I'm on toroplus. Preferably Jellybean. Well here are the ROMs I've tried.
Black bean baked is causing extreme battery drains. Cleared battery stats and did a calibration and nothing.
I have a Hyperion Extended battery 3500mah and I am getting a battery of 50 minutes screen off/on.
Thanks and do not flame.
BAKED is causing battery drain? That way improved mine. Stock kernel. Try ru jellin. Basic stock, no mods but extremely awesome right out the gate
Stock

To be honest, kernels are all about same right now battery wise. It also depends on which ROM you use. I never tried Baked, so I can't recommend best kernel for that, but what I can say is, if you don't need color control, overclocking or anything like that, just go with Stock. It's most reliable kernel out there
If you do want extra features from the kernel, just try them all. Make sure that you use them for about a day or two for battery life.
Me personally am using AOKP nightly with Franco Kernel (Latest nightly), overclocked to 1.4GHz with stock battery (GSM) and still manage to get about 4.5 hours of battery life
Stock rooted.

Didn't see anything specifically pertaining to this by doing a search, so I decided to start a new thread.
I am currently running the MIUI rom along with netarchy's universal 4.1.9.1 (the less aggressive UV because aggressive caused screen tearing). Battery life is good, and better than with the stock kernel, but I still only see about 8-10 hours under light/very moderate use.
Does anyone have a kernel they prefer for exceptional battery life? I'm not looking for crazy, 1.5GHz overclocking or anything like that; superior battery life is most important to me.
I'm using Savage v1.6 CFS - HAVS - WIMAX (#6 I think).... and I am getting crazy battery life. Normally around 25 hours with moderate use.
Never been happier with my phone.
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.
Hello I just flashed my phone to CM7 and it's so smooth, but I was wondering if I could get the.most our of my battery by using a different kernel. That allows everything to work. please help.

Tiamat kernel plays nice.
It can also be undervolted additionally.
Right now I'm running CM7 Stable, and I use the Savage Zen kernel (no SBC). I get pretty decent battery life out of it by using SetCPU and setting it to 245 min/max when the screen is off and around 245-1000~ when it's on; this allows me to get great performance while still maintaining decent battery.
savaged zen 2.0.0. my phone's been through 2 nights. played quite a few games. checked facebook a bunch. used flashlight a few times. email, xda, calls. 1 day 11 hours and still like 10 percent left. runnign on savaged zen governer. that's pretty damn good.
then again, i did fall asleep wiht it on and not charging twice. at least we know it sleeps well...
played with the SZ governor for a little bit the other day, and found it pretty nice.
ended up switching back to tiamat and smartass though.
also currently testing and trying out SBC just to see how it behaves. easily noticing that extra percentage of battery that gets pushed to charge due to the trickle charge vs a non-SBC kernal.
I'm visitng here from the Samsung Captivate forum. I flashed CM7 to my girlfriend's EVO last night and she is experiencing horrid battery life. I turned off the "back up to google" options in the privacy menu that is said to be starting Android system every time the dialer is used, which is said to use up excessive battery power.
I'm about to flash tiamat's latest kernel. I'll report back on how it goes.
I flashed back to CM7 the other day. I was having issues, so i completely reformattetd everything. Went back to stock, unrooted, re-roooted, and flashed cm7. I'm getting great battery life with CM7 + the tiamat kernel.
As of right now: 25 hours, 19 minutes of uptime with 68% of my battery life remaining.
ETA: This is using the 3500mah seido extended battery.
My girlfriend is getting much improved battery life with tiamats 3.3.7 kernel

i'm on Kings Unleashed GBR3 NEON-CM7 using tiamat 3.3.7 sbc kernel and i love it! i am getting almost 35hrs on one charge!
Been using the 2100mAh since I got my Vzw Nexus. Yesterday, I had it on WiFi at home with a solid connection all day with sync off, maps disabled, and GPS/Bluetooth/everything off. I got 2 hours and 53 minutes of screen on time at 30% brightness. With WiFi on entirely and 5 bars of it...I would expect closer to 4 hours of screen on time...and I would see that back during the ICS days. Currently running Rascarlo with Trinity a67.
Think its time for a new battery? This is by far the best ROM and Kernel combo results I've seen on terms of battery life. How long do you guys keep your batteries for?

I've had my battery for quite a while running CM10 + Franco Kernel. The newest Franco Kernel when it comes to battery life is INSANELY good, I was starting to think the same thing as you but man... Franco Kernel changes my battery life and it barely ever drains.
You could try a different combination of kernels to see if it helps. And there is a method to doing a full charge (google it) something involving fully draining it.
Do you have any wakelocks? use the app, BetterBatteryStats to find out.
Debug your phone before throwing money away towards a new battery.

I appreciate the response. I use BetterBatteryStats, GSam Battery, CPUSpy, and AutoStarts (for disabling everything related to Maps). I'll try out Franco's new kernel. Thanks for the tip. I've been stuck on Trinity for a while...perhaps it is time for a change. Which ROM are you running if I may ask?
Edit: Which Franco kernel were you referring to? His latest nightly 290 or his latest Milestone 6?

Batteries last about a year charging once a day. If you run your battery dry a lot, expect to change sooner. My battery rarely goes below 40% and I try not to let it go below 10% when it does. I fully expect a year and I am @ 10 months. If you run it below 20% often I would say you probably need to change it already. YMMV of course.
...
Is there any other way we could check to see battery health? I know in better battery stats under 'tests' you can see it says battery health is 'good' but is there any other way?
Possibly max and min voltages? Ie fully charged ~4200mv and fully drained ~3500mv

You're looking for an app that compares designed capacity (1720mAh? I don't even know how much our phone has..) with actual capacity (which would probably be around 1500mAh after a year). I don't know of one, but if it helps, that's what you're looking for!

What would be the best ROM for battery life? I'm using CyanogenMod atm and the battery life is decent. If I flash Android Rev. would I sacrifice battery life and if so by how much?

Battery usage is completely subjective so what will be awesome for one may be absolute crap to another. Only way you'll know is to try it yourself

As mentioned, battery life is completely up to your usage. Some steps to try though which can be used across any rom is to give Rom Cleaner a shot and to use Greenify. This will rid any rom of bloat that could be sucking up battery and better allow the device to enter deep sleep where the real battery savings are had.
A well optimized kernel would give you some savings as well. I can personally say that on ARHD 5.5 with Elemental kernel .15 I'm seeing about 70% battery left at the end of a normal day. For me though that may only be one 20 minute call and an hour of screen on time. Even when flashing and messing with tons of settings for hours, the phone has never reached a critical battery level for me. I
It's more about the way you optimize (or debloat) your phone , than the ROM you are running. Use battery monitors like GSam or Battery Drain Analyzer and freeze apps that are causing you huge drain. Greenify is also good. Ideally on the M8 you can expect around 6 hours of screen time if you're optimized correctly.

This. I am able to get about 6 hours on stock, ARHD and Insertcoin. With power saver on, that ends up around 7-8 hours of screen time. Coming from a Nexus 5 that got 4 hours typically, I'm pretty satisfied. I'm inclined to believe ARHD will get "slightly" better battery life than CM since it is based off the stock ROM on the M8.
Generally the OEM skinned roms have better battery life and benchmark scores opposed to aosp. Happens all the time on Sammy phones and HTC apparently too. Posts above mine cover most you'll need to know. Its all about optimization and frankly that part is extremely fun and especially rewarding IMO. Gives me an idea for something like a community made thread on different battery tweaks/voltages :good:

I'm currently using Android Rev. 6.1 odexed (using ART atm) with ElementalX 0.10. I don't know if this is a placebo effect or not, but after flashing ElementalX(with default settings) my battery life seems worse :/
