How can I determine if the battery is charging OK?

Firstly, ensure that the device is operating at standard working frequency to prevent excessive power consumption during charging.

Secondly, make sure the device is placed in an open space with no shading during the charging process and avoid charging through glass.

Next, monitor the charging time of the device, which can be compared to the standard charging duration provided HERE. If the device takes significantly longer to charge compared to the standard duration, it may have a charging issue.

For models that are not listed, you can perform a charging comparison by observing multiple devices of the same model with the same configuration charging in a similar environment. Create a voltage trend graph with the Analysis feature on Ecotopia and watch for any significant voltage anomalies in one of the devices. If one device exhibits a noticeable abnormal voltage trend, it may have a charging issue.

Note: When comparing the charging of multiple devices, if the initial voltage values are not consistent, it may result in inconsistent voltage trend patterns. It is recommended to start observing when the devices have relatively consistent initial voltages.
