See this. I just brought up from my old comment.
Hey guys! Ive found a solution for random/auto shutdown problem for bullshitting m5
Ive been trying to solve the matter 3months so far as non technician, had to test few things.
It happens in certain mobile carrier in certain area.
In Australia, With telstra is fine, but with optus and vodafone was the problem when signal goes bad. And the optus and vodafone were in the same network frequency for 3g wcdma 900mhz.
For that 900mhz, even with other phones it gets overheat with bad signal i thought the frequency band is in congestion.
So i decided to turn it off the reception of the 900frequency and it turned out as working.
Ok guys here ya go the solution
Open the Dialpad
Engineermode> in the telephony tap, band mode> tick off wcdma 900 mhz> press set button.
Some said its battery problem but i dont believe them. I read the xda forum and it was irrelevant information.
Again, dont forget not to buy SONY product. Obviously they havent tested phone and did let you buy.
I will be turned back from sony forever from now. Good bye dirty doggy sony!Idiots
####Update for my solution.####
I just got to south korea
My phone turned off
This time was because of 4g lte.
Those who have shutting down problem on lte, follow my instructions and
Tick off lte band 8 aswell.

They officially claimed to be 3rd phone manufacturer following samsung and apple.
And while all the others work great with the same carrier, why only sony is doing the bad job as 3rd grade phone. Even Chinese phones work normally in the same network.
Get out of fantasy for sony plz

bought xperia M5 March 27, 2016. It went off Arpil 8, 2016. I thought it was only lowbat so I charged it for 5 hours when I turn it on, nothing happen, phone is dead. I went to the sonny store, they told me that they have a problem like this on the first batch, but mine is not from first batch. So there is a problem on this kind of unit. Pls sonny don’t sell defective CP.

I have M5 E5606, Rev 2 single sim. I bought a month ago. Never shutdown. Battery life is about 18 hours on stamine mode. It temperature increase but not very heat. I feel the heat down left of the display like in letter "a" "s" of keyboard. I believe is because the mediatek is there.
