4K video heat test with Xperia Z5 hints that its Snapdragon 810 can keep its cool

Granted, the Snapdragon 810 chipset might have still been thermally throttled, and yet Sony knows the issues with Snapdragon 810, and has probably put the phones through extensive testing, and/or applied some thermal management techniques such as better heat dissipation layout and thermal layers inside. Whatever it is, it seems to be working, though we'd have to put the phones through some more stress tests before it can be determined if this latest Snapdragon 810 version inside has overcome its issues with the degrees.
- Display 5.2" 1080 x 1920 pixels
- Camera 23 MP / 5 MP front
- Processor Qualcomm Snapdragon 810, Octa-core, 2000 MHz
- Storage 32 GB + microSDXC
- Battery 2900 mAh(17h 3G talk time)

Good news if one is interested in 4k video recording!

the point is the SD810 in Z5 doesn't overheat. 4K recording is one of the heaviest task you could do on a smartphone, and if it doesn't overheat, you are good to go. way to go Sony, Z5 Premium looks really impressive.

I can't believe the misinformation these so called experts like "B-Tekt" are spreading. For the thousandth time: "NO, CPU DOES NOT RECORD VIDEO" There is a hardware component inside an SoC called as 'codec', which stands for 'code and decode'. That's the component that converts and compresses the frames with RGB values for every pixel into an H.264(or whatever you are using) video, it can also do the opposite and play that onto your device. This is the component that is used for video recording. CPU can be used for video encode and decode though. You can assume CPU as a jack of all trades, master of none type of machine. It will be hugely inefficient and extremely slow compared to a codec in these tasks. The process of doing encoding and decoding on a CPU is called software based encode and decode( well, duh). You can use this option to play some files which your codec doesn't support in MX player or some other versatile player on android. Now, the thing is that SD 810 has one of the best video codec available in the market, if not THE best. Why will it turn off or heat up after just 10 minutes of 4k if a SD 801 or 805 device can do the same. No, this does not prove that SD 810 is a cool chip. That has to do with CPU and GPU which are not at all tested in this 'so scientific' test. Shame on 'B-Tekt' to even call this a news. Spreading misinformation is not cool. These media outlets know nothing and just show how stupid they are.

I guess you haven't heard of the Z3+ overheating problems then..

You don't get it. All phones since 801 till 810 with 4K recording can't get past the 5 minute mark of recording because it requires CPU power therefore it heats up and needs to stop the recording and close the camera app to cool down. Yes, there might be a chip that is used for encoding but the CPU is also there like an assistant. A computer won't function without a CPU. Therefore, even at recording the CPU works hard and heats up. Sony has done a great job in keeping this furnace-hot 810 cool.

Most phones have that 5 minute restriction because of storage issues LOL. I have seen Z3 compact recording 18 minutes of 4k video without heating up. My S6 doesn't even get warm while recording 4k, and irestriction can be removed with root. Please elaborate what job does CPU does alongside. Yes, a computer won't run without a CPU, but that's because you need that thing to run all tasks and to command the codec, but the work done during recording is all done by the memory bus, NAND and codec, with CPU contributing almost nothing. Codec is the reason a pocket camera like RX 100 MK4 can recoed 960 fps video without an octa core- chip, how nokia 808 was able to record 1080p with only single core chip and how a mightly powerful Exynos 5420 can't even play 4k even with it's 8 core power.

A first for Sony phone to really turn me on...'z5 premium ' ..I so want it to produce excellent performance so that it gives the "boastful " Samsung a hard cracking mind thoughts and give us what "many " expected in their next line of flagships esp note 6
