The information on the batteries of my tianhe h920 plus is contradictory and Id like to find out properly whether their size is 2800 or 1800 mah.
front label says 2800 mah, back label says 3.7v, 6.66wh which corresponds to 1800mah, not 2800.
How do I best test the battery size in practice questionmark
This can be a very tricky project. The only way I know of to test capacity is to discharge the battery with a steady draw and time it.
Less reliable, but still fairly accurate would be to discharge a battery completely and charge it with a known steady current and time it. But it's difficult to know exactly what current is being received. Your charger may say 500mA and that may be what it's putting out, but 500mA may not be what the battery is actually receiving /accepting. I've got a tickle in my brain about being able to monitor incoming mA through an engineering mode, but it's lost in the fog right now.
MTK Mobile Uncle shows me the current energy consumption of the phone. It has an option to make a log of battery use, but the logging does not record this energy consumption statistic...
Would have answered all my questions if it did.
Does anyone know of a battery log program that records Engineering Mode's Current_Consumption statistic as it fluctuates over time?
Can such an app be developed maybe? Or is it impossible to get that reading outside Engineering mode?
