My battery is draining much faster than it was before. Samsung Galaxy A5

[AC Question]

Since a week or so my battery is draining much faster(at the end of the day 30-40% should be remaining but now it is empty at the end of the day). Also, I think this might be the cause, often when i unlock my phone it says "Bluetooth was stopped(not sure what it is in English)". On top of that my phone is not connencted to W-Lan when locked so when i unlock it, it connects with the W-Lan even though it should alredy be connected.

Are you using a bluetooth device on your phone or do you just leave it on?

Also, you're probably allowing W-Lan to sleep when the phone does, That turns W-Lan (Wifi) off when the screen goes to sleep, so it should save some battery, but you'll miss notifications that only come in via wifi.
