Hello everyone!
Usually I am not active on forums because usually most answers are somewhere in the vast internet. But this time I gave up.
I have a problem with my Note 5's (SM-N920L) fast battery drain. Now it even goes 20% per hour when I use it.
My phone is already about 1,5 year old and I use it a lot, so I read that might be a battery problem so I tried booting it into safe mode and it solved the problem so it seems there is a problem with some app or other functionality, not a battery. So I have factory reset my phone and it was working fine for maybe 3 days, then afternight it drained batterry ultra fast again.
I tried uninstalling any apps that I had installed the day before it broke again, but it didn't help
I have also rooted my phone previously to try to find the reason for fast drain with Gsam stats and WakeLock but I still couldn't find out what's the cause of the problem.
I've seen some posts about deep sleep issue, but my battery drain is qute ok when I'm not using it.
Did anyone have a similar problem? Do you have an idea what can I do to repair it?
Greetings,
Paweł (Paul) Sawicki
Recently I've been trying a different set of tweaks and have the best battery life I've ever had with this device.
DO NOT USE GREENIFY. As it drains the battery a lot these days.
-Rom: PixelRom v6 (Samsung based, all other roms suck for our device, this is odexed and the fastest)
-Kernel: Fuel kernel.
-Cpu governor:
Big: zzmove
Small: interactive
-Flash the lastest Magisk 13 beta.
-Download - then install the following magisk zip plugins through the magisk app:
-(Deleted crossbreeder, as it causes system hangs)
-DozeGMS
-https://forum.xda-developers.com/apps/magisk
Then install busybox (use one which installs successfully). Then hebf from the play store, don't apply any profiles. Disable the extra logging and kernel panics - set it to stay on boot.
-Battery tab - Enable improve battery, low ram device, instant doze.
And I do recommend making your wifi turn off when the screen goes off.
Welcome to three days of battery with frequent usage.

Thank you

I can only find Crossbreeder Ultra Lite. The Crossbreeder Lite thread says it's for 5.1 and below. What one is right to use?
Check system processes. I found out recently that com.android.systemui uses 15% cpu even on empty home screen and heats up my device without any reason. It was definately the cause of my battery drain. I've been trying disabling apps and unnececery options, and suddenly ui stoped draining and went down to normal 0.5% cpu consuimption. But I don't know exactly what I changed. My latest action was to update all Galaxy Apps.
Actually - don't use that Crossbreeder plugin, it seems to cause system hangs. Everything else though is fine - it'll make the battery life sing!
I also accepted this device just had bad battery life. But now it's never been so good.
IMO Samsung should have used a single processor and use a bigger battery.

Hello,
I want to publish the first public beta of my Kernel. It is based on 2.6.35.14 and should reduce the Android OS Battery usage. The Kernel is based on CF Root Kernel.
As always: You are responsible for your phone. Don't blame me, if something goes wrong and you loose the photos from grandmas birthday or brick your phone. I have warned you! The Kernel is in very early stage and has been tested only by me so far.
Features:
2.6.35.14
Root
CWM5
Compatible to Chainfires CWM App
Reduced Debugging and Logging
Interactive Governor enabled (but not set as default. Use SetCPU).
NEW Version 1.2:
- Based on KJ6 Sources
- optimized compiler flags
- bug fixing
NEW Version 1.3:
- OC/UV Support (100 - 1700 MHz, SetCPU and Voltage Control)
- additional governors (ondemand, ondemandx, interactive, interactivex, smartass, smartassv2, performance, powersave, conservative, Lagfree, Lazy, Savagedzen, Lulzactive)
- Tegrak 2nd core Support
- I/O schedulers: BFQv3, SIO, CFQ, deadline, VR, noop
- some tweaks and bugfixes
NEW Version 1.3.1:
- Removed some Optimizations in order to fix the Camera Bug
NEW Version 1.4:
- added 50 MHz
- Fixed Bug which caused removal of CWM Manager
- EFS Backup reworked
- intellidemand govenor added
- added Version Number in Version String
- Fixed Camera Bug finally
- Deactivated GPU Undervolting
- Some tweaks added again, which were removed for 1.3.1
NEW Version 1.5:
- Optimizations in Schedulers and Governors
- Maybe Bluetooth Streaming Bugfix
NEW Version 1.6:
- Voodoo Louder support
- Optimized schedulers
- new MALI drivers
- more logging and debugging (due to voodoo louder)
NEW Version 2.0:
- complete reworked cpufreq (incl. Abyss Smooth Scaling support), no more 50 MHz support
- Lulzactive V2 inkl. Tegrak support
- xz compression
- optimized configuration
- tun, ntfs, fuse support
- amazing performance improvement
The configuration is more or less Samsung Stock (except debugging, logging and the governor). Maybe I will optimize it in the future. The CWM App from Chainfire is not included, but should work on this kernel. I suggest to first flash a CF Kernel in order to root your phone and get the CWM App. After that you can flash this kernel. I recommend the CWM Manager App for flashing activities.
Please report bugs. I had a problem with endless USB Port Suspend / Resume cycles during testing, which caused the phone not to enter the deep sleep. Maybe the reason were to optimistic compiler options (it did not occur in the last 24 hours).
I would also appreciate, if you compare battery lifetime with Stock kernel. The battery statistic tells, the Android OS Usage is reduced, but results this really in a longer battery lifetime? Please observe and report.
For the Developers: The Sourcecode.
https://github.com/riversource/Galaxy-Note-Kernel
Seems logcat is not working any more.
adb logcat results in:
Unable to open log device '/dev/log/main': No such file or directory
Also no logcat tracing on the device
As I said: Reduced Logging.
Copy the following script to /system/etc/init.d/01log:
Code:
#!/system/bin/sh
insmod /lib/modules/logger.ko
Then reboot.
everything is working
deep sleep works
usb works
could not find anything negative
I had a complete crash this morning. No chance to switch on again. Had to pull battery.
Flashing was successful. Everything is working stable. I'll be watching battery usage!
Another problem I found:
I customized to files in /system/usr/keychars and /system/usr/keylayout to match german keyboard layout.
Seems the system is now only using the .kl file in /system/usr/keychars but not the compiled .kcm.bin file in keylayout folder.
Any idea?
Flashed without issue. So far after having it on for a few hours it seems like the Android OS (and the suspend event/0 processes going nuts) has stopped and the idle power drain is much less.
So, success. Otherwise for me its stable and all normal.
Very pleased.
Android os usage has dropped from 60% on average to 9%. Looks greatvso far. No issues to report.
Good job :-D

Your opinion is that this is BLOWING in terms of battery life?
Hmm, stay tuned!
will try this in a bit,but I'm curious, how many people see high Os usage?
Mine hasn't gone over 1O% since I' ve had the note.
is there some pattern of use that causes it ?
My usage has been variable.
On days ( weekdays ) when i use the phone a lot , OS usage is around 10-15%
However today i have not used the phone that much and usage is like 37% ( wow)
This is on stock KJ4 with CF root
How do you install this Do I extract it to a zimage file and then load it with cwm? which option on cwm do I use....or am I just totally wrong?
Thanks

You should flash it via the CWM Manager from Chainfire. See here:

Thanks for the info
Been playing with it, pretty decent start
I'm wondering about 3.01 now in preparation for ics... not sure of any major differences between .35 and 3 as there is with the fun I've had porting 32 to 36 on tegra.

It is starting to look that way. I had really high android os usage thqt drained the bat in 6hrs with only a moderate load.
If the bat drain was all the aos with such a big drop in the percentage aos uses, i should see a corresponding increase in bat life.
I'll monitor it and report back on anything interesting.
Sent from my GT-N7000 using xda premium
The way I understand the AOS usage is that it represents % of battery drain.
Say you charge your phone to 100 and start using it non stop for 2 Hrs.
The main drain will be screen cpu and maybe network or the app you are using.
In that case, AOS will be almost nothing, like 5%. But your battery will have dropped to , say, 70%
Now charge your phone again, and leave it on standby for as many hours requested to get 70% of battery left. This would need many hours.
Obvioulsy, because you did nothing with the phone, the main drain there is the OS itself!
So to compare the old and the new kernel, they have to be tested the same way.
Say start with a full charge before going to bed and set an alarm in 8hrs after you unplug the phone.
Leave the phone on standby for 8Hrs and check the AOS usage after those 8Hrs.
Next night, repeat the process with the new kernel and see if there is any difference.
Looking good so far. I noticed that BetterBatteryStats wake lock stats now give me "Event Log Service" as the highest wakelock, 6 minutes in 6 hours. Is this due to disabling logs, and should we freeze that service so it would stop trying to log?
Hey! I've just bought S5 yesterday and I know it's still premature to evaluate my phone's performance. I've made my first 100% to 16% with the phone and my stats were.
Phone on: 18h
Screen: 3h
Bright auto -5, wifi on, 3g on all time.
I find it is not as much as I expected but I must admit there was an update in between of the OS, and many updates in the play store which probably drained my battery higher than normally. Then I've checked tips for reducing consumption and that what I made:
- install battery guru
- disable syncs in google account
- disable updates in play store (notifications and so)
- disable some samsung apps
- disable gestures and movements
- location on power saving mode
However, my intention in this post is to gather more tips you are using with samsung rom (no root). Disable accounts or whatever you do...
Anyway, I guess I should expect an improvement in the battery life in coming charges...right?
Thanks!
Battery guru even sucks more battery than its saves, because it needs google service -.-'
I use:
Faux kernel - with my own tweaks, for hopefull best performance and battery life. OC 2.7
Greenify - to Slumber apps / System apps (Paid)
Unbounce - to lower the wake ups etc. (Paid)

I would love to change the black/gray to Pure black, to save more battery life, Gravity box could do this trick, but the app froze my phone somehow, now that its gone it works fine like before. so if you can change it do it.
Thanks! I've removed battery guru. I know that without rooting phone I may not be able to disable many things but I guess I can avoid some wakelocks coming from the pre installed software. Right? Which of them could be? Should I disable Samsung account? Any app that replaces S health in using the heart rate sensor? I think this is the only functionality I would have to keep which needs a Samsung account
Summing up , things that could make android os and system android reduce

My #1 tip would be before you look at how bad ur battery is. realise these are smartphones. and we buy them because of connectivity. why buy a smartphone if you keep turning of its ability to be smart
these phones run HD displays constant internet connectivity and all sorts of sync options
Sock12345 - I don't have it rooted yet. I'm thinking about it because I don't want to have the warranty avoided. I don't know how is the law concerning this in Spain. However, I would like to root it so that I can find out thexactly drainers and get rid of them. I will check this possibility
-PiLoT- you're totally right. Maybe I am asking too much to the phone which works incredibly well. But I have the feeling that some pre installed apps maybe battery drainers. Maybe they do not drain as much as I think...
I've received Nexus 6 from FlipKart, Its great but two major concerns:
1. Screen is very yellow (warm color) and on reducing brightness it becomes magenta. When compared to any other phone including Nexus 5, its extremely yellow. Tried couple of apps, none of them do a good job of fixing the yellows. Did anyone find a good app/setting to calibrate this screen right?
2. Battery life is pathetic: From 100% to 10% in half day. SOT is barely 3 - 3.5 hours (Greenified Facebook, Encryption off), no gaming, where as my friend gets 5hours. Sometimes phone hangs and switches off. When I switch on, it looses 15% battery. It has only been charged 2-3 times (only got it 2 days ago). Does it get better with time? or Am I having a faulty battery?
Update: forgot to mention my phone shuts down at 28% battery. And it didn't boot at all. I realized battery was zero. Is this calibration issue? Or bad battery
Flash elementalx, you'll be able to change color values and battery life is great
1. You can change your RGB using any kernel with support to it. Almost every single kernel have support to RGB LCD KCAL. Use a app such as Trickster to modify the RGB once you flashed a kernel of your choosing.
2. Battery life is subjective to how you use your device. Just because someone was able to achieve 5 hours+ SOT doesn't mean you will either because there are way too many factors that play into effect such as: cellular signal strength, wakelocks, apps installed, etc. If you want to maximize your battery life, look into underclocking the CPU/GPU frequency and flash a custom kernel (e.g. Franco) that removes mpdecision. Mpdecision is a huge battery drain and the frequencies that it selects is completely random and unnecessary in my opinion.
http://forum.xda-developers.com/showpost.php?p=57808725&postcount=7 my battery life with Franco pre-r1.
I agree that mpdecision really does drain battery a lot. I have mine OVERCLOCKED to 2.88 ghz with sensei kernel and intelliplug. And I am still getting way better battery life than stock. Just flash this kernel with intelliplug and there goes your battery issues. And you can also adjust your screen colors.

For more elaboration on mpdecision,
All Qualcomm based phones have Qualcomm prorprietary userspace binary called "mpdecision" aka m(ake)p(oor)decision. Instead of letting the kernel itself to decide what frequencies and how many cores to run, this "mpdecsion" binary polls the kernel run queue statistics and decides for the whole system the "optimal" frequency and the "optimal" number of cores to use. The concept is fine, except the decision making is done in userspace and it's 100% closed source so there's no way to tweak it and there's a latency (because all userspace binaries needs to "poll" the kernel for the latest information which is slightly delayed). - faux123

In other words, mpdecision makes your phone sit at 1.5GHz for doing the most simplest tasks, even composing a email it'll bring your frequency to be at 1.5GHz.
Download CPU Spy and use your phone, then look at CPU Spy and you'll see how much time is spent in that frequency. Then flash another kernel that does not use mpdecision then you'll see the difference, the phone sits at frequencies that makes sense for the load that is on the device.
The alternative solutions would be, Franco's Hotplugging Algorithm or intelliplug by Faux.
Battery life is very subjective.
I am still 100% stock, encrypted, auto brightness and get over 6 hours SOT every charge. Mainly WiFi, some LTE. No gaming.
I will root and switch to another kernel when I have time and see the difference. I would expect more battery.
However if you are only at 2.5 hours SOT on a full charge, I wouldn't expect it to double just by changing kernels.

Well, not impossible as it has been that way on my phone since day 1.
But i agree that it is really odd how some people are getting 3 hours and others getting 6.
I had the opposite on my Note 4 though. Everyone got 6 and I got 4. So who knows?

You only want to disable MPDecision if theres a alternative. For Franco, mpdecision is 100% removed so you don't need to disable anything.
I don't know ElementalX so I can't say, ask in their thread. If you use Franco, everything is done for you and you don't need to do anything on your part.
My battery life with LK is pretty good as well! I was able to tether for 10 hours straight and still had 22% left after sleeping ~8 hours.
So I've gotten my standby time to be pretty good but under moderate use, the device is getting warm and chewing through battery. I.e 4hrs off charger, 40 minutes of screen and only 71% left. I'm stock rooted and removed bloat. Even had stuff greenified (just uninstalled to test now). Is there anything I can do without tripping Knox to slow down the CPU a little? The native power save mode is all or nothing now - they used to let you control which features were enabled on older devices

If your rooted, download a program called Trickster Mod. (All credit to the dev) It allows you to underclock the CPU. Stock value is set at 1.5Ghz. WIthout an overclocked kernel, that value cannot change. However, underclocking is available. And since this device is a true octa-core dropping it to 1.2 Ghz shouldn't be a problem. Also you can change your governor to a conservative one. Stock is ondemand. Conservative and Performance are able to be selected. Changing your TCP congestion to cubic instead of the stock bic, in my experience, gives you a bit better battery life as well. Hope this helps.
Thanks!
The app doesn't say it supports s6, does it definitely work?
You can try kernel tweaker which is also availble on the play store. By the way we do have a Q&A forum so your questions would be better suited over there.
I can't find anything called "kernel tweaker" exactly... Also my question was about apps and this is app subforum. Sorry if that isn't correct
Hey all. I'm running Chroma 7/1 on Zen 21 right now, and I can't say I like the battery life I'm getting. What kernel have you found gives the best battery life? Or what settings? Other suggestions? Lemme know. Thanks!
It's hit and miss. We don't know what else you are running as far as apps and settings go, so it's basically trial and error until you find What's best for you.
right, it all depends how you use the phone.
me, im a heavy user, lots of browser action. but i dont do much gaming. i like performance, but i get great battery life as well(about 5-6.5 hours sot). i strictly use ondemand/deadline, no hotplugging, fsync off. also, i like despair, vindicator, and elementalx kernels, but thats just me
oh, signal quality plays a huge role in battery life as well. so does screen brightness, keep your screen brightness down. i keep mine from 15%-0$.
I use elementalx. It doesn't have better battery life than any other kernel - they are all the same. It's all about tweaks..
Setting the up threshold higher for example, will change the % of load the cpu must be under before it ramps up to the next frequency or even to turn additional cores online.
Thanks. I guess it's trial and error then.
I've been using aicp and stock elemental x with good results.
