Apple has finally admitted they throttle older iPhones with iOS updates when they release a new model. As the battery degrades over time it’s no longer capable of providing as much power as the CPU needs to draw at peak performance and this can cause unexpected shutdowns so they’ve just been quietly slowing down their phones without disclosing it until now. Probably to encourage you to just buy a new phone for $1000 instead of having the battery replaced for $80.
Anyways if you’re able to replace the battery yourself iFixit sells a kit for $24.99
I just bought a Honeybull battery off amazon ($20 Last I checked) and my phone is running amazing now. It’s a 2.5 year old iPhone 6. It was chugging really bad before but now I’d say it’s back to normal (and no longer shutting off at 30% or when it’s below 60F out). The swap wasn’t all that difficult either.
Duly noted.
Thank you!
