Yesterday I flashed Franco's Kernel along with his app. I am running CodenameAndroid 1.6 ROM with Franco's Kernel r135 nightly.
I haven not been getting the exceptional battery life that everyone has been raving about. I understand every phone is different, and there are tons of contributing factors to battery life.
I have my screen brightness very low, location services are off, no LTE running (I'm running on 3G), however I've had wifi on all day today since I am at home. I've undervolted by using Franco's paid app and am running On Demand governor. However, I have generic hotplug turned on because I'm not always on my phone and messing with it. It's 1 o clock, and I took the phone off the charger at 8 this morning. I'm already down to 79% and my on-screen time is only 18 minutes while my idle time is 3 hours and 44 minutes. Other than that, I don't have any apps unning in the background accept for the regular things that should be running.
To the point, am I doing something wrong? It just seems weird to have that much battery drain and have my phone on idle for almost 4 hours and on-screen time to only be 18 minutes. Are my expectations too high for this kernel? I've heard awesome stats as far as battery life goes while using this kernel but I'm not seeing it. Is it because the kernel hasn't fully "baked" into the phone like some people say? I appreciate the feedback.
That doesn't sound right. Do you have BetterBatteryStats installed? That way you can find out what is keeping your phone awake whilst your screen is on.
Also, what are the rest of your kernel settings? Mine:
r135-512
384/1228
interactive (no hotplug works best for me)
I don't uv, but let SmartReflex do it's job for me.
This works best for me with BAMF (atm, but switch beween that rom and Liquid quite often). BAMF gives me best screen on time, but idles less good than Liquid, which gives me less screen on time. On a day of heavy usage, BAMF wins.
What I'm trying to say is, find your zen in rom/ kernel/ radio combo, because you might just use your phone differently then me (and others).
Oh, and I use the Samsung oem 2000mah battery. That helps too. I'm getting ~10h of use with ~4h screen on on a charge.
Hope this get's you on your way mate

Hey guys, I am on cm 7 nightly #11. I am on radio 09.01 and have experimented with Chad's and the stock kernel.
I have background data, auto-sync, wifi, bluetooth, gps all off. I dont have facebook or anything pushing either. Screen brightness is on about 60%.
With the seido 1750 mah battery, I am getting around 7-8 hours of battery. That is to the bone dead .
That is making maybe 1 call a day, a couple dozen texts, browsing the web a bit and listening to an hour or so of music/pandora.
In spare parts it says under 'other usage'. Running 42.7%, screen on 23.8%. 'Partial wake' only ones on here are really music and pandora, but they are relatively small slivers.
Under settings it is 68% display, 8% cell standby, 7% voicecalls, 4% android, 4% idle.
I have tried wiping battery stats, doing the drain all the way technique, etc.
Anyone have any suggestion on what to do here?
Thanks.
I'h suggest moving to Cymod 7 RC1 (unless you mean the new nightly, then I'm not sure) I have been running cyanogenmod since before the nightlies hit and I've never had battery that bad. I get about 3 days of standby out of my phone on RC1 and the incredikernel. I listen to pandora on 3G (charging only in that time) about an hour a day and never charge otherwise unless I'm using it heavily. I text semi often, but don't really listen to music or call.
Seems wildly different that my experience. I take it this is specific to this rom, and your battery is better on others, ie battery itself not going south? With pretty similar usage and syncs to yours, I make it about 10 hours to use 50% of batt while at work. That's with stock battery. Only new nightly #8 with stock cm7 kernel.
1) change to 2.15 radio
2) did you buy the battery off ebay for $10? If so its really a 1250mAh or so. Either way OEM batteries are better than the aftermarket (ie Siedio)
3) Is the battery really old? If so it may be wearing down
4) Kernels are all decent, they should all get better than what you are getting...
5) Don't overclock to 1300+ it should run smooth at 998 or whatever it is.
I get 12+ hours of moderate use out of my OEM 1500mAh battery.
When I first started on the nightlies and flashing different kernels, I was having the same issue.
I stopped flashing other kernels and started using the stock cm7 kernel, now I am getting awesome battery life. Also, after flashing, several people recommend immediate rebooting to improve battery life.
Thanks guys.
Few questions.
1.) Radio 2.15? I am on 2.15.00.09.01 currently. Is that the same?
2.) Mine is an authentic Seido. But should I start using the OEM 1300mah battery?
Oh, I should mention. I don't overclock at all.
I was using the stock battery and got ~6 hours even with UC to ~850 most of the time and ~200 while screen off. Turns out my battery was defective and even now OCing to ~1100 most of the time I'm getting 4x the battery. Of course I couldn't be sure that my battery was defective until after I bought the new one but if the battery life just doesn't make sense then you might want to try going back to stock (assuming that's fine) and comparing.
try a different battery maybe
i currently have the stock battery which was only used a couple days
a HTC 1500 battery
a seido 1750 battery but i havent tried any of the other batteries in awhile but i also use CM7 nightlies on #11 because it seems to have best battery life
maybe ill try my other battiers and see my findings
I've had a similar experience and I'm fairly certain it was not my battery. The battery worked great with other ROM's; Normal usage of my phone would yield roughly 40% remaining battery life at the end of the day.
After going to CM7 (I started at #38) my battery has been lousy. I can't get through a day at all.
Two days ago I flashed incredikernel 2272011 as well as CM7 build #11. I'm using the default smartass governor and my battery performance is back where it used to be. Going through an entire day for me is no problem with normal usage.
Not sure if that helps but I've had good luck with this kernel thus far. Oh... and phone has been rock solid!
I'm on CM7 Nightly 11 right now with stock kernel. Seidio 1750 that I've had since last June. I've recently been comparing Tiamat's 3.14 to stock. If I'm on any kernel that has Smartass I'll use that as my governor. If I'm on the stock kernel then I use SetCPU with the kernel set to ondemand and a screen off profile set to 245. Either scenario seems to give me pretty good battery life, but I think Tiamat's with smartass may be a little better. With any kernel I've had it overclocked to 1.03.
Also, the brightness settings based off of HTC's ROM that were posted in the cm nightly thread in the development section have worked great. I've definitely noticed an increase in battery life.
I use advanced task manager with the shortcut on the desktop. I leave essentials running in the background but try to make sure everything else is killed.
All in all with the current setup I have I can get roughly 12-14 hours with heavy texting, 4-5 phone calls, internet and games scattered throughout the day.
Hi, I was wondering if it's typical for the Evo's battery to take a rather large dip upon unlocking it after not using it for awhile but keeping it on. Around 15% under within the few minutes that I used it after waking it up from maybe about 4 hours or so of not using it and just keeping it locked without any phone calls or other disruptions.
Why does it seem to want to ramp up something like crazy when turning the phone on after not using it for awhile? Or does it actually need to do that to function? Thinking about trying out the conservative governor and jacking up the minimum MHz so the performance isn't horrid.
Using CM7.0.3.1 with SZen, have tried the SZ, smartass, and InteractiveX (current) governors.
Radios and what not are all up to date.
Trying other governors doesn't seem to help this issue at all (if it is an issue).
tried a reflash? I think i had some battery issues the first time i installed CM7. I currently use SZ 2.1 i think with SBC and BFS. My governer profile is set on savagezen and I get pretty good battery life. My phone never has huge battery drops unless I'm using the ever living crap out of it.
Nah, I had a 100% clean flash two times over, I reflashed last time for a different problem which was fixed because i was messing around with settings, not from the system/kernel. I mean I could reflash it again but I've had tons of clean flashes and always have noticed the issue, now that mostly everything else is fixed for me I'm getting around to this issue to see if it even is one.
Same problem drops 5% with in 2 minutes, I've calibrated tried cm7, miui, and stock they all do it...even bought a new battery...

Mine doesn't necessarily drop a certain % in a certain way/timeframe, just a large dip after not using it for awhile. As if it's taking an enormous amount of resources to try and wake itself back up and stay awake after being asleep for so long.

I switched to a SBC kernel and fixed this issue. used to drop from 100 to roughly 85 % in as little as 10 min off the charger
did you re-calibrate you battery stats???
This is w an extended battery and an amount of usage today...its all about finding the right combo.
I reset battery stats every new kernel/ROM I change. Is it useful for any reason to reset after switching governors? I'm going to try Tiamat next probably.

I use SZ as well, doesn't help it.
Or rather, there's no immediate drop like i said for me. Just quickly depletes after a long wait.

What do you use out of curiosity? I'd love for mine to have a steady drop like that instead of a massive dip, 8hrs on a very decent amount of use too. Even with the extended battery that seems like so much. Unless the extended is literally double the life?
All,
I wasn't going to root my baby, but yesterday was the first time I out for the full day without being able to charge and was bout dead by the 10th hour. I took Wifi off and left it on 3g.
So after that, I decided I'm going to root and load up a ROM hoping one is going to give me a bit better battery life. Which one out right now can provide me with good battery life and stable.
Thanks for any info.
no rom is going to drastically improve your battery life. For the most part this phone can get anywhere from 3-4 hours of screen on time

Undervolting is your best bet imo.
I am using a GSM Galaxy Nexus running MCR lr8 with OC/UV kernel and after undervolting I get between 18hrs and 30hrs depending on use (overclocked to 1.4GHz). Note this is my normal use, where I am also doing other things during the day - not in "just got my new phone so am playing with it all the time" mode
30hrs is the absolute max and I doubt I'll ever get that much again unless I purposely don't use my phone at all!
The main thing is how low you can UV it at 350MHz and not have any problems, then set the CPU to stay at 350MHz when your screen is off. Together with JuiceDefender or a similar battery saving app, your battery will seem like it lasts forever when the screen is off* - exaggerating slightly of course.
*unless you have a misbehaving app keeping the CPU or data connection active, like I did with Twitter last night. I shall be disabling auto-updating for Twitter now.
Note: I accept no responsibility if you damage your phone by undervolting or doing anything else!
dont look anywhere else
http://forum.xda-developers.com/showthread.php?t=1402341
no custom kernel or modem required
flash it as stock, and watch the difference!
if you don't want to root,
try juice defender...
i got it on my GNEX and it is just simply awesome.
read through the tutorials and go from there.
i've been getting stellar performance.
I got pretty crap battery life yesterday (see attachments). I plugged in my phone in the afternoon so it was fully charged when I left work in the evening, and then I only used the phone a little bit before I went to bed.
From 6 pm to 11 pm (when I went to bed) it drained from 100% to about 55%. Didn't plug it in overnight. When I got up this morning, it was at 17%. Wifi was on, airplane mode was not on, but I didn't use the phone at all and it probably should have just gone to sleep, right?
Anyway, this was only my second day of using CM7 instead of CM9. I had been on CM9 for a week or so before I decided to go back to CM7 for the battery life. It's weird, I've searched for and read several of the battery life posts here in the Q&A section and everyone seems to recommend CM7 for battery life, but in my case it didn't work out so well. There must be something going on - how can I figure this out?
I'm getting great life from cm7! You may want to wipe all caches, and battery stats, and reflash the Rom on top. Then apply v6 supercharger, kak tweaks..
Further more download better battery stats, Google search it, and see what apps have high partial wake times

v6 supercharger, tweaks, etc... isnt required at all.
He needs to show us all his battery stats from Better Battery Stats, and his CPU freq Table from Voltage Control and the I/0 Scheduler and Cpu Governor and What kernel is he using
My kernel is listed as 2.6.35.7 which I believe is an AOSP kernel
I don't own Better Battery Stats
Just installed Voltage Control... Min 100 MHz, max 1000 MHz, I/O scheduler is sio, CPU governor is ondemand, and this is after running the V6 and KAK scripts. I'm going to see how my battery holds up today.
Try with better battery stats app

you can also use cpu spy to find out if your phone is actually going into deep sleep or if it's running @ something higher.

BBS is free and is on XDA, Try conservative for your CPU governor that'll help and if you use CPU Spy as mention below me that'll show the amount of time each freq. is on
Ah, thanks for pointing that out!
I'm going to take some time to figure out how to interpret all this. CPU Spy seems pretty straightforward though. It is reporting that the CPU has gone into deep sleep most of the time it's been unplugged, so that can't be the problem. I did go into Voltage Control and change the CPU governor from ondemand to conservative; hopefully that helps.
For Better Battery Stats I'm going through the official thread and just trying to compare my results against what people are saying there. So far the biggest potential culprit is GTALK_ASYNC_CONN, which has the largest duration of partial wakelocks at 2m22s. Behind that is Wimax (obviously having that on is gonna drain my battery; I don't normally use it but today I have been) and then *network-location* with 1m14s. I'm not sure I really need to post a full dump although if anyone really wants to look it over I could.
Anyway thanks for all the help guys.

In BBB look at since unplugged and kernel wakelocks do you have a "mmc_delayed_work" mine is high that affects battery life too
Slightly different situation now. A couple days ago I switched to an ICS rom, this time AOKP. Things seemed to be fine but this afternoon my battery absolutely tanked while I wasn't using the phone - the standard battery interface showed that the phone did not sleep during that time even though it was in my pocket, and Better Battery Stats showed a huge amount (over 3 hours) of kernel wakelocks from "sec_jack." Know what could be causing that?
EDIT: I should add, using the standard battery screen, it has simply lumped in whatever is now draining my battery into "Android System." It showed a keep-awake time of around 20 minutes when the total time unplugged was 25 minutes. I tweaked a few things, turned off AOKP's weather service and made sure Facebook wasn't pulling background data, and restarted my phone. I'll have to see how it goes.
Solved! I turned off the weather service built into AOKP last night. This morning, the sec_jack wakelocks were gone and my battery had only gone down by a couple % overnight.
I'm looking for a rom with really good battery life.
I am currently on AOKP build 40 with franco kernel milestone 4.
I get about 2hrs screen time and my phone dies in around 8 hours.
I have my brightness set to zero, phone on silent, i do some texting through the day along with using twitter, i have LTE turned off and im at a spot where i get good 3g, wifi off, NFC off, and pretty much everything set to off that could negatiley affect the battery in anyway and juice defender installed with the aggressive mode on.. Accounts and sync is also off. My governer is set to Conservative all the time, same with my franco governer thing is on power saver. I am underclocked to 729mHz.
Idk maybe im expecting too much from the stock battery, but jeez shouldn't i be getting a little better battery life? Haha i also calibrated my battery too
Anyways could you guys give me some suggestions on what Roms i could flash and kernels, that would help me get a nice amount of screen time and battery life?
I'm a fan of bugless beast
Ymmv
All I have done when I bought phone, is getting yakju 4.0.4 & root and installed franco's kernel.
Phone usage is 17h-1d and display on time 4h - 4:30h.
Greader, twitter, 2mail acc's, weather, viber etc. etc. all on sync over wifi mostly.
When I use 3g connection mostly usage is arround 15h and about 3:30h of display.
