iPhone battery degradation is the most common reason people consider replacing their phone — and in most cases, a battery replacement is significantly cheaper than a new iPhone. A 3–4 year old iPhone 13 with 75% battery health performing like a new phone after a $79 battery replacement is a better outcome than a $1,200 upgrade.
Battery health drops because lithium-ion cells degrade with every charge cycle. Apple designs iPhones to maintain 80% capacity at 500 complete charge cycles — after that, degradation accelerates. If you charge your iPhone daily, you'll reach 500 cycles in roughly 16–18 months of continuous use.
iPhone 15 and iPhone 15 Pro battery replacement: Apple introduced a new self-service repair-friendly design on iPhone 15, with a new internal structure. iPhone 15 / 15 Plus battery from $99. iPhone 15 Pro and 15 Pro Max from $109. Same-day replacement in most cases.
iPhone 14 battery replacement: iPhone 14 and 14 Plus use an updated battery secured with adhesive pull tabs. iPhone 14 / 14 Plus from $89. iPhone 14 Pro and 14 Pro Max from $99. The Pro models require more disassembly — same-day in most cases.
iPhone 13 battery replacement: one of the most common battery replacement requests at STS. iPhone 13 and 13 Mini from $79. iPhone 13 Pro and 13 Pro Max from $89. The iPhone 13 generation introduced a higher capacity battery vs the iPhone 12, but the cells still degrade with cycles.
iPhone 12 battery replacement: iPhone 12 Mini, 12, 12 Pro from $79–$89. The iPhone 12 Mini has a notably smaller battery (2,227mAh) which makes the run time impact of degradation particularly noticeable — users with an 12 Mini at 80% health will see significantly reduced use time.
iPhone 11 battery replacement: iPhone 11 from $79. One of the larger iPhone batteries (3,110mAh) but still degrades. iPhone 11 Pro / 11 Pro Max from $89.
iPhone SE battery replacement: SE 2nd and 3rd generation from $79. The SE uses a 1,821mAh battery — the smallest in the current lineup. At 80% health that becomes 1,456mAh, which is very noticeable. SE users often notice battery degradation earlier.
Swollen iPhone battery: a battery that has caused the iPhone back glass to lift, created a gap between the screen and the chassis, or made the screen push out is swollen (lithium electrolyte breakdown producing gas). Replace immediately — don't use wireless charging on a swollen battery. Same-day replacement at STS from $79.
How to check iPhone battery health: Settings → Battery → Battery Health & Charging. "Maximum Capacity" shows your current health as a percentage of original. "Optimised Battery Charging" should be on to slow future degradation. Below 80% = replacement recommended.
