Microsoft thinks they can make your smartphone battery power last all week
If Microsoft has its way, smartphone battery life could last up to a week at some point in the near future. That's the claim from a team member at Microsoft Research who stated this week that longer battery life can be obtained by making some software and design tweaks to current smartphones.
Speaking at the MIT Technology Review's Digital Summit in San Francisco this week, Microsoft researcher Ranveer Chandra pointed out that it has taken 15 years for the density of batteries to double. He says there are other ways to extend battery life right now rather than wait for advances in that technology.
One method that Microsoft has experimented with is putting in two smaller lithium-ion batteries inside a smartphone, rather than one larger battery. The idea is that one of the smaller power packs could be used to generate a larger current when there is an application that needs the extra power, like a game. The other battery could run at a lower current for when the smartphone is in idle mode.
Chandra says that prototypes that have been built with this dual battery design have seen battery life last as much as 50 percent longer compared to the single battery method.
Another method that's being tried out is called E-Loupe. Chandra says this involves installing software on a smartphone that can find apps that are using a lot of battery power, even when they are not being used, and either shut them down or slow their activity.
There's certainly a lot that could be done to increase battery use in smartphones and other mobile devices, and hopefully some of these methods, such as the ones that are being developed by Microsoft, will find their way into the consumer market sooner rather than later. And, of course, there are things like the screen and radios that take up the majority of the juice in day-to-day use — those are still going to need some doing.
What kind of battery life are you getting from your Windows Phone?

Although i liked the idea of putting two Li-ion batteries....
you can buy a cheap feature phone for that. Otherwise you're lugging around a huge touchscreen, camera, etc, etc just to make calls. utter waste.
Moreover, I installed 8.1 on my wife's Lumia 820 which used to get almost a whole day of usage, and now her battery is empty after 6 or 7 hours without almost touching her device!!! This is almost unbearable, it's almost not a mobile device anymore! Microsoft, get your $hit straight and please fix this in the official release!
example... did people have their wifi always on in 8.0 (after amber update or whatever) or they turned on the option off and used it like windows phone 7/8? (you know it turns wifi off when screen is turned off) well then you can't expect much if you are always connected to wifi and they just turn it off. I use it always on in windows phone 8.1 (never used it in 8.0) and still I can get 2 days average battery life.
also, did people change the mail configuration and how it syncs? because 8.1 could change it to always check for emails, so more accounts you have more battery life wasted.
do they stopped every useless background task?
yeah 8.1 needs firmware update to be better, but IN MY CASE, it's better than 8.1. and battery life has improved a little.
But if people install a preview update waiting it to be perfect and with no issues and they don't try to find the way to optimize their battery life, is it 8.1 fault? no.
The truth. Also, you have to take care of your background tasks and accounts syncing setups after updating. I have almost the same battery life as before (except I use my phone a lot more now).
For example, I am using the phone right now and played about 15 minutes of Greed City earlier today. My phone has been off charge for a little over four hours and the battery is currently at 87%.
One thing I don't understand. I see so many articles on tech sites that state that battery development is continiously making huge progress. Why don't we see this technology in our modern smartphones right now?
And that's with 4G, 2 syncing email accounts, Facebook, 6snap, Instagram, etc. all running in the background.
The only progress that has been done is to squeeze in a larger battery in phones, but that's not the best solution. So its good to see a major player working in this direction. And who knows with Lumia devices in future actually resulting in better performance of battery. Claim for a week may be overkill but two days with extensive use might not be that far fetched.
If u can make it last for 4 days, then u run the mobile world.
The same is my new L925. 2 days on mild usage with everything turned on.. And with everything off and baterysafe mode it lasts for 5 days.
I dont get it if anybody needs more.
If you are going to the wildness, buy some solar energy recharging panel ;-)
