I've seen in the last months a lot of new roms and I can't try each one of them. So someone can help me to decide what is the best rom for battery life at the moment?
Now I've a defy with the stock froyo rom.
Thanks
i would suggest you http://forum.xda-developers.com/showthread.php?t=1285007 or walters msginger.both have good battery life
for performance cm7,miui,cmiui and the list can go
your choice
You will find that the stock froyo will nearly always have the better battery life than custom roms.

wajkIUI is good
well ive been on miui then on wajkiui all have a good battery life with a moderate usage i can go for minimum a day and half
and when not using is it goes on for 3 or 4 days
Best battery in sleep mode
It depends mainly on 2G and 3G network or Automatically.
Only 2G saves lot of battery
Only 3G drains lot of battery
Automatic is in between. But it trys to hook towards 3G before it hooks to 2G.
Hence in any ROM... if you select only 2G, it will save lot of battery.
2G with manual network selection will still have a better battery.
Yeah barebones had the best battery for me but its not been updated for a bit now then Ms2g 2.1 (I personally love it ) but as mentioned above remember to change to 2G when you don't need internet.

I think the most batterylife gain you will get from undervolting for all ROMS. My settings are [email protected], [email protected], [email protected] stable as rock on WajkIUI 2.2.3
CM9 ICS Epsylon latest version.....endless battery
undervolting.... sometimes is a problem... if network signals are low ... the network radios need more battery voltage... if it cannot get more power... the defy hangs and has a FC.
Same with other apps which need a sudden power.
Main drain comes from 3g and constant connection to internet. Loose those two and you get 7 days at least.

cpu undervolt doesnt have anything to do with radios or anything else. It just affects cpu and maybe Bus speed.
The best battery savings come from turning off the radios, 2g only, automatticaly turn of wifi during data off-peak hours (if configured), screen brightness, and finnaly cpu undervolt. A full review of all of this is in my old post with the name "7 days of battery".
Hi, my Triumph should be arriving in the mail in just a few days and i was wondering which is the best kernel or ROM and Kernel combination that is best for battery life? I've heard that battery life on the Triumph is not so good. Maybe it's false but i would still like to know.

I would go with CM7
That's what i was planning on. Does your Triumph give you battery problems?

The battery life is a lot better now with the latest builds of CM7 and MIUI.
I just use CM7 and leave wifi and bluetooth off, no juice defender or anything like that and I can easily go all day with no charge, typically about a day and a half and my battery is getting low but it really depends on what you are doing like games, wifi, videos and whatnot.
Before I think there was a problem with the battery draining while in idle but things have cleared up since then, There are also third party kernels you can OC and everything, but you can use them to undervolt as well to save some battery if you know what you are doing. over on androidforums there is a lot more chatter about this phone, just so you know.

Thanks. I got my phone today and im loving it so far. Do you know which of those third party kernels are good for battery life and that i can install over stock? I'm not quite ready to install a ROM yet but i already did the HTC Thunderbolt Build.prop tweak and obviously im rooted.
It's usually not the kernel but whatever governor you have it set to use. Even the stock can get improved performance if you switch the governor to such--”performance”--but I'm probably not the guy to tell you about which one is best.
I also have the silly feeling a lot of misconceptions abound here...in the form of ”I changed this setting and now my device lasts longer..., oh btw I no longer play with it 24/7.” In other words, use drastically impacts battery performance. JuiceDefender is an amazing tool but it won't do you a bit of good if you're testing out your phone's Adobe Flash capabilities regularly.

The Savagezen and interactive (not sure if interactive is on any of the kernels for this phone.) gov isn't that great. At least not in my experience. I had SmartassV2 on my girlfriends phone and it got ~3600 on Antutu benchmark at 1.5 and when I used Savage at 1.5 she got ~1700. The interactive gov made my friends Dinc2 noticably slower. Just switching home screens it lagged to the point it was hard to get into the app to change the gov.
CM7 + TheOC kernel allows adjusting voltage & overclock or underclock. You really should flash a CM7 ROM. Having it just rooted can be dangerous because you're not using a custom recovery to make a backup image, and if something messes up, you don't have a backup ROM to restore. Going to a different ROM forces you to make a backup, then there's a backup to restore if you mess things up.
Governors just tell the CPU how fast to ramp up to a certain frequency, & how long to stay there. It's hard to balance fast ramp up (less lag), and low battery drain (spend more time in the lower frequencies). I like interactive/x, find that smartassv2 spends too much time in the mid frequencies (~500) even for light work. Using the app CPU Spy helps a lot to see what's going on. Also it tells you whether your phone is sleeping properly when screen is off, which is a big factor for battery drain.
Hello,
i'm new on the Nexus S. I had a Milestone and tried pretty much every custom rom, as the Milestone stock rom was slow, unstable and outdated.
I read many times "great battery life" within the description of Nexus S custom roms (e.g. Codename).
BUT, is it better than the stock-kernel battery-life? And how much better (guess)?
I ask, because most of the Roms are overclocked and perhaps the "great battery life" is relative to those speed-optimized roms.
For me the speed of the stock rom is totally okay and it seems totally stable. I would only "custom-ize" it, if the battery life would be (significant) better – else: "Never change a running system!"
AK
p.s. Links are welcome, as i didn't find any comparison like this.
I have found stock GB rom was a battery hog. I tried a few roms but loved that CNA will pull all your apps from the market for you(I didn't have to download them all manually)
With a custom rom you can change more settings, you can change governors, you can change the cpu speeds and voltage. With deep idle sleep working your phone sips power when in your pocket. I like the Air Kernel,3.x with the scary setting, seems to use lower cpu frequencies more often.
you can find roms that are stripped down to next to nothing, these should give you better battery life then stock, to fully loaded roms that most likely will not give you better battery life.
I have my cpu set to 200 min and 1400 max running air kernel with the scary governor. scored around 2500 on Quadrant and battery last pretty good as when I just have the screen on, not doing much the cpu is running 200Mhz and the phone goes in to deep sleep right away.
try CPUspy and cool tool, CPUspy lets you see the states the cpu is using for a given time and cool tool can display cpu/power details in the top bar.
Through my ROM testing with ICS, most ROMs give very comparable battery life. Battery life relies very little on the ROM itself assuming there is no wakelock or similar issue which is because of the ROM, which in a good ROM there won't be. There may be some settings which are added or changed that have some effect, but likely nothing very major, especially in my experience.
Normally the bloatware is what drains battery with unused apps opening in the background.
Custom ROMs omit and give the option of certain bloatware.
Also some ROMs have great idle compared to stock.
But overall if u control ur mobile data, wifi, gps and sync then u can better or great battery life on any ROM just as long as its not a newer ROM that is still testing. And most custom ROMs have the pull down notifications that make it easier to control all of them.
I personally use SLIM ICS and its comes simple enough that u customize it.
Vs Nexus S 4G
Sorry for making many thread, But I'm curious.
ANd need some help
How normal is this? ...
Idle: 216/216 Screen off
No Data No Wifi No GPS No bluetooth No sync
And I'm getting drain like this? What's happening?!?!
Or are the readings just wrong?
i was about to make a thread but saw this and thought id fill in it.
Well my g2x has been quite dissappointing lately..
When i first got it, the battery life wasnt that bad. Even had data/refresh and Auto brightness and it would last almost all day.
But the past couple of months its been unbearable. I would have to charge my phone at any oppurtunity, even at work. After 100% charge i would check 30min later and it would be already at 83%.
I'm on the latest CM7 nightly, and have also tried juice defender (no use)
Im contemplating on just doing a CLEAN install of the nightly but i dont want to start all over again because its a pain.
Any input? Or is it just the crappy battery?

It could be the battery. Your case is different from mine..
My battery is tested with Battery Monitor Widget, and it says my battery is about 1540mAh.
The thing I'm confused about is the battery drain.. It's quite high. 200mAh + at 216mhz
Try clean install, don't use any of those scripts (like V6 SuperCharger), those are wakelock city.
Now, go into spare parts and check your partial wakelocks and uninstall apps that have huge wakelocks, facebook is a battery hog.
clean install of cm7?
or clean wipe of phone back to factory then root/install cm7?
Clean install of the rom you're using.

I was having horrible battery drainage also. I replaced the usb cable and ac charger and it made a huge difference. Faux kernel also helped alot. I get a little over 8 hrs with moderate to heavy use.
EDIT: wait that wasn't even related to the op but the other scenario.

Yeah, I tried a clean install...
After clean install, the only app I installed was this. And boom high usage.
all wipe first and flash or agian.
Wipe user data, /system, and dalvik cache. PM me if you're unsure where they are.

I have the same issue on my G2x. I have replaced battery with a 1800mAH and a 3500mAH extended. But the drain is the same with every one of them.
Have tried FAUX's kernel with SetCPU and the recommended settings, but to no avail.
Did a clean install (wiped user/factory reset, dalvik, cache and did a format /system) of RG2x-MIUI v2.3.16 - SWIPE NOTIFICATIONS-Powered by Faux123 CM v0.4.8 yesterday.
Battery drains at the rate of 10% every hour when idle. Even with minimal usage (15mins call time, few txt, light browsing over 4G), the battery won't last more than 4-5hrs
One thing I am curious about, do you have to run a combination of kernel+ROM over a period of time to see if the battery performs any better or are the results instant?
Most people get better battery life on OTA based roms than CM7/AOSP. So MIUI may not provide enough juice for you, but try Bionix Reloaded and tell us the difference in battery.

I has Bionix Reloaded before yesterday. The battery life was about the same, but the main issue that I was facing with Bionix was the switch from data-Wifi. For some reason, data had precedence over WiFi.
I can give it one more shot. Maybe a clean install would rectify that issue. DO you recommend any kernel/tweaks/setCPU settings etc with Bionix or just use it as such?
For the meanwhile, I have turned off GPS and using SetCPU 816/389 inscreen and 389/389 Off to see if there is any improvement.
I really don't care about the fancy part as long as I get battery life.
I recommend Faux's undervolted kernel, make sure its the one for GB btw. As for SetCPU settings (I uses CPU Master), I keep it at 216-816 most of the time, only raising it if I need it (such as Facebook, browsing, heavy games). I have the governor set to Performance.
Also, I don't have a screen off profile (but did have it set before) at 216-503 with Powersave governor, and my battery lasts more now that I took off the profile. The Tegra 2 has HW governors that more efficiently save battery than SW ones do. Not all CPUs are like this, so we are in for a treat.

Will give it a shot right now. Just to be sure about the kernel, we are talking abt this one:
[ GINGERBREAD: ]
[ Start @ 1.1 GHz, Pre Overclock / Under Volt, Max @ 1.55 GHz ]
The File ==> LGE Pre-OC/UV Kernel Version 013 With EXT4 <==
from http://forum.xda-developers.com/showthread.php?t=1102720
That's not my problem. O;
My problem is that When the battery is 100%, no matter what task I DO, it only drains -2...
But with the same setting, at 30% battery, my battery drains from -300 to -1000

Hi!
Ok, i'm not good in writing especially in english so here we go
From all kernel that has been released lately, which one do you recommend for having the best battery life in term of standby??
My opinion is Sebastian's kernel in ARHD 6.5.1
it gave me mostly 2 hours for 1%
but i have new problem now cause i flash ARHD 6.5.3 and then restore boot from 6.5.1 NAND back up and now my wifi gave me error
(but this is my problem, not yours )
Come on guys, give me your opinion
I'm currently running Hyper NonSense with the default kernel - I think it's Faux that's cooked into the ROM but unsure of this. Between the ROM and the kernel, I'm getting the best battery life I've seen with this phone. Easily have 30-50% left at the end of the day with moderate use; haven't actually benchmarked it more carefully than that.
Any update on this? My sensation doesn't even last a day...
Best kernels right now are Faux kernel
Sebastian FM
Bricked kernel
I myself have found that bricked uses the less battery, but try them yourself and decide which suits your needs.
I'm using Faux right now with HyperNonSense and I would say it's a good balance between battery saving and performance. One thing to keep in mind is that the higher you OC the more juice it'll drain. So far I've always capped my CPU to 1.24Mhz and I've never had an issue with performance. During light use I can get more than 30 hours in a full charge. If it's a moderate use, I'm still able to touch 24 hours. Oh yeah I'm using Anker 1900mAh.
