The POCO C85 is fourth among the best-selling phones on Amazon.it, at 169.90 euro. POCO is Xiaomi's budget brand, and this model has one number that explains its sales on its own: 6,000 mAh.
It is the largest battery in our whole catalogue, inside a body 8 millimetres thick. Which makes this phone unusual to open.

6,000 mAh in an 8-millimetre thickness means one precise thing for whoever repairs it: the cell fills nearly the entire internal surface, and opening this phone means finding it right under your fingers as soon as the back comes off. You do not lever on it, you do not bend it, you do not rush. A bent lithium battery is the one fault that becomes dangerous rather than expensive.
Charging is 33 W and there is 10 W reverse wired charging: this phone can charge another one. That detail matters when the USB-C port fails, because there you lose two functions rather than one — and at the diagnosis stage we test both, not just charging.
The panel is a 6.9-inch IPS LCD at HD+ resolution: a cheap part, as across this class. The fingerprint reader is on the side, so the display can be replaced without losing the unlock. Sealing is IP64: dust and splashes from any direction, but not immersion. And there is a dedicated microSD slot up to 1 TB alongside both SIMs, plus the headphone jack.
