Can I ask what kind of profile some of you guys are using to get these batter numbers?

I have mine set to "conservative" 11500 max 245 min, and screen off to 245 max/min, and my battery went down 10 percent in 6 minutes while browsing through my phon.e
[EVO 4G Android Development] barnacles10:
I run 884 max 245 min in setcpu, no profiles, conservative and easily get through the day. Underclock!? Whatt!? haha but it makes a difference on battery and barely any difference on the tasks I perform.
[EVO 4G Android Development] Vandam500:
Seriously though you barely use your phone. No way you can get that much time and still that kind of battery left over. I want to see a battery info screen shot although I am already pretty sure "Phone Idle" is going to be one of the highest %'s there.
[EVO 4G Android Development] th3taman:
No offense, but I'm assuming you know that you flashed in the wrong order? Flash the ROM, then the kernel.

Still testing out #4. Have high hopes! :D
[EVO 4G Android Development] andrewmc42:
There you go, provided I uploaded correctly.

I rebooted the phone this morning, I will update after next charge.
[EVO 4G Android Development] yamaford:
Yep. The Rom overwrights The kernel. I flashed fresh then 4 and rremoved set CPU. I tried the paid version of jd but it freezes on overlooking. Got it all themed out again and running smooth on the default settings. Weatherbug. Is running good and my wheels keep spinning when I stop. (dub lwp) . Yes I know it kills battery but I bought a smartphone to use. Bell I probably only talk on it once or twice a day. Now if somebody would black out swype. Again I'd be complete.
[EVO 4G Android Development] Just_s:
I've been running stable at 1.19 for about 10 days. 1.22 lags then eventually crashes. If it's any consolation, I don't really see that much lift on 1.19 versus 1.15. I did see some speed at 1.22, but even "grooming"it over time my rig just doesn't seem to handle 1.22 well. I'm after battery anyway, so 1.19 is plenty. :)
[EVO 4G Android Development] wsantiagow:
These screenshots dont mean a thing. You rebooted!

Will wait for you to redeem yourself.

[EVO 4G Android Development] Tyzing:
I'm sorry I meant my 2000mah battery. Same size as the regular
[EVO 4G Android Development] Jsimon9633:
1.19 is my wall but really I think that's great enough my phone runs great now! Live this kernel

Lobe fusion froyo 2.5 with it even more
[EVO 4G Android Development] akarol:
Where did you get that?! Do you really notice a significant difference with that battery over the stock one?!
[EVO 4G Android Development] Tyzing:
It's the old Hero battery's that fit. I'm a heavy user so it's great to have just have a spare. I do get better battery life. Normally on #4 I would get 13 hours or so and now I'll get 22-24 hours of usage. It only cost me like $10 too so it was worth it...but the reviews are not great so I'm thinking it may be a crap shoot with these things.
[EVO 4G Android Development] wsantiagow:
Here is my battery life with Calkulin's EViO2 V1.02

BFS #4

FPS: 54 4-5 Dev

Quad: 1475

LinPack 38 ave.

SetCPU: 1152 interactive 1 Profile set "screen off 384/384
[EVO 4G Android Development] akarol:
Not impressed. I recommend lowering your Screen Off clocks to 245/384 'conservative'.
[EVO 4G Android Development] wsantiagow:
I did not post it trying to impress anyone. Posted it for comparisons and gauging with different setups.

Tried that but my phone was having a hard time coming out of sleep for some reason, so i raised it.

BTW what are you getting for battery life?
[EVO 4G Android Development] akarol:
Well, with moderate/heavy use, I'm atound 24-26 hours.

Light use (this weekend was pretty light, I just passed the 30 hours mark. I'll take some pictures next time I do it as I've been restarting the phone a lot these days trying to get the dreaded 1.40 PRI.
[EVO 4G Android Development] DanBergundy:
Finally made the swtich! I left CM6 + Snap for Stock 2.2 deodexed + Kingx#4!

I have been one of those users getting horrible battery life (8-10 hours max with moderate usage)

I just charged up to 100%, we will see how it goes!

First impressions:

Performance is UNREAL. I thought CM6 was snappy, this is just as good if not better. Blazing fast.

I did notice one thing, using setcpu works well until I set profiles (I only have tempurature, screen off, and low battery profile). If I set profiles the phone gets really choppy. I am guessing it is related to screen off. It wouldn't come out of it until I restarted with profiles off. I had 245-384 or w/e which has always worked on other roms.
[EVO 4G Android Development] rockky:
Wheredja get that bro. Thought 1750 was highest same-size battery out there.
[EVO 4G Android Development] DanBergundy:
I saw mention of an 1800 before, highest I've heard of.
[EVO 4G Android Development] wsantiagow:
Yes screenshots would be helpful to others along with your rig's setup.
[EVO 4G Android Development] Djay45:
I dunno that's pretty impressive to me. Over 6.5 hours of awake time out of 18 sounds pretty good and still at 20 ish% battery
[EVO 4G Android Development] MikeOD:
I just wanted to post how thrilled I am with this kernel. My phone is fast, everything functions properly, and I've been off the charger for 11 hours with moderate text messaging, email, took a few pictures, and browsed XDA for a bit...and the battery is still above 70%.

Running kernel #7 and overclocking to 1152 on demand...anything faster crashes immediately, but the phone is rock solid stable at this speed...it's a 0002 Nova panel phone, if that matters.

Thank you for making this.
[EVO 4G Android Development] jasongthang:
I'm still having issues with lag when waking the phone from "screen off". Even with the "screen off" profile set to 115200 mhz and "performance", it still takes a good 20 seconds before I can start using the phone.

I think I might just uninstall setcpu altogether. Is anyone else really having lag when turning the screen on?
[EVO 4G Android Development] Biofall:
Make the screen off 245/245 batterysave. Putting screen off on performance defeats the purpose
[EVO 4G Android Development] Biofall:
Either you have a very different concept of moderate/heavy use, or your phone is hooked up to a car battery. Just saying.

Lol I've become the biggest anti-false battery claims guy. Could you do me and the others here a favor and describe what that usage entails?
[EVO 4G Android Development] infamousjax:
Is #7 getting better battery life than #4? I'm testing now, but havn't seen much difference.
[EVO 4G Android Development] jasongthang:
well uh.... 3 text messages, 1 internet search for clay aiken lyrics, 3 10-minute phone calls, and i sent 4 tweets

lol
[EVO 4G Android Development] Biofall:
Haha well now that I said something the answer probably will be something like this.. I barely used my phone today, since I was at school, and I lost 20 percent with the phone basically sleeping, and have lost 20 percent more since school was out. I think it may be this juice defender I just installed cause this seems worse than earlier.

EDIT: Dammit I just looked and my phone hasn't slept all day... I wonder what's causing it
[EVO 4G Android Development] pongoface:
LAG FIX

Here is the lag fix for BFS kernel #4 for the bobos that can not figure it out. I am tired of seeing posts about it. Not sure if it is the kernel or the setcpu. Okay get ready not that hard. Unfortunately this must be performed prior to reboot or battery swap.

1. Uninstall setcpu

2. Reboot your phone

3. Install setcpu and enable profiles

4. Screen off 245/245 powersave

5. All other profiles your choice, mine 245/1036 slight oc

This works everytime. I get killer battery life. Mind you that I kill seidio's with no problem because I hammer on my Evo. When I use my phone as normal I can get 24hrs no problem on a stock battery.

That was easy. You've got questions I've got answers!!!!
[EVO 4G Android Development] pongoface:
lol not juice defender, system panel will tell you that. But, ultimate juice sucks in comparison to setcpu in power management. Juice defender does save battery life when shutting off 3g with screen off as long as you have setcpu controlling the cpu.
[EVO 4G Android Development] BAleR:
I get the lag, every once in a while it will just suddenly be reeeaal laggy, like the phone cant jump from 245mhz or a real low speed. I have never installed setcpu so i think its just something wrong with the bfs.code

This has happend on backed snack1.4 and froyofusion1.5 seems to happen no matter what rom im using, aslong as im using #4
[EVO 4G Android Development] Biofall:
Yeah I've been using setcpu in conjunction with juice. It's not juice defender.. using system panel a long time ago I slowly killed all my stuff and let it come back to see what kept the phone awake, and all the stuff that didn't I had marked.. Now when only the marked ones are running I still have no sleep... WTF
[EVO 4G Android Development] pongoface:
Yes, noticed it as well. But by installing setcpu with my method eliminates the lag. It is a pain in the ass when I am doing a battery swap or flashing something new. But I love the balance of power and battery with this kernel. So I am living with the less of 2 evils.

Yes there is something different with bfs #4 and earlier versions with the interaction of the scaling and the handshaking with setcpu.
[EVO 4G Android Development] pongoface:
You could try wiping and flashing another kernel to see if that solves your problem. Then flash back afterwards. I have never had a non sleeping issue. The only thing I can think of is that you have an app allowed through juice for 3g use that is running non stop.

Download Task Manager by houmiak from market. Open that up and select menu and the sort by cpu usage. It will definitely tell you what is eating away at you and your EVO lol
[EVO 4G Android Development] anthony1487:
Can someone please help me out? I have been trying this Kernel since the very first one and I have yet to see an improvement on my battery life. I'm currently running BFS #4. I hear all this talk about 24+ hours and I can't even get 8 off of my phone. Is setCPU necessary to achieve these numbers or is my 7 1/2 normal? I do use the phone a lot. Mainly texting, few internet searches (2-3), a couple short calls, and quite a few Wordfeud plays. Just unplugging off the charger loses about 2-3%. Thanks for any help. King thanks for the hard work, I really want this to work for me to send a donation your way.
[EVO 4G Android Development] Biofall:
Well for starters, the 24 hours of moderate/heavy usage isn't feasible, so there's that. I've been trying to get it across for people to stop posting that without proof...

Anyway, there are probably a hundred battery threads on here, if you go to the evo fourm and type battery thread, you'll see a ton of setcpu and juice defender and other stuff. If no one responds with a bunch of info or if you still need help pm me
[EVO 4G Android Development] akarol:
So, I decided to disable profiles on my SetCPU just for the heck of it. Anyone here believe that SetCPU really doesn't account for that much battery life saved?!

For some reason, some times when I boot, it is laggy as hell. I am required to reboot the phone to get the speed I want. It only happens sporadically. I believe SetCPU might be the culprit for some reason. I guess time will tell.
[EVO 4G Android Development] anthony1487:
Alright perfect, I'll look into it now. Shoot I'll be happy with 10 hours of usage. But basically the 7 1/2 - 8 hours is normal until you use the Kernel in conjunction with setCPU or Juice Defender? I just want to make sure it isn't my batter or some roque app thats eating away at the battery.
[EVO 4G Android Development] willy900wonka:
I learned from the hero that setcpu uses more resources than the benefit I get from it, to me. So I use it to test settings, then I remove it. I'm currently using oc widget. Set to conservative with oc to 103... screen of is set to246-246. Setcpu is un installed. I used the phone for 12 hours, light stuff about 5 calls, 20 some texts, a 5 minute qik video call. Maybe 20 minutes total web browsing. A light day. Had 59% left when I plugged it in. Juice plotter predicted about some crazy amount of time, so I'm testing it.

The oc widget let's me specify the speeds I want and meets my simple needs. Try conservative without setcpu. Oh yeah I'm glad to help if this helps, for the heck of it. Lol
[EVO 4G Android Development] Biofall:
Yeah what you said is correct, but it GREATLY varies from phone to phone, battery to battery, usage to usage, app to app. Idle time isn't even comparable. That's why to me, battery talk is dumb, but it will continue. All we can do is suggest things to make it better

I'm trying to find it, but I typed up a good little couple of things to do, but I can't find it in the forums. It was pretty good lol
[EVO 4G Android Development] anthony1487:
Thanks!

Yeah, I'm not expecting drastic results, just a couple hours more of productivity on my phone would be enough. If you happen to find the link to the post you were referring to please PM me with it. Thank for the response though.

Great, I'm actually trying this now. Set the screen off setting to 245760/245760 and screen on to 245760/1036800 max is that correct? I'll keep everyone posted on the results so others can use them. Thank you for the help!
[EVO 4G Android Development] houseofbugs:
I am just curious as what is the advantage of the BFS over the CFS kernel? If i want the best battery life what one should I use?
[EVO 4G Android Development] lucidvtec:
runnin Evio 1.1 with King's BFS #4 kernel....flashed per kings instructions..using clockworkmod

i did the flash on fully charged "stock" battery...wiped battery stats aswell

pretty freakin IMPRESSED

i made a few phone calls...bout 20 txts....5 pic msgs....checkin Facebook every half hour..lol.............email once......calculator widget a few times....camera for a couple photos

i'm a AC tech in AZ so the phone gets pretty hot while i'm working

the only thing that gets me is the first 30% of the battery seems to drop really fast then it levels out kinda.....i ordered another stock battery and a seido one as well....i did the first couple of charges the right way...maybe i got a weirdo batt

anywho...here is a couple pix

[EVO 4G Android Development] rizzoads:
How should one go about proving that? I've never really posted regarding battery stats, so I don't know the protocol.

I'm asking because I can EASILY get more than 24 hours off a single charge. If I can provide some kind of proof that might be of service to others, I'd love to do that. I've been off the charger with *my* normal usage for 14 hours today, and I have 68% battery remaining. Probably 10 minutes of voice, 20-30 text messages, sent probably 6 or 7 emails, received 40 or 50 emails, did some browsing for about 15 minutes... GPS and WiFi on all day, bluetooth and 4G off.

Evio 1.1 with BFS #4. I also keep it underclocked to 691, and 245 when the screen is off.
[EVO 4G Android Development] Biofall:
Ah, well I mean stuff like screens of your battery usage page showing phone awake vs sleep time, a battery graph, and usage like you just posted. Except for the gps, most people could get that usage. That's what we'd call light usage, due to the limited amount of time actually interacting with the phone. I'd say you have about within 10 percent either way of what others would have, myself included.
[EVO 4G Android Development] jasongthang:
not to get too off-topic,

I remember when I first got the phone. The first day at work I barely touched it, and when i got home, messed with it for an hour or so. Before I went to bed, I hooked it up to a charger and it was only down to ~70%. I was so excited, thinking "what are those guys on the boards talking about, this phone's battery life is amazing!"

But now that I actually use the phone, I'm starting to agree with those guys. But I still don't think the battery life on this phone is THAT bad. But it does seem that everyone's phone acts differently.

I'd say, make it a rule, before you post your AMAZING battery story, make sure you have a screenshot to back it up.
[EVO 4G Android Development] rizzoads:
Gotcha. I've never done those kinds of things before, so I'll do some reading. Once I figure out how to take screenshots and graph usage, etc, I'll post it somewhere. I think you're right that I have light usage. I usually use my phone a lot more on the weekends, but even then I rarely use more than 50% in a full day.

All I can say is thanks to the developers for everything! I couldn't get through a day with the stock kernel and ROM.
[EVO 4G Android Development] Biofall:
You're rooted, so download shootme from the market, really simple screenshot application :D

Download juice plotter or battery graph for the battery data off the market.

Does this kernel restrict HDMI out at all?
[EVO 4G Android Development] Biofall:
So I'm always recommending battery tips for people, so I decided to just save a word document I could copy/paste from lol

Here it is, and I undoubtedly forgot stuff, bear with me.

My tips for good battery life:

1.	Turn off all radios when not in use (gps, Bluetooth, wifi, data, 4g) using a widget like the default HTC power widget or switchpro from the market.

2.	Use SetCPU in compliance with whatever your custom kernel allows. This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/

Profiles from SetCPU should usually involve these for battery life optimization:

a.	Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent

b.	A temperature greater than “X”

c.	General power related profiles that lower cpu speed at lower battery levels

3.	Juice Defender is my new fav, explanations on their page, search it on the market for free, or upgrade for more features.

4.	I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.

5.	Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data

6.	Set your screen timeout to something that fits you so that your phone doesn’t stay on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.

7.	Everyone has that issue where the first ten percent go the fastest. This is due to two things. One is that these types of batteries stop charging once they get to 100% to prevent damage, and begin charging again at 90%. This means that you could potentially unplug your seemingly fully charged phone at 90% actual charge. The second is number 8.

8.	Use the trick described in this thread, it works: http://xdaforums.com/showthread.php?t=701567

My idea behind how often you should do it is once a month, if you flash a new ROM, or if you stop noticing the benefits.

9.	Task killers used to be the shiz, but in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop :P

I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.

Hope it helps everybody!

[EVO 4G Android Development] tlvb25:
Wow...I can immediately see how much better the over clock widget manages the overclocking ranges. I do remember flipzmode explained how the overclock widget is much better at using very few resources and at the same time managing the overclock.

I Used all the settings that you suggested and I followed the install and setting of CPU then installed it, then installing OverClock Widget.

Things I'm noticing:

1) Much better battery life

2) It's very stable at switching the frequency ranges and its not

as sporadic like SetCpu.

3) It does an amazing job of distributing the frequencies.

4) My phone is running much smoother due to the efficient handling of OverClock Widget

I'm freaking loving it thank you so much for bringing this info to this post!!!!
[EVO 4G Android Development] nYdGeo:
Hmm, with my current settings there is a bit of lag, but at the worst its maybe one second. I don't mind being patient on occasion to save the juice, but I can completely understand having an issue with 10-seconds.

I'm not sure what might be causing that, but we might both try upping the screen-off max speed a bit as suggested. I'm going to up mine from 245/384MHz to 245/499MHz, and see if I detect any reduction in that lag time.
[EVO 4G Android Development] cowfodder:
12 hours use. At 16% battery. Would show screens but there are a few reboot in there from flashing a theme and trying to get the 1.4 pri.

From my Evo to your eyeballs.
[EVO 4G Android Development] dallashigh:
BFS and CFS refer to the scheduler, which decides how much CPU time to give each process. Battery is not affected by the scheduler. It only affects performance of apps.
[EVO 4G Android Development] Onelife511:
Wow just switched from setcpu to overlook. Running alot better. Just got my best quadrant score. I'm not here to flame the either. I could not tell u how battery is going to go but performance is great. What type of govener does this app use? The kernels default?
[EVO 4G Android Development] juancaperez2000:
Try set up both at same frequency 499/499 that how im running my phone now look that you remove the lagy issue

[EVO 4G Android Development] wings9130:
I don't really see any improvement in battery life with this kernel. I thought there was much less voltage use thus better battery. Using setcpu on demand screen on 998/245 screen off 245/384 and when my battery goes under 20% it goes down to around 750/245. My battery is good when the phone isnt being used but dies fast as usual when I use it...is there any way to save battery while using this phone? I am running damage 3.5
