Does OPPO charge 2 1 hour have any effect?

Don't worry, it's okay. It's a long time since the new mobile phone was activated after charging 12 hours. It's aimed at the previous Ni-MH battery and Ni-Cd battery, which is totally unsuitable for the current lithium battery! Fortunately, the current brand mobile phones have anti-overcharge protection, otherwise charging according to your method will harm people!
