Windows 8.1 battery life remaining,rechargeable battery industry ltd,car battery terminal repair disk - Reviews

The PC-versus-Mac controversy took new life last week thanks to Jeff Atwood, who runs the Coding Horror blog. Using the 15-inch MacBook Pro, in 2008 Shimpi discovered that the laptopa€™s battery life varied dramatically when running three different operating systems on top of the same hardware.
Our interest piqued by Atwooda€™s blog post, we ran our own battery tests of different operating systems running on a single piece of hardware: In this case, the 2012 Ivy Bridge-based 13-inch MacBook Pro. We then charged up the Air to full capacity and performed our standard Wi-Fi battery rundown test for each of the three systems, each time accessing a series of websites until the notebook conked out.
The results were telling: The MacBook Pro running Mac OS X Mavericks lasted just over 7 hours. Aul told us that Applea€™s Boot Camp provides a thin layer of code between the operating system and the Mac hardware itself, along with drivers to access the Maca€™s hardware.
For example, a Wi-Fi radioa€™s default driver setting may be set to maximum power to deliver the best throughput at maximum range.
Hardware makers like Asus, Dell, and Lenovo spend a great deal of money tuning drivers and creating an optimized profile that trades some performance for battery life, Aul said. Windows runs a herd of background processes, some of which poll either the Internet, the CPU, or the disk for information or updates. That means Windows spends a great deal of effort trying to avoid spinning up the disk or touching the CPU for system activities, such as indexing the disk.
It is possible, however, that a few poorly tuned, third-party applications may contribute to a decline in battery life, Aul said. Aul also suggested that if PCWorld created a so-called a€?Hackintosha€?a€”a Mac cobbled together and programmed with the Mac OS, and also Windowsa€”such an untuned configuration would favor Windows.
Arguably, running Windows on a Mac, or the Mac OS on a PC, are absurd tests that arena€™t going to give you clear answers on anything. In Windows, the simplest way is to click the small battery icon in the Windows system tray. As PCWorld's senior editor, Mark focuses on Microsoft news and chip technology, among other beats. PCWorld helps you navigate the PC ecosystem to find the products you want and the advice you need to get the job done. Battery life is key for notebooks, and Windows 10 offers a new Battery Saver feature meant to improve endurance.
Battery Saver is a new Windows 10 feature that popped up in earlier builds of the Technical Preview, but wasn’t functional until the January build.
If you’re wondering whether reducing the power usage of apps running in the background will have any effect, take a look at how much they consume in the first place. On the Yoga Pro 2 we used for testing, the screen consumed nearly 11 percent of battery life. We performed an idle time test to compare the battery usage of Windows 8.1 to Windows 10 on a dual booting Lenovo Yoga Pro 2.
Windows 8.1 clearly outperforms Windows 10 Technical Preview, even with Battery Saver turned on.
Windows 10 contains additional Energy Saver settings under advanced power settings, the Control Panel equivalent of Battery Saver in the Settings app. We performed this test under similar conditions as described above, except that we left the screen, the keyboard backlight, and Wi-Fi on for the entire test. Microsoft is asking us to rethink our opinion of Internet Explorer in its latest marketing blitz, and those with a Windows 8.1 device have been given further food for thought on which browser to use.
Internet Explorer has been named the browser that will squeeze the most life out of your Windows 8.1 laptop or tablet battery in a head-to-head study. Windows tutorials website 7 Tutorials compared the four main browsers -- Internet Explorer 11, Firefox 26, Chrome 32 and Opera 18 -- on an old laptop, a new tablet, and a powerful hybrid device, all with Windows 8.1 installed. Using the Peacekeeper Battery Test for its browser battle, 7 Tutorials discovered that Internet Explorer 11 uses the least battery power on all devices.
On the Toshiba Encore 8" Tablet, which has an Intel Atom processor, the best browser for saving battery power is the touch version of IE providing 8 hours and 52 minutes of battery performance.
However, it was the desktop version of IE11 that delivered the best results on the Microsoft Surface Pro 2, lasting four hours and 45 minutes, that's 27 percent better than Chrome. Although IE 11 (desktop version) again managed to deliver the longest battery time on the HP Pavilion dv7 with one hour and 25 minutes, the touch version actually performed the worst by managing just one hour and 13 minutes. In this article, we are providing with the ultimate collection of tips & tricks on how to get the best possible performance and Battery life out of your Lumia (Windows Phone) devices. Following these tips, one could easily improve the Battery life by nearly 5-10 hrs on average. Background tasks enhancement in Windows Phone 8.1 has made more tasks running in Background possible. You can set Cortana and other apps to a€?not running in backgrounda€? when a€?Battery Savera€? kicks in.
You can also set whether you want to play sound for Key press, camera shutter and System alerts. Close all the apps actively running in the background, if you don’t plan to use your phone for sometime, otherwise apps like Map, Drive keep on running in background and kill the Battery.
If you have many mail accounts syncing on your phone, you can kill the battery really fast.
These tips should help in prolonging battery life on your Windows Phone 8.1 running device. Microsoft today morning pushed Windows 10 Mobile Build 14379 to Windows Insiders in Fast Ring. Few months back, I purchased new windows 8 laptop and it was running 8 to 9 hours once I get it full charged. The default power plan of every laptop is balanced but it does provide many other power plans. Give your power plan a name and it will also let you choose default settings of any existing power plan.
Your laptop’s display eats up battery most than any other components do, so make sure you set brightness of your laptop as low as possible. When you are not using your laptop even for long period of time, your laptop automatically dims display and also turn it off.
If you often went away keeping your laptop on than this tip will surely increase battery life of your laptop by 30%.
Your laptop battery powers each and every component of your laptop and yes it also includes USB slots and DVD drives.

There are many people who don’t pay attention to bluetooth and Wi-Fi settings in their laptop. Enabling automatic changing wallpaper and screensaver may sound normal to you but it runs as a whole new process and it is executed by your processor every time your laptop reaches time limit.
We download lots of apps daily from windows store but we never care of its background running. If you think that your laptop battery is not performing well than you can change battery of your laptop.

And at some point, someone will probably bring up the old battery life chestnut: Windows laptops simply run out of juice when you need them most, while MacBooks just keep chugging away. Atwood examined data supplied by Anand Lal Shimpi of AnandTech, ran some tests of his own, and then came to some alarming conclusions. Looking at the Surface Pro he owned and the Surface Pro 2 he had on order, Atwood saw that the expected battery life of the new Surface Pro 2 was just a third better than the previous generationa€™s, at about 6.6 hours. Thata€™s about 2 hoursa€”or about 29 percenta€”longerA than it did when running Windows 7, which pooped out at just over 5 hours. Each driver is a bit of code that controls individual components, such as the Wi-Fi radio or the laptopa€™s display.
Microsoft, in fact, released a firmware update last Friday for the Surface Pro 2 that significantly improves how the OS interacts with the Intel Haswell processor, improving battery life, he said. As I write this, for example, my PC is running eight applicationsa€”plus 118 background processes. But if a user is calling up a photo or an application, Windows will piggyback on the request and accomplish a few key tasks. There, the problem would be reversed: The Mac OS would be a€?unawarea€? of the hardware, and not properly tuned. This will bring up a snapshot of the remaining battery charge, by capacity and estimated runtime.
Haswell machines offer a mix of power efficiency and performance, and the Bay Trail Atom (Atom Z37xx series) allows everything from basic Web browsing to moderate gaming. We have also noted that we used the Windows Power Saver power profile on our Windows tests.
We compared Windows 8.1 to Windows 10 Technical Preview to find out which one presently offers better battery life.
To open it, press Windows + I, which will launch the Settings app, and go to System > Battery saver.
You can turn it on manually or click Battery saver settings to control its automatic activation.
Return to the overview and click on Battery usage to see what’s consuming the most energy. Over 98 percent of power used by software went to foreground applications, which in our case was mostly the Chrome browser. On the other hand, this data suggests that closing background processes won’t have much impact on battery life in Windows 10. To ensure that both operating systems use the devices under comparable conditions, we configured the system to start with Microsoft services only. The display was set to turn off after 1 minute and was turned on at the lowest brightness for around 65 seconds every half hour for a battery level check.
What’s more interesting is how power efficient your system is under usage conditions. We also set an artificially high critical battery level to force Windows to shut down and terminate the test. It will be interesting to see whether the tides turn with the final release of Windows 10, when all this code collecting telemetry data will be gone. Which version of IE 11 delivers the best performance depends on your device's hardware configuration and how well the browser works with it, says 7 Tutorials. This offered 13 percent more battery life than the desktop version of IE 11 and 30 percent more than Opera 18. Android Nougat!Let there be light: Why visibility is key to building an effective mobile policyDeclare independence from Windows 10 by downloading Linux Mint 18 'Sarah' now! This is based on our continuous use of many Lumia devices running Windows Phone 8.1 with both Lumia Cyan and Lumia Denim firmwares.
This allows you to bring the Glance screen live by waving your hand over the device, when needed.
This is a big Battery killer and more the number of background active apps, faster your battery dies.
Windows Phone 8.1 comes with ability to always allow apps to run in background (always allowed), even when the a€?Battery Savera€? is on. Here you can control for which apps you need notifications and you can also manage sounds for push notifications. You can long press on back button to go to the Multitasking UI and either tap on X to the close the apps or simply swipe down.
Keep in mind one or more of above tips may be what you need for your device and thus all are important. So, do let us know, whether you found these tips useful and share if you have any Battery life tip of yours!!
And you can save these settings as a profile so that you can easily and quickly switch it over when needed in the future.The first thing you need to do once you have it installed on your computer is to Run Diagnostic from the Diagnostic tab to let the tool to get know better of your computer system and setup. You can change setting of each of them as per your needs and increase battery life of your windows 8 or 8.1 laptop.
If you are using your laptop in dark places than you should reduce brightness of your laptop as it is good for laptop’s battery and your eyes too. Well you can shorten the display dim and turn off time and get more squeeze more power from your battery. If you keep CD or DVD in drive than it keeps on reading it and eventually you are loosing battery unnecessarily.

Let me explain first what actually happens behind the scenes when you hibernate your laptop and put your laptop in standby mode.
Your processor needs power to show you screensaver and change background images so you should turn this feature off to get most out of your windows laptop battery. Background running of apps is a good feature but along with that it is a big battery eater. Preventing this scenario has quietly emerged as the most significant design trend in mobile computing.
In fact, Shimpia€™s tests showed that the MacBook Pro lasted almost 2 hours longer under OS X. We used Internet Explorer 10 for Windows 7, IE 11 for Windows 8.1, and Safari for the Mac OS, opting for each systema€™s default, stock browser. And even worse for Windows users, our data indicates that a€?upgradinga€? to Windows 8.1 is really a downgrade in battery life, as the new system expired at just 4 hours and 41 minutes. And according to Aul, the basic Boot Camp installation uses a mixture of generic drivers and unoptimized drivers. And when a PC constantly powers on the Wi-Fi radio to download websites, those small differences can add up. Apple is ahead on this game, but Windows users have some options for configuring their power settings, either through utilities provided by the computer manufacturer or via Windows itself. In the advanced settings, you have the option of limiting the available CPU speed and even controlling the fan.
The results are surprising — and show that Microsoft still has a fair bit of work to do. Here you can set a checkmark to turn Battery Saver on automatically if your battery falls below a custom level.
You can view data for the battery use of your system, screen, and Wi-Fi from the past week, past two days, and past 24 hours.
At the time this screenshot was taken, barely 2 percent of battery life was spent on background activity over the past week, but for the last 24 hours of our testing that number jumped to 8 percent. Nevertheless, knowing what takes the biggest toll on your battery level can help you reduce its impact and increase your battery life overall.
We’d like to see more refined data in the future, such as a list of apps and their energy usage, information already available on Windows Phone and Android devices. During the first run we left Battery Saver enabled with the trigger charge level at 20 percent. In case you have tried everything and are still facing issues with Battery life, try a soft reset or even if that doesn’t work try a hard reset.
This is what happens with every laptop, It performs well in initial times but afterwards it starts showing its true colors! The same thing applies to USB devices so one should have a good habit of disconnecting devices which are not in use. It not only saves battery of your laptop but it also secures you from people accessing your laptop remotely over the web! When you put your laptop into standby mode, your opened programs are still live in your RAM so RAM of your laptop keeps eating battery of your laptop.
If you know any other tips which can play vital role in increasing battery life than feel free to share it with me in comments. Smartphones like the Galaxy Note 3, LG G2, and Moto X have prioritized battery life, while power-sipping chips, like Intela€™s Haswell and Bay Trail Atom, now inhabit PCs that offer all-day computinga€”especially when paired with keyboards or covers with supplemental batteries inside. AnandTech had also published battery-life tests indicating that the 11-inch MacBook Air lasted over 11 hours during Wi-Fi Web-surfing tests. For instance, a laptopa€™s display and backlight can consume 20 to 25 percent of the typical power within a PC, so telling the laptop to shut them down automatically within a few minutes of inactivity can extend battery life a bit.
And if youa€™re willing to fork over some additional cash, solid-state drives (SSDs) offer faster access times and lower power demands. I like the update to it is un workable if in present condition,” one user explained the issue on the forums. Another graph shows you the percentage of applications running in the foreground and background. Originally a tool to test browser performance, Peacekeeper also contains a simple battery test, which loops its browser tests until your battery runs out and the computer shuts down.
For Windows 10 Technical Preview, we measured energy efficiency with Battery Saver activated during the entire test. It will automatically turn of and off certain hardware like Wi-Fi, Bluetooth, Infrared, and any external peripherals, as well as adjusting screen brightness. I was worried about this but after tweaking a bit with my laptops settings, I am now finally squeezing more juice out of my laptops battery. Now when you hibernate your laptop, all your programs which are loaded in RAM are saved to local hard drive of your laptop and your laptop shutdowns. There you can stop slideshow of wallpapers or you can stop it while you are using battery as a power source.
At Microsofta€™s request, we also installed Flash on Safari to ensure that any webpages were rendered completely.
Extrapolated to 100 percent, you might get around 8 minutes more battery life out of a Lenovo Yoga Pro 2 running Windows 8.1 than Windows 10. Just follow simple below given guidelines and you will surely notice increase in battery life of your windows 8 or 8.1 laptop or tablets.
In this way hibernating your laptop can help you to increase battery life on your windows 8 or 8.1 laptop. It can be set to automatically alert you when the batter usage increases or drops in a certain percentage.Battery Optimizer works on all major Windows systems, from XP and above, both 32-bit and 64-bit editions. It requires a very minimum hardware requirement and runs in a fairly small footprint in your system.VerdictIn most cases, the built-in Battery Optimizer, aka Power Options, should be sufficient to get your batter in the right place.
