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.
