That cheap charger from the market stall might work fine for months — until the damage it's quietly doing to your battery starts to show.
Certified chargers and cables are built to deliver power to your phone in a controlled, consistent way. Uncertified or counterfeit ones often skip the safety and quality components that make this possible — even if they look identical on the outside.
Unlike a cracked screen, battery stress from a bad charger doesn't show up immediately. It accumulates quietly, and by the time you notice faster draining or slower charging, months of extra wear may have already happened.
If you've been using an uncertified charger for a while and want to know whether it's affected your battery, the only way to know for certain is to measure the battery's current health rather than guess.
