MYN's 2.2 rls 3

Anyone found out what kernel works best with it for battery life. The kernel it comes with isn't that great on battery life. Sorry if this was already posted.

Unfortunately, there are no definitives, and if you aren't getting good battery life with the stock kernel with warm2.2, you might want to start looking at some battery tweaks.
There is a thread over in the Evo 4g General forum, the title is "2.2 ultimate kernel review :: Updated 11/6/10" and the OP is skydeaner. His site also has one of the battery "fixes" if its not holding a charge correctly.
Unfortunately, I can't link to it, since I'm still a newbie poster, but, some of the higher rated ones are Kings #11, and the new Net 4.2 kernels.

Im having good luck so far with Nets 4.2.1 CFS more aggressive smartass universal.
There were a lot of people complaining about the awake time of the 4.2 build, so Net tried to tweak the 4.2.1 to have the great sleep time of 42 with the great awake time of 4.1.9
I havent had the phone awake alot today but with light use I have gone from 100% at 8 am to..... 75% at 10:30pm This was no browsing or games, just phone for about 5-10 minutes and maybe 5 minutes of texting only 1.25 hrs awake time total so far.... so very light use today. But ive NEVER had the phone stay 75-80% inot the evening.
I REALLY hope the awake performance is as good as the sleep performance. We'll see how it does tomorrow under some stress.

Just for a baseline, I just put my phone back to root to take it back, I've lost 50% over about 26 hours of moderate texting and usage with just JuiceDefender running.

I have Kings #11 and my battery blows. I drain 25% in less than an hour with moderate use. This is off topic but when you enable your 4G does it automatically turn off on you. I think my 4G is broken and just want to know. I may need to reflash it.

im runnin it with stock kernal and i have no complaints. I just took a screenshot showing like 43% left off charger for 14 hours and talk time was like 1hour and 23 mins. Plus iv used it to play mabey half hour of games and half dozen text. Il see if i can get the ss posted.

No it isn't unless you lose service completely I.e. a tunnel or if your battery goes too low

Calkulin's E4GT v2.0.1a VS Blazer Rom[12/11/11][v2.0]

They both claim to have great battery life and smooth operations. I am currently running Calk's 2.0. I get over 10hrs for my phone, depending on the usage. And the standby time is amazing. Now I am interested in Blazer 2.0 but I would like to get other peoples comments and opinions before I try it for myself. So, Blazer Rom[12/11/11][v2.0] VS Calkulin's E4GT v2.0.1a!!!! BEGIN!!! "ding ding".
Please and thanks to all.

Im running on phantomhacker's blazor rom and i get about 1% stand by time. With moderate usage (texting, light internet browsing, like 2 5 min phone calls) i got 1 day and 5 hrs. I could have gotten more but i couldnt afford my battery dieing so i had to charge it at 15%. With heavy usage of streaming music via pandora over wifi non stop, texting, and lots of xda i get about 14 hours with 3 hrs of screen on time. I havent taken screen shots but ill take some today at the end of the day.
Edit: mean 1% every 6 hours on standby

You'll have to wait until tomorrow. He snuck in the links when his wife wasn't looking; it's his daughters birthday today. I'm sure he'll update the OP and all once the candles are blown out and the cake eaten.

I've tried an older version of Calkulin's rom. Didn't like all the rows and stuff with the apps. It was too cluttered for me but much respect to Calkulin. I can't give anything but love and respect to developers. For me the Blazer Rom is faster and better battery life. The best battery life so far of any rom I've tried.
Lately I've been testing out this technique on calibrating the battery and it works well for me
http://forum.xda-developers.com/showthread.php?t=1312273

I tried 2.01. I like everything about the ROM, but it didn't work well on my phone. I experienced worse battery life than stock. With the phone stock, I was having no problems getting through a day on one charge. I think in the time I've had my phone (2 weeks after release) I had to charge it during the day maybe 2 times. Once I put Calkulin's ROM on, I never made it through a whole day, or even close. I suspect the performance tweaks may push the phone to greater battery usage. I was looking for better battery life, not worse.
I had lots of problems with hot boots. If I made a call, I'd get a hot boot after about a minute. If ambient temperature was really cold, I could maybe get 2 or 3 minutes. I got hot boots using various apps, and in some I got none. The phone became unuseable for me. I flashed back to stock.
I suspect that my cpu is not very tolerant of higher temps. YMMV.
I did like the ROM though. I like the 5 buttons on the launcher, the 25 apps in the trays rather than 16, and no CIQ.

Nexus CRAZY BATTERY？

I just flashed my GSM galaxy nexus to aokp build 22 and mated it with franco kernal 16.2. NOT using any extended battery.
im not sure if this is good or not. but 10 plus hours of battery and 3 and a half hours of screen time. near the end all the way to two percent i was tangoling with my girlfriend for an hour or so. CRAZY BATTERY LIFE ANYONE？
Sent from my Galaxy Nexus using xda premium

Yeah I am getting crazy good battery life too...Almost 22 hours off charger, 2 hours of screen time, and almost 50% of my battery remaining. This device is a beast, the battery is awesome.

Are you both using the same rom? Can this be the same with stock? My experience so far has been no where near that....unfortunately. Haha. Maybe I need to root and get this thing cranking!!!

No with stock I was getting much less.
I was running Gummy when that screen shot was taken. I have since moved to AOKP m3 but I don't find the battery as good so I am switching back to Gummy.

I consistently get atleast 15+ hours of battery with 4 hours of screen time on stock everything including battery. My brightness is around 25-30% percent though. I also keep my gps, bluetooth, auto sync off. Only use 2 widgets that refreshes automatically at a set time interval. Standby time is outstanding on this phone, it's just the screen that kills the battery. I can easily get through a week on standby.

Vacation Emergency

I'm in DC and need to make it through a full day on the battery. I need a from and kernel that can help me make it through a good 12 hours with no wifi and over 2 hours screen on time. Please help, I haven't made it more than 8 hours yet.
Sent from my Galaxy Nexus using XDA

Honestly if it is that important put a second battery in your pocket. Its the only guarantee.
With that said, I have gotten pretty good battery life on AOKP M4 ROM w/ Franco M2 kernel. I average about 20 hours, with 3 1/2 hours screen time.
Every phone is different though, so there can't be any guarantees. The only way to know for sure is to test for yourself. It doesn't seem like you have the time for that though. If it were me I would grab a second battery or a charging pack.

Try AOKP B29 stock kernel with on demand governor. I managed 4 hours of screen on time with roughly 20 percent left.

Just turn off LTE and background data/automatic sync. Your phone will run forever.

Yeah, i get those kind of battery statistics or better all the time with my GSM version. If you can just turn off 4G and it basically turns it into a GSM phone with a little bigger battery, I'd do that. Also, carry a spare battery if you are worried about it.
Enjoy DC too. Great place to visit. Lots to see/do. Tell Barack Chris says hi--he'll know who

You can find charging packs with over 5000 mAH for as low as $25 online. Since you're in a hurry, I'd get a pack from Fry's or similar places.

Go with AOKP Build 28 with Franco's Kernel. And undervolt your values a bit. Let me know if you want the uw values and aren't able to figure out yourself. Mine gives about 30 hours battery life with 3-4 hours screen on.

Battery pack or pick up some batteries.

WHO IS GETTING GOOD BATTERY LIFE ON ICS?? GIVE ROM and tweaks and hrs with use

I am serious about to go back to GB. ICS is sucking in the category of battery life. I need to know what is going on.
I am running Re-Calk 0.1.17 with Agat 4.3 and CPU Sleeper. Took my phone off the charger at 8pm and already down to 85% with it being in nothing but deep sleep. Same thing basically happened on Blazer also.
I need something to keep me on ICS. Someone please tell me what you are using.

I have had the same issue. Ive tried many combinations of roms, kernels and tweaks but I still haven't been able to match calk's 3.0. Curious to see if anyone is getting decent battery life on ICS.

I'm getting good battery on aokp m6 but it also varies widely depending on what I do. if I play alot of games or watch alot of video I have about 10% after a 16-18hr day if I just browse and txt I go to bed between 30-50%. Only tweaks I did was disable the capacitive buttons and led by deleting their files from inside the he folder in /system
We are legion, for we are many.
Sent from the DarkSide of the GalaXy with a MEK device

i use system tuner pro and change the cpu setting power save plus all add all the tweaks

I dunno, whats good for you? I am back on my trusty CM9 Nightly 7/17 which has the FF18 repack kernel which was supposed to be worse on battery life than the FF11. I get 30 hours or so on my days off or days at work when i might check the phone a couple times an hour.
Heavy usage any rom, any android version can kill an E4GT in 3 or 4 hours most days i get 6 to 8 with an hour of 100% brightness screen on time.

I am on the sprint official OTA and I avg around 13 -18 hrs with 5-6 hours screen time....could be more if I wasn't a heavy usage type

Wow, this almost seems too good to be true...What % usage was your Android OS? What other settings do you use (i.e. Auto Sync Off/On, Number of Apps, etc.) Are you sure you are not talking about the SG3?

2% screen on how many minutes was ur screen on

i think the reason why Calk 3.0 have superb battery life is because the CPU is underclocked at 800Mhz instead of 1.2Ghz

Just my $0.02
I was Super Galaxy ROM for a while and my battery life wasn't ever that great
I had to take my phone in for a signal problem (which ended up being a downed tower that the Sprint rep didn't bother to mention, don't get me started) and so I flashed to GB and then did the OTA update to ICS
I've been getting awesome battery life outta this thing now.. It was a really light use day today, but I'm at 60% after 13 hours (only 1 hr of screen on-time though).. but on SuperGalaxy I would usually be at about 20% of less even with little to no screen time.. (I did love everything else about Super Galaxy though)..
But I've seen lots of people say they got horrible battery life on the OTA... (I did start from a completely clean phone though if that matters)

no clue, i played a bit of temple run, made a few calls, and did a bit of texting

I'm running stock ICS and get the same battery life as GB. I can get 12-16 hours 8 if I'm on the phone constantly reading and browsing. Glad I don't have the issues others have had. At first my battery was pretty bad but it continued to improve over time.
