But aftermarket battery manufacturer Mugen Power thinks it has the answer -- user-serviceable battery replacement kits, which include instructions and tools for HTC One series owners to crack open their phones and perform a battery transplant.
A poll posting on the company's official Facebook page states --
We are looking into making extended batteries for HTC One Series phones that come with internal batteries. An intrusion manual will be provided to the user on how to open the phone and replace the internal battery with our battery with extended capacity.
As you may have seen, taking apart the One X in isn't for the faint of heart -- you'll need a generous supply of spudgers, some elbow grease and plenty of care if you want to take apart the phone and put it back together in working order. And of course doing so, even successfully, will void your warranty with HTC.
To us, this particular avenue sounds like a really bad idea, but all credit to Mugen for thinking outside the box here. Currently the self-service option leads in the company's Facebook poll, with the option to take the phone to a service center proving to be less popular.
HTC One owners, would you take your phone's life into your own hands and risk installing an aftermarket battery yourself? Let us know in the comments.
