The Wonder Phone includes a 2850 mAh removable battery with up to 14 days of standby time and support for 14W fast charging. These specs apply to all models: the L'Maaseh-approved Wonder Phone and the Wonder Star.

Charging Your Phone

Every Wonder Phone ships with a charging cable in the box. Plug the cable into the charging port and connect it to a power source. With 14W fast charging supported, the phone charges quickly from low battery.

If the phone does not turn on at all, the battery may be fully drained. Plug it in for at least ten minutes before attempting to power it on.

Battery Life

Under normal use, the Wonder Phone is rated for up to 14 days of standby. Actual battery life varies depending on how much you use calls, music, Waze (on L'Maaseh-approved variants), and other features.

Tips to Extend Battery Life

  • Lower the screen brightness. A dimmer screen draws less power.
  • Keep the flip closed when not in use. The screen turns off when the phone is closed.
  • Reduce volume levels. High speaker volume uses more battery.
  • Keep software up to date. System updates via the System Updater app often include performance and stability improvements that can affect battery efficiency.

The Battery Is Removable

Unlike many modern phones, the Wonder Phone's battery is user-removable. If your battery is no longer holding a charge, you can replace it yourself. A replacement 2850 mAh battery — the same battery that ships with the phone — is available for $25.99 at wondersimple.com.

If your phone is still within its 1-year warranty, a battery issue qualifies as a hardware problem and Wonder will repair or replace the phone at no charge. See the warranty policy for details.

If your phone has been restarting randomly, this can be a sign of a failing battery. Replacing the battery often resolves the issue.
