DIY case uses kitchen foil layers to cool the Sony Xperia Z3+, performance allegedly improved
As previously reported, the Snapdragon 810 and its overheating woes are causing, at least in some occasions, severe problems on the Sony Xperia Z3+. According to multiple user reports, CPU-intensive apps such as the camera cause the chip to overheat and force-close apps. Even when apps are not forcedly closed, the throttling mechanism impacts the overall performance after prolonged use.
Sony itself acknowledged the problems and promised to launch a software fix, although some believe that this is a hardware problem that can only be solved by imposing even more aggressive throttling mechanisms. Until all of this clears out, XDA-Developers member schecter7 has devised a way of limiting the impact of CPU throttling by layering sheets of aluminum foil on the inside of a regular Xperia Z3+ case.
To determine the efficiency of this DIY case, schecter7 recorded the smartphone's performance and temperature with and without the foil in successive AnTuTu runs. The charts reveal a notable if not an impressive improvement. After 4 AnTuTu runs, performance dropped to 73.40% of the initial horsepower when the smartphone was not in the DIY case, and to 80% afterward. Take a look at the charts:
According to a second XDA member, copper foil works just as well, and this method also reduces temperatures while shooting 4K video.
Even if this method is actually efficient, isn't it a bit offensive to find yourself resorting to a DYI case with aluminum or copper foils just to use your smartphone as it was intended and marketed?
