Summary
Use the included USB-C charger, avoid extreme temperatures, and keep your battery between roughly 20% and 80% for better long-term battery health.
Steps
Remove thick cases and keep the phone out of direct sunlight or beside hot air vents (e.g. hot car vents)
Place the device on a stable, dry, fire resistant surface while charging
Plug Sidephone into the provided USB-C power adapter, or an equivalently rated and certified charger
Unplug at full charge (when convenient), don’t leave the phone plugged in for many hours after it reaches 100%
Considerations
Very cold or very hot environments: Charging may slow down or pause to protect the battery.
Completely drained battery: The screen may stay black for several minutes before showing a charging indicator.
Charging via computer USB port: Charging will be slower than with a wall adapter.
After a software update: The phone may get warmer than usual during the first charge cycle.
Third-party fast chargers: May generate more heat. We recommend using our provided charger or an equivalently certified and performant one.
Longevity: Recharge when the battery drops near ~20% instead of letting it reach 0%
Avoid using heavy apps while charging: If possible, limit intensive use during charging to reduce heat.
Use the original cable if available: If not, use a high-quality, undamaged USB-C cable.
When to Contact Support
Create a support ticket if Sidephone fails to charge after 30 minutes on a wall charger, becomes excessively hot, or shows a battery/temperature warning that does not clear.
What to Collect for Support
Charger brand and output (if known)
Whether you’re using the original cable
