I think there's a reasonable probability that your battery has failed. When mine failed, the big challenge was that no replacements were available that included the attached tiny circuit board. You may have more luck now finding one. As per some of my previous posts, I was ultimately...

Queue "Epic Trailer Theme"... It Lives!!! At least so far :-) Not sure whether the first repair attempt failed due to the bad joint, or I just didn't try the right boot-up sequence. The cell measured > 3.7V so I didn't think it would need a charge. When I resoldered it, I still wasn't...

I had to pull out my multimeter to test something else, so decided to recheck my battery connections. Turns out I do indeed have a faulty connection between the Li cell and the attached board (not with my solder joint but the cell itself has a stiff metal tab attached to the much more fragile...

You may have luck with support - if they give you a way to purchase a new battery and that solves your problem, please let us know. I didn't argue with them, but the only option they were offering me was to ship the unit overseas for possible repair. I'm in Canada with a unit no longer under...

mamema, please post the link to the battery you found on aliexpress. I did a search just now, and only found one product claiming to be for the x7ii - if its photos are accurate, it will not work (at least not without the board-swap surgery I alluded to with my last post) as its connectors are...

To remove the battery, you will need something to warm up the back of the X7ii. Also ideally a long, very slim and strong plastic putty knife or spatula. There is an adhesive pad keeping it stuck to the back of the case. If memory serves me (it was a long time ago now, check my past posts in...

I took the suggestion of corresponding with support - not surprising, "it seems to be a hardware issue". Meanwhile, after seeing photos on the internet of another X7ii powered up without the amp module attached, I decided to try that, connecting the jack up top to my amplifier. This time I was...

My X7ii has developed audio problems. I regularly use it as a DAC, but on Monday/Tuesday this week I used it for several hours on battery power, feeding audio via bluetooth to my truck audio system. The battery was down to about 25% when I put it back in the dock to charge. Several hours...
