I have several android devices, with problems that have been developing overtime. I am unsure what, exactly, the problems are, and am hesitant to declare it a hardware issue unless i can prove it. Some examples in particular are:
Phone 1: Charges slowly. Potential sources are: Battery is old and dying (default assumption) Wall outlet has electrical issues Charger has electrical issues Charging port has electrical issues Micro-USB charging cable has electrical issues Phone manufacturer is intentionally throttling performance to convince me to buy a new phone
Phone 2: Wi-Fi signal weak or barely functioning, youtube videos buffer and load for much too long on 720p when they shouldn’t need to. potential causes: wireless receiver aging router hardware issues digital connection issues intentional throttling of device functionality by manufacturer to convince me to purchase a new phone.
As you can see, there are many potential causes of these issues, some much easier to investigate than others. Is there any software that could help me in identifying the cause, especially the phone hardware and software related ones? I wouldn’t even really know where to start when it comes to this, it would take easily days for me to track this all down on google for both devices and frankly I’d really rather avoid that if at all possible.

No you dont need root to flash, but if you install magisk you need to flash the patched boot image therefore have bootloader unblocked which is needed. What I meant is that if OP decides to root with Magisk it’ll just be easier to install Lineages OS(if his phones are supported) than to search for the firmware file to extract boot image since Lineage offers it already extracted
