Samsung users across the UK, from London apartments to Manchester offices and Glasgow flats, often experience reverse wireless charging issues when their devices are in power-saving mode. Even when the phone’s battery is above the required threshold, Wireless PowerShare may fail to activate or may charge other devices very slowly. AvNexo has collected UK-specific user experiences to provide a comprehensive guide for troubleshooting reverse charging while in power-saving mode.
Samsung power-saving mode limits background processes and reduces power delivery to non-essential functions, including reverse charging. Users in London and Birmingham frequently report that their Galaxy devices will not transfer power to AirPods or other phones while in power-saving mode.
To extend battery life, power-saving mode restricts wireless and high-energy features. Wireless PowerShare may be temporarily disabled or slowed down. UK users in Manchester and Edinburgh found that reverse charging resumed once the mode was turned off.
Power-saving mode also optimizes thermal and battery performance, reducing current to the device’s coils. In cold winter months in Glasgow and Leeds, this can further impact reverse charging performance.
Thick cases or environmental interference (metal surfaces, nearby electronics) can compound power-saving restrictions. Users across London flats reported that removing cases and turning off power-saving mode allowed consistent Wireless PowerShare.
Settings → Battery and Device Care → Battery → Power Mode → Select “Optimised” or “High Performance” instead of power-saving modes.
Even outside of power-saving mode, Samsung requires at least 30% battery to initiate Wireless PowerShare.
Cases or magnetic accessories may reduce coil efficiency. Using a slim case or removing it entirely improves power transfer.
Place the device back-to-back with the target device, ensuring the coils are aligned. Slight adjustments often restore charging performance.
UK users in winter months found that keeping the phone above 10°C prevents additional throttling and improves reverse charging efficiency.
Move away from Wi-Fi routers, smart plugs, or metallic surfaces. Crowded London flats or Manchester offices often amplify interference issues.
If reverse charging fails, a quick restart can reset the Wireless PowerShare protocol and clear temporary software restrictions.
Placing the devices on a solid table rather than soft furniture reduces alignment errors and improves power delivery.
Ensure One UI is up-to-date. Firmware optimizations often improve reverse charging performance, even under power-saving restrictions.
Attempting to reverse charge multiple devices simultaneously can be further limited in power-saving mode. UK users report more reliable results charging one device at a time.
Reverse charging on Samsung devices in the UK can be disrupted by power-saving modes, particularly in London, Manchester, Glasgow, and Birmingham. Real-world experiences confirm that disabling power-saving mode, ensuring proper battery levels, aligning devices, removing thick cases, and maintaining moderate temperatures restores reliable Wireless PowerShare. AvNexo confirms that following these practical steps resolves reverse charging issues in UK environments where energy-saving settings interfere with functionality.
