Hey guys, im using MikFroyo 4.4, stock kernel, no app killer. Im getting about 15 hours of what most would consider light-moderate use.
Im wondering what i can do to extend this without losing features. Is anyone getting better battery life and if so how?
custom kernel? overclock/underclock? other tweaks?
Thanks.
I use an SBC kernel (SBC #15 v7 from MS79723). There's rumors that it causes battery meltdowns, but from my experience I find that highly unlikely. I've been unplugged for 11 hours and I'm at 60% with what most consider moderate usage (about 100-150 texts, some light web browsing, a phone call or two, a few levels of angry birds). I'm also using Slayer's Cyan Dragon theme which looks badass but I'm not sure what it does for battery life (lessens it, makes it better, i dunno). The set up seems to be working pretty well after a couple of days of the kernel reading accurate battery stats.
I also reboot every morning when I wake up before I unplug to close any programs I still had running from the prior evening. Hope that helps.
Cool, anyone else using the same? different? Thanks guys
I too have been using SBC kernels for a while now with no problems and excellent battery life. Im also running a rom based on Mik's. Im using the 131 sbc kernel and i could not be happier. I also run setcpu for a screen off profile.
There are many different ways to conserve battery do a search. I believe HTC admits we should only get like 6 hours use. Try different kernals and see what works best, but give each one a couple charging cycles before deciding. The setup im using is great but peoples phones react differently.
Thanks for the input guys. I have been searching but i wanted some direct input.
Do you guys use app killers/memory managers too?I was using auto memory manager, but decided it was having little or no benefit at the cost of occassionally having to reload the UI.
Also what does SBC stand for?
Thanks everyone

I do not use anything but set cpu. Do a search for sbc theres a thread that gives all the explanation of different kernal terminology but im not sure exactly where it is
Ok cool, yea i looked it up last night and figured out what things like SBC and Havs are.
So what kind of battery life are you guys getting?
What kernel are u using with setcpu? you cant use that with stock kernel right?

You can, you just can't overclock on the stock kernel.
Kernel:
Netarchy 4.3.1 cfs-havs-sbc
Set CPU:
Screen off - 245 min 576 max
Screen on - 998 max 245 min (conservative)
Juice Defender:
Data turns off when screens off, reneables after unlock only. Enables every hour for 3 minutes to check email and such.
Task Manager: Quick system info task killer widget (only when I need to free memory for a heavy game)
Been listening to radio.com app over Bluetooth headphones while connected to wifi for 3.5 hours. Down to 76% from full charge.
Normal daily use for me is 200 texts, 50 or so emails, hour of calls, 2 hours of web, and at least 30 minutes of games. I take the phone off the charger at 7:30am and I can go till midnight no problem.
Friday I did a reboot at 10:50 am from a full charge and at midnight I was at 62% with a little lighter usage than listed above.
Thanks, sounds like the two most used kernels are netarchy and SBC. Any other good ones?

Welcome to the scene. Sorry for the smartass comment, literally just read the sprint echo announcement and had some anger to get out. Try mikfroyo with either launcher pro or adw ex for serious speed and smoothness. I prefer launcher pro for the sense like widgets without the sense like lag.

Unfortunately, there are no definitives, and if you aren't getting good battery life with the stock kernel with warm2.2, you might want to start looking at some battery tweaks.
There is a thread over in the Evo 4g General forum, the title is "2.2 ultimate kernel review :: Updated 11/6/10" and the OP is skydeaner. His site also has one of the battery "fixes" if its not holding a charge correctly.
Unfortunately, I can't link to it, since I'm still a newbie poster, but, some of the higher rated ones are Kings #11, and the new Net 4.2 kernels.

Im having good luck so far with Nets 4.2.1 CFS more aggressive smartass universal.
There were a lot of people complaining about the awake time of the 4.2 build, so Net tried to tweak the 4.2.1 to have the great sleep time of 42 with the great awake time of 4.1.9
I havent had the phone awake alot today but with light use I have gone from 100% at 8 am to..... 75% at 10:30pm This was no browsing or games, just phone for about 5-10 minutes and maybe 5 minutes of texting only 1.25 hrs awake time total so far.... so very light use today. But ive NEVER had the phone stay 75-80% inot the evening.
I REALLY hope the awake performance is as good as the sleep performance. We'll see how it does tomorrow under some stress.

Just for a baseline, I just put my phone back to root to take it back, I've lost 50% over about 26 hours of moderate texting and usage with just JuiceDefender running.
I have Kings #11 and my battery blows. I drain 25% in less than an hour with moderate use. This is off topic but when you enable your 4G does it automatically turn off on you. I think my 4G is broken and just want to know. I may need to reflash it.
im runnin it with stock kernal and i have no complaints. I just took a screenshot showing like 43% left off charger for 14 hours and talk time was like 1hour and 23 mins. Plus iv used it to play mabey half hour of games and half dozen text. Il see if i can get the ss posted.

Sent from my PC36100 using XDA App
I've been reading around the forums in different threads and Man there is a lot to catch up on since I've always been an Epic 4g owner and not an Evo 4g owner. I've found a few threads about battery life and so far have installed 4 roms to test briefly battery life and none are giving me the same as my epic or close to it which was 0-2% drop an hour when Idle.(Sitting on my desk on 3g or wifi) Gone through cm7, Miui(Currently on) and 2 of the new sense 3.0-3.5 roms (Energy and nocturnal)
Kernel currently Tiamat 3.3.7 and I've tried the latest one 4.0.1 or something.
So far i've found the Vipermod kernel undervolt tweak, V6supercharger Option 7 (used before), 3g turbo charge script, and also applying gps fix from Miui thread.
Any suggestions on other tweaks I should flash ? Is myns tweak out dated or needed from this thread? http://www.xda-developers.com/android/tweaks-for-superb-battery-life-in-evo/
I always freeze DRM but with the epic I found other processes starting with SNS to freeze, are these not on the Evo4g? or are they called something different? Also I don't see a System Update process that I used to see on the Epic and would freeze.
Calibrated method I use is charging to 100 percent and just using the Battery Calibrate app in the market. Its the first one that comes up when you search.
Any rom suggestions that I should flash to get better battery life? I need to use my phone for pleasure and work so everything needs to work except 4g and video recoding 720p. I need everything else operational.
Also any suggestions on other battery saving techniques would be greatly appreciated. I've got plenty experience with the Epic 4g but the evo 4g is so old school i feel like this device loves to eat battery way more than the epic when being used and when not being used.
FYI i have a moderate to heavy user.
EDIT: for those who could gain from this post, I'm going to be following Carhaulers recommended settings. Hopefully i get better battery life and everything runs smooth.
GB-evo-deck 1.3d or MIUI's latest creation
Tiamat v3.3.7-SBC aka the "LEE" kernel
Under Clocked @ 128/499MHz <<128/499MHz IS the new 245/998MHz>>
Under Volted @ -100mV total w/ IncrediControl
Results SO far and a Sense Question.
So as an answer to my own Question i've added the following items in my signature for my Evo 4g and I have no idea how this phone is operating so well at 128 HZ - 499HZ but wow its working smoothly. Battery is pretty sweet also. Still calibrating, drained it completely today and am charging right now to full with it powered off. Only time will tell.
I've had the phone off the charger for roughly 20 hours with no use for 50 percent of the time and the other 50 percent I was playing pandora, browsing xda/engadget, and playing 30-minutes to an hour of games. Not bad so far. Its better than it was before. Now this goes to saying i am uving like a mofo and underclocking.
New Question for those who read this, Is there a Sense Rom that will give equal if not better battery than what i'm seeing so far? and does COD tweaks work with sense roms?
MikG 2.61 rom works great and has great battery. Might want to try out Chopsuey 9.2.7 kernel with it as well.

Well im not so sure about this but.
Isnt the epic still on froyo?
Cause in my experience all the old froyo roms for the evo gave me way better battery life than the gingerbread roms.
I could get like 24-30 hours on myns warmtwopointtwo rom. Which is froyo. I only get anywhere from 12-15 hours on all the new gb roms.

The Epic's up to Gingerbread now, as of early November (finally). Froyo ROMs did get excellent battery life... I did like Myn's Warm TwoPointTwo, paired with a Netarchy SBC kernel... An incredible combination. I can still match that on Gingerbread, but Warm was awesome.

I have had exceptional battery life using BEASTMod.
Just my opinion
they are all good imo, im currently using gingersnap rom, has the faux kernel and i get over 20 hours of some what heavy use, and so it went with juggernaut, beast mod, and bombardier.
but the faux kernel has proved to be smoother and more efficient imo, perhaps slightly better battery.
hope i could help
I like Juggernaut + Bullet.
I am trying to make the most of my battery by:
-underclocking to 384-16xx
-turning on Battery Saver
-running Juice Defender
Anyone know how to undervolt on Bullet?
I am a heavy battery user. I use my phone all day constantly on Netflix (through Wifi) and listening to music with web surfing. I get about 16 hours on it everyday and come home with 4%-30%. It is very odd on why my battery percentage is such a big range. Screen is on like half the day. I really can not complain about this battery.
I am trying to figure out the best setting on tuner pro for dewizzed 2.0. I am only getting like 6 to 8 hours on my phone. When I've seen others get close to 24 with light to moderate use. The rom is Dewizzed 2.0, and I know the some people have the same rom while using tuner pro. I would ask the dev in the devolpment section, but I don't have permissions to do so.

I noticed a bit of lag when I first flashed Beast Mod w/Synergy. Try this before you flash, it worked for me and my phone is buttery smooth. Boot into recovery wipe cache 3 times, wipe dalvik 3 times. Then go into advanced, then mounts and storage. Format system. Flash synergy, then fix permissions. Reboot, enjoy. Also Im running zepplinrox's V6 supercharger script. That helps out with smoothness too!

I would be interested in this as well. Currently I am Rooted and have tried a few ROM's but haven't found one yet that doesn't have some bug or another. {Granted, I haven't tried them all} Tried one ROM that really distorted my custom made Wallpapers, which is a big deal to me. So... yes, any info on a better battery life Kernel would be welcome.
Currently I am not a "heavy user" on the phone. Talk - Text - You Tube occasionally... that's it. Constantly looking for better ways to improve this already amazing phone.
Eugenes kernel has given me great battery life. Either get down with Eugene's Macnut ROM which already has it or search for it under the general section under the bounty thread for Eugene. Its in page....58?
Keep in mind that the "beta" kernel does not have bln support but works just fine so long as you use the lionheart governor.
If you can't find the bounty thread then I'm sorry for you.
Synergy kernel has been awesome on battery for many.

How you use your phone determines the best way to get the best battery life. Basically there are two ways to save battery: cutting power when not in use and delivering less power to the processors.
If you use your phone intermittently throughout the day for texts or calls, you'll get the best battery results from kernels/ROMs/apps that cut unnecessary functions when you're not using the phone. For example, juice defender cuts your wifi and mobile data when your screen is off and reactivates it every 15min (can be configured otherwise) to check for notifications. Darkside's Digital Warfare utilizes something called "deep sleep" which actually completely turns off your processors when the screen is off, but keeps the basic cell radio on so if you receive a text/phone call it will wake up the processor. These functions have the largest and safest impact on battery life.
If you're constantly using your phone and you want better battery life, you basically only have one option: undervolting. This is essentially supplying less power to your processors, which can be done through system tuner. It's not a free ticket, however; if you undervolt too low then at higher frequencies (playing games, etc.) your processor will become unstable and your phone will randomly reboot. If you encounter this, then don't undervolt that much and up the voltage to the last safe level. Just for reference, undervolting by 50mV is usually considered safe and undervolting past 100mV usually results in boot loops. But how far you can actually undervolt depends on your individual phone hardware, there's no universal answer. Make sure to not set your undervolt settings to set at boot until you find a stable voltage. Otherwise, you'll be forced to restore a nandroid if you encounter a bootloop.
TL;DR
If your phone already lasts a day and you want it to last 2-3 days, look into ROMs/kernels/apps that cut unnecessary functions when not in use. Most effective way to extend battery.
If your phone lasts 8 hours and you want it to last a day because you're a heavy user, look into undervolting with system tuner.

my phone used in 24h, very good
I'm using juggs. 5.0 with a DSX kernel. I've been getting about 11-12 hours with decent use.

stock rom. Just download a battery manager from the Market.
Right. So a friend of my friend made me root his phone a while back and I threw mikg 2.52 on it and all was good. Now the guy contacted me today and said his battery life was in the crapper and wants me to change it to something more battery life favored since he isn't by a charger for a long time throughout the day. And since I have been using the new ics roms and jumping back and forth often I don't really know what to give him now.
So what's your opinions? I need something stable as a rock and best battery possible. I need this to last him a while since I almost never see this guy... Haha
P.s. I know people hate these kind of post. Just bear with me here because I'm meeting this guy tomorrow morning and have to know what I should flash for him. Also no aosp please.

You could have him try the one in your sig. It gave me great battery life when I used it, but as always, YMMV. You really have to try them out and see which gives the best battery life for you.
Also could try apps like Juice Defender or similar that aim to optimize battery life.
The only rom i can think of that ive used that doesnt drain your battery would be cm7 or decks gb. Ive used it myself & ive seen good battery life even with my cpu overclocked.
Does it work on viper rom? V2 redline? Thanks! Please let me know
I have the latest MIUI by Swiper, and since 2.2.6, my battery life has been phenomenal with Tiamat kernel 4.1.0, Car-O-Dope tweaks and Vipermod -50.
Phenomenal as in comes off the charger at 6AM and when I get home from work at 5, it's still over 80%

I can confirm this.. ALthough I use 2.3.2 b1 and 3.3.7 sbc kernel as I had some reboot issues with 4.1.0 but yeah.. I'm still at 100 percent at 11:00 am (work at 8).. come home and still at 90. go to bed and hit the charger right above 80. It's unreal.. I consider myself a heavy user too... email,sms,phone calls... etc.
I am currently using Swiper's 2.3.2 b1 with 3.3.7 sbc and have not run into any issues. Battery life is great with this combination for me. Also, keep in mind that I do not run many widgets except an calendar agenda widget.
Myn's Warm series rom's always gave me the best battery life.
i use energy sense 3.5 rom with anthrax kernel. iv had decent battery life w it. about 14 hours or so w moderate use and in and out of roam looking for signal. from what iv read CM7 and MIUI roms are much better with battery life than sense roms. they also seem to be more customizable.

80% at night with heavy use throughout the entire day? I can't believe that. Screenshot? If someone else can validate this, I might try the rom with LEE kernel.

He did mention no AOSP (although AOSP really does have the best battery life IMHO)
Koni's Elite Series III combined with netarchy-toastmod HAVS-less had decent battery life, only issue is that was a Froyo build.
kluster1999: I agree, pic would be awesome.
I don't mean to sound rude, but different ROM and kernel combinations can only make so much of a difference. I'm skeptical of claims of amazing battery life with heavy usage because in the end, the battery is still the same size and the large screen still draws a lot of power.
Been having great Battery life with "The Exress" using" Lionfish more" kernnal and smurfed out....
