If your phone leaves the house at 100% in the morning and is down to 20% by the afternoon, don't immediately assume the battery is faulty.
Top energy drains include high screen brightness, apps running in the background, GPS, mobile data, and apps that send constant notifications.
First, go into your phone's battery settings and check which apps are using the most power. You can stop unused apps from running in the background.
Setting screen brightness to automatic and only turning on location services when needed can help too.
Another factor is temperature. Using your phone in very hot conditions or playing intensive games while charging can stress the battery.
So before buying a new phone, it's a good idea to check your settings. Sometimes a few small changes can make a big difference during the day.
