Phone batteries wear out with every charge cycle. After a couple of years most hold noticeably less charge, and a worn battery can make the phone slow down or switch off without warning. A new battery is usually far cheaper than a new phone.

Does your battery need replacing?
Four signs that the battery, not the phone, is the problem.
Drains fast
The phone will not last the day, or the percentage drops in jumps.
Shuts down early
It switches off with charge still showing, often under load.
Runs hot
It gets hot on the charger or in normal use.
Swollen battery
Back or screen lifting? Stop charging the phone and bring it in. A swollen battery is a safety issue.
