During the night my battery drains 60% (!!) with airplane mode and all the apps shutted down.

So, this phone is a Jiayu S3 advanced model and I got it 2 days ago.
I turned off all the sync, no widgets on the screen, just a simple clock.
I've checked it with CPU spy, and it goes to deep sleep, still I loose 10% of the battery in EVERY HOUR while I don't touch the phone. In battery usage the main consumer is "battery-idle".

I don't know what should I do with it...
(I had chinese phones in the past and never had a problem with them)

Two days is within replacement warranty, so ask them to please replace the phone with one that works.

Hi Rukbat,

Thank you for your answer, I've already contacted the seller. He said I have to make a Factory Reset. Even though it was strange to make it on a new phone, after that everything worked normal, now the battery drain is less than 1% per hour.
