Battery massive improvement after update?

I posted this on another forum... and got some positive feedback.
The update just miraculously increased my battery life tenfold!
I am 7 hours 12 minutes in and I am at 80% (using the battery indicator provided in settings, not by battery widget). I unrooted to install the update (yet it feels like I still have Herver's ROM). Brightness at 50%.
I didn't use the phone that much today (I had class), but I used it inbetween breaks and whatnot. I guess pretty light usage.
I think the update messed with the radio/wifi performance.
What about you guys?
Edit: I know people have gotten 20+ hours with ROMS, but this is without one.
Hopefully ROMS increase the battery life even more.

Hi patelkedar,
I can't speak for everyone, but according to myself and other users that have responded to my post battery life improvement has been absolutely astounding as of this update.

Blah. Sorry for double thread.
Search didn't go so well I guess.
Anyway, seems like everyone has seen major improvement.

Totally agree. My battery life has improved vastly. I came from fresh 0.3 and EvolutionX. I had excellent battery life with both of those roms too. But I unrooted to give htc a shot at stock again and I am happy. Phone has been off charger since 7:30am and it's now 3:05pm, with moderate usage and on wifi i'm at 78%. I don't know what I would do without my EVO. I love this damn device.

My battery life is phenomenal with the stock update. I was one of the ones who took the plunge and lost the ability to root for the time being but its performing so well I really don't care. They made everything run better and the battery was just a bonus.

unevoked not working after 1.4xxx update
I uninstalled the superpermissions and unrevoked before updating. now it will not root obviously. tried to install setcpu and various other programs but will not work. this sucks.. i see no difference in battery life or speed....a lot of people think an update is a good thing sometimes, but it is not. HTC should just release froyo 2.2

Pretty much if you have alot of Facebook friends the battery life savings will be huge with this update, also if you use a Flickr account battery savings will be huge, it seems they fixed the issue with Flickr causing 100% awake time as well but didn't mention it...crossing my fingers anyway, so far haven't run into the issue after resetting up my Flickr Account.
P.S. The update seems very much worth losing root for now as it seems to have fixed many things not metnioned and some functions are way faster now, going to manage applications loads in 2-3 seconds now versus 10-20 before etc... There seem to be alot of fixes not mentioned.

You guys mind posting your settings?
I'm at 9 hours and 40 minutes with exactly 50% battery remaining, but I haven't been using the phone like crazy. Some light web use and decent amount of texting all throughout the day. This is not an improvement from the pre-update era. Pretty much the same

HTC has released it already. It's Sprint now that has to smooth it over and make sure that it is compatible with their stock applications before releasing it to the masses.

Correction: Google has released it already. HTC + Sprint need to smooth it over and make sure that it is compatible with their stock applications before releasing it to the masses.

Phone also all around seems smoother in the sense UI especially. I'm enjoying my EVO again and actually using it as a cell phone now instead of a super-rapid-fire-rom-flashing addiction-device. Sometimes I forget that my cell phone is a cell phone and not a netbook (yet) lol. Cheers to HTC for the update!

Ditto. I don't miss the custom ROMs, honestly. I haven't had a single FC since this ROM launched and the device feels much smoother and faster.

Yet another battery issues thread

Yeah I know there are a lot of other battery threads out there, but just wondering if I can get some help from all you gurus.
Currently running MYN Warm 2.2 RLS3 with HTC kernel 2.6.32.15.
Have read a lot about this and done a lot of the usual optimizations (calibrate battery, turn off auto sync, 4G, etc...last test I did I was able to get about 25 hours on a charge with very little usage, which is pretty decent. So the phone seems to be sleeping the way it's supposed to.
The issue I have is that when I actually start using the phone the battery drains like crazy (about 1% every two minutes). This is with regular usage (i.e. internet browsing). If I use certain battery hog features such as Navigation or Bluetooh then it drains everything in a matter of an hour or so. Have tried playing around with SetCPU and don't really see any improvements (BTW I only get three options on SetCPU).
So the question is whether the battery drainage is a function of the Kernel I'm using? Why would it be good when it's sleeping, but as soon as I use something consumption goes through the roof. Is there anything out there that would allow you to see actual battery usage by app or service? I know Spare Parts gives you SOME info, but it's not granular enough (i.e. It says Android System includes many different pieces).

I doubt there's any magical kernel that can do more than what you are getting now.
Best you can do is to make sure the phone sleeps when the screen is off, which seems like you have already.
Max display on usage I usually get out of a charge is between 2-3 hours at about 30% brightness settings, out of about 12-15 hour per charge.
I sync google, always data on.

yo i have myn's rom as well but different kernel.. try the ones that myn added in the myn update app that came with the rom

Hmmm...so I guess 2-3 hours of actual usage is the best I can hope for then? I hear people saying how they get a lot of hours and that includes having Bluetooth on, browsing the web, Pandora, gaming, etc...If I did that with mine I don't think I would get more than 45 minutes.

You probably can extend it by using wifi but what's the fun in that?

Hmmm...Where? Are you referring to the Warm Updater app? I don't see anything about other kernels there. I haven't flashed any kernels on my phone. This is the one it came with.
What battery life do you get when you're actually using the phone?
Achllles: I get quite a bit of degradation on WI-FI as well.
I'm just trying to understand if there's a way to see what exactly is eating my battery when I use the phone. I mean I could be just sitting on the screen not doing anything and if it's on it consumes quite a bit, but as soon as I turn off the screen everything goes to sleep and consumption drops to about 1% per hour. just trying to understand this huge disparity.

Not sure. Best you can do at this point is to install current widget and see how much is being consumed, and guess what's killing your battery.
One other thing I've noticed was even at same settings, my phone often consumed around 25-30mA while screen is off, but now it hovers around 50-100mA, and I haven't made any change to the phone.
Not sure if it's effect on real life usage, but it does seem like it does.

Maybe its not software related...maybe your battery is just shot already.

I know exactly what your going through OP. This caused me to leave Myns and Cyanogen and go to Fresh ROM.
This seems to have mainly fixed the problem.

Myn was using the stock kernal, but his new rsl4 is gonna be using ziggys elite kernal.. Now is this kernal gonna be faster than other ones? No but myn told me its not about speed. Its speed that makes your battery life go down. These flashy kernals that have high quadrant speeds, suffer battery draining issues. So wait till friday for the new rom, and see how that goes.

there are 2 kernels there.. just try to look harder, i get 12-15hrs heavy use which is more than enough for me

Was never able to find these other Kernels, but I did install Netarchy Toast. Installed versions 4.19 to try Collin's Battery Tweak, but could never get that tweak to work properly (it always has a process that uses a lot of CPU). Uninstalled that and tried version 4.2 ant that seems to be working OK (without the battery tweak).
So after a lot of testing and re-testing I've come to the conclusion that my crazy battery drain only happens whenever there's a "radio" on. CPU usage is not the main culprit in my case as even overclocking it doesn't drain it much if the radios are turned off. It doesn't matter if it's WIFI, 3G or 4G, if the phone is using any of this it drains very quickly. Thus the reason it acts good whenever is sleeping.
A perfect example of this is that I used Power Amp to play music from my music library (from my SD Card). Used it for like 4 hours and it drained the battery at a very reasonable pace, then I stopped that and started playing music using Pandora. Immediately the battery started to drain at about 1% rate every two minutes or so. I've read somewhere that using WIFI instead of 3G would save battery. Didn't seem to make a difference in my case as it drained at about the same rapid pace. Now if I have both on, then it gets even crazier.
So having found the culprits the question is whether there's anything that can be done to improve this. BTW I think I have the latest PRI (1.77_003), PRL (60671) and baseband (2.15.00.09.01) versions

Wholy crap gingerbread has awful battery

I wouldn't even say I use my phone frequently. When I used the miui or however it's spelt rom I would have 60 percent to 30 remaining each day. On gingerbread? I'm down to 15 percent every day and every night my phone has shut off due to lack of battery.
Isn't there any rom with excellent battery life? That's all I want, I use my phone for tethering.

i put CM7-RC2 on my device yesterday and it's the best battery life i've ever gotten.

Gb battery life owns, u got something else going on

No he doesn't, i've measured religiously since the original nexus shipments and this is by far the worst

My battery was really bad but now it seems to last me 10hrs & up which is weird for a phone to last me that long. I really think theirs an app or bug running the battery crazy I don't use any task managers. Their was a thread somewhere saying to run your phone on recovery mode and to press on the reboot/restart and battery get better I did that so maybe it does work but I highly doubt it.

I can vouch for poor battery too. I am on CM7 RC2 and I can't even make it through a day with light use. By light use, I mean practally not using the phone at all.

My battery life seems to be better than ever. Some 10-20 percentage units more left in the evenings all down the line.
Edit: Stock GB, no task managers.

I agree. Gingerbread has been nothing short of AMAZING for my battery life. The battery life is so good now that I stopped using my spare battery altogether!

Did you happen to do an Update or a full install when you got gingerbread?
Some suggest that it's due to the update process.. so you might want to try a full install:

Remember to wipe your cache first..

What i noticed is taht custom roms use more battery than stock rom. this is for me i don't say that it is like this for everyone. But with gigerbread i got the best battery life. i also think using apps from SD uses also a lot of battery life, but again i have no other choice to low on memory.

bug
I had the same problem. I am on stock gb.
Just set wifi sleep policy to never. It will last 2 days after that. It is definetly a bug.

Seems to be a real mixed bag with GB on N1's. Lots of people saying "better battery" many others, myself included, reporting much worse. For me, I experienced very poor battery life right from updating to the stock GB using the singned passion .zip file. Even did a factory reset, and only reinstalled my daily used apps and it made little difference, then I went back onto a MIUI rom for a few days and battery life was wonderful again.
Then early this week I flashed to CM7 RC2, and for two days battery life was the worst I've ever had.
Had been seeing a few comments on different forums of people who had the same problem swearing black and blue that after they changed the wifi sleep policy to "always on" their battery life improved dramatically on Gingerbread.
I know if sounds backwards, and that is why I was sceptical for ages, but last night I made the change to see if it would make a difference for me today and all I can say is WOW!!! Phone had a real test today as I started work really early. As of right now the phone has been off charge for 16 hours.
Half a dozen or more voice calls, minimal text, my usual wifi and 3g data, about 10 min of streaming video over wifi and about 1/2 hour in total running Navigation.
There is no way in hell my phone would have done all that and even lasted me 8 hours prior to changing the wifi sleep policy - so I think there is definitely something in it.
As for the ppl who aren't noticing bad battery, maybe they already had theirs set this way - or maybe it's an issue only effecting certain batches of devices (like the wifi reconnect issue which seemed to be pretty common pre froyo)

it /WAS/ terrible at first. Really, really dire, but it's back to what it used to be, even better now perhaps.
To the OP, do you have WIFI turned on still? I used to leave it turned on and it didn't ever knock down battery as it was going to sleep and not coming back, so wasn't a drain. GB appears to have fixed this, and it was staying on, thrashing the battery.
Turning it off and turning it on as needed only, battery life is now fine.
Do you have WIFI Turned on? Bluetooth? For now, to try and test what's happening, turn off 3g, wifi, bluetooth, automatic date/time sync, and JUST use it as a phone for a day. See what % you're at at the end of the day.
Then we can take it from there.
But I'd be pretty certain that it's wifi related, in that it's now working as it should be, we just got used to it being broken before.

My phone on cm7 rc2 has worse battery than I used to have with wildmonks kernel and cm6.1. Yesterday, the phone was barely used until 8 o'clock at night. It was at 45 percent. After an hour medium use, its gotten down to 23 so I had to plug in the phone....the easiest fix? Keep a charger In the car!

Using stock Gingerbread and I can say that my battery life is decent, better than Froyo for sure. The phone lasts longer than 16 hours and I use bluetooth to listen to music for 1.5 hrs on my commute home. By the time I get home after a long day (8pm'ish), I still have about 20 to 30% left.

I have no wifi no bluetooth no gps and a dim screen.
Tis is seriously crappy battery life.
Does anyone think they can link me to a good miui rom. For me, it seems that gb just wont work.
I am running stock gb then i flashed the root and my boot loader is unlocked.

Listen to this person!
For some reason, since 2.3.3, if you have your Wifi policy to sleep when the screen is off, Android will rip through your battery. You'll notice Android OS taking all the battery on the status page.
Set the sleep policy to never and you get better battery life again. Turn off Wifi manually when you're not using it, even better. Until somebody fixes this bug, I guess it's the only workaround we've got.
More info: check issue 15057 on code.google.com - cant post link due to the newness of this account.

Same here on shorter battery life my nexus one as well post gingerbread ota... I will look into detailed system processes and try to find out why...

Log into latitude and log out. Every time there is a map update it defaults to being a battery draining monster. But in essence. Something to do with maps link to latitude (which i don't even use) breaks my phones battery life.

[Q] Do you have battery problems with SwiftDroid RC5?

Hi! I wanted to know if you guys have a problem with the battery life on SwiftDroid RC5. I have a poor battery life and therefore big battery problems.

i had mine and bought a new batt no probs after that

Yes, I do. Since RC4 and RC5 I have very poor battery life. Before it was enough to charge once every other day, now I have to do it daily.
Actually after installing RC5 it was a disaster as battery didn't keep even 24 hours but after recalibration it's better. But even then during the course of the day while doing basically nothing (say, sending and receiving 3 or 4 sms) it goes down from 99% to 40%.
Edit: I should mention that I overclocked to 800MHz, but I used to do it before RC4.

Same here. I'm moving on Cyanogenmod 6.

yeah swiftdroid is a real battery drainer but
on swiftdroid on average my battery lasted 2 days..
but still i use cyan6!!
good in battery and performance!!

Same here. Experiencing battery problems on SwiftDroid aswell. Like mentioned above the battery drains even when doing nothing. Experience this on basically any mod built on SwifDroid ofcourse. Changed to EleganceSwift, waiting for mike to release AOSP with Bluetooth-free radio ;-)

There's something more to it.
Recently I was playing a bit with my phone, installed couple of applications and then suddenly I realized that battery doesn't drain as fast as it used to. One thing I noted is that for example Videos application doesn't reside in memory anymore. I'm not saying this one was the sole battery hog but I'm starting to suspect that those cases of battery going down very fast may be related to some misbehaving app or apps and not necessarily be Gingerbread's fault.
If that's the case, the solution would be, I imagine, to trim system preferences to have such apps killed fast not to let them stay active.

using ASIS atm, but when I was using RC5 I didn't notice much faster draining. Still, it depends how many apps are running on your device and did you overclock it? I used to have min 250MHz, max 600MHz and it was pretty fine with texting, multiple apps running and music. Now with min 825MHz/max 825MHz it's draining faster ofc

Well,I remember a day when i update to SwiftDroid RC5, the batter drains and there isnt any app running in background after that i changed to a another rom.
btw fdespotovski, Multiverse is my favorite rom, in fact, i wrote on the offcial blog but i have problems with the RC3, statusbar sound widget doesnt work properly for now im on RC2

I'm not using ASIS, still at RC5, and what I reported is that both RC5 and RC4 drain battery much faster than earlier versions. Assuming ASIS is just cosmetic change to RC5 it doesn't surprise me you didn't notice any difference. And again, I do overclock to 800MHz and I do it since M5 if memory serves me well. I know principles of overclocking and I know, and accept, drawbacks that come with it. But when at the same clock RC3 can live two days or more while sometimes RC5 barely manages only one then I suspect something is not right.
I tried to check which applications are responsible for battery drain but system report is not helping when telling that 98% took Android system, 2% cell standby and 2% phone idle.

Sorry for necroposting but I didn't want to litter forum with new thread and the problem itself hasn't go away.
I'm still using SwiftDroid v2.0 RC5 and until recently I still had problem of battery barely keeping one day: whole night on the charger and after moderate to no use during the day on the evening it was almost drained.
Recently I installed one more application (rather unrelated, I'd need really solid proof that CPU Spy directly improves energy usage) and after that the battery easily keeps for two days. Which brings back the theory I have that the short battery life is not necessarily caused by Android itself but by some applications staying in memory and not sleeping properly. If so, installing extra app may help just for this reason that it having higher priority will swap out those misbehaving ones.
Thus I propose little hunt, if anyone's interested. I'd like to stay focused on v2.0 RC5 (maybe RC4/ASIS if you believe the difference is not too big). I need reported both GOOD and BAD battery life. In either case please write down all apps currently in memory (you can skip those you have installed, I'm mostly interested in what comes from ROM). And don't forget to mention which actual version do you use and whether it's good or bad case.
Given some meaningful data I hope to isolate which apps cause excessive battery drainage. I'm not sure what to do with that information next but I think it would be good start anyway.
To make said start, here's what I have:
SwiftDroid 2.0 RC5 / GOOD battery
- DSP Manager
- Usage Timelines Free
- Doit.im
- K-9 Mail
- Auto Memory Manager
- Superuser
- Settings
- TM World Clock
- Go launcher EX (doesn't report itself as staying in memory but I suppose it has to be running somewhere)

Guys help please, I have a battery/charging problem after installing RC5, this is my first ever custom ROM, it worked great yesterday, but after charging it over night I'm stuck at 99% it won't go up nor down, the phone won't charge and it won't even connect to PC via USB I tried turning it off completely and then plugged in the charger but it just booted up (is it supposed to do that this is my first android?) and that was it. Everything else works fine, wifi etc.... Is there a way to fix this ? I can't transfer a new custom rom to the sd when it won't connect to the PC

the battery stuck at 99 % is a often coming bug and i don't know any solutions mine goes to 97 % ...
ehen phone is shut down and you plug the charger its normal that its booting(because of fastboot)
connection to pc should work, try another port re-install the drivers

thanks ...............

I also have a battery problem... i have installed this ROM 3 days ago, and now i can't charge my battery over 45-55%. Phone was charging all night long, and batter lasted for a day and a half, but its annoying... btw, what now, do I delete battstats now at 55%, when i can not charge phone to 100%?

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..
Sent from my HTC Vision using XDA

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?
