8 steps

Switch off device
Switch off the device.
Press and hold the Power button, until you see a menu.
Choose the Power Off option and tap again to confirm.
Remove the back cover
Be extra careful with this step, as splintered glass could injure you.
The back cover is glued to the display chassis. So you need to heat the back cover and pull it off using a suction cup.
Place the suction cup as low as possible on the back cover, over the text.
Pull on the suction cup while pressing the frame against the table using a pick. As soon as a gap between the frame and the cover opens, you can carefully stick in your pick.
Move the pick along the device edges to unglue the cover all around.
The fingerprint sensor is attached to the back cover. It's connected to the mainboard with a flex cable. Be careful when liting off the cover, so you don't damage the cable and the PCB.
Carefully lift up the back cover. Fold it up along the short edge of the device. You should be able to see the flex cable now.
There's a small tape strip over the flex cable connector on the back cover. Pull it off and then use tweezers to pull the cable out of its socket. Keep the tape strip to attach the flex cable later.
Once the back cover is disconnected, you can put it aside.
Disconnec the battery
1 × 2.7 mm Phillips

Remove the screw on the battery connector's bracket. The bracket is latched in on the other side, so remove it carefully.
Now you can unplug the battery.
Remove the battery
You can remove the mainboard to get to the battery more easily. You can see the steps in the display replacement guide.
Careful: The battery bends very easily. Heat the display several times until the glue is very soft and the battery comes out easily. You can also try pulling off the battery with a suction cup, if the glue isn't too strong. Or you can order a new battery with your display and discard the old one.
The battery glue is very strong. To get it off, you need to heat the device from the display side using a heat gun. Don't heat the battery directly.
Then slide the broad end of the battery spudger under the battery on the long, upper edge. Here the glue strip is a little thinner than on the other sides.
When the battery comes off on one side, you can pry all around with the spudger and unglue the other spots.

Insert battery
If you're replacing the battery, you can cut out double-sided tape or pull off and reuse the tape strips from the old display.
If you're using a new display, it will come with stickers for the battery. If necessary, pull off the protective films now.
Put the battery in the device. Make sure it's facing the right way and then press it on all around.
Make sure the connector is over its socket, so you can plug it on easily.
Connect battery
Connector

1 × 2.7 mm Phillips

Put the battery connector on its socket and carefully plug it to the mainboard.
Latch in the bracket's lower end and fasten the other end with the Phillips screw.
Attach back cover
Slide the fingerprint cable's plug into it's slot on the back cover. There are two small tabs on the left and right of the plug; slide in the plug until it stops.
Attach the plug using the old tape patch or cut out a 2x2 mm square of tape.
Attach the back cover the right way around. Heat it again to make the glue softer and then press it on for a longer while so the glue can cool and bond.
The flex cable is very sensitive. Make sure you don't twist it. The best way to attach it is as you see in the images.
Test device
Now switch on your device and test all important functions:
Touch/brightness: test the highest and lowest brightness of your display. Drag any app across the screen in a zig-zag pattern. If the app follows your finger, the screen is ok.
Charging function (connect USB)
Front/back camera
Vibration motor
Volume/standby buttons
Earpiece / speaker / microphone
