Battery consumption

[brunop2711]

I have a problem of excessive battery consumption with the T-WATCH-Ultra. Considering that I don’t use LoRa, WiFi, or NFC, but only BLE connected to the smartphone—used to detect falls, receive alarm messages via BLE, or send an alarm via the SOS button with custom firmware—why is the battery consumption so high?

If I enable light sleep, when the watch goes into standby, BLE is also turned off. Why does this happen? Is there anything I can do to prevent this?

Here are the tests I've done:

However, there's no example of BLE remaining on and entering light sleep.

I found an example and test case in the IDF:
