Is it possible to have 1-week battery life? Microsoft believes so!

by: Edgar CervantesJune 12, 2014

Microsoft’s Ranveer Chandra has taken the stage at MIT Technology Review’s Digital Summit, taking San Francisco’s breath with what could become one of the most important projects regarding battery life. Our current devices force us to plug in every night, with some more unfortunate users having to charge their smartphones multiple times a day. Microsoft aims to change this, throwing around the idea of 1-week battery life.

Today’s main concern in the matter is that smartphones, tablets and other devices are smart about everything but how they use battery power. Gadgets are simply not very resourceful or efficient when eating away all that juice. This is mostly because smartphones are becoming exponentially more powerful by the day, whereas battery technology is essentially staying the same.


Does this mean we need bigger batteries? Do we simply wait for the next battery technology to come around? No, there are many ways in which hardware and software can be optimized for better battery efficiency. We can take LG’s 3A technology as an example, in which the Korean manufacturer slows down display frame rate and processing power when the device doesn’t need it.

How will Microsoft achieve 1-week battery life?

Likewise, Microsoft has a few tricks up its sleeve, and they have chosen to share a few with us. One of the most interesting experiments is one in which instead of having one large battery, two smaller ones are put in place. One battery would handle more powerful processes (such as gaming), while the other would keep the phone with enough juice to take care of background work when idle, for example. Prototypes have proven to increase battery life by 20%-50%, which is a huge step up.

Most other battery-saving techniques do involve software improvements. One of Microsoft’s projects is called E-Loupe, and it monitors resource-demanding apps, slowing them down when the program deems it appropriate. The team has also developed a tool for developers, helping them predict how demanding their app will be. It also helps them easily reduce it.

Is this really possible?

We are not sure if it’s possible, but we don’t expect to see such battery life in a long time. We have seen LG do wonders with the G3. With all its amazing specs and 5.5-inch QHD display, the device still manages to stump over the competition (according to Phone Arena’s tests).

I have personally experiences 2-day battery life with the LG G2 (with light usage) and must say it’s an amazing experience. It’s also the main reason why I miss the LG G2 so much. One week is a long time, though, especially for such complex devices. I see it very hard to accomplish in the near future.

    It’s all about software optimization.

    My Cowon and Speelr MP3 players easily outlast my Androids doing the exact same things – playing MP3s with all connections (bluetooth, WIFI and LTE) off and with the screen off. The difference is obviously background tasks.

    With Microsoft, the OEMs leave the software optimization to Microsoft (who, according to this article, is obviously working on that) whereas in Android it’s between Google and the OEMs. Samsung, for example, doesn’t seem to be concerned one bit with software optimization and use “better hardware” as a solution to every problem. It’s great for innovation, but the result of this research and development increases hardware competition and trickles down to smaller OEMs that buy from Samsung… but… if it were my company, which it obviously isn’t, they would also have to care about software optimization.

    Looking at the big picture, however… it’s good that Samsung is going about this all wrong with Touchwiz… despite that serious handicap, they’re still crushing the (Android) competition… Samsung with better software (and maybe better design) would seriously kill the competition.

    From a consumer perspective, between Samsung and the likes working on improved batteries on one hand and Microsoft and others working on improving software’s battery usage, it’s a good thing… even though if all these innovations materialize, the phone to benefit the most would be Samsung’s Windows Phone… which means I’d (eventually) lose a serious bet I made at the office.

    Battery life can last a week if the software is built to do so. However, it is a combination of both hardware and software. We need more energy efficient hardware in combination with better optimized software. How we are going to go about doing this, I do not really know.

    You can easily have months of battery life in m$ phone. Just turn that crap off and use android !

    Lol I was thinking they were going to make the battery last for a week running intensive program like games non stop. For example running application like 3dmark for a straight week on a single charge.

    we need to find those Energon cubes

    I HAD 1 week battery life with my Nokia 6300.
