may be affected by the original note 7, the last two years Samsung flag machine battery capacity and charging speed has been stalled, rather conservative. Will this year’s new flagship S9 be changed?
A few days ago, the charge head network to Samsung S9 carried out a detailed charging test. The results found that S9 still stay in the QC 2.0 standard, although also considered as fast charging, but still only 10W charge power (full charge voltage of 9V, but the maximum current less than 1.2A), and the current mainstream 18W fast or even 22.5W fast-charging, there are large gaps.
From the charging curve, one hours before charging, the current is on the rise, the process of cell phone charging power to maintain around 10W, belong to the “fast charging.” After one hour, the charge current decreases with the increase of the cell phone charge until the charging ends.
Because the cell phone battery capacity is only 3000mAh, the final charging time is not too long, full of spending 2 hours, than the iphone or faster.
temperature, room temperature 24 ℃ environment, the maximum temperature of the phone after the cover of 1 hours after charging, about 36 ℃, which is the maximum charging power point of time. The initial temperature of the mobile phone is about 28 ℃, the end charge is 29 ℃, the maximum temperature rise is about 8 ℃.
