Review on Smart bracelet HUAWEI Band 4 Pro, graphite black by Barbara Kurek ᠌

1. It takes about an hour and twenty minutes to charge. 2. Batteries in mixed mode (permanent pairing, 1 lesson per day, 1 walk per day) are enough for about two to three days. 3. The screen, although with light, is still clear and beautiful. 4. I was lucky to buy this bracelet for 2500 instead of 3500, so I am satisfied. Pros: 1. Waterproof 2. Comfortable strap 3. Many workout modes 4. Pulse measurement 5. Smart alarm clock 6. Offline GPS module 7. Physically present blood oxygen sensor 8. AMOLED screen 9. Perfectly pairs with the phone (Honor) 10. You can control the phone's camera and player via Bluetooth Has some cons 1. The pulse measures quite accurately, but only in a certain position on the arm or when you are at rest. During training, if he moves half a centimeter to the side, the readings cease to be accurate at all. There are moments when I am very actively engaged, the heart rate monitor shows 150-160 beats per minute, then the bracelet shifts, and the readings drop to 110 beats. Naturally, it's not my heartbeat that jumps like that. I could not figure out where to fasten the bracelet and how tightly. 2. Many copies with a defective screen, both in 2022 and in China. On mine, after a couple of weeks of use, blue light appeared on the sides of the screen, visible only during the day in the sun. 3. The function of measuring the level of oxygen in the blood was cut out of the box in the 2022 firmware. At the end of April, they added it with an ate, however, I still did not understand why it was and whether it showed exactly. 4. The battery, with constant pairing with the phone, GPS turned on and constant "smart" heart rate measurement, sits down in walking mode by 15-20% per hour. 5. The bracelet is completely waterproof, but you still have to wipe it dry, unless you, of course, like to wear wet things on your wrist. 6. The last few days there have been sudden disconnections from the phone.
