Reports of slow charging on Galaxy S24 after One UI 7 update are likely due to fast charging being turned off by default. Here’s how to fix it

Samsung One UI 7 has raised concerns among Galaxy S24 users regarding slow charging speeds, with some reporting that their devices no longer support fast charging. This issue seems to stem from the “Fast Charging” toggle being switched off by default after installing the One UI 7 Beta update.

The Galaxy S24 series, including the standard S24, which supports 25W charging, and the S24 Plus and S24 Ultra, which can handle up to 45W charging, may experience slower recharge times if this setting is disabled. Thankfully, fixing this issue is simple.

To enable Fast Charging on One UI 7, follow these steps:

1. Open Settings: Launch the “Settings” app on your device.
2. Go to Battery and Device Care: Scroll down and select “Battery and Device Care.”
3. Access Charging Settings: Tap on “Charging Settings.”
4. Enable Fast Charging: Toggle “Fast Charging” to the “On” position for both fast charging options.

Once enabled, your device will charge at the expected fast speeds, significantly reducing charging times.

If the issue persists, consider checking the charging adapter and cable. A faulty or incompatible charger could also be the culprit. For the best results, avoid using third-party products and opt for official Samsung accessories.

As with any beta firmware, it’s important to note that performance issues, including battery drain and charging problems, may occur. It’s recommended to install beta versions on secondary devices until a stable update is available.
