Amazing that it doesn't heat.maybe the new set of devices after 2015 August have the problem solved.
If you do some gaming please share with us the max temperature.
You can find it out through cpu z app.
Post the cpu and battery temp.
Most m4 aqua phones heat to a maximum 55-65 celcius.
I've seen many devices.
But some users even witness the heat issue when used lightly.
Here is my opinion about this phone. In one word - AMAZING! I don't play any games, but I don't have any heating problem! When I bought it, I downloaded two updates (about 370mb+190mb), almost 2gb of aplications, and didn't have any heating problem at all, it was a little hotter around the camera, but just little. My previous phone, lumia 520, was much hotter during downloading data. It works great, no restarting at all, it's fast, and has enough memory to install apps (I have currently installed 30apps, all on phone memory), it could be better 16gb memory, but it's OK. Battery is fantastic. I will recommend this phone to anybody, you will not regret if you buy it, the phone is great.

light wieght and handy.
ariana, 27 Oct 2015Hi. I was thinking to buy the M4 but im quite afraid because of the comments that it has huge ... moreBuy xperia C4 or moto G 2015 if you want something other than Samsung.
But sony m4 has a better camera than both the above phones.
Check YouTube videos based on c4 and m4.
Both the devices will receive Marshmallow.
I think c4 is the best choice. Full hd display. 16GB,2GB ram.
And an excellent processor. Plus less heating.
But battery life might be slightly not good.but standby would be great. Will give 2-4 days definitely under light use.
Good phone with a huge heating problem. No effective solution till date.
Hi. I was thinking to buy the M4 but im quite afraid because of the comments that it has huge heating problems and its lag and low on mem. Is it true?
My other choices are Samsung A8, Samsung Galaxy J5, Huawei P8 Lite, Xperia C4, Asus Zenfone 2, Moto G 3. But i want to try Sony because i've been using Samsung for many years.
Which of them is great phone that i could buy for low price, good quality cam and great performance?
Sony had used the 64 bit version of Android 5.02 on m4 aqua. It is buggy and using the 64 bit version should be a reason for heating
I can give proof.
Moto X play uses the same snapdragon 615.but Motorola still uses the 32 bit android 5.1.1 even on such a good device.
I have found that even the moto x play heats but not as much as the m4.
Even the Samsung A8/J7/J5 and moto G 2015 runs on Android 32bit .
Whereas m4 / xiaomi mi4i runs android 64bit.
So basically Samsung and Motorola have avoided 64bit android.
This is the main reason for heating.
I also thinks being sealed from inside due to waterproof rating and using plastic for the phone with maybe no heatpipes aggravated the issue.
Guys this is why sony m4 heats. To overcome the issue sony downclocked the phone thus ruining the game experience.
And antutu scores have become very similar to the moto G 2015.
Don't blame sony. It is qualcomms fault and Android 64bit fault.
I believe sometimes Marshmallow update will solve our problems.
I don't think sony batteries will swell that easily.
Try to always keep the battery temperature below 45 celcius.
I found the reason why our m4 aquas have so many problems compared to other phones.
Anonymous, 25 Sep 2015There is a posibility that the phone Swell for the overheating problem?Please rltell is there battery swelling because of heating?????????????
I newly purchase my M4 aqua. I recognized the Nfc logo won't appear on the upper top side if I activated the Nfc slide touch function but the Nfc field will function to my Bluetooth headset and X tank stereo. Can you please help me for these? I have in my mind updating software or factory resetting could it be. I let you seek for your advice first Sony.
Zablo, 21 Oct 2015I hate this phone, it really heat so much that you worry your phone might melt, beside on that... moreIf the phone is hot, then there are something running in the background that use a lot of battery power. I leave the phone on for more than 48 hrs, still cool and battery still have a lot.
