how does an mAh work? How long will 1 mAh last on a smartphone? How long will 18000 last?
In: Technology
Completely depends on how much power the phone is using. A 1800 mAh battery can provide, on paper, 1.8 amps of power for 1 hour before being completely drained. Or it could provide 0.9 amps of power for 2 hours. How much power your phone uses can vary hugely. If it’s in airplane mode with the wifi and screen off you phone will use almost no power and a 1800 battery could probably last 2-3 days. On the other hand if you are playing a cpu/gpu intensive game while heavily using wifi you could probably blow through that in 2-3 hours.
