Back in the fall of last year, Xiaomi began to implement a fairly useful item in the HyperOS firmware that displays the number of battery charge cycles (details), but in the latest builds of HyperOS 2.2 there are problems with it.
A new issue in Xiaomi’s HyperOS 2.2 platform has reportedly caused the battery cycle counter to unexpectedly reset on some Xiaomi smartphone models.
On social networks and thematic forums, Xiaomi owners noted a sharp and sudden drop in the number of cycles – sometimes from several dozen to single-digit values.
This has naturally caused confusion, especially among those Xiaomi users who rely on accurate battery health data when servicing or reselling their devices.
It is important to note that these resets do not affect the actual battery performance or health, but they do hide the real battery history of the device.
However, accurate battery charge/discharge cycle data is critical to the used device market. Potential buyers regularly use this information to assess the condition of the device.
