Better Battery Stats

Or you could do a Google search. Why do we need to spoon feed you ? Millions before you have reported battery drain issues.

Go into WiFi, press the menu button, select advanced, turn off SCANNING ALWAYS AVAILABLE.

What makes you think I haven't already? As you correctly said, there are "millions before you" that have reported these issues, all with various different causes, some resolved, mostly not.
I was wondering if the expert eyes of this community could spot any obvious causes.

Thanks. Based on my understanding, It's not WiFi that's draining all the power. I've always have WiFi Scanning Always Available, and the power drain doesn't finish the entire battery overnight.
Also, even with SCANNING ALWAYS AVAILABLE enabled, the Awake Percentage is normally 25% - 30% not 75%.
It's something else.

And before anyone asks, I've also tried disabling Location Services.

I'd try the WiFi for a day or 2 just to see if it helps. I recalled having the same battery drain issue when I first got the device. After turning it off it has helped a lot. Now it could simply be a bad app that you may have downloaded. Hope you figure it out

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.

I'm not the only one having sensors wakelocks

this is so annoying.. i've been spending my times with these wakelocks but still no luck

Hi,
I'm really interested in this also, because for some time, bunch of "sensors" wakelocks stays at 40%. I kinda expect this to be the "always listening" double tap to unlock feature, but I'm also interested if everyone else is also getting it.
Also, what percentage of deep sleep do you get when phone is idling (overnight)?
did you try disabling all the gestures from settings?

I disabled all sensors and also knock feature.. Yet still no luck
I have those wakelocks, too, but I really don't worry about it. This phone uses less battery with the screen off than any phone I've ever seen. Whatever the cause of those wakelocks, they're not having any significant impact on battery life.

possible solution of kernel wakelock!!!! developers plz read!!

I don't know what actually happen with my G3 D855. Been using it for 2month yet can't get ride of this sh*t. I'm so pissed whenever I check the kernel wakelock. this is the reason why our devices cannot get last longer than other flagships.
I'm sure it'll be related with the kernel.. I've tried kitkat both stock and aosp and even the the 5.o lollipop, flash the rin kernel, still this happens. also i've been googling for hundred pages.. i really can't find the solution. Plz developers here don't ignore my request. or am I the only one that has that kind of this weird wakelock?

i have 50+ ipc wakelocks in my phone
I believe this is not a true wakelock, because while mine's also showing >100% of usage for ipcXXXXXX_sensors.qcom and other stuff, I can actually get decent deep sleep. If these were true wakes, I doubt the phone would go to sleep at all.
Probably just an error in a way BBS is reporting the usage.

Because system reported it as wakelock to any app that asked.
Check your phone's sleep time vs these "sensors wakelocks". You will find out that you couldn't possibly get this much sleep if those wakelocks were real.

Need to replace JuiceDefender

I already have Greenify to keep apps under control.
Running CM12.1 on Lollipop. Juicedefender's mobile data feature is totally broken. I loved having that as it A) kept my data usage low, and B) really did a superb job on battery saving.
Is there any other app that controls the radios automatically? That is what I really need!
Thanks!

DS (Deep Sleep) Battery Saver worked for me in the past... I just leave data off 90% of the time anymore as I'm usually connected to WiFi.

Thanks, I'll look into that. I thought about manually controlling the LTE, but I know I would forget to turn it back on. Which would be bad since I mostly use web apps for messaging lol.

"Unaccounted" process draining battery

Hi everybody.
It's more than a month that I'm experiencing a battery drain coming from an "unaccounted" source (reported from the app System Panel 2). I haven't put on charge the phone last night, and this is the result (see attachment and link). Any idea about what is draining and/or how to solve it?
Thanks in advantage!

Why is my screen using 200mA or more, for 5 min, each half an hour?

Ok, quite weird for a screen for having this much drain, are you on Oreo, there is a problem with undue battery drain, https://forum.xda-developers.com/galaxy-s8/help/samsung-s8-oreo-battery-drains-fast-t3772609 try keeping the brightness down and reduce the resolution. Good Luck, EDIT: It might be your android system, after checking my phone the android system and screen take most battery.
How long does your phone last on a full charge?

Let's say around 12 hours if I don't use it a lot.
Hi did anyone find out what the unaccounted accounts to. Still showing the same in 2021
