Galaxy Note 2 Battery Drain Issue

[Alberto Note 2]

I have a problem with my Galaxy Note 2. It's have been a couple of days that I turned off my Cell phone, charged it and the next day when I turned on my cell phone, the battery level is at 50+%. I tried the following: changed the battery, factory reset, took out memory card but the problem persist. Other than this issue the cell phone works fine. Anybody knows a solution for this issue?

Thanks!

Do you have any battery apps to determine if there is an app causing the drain?

I use GSam and Wake Lock Detector, it helps to know what is draining the battery. Let us know if you find anything. Also post screen shots, that helps with the diagnosis too.

I am facing the Battery Drain problem in my Galaxy Note 2. I charge my phone in the night and its show 100% and when I grab it in the morning it shows 50% or lesser, I have downloaded number battery saving apps, keep mobile in power saving mode, backgroud light in zero but still facing the same problem and I found this problem after upgrading the phone in 4.3 Jelly bean.

Anybody knows a solution for this issue?

Thanks!
