How many hours does 4000mah battery last.

How many hours does 4000mah battery last. If 1000 mA 1 A is being drawn the same battery will last 4 hours. A 4000mAh battery on a smartphone will ensure the phone should last well over a day depending on how heavily you use it. Assuming this is a typical lithium cell phone battery it has a total power storage of 12950mWh.

The fact that we may have access to chargers throughout the day or own external battery packs isnt an excuse. But how do you calculate that in a 4000mAh phone. How big a battery should you use.

Similarly a 2000mAh battery will give you 2000mA 2A for one hour or 1000mA 1A for two hours. If you draw 2 mA for 5 hours you have used 2 mA 5 h 10 mAh. With a AA battery rated at 2000mAH it can power the circuit for 2000mAH200mA 10hours.
