15.3rc cut-off, 15.3. 1 battery life is good, and the operating temperature is not high.
The improvement of fever performance is very obvious. I used to have a fever after playing with a landlord, but now I don't have a fever after playing for half an hour after upgrading. From iOS 15.3 liters, I feel that the power consumption speed is slower than before, and the fluency is really perfect, so I decided to support the elderly.
Bluetooth and headphones are more stable, updated in the early morning, and there is no interruption on the subway in the morning.
The signal is perfect. There was still a signal when I entered the elevator, and I didn't drop the line after receiving a phone call. The game experience is perfect. I just tried the glory of the king, and the number of team battle frames has been kept at 60. After playing for half an hour, there was no frame drop.
The official version of iOS 15.3. 1 has been upgraded, and its fluency is beyond imagination. IOS 14.8 was not sticky before, but it didn't follow the hand. This time the touch screen is more sensitive and hands-on.
After the update, the battery health value has not changed. Go out with full electricity at 7: 00 in the morning, play games on the subway for 20 minutes, and consume 6% electricity. Before the same operation, the power consumption reached 10%, which really saved electricity.
