Except no voltage reduction at all, I just put the USB 5V directly on the battery terminal and let the on-board voltage stabilizer deal with it.

I connected a charger directly to battery terminals of a smartphone whose battery failed, over Schottky diodes to reduce the voltage properly.

Now I have a phone which always shows 90%-100% battery.

I ran Tesseract OCR on its 4x64-bit ARM CPU over Termux and ssh and it adds another 50% computational power to my PC when I needed to OCR many pages of documents.

The power Schottkies were upcycled from dead power supplies, the cable from a broken power cord, the USB-A connector from a failed charging cable, I don't remember what the resistor and PCB comes from.

Ha i looked at that one but didn't read the text, and he didn't use the right diode symbol in the schematic lol

Oh that's interesting. I looked at a few when you first mentioned pummer as I'd never heard of it before and none of them showed a zener.
Which circuit did you use?

injured in an accident? Call Pummer and Schottky, personal injury attorneys

1N5818 is common.
