Does the smart watch what the technical information promise?

Xiaomi himself state on the Produltwebseite a battery runtime of 5 days in the running mode (12 days in the simple clock mode and approximately 35 hours in the GPS + running mode) on. I wanted to know it this time exactly and have logged the battery consumption of the 280mAh battery exactly.

To start the test, the watch naturally had to be loaded to 100%, which was also reached quickly, because the clock was not completely empty. How long will the gadget take to get from 100% empty, I will check at the end of the test, because it has to be completely unloaded. To take one in advance, the Chinese manufacturer gives quite realistic data on battery life. As you can see from the picture, the full charge of 100% was reached at 20:53. We write the 26.8.2017, it is a Saturday.

First sleep over it

8% battery consumption in one night => 92%

Since I fully charged the clock shortly before going to bed, she had to do a few notifications in the first few hours and count almost no steps.

After 9 hours and 5 minutes in bed she just consumed 8% of the battery charge. The measurement took place on Sunday at 7:10.

The first day

Also this day beats with only 11% battery charge => 81%

This day had to be counted to the 5500 steps and some notifications are displayed. Further details about the test environment would be that the ambient temperature is always between 20 and 28 degrees Celsius.

As the first day suggests, the smart gadget is really not a battery rewinder. One reason is certainly the seemingly very power-saving transflective display that we have tested elsewhere. The measurement took place on Sunday at 21:11.

The second night, two hours shorter

This time 7% is spent for one night => 74%

In the next sleep phase, which this time has been somewhat shorter, the clock consumes another 7 percent of battery power. A trend is recognizable, much battery is not needed for sleep measurement. The measurement took place on Monday at 7:05 o'clock.

Day 2 requires 15% of the battery power

Another day with the 4000 steps => 59%

As it turns out, the smartwatch requires about the same amount of electricity during the daytime as it did at night. Incidentally, Bluetooth is permanently activated, the times when no connection is kept within limits, since the smartphone is mostly located near the clock.

5% for the next night and 12% for a long day

After that night 54% and 42% the next evening

An economical night and 9500 steps a day result in a 42% battery charge on the evening of the 3rd day. If you put it that way, the 5 days given by Xiaomi could go out. We will see.

Day 4 - the next 22 hours

This time, a full 23% battery for one night and one day.

Nearly 6500 steps and this time it has pulled 23% power from the battery. So far the day with the highest battery consumption.

The final spurt, will it last?

The goal is clear, 5 days running time.

Is will be a close finish by all means. This morning, the battery level indicator had already dropped to 12%. I was not sure if the 5 days would be reached or if the Zeil would be narrowly missed. Then at 7:41 clock was reached the magic 10% mark, what the smartwatch also known with a discreet vibration. From now on, the backlight is off, which has raised my hopes of reaching the goal of something after 20:53 (reminder: on Saturday at 20:53 the test has started).
The countdown can be seen in the picture. 11:32 am 8%, 2:19 pm 4%, 5:11 pm 3%, 6:12 pm 2%, 8:10 pm 1%. It would now be 43 minutes to do it, but it remains for a last percent battery charge left. Whether that ends? Surprisingly comes after the 1% mark nor the 0% ad, which appeared at 20:52. So one more minute to 0% ... and .. drum roll ... done !!
At 20:58 clock the display turns off, the test is successful, the manufacturer specified a battery life of 5 hours is reached!

How long does a full charge of the Xiaomi Amazfit Pace take?

Now it's time to recharge. I guess so from experience, the loading will take 1 to 1.5 hours. However, I do not use the original charger, which has disappeared somewhere in a drawer with countless others. For the test, I use a Samsung charger with an output of 2.0 amps. It took a little longer than expected. After 2 hours and 10 minutes, the Smartwatch is now fully charged and ready for the next 5 days of continuous use.

What is the direct competition?

Many competing products have significantly shorter transit times.

Finally, here is a brief overview of what it looks like in direct competitors. From experience a lot worse, but let's take a closer look.

SmartWatch 3 SWR50 - buy here directly from Amazon *
The information provided by Sony is a battery life of up to 2 days under normal use. But what does normal usage mean? Unfortunately that is not so easy to find out. I've done a bit of Amazon reviews and there are different statements about the battery life. The information ranges from just one day to the 3 days. So I think the 2 days should be in it, on the 5 days of Xiaomi Amazfit it does not come close. Of course, it has other features, but it lacks, for example, a heart rate sensor, which also consumes a lot of power. Incidentally, the battery of the Sony Smartwatch has a capacity of 420mA.

Samsung Gear S3 - buy here directly from Amazon *
The smart part of Samsung runs according to the manufacturer for up to 4 days with a single charge, the battery has a capacity of 380 mAh. As mentioned earlier, the clocks of course differ in their functions, these are compared in another place. The 4 days would almost come close to the Amazfit of Xiaomi, but if you search a bit on the internet and on Amazon, you will quickly realize that it is not really so easy to load the clock only every 4 days. From just under a day to 2 days runtime is usually the talk, isolated cases speak of 3-4 days.

Motorola Moto 360 Smartwatch - buy here directly from Amazon *
The Moto 360 was one of the first true Android smartwatches, this is about the clock in the second generation. According to the manufacturer, the 300 mAh battery can only last one to one and a half hours, which is quite low. If you go through the tests and reviews in this way, there are also very different details here. Here is the talk of only 6 hours to 2 days.

Huawei Watch 2 with Android Wear 2 - buy here directly from Amaon *
Battery life, according to Huawei to the 2 days with the 420 mAh battery. According to reviews that can be found on various portals, the battery will last until the promised 2 days.
