Reply to comment by Wagamaga in Recyclable mobile phone batteries a step closer with rust-busting invention. Rather than disposing of batteries after two or three years, we could have recyclable batteries that last for up to nine years, by using high-frequency sound waves to remove rust that inhibits battery performance by Wagamaga

Gonna be honest here, I'm starting to wonder what cheap ass, peak capitalism, planned obsolescence kind of back end products most people buy for their batteries to last only 2-3 years.

I've had phones with li-ion batteries that still work for 8+ years. The motherboards and protective plates have started to corrode and the plastic has started to degrade and fall off in chunks, but the batteries don't shows any wear and tear. And that was a $350 low/mid tier phone at the time. I'm even thinking of rooting it to install a custom Rom and give it a few more years of life, if I can find a back plate replacement cause the buttons fell off.
