Stock Samsung S4 Wall Plug + Stock Cable, this should give you a current rate at range 1.5A-2.0A (Consider resistant)

Seeing from your results, there is no such problem with your phone perhaps

Change cable

The wallplug is spoiled when it doesnt give an output as per stated on its specification.
Can check the output amperage using Multimeter

No chance, rooting will trigger the knox

That bold part, yes it happened to me quite frequent. Mostly it will shuts down when i am using Camera.

Im using Stock rom, de-bloat a bit, tweak with Init.D script a bit. With fast launcher.

Explore XDA Dev's forum for all information, you wont regret once your phone is like a kite.

Have you tried Uncharted V2 ?? It was based on the latest NE4 firmware

Nope, im on stock rom&kernel. Just some tweaks in build.prop and Init.d

Mine was not reboot, but sudden shutdown. It happens when im using Camera only. Not sure what was triggering the shutdown but once it did, i need to plug in/re-insert battery to turn it back on.

I read somewhere where it was the firmware fault and maybe hardware too. But dont really care rite now, gonna flash Uncharted Rom v2 after this

Haha, currently flashing V2, will report back to you.

Im thinking of making my own custom rom

Yeah maybe, im trying the newest firmware for i9500, see if it solves the problem

Still in planning phase. Im testing the latest NE4 firmware and it seems just perfect.

You can dude? Repacked

It is a known bugs for S4 KitKat 4.4.2 (NC2/NB2/NC1) Firmware, the latest NE4 firmware does re-solve the issue.

You can wait for OTA upgrade to latest firmware NE4 or can flash through ODIN, i experienced the same thing like you and once upgraded to NE4, it is solved

Seems like there is an issue when youre upgrading your firmware, maybe corrupted file.

Can just flash fresh stock firmware through ODIN, i think Wiping/Factory Reset through recovery wont work as your firmware is corrupted. Need to flash fresh firmware files in ODIN, kies may gives you the same problem again

Yup, click PDA and choose your firmware files, Before connect your phone to your PC, boot into Download Mode

Recommended to use the latest release of Odin v3.09.
Make sure all option is un-thick except Auto-Reboot & F.Reset Time.

They will, Malaysia as usual will receive any OTA a bit late than others. Yup, yours is NB2.

No need to thick/choose bootloader.

I personally flashed Note 3/S4 using ODIN a couple of times. Never thick that BL options at all.

Thick BL is not compulsory but it doesnt bring any harm if you thick it either. Why?

Applying bootloader flash is compulsory when there is a change/render in the bootloader files. In case of samsung, based on their changelist of each firmware (even from 4.3 to 4.4) , they never state any change in bootloader so it is not compulsory.

But i train myself to thick bootloader sometimes, when upgrading from 4.3 to 4.4
Eventhough i knew if i didnt thick it also doesnt bring any change.

My advice is, do not flash any roms through recovery, possible is, you end up bootloop'ing.
It is obvious that your stock firmware flashing procedure was halted (based on the pic quoted by you).
We dont know at which part of the flash it was halted, it might be the kernel/bl/system.

Flash stock firmware by Odin first, try to download stock fw until successful. Just to avoid any sad story.

Uncharted V2

Lulz, im an i9500 user Not for i9505

Uncharted, it was based on latest firmware tho

Im not sure about i9505, but you can drop a visit at XDA dev forum there.

What the heck happen dude? Care to explain more? We able to help you here

You need root access to inject custom recovery. Stock unrooted binaries doesn't allow custom recovery

Seems like maybe because of your battery lifespan is near to its end already. Or maybe there are some heavy bloatwares running in the background

What does it show in the battery menu in Settings ??

Your Nova Launcher restarts is because 3rd party launcher doesnt happen to be in the memory list, so the system will kill Nova Launcher in terms of the need for extra memory (when it is needed). This is normal.

Usually i will use build.prop to force my launcher in memory. So that it will not be killed in any way.

About uncharted v1-v2, not soo sure about that, maybe you can just ask the devs in the thread

True

Okay before changing the battery lets take a look at your regular usage first.

Can post some battery screenshot? In Settings > More > Battery i need your screen on time and everything.
Maybe can identify some bollocks apps that kill your battery

Ive mentioned earlier, avoid MIUI. In my opinion, it is loaded with tons of bloatwares and wakelocks.
Ive tested for 3 devices already and all results the same.

Actually i have no idea about i9505 but ive been lurking for a while in their thread.

I cant find any minimum mod-ed stock rom based, but i think this one you can give it a shot.

Honestly saying, its just good enough for me. It depends on your usage, my usage is quite heavy browsing and games. 10 Hrs on battery ( 3 Hrs SOT//1.5 Hrs Clash Of Clans//1.5 Hrs social ).

Im using custom rom btw, with my very own tweaks here and there.
The latest firmware for S4 3G (NE4) have a better battery life too.

Honestly saying i miss 4.3 much more on GS4. Battery life is above excellent. But 4.4 kitkat is not that bad btw

Im making my own version of custom rom, NE4(i9500) based. With minimum mods, tweaked for battery and performance. Special for LYN-ers S4 user.

Who dares to be my tester?
