Xiaomi 17 Pro BM6H Battery: 6300mAh Specs & Replacement Guide

The Xiaomi 17 Pro BM6H battery is marked 6300mAh typical and 6150mAh rated. For repair shops, distributors and purchasing teams, the complete assembly model and its electrical label provide a more useful starting point than capacity alone. This guide identifies the battery shown in a real teardown and explains the checks to make before ordering a replacement.

BM6H specifications: read the complete battery label

WekiHome's Xiaomi 17 Pro series teardown directly compares the smaller Xiaomi 17 Pro with the Xiaomi 17 Pro Max. The battery on the right is BM6H for the 17 Pro; the left-hand BM72 belongs to the Pro Max. Keep those handset names and battery models separate when preparing an inquiry.

Specification	BM6H label value
Handset	Xiaomi 17 Pro
Typical capacity	6300mAh
Rated capacity	6150mAh
Nominal voltage	3.76V DC
Charging voltage limit	4.51V DC
Nominal energy	23.13Wh
Typical energy	23.69Wh
Label battery type	Rechargeable Li-ion Polymer Battery

The label values are internally consistent after rounding: 6.150Ah x 3.76V equals 23.124Wh, while 6.300Ah x 3.76V equals 23.688Wh. The higher typical figure and the rated figure should remain separately identified on a quotation. The battery-side 4.51V charge limit is not a USB input-voltage specification.

Battery rear surface, assembly and connection tails

The removed battery shown in the teardown has two visible connection tails. The genuine rear view shows the dark reverse surface while the battery is lifted; the separate dotted adhesive carrier remains beside the chassis. A hand obscures part of the lower edge. The number of tails does not by itself establish the number of cells or their electrical topology. Quote the complete BM6H assembly using its own label rating; do not double 6300mAh because two connections are present.

A close-up elsewhere in the teardown shows an individual cell marking of 6157mAh / 23.26Wh. That observation differs from the complete assembly's 6150mAh / 23.13Wh rating and must not be substituted for it. Cell-production markings and the finished assembly's declared specifications should be recorded separately.

Installed layout: confirm the exact handset

The layout frame shows the BM6H over the chassis during removal, with surrounding components and connection tails visible. It is a view of the Xiaomi17Pro alone. Its BM6H assembly should not be confused with the BM72 assembly used in the larger Pro Max.

Battery life: an independently measured reference

Notebookcheck's Xiaomi 17 Pro review, published October 31, 2025, measured 29 hours 39 minutes of Wi-Fi web browsing in Chrome141 with display brightness adjusted to150cd/m2. Its comparison chart identifies the test as WiFi v1.3. This is a complete-phone test under those conditions, not a guaranteed result for an untested replacement battery. Display settings, software, workload, reception and battery condition affect actual endurance.

Replacement battery checks for repair and wholesale orders

Start with a clear photograph of the customer's original BM6H label, then compare the offered part's connector position, flex-tail shape, dimensions, insulation and complete electrical specification. The shared Xiaomi brand or a similar capacity does not establish cross-model compatibility.

Request a sample specification and confirm the offered product's condition, packaging and order terms before committing to a larger quantity. If documentation or test evidence is required, ask for records that identify the actual offered battery. The photographed original label does not certify a supplier's replacement product.
