We tested the Samsung Galaxy S23 Ultra charging speed at 45W power determine if the phone has improved over its controversial predecessor.
Samsung is no different. Despite advertising 45W wired charging power since 2022’s flagships, it turned out to be a brief peak rather than a sustainable power level last year. The result has been handsets that mostly have solid battery life but whose cells refill barely any faster than they did when charging at the older power levels. Previous models still took about an hour or longer to charge, hardly that fast.
For this charging test, we opted for Samsung’s official 45W SuperFast Charging 2.0 travel adapter (model: TA845) to achieve maximum power. That said, any compatible 45W USB Power Delivery PPS charger from our list of the best Samsung Galaxy S23 chargers will achieve the same results as below. For comparison, we also tested a selection of other models that support different power levels and protocols.
For clarity, we’re tracking the time from 1% until the phone claims to be at 100%, not the time until the phone completely stops charging (fast charging doesn’t play a part in the trickle charge period anyway).
