Samsung Note 3 overheating

[ILI-BIG]

Hi. My Samsung Note 3 is overheating for no reason. I did put thermal pad on the chip. It cooled down a little. But it still overheats and turns off. I underclocked CPU 1900 to 600Mhz and phone becomes very slow. What should i do?

Before I start. I am going to pref this with. My knowledge of phones are limited. So don't hold it against me. 
It prob trying to do something and that something new phones can do but knowing how old the note 3 is. It could be struggling.

The Samsung Note 3 is turning 10yrs old this September.

It's probably overheating because it cannot handle all of the background processes of modern firmware.

Firmware is software for the hardware, which doesn't change with android updates, or rather, the device hasn't had updates in at least five or six years, so that can't be it.

What programs do you use on the device?  Have you tried enabling stock power saving mode?

 

Does the System-on-a-Chip or SoC have thermal compound on it, maybe a different brand would work better.

 

Gamers Nexus has some videos about thermal compound performance.

 

Are you using more programs, or new programs that were not yet developed when the Note 3 was released or in that four year span of updates?  New software is probably collecting lots of data.

 

Try installing (not for the web browser) duckduckgo app, and in its settings enable

 

app tracking protection

 

This will inform you of what apps (even pandora) are collecting data and it also blocks that network activity before it can upload it.

 

This could at least help you pick better apps that aren't spying on your use.

 

Try F-droid and use apps from there.  There is antennapod for podcasts, Fennec for Firefox with restored about:config, RethinkDNS to combine with a local Pi-Hole or a cloud-based NextDNS account to block all the google / android telemetry.  Firebase is the only acceptable domain that loads, it helps developers know what features of an app you are using.

I dont installed many programs on my phone. I m using only tv remote app.I played a mobile game and it reached 50 degree celsius. But when restarting, it overheats and shuts down. This is so weird

Exactly what settings have you changed regarding clock speed (600 Mhz) and voltage especially?

 

Explain the process of changing the thermal pad in detail, step by step.  Did you remove existing thermal compound material (pasty grey material) and did you use a similar amount, or put more than what was originally there?  It could be there's now too much thermal paste inbetween fhe chip and fhe thermal pad.  I used to have a note 3, it didn't do this.

Maybe there is too much thermal paste between the chip and the thermal pad now. I used to have a note 3 that didn't do this.

I m using Kernel Adiutor for underclocking. 

 

There was tiny thermal pad on the chip. I put more thick and better thermal pad.

@ILI-BIGhat software / system are you running, as in: stock (samsung) android, LineageOS etc?

 

Have you tried a different system?  Is there a reset option for the performance settings?

https://forum.xda-developers.com doesn't seem to have anything for anyrhing past kitkat rom for your device, but I'm sure there is something if you refine the search a few times.

 

Looks like you'll have to compile your own LineageOS rom or something if you want it to work properly, your rom must have really misconfigured thermal throttling.
