Stops Charging Randomly
Wireless Charger Wireless Charger
Severity: MinorWhat Does This Error Mean?
A wireless charger that keeps stopping mid-charge is almost always caused by the phone shifting off the coil alignment, the phone overheating and triggering a thermal pause, or an underpowered wall adapter not sustaining the required wattage.
Affected Models
- Anker Wireless Charger
- Belkin Wireless Charger
- Samsung Wireless Charger
- Mophie Wireless Charger
- Generic Qi Wireless Charger
Common Causes
- Phone shifting slightly off coil alignment — small movements break the connection
- Phone overheating and triggering the thermal protection pause
- Underpowered wall adapter causing voltage drops that interrupt the charger
- Software interrupting wireless charging — some power-saving apps disconnect wireless charging when the screen turns off
- Defective or low-quality charging pad with inconsistent coil output
How to Fix It
-
Use a stand-style wireless charger instead of a flat pad.
Flat pads are highly sensitive to small movements — a table vibration or shifting during the night can break coil alignment and stop charging. A stand charger holds the phone in a fixed position by gravity, making the connection far more stable.
-
Check the phone's temperature during charging.
iPhones and Android phones automatically pause wireless charging when the phone temperature exceeds about 35-38°C. This is a safety feature, not a fault. To reduce heat: remove the case while charging, charge in a cooler location, and avoid using the phone intensively while it is on the wireless pad.
-
Use a higher-quality wall adapter.
Wireless chargers draw power in pulses. A cheap or low-wattage adapter that cannot sustain stable output causes the charger to drop and reacquire the connection repeatedly. Use a wall adapter rated for at least 15W-18W, even if the charger is only 10W — the extra headroom prevents voltage sag.
-
Check for battery-saver or power-management apps interfering.
Some aggressive battery-saving apps on Android kill background processes and can interfere with wireless charging protocols. Temporarily disable any battery optimization apps and test if charging is stable overnight.
Frequently Asked Questions
Why does my wireless charger only stop overnight when I am not watching it?
At night, the phone usually reaches 100% and enters maintenance mode. Many phones drop wireless charging when fully charged, then re-engage when the battery drops a small percentage — this cycle of starting and stopping is normal behaviour, not a fault.
My wireless charger was working fine and suddenly started stopping randomly — what changed?
Sudden-onset random stopping on a previously stable charger is usually caused by the adapter failing, the cable connector getting loose, or a case that has developed a delamination or metal insert. Try a different cable, a different adapter, and remove the case. If none of these help, the charging pad itself may have developed a coil fault.
