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.
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.
I don't know about you, but nothing is more annoying than when my phone hits 15% and I'm nowhere near a charger. Not just because I know my phone will die soon, but until I reach a charger, I have to deal with the annoying low battery notification and LED light. Well, with Android 9.0 Pie, we finally can escape this.
On all other iPhone models, you go to "Battery" in the Settings app and toggle on "Battery Percentage" in order to see the exact amount of power left in the status bar. On the iPhone X, XS, XS Max, and XR, however, that option no longer exists since there's not enough room up there to show the percentage indicator because of the notch for the TrueDepth camera system. But that doesn't mean it's gone entirely.
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.

The iPhone has a feature that lets you see how much juice is left in your Bluetooth headphones, but most Android phones are lacking this ability. Thankfully, there's a simple app that'll close this gap in functionality.
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.
Several Samsung phones have a feature that turns the screen black and white when the battery is getting low. This takes advantage of the AMOLED display in these devices, because unlike red, green, and blue pixels, no battery power is used to display black pixels on this type of screen.
Chinese tech company OPPO has been on the cutting edge of smartphone battery charging since it released its VOOC Flash Charge in 2014. Using VOOC, you can charge your battery from 0-75% in 30 minutes.
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.
Live wallpapers, like the classic Mario-themed one we previously covered, is a great way to spruce up your device and get some simple amusement. Unfortunately, they also drain more battery than conventional wallpapers. Which brings me to ASUS LiveOcean.
How To Install a Battery Float Charger Maintainer On Your ATV
It's hard enough to keep tabs on the battery life of one device, let alone all of the different gadgets that a typical consumer owns in this day and age.
