Debugging bad battery life

Having battery woes?
no matter what ROM you are on, these simple steps will help with debug.
Install CPU spy and badass battery manager.
Start the apps and reset statistics.
Let phone run for a few hours.
Open CPU spy.

See deep sleep?
An idle phone should be spending most of the time in this state.
If so, you are fine. All is well.
If not open Badass.
Here click on the bottom line which shows app usage.
Here is what you see. Kernel is at the top for me as there are no rogue apps.
If your device is not going into deep sleep and kernel is the one taking most CPU, it can be ram issue
NOTE : THIS method is android generic. Not specific to note.

I had Facebook show up under kernal because it was accessing my GPS. I use better battery stats which offers a really good way to show you what is using your battery. badass didn't help in that case, it only showed that the kernal was using the battery because GPS falls under it. Better battery stats showed me it was the GPS and then it also showed me that my router wouldn't let me phone sleep, so a static IP fixed it.
Badass is nice, but it's very generic when it comes to android specific functions that are being called upon. It's only good to show apps that are using the processor, not the functions or processes that the apps are calling up if they do so.
Regardless, thanks for the how to guide.

Wifi on 24/7 (small interruption was used for tethering), and still tweaking so next charge will probably last 3 days

^^

More idle time, wifi available all time
2d 7h
2h screen on
Cm11 nightly
Mi2
Or less idle more useage
1d 2h
4h 13m screen on

On Ivans AOSP 4.4.4 I get 2 days of usage with 3-4 hours of screen on time.
Using 2G and wifi, I only use 3g when I need it (quicksettings makes switching very easy).
On xiaomi.eu is a thread with LOTS of battery usage information by a lot of people using different roms.

Have you been playing asphalt? If not the app is misbehaving and you may need to force stop it.
WiFi seems high as well. Have you turned off wifi scanning? That's helped a lot of people I think.

Gaming uses a lot of battery and more so when is a high end one. So the drain is normal.

Well, i can't tell for sure why you have that drain, but you seem to be using LTE+Location. Both use tons of juice from your battery. High end games also drains a lot of battery. I suggest you to check what is waking your phone from sleep and force close it, or just use greenify.

Battery life?

How is the battery of this tablet?
Watching Netflix and YouTube how many hours of display they can?

How much battery consumes 1 chapter of Netflix 45 minutes with 60% brightness?

battery is draining twice faster

Hey everyone,
my Note 4's battery (SM-N910F) is draining really fast. I bought 3 new batteries (1 samsung from their site and 2 rav power) and my battery still only holds for like 3 to 4 hours (instead of the whole day as before).
Can you help me figure out a fix?
Thanks !
Android 6.0.1 is running.
Version number MMB29M.N010FFXXU1DQL2.
Baseband N910FXXS1DQA1

3 -4 hours when using it? That is great. However, if standby is affected then you need to see what is running in the background and affecting the battery. Use BetterBatteryStats and or Gsm Battery monitor

no, 3-4 hours when almost not using it ! Before, the battery was lasting all my work day. Now at lunch, it's done.
I installed Gsm battery monitor, here's what I get:
{
"lightbox_close": "Close",
"lightbox_next": "Next",

"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}

Do a search on android system battery drain and try some of the fixes. Something is running causing the drain. Google or other backup or something constantly syncing etc.

Finally, I did a full factory reset and now the battery is back to normal!
