I've been loving my new Galaxy Z Fold 5, but recently I noticed something weird. When I plug it in with the official fast charger (45W), the screen flickers intermittently, especially when the device is off or in standby. However, if I switch to slow charging with a regular 15W charger, the flickering stops completely. I've tried rebooting, clearing cache, and even a factory reset, but no luck. The flickering only happens during charging, never when unplugged. I'm worried this might be a hardware issue with the charging circuit or screen, but I haven't found anyone else reporting the same problem online. Has anyone experienced this with foldables or similar devices? Could it be related to power delivery or a software glitch tied to fast charging? Also, is it safe to keep using slow charging as a workaround, or will that damage the battery over time? Any insights or similar experiences would be super helpful!

That flickering during fast charging definitely sounds like it could be a hardware-level issue, especially since it only happens when the device is off or in standby. The fact that it stops with slower charging suggests it might be related to how the charging circuit manages power delivery at higher wattages. I’d be cautious about pushing the fast charger too much if it’s causing visible screen flicker - it could stress the display or power components over time.

Using the 15W charger as a workaround is totally safe for the battery, but obviously slower. If you want to keep the fast charging convenience, I’d recommend getting the phone checked out by Samsung or an authorized service center. Sometimes these foldables have unique power management quirks that only show up under certain conditions, and they might have a firmware update or hardware fix available.

Meanwhile, keep an eye on any other odd behaviors like overheating or battery drain spikes. If you spot those, definitely escalate the issue sooner

That flickering during fast charging sounds like it could be related to the power delivery handshake between the charger and the phone’s screen controller. Since it only happens with the 45W charger and not the 15W one, maybe the higher voltage/current is causing some interference or a subtle hardware glitch.

It’s good you tried a factory reset, so software is less likely the culprit. If you haven’t already, I’d test with another official Samsung 45W charger or cable, just to rule out a faulty charger or cable causing unstable power flow. Also, keep an eye on any firmware updates from Samsung - they sometimes fix weird charging/display bugs.

Using the slower charger as a workaround won’t harm your battery long-term; in fact, slower charging is often gentler on battery health. But if you want fast charging back without flicker, a warranty check or Samsung service visit might be worth it, especially since it’s a new device.

That flickering during fast charging sounds like it could be a power delivery hiccup between the charger and your Fold 5’s display driver, especially since it only happens when the screen is off or in standby. Sometimes, the charging circuit tries to push higher voltage or current that the display’s power management can’t quite stabilize, causing those flickers.

Since you’ve ruled out software with a factory reset, I’d lean toward a hardware or firmware-level compatibility issue. You might want to test with another official Samsung 45W charger or a high-quality third-party charger that supports the same fast charge protocol to see if the problem persists. If it’s consistent across chargers, Samsung support might need to check the device itself.

As for slow charging, it’s perfectly safe and actually gentler on your battery long-term, so using 15W as a workaround won’t harm your battery health. It’s not ideal if you need quick top-ups, but
