solid battery drain with cybergr rom ver.12 - Nexus S Q&A, Help & Troubleshooting

I am experiencing poor battery life with cybergr rom version 12.
settings are governer - ondemand
min cpu freq - 200
max cpu freq - 1000
kernel - tried both matrix 19.5 as well as air 4.
battery drains by 10% in every hour.
I have to recharge my phone thrice a day.
I did fresh installation but it did not solve my problem
please help.
I really love this rom

BetterBatteryStats. Also, try a new ROM if need be.

Battery Health

Could you people please post the average battery life for our phone(number of months before we need to replace the battery itself).
My phone is just over a year and battery drains very fast. Have tried all kernel, ROM etc... but of no use. I think I have to replace the battery.
I'm on Kyrillos v9.4, kernel G3Mod v2.3
83Mhz, Max 800-1200MHz, Scaling: Ondemand
In call: 83min, 400max, Scaling: Ondemand, Priority:100
Time profile: 1AM - 7AM (here put the time you sleep), min/max 83MHz, Scaling: Powersave, Priority: 99
Screen off: 83min, 400max, Scaling: Ondemand, Priority:98
my battery lasts three days with normal/heavy usage
after flash the rom do a full charge the battery till 100%, do a batery calibartion with this app and next full discharge the battery. Next do a full charge again nexto to a full dicharge. Do this cycle 2/3 times and your battery should be ok. Try this and tell the results..

My battery has 1year and 4 months..and it works pretty good
Running Vivek's ROM, battery last for 26-28 hrs, 1 yr old phone !!

Battery Drain while sleeping

I fully charged the phone to 100% and turned it on at 7:45 then I went back to sleep. I woke up at 10 to see the phone at 95%! Now, I'm currently using the Anker battery & I'm running on ARHD 3.6.13 with faux123 v0.2.8 kernel. The brightness is at its lowest & auto-sync is off. What should I do?
I recommend using Battery monitor widget Pro to see how much mA is phone using during sleep and when screen's on. Then install Better Battery Stats ( http://forum.xda-developers.com/showthread.php?t=1179809 ) and figure out, what is eating your energy
also, try undervolting

What's undervolting?
Undervolt makes your cpu use less energy. for undervolting try using system tuner pro or faux clock (here's link for faux's RootzWiki: http://rootzwiki.com/topic/4550-app09-beta-snapdragon-dual-core-oc-control/ ) But be aware that not every CPU handles heavy undervolting well. Do nandroid backup, then Start with -25mV.

Try changing cpu governor to intellidemand (faux's kernel default) and min speed for cpu to 192. It may slightly improve battery life.

Hi,
When I was on 3.6.x,it was suggested that I try a Bricked kernel,which you can find HERE
I am not sure which one,but they tended to be more battery friendly than faux.
Read the thread.
You might get some valuable information.

OrDroid 7.1.0 battery life

Hello All.
How is the battery life on the new rom ?
I have the 6.1.0 Rom and its killing my battery , any one has the same issue ?
Was trying to switch Kernel no luck ...
Honestly, best for you to judge for yourself since everyone's configurations differ.
Also, might be a bit early to tell since I don't think the ROM has even been released for a day which means most people may not have even used their phone enough to have an opinion.

Well, it all depends on how you configure the installation. What options did you choose?
For the one day that I have used Ordroid 7.0.1, I've been quite happy with the battery life.
SetCPU 1188 Max 192 min
governor ondemand
scheduler cfq
ordroid 6.1.0
Kernel 3.0.28-RCMIX
Base 11.69.3504.00P_11.22.3504.07_M
Build 1.78.401.2 CL58751
The ROM was released not very long ago. So there can´t be a right answer until now.
The Phone needs some "Complete empty" -> "Full charge" cycles to show the battery properly. A battery wipe is not the right solution.
Beside the CPU, GPU and stuff setting, lots of battery drain is caused by the synchronisation. So check if everything is really necessary.
Live background wallpaper need energy as well. So with some setup, you can bring your sensa to 1,5 days without surrender on anything.
With stock ROM it´s possible to get 2 days, but dont watch the screen to often ;-)
Well, I've figured that you can get maximum battery without much performance compromise if you configure it as:
Sweep2Wake {Yes (no capacitive backlight)} or {No}
ZRAM {No}
3DGPU Overclock {3DGPU OC disabled}
2DGPU Overclock {2DGPU OC disabled}
Governor {badass}
badass config {Balanced}
I/OScheduler {cfq}
Maxfreq {1566 MHz}
Minfreq {192 MHz}
Screen off max freq {486 MHz}
Keep the screen brightness at 35%. Switch off WiFi when not in use. Remove your HTC Sense account unless really required.
The lesser the number of accounts you have, the better it is.
Hope this helps!
Now its rebooting in a call

Thanks il do this when installing the new ROM
Any news guys ? Did any one tested the new rom for bat life ?

I configured the new ROM exactly like this .
Already did one full discharge .

[Q] How do I use no frill CPU?

I want to overclock my phone. I have doom kernel v14 installed. I installed no frill CPU on my phone. The min frequency I seleted was at 300 MHz (approx) and the max was 1.4 GHz (approx). Does this mean that the phone will automatically go between these values if I run a heavy app (eg GTA 3)? And what does the 'governor' and 'i/o schedular' mean and what does it do? My current settings are :
sio - I/o schedular
Performance - govenor
Min - 245
Max - 1.2 Ghz
Governor : Smartass v2
Mine is like this.
and what about the i/o scheduler? And what does govenor and i/o scheduler mean?
I'm also on Doomkernel v14 and my battery is draining so quicky. Its dropping 5% every 10minutes even when I'm using any light application. I have SetCPU and my sttings are Max 1401MHz and Min 134MHz with smartassV2 and deadline. Although speed is amazing but battery performance is terrible.

Performance governor is a "special" one in that it goes to the max. clock speed, and never uses the min., or any frequency in between. You can do that if you want to do benchmarking reliably, but I'm not sure it's good for battery life.
http://forum.xda-developers.com/showthread.php?t=1663809
^ That page explains all the governors, but from what I can tell from using Cool Tool onscreen system info app, "lagfree" on Doomkernel seems to be a higher performance governor like you'd expect from the name and not how he or she describes: it seems to scale down only quite slowly from a high clock, I'm guessing to eliminate any possible lag while scrolling the interface that might result if it scaled down quicker. And we don't have anything relating to multiple cores
Anyway, I think I saw you say you were on JokaWild as well. Looking at the Joka init.d scripts the SmartAssV2 parameters are tweaked towards performance and it comes as the default for the rom, so maybe try that as a more balanced option than Performance governor.

I wondered as well if v14 was not as good as v13 3013 for battery life, but better for performance, but 5% in 10 minutes is a lot. Have you tried using the BetterBatteryStats app to find an explanation? Has it got better just through subsequent use / recharging?
Battery life really sucks on jokawild (actually in all CustomRoms).
I have mine like this (r800a):
-smartassv2/sio or bfq
-.62 stock rom with a couple of build.prop mods
-64 baseband
-juice defender
-brightness around 25%
-supercharger v6
My phone has been for like 4hr and still with 100%

Was it charging? That's impossible. I left my phone idle,lowest brightness and wifi off for about 30 minutes and it dropped to 96%.
I have deep sleep enabled,juice defender,

Undervolting/Underclocking

So recently I've become too lazy to constantly charge my Captivate and began to experiment with undervolting/underclocking it. Has anyone found optimal voltage for battery life? I've currently got every step of 200mhz down 100 volts and underclocked to a max of 800mhz. I'm on Semaphore kernel 2.9.5sc.

There isn't a optimal setting as all phones act different. Testing is the best you can do.
which cpu governor are you running? that may have more effect than underclocking/undervolting on battery life.
user Stempox has a nice post on cpu governors here
http://forum.xda-developers.com/showthread.php?p=28647926
the screen on time and data/gps traffic, and apps that keep the phone awake, do more to effect power drain than other factors. so, if you manage those, and choose the governor that suits you preferences, then undervolting and underclocking aren't needed, IMHO.
you can tweak the governor settings with Semaphore manager, if you really want to do that too.
the thing is, you may end up keeping the screen on longer than you would at higher cpu speeds, which would counter any battery savings. also, undervolting can increase the error rate, which means further delays while phone is awake.
hope this is helpful in your pursuit of fewer charging cycles.
