When Does Your iPhone Need a New Battery?
Lithium-ion batteries are consumable components that chemically age with every charge cycle. After 500 complete charge cycles (typically 18 to 24 months of daily use), an iPhone battery's capacity drops to around 80%. When this threshold is reached, iOS will display a warning under Settings > Battery > Battery Health: 'Service Recommended'.
Symptoms of a failing cell include sudden shutdowns when battery percentage reads 20% or 30%, noticeably slower app loading times, and a phone that feels hot to the touch during normal web browsing or charging.
Comparing Battery Pricing Across Independent Workshops
For those researching replacement options, independent workshops like i Repair Centre offer a fast, accessible alternative to main-dealer wait times. Every battery replacement includes the battery cell, precision bench fitting, internal adhesive strips, and safety testing.
Replacing a degraded battery extends the usable lifespan of your smartphone by two to three years, avoiding the need to buy an expensive replacement handset.
