새 휴대전화는 "배터리 활성화"가 필요한가요? Posted by batterymanufactory.com

3월 05, 2025

When buying a new mobile phone, many people will hear such advice: "The first charge should be fully charged for 12 hours" and "The first three times, the battery must be fully used and then fully charged to activate the battery." These sayings have been passed down from generation to generation by the elders, and are even regarded as "maintenance secrets" by some businesses. However, these suggestions actually come from battery technology that has long been obsolete. This article will trace the origin of the saying "activate the battery", analyze the characteristics of modern lithium batteries, and provide a scientific guide to charging new mobile phones.

새로운 휴대전화

I. The historical roots of the saying "activate the battery"

1. "Memory effect" in the era of nickel-metal hydride batteries

In the era of feature phones, mobile phones generally use nickel-metal hydride batteries (NiMH). This type of battery has an obvious "memory effect": if it is charged without being fully discharged, the battery will mistakenly think that the remaining capacity is a new "starting point", resulting in a gradual decrease in available capacity. Therefore, users need to fully charge and discharge regularly to "calibrate" the battery to maintain performance.

2. The disruptive innovation of lithium batteries

After 2000, "lithium-ion batteries (Li-ion)"completely replaced nickel-metal hydride batteries with advantages such as high energy density and no memory effect. However, the old concept of "activating the battery" lingers and is even mistakenly transplanted to lithium battery devices.

II. Lithium batteries do not need to be "activated" at all

1. Activated at the factory, no user intervention required

Modern lithium batteries have completed the formation process before leaving the factory:

First charge and discharge: The factory will charge and discharge the battery 0%-100% to activate the internal chemical materials.
Pre-charge protection: When a new mobile phone is turned on, it usually has 50%-70% power. This is the "safety power" deliberately retained by the manufacturer and has nothing to do with whether the battery is activated.

Conclusion: The new mobile phone can be used normally after it is received, without any "activation ceremony".

2. The three core characteristics of lithium batteries

No memory effect: No need to fully charge and discharge, charging as you use is healthier.
Fear of extreme power: Keeping 0% or 100% power for a long time will accelerate aging (laboratory data: full charge storage for 1 year capacity decays by about 20%, while 50% storage only decays by 4%).
Limited cycle life: The life of lithium batteries is calculated as "full cycle number" (for example: charging from 50% to 100% counts as 0.5 cycles), usually after 300-500 cycles, the capacity drops to 80%.

III. The correct way to charge a new phone

✅ It is recommended to do this:

1. Charge as you use it to avoid running out of power

You can charge when the power is less than 20%, without waiting until it is turned off.
Avoid keeping the power at 100% for a long time, charging to 80%-90% is more conducive to extending the life (can be achieved through the "Optimize Charging" function).

2. Enable smart charging management

iPhone: Settings → Battery → Battery Health → Optimize Battery Charging.
Android phone: Settings → Battery → Adaptive Charging/Smart Charging (different brands have slightly different names).

3. Pay attention to heat dissipation and avoid high temperatures

Remove the phone case when charging, and avoid placing the phone in a closed environment such as a quilt or pillow.
Avoid playing large games while fast charging (high temperature is the "number one killer" of lithium batteries).

❌ Don't do this:

Charge for 12 hours for the first time: Overcharge protection mechanism has long been popularized, and the power will be automatically cut off after full charge.
Deliberately charge and discharge completely: Deep discharge will damage the electrode material and shorten the life.
Superstitious third-party "battery calibration" software: The system's own power management is more reliable, and forced calibration may be counterproductive.

IV. Summary: Instead of "activating", it is better to maintain scientifically

The progress of lithium battery technology has long made "activating batteries" a thing of the past. Instead of getting entangled in unscientific charging rituals, it is better to develop the following habits:

Charge as you use, avoid extreme power
Make good use of smart charging functions
Stay away from high temperature environments

Remember: Batteries are consumables, and there is no need to worry about the capacity decay of 20% after 2-3 years of normal use. Mobile phones are tools to serve life, and there is no need to sacrifice convenience due to excessive maintenance. Scientific use and rational view of loss are the real secrets to extending battery life!
