How Much Time Is Required to Fully Charge a Samsung J7 Prime?

The Samsung J7 Prime, a popular Android smartphone, typically takes around 2 to 3 hours to fully charge from 0 to 100 using its standard charger. However, the actual charging duration can vary based on several factors such as the charger’s wattage, the condition of the battery, and whether the phone is in use during charging.

Differentiating Charging Times

The charging duration for the Samsung J7 Prime can be influenced by the type of charger used. For instance, using a Samsung charger that outputs 5V 1.55A will usually take up to 2 hours to fully charge the phone. This standard charger, which comes with the device, ensures a stable and safe charging process.

Note that Samsung J7 Prime does not support very fast charging technologies, often found in flagship devices. This means the charging process will generally be slower compared to devices that support higher charging speeds.

Charging Time Variations

Real-life experiences and testing indicate that the J7 Prime can take approximately 2 to 2 hours and 15 minutes to charge fully, depending on the charger’s output and the additional load on the phone. For instance, using a power bank that outputs DC 5V 2.1A reduces the charging time to around 1 and a half hours. This is because the rate of charging tends to slow down after reaching 80%, which makes it difficult to calculate the total charging time linearly.

Theoretical vs. Practical Charging Times

The theoretical charging time for the Samsung J7 Prime is based on the calculation of its 3300 mAh battery and its 2A charger. By dividing the battery capacity (3300 mAh) by the charging current (2A), we get 1.65 hours, or approximately 1 hour and 39 minutes. However, practical experience shows that due to losses and other factors, it typically takes around 1 hour and 45 minutes to fully charge the phone.

Practically, in real-life scenarios, it often takes more than 1 hour and 55 minutes. This is due to inefficiencies in the charging process and the inherent losses that occur during charging. Additionally, if the phone is in active use during charging, this can extend the charging time.

Alternative Device Recommendations

For users who prioritize camera quality, the Samsung J7 Prime may not be the most ideal choice. In such cases, more budget-friendly alternatives like the Redmi Note 4, which offers a combination of performance and affordability, might be a better option. For those seeking a more mid-range experience, the Moto G5 Plus or even the Honor 8 could be considered. Each of these devices may offer faster charging capabilities, making them more suitable for users who demand quick charging.

Overall, the Samsung J7 Prime is a well-balanced device with a decent battery life, suitable for everyday use. However, users should be prepared for a charging time of approximately 2 to 3 hours, especially if using the standard charger that comes with the device.
