Official Froyo battery life thread

Wanted to start this so we can get a better idea of what kind of battery life we will be seeing with 2.2! Please post your opinions so far and if you are rooted/stock and using stock kernel or the .34 kernel cyan posted. Hopefully we won't see much of a decrease do to JIT or any other new features

Probably won't be that great the first couple of days...testing out Flash and everything...(watching Hulu right now).

i was on CM5.0.7t2, and as we all know, CM is known for draining more battery than the stock rom/enoms but so far im seeing same usage as CM which is ok but not great. next few days will be testing for all of us. hopefully we will have similiar usages not like before where some people are getting 40 hours and some 10 lol

I dont if theres an improvement but I updated on a full battery. After I had 97% then killed the battery in like 5hours while at the Engadget Show lol

is anyone running setcpu with FroYo? im already gettin horribad battery life...probably due to Hulu

I may have done something wrong, but I'm on a rooted phone with kernel 2.6.32.9-27220-g328f560 and my phone went from 80% to 10% in about 4 hours just sitting in my pocket. The most I did was check some emails and some basic SMS.
Will monitor closer tomorrow by my battery usage shows something like 19% email. I wonder if my outlook push is doing something constantly that is hurting it.
Edit: it's also charging REALLY slowly. I have it connected to a USB port and its taken ~ 30 minutes to go from 14-16%.

So far, mine is looking pretty good. Early days yet though.

Its better with froyo.
Had to charge every evening with CM 5.0.6 and pershoots kernel, now i get almost a half day more (with more "playing around").
I use setcpu (245/499 at sleep).

My battery is showing 99% after 3 hours switched on and with light usage. If true, that is amazing! More likely something is not quite right. I am using the .34 UV kernel from persionsown he posted on twitter....

The Jones.. gotta try that Kernel..

If I believed that it were a true reflection of battery use and not a mis-report of some sort, I would be shouting about it a lot louder!!

i streamed about 1.5 hours of video via qik (uploading not DLing). Still have 60% battery left. I say that's an improvement. Rooted modaco froyo

I'm seeing what I think is significantly worse battery life since I installed Froyo. It's hard to say, though, because I've been playing around in ways that are different from my normal usage pattern (checking the market frequently for updated apps, for example). I was on stock 2.1update1 and now am on stock Froyo.

Battery life is definitely better than Cyano/Modaco/Enomther but it is also worse than stock ERE27. Can definitely make it through a day still though on moderate/slightly heavy use with Froyo something I can't do with Cyan/Modaco/Enom...and this is way faster and more fun than any rom i've had previously so no complaints from me.

Well I was running cyan 5.0.7 and it lasted me longer than this I have now, which is Paul's Froyo.. but since my wi-fi finally stays on I wont revert.
Question: can I still install older custom kernels on froyo???. Want to try...

My battery died sometime last night, and I had gone to bed with it 70% charged. Prior to Froyo, I was on CM 5.0.6 and usually using intersectraven's 925mv kernels, and I would lose about 1.2% per hour while idling.
I'm not blaming Froyo yet, since it could have been an app screwing around. However, the battery usage page didn't show anything out of the ordinary. It will take some more testing before I ditch Froyo until an update is released.
BTW, battery usage while actually using the phone seems to be about the same.

my battery life was phenomenal today. i can't give percentage, because i haven't put on a battery widget (or many widgets at all, tbh), but stock froyo treated me well. was above 80% (guessing by icon) when i left work after 8 hours, some hulu, some wifi, some texting, some phone calls. not exactly heavy usage, but not just idle either.

Great and extremely simple app. I've been using it for months. (And it doesn't drain battery either.)

ROM & Kernel with the best battery life?

Hi, so far the only rom I have used is CM6, and the battery life is just absolutely terrible. Maybe its just my nexus, maybe not, point is I want a new ROM.
A ROM that you guys have tried and decided to stick to.
Battery life is VERY important to me.

Try IntersectRaven's CFS kernel, best I have found for CM
For ROM try Enomther, battery life pretty good on that one

I had been using CM 6 for a while and just recently switched over to Enomether's latest TheOfficial ROM. The battery life is now DRAMATICALLY better. Just looking over the Juice Plotter graphs shows that the standby time overnight is almost flat. Say 3-4% drop every 3 hours or so. With CM6, the battery level is on a constant and steeper decline, even when not in use. I didn't take any records, but my N1 on CM6 would be down to ~45-50% overnight if I forget to plug in the charger (from full). I heard that SetCpu will help, but I don't think it worked out for me.
Enomether has its own CPU Governor and while it doesn't offer as many features as SetCPU - the ROM's default settings work well right out of the box - no tweaking is needed really for the CPU governor.

I too was having really poor battery life with CM6, losing about 50% within 8 hours after charge, without even using the phone much! I'm trying out other roms right now just for fun. I'm using Evil's Nxsense but with the kernal posted by Autinhyeu (post # 8541 in that thread). So far seems to be holding battery extremely well. About 5 hours since charge and about 90% battery.

LeoFroYo Rom is pretty good with battery

try the leofroyo rom latest beta. i get great battery in standby with the stock kernal that it comes with. 2.5 hrs per 1% battery. typically in a day making calls and using the internet, i lose about 30%-25% battery. not too bad.

cm sucks when it comes to battery life in my experience. i tried the 6.0 version when it came out (first stable release) and battery life was horrible.
5 hours since charge? only standby or some usage?

That was mostly standby with setcpu profile setting cpu to minimum when the screen was off. But even with those same settings on CM6 my battery would be about 70% after the same amount of time.
I just reflashed cm6 but with that other kernal so I'll see how well it works today.

MIUI has the best battery life of any ROM I've used on my N1.. idle drain of about .5% / hour when using pershoot's kernels from droidbasement.

I'm using shadow rom2.1 stripped down and I get about 16 to 18 hours usage.

I'm using CM6 and my battery life is great. I got rid of my Seidio extended battery to get an Otterbox case and the stock battery on CM6 is awesome.
My phone has been off the charger since before 1pm and now at midnight its on 46% and thats with heavy use of Angry Birds, text, emails and web browsing !

My battery life is also acceptable on cm6. Not amazing but acceptable. Then again I put mine in airplane mode overnight and get about a 4% drain, which I kind assume might be something to do with my Widgets.

Okay, so I decided to try one of these two ROMs:
Enomther
LeoFroYo
not sure which one yet, and not sure what kernel to use with the ROM I choose.
I hate switching ROMs cuz of the wiping and restoring and all that crap.

Appropriate steps to a better battery life?

Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?

turn off gps when not need
data when not needed

Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps

also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running

@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks

Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.

I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.

just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery

My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Sorry it took me so long to reply.
Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.

i owe setcpu and screen off seting for my battery life

I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.

I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!

Looking for a great Sense 3.0 GB rom with good battery life

hello everyone. I have been using Cyanogenmod 7.1 for a little while now. I am getting tired of it for right now. I am wanting to try something with sense 3.0 and GB rom. Which one's are great and fully working on the Evo? Also do any of them have better battery life?
P.S. I am currently trying out Synergy rom. My friend has the LG phones on Verizon and man they get awesome battery life. 12 hours off the charger and his phone is only down to 73%. He has been making a lot of calls but man my Evo was off the charger for 16 hours and was down to 15% and I barely even used the phone. I hope the Evo 3D has much better battery life, otherwise I may buy an 3500MAH battery for my evo.

Alliance Rom is pretty
Evo 4g

MikG-c2.15 is working very well - no issues at all. Battery easily lasts a day with fairly heavy use. This is probably the best ROM I have ever had on the Evo. (and I have tried MANY.)
RECOMMENDED.

I love Synergy and MikG but I can't use them as an everyday rom because of the battery life. With Synergy I watched my battery drop to 70% in like three hours after I had my phone off the charger for a few hours yesterday morning. And I had barely touched the phone! That is completely unacceptable to me, sorry. I need my SBC and HAVS. I wanted to go back to MikFroyo but I have an issue with the display usage (stays at like 90% even with the screen off and not touching the phone) that drains the battery in like 10 hours.
Tried to go back to my Salvage-Mod nandroid but it somehow got corrupt. I almost went back to Myn's twopointtwo but I didn't want something so outdated (still a great rom though). So here I am now using CM7...not the biggest fan in the world but it works and it's giving me great battery life with Tiamat kernel 4.0.5. A little over 20 hours with medium usage.
I don't understand what happened with MikFroyo. I never had the display usage issue before. Then it just came out of no where and stayed like that. I tried going back to 4.5 (which I know for a fact it didn't do that on) and it still did it. Tried switching kernels, nothing. I used to get 25-30 hours with a charge on 4.62, and Salvage-Mod gave me the same battery life. So I'm just hoping that new kernels with SBC and HAVS will let me be able to keep Synergy or MikG as a daily.

Keep me updated. I have been using Syngergy today and battery life is ok. I would go back to CM7 but having all of the random reboots when 4G is turned on kinda got old.

I need my SBC and HAVS,. also, but you DO know you cannot judge battery life right after flashing the ROM, right? You DO know you have to let it settle in for a day or 2, right?

this is with 28% remaining after heavy use
this is with 12% remaining after heavy use (ignore the 28% in the header...)

DesireZ ICS Battery life, is yours worse?

Hi all,
Just wondering if your all seeing reduced battery life with the ICS builds for the DesireZ?
I was using Miui (2.x) and now trying out Ice Cream JIBWich,and Im discovering the battery life is most certainly less. I've also tried CM9 Alpha and Andromedus r13, all roughly the same.
Battery Widget reports on average 40(ish)mA in sleep, I havent compared it to Miui but just wondering I've done something wrong here..
Install procedure this time was a factory wipe.
Comments?
Angelo

I don't know if my battery life is worse on ICS than on CM or stock 2.3. Because I don't have any logs of battery life. Maybe I will do some tests in next week, just for curious.
So... I'm getting 30mA - 34mA drain on idle on Andromadus v13 with default kernel. It is lower than yours. I'm using latest radio now (.19).

After implementing new features and fixing bugs, there is a stage of development called optimization. That is when you will see all the battery life milked out of a rom.
And none of the ICS roms are even close to that stage, so battery will probably not be indicative of the final product.

I don't have any hard numbers, but based on my moderate usage, (8am to 11pm) I go from 100% to about 40%. Fairly good IMO when compared to sense roms (that i'm used to) but not as good when compared to AOSP GB or MIUI roms..

Hmm I found my battery doing suprisingly well compared to aosp gb, now that I'm using ics its lasting longer than ever.
It probably has to do with better app/process management.
That's my experience..

Well, this might sound strange to say but i'm actually getting the best battery life i've ever had out of ICS so far with Andromadus v13/Jibwich 1.3 on my phone. I seem to manage to get really long charges of at least 48 hours. Maybe i'm not using my phone as much as i was with GB? I'm not quite sure if that's the case or not, but i'm consistently getting longer lasting charges than ever before with GB.
Thing is though that ICS ROMs DO seem to drain the battery more while the phone is actively being used (in comparison to AOSP GB ROMs), this seems to be the case for me, as well as some other people that i've seen.
There were a few strange versions of Andromadus and Jibwich though which seemed to cause severe battery drain for me. Fortunately, that hasn't been the case with any of the latest versions.
All of that said, i still don't think anything compares to the battery life on G2 Slim (Gingerbread AOSP ROM), that ROM has ridiculously good battery life. With that one, i'd use my phone a fair bit (couple hours of tethering, gaming, lots of texting and calls) and it would still last for at least 44 hours or so.
In the end though, there are still some GB ROMs that have much worse battery life than ICS for me. For example, all CM7 variants that i've tried has always had this frustrating radio related battery drain, then some Sense ROMs seem to drain the battery a bit more than AOSP ROMs too. In response to the OP, i never really got amazing battery life with MIUI, so ICS has been a much better experience so far in that regard.
What i do know for sure though is that battery life with ICS is MUCH better than the stock gingerbread OTA update that our phones got.

thanks all,
I've done some checking and according to battery monitor, my JIBWIch rom seams to be fluctuating .. from 36mA to 97mA in standby which to be indicates something's running.. not sure what... Anyone recommend a decent process monitor, there's soo many of them

Agreed..
I'll see how it goes but I might have to go back to Miui (GB) as I use the phone for work..

Here was my (personal) record breaking charge on Andromadus v13 https://www.dropbox.com/gallery/12263406/1/screenies?h=c9ef42
You can see part of my configuration there (radio and CPU speeds).
On top of what's already there, i use supercharger RC6.9 with option 6 and nitro-lag-nullifier.
here are my usage patterns for good battery life:
-I generally stick to 2g networks as i don't do much web browsing while i'm out but when i do, i just switch to 3g.
-I also don't regularly use any task killers but if i detect any choppyness i kill app using Advanced Task Killer.
-I don't use auto-brightness and instead i just use the notification power widget.
-I do lots and lots of texting, some calls here and there, i often use wifi hotspot and i play 2d games a little bit at times, so i'm generally a light-moderate user.
-I also "debloat" as much as possible by getting rid of any system apps that i don't use.
On a random note, right now, i'm using Jibwich 1.3 and it is so great, battery life seems the same as andromadus v13 but this ROM is actually much more smooth and fluid on the home screen.
I hope this helps a bit, give me a thanks if you found this useful ;D

hey thanks for this, yeah very nice!
Just occured to me, im currently in Madrid (Roaming), and the phone's on 2g at the moment, I WONDER.. just wonder, if its constantly hunting for 3G signal.. now that would account for the random power demands...
Meanwhilst I found this app http://androidadvices.com/save-battery-android-phone-enabling-2g-network/
Apart from adding a 2g/3g toggle it also makes the phone go to 2g when sleeping.. I mean when its sleeping we dont need 3g access....
Anyone else tried it? or can recommend a different better/app?

Go to settings --> wireless and networks --> mobile networks
Now see if you have "use only 2g networks" checked. If you do, that'd be why you're always connecting to 2g networks.
As a battery saving tip, it's best to always check that option when you don't need mobile data (like when you're at home and wifi is available).
In addition to that, if that option is NOT checked, then your phone will connect to 3g networks where applicable, you have to check if your carrier actually uses 3g networks on your plan.
Also that app seems fine, but i wouldn't use the "use 2g when sleep" option because that could cause problems with reception between waking and sleeping because it'll be erratically switching between basebands all the time.

Hi all,
Just wondering if your all seeing reduced battery life with the ICS builds for the DesireZ?
I was using Miui (2.x) and now trying out Ice Cream JIBWich,and Im discovering the battery life is most certainly less. I've also tried CM9 Alpha and Andromedus r13, all roughly the same.
Battery Widget reports on average 40(ish)mA in sleep, I havent compared it to Miui but just wondering I've done something wrong here..
Install procedure this time was a factory wipe.
Comments?

It looks to me that yes. Tried 3 ICS inluding JIBWich and CM9 based and battery life was reduced to me about 1/3 maybe 1/4. looks like that. Hope some improovment will come in near future.

I'm running Andromadus v13 and it seems to be only a bit worse than the latest CM7 nightly. However, this is only my subjective opinion, it could be that I'm using my phone more with ICS
I also have the .19 radio and the tweaks associated with v13.

Well from what i've seen, ICS has very steep and sudden drops in the battery stats graph when the phone is being used. This is in contrast to many gingberbread ROMs which just have a sloping negative curve on the battery stats graph. This seems to indicate that ICS uses more battery when the phone is being actively used.
I'll post pics after this current charge is over to show a comparison of ICS battery life with Andro v13 and GB battery with Virtuous G-lite 2.0.1.

I don't see any difference between GB and the ICS battery usage, maybe because i allways configure it from begining and don't restore apps via titanium backup or any other app...
Also battery needs to calibrate under new ROM and after few charges you will see it working little bit longer and longer...
ps. Do you have disabled Google Talk on ICS fresh install? He is always on after installing and eats a lot of battery.

I also configure all new rom's from begining and on Affinity 2 - my battery in averange usage die after ~16h but on ISC os about ~13h, I don't know why.
My battery after full charge get 4.212 V , tried clear battery stats bin no effect

My avg runtime on one charge on CM7 w/o oc, with ilwt or pershoot kernel is 60hours (yes! 3 "work days") or atleast 2 days with 50-70 min calls and 25-35 SMS
Turning data and/or wifi when needed makes phone battery least looooonger...
Now testing Andromadus Audacity b1, charged 7.5h ago (4207mV), i will post when empty (or near ~3600-3650)

Also remember that we don't have the proper kernel source for our phone. There are some tweaks that can't really be made yet, and probably a bunch of wasted cpu time where errors and stuff get worked through.
GB battery life was worse than Froyo at the same stage of development. It'll even out better when we have the official kernel source for the DHD, I think.

So most ICS based roms have roughly the same battery life?
I'm current on the audacity beta, getting about 20 hours with no charge with moderate use. Gingerbread i could go about a day and acouple more hours.

I'm a bit bitter that I can only use 3G or higher on Bell with my DZ...that means if I want better battery life I need to ditch mobile data altogether. Boo.

Better battery life
All,
I was just about to install "Elitemod", which claims to be tuned to bits wrt battery life, and I noticed AudicityBeta1 was released.. so i thought Id try it out.. and
And yes I think its much better!.. this morning I used it a bit, made a dozen phonecalls, sync'd email and for the first time the "voicecalls" are less than the screen.
(see attachment)
Im wondering if the recently released qualcomm drivers made a difference..
At this rate it will last ~40hrs... probably less but as long as it lasts the day Im happy
Anyone else want to confirm my findings?
