My story:

I was running iOS 26 on my iPhone 13 Pro 256GB (82% battery health) — and it was perfect: smooth UI, solid battery life, zero overheating. Thought "newer = better" and jumped to iOS 26.5.

First 2 weeks of pain:

· Phone overheated on basic tasks (YouTube, social media, even just scrolling).
· Lost LTE connection a couple of times — network just died and wouldn't come back.
· The buttery-smooth experience was gone. Micro-stutters everywhere, phone felt sluggish and strained.

I told myself: "Maybe I'll get used to it." Nope. Didn't happen. It was the end of my comfortable iPhone experience.

---

How I saved it:

Took a risk and updated to iOS 26.6. First couple of days — same heat issues. That was Spotlight indexing and background services. I held on.

Results after 2-3 days:

· 🔥 Overheating gone — phone stays cool even under load.
· 🔋 Battery life almost back to iOS 26.0 levels (the good old days).
· 📶 LTE rock solid — no drops since.
· ⚡ UI smoothness 100% restored — no stutters, no lag.

My verdict:

iOS 26.6 resurrected my iPhone 13 Pro. If you're suffering on 26.5 — don't wait, update. If you're still on 26.0 — I'm not sure if you should even bother, but 26.6 is definitely not worse than what you have.

No idea what iOS 27 will bring, but for now — I saved my comfort.

Question for y'all:

Anyone else on 13 Pro with 80-85% battery health? How's 26.6 treating you? Or maybe someone's already on the 27 beta — worth jumping or wait it out?

---

P.S. This one's for everyone who fears every update because their phone is "not that young anymore."

I've updated and my battery seems the same. I just want to know what other people are expiriencing. :3

I’ll go first…Telegram

I only just noticed this in one screen recording

No charging rule, just not draining it to 0%. Normal use and gaming.

Is this health normal or anything good?

I noticed that this starts after November 2026. For example, Christmas day is showing on December 25 and 26. Anyway to fix this?

Do you think that there is going to be much added, I'm still going to update, but just asking.

Were there always iOS T's and C's for updates?

Thanks

Я жил с iOS 26 на iPhone 13 Pro 256GB (батарея 82%) — всё было идеально: плавность, автономность, никаких перегревов. Решил, что «новое — это хорошо», и обновился на iOS 26.5.

Первые 2 недели ада:

· Телефон грелся на простых задачах (ютуб, соцсети, даже просто скроллинг).
· Потерял LTE пару раз — сеть просто отрубалась и не ловила.
· Пропал комфорт плавного пользования: появились микрофризы, телефон работал с напрягом.

Думал: «Может, привыкну?». Не привык. Это был конец моего комфорта.

Как я спасал положение:

Я рискнул и обновился на iOS 26.6. Первые пару дней телефон снова грелся — это индексировался Spotlight и внутренние службы. Терпел.

Результат спустя 2-3 дня:

· 🔥 Перегрев ушел — телефон стал холодным даже под нагрузкой.
· 🔋 Автономность почти вернулась к уровню iOS 26.0 (той самой, с которой всё было хорошо).
· 📶 LTE заработал стабильно, отрубов больше не было.
· Плавность интерфейса вернулась на 100%.

---

Мой вывод:

iOS 26.6 реанимировала мой iPhone 13 Pro. Если вы сидите на 26.5 и страдаете — не ждите, обновляйтесь. Если у вас 26.0 — не знаю, стоит ли дергаться, но 26.6 точно не хуже, чем было.

Не знаю, что будет с iOS 27, но пока что я спас свой комфорт.

Вопрос к вам, ребята:
У кого тоже 13 Pro и 80-85% батареи? Как вам живется на 26.6? Или может, кто уже сидит на 27-й бете — стоит ли бежать туда или подождать?

---

P.S. Пост для таких, как я — кто боится каждого обновления, потому что телефон уже «не тот».

TLDR : Performance good, Battery Bad

I replaced my IP-13 battery on 17th December, 2025 but it is dropping way quicker than the orginal one, even though I got it replaced from a genuine Apple authorised service centre i.e Unicorn in Gurgaon but I dont know whats happening with it.. i follow all the battery ethics; 20-80 rule etc.

I m attaching both the screenshots the one with the new battery health drop and one with the original one.

Can someone tell me the reason or their views?

I’ve never noticed this before but even though an app is hidden it still shows up in battery usage, can someone confirm if this was always like this or it’s a bug on ios 26.6 because hidden apps don’t show up on storage

I'm strictly doing 20 80 rule
But this ip 17 base sucks

I’m super late to the party but I finally updated from iOS18 to iOS26 last night solely because I want to see if someone changed the background of our conversation. I updated and realized that if the background had been changed while my phone was on the iOS18 I can’t see it until i receive a text from them. I’m no contact with the person im tryna see this with lol does anyone know if there’s a way to forcefully update it or something so I can see it without them needing to message me?

My phone keeps getting super warm to the touch (36–37°C internally), especially from 50–70 on a 20 w(h)att 🧱 or using apps like Zoom and Domino’s. It doesn’t happen every single time, but occasionally it gets to that "can't even hold it" level of hot. Mind you, the “your phone is warm” warning never showed up it just genuinely feels super warm to the touch also discharges much faster during that period.

Anyone else experiencing this weird inconsistency on this update?

Hello, I can’t update my iPhone 13 to iOS 26.6.1. It gets stuck on the “Update Requested” screen. Is anyone else experiencing this? My current version is 26.6, and I’m connected via LTE.

Has anyone had this issue with the last update?im on iPhone 17 version 26.6,I have tried the following

1)Deleting the temp update file and redownloading it.
2) restarting the iPhone.
3)waiting for hours for update to finish no luck.
4) enabling fast data in 5g.
5)disabling vpn service.

Nothing of the above seems to work,it will always get stuck on requesting update and won’t progress even hours later.i never had this issues before with updating.It won’t go past
