I've noticed significantly better battery life on sense roms (especially senseless gingersense roms) as compared to AOSP roms. On AOSP, my cellular standby tends to be over 40% of my battery life, while on sense roms its under 3%. What would cause that?
I've tried evodeck 1.3, cyanogen 7.1, and cyanogen 7.2 rc1, with savaged zen, and tiamat kernels.
Also on AOSP roms, if I undervolt 50mv or more, my phone locks, but I can run the lionfish aggressive kernel completely smoothly.
As to sense roms, I've had the best luck on SOS N with universal aggressive lionfish 1.8
This disappoints me because I like the AOSP messenger, and AOSP dialer/contacts.
Is there a way to get the AOSP dialer, and AOSP messenger on a sense rom? I tried backing them up with titanium backup, and then restoring, but I have was having issues with the contact list, and when I opened the messenger from contacts (even with the HTC contact list), it wouldn't carry the number over, and I'd have to search for the person to text.
Try tommytomatoe's classic sense rom. I remembered one of his senseless roms had aosp dialer and contacts.

After some looking, I found what you're refering to
however, there have been some important updates done since that build was released... these 2 things drew my attention
Completely rebase of apks
Completely re-optimized pngs
Wouldn't that cause some performance issues not having that done?
Would it be reasonable to take the newest sense build (supermagic), install go launcher on it, and remove rosie?
Dont know if this helps, but I have been running cyanogen 7.2 rc1 w/ tiamat for months now.
I like to run Smartassv2, and let SetCPU control my overclocking based on situations (charging, etc).
I dont see major dives in battery life, and have been very happy with the results.
My cpu usage isn't the problem. Its the cellular standby. I don't understand why its consistantly so rediculously high on AOSP roms for me.
TT's classic is equipped to be either Sense, non-Sense or a hybrid of the two.
It includes Launcher2, Stock GB launcher, as well as both Sense and AOSP dialer and contacts.
You could easily use it with GoLauncher and have even more options then.
As for the cell standby, are you speaking of the percentage shown in battery stats? Remember those are percentages and don't indicate that something is using "more" but that it is using a greater portion.
I have noticed that cell standby is usually at the top followed by display, then a few other things. What I can say is that Sense has many more operations and is probably just taking more battery than the cell standby, though your actual usage is probably the same. Can you say for sure that your battery life is worse on AOSP? I know I cant beat CM 7.2 with stock kernel and all stock CPU settings. Believe me I've tried it all.
As of right now, I'm at 55% display, 20% cell standby, 6% facebook, 5% wifi, 4% google services, 3% android system, 3% browser, 2% phone idle, and 2% android OS. I'm 150mv undervolted, using 128-384mhz ondemand screen off, and 128-576mhz screen on with smartass v2.
Most of the time, I'm over 75% display usage and under 3% cellular standby, but I'm in an area with near zero signal right now. When I had cyanogen 7.2 RC1 with the tiamat kernel (which is an undervolted cyanogen kernel), I was about 40% display, and 40-45% (sometimes even past 50% for cellular standby).
The display, even at 5% brightness, is the biggest draw, by far on sense, and comes in 2nd on AOSP.
That would conflict with your idea that it's sense that is burning my battery up (especially since I'm using sense-removed roms that are sense based)
I'm using swagged out stock 2.0.9 N, which comes by default with the go launcher, instead of sense, but uses sense kernels.

I'm barely using any power on my CPU, due to the heavy undervolt and underclock. This issue is purely cellular connection based, which is significantly worse on AOSP for me.
I didn't say Sense was using more battery, I said it has more processes.
The question is does your battery actually last longer on Sense vs AOSP?
Your battery gets used, and each process uses a percentage. When there are less processes the percentages on each are higher, though they still only equal to 100% of your battery.
Also, the different roms use different methods of collecting those stats and display the differently. Just how AOSP displays signal based on the actual dbm and sense displays call quality.

I do notice significantly slower battery drain with sense. I'm not just staring at measurements.
That MAY have to do with the fact that I'm using setcpu on sense, while setcpu doesn't work properly with most AOSP kernels, due to HAVS.
Honestly, I have never had such a jitter free experience either. Every rom I've tried felt slow to me except SOS N... Maybe they are working some kind of wizardry

HAVS has nothing to do with the cpu speeds so its unlikely that its not compatible (i know because i used it all the time on both aosp and sense) all HAVS does is let you change the voltages of your cpu. but if it isn't working well i would recommend using the system tuner app (free version in market) and over/under clocking in that. its much better from what i have observed. when you do it click boot settings right next the the sliding cpu speed bar and make it re apply cpu setting via init.d script and reboot. also try using the mason g .15 test build kernel. im currently using it in miui and i haven't experience battery like this since tiamat 3.3.7 (the god of tiamat kernels) and the performance is amazing!
have you been calibrating the battery? and i dont mean just wiping battery stats i mean charging it fully (at night/evening) then letting it go over night and then you really will stretch out the battery life. I have seen 30 plus hours on decks 1.3 with tiamat kernel.
if battery calibration was an issue, wouldn't it still be an issue when I flop back to a senseless sense rom?
I always have better battery life on Sense ROMs too, even with Rosie active still. I haven't tried SOS N yet because Go SMS doesn't behave well with the poor reception at my house.
Maybe the improved performance has to do with go launcher, zipalign, odex, and the pngout improvements
Maybe its the SIO scheduler... who freaking knows...
SOS N doesn't natively use go SMS... it uses HTC messenger, and HTC dialer, with go launcher

For real? Save up some loot and get an extra battery and an outlet charger and you'll only have to worry about charging both batteries at night -- one in the plugged in phone and one in the outlet charger. Crank it up to 1ghz, Install JuiceDefender, You will get 3-4 hours of on screen time (autobrightness) out of each battery, so even if you are putting the phone through heavy use you will still be good throughout the day.
My daily is SOS X/ODEX , Underworld .5, 128/1152 smartassv2, no undervolt, no profiles. I use juicedefender ultimate. With heavy use i have to change batteries throughout the day, but with moderate use, the battery lasts 18ish hours. I wish I had screenshots, but i don't, the phone is fully charged right now so taking one now won't do much.
http://www.amazon.com/Battery-Travel-Charger-Incredible-Verizon/dp/B003ZBWLW6/ref=pd_cp_cps_1
Juice defender annoyed the crap out of me, and didn't do what I wanted, since I often go a long period of time with ALL data completely off. I'd rather have complete manual control.
Overclock is pointless to me, since even at 576mhz, my evo doesn't feel slow to me. Higher clocks just aren't helping. I have everything else optimized enough that any CPU delay becomes irrelevant. I had it at 768mhz, and lowered it to 576mhz, because I couldn't feel a difference.
I had issues when I used to use governors that were not smartassV2 but once I got that, there was no purpose to me having the higher on screen clock.
Thats what happens when you have SOS N with components stripped out that you don't use
Autobrightness actually screws your battery up by putting too much load on your CPU with polling
I still get a full day of charge on SOS N, I just don't on AOSP. I made this post trying to figure out why I'm having issues with AOSP.
I'm trying smartass from 128 to 768 with ideal freq set to 384... Works much better!
You said you don't use set CPU with aosp cuz of the havs kernels.
1) don't worry about the havs, not an issue
2) you don't need set CPU with aosp roms, control is built into the settings
sent from 2yr old Evo on ICS
I use setcpu for screen off profiles.
Can't do that with stock.
I recently tried smartass, setting ideal, awake, and sleep freq to 128 (works surprisingly well), and screenoff, ondemand 128-285
Seems to work well.

I know this is beating a dead horse to a pulp, but I'm going to ask any way. I have never been a typical user, and I burn my phone to the ground fast. My usage fluctuates so much testing is almost impossible.

I have the same setup that you do and it seems that I am blowing through my battery even faster with the lower voltage, which makes no sense. I also have noticed significantly worse battery life with DJ05. Not sure if you have noticed these things as well and was the reason for the post.
Im not sure if super clean 0.9 is based off of dj05 as I use my own fragmented rom with prices of everyone elses ROMS. But the best battery life I get is out of dj05 for sure. Running a random kernel that I think adrynalyne or jt posted in irc and I usually get a full day with moderate to heavy web browsing and 3-4 hours of music. But I also have outstanding 3g in both of the places where I live so that doesn't deplete my battery like most people

With stupidfast 1.54 and superdark dj05 I feel like battery life has improved. I can go through a whole day, minimal use, and still have 82% battery life at the end of the day or hover around 40-50% with regular use.
its 9:20pm right now and I am still at 76%. With some browsing, music, phone calls.

I have seen the same with lv kernels both here and on my N1. possibly needing more pull for higher resource usage, but I'm lacking on the technical knowledge to make sense of that, and have had too much egg nog as of now.

I somehow seem to get better life from a stock with BS apps removed, but like I said, haven't tested properly. I usually hate battery life threads but have been aggravated by 9-10 hours before death as of late. Probably just excessive usage, but I'm banking on the community to share exp. with their phones.

ROFL. If I could ever put my phone down i might see better life. I like the stupidfast, but saw some minor performance delays that led me back to voodoo. Not much of an improvement on my life tho.
I have been frustrated with battery life on the sf from day one. I called VZ the other day to have the lady tell me it's normal to charge it 3 times a day due to widgets, I then proceeded to waste my breath by telling her I don't run widgets.. Her response was well they will still drain your battery.
I don't want to un root my phone just to take it in to a store and get the battery replaced and apparently calling them won't get me any where either

I use blue tooth + 3g for an hour drive to work and since the voodoo 5 kernels with the ul settings I have been at 85+% each day from the normal 75+%. So my battery life has improved greatly! Keep up the awesome work devs!

I get pretty decent battery life out of the DJ05 OTB Voodoo sv combo (around 7 hours with periods of heavy usage). I also use juicedefender but I've heard it cant control the CDMA radio properly (ie disable data and etc) but it appears to lengthen my battery life (could just be a placebo effect however)
I had the same problem....crappy battery life with DJ05 and I tried everything from wiping to endless kernel/rom combos. In the end I found out standby was killing me. Like sometimes an hour would pass without me touching my phone and it would drop 5%. Someone suggested dialing *22899 ( I think that was it) and it was instantly fixed. Now idle I drop maybe a percent every 3 hours.
What I have found is the governor does a great job of managing battery use of the CPU in conservative mode. My best combo is jt 1129 novoodoo kernel paired with black hole 2.1+ (I noticed no significant difference between 2.2 and 2.4 for battery life). My usage is fairly high, 3-8 hours of display on each day, running light apps (hardly any music, never games, synched email). Some of my numbers are posted.
Counter to intuition, I can't seem to get aggressive undervolt kernels to give me an improvement. I think it is because the minimum processor has to be kept a little higher to sustain the underlying, so on average more offline drain. This makes no sense though, because when I look at it in os monitor, the governor seems to be doing fine.
Speculating here is pretty dicey, because I have a hard time doing a lot of testing of something that doesn't seem to work. I use my phone a lot, and it is hard to justify having 40% less life span when I know of better combos.
In summary:
* I have NOTHING to say about voodoo kernels.
* negligible difference from leaving wifi and GPS and live wallpaper on.
* negligible difference between dj05 roms.
* running a custom rom gives a noticeable improvement betrays simply running ADW on to of touch wiz
* stock kernel is pretty darned good for battery life, competitive with best kernels.
* the cpu does great self management stock and mostly runs at 100 mhz for my use
* certain under volt kernels appear to under perform during non intensive tasks, but it is hard to be certain.
* bluetooth matters, only turn it on when driving or planning to talk; it does eat battery.
* leave brightness at auto or lower, pick a dark theme wherever possible. Display is the number one eater of battery. White sucks your life.
* there isn't a lot you can do to optimize battery life. Retraining the battery either works or it doesn't, but it isn't really necessary for most system or kernel changes and should be done infrequently.
* there are a few ways to eat battery fast.
* use a theme that shows battery in 1% increments, great for sanity!
* rule of thumb display on uses 4.5 times the power of display off for light apps. -- So theoretical max life on this phone is around 8.5 hours with display on, 42 hours with display off. (typical is about 4.5 hours of display on before I charge it) and yeah I should check my math... I have never had a practical test anything close to 8 hours. I would expect about 6.5 if I never locked it and kept it running in a dark app, with little data and sound use. I think a review I read got about 7.5 hours of playing avatar on loop (probably tmo galaxy s)- a result I found mystifying at the time. My personal best is about 5.5 display on.
Swyped w/ XDA App. When in doubt, jingle.
That was very informative.
I'm on Blackhole 2.4 and I tried one of the Stupidfast undervolted kernels (v1.5.4) for a week and although the battery useage improved a bit, it was somehow affecting my phones wireless reception, wifi and mobile signal. My phone usually flies thru webpages at home when it gets wifi yet it was crawling when I was on that kernel. My phone would randomly freeze as well. I just switched back to JT's 12/12 DJ05 kernel and eventhough battery useage is less desireable, I got my wireless reception back. I also just switched to a dark wallpaper, used to have an ocean / blue sky image as wallpaper. I think those beautiful/fancy weather/clock widgets affect battery useage on how often it updates itself. I switched out of beautiful widgets to gTabSimiClock widget, see if that makes a difference. I like its more simpler look.
Right now I'm using RoyalGinger 3.0 on my HTC Panache.
I know that it's based on CM7, but if I switch to the actual CM7 Nightly or Faux's ROM which I'm also considering, will I get noticeable improvements in battery if I maintain the exact same usage patterns?
Hmm. That's difficult to answer. RG has really good battery life. Faux's ROMs focus more on raw speed than battery life, but still give decent battery life. CM7 doesn't have as good of battery life as RG, but usually lasts all day with all but heavy usage. At least, that's what I've found. Your mileage may vary. Your choice of kernel is important, so keep that in mind.
Sent from my HTC Glacier using XDA App
With moderate usage, I average roughly 11-13 hours using Royal Ginger and the kernel it comes with. Couldn't really find any benchmarks so not sure whether this is typical or not
This is with brightness set at the absolute lowest (Display On roughly 3 hours), Wifi never on, GPS never on.
OC'd at 1.1/245 smartass. Trying out On Demand to see if there is any difference
Well I know its not RG or CM7 but I run Virtuous Unity 2.35 and I am averaging 16-20 hours of battery with a average of 2.5-4.5 hours of display. It all depends on what you do with the phone.
There are many ways to help improve battery life. For instance Battery Calibration on the market. Follow those instructions and you wont go wrong. Another being Juice Defender (paid or free). A friend of mine is using an AOSP rom for his Evo and is averaging 30+ hours with Juice Defender.
Had no idea about that Battery Calibration app. When I flashed RG (and now MIUI), all I did was let the battery run down to 2% through regular usage and do a full charge until 100%
Flashed MIUI the other day, which I've heard nothing but good things about, including battery life, and am following the instructions of Battery Calibration now.
Not the biggest fan of Juice Defender. Had used the free version for a few days, and I found that sometimes it wouldn't re-initiate my data after the screen turned back on (which seems to be one of the more prominent features to save battery)

I agree with the Juiced Defender, that's the reason I don't use it.
For instance, when we are car pooling to school he has problems keeping pandora playing because Juiced kept turning data off. So he disables it when we are driving.
You don't have to use Juice Defender, of course, but the reason it re-initiates data when you turn the screen back on is that it turns the data off when the screen turns off. Turning the data off is what saves battery.
Have a EVO now with Sprint Lovers ROM on it. kinda cool I suppose. However here is my big thing. I use my phone mostly for email / some texting and a boat load of talking. SOmetimes I will be on a conference bridge for 2+ hours straight. problem is I seriously have to have a charger handy all the time. Cuz I can pull off my phone from the charger after charging all night and loose 1-4% battery life right away. Not sure what thats all about.
I just last night did a battery calibration and installed setcpu (paid version). and this seems to have helped some. but not where I'd really like to see it.
I know with using on a average-high day 500+ minutes during that day. it's not going to last me all day. thats fine. but having to plug it in before lunch time to recharge it, seems a little to much for me.
I am open to any and all suggestions on what/how to fix this. new ROM, software hacks etc... or both.
Software I run:
Flex dialer (paid ver)
built in email client (checks 2 different account every 15-30 minutes, which i know is a battery drain)
text (average light use)
CSIPSimple (sometimes)
web browser ( once in a while)
Thanks for the help!
Try an aosp rom like CM7 or Miui they get better battery life than a sense rom.
Best battery life I've ever gotten was with the Deck rom 1.2.1 and the savage zen BFS SBC kernel version 2.2.1. If you couple that with an extended battery you could go for days without charging.
With a year old stock battery and that setup I had pulled 20-36 hours (I know its a broad range, but 20 hours was the low) depending on usage.

When your battery reaches 100%, your phone stops charging and lets the battery drop down to 90% before it will kick in again.
any AOSP such as CM, Decks, omfgb, miui.us, ect. coupled with tiamat or savagezen SBC kernel you will be free of charging worries & smiling.

So I downgraded to .32-kernel, because I realized it works way more better than .35(better signals and batterylife). But still my battery drains like 10% in about 2 hours, without doing anything. This came up with eliterom 9.7, but cm7.2 also drains battery pretty lot. Miui is the only one I haven't tested, and I'm soon about to. But I'm asking, which .32-rom would have best batterylife and with wich rom and what governor- and i/o-schedule-settings? thanks!
Don't worry too much, just enjoy!
Hey!
I think the ROM with the best battery life would be either Oxygen or MIUI, but probably oxygen. You should try it, it's very stable, clean gingerbread, and it looks gorgeous with the ICS theme.
On the other hand, I'm getting a pretty good battery life with 9.7 Elite (from 8, 9h until 22, 23h, with moderate usage (a few sms's, moderate wifi usage, music) I still have around 30, 40% left). Using wifi, gps, 3G, etc. only when necessary might help, as well as using the app killer every once in a while (so you don't have a bunch of stuff running in the background and draining your battery), using automatic brightness...oh and about governor and scheduler I personally use smartassV2 and deadline (respectively), and my battery lifetime is the described above.
Also, try not to worry too much about battery drains, lower benchmark scores...I'm saying it because I did that when I bought the device...as long as it lasts the whole day and does what you want it to do, just enjoy your phone .
the combination of CM7&Franco kernel also worked for me, i could use the phone upto 2 days.

Oxygen is better than others BUT I'm still getting 2 days with aurora ICS but I uninstalled facebook. Facebook drains so fast (literally fast, very fast). I'm using 800-300 mhz with ondemand and noop. I'm using apex. auto brightness. messaging so much but not talking much. sometimes surf on app market, sometimes play some games or every morning and night listen radio for 1 hour and battery goes for 36 hours. It's about your way to use the phone. but if I were u I would use oxygen or aurora ICS. both of them are good.

I get a drain of 4-5% per hour on CM10 which isn't normal. According to BBS I don't see any excessive wakelocks, also battery stats in settings shows phone sleeping.
I tried a lot of different things to see if the drain reduces. Finally when i changed 3G to 2G the drain reduced.
I know 3G consumes more battery than 2G, but this drain was excessive and nothing like I saw on Stock or CM9 ROM's.
I'm using PA 1.98 and Siyah 4.0.1. I feel this is a very good combination in terms of battery life and performance.
On a full charge, I easily get around 20hrs on medium-heavy usage. I used Lux AB to control brightness and VC just for reference to check on deepsleep and cpu states. I also used battery widget reborn beta for its cool stats and auto flight mode control. Disabled all haptic feedback and vibration alerts cos I could just use a low-volume profile.

I have very good battery life with version 2.7.0 and CM10, but USB Mass storage isn't working. Also you can try newest Siyah.

I get a drain of 4-5% per hour on CM10 which isn't normal. According to BBS I don't see any excessive wakelocks, also battery stats in settings shows phone sleeping.
I tried a lot of different things to see if the drain reduces. Finally when i changed 3G to 2G the drain reduced.
I know 3G consumes more battery than 2G, but this drain was excessive and nothing like I saw on Stock or CM9 ROM's.

Yes, I experience the same. 3G draines the battery and much more than on any other ROM I ever used.
My battery is no better or worse that on other roms, i loose about 15% of battery an hour with half an hour use or so. Any screenshots anyone? Or tips, did anything improve your battery??
i using CM10 ,the battery consumption still bad compared to stock rom ICS..so,no different to me,LOL

I get that in every ROM, even stock. I get half decent battery life now, deleted battery stats this morning so gona see how it goes tomorrow. It almost got me through the day though. I'm using extweaks to under volt my phone

A drain of 8-10% per hour if you actively use is fine. But while sleeping my usual drain on stock /CM9 is about 1-2% per hour.
I think due to all the hacks that are required currently to get CM10 working with ICS closed binaries we have this battery issue.IF it was
an app BBS would have shown, if my phone had deep sleep issues, cpu spy should have shown but I don't get anything in either of these.
CM10 on Galaxy S2
I'm running the latest CM10 nightly build (20120906) for my Galaxy S2.
The ROM works blazingly fast and I haven't had any bugs as of yet :victory:
The battery life is quite poor however, I get around 11 hours from full battery to nearly dead with moderate-light usage.
Today I used Google Navigate with GPS and 3G for around 15 minutes and it chewed through around 15% in just 15 minutes :crying:
I really hope they fix the battery life as its the only thing holding this ROM back.
This was my rom drain on standby with cm10 pretty good in my opinion

That's pretty awesome. Care to share the build and if you did something else (other kernel, settings, anything)?
my phone has battery problem with CM10 too
battery dead 2x faster than CM9 Rom
specially when use Wifi or GPS
i never had my phone for more than 20 hour
I am using CM10 nightly 20121017. I have switched to CM10 nightly builds since two weeks. Before I was on stock 4.0.3 Greek Vodafone. Also I have tried a lot of custom ROMs.
In conclusion: with 3G on, WiFi keep alive, gmail, push exchange mail and all other notifications off (eg Facebook), all touch vibrations off, from 8am that I unplug the phone, it lasts max until 5pm. And this is Almost the same with all roms. :thumbdown:
This is a smartphone and in order to operate as a smartphone of consumes a lot of energy! I can get a Nokia 6310 to have just a phone that lasts for a week...
My opinion is that someone must produce better batteries!

I hardly get a day of battery life. The most efficient battery saving technique which I realised was to put your phone into airplane mode when not in any use. I put my phone to airplane mode while I am asleep or I am attending classes. Amazing battery saving technique.
Other thing we can do is to use a cm10 version of rom with the memory leak issue fixed. If its not, you might even need to charge your phone even twice a day.
Disable 3G(use 2g only mode) when not using the web. 3g sucks a hell lot of battery.

Easy when you know what you're doing
