Newly purchased phones require proper charging to ensure battery life and longevity. If you’re unsure about how to charge a new phone, follow the steps below to learn the best way to charge your phone.

How long should you charge a newly purchased phone?

According to tech experts, when you first buy a phone and use it for the first time, you should use up the battery until the phone indicates low battery (typically below 20%) before charging. Do not charge the phone immediately after purchasing, and avoid letting the battery drain to 0% during the initial use.

For the first 3 to 5 charging cycles, charge the phone until the battery reaches 100%, then wait an additional 5 minutes before unplugging it. Use the phone until it indicates low battery again before charging. After completing these 5 charging cycles, you can use the phone normally. However, it’s recommended to avoid using the phone while charging, overnight charging, or letting the battery completely drain before charging, as these practices can negatively impact battery lifespan.

Many Vietnamese smartphone users still hold the belief that fully charging and fully discharging the battery is necessary, and they typically charge the phone for a full 8 hours during the first 3 charging cycles. This belief is only applicable to phones that use Nickel batteries with a “memory effect,” while most modern phones use Lithium-ion or Lithium-polymer batteries, and fully charging and discharging the battery can actually harm battery life.

Charging the phone overnight, charging to 100%, and keeping the charger plugged in continuously can have negative effects on the battery. Chemical changes occur within the battery during these practices, resulting in decreased energy storage efficiency.

Tips to extend phone battery life

– Avoid using the phone while charging (playing games, browsing the web, listening to music). This causes the phone to heat up, and prolonged use can lead to overheating and even explosions.

– Charge the phone immediately after it indicates low battery, and avoid letting the battery reach critically low levels or completely drain, as this makes it difficult for the battery to accept energy, resulting in longer charging times.

– Do not let the battery remain empty for extended periods. Prolonged empty battery status can lead to the battery no longer being able to accept a charge.

– Fully charge the battery and remove it from the phone before putting the phone aside for 1-2 weeks of rest.

– Additionally, keep the screen brightness at a moderate level, and set the screen to turn off after 10 to 15 seconds of inactivity. Also, disable background apps such as games, applications, and Wi-Fi…

– Keep the ringtone volume low and vibration light when unnecessary. Also, manually activate Wi-Fi, regularly check the phone and network, as a weak network will expend more energy searching for a signal.
