The time a phone repair takes depends on what is broken, the phone model, and whether the parts are in stock. Most common repairs are completed the same day, and many take under an hour. Here is what to expect for each type of repair.
Screen replacement
A screen replacement is the most common phone repair. For most iPhone and Samsung Galaxy models, a screen swap takes 30 to 60 minutes. The process involves removing the broken display assembly, transferring any components attached to it (front camera, earpiece speaker, ambient light sensor), installing the new screen, and testing everything.
Some factors add time:
Heavily shattered screens where glass fragments have spread inside the phone require extra cleaning to prevent debris from interfering with the new display's connection
Adhesive removal on phones with waterproof seals (iPhone 7 and later, Samsung Galaxy S7 and later) takes additional time because the adhesive must be softened with heat and carefully separated to avoid damaging the frame or cables beneath it
iPhone screen data transfer on iPhone 12 and newer requires transferring the display serial data from the old screen to the new one using specialized equipment. This preserves True Tone and avoids the non-genuine part warning. It adds about 10 to 15 minutes
Samsung curved screens are more delicate to install because the display wraps around the edges. Alignment must be precise to avoid uneven gaps or adhesive showing through the curved glass
Typical total time: 30 minutes for a straightforward iPhone or flat-screen Android, up to 90 minutes for a curved Samsung or a phone with extensive internal glass debris.
Battery replacement
Battery replacements generally take 20 to 45 minutes. The battery itself swaps quickly, but accessing it is the time-consuming part:
iPhones use pull-tab adhesive strips under the battery. When the tabs work as designed (pull slowly at a low angle), the battery lifts out cleanly in minutes. When the tabs break — which happens often on older phones where the adhesive has hardened — the battery must be loosened with isopropyl alcohol or gentle heat, adding 15 to 20 minutes
Samsung Galaxy phones have batteries secured with strong adhesive and no pull tabs. Heat is applied to soften the glue, then the battery is carefully pried out. The back glass must be removed first on most models, which adds time and requires re-sealing afterward
Google Pixel 7 and newer are designed for easier battery replacement as part of Google's repairability push. Pull tabs and a more accessible layout make these faster
After installation, the phone is powered on and the battery is tested for proper charging, accurate percentage reporting, and normal voltage. Some shops run the phone through a partial charge cycle to verify there are no issues.
Charging port repair
Charging port repairs vary significantly by phone model because of how the port is constructed:
iPhones and many Android phones have the charging port on a separate flex cable (daughter board). Replacing it takes 30 to 60 minutes. The phone is opened, the old flex cable is disconnected and removed, the new one is installed, and the phone is tested for charging, data transfer, and microphone function (the primary microphone is often on the same flex cable)
Some Android phones have the charging port soldered directly to the main logic board. This requires micro-soldering: desoldering the old port under a microscope, cleaning the pads, and soldering a new port. Micro-soldering takes 1 to 2 hours and requires specialized equipment and skill. Not all repair shops offer this service
Before a port replacement, a good repair shop will first try cleaning the existing port. Lint and debris packed into the port from being in pockets is the most common cause of charging problems. A thorough cleaning with a wooden or plastic pick under magnification takes 5 to 10 minutes and resolves the issue about 40 percent of the time, saving you the cost of a part replacement.
Back glass replacement
Phones with glass backs (iPhone 8 and later, Samsung Galaxy S series, Google Pixel) can crack the rear glass in a drop. Replacement time depends heavily on the model:
iPhone 15 and newer: Apple redesigned the back glass to be removable without disassembling the entire phone. Replacement takes 30 to 45 minutes
iPhone 8 through 14: The back glass is bonded to the frame with extremely strong adhesive. On these models, removing the glass without a laser machine is very difficult. Repair shops that use a laser can do it in about an hour. Without a laser, the process involves hours of careful grinding or the use of replacement housings (transferring all internals to a new frame), which can take 2 to 3 hours
Samsung Galaxy: Back glass removal is simpler than older iPhones because Samsung uses less aggressive adhesive. Heat softens it, the glass is pried off, and a new panel is applied. About 30 to 60 minutes
Water damage assessment and repair
Water damage is the most unpredictable repair in terms of time. The initial assessment takes 30 to 60 minutes: the phone is opened, inspected for corrosion, and the liquid contact indicators are checked. What happens next depends on what the technician finds:
Mild exposure with minimal corrosion: Ultrasonic cleaning of the logic board in an isopropyl alcohol bath, drying, and reassembly. Total: 2 to 4 hours including drying time
Moderate corrosion: Board cleaning plus component-level diagnosis to identify any parts damaged by short circuits. Individual components may need micro-soldering replacement. Total: 4 to 24 hours depending on how many components are affected
Severe water damage: Extensive corrosion, multiple component failures. The repair may span multiple days as the technician tests and replaces components one at a time, checking functionality at each step
The most important factor with water damage is time. The sooner the phone reaches a repair shop after exposure, the less corrosion develops. Turning the phone off immediately and not attempting to charge it prevents further short circuits.
Software issues
Software repairs — phones stuck in boot loops, frozen on the Apple logo, or experiencing persistent crashes — typically take 30 minutes to 2 hours:
Factory reset or OS reinstall: 30 to 60 minutes including the download and installation time
Data recovery before reset: If data needs to be extracted from a phone that will not boot normally, this can add 1 to 3 hours depending on the method required
Firmware flash on Android: 20 to 40 minutes. Involves connecting the phone to a computer and flashing the stock firmware using manufacturer tools (Odin for Samsung, Android Flash Tool for Pixel)
What affects repair time
Parts availability
The single biggest factor in repair time is whether the part is in stock. Popular models like recent iPhones and Samsung Galaxy S series usually have parts available immediately. Less common phones — older models, budget brands, or very new releases — may require ordering parts, which adds 1 to 5 business days depending on the supplier.
Phone condition
A phone that has been previously repaired, dropped multiple times, or exposed to water may have stripped screws, damaged internal clips, or corroded connectors. These complications add time because the technician must work more carefully to avoid causing additional damage.
Adhesive curing
Phones with water resistance ratings use adhesive seals around the screen and back glass. After a repair, the new adhesive needs time to cure for the seal to be effective. Some shops use UV-cured adhesive that sets in minutes. Others use pressure-cure adhesive that benefits from several hours of clamp time. The phone is functional immediately, but full water resistance is restored after the adhesive fully cures, usually 24 hours.
