DON'T LET THAT CHARGER FRY YOUR PHONE!!
Know what? That charger you use to charge your device might be killing its battery slowly and steadily. Overcharging side-effects are often hidden and are occasionally seen in the form of devices getting unreasonably hot while charging.
While humungous power consumption from a battery does little to affect its life, the rate at which it is being charged can leave a considerable impact. A powerful charger can charge your device fast, but it might reduce your device's battery-life. CHARGING CURRENT IS AN IMPORTANT METRIC HERE.
MOST BATTERY UPDATES ARE IN THE FORM OF A PERCENTAGE OR VOLTAGE THAT DO NOT REFLECT THE CHARGING CURRENT OR EFFECTIVE CHARGING CURRENT.
Enter Battery Meter...
Battery Meter provides you three important results:
1. The EFFECTIVE CURRENT which is being supplied to the device when it is charging.
2. The TIME it will take to charge the device given usage doesn't change.
3. A HEALTH INDEX telling you how healthy this charging current is for your device's battery.
Using battery meter is very easy:
1. Launch the app and select your device.
2. Once your device is selected you will be redirected to the results screen. Plug in your charger, tap to begin measurements and let battery meter do its job. DO NOT LOCK THE SCREEN.
3. BATTERYMETER WILL TAKE SOME TIME TO COMPLETE ITS ANALYSIS. After its analysis is complete, you will be presented with the results.
4. Tap on the results to know more about what they mean.

IMPORTANT NOTES:
**BATTERYMETER WILL TAKE A WHILE TO FIND OUT THE CHARGING CURRENT ACCURATELY. DEPENDING ON THE CHARGING CURRENT VALUE, IT MIGHT TAKE MANY MINUTES. PLEASE LEAVE THE APP RUNNING.
** MAKE SURE YOUR DEVICE IS PLUGGED IN BEFORE YOU BEGIN MEASUREMENT.
Whats new in version 1.4
** Galaxy S4 is now supported
Whats new in version 1.3
****** Added a refresh button that allows the user to refresh measurement.
****** Improved current estimation algorithm.

Nice idea but there needs to be an option to pick an off brand tablet/phone. Like "No brand" or "I don't know." Then manually input the battery type and voltage.

Right from the start, the description lies about the nature of lithium batteries - they CANNOT be "overcharged". Ever. Unless the device is malfunctioning or the battery is damaged, lithium batteries by their design cannot be overcharged no matter what "charger" (power supply) you use with it nor what software you use, how long you have it plugged in, or anything. Lithium batteries *must* be voltage-regulated in order to operate. Charge tapers off and stops at 4.2V as "100%", and ends at around 3.2V for 0% (some use 3.0V to compensate for voltage drop while under load). This is common to all devices that use lithium batteries - if you go over 4.3V, you physically damage the battery. The charge is controlled by the phone hundreds of times a second, and won't go over that voltage unless it's malfunctioning. Overcharging isn't an issue - but keeping it at 100%, leaving it fully discharged, or exposing it to high heat (120F+) will damage it. Lithium likes to stay 30-70% charged. This is common knowledge easily researched online. The app does nothing - it just says "device unplugged". I just want a simple app to read /sys/class/power_supply/battery/current_now in near-realtime.

I can't say whether the app shows accurate charging current, since I haven't found another app yet that works on the Verizon variant of the S3. But there are so many other issues that it's not worth using even if it is accurate: - took 30 minutes to perform its analysis while charging from the USB port of a computer! (Did this twice just to cross check. Current shown was 243 mA, which seemed low.) - took multiple Back button presses to exit the app - web page is formatted horribly; essentially unreadable

I'd appreciate more documentation - the app is pretty bare-bones. Also it has taken up to 20 minutes or longer to complete the analysis. I have a Samsung Galaxy S4. If I want to check another charging device it seems that I must close the app, unplug the cable, re-launch the app and re-apply the cable. Is that correct? I could not find any documentation to tell me anything else about the operation or the developer.
