battery life

Thanks to the Preview for Developers program we’ve been playing with Windows Phone 8.1 for more than three days. It’s been very well received by most everyone in the community. Now it’s time to check out how your battery is doing after upgrading from Windows Phone 8.0 to Windows Phone 8.1. Has your battery life improved or taken a turn for the worst? Maybe is it just the same as it was before. Let’s find out.

Microsoft Research is looking into white space frequencies, that we already know from an exploration venture kicked off by UK telecommunication regulator Ofcom. So what exactly are white spaces? Just in case you're confused thus far, they're essentially parts of the frequency band that aren't actively being used by digital TV or wireless systems. Making use of airwaves that are currently unused would open up new possibilities for a number of applications, which participating organisations are collaborating to work towards perfecting.

An important factor for laptops, tablets and other mobile hardware is battery life. After Microsoft released the Surface Pro 2, the company pushed out a firmware update enabling the WiFi to go into lower power states and utilise even less power. AnandTech has run another battery life benchmark for the product after updating to see just how much of an improvement we're looking at.

We heard and experienced for ourselves some rather crummy battery life with the Nokia Lumia 920 Windows Phone. It's a mixed bag of results with some report fantastic battery performance while others are struggling to make it through half a day.

While Nokia is looking into things, they've reminded us that managing the apps that are running in the background could help with battery life.  And this power saving technique isn't exclusive to the Lumia Windows Phones.  If you want to conserve power on your HTC 8X or Samsung Focus 2, shut down some of the apps you don't need that are still running in the background.

Yesterday, we mentioned that several readers were having terrible battery life with their Nokia Lumia 920 Windows Phone. Some batteries barely lasted half a day while others steamed on with fantastic battery life.

We had a few suggestions to disable the NFC to improve battery performance. Yesterday, with NFC enabled, my Lumia 920's battery only lasted six hours before drying up.  The 920 also got warm throughout the morning. Today, after disabling the NFC the Lumia had 62% battery life remaining after ten hours and I didn't experience any warm spells.

There's a discussion going on over at the Windows Phone Central forums that has us a little concerned about the Lumia 920's battery performance. Some are seeing their batteries being sucked dry in a few hours while some aren't seeing any issues.

Our Dan Rubino refers to his 920's battery life as fantastic and I would have agreed up until today when my 920 barely made it six hours on a full charge.  Oddly the back of my Lumia 920 became warm during throughout the morning.  Made for a great hand warmer but I'd trade cold hands for better battery life any day.

When the Nokia Lumia 920 specifications hit last month, the rather large battery (2000mAh) was touted as one of the main features, resulting in supposed “all day use”. That’s especially important for consumers on such a powerhouse of a phone since it has all of those bells and whistles on board.

The AT&T version has recently been posted on Nokia’s site and it has some updated specifications from the global version, including some new battery times. The bad news is they have been slightly marked down for the massive 4G network, most likely due to some carrier requirements resulting in some firmware changes in addition to that super fast LTE network.

There's a discussion going on in the WPCentral Discussions Forums about the Nokia Lumia 900's battery life. It appears that some Lumia 900 owners aren't experiencing the greatest of battery life from their new Windows Phone.

Tweetwp7 reports that their HTC Titan's battery would be around the 60% level at the end of the day while the Lumia 900 is at 45%. Red Grenadine, on the other hand, reports fantastic battery life.

Personally, I had stellar battery life on my Lumia 900 for the first five days and that's with heavy use trying to compare the Lumia 900 with the HTC Titan II. Then the other day the connectivity issues struck and my battery life dropped like a rock. I'm seeing about 40% left after eight hours of use where the Titan II is in the 55-60% range.  In the time it took to write this article (about twenty minutes) I saw the Lumia 900's battery drop 3%.

In checking out the battery performance using Nokia's Diagnostic Tools (you can install them by dialing ##634#) my battery discharge rate ranges from 100mA to 500mA while the Lumia 900 is sitting idle (no wifi, BT, no live tiles, no apps running in the background, etc). Now I'm no electrical engineer but that doesn't seem right.

There could be a direct correlation between the connectivity issues and the battery drain or it could be a separate issue all together. We'll have to wait and see when the fix rolls out in the next few days to see if the battery performance improves as well as the data connections.  Our fingers will be crossed that it does the trick.

If you've seen a change in your battery performance on the Lumia 900, feel free to sound off in the comments or over in this WPCentral Forums discussion.

Thanks, everyone, for the tip!

Help Extend WP7 battery life [How To]

Smartphones have always had the label of "battery eaters" when compared to a regular mobile phone. A good number of years back, a Nokia 3210 would last for an entire year (although we still believe they were secretly powered by miniature nuclear reactors). Windows Phone 7 is not exempt from this battery life issue for majority of owners, but there are ways to tackle the problem and preserve some battery - at the loss of some functionality.

People were pretty excited when the Dark Forces Team successfully ported WP7 over to the HD2, but it wasn't without its bugs. One of the more annoying of them was that the battery level indicator was inaccurate. Tired of the lies, XDA member, arkatis, decided to do something about it. He has posted a registry hack that seems to resolve the issue.  Here's the quick and dirty on how to do it:

1) Charge your phone until the green light shows up
2) Unplug it from A/C and open registry editor
3) Go to the reg path
4) Edit the value from 6 to 20…press ok..Now you will see the battery indicator level has been changed! Again go and edit the value and from 20 go to 80..press ok! Restart and enjoy!

If you want to read the full post with feedback, you can check it out here.

All right, folks. We've got three carriers, er, carrying the HTC Touch Pro 2, and we've got a few weeks of use under our belts. So, let's talk about battery life. The TP2 has a 1500mAh battery, which certainly is respectable. But as Malatesta noted in his review of the Sprint Touch Pro 2, different carriers have different estimates when it comes to battery life. And we all know how these "estimates" go anyway.

And, so, we put it to you, Touch Pro 2 users. Yeah, this isn't going to be very scientific. We all use our phones in different ways. Mal found the battery to be acceptable. Others, including vin5cent0 in our forums, have found it lacking. Chime in and let us know how your Touch Pro 2 battery's holding up.
