How often have you have thought of acquiring the power of monitoring your cellphone’s battery? Well, for most phones it would be just a dream, but thanks to openness of Android, it’s truly transparent.

The App is called PowerTutor, it does provide insight as to what’s using the most juice out of the battery – Is it the display, or CPU usage on an App, and even breakdown of power usage by apps.

No doubt, it’s far more superior than Android’s native power monitor, and in fact most advance app that ever landed on a Phone. The native Android monitor is limited to the percentage of battery use by component or application.

PowerTutor goes down into detail and draws a graph to represent the actual power .. Read Further »

Windows 7 Kills Battery

When I first migrated to Windows 7 in it’s early BETA days, I was all too excited by the new stability, UI, features and quoted Battery life improvement. But, all this came with a bad [practical] news: I saw serious reduction in battery life.

The battery backup reduced from 2.5hrs to merely 1hr. I believed this was due to the the heavy Nvidia GT m230 GPU (Windows 7 doesn’t support NVIDIA Powermizer which reduces battery usage by lowering the clock). But very soon, all other Operating Systems started to mimic .. Read Further »

We may have been to Moon and back, but we still use those pencil size AA batteries which have poor life and are large in size.

Cost of manufacture of these batteries is estimated to be several billion $s every year, and the environment pollution caused is almost irreversible.

To counter this problem, conducting polymers have long been thought to be a solution in developing lightweight, flexible, nonmetal batteries. But up until now, these polymers have had been impractical because regular paper can’t hold enough of them work effectively.

Thanks to the new research by ppsala researcher Maria Stromme and her team surrounding the use of Cladophora (green algae) in a flexible, ultrathin alternative, it looks as if we may finally be onto a good Green Technology. Researchers purport that these super skinny cells could be placed in areas where .. Read Further »

Windows 7 RTM Review showed us how well it is when it comes to Performing as compared to Vista, XP.
We were happy there. But there’s one more thing with windows 7 that will delight users switching from Vista — 25% improvement in Battery life.

Ruston Panabaker, Microsoft’s principal program manager of strategic silicon partnering, shows how later builds of Windows 7 were able to let the processor enter low-power states for longer periods of time, saving more power.

Microsoft themselves showed us Live test to prove Vista is crap — Two identical laptops playing the same DVD, with the Windows 7-equipped notebook getting 20 percent better battery life than one running Windows Vista. In general, users can expect newer systems running Windows 7 to offer 10 percent to 20 percent .. Read Further »

Are Sealed batteries, like Mac book Pro, any better?

admin — Sat, 27 Jun 2009 17:44:20 +0000

Today, the most of the laptops come with removable batteries. This gives you flexibility to put in a fresh one when your original battery runs out of juice. But few manufacturers, like Apple, like to ship sealed ones.

Every Lithium-ion battery (standard for mobiles, laptops) have life of few charge-discharge cycles. Ideally its 360 full charges. That means you battery can be full dsicharged 360 times before it dies, On average this results in average life span of 2 years. Earlier I posted “Secrets of Prolonging Life of Lithitum Ion battery“. In this one, Let’s discuss why are sealed batteries better.

Why Sealed Battery?

Due to the chemistry involved, sealed batteries usually have an open-circuit voltage of 13.1 to 13.2 .. Read Further »

Convert a Gadget From Money-Sucking Batteries to AC Power.

Every one knows the constant cycle of buying or recharging batteries for kid-related products—but the Instructables web site has some guides to modifying your gadgets to use AC power instead of batteries.

The guides walk you through the process of converting your battery-sucking gadgets to use AC power. Both guides require rolling up your sleeves, ripping the gadget apart, and doing some soldering—if using a soldering iron is new to you, LiffeHacker’ve got a beginner’s guide to help you out.

The first guide covers in detail how to use a switch, some wire, and an old cell phone charger to convert a baby swing to use AC power, and the second guide is a more broad, general overview of how to modify devices—but isn’t quite as detailed. If you’ve got any personal experience in modifying gadgets to use AC power instead of batteries. .. Read Further »
