My battery is draining too fast without using my phone

Hello. I use Alcatel one touch idol 2 and I haven't experienced problems with my battery before. My android is 4.2.2. Suddenly since 3-4 days my battery drains really fast without even touching the phone. I looked at different threads for solution, but nothing. I think I disabled every kind of tracking my location or things like this. I'm losing battery even in Power Save mode and in Flight mode, so nothing helps.
What I found interesting is that my phone is ALWAYS wake up, his time in "Deep sleep" is 0s. I think something is causing the phone to be awake even when I lock it and don't use it. I tried to remove different apps, but that also didn't help. I'll try to upload some screenshots from my phone to show you some data from my battery.

If you regularly drain the battery to close to 0%, it could already be dying - you should charge it when it gets no lower than 40%. (I've seen batteries a lot newer than 18 months old die from constant drain to 0% or close to it.)

No, I'm almost sure that's not the case. I usually charge it when it gets 30% or lower.


I think it is not normal my telephone to has 0s of deep sleep, is it?
