How Long Does a Phone Battery Last?

A typical phone battery usually lasts 2 to 4 years, depending on usage, charging habits, storage conditions, and battery quality. Some batteries fail sooner, especially in older phones that have been heavily used or left discharged for long periods.

Signs you may need a new battery:

	Battery drains much faster than before
	Phone shuts off even when charge remains
	Battery no longer charges fully
	Battery is swollen or physically damaged

Should you replace the battery or replace the phone?

If the phone still works well and the battery is the only problem, replacing the battery is often the smarter and more affordable option. This is especially true for older flip phones, rugged phones, and backup devices that still serve an important purpose.
