The battery life of your Samsung Galaxy A3 A300 is too short and you are tired of always connect your device to the charger?
Don’t worry! Today we will explain how to replace the exhausted battery of your smartphone!
What you need:
- Samsung Galaxy A3 A300 battery
- Plastic opening tools
- Heat gun
- Phillips screwdriver
Turn off the device.
Heat the touch screen for 5-10 minutes with a hot air gun;
Apply a suction cup and raise the glass. As the glass is partially raised, insert a plastic opening tool;
Disconnect the touch screen connector from the logic board, as shown in the picture below;
Go on with the removal of the touch screen, taking care of the Menu and Back soft keys. Help with a tool to unstick them from the old touch screen without damaging them. Put aside the Home button that must be placed again before reassembling the device.
Remove the SIM card and the microSD slots, helping with the eject sim;
Use a Phillips screwdriver to remove all screws from the middle frame;
Make sure to disconnect the Menu and Back keys and, with a plastic tool, take out the middle frame and motherboard (together).
Disconnect the battery flex cable, heat the battery with a heat gun for a few seconds and extract the battery pack.
Connect the new battery and reassemble the phone.
Done! Now your Galaxy A3 will look like a brand new phone!!
