How long does the Poco C40 battery actually last?

Thanks to its 6000mAh capacity, the battery reliably lasts 2-3 days with normal use. Even with intensive use, it will last a full long day.

Is the Poco C40 suitable for gaming?

This phone is designed for simpler games (e.g., Candy Crush, Roblox on low settings). Demanding games like PUBG or Genshin Impact will not run smoothly.

Does the device support NFC payments?

This depends on the specific region. Most models sold in the Baltics have NFC, but we recommend checking this in the device settings before purchasing.

Is the Poco C40 waterproof?

The device has an IP52 rating, which means it can withstand light rain and dust, but it should not be submerged in water.

How long does it take to fully charge the battery?

Since the battery is very large and the charging speed is limited to 18W, charging from zero to one hundred takes about 3 hours and 15 minutes.

Can a memory card be used with two SIM cards?

Yes, the Poco C40 has three slots: two for SIM cards and one dedicated slot for a microSD memory card (up to 1TB).
