Samsung’s Galaxy S5 smartphone features a battery saving feature called Ultra Power Saving Mode. When the user enables this function, the Galaxy S5’s 5-inch Full HD Super AMOLED display goes into black and white mode. Phone calls, messages and the internet remain active under the colorless user interface. Samsung promises an extra 24 hours of standby time on a 10 percent battery level.
Some older model phones featuring LCD monochrome displays used less juice than the color displays of today’s handsets. The Nokia 5160 for example offered 4 to 8 days of standby time. According to Engadget (March 10), Chinese e-Reader maker, Onyx uses E-ink’s Electronic Paper Display (EPD) technology to prolong battery life on its upcoming mobile phone. Arriving in Spring 2014 is the MIDIA InkPhone featuring an EPD display. Housing an 1,800 mAh battery, the phone can last up to two weeks on a charge.
Russian company, Yota Device introduced its next generation YotaPhone, dual display Android phone at Mobile World Congress last month. It features an EPD display on one side and an LCD display on the reverse. Yota Device claims that the YotaPhone’s 1,800 mAh battery can deliver over 50 hours of reading time on it’s “always on” EPD smartphone screen. Similarly, with the black and white look of Ultra Power Saving Mode, Samsung offers two different ways to view the Galaxy S5’s Full HD Super AMOLED display.
As technology moves forward, it’s not just phone displays that can take a toll on the battery life of smartphones. Mobile phone manufacturers are producing handsets with advanced hardware specs including CPUs with higher clock speeds. The good news is that multi-tasking and overall system improvements are the result of high speed processors, allowing for a better user experience. On the flip-side, higher clock speeds and multiple running tasks can drain the phone’s battery life.
Higher carrier network speeds along with high clock speeds can also drain a phone’s battery fast. Mobile carriers throughout the U.S. offer high-speed data for seamless on-the-go Web browsing. The nation's top five carriers, AT&T, Sprint, T-Mobile, U.S. Cellular and Verizon use 4G LTE technology. With an average network speed of 17.8 Megabits per second (Mbps) nationwide, T-Mobile ranks above all carriers. Depending on the region, peak download speeds can reach as high as 150 Mbps.
To save battery life, many Android phone users apply system tweaks, toggle 4G LTE or install a battery saver app on their device. Potential Galaxy S5 owners may no longer feel the need to use battery saver apps since Ultra Power Saving mode is an option. Depending on preference, some users may choose to toggle Ultra Power Saving Mode or combine it with existing juice saving practices.
