Z5 battery lasts only 20 hours? It shows under settings and battery life

[vanille]

Yesterday, my battery status went from 55 hours left stamina to 20 hours in this morning and I didn't use phone in the night when I was sleeping. Any help with that? I reseted and still showed under 20 hours of life remaining battery. I don't know what else to do.

Go to .....settings - battery - then press the battery usage this will show you a graph & what has used most of your battery

I already did, and I didn't use phone for like 8 hours and it's still shows only 18 hours left of battery life.

Currently my phone shows 54% & 18hrs 30 min left.......it was left untouched for approx 8 hours from approx 78% battery left

I've had at like 75 % at the morning and it said it only 20 hours is left, before that morning the battery showed me that it will last 64 or 60 hours at 100%, and at 80% battery about 55 hours.

To be perfectly honest i wouldnt pay much attention to those estimates.....if you get anywhere from 30hrs to say 38hrs on medium to light use that is perfectly normal......tho it all depends on how you use the phone

Yeah I know, but it's totally unusual because it newer showed me before sucha low duration time, at the night I've had like 69 % and in the morning only 68%, just dropped 1 procent and still was showed sucha low duration time. And I didn't even use phone.

And now when I am charing it's at 92% and it only shows 25 hours left, which is almost 1 day, and it's very low. That didn't happened anytime before.

Unless you notice a substantial & sudden deterioration of battery life from your phone i wouldn't worry......if you did i would be looking at a possible 3rd party app being the cause

Well the battery yesterday started little more dropping, but of course of usage facebook, instagram and snapchat, at was getting a little hot, but I didn't dropped so much to be worried about, I also have a low signal in my room, and I think this could also be a little problem for battery to drop.
