Only 130 ma charging with every charger.how can i fix it? Overall best kernel.

I'm running viperos aswel on my j500f and seem to get values of between 600 and 700 ma while charging though on the lockscreen on the battery charging status it says slow charging. I don't really know what your problem might be. What version of viper are you using and what model j5 do you have?

J500F using los 14.1

That's weird man it should be working fine for you maybe reflash the kernel and wipe dalvik and cache afterwards and hopefully that should work. Are you using TWRP 3.1.1-1?

Yes im using 3.1.1-1. I will try to flash it again and see but now im busy.

Switched to viperos and now charges 700-800 ma .

Been running this kernel for about a week and everything was fine but all of a sudden yesterday I was unable to receive calls. Everytime someone tried to ring it would go straight to voicemail without any notification. I don't know was it something I did or is it ROM or kernel related but seeing as you have the same model phone and your also running viper would you mind just testing this out. I don't know if it's working again will test later

Ok ill check. Also,when i press recents or back buttons sometimes the vibration is louder than normal . Why?

I noticed that too but I think that was happening to me before I had this kernel so I don't think it's to blame here. I don't see it as a problem for me though. I still think this is the best kernel I have ever used kudos to the dev

I didnt said its the kernel lol. But sometimes my phone has heavy lag and nothing work until revoot

Oh sorry my bad. Ya I know exactly what ya mean I have had the same issue myself but since switching to this kernel and viperos most lag issues were solved. It's like the phone thinks it has more ram than it actually does and ends up overloading itself and we experience heavy lag and random reboots. I use the magisk module sysconfig patcher which is a battery saving module but also helps to reduce the ram usage and works extremely well at reducing lag and thanks to this kernel I have better performance by doing some tweaks/overclock using kernel aduitor. Maybe give some of these a try and see if your performance increases :good:

 

[opticalblitz10]

Great kernel in overall in terms of battery life ! :good: But, occasionally, the phone will become extremely slow and won't resolve itself unless I reboot it. But nonetheless, thanks OP!

Turn off cpu hotplug in kernel adiutor. I think it gets stuck at 1 processor and its laggy as hell. But its still best kernel for lineage.

Kernel for J500M based LOS14.1

Your warranty is now void.
I'm not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired, because the alarm app failed. Please
do some research if you have any concerns about features included
before flashing it! YOU are choosing to make these modifications, and if
you point the finger at me for messing up your device, I will laugh at you.

So here it is. After testing for a few days I've decided to give out builds of CM 12.1 kernel with a little bit better CPU management.You may see improvement especially when you're not using 3G/LTE as it seems to drain battery almost as fast as before (depending on the use ofc). You'll get much better battery life on wifi though. You may tweak the settings using some kernel control apps but the recommended setup is already applied.


Features:

+ Bricked hotplug driver - turns off CPU cores if the CPU load is not big enough to need them.
+ Powersuspend - a driver that should turn off unused hardware components when screen is off
+ Quickwakeup driver - it allows some tasks to wake up the system to perform certain actions without fully resuming it
+ Min. CPU freq 200MHz (CM12.1 has it set to 800MHz but it seems we don't need it that high after disabling CRC checks)
+ Revised interactive governor target_loads to clock CPU more efficiently

Changelog:

07.10.2017:
- First release rebased on @vince2678 kernel source and device trees (Will work only with his Los14.1 builds from now on, don't even try any older ROMs available)
- Added some tweaks by @Bulgaricus

24.07.2017:
- Rebased on newest LOS kernel
- Reimplemented some of tweaks previously reverted due to conflict (The most important being Display driver update, refresh rate should be better now)

- Merged upstream changes (new power hal compability etc.)

19.05.2017:
- Merged base kernel updates
- Enabled thermal core control
- Change throttling cpu temperature from 60°C to 80°C to avoid performance loss
- Enabled CPU_BOOST config
- Kernel now should boot on both LL and MM bootloaders (needs testing)

18.05.2017:
- First release for Lineage OS 14.1

- Changed default gpu governor to simple_ondemand to avoid frequency bug described in #16

06.01.2017
- Initial release
- Added bricked hotplug driver
- Added powersuspend driver
- Added quickwakeup driver

Can you fix me the LOS14.1 kernel for J500M?

 

[alirezaanik]

Sir
Will it work on rr5.8.5 for j500H

 

[garylawwd]

Sir

Nope it doesn't

Facing Issues

1. Locking or Unlocking Screen , Charging or Discharging Notification takes more time than usual
2. Abnormal lagging during incoming call when screen is off

Facing this problem after using the phone for some hours

Sent from Samsung J500F

 

[1nikolas]

1. Will the lineage 14.1 version work with rr nougat?
2. Do I have to set something on kernel adiutor to get the 4 day battery life or it's out of the box?

 

[Hamidltf]

Hi

No bug for j500F/ds ???
