Nexus 4 running over 100oC safe??

I was messing arround with overclocking and undervolting. after f*****g up my app data with a "bad" undervolt I had a look at overclocking and I get over 100oC and still rising running at 1.7GHz is this normal? I have a fast binned chip

Well the bar only goes up to 100
What does that tell you.
Bring down your oc dude.
The CPU safety threshold is 110.
Meaning if it gets to 110 your phone will shut itself down to prevent damage

Thats all I wanted to know ... But 80+oC is insane for stock!
After undervolting its 75-78oC but that 3x more than my gaming PC!!! (And 2x the GPU temp)

Well what are you doing to cause this heat. On both screenshots you are showing Max load. Max CPU freq at quad core. Of course your CPU is going to be overheating.

if you wanna go mental with O/C, you should go for watercooling or liquid N2

haha, although I did apply thermal compound to my galaxy 5 and it was a lot cooler (it has a metal thing that is conveniently over the CPU

While gaming (or what ever you are doing to get it that high) have someone stand behind the phone with an upside down can of compressed air blowing on the back of the phone. This should help.

Using N⁴ while charging.

A quick question, is it okay to use the Nexus 4 while charging? I was using it, and it charges a bit late but just want to ask if it doesn't harm the battery.

Not that I know of, any phone is okay to be used while charging

But it slows the charge speed if we are using it, ryt?

It depends on what you're doing. If you're playing game then it'll charge slowly. But if you're just texting and browsing then that shouldn't be a problem.

Of course it will slow the charge speed, but that's not dangerous.

you shouldn't have a problem downloading a 1 or 2gig movie within 30 minutes to an hr, it'll drain your battery half way regardless of kernel though.

If you're worried, you should stop pirating or Johnny Law will be on your rear. jkjk
To answer your question, just use it without connecting to the charger. Also, calibrating the battery is not necessary either.

So draining the battery regularly doesn't hurt it?
So in conclusion connecting the charger hurts the battery?

Keeping your battery at 100% all the time (letting your phone plugged into the charger) is literally the worst thing you could possibly do to the battery besides overheating it.
If you want to get the longest lifespan out of the battery, keep it between 40 and 80% and under 40°C (which is why the N4 starts throttling itself at 38°C)

Of course it will. It's a battery. They only have so many charge cycles. You can always buy another. With a little effort the battery can be swapped out.

That's right anyway I just wanted to know the least way I can damage the battery while downloading. ..do u have a suggestion

I can't give you advice on how to make piracy less damaging to your phone. That's against the rules.

I just had my lawyer answer a ~1800 euro claim for some song that had magically found its way into my torrent downloading software. He charged me 208€.
Don't download pirated media..

He never said he was downloading copyrighted material... plenty of legal Ubuntu torrents available and last time I checked that's not piracy

Guys am talking about not damaging my battery not the phone

Anyway thanks all for your answers
So in conclusion
I should download until the battery drops to 40% and then recharge it
2- never leave the device connected all day

Flash a different kernel, then both underclock and undervolt.

Overheating?

What temp would be considered over heating? It gets warm? Is that normal?

Ktoonz kernal

Hello all,
I recently flashed Ktoonz kernels and used the Ktweaker to set it to Performance. When I ran a Quadrant test after rebooting I was more than surprised. The numbers were much lower than a stock kernel. Any one know if I possibly did something wrong? This is the Quadrant score I have and also a shot of the Ktweaker. Thanks.

Do not ever go by quadrant, if the phone feels smoother and faster then it is smoother and faster.
Sent from my SPH-L720 using xda premium

Okay. So what exactly is it that Quadrant is used for then? I always thought it was used to test the speed of the device?

Its a bragging rights thing really, any developer will tell you its completely pointless. Real life usage is what matters. For instance when forcerom came out it had problems with getting 6000 quadrants but was running smooth.
Sent from my SPH-L720 using xda premium

Okay, thanks a lot! Yeah it definitely does feel faster and smoother. Just hoping that with the performance kernel I still get some good battery life.
Sent from my SPH-L720 using xda app-developers app

Yeah if the phone is.fast for you. You shouldn't be concerned about scores.
