Before you spend a dollar: the lint check
Here's something most repair shops won't lead with: a large share of “broken” iPhone charging ports are actually packed with pocket lint. Shine a light into the port — if the cable doesn't click in as deep as it used to, gently work compacted lint out with a wooden toothpick (never metal). If your phone charges again, you just fixed it for free, and we'd genuinely rather you keep the $89.
When it's really the port
If the port is clean and the phone still won't charge, only charges with the cable held at an angle, isn't recognized by a computer, or the connector feels loose — the port hardware itself has worn out. Thousands of insertions eventually bend and fatigue the tiny internal contacts, and no cable fixes worn contacts.
How we fix it
We replace the charging port assembly with new hardware, then test charging, data connection, and the microphone and speaker functions that share that end of the phone. $89 flat for every model — parts, labor, testing, and tracked return shipping included, repaired within 48 hours of arrival at our Virginia bench.
One honest note that applies to every iPhone repair: iOS may display a “parts and service” notice in Settings for components Apple didn't install or reseat itself — even high-quality ones. It's informational only; every function works fully, and we test everything before shipping back. We'd rather you hear that from us than discover it in Settings.
