POCO C40 review: A 6,000 mAh entry POCO with a JR510 chip — the long-life floor pick.
Three days on a charge, $129 to start.
POCO C40 was a battery-first floor offering — 6,000 mAh in a $129 body with POCO's usual yellow flair. The JR510 chip and 3 GB base were exactly what the price bought; for emerging-market first phones it served as a long-lasting workhorse.
