Signs Your Battery Needs Replacing
If you're experiencing any of these, it's probably the battery.
Battery drains fast
These models are several years old — their batteries are well past their prime. A new battery restores usable battery life.
Phone shuts down randomly
Shuts down at 20%, 30%, or even 50%? The battery can't deliver enough voltage. A replacement fixes this completely.
Screen lifting from frame
Older iPhones are known for battery swelling. If your screen is lifting, bring it in immediately — a swollen battery is a safety risk.
Performance is sluggish
iPhone slows down to protect aging batteries. After replacement, you'll notice faster performance.
Battery health below 80%
Check in Settings > Battery > Battery Health (iPhone 7 and later). Below 80% means it's degraded.
Phone gets hot
Excessive heat during normal use? A degraded battery works harder and generates more heat. New battery runs cooler.
