On most models, when the mobile device connects to AC power, the battery normally recharges. Laptop batteries are usually modules with one or two release latches that are used to remove the module. Smartphone batteries either have a release latch or you slide part of the phone away and reveal the battery.
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.
It would start up but then switch off. For the S4 I used a laptop power supply with a 19 volt DC output at 3.5 amps and figured that if it is able to power a laptop with the battery removed it should be able to handle the phone easily. It did.
Keep battery contacts clean with a dab of rubbing alcohol on a lint-free swab once a month. Use your mobile device until the battery is drained when possible and then recharge it. Constantly recharging the battery reduces the battery life. Most lithium batteries have a circuit that keeps the battery from being discharged completely.
The power management IC on a mobile phone PCB regulates the power supply to different components of the device. It receives power from the battery and converts it to the appropriate voltage levels required by different sections, such as the processor, memory, display, and camera.
For the S4 I used a laptop power supply with a 19 volt DC output at 3.5 amps and figured that if it is able to power a laptop with the battery removed it should be able to handle the phone easily. It did. My latest attempt to power the Fame was a 12 volt, 2.55 amp half wave rectified AC/DC supply which works perfectly.
power supply
Ckt depends on the battery, it already has some electronics inside, but this is different for every battery. The charger should communicate with the battery chip inside to determine how to charge (CC or CV stage). So you would need a bit of back-engineering to determine the circuit.

Mobile Device Power
Use your laptop with battery-provided power. Ensure that a laptop that has an Li-ion battery is not plugged into an AC outlet all the time. Calibrate a laptop battery according to manufacturer instructions so the battery meter displays correctly. Computers are designed to work within a range of temperatures, but sudden change is not good for them.

How do batteries work? A simple introduction
When you plug a cellphone or laptop into the power supply, the lithium-ion battery inside starts buzzing with chemical activity. The battery''s job is to store as much electricity as possible, as fast as possible. It does this through a chemical reaction that shunts lithium ions (lithium atoms that have lost an electron to become positively charged) from one part of the …
