Hi i am having battery drain problems. My battery was working fine before like 10hours or more then all of a sudden it last like 7 hours on a full charge. After 5 hours its already in the 30's. I have ARHD 3.6.4 installed & faux123 0.2.3r_2 kernal. I installed faux clock to control the voltages. so right now its not undervolted because my phone cant handle it but my frequencies are at 1.08ghz max clock. I would like to know if i need to calibrate my battery or what do i check? I would appreciate the help Thanks.
You need to get an app to monitor your standby current. The one made by 3c is pretty popular.
Next, you need to see what it idles at. It should be low...Less than 100mA/Hr. (I see around 30mA/Hr or less).
If its high, then something is using it. Check that data. sync, wifi, and GPS are not on when not in use.

Hi,
Faux has released a new version to deal with the bad battery drain.
Check HERE
I'm running nscollab 1.60 with Franco kernel and was wondering if anyone's got some good custom voltage settings I can test out for a stronger battery life?
Essentially I'm a data user. Usually on the screen 4+ hours of the days, running market, fb and browser and of course texting.
Currently I'm messing around with smartassv2 200/800 deep idle off, BLN off, and kernel default voltage and I'm about to run my first battery calibration ...
Thanks on advance
EDIT: another side note is I've noticed my screen gets pretty hot now. When I'd run stock GB it wouldn't do that.
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.
Hey XDA,
I'm running PixelRom 1.7.2 and Trinity TEUV and my phone is almost always running at 1000Mhz, which is causing terrible battery life. Even if I'm just idling at my launcher, it will go that high... Anybody know how to get it to stay at lower frequencies? Oh and my governor is Ondemand and scheduler is Deadline. Hope someone can help...

teuv runs at 880mhz.
its possible that an app or a background process is active. try this free app from the market, its called diagnosis https://play.google.com/store/apps/details?id=eu.thedarken.diagnosis&hl=en
I thought it did too, but NsTools and CPU spy both give me: 100Mhz, 200Mhz, 400Mhz, 800Mhz, 1000Mhz, and 1096Mhz. I will try the tool from the market (yes, I still calls it the market)

1096... thats not teuv, that the t11 kernel. heres the latest teuv http://goo.gl/5JwMT im using this one at the moment
My thanks good man, that was the one I was looking for, now I feel quite silly :3
Right now, just at my launcher, cpu is switching from 92% to 100% usage :s

if you just booted, it should(for about 2-4 minutes) then it should drop. unless you have an active live wallpaper, an app thats not written very well, or a process thats gone wild. try that app i linked, let it run for a few hours, maybe you can find the cause.
My phone had been on for a few hours...
Also, I flashed TEUV, and I don't think my phone handles it very well (TEUV has GPU overclock). Once I booted, it gave me a black screen and said: (Application) has stopped working for every app on startup. This happened twice, so I went back to Matr1x and battery is still terrible...

sounds like a bad download of teuv.
Bad download? I flashed it properly and it booted fine, until after the "optimizing applications" screen
is this the first charge since you flash the kernel? If it is, let the battery run out, charge it full and take a look at it again. I find that ICS really take a full charge to stablize its battery... my first charge after flashing a new kernel has always use a lot more battery than the second charge.
Alright, I'll try that... Also I went back to aosp+ because I really like it.
Also, android system is always using 20% cpu, even on idle..
I remember performing some tests with frequencies and deep idle - I wanted to find out the minimum frequency required to run music player screen-off with few concurrent processes. I remember reading how 400mhz is the optimal frequency for deep idle but cpu spy would always report it cruising at 1ghz and cross referenced with nstools DI stats, it was supposedly in deep idle. With DI off and bumping up the frequency to 800mhz, 1ghz took up the majority of operation time. Long story short, whatever combination I tested did not garner desirable results. That was a couple weeks ago, though. I've since given up on figuring it out.
Wait, are you having the same problem as me?Ive lost 5% battry just by having the screen on for 9 minutes...
Hi all,
I have been using the ONDEMAND CPU governor for quite a while on my SGS4G running CM9 (Team Acid's version, the final herring one), and I have just gotten used to the 12-14 hour battery life that I have had ever since I switched from GB back in August 2012. However, most of the frequent users here recommend the SMARTASSV2 governor, so I tried to use that yesterday to see if battery life was enhanced.
If anything it seems that my battery life got worse (see attached picture). I am a moderate phone user in general; I use my phone for texting mostly, and sometimes I'll look something up on the Internet, but no music, WiFi and GPS are always turned off, no overclocking/undervolting. I recently purchased a new battery as my old one died about two months ago.
I was wondering, is there any governor for the CM9 ROM that is particularly good with battery but doesn't completely drain performance?
(Also, I tried to use the LZ kernel before, but it seemed to cause many more problems than it fixed.)
You've got some pretty bad wakelocks going on there. See how your phone is awake even though your screen is off? That is an issue. Also how much screen on time did you have on that run? Get Better Battery Stats(free on XDA) then fully charge and look at what wakelocks are occurring. You might also want to consider UVing if you want better battery life.
Also, if you're a fan of ondemand, I highly suggest moving to ondemandX, which actually does deep sleep when the phone is off.
But that will only help if you fix the wakelocks first. So follow hechoen's advice and your phone should be way more awesome.
Downloaded BBS today, we'll see how it goes.
