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

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!

Weird battery drain ! help needed !

Hello everyone ...
I have faced my first mysterious problem with my N7000

Almost 10 % per 15-20 mins

I get deep sleep with Bluetooth , data off ... except wifi (On)
I tried other Rom like criskelo v11.2 - same drain ...

PLEASE HELP ME OUT ... I'm not so good with tech ...

Install cpu spy and check if your phone is getting into deep sleep or not
Or flash a stock rom and see if it is fine
If it is entering into deep sleep and still experiencing the same,then it might be a battery problem

Yes i do get deep sleep !!

Is there any app to check battery life ... so that i can confirm !

did u check in settings battery... what is using the most battery?

I flashed a pure stock ROM and updated via Kies ...
Now i think the problem is solved ...
Anyhow a pic of the present

There is no particular app to check the battery life
It seems your battery is fine now
There might be some app or something else that made your battery drain and you cant judge your battery life as soon as you flash a rom
It takes some time for the rom to settle down

As per the pic, in that 2hrs on battery u have been using the screen for a long time so.. but the drain isn't very much now. Good.. should have seen this pic on the previous rom u had on

THanks for the help members ///
Thank you

No it is not..usually screen consumes the most battery. Wipe dalvik cache, that will help in reducing the amount consumed by your Android os..

10% used i almost 10 hours. Phone was not used at all (just sitting idle) so it is perfectly normal that system takes 1st place in usage stats.

LOL Yeah It was idle the whole time, I have been sleeping a lot.

I don't understand! Why does it matter which app/process/thread is consuming the most battery? Are you having problems involving battery discharging within minutes? No? Then let the process consume how much power it wants...
I do not respond to tech support via PM

if he has 9hours off usage and just lost about 10% its normal that he couldn't have turned his screen on long time.
the screen-on time i think is really short... if you dont use your phone much, like you in this case no one would wonder that only aOS consumes the power ... just by syncing and keeping your phone ready, look at mine (ignore the offline time).
My Android OS also used more than 50% off the power but after that long time its okay, this means only, your not looking your facebook acc each 5 mins

Make an init.d script and put the following in it:
echo "0" > /sys/devices/system/cpu/cpu1/online

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.
