Hello!
 
My Lumia 800 has been a rapid discharge of the battery. When viewing the Battery Status of Nokia Diagnostics at this point the current consumption is about 250 mA. However, no background tasks has been started; Wi-Fi, BT, 3G has also been disabled. Cure the switching off and on the smartphone. In normal mode, the current consumption is about 70 mA.
 
So, there are the questions: Can it be because of busy tasks that do not appear in the list of background tasks? Maybe some application not properly completed and continues to "load" my smartphone? How can I track this applications? What can i do in this case (except for the on / off the smartphone)?
 
P.S. Lumia 800 I really like, but such situations are highly upset.

What battery life are you getting from your phone? As long as battery life is reasonable, you should not be too worried about occassional high readings when you check the diagnostic because you could have just woken the phone after a period of unuse.

The average battery life of my smartphone is about 3 days. The incident happened after I forgot to turn off the charger at night. Morning disconnected from charging and the battery is discharged to 40% on the day. In this case, the current consumption was 250 mA. As soon as I switch off / on the smartphone, I have restored the previous consumption of ~ 70 mA.

P.S. Before that, my child ran a few games and left them in the background. Before charging, I closed them. Maybe some of the games was remained hanging in the memory?

3 days? That great for any smartphone. I get between 2-3 days myself. Like I said earlier, I would not be too worried about the occassional power spike as long as the overall power consumption is fine. Probably the phone preforming some systen routines in the background or perhaps synching emails and is normal.

Such a great battery life is because 95% of the time I spend only for a few calls, SMS and calendar. Wi-Fi switched on for 5 minutes per day to synchronize e-mail and calendar events with computer.

The strange thing is that consumption does not fall within 5 hours (until my intervention).
