How is the battery life for the Iphone 8 plus users so far with iOS11?
Seeing that iOS11 on the older phones is causing a lot of battery drain, just wanted to see if this is some special sauce that Apple cooked for iPhones older than iPhone8?
It's not the conspiracy the way you suggested (baking something into the OS), but it kinda is. The new OSes are very processor and graphics and RAM intense, so the older processors will struggle and hence "drain".
I have a 5S - not even thinking of 11. GOt an SE - went to 11 and the battery life was halved, went back to 10.3.3, battery life back to the same. But the iphone 7 has no problems (says my wife, not sure how true, but it should be fine, because the processor is dan fast)
Since this is an impression thread, I really really really envy the A11 Bionic processor. It is basically faster than my brand new i7 7500U laptop (if Geekbench is anything to go by). Can somebody figure out a way to install this chip onto my laptop? No I don't have a use for that speed on a phone.
I don't think there is much coincidence that they release the new OS just as the new models come out. So people upgrade to the new OS and get fed up with the new slowness, and decide that it is a good time to upgrade, as they will also be benefiting from the new features. I have done this myself.
