Charging and getting hot? Samsung might have forgot Ohms law

the heat generated with the charging might be related to the fact that the phone pulls in 2 amps while charging. Look at the charger itself, it says 5Volts and 2Amps. Most cellphones only use 1amp to charge (sgs3, iphone), but with 2amps, it﻿ charges faster, but more heat is generated as more energy is created (directly proportional). I assume there is a resister issue within the phone not handling the current correctly, causing the battery to react weirdly, but that is just my opinion. Same reason not to charge iphone with ipad charger, cause the current is too high and damages the battery. try charging your galaxy s4 with the galaxy s3 charger, or any 5 volt charger with 1 amp current. check to see if overheating while charging﻿ occurs. be aware it will take longer to charge

[Galaxy S 4 Q&A, Help & Troubleshooting] khrystyan27:

I think that all this overheating is a bad quality control. The heatsink on the CPU is not having a strong contact with the IHS.

Perhaps this overheating coming on LTE (4G) network. Now testing couple hours on 2G network and heating is - very low :) or all right.. For next i wil test only on 3G, and will see.

I can confirm heating grow depend of network grade:

On 2G is normaly

On 3G is warm

On 4G is very hot - overheating

[Galaxy S 4 Q&A, Help & Troubleshooting] Aasim-:
I dont think it depends on network.. phone heats up even without sim..

One more thing the me1 update has not solved the heating issue completely but normal phone usage like browsing etc does not cause as much heating as before.
[Galaxy S 4 Q&A, Help & Troubleshooting] khrystyan27:
Ejecting the SIM from the phone doesn't mean that the phone radio chip is off.

Put the phone in airplane mode and test again. :)
[Galaxy S 4 Q&A, Help & Troubleshooting] achyut:
am using 2g and it gets hot as hell. barring the heat, it's a pretty neat phone, I must say.

as for the heat, the back "samsung logo" and the earpiece in front are the areas taking the REAL heat. I cannot even call sometime. sad case. awaiting a better firmware from Samsung.

[Galaxy S 4 Q&A, Help & Troubleshooting] Aasim-:
Are you sure it is a software issue?

I have tried to search everywhere.. but no where it is mentioned that this is a software issue:(
[Galaxy S 4 Q&A, Help & Troubleshooting] khrystyan27:
No, it's not an software issue.

Some of the Galaxy S4 units are facing heating issues because of the bad contact between the heatsink and the processor's IHS. I must say that I am 100% sure of that. One of my acquaintance used the phone for over 4 hours in heavy aplications like video call(Skype), gaming(RR3), about 1-2 hours of music, several photos taken with flash, updated some aplications from Google Play, and so on... and didn't faced any overheating issues.

So I say to all those who have problems with the phone, go to the shop where you made the purchase, and ask for the replace of the unit. It's not normal for a phone to reach temperatures like 40-50 degrees celsius.
[Galaxy S 4 Q&A, Help & Troubleshooting] tclocki:
When I come home from the office, and want to drain my battery (from 60+-5%) I would usually play some games (shadowgun dead zone for example) for hours until it fully drains. I am constantly holding the phone and I don't think its really excessively getting warm. I play it in a room at 25-27 C temperature. By the time I check the temp after I play games with it, it usually is in the 40s. I think that's pretty normal.

How hot would people in here say that their phone is overheating anyway? I think overheating is becoming too subjective here...
[Galaxy S 4 Q&A, Help & Troubleshooting] khrystyan27:
Normally, it's starting to become uncomfortable at 40 degreese Celsius.

But as you said, this thing is subjective. My friend's phone doesn't reach 35 degreese Celsius.

Oh, i forgot the model is i9505.
[Galaxy S 4 Q&A, Help & Troubleshooting] jcolak:
I will tomorow disassemble my S4 i9505 an put thermal paste on processor and see if that will reduce some overheating.

Anyone try that?
[Galaxy S 4 Q&A, Help & Troubleshooting] khrystyan27:
I wouldn't do that if I were you.

Use the warranty. :)

S4 users have to think about underclock :thumbup:

Sent from my GT-I9100
[Galaxy S 4 Q&A, Help & Troubleshooting] :
But that's the thing: consumers that pay premium prices for a premium flagship smartphone should NOT have to be forced into crippling the phone just to get it into a workable state.

On the other hand, I'd proffer underclocking as a means to temporarily deal with serious overhearing issues, at least until those affected get their handset fixed/replaced.

Just a side note to those experiencing significant overheating: try to avoid doing CPU/GPU intensive tasks while the phone is plugged in and charging. It'll probably damage your battery. I've noticed that the worst heat I've experienced has always been from when the phone was charging.

On the i9300 never has heating issues...not happy at all, furthermore when it get hot the battery % drops significantly and then when it cools down it recharge itself! I bought Samsung to avoid issues and .....

I call the service center and for them it is normal reaching 50C, what else can I say:(

Because my killer spec'ed laptop gets hot on the table, and I get annoyed that a killer spec'ed smartphone gets a bit hot under usage because it's on my ear

and btw, my killer spec'ed laptop does not get hot with normal use, but my killer spec'ed smartphone got hot in the initial settings of it

also, I stopped whining because the problem is gone, so you also should stop whining about me whining :D
[Galaxy S 4 Q&A, Help & Troubleshooting] experia1234:
Cannot agree when battery gets coocked under simple tasks shown by the major drop in battery % (when it cools the % goes back up). This is a joke for a flagship smartphone. The Question is, HW or SW related?

Does anybody know how to contact Samsung HQ?
[Galaxy S 4 Q&A, Help & Troubleshooting] Funkym0nkey:
To be honest there is nothing wrong with the phone going to 61C while gaming. If you are worried about the silicon, it can take much higher temps. No need to worry about that. The fact that you can feel the temperature increase is a good thing which shows that it is dissipating heat properly to the outside. You should only start worrying if you are experiencing throttling kicking in.

But yes, the phone getting hotter when you are talking can be and is irritating. That needs to be fixed.

Honestly I am surprised that I am not facing any issue. Temperature here is constant 30°C+ even at night sometimes. But only time my phone gets hot is while playing games. This is I9500. It does not get hot while on phone. Battery temp shows usual 34-35°C after long call and it drops to 32-33 and stays there.

While gaming mine goes to max 48°C. Usually in 44-45°C range. But I have not played heavy 3D games.

’ll go straight to the point… Two apps had been over reaching and over using the processor. These two apps are Samsung Link and Samsung Push Service. The trick is to disable them if uninstalling their update doesn’t work. This can be done by going to SETTINGS > MORE (TAB) >

APPLICATION MANAGER > ALL (TAB). Once you’re there select the respective apps and uninstall the updates or go further and disable them. This is preferably done under the XXUAMDK UPDATE. This should free you to enjoy the wonderful Galaxy S4.

Hi, I also got the same issue with my galaxy s4. It's basically caused because of the extra features Smart pause, air view, air gestures etc enabled in your device. Try to disable them from your notification bar and see the results. It'll also improve the battery performance of your device.

Samsung push is for ChatON app and for updated from Samsung app store (not sure if the app store use it, but I'm sure it's for ChatON).
