Hello! At present, most mobile phone batteries are lithium-ion batteries, which have little memory effect, and the mobile phone batteries have been activated before leaving the factory, so it is good to fully charge them!

Those so-called first three times need to be charged 12 hours, just the legacy of nickel-hydrogen batteries!

In addition: Try not to charge the battery directly with your mobile phone. Using the mobile phone for a long time to charge the battery may bring some problems to the mobile phone!

It is recommended to use a regular manufacturer's seat punch, which can effectively prevent overcharging. Do not use the so-called universal charger on the market at present!

Moreover, excessive discharge is harmful to lithium-ion batteries, so it is better to leave some electricity for recharging!
