The battery life of the Baby Monitor BM03 depends on the operating mode you choose.
Power-Saving Mode
To achieve the longest battery life, you can enable the power-saving option within the VOX settings.
Please note:
When your device enters power-saving mode, your screen may light up and the signal may be slightly delayed.
By minimizing screen usage, the standby time can be extended up to 120 hours (about 5 days).
