So i have an old android phone OPPO R7f with a dead battery. I want to hook it up to my 3D printer and use it as a octoprint server using octo4a. I was planning to power up the phone via the printer''s power supply with a step down converter. And a maybe a resistor/capacitor(?) to trick the phone thinking that there is a battery connected to it.
The power at the input and output can be either alternating current (AC) or direct current (DC): power supply in order to convert the AC voltage coming in from the power grid to the DC voltage needed to charge your mobile phone''s battery. An AC/DC power supply transforms AC into a stable DC voltage. Single-phase AC/DC systems are
Electronic Circuits: Linear/Analog. Louis E. Frenzel Jr., in Electronics Explained, 2010 Power Supplies. A power supply is, as its name implies, a source of power to an electronic circuit.

The Starlink mobile power supply source, like the Jackery Solar Generator, Elon Musk tweeted on X that the basic camping solar panels and a little battery will power Starlink all day. The solar panels can be unfolded and placed under direct sunlight to absorb the sun''s energy and generate DC electricity.
Most of them will not accept it. There might be exceptions. If you want to power a cellphone from a power supply you will likely need the value of the thermistor that is used in battery pack for this phone. You probably see 3 or 4 connection points where the battery goes. One of those is for monitoring the battery temperature.
As for powering the phone direct from a low voltage supply you may be able to as long as its a regulated/switching power supply, which most are nowdays. Any voltage between 3.0 and 4.2 should work. Typically you want to aim for 3.6/3.7 though to give you a bit of wiggle room. However that's a bit of a wierd voltage for power adapters.
The battery monitoring system (BMS) will very likely be on the phone's motherboard, so a power supply would have to emulate a battery very convincingly for such a setup to work. In what scenario would you get hold of a phone with no battery significantly more cheaply than a phone with a battery?
The cell phone battery can be charged with a universal charger (pic) and will always be available when we go out. At least there is no damage to the battery that constant charging in the phone can cause, like swelling an overheating, and, also, constant use of the micro USB port is minimized.
External battery power. Tools needed, Multi-meter, soldering iron, small flat file, Stanley knife, hand tools. Q'bond. Parts needed, single or four row 18650 battery holder, twin-flex, plastic plate and contact strips for dummy battery plate. My first idea was to use a 18650 battery wired up to the + and - terminals in the battery compartment.
