iOS 15 low upload speed

Hello Maged100,

I speedtested my iphone in a wifi to fiber environment : upload was really good ... up to 50 MB. So to me iPhone is ok.

Then, I phoned Apple regarding this issue of low upload speed, but the guy on the phone first seemed not to be much helpfull at all is this matter. Apple said, all background apps shall be switched off, localization shall be off, etc ... I then thought I already did so (but may be not as completly as it would have been necessary...). It then seem nothing improved.

Finnally, by also tring to expend battery usage to maximum between two charges I applied some of following suggestions you can translate on the net if needed :

10 trucs simples pour économiser de la batterie sur un iPhone (francoischarron.com)

14 astuces pour économiser la batterie de votre iPhone (01net.com)

Then I checked again my upload speed and realized it most of the time improved of 3-4 MB which is 50% of my upload speed at home !

I so beleive iOs 15 and many background apps are using 3-4 MB of upload speed for some usages (localization, etc..) you can switch off if not needed. Doing so will free this 3-4 MB of uplaod trafic that is much needed on low and medium upload speed wifi and 3G-4G data connexions.

It would be great if all those apps and iOs using so much of upload flow could be limited to 10-20% of upload speed to keep iPhone available for user/owner... Does anyone have a suggestion to do so ?

Hope this will help you.

Have a good day :)

This may also be of some interest regarding poor 3G-4G upload spped:

But it would be great if all those apps and iOs using so much of upload data flow could be limited to 10-20% of upload data total usage flow on wifi to keep iPhone available for user/owner... Does anyone have a suggestion to do so ?

Thank you

It also seems that some router doesn't work properly if either the firmware is not up to date or no recent firmware solves the problem.

To test if it is a router problem, test you iPhone on another wifi with another router.

For instance Huawei EchoLife HG8245H is a kind of routing-type ONT in the Huawei all-optical access solution that seems to have big problems with iPhones ... Other Huawei ONT has problems too.

Hello Eric,

Went through the steps listed but it doesn't help.

Upload speed is still 50% of available speed whereas download speed is ok.

Does iOS 15 use upload bandwith by itself ?
