The battery life is one of the most crucial aspects of any smartphone. 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!

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.
The Ampere app lets users check the charging and discharging current of the smartphone. 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,
