Interactive governor with min and max frequency bars all the way down/up. The only profile I use is Screen Off, conservative governor, and freq bars all the way down.

What sort of Quadrant scores are you pulling with CM 6.1 RC1? I just installed it yesterday and hit a 1675 today. I haven't isntalled SetCPU yet. i am going to let it work it's magic for a few days and see what it can do.

Just ran it and got a 1417. I've never been obsessed with benchmarks, so it doesn't really bother me. The phone is fast as ****, and that's all that matters to me.

I plan to test the battery life tomorrow at work. I have been mostly at home this weekend so I have had a charger around.

I was also having amaaazing battery life with this kernal, I am in love and am just waiting the days till 6.1.1 comese out with our hdmi and 4g support!!!!
Im gonna check out that bfs kernal from bnice now, if it helps make it better than ooohh myyy.

I'm hesitant to try anything else with results like this. If it isn't broke...

My question is how stable is it? And you didn't underclock it at all except for screen off? I seem to be getting worse battery life than I did with Fresh but CM Evo always seemed to have a brighter screen than fresh which is what I attribute that to. I can't go back to Sense right now though. Loving CM6.1.

I agree on the battery life being great....

What do you mean by "how stable?" Also, make sure you wipe your battery stats and let the battery drain all the way. You can control your brightness by changing it... I leave mine on auto-brightness, which is actually a battery hog compared to stable brightness.

By how stable I mean does it crash or randomly reboot? CM6 doesn't ever do that to me unless I use SetCPU so I want to make sure that doesnt happen with your settings. Good call on the battery drain and battery stats. Forgot to do that. So wait, leaving it on a stable brightness setting uses less battery life than auto? Are you talking about half way up the scale or full blast?

I never get any random crashes or anything. The stock kernel doesn't OC enough to cause stability issues there.
A stable brightness of like 50% uses less battery than auto because it isn't constantly checking what the brightness should be then adjusting it. Not sure about full-power, but I'd assume it is a little more wasteful than auto.

Good point on the brightness. Ok so I set 50% brightness and screen off to the lowest settings in SetCPU. Let's see if this gives better battery life. Aside from the dialer being slow when I recieve a phone call (I hear the ringtone but the screen doesnt turn on for like 2-3 secs after it starts ringing) it actually seems faster with this interactive governor.

Interesting you're getting that kind of performance without using jd, impressive.
I got 36 hours recently, no setcpu, just ultimate juice and autostarts.

UltimateJuice always slowed my phone down to a crawl and burned though battery like crazy. Totally worthless.

i just cant see buying a 4G phone, paying an extra $10/month for it as well, and then put a rom on it that doesnt have 4G...... JMO

Well... 4G does nothing but suck battery like water in exchange for a marginal speed increase, and I'm usually almost always on wifi, which is faster than 4G by a mile. Sooooo....

well i stay on the move, i dont know of any statewide free wifi, so 3g/4g come in handy
plus faster is faster, that much less time to download files n such
and i have a 3500mah ext battery so mainly i have to charge at night when i sleep,so i keep 4g,bluetooth,GPS on all the time, and use my phone for the smartphone it is.......

Not everyone lives in a 4g area, why stay with a slower, less functional rom just so you can keep a 4g toggle available for the 4g you don't have?
I was actually taking a trip last weekend to an area with 4g so I switched roms to one that had 4g as an option, besides the fact that it is easy to switch roms in situations like that, I never ended up using the 4g.
Maybe its because the phone isn't glued to my hand, I use it to look up some things, play some games, make some phone calls, find addresses, but it isn't a permanent implant on my hand, I put it down when I'm not using it. Besides, it turns out that I'm on wifi 90% of the time, even at random places around the city.
I don't torrent with my phone, and I don't hang out downtown just to sit on a street corner and stream hd youtube or hulu. Apps like urbanspoon that I use a lot in new areas don't require heavy downloads.
Yes, the option would be better then not having the option, but CM will have 4g soon enough, for the 10 mins a month I might use it.

Show your battery record Genuinely

Hi guys,
After buying s2 i was worried about battery life. Because first two days it was like 12-14 hours of medium use.
But now its marathon :d
See some shots..

I thought i was getting good battery life with medium to heavy usage (27 hours) on Cognition 1.15 but that is exceptional, can you tell me your set up as to how you achieved this amount of battery life.
cheers

Tegrak's kernel and underclocked.
Frozen samsung apps. and brightness mostly 0% as i am fairly fine with the lowest brightness it doesn't hurt my eyes.
also one more thing, i am using overclocking upto 1300 as well and you will be surprised most people will tell you to go underclock to save battery but i didn't and i am just happy with 1.3 Ghz blazing speed.
Here's a shot of running.
REMOVED
Also i used camera for recording movie for about 50 minutes in 720P and 50+ photographs as well which is not mentioned in the above post. I will post once again when my battery will reach 1% because when its below 10% it drops really slow and allows me to use it more unlike when its full.

Sit it on a desk and stare at it. The average screen on time is 5 hrs. You can use that in a day or spread it across 3 days.

One more thing, i only recharge battery when its below 5% or mostly under 2% to full turning it off. And ofcourse this only first week of using the phone, hope it will increase a bit more by next week.
[Note: I personally believe plugging in and out of charger makes the phone battery drop faster]

You should blur out your IMEI number from the screenshot buddy.

What ROM are you using?
I usually have brightness set to auto, same as you all Samsung apps frozen, am not using Tegrak i don't believe it's compatible with Cognition ROM, are you using Juice Defender Ultimate or other apps,etc,etc, im on setcpu im 200 min - 800 max - on demand and screen off profile - 200 min - 500 max - consertivave - priority 100.
Seriously impressive all the same..

That is the best battery life ive ever seen on XDA for any type of smartphone never mind one like the GS2, did you use the Internet/Wi-Fi/GPS/Bluetooth,etc, much,do you have any widgets on your screen, push e-mail,etc, im amazed your getting that amount of time without using Juice defender or some other similar app.

Bluetooth yes for 10 minutes transfering some files.
Gps yes for around 1 hour (you can see that in pics atleast it shows usage for ndrive there)
wifi yes around 1 hour but its always on mostly (mostly used for market to download and test applications, gmailing and also some browsing)
3g or edge no i didn't use it.
Games yes i played like drag race etc.
widget yes, battery widget and the running app widget and live wallpapers.

Mine, I think there's a little (big) problem :
Considering the first 8 hours were during the night so I didn't touch my phone :
Running on VR2.1, many things push or so (like 15/30mins refresh) [mails, fb, twitter, news, weather, etc], and good modem (KG2) and CF-Root 4.1.
Any idea/advice please ?
A better rom maybe ?
Thanks in avance

The real secret to great battery life is to disable all the data connections and not use the phone. Since most people are pretty active with their phones, threads about stand-by time are pretty meaningless. Actually, with over a dozen battery life threads already running, you could say new battery life thread are pretty meaningless too.

Ok thats along the lines of what I thought it was. Thanks.
Didn't know it was possible to change it, illigal. Huh
But can some one tell me where it is shown so I can block it if I ever post some screen shots?

I'm on stock K2-CL. I used 3G just a bit today while in a restaurant, wifi is always on, but I normally sit in front of the computer most of the day, or use my tablet at home, so I do very light surfing - mostly while on the can.
I've not installed "app freezers", nor underclocked the processor, nor rooted or removed anything that isn't stock android. Not stopping tasks in the task manager. In the screenshot below, I did play around a bit on Google Earth for 15 min or so, I'm surprised not to see the android market in there because I feel that's what I used most. I use a live wallpaper that's fairly bright (moving clouds).
Brightness on auto - automatic gmail notifications, contact syncs etc.
I'm going to go on a big trip next week, where electricity will sometimes be optional. I do have that Samsung battery case thinggie coming the mail next week - and already have an external battery as well for emergencies, because this phone will die in an hour or two using the gps, or playing games, or doing serious web surfing - or a combination of those things. It runs very hot too if you use it constantly several hours (drove 500 kilometers last week, the phone was very very hot - seemed unhealthy).

If you hold the power button along with the home button it takes a screen shot.
Thought id say to make it easier for ya in future!

thanks a millions

Don't mind the n00b Here.
Found the IMEI number in the status tab of about phone.

About the battery consumption

Hello, I am a happy owner of the DHD.
It 'a great phone, but as you know, the only drawback is battery life.
I've tried several (few) ROM so far, and one with which I am slightly better is the RCMIX.
Now with this post does not go into details about what set, how to optimize (Sync off, energy saving displays, etc. ...) but I ask all your experience based on the ROM that you have installed:
1 - how to use the terminal?
2 - how long you last on a full charge and use it to do?
3 - What kind of ROM you use?
Thanks to all. I think it will be useful for someone like me, prefer a long battery life rather than three thousand graphicals functions

With normal usage (some SMS, about 30 minutes surfing and emailing during the day, 30 minutes music listening and wifi turned on all day) my Phone lives mostly a full working day. When i come home from work (mostly 8 to 9 hours) i still have 20 % left...

Battery life... it's been quite heavily documented on the DHD fora, but here we go:
1500mah is not enough for a huge screen, especially if you want to use the phone's capabilities. The versatility of this phone means you'll want to be browsing, doing emails, playing processor heavy games etc. Each to his own
So, limit the stuff you sync (mail/facebook, news, weather), or at least reduce the frequency. These things cause "partial wake locks", which stop the phone falling into a deep sleep, after which battery consumption is minimal. Watch out for wifi settings too. Search for BetterBatteryStats (by chamonix) on the Android Apps section of the xda forum for much more detail, and tips.
You should be able to get to the end of the day with a good ROM (eg Leedroid/Revolution - they are very popular, but the threads are immense, which makes looking for information difficult). These ROMs have over/underclocking built in (governors), and you can also undervolt (theoretically reduces consumption too).
Limit transitions, be reasonable with screen brightness etc.
And if all else fails, and you use the phone intensively and can't get to the end of the day, you could invest in a power pack (search Amazon for the New Trent 5000mah power pack, which costs less than €30)

my DHD lasts around 4 hrs continuous screen on, much longer screen off. IMO, LM based roms have the best battery life.
But you could always get cheap $3 batteries for the Desire HD off ebay.

Battery life on my DHD was very bad before i rooted it. I am now running RCMix3D Runny V1.3 and my battery has lasted over 30 hours with alot of use.

Your kernel? Radio? Ril?

with m0rbus called "normal usage" my phone lasts around 48h. using my rom and lordmod 7.2 cfs and my personal governor/undervolt settings.
edit: though this result is not really specific to MY miui rom. one should be able to achieve these results with that kernel and settings on every aosp rom.
edit2: with "my normal usage" it last around 24-30h. this includes gameing, emailing, testing settings for developing my rom, rebooting etc.

I've used alot of roms most of the sense ones seem to use about the same battery life better than stock (they get me through work stock needed charged at lunch) but for a week now I've been using miui I've been home about an hour played about 15 min of angry birds, watched a few min on youtube and surfed on xda for a bit and I just over 40% i think that's pretty good going.

Hi, I upgrade the ROM from the group Android Revolution, and my internet I put on 2G and work with WI-FI, GPS and SYNC ON. My battery life is working about 1,5 day.
Before I upgrade I use a Super-Wire patch from ARHD, I think this patch get this performace.
PS.: Sorry My English. I´m Brazilian.

I dunno guys.. I think all that is your subjective feeling and that ROM has no effect whatsoever on battery. Maybe small, but unnoticable. You never do things exactly the same or have battery charged exactly the same. In order to prove ROM has effect on battery usage you would have to make lab tests, i.e. make conditions the same. Moreover, if you look at the statistics of battery usage, it is clear that the most battery goes on SCREEN. And then GPS. Everything else is just a couple of %. All the talk of turning off wifi/3G to conserve power is simply not true. Just look at the statistics! Wifi takes like 2-3% of the power used, tops! The screen with it's 40%-70% is the problem, and there is no way to reduce that...

exactly....

You could always try to lower auto brightness levels by way of a flashable patch. I found that after doing this the screen was only using between 30-40% of the battery. Even so, it is the screen that always uses the majority of the battery. All the tips regarding decreasing battery by switching off syncing, wifi, widgets, etc are in my opinion a bit misleading. If you have a good radio and corresponding RIL then this will vastly reduce battery consumption whilst still being able to sync emails, widgets, etc with the wifi on. I recommend Radio_12.54.60.25_26.09.04.11_M2 and it's matching HTC-RIL 2.2.0160HM. I'm currently on Orange in the UK and this combo works best for me across several different ROMs.

Yes and no.
If you are using the device, you can limit transitions, underclock the processor (via a custom ROM), flash a patch to modify the brightness as mentioned below. That definitely will help reduce consumption while in use.
However, and this is not collected in the Battery Usage option in Settings, Partial Wakelocks are the main contributor to battery consumption. When the phone is inactive, it should be asleep as much as possible - applications like Phone, Mail, Latitude, alarms etc wake it up for either scheduled or ad-hoc events. If you install BetterBatteryStats you will see which processes are keeping your phone awake & hence in a higher state of battery consumption.
Oh, do NOT buy cheap ebay batteries. They lie about their capacity. The only battery which offers more capacity than the OEM one, is Mugen (search in the Accessories forum), it's 1500mah. That extra power could make the difference in making it to the end of the day, but it costs about $45 I think.

You think this behaviour is normal?
Keep in mind that my DHD are this morning on the deck, and only hotspot is active (with whom I connect from the notebook) and sync only 2 emails to connect every 15 minutes each

If I charge the phone before going to sleep to 100% and leave it on, in the morning the battery it at like 60-70% which IMHO is really too much. I have sync set to between 1-2 hour intervals depending on service, but over night I set phone data to OFF so it shouldn't matter, should it? Then why such consumption? I understand it over the day when I use it, but at night the display is off, data is off so what could cause this? It can't be syncing since the data is off....

Post your battery life results & which Governor/Scheduler combo you recommend

Happy New Year first to all.
Now what i would like to do with this thread is create a place were people can discuss about battery life and post screenshots of their battery life. Also talk about what settings you are using and what is your overall experience and what is the best screen on time you had so far.
What i like people to talk about is what kernel they use, what governor, if you are using a scheduler and if you are using any scripts to improve performance or smoothness when scrolling through screens. Also if people can provide there tricks and tips on how they get the best out of their battery might be beneficial for new users who just got their handset and looking for ways on how to get that extra juice from their battery
Over the last week i have been using Siyah kernel and i have to admit in the beginning i thought not much of the kernel. But after reading and learning regarding the Thunderbolt scripts (by Pikachu) and also that i could use the lulzactive app(by Tegrak) i was blown away by the smoothness and performance. Now if you are using scripts the app is not needed as far as i know(please someone correct me if i am wrong) but either how being able to use different apps or scripts to improve my phone even more it has left me speechless.
My average screen on time is about 4hrs and 30 minutes. That is over the duration of one day and a half. Before i used to use Savaged Zen governor and use to UnderVolt quite alot. But now after turning to Siyah kernel and trying out the lulzactive governor i am also again amazed by the battery performance.
Now different governors and different schedulers are dependent on what use you need them for. That i will not go into as there are other threads that explain all that in more detail. Please see here for more information:[REF][&Tweaks] Kernel Governors, Modules, I/O Schedulers & CPU Tweaks: Siyah & Others
My idea behind this thread is to keep in one place everything. Regarding settings, what scripts you use, what app you guys prefer either if it is Voltage Control, No Frills or SetCpu or if you recommend any other ones and what scripts are best to use if you do not like to use an app to control all your frequencies. What kernel you guys prefer and which one gives you best performance, or best battery life or even which one you guys has the best of both worlds. That is my aim for this thread..
Not to have wars in which one is best or not. Just a discussion on how people can improve or learn even on how to use scripts or how to get the most out of their battery and improve performance as well. Yes again i will say there are loads of threads but if you have one were each member can provide their experience someone might benefit from all this.
And as a pointer yes i know let's say my settings that i use might not work for someone else. But if we can give pointers and examples to others on how to start and they can use my one as a template say on how to improve their ones then why not i say.
Anyway guys i know for some they might not like this thread and for some they might say it is not worth the hassle. But if you can give ideas on how to improve the thread and please first see my idea and logic were i want to go with this then please feel free to input and give me your opinions in improving it.
Thank you to all and have a very Happy New Year.
Credits to all the devs and specially the creators of all the kernels out there who make my phone into the beast it is now. Respect to all XDA members and this is one community worth being a member off.

Above you have screenshots of my battery life using Siyah kernel 2.6.3 and Thunderbolt Scripts 2.3.2
As you can see for me it is pretty amazing and the results are brilliant. Now on Siyah 2.6.4 and Thunderbolt scripts 2.3.3.
Also using Voltage Control and undervolting and using scheduler SIO and governor Lulzactive for now. Testing the new kernel and same governor with updated scripts to see how battery goes. I shall post different screenshots for different governors in due course.
Cheers

I will be keeping a close eye on this thread thanks!

Thanks mate..Not only doing this regarding to see battery life with different kernels i am also doing this to learn from others on how to use scripts and what they do to get the best out of there handset. Thank you

My battery life before...stock with speedmod
NOW...... check rom and speedmod
tried everything NO solution yet........
you may say i have more apps running now but... generally the battery life is really poor now..you see i have the ANDROID OS virus

install BBS and find out what keeps your phone awake and causes the battery drain and then try and unistall it.

Tried and failed. No luck.... Can't find the culprit. Keeping wifi on did drain more battery but it was not the only culprit.

Can not help you then buddy. The only thing i would suggest is try and make wifi to go off when screen is off. You can set that up when you go into settings - wifi and network and then wifi settings press menu button click on advanced and there you will find sleep policy and try switching it to when screen is off for wifi to sleep come out and reboot

Believe me I've tried everything I've tested every ROM and kernel combo and I even purchased juice defender ULTIMATE (all radio off when screen is off) but couldn't get rid of the Android bug. Hope ics built will fix it. I have learnt to live with poorer battery life.

Give Siyah a go and use Voltage Control to control the cpu clock and try and undervolt a bit. Use Lulzactive governor and see how you go. Also try SIO scheduler...Let me know how you get on

I took these screenshots few days ago using SensatioN 3.0 with Siyah 2.5.something.. I'm now on Siyah 2.6.something (latest one)
I should also mention that I'm using the Samsung 2000mah extended battery. CPU has been oc'ed, uv'ed and set to 500Mhz-1600Mhz "On Demand"

You do realize that generally this will use more battery than staying constantly connected to wifi.
3G uses more battery than wifi.
If you think about it, the cell tower is pretty far away compared to your router.

Looks good buddy. But what would happen if you had the 500Mhz to 200 instead? Would you not have got a bit extra out of the battery?

Steve. Why would it eat more battery? I mean screen is off but having wifi on will keep your phone awake. A thing that is not really needed and would eat more battery.

Having wifi on will not keep your phone awake
Because if you have a constant connection to your router that is 5 foot away your using less battery than it constantly polling to the data tower which is prob a few miles away.
If your out and about turn wifi off as the constant searching will decrease battery.
There is a fair bit of info on the web about this, i'm afraid i haven't the time to find it out now, have a search tho.
there one example

nice one fella thanks for the link...i always thought it was the other way round. and yeah i know i always switch it off when i am out as like you say it will eat up battery by constantly scanning to find a connection. so best to use 3g when i am outdoors

exactly so maybe sometimes instead of having 3g best turn it to 2G or Edge to save up bit battery...

Best Battery Life Build for Sense

Well, i personally love sense. But i hate the battery life. If i tune down the CPU, it gets a little choppy with every ROM no matter what its at for sense. But i was wondering, what kernel or tweaks can i do to fix my battery life issue? I run screen brightness at 1/5.
Ive been around here for awhile and usualy just get "lower your cpu" or "change kernels" but no specific life amounts or which ones.. Aparently all the good ones wont work with sense =/

You gunna have to search the forums a little cause I'm on my phone, but if you know how to insert init.d scripts look up kernal tweaks, umm smurf script by its self also works well, I use cfq I/o, I have my CPU freq maxed out on more lionfish, running smart ass v2 peformance tweaks, that gives you amazing peformance when you need it, and dosent take away much battery, and saves battery like crazy, when screen is off, tomorrow ill go on my comp and send you script or link if you'd like
sent from my EVO EXPRESS 4g

Ok thanks. would love to have better battery life. And im still somewhat new to this. I only know the basics of wiping and flashing and using setcpu and installing kernels =/ so i barely know what alot of these things are like smartass v2 eventhough ive heard it.

Smartass is a governor option when tuning your CPU. It runs the frequency speed in between the two choices you choose 998/384 or whatever your preference may be.
I would suggest flashing the classic rom by tommytomatoe. It gave me the best battery life on a sense ROM. NRGZ sense 3.5 ROM also lasted me awhile. Nothin will compare to Aosp tho since sense is a battery hog. Good luck

Look for Calne's underworld kernel in the same section as your question. It's sbc and overall excellent kernel.

Trust me, make a step and you will love an extra juice. Again it's up to you. If you don't like it you can always flash another kernel. Just remember to wipe cache and dalvik cache.

Using Anker 1700 mah batteries (a small investment), the ROM in my signature and a STOCK kernel. Idk, I was a little apprehensive about stepping backward in Sense versions, but the phone seems to like what it was designed to run and does so fast, with no hiccups and smooth.

There's a lot of stuff to try for battery life. If you're looking for a miracle answer, you'll not find it. You need to try different kernels, read up on governors and what they do and so on. The link is to a script that has really sped up my EVO and I believe it has helped with battery life.
I was noticing the shots in this thread showing other's battery life but just remember, it's also what you use your phone for. High data games, surfing, Facebook, using GPS type apps will suck any battery dry. I use my phone a lot and am very happy to make it home in the evening to plug it in. Typically it can last 10 - 12 hours with about 5 - 6 hours of use. And I have tryed almost everything out there. Good luck and have a good time reading up on this stuff and trying different things. It's part of the fun of having a phone that allows you to tweak it. (Suck it, iPhone!)

you make very good points. for instance, i generally keep mobile data off because that is a killer. I also rush like crazy when i turn the screen on to get it off as quickly as possible. UV scripts do help

i get max 13 hours on the mikey rom for my evo 4g i guess its ok just has an overall horrible battery life.!

Maybe this is cheating for the purposes of this thread, BUT this guy ripped out all the Sense stuff he could and put in Go Launcher Ex, which would use less battery life.
http://forum.xda-developers.com/showthread.php?t=1550526
It would look much like an AOSP ROM, so I dunno if you'd like that or not, but it has the sense stuff behind the scenes (e.g. kernel).
I got good battery life with it, but i didn't benchmark it or anything.
