fter about 1,000 charges, smartphone batteries lose about one-fifth of their charging capacity. A brand ew phone is currently at 78%. What would this phone's battery percentage show after 1,000 charging ycles? (round to the nearest whole number) (1 point)
After 1000 charging cycles, the smartphone battery would lose one-fifth of its charging capacity, which is equal to 20%.
To find the current battery percentage after 1000 charging cycles, we need to subtract 20% of the initial battery percentage (78%) from the initial battery percentage.
20% of 78 is (20/100) * 78 = 0.2 * 78 = 15.6
Therefore, the current battery percentage after 1000 charging cycles would be 78% - 15.6% = 62.4%.
Rounded to the nearest whole number, the phone's battery percentage would show 62%.
