How many full charges?
We take 75% of the power bank's stated Wh and divide by this phone's 14.68 Wh. This remains a planning estimate.
18.5 Wh rated → 13.9 Wh planned delivery
37 Wh rated → 27.8 Wh planned delivery
74 Wh rated → 55.5 Wh planned delivery
(Power-bank Wh × 0.75) ÷ 14.68 WhA cold or older battery can supply less energy.
Cold and battery ageing+
The estimate uses the battery data and calculation assumptions shown with this result. That is not a measurement of the battery’s current condition. Cold and battery ageing are not calculated separately.
Cold is not the same as wear. Cold can temporarily limit the available energy and the power that can be delivered. Ageing can permanently reduce the storage capacity, even when the screen shows ‘100% charged’.
Follow the temperature limits for charging and using from the manual of your model. Check important applications with your own setup.

How many Wh does the Galaxy S23 battery store?
The model-specific source gives 14.68 Wh and 3,785 mAh. Watt-hours are the useful basis for comparison with a power bank.
How often can a 10,000mAh power bank charge the Galaxy S23?
A power bank rated around 37 Wh provides about 1.9 full charges in this estimate. We assume 75% of its rated energy reaches the phone battery.
Does 14.68 Wh mean the phone charges at 14.68 W?
No. Wh is stored energy; W is charging power at a particular moment.
