iPhone 16 Pro battery drains fast, overheats and freezes even in normal use (Turkish owner, TR market)
A Turkish owner who bought at Media Markt reports fast battery drain from day one, then overheating and freezing after ~4 months; the authorized service returned it with 'no problem' and the complaints persist. A second sikayetvar page aggregates 8 complaints of the same fast-drain/overheating pattern.
What to check. Buyer should expect battery life to fall short of a full day and possible overheating/freezing; if it happens, the warranty service may not fix it, so document the issue early.
Green/pink/white lines on iPhone screens after iOS 18 — regulator investigation, repair costs not covered
India's consumer regulator (CCPA) opened a detailed investigation into complaints that iOS 18 caused green/pink/white lines on iPhone screens and microphone failures, with users charged for display replacement because Apple's warranty does not cover software. The same page notes one iPhone 16 Pro user whose front microphone stopped after iOS 18.2.1.
What to check. A display-line fault after an iOS update may be treated as out-of-warranty, so buyers should keep evidence and push back on repair charges.
Severe repeatable battery drain and heating on iPhone 16 Pro (iOS beta)
An Apple developer-forum user documents severe battery drain (77 points in 4h23) and warmth on an iPhone 16 Pro, with no hardware failure found in sysdiagnose — pointing to software/background activity rather than a defective battery.
What to check. Severe drain on a 16 Pro is often software-related (beta or background activity) rather than a battery defect; check Battery Health and background app activity before assuming hardware failure.
iPhone 16 Pro touchscreen intermittently unresponsive near edges and camera control button
A Taiwanese retailer's compiled owner complaints list touchscreen unresponsiveness near the screen edges and camera-control button on the 16 Pro, attributed to iOS 18's accidental-touch algorithm and the narrow bezel; Apple reportedly shipped an iOS update to address it.
What to check. If touch input drops out near edges, update iOS first before assuming hardware failure; a screen protector can also trigger it.
iPhone 16 series runs hot after brief use (photos, social apps)
The same compiled-owner source lists overheating after taking a few photos or scrolling social apps across the iPhone 16 series, attributed to iOS 18 compatibility not yet optimized. This is reported for the series rather than the Pro specifically.
What to check. Early overheating is commonly iOS 18 software-related and may settle after updates; if it persists, treat it as a service issue.
These reports come from the pages linked under each item: owner forums, repair guides and workshops. They are not a diagnosis of any one unit, and a careful check of the one you are buying still applies.
