Your mobile phone can monitor and display the battery

When the battery energy is insufficient, the mobile phone
prompts "Connect charger".

Install the battery into the mobile phone before charging the

Connect the adapter of the travel charger with the charging
slot in the mobile phone. Ensure that the adapter is fully inserted.
