Most stock chargers should charge your device’s battery at about 1000mA. If you think that your device’s battery could be charging slowly, try this app out “Galaxy charging current”. I noticed that my phome was charging slower than it should, so I tried this app and I found out that it was charging only with 100 Mah. I tried everything and a factory reset did fix the problem.
Check the current_max value If it displays a value much lower that 1000, the battery is charging at a lower current than desired.
The application is confirmed to work correctly on the
