Z5 Premium vs Z5 Compact vs Z3 in 4K video recording overheat test (video)
posted by Daniel P. / Nov 16, 2015, 7:37 AM
As you can see in the 4K video recording test with all recent Xperias and their predecessors below, the phones reach very respectable video duration before the usual heat warnings that often happen when you try to record in this ultra high definition pop up. Granted, the Snapdragon 810 chipset might still be getting thermally throttled, and yet Sony knows the issues with Snapdragon 810, so it has probably put the phones through extensive testing, and/or applied thermal management techniques such for better heat dissipation.
Whatever it is, it seems to be working, and, somewhat unsurprisingly, the largest phone in the stable that has the most space for heat dissipation - Sony's Xperia Z5 Premium - manages to last the longest. It recorded 4K video for close to an hour, filling 20 GB before the warning pop up appeared, so you can rest assure that your 4K-on-4K shenanigans with the Z5 Premium can lost longer than the available free space on the phone.
- Display 5.5" 2160 x 3840 pixels

- Processor Qualcomm Snapdragon 810, Octa-core, 2000 MHz
- Storage 32 GB + microSDXC
- Battery 3430 mAh(19.17h 3G talk time)

Yeah but the sad part is that the 'Overheat Test' has become a thing!

Think about how much data the smartphone has to work with on a continuous basis every single second. A 4k frame has 3840x2160 pixels per frame. Each pixel has 4 bytes. So that comes out to 33.18 mb per frame, and with 30 frames per second. That comes out to 995 mb, or just shy of 1 gb of image data per second. But that isn't the taxing part. The processor now has to compress the image data on the fly in order to make the video more manageable. This amount of data would not only tax any processor, but also heat it up. This type of test is not real world.

They should record the video while holding the phone not laying down. We all know that heat will build up because of that position. The recording should last longer when holding the phone properly. Anyways good job Sony!! Now make a good advertisement to your awesome phone!!!

Samsung S6 fail after 20-30 min ( need to look at the phone and restart the 4k video every 5 min... ) LG G4 fail after 40-50 min. So this is far from bad.

Why would you do a test when the phones are laying on the table and not being held on the hand when you are recordedin? Laying it on the table will just let the heat trap.. not a very accurate test..

I am a fan of Sony but I am disappointed with the camera when it comes to Video recording. It automatically close after 5 minutes video recording. The battery overheat that's why the app close. It's not worthy when it comes to video recording.
