Kernels & Battery

Hi All
I've done a bit of reading and see a number of different kernels about.
Can someone recommend the best kernel for extended battery life.
I currently get 18hrs out of my G1 running Froyo by Lazlo.
Yesterday I used navigation for a 30minute trip and my battery went from 100% to 15%
Surely this isn't right.
Any help / suggestions are really appreciated.

Farmatito's kernels are the best I've used. They resolve the battery drain issues and extend battery life.

Best Kernel?

What is in your opinion, the best kernel with performance and battery life?

WellI've had x99's kernels recommended to me several times whenever I've jumped back to froyo.

Currenting went from Tiamat to ScarySUV, Tiamat seems high in performance but ScarySUV saves a little bit more battery.

Stock CM7 kernel max CPU at 1.5GHZ, min CPU 200mhz, runs great.

Right now I'm loving Scary's kernels. His links in his post are dead though .

Have you noticed a difference in battery life? It's probably in my mind but I swear my battery life has been better since I pushed up the max to 1.5ghz from stock.

I'm still on sparksco's kernel, but I also did noticing a couple more hours out of battery life ocerclocked to 1.5
I found that strange but nice. Phone tends to overheat though so I keep it at 1.2
Imo, sparksco's kernel is the besy by far with performance and battery life.

Whats your range on life? I get about 17-18 hours on scarysuv with extreme heavy use.

yeah ill usually get about 20hrs. Moderate usage. That's with 3g off and wifi on.
Best I got was 34 hrs before.
ScarySUV doesn't really help my battery life. But I never wiped battery stats when trying that kernel. I might do that and see what I can get.
When I'm on sparkscos kernel with 3g on all day, the worst ill get is about 10 hrs with heavy usage.
Evo SHIFT

I get the same with sparks, scarysuv gives me decent about with amazingly heavy use but battery stats never done so I'm currently stay at 35% for about an hour and a half now.

Battery life is WAY better. Now if I could only fix my GPS. But yeah forgetting to charge my phone every night or all day at work doesn't feel like as big of a deal right now.

im running the warm synergy rom on my shift, is there any good kernels thatll run with that? id really like to get my shift oc'd and still use this rom. im used to using samsung garbage which is completely different from the shift.

Best rom for battery life and speed?

Wondering what the best rom for me to use would be?
I also feel like my phone uses too much battery searching for data.it burned 25% in 1 hour without use. Just because I didn't have a 3g signal

ROM has much less impact on battery life than the kernel. The best battery life you're going to get right now is on Froyo with an overclock kernel so that you can undervolt as low as your phone can handle.

I recommend updating your modems to the newest EP3HA leak. I have had much better data connectivity since. If you are in a building that is causing the issue it may or may not help.

how exactly do i do that?

nothing special put them in the PDA slot in Odin and flash it like a rom, then boot up your phone and you're good

Just wondering if when I flash the imo 3.1 for charge like you have in your comment (using humble 4.22) will it show 2.6.35.7-EP3 for the kernel in the "About Phone"? Just trying to verify if the flash worked.

I like it actually despite it being a beta however there's still issues one of which is with lagfix/ext4 conversion that soft bricks the phone so stock RFS for now (I should change the sig lol)... its fast enough and the cyan/ICS look is pretty cool, no accurate battery readings yet as I've had to flash it a few times the past few days to test stuff but it seems to be pretty decent
I also managed to grab a beta of Imnuts/TSM Infinity rom for EP3H that I used for a while and that was pretty awesome.. it was smooth, stable and had pretty good battery life, I don't know when they're gonna release as a final rom but it looked done pretty much.. there is an Infinity rom for EP1W though that's the same if you don't mind not having the latest leak lol

ahh, im still not really sure what lagfix/ext4 is.

voodoo lagfix is system file/partition conversion from RFS format to EXT4, makes the phone much faster and smoother

yes I believe it is.. as for the roms the devs will release test packages either on twitter or in the IRC webchat, they usually need people to try them out and report bugs

For battery life? isnt mdj's kernel overclocked? (GPU&CPU) Stock better i think.

Yes, it is overclocked but it can be lowered to 1.5 and has been tweaked to provide better battery life.

And its also known to corrupt internal storage

But GPU have to stay overclocked

I haven't experienced any corrupt internal storage issues with the kernel. I suppose that is part of the risk with flashing anything though.

You can always flash back to the stock kernel. I was also a little worried that OC'n everything would drain battery like crazy, but I easily get 1-2 days out of my phone. The biggest battery drain comes from the screen. If you're playing a game, browsing the internet, or anything else that requires the screen to be on while using the device... it doesn't matter if your processor is unclocked to 800Ghz, you'll only get a few hours (3-5) of battery life. There is no rom or kernel that is going to fix that.
If you think about it, overclocking the processor will allow you to do things faster and minimize the on-screen time.

Andromadus vs. Jellytime vs. PACman vs. Pure CM10

Hello,
at the moment i am using Jellytime. For now i am happy with this, but i think the battery life could be just better. So which rom from above offers you the best battery lifetime?

im using pacman.. the battery life is good.. i can use the phone the whole day(surfing, internet, texting, music...).. i always plug my phone in before going to bed, and i still have around 10% left

Using Pacman v18.0 at the moment and the battery life is not very good. Its usually dead by evening.

Me too. Battery life is very short using Pacman v18.0, at most 5 hours. The screen is the process that consumes more battery. Maybe it is only a my problem, but with Fallout v.5 I didn't have this problem (but others :laugh.

Well I find the battery life good on pure CM10.
If it wasnt for the graphics glitches when browsing, it'd be a really good ROM!

I have installed Pacman v18.0 about 3 days ago and am very impressed with the ROM. No problem with battery life but one major problem with the phone randomly going into Sim Lock mode. Could be after 5 minutes, could be after 5 hours and sometimes while just using it.

PACman, way to go.

I'm using Andromadus CM10.1 and battery is good...Overall is good except Bluetooth that doesn't work yet...

Mine has about an hours worth of battery...
For now I'm switching to my sense rom

On the latest build (build 10) of Andromadus 10.1 I found that the bluetooth was fixed!
Overall, at this time, I believe that the 3 andromadus ROMs are by far the best Jellybean effords!

Thank GOD I got here...
Could someone help me with rom that includes these features?
1. The official ics look (nexus ics)
2. That includes all apps like the sensed ics got. (fM radio,voice recorder,youtube etc)
3. My wifi doesnt turn on when i use any custom rom It just says "Turning on wifi" for the whole day.
4. The settings tab normal (not the tablet type like pacman got)
....
Thanks

why not try the ROMS yourself and find which one is suitable for u. Everyone has a different preference and taste.

I'am trying different roms all the time... right now I'm using FullySamsung-1.0.1 since couple of days... battery life sucks on this rom...
I do not see the connection between battery life and "preferences and taste"...
From my experiences all JB roms for DS are draining battery very fast...

some people prefer to UV their kernels. Some people don't prefer. Some kernels allow UV, some don't. see it all comes down to preference,of course UV also may cause performance to decrease. so it stills come down to preference.

That still isn't answer for a question from first topic... "So which rom from above offers you the best battery lifetime?".
It's just general deviation about the opportunities offered by kernels...

Hmm, when ppl say try it yourself, it simply means that u would have to flash the rom to know what's best for u.
Everyone uses his/her phone differently, so basicly there is no ideal rom that pleases everyone.
Everyone will you give a different opinion in terms of battery/speed/etc. That's why it is a bit pointless in asking what's the "best rom" for the other person when the usage is different.
So no point having second doubt and just flash the phone, try every single rom, i have flash from sense to cm to ics and now back to gb.
Go ahead and experiment the roms for yourself. Today someone might give u a suggestion, the next day a another. that's why it is consider pointless in asking such question as 'which is the best can u recommend me' and much better to try it for yourself instead of being shortchange in case there is another better than that is being suggested.

Does any one facing camera issue?
