I launched a bunch of Antutu Benchmark on my iPhone 7 32Go device and i got some very bad results. The phone should perform at a 170000 level but most of the time the average result is 120000 and sometimes even less like if it was running in low energy mode ( and i checked that's not the case ) I noticed that the top of the Phone near the on/off button gets really hot during the benchmark execution and i found out that if i blow fresh and cold air with a fan on the back of the phone while performing the bench, the result gets higher up to 150000 but never above. I performed a hard reset but the problem remains. It seems that there's a sort of thermal problem that slow down my Iphone. Is something wrong with my phone ? Should i contact Apple ? Below, typical result.
