Customer ServiceThe internal resistance is the main cause of "wasted" power (converts it to heat) and loss of effective capacity, so as it increases, more power is wasted and capacity reduced. With respect to a power pack or power bank, think of them as just a "charger" for the battery in question.
If the power pack is charging the battery then current is going the battery, not out of it. The power pack must also supply whatever excess current the phone needs to operate. Once the battery is fully charged it will accept no more, so the current from the powerpack goes towards running the phone.
Since voltage also drops as the battery discharges, the increased resistance causes it to reach cutoff voltage earlier and so reduces its effective capacity. An old lithium-ion battery which is not powerful enough to run the device it was designed for may still be useful in a lower current application.
If the phone is being operated from the power pack (which is what I assume you meant by 'carrying a powerpack') then the internal battery doesn't waste any power because it isn't being used. Thanks, maybe it's worth editing that into the answer.
Another study from ‘Fraunhofer’ predicts that the installed battery capacity has to be increased up to 400 GWh in a worst-case scenario . Here, the storage capacity has to be eight times higher, since the consumers are not willing to change their behaviour. Therefore, more energy has to be time-shifted.
The capacity is very important in EVs as it limits the cruising range. Accordingly, the battery in EVs has to be replaced if the capacity is below a defined threshold value. For stationary BESS, the energy density is less relevant than for EV as size and weight of the battery system is not limited by design as in EVs.
