soundcore Sleep A10 earbuds detect whether the user has fallen asleep by their movements. If there is little to no movement within half an hour, the earbuds detect that the user has fallen asleep and records it as sleep data. If they often move around while sleeping, it may cause the earbuds to misjudge that they are still awake, so no sleep data will be recorded.

Your sleep report is given using the data gathered from your earbuds. If the sleep data of soundcore Sleep A10 is inaccurate, it could be due to earbuds misinterpreting certain activities as you being asleep or awake. For example, if you're wearing them and sit still for a while or you just leave your earbuds out of the case for a prolonged period of time, it may interpret this as sleep. The soundcore app would then use this data in your sleep report, therefore distorting your sleep curve.
