I just don't understand. Cm7 tiamat 1.1.4 smartass v2 newest radio and matching ril, no wifi and background data turned completely off. This is significantly worse than any other rom including stock. Any ideas?

Charge to 100 percent then delete battery stats.
See if that helps.
It's the best rom for battery for all others i've talked to

I've calibrated the battery twice since installing CM7 in the past 4 days. I am even underclocking with Incredicontrol at -75, but to no avail.

HMM Android system is chewing through battery.
I'm not really sure why.

Is your Android System in battery config not using roughly the same percentage?

Ooh God no...
Mine isn't even in the list.

I don't know if it will help as I just downloaded it today but this app https://market.android.com/details?id=com.freeb.automm seems like it should help battery life because you can customize how much memory goes to background applications.

@Scoobysnacks Are you using Cynogenmod or MIUI? I'm on MIUI and found that Android System and Call Standby always seem to be listed in at the top of the battery use processes (much more than Display). Whereas for Sense ROMs, Display is almost always at the top.

try a modified kernel , like tiamat

Oops sorry didnt see you already using it. Make sur you use 1.1.4 and not .5 because that kernel has battery problems you could try stock cm7 kernel as well
Sent from my Blade using xda premium

same here, android system 40%, standby 36%.
im on miui.us 1.11.4 and tiamat 1.1.5

Currently Mobile standby 47% and phone idle 45% for me. Android system not in the list.
CM7.1 and Tiamat 1.1.5, so it can't be the kernel or the ROM. Did you do a full wipe?
Try running logcat on the phone and seeing what messages are in there, something seems to be keeping the phone awake a lot judging by the blue stripes below your graph.

CM7 battery drain

Helli guys I slept for 10 hours I left the phone 100% battery now I found it 15 without any using Im using cm7 29/7 nightly with modded huexx 4.0 kernel

Is it a recent problem? due to a new install of CM7?
Check with Cpuspy if the phone enters in deepsleep.
Your plot shows a weak phone signal for some hours but this does not seem to be the cause of the drain. The slope is quiet constant over the time.
Do you have an app running in background?

I recommend using the original kernel of CM7 to not have high battery consumption.
Also recommend using the CM Stable because the Nightlys always use a lot of battery.
I use Cm7 Stable with the following tweaks in build.prop to help save battery.
# Save battery
wifi.supplicant_scan_interval=180
pm.sleep_mode=1
ro.ril.disable.power.collapse=0
ro.sf.lcd_density=240
ro.sf.hw_lcd_density=240
ro.kernel.android.checkjni=0
Hope helped you.
Hugs! :silly:

Cm7 original kernel has freezes and sods and this kernel is better although in the gps but the battery was good after i installed it for the first time then battery get worse by time i installed cm9 ultrasound 3 for testing and then get back to the cm7 by nandroid backup then the drain started
When i installed it for the first time it took 0% dor 10 hours of deep sleep next night it took 5% third night it took 10% fourth night it took 15 don't know why
How to know if I have running apps in the background?

Perhaps you should clear the battery stats ... I don't know if the NANDROID restore the batttery stats.

Normal whatsapp and other things small I mean the normal as first time I installed cm7
Sent from my LG-P970 using xda app-developers app

Strange. If it was app we would see some wacklocks. But there's none. Do nadroid backup and check on stock if the same happens. This could be hardware failure.

No not on the stock only with same cm7 I'm using now first the battery was very very very good but now no let me clear battery status and see If we can do some things
Sent from my LG-P970 using xda app-developers app

without using it only can stay for 10 hours only why????
Zeus can stand for 2% per all night but cm7 powers off after 10 hours

Zeus' battery drain
In my opinion is the battery consumption of Zeus very high, especially when the screen is on!

Best apps for battery saving

I've been using android phones from past 2 years and i found some best battery saving apps .
Here are the best battery saving apps i found -
Screen filter - it does not save battery but it reduces battery that saves battery.
Longetivity beta - this app js the best battery saving app , when i use this app on my gaalxy note , the phone uses only 2% of battery for 10hours .
Do you know any battery saving apps?
Please drop in your comments .

Try SetCPU and set it to maximum 800MHz

The Best way is flash kernel and custom rom

Just flash the HydraCore 0.7 kernel and set SetCPU to 1.2Ghz with pegasusq governor. Also make a profile for when the screen is off to 500mhz Max. I get around 10 hours of heavy usage daily. And well over 14 hours of normal usage.

Not that it matters though but I just root my phone, take those bloatwares off *using TB and install 2 apps for my battery saving thing.... - Android Assistant and battery Saver (both in google play), one as a tasker to turn off all apps that runs everytime I reboot my phone, and the other to set the maximum battery profile on what I just need my phone to use on to. Average, I get about 2 days max on my phone(with SpeedMod as well).. eg. Email and data on. I get to set my profile to turn off my wifi everytime I leave the house and turn it on again when I come home at night. Screen brightness at 20% and not using any LWP at all. Just normal static ones.
P.S. ROMS matter as well, stock ICS drains pretty much, that's what I can say.. I'm using Chrack's final one and yeah.. never been this satisfied and contented as before. That's all I can say....

Experimental Battery usage with JB Roms

Would like to ask any and all JB rom users to post any and all usage with screen shots, using Battery saver or no battery saver and witch Rom you mighty be using....just basically a referance to see what Roms are using the most batt and if you are using a batt saver, compared to the ICS roms with their usage on batt performance....

Currently I'm running the PacMan version 1214 Jelly Bean on my Vivid, the battery life actually is a lot better than it was when I was running the stock att rom. Usually under light usage (some Facebook, Amazon MP3, about 200 texts), I had enough juice to last about 19 hours before I needed to charge. I don't use battery saver or anything like that, I'd post a screenshot of my battery stats, but for some reason the stats aren't available. I'll tinker with it a little and see if I can get a screenshot of it.

Don't have pictures for ya, but 12–14 hours with normal usage. 4 hours plus screen on time. It's worse than wcx, but better than stock.

Not too bad, it did pretty good with ICS too.
Sent from my Holiday using Xparent ICS Tapatalk 2

My battery seems to last the same, during normal usage, as ICS maybe an hour shorter, but it isn't very far from when I was using ICS
ROM
JB - Paranoid Android released on 12-20
ICS- Virtuous Inquisition
JB
The only thing that I have noticed is that the charging is really slow, approximiatly 1.5 % per hour when the phone is on standby. Powered off it jumps to 30-50% per hour. However with me being IT support I need to have my phone on as a rule.
ICS- charge in standby 20% approximately.
other notes.
during continous usage JB lasts a little longer, thus by comparison in standby it doesn't last as long.
Sorry that i dont have screen shots available, however there are the stats, if you have questions I am of course here to help.

One Power Guard. never use these type of apps but I decided to try it since battery didnt last as long with JB and i saw results
Was at work but used mobile data a bit made calls & texts and usually doesnt last this long i wou8ld have to charge when i got home

Make an init.d script and put the following in it:

Will this disable the core totally?

I am currently testing SetCPU and will see if this works.

How much screen on time do you get?
Did you use it all the time before capturing that screenshot or was it idle?
Sent from my Xperia V using XDA Free mobile app

I did normal usage on it, or let's say the same as any other day. Using WhatsApp mostly. My stock ROM gives me at least 19h without using stamina mode, CM give me a good day from a new installation, but after day two I get this battery drain.

The next time it happens, take a screenshot like this, a screenshot of the graph when you first get into battery usage...and also take a screenshot of your screen on time (you get to it by tapping on "screen" in battery usage tab). Because if you get around 3:45 - 4:30 hours of screen on time, it's not bad battery life but actually maximum of what our phone can get.
