Alright guys, ive been hearing different things.. people are getting an upwards of 9 hours of battery from like using texting and that sort of stuff.. stock kernel and rom will give you 5 or 6.. Ive heard some people get 18 hours of use from texting and what not..
Basicly i just want to learn to see what different kernels and set up everyones using and to see how many up hours (like a text or 2 every minute or 2), they get out of it.
Really curious to discover new android things especially battery power with a 4.3 inch screen
Im running Chopsuey kernel with nocturnal shooter sense 3.0 rom and sitting at 768max 245minimum
(yes i made a slight topic typo D=.....)
ICS / CM7 ROM
Kernel : Tiamaat 4.1
undervolted -100mv, 825mv floor
Smartassv2 governor
Battery life: 2 days+
nice to hear you get such good battery life.. i get about 6 or 7 hours of medium usage
I get abysmal battery with every kernel except poonsense for whatever reason. Lasts me all day with texting web phone calls constantly. Seems like setcpu actually makes my battery die quicker

Did you do a battery calibration? If so not download free battery calibrator, charge you phone too 100% the which is I think its 4200mah. Install setcpu? Change different governed see what works with your phone. I recommand to try different kernel see what works.
Sent from my PC36100 using XDA App
I never believe anyone's claim for 2 days of battery life on a battery of any smartphone.
The most I ever got was at least 8 hours under moderate use with about 40% to spare at the end of the day.
This was achieved using a combination of a froyo rom (myn's twopointtwo) with nets 4.3.4 havs-cfs-more-sbc kernel under-clocked with set cpu and juice defender toggling my mobile data on/off whenever it was needed.
Highest I've personally seen is 18 hours of high use

Not sure if you were asking me or teh, he would be the guy to explain undervolting. I don't use any apps or scripts to uv. Just the setup I posted. Proper battery calibration will probably do the most for improving battery life though.
Btw, I just realized those screenies were not from the Xplod rom. I believe they were from the TN stock, and I would of been running the Chopsuey kernel. Same CPU/governor settings tho.

I'v been searching for this topic, and cannot find anything. Hows your battery life on this phone and how do you make it better? I heard CM7 is amazing, but I love Sense to much to give it up.
Try ice glacier I just started running it and its just like sense without the bloat, and with some optimizations. I get great battery life with ice glacier paired with SetCPU.

IGv1.1.6 seems much more stable and using less battery than IGv1.1.5. Haven't setup SetCPU yet as I am just cURLing close to 8.1gb apk.lib archive. Let me be finish ill thoroughly test it, but seems better than before.

CM7 = CyanogenMod 7 (AOSP2.3.1/Gingerbread) ATM its still under alpha and many things needs to be worked out as I use to flash it nightly before IGv1.1.6 its still under RC so wait for the SR if you want it to make it your own stable rom.
my experience so far..
MIUI i get 1.5 days on a single full charge....
evil's desire hd rom id get about .5 days on single full charge, needed a charger.
both had setcpu with just the screen off profile and set to 1.5 ghz oc...
im sure CM7 has pretty good battery life.
BTW for those of you who is saying you get this and that show me screenshot of your awake time don't matter about what you get on uptime.
Battery was at 56% when I shot the image below. Phone is stock and unrooted. It's my wife's, mine doesn't last as long since I'm always playing with it. I'll root mine (maybe) in the future when I get sick of all the bloat (already there).

You saying you OCed 1.7GHz and ran for 16hours? LOL no way man and why do you need 1.7ghz? ATM my SetCPU scale profile for mCPU is max: 1.6ghz/avg: 1ghz/idle: 768mhz and I get around let say 16-17hours. But no way are you getting 16hours running it at 1.7GHZ native unless thats your max on demand or something.

I would also have to vote for CM7. I've tried every other rom and CM7 is best on battery and its also the BEST ROM out there all around!

Ice glacier v1.1.6 with granks kernel v.05 always gave me around 18 hours, and I'm on it pretty good. I'm on CM7 build #16 and its giving me the same if not better than the glacier setup. I use setCPU on both.
i'm on CM7#19 and i am getting good hour usage. i have BT and GPS on always and i'm still getting like 12-15 hours per on good use. along with crappy signal at home so i'm happy.
My battery life blows and it's not for a lack of conditioning or calibration. I know how Li-ION batteries need to be calibrated and that they only last for about 300-500 charges. So I'm basically just kinda getting ****ty battery life.

Well, your issue isn't the Evo itself, it's your personal phone.
I too had a bad battery. Use or no use it lasted for 6 hours max. Said f it! Got extended battery. NOW its a manly man's phone! It's got some girth! Feels like a brick lol. But I'm also a power user. Even so, 17 hours of use on first full charge. Definitely a top mod in my book.

Try an SBC kernel cause battery calibration isn't ur answer. Also its not ur phone its ur kernel and also the governor and oc settings u set on ur phone.
free the dirk
Deck 1.3d. Tiamat 407 SBC. Conservative governor. (Start w 384min and 998max) Play w the values a little. Battery calibration app. V6 (optional). Don't see how it could go wrong. My battery has me in love w my Evo again after almost a year of owning it. Sense is a resource hawg. Until gingersense can figure out how to get the battery life froyo sense had it wont be back on my Evo anytime soon. I lost a t9 dialer going to Aosp...the theme engine makes up for that as mixer looks nice.
No kernel, voltage modification, or ROM is going to change the fact that your battery is bad.
I'm going with what Matty said as you all don't know what I've gone through with this phone. I've gotten all of the mods I was supposed to. I did everything possible I really think it's just a bad battery

Why would you ever need to have the screen on any brightness over like 35%? I keep it almost as low as I can on MIUI, sometimes a little higher if I'm in a bright room but never above 50%. That might be your problem. Brightness changes between 50/60% and 100% are hardly noticable unless you're in direct sunlight or something, at least in my experience.
I agree with sagadieu. I have mine on the lowest brightness (11% I think) whenever I'm indoors. It's plenty bright. If you go outside just touch the far right of the notification bar to give you 100%.
I really think the auto brightness is one of the worst functions and is the biggest battery killer!

The 1.44 option is there because some people want to overclock as high as possible, but some phones won't run at 1500mhz stable. They want more than 1400 but can't hit 1500 so glitch added 1440 after doing some testing on which mhz between 1400 and 1500 is the best.
And you can undervolt to get rid of the extra power usage.

No mod or anything?
The best way I think to conserve battery is to turn off your 3g data when you're not using it. When I was running CM7 with tiamat 4.1 I could easily get 40 hours of battery life without 3g data on. Idk if you're not wanting to make some software changes, flipping off the 3g could save you a significant amount of battery.
Il pass on that lol. Where I live, connection is 0 to 3 bars and no 4g. My 3g is only like 100kb/s of data speed. It barely works with anything data related unless I have WiFi on. No 3g and my phone is screwed without data
What's the point of having no data on your EVO? The best thing you can do is spend a little bit on an extended battery. I've got the pretty much the same setup as you and I'm at 24 hours right now. I got 2 3500 batteries for just over $20

I would highly recommend Juice Defender Pro if you aren't already using it.It does an excellent job of toggling 3g on and off at specific intervals.

try the lionfish kernel... I'm getting about 15-22 hrs of battery life depending on my type of usage...
Try a Senseless ROM, aka mine, Jamie's or Graynodes. Sense takes a lot out of the battery life

Im in a similar situation signal wise and that is a huge culprit for battery drain! Also, try using stock, cpu speeds and voltages and ondemand governor. I can almost assure you will not see a difference if not get better battery life stock, im not convinced by under clocking or under volting. I've tried about everything...

check my signature for ROM and kernel info, I'm using car O dope tweaks with vipermod.. Awesome battery life
Oh and btw I'm on the stock OEM battery

I can't speak for underclocking, but undervolting makes a huge difference, and so does your governor.. Maybe you weren't setting your **** up right? But yeah my suggestion to get the best battery life is to use an aosp ROM, try tiamat out mason kernel (use smart ass v2 governor with mason), and undervolt...

you dont need to spend money on an extended battery that is huge and cant fit in your pocket anymore.
if you undervolt correctly this phone should go around 40 hours on battery, which mine does now. you can undervolt safely -75mV on the Evo 4g.
You can also try an app like BetterBattery Stats. You can get it from this XDA Thread:
http://forum.xda-developers.com/showthread.php?t=1179809
You can also buy it from the Google Play store to donate to the dev.
Either way, it will show you which things are sucking down your battery. If it turns out to be your 3G data in a low signal area there isn't much you can do, but if it turns out to be some app or other service you could disable them to get back some battery life.
Good luck!
