Would a battery pack phone charger case discharge your phone faster?

So supposedly if you leave your phone plugged into a charger but the charger is not pluged into anything then it will discharge your phone faster, so if the charger cases have a charger connector constantly in your phone will it actually discharge it?

It depends on the topology of the switching power supply in the charger, but in general there is a diode in the output circuit that should limit the discharge current to the leakage current of the output electrolytic capacitor, which is small.

I'm not really reading anything specific, the question just sort of piped into my head haha. I had heard before that the battery would discharge faster than it normally would (not that they discharge much on their own anyways) and thought that maybe the cases do that too

That's one of the important differences between the PF and other forums. We do not allow "I heard" sources. If you have a link to a reputable source, please PM me, and I will re-open this thread.

I can say that the answer to this question depends on several factors. Firstly, the type and quality of the battery pack phone charger case will play a significant role in determining whether it will discharge your phone faster or not. If the case is of good quality and has a high-capacity battery, it is less likely to discharge your phone faster.

Secondly, the charging habits of the user also play a crucial role. If the user frequently charges their phone throughout the day, the battery pack case may not be able to keep up with the constant charging and may result in faster discharge of the phone's battery. On the other hand, if the user charges their phone only when needed, the battery pack case can provide a longer battery life.

Additionally, the amount of power being drawn from the battery pack case also affects the discharge rate of the phone's battery. If the phone is being used for power-intensive tasks such as gaming or video streaming while being charged, it may result in a faster discharge of the phone's battery.

In conclusion, it is not accurate to say that a battery pack phone charger case will always discharge your phone faster. The discharge rate depends on various factors, and it is essential to consider them before making a conclusion.
