Multiple owners report significant UI lag, slow camera launch, unresponsive Siri, and sluggish messaging from the date of purchase on brand-new units.

“I recently bought a brand new iphone 13 pro max 256 gb from apple authorized reseller. From the date of purchase i have been noticing significant lag in every aspect of user interface. Its as if im still using my old iphone XR.”

vs Marketing: Marketing calls it 'the best iPhone you can buy today' and references a 5-star review for 'superior' performance, but 5 separate user reports describe day-one sluggishness comparable to older budget models.

Camera focus is broken in low-light and flash modes, Cinematic mode is locked to 3x zoom only, and the default camera opens stuck at 2x zoom — all reported as warranty-level defects.

“Default camera mode is always at 2x zoom when opened. Cinematic mode only works at 3x zoom, no video when zoomed out at 1x zoom.”

vs Marketing: Marketing claims 'the biggest camera update ever' and highlights Cinematic mode as a key feature, but users report Cinematic mode is non-functional at standard zoom levels and focus fails entirely in low-light conditions.

A subset of owners report rapid battery drain capping out at roughly 6 hours, with battery health degrading to 87% after just one year of use.

“Battery drains very fast, only lasts maximum 6 hours.”

vs Marketing: Marketing promises 'a big boost in battery life you'll notice every day' and a 5-star review cites 'epic battery life', but at least 2 of 4 battery-related data points describe fast drain and accelerated health degradation.

Users report display defects including black screens with green lines, screen darkening during charging, and hardware failures requiring in-warranty service center replacement.

“iPhone 13 Pro Max has got display issues, I had to get my display changed at the service center because of the same issue. Luckily for me it happened within the warranty period and so replacement was free.”

vs Marketing: Marketing highlights 'a superbright display in a durable design' and ProMotion 120Hz as a flagship feature, but 3 display-related clusters document hardware failures and defects requiring physical replacement.

Photos are described as over-sharpened and over-edited by Apple's processing, with night quality worse than expected and some users rating the Galaxy S21 Ultra as producing better results with manual adjustments.

“I recently got the iphone 13 pro max and the quality of the pictures are horrible!! they are over sharpened and over edited. the quality is even worse at night.”

vs Marketing: Marketing and third-party reviews cite 'superior cameras' as a headline feature, but 2 user data points specifically describe output quality as worse than predecessor devices and inferior to competing Android flagships.
