other things, so I don't think the results will differ much.
Poor signal strength = short battery life.

I believe the newer processor & graphics chipset use less power than those in the Evo 4G so there could be a decent gain in up time.

It seems that many people talking about battery life forget about the effects signal strength, especially if you have several services syncing data in the background.
Personally I find signal strength to be the largest variable in my battery life, not just on the Supersonic but on a Rhodium and a Kaiser as well. I have a horrible signal at my home (no carrier has a decent signal at my home) and with light usage my battery will be dead in 6-8 hours. When I am at work where I get an excellent signal I can spend 2-3 hours on the phone, and receive and review dozens of email and only use about 15% of my battery.
The moral of the story is that the same phone on the same rom with the same settings and usage can perform drastically different in different areas.
Since the beginning of Android one thing has always been an issue with some of the greatest ROMs.
........................Battery life.
Every day lives are drained away by the pleasures and features of such fantastic ROMs... and such things at time seem so hard to bare that we try to change the lives of our battery by going to a different ROM.
So now you have a chance to make a difference, nay, an opportunity to change the lives of many...
This thread is strictly for how to save Battery life. CM9/AOKP have amazing battery life by themselves (but yet can always be made better) But for those on MIUI (Not so great battery life) this will be really useful.
Understand that everyone's device is different and although you may get 15 hours off MIUI/AOKP/CM9 others may only get 4 from them.
Post what it is that helps you achieve maximum Battery life. You may be the one to solve the cure to wowhowdidmybatterylifedroptwentypercentinanhourosis.
Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9, although i think aokp does better.
2. Samurai Kernel, although just about any other ICS kernel should help. The biggest thing that you can change between kernels is the Governor and I/O depending on these two will determine how the CPU runs and in effect will determine battery life. Conservative is just about the best for battery life. If you need slickness and not too worried about battery Ondemand. If you want the best of both worlds i Think Wheatly is a good compromise. Also I/O , Sio is "simple" but VR is flash based so it tends to be the best. Otherwise Noop/Deadline. Also voltage.. undervolting will help limit the amount of well voltage to the CPU. So the lower you can get it the better.
3. Dont have tweaks i apply through CWM but i Run the V6 Supercharger, 3G turbocharger(optional), and the Kick Ass Kernelizer from Zeppelin.
4. I cannot stress this enough, Apps that say they save battery... run... which uses RAM and Resources... meaning its running trying to save you battery, Using battery. Which is stupid... and useless.
5. I have two a 3500Mah and the stock 1.5 year old 1500mah.
6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.
He needs to get over it... lol. The only thing that truly saves battery life is managing your connections. There is no magic bullet unfortunately.
PLEASE! Don't tell us to turn off data and never sync the phone. Obviously if you don't use the phone the battery will last forever. I need a phone that can do the following:
Receive emails and texts as they are sent. (I use exchange push)
Last 18 hours on a standard or 1800 mAh battery.
I can just barely make that with stock FC09, I'd love to run ICS but with either CM9 or AOKP I barely make 10 hours.

Oh my good golly gosh.
I just realized the best battery life I ever got was on DK28.
So take that. Let's go Frankenstein.
1. CM9 KANG June 02 build.
2. Stock
3. Services for V6 and Search Key Remap
4. Ha!
5. Stock. Came with device...need new one.
6. Depends on use. But I usually get the estimated six hours consistently.
7. If you're going to use a task killer just use the built in one. Overclocking is bad, and in my experience so is undervolting. GTalk, official Facebook application(especially this. Even with notifications off it still is always going), G+, and more are always running and are a drain. No live wallpapers, and no widgets that require constant updating. As much black as possible. Don't use third-party batteries. Obviously turning off 3G, 4G, sync, and such will dramatically increase your battery life.
WAIT! Why am I writing this? There is a freaking optimization guide. Why does this exist? For ****s sake.
Running AOKP build 36, stock, FC09 modem 15 hours running takes me down to 50% batt hour of screen time, constant crappy wifi connection in an area with crappy cell signal sync for everything but email and g chat is every 2 hours (weather and all that). Big thing to save batt for me was turning down my screen brightness. I was also getting crappy battery life till i let this rom install run the battery down to 5% twice.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) than my bad bro!

-THIS +9000! An app that spends all of it's time stopping other apps is wasting just as much "battery." I maintain, Advanced Task Killer, with NO, I repeat NO AUTOKILL. Set a widget on your home page, tap it occasionally to make sure everything is closed. Same effect as the built in task manager, but one single convenient tap.

-I use two stock 1500mah batteries and one 3500mah. My wife has the same. All are about 1.5 years old now.

6. Typically with 3 hours of display over a period of 15hours (1500 mah) and around 5 hours of display over a period of 22 hours (3500 mah). However this is on wifi, 3g would deduct these a pretty good amount if you have sucky speeds.

-These numbers are pretty much the same for me. I almost always average 3 hours display on the stock battery between games and internet. 5-6 hours on the 3500, but I'm pretty sure it's not reaaallly the 3500mah it claims to be... . I NEVER turn off wifi or 3G, but google autosync is off until I edit my contacts.

By no means was I saying never enable your 3g/4g.. but the fact remains that the single best way to conserve your battery life is to be smart about managing your connections. I.e. not leaving it on ALL day and to only turn sync on when your actually checking your e-mail.. be that through an app like juice defender or manually toggling. If that's not more helpful than what you posted (UV a lot and don't overclock??? Duh.) then my bad bro!

I don't turn off my connections at all and get great battery life... and seens how the op states don't say anything about disabling 3g or anything id say your comment was the least helpful on the thread... but at least you tried... don't get into a battle of witts with me, I'm afraid your unarmed...

Firstly, I'm not trying to get into a pissing match with you. Its pointless. Secondly, the op makes no mention whatsoever of connection status. Thirdly, while you might get decent battery life w/o doing it.. I guarantee you'd do better if you did. Straight facts.
Edit: I am armed. With a small slide out keyboard.

Be sure to include:
1. ROM
2. Kernel
3. Tweaks that have been applied through ClockworkMod
4. Apps used to save life
5. What battery you use
6. How long your life lasts
7. Anything else that you think may help

1. CM9
2.ShadowKernel (I find nyan colonel to be a little more draining) SIO, conservative
3. None
4.System Tuner Pro configured to UV, under clock to 400mhz on screen off, to close apps that don't automatically restart themselves, configure "auto-kill" so its not as aggressive with killing apps that just stay on, and a few sysctrl edits that I honestly don't think make a difference.
5.stock epic 1500 mAh, my sprint store wouldn't give me an sgsII battery
6. 12-18 hrs depending on use, though it has definitely drained quicker
7.be easy on data! (There kennyG) turn off wifi when your not near your networks, turn off mobile data, Bluetooth, and autosync when your not needing it. (Unless you absolutely need PUSH email for your job or whatever though honestly as far as my job goes if its important enough for me to need the message immediately they will simply dial my phone number. Yeah I'm old fashioned.
- Cm9
- Shadow kernel
- No tweaks
-1800 D710 battery
- I get 15-20 hours depending on how much music I stream during the day.
- I got the biggest boost by using the profiles in CM9 to optimize my connections and syncing depending on where I'm at during the day. I have Wifi at work and home, so I have it toggle my data off during that time period and vice versa when I'm mobile.

Using AOKP with shadow kernel.
Best thing I did to help with battery life was to turn off all notification options in the FB app. And I set haxsync to download photos only when plugged in.

Strange as the concept sounds, I get better battery life when I overclock my Epic. At first I thought this was a fluke, since a faster processor (in my head, anyways) HAS to equal more power consumed. Generally speaking, this is true...
But, here's how a higher processor speed actually helps you reduce overall battery life. During daily use, your phone throttles up the processor to get something done, and then goes back to a sleep state. Mine goes from 100 to 400 to 800 to 1100 (my overclocked speed) as I watch it, with my phone just doing it's thing.
The faster it can get a certain thing done (i.e., faster processor), the sooner it can go back to a resting state, which equals more rest and better battery life.
That's it. Of course, this only works for daily use - if you keep it running playing a few games the battery life will most likely be worse. Has anyone else experienced better battery life by overclocking? I'm curious to see if this phenomenon only effects me
My setup:
CM10.1 - Experimental (Jan 20)
NS4G modem, with nitest kernel and patch (Jan 25)
smartassV2 governer/NOOP I/O scheduler
Overclocked to 1100MHz
hmmm interesting thought... i have never overclocked my epic but im just wondering how are your boot times with it overclocked... my daily use on my phone requires bluetooth on all the time and while i am at work i play music and on breaks i play games so i do go through a battery every 2 to 4 hours (I keep 6 spares on hand at all time lol) if it didnt drain battery but sped up boot at battery change would be worth a try just always been scared to oc cause dont want to mess up my phone...
Wow, six batteries? How do you charge them all?
I've been overclocking computers and such ever since I found the clock switch on my old Packard Bell 486. The trick is to not go too crazy and start small. For example, I have two Epics in the house running at 1100, and everything is going smooth. Boot times seem pretty fast, but the overall battery life is better than it's ever been on both.
I tried to clock one of them up to 1200, and I had a couple force closes and a forced reboot, so I backed it down to 1100, and the problems went away. I've heard that others can run at 1200 all day and not have any issues, so it depends on your phone.
I'd like to hear what happens if you do OC yours - my usage is nothing like that!
Sounds about right to me, the cpu isn't working on the same thing for as long and hashes it out quickly so the battery isn't drained as fast.
Just my view, I'm a slightly advanced computer ****.

Definitely dependent on the phone as you said, back in the samurai kernel days my epic could handle 1500 no problem...
I have 2 external charger that came with 3 spare batteries... ebay like 15 bucks or so for 3 and a charger... I may give it a whirl see how it goes... what rom you using now??? Was thinking of just the regular cm10 but I really like the center clock mod of aokp... but thanks for the advice I will let you know how it goes.

Isn't the default lower-bound clock 200mhz on most roms? Maybe the fact that you have it going down to 100 makes a difference too?
^Pretty sure that all ROMs run 100mhz stock.

While the default is 200, 100 and 200 really aren't big enough a difference power wise to make a big jump in battery life...

In the past week, I just upgraded to a Galaxy Nexus, bit still have 2 Epics in the family. One is on CM 10 and tje other is on 10.1. Definitely like to hear how it turns out.
Although this thread is about overclocking, don't ever let your friend that knows how to change the clock speed use your phone. I let my friend use my phone to play a game, and when I got it back, it was really slow, laggy and hot. Because he thought it would be funny to change the max clock speed from 1 Ghz to 200Mhz.
