Getting this phone to turn on with a faulty battery to erase it?

This is (unfortunately) my 2nd S6 Edge+ with this issue, and I never found a way to get past it last time :/. The issue is the batteries tend to go bad because of the age of the phones and they just refuse to charge. This isn't even the first phone of these I had issues with; the last one is long gone (granted, I did put an aftermarket relabel in it, but even that one died the same way). Simply put, NOBODY SELLS A GOOD BATTERY FOR THE S6 series, hence why I just want to wipe it and dispose of it. Given the lack of good batteries, these old Samsung devices are effectively disposable now.

The USB port is also broken (screen replacement is needed for these), so it is beyond repair. As such, I'd much rather not buy a battery, which I will only use briefly. I got the last one working well enough to sell to someone to use as a trade-in device with a bent battery someone improperly removed (read: NOT A HAZARD, but it was done poorly), but I'm not doing that again.

Short of buying a battery for one-time use, is there a way to get these phones to turn on for data erasure, or will I have to disassemble it and drill the flash out?
