SANFIX replaced the battery in an iPhone 14 Pro that had dropped to 77% health with a KC-certified battery, bringing it back to 100% in about 30 minutes including the consultation. With a 180-day warranty on the battery and 30 days on other parts, SANFIX is worth comparing if independent repair shops make you nervous. ## Good to know - **Location**: 7F, BYC Building, 43 Sangmujungang-ro, Seo-gu, Gwangju - **Getting there**: About 447m from Sangmu Station, a 7-minute walk - **Parking**: Building parking available - **Repair time**: About 30 minutes for a battery replacement - **Battery**: KC-certified battery, genuine-part indicator can be checked - **Warranty**: 180 days on the battery, 30 days on other parts - **Services**: iPhone damage repair, iPad and Apple Watch repair *as written by the visitor on Sep 22, 2026* ## Why an iPhone 14 Pro at 77% battery health needed a replacement My iPhone 14 Pro, handed down from my sister, is still going strong! The phone itself is totally fine, but lately the battery has been draining insanely fast ㅠㅠ So I checked the battery health... 77% lol ![iPhone 14 Pro battery health screen showing 77%](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-01-1xvut-899.webp) No wonder it felt like the battery kept vanishing right after I charged it... at this point a replacement was overdue. So I looked hard into where I could get an iPhone battery replaced in Gwangju. Going official felt too pricey, but handing it to just any private shop made me nervous, so I focused on places that use certified batteries and let you check the genuine-part indicator. That's how I ended up at SANFIX in the Sangmu district! It mainly handles iPhone repairs but also does iPad and Apple Watch repair haha. ## Where SANFIX is and where to park: 7 minutes from Sangmu Station, 7th floor of the BYC Building SANFIX is on the 7th floor of the BYC Building at 43 Sangmujung-ang-ro, Seo-gu, Gwangju. It's about 447m, roughly a 7-minute walk from Sangmu Station, and you can park in the building's parking lot. - 📍 SANFIX - Address: 7F, BYC Building, 43 Sangmujung-ang-ro, Seo-gu, Gwangju - Location: About 447m, 7-minute walk from Sangmu Station - Parking: Building parking available I drove there, and I loved that the building had plenty of parking. Finding a parking spot in the Sangmu district is a whole ordeal in itself, so being able to park and head straight up was so convenient haha. ![Exterior of the BYC Building in the Sangmu district, home to SANFIX](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-02-utjm0-1200.webp) ![Parking lot and entrance of the BYC Building](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-03-f8e3d-900.webp) SANFIX is on the 7th floor of the BYC Building.

They even have magazines for us modern humans who'd get bored without our phones lolol. ![Waiting area at SANFIX with magazines](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-07-1lwuq-900.webp) ## The KC-certified battery swap at SANFIX took about 30 minutes First I talked with the owner about my iPhone's condition, and then the battery replacement began. The thing I cared about most when looking into private repair shops was reliable quality, and SANFIX can replace batteries with KC-certified ones!! ![Information sign about KC-certified battery replacement at SANFIX](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-08-1c343-900.webp) They're also running a review event, so joining that lets you get it done a bit cheaper haha. ![Notice about SANFIX's review event](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-09-nezrt-900.webp) ![List of repair services for iPhone, iPad and Apple Watch](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-10-1lh91-m-900.webp) And it's not just batteries — they said they also handle iPhone damage repair as well as iPad and Apple Watch repair. The repair took roughly 30 minutes of waiting. ![Battery replacement work in progress on an iPhone 14 Pro](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-11-kx5g6-900.webp) ![iPhone 14 Pro waiting during repair](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-12-o1o2q-900.webp) ## From 77% to 100%, with the genuine-part indicator confirmed And finally, my iPhone 14 Pro is back! The first thing I checked the moment I got the battery info was the health status lol. The battery that was at 77% is now at 100%!! Yesss ㅠㅠㅠ Once I confirmed the genuine-part indicator too, it really felt like all my battery worries were over. Since I take so many photos going around on blogger campaigns, battery stress has hit me more times than I can count. I'd leave the house with 50%, snap away, and suddenly it's at 2%... Every time that happened I'd have to pull out a heavy portable charger and hook it up, but now I might finally be free of that lol. Goodbye, portable charger...! ![iPhone 14 Pro screen showing 100% battery health after replacement](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-13-17b83-900.webp) ![iPhone settings screen confirming the genuine-part battery indicator](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-14-17rwu-900.webp) ## SANFIX warranty: 180 days on the battery, 30 days on other parts After the replacement was done, they explained things to keep in mind while using the phone haha. One thing that made me feel good about choosing SANFIX was the 180-day warranty after battery replacement. You can't just check a battery right after replacement and call it done — you need to watch how it performs over time. SANFIX guarantees AS for 180 days after replacing with a certified battery, so I felt a lot more at ease even after leaving. For reference, other parts besides the battery come with a 30-day warranty!!! ![SANFIX counter where AS warranty details were explained after the repair](https://img.superchart.com/images/sandfix-gwangju-iphone-battery-replacement/sandfix-gwangju-iphone-battery-replacement-15-m5kx3-900.webp) I started this whole iPhone 14 Pro battery replacement journey shocked by that 77% number lol, and now seeing it at 100% just feels so satisfying, hehe. If the cost of official repair feels like too much and you're looking into a private repair shop instead of the Gwangju iPhone service center, or if you're searching for iPhone repair in Gwangju or iPhone battery replacement in Gwangju, compare SANFIX in the Sangmu district too. As for me, I'm free from the terror of 2% battery and headed home happy haha. ## Where it is - SANFIX (샌픽스) - 7F, BYC Building, 43 Sangmujung-ang-ro, Seo-gu, Gwangju, South Korea - 전남광주통합특별시 서구 상무중앙로 43 BYC빌딩 7층 704-2호 샌픽스 - 35.151003, 126.8478289 - Google Maps: https://www.google.com/maps/search/%EC%83%8C%ED%94%BD%EC%8A%A4/@35.151003,126.8478289,17z --- Superchart · https://superchart.com/en/@gwangju-window-seat/sandfix-gwangju-iphone-battery-replacement/ · https://superchart.com/llms.txt
