I am using an iQOO 12 with 16 GB of RAM and 512 GB of internal storage, with no external storage card. I have observed that the device is heating up more than expected and experiencing significant battery drain. Despite achieving an AnTuTu 10 benchmark score of around 1.8 million during multiple tests, the average score for the same variant of the iQOO 12 is around 2.0 million or higher. This discrepancy suggests potential issues affecting the device's performance and battery life. Additionally, I have noted that the camera app frequently runs in the background and consumes a few percentage points of battery even when the device is idle. It is possible that this is not the sole factor affecting the device's performance and battery life.
