Download GSam battery monitor from the Play Store to determine what is causing the battery drain.

The battery drain during usage is within the normal, but in standby it is too high, which I do not understand!

Using the battery app see what app or service is keeping your phone awake. That would be my guess as to what the problem is. I would also suggest flashing cpalmers kernel as well, which has been really good for me in limiting awake time.

Install BatteryGuru, give it a couple days to learn how you use your phone, and watch how it saves your battery once the learning period is done. I swear by this app, it brought me from almost a day to about a day and a half as far as battery life is concerned.

I installed the Gsam battery, it shows that "phone radio" was sucking down a vast majority of the battery.

Then you must be in an area where service isn't good and your phone is searching for service which kills the battery quickly. To conserve battery turn on air plan mode and then turn service on when you get into a zone with better coverage. This will help your battery a lot.

My opinion..don't install any more apps than what you only use. You install more apps it will obviously suck more battery. What you do. Root/unlocked the bootloader and install a sense 5 4.1.2 base Rom. I came from stock and since I've installed a sense 5 stock Rom I've notice a big battery saver comparing from the original sense 4+ stock.hopefully that helps.

Thanks all
Strangely none of this helped the battery drain is too high in standby, after resting (no apps installed only stoke apps) and even flashing sense 5 rom still 15% per hour and even in Air plan mode . The strange thing during the use of the phone the drain is normal.
