yes, that's the reason I replaced my Samsung Ace 3. Randomly ran the battery flat in 18 hours. Most days lost only about 20% charge.
Replaced battery. 16 days later, it happened again.
Checked what apps running in the background. None It happened again.
Obviously it was doing something, as it was notably warm at these times - as opposed to body temp at others (I keep my phone in shirt pocket)
no point in keeping it if unreliable - so it's been replaced. Not cheap, either.
Grrrrrr.
