What‘s your point? It worked fine until I upgraded.
As phone OS's (and apps), just like nearly every piece of sw under the sun, get more are more functionality, we, as users, really need to be able to draw a line somewhere and not upgrade beyond that, as level of performance will eventually render the device unusable.
The problem with that, is that this rule goes against the vendors' interest in customers perpetually upgrading, for whatever reasons (security fixes, new revenue-stream apps, etc). I will salute the first vendor to implement the following policy:
1. Announce going beyond a certain OS version is not advisable for users of product X.
2. Keep providing security patches for lower OS versions several years after that point.
Right now, apple is not really in that category - their OS upgrades are far too aggressive, and the performance impact of their new versions is revealed only post-factum.
Holy shit really? Damn I feel like I've never had an iPhone that actually lasted much more than a full 24 hours, at least with normal use? Maybe if I turned everything off and made it purely a phone... but congrats! That's awesome. I don't remember even my 6+ having that longevity. It's been such a long time though so maybe I'm just forgetting *glares down at backup iPhone 5*
Well, I do use it mainly as a phone, with some light app & wi-fi usage. I always have a tablet and a notebook with me for most heavy app purposes. That said, the SE is apparently the
second-best battery-life iphone.
