    • The black screws are 2.8 mm in length.

  • The black screw next to the camera and the flash is covered by a sticker. This screw can be easily removed as if there were no sticker on top of it. The point of the screwdriver should be able to pierce through the sticker easily.

Use a plastic opening tool to remove the inner phone backing. The parts of the inner backing held down by two strips of double sided tape can be easily loosened by inserting the plastic opening tool underneath it and gently lifting it up.

Note the position of the speaker unit so you can replace it in the correct place during reassembly.

  • Take the speaker out of the back of the phone. It should come out easily as soon as the inner back is removed because nothing is holding it down in place anymore.

This antenna does not need to detach. I have broken the whole housing, the soldering part too.

This antenna not link to battery, not requires to detach.

You are removing the yellow tape to release the ribbon cable which slides out of the connector quite easily.

I had a strip of very hard/sticky glue on the left side of the phone/antenna side that made this part very difficult and made the metal housing bend. My phone is from Hong Kong so this could the reson.

You can remove the glue by pulling it from under one of the ribbon cables at the top of the battery. There is a youtube video showing it if you search zenfone 2 battery removal

Carefully insert the metal spudger between  the battery and its metal housing and then slowly pry the two apart. Be careful when prying the two apart as to not bend the outer edges of the metal housing because this will make it a lot more difficult to put it back into the phone.

Great job with excellent photographs and detailed explanations! Unfortunately this phone is a real goat rodeo when it comes to just replacing a battery. My phone froze and nothing seemed to help unlock it. Fortunately, I went back to an Android site and found the answer and was able to reboot it (holding the on/off button for 10-15 seconds) without trying to remove the battery. Thanks to you I've learned two valuable lessons.

@angus: I have exactly the same symptoms on my Asus zenfone 2, two years old piece. I have not yet replaced battery. It suddenly went dead, no charging,, only vibrates on its own.

I m in Abu Dhabi. What to do? Any experience you can share to help?

@angus I think its the two connectors located on top of the battery, one is for the screen and the other for battery + sim + speaker, check them to see if they are still well plugged.

Hi, I'm experiencing the same problem... Few weeks ago I replaced the screen, and the phone was perfect until two days ago when I didn't charge anymore and I decided to switch it off when the battery was 5%. It didn't turned on anymore... only the vibration works too much (each five minutes!). To be honest in the last period the charger didn't work well... I had to put it in a specific position to let the phone charge. Now I would like to change the battery but the original one that is on amazon is quite expensive and I'm not sure that in the end the phone will work. Did you solve the problem? How many are the possibilities that chancing the battery I will get my phone working again? Thanks a lot, Miriam

when assemblying back it would be easier to put the battery in as the first step, connect it to the mainboard, and then cover with the metal shield assembly. Thanks for the guide!

Which is exactly the parts that charge the battery? I have charging issues after a battery replacement and I've tried to replace the dock station with no results.

Why my phone do not support fast charging after changing battery?i replace with original battery..pls help me

Luqman - Reply

Very well explained; unfortunately is most cases, to reassemble is the most difficult part and the connectors are not mechanically fitting together, they are just applied by the machine-robot with a precision difficult to attain by hand; as a result, the phone is dead forever with your new battery; more and more phone makers use non-replaceable batteries so you have to buy a new phone instead of a new battery, which is much more lucrative. They business model is not your happiness but to make money, so phone are made to fail quickly by design.

Thank you very much for this excellent step by step explaining. The hardest part for me was putting back the antenna into its home, this is mostly because of that I was really anxious to ruin it.

My phone wasn't charging nor starting up. After I removed the battery using this instructions and put it back, the battery gets charged now.

I thank you again, you saved a lot my time and money.
