So you've been using iOS 13 for a little while and noticed your iPhone is pretty slow to charge. Using the 5-watt power adapter out of the box, in the time it used to take your iPhone to charge its battery to 100 percent, your iPhone is stuck at 80% or below instead. That's because Apple introduced a new feature in iOS 13 that slows down charging — but for a good reason.
One odd change found in the Android Pie update is that the "Battery" menu no longer lets you see apps that are draining your battery, nor gives access to usage details. However, one quick menu tweak will bring the Battery menu back in line with Android Oreo's, only there's a hidden setting you have to unlock first.
While the Apple Watch does have up to 18 hours of battery life each day on a full charge, your results will vary depending on how often you use it and what you're actually doing with it.
The old "my battery is dead" excuse for not calling your mother may soon be a thing of the past. A team from the Korea Advanced Institute of Science and Technology (KAIST), led by Professor Jo Byeong-jin, has developed a "wearable thermo-element" that can be built into clothing to power your electronic devices. The science behind the innovation converts body heat (thermal energy) into usable electric energy. Made with lightweight glass fiber, this small thermo-element strip can produce about ...

There are plenty of jokes out there about the battery indicator on iPhones. Some people complain about their iPhones dying randomly at 11%, while others see hours of use at the 1% mark. Despite its inconsistencies, that battery percentage is a useful tell for how desperate you need a charger. There's just one problem: the icon is hiding on your iPhone 11, 11 Pro, or 11 Pro Max.
With iOS 12, Apple is making up for mistakes from the past, with iPhone batteries being no exception. The new update builds upon both battery health and performance throttling tools introduced in iOS 11.3 by offering users more information about your iPhone's battery usage than ever before.
Many modern Android devices use a display technology called AMOLED. These screens differ from traditional LCD displays in that each pixel emits its own light, so a backlight is not required. Even better, when rendering a black element on the screen, AMOLED displays simply don't light up the associated pixels, meaning virtually no power is used. Since black pixels use little to no power on an AMOLED screen, more black pixels means lower battery consumption.
Measuring the voltage of a piece of electrical equipment is a somewhat dangerous and complicated but necessary process if you want to do any sort of DIY electrical projects.

The battery icon in your iPhone's status bar gives you a visual idea of how much power is left, and there's a battery percentage option you can switch to or view in the Control Center, depending on your model. But what you may not know is that there's a way to view the battery percentage of every device connected to your iPhone, from AirPods to Bluetooth speakers and your Apple Watch.
Even with today's high-powered devices, battery life is still an issue. We, as users, have to almost habitually check the current battery percentage, because otherwise, we might end up draining too much in the morning, then get stuck with a dead phone at night.
Smartphones have otherworldly specs these days, so it's relatively uncommon that you hear someone complaining about display resolution, build quality, or general speed and performance. At best, these are secondary concerns, with the number 1 issue almost unilaterally being battery life.

A basic instruction for electronic enthusiasts. I use an RGB LED and a 510 ohm resistor as I may change from 6 to 9 volts later, but with my LEDs i could go as low as 330 ohms. I sacrifice some brightness for the sake of longer life. To choose your resistor, the value in ohms = voltage of your batteries or power supply / (as in divided by) the amperage that your LED needs to run.
