Proper use of replacement battery

1. Avoid using up to 0% remaining.

If the battery level runs out and you leave it as it is, the voltage drops suddenly and may not be used as it is.

In the case of a lithium battery, the ratio of the depth of discharge is large and the deterioration becomes faster are proportional, which is the primary cause of battery deterioration.

2. Do not use the charger while it is plugged into the smartphone.

The ideal numerical value of the battery remaining amount is desirably used between 30 and 80%, leaving for 6 hours or more with charging and charging before going to bed will cause degradation to be advanced, so as much as possible

It is better to avoid it.

80% charging is more effective than 100% charging, which can suppress battery deterioration.

3. Avoid leaving under high temperature conditions, since the battery is sensitive to heat.

Lithium batteries are very sensitive to heat, and it is desirable to avoid leaving mobile phones in vehicles that are particularly prone to high temperature conditions.

4. Avoid charging with excessive voltage.

Charging with a high voltage adapter accelerates deterioration.

Please charge with the attached adapter or equivalent.

By keeping in mind the above things, battery life will dramatically increase, so please challenge by all means.
