steven36 posted a topic in Technology NewsWhich version of the Dell's refreshed XPS 13 with Kaby Lake CPU should you go for? That depends on how much you value your display and battery life. On the Laptop Mag Battery Test, which involves continuous web surfing over Wi-Fi, a model with a a 3200 x 1800 touchscreen display lasted 9 hours and 11 minutes. That's nothing to shake a stick at, as the ultraportable category average is a little over 8 hours. However, the nontouch version of the XPS 13, which has a lower-res 1080p screen lasted a whopping 13:49. That's one of the longest runtimes of any laptop we've tested this year. It should be noted that the touchscreen model featured a Core i7 CPU, as opposed to the nontouch XPS 13's Core i5 processor, but the high resolution and touch options are more likely culprits to be battery suckers during average use. The displays are noticeably different. The 1080p version is great; It covers 94 percent of the sRGB color gamut and reaches 302 nits of brightness, all with great viewing angles. But the QHD+ version, at 105.7 percent of the gamut and 305 nits of brightness, has a higher resolution that looks far more detailed. When I watched the latest trailer for "Wonder Woman," the sky, trees and oceans of Themyscira were more vivid than on the non-touch screen. Unsurprisingly, the Core i7 CPU outperformed the Core i5 on Geekbench, 3DMark Ice Storm Unlimited and other performance tests (read our full review here).

vissha posted a topic in Mobile NewsIs It A Good Idea To Charge Your Smartphone Overnight? Will Charging Your Smartphone Overnight Damage It? Here’s What You Should Know There are chances that many of us plug in our smartphone for charging while going to bed at night, so that you do not have a fully drained device or low battery while rushing to work or travelling, etc. If you think that charging your device overnight is a good idea, you may want to think again. If you plan to upgrade your smartphone every two years, leaving your device to charge overnight will not do much damage to your battery. Experts say majority of the time those people are not going to notice much damage to their smartphone batteries before they start wishing for a new device. However, frequent charging does damage the lithium-ion batteries in our smartphones. And it’s not because they can be overcharged, said Edo Campos, a spokesman for Anker, which produces smartphone chargers. “Smartphones are, in fact, smart,” Mr. Campos said. “They know when to stop charging.” In other words, smartphones are designed to understand when the battery is at capacity, and should at that point stop absorbing additional electrical current. According to a report by The New York Times, Android smartphones and Apple iPhones are equipped with chips that protect them from absorbing excess electrical current once they are fully charged. Theoretically, any damage from charging your smartphone overnight with an official charger, or a trustworthy off-brand charger, should be negligible. The report stated that most smartphones use technology that allows their batteries to charge faster, but this process leads to lithium-ion and lithium-polymer batteries rusting faster. If a user wants to preserve the life of their lithium-ion battery beyond the typical lifetime of a smartphone – usually two years – they can try using a charger made for a less-powerful device, stated the report.

The other day, Microsoft made some bold claims about the power consumption of Edge. The company claimed that its latest web browser is the most battery-friendly when compared to Chrome, Opera and Firefox. Having been beaten into third place behind Chrome, but ahead of Firefox, Opera has hit back. The company says that its own tests show -- surprise, surprise -- that it is Opera which is the most efficient battery sipper. Opera says that its own battery saving feature boosts battery life by up to 50 percent when compared to Chrome. The company criticizes Microsoft for failing to reveal its methodology, accusing it of a lack of transparency. But Opera is guilty of being disingenuous, as it fails to compare like with like. In a post on the Opera blog, Błażej Kaźmierczak says that the company was taken aback by Microsoft's claim. He says that when Opera was being optimized, Edge was ignored: "we didn’t pay attention to was Microsoft Edge, mostly because [it] is only available on Windows 10". He goes on to reveal Opera's own batch of tests that show that far from being the best performing browser, Edge is actually knocked into second place. The graph clearly shows that in Opera's test, Chrome gives 2 hours 54 minutes of battery life, Edge gives 3 hours 12 minutes, and Opera gives five minutes short of four hours. To back up its claims, there's even a video showing the methodology ("Our test (which you can replicate) show..."), and full details of the tests are provided: This looks good for Opera, and bad for Microsoft. Opera throws down the gauntlet, saying: But Opera is not being entirely honest. In its tests, it works with Microsoft Edge (25.10586.0.0) and "the latest version of Google Chrome" (51.0.2704.103). You would expect Opera to offer up the latest version of its own browser to make for a fair test, but no. Instead, what is used is "Opera Developer (39.0.2248.0) with native ad blocker and power saver enabled". So a developer version of Opera -- a version used by a small subsection of the browser's user base -- is pitted against the publicly released versions of Chrome and Edge. That hardly seems fair. Play the game, Opera. Article source
BatteryBar displays relevant information on your laptop's battery, such as full runtime and battery wear. With its help you can keep track on your battery's lifespan and figure out how to take better care of your laptop. The installer includes a BatteryBar toolbar and floating toolbar, and you can select which of these components you want to install (or both). It also offers support for additional themes and language translations. The interface of the tool consists of a very small frame which resembles a battery meter. It shows the current percentage of your remaining battery, but you can hover the mouse cursor over it to get additional details. Therefore, you can find out the current percentage level, capacity, charge rate, status, elapsed time, full runtime and battery wear. The unregistered version does not boast many functions, but you can unlock the pro edition for a limited time, in order to use BatteryBar at its fullest. For example, you can select a battery power scheme, make the frame stay on top of other windows, as well as pick a battery profile to display in a graphical representation, based on the charge or discharge factor. However, the main configuration is done from the Settings panel, as BatteryBar sports numerous options to alter. You can use separate battery profiles for each power scheme, hide the tool when the battery is fully charged, change the font style, and show individual battery status popups for dual batteries. It is also possible to use custom sounds for critical and low battery warnings, automatically close notifications after a particular time frame, adjust the warning levels (based on remaining minutes till discharge), disable the Aero effect, specify a power scheme to automatically switch the laptop to when it's plugged in or on battery mode, as well as log all details and reset all settings and stored battery profiles. BatteryBar is fairly light on the system resources, has a good response time and provides accuracy regarding the battery levels. We have not encountered any problems throughout our evaluation. In conclusion, BatteryBar delivers a simple solution for monitoring the battery status, yet allows plenty of configuration steps for power users.
