I changed the battery of the Mi A1 cellphone last week. The battery was so bad. It needs a charge even if I just used it for one or two hours as a hot spot.
I bought the battery from Tmall.
I paid 25 Chinese Yuan, about $5. That’s a great deal. I need to learn how to install it myself.
I open the case with the Youtube video.
First, disconnect the battery. Then remove a small part with a special screwdriver.
Here is the full picture. Two batteries side by side.
The tapes are too old and can not be removed, so I have to remove the battery with force.
It ends up with a bent battery. I am so worried about it.
Installing the new battery is easy.
I used one tape on the new battery.
Then, I put the cover back and turned on it.
I tested the new battery. With a full charge, I can use it for two days.
