Hi everyone,
I've been running MiniCM 2.1.5 (nAa -06)for a few months now and it runs pretty fine and it's very nice to have Gingerbread and so on.
But I'm very disappointed with battery life and I don't see why it is so bad.
I understand the MiniCM should have similar if not better battery life than stock (2.1) firmware but I don't see how this can be achieved.
I always used to have 2G/3G enabled, and with stock ROM my battery would last up to 5 days with minimal usage. With MiniCM I don't get over 2 days. With normal (low) usage, my battery now lasts about 30 hours.
When the battery is empty after a minimal usage cycle, I have something like 49% cell standby, 45% phone idle and a few % display, which basically means I'm not doing anything with the phone and there's no app running in the background etc.
Switching to 2G only (and other famous battery saving tips) will give me some extra hours, but still nowhere near stock battery life (with 3G/2G all the time).
I have no tasks running that should drain battery,
I have also wiped battery stats (using the BatteryCalibration app) with no noticable effect. My voltages are displayed between 4.15(100%) and 3.65(0%) . Shouldn't it drain down to 3.2?
What are your mini battery lives?
What are your voltages at 100% / 0% battery?
How to make MiniCM last as long as stock ROM?
I never get any more than 14 hours on Flame.GDX, also on MiniCM7pro I got roughly 12 hours.
I dont think theres alot you can do. JuiceDefender an apps like it may be able to help you find an hour or two longer

I have returned to stock 2.1 after a lot of experimenting.
I have tried:
- MiniCM7 2.1.5-7 with nAa
- GingerDX with nAa
- MiniCM6 1.0.2 with stock kernel
I have found that all of them use a lot of battery, though i can not see why.
They will all result in ~<50h standby, while stock 2.1 can reach ~100h.
I wonder if this is some SE secret, or if one can achieve this with custom rom, too.
i have the elegant white rom,its awesome low ram consumption speed etc.
BUT first to change stock rom(original from manifacturer)i could play 2 hours and 1/2 sometimes 3 without trouble with battery at 30/35% left now i play 5 mins and my battery goes from 93% to 87% in 5 min
so 6%x12=72%battery lost in 1 hours its bad really bad! i also installed the battery fix but notthing!in idle without playing i lost 2/3% per hours so this is good.
someone have my same trouble? it is normal?if so i should install back stock rom?
if i get stock rom again the battery should be fine?
the elegant rom is on stock 2.3.7 i had 2.3.3 when i bought this phone
sorry for bad english i have not much time
thx everyone
(already done calibration)
to full charge it takes 1 hours max is it normal?

i said:already done
done 2 days ago after let phone shut down and charged until 100%
Roms based on CM7.2 do drain battery massively compared to stock so going back to stock would help.
Battery callibration does not help - see Here
Same problem here... Living with it cuz stock has just become old and lazy
But if you really want battery switch to stock its way better than cm

There isn't a noticeable difference in both versions in terms of battery life. However, 5.7 has better performance and is noticeable.
You can try underclocking to something like 730 MHZ and save a decent amount of battery life without losing performance. Check this OC kernel out:
OC zImage
Also, use Cyanogenmod, ADW launcher without customizations is faster than the stock touch-wiz UI launcher.

For all those who r shouting that battery calibration doesnt improve battery.. Did the XDA said it improves battery life?? Do u ppl know wats the meaning of calibration?? Calibrating means adjusting something to the accurate value.. Not improving the value!! Even we never said it ll improve battery life.. Battery calibration just calibrates the reading to more accuarte one. So let the ppl calibrate it. Else leave. It ll automatically gets adjusted after 1 or 2 week.. U can see urself the change..

Yes, many members on XDA said that callibration improves battery life. The battery indicator on your status bar does not use batterystatus.bin. It does not automatically adjust after 1 week or 2. It re-calibrates every time you charge!
Read the article posted by XDA for more:
google-engineer-debunks-myth-wiping-battery-stats-does-not-improve-battery-life/
well i dont know about you all
but on my phone battery percantage isnt that accurate
cause when i unplug phone from charger and just open game or do something battery percantage goes to like 90%
but when my battery percantage is low like 18% it holds 30mins on 18%
I've tested many roms here and stock rod do tend to have better battery life, but... When i tested the RAZRv3 by TeamCooper, it had extremly good battery life.
When i got my Ace it had froyo, that lasted about 2.5-3 days. I upgraded to gingerbread official, battery lasted about 1.5-2 days on. Then i tried several custom stock roms and they all lasted about 1-2 days.
After that i started testing CM7 (both 7.1 and 7.2) roms and most of them lasted 12-18 hours (i used the wifi disables 3g function and some other tweaks to last the battery longer otherwise those roms would not have been usable)
Then i got to the RAZRv3 i used it for 2 weeks and the battery was amazing, it lasted easily for 3 days with no other tweaks than "wifi disables 3g" and also the performance was good. No lag!
Then i tested the CM7.2byFAT and the battery was awful but i really liked the rom so i keep 3g disabled when i dont use internet (all background apps use 2g internet) and now the battery last for 2 days.
As i've tested.... 3g takes really alot of battery in CM7 roms but in RAZRv3 (cm7.1 based) it worked like a charm.
So.. Everyone who wants really good battery life should test RAZRv3 that can be found here: http://forum.xda-developers.com/showthread.php?t=1478807

do battery calibration.
install battery saving apps.
do undervolt.
change your governor.
disable animations.
lower brightness.
use 2g instead of 3g or turn of data if you dont need it.
disable wifi if you dont need it.
check auto sync settings.
In recovery (clock wolrd mod or xrecovery) go to "advanced" menu and Wipe Battery Stats. Confirm and Enjoy ;D

if your battery is hot, FC will be very bad.
you can:
1. change to 2G instead of 3G. i found that prolonged actively using 3G will get your handset heat up and then your battery drain very first;
2. turn off your handset and restart again. it may help.
these are from my own experience.
Do the callibrate thing as mentioned above...u can use battery saving apps like..
Juice defender, battery dr saver,any task killer from market..
Delete app dsp manager...as it is reported by many user that it drains the battery heavily by running in background...
I had similar issues, maybe it is related. See my post:

Hi all,
Since I started using Lite'ning ROM v2.1 I noticed that my battery was draining very fast.
I went to my battery use and I saw that "Android system"was using 44% of my battery. Wake time is almost 6 hours...
Is this a known bug or is there a solution to this?

If the rom you are using is not yet a fully stable rom then it could have battery drain problems, although battery drain is usally how you use your phone. Look what apps are running when you notice your battery running down fast, as it could be one of those.
When im at work i actually only use whatsapp, and sometimes facebook while im on break. But my WiFi is off all the time then, only whatsapp and battery monitor were active. With 2.3.4 this wasn't a problem and my battery would be 60% when i came home...
Either google wakelocks and how to pin-point them, or wipe and install NO apps afterwards, run it for a day and if the same problem go to another rom till it's more stable .
What works fine in 2.3.4 has no garuntee's that it will work an experimental ICS build of any sort.
i have similar problem. my galaxy is on wanamlite 9.6, which base on LP7. after 5 hours of not intensive using, i have 65% battery left, android OS use 68% of this battery, most of time my wi-fi is off. when is on, drain battery very fast, over night even up to 20%. when i was on ginger bread it took around 6% - 8% with data and wi-fi on.

Do you have many widgets?
Especially Beautiful Widgets and Fancy Widget (moreover if you activate the meteo forecast) will constantly drain your batter in search for your position. Wifi uses less juice than 3G connections.
Happened to me back at GB 2.3.4. Battery went down to 60% in 3 hours (at the office I'm on G...so even worse cuz the battery compensates for the lack of coverage). After I removed Fancy Widgets from the screen everything went back to normal.
Don't have any widgets as far as I know, only the clock and twitter...
Today battery is know at 26% after 11 hours on battery. Process stil at 39% battery use.
I searched the web and found that there are a lot of users having this problem, especially with the Google Nexus.

Hello every one,
I am facing poor battery life with my x10 mini pro. Even I had my battery replaced recently. But still, the battery life is just about the same.
I tried following things...
1. Turning down the brightness down.
2. Turning off the data, background sync, 3g
3. Uninstalling the apps that runs on background
4. Deleting battery stats after installing new ROM (CM7 2.2.0)
I typically use my phone for 1hour of calls, 30mins of browsing, 1hour music playback, <20mins of gaming. And the battery will be drained in less than 8 hours.
And, another weird thing is, the battery fills up very very fast. It will take like 25mins to get to 100% from <15%.
Please, guide me what to do. This has been a serious head ache for me. Will flashing back to Eclair, Donut will solve the issue?
Thanks.

I am having the exact same problem!
I suggest flashing back to MiniCM7-2.1.9, my battery life was REALLY good on that version. But I updated to v2.2.0 yesterday and now I have the same battery problem as you. The rom does run faster and I also noticed a few bugs fixed, such as the keyboard light, but battery life is just really bad for me.
If u dont use dsp manager then remove it,because many users hve reported that dsp manager drains battery
Install battery dr saver from market
It has option of full cycle charge for charging battery properly

Done that already, still the same. Already know about Battery Dr Saver, but I don't think it helps this problem.
I also installed Badass Battery Monitor, it's really detailed and shows a lot of info. It's showing that the display is using up the most battery, but I have it idle most of the time.........
agree!
at least someone or two has same problem with me.
i just flashed cm7 2.2.0 over these 2 weeks.
well i noticed the battery drain alot faster than stock eclair.
i'm looking forward to see the solution...

done that already too, except I use smartassv2 governor and my max is just stock speed at 600mhz.
I basically applied every tweak that I could find from every topic, and believe me they do work, on v2.1.9 at least.
It seems that most people have the same problem on v2.2.0, the radio somehow keeps draining battery. I noticed that it used up 33% for no reason, whereas on v2.1.9 it was around 2%.
BTW I dunno if it makes a difference if I use smartassv2 or interactiveX, but most people said that smartassv2 is better since that's what nAa uses, so it's more compatible. I don't think changing the governors matter though, I've used Badass Battery Monitor for 3 days in a row now and it shows none of the apps are draining power. Even using Android Assistant shows that my phone is idle 94% of the time, where the System uses 4% CPU and User uses 2% CPU. So I do believe it's gotta do with the radio, somehow this rom isn't using the kernel that well I think.
Then it wil be good idea to stick to 2.1.9
YES ! im not the only one wooo, i signed up just to thank the creator of this thread <3 ok so i think it is the minicm7 2.2.0 problem, because i never had it before ! BUT i am using minicm9 now, and anyone confirm that our batteries work better with this? because ive noticed a slight improvement with battery in MiniCM9, i love my mini, i need to fix this battery problem ! i even got two batteries thinking my batterys was f***ed, still only gave me about 5 hours worth of battery max !

I suggest going back to CM7 2.1.9. It's very stable for me and battery drain is so low that my phone can last almost a week on standby without much usage, it's great!
I would stay away from CM9 for now, and wait until it's more stable. So far, I've read that many people are experiencing a few bugs here and there, so I would wait until after a few new version releases and try it out then.

well, if you're using CM9 or CM7, you have no choice but to use the nAa kernel.......unless you're asking which kernel version, otherwise you pretty much don't have a choice.
I'm pretty sure it's not the kernel either, CM7 2.2.0 drains a lot more battery compared to CM7 2.1.9. They both use the same kernel, so it has nothing to do with that.
i used cm7 2.1.9 and i got 4 hours battery life, with wifi off, 3g off, and all i did was txt thru whatsapp with 2g and i was at the movies for 2 hours anyway, and no its not my battery cause i bought another one, still the same thing im getting frustrated ! gonna try original kernel and rom

I installed cm9 mini, but phone was lagging and battery life was poor. Now i installed cm7 mini 2.2.1 and it runs a lot better than cm9, but like most of you say, i also have the battery drain issue...; during 9hours of sleep my phone lost 30% of battery that's really enoying. Stock 2.1 SE rom loses about 7% during 9 hours of sleep.
So most of you recomand the 2.1.9 instead of 2.2.1? And which kernel should i use? Is there a possibility that the kernel i use (ana 14 ) drains the battery so fast? if i install 2.1.9 should i use the ana 14 kernel, or a lower version?
thx
