I agree with Katana-San. In fact I’d go a step further and request to speak to a store manager and discuss the matter. Tell the manager about your poor customer experience. The manger should take ownership of the situation and make sure things get resolved for you.

They should write up a support ticket and if they can’t resolve escalate the issue. An iPhone should not be overheating and shutting down. Make sure everything is backed up.

Your welcome! I understand your concerns. Your next step to resolving the issue would be to have Apple run diagnostics. Have you had diagnostics performed on your iPhone before?

Hello again ~ Then I suggested …take your iPhone in and get it checked out by Apple again.

~Katana-San~

Hello~ No apologies necessary. Have you force restarted your iPhone?

So…let’s review a bit…you bought your iPhone in October of 2023 and have a battery percentage of 90%…well that’s pretty good when you stop and think about it. Here’s some information…

Heat is a normal part of modern cell phones with multi core processors and multiple graphics processors. There’s no active cooling, like a fan, so heat has to be dissipated through the exterior.

iPhone incorporates internal mechanisms to reduce screen brightness and if necessary throttle the performance of the processors. But heat is normal when gaming, video and battery charging. Have you measured the temperature of the back of your iPhone? Is it shutting down with a warning?

I’m a former Apple Store manager. Talk to a manager and I’m sure he/she will see your experience is vastly different.

Thanks Katana-San, but unfortunately the only option extended by the AppleStore Watford post an assessment was a trade in of the 15 Plus to purchase the latest iPhone 16, with zero additional discount or compensatory sum or gesture of goodwill deducted from the purchase price of the 16!!!

Yes, they tested the iPhone; they noted that it was hot; they said the battery life had depleted significantly and it was purchased from the Watford store in October/November 2023. They didn’t offer to do anything and simply suggested I trade the iPhone in!

Apologies, I think I replied to myself.

Thank you Jeff.

Yes, it occasionally shuts down without a warning. No, I haven’t measured the heat temperature of the iPhone when hot. That’s a step too far for me to establish if my iPhone has a manufacturing defect or is otherwise unfit for its purpose.

As I don’t game or watch videos beyond the few clips a friend might send occasionally, the most content I create are emails and text messages and occasionally I listen to music and take photos.

I simply want a phone that performs the same way all my previous iPhones have performed, namely without “burning” my hand or skin when touched; without the battery erratically dropping it’s charge leaving you uncertain if it’s going to last 2 days, 2 hours or 2 minutes after being charged using the Apple products and with the optimised charging on. I haven’t damaged it; dropped it in water or use non Apple third party accessories on it…and yet…

Yep. At the Apple Store in Watford. Nothing unusual was noted or remarked on. No admissions of fault or indication of user error or misuse. No mention of recommendations. No suggestion to replace the battery. The only suggestion, politely provided and with a smile = trade in your iPhone for the latest model!

Purchased from the Apple Store Watford. I only ever buy my iPhones from Apple so that they’re directly on the hook for any issues I might experience and so I can’t be redirected to my original point of sale and therefore not bounced back and forth between the two until I get worn out with the frustration.

Well thanks to both of you for all your feedback, as now I feel more comfortable that this is less user issue and more like a product issue.

I’ll go back to the Store and if they attempt to fob me off and evade my consumer law options, it’ll be a letter before action and then small claims court.
