Is hand discomfort common with iPhone 15 Pro Max users?

"Radiation strips" are a scam. iPhones don't emit any kind of ionizing radiation. Putting on such a strip may, however, interfere with the cellular signal, making the phone work hard to connect and causing it to get hotter and drain the battery faster.

You should consult your doctor. You may have some type of repetitive stress injury.

What was your prior iPhone? Are you using a case? Some cases are made of or contain known allergens. The iPhone 15 Pro models have a stainless steel frame. Stainless steel contains nickel, a known allergen. In fact it’s a common allergen that is estimated to affect as many as 20% of the population.

Please contact your primary care physician and get referred to a specialist. You should also contact Apple Support. If you’re in the US please call  1-800-MY-APPLE or outside the US, consult the support articles below.

The last reasonably sized iPhone was the iPhone 4s. Considering that all iPhones after it are undersized tablets, hand pain is likely to occur.

That's a very good point.

I find the non-Max phones to be a reasonable size, but my hands aren't small. I can well imagine someone with small hands trying to use a very large phone one-handed might have a number of issues.

Hello~ Though it’s been suggested already …it’s important that you discuss this issue with your physician. Take care.

Hi, your iPhone 8 Plus was aluminum frame. While nickel is used in aluminum alloys, not nearly the levels of nickel in stainless steel.
