Both Samsung and Apple offer similar warranty coverage, excluding user-caused damage. Samsung provides official support for DIY repairs through iFixit but does not list it as part of the warranty, which is a difference from Apple.

Samsung has an advantage in battery repairs and replacements, likely due to the previous battery issues with the Galaxy Note 7. Samsung’s approach to battery repair includes accounting for excessive battery degradation, whereas Apple has more stringent conditions.

In terms of extended coverage, Apple’s AppleCare+ is more cost-effective, especially for its high-end phones. While SamsungCare+ has lower starting prices for entry-level and mid-range devices, the plans for flagship phones are notably more expensive than AppleCare+ for iPhones. The cost for SamsungCare+ goes up to $329 for the Galaxy Z Fold series and S23 Ultra 1TB variant, whereas AppleCare+ maxes out at $269 for the iPhone 15 Pro and Pro Max.

Overall, the warranty offerings from both companies are quite similar, with Apple having a slight edge due to listing DIY repairs under warranty and providing more affordable premium coverage for its top-tier iPhones.
