I stopped reading when I saw very difficult, working time needed 2 hours. https://de.ifixit.com/Guide/HTC+One+Battery+Replacement/30984

Any suggestions where I could have done this reliably?

Not a local option but one to consider:

They changed a battery in my wife's iPhone successfully and still working fine 4 months later. Check out the website for more info. They can arrange pickup and return from anywhere in Thailand or you can go to their location in Bangkok. And they offer 90 day warranty.

You could try Zoom in Airport Plaza, but I vowed years ago never to buy HTC after experiencing their dire service standards.

Linsy the link is certainly helpful http://www.drsmartphone.net/en/

But to give the still functioning Android away it's like cutting out my brain.

Brommers when did you go there? Any chance of new staff?

Yes, that is the downside, 1 week turnaround for our iPhone with no complications. To cover the period without the phone we purchased a cheap android phone which we now keep as backup. (A whole week for the Mrs not to have Facebook or Line wasn't worth thinking about)

sounds good. Requires transferring all data and wiping clean. I´m scared stiff :-) Will try to find help.

No need to "clean" the phone, send as is and hopefully should come back the same. Might be prudent to back up data and important info. Contacts if not already can be stored on your Google account making them available on any android device. Granted It is nerve racking but they should be able to answer your concerns and advise on what to do in preparation. Arno was my contact and his English was excellent.

Feel free to PM me if you have any further questions and I will help if I can.

One last thing from my experience, if you get a cheap spare phone try to get one that accepts the same size sim card as this can be a pain and make sure the frequency is compatible ie: 850, 900 etc.

Linesy, you could not be more helpful ( good enough to be marriage counselor ) ​I will run down the battery a bit more and then follow your suggestion. Love my HTC ONE, 3 years old and still running strong, elegant design gives me daily joy

Ive been to more than a few shops in CM. No one has this battery.

I have an M7 what version is you One?

I stopped looking after a couple shops had me make a deposit and they said they could order it in, then a week later told me not even their suppliers can find the battery.

Im not saying its impossible, but it seems to be overly difficult.

HTC One M7 batteries available on Lazada for about 800 baht.

SM mine is the first HTC One. Really no reason to replace it with anything. Will try to economize power consumption without reducing the functionality of the phone. I found a lot of waste in my way of usage. At the end of the road I will follow the suggestion of MR.LINESY

Only now saw the post of Mr Linesy. That is really surprising that the battery so difficult to replace is available by mail order. ( the website quoted in my original post talks about 2 hours of work)

The difficulty comes from having to take out and disconnect numerous parts just to get to the battery. Some of the parts are glued and taped. I considered a DIY job but weighed up the possible damage I could cause and left it to those that do this all the time with the correct tools. The 90 day warranty was also a deciding factor.

If it was a phone I did not care about I would have given it a go.
