Nice post the thing is i think that the boost converter might be for the solar panel that's if the output of the panel is low like 5volts and may one of the two ics is a pmw and the other a , as u said , mosfet

It's very possible that the panel voltage is being boosted, however I definitely think there has to be a boost converter between the battery and the USB ports, since 3.7 volts won't power USB devices.
Am going to take that ur an electronic hobbyist and i wanted to ask this boost converter does it stress the battery for high voltage amplification like from 3.7v to 12v using a li-ion battery
I don't have a ton of experience with boost converters, but I don't believe that the boost converters of any voltage should place significant stress on the battery unless drawing lots of current. Of course to get to 12V you'd need a different circuit than the one presented here.
For example I have a bunch of devices that step up batteries less than 3 volts up to thousands of volts with little drain on the batteries.
Thanks but could u help me with the circuit diagrams of this kind of circuits
Unfortunately I don't really yet have the experience to design any non-crude way to make a boost converter. However, if you look online there are tons of 4 volts to 12 volts boost converters that can take a Lipo voltage up to 12 V (you'll still need the lipo protection circuitry). Here's one:
