Uber is reportedly increasing prices for customers with low battery levels, according to a report in Belgian newspaper Derniere Heure.
The investigation found that some users in Brussels claimed to have seen varied prices for the same trips depending on their phone battery percentage.
Derniere Heure conducted an experiment using two iPhones with different battery percentages, revealing a significant price difference for the same trip.
Uber denied the claims, stating that the app does not measure a user's battery level to calculate the price of a trip, and that dynamic pricing is based on demand and supply factors.
Uber drivers reveal reasons for giving passengers low ratings - Loud friends, leaving crumbs, and loading the car with bags might be why.
Loading luggage and taking time to load and unload it can cause drivers to lose money and lead to lower ratings, says an anonymous driver.
Bad manners in the car, such as slamming doors and banging suitcases, could bring down a passenger's rating, says a driver who has driven for the company for 15 months.
Tipping more can improve rider ratings, according to some Uber drivers - "even just a few dollars every ride".
