Chinese smartphone vendor Vivo has unveiled the world's lightest foldable smartphone, the X Fold 5 series, as the tech company works hard to beef up its technological strength amid intensified competition.

The X Fold 5 is a follow-up to last year's X Fold 3, which, at 219 grams, was the world's lightest book-style foldable phone. However, the X Fold 5 just about steals this crown by weighing in at 217 grams.

Despite the lightweight design, the X Fold 5 packs a 6,000mAh battery into its frame, a first for a foldable phone according to Vivo.

According to a new report by research firm TechInsights, China's smartphone market achieved strong growth in the first quarter of 2025, with shipments rising 9 percent year-on-year to 68.7 million units. This marks the fifth consecutive quarter of expansion, reflecting sustained market momentum.
