Overheating & battery life

Hi XDA,

I got my S4 9500 white a week ago and I have a very mixed review about the phone. First of all the phone is a monster when it comes to performance. I can play dark knight and modern combat 4 even when the power saving mode is on which was not possible in my good old S2:svetius:. the graphics and display is better any mobile device on this earth and I think only note 3 will beat it when its out. the sensors and the features are awesome. Samsung has done a a great job creating a phone which is future proof in terms of performance and features. For people like me who change their device once is 2 yrs its a great phone For a year I hope there will be games and apps which will work on this phone without breaking a sweat. And I am sure Great Devs from XDA will work their magic on this device. I am patient enough to wait as i know that for S2 in the being there was not much development but after 6-7 months things changed for S2. I gave the device to my wife as I know the device will get support for few more years to come like HD2 and I love that phone.

Now not some good things about this phone is heating issue. On my S2 I have experienced heat levels which literally can fry baby's gentle skin:( but still i knew some of the issue was software related and the way thermal design of the hardware. On S4 in last one week I have seen heat up to 54 C which is not good as they should have improved in terms of thermal dispensing of the device and also hardware-software IO should be tested before launching the device. A common consumer should not suffer due to competition for the best mobile phone manufacturer in the bargain. I hope I dont have to send the phone for replacement will be testing it for two-three weeks more on stock only no rooting. The battery life is good. I will post the pictures. The phone charging is the fastest I have seen and that's too contributing the heating issue. I am just waiting for all the xda devs to start working on this device and soon we all can enjoy the best of galaxy S4 which is already a better mobile device:D [/B][/B]

Overheating

I have had the Samsung Galaxy S4 on the Sprint network since week one of release. Noticed overheating as soon as it came home. Battery life while overheating was less than 6 hours. Went back to store, worked with tech dept.; no solution. Went to Samsung reps; no solution. Did my own trial & error and found when I turned off all sync (email, backup, etc.), the phone immediately began to cool. If I leave sync off, it never overheated and battery life is great. Problem is, I want my phone to sync. So while not a fix, the work around for me is to manually sync rather than auto. What I do not know is if it the problem rests on the decline of the Sprint network while they rework the towers to accommodate LTE or if it is inherent to the GS4 processor. Love the phone except for that.

heating while clicking pics

Hi,

Just received my S4 today and have been trying my hands on it.

The phone seems to heat up just after clicking 1 picture from the camera. JUST 1 PIC! Although it cools down quickly but still.. is this normal behavior for any of you? Batt temp- 31.3 C, external thermistor 42C

The upper part of the screen and back usually heats up.

While charging.. 46C (ext thermistor) and 36C (battery)

Browsing net, google play, and facebook app for 30-40 mins.. batt temp- 35C and external thermistor- 52C. While calling, no heat is being experienced. Tried continous calling for about 12 minutes. Idle phone after 5 minutes of usage. battery temp- 31C, external thermistor temp- 30-31C. CPU temperature in idle mode (using system tuner) is around 50C.

Any help would be appreciated guys. Should I send the phone back for replacement?

Overheating by software problem..in my mind

Hi guys,

I am experienced the same problem like you. Almost ended up buying a note 2..

So i did read these 32 pages and tried every single method.

What i did is:

Disabled Chat ON

Disabled ChocoEUKor

Disabled Samsung Link

Disabled Samsung Push service

Also cleared all data from each before ive done that.

Format my memory card on the phone. Took off the battery and the sim card for around 2 mins.

Restart the phone.

I havent done hard reset or any format on the phone.. (i wanted to keep my things..hate to do recovery..)

Finally i have to say it is still overheating. I downloaded modern combat yesterday just to see after a little gaming what will be the result..cost me 6$..

Anyway i could not get more than 51 'C (External thermistor )

When the phone is not in use it shows 36 'C (External thermistor)

Also after 20mins of talk via Viber it was 45-47'C (External thermistor)

How i know it is not as hot as before?? I could talk for that long without burning off the skin of my ears.. Also it was around 51'C when i was just using Viber.

My phone is T-mobile model Sam-919 16Gb LTE version

M919UVUAMDL Baseband

4.2.2 Android version

3.4.0-453951 Kernel.

I hope i can help you guys out or just give a little temporary solution until samsung does something. To be honest it is unacceptable but we can not do anything.. Its a good phone i would like to keep it. If Samsung does not give a firmware or baseband update for that sadly i have to get a note2..

I had overheating problem with my iPhone 5 as well.. I know it has nothing to do with Samsung..but later on it was fixed by an update..

Also if i could lower the temperature with these little changes it supposed to be a software issue.. Hope i could help a little bit. Feel free to ask. I am willing to do anything with the phone to find out what is the cure...

Sorry for my English..i am not a native speaker

Mate

Edit: The wifi was turned on all the time during the test and gaming

If you have mediaserver misbehaving in battery, then try to disable any audio like: touch sound, dialpad sound, lockscreen sound, keyboard sounds, etc... or put it in silent mode.

I have disabled all audio above and now mediaserver is not awake or using cpu.

Install betterbatterystats and go to kernel wakelocks then see AudioOut_2 its the mediaserver, if its stop increasing , then mediaserver stops and overheating is gone.

After Exchange (new phone)

Hi Again,

I drove by a T-mobile shop today where i bought my S4. I stopped and told them the problem. After like 5 mins i got a brand new phone. I thought lets give a shot to another one to see the results. Also i talked to my friend who is working there. She said that if the problem will exist i can bring it back get maybe a new one again. Also contact Samsung and try to get their attention...

So i used as a normal phone. The temperature went up as it used to...

Its like when i was using Viber for texting it was 47'C which still a lot

After that i disabled the Samsung Push and Samsung Link application.

Now i am doing a test. Watching a video now over 35 mins and the temperature is 40-41'C

It is a video what i recorded and it is 15 mins long but i am watching it 3 times in a row..

Also Did a phone call for almost 15mins.. no heating. Compared to that phone which i was called and both of them had the same temperature. The other phone was an iPhone just to mention. I touched both screen and they felt like having the same temperature.

I think the biggest problem is when i am playing a game or using wifi or both. At this time the phone goes up to 52'C..Could not get more of that but i will try to ;))

I also used the navigation for like 12 mins...There is no heating, i mean not a lot just a little which is acceptable.

Did a little web browsing but not too much to give a real result. Anyway it did not get HOT..

Against of these things i will go back to T-mobile tomorrow and ask them what they can do. They told me that after the exchange they will contact Samsung. Lets see how long does it take to get a reply from them. Or just an answer like.."Dear Customers, As soon as we got the solution we will replace your phones so use them crack them and later you will get a new one"

I try my best to get an answer or just anything which gives a little hope.. okay not a little :D

So if i am just using the phone as a normal phone.. No wifi and no games.. IT is behaving well.. So you cannot fry any egg on it..

oFFtopic:

But if you get hungry and you have no gas or a pan..just turn on the wifi and use Viber or play a game then you can cook your egg on the phone..

Although the phone is made for phone calling.. not for Alaska.. noh

Maybe we got the wrong stock meanwhile in Alaska they are complaining about the phone low temperature..

Sorry for make it long.. when i get any news ill leave an other post

Samsung's Reply

All the problems which you have mentioned is the exact same problems that Im facing! I emailed Samsung customer support about this and this is what they had to reply:

"Dear Mashaal Ahmed,

Thank you for contacting Samsung Electronics.

Please find hereafter, our response.

We extremely apologize for inconveniences caused by our product.

As per your enquiry, kindly be informed that Samsung released the improved S/W binary and you can upgrade the latest S/W binary via “Kies” tool or “FOTA” for better status. S/W Upgrading maintains device’s performance and also solves the temperature rising by unique temperature control method of Samsung.

Additionally, when you use applications that require more power or use applications on your device for an extended period of time, you may feel your device is hot to the touch. This is normal and should not affect your device’s lifespan or performance.

And while charging, the device may heat up. This is the same, and if the battery gets hotter than usual, the charger may stop charging. (This information is also explained in User Manual) Samsung observes the International Safety Specifications.

At the same time, Samsung will continue to make our best effort to optimize the software features for user convenience.

Your cooperation is highly appreciated."

Hope you find a better answer than this with T-Mobile :)

Samsung Representative Pitch ;)

Hi Everyone,

I am back..

So the news are...

I was talking to a Samsung representative. We did cache clear hard and soft reset..

1. It will not erase any data from phone.

1. Power the device off (remove and re-insert the battery).

2. Press and hold the Volume Up key, then press and hold the Power key.

3. When the device vibrates; release only the Power key.

4. When the Android recovery menu is displayed; release the Volume Up key.

5. Navigate with the Volume keys to the "wipe cache partitions" option and press the Power key to select.

has NOT helped the phone.. They told me that i can call them on a toll free number to get other solutions..But try it out guys maybe it helps for you.

Okay it was not enough for me.. Waited like 2 hrs and get back into Live Chat again.,,

This guy said almost the same except hard reset.. he was not so good like the first one :)) Anyway.. the phone still overheating

So now the other solution is to use my 600$ worth phone in safe mode and see what happens.. Which means you can only use pre-installed applications..

Safe Mode:

1.Power the device off.

2.Press and hold the Power key for one or two seconds to turn on the device.

3.When the Samsung logo displays, press and hold the Volume down key until the lock screen displays.

Result: If successful, Safe Mode will appear on the device screen in the bottom left corner.

But if i turn off the samsung push and link the temperature goes down by 4-5'C degrees anyway..

So after these things.. I realized it is still having the " S Fry " feature so i went back to t-mobile and got an other replacement.

Still overheating. Going to bring back tomorrow.

Although when im making a normal call it is not overheating. But when i am using any app with internet ex. Viber..The S Fry function turns on.

One interesting thing. I went into Wallmart and met with a guy in the lane while i was waiting.. Guess what.. He had the S4 white from ATT.. HE said that it is not overheating.. Actually he just bought the phone but he was using the internet when i asked him..

Maybe he is a bloody liar.. i wanted to get his phone number to keep in touch :laugh: Sounds crazy i know.. but he got out before me so i could not catch him ;D

That is the story for today. Ill go to T-mobile tomorrow as well :D I think they love me there. So i try to not let you guys down and find the solution..

Not like my ma..she just left me coz a stupid thing which is not even true ;D anyway..im diffrent I'm different ;DD

So i keep posting the news until i will fed up ;)) Hope it helps

heating issue while using camera

My S4 heats upto 47C (external thermistor) when I use camera to click only 5-6 pictures.. Is this the case with you guys here or is it my device only? I know of heating issues in S4 and I am experiencing them too but this particular issue really bothers me as camera is not a heavy application. The phone cools down in 4-5 minutes after closing the camera.

I have an I9505, on stock. I removed the bloatware, I disabled a lot features I have no use for. I keep the power saving mode on, screen on autobrightness.

After I done all this, I am still experiencing heat issues while browsing on 3G.

Something is amiss. I suspect the cores are not powering down after a load, and / or the internet connection is kept up.

I wonder if all the people experiencing problems have their phone rooted.

Guys, Im from Denmark, I bought galaxy s4 a month ago.

When I just got it it's already started facing overheating problem. I sent it to warranty service, and I got the message what they sent my phone to Samsung and they are waiting for Samsung verdict, well finally they told me Im not getting my phone back and I have to contact my mobile operator to get NEW phone.

A week ago I did that, and yesterday I got my new phone.

AND GUESS WHAT?! :)))))))))))))))))))))

Ofcourse it's still fcking overheating!

They send me new phone second time and it's still ****ed up.......

Im gonna give that phone back and get money refund..

Verdict is = these models which was produced now are really ****ed up, and I guess Samsung are making "new colors" ( if you know what I mean) and by this they want to "silently" fix this problem, maybe it's like this ? I guess so, just think how many factory corrupted models around the world, millllllllllllllions of GS4 which are overheating and ofcourse they are not going to fix it in any of "software update" or something. Ir ****ed up, nothing else.

So people, don't waist your time by paying so much money for corrupted product, just give it back and get money refund and Im gonna do it next week. **** this, Samsung really failed.... :(

************ SOLVED AFTER FULL WIPE WITH REPARTITION **********

I have used the rom of Alexyuh, which can be found here:

http://xdaforums.com/showpost.php?p=42287234&postcount=1

Many Thanks!!

===================================================================

Please, if you have GT-I9500, try:

1. Turn off the phone

2. Plug the usb cable to the charger.

3. Wait for the red light comes on

4. Counts up to 5 and pulls the plug

The red led still on?

----

I have both, I9505 and I9500. I9500 overheat many more and if I turn it off, charge the phone and unplug the cable during charging(I use only the stock battery charger), the red led remain on as is when under charging!

Instead, if I unplug the cable from I9505 during charging, the red led immediately go off. Furthermore, the overheat of the I9505 is less.

I have unplugged the cable from the charger 7 minutes ago, but the led red is still on!! I must press and hold the power-on button up to the phone start, but it only seem to start instead it immediately shutdown. Or I must remove the battery! Otherwise, the red led will remain on indefinitely

This behavior happen only if I charge the I9500 when the phone is turned off. :(

I rally had very bad experience with Samsung, I had submitted my phone to service center on 14th of may because it was getting heated a lot. It was showing 58C while charging. But according to Samsung, their so called PROFESSIONAL technical team has not observed any issue and i got the same unit back yesterday. When i plugged in charger after receiving it, it is still heating around 55-56C.

These people are not at all concerned about customer satisfaction..... now i got that fcking same device which i not comfortable at all to use.

They only know what they tested in these 23 days....

Disabled applications issue

Hi again,

So i went back to T-mobile where i bought my phone. Bad news is.. my friend was not working at time.

I had the chance to talk with an idiot there...after an hour discussion I was offered a new phone again.. Okay I told him I dont need the third phone. Ill go back later. Although I was talking to Samsung again. Also I was talking to some expertise..

What I got is.

Firstly I disabled all the applications what I don't use. There is no big change to tell you the truth.

After that we were playing 3d games on the phone and checked the front and back temperature as well. Did not go above 50'c. In my mind it is still a lot. But my geek friend also Samsung said it 8a still acceptable if I play with a 3d game. Also it has no effect on the phone..

SO I did the most of that what I could. . Run 10 apps in the background and playing game at the same time. I got 51`c... at the moment I have to live with it I guess. Anyway ill go to Tmobile tmrrw as well :) ill become a loyal "complainer". I know it seems stupid to disable everything but I am trying to find out it is a software or hardware problem. . Do not really want to get rid of this phone

also I attach 3 pictures so you can see what I disabled. I am trying everything to make it cooler. Ill post again of I got any news

sadly I am getting the same issues of overheating and shorter battery life than expected. Additionally it's constantly running out of memory which is surprising as the Note II ran just about 1GB of overhead while the S4 runs up to 1.8GB. I'm having trouble finding what's hogging the memory.

any suggestions on a great app that will monitor app usage and cpu temperature? I'd like to get this sweet device humming smoothly.

HI guys

Just like Matte56, I paid £500 for my S4 19505 3 weeks ago and it only overheats when I'm using internet over 3G or playing games. It's fine when I'm making calls. I test by calling my other phone and left it for 42 min and the phone is not even warm.

A week after I bought the phone, I took it back and the sales guy was telling me it is normal for a phone of this spec to overheat (since when a sales person tell the truth) so I said I am not happy and want a replacement and he said it will have the same problem. I think about it for a second and took his word for it.

Today I went to a different branch of their store and spoke to a young sales lady who was nice and helpful and she was shocked when I told her that my phone temp was 50 degrees when I was playing a game for 20min. She said my phone must be faulty and ran to the back to get me a replacement which I wasn't expecting to be honest. She also showed me her S4 and said she never had this problem with hers and she use her phone a lot.

So I charged and booted up the replacement one and still the same so I'm going to take it to a samsung service centre sometime next week and see what happens and if anything good, I'll post it here to help others like me.
