"Wireless Charging" Make iPhone Batteries "Leaking"?

One of the new features (for iPhone) presented by iPhone 8, iPhone 8 Plus, and iPhone X is the ability of wireless battery charging, aka wireless charging. Although practical because it can charge the device without the battery must be connected to the cable, wireless charging may bring bad effects to the iPhone battery.

This was revealed by an owner of the iPhone 8 Plus named Adrian Kingsley-Hughes who suspected that the performance of the phone is getting more and more decreased after he started using a wireless charger. Adrian then installed the CoconutBattery app to monitor his iPhone 8 Plus recharge cyle.

Recharge cycle is the battery charging cycle from 0 to 100 percent and valid cumulative. For example, users use 75 percent of the phone's battery up to 25 percent left, then fill up to 100 percent the night. If the next day the battery is used 25 percent, it will be counted as one charging cycle.

The iPhone battery is designed to be capable of saving 80 percent of its initial capacity in 500 times the recharge cycle, typically achieved within 2 to 3 years. However, from CoconutBattery, Adrian learned that his iPhone 8 Plus has undergone 135 recharge cycles in less than 6 months.

Counting 'Wh' Powerbank Tips Allowed to Enter the Aircraft

Ministry of Transportation (Kemenhub) some time ago announced a new regulation related luggage in the form of power bank into the cabin aircraft. In a circular that has a date of March 9, 2018, Kemenhub set the amount of powerbank that can be brought into the cabin, which is 160Wh.

Actually, the rating from Wh which has been determined by Kemenhub is at the back of the power bank device. But not infrequently also the power bank producers do not list how big Wh is in their device.

On this occasion, Okezone helps you to find out if your power bank can be taken up into the cabin of an airplane or not. How to calculate it is quite easy.

First of all, find out how much mAh is from your powerbank. For example, a powerbank with a battery capacity of 10,000 mAh.

After that, look for the voltage rating of your powerbank. Typically, a powerbank is present in a voltage rating of 3.8V or 5V. Suppose that your powerbank shows a 5V rating.

After getting this data, you just put it in the formula. However, before entering the formula, we must first convert the mAh unit to Ah, by dividing it by 1,000 (from Mega Ampere to Ampere).

Kickstarter Create Accessory Change Digital Camera to Analog

While many photographers are praising the virtues of analogue and movies, they are able to produce 'warmer' images and have certain tones or nuances that digital can not be imitated. So it's hard to ignore some of the drawbacks in shooting with movies.

One is the inability to check photos after taking them. You should spend some time and spend money developing movies. In addition, storage capacity is also low.

However, the Kickstarter campaign for an accessory called 'I'm Back' has been launched. This tool is for your analog SLR camera that will turn it into a hybrid digital camera.

This accessory comes with a 2-inch touchscreen and also provides analogue WiFi camera capabilities, to allow users to transfer photos. I'm Back is also equipped with Panasonic 16MP sensor and image processor Novatek 96660. Basically it's kind of 'hijack' the analog camera to take advantage of the lens, while the shots taken to digital.
