After amber update my lumia 920 battery drains super fast but when i'm restarting the phone the battery level jumps to where it supposed to be.
Also when I chearg the phone the battrey shows charging but the battery percent keeps going down.
It happens to anyone else?

Make sure you are not signed in to facebook chat.
Do a soft reset (Different from a power off and power on)
Is your sim card old? (It can also kill battery)
Are you in areas with low/poor network connections?
Is 3G on all the time?
Are you running any weird apps (Like a monster named skype which eats nothing but battery for lunch/dinner)?

Make sure you are not signed in to facebook chat. I'm not
Do a soft reset (Different from a power off and power on) I did still the same
Is your sim card old? (It can also kill battery) I'ts the same even without a sim card
Are you in areas with low/poor network connections? Yes
Is 3G on all the time? Yes
Are you running any weird apps (Like a monster named skype which eats nothing but battery for lunch/dinner)? I do run Skype

The problem is less about the drain of the battery, because it isnt real whan i'm restart the phone the battery goes back to normal value, and also the fact that he w'ont show my charging.

The green points rectify your problem,
Try to turn off 3G and Skype for a day and see how it goes.

Look at the graph, it does'nt make any sense.

Update: After a hard reset, the problem is still exists.
