I am at my brother's residence and his internet is slow and I can't do anything about it. I wanted to surf fast so I was playing around with settings and find out that the when the low power mode is on the browsing is super fast even with the same Internet connection. My wifi bar keeps dropping from 2 to 1 this is range issue. Internet speed test shows 30/6 DL/UP. Once low power mode is enabled the background app refresh, mail fetch, hey Siri etc...either disabled or reduced that's what the message appears on iPhone. That reduction might free up A9 chip. I could be wrong about this low power mode theory can anyone please verify? I have iPhone 6s 64gb and I am using Safari.
