Question 1

How was the Claude vs ChatGPT: Should I upgrade my iPhone 12 with degraded battery and iOS. Join the debate. recommendation reached?

Accepted Answer

You're deciding between a £70 battery replacement on your iPhone 12 and a £799 upgrade to the iPhone 16. Your iPhone 12's battery is already degraded, iOS support ends in roughly a year, and you're facing the real possibility of unexpected shutdowns and noticeably shorter days over the next 18 months. The question isn't really whether the phone still works — it's whether you're willing to spend on a repair that extends a phone's life just as its software becomes obsolete. The recommendation to buy the iPhone 16 held, but ChatGPT's pressure clarified why. The real issue isn't the battery alone — it's the combination of three things happening at once: battery declining faster, software support ending soon, and the phone entering a zone where each pound spent on repairs extends an increasingly obsolete device. A £70 repair feels cheap until you realize you're paying it to maintain a phone that won't receive updates in a year. The cost-per-year over five years actually favors the iPhone 16, which is what made this the right call. This recommendation was reached independently. No brand paid to appear here. The deliberation above is the complete reasoning record.

Question 2

How long until iOS support ends on the iPhone 12 after a battery replacement?

Accepted Answer

Apple typically supports iPhones for 5–6 years after release. The iPhone 12 launched in 2020, so you're likely looking at iOS 19 being the last major version it supports — that's roughly one more year of full updates, maybe two of security patches after that. So a battery replacement buys you a phone that works well but is 2–3 years from meaningful software support. Worth it if budget is tight. Not worth it if you're planning to keep the phone 4–5 years.

Question 3

How much battery degradation do you expect to occur over the next 1–2 years, and how would that impact daily usability compared to the cost of an iPhone 16 now?

Accepted Answer

Apple considers 80% battery health normal after 500 charge cycles — if you're already degraded, you'll likely hit 75-70% within 18 months, which means noticeably shorter days and potential unexpected shutdowns under load. A battery replacement costs ~£70 and buys you a phone that's fully functional but obsolete in software terms by 2026.
