For the mobile phone with EMUI 3.0, enter the "Settings" interface, click "Power Saving Management" and switch to "Power Saving Management" to check the remaining power and remaining usage time.
Look at the battery contact point, the concave is real and the flat is fake. If there is a small hole next to the contact point, it is also fake, but it is not original! I have personally experienced that the logo of Huawei's red petals is true, and the largest petal has a white gradient. If the petals are all red, they are fake. If the printed font is pure white, it is true, and a little dark yellow is false.
The batteries used in Huawei mobile phones have undergone strict quality inspection before leaving the factory, so you can use them with confidence.
Take good care of the battery to make it last longer. These methods are as follows:
Please use the original charger to charge the battery.
Please try to avoid using your mobile phone while charging.
Please try to avoid waiting until the battery charge is lower than 20% before charging the battery. You can charge the battery when you use it to prolong its service life.
Please don't idle for a long time, and charge the battery regularly. When the mobile phone is not used/charged for a long time, the battery will be completely exhausted, resulting in abnormal charging or inability to charge.
Please avoid placing the mobile phone in an environment with low temperature, high temperature or large temperature difference, otherwise it will easily affect the service life of the mobile phone battery.
