Why does my samsung galaxy A3 (2015) run out of battery so quick?

[AC Question]

I took my phone of charge at 7:00am today and by 10:00am my phone is on 54%. I haven't been on it as I am working so not sure what is wrong has this happened to anyone else.

Did you check your battery usage stats in Settings, Battery, to discover the cause?

I have checked it and seems to be fine now. Thank you for a quick reply

Good, and welcome as a new member.
Unexpected battery drains do sometimes occur, for reasons that are not always obvious.
