Smartphones use lithium batteries. Lithium batteries do not have a memory effect, so when a new cell phone is used for the first time, there is no need to activate it several times by charging and discharging it, just load it as you go.
1. Please pay attention to the following precautions during daily use:
1. Please use the official standard charger to charge the battery to ensure that the charging voltage is stable and meets the requirements. Standards to avoid affecting battery usage.
2. In theory, keeping battery power in an average range (e.g. 30% to 80%) is more conducive to extending battery life. Therefore:
(1) After. the mobile phone is fully charged. It is recommended to unplug the charger to avoid charging for a long time or being in ahigh power state for a long time in order to accelerate battery aging and prolong battery life.
(2) If the mobile phone is idle for a long time, it is recommended to turn it off and recharge it regularly to maintain about 50% power. If the mobile phone is not used or charged for a long time, the battery may trigger over-discharge protection, resulting in abnormal charging or charging failure.
3. If the temperature is too high or too low, it will affect the battery life of the mobile phone. Therefore:
(1) It is recommended to try. Avoid charging and using it for a long time, especially at high power. In operating scenarios (such as watching videos, playing large games, etc.), long-term charging and discharging at high temperatures will acceleratehave battery aging. .
(2) Try to avoid using your mobile phone in environments with low or high temperatures or large temperature differences.
2. Extend battery life
1. Click Settings > Battery > Power saving mode to enable power saving mode.
2. Optimize power saving settings:
EMUI 11.0 and Harmony OS: Go to Phone Manager app, click One-Click Optimize and optimize power saving settings based on results.
EMUI 10.
First of all, let me explain the function of the charging board:
The charging method of rechargeable batteries is generally 4 state charging method, trickle charge -> cross flow charge -> constant voltage charge -> float charge
This better protects the lithium battery and can be fully chargede. This is the purpose of your charge card. At the same time, the power generation device of your bicycle is electromagnetic. induction. The power output voltage and power will be as the driving speed changes (the rated voltage and power represent the maximum output voltage and power), as far as I know, it is better that the voltage input of the load card is constant. , so that the output voltage for charging the lithium battery is relatively stable.
It is best not to charge the lithium battery with variable voltage. This will only damage the lithium battery. My suggestion is to buy a DC battery. -DC module. There is a 2-32V input constant adjustable output voltage conversion module on the market, the proportion reaches 80%, and can be used as a voltage protection and voltage stabilization version to convert thepower generation in.Connect the power generated by the machine to the output standard regulated voltage 5V by the voltage conversion module and connect it to a mobile phone or lithium battery charging board to achieve your goal. But you have to remember the protective link in the middle. be purchased from large capacity polymer batteries on the market. Lithium-ion batteries are safe and will not explode.
Everything is handmade, I hope you can adopt it~
