Power Capacity and Power Capability | All About Batteries
The way the power capability is measured is in C''s.A C is the Amp-hour capacity divided by 1 hour. So the C of a 2Ah battery is 2A.The amount of current a battery ''likes'' to have drawn from it is measured in C.The higher the C the more current you can draw from the battery without exhausting it prematurely. Lead acid batteries can have …
Is there a way to automatically turn on battery saver?
If you go into Device Care, go to the 3-dot menu and select Automation, you should be able to turn on Adaptive Battery Saving. If you do that, your phone will automatically turn on Battery Saver if it reckons your phone will run out of charge before you charge it again. It''s pretty smart. You can also tell it not to turn off 5G and stuff.
