The faster it charges and longer it lasts, the better user experience it can provide. This has been the case for years and isn’t likely to change. What has changed in the last few years is the charging speed. Today, a decent smartphone can get juiced up from 0-100 percent in about an hour, a feat that previously took multiple hours to achieve. This improvement has come courtesy of developments in battery charging technology. While most smartphones about a decade ago offered 5W or 10W charging, there’s one today, called Realme GT5, that can get charged from 0-100 percent in a matter of just 12 minutes! Want to know your smartphone charging speed? There’s an app for it - Ampere app. ## Ampere app: What is it? Developed by Brain_trapp, Ampere is an app that measures the charging speed of your smartphone, as well as its discharging current. Measuring the electrical flow of the battery can help you get to know the general health of the device's battery, watch your device’s power consumption, and find power-hungry apps. Ampere states that while the readings from the app aren’t concrete science, it is a good enough relative measure of how various chargers and USB cables fare on the same device.

If your phone is not connected to a charger, you see the discharging current which is negative. If you connect a charger then the current that the charger gives will be used to supply your phone and the remaining power will be charged into the battery. The app is free to use, although a paid version of it also exists. The ‘Pro’ version of Ampere gives you access to additional features including Widgets, notifications, alerts on device, and alerts on Android Wear. ## How to use Ampere 1. Open the Ampere app on your smartphone and let it run. It will start measuring automatically. 2. After a few seconds, the results will be displayed on your screen. 3. The app will show information about the device’s battery including charge level, health, status, technology, maximum capacity, temperature, voltage, and more. 4. Unfortunately, the Ampere app shows results in mA (milliampere). You can convert it into Watts, and check against your charging brick to see if you’re getting an optimal performance out of your smartphone’s battery. Considering that smartphones have become the single-most important device in almost everyone's life for professional and private purposes, the need to have it on all the time is critical. No one can afford to have it die on them for even a brief time. To ensure that does not happen, the requirement for an app like Ampere is high. And, what is more, it comes absolutely free, even though you can very well get a paid version too and that will have even more standout options to offer that you may well find very useful.
