Use this guide to replace the battery in your Xiaomi Mi 3 smartphone.
A phone’s battery stores the electricity the phone needs to operate. Recharging and using the battery causes the lithium-ion battery to degrade, decreasing the amount of charge it can hold and shortening its lifespan. If you notice you must recharge your phone more frequently, it may be a sign your battery is dying. Faulty, damaged, or improperly installed batteries can swell, overheat, or leak electrolytes which will cause damage to the phone.
Before beginning, make sure to power off your phone completely and disconnect from any external power source.

-
Firmly press the SIM card removal tool into the hole located at the top of the phone to eject the SIM card tray from the slot.
-
-
-
Remove the two Phillips head screws located at the top of the phone on either side where the SIM card was ejected.
-
-
-
Insert a pry tool into the upper edge of the phone, where there is a small gap between screen and frame of the phone to begin separating the screen from the rest of the phone.
-
-
-
Once the pry tool has been inserted into the phone, slide it around the perimeter of the phone while gently lifting until the screen panel and back panel of the phone separate.
-
-
-
Place the front panel screen side down with the camera at the top.
-
Remove these six Phillips head screws located at the upper half of the phone.
-
This screw is located under an orange sticker at the top right corner of the panel. The sticker can be removed with a pair of tweezers, then remove that Phillips head screw.

-
-
Remove the plastic cover on the bottom of the back panel by inserting the pry tool at the edge and gently lifting.
-
-
-
Remove the upper plastic cover from the back panel by inserting the pry tool into the upper edge and gently lifting.
-
-
-
Remove the battery by gripping and pull up on the "Battery Removal" tab attached to the left side of the battery on the back panel.
-
To reassemble your device, follow these instructions in reverse order.
Prior to reassembly of the phone, inspect the battery for any leaking electrolyte. Leaking electrolytes is a sign of overheating, which can further damage the motherboard or cause the phone to catch fire. Clean any electrolyte from the phone using a cotton swab that is slightly damp with vinegar or lemon juice.

Fr where do I gotta find a new battery after the removal of the old one???
Easily available on Ebay. I am about to replace mine 2nd time, work's fine though the discharge seems to be higher after almost a year of replacement. Phone's still good to go for another year or so hopefully. No serious lags :)
