The Xiaomi Redmi Note 10 Pro has three of those four at under £250.
Charge up is the efficiency of a full charge how much energy is drained from the wall outlet vs the energy capacity of the battery, as well as the efficiency of the charger and its residual consumption.
A mid-range Snapdragon 732G runs the show and is kept juiced up by a 5,020mAh battery that supports 33W fast charging, and thankfully, the charger is present inside the box.
You just have to remember to switch to it.
