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.

[Q] can someone explain to me about battery info?

Hi guys, I never really understood the meaning of those hours when i click on my battery status. On the pic shown, it says: 1H 10m 29s on battery. Can someone explain to me what that means? It seems very low to me, and i just got my phone 2 days ago. It is the octa-core version i9500.
I also see that media takes up most of the battery, and I dont know what that is.
Plz explain?

It just means your phone is for 1H10M29S unplugged from the power plug :fingers-crossed:
If you click on media you can see which apps are contained in media and stressing your battery.

having wifi on, and using my phone for normal usage and its allready 77% in just 1 hour... I hope the battery does improve as what some people say if you have a new device.

In 3 hours i have a loss of 7% while using Whatsapp and Instagram, 3G is activated.
Did you activate auto. Sync (Google, Facebook, Dropbox, Samsung stuff), Gestures, AirView and so on permanently? If so, please switch them off, this will help for a longer battery runtime (only if you dont need them all the time).
How a about the display brightness? automatic oder manual setting?

#offtopic What is that font & needed to root to change it?
#ontopic The time will not reset after you plug it in for a short time.

Getting bad battery life from maps?

I got the phone yesterday and rooted it.
I never even touched maps once and it used a lot of of my battery.
I might have used Google now and S voice once to try it out, maybe the maps is updating from that?
How can I stop this?

I think you just go into your maps go to settings and turn off the location services. It'll still be able to locate if you have it off.

You can also convert it to user app in Titanium Backup, and then greenify it.

more than likely its because your maps is tracking your location. for latitude or for location history. try disabling all those features within maps.

Thanks guys did the disable location thing

It might have something to do with Voice Typing. Try disabling Google Search from Keyboard Input Methods. Or try clearing the data of Android Keyboard.

I get the same issue.
Noticed it because my device got really hot and I saw all four cores constantly above 1,5 GHz (Galaxy S4).
If you look in Apps you will see that Google Keyboard is constantly starting dictionary service. Do not disable the keyboard because the device gets unusable due to Force Closes.

same problem
I have same problem with Google keyboard. Just now I restricted background data for wi-fi and mobile and I noticed that my phone cooled down very fast. I'will test it today and let you know what I found out.

Fixed problem with keyboard draining battery by restricting it's background data both on wi-fi and mobile. Before I got about 2h of SOT on full charge(100%-0%), and now I got 1h 45min SOT on 20%(100%-80%)

over 4gb.... I usually strict my data usage to certain mb. That way I don't have to worry about it. Anyway thanks for the heads up.

[Q] Huge battery drain. Any ideas?

Hi
These past few days the battery has been draining ridiculously fast.
I charged it before bed and then it's basically sat with the screen off since.
34% battery gone to AndroidOS and Android System.
Better Battery Stats hasn't been very helpful as I'm not rooted. It does say that it's been "awake" 100% since unplugged.
Here's some shots. Anyone know particular culprits?

Delete everything inside your android folder in internal memory and memory card.

That would wipe all of my game saves etc wouldn't it?

Seems a background processing is keeping the phone awake. It might be because Bluetooth is on.
You can try using Greenify to Force Stop most of the apps (Does not require root). I find that my phone does not wake up much after it Force stopped most apps.
Do note that you would want to leave messaging apps running or you will not receive messages.

I have a Gear S connected by BT LE but I thought the point of BT LE was it's low power. ..

Ok. Update. Having turned off the Gear S and killing it's connection, that wasn't the cause as it's still 100% awake whilst screen off.

Ok. It seems to be Samsung's Gear Manager app. Uninstalled and it goes into deep sleep straight away. With it installed, even when not connected to anything, it keeps the phone awake.
