Suggestion: Low-power mode

[Twister-UK]

Remember though that a (properly designed and functioning) device will only pull as much current from the source as its power supply circuitry allows, so simply connecting it to a higher capacity charger isn't always a solution.

That point is irrelevant. Most if not al smart phones can an will take advantage of having a 1, 2, 3, or even 4 amp charger.

Oh, it's anything but irrelevant. Some, perhaps even many, recent phones can take advantage of higher current chargers, but to suggest that most/all do is incorrect.

The other thing to remember that household chargers (that plug into the wall) are typically higher capacity than those designed for use in the car (due to the 120VAC vs 12VDC and the fact that the charger doesn't want to drain your car battery). Getting a higher capacity car charger won't have any effect on your battery while the car is running (unless your alternator is messed up).
