Most batteries can’t keep up with your lifestyle. Take gaming as a prime example – this hobby requires plenty of power, but charging while playing often isn’t an option, with most smartphone users experience temperature increases from the high-performance use, interrupting your game.
You’re faced with a lose, lose situation. Even when battery performance is strong, and the charging is quick, phones often overheat easily. If the battery is too small, the battery life is short and doesn’t provide the longevity you’re looking for. Additionally, if the battery is big to allow for longer charge, the phone is too bulky.
