Considering that our smartphones, unlike our feature phones from back in the day, do a lot more than just making phone calls and sending text messages. We can take amazing photos, high quality videos, surface the web, watch videos in QHD, play 3D games, and etc., which is why it is unsurprising that smartphone batteries last as long as they do.

However perhaps to boast and show off their technology, Qualcomm has recently released a video in which they show how their chipsets are good at conserving energy, so much so that they tested it out with a OnePlus One handset (which sports a Snapdragon 801 chipset and a 3,100mAh battery) and managed to squeeze a good 60 hours of music playback.

Then again the handset was demonstrated to be in Airplane mode, meaning that cellular activity was not present. It was not connected to WiFi either, meaning that there was no data being transferred, so we guess it’s not that surprising that the battery lasted 60 hours. While it hardly constitutes as real-world testing, we guess Qualcomm just wanted to show that at the core, this is how long their batteries can last.

According to Qualcomm, “We used standard Android APIs with Qualcomm Snapdragon enhancements. For supported audio types such as MP3 or AAC, the audio stream is sent to the DSP in large chunks without being decoded on the Android side. This allows the apps processor to sleep while the DSP decodes the audio and sends it to the codec. This results in an enormous power savings while listening to music, since the beefy quad-cores can power down.”
