Let me talk about the basic specifications first. Huawei Mate 10 Pro is the largest battery in the five mobile phones, reaching 4000mAh. Nominal charging power 22.5W (5V, 4.5A); followed by Samsung Galaxy S9 +, battery capacity 3500mAh, nominal charging power 10W (5V, 2A); then Samsung Note 8, battery capacity 3300mAh, charging power is also 10W ( 5V, 2A); One plus 5T battery is also 3300mAh, nominal charging power 20W (5V, 4A); Finally, iPhone X, battery capacity 2716mAh, nominal charging power 5W (5V, 1A).
It is worth noting thatiPhone X actually supports fast charging (up to 50% charge in 30 minutes), but it requires an additional charge to buy the charger. So here is still using the standard 5W slow filling test.
All five mobile phones are charged at the same time from 0% battery power. From the test results,After 1 hour and 22 minutes, one plus 5T charge 98%, Huawei Mate 10 Pro charge 94%, Samsung Note 8 charge 79%, Samsung S9 + charge 73%, and iPhone X only charge 47%.
From this point of view, the measured results are basically consistent with the nominal power of the mobile phone and the battery capacity.The Huawei Mate 10 Pro has a maximum charging power of 22.5 W, so the charge is also the highest in the effective time. Followed by a plus 5T, followed by Samsung S9+, Note, iPhone 5's standard 5W slow filling is already too backward.
