I curse my iPhone 6 plus daily since the last round of iOS updates. It worked fine prior. Now it’s sloooow.

Some bonus features:
When phone boots up it proceeds to download about 50 old texts one after another from like a year ago - I think this finally stopped.
Siri is practically unuseable it’s so slow to respond.
Apps load slow.
Various crashes and freezes
When I open Safari and try to type text in to search, it constantly misses the first letter and then delays the typing of other letters.
It takes forever for the camera app to open, and then if I take a pic, it takes like 6 seconds before the camera actually triggers.
I would gladly have shorter battery life than deal with terrible performance. This is why their explanation makes no sense. And who here know of someone with an iphone that shuts off suddenly. If they do, get a new friggen battery installed!
