Poco F9 Ultra vs Xiaomi 18 Fold
Poco F9 Ultra vs Xiaomi 18 Fold, Both phones come from Xiaomi, but they’re built for different people. The Poco F9 Ultra is a regular slab flagship from Xiaomi’s performance sub-brand, aimed at gamers and heavy video watchers who want top hardware without Samsung prices. The Xiaomi 18 Fold is a passport-style foldable for anyone who wants a phone and a small tablet in one device. Poco showed the Ultra on September 1, and Xiaomi launched the Fold in China on September 7, so you can look at both right now.
Poco F9 Ultra vs Xiaomi 18 Fold Specs
On paper, the F9 Ultra has a 6.9-inch 185Hz AMOLED screen, a Snapdragon 8 Elite Gen 5, an 8,050mAh battery, 100W wired and 50W wireless charging, and IP68. The cameras are a 200MP main, a 50MP periscope and a 50MP ultrawide. One hands-on report says the battery should last up to two days of light to moderate use. That’s an estimate, not a lab test. The 18 Fold has a 5.38-inch outer screen and a 7.58-inch inner screen, both LTPO OLED at 1–120Hz and up to 4,000 nits. It runs on Xiaomi’s own 3nm XRING O3 chip, with a 6,000mAh battery and 67W wired and 50W wireless charging. Its cameras are a 200MP main, a 50MP ultrawide and a 50MP 3.5x periscope. One reviewer found the crease barely noticeable but the software less polished than Apple’s. Water resistance is murky. One outlet reports IP58/IP59, while Engadget says Xiaomi shared no rating at its hands-on.
Poco F9 Ultra vs Xiaomi 18 Fold Price
The F9 Ultra costs $799 for 12GB/256GB in global markets, €999 in Europe, and RM3,599 in Malaysia. The 18 Fold starts at 10,999 yuan, about $1,640, and it is China-only for now. So the question this page answers is whether a foldable is worth roughly twice the price. For most people outside China, the choice is already made, because only the Poco is something you can actually buy.
Poco’s cheaper option is the F9 Pro, which starts at $699 with a 6,330mAh battery and a slightly weaker chip. Xiaomi hasn’t announced a global foldable, so international buyers have nothing to pair with the Fold. Outside the Xiaomi family, Samsung’s Galaxy Z Fold 8 competes with the Fold and has a smaller 4,800mAh battery. Honor’s Magic V6 is worth a look too. I’d still keep this pairing, because it shows what one company does at two prices and in two shapes.
The Ultra gives you the fastest chip, a 185Hz screen and a Bose-tuned subwoofer for about half the foldable’s price, which suits gaming and video. It’s heavy at 235g, and Poco’s prices have crept up since the F8 generation. The Fold packs a near-A4 inner screen, a 3.5x telephoto and a 6,000mAh battery into 219g, which helps if you read, multitask or edit on the move. You pay for that with a high price, a China-only release, and software reviewers say is still rough.
Pick the Poco F9 Ultra if you want power, battery life and a price you can live with, in a phone sold in many countries. Pick the Xiaomi 18 Fold if screen size and a telephoto camera matter more, and you’re fine with the cost and the limited release.
