The OnePlus 15 uses a BLPD11 battery, identified from the front label in the selected teardown video. OnePlus lists a 7,300mAh typical equivalent capacity for the phone's Silicon NanoStack battery system. Together, the model code and capacity information provide a useful starting point for battery identification and replacement sourcing. OnePlus official battery information
For repair shops and battery distributors, identifying the original battery is an essential step before choosing a replacement. The BLPD11 code should be checked alongside the phone variant, connector, physical dimensions and electrical specifications.
The manufacturer's advertised capacity and the values printed on a battery label can describe different measurements. Typical capacity, rated capacity and individual cell capacity should therefore be recorded separately when inspecting the original pack.

The battery stores the energy needed to operate the phone's display, processor, cameras, speakers and wireless connections. During use, it supplies power through the phone's power management circuitry. During charging, the charging system manages energy entering the battery.
For a replacement battery, matching capacity alone is insufficient. Correct electrical specifications, connector configuration and physical fit are also necessary for compatibility.
OnePlus advertises up to 31 hours of video playback on its US product page. This manufacturer test figure describes a particular activity under test conditions; it does not mean every user will receive 31 hours of mixed use. OnePlus official endurance claim
Actual runtime depends on screen brightness, network signal, temperature, apps and battery condition. Gaming, extended camera use and weak mobile signals can increase power consumption. As the battery ages, reduced usable capacity can also shorten the time between charges.

These details help a supplier assess compatibility and prepare an accurate quotation. The original battery's capacity or the phone's advertised endurance should not automatically be treated as the performance specification of a replacement product.
