After years on the shop floor, the same handful of iPhone problems come through our door over and over. Some are user mistakes. Some are just lithium-ion getting tired. Most are fixable in a single visit, and almost all of them are at least partly preventable once you know what to watch for.
Here’s the short list of what we see most often, what we do about each one, and small habits that cut your odds of seeing us for the same problem next year.
1. Cracked or shattered screens
Far and away the most common repair we do. The pattern is usually the same — a drop face-down on concrete, a corner hit on tile, a phone that slipped off the dashboard while braking.
There’s a severity gradient that decides how urgent the repair is:
- Glass-only cracks — the top layer is cracked but touch and display still work. The screen is still functional, but the cracks will spread and let dust into the digitizer. This is still a full screen replacement, not a “glass-only” job — modern iPhones bond the glass to the OLED panel, so we swap the whole assembly.
- Display damage — black spots, color bands, dead touch zones, or the screen showing nothing at all. The OLED or LCD underneath is damaged. Same repair, but the urgency is higher because a spreading dead zone can stop you from unlocking your phone.
- Glitching touch — the worst version. A damaged digitizer can register random ghost taps on its own, including wrong passcode entries. After enough failed attempts, iOS locks the phone with the “iPhone is unavailable” message and you can’t get back in without a full restore through a computer. If touch is acting on its own, bring the phone in before it locks itself out.
For most current and recent iPhones we have screens in stock and can do the swap the same day. Pricing depends on the model and which tier you choose — Aftermarket (AM), OLED, or genuine Apple Original. See our iPhone repair pricing page for the full breakdown by model.
Prevention. A tempered glass screen protector catches most direct impacts to the screen itself — that’s all the protector is doing. It won’t save the phone from a hard drop on the corner or back, so pair it with a case that has a raised lip around the screen. We install three protector options at the shop: clear at $15, matte (anti-glare) at $20, and privacy at $25. We’ve seen plenty of phones come in with the protector shattered but the actual screen untouched — that’s the protector doing its job.
2. Battery wearing out
Second most common, and the one customers ask the most questions about. The signs are familiar: the phone dies fast, shuts down at 30%, gets warm during normal use, or feels slower than it did a year ago.
Apple’s official spec depends on which iPhone you have:
- iPhone 14 and earlier: designed for 500 charge cycles to retain 80% capacity
- iPhone 15 and newer: designed for 1,000 charge cycles to retain 80% (Apple doubled the longevity for newer models)
If you’re at or below 80% Maximum Capacity in Settings > Battery > Battery Health & Charging, replacement makes sense. We have battery cells for every iPhone Apple has shipped that’s still in service, and most replacements are same-day.
One specific danger to watch for: a swollen battery. Lithium-ion cells can swell as they fail. If you notice the back glass starting to bulge, the screen lifting at the edges, or the phone sitting unevenly on a flat surface — stop using it and bring it in. A swollen battery pressing on the screen from inside can damage the OLED panel, turning a battery replacement into a battery + screen replacement. Don’t keep using it hoping it’ll settle down — it won’t.
For a fuller breakdown of battery symptoms and how to test before booking a replacement, see our deep-dive on iPhone battery signs.
Prevention. Don’t drain the battery to 0% if you can avoid it — plug in around 20-30%. Don’t keep the phone at 100% all day either; sitting at full charge overnight is one of the worst things for long-term battery life. Optimized Battery Charging (on by default) handles this for you. And keep the phone out of summer heat — dashboards in July are silent battery killers.
3. Charging port issues
Phone only charges if you wiggle the cable. Phone charges sometimes but not others. Phone won’t charge at all. The good news: Lightning and USB-C ports are pretty durable — most of these issues aren’t a failed port, just lint, pocket fuzz, or debris packed deep into the connector.
A quick port clean usually solves it, and it’s the kind of thing we’ll often check for free when you walk in. Two things to avoid that turn a free clean into a paid repair:
- Don’t dig out lint with metal tools. A pin, paperclip, or sharp toothpick can bend or snap the inner contacts. Once those pins go, the whole charging assembly has to be replaced.
- Don’t blast a powerful air compressor into the port. Too much pressure can dislodge or damage the microphone — and on iPhones the mic is part of the same flex assembly as the charging port. Damage one, you replace both.
Canned air can help, but only with short, gentle bursts — full-blast cleaning like you would do on a keyboard is enough pressure to dislodge the mic, same problem as a compressor. Safest path is a soft-bristle brush at home, or just bring it in — port checks are quick and we’ll tell you straight if it’s lint or a real port failure.
4. Water damage
Modern iPhones are water-resistant, not waterproof. The IP rating Apple publishes is for fresh water at limited depth and time — pool chlorine, salt water, soapy water, and toilet water are all harder on the seals. And those seals weaken with age.
When we open up a water-damaged phone, common findings are:
- Corrosion on the logic board or charging port
- Failed display showing lines, color bands, or backlight only
- Speaker or microphone muffled because water is sitting in the grille
- Battery drain accelerated because moisture is shorting low-current paths
What not to do — these are the choices that turn a recoverable phone into a fried logic board:
- Don’t try to power it on. If it’s already off, leave it off. Powering on with internal moisture creates short circuits that can permanently take out the logic board.
- Don’t plug it in to charge. Same reason — water plus voltage equals shorts. This is the single most common way water damage becomes irreversible.
- Rice has limits. Rice can absorb ambient humidity from a sealed container, but it won’t pull standing water out of a sealed phone. Sitting in rice for two days while corrosion does its work inside is how good phones become unrecoverable.
- A hair dryer only dries the outside. The water you can’t see — between the logic board layers, around connectors, under the battery — is what actually kills the phone. Heat from a dryer can also warp components.
What to do: keep it powered off, dry the outside, and bring it in. The faster we can open it up, dry the internals properly, and clean any corrosion before it sets, the better the odds of full recovery.
Prevention. A waterproof phone case is worth it if you’re around pools or boats often. Otherwise just be aware that “water-resistant” has limits — and the older the phone, the less the original seals are doing.
5. Camera lens cracks and focus issues
Drop the phone on its back and you can crack the camera lens cover without touching the front. The phone still takes pictures but every shot looks foggy or has a glare line.
Two flavors of repair:
- Lens cover only — the rear glass over the camera is cracked but the camera module itself is fine. Less expensive, quick repair.
- Camera module — autofocus stopped working, video looks blurry, or the camera app shows a black frame. Usually a drop or water exposure damaged the module itself. More expensive but still very repairable.
We diagnose which one you need before quoting — often it’s just the lens.
Don’t keep forcing a damaged camera to work. A failing module can pull abnormal current and eventually burn out the camera IC on the logic board. At that point the repair jumps from a simple module swap to a board-level repair, which is much more involved. If your camera is acting up, get it looked at sooner rather than later.
Prevention. A case with a raised lip around the camera bump (most quality cases have this) keeps the lens off the surface when you set the phone down. That’s the main thing — don’t set a bare iPhone face-up on a rough table.
How Oasis Savvy handles these repairs
A few things that apply across all five:
- Free diagnostic first. We confirm the actual problem before quoting. Sometimes the “broken charging port” is just lint, and you walk out without paying anything.
- Same-day for in-stock parts. Most current and recent iPhones go home the same day. Older or less common models may take 1-2 days to source the right part.
- Every iPhone model. From iPhone SE up through the latest release.
- Warranty included. Every repair comes with our shop warranty.
- We tell you straight. If a fix isn’t worth it on an older phone, we’ll say so. If it is, we’ll show you the price up front before any work starts.
Stop in for an honest diagnostic
