Samsung today released a new ad for its Galaxy S5 smartphone, which mocks the iPhone for having both an unchangeable battery and a short battery life. The ad depicts forlorn iPhone users sitting along walls in an airport as they charge their iOS devices, while Galaxy S5 users eschew battery charging with Samsung's power saving mode and the Galaxy S5's replaceable battery.

"There they are. Clustered around power outlets, near the recycling bins, stained carpeting, and bathrooms. Tethered to the wall. Denied the freedom to enjoy even the most basic things, like grabbing a drink, or sharing a laugh with your co-workers. Or sitting with someone you know. You're stuck here until your battery says so."

An iPhone user charging his battery looks up enviously at a Samsung user, asking "Are you changing your battery? Is that the new Samsung?" While another Samsung user turns on power saving mode to save battery. "Don't be a wall hugger," says the ad.

Unveiled in February, Samsung's 5.1-inch Galaxy S5 is its newest flagship device, with a fingerprint sensor, a water resistant casing, and a heart rate sensor. One of the device's most highly-touted features is an Ultra Power Saving Mode, which activates a black and white display with limited app access when the phone's battery is low.

In power saving mode, users only have access to basic phone functions, such as making and receiving calls, accessing email, and browsing the web. It limits cellular connectivity to 3G, turning off LTE, and it also disables WiFi and Bluetooth. According to Samsung, this provides an additional 24 hours of standby time with less than 10 percent of battery left.

Apple does not have a similar power saving feature on the iPhone, nor does it have a removable battery like the Galaxy S5, but users do have quick access to settings like WiFi and Bluetooth, along with options to disable battery draining features like background app usage and location services. iOS 8 also adds a function that lets users see which apps are draining the most battery.

Samsung often turns to iPhone bashing to promote its Galaxy line of smartphones, with its most well-known commercial series depicting iPhone owners waiting in long lines for new iPhones while enviously eyeing Samsung devices.
