    As of Jan 2018, the battery adhesive strips are not in the parts list above. (Maybe they were at one time, but are no longer available?) I used some very small 3M Command hook adhesive strips instead.

Will the device boot up with no error message after replacing it with new battery? Or do you need some programming before or after replacing it?

Christian Duane Co - Réponse

There is no error when battery is changed.

Just successfully changed my battery without any issue. Booted up normally and able to do everything I was able to do before.

Thank you for the awesome guide :)

The Sony Experia Z5 Compact is water and dust proof. Will heating the back after putting it back on reseal the phone - or is there another step that needs to be added?

Steven Cox - Réponse

You can watch the repair video on youtube: https://www.youtube.com/user/lagaiPhoneS..., but I fixed it here https://lagaiphone.se/shop/sony-z5-compa... they used the adhesive but no water resistant warranty after repair. so far so good!

Pretty annoying, this mentions NOTHING about the battery adhesive strips to order separately, and neither of the “things to buy” come with them. I just replaced my battery, but it’s just flopping around inside at the moment. Where do I order the battery adhesive strips to adhere the battery to the motherboard? Note for others doing this too, you NEED the adhesive strips separately beside the battery and the back adhesive!

Yeah I ran into the same issue, I found them at https://www.teknikdelar.se/mobilreservde... but that's a Swedish company I think. I made a suggested edit to this post, suggesting the need for strips to be at least mentioned but I got a reply of “just use some tape".

It doesn't work for me. Connected the battery as it was and can't get it started and now I'm screwed. Such a waste.. What could possibly be wrong?

Thanks so much for this guide… and people who have commented for extra tips like the battery strips!

Phone booted up perfectly and everything seems to be working. Thrilled that I should have some extra time with my phone before having to get a new one.

All in spent around £10 - Took me about 2 hours to do but I’ve never done anything like this before and some things took me a bit longer to figure out. (I only got one adhesive strip though there are two in there, one seems to be holding okay though.)

I wrote some additional comments for the steps here to help anyone who like me is new to this. (Wasn’t enough characters to do it here.)

Oh I should have read your comments about the flex cable connectors. :+1:

per.tautorat -

Thank you for this guide, everything worked good for me. I replaced the Camera module and USB connector too,

But I am missing one thing in this manual. How to reconnect the flexcables for lcd and mainboard properly? Is there any special trick, i am really thankful that I somehow not destroyed the cable, nor the connector. But I think I was kind of lucky…

per.tautorat - Réponse

Very nice guide!!!

Two things that weren’t immediately clear to me, so maybe useful for others as well:

- Step 2: the back cover is only glued at the edges

- Step 9: the white part of the main and LCD flex connectors turns upwards to unlock it

I followed everything, and the battery seems to work. A few tips on step 9 would be great, though. But now the display is not showing anything. But it seems the touchscreen still works, I get sounds and vibrations when I press on the parts where the numpad use to be for the decryption of the hard drive. Any Idea on how I could bring this to a full success?

I undertook the battery replacement and put a new charge port in while I was at it.

After putting the phone all back together and powered it up everything appears to work on the screen functions but the phone no longer reads the SIM card or recognises my WIFI. This has rendered the phone unusable. I have tested the SIM in another phone and it is OK. The phone recognises the SIM and does a restart but then does not read the SIM card once it has restarted and displays the message “No SIM card - Emergency calls only”. It is as if the SIM card reader is not working.

I spoke to a technician and he said he wears a wrist band with a wire connected a metal earth to eliminate static electricity in his body going through the phone and short circuiting it causing damage. Could this possibly what has happened to my phone as there was no mention about having the earth yourself while undertaking the battery replacement.

Does anyone have an explanation or solution to my SIM card not reading?

An update on my last post. I managed to get my phone to connect to WiFi but I had to be right next to my modem to get a strong enough signal. Could this mean an aerial problem?
