Want a long-lasting smartphone battery? Microsoft is working on it


Although smartphones are becoming more advanced faster than we’d previously imagined (going from 720p to Quad HD screens in just a few years is almost unbelievable), there’s still one thing that seems to always disappoint: battery life. You see, battery technology hasn’t really changed in recent years. And it may not change much in the coming years, either. Knowing this, Microsoft is working on providing longer battery life for mobile devices by using current technologies in a smart way.

Ranveer Chandra, Senior Researcher in the Mobility & Networking Research Group at Microsoft Research, recently revealed a few of the ideas that Microsoft might use to extend battery life. According to MIT Technology Review, one of the ideas is to develop devices that use two smaller Li-Ion batteries instead of a single large one. One of the batteries would provide the juice needed for power-hungry activities (like gaming), while the other one would be in charge of regular tasks, including the device’s idle state. Apparently, Microsoft has prototypes using this idea, and these can improve battery life by 20 to 50 percent.

Hardware aside, Microsoft is also looking at ways to use software optimization in order to increase battery life. The company developed an “E-Loupe” software prototype that can identify apps which draw a lot of power when not needed (like when they run in the background), and pause or slow down their activity.

Some Android smartphones (like Samsung’s Galaxy S5 and HTC’s One M8) are already using software tricks that help them offer a longer battery life.

Microsoft didn’t say when it's planning to make its ideas ready for commercial use, but we hope to hear more on this soon.

As if our phone has enough SAR already

They just need to get the charging down to under a minute. That was mention last year. Someone was working on a battery that could be fully charged in less then a minute. If they can make a battery like that. Then I would not care if the battery life stayed the same.

I'm not sure about that two-battery concept. I just don't see how it would improve battery life...

One is optimized for high current draw and the other, for low. This way, the resulting charge form both together (depending on the duty cycle) may be greater than of one high-current battery.

Oh okay, now it makes sense. The article didn't explain how it works...

I don't think it is the good explanation. It is more like a first battery that will only be used by a low power CPU or and applications and that can last very long. When the user opens a new application that is power hungry, the second battery will be activated, whereas the first will be "deactivated". When the second has no more energy, I guess the app will close and will be blocked, but you will still be able to call and send text messages with the low power battery that is supposed to last very long. This idea is good and reminds me of the 8 core Exynos processor.

Longer battery life is always welcome. Thats one of my biggest grips about so called smartphones. So smart yet simple thing like battery life they can't sustain for a prolonged period of time. More practical features less gimmicks is what I appreciate.

From my experience, the S5, M8, Note 3 and G2 have supurb battery life.

Does last a week without charge? Hahaha don't think so

I don't know about you, but I'm never away from an outlet that long. I'd be more than satisfied with 36 hours of heavy usage. That way, if for some reason I can't charge my phone one night, it will still last til the following night.

and my car doesn't go a month without needing Gas. lets be realistic about batteries. One day is currently excellent battery life.. one week is fairy land.

Kind of depends on what you consider to be supurb..

Papa Smurf, please try the Xperia Z2, activate Stamina Mode and then tell me something ;) That 3200mah is worth something ;)

UPSM and HTC's Power Mode from what I've seen last longer than the Z2's.

I am going to guess that you only know what "superb" means based on how well you can spell it.

Hearing about different battery technologies for years now. But no actual product. Only news.

how about making good battery life on surface :)

How about increasing the Mah and adding extra millimetres to gain extra 500+Mah.

That's a good start. Finally, someone who starts to put effort into physical change of batteries to improve the life. Hopefully it does, and other manufactures follow along so everyone can get excellent battery life.

3rd paragraph 2nd line its supposed to be better not batter

Read again it should be battery not better.

Does it include a blue smoke screen of death?

This is why Android Fans are low people. Never appreciate other companies other than Google. Wow

So do you. Look at your avatar. :) I don't like when you said that Android fans are low people.

Well all I can say is. Android fans trolls sure ruined this website identity. And also what does my avatar have to do with anything

After seeing such low wp fan avatar. I am glad they are the minority. Last to get anything remotely useful. I don't use WP because they are the under privileged and always a 'me too' company. I am train in their corporate tech however.

Actually this feature reinvented from Apple in IOS 7 with the blue screens and random reboots.

what if the phone used all the juice in the battery for power-hungry activities? So, I couldn't use my phone for power-hungry activities anymore though I still have the juiced left in the other one?
