ROM & Kernel with the best battery life?

Hi, so far the only rom I have used is CM6, and the battery life is just absolutely terrible. Maybe its just my nexus, maybe not, point is I want a new ROM.
A ROM that you guys have tried and decided to stick to.
Battery life is VERY important to me.

Try IntersectRaven's CFS kernel, best I have found for CM
For ROM try Enomther, battery life pretty good on that one

I had been using CM 6 for a while and just recently switched over to Enomether's latest TheOfficial ROM. The battery life is now DRAMATICALLY better. Just looking over the Juice Plotter graphs shows that the standby time overnight is almost flat. Say 3-4% drop every 3 hours or so. With CM6, the battery level is on a constant and steeper decline, even when not in use. I didn't take any records, but my N1 on CM6 would be down to ~45-50% overnight if I forget to plug in the charger (from full). I heard that SetCpu will help, but I don't think it worked out for me.
Enomether has its own CPU Governor and while it doesn't offer as many features as SetCPU - the ROM's default settings work well right out of the box - no tweaking is needed really for the CPU governor.

I too was having really poor battery life with CM6, losing about 50% within 8 hours after charge, without even using the phone much! I'm trying out other roms right now just for fun. I'm using Evil's Nxsense but with the kernal posted by Autinhyeu (post # 8541 in that thread). So far seems to be holding battery extremely well. About 5 hours since charge and about 90% battery.

LeoFroYo Rom is pretty good with battery

try the leofroyo rom latest beta. i get great battery in standby with the stock kernal that it comes with. 2.5 hrs per 1% battery. typically in a day making calls and using the internet, i lose about 30%-25% battery. not too bad.

cm sucks when it comes to battery life in my experience. i tried the 6.0 version when it came out (first stable release) and battery life was horrible.
5 hours since charge? only standby or some usage?

That was mostly standby with setcpu profile setting cpu to minimum when the screen was off. But even with those same settings on CM6 my battery would be about 70% after the same amount of time.
I just reflashed cm6 but with that other kernal so I'll see how well it works today.

MIUI has the best battery life of any ROM I've used on my N1.. idle drain of about .5% / hour when using pershoot's kernels from droidbasement.

I'm using shadow rom2.1 stripped down and I get about 16 to 18 hours usage.

I'm using CM6 and my battery life is great. I got rid of my Seidio extended battery to get an Otterbox case and the stock battery on CM6 is awesome.
My phone has been off the charger since before 1pm and now at midnight its on 46% and thats with heavy use of Angry Birds, text, emails and web browsing !

My battery life is also acceptable on cm6. Not amazing but acceptable. Then again I put mine in airplane mode overnight and get about a 4% drain, which I kind assume might be something to do with my Widgets.

Okay, so I decided to try one of these two ROMs:
Enomther
LeoFroYo
not sure which one yet, and not sure what kernel to use with the ROM I choose.
I hate switching ROMs cuz of the wiping and restoring and all that crap.

do you guys know if the leofroyo rom will work with slcd nexus w/ updated HBOOT??
i posted in the leofroyo rom thread, but no replies yet. itching to give it a shot.

[Q]Best Battery ROM

Hi guys!
My gf just got a HTC Magic but i don't know much about this phone so i would like you to give me a few tips. I have a N1 so i'm not a totally newbie to android and the ROMs thing.
I've installed CM6.1 into hers phone. Also i've installed and configured Pershoot kernel with setCPU:
Install SetCPU 2.x (by coolbho)
Autodetect, Min: 122, Max: 576, onboot, ondemand
Do not enable or setup Advanced
Click to expand...
Click to collapse
but i'm not liking the battery life of the phone right now. I let it during the night with 64% battery life and in the morning (8h later) it was at 60%. It looked great for me. The problem is that like for each 5min using it 1% of battery drops. It is just not normal! Is it the kernel? Or CM6.1 or...?
So, my real question is: Is there a "combo" of ROM-kernel-radio-cpu-whatEverElse to get a great battery life? Should i stay with CM6.1 or change to a another (based or not in CM6.1)?
Thank you all

Make a new profile in SetCPU for when the phone's display is off. I use 176mhz max 122mhz min, and 590MHz min/max (performance profile) during the day.
I normally use my phone for ~an hour a day during school and maybe another hour when I'm at home, battery is always around 50% by the end of the day. Which I consider to be fine, I can use it two days without charge but that's a bit of a stretch.
Anywho, radio and SPL combos aren't an issue, forget about them. ROM & kernel is what's important. I don't flash ROMs very often but I'd highly recommend t-mobile's Froyo build, it doesn't contain any bloat, unlike CM and becuse of that seems to perform even better.

I have ran cm 6.1 rc1 and the battery life is not the greatest. In my opinion cm6.0 stable has better battery life.

I have been in cyanogenmod foruns and i found that more people arent totally happy with cm6.1. Looks like that the last kernel (35.x) has some problems. There i read that the kernel 34.x doesnt have this problem. Im testing that kernel now.
Sent from my HTC Magic using XDA App

ok guys!
i think i found a way to get cyanogenmod 6.1 working with "good battery"
i only installed ezterry kernel (that i found in this post) and now i get much better battery life.
i believe i will get a steady 3days with with some wifi usage

Which ROM and Kernel for better battery life?

I'm looking for a ROM which can make my device hit at least 24 hours with light/moderate use. I know it's based on how the much the user interacts with the phone, signal strength, etc but there has to be a ROM which made your battery life amazing! I'm currently hitting about 12-14 hours with light to moderate use. I've seen people that use it the same amount and get nearly 2 days, how can I achieve this? I read somewhere that Pershoots kernel does well with extending battery life.
I'm currently on CM7 with the stock cm kernel.
Thanks for any helpful posts!

Okay so in my experience to get 'good" battery life with a g2 you need to turn off your push updates, stay off of data as much as possible, and only hook into wifi when you need it. Make sure your screen is on for no longer than 30 seconds, turn down your brightness, and set some profiles under setcpu to downclock you after you get to sub X battery life. Just make sure to increase the priority the lower your battery life goes.
The best and most consistent battery life figure I've gotten is 42-48 hr by generally not being a complete dickwad. If you flash a rom and have to download all your apps again it is going to suck you dry. I ran Cm6.1.1 with preshoots kernel for a goodly while and have pulled the same speed/battery life as I do on Virtuous with Advanced Kernel. It's taken a couple days for it to settle in but yeah, you're looking at 42ish with moderate net usage, full signal, and darn near constant texting.
Edit: Let me clarify. As your power goes down you should downclock in 5% increments. For every 5% less battery power you have, you need to increase the priority of that profile by 5%. Make a profile that is 100% priority but downclocks your cpu to 350ish max and 200ish min. Also something to keep in mind is that every piece of hardware is different. Some people can report fantastic life on the same kernel and OS. Just one of those weird machine god things.

I can get a day and a half with team villian sense ginger. The one before 3.0 best battery life i have seen yet. This is a 1.5days with constant OC no screen profiles or any kind of battery saving profiles. I would say im a slighty less then heavy user. Wifi always runs and i use gps for about an hour depending where im going. Now i normally charge her up every night but i have forgotten on ocasion and made it till i got home from work the next day.

+1 on villan rom, i set an off screen OC to 300MHZ and an on screen to 1.5Ghz, and i get 20+ hours out of it with mild data. wifi off unless im home and location always turned off unless i need it.

Might give that villian rom a try, is there a specific kernel I should use? Or should I just use the one that's already on the villian rom?
Sent from my HTC Vision using XDA App

just download from the current thread, the 1.5 version, it has an kernel that OC's to 1.5GHZ and works well.
i would download as is, and if you like, play with the kernel later on if you really want to.

Or if you like sense get sense ginger. Im not sure how you can get the older version but you could try the new one.

He is right, but lots of us has been through several ROMs and I can say that from the look of it all the ROMs use lots of battery life due to all the running processes. If you end up finding a ROM that supports your needs post it and let everyone know. Hope I helped

DHD battery life

can someone help me with the battery life on my htc desire hd i want better battery life without dissabling features, thaanks in advance

Well, there are many factors to getting good battery life.
Matching Radio/RIL can be a good start, especially if rooted.
Definitely ROM's also have a big part.
Overall usage will also bare a pretty big footprint.
I get about 18 hours on a typical work day, with moderate usage which is generally enough for going to work, coming home, and then still have plenty of battery left when I'm ready to go to bed, which is obviously when I charge my phone.

Define "disable" and "features".

disable automatic synchronization and shine

+1 there's nothing wrong with setting your Facebook, Twitter, Email, background syncing, weather etc to less frequent but it will obviously give you more battery life than syncing every 5 minutes, common sense really. An app to preserve battery I have found is Apndroid. Have the widget on your home and you can use 3G when you need it rather than not.

I disable automatic sync of all apps. I only update manually when I use them.

if you can echo all the timings I've been disabled, the sync I maualmente when I access the email application, facebook, etc. .. tweteer

have you rooted your phone? which rom are you using? some details will be appreciated...

tried custom roms? i usually get better battery life with them,
also setting off auto brightness helps a lot for me.

Green power free,its amazing my battery lasts at least 60% longer with this app,amazing get it

hey, mate... you've got some very generic question... specific info like ROM you're using, Radio, Kernel would bring justice for members to give you some more specific help.
This probably might help:
ROM CoreDroid 7
Radio 12.54.60.25_26.09.04.11_M2 - (HTC Ace Gingerbread S Generic 2.36.0)
RIL_12.54.60.25_26.09.04.11_M2
Kernel LeeDrOiD GB V3.1.6 - 2.6.35.13 BFS KERNEL (thanks to LeeDroid)
Live wallpaper Nexus Revamp
disabled wifi, refresh, gps (used powercontrol widget for accesibility).
After flashing, my battery was drained in 5 hours even after an overnight full charge.

(thanks to marosige)
Cyanideskittle2010 tips will prove really helpful. tweak around phone settings which are my priorities... things i don't normally use disabled them, enabled them when i need to.
also, installed cpu clocking, initially used setcpu, then moved up to cputuner which gave me more options... juicedefender also can help if you prefer it. setcpu or cputuner are both available in market.
gave my phone 24 - 48 hours, after battery calibration, full batterystats wipe, now i am good at 30 hours battery time.
used to have 36 hours battlife but was using CoreDroid 6.7 then... shifted to CoreDroid 7 because i just love its UI.
hope this helps! credits to all xda cooks & chefs, sergio76, coredroid team etc..

the new honeysense 6.0 rom has a extremly good battery life. i wiped the battery stats and now my battery lasts abaout 2 days instead of one

Don't want to steal your post but i just have a question haha.
I ordered a battery off eBay the new battery runs on 1600mAh while the original battery goes on 1230 mAh. Should i worry about battery stats i should wipe after replacing the battery or something like that ?

I think it's better to wipe when the phone is fully charged (test with currentwidget) but i think to best is to use the original battery. It can damage your phone and I often read that those batterys don't have more power than the original.

Is it normal that from full battery after night I have only 50%? Extremely strange for me... I have ARHD 5.1.10, ANDIDA 1800 mAh

i am using ARHD, it has good battery life. Works for me

[Q] Battery life very bad on CM7

Hi everyone,
I have a big problem of battey usage on Android...
I flashed the NexusHD2 rom in a first time and i realised the battery life was very bad ! (I lost 3% for 5 minute of use !)
I flashed the famous Typhoon CM7 rom and it's the same...
My Radio is 2.15.50.14 and i use CLK.
Thanks for your help

Try a different kernel. That helped in ICS, so after some trial-error you should find a good one.

What kernel is the best for it ?

I use Hyperdroid w/ seader r9 kernel. I get pretty decent battery life with it. But you also have to remember that the HD2 is a bit older so it has a smaller battery and less power-efficient parts.

Agreed, i flashed STOCK Windows Mobile 6.5 from T-Mobile and the battery lasted exactly the same time as with Android on it. I found that the ROM/Kernel combinations only matter a little. The phone alone has horrible battery capacity.

A bit?! Lol that would obviously help a lot. I'm not quite sure how accurate CurrentWidget is, but in terms of standby battery drain I get 5ma drain with wifi on on my phone. On the same settings on my Mum's Desire S she gets 26ma. However she gets great battery life, which I would only guess is due to the larger battery (and the fact that she barely knows how to use the phone, so the screen isn't on very much at all).

I use batterymonitorwidget pro. And i get around 5ma with wifi and cellular on.

Try using an app called JuiceDefender - it works really well at extending battery life. It basically lets you tweak loads of options to do with data and syncing, so you can have it set that data doesnt run when certain apps are open, or data is off when the screen is off, etc.
There's an ultimate version available, but it is £4.99 from the play store. But I guess that'd be cheaper than a new battery?

The same problem occured to me a few weeks ago. I have been using HyperDroid-CM7 which worked quite decent for 5 or 6 months and had very good battery life. ABut a few weeks ago suddenly the battery life became to awfuly decay, wasting 20% of the energy for idle hour instead of the normal 1-2. I changed the rom to the NexusHD2 ICS port and the battery life slightly improved but rhe problem stays the same. Could it be because the battery itself is broken or some software calibrations are needed (I haben't done any for an year since I bought the device)
