Compatibility Test
Next, let's do the charging compatibility test.
Original Chargers
When using the original charger set to charge the OnePlus 13T, the power is about 9.32V 7.21A 67.15W.
The charging power can reach up to 69.06W.
We summarize the test results into a bar chart. Except for the OnePlus 65W charger, the rest can reach 7A current, and the power is above 67W.
Third-party Chargers
We also used a variety of third-party chargers with the original cable during the test. Let’s take a look at the results.
There are no compatibility issues. Most third-party chargers can reach a voltage of around 9V.
We summarize the test results into a bar chart. The charging power is mainly concentrated in two gears: 17W and 25W. Huawei's 100W charger also supports the UFCS protocol, so it can reach a higher current and a charging power of 34.21W.
Full Charging Test
We use the original charger to fully charge the OnePlus 13T. And put them into a 25°C (77℉) thermotank throughout the test.
The voltage is around 9V at first. The charging curve can be divided into six parts. The peak power is around 67W for the first 38 seconds. Then, the power gradually drops to 53W, 35W, 33W, and 13W in turn. The final part begins at 46 minutes, and the power drops to 5V. It takes 1 hour and 1 minute to be fully charged.
We also turn it into another curve. It reaches 50% in 21 minutes. And it can reach 80% in 35 minutes, 100% in 1 hour and 1 minute.
Temperature Test
We also recorded the highest temperature on the front and back after charging for 10 minutes, 20 minutes, and 30 minutes.
10 minutes Charging
After 10 minutes, the maximum temperature on the front is 37.9℃ (100.22 ℉).
The back is 38.8℃ (101.84 ℉).
20 minutes Charging
After 20 minutes, the maximum temperature on the front is 38.2℃ (100.76 ℉).
The back is 38.6℃ (101.48 ℉).
30 minutes Charging
After 30 minutes, the maximum temperature on the front is 38.3℃ (100.94 ℉).
The back is 39.1℃ (102.38 ℉).
We also turn it into a bar chart. During charging for 30 minutes, the temperature is between 37.9 and 39.1°C. Considering the charging power, the OnePlus 13T maintains a stable charging rate between 33W and 35W within the first 30 minutes, indicating effective thermal management and good temperature control during charging.
