Introduction
ChargerLAB had conducted some wireless charging tests before. But only Apple products can support magnetic charging. If phones from other brands want to get a similar charging experience, they have to be equipped with specific accessories. So we take Samsung S23 Ultra as an example to show how to wirelessly charge Android phones using magnetic force.
Product Appearance
We use a magnetic case that can be adapted to the Samsung S23 Ultra.
First, put the case on the phone and the camera is not blocked.
The bottom openings are accurate.
After wearing the phone case, its thickness is about 11 mm (0.43 inches).
The weight of the case is about 43 g (1.52 oz), which is heavier than the regular ones.
After wearing the case, the weight is about 279 g (9.84 oz).
Magnetic Experience
Samsung officially claims that the Galaxy S23 Ultra phone supports 10W wireless charging. And this time, we will use different wireless chargers throughout the test.
The magnetic force of the case is relatively strong, and the phone will not fall when held upside down.
The charging power is about 9.67W, after wearing the case.
When using the second wireless charger, the charging power is about 6.7W.
The charging power is about 6.62W, when using the third wireless charger.
The above three wireless chargers all support Qi. Due to the loss of magnetic charging, the real-time power cannot reach the nominal power.
Full Charging Test
Next, we'll use the Apple MagSafe charger to fully charge the Samsung S23 Ultra.
They will be put into a 25°C (77℉) thermotank throughout the test. Here is the charging curve made by the PC software of KM003C.
The voltage is always around 9V. The charging curve can be divided into two parts. In the first part, the peak power reaches 6.4W for 4 hours and 43 mins. Then, the power drops to almost zero. It takes 4 hours and 56 mins to be fully charged.
We plot it into another chart to see how fast it can be. It can charge the Samsung S23 Ultra to 50% in 2 hours and 26 mins and 80% in 3 hours and 54 mins, and it reaches 100% in 4 hours and 56 mins. The charging speed is very slow.
Temperature Test
We also recorded the temperature during the full charging test. Let’s take a look at the temperature of the phone after 20 mins of charging.
After 20 mins of charging, the maximum temperature of the phone is 36.7 ℃ (98.06 ℉).
Summary of ChargerLAB
This is how to use Android phones to experience magnetic charging. You can get a better wireless charging experience through magnetic accessories. But, the loss of magnetic charging will slow down the charging speed. So, if you are an Android user and want to get a better magnetic wireless charging experience. You need to wait until Android phones supporting Qi2 are released.
