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.

You benchmark test is likely over heating the CPU and it is throttling it down to protect itself. In every day use your CPU would seldom be put through such an ordeal for any length of time.

Sounds like you phone is fine, try to just enjoy it.

What about when your playing a game say Asphalt 8?

If you asphalt 8 hammers the CPU enough it will not only throttle the CPU but also dim the display until it cools off. Most games do not constantly push the CPU to their limits for long periods of time but if pushed the iPhone has no other way to get rid of the heat and has to slow things down.

Apple also uses their own diagnostic software and could care less about what AnTuTu says.

In day to day usage i must admit that everything is running fine and at first sight Asphalt runs well. For sure i should'nt worried about that, but Antutu test kept my attention cause all the reviews on the internet underline how the Iphone 7 performs very well with Antutu. And on mine that's not the case at all, so i'm just looking for an explanation.

Could it be that since you have the 32gb model you have slower write speeds and thats whats driving down the score?

I don't think that there is any kind of relation with the memory writing speed, lower on the 32Go model than the others. I guess it's mainly a matter of CPU heating cause the more i run the test, the more it heats up and the lower the result is. But the fact the result is really bad and that I've never managed to reach the 170000 score ranking ( i'm way far below this level )

Oh sorry I didn't realize you had narrowed it down to the memory of your phone being slower. I just saw a video yesterday showing that the 32gb iPhone had slower internal storage. That said I'm not sure that test actually tests the internal storage speed.
 
In my opinion, bernchmark programs are (for all intent and purposes) meaningless. They are meant for number geeks who rather brag about the results of a test to other geeks, than use the phone in a non-labcoat type manner and enjoy the phone.

If your phone is not functioning properly, try restoring it. If it is functioning properly, forget the testing. You are wasting your time.

I wouldn't worry about it. Sounds like you identified it as a throttling when the load is high, which would be expected during such a benchmark app.

You need to realize that the phone is not going to run at any where that level with normal use. That is confined to the benchmark app pushing it. You should ask yourself: Is the phone running well?

If you phone is lagging all over the place, especially when opening up simple applications like messages or calendars, then I'd be concerned. Then it could be a sign of some inherent issue.

If those applications open up perfectly normal, then your phone is ok.

(PS that is not "very bad performance" from AnTuTu despite it being lower than the 7 average :p)


As Newtons Apple wisely said:

Thank you for all your wise answers guys : i think i feel relieved now. As i've already said everything else runs perfectly fine on my phone. So i'm going to relax, remove Antutu application from my iPhone ;) and enjoy my beloved phone now for real and useful daily tasks :)

Did you just get the phone or have you had it and just decided to run the benchmark? In my opinion there is nothing wrong with running a benchmark to see how your device performs against other devices. Some don't care and thats fun but some do. Me I don't take the result to much to heart but thats easy for me to say because my iPhone 7+ 128GB scored 178759.

This phone i bought is a second hand device, so my inititial purpose was to check out if everything works well. That's why i ran this stressful benchmark. And because it was suppose to return the same result as the Iphone of its kind, to my mind, a big gap in the result or a failed test would revealed something defect. And the fact is that i got very surprised and i still don't have a real raison of such a difference ( as i already said 12000 to 140000 instead of 170000 ).

Was it plugged in when you ran the benchmark?
 
Either the Iphone is plugged or not, same result.

By the way i came accross someone on a french forum who performed the test twice and he said that the result went down from 1700000 to 130000 so i'm not feeling alone anymore ;)

I just tested my 7plus and got this ridiculous score!!

I usually get around 178000 sometimes as low as 160000
