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?

Battery Life on Neophyte's Rom

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..

[Q] Which custom rom has the lowest battery drain?

Hello
Thread title says everything. Want to know whether a sense based or an asop rom has the lower battery drain. Maybe somebody who has already had both types of roms on his DHD could post here some informations.
Thanks in advance.

Usually an asop one uses less battery but its easy enough to have a sence based ROM and flash an undervolted and overclocked kernel to save battery.
Yeah but uv/ov kernels are still not available for 1.72 based roms.

They are all the same mate.
Display takes proportionally the most out of your battery, no ROM can quite compensate for this.

What is the best virtuous kernel for battery life?

I downloded and installed the latest version of virtuous sense and saw in rom manager there was 4 different kernels. Cyanogen, virtuous, evil, and htc stock and was wondering which kernal peoplee think is best at the momment and why? Thanks for the help
Sent from HTC Desire Z using XDA App
1.02 was solid as hell. I'm using 1.05 but have a few new programs running in the background and the battery life isn't as solid. Feels a bit snappier but it's hard to tell because I made a few changes. I'd probably suggest going with the latest kernel though.
Anyone else have any advice on best kernal thus far?
Sent from HTC Desire Z using XDA App
My opinion, when I was running Virtuous which wasnt but 2 weeks ago, was eViL kerenel 12-10-1 which is on rom manager.
if you check out the thread for it, rmk and evil post seperate kernels that arent found in rom manager. im running 1.05 right now and its pretty stable. just to be safe, use the default. on average for any kernel mostly with set cpu profiles, i get about 7-11 hours of battery life. (witth heavy texting, web browsing and light calls)

Best battery saver ROMs

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)

I find the Kernel makes all the difference. Droidzones battery saver or gingercakes.

Unfortunately, MIUI roms does not have Sense.
Sebs runnymede aio v6.1 with droidzone #18 kernel, very fast and I am currently 26 hours with 30% battery left, moderate use, all simple battery saving tips used.
Sent from my HTC Desire using XDA
If I had to choose one that has the better chance of having a
better battery life, it would be the IncROM.What do you think??
Not the rom depends on battery life, it's nearly everything about the kernel (although I think Sense is also a battery drainer).
So if uses a good kernel (cannot recomend one because I do not like Sense) and one will have very good battery life.

ive recently tried using runny 5.1 (yes... purely for the swipe notification removal) and it trounces any of the other sense roms ive used, though tbh i work at a desk all day and i walk home and im not too far from a socket so power hasnt really been much of an issue.
NICE
i have some questions

Yeah, and how about to ask these questions
I experienced the best batery live with runnyrom but The Aio rom is with #18 kernel is also not bad
Other than kernel I believe that choose app also quite important. For me currently using runnymade ROM and the batteries is stay quite longer and it become drain fast after I install "LED me know" app.

I would recommend RSK v7.1.... The fastest nd most smooth sense 3.5 Rom I vet used... Good battery life.... No lag whatsoever....
Tried sebs AIO nd RunnyRom.... But RSK is the best....
There have been some new Sense roms released in last 10 months, including some Sense 4.1 roms.
What is the answer to the question form the original post today?
I changed from An - droid after a year with it to Alex-V, which is a hybrid rom. Same number of apps, same number of services, at this point the rom is still fresh, but is much faster than previous which was made for Desire. I can't make judgment before a month or so using it, but I was surprised with this revelation. Battery life is _much_ worse tho so I'd say general rule of the thumb is that Sense version and battery life are reverse proportionate.

What is that hybrid? What I'm really after is this Sense lockscreen which displays unread messages, calls, and agenda events from calendar. I tried Runnymede 3.5 and RSK 4.1 but none of them had it. I only saw it on ICS Sense 4.1 ViperS for Desire S.
Hybrid = sense 2.1+3.0.
Sense 4.1 is much closer to being an unusable pile of binary data than being a rom.

I also think that the kernel does greatly for the life of the battery, the frequency (minimum and maximum)... i use isl-r4mod-kernel-bravo. This kernel use in many roms.
A rom with sense him does not last very much the battery I advise to use the roms of mildwild ... normally I use Mildwild mw-6 based of Redux. With this rom the life of battery is approximately 2 days. : Good:
