Do not buy this watch, Mi band 4 was 1000 times better. Hold a charge for 3-4 weeks (offline mode) I watched reviews about band 5 for a long time. They wrote about something that does not hold a charge. Thought the reviews were fake. I bought a watch. Were completely depleted. They did not react for half an hour (connected charging). Then they turned on. While I set them up, the charge dropped from 100% to 60%. I decided that the bluetooth eats the battery like that. But the next day after a 100% charge, offline, in half a day it became 55%. That is, instead of the officially prescribed 10 days, a 100% charge is enough for a day.
