CM9a4 FE22 kernel battery drain

In 10 hours 15 minutes of just sitting in my house with Wifi on, my phone dropped from 100% to 40%. Screen was off the entire time, sync was turned on. This is CM9 w/FE22 kernel and FE16 modem. Help me figure out what is using all the battery.
Phone was awake for 5h 55m and in deep sleep for only 4h 22m:

Wifi was on the entire time, something kept waking the phone at no set interval, screen was off the entire time.
Of the 60% of the battery that is drained, 86% of it was from Android OS. So, Android OS ate 51.6% of my battery just by sitting there, with the screen off. Wifi ate 3% of my battery, Cell Standby ate 2.4% of my battery, screen time (less than 10 minutes) ate up 1.8%, and Phone Idle ate up 1.2%. 51.6 + 3 + 2.4 + 1.8 = 58.8%. 1.2% is unaccounted for, but that is probably because Android rounds the percentages to the nearest whole number. I didn't get a screenshot of the Android OS battery usage, but the CPU Total for Android OS was 3h 44m 27s, and Keep Awake was 5h 30m 31s.
According to Badass Battery, 41.1% of my battery drain was due to App Usage.
The kernel ate up 31.1% of my battery. You can see the rest of the list...

Is there a way to see how much battery each process is eating up?

I rebooted my phone today and it magically lost 19%.
Did your led light ever come on? I forget all the wake locks.

yeah, actually the led light does come on. i should disable that.

Same story here. I would like to know what is causing it too.

Chris41g narrowed it down to pppd and wifi conflicting with each other, at least in my case. Battery life is excellent when wifi is turned off, but once it's on, battery life is terrible.

I was getting terrible battery life on alpha 4.

I am having the same issue

Same problem kernel eats 80%, currently on CM9 ( cm-9-20120628-NIGHTLY-n7000 )..

[Review] Kmashi Portable Bluetooth Speaker

This is a product review for Kmashi portable speaker with flashing LED light. The product is truly amazing, I have never thought I would get so good sound performance with this speaker.

When it powers on, a lady voice says "Connection" and when it connects to the phone it makes a sound to indicate connection is successful. It also auto turns off when in standby mode or in no use which saves it's battery charge to drain out. The LED flashing lights are a beautiful and unique addition to this product which makes it even more amazing with beats.

Anker power iq and voltageboost test

Hello guys, i just got an anker charger with poweriq and voltageboost tech.
I'm gonna test this charger with my nvidia shield tablet k1.
I'm going to charge from 14 to 100 with 1ft, 3ft, 6ft and 10ft cables and compare times
The times should be the same no matter the cable, that's voltageboost tech.
In the next few days I will compare power iq vs quick charge 2 using my LG g flex 2.
update 22 April 2016
Nvidia shield k1 14 to 100 2h 19 min 1ft cable - - aprox 97 seconds 1 percent - -
Nvidia sheild k1 14 to 100 2h 21 min 3ft cable - - aprox 99 secodfs 1 percent - -
Quick charge 2.0
LG g flex 2 10 to 100 1h 31 minutes 3ft cable LG g flex 2 quick charge 2.0 charger - - aprox 61 seconds 1 percent - -
LG g flex 2 2 to 100 1h 31 minutes 6ft cable LG g flex 2 quick charge 2.0 charger - - aprox 52 seconds 1 percent - -
Poweriq
LG g flex 2 8 to 100 1h 42 minutes 3ft cable anker poweriq charger - - aprox 66 seconds 1 percent
LG g flex 2 8 to 100 1h 48 minutes 6ft cable anker poweriq charger - - aprox 66 seconds 1 percent
The next tests will be
Nvidia shield k1 6ft cable 14 to 100
LG g flex 2 anker poweriq 6ft cable 10 to 100
LG g flex 2 anker quick chage 2.0 carger
LG g flex 2 anker quick charge 3.0 carger
Iphone charger, galaxy tab charger

Managing / monitoring quick charge

Hi guys .
I was wondering if anyone has come across an app or a method of telling which QC charging profile our HTC 10s are using?
As an example, my HTC is currently at 50%, and due to the fact I will be going out after work, I decided to plug it in to top up. My desktop charger is a QC 2.0 charger from Tronsmart - and supports 5V/2A, 9V/2A and 12V/1.5A.
Once I plug in, the phone registers the charger as a quick charger, and booting up Ampere reads a charge speed of 2460 mA at 4.217 volts = 10.3 W. Even if I take the standby drain into account (measured by Ampere at -360mA) = 2820 mA x 4.217V = 11.9W.
This seems a little ways off from the 18W charging profiles.
So, is there a set of environmental criterium that has to exist for the 18W profiles to kick in? if so - what are they?
or, is Ampere possibly unable to measure the amperage or voltage accurately?
or, is this effectively 18W, and there are 6W worth of losses from resistance or heat? (1/3 in losses seems a little high for me?)
PS, the cable I am using with the tronsmart is a USB A to C cable from Belkin, very thick gauge too.

Ampere can't see past the phones own battery charging circuitry and know what it's being fed.
If you really want to see what the phone is being fed, get yourself a USB power meter.
This guy sells those "YZXstudio" meters http://www.ebay.com/usr/f-t-2000

And in before you ask, yes they're QC3.0 compatible because backwards compatibility.
@Haldi4803 has ordered/received a power meter as well, don't know which one he got but he reported this in the megatech thread.
3. My Powermeter is here <3 gonna open my own Thread soon. Sadly the Bluetooth App failed so I don't have the charging measurement from 30-100% from last night. But.....
At 30% it charges with 7V !
071010,022593
7.1V 2.2A = 15,6W
When at 100% Idle Voltage is about 6,3V
When connected to the Powerplug and on 100% Battery you can Benchmark as much as you want, the battery does NOT Drop. So you can use this to control if Trepn Profiler is correct in Powerdrain.

Judging by the "bluetooth app", did you get one of these YZX meters Haldi?

Bingo
Soldered the additional Bluetooth module on and it's awesome!

QuickCharge.... like every other charging technologie tries to safe the Battery from harm. Therefore only on the lowest battery level you will be charging with a low of Watts. On 50% ? Well.... i'll tell you the next time my Phone is empty Benchmarking in Progress.....

Max charging rate for Galaxy Fold?

Just bought the Galaxy Fold (coming in the mail) but I'm confused on what is the max charging rate for the Galaxy Fold. I know the included charger is 15w but upon some research I'm getting mix answers. Some reports say 15w is max and other reports are saying 25w is capable if you get the right charger.
Can anyone chime in?
PS. I did look at the official specs on Samsung's website and a lot of the info are inconsistent.
Thanks

I cant remember what the note 10+ charger was but that charges phone in like an hour 30 from 0 to 100 1 hour 50 not used the fold charger lol also have a Qualcomm 2.0 charger that takes 1 hour 30 to 40 prob 2 hours from 0 to 100

So, I just did a test.
I have 3 chargers here. A 25w Samsung charger from my note 10+, a Razr Quick charge 4+ and the Samsung 15w charger that came with the fold.
Fold is currently at 33%. When I plugged in the 3 different chargers the time showed on screen till charging is complete was:
25w Samsung: 1 hr 10 mins
Razr QC4+: 1 hr 10 mins
15w Fold Charger: 1 hr 28 mins
So it would look like the fold does use a bit of extra charge that the 25w and quick charge 4+ provides and is not limited to only 15w. I don't think it's using the full 25w though, as the note 10+ had a 4300mah battery and charged in 58 minutes in comparison to the extra 15 mins it takes on the fold.
Good to know though.

Double post whoops..

I went ahead and bought the 15w wireless charging stand since the Fold supports 15w wireless charging officially and it came with the same charger as the note (25w and I am assuming to charge the phone + built in fan)
Here are my results using the Ampere app (by no means this is a scientific test):
25w PD charging:
