My HP 14-em0xxx recently began losing its charge almost immediately after I unplug it. It can go from fully charged to nearly dead in about five minutes, although it works normally while connected to the charger. I replaced the charger, but that made no difference. HP's UEFI/System Diagnostics reports that the battery is healthy, and a Windows battery report also shows 100% capacity, so I'm not sure whether the battery is actually failing or whether something else is wrong. Could a loose charging port, inaccurate battery calibration, or another hardware problem cause this? Should I replace the battery, and how can I identify the correct replacement for this model before buying one?

The battery is the most likely problem. Diagnostic tools can sometimes report the designed or estimated capacity without catching a battery that collapses under load. If it reaches empty within a few minutes, the cells probably can’t hold usable energy anymore. Check the battery’s label for its exact part number, then match that number when buying a replacement.
The laptop is only around two years old, but that doesn’t rule out a failed battery. Replacing it is usually manageable: shut the laptop down, disconnect the charger, remove the bottom cover, disconnect the battery cable, and install the exact compatible part. Use the battery’s printed part number and the laptop’s full model number rather than relying only on the broad 14-em0xxx series.
A loose or damaged charging port could be worth checking, but it usually causes charging interruptions rather than a battery going from full to empty in minutes. Since a different charger didn’t help and the laptop stays stable while plugged in, the internal battery is the stronger suspect.
Check the battery report’s full-charge capacity and design capacity, not just the percentage shown in Windows. Also see whether the battery percentage drops suddenly in large jumps. If the battery becomes unusually hot, swells, or smells strange while discharging, stop using the laptop and replace or remove it safely.
