How to Properly Charge Phones for Long Battery Life

The battery is a critical part of any mobile device. Numerous incidents of cell phones exploding have been reported, often due to battery issues.

Furthermore, the battery serves as the lifeblood of the smartphone, keeping it operational. As a result, many people take battery capacity into account when deciding to purchase a cell phone.

Thus, it is not surprising that many people prefer to choose cell phones with large battery capacities. In fact, some people look for smartphones that support fast charging technology to get a phone with a reliable battery.

In reality, the battery on a mobile phone has nothing to do with capacity or fast charging technology. The fundamental aspect of battery durability is how the battery is charged.

No matter how large a battery capacity is, if you use and charge it improperly, the battery's capacity will decrease and it will be wasteful.

Therefore, it is very important that you understand the proper method to charge your cellphone to ensure a long-lasting battery and consistent performance. So, how to charge a cell phone properly? Let's check out the details.

1. Use The Original Charger

The most efficient way to charge a cell phone is by using the original charger. It is specifically designed to safely and effectively charge the battery of your mobile device. However, this is often overlooked, particularly when individuals forget to carry their charger and end up borrowing one from someone else.

Actually, using other chargers is not bad. It's just that the effectiveness of the USB charger you use will be different, particularly in terms of amperage.

Chargers come in different amperages, typically 2A or 1A. This variation can influence the charging process, particularly if your phone is capable of supporting 2A amperage.

Nonetheless, the most reliable method to protect your phone is to consistently use the original charger. Some chargers of inferior quality can pose risks to the battery.

2. Charging in Less Than 100%

There are lots of misunderstandings regarding full charging on cell phones. Some argue that if a battery isn't charged to 100% before being unplugged, it could negatively impact performance. However, in reality, it's optimal to charge a cell phone up to about 80%.

Those of you who usually unplug the charger when your cellphone's battery is only 80% to 90% charged, please do not need to worry about damaging the battery quickly. In fact, overcharging has the potential for decreasing battery life.

3. Charge It Before It's Completely Drained

The next ideal method for charging a cellphone is not to wait until the battery is completely drained. Rather, begin charging when the battery level drops to around 30-40%.

Avoid letting the battery drain to 0% before recharging it. This practice, if repeated often, can shorten the battery's lifespan. Ideally, the battery should not drop below 20% charge. Habitual charging when the battery level is below 15% can negatively impact its longevity.

4. Turn off Your Phone while Charging


The best method to charge a cell phone is to turn it off while it is being charged. Actually, it is possible to charge the phone while it is on, but it is preferable to charge the phone while it is off. This could improve the cell phone's durability and safety.

5. Lowering the Display Contrast on the Phone

If you are charging your smartphone while it is on, you should first lower the screen's contrast. Why? Because the brightness level of the screen is a primary contributor to battery consumption. Therefore, for optimal charging efficiency, lowering your phone's screen brightness is recommended.

6. Avoid Using the Power Bank Frequently

A power bank is a common electronic travel companion for many people. This item is a lifesaver if you want to remain connected to your cellphone when the battery is nearly dead. Typically power bank is used when there are no available places to charge the phone, such as when traveling.

Using a power bank to charge your phone is completely normal. It's just that its use should be limited to emergency situations only.

Constantly charging your phone with a power bank can potentially harm your device. Therefore, it is very important to avoid over-reliance on power banks for charging.

7. Avoid Charging via the USB Port on a Computer or Laptop


A cellphone needs to be directly plugged into a power plug terminal when being charged. Do not charge your phone using the USB port on your computer.

Actually, it is okay as long as it is an emergency situation. However, charging via a USB port on a laptop is slow as the input amperage is normally just 0.5 A, meanwhile your phone has 1.0 A or 2.0 A.

Therefore, if you prefer faster charging, plugging your phone directly into an electrical outlet is the most effective method.

8. Removing Off the Phone Case

If your cell phone is protected by a case, it's advisable to remove it before charging. Some cell phone models typically tend to heat up when being charged with the case still attached. Usually, this heat is caused by the obstruction of heat dissipation during charging.

In regards to modern mobile phones, this is no longer particularly relevant. Nevertheless, you should still remove the case. We can say that the casing is clothing attached to the phone; when the phone is overheated, removing the clothing is the proper action, especially when the phone is plugged into electricity.

9. Charge Your Phone in the Morning


Many individuals have a habit of charging their mobile phones overnight, often with the expectation that they will wake up to a fully charged battery.

If it happens on old-fashioned cellphones, overnight charging can indeed damage the battery. Some phones even require you to disconnect the charger as soon as the battery is fully charged.

However, modern phones are equipped with automatic circuit breakers, eliminating the need for immediate unplugging. As such, many individuals aren't concerned about leaving their phones charging overnight.

Nevertheless, while it's generally safe to charge a phone overnight with modern models, it's worth noting that the optimal time for charging is in the morning before embarking on your daily work or activities.

10. Use The Original Battery

This tip applies to old phones with removable batteries. If the battery life of your device has decreased, you should replace the original or built-in battery.

The use of fake batteries has the potential to harm mobile devices. Your phone will take a long time to charge. In the worst-case scenario, it can damage your phone.
