The standby time in ultra power saving mode on Galaxy Alpha shows a sudden reduction after a short call although standby time on screen did show possible standby time of a few days. What is the problem?
The maximum standby time shows the approximated amount of time remaining
while the device is not in use before the battery power runs out.
If you use the device for call or internet purposes then energy from the battery will
be consumed, and so the standby time will shorten.
