Apple iPhone X vs Xiaomi 15
The Verdict
iPhone X and Xiaomi 15 represent different generations and price points entirely. iPhone X launched in 2017 with an A11 Bionic chip, 3GB RAM, and a 2716 mAh battery, feeling quite dated by modern standards. Xiaomi 15 is a contemporary flagship with Snapdragon 8 Elite, 12GB RAM, and nearly double the battery capacity at 5400 mAh. Display technology heavily favors Xiaomi: 3200 nits versus 625 nits peak brightness, 1-120Hz adaptive refresh versus fixed 60Hz, and a larger 6.36-inch screen. Camera capabilities aren't comparable either, with Xiaomi offering 50MP main and ultrawide sensors plus 8K recording versus iPhone X's dual 12MP setup limited to 4K. Charging speeds differ dramatically: 90W wired and 50W wireless on Xiaomi versus iPhone X's meager 18W wired (requiring separate purchase) and 7.5W wireless. Connectivity also lags on the older phone, lacking 5G entirely and using Wi-Fi 5. At $599 versus $999, Xiaomi delivers substantially more hardware for less money. iPhone X's only advantages are iOS ecosystem loyalty and the premium build feel, but raw specifications and practical performance leave it outmatched across nearly every metric.
