New Power Amp Tech May Double Cell Phone Battery Life
Two MIT electrical engineering professors claim to have made a breakthrough in power amplifier design that could lead to major gains in the power efficiency of cell phones. Joel Dawson and David Perreault, working for an MIT spinout company called Eta Devices, have figured out how to manipulate the power needed by cell phones when in standby mode to improve battery life. Power amplifiers operate in low-power standby modes (receiving) and high-power output modes (transmitting). In modern devices, however, the standby mode is kept at an elevated state in order to prevent signal distortions that occur when the devices jump from low-power to high-power. Keeping the standby mode at an elevated state wastes power. Eta Designs has created a way to rev the standby mode up and down at a rate of 20 million times per second without signal distortion in order to keep the power amp in the lower-power standby mode as much as possible. Eta Designs said it is tackling this same issue at cellular base stations first, where it hopes to halve the $36 billion annual expense of powering base stations. It will then follow up with cell phones and smartphones.
Hands On with the LG X power
LG announced the X series devices earlier this year, but IFA afforded us the first opportunity to take a look at LG's mid-range devices. The X power packs a huge 4,100mAh battery for extended use.
Cricket Launches Two Galaxy Amp Handsets from Samsung
Cricket Wireless today announced the Galaxy Amp Prime and Galaxy Amp 2 (pictured), two low-cost Android smartphones from Samsung. Both devices ship with Android 6.0 Marshmallow and Samsung's software customizations, such as Quick Launch for the camera.
Cricket Wireless to Sell LG X Power
Cricket Wireless today revealed plans to sell the LG X power smartphone beginning August 26 for $160. The X power, announced by LG earlier this year, features a 4,100mAh battery with Qualcomm Quick Charge 2.0 that delivers up to two days of battery life.
Huawei Touts the Dual-Camera Honor 6X
Huawei today announced the Honor 6X, a follow up to the 5X that improves upon specs and design. The 6X boasts a 2.5D curved glass front and aluminum rear panel to give it a metal-and-glass chassis.
