Post your battery stats and rom/kernel combination

played temple run and browsing.. made few calls as well.. is this good battery life??

That's pretty good.
My normal is AOKP M6 with Jame Bond 3.1.9.9 kernel.
Although I'm thinking I'm sticking to the AOKP JB nightlies now. Just using Jame Bond 3.4 kernel now.

That is actually pretty good. It also seems like you play games and that drains the battery pretty quick, especially since is using the GPU much more than in regular use.
I could have never ever achieve this kind of battery with my HTC Sensation even when running CM9.
Here is mine. Using stock but rooted JB and stock kernel.
Used for browsing a lot, Twitter, Facebook, Texting and YouTube videos.

Hi! I'll be going abroad in a couple of days and while I have tested most JB roms I'm not sure which rom has the best battery life. I'm currently using Rasbeanjelly and Trinity Stable 35 and I only got 3hrs of screen on yesterday (however I did have 3G enabled most of the time). Can anyone please suggest the best ROM for battery life ?
Thanks

They are all pretty much the same IMO. The screen sucks up juice so keep it off as often as possible lol

If you want the latest software, most stable, and best battery life ROM, go with MMuzzy's AOSP ROM. Using it now, and its amazing
Sent from my Galaxy Nexus using xda premium

ROMs themselves rarely ever have an actual impact on battery life. Most postive effects for battery come from the kernel, and negative ones from rogue apps.
Before you ask which kernel offers the best battery, it really depends on the requirements of the user and the phone itself. You'll just have to try a few.

Flash it like you would a ROM. Make sure you find one that is for the version of android your ROM is based on. I would suggest tying Franco kernel, but there are many good ones.

FYI....this thread goes in general.
Flash kernel in cwm the same as you would have a rom. Be sure to clear cache/dalvik first.

For the moment the ROM with the best battery life is SlimRoms 2.7

I've tried many ROMs and Kernels with no success in the battery life department.
My phone charger died so I downloaded an app...Easy Battery Saver...my phone was still at 34% after 1 day and 7 hours. I was NOT heavily using my phone but still this is the best battery life I have ever experienced. I was always on the "battery saver apps are useless" team until recently.
Don't get me wrong, I'm still flashing
Just love my new app.

i tried miui, pa, vicious, aopk, smooth, and now using cm10. tried out different kernals too,but at the end, all the roms cant pass 1hr 50mins of screen time.

Hmm.. thats strange. I'm on MMuzzy's ROM which is pure AOSP and I get around 2 and a half hours of screen time. And some people around the forums have gotten around 5 hours of screen time with different combinations of ROMS and Kernels.

I have tried numerous roms, if not all of them for the galaxy nexus, and there is a difference between roms, even using the same kernel.
I have been getting amazing battery life using Eclipse.

The mods can move this thread, but in the mean time, it is a good question.
I used to get some awesome battery life. VZW + 2100mah. Typically 4 hours screen on time was normal.... now I'm lucky to get 1hr. I can't remember if it was the jelly bean update or the inclusion of Google Now.

Does letting the ROM settle really help? I have been getting terrible battery life out of my 2100mah. The battery just drains when the screen is off. No rogue apps, but this is a fresh install as of 24 hours ago

I believe use what you like as long as you use Lean Kernel you should get good battery life.

I wasn't going to put my 2 cents in but because there are so many complaints about this being in the wrong place, I just have to now.
I have tried many different ROM's and kernels and found there always seems to be the "right" combination sooner or later. Right now I am on AOKP w/Franco M6 and getting about 14 hours with 24% battery left, 2.5 hours screen time, mostly LTE and moderate phone use, best I have seen of any combo for me on this ROM. For CNA the right kernel for me was lean kernel. A little experimentation and patience and you will find that sweet spot soon enough.
Edit: the whining drew me to it, sucked me in so I couldn't stop myself from answering

If someone can get 4+ hours screen with mostly 3G, let me know. haha.

Wrong section
However as for battery life slim ROMs work great but I'm on jbsourcery built in trinity and I've definitely had worse d: the only ROM I've used that's had has battery is pa however they've had multiple updates since then so I'm sure its not horrible now

4.1.2 improved battery life

After receiving the 4.1.2 OTA update, I'm getting a much better battery life.
It used to be dead at the end of the day. Now, I finish my day and the battrey is on 45% with the same phone use.
I also find that apps and mostly google apps do launch faster
Have you also noticed it?

CM10 "added" 4.1.2 into the compilation recently & I've noticed a difference too... :victory:

Can you give us some screenshots of the screen time?
Sent from my Galaxy Nexus using xda app-developers app

Only with data all the day i got 3.30h and 19h on, automatic brightness, sync on. Google stock 4.1.2

4.1.2 appears to have a big affect on battery life. I've gone from needing a charge after about 12 hours to going all day with charge left
Sent from my Galaxy Nexus using xda app-developers app

When 4.1.1 was released, people reported that Google Now was a battery hog. Maybe Google improved it drastically.
Those who experience better battery life with 4.1.2, do you have Google Now activated?

To add on to this. I'm noticing FAR fewer wakeups (alarms) caused by Maps services on 4.1.2. That has an impact regardless of whether or not Google Now is running.
They definitely made some changes to location based services considering the menus were modified and additional settings were added.

Using a custom ROM and kernel so I can't answer this. But my battery life using CM10 + Franco Kernel has definitely improved.

I logged in hoping someone had made a topic about this. On 4.1.1 I did not use Google Now because of the effect on battery life it caused. I tried it on 4.1.2 hoping it had improved. In my opinion it did. Still need more days to test but it seems way better now. Even saying that, I still feel it takes too much of a hit on battery for me to continue using it.
Just my 2 cents.

Umm, it absolutely wouldn't be better at all.
Rooting and using custom ROMs have it benefits and my battery life wouldn't be to where it is now (at least not as long) if i was on stock.
Stock is too boring for me. I need my lock screen customizations and backups

It doesn't take away root capabilities right?

The 4.1.2 custom ROMs have done me better overall than the 4.1.1 ROMs.

I haven't noticed much of any difference one way or another.

So the latest cm10 nightlies contain 4.1.2??
It seems the battery life claims are pretty circumstantial. I wish there was a standardized test for this..

Cm10 nightlies are cm10.
And battery is much much better.

I never let any Rom to settle down(for more than 2 days) to comment on battery life, but i hope the thread is pointing to facts
So now in Stock will report back after 2 charge cycles at least

The map process is eating my battery to. I reserve testet it yesterday (nandroid of 4.1.1 back) no problem and then again OTA to 4.1.2. Anyone out there a possible resolution ? Had 2-3 days with my battery, now maybe one day.

What ROM is outstanding with battery life?

I'm currently using cm10. Not really impressed with battery, but overall is decent. I'm looking for a ROM with pretty good battery life. Any suggestions?
Sent from my SAMSUNG-SGH-I747 using xda app-developers app

There is just way too many variables to answer that question. Just keep trying roms one after another. Also expect this thread to locked down soon!
Sent from my SGH-I747M using xda premium

Why would this be locked? He's asking for what ROM has good battery life, not which one is best or other flameworthy question.
Anyway, I think the Kernel has as much if not more importance with battery life. I use official AOKP JB Milestone (4.1, not 4.2) with LeanKernel and I get AMAZING battery life. I noticed that LeanKernel was the factor that did this for me, so you might want to give it a shot. I don't think LeanKernel works with 4.2 yet though.

The best way is to try them yourself. Everyone uses their device differently so performance and results vary across devices. Also ignore what the guy said, this was a good question.
Sent from my SGH-I747 using xda app-developers app

For me, best battery to date has been tasks aokp with ktoonsez kernel.
Their 4.2 rom is really nice but still in the early stages so I expect the battery life to get better but their 4.1 rom was outstanding with battery.

Just installed leankernal. Let's see how battery life will go. Thanks guys.

Check out AoCP. I've gotten the best battery life out of that ROM. I think I used lean kernel with AoCP 4.4. The current version is now 4.6.
I also use juice defender and cpu sleeper to aid with general battery life.

Does anyone know how the leankernel compares with the ktoonsez kernel for battery life? I was getting great battery life with kt and cm10

I'm basically looking for a rom that can last 8 hours screen time if that's even possible. Or close to that, data always on.

8 hours screen time with data always on? On stock battery? That's a tall order. Good luck with that.

battery life depends on too many things. my daily driver is awesome but if battery life was my main concern I'd never enjoy a ROM as much

8 hours screen time doesn't seem possible in my experience on stock battery. On Carbon ROM with LeanKernel I get a good 3-4 hours screen time when I'm gone for 14-16 hours from a charger.
Sent from my SGH-I747 using xda app-developers app

haha just my way of asking If 8 hours would be possible. I think the most I got to was 4 and a half. was reading reviews before I got the phone and it said that it has 7 hour screen time. Have you tried that extended battery? I was looking at some and was gonna buy one but afraid of buying a faulty one lol.

There is no such thing as best. My phone and your phone are not identical, even though they may have very been from the same production lot. Nor are the individual circumstances under which two given people use their phones identical. Something that performs extremely well on one phone may very well boot loop on another.
Do some research by reading the applicable dev forum, and then try some different combinations for yourself to see if they work for you under your unique set of circumstances.

KERNEL.

there is no best combo, there is only the best combo for you and your device. for me its rasbean jelly rom with trinity kernel. but whats best for me and my device might not be right for you and your device.

I've been using cataclysm with Franco kernel for a while and have been very satisfied.

Agreed, there is no best. I've had good luck with muzzy's aosp room and Trinity kernels. But you might not like that combo. I'm not interested in gaming for instance, so my needs might be different than yours. Try different combos and you'll discover your own best.

Ok.. got it.. thanks everyone

stock rom is the best in my opinion

I think Xylon (014) with the default lean kernel gives good battery life. Tried the ROM with Franco 358 but i went back to lean.
Also, i make site that my most of my apps aren't running in the background and using up the battery... That's what the FAQs from Franco's OP in his thread mentions.
Sent from my Galaxy Nexus using XDA

I get over 5 hours screen on time and a flawless smooth ROM with heavy usage with both data and WiFi on with xylon stable and ak purity kernel running Wheatley gov. I just addressed this on the xylon thread. Works well for me and some others.. Have a look its worth the flash to see.

Sent from my Galaxy Nexus using xda app-developers app

For me it's I've been on Muzzy's French Vanilla on stock kernal. However, I've read good things about tiny's kernal too but I haven't tried it myself.

As a noob in the android community, and after trying different roms, i like rasbean the most for different reasons, but on choosing a kernel, for example trinity, there are a lot of options. What's the difference? I really not get it :silly:
for example, TNP1536-512-JB-4.1.2-STABLE67
So this one is max 1536Mhz CPU and max 512 GPU i read on derkernel site
So there's a different setting for graphics (gpu)? I always tought CPU was working between 1536-512 Mhz?
And euh, when i have trinity's app, i can change the settings of this kernel to get this one? (TNP1344-384-JB-4.1.2-STABLE67)
So this is the same kernel but with different settings?
Please make me a little bit smarter
