Battery life remains to be one of the major concerns of smartphone users today. That is why Microsoft Research are finding ways to remedy this problem. According to Ranveer Chandra, their team is exploring the possibility of creating smartphones with batteries that can last for seven days without the need to use external battery packs.
One method is to put two li-ion batteries in the phone instead of one. These batteries can split usage depending on what the users need. For example, one can provide larger supply for heavy use and the other can be for standby mode. They are also exploring software optimization through a process called E-Loupe. This will pinpoint battery hungry apps that the software can slow down or pause when not in use. The research team has been able to create prototypes that improved battery life from 20% to 50%. It’s not yet their goal but we’d take that over a lot smartphone batteries we have today.
