Chosen Solution

Hi everybody, Due to the incredibly bad battery performance of my HTC One A9s, I decided not to buy a new phone but to replace the battery. However, I bought the battery and a little stick/tool to open the backside, but it does not open without any potential damage. Since it has a clear opening and something like a groove in its design, it shouldn’t be that difficult, right? There appears to be no information or youtube-vido whatsoever on this topic on the internet, so can anybody help me getting it done? Thank you a lot in advance, Kamil

You open the HTC One A9s from the front. The screen is glued down with adhesive. I recommend using an iOpener and a set of Opening Picks. Here is a YouTube video detailing the repair: https://www.youtube.com/watch?v=qSWMFBcW

Thank you so much! But that video is for the A9, is it the same procedure for the A9s? Thanks!

you go in through the front

Same problem for me the A9 seems totally different to A9s, A9s looks like rear panel to access for battery access
