Nicad batteries often die in such a way that they won't take a charge and have zero voltage. This usually means they're shorted out by crystal dendrite growth. Here's a method of bringing them back to life by zapping those shorted crystal dendrites away with too much current and/or voltage. We'll use a welder as a power source. You could also use a car battery, a DC powersupply, or almost anything with some voltage. Charged-up capacitors are popular for this because you can get a very fast pu...

Another year, another battle between Samsung and Apple. We recently saw what Samsung is bringing to the table this year with the release of the Galaxy Note 10+, and now it's Apple's turn. For those who want a truly large device, Apple is offering the iPhone 11 Pro Max. Let's see how they match up.
The ongoing war between Apple and Samsung fans will rage on once again. With the release of the iPhone XS Max, Apple has presented a stronger adversary for the Samsung Galaxy Note 9, released earlier. Both stack up well against each other, providing two of the best experiences on their respective operating systems.
The LG V30 has solid battery life. With its QHD P-OLED screen and 4 GB RAM, it's able to maintain all-day performance with average use. Heavier users might find that its 3,300 mAh battery isn't quite enough for a full day of work, though, but with a few software tweaks, you can squeeze out even more battery life.
The Note 7 debacle taught Samsung an important lesson on cramming oversized batteries into their handsets, and they've applied it diligently to their Galaxy S8 and S8+. You might even say the company has gone a little too far in trying to achieve a balance between battery size and battery life, as it not only not only sets screen resolutions to 1080p by default and warns users about maxing out display brightness, but it also keeps close tabs on individual apps' battery usage.
The Samsung Galaxy S8+ isn't yet available for consumers to buy, but that isn't stopping tech reviewers from discovering what the phone is capable of. Turns out, the S8+ has a good battery—just not as good as the iPhone 7 Plus.
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.
Android's stock battery menu is pretty decent. You can see which apps have been using the most power, and you can tell when your CPU was awake or asleep, among other things. But a lot of times, battery-sucking services will get lumped under the generic "Android System" header, and even though you can see when your CPU was awake, you can't exactly see why.
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.

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.
Many Android games use large, storage-heavy OBB files to store supplemental data. Generally, games with high-end graphics download these extra files when you install them from the Google Play Store.
