Is it harmful to charge electronics too long? I often leave my devices charging all day long after I go to work.

it depends on technology of battery. most of devices have a electronics for regulating charging,so it isn't problem if this electronics work properly

hi @linburger The mordern days batteries are safe , the have overcharge protection circuits to ensure safty. Lithium-ion operates safely within the designated operating voltages; however, the battery becomes unstable if inadvertently charged to a higher than specified voltage. Prolonged charging above 4.30V on a Li-ion designed for 4.20V/cell will plate metallic lithium on the anode. The cathode material becomes an oxidizing agent, loses stability and produces carbon dioxide (CO2). The cell pressure rises and if the charge is allowed to continue, the current interrupt device (CID) responsible for cell safety disconnects at 1000–1,380kPa (145–200psi). Should the pressure rise further, a safety membrane on some Li-ion bursts open at about 3,450kPa (500psi) and the cell might eventually vent with flame. be careful

If you are using the correct charger for the battery, there's no problem. If you are using, say, a variable power supply, you need to monitor the voltage & current, otherwise you might overcharge the battery and cause possible damage.

Battery life principle,pick up the voltage to give tension. if the principle is violated, leading to a reduction in service life.

No, it's OK with factory charger. It's harmful to charge frequently, because all batteries have limited recharging cycle.
