1. Most of the new mobile phones you just bought have around 30-40% of the electricity inside. Firstly, they are used for field testing and secondly, they are convenient for customers to use during testing. the machine in the future.
2. There is a lithium battery inside the mobile phone. It doesn't need to be charged for more than ten hours for the first time. It only needs to be charged for the normal duration, generally 8 hours. hours.
The first three charging times of lithium battery mobile phones
When calculating the formula, the charging voltage is not taken into account and the charging time is only linked to the charging current:
Charging time t=battery capacity c/charging current i
So,
The theoretical charging time with a charger is 1320/350 = 3.8 hours, or almost 4 hours;
The tea valueOric USB charging time is 1320/800 = 1.65 hours, or approximately 1 hour and 40 minutes.
But in practice, the charging time is longer than the theoretical time because there is energy consumption during charging. Increasing the charging voltage can improve charging efficiency.
Hello:
Based on your description, charging suggestions for newly purchased mobile phones:
1 After the first three full charges, charge 2 charges additional. -3 hours. It can be used every time after being fully charged.
Note: Do not recharge after the battery is completely exhausted, as this will affect its lifespan.
2. Do not use the mobile phone for a long time during the charging process. Please wait until charging is completed before using the mobile phone.
Here are some tips for using phone batteriesmobile phones:
1. Don't overload. You have to wait until the device prompts you for “low battery” to charge; wait until the device turns off automatically before charging it, because the battery has been over-discharged. This affects battery life.
2. Don't overload. When the charger gives a full indication, the charger should be unplugged. Current chargers generally have an automatic shut-off system. It is acceptable not to remove the battery from the charger for a short time. However, if the battery remains on the charger for a long time, the network voltage will increase late. at night and the charger will stop charging, once the voltage increases it will continue to charge causing the battery to overcharge. This affects battery life.
3. If the battery is not used for a long time, it should be charged to 60%, stored separately in a cool place.is and dry and recharged every 4 or 5 months.
