Kernels & Battery - G1 Android Development

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.

I've been seeing a couple of posts that say that the battery life is noticeably better.
I love reading all this stuff about battery life.
Reality of it People is you probably just use your phone to much.
it's normal HIGH drain devices + small batteries = Wall Charger
If we want longer battery life we need higher .mah sure it would have been nice had it came with a 2200mah battery but you would be carrying a brick.
Found this... make wifi charge your phone.
http://www.ohgizmo.com/2010/01/09/ces2010-rca-airnergy-charger-harvests-electricity-from-wifi/
And the kicker is that they will still charge the phone atleast once a day regardless of a better "battery saving kernel" LOL
Uninstall everything from your device, it helps a lot. Or go buy Nokia 3210, you can use it 2 weeks without charge with stock kernel.

[Q] Stock ROM vs Custom ROM Battery life

Hi i'd like to know how battery compares on the DS.
I hear many ppl say that on custom ROMs the battery is better, but by what margin?
There is a person saying he had his DS approxiametly in standby for 200hrs (stock)
then with a custom ROM 400hrs...
is that an accurate prediction... do the custom ROMs increase battery by that large margin?
i would have thought that having all the newer sense 3.0 , overclocked ROMs etc, would make the phones battery life worse than stock, but it seems not so....
Anyone can share their expierences please?
i dont know about stand by but if u ask about usage stock rom battery life sux.I'm on cm7 (right now) and must say that this rom is the best one for battery life...tried miui,lbc,virtuous and now cm7 so far and in cm7 is no drain at all...7-9mA on idle ..all roms drain fast if u use wifi ..if u really use ur phone whatever u use stock or custom rom u will must charge every day thats for sure
in some lines, when screen off i get use of:
Stock: 14-15ma
Custom 6-8ma
Meaning that custom rom uses half of current... means better battery life
yeah just like that

on standby you can see a huge increase in battery life if you use a custom ROM
but when you are actually using the device the battery life isn't changed that much as the display causes most of the battery drain & so reduction in battery consumption of most other processes does not affect the battery life much,but it definitely is a lot better
& also most custom ROMs underclock the device when the device is sleeping so that also helps the battery life
AOSP roms had battery drain issues,but the devs are working on it & it should be fixed soon(im not sure if its fixed yet)
Thanks everyone for your input!
Will be considering rooting my phone and installing a custom ROM , once i'm fully settled in with it

would just agree with what @kartkk said above.
Would also say that you are correct to delay, as there are a decent number of guides and weeks worth of reading material here in the forum to keep you busy and help you along the way.plus lots of us here willing to answer any questions you may have as you should be fairly confident what you are up to before you start flashing.

yeah,i agree dont root your device for the first week or two till you can get all the info about rooting & also get to know the problems in stock so that you can choose the best custom ROM for you

with Virtuous Unity my device lasts two days instead of one day (with stock rom)
Compared with stock rom im getting around 8 hours more on the miui 1.7.29 rom by superkid. I can easily get over 2 days of moderate to heavy usage

Thanks for answers everyone! Recieved my phone yesterday.. really impressed with battery life on first charge out of box on stock! Can't imagine it could be even better on custom roms!

I haven't noticed a difference really, but then again I am over clocking now by about 400Mhz. Custom roms are just better all round.
Do custom roms without HTC sense last longer?

interesting question, since sense is quite often blamed for its exessive battery drain.

[Q] Roms & Batery Life

Hi, mitchel0 here, quick question,
Do different roms have different affects on battery life? If so, is there a place I can look to find what roms have the best battery life? Would major roms like CM10 have the best battery life? Sorry if these questions are redundant, I am running Codename android on my ATT HOX, and I am satisfied with everything this rom brings to the table, but the battery life, so if anyone can shed some light on this topic, it'd be greatly appreciated :fingers-crossed: thanks!
P.S, could flashing a different kernel help my battery life?

Sense will have better battery life in most cases
Have you tried using a battery optimizers app like juice defender or easy battery saver?
I'm running easy bat saver and I'm getting x1.8 extra battery. But I also keep my mobile network off unless I leave the house out of range of ny router.

There is no good answer to your question. For every ROM that people claim to have "best" battery life, you will also find people that have miserable battery on the same ROM. Just too many variables in how people use their phones.
Also, radio usually has more to do with battery life than ROM. If you are having battery issues, try a different radio.
Thanks guys. One more question now, will different radios affect my coverage? Like will I get better service with one but worse with another?

Possibly. Or you may see no difference at all.
Battery drain may be due to poor reception, if the phone is constantly trying to connect to the network. The right radio can sometimes fix both the reception and the battery drain.
But don't expect a miracle. Differences can sometimes be subtle, if even noticeable.

[Q] Best ics battery life rom/kernel?.

Hi, ive been searching trough isc roms and kernels trying to find one with a good battery life, but there isnt, they all talk about customizations, power, performance but not about battery life. I flashed CM9 with its own kernel and its nice, but it got crashed some times when i was websurffing and the battery life gets like 13hrs of standby and 3 hrs of usage (wifi, network, display), so i went back to GB stock. im not sure if its an isc problem or just becuase of CM. Well id like to know if there´s an ICS rom or kernel that gives me atleast 24hrs of standby and a good stability.
And what about the CM9 crashes?, its isc´s bugs?
Im wating for a JB release, as it seems to be bettter than ICS. Thanks for reading , and sorry for this questions, is just that xda is the best place to find information as im a newbie in android c:
try the hefe kernal or one of the newer ones posted by team Fahq. Might help with stability.
Then flash the battery mod posted by itzik2sh. That made a very noticeable difference for me.
http://forum.xda-developers.com/showthread.php?t=1985073
I was running ultragen with hefe kernel+itzik2sh's battery mod and was getting very very good battery life and the phone was stable.
Also changing the governor to SmartAssV2 can result in great battery life, even if my phone is clocked to 1.2 or 1.4 GHz.
But if you do not understand overclocking, do not try it, I read a couple articles before I actually OC'ed my phone.
If you want performance and battery life pertaining to kernel, you can try Hefe or Lightning Zap.
Other than that, you can try tweaks around OUR forums and see the results. You can also install Pimp My Rom to install tweaks.

, dont worry about overclock, i know all the risks and even CM9 from team acid gives you that option. But just let me know man, what is a governor?, never heard about that, and how much time you got of battery with that?

This thing called google brought me to a link to explain governors, so I thought I was paste it for you, even though in the time to type in your question you could googled it yourself.
http://forum.xda-developers.com/showthread.php?t=2005306
As to say how much battery life? Doing what? On standby? With the screen on full brightness playing GTA? Connected to data all the time?
There is no answer to that, because everyone uses the phone differently. Obviously if I say I get 2 days out of my phone and someone else gets 2 hours, maybe I only sent 15 txt messages and they watched HD Youtube off data for 2 hours while their GPS was on.
Wifi and GPS use a lot of battery when always leave on. Turn it off when u don't need it. Hefe kernel seems to help with the battery drainage issue.

Dont get mad man. About the search, ive done that, but here i can find a better and smaller answer. And about the battery,as you suere read in my first post upside i was saying in standby and a light use, and how much it lasted for me (a very short timefor a new battery). Anyways, thanks for the link .
And thanks mike y, Ill try out your combination.
I'm currently on UltraGen with Hefe-KOD kernel. Great battery life with good performance. Attached screen shots is with lite usage. Came from AOKP Milestone 6 latest build. Great battery life as well. Will probably go back to AOKP in a few days.

That battery life is because he doesn't use his phone.
Ive noticed of that, but even when I was on CM9 i got only 15 hrs on standby, either way, what thing really provides that battery life?, Ultragen or Hefe kernel?

Battery life is a very subjective matter.
Everyone uses their phones differently,so , judging battery life between people is hard.
Yes , some ROMS are better than others.
Yes, some kernels are better than others.
It is the combination of the right ROM and kernel for you that is going to matter.
And no one can tell you what that is.
Experiment for a couple of days to see how they work.

I installed ViperS 3.1.2 (which is now available as 3.1.4) and have found that to be excellent. On stock ROM with stock battery i couldn't last a day, now have an Anker 1900 mAh with ViperS and I get 2 days worth out of it.
Hope that helps
Two roms
Sense 5 and Revelation 1.0.3 Has Great battery life in my case
