OEM vs Aftermarket: An “original” battery means one made (or specified) by the original device manufacturer (OnePlus) or made to their exact specs. Many batteries on the market are replacement / third-party (aftermarket) — always check quality, warranty, seller reputation, and internal cell grade.
Degradation: Over time, all Li-Polymer batteries lose capacity due to charge cycles, heat, and usage patterns. Even an original will degrade after 300–500+ full cycles (or earlier).
Calibration & Usage Advice: After installing a new battery, some recommend calibrating it: fully charge to 100%, keep charging for a while, then use until nearly zero, then charge again uninterrupted. (iFixit mentions doing something similar) iFixit
Safety & Handling: Lithium polymer batteries are sensitive. Avoid puncturing, bending, exposing to high heat, or charging with incompatible / poor-quality chargers.
Non-Removable Design: The OnePlus 7T battery is not user-removable without disassembling the
