I have an LG Urbane paired to my Verizon Note 3.
I'm running Android Wear app version 1.1.1.1901499
Any thoughts on how I should interpret this chart from the Android Wear App on my phone?
It looks like it's saying from my last full charge I have used 61% of my power. 7% while the watch was idle, 4% to light the screen, 3% for Android Wear, and 1% for Fit.
What about the other 46%? Where did that go?

Edit: Apologies, I've misread your post.
7% of the 61% power used was expended while the watch was idle; 4% of the 61% used was to power the display; etc.

Lot of people (me included) are confused about how to read and understand battery statistics. I think it's possible to find misunderstanding in many of the battery usage threads I have been reading, making discussions muddy.
As an common example people often think that a high OS-System battery % equal high OS-System battery usage/drain ... but I don't think this is true!
Let me show two examples:
Example 1:
On battery 26 hours using 43% battery or roughly 1.65% battery per hour.
Screen 23%
Android-System 22%
Android-OS 21%
Voice call 10%
Standby 9%
Newsreader 7%
Phone not active 6%
Google services 2%
All together 100%.
Example 2:
On battery 10 hours using 50% battery or roughly 5% battery per hour.
Screen 55%
Android-System 8%
Android-OS 9%
Voice call 7%
Standby 5%
Newsreader 7%
Phone not active 7%
Google services 2%
All together 100%.
One should think that Android-System and Android-OS drains more in example 1 than it does in example 2 ... but I think it's the opposit!
Example 1 Android-OS have been using 21% of those 1.65% --> 0.33% per hour.
Example 2 Android-OS have been using 9% of those 5% --> 0.45% per hour.
Would someone PLS verify that I understood it correctly, or feel free to correct me if I'm wrong
You are 100% correct!

Disclaimer: This is what sounds logic to me and what I think is how it works. Now I have no specific knowledge about battery so this might be completely wrong.
First read this, or don't but it makes it easier to understand.
Now going on in that trend lets say you have a gas tank of 100l liters (same as 100% battery). In your first example 43% got lost, so 43 liters. 21% of the 43 liters got drained by the hole. Thus 43*,21=9,03 liters.
Second example: 50 liters total drained, 9% by the hole. Thus 50*,09=4,5 liters.
So the first example drained more.

Yes you might be right ... but what about the time factor?
Agree that in example 1 OS uses more juice than in example 2, but over a much longer time. Meaning less average drain!
The "leaky" battery debate...

Factor in the "leak"(drainage) over time and you can see the OP's point.
Scenario 1 : 9.03/26h = 0.35/h
Scenario 2 : 4.5/10h = 0.45/h
The actual RATE of loss/drainage is more important.
This might give someone with lots of spare time to tabulate a league table of battery dissipation/drainage for different ROMs/firmwares. Or more interestingly across different devices using stock ROMs (eg SGS2 vs Sensation vs Atrix vs LG2X, etc)
I agree, but the first example drained more but slower and the second less but faster.

..and hence the battery in the first scenario will last longer than the second, assuming both start at the same capacity.
We are now on the same page
no matter what, there is a bug! compared to other 2.3.3 phones, my nexus one has been unplugged 7.5 hours right now, with 1 hour of screen-on time. and my android OS is reading 2%, 2 minutes usage. that is TWO MINUTES. that is the way its supposed to read. i've gone 24 hours with 12 minutes usage for android OS.
somethign is just not right with the SGS2 reading...
I need to revise maths once again
but this discussion somewhat helps to clear the confusion
I noticed about 3ish weeks ago that my battery was depleting at a faster rate than before on my GoldenEye 4.2.2 ROM
Here's where it gets strange...
Regardless of my screentime I think that my battery depletes the same...right now I have had 56min on screen time and my battery is 48%
I tested how much time I could get out of my phone, and I can go from 100% to 0% with about 4ish hours of screen time....
I seriously feel that I'm getting more efficient usage by having my screen ON rather than off...
Here's my stats right now
Screen: 37% 56 minutes
Cell Standby 25%
Media Server 15%
Device Idle 7%
Skype 5%
Android OS 4%
Android System 2%
Seriously, whats going on? why is my battery being depleted so much with so little screentime???????
It's something Google did with the new update of Google services. No one knows exactly what it is tho.

Stock 5.0.2 version B200.
Android OS taking 50% battery juice all the time even over night.
Any ideas ?

How long is the battery lasting (in hours)?
Android will take up 100% of the battery usage if you do nothing with your phone (that is, the OS will discharge the battery just keeping the phone working).
I would expect Android to take up more of the battery usage overnight since you aren't doing anything else with it. A "percentage of usage" is just the share that entity is using relative to the other things running on the phone.
Yeah, That makes sense, but how much draining is reasonable over an 8 hour period at night ? 2% per hour is reasonable ?

This means the phone would last two days hours if you left it alone, and Android would be responsible for only half of that drain by your previous observation. Doesn't sound unreasonable.
What's using the other 50% of the battery overnight?

I will review and report back.
Here's the battery usage screen after 7 hours:
https://drive.google.com/file/d/0B0O3XF-vHiCKZDFXYzNEWWtsLW8/view?usp=sharing
That's too much, I'm getting like 3% drain over the night (5% with the wifi but no real synchronization). Do you really need NFC and Bluetooth during the night?
PS. Try to restart your phone
I turned off NFC and battery draining slowed down significantly.
normal or not? 80%. after 10 hours.

I've been getting huge battery drains with Android System and Android OS taking up about 32% of battery life the past 2 months, with no big change in my apps or usage. Seems to even happen in flight mode and screen off....I'm starting to fear it's some google app that broke for our phone, trying to find the cause using BetterBatteryStats ATM.
I encountered 22% Android System usage and it's draining my battery. After a full charge, it takes 10 hours I didn't touch my S3 Neo and the battery is 72%.
I don't know what is the problem. Because the OS should work transparently with minimum CPU and battery usage.
Hello,
i got a friend of mine a moto G7 (as i always had good expierience with moto G5/G6) and after some month (5?) he told me battery life was very poor. today he finally brought me the phone to take a look...
the phone was fully charged in the morning, now (after 5 hours) it has 55% left. no data, no bluetooth, no screen time...
battery usage says the phone will run for 5 more hours with 55% left...
battery usage only lists these:
System 11%
mobile network standby 4%
Display 3% (22 mins)
standby (4h 53mins) 1%
what can i do?

Without knowing more than you've written, if this were my device I'd be tempted to backup everything and then do a factory reset.
Otherwise a more detailed battery monitor might help:

Hi, try to disable Digital Well Being completely. I did it and the battery life increases a lot.
