Terrible battery live on cyanogen

Since I rooted I've been getting horrid battery life. I used my phone for 10 minutes today texting and the battery life's consumed 7%. This is not good.

Check in your sync to make sure your calendar or contacts ect. aren't stuck trying to sync. This happened to me, and phone was dying in a matter of a few hours.

Mine is like that too I was thinking about switching to Another since I hear that Rom gets better battery life.

There are several existing battery threads. You should ask questions in there.

Hardly used my phone for 40 minutes today and down to half battery life. Can't somebody throw me a bone here?

You could try flashing one of the undervolted kernels from IntersectR or Diet. I noticed it helped a fair bit on the Cyanogen rom. Another option could be to switch to the Enom 1.8.1 rom. I'm currently running the Enom rom with IntersectR hybrid kernel and get fairly good battery life.

I had this too, flash any other kernel and it seems to fix itself. Intersects is a good call.

Same here, man

I flashed this kernel:
OC/UV kernel + HTC_Camera Addon for 1.8.1
and this rom:
TheOfficial_Nexus1_v1.8.1_update.zip
from this thread:

Is that the kernel that's being praised for having good battery life?

I'm running this combo, and I get 10x better battery life than on Cyanogen's!

Good to hear. Ill report back with my findings after a few days useage!

I was having battery troubles, but I just charged my phone fully then wiped the battery stats in recovery and have had great improvement.

Is there such thing as a desire ROM that has good battery life for the N1?

sorry, Cyano506 has great battery live... you must be doing something wrong..

yeah I must of installed a cyanogen from a different person...
....hey--wait a minute...

Battery CM 506
..this is not too bad for 506...

Thats what I am using now with the addition of juice defender free which gave me a small but noticeable boost in battery life. These things together gave me the juice to make it through the day without scrimping on my usage, before I had to either scrimp or charge during the day to make it.

well damn. I am currently looking for a new kernel. What are u running? I have a kernel from late January. From what I hear there are several good ones out there with better battery life. I am running 5.0.6 also

I don't understand. Look:
I've hardly even used it :S

since I posted that picture I haven't touched my phone, and here's the difference:

[Q] ROM for best battery life?

Edit: go ahead and move me, wrong forum...
What is the ROM that you guys have experienced the best battery life on? I had great battery life on one of the Cognition betas right after DG started using Froyo, but I don't know which one .
I'm using Perception Build 7 and I get a strong full day of use, but I would love to get more. I usually keep certain battery-draining activities to a minimum (e.g. auto-updating apps) so I would like to see even better performance, battery-wise.
So what's your experience with battery life and different ROMs?

Any of the latest cognition roms were best for me. I find that the ported roms are never quite as good.. but im using them anyway for the speed.

I found the insanity rom with the cogkernel was a pretty good combo. The rom was minimal and the kernel was just uv and not oc. It was pretty good. It rivaled the battery I got with frankentwiz and the unhelpful uv combo,Which ill miss forever T.T

Moved to Q&A.

i find the assonance ROMS have decent battery life

Axura with setiron 1.4.3. Tried with dgkernel and causes sleep death. Perception yields good life also

I just flashed 4.3, going to see how it does!

Suddenly bad battery life = battery gone bad?

Basically, a few weeks ago I flashed assonance 5.0 and my standby battery life was terrible. The battery would die by the time I got out of school which is around 7-8 hours of standby time.
So hoping to solve this problem. I flashed the captivate version of doc's rom and I have the exact same battery life. I have recalibrated the battery many times as well.
Sooo, do you think my battery has gone bad?
And if so, any good places where I could get a spare?

Many have posted eBay has some good deals.
I still suspect that many of these phones were shipped with crap batteries hence the differences with people using the same roms having much different battery life.

Well the thing is that my battery life wasn't terrible before. Or not this bad at least :x

Have you at least tried reflashing to stock to see if the problem is with the roms or with your battery?

Not for an extended period... but the thing is I read through some of the rom threads. And if it was the rom people would be complaining about battery life, but no one is :/
In fact, it is quite the opposite...

kernel related or bad battery!!!!

Well i am using Glitterball's latest kernel before Firebird. Or the stock kernel that came with the Doc's Captivate Rom 7.0
Either way, there has been a huge drop in battery life and I do not think it is kernel related, because on the Assonance 5.0 rom, i was running Setiron's 1.4.7 kernel with the exact same problems with battery life :'(

This is highly dependent on how you have your settings on your phone.
1) Wi-Fi constantly looking for an active network connection? At least have it go to sleep when the phone goes on standby. I only turn mine on at home or otherwise need and have access to it. Otherwise its off.
2) GPS running all the time? Personally, I rarely ever need to use it, but it runs great when I do.
3) Display at recommended brightness or higher? Recommended or less is best as far as saving battery power. I like mine all the way down. Don't need/want it any brighter.
I even tend to use only darker wallpapers as bright and lighter colors pull more power on AMOLED screens. This makes a little bit of difference. How much I don't know, but I do know that it does. Sometimes the above settings like to change on you. It's a good idea to check 'em once in a while.
While it's usually always around 60% full when I go to bed, I still charge my cell every night.
I have found that the speedmod kernel is real good for conserving battery power. Not downing other kernels as they're all real good. Speedmod handles battery consumption better in my experience.
Have you installed any new software that might be accessing the network checking for updates/feeds, etc?

1)I always had my Wifi sleep policy on never. So its not what is affecting the battery life
2) Never have GPS on unless i need it. Heck, when i need it, it never works.
3) nothing that i didnt have before.
Basically, I haven't changed anything to cause the decrease in battery life.

Your two biggest drains on battery are WiFi (especially when consistently seeking - any new access points where you leave it on standby all day?) and your display. Could it be your battery? Sure. Go exchange it at AT&T. They shouldn't have a problem exchanging it for you

Well the thing is. I have never had this battery life with my Wifi settings left untouched. So yeah, i will probably get a new battery from AT&T tomorrow and report back if it was the battery or not :]

give this thread a quick read, its more based around 2.2.1 roms but you could find some good information

For milestone? I would say that the 01-25 leak is the best by far.
The rest are pretty evenly matched (the CM7 base roms are mostly the same, etc)
Sent from my Milestone using Tapatalk

On the ShadowMOD the battery life is comparable to stock 2.1. At least on build 3 - build 6. On other mods (FroyoMod, Cyanogen) it is generally lower, if you do not tune it yourself.
Leak 01-25 is not bad too, but seems a bit less stable.

How to tune it ??
I heard that froyomod has a pretty good battery life. Is it true ??
Sent from my A853 using XDA App

James91, I've meant that shadowmod seems to be better in battery life just from the moment of flashing. When using the froyomon they recommend to use it's "battery calibrate" script, or delete batterystats.bin manually, and use task killers, and so on.
I was on froyomod for 5 days and never got more than 24 hrs on battery (non-intensive use). But I did not use "calibrate" script, because I a m not sure in it's safety. On shadowmod I have 40+ hours.

Thanks for your reply
I have just tried froyomod but unfortunately I got some errors on internal memory
and I turn to shadowmod again
The battery life of shadowmod (b3) is OK.
Since it would automatically kill tasks and reduce power consumption.

You dont need scripts to tune our phone. Use the 'bump charge' trick. There is a lot of talk about this in the CM7 thread.
1 power off phone
2 plug into wall charger
3 remove battery
4 wait for ? To appear (question mark)
5 put battery back in for LONG charge
6 flash any rom with full wipe.
This will ensure battery calibration on new ROM.
But honesly, if battery life is your thing: use the 01/25 leak. I am not sure why people disagree. The ROM is not flashy at all, but battery is at least 2x better then closest ROM. We have 4 milestones at work and everybody get at least 36 to 48 hrs of HEAVY use. Most cant get more then 12 to 16 with other ROMs.
Ppl that want battery life use that rom, ppl that want features, etc...use CM7 or others. Although some people are now moving back to the leak as themes are avaiable for it and a suprising amount of work is going into it.

I'm using Cronos 1.8.1 now and I'm really happy with it.
It's pretty popular among Milestone users, too bad you didn't include it.

stock roms for sure, I'm using the latest O2 leak & it's excellent in terms of power management.

I didn't include Cronos 1.8.1 coz I have heard that this rom has obvious battery drain.

[Q] Best ROM/kernel combo best battery life w/3G is turned on (Android 4.0 & above)

[Q] Best ROM/kernel combo best battery life w/3G is turned on (Android 4.0 & above)
Hi guys, as per thread title -
I'm constantly on the move and usually do not have access to a charger for the day, and I rely heavily on 3G for my job. I don't wish to go back to stock Gingerbread, and will at be on Android 4.0 and above. 3G seems to drain a lot of battery.
Be it flashing customer kernel or going to the extreme tweaks, do share your thoughts here! V30J was a good ICS rom with acceptable battery drain, but it has its own set of issues (mainly freezing randomly and not waking up). But that's my benchmark of battery life, as I got almost 10 hours with moderate usage (no wifi, no GPS, minimum brightness etc with Pimp My Rom).

Since your a local, I bet or kiasu(Singapore Attitude). Or maybe not. Anyways, The best for battery life is V30J. Or not. When I used it, its very power savvy. But take note that the performance is poor

=.= kiasu.
yeah perhaps haha but for one I don't mind a sacrifice in performance as long as the rom functions and doesn't drain battery. However V30J as mentioned had its freeze issue and that is a problem that I may not be able to accept.
