Xiaomi Mi 11 Lite Battery Replacement

Risk of overheating: exercise caution with heat sources.

• Apply an iOpener to the rear glass for at least two minutes, loosening adhesive underneath.
• Alternative methods include a hair dryer, heat gun, or hot plate.

Do not overheat the phone; display and internal battery are susceptible to damage.

Secure a suction handle along the right edge of the rear glass, as close to the edge as possible.

• If the rear glass is cracked, use strong tape or superglue to secure the suction handle in place and allow it to cure before proceeding.
• Lift the rear glass with the suction handle to create a small gap between the rear glass and the frame.

If you experience difficulty creating a gap, apply more heat while following the iOpener instructions to avoid overheating.

• Insert an opening pick into the created gap.
• Slide the opening pick to the top right corner to slice the adhesive.
• Leave the opening pick in place to prevent resealing of the adhesive.

Insert a second opening pick at the top right corner.

• Slide it down along the right edge to cut the adhesive.
• Leave it in place, keeping the bottom right corner open.

Reheat the adhesive with an iOpener for 1-2 minutes if it becomes hard to cut.

• Insert a third opening pick at the bottom right corner of your phone.
• Slide the opening pick along the bottom edge to slice the adhesive.
• Leave one opening pick in the bottom left corner to prevent resealing.

Insert a fourth opening pick under the phone's bottom left corner.

• Slide the pick along the left edge to cut the adhesive.
• Leave the pick in the top left corner to prevent resealing.

Position an additional opening pick under the top left corner.

• Slide the pick along the top edge of the rear glass to separate the remaining adhesive.

Remove the rear glass.

• Secure with pre-cut adhesive or double-sided tape.
• Apply pressure to the phone for several minutes to form a strong bond. A stack of heavy books can be used for this purpose.

Remove the motherboard cover using a Phillips screwdriver.

• There are eleven screws in total.
• The screws have a length of 3.4 mm.
• The screws secure the motherboard cover in place.

Insert the opening pick under the left edge of the motherboard cover.

• Pry up the motherboard cover using the opening pick.
• Remove the motherboard cover.

Disconnect the battery cable by prying the connector straight up with a spudger.

Disconnect the SIM card tray cable from the motherboard using the flat end of a spudger.

Use an opening pick to pry the graphite film away from the battery and loudspeaker assembly, starting from the bottom end of your phone.

• Work your way around the edges, carefully separating it from the surrounding components.
• Once separated, lift the graphite film away from the device.

Do not bend cables sharply, as this may cause damage.

• Fold the SIM card tray flex cable towards the charging port for better access.
• Use a small piece of tape to secure the cable if needed.

Never touch the capacitor terminals — risk of electric shock.

• Remove the orange adhesive strip labeled with an "A" using blunt nose tweezers or a clean fingernail to prevent damage to the battery.

Remove the orange adhesive strip labeled with a "B" from the battery using either a pair of blunt nose tweezers or a clean fingernail.

Lift the battery out of its recess by pulling on the orange adhesive strip.

• If required, apply a heated iOpener to the center of the display.
• Pull the battery off any remaining adhesive.

Remove the battery.

• During reassembly, temporarily reconnect the battery to the motherboard.
• Align and seat the motherboard correctly before disconnecting the battery.

Always clean and dry surfaces with isopropyl alcohol (>90%) when replacing adhesive stickers.

• If using new adhesive, apply it to the device's pre-cut locations, not directly onto the battery.
• Press the new battery firmly into place.
