1,Our batteries have undergone 100% capacity testing, so under normal circumstances, capacity should not be an issue.

2,It could be due to leakage in the phone itself or app conflicts causing high power consumption, such as prolonged background GPS usage, 5G, or usage in areas with poor signal.

3,High phone temperature leads to faster battery drain. This is a subjective issue often encountered in after-sales processes. It is usually related to individual user experience, emotions, environmental temperature, apps, and changes in performance after battery replacement.

4,Verification method: Comparing usage time after replacing the battery can help identify these issues.
