I've really started to notice my battery is not lasting the full day. Its mostly just on my desk all day but come the evening, the battery is saying it needs charged. 

Im not sure how to work out what might be draining it or what I might be able to do to investigate or fix it - so any advice or suggestions would be most welcome!

Hello... look at your 'in deep sleep' time and 'screen off' time in accubattery compared to mine... this could be why it's draining as it not really 'asleep' when the screen is off.

CHECK YOUR BATTERY SETTINGS from Device care. Set each app to use background battery or not. I use AOD all the time lasts easily 24 hours with on screen time of 3-4 hours

That wont matter so so much, it does but it is not the killer. He has some apps that are killing it, maybe too many notifications from several apps but background battery use of those apps.

thank you. I thought that, but I'm not sure what's keeping it on. there were some apps not in optimising, and I've put everything to sleep that I don't need the notifications for, but it's still saying it estimates the phone lasting 14hrs... any other suggestions welcome please!!
