So guys, what are your experiences with different rom's and kernels considering battery life? Which one broke the record?
Stocklite works very well.
For how long?
On 2G/3G, with gps and wi-fi on or off?
Indian stock its amazing best battery life and performance

I usually keep 3G on, gps and wifi off, and my cpu speeds set to 480 max, 245 min. brightness slightly turned up, no animations. Lasts pretty much the entire day with casual texting, phone calls and browsing facepunch
There is no term like "BEST" battery saver in custom ROM department. My configuration is in my signature. Gives me good battery backup. However, I am missing the stability of stock. But, I also hate the fact that S2E doesn't work on stock.
Battery depends on how much usage you give your phone. I follow what I posted on my signature and I get good battery life on any rom I use. As much "optimized" battery life might be on a rom or kernel, it won't matter. 1350mAh will only last as much as you use it.
hey guys - need an answer to solve my neverending search to this problem
i'm trying to determine the best way to get as much battery power out of my SGSII and i've been experimenting between a SGSII and a Motorola Photon 4G. both phones are running a ICS-AOKP rom, same CPU clock settings, both on "conservative" governor, and both on power save mode..
the only significant difference is with the battery and the kernel, while the photon is running with a stock 1700Mah battery and stock jokersax CM9 kernel while the SGSII had an 2000Mah Extended battery with Siyah 3.0 (with "battery" kernel tweek on)
at the start of the experiment the SGSII had 73% power while the Photon had 48% - i plugged in both phones to the wall and ran a game of order and chaos on both for about an hour and then checked back on the battery power.. the SGSII had drained from 73% to 45% while the the photon 4G had actually charged from 48% to 62%
i've tried a similar experiment with not only AOKP but also CM7, CM9 and MiUi and MiUi V4 and both yield similar results
now my question - if both phones are using the same rom with the same settings practically speaking, with the SGSII being slightly more optimized towards battery performance, why is it that the SGSII's battery will still drain while the photon 4G's battery will still charge?
Wow, i haven't had battery drain like this, give it like 4 battery charges then you'll see whether you still have this problem or not
I can normally get near enough 2 days battery life with medium usage. I'm using the stick battery MIUI GB
wow dude, are u using the stock battery or an extended?
always calibrating ma battery everytime it gets to 100% and it doesnt seem to help much -
Id love if someone else attempted the test by plugging in the phone and having wifi on + run a quick game to see if your results are the same as mine.. the typical response i get from others i've shared my result with is "duh - the battery will drain if ur playing a game while charging, all devices do it" but i have to ask "then why is it that this doesnt happen to the photon 4G?" i remember going on the samsung thread and someone mentioned that the board is set to absorb a charge that is less than how much the Chipset consumes
i am planning to flash an aosp rom on my GSM evo(s-off,unlocked).what do you suggest.ia have tested this one (http://forum.xda-developers.com/showthread.php?t=1551746) but battery is the worst ever.barely 4 hours of using.
i would love to see your suggestions for a ROM with good battery and camera working(2d,i don't really care about 3d),also jelly bean would be better than ics but ics it's ok too!.
thanks!
As a rule of thumb sense roms tend to have better battery life and aosp roms lack that. However there are a number of ways to help save juice on your phone. Having your phone CPU governors behave in a way that saves battery power when your screen is off. Don't overclock your cpu. Smartass governor is a great balance between battery and performance. Disabling apps that misbehave. If both CPUs are online, you can force the other offline when not in use or screen off. Not having certain features running in the background like auto sync, GPS and Bluetooth. And of course there's always that extended battery.
I have been using MeanRom and MikVirgin off and on. I like MikVirgin alot better, and want to use it full time, but the battery life is terrible. MeanRom makes my battery last at least twice as long, but I get worse reception. I read somewhere that the great battery life has something to do with turning off one of the cores while the screen is off. I'm not an expert, but i think that is a kernel issue.
Is there a kernel that I can use with MikVirgin that will give me battery life similar to MeanRom?
That's a relatively hard question to say which kernel gives good battery life. Because no one kernel by itself can save more battery life than the other. Some do handle the tasks and compliment the CPU better than others. It all boils down to how your kernel is set up, what governor you use when your screen is on. What frequencies on and off, overclocking the CPU drains battery quickly. Having both cores online and one off when screen off. What I/o scheduler in combimation with a governor. It really depends on how you use or phone to best suit your needs, not one combination is best. While maintaining good battery is a must sometimes you end up sacrificing from performance and your phone suffers with lags. From these experiences I have found that the cool kernel and the forbidden kernel give good balance and stability in most sense roms. Along with meanrom and common sense. Those two roms I have found to give good bettery life. You just got to experiment. While one combimation of Rom, and kernel work for one persons EVO may not be the same on another persons.
What has been people's experience with battery life with the different ROMs? I've been on AOKP for awhile, and the battery, quite frankly, sucked compared to stock. I'm currently on PA and am getting just under stock. For me, battery life is first priority, even if there is occasional stutter. Testing battery life takes a long time, so I just wanted to see what others have been seeing. I would stay on stock, but I really want Tablet UI and real setting toggles.

Disable Google Now and see if that helps, totally did on my HOX and I've yet done it to my Nexus but I've not used it enough to actually deplete a battery yet.

You sort of want your cake and eat it too. If you want a ROM full of features and packed full of unicorn blood and the tears of leprechauns something is going to have to give and that will always be the battery life.
I use pa ...I charge my tablet every other day
Sent from my Nexus 10 using XDA Premium HD app
Stock ROM
Ktoonsez Kernel: Underclock to 1.3Ghz
Disabled: Google Now, GPS,
Freeze: all stock apps I don't use, Magazine, books, currents
Battery Life: 4 days.
I read a lot.
Don't game.
Watch videos with zero stutter.
I finally charged my tablet last night. Im at 82% in 8 hours.

I'm addicted to my tablet... I've been using it without stop for the last three hours. This are my results with Paranoidandroid:
Very similar with stock though. I think I could upload some as well.
I'm pretty sure this is stock. Not a lot of difference as I said. Both of the images are with very heavy usage, I mean, screen on all the time, but almost the lowest brightness. With the screen off I get almost no drop.
(I couldn't attach the image in the previous post)
Battery life will always be a combination of idle drain + screen on drain. THe most important is obviously how long you can actually use the tablet (screen on time), but you also need good enough idle drain to not lose hardly any charge between when you use your tablet.
The more features you add the less battery life usually is. So either keep PA so you have the tablet UI or use a ROM that is very close to stock, like the stock ROM from scrosler or Muzzy's ROM.
A kernel can also have greater effect on battery life. If you want the best battery then go with KTManta kernel. Use either PegasusQ or ktoonservative governor and add in some undervolting to lower power draw. Using this combination I was able to get over 13 hours of screen on time in 1 charge. Idle drain was about 1% every 8-9 hours.
Personally, I've found that my battery life has improved maybe 10% since running cyanogenmod. If I'm really lucky I can get 7 hours SOT. Not a huge improvement over stock, but its definitely better.
Its worth noting that I use the "performance" CPU governor, which is supposed to be a battery killer. Strangely it doesn't seem to make much difference for me though, it just makes everything quicker!

Well, it is difficult to notice a higher battery drop when it is already insane... XD. Well, according to battery widget I'm getting around 8h with the screen on, which is not bad.

I've used the "battery widget" for a very long time and that app is a battery drainer. Got way better battery life uninstalling that app.
