Einleitung

Battery no longer lasting a full day? Tried factory reset and still have the same battery life? If you answered yes to any of these then a battery replacement could very well do the trick. Requiring just a few minutes of time, you will be up and running with a recharged tablet ready for what ever is next.

Where can you get a new battery? Do you have a model number?

Additional information: I have Chuwi Hi9 Pro CWI 532 not 548 but according to the picture the the presented wiring and battery placement seems to be the same (buttons are not). Back to the post: the removed flex cable is not the battery cable it is the LCD cable (yellow rectangle). The battery is soldered with 3 cables, see the bottom right corner of the battery on the Step 2 picture. Be very careful when desolder these cables: do one at a time and immediately insulate the soldered out wire to make sure there will be no shortcut. Shorting the red and the black cables could cause even fire if not paid enough attention to this step. Battery glued by two strip to the metal backplate. The strips can not be accessed at the stips’s end because there are shorter than the battery. The strips are strong and can not be heated effectively: you will heat the battery or the screen, be careful doing that. What I recommend is use a thin plastic wire to cut the glue.

Thanks for the useful information. I updated the guide to reflect the part where it needs to be soldered. I did not notice those wires down there at first but that makes complete sense.
