Zenfone 3 charging slow

[NotCoolBro]

My ZE520KL charges slower now than before, the phone has a quick charge and a fast charge usually i get from 20% to 30% in 4 mins. Now it does from 20% to 23% in 4 mins.. im worried that probably my charger is dying.. i just got the phone 1 month ago. . Any thoughts? (I dont use my phone while charging before and so does now) i treat my phone while charging the same way before

The % charged on phones and tablets is never accurate, its a rough approximation. It could be as simple as a software update has changed the measurement or the battery has slightly lost its peak new performance.
