Hi
What is A Kernal ? Why i need it ?
thanks
A kernel is a layer of software, responsible for communication between the hardware and the OS. It is also responsible for power, cpu and memory management. Diffrent kernels can vastly improve battery life and device performance

Can Flash KERNEL on the stock ROM? (I have Eng S-OFF and Rooted)
Yes you can

Definitely worthwhile doing. Will help your speed and battery life no end

Pretty much already said and answered, your kernel is your best friend, it's all about finding the best one for you, basically, it will determine your handsets speed, battery life and overall level of awesome . I reccomend LeeDroids or Buzz's. Their kernels are pretty stellar, and almost always used in many custom ROM's.

Which one has better life?
Sent from my HTC Desire using XDA App
neophytes rom compared to what ?, its definitely better than the default rom. I found that neophytes rom gave me excellent battery life =D
compared to NexTSense? i think NexTSense have good battery life. Never tried the Neophyte's Neophyte yet.
Oh sorry heh heh. I was in a rush a wasn't very specific. I meant between his two rom's. Anyone feel any difference between his stock based one and his sense based one?

I switched from the normal one to the battery save, and noticed a distinct improvement in battery life.
That said, there are so many contradictory comments on threads about overall performance of different ROMs, the only way to find out is to give it a go on your phone.
I guess it is fair to say that the battery save version should be better, but you may not need it....
Battery save Roms only run up to 800mhz though
Having tried both I feel that Neophyte 1.6 is the best Rom for battery.
Alright thanks everyone. I'll give then both a try.

i run my NexTSense on 806mHz only..
Hi what kernels best for battery? Any suggestions welcome!

Usually the one that comes packed with a ROM, so really depends what you are using tbh. If using CM7 then use the one that comes packed with that one, if using on of the Sense ROMS, ARHD or LeeDroid, I would recommend one of theirs. IMHO for the LeeDroid you shuold try and use the one with the BFS as it seemed to give better performance and when coupled with the Smartass Governator gave really god Battery life.
There is also a guide to enlarging your battery life on here somewhere. I will post it when i find it.

There ya go
i'm using Coredroid 8.1... and Lordmod's v2.1 cfs kernel...
very good battery life plus quick usb charger... it charge faster than the power supply one
Currently I have ADHD but it does drain pretty quick,I'm careful with WiFi etc and running services but still goes pretty quick,are various kernels compatible or are some specific?

Can anywone tell me a best rom for save battery ?
Now i have Oxygen 2.3.1 Bravo
I would think the Oxygen you're using would be one of the better one's for battery life. Don't go for Sense rom's as they'll drain your battery real quick.
Well anything oxygen based, or the gingervillan roms
Took me a week to finally get it right, but I've managed to get both speed, stability n a Schweeet batterylife
If I get the time this weekend, ill post how I did it, and all the steps from stock, out of the box, to end product

I find that the insert coin rom isn't too bad on battery life. Well version 1.1.1 isn't. not sure on the newer versions though
Most AOSP ROMS have great battery life. But much of the battery life is to do with the kernel too, so picking a good kernel is paramount.
I'd agree on the kernel bit, but also, how you have android configured in general around it can have a noticeable effect.
The right rom, kernel, and also userspace setup/configuration all adds up

Also black background for AMOLED screens is worth adding to the list.
Im curious guys on this battery subject?
I'm currently using aurora V3 but even before that I'm lucky to get a day out of it.
What potential increases am I looking at here?
Many thanks

There is no way to guess or add a multiplier from your rom ro another to see potential increase unfortunately. It all depends how you use the phone. If the screen is on all the time, you wont see any increase in battery life as ROMs and kernels cannot control the amount of battery a Screen uses. This is a constant.
ROMs and kernels optimise CPU so that les spower is used, therefore things that use CPU will affectively waste less power.
The only way to test / compare is to flash something else and use it the same as you do every day.

Thanks for the info; need to do abit of research into this kernel business as I've seen them mentioned alot and nodded in agreement (I have no idea!)
Click the link to guides in my signature. Read the kernel info thread. May help

I don't mind if anyone throws me a pm in regards to seeking more out of the Desire.
And rootSU, we could always do a combined guide on the Desire and how to get the best out of it, if you like

You could assume stock, then at the bottom add root only and mention kernels and set CPU, autokiller, autostarts etc etc
Rightyo, need to do shopping but will be back shortly
Might see what i can work out
AOSP roms are the best for battery of course, but if you like SenseUi, I recommend You InsertCoin 1.1.4 and kernel from -SNQ, (his kernels are better for battery from bananacakes)
Hi everyone,
First time flashing cm 7.1 stable. Pretty satisfied with the beast...but the battery life has decreased from 30h to 18-20h.
Do you recommend the latest hboot? Wich kernel? Wich radio?
What are your battery stats? Do you recommend nightly?
Thx peeps

Latest radio. As for kernel a lot of people suggests ManU. I personally use richardtrip's kernel right now.

How is your battery life doing? What about your signals strength.
Thx for sharing

I've been satisfied with my battery life. Its pretty much dependent on how you use your device so giving you an actual figure on how long it last isn't really necessary. But on my observation, its better to flash another kernel than use the one loaded with CM7.
In addition to the kernel, I use 2G and turn off data when I don't need to be connected and all that normal battery saving practices.
As for signal strength I'd say it's pretty good. I never worry about it since there is pretty much good coverage where I am at.
I'd recommend you don't mess with your radio unless you have to.
I'm using cm7.1 with latest radio (5.17.05.23) and the ManU havs-axi-cfs kernel.. It works a treat for me

What are the consequences of flashing a new kernel over the CM one?
Data lost? Any apps non-compatible? Less customization of the cm 7.1 ?

There is a little trick how can you extend life of battery to the maximum: Use your phone only in pitch black rooms. Satisfaction guaranteed!

None of that. Everything should work fine, maybe faster, maybe slower, may more battery life, maybe less... Just try.
Only make sure you are flashing an AOSP kernel and not a Sense kernel.
The hboot doesn't affect the baterry life. A2SD dos affect, as reading and writing in the sd drain a bit more battery than just in nand.
So the best hing is to use CM7r2 and not to use a2sd, and don't have thousand of stupid and useless apps.
Currently on LeeDroid 5.1.1 radio 26.14 stock kernel...
what are the best rom/kernel combinations for gaming, then again the dhd doesn't have much battery life.
Does Lordmods CFS kernel add battery life and help extend life for dhd gaming?
thanks
Everyone will give u different opinions on this, best thing is to try them to see what works best for you. What works good for me may not for you.
