I want to know if AirDrop and AirPlay can work on an iPhone 4S

I want to know if AirDrop and AirPlay can work on an iPhone 4S

I have had the same issue with VERY rapid battery drain, measured to the point of losing 2-3% post-calibration charge every 5 minutes at idle (no apps running, and screen off), plus the extreme heat generated. I was even losing about 1% charge every 15 mins while plugged into an Apple iPad USB charger.
I have been one-by-one disabling groups of services, and enabling parts of them in order to correct this. I have after days of trial and error found that (at least in my case), that nothing really made a significant difference until I turned off contact sync for iCloud, with all other iCloud services are on using the defaults.
I have left on Siri, all push (email and otherwise), notification, and location services, WiFi, bluetooth, and have brightness set to a comfortable 50% with auto-brightness on. (FYI: My other 5 emails are all set up as Active Sync)
In working through this process of elimination, I have now reduced my battery consumption to less than 1% battery charge loss every 30 minutes, and hope that it may help you as well.
Now I understand that everyone's setup and experience will be different, but this has been 3 days of initially freaking out and then finally getting down to methodical testing in order to avoid possibly having to return a faulty phone with extreme overheating and battery problems. I'm not sure what the issue may be, but hope that it's just a bug, but until it's all fixed, I can live without iCloud contact sync.
