Practical phone and device guides from FixUpPhone: verified specifications, buying considerations, repairability, device care and routes to local or mail-in repair enquiries.
An iPhone 15 that runs hot is usually protecting itself inside Apple’s 0–35 °C operating range. Safe cooling steps, the common causes in order, and when heat with fast drain points to a worn battery — a $99 fix at Apple.
Start with the evidence — the Battery graphs (last 24 hours and last 10 days) and the Battery Health Maximum Capacity percentage — before changing any settings. If the cell itself is worn, Apple’s battery service for this model is $99.
Work the alive-or-dead triage first — signs-of-life checks, a 30-minute charge on a known-good cable, a force restart, and a computer test — before paying for hardware. If the display has failed, Apple’s screen fee is $279, or $29 with AppleCare+.
Work the isolation ladder — cable and adapter, power source, port inspection, the wireless cross-check, settings, liquid and heat checks — to find why an iPhone 15 will not charge. Then compare the repair routes: a $99 Apple battery, Apple’s $549 other-damage tier for port damage, or a FixUp diagnosis quoted after assessment.
Which control is it — Side button, volume buttons or the Ring/Silent switch? The iPhone 15 guide that separates a flipped switch, a pressing case and a software glitch from real button hardware, then prices the repair honestly: no per-button Apple fee, $549 other damage, and a FixUp quote after assessment.
Prove the phone is alive first — call it, plug it in, press the Side button — then force restart, test the bare screen, back up and update. If touch hardware is damaged, Apple’s screen fee is $279, or $29 with AppleCare+.
Why your iPhone 15 sounds muffled, distorted or silent — isolate whether the earpiece or the bottom speaker is failing, run the free checks first, and see why Apple publishes no speaker-only price: speaker damage is assessed inside its $549 “other damage” tier, or $99 with AppleCare+.
Apple publishes no microphone-only fee for the iPhone 15 — microphone damage falls in the $549 “other damage” tier, or $99 with AppleCare+. This guide isolates the fault test by test — Voice Memos against video against calls — so you can tell a blocked opening, a permission or accessory routing from genuine hardware before paying for a repair.
Your iPhone 15 got wet: power it off, keep it off the charger, skip the rice and let it dry in airflow — then get it assessed fast, because liquid damage is priced only after inspection, never from a fixed fee.
