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.

As would a spare battery..
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.

FO3 FTW!
Uptime: 2hours 27minutes and x amount of seconds and dead.
did I break the record for stress testing it?
Anyways, anyone got any tips on battery life? I was thinking of getting 3000mah or 3500mah, but the design of it (bulky) just doesn't seem the right option in my mind.
Also anyone here actually have the 3000mah or 3500mah so they can chime in on the design + battery life compared to the original?
just powered the phone back up. and it says battery is at 50%. wtf.
It turned off on its own cause of low battery, and now it says 50%?
E-gad the ghost recharge strikes again.
I had the same thing happen this morning. Woke up to a dead phone, plugged in, boot ed and battery showed around 70%... Go figure

Battery may not be calibrated correctly. I have to say my only major disappointment with the EVO is how the battery life is so tied to the particular rom I'm using. I mean I expect different drain rates on different roms, but having to recalibrate the battery every time I switch roms is just plain dumb.

Juice defender did not do it for me either. I got 1.58 but too many things were turned off to get there. What is the purpose of a smart phone if everything has to be turned off to save battery.

It used to work for me, but now it is doing the same thing. Im at 1.76 now but for the past week it was stuck on 1.00, then slowly went up with each flash.
just a quick update. The reason the battery showed empty one minute and then it showed 50% the next was because of the heat. The phone was very hot when I was playing with it, and then when it cooled down it seemed to have fixed itself or w/e. Happened again today.
im sure its been answered..but how do we calibrate the battery?
Pretty sure you can erase the battery stats through clockwork recovery. Also there is a way through ADB which is pretty easy too
Sorry I don't have any links atm.
Aren't we supposed to have better battery life especially since the JIT compiler is on 2.2? My slide ever since I rooted it seems to get pretty bad battery life using around like 8 hours using it all day for email and ****. But when I had the espresso sense stock ROM I could easily get 14 hours of battery life on the same usage.
Just wondering maybe some mem suckers or something? I'm not using live wallpapers either and I stay on wifi pretty much at my house all day.
I'm on the latest CM6 nightly.
Sent from my Mytouch Slide with Cyanogen's latest mod.
Boot into clockwork recovery. Hit advanced, wipe battery stats, reboot.
I've been using the 806 kernel (thanks dumfuq) with roman's 1.8 ROM and honestly, if you load up the latest SetCPU (I didn't use it much previously), it does the work for you.
I set up 3 main profiles and a couple others. Basically, I wanted whenever my Battery was < 100% to run at max/min 806/600 conservative(but i change this time to time), then Batter was < 15% m/m 600/400 powersave, but the profile the rules all will be whenever my Screen Off m/m 245/245. Now that can be a pain for letting your phone go while it does stuff because it does run a lot slower then while it's off, but honestly this does the trick completely, I've had freakin sick battery life.
Thanks for the replies. See its not too bad its just significantly lower than the slides ota update stock. But I am runing set cpu and that seems to help out alot. Post me your exact profiles and ill try them out. Also I did wipe battery stats and **** when I first flashed everything over but thats been like 4 nightlies ago. Ill do it again tonight when its dead and then recharge it all night.

In order, here's how I liked mine (but again, itll vary on your usage and junk..)
Type=Screen Off, min/max=245/245, priority=100, gov=powersave
Type=Charging USB/Full, min/max=806/600, priority=95, gov=ondemand
Type=Charging/Full, min/max=806/600, priority=90, gov=performance
Type=Battery<15%, min/max=400/400, priority=75, gov=powersave
Type=Battery<100%, min/max=806/600, priority=70, gov=conservative
Obviously, I'm still working and adjusting but for now this is how Ive been running and really had some great bat life. I may change the governor at any given point for perf. purposes, but usually this is what Ive had it at for a few days. If you have any questions feel free to PM me and I can help you out a lil more too man.
Thanks
TJD319 i gotta say thanks also for those profiles, I made a CM6 youtube vid for slide thats uploading and i want you to know i gave you full credit for the profiles that i use. they really are a big help, so i want you to know that.
I also would like to say thanks, with your profiles TJD319 my phone has been running mightly fine, no problems!
Remix, cool video, would be a nice refrence for people looking into overclocking/flashing cm6.
I'd also like to thank you for the profiles. I set them up yesterday and as of right now (on #TeamFenix 1.8 with the recommended kernel... not 806), I've had it unplugged for 27 hours and I'm at 38% battery left.
Thank you!

Only the best one out there, called Setcpu. Dont use any of those other ones, setcpu is in its own league.
I downloaded and set up SetCPU for only the screen off @ 245, and wow that alone has helped battery life immensely.

What does that do and how does it affect battery life?
I am yet another VERY satisfied Setcpu customer. Major improvements on an OC'd rom. The cool thing about Michael Huang is he posts the app free here on XDA. Seek and ye shall find.
I'm thinking about going back to the 806 kernel. When using that on CM6 with SetCPU I got up to 4 days with regular use. Now it's 2/2.5 with the 844. I suppose it's a drawback for wanting to play Final Fantasy 7 smoothly.
You guys need to understand the profile settings to realize what you're doing with them.
Powersave: always runs at the minimum you set.
Performance: always runs at the maximum you set (mainly used for benchmarking).
Ondemand: starts at your min, and clocks up according to how much cpu it needs. For ex. if I have it set at 400/806 ondemand, it stays at 400, goes up to 600 if it needs too, and then goes up to 806 if it needs to.
Conservative: same as ondemand, but tries to stay lower if possible.

In the off chance your battery has been improperly calibrated, this will give you the chance to recalibrate. This goes for all android devices. I have had to do it once so far with my slide. The battery wouldn't last longer then 8 hours. Wiped the stats, recalibrated, and voila.

let your phone die. turn it back on, run it until it dies again. keep trying to turn it on til it dies and worn't turn back on. Then plug it in, still powered off, and let it charge til the light turns green (should take 3-6hrs, patience...). Boot phone, still plugged in, and let LED turn green again. Reboot into recovery. Wipe battery stats and dalvik cache. reboot. let your phone settle for about 20 minutes before unplugging it. this should calibrate your battery.

first off, i love this phone. no joke, but the battery is well...laughable to say the least. on my HD2 running android, i get double the battery life and they HD2's battery is a 1200 battery, the EVO'S is a 1500. and android boots off the SD CARD and has NO POWER MANAGEMENT on HD2'S. my evo dropped to 54 percent battery today in 3.5 hours. no wifi, no bluetooth, no GPS and no 4G...all im saying is... WHAT THE ****!
It gets better. Load up some custom kernals + setcpu and you'll get great life. I'm running CM6 + snap 8.2 and it lasts the whole day with moderate use.
Sent from my PC36100 using Tapatalk
There is plenty of info on battery issues with EVO.
First... I would recommend rooting.
Second, use the FRESH build based off the new OTA leak.
Finally, change Settings / Mobile Networks / [uncheck] Enable Always-on
Then... ALWAYS keep your WiFi radio on. Add your home network if you have one... and wherever you go, add whatever hotspots you are in proximity of.
And if you ever consider doing a new build, backup your WiFi access point data via Titanium Backup before you do.
That should just about cover it... You will get a full day of use PLUS some out of that battery.

i rooted my phone within 2 hours of purchasing it...i will look into what you mentioned later. im gonna condition my battery for the 4th time in 5 days..
PS those 3500mah batteries on ebay for 10$ and the same 2000mah batteries.
If you get one, get a seido. I just bought 2x1500mah batteries from tuttoit, great backup batteries... charger too 9.96$ shipped.
Oh and I am getting great battery life with snap and cyanogen's rom.
yeah i am going to look into all the batteries, and i love sense, that is why im not on CM6. all my other phones are running it (G1, MT3G HD2). now that i have a phone that runs sense naturally, i dont wanna change it. i love sense! and this thread was just a way for me to vent about my crappy battery.... lol

When you rooted it, did you also flash the newest radios? Trust me on the fresh build.. it rocks... but also, most importantly, use WiFi whenever possible... and turn off "always update"... those are all the most important.

No when I got my evo I was clearly.told and shown a doc from sprint (the manager over mobile area is a buddy) to tell everyone to expect 6 hours of battery life with normal use. I was able to squeeze out 8 - 9 myself. I know people say conditioning the battery is a waste of time . IMHO do it I noticed a nice increase in battery life. I have to laugh at people who get pissy about battery life when they are holding a mini PC.
Myself i avg. 18-20 hours a charge with normal use. I have 2 backup batteries so I don't worry to much about juice
from the fade
I really dont feel the Evo is a bad phone h, hell I love the damn thing . I just feel HTC kinda screwed up things in the process . One telling customers to expect 6 hours of use is alittle of a joke . Who the hell only works six hours a day ? Or is that six hours also include you getting up getting ready for work then coming home before you go to bed ? Second , its pretty clear the Evo has a bug in its charging system . People have reported that using stand alone wall chargers to charge the batteries they are getting improved life out of the batteries (Sorry I have never removed a battery from any cellphone I have had in the past to charge it and not gonna start now) . Third yes the HTC Evo is litterally a pocket pc with capabilities most phones dream of having . Then why the hell did they give it a 1500mah battery ? Thats like strapping a 55 gallon drum of fuel to the space shuttle and saying "Yeah this outta make it" . Sorry for my rant had to get it out (plugs phone in to charge again) LOL
OP, I like you, you're funny
A couple things..
1) Why do you have your CPU governed below 700mHz while awake??? You won't save battery that way, your phone runs at a gHz, use it!!
2) Setting your min/max both at 245 on sleep will actually decrease your battery life and your phones wake up performance, maybe not much. Capping your phone at 245 when asleep makes it a harder transition to awake because it makes that sudden jump when you wake it up. Setting your max somewhere over 600 on asleep, and setting it to OnDemand will ease the transition from sleep to awake.
There is no shortage of battery life tips but here's one: The auto rotate function polls for g-sensor status like once every 15 milliseconds. I use a switch on my homescreen to turn it on when I want it and keep it locked in portrait when I don't need it. This will help conserve some juice
I'm only scratching the surface here, I'm sure you do realize what a wealth of info there is on the subject already. FWIW, I use the crap out of this phone and I consistently get 20+ hours out of a charge. Good battery performance is achievable!

20+ Damn, what rom and kernel are you using? Im kinda having the same problems too. Im limiting my phone tryin to get better batt, that ****ing sucks. I just want to use my damn phone, without much sacrifice. Thanks
Why the hell do you have 4 phones running the same OS?
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.

Why must people post unhelpful comments such as the one above? I don't understand the logic there...
anyways since this was aimed at miui I get pretty good battery life with it... (3.5 hours screen on time) nyan v5 ftw! No special features... uv a lot (won't list my settings cuz every phone is different) and no oc... used to use jd but, it saves more battery if you just switch things off manually... really though until I flashed nyan my battery life was atrocious, but now just about on par with the peoples rom (4.5 to 5 hours screen on time!) Oh yeah, all this with the stock battery...

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.

On aokp with 1800 mAh i can do about 3Hours of screen on time and 15 Hours of battery life and my phone was awake 75% of the time.
Screenie was at 15%
This was stock Everything Except ROM haha

Think about if your screen was on while the device was awake..your time would be cut in half

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!

Something we can all get behind here... I remember I used to get 24+ hours on froyo w/o customs kernels. Le sigh..

1. CM9, although i think aokp does better.

-CM9 still seems cleaner, but AOKP seems better.
ÜBER™ said:
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.

-I don't use the supercharger, but I do apply the same oom ram mods. These help close unused apps when they exceed the applied limit. Based on my experience, it's kept apps under control.

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.

-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.

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.
Click to expand...

-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.

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.
Please follow the format specified by the OP. List the 7 items. Bickering in this thread will not be tolerated.

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.
