Galaxy S 2 (II): Battery Life - Heavy Useage with Wifi

In my previous post on battery life in the Galaxyy S 2 I wrote about how the device copes under what I would call "moderate usage". Here I will briefly summarise a charge of the phone under typical(?) "heavy usage". 

For me, this involved:

• WiFi on constantly
• Multiple games and keeping those games running in the background
• Various other applications (a total of 25 apps/games by the end of the charge)
• 30 minutes of high definition video content
• 3G/HSDPA on constantly with hour in total call time
• Screen on 100% brightness
• Lots of web browsing
• Sending emails
• Updating facebook status
• Checking Reddit.com (fellow reddit users will know this is almost a constant thing...)
• 45 minutes of GPS usage
• Not clearing the RAM
• Skype, Gmail, Facebook, Twitter all updating
• Microbes Live wallpaper
• Widgets for weather, stock market + gmail
• A series of alarms set to go off throughout the day

For those interested in "standby time" with and without WiFi, I decided to have a period of no-wifi standby and then "with-WiFi" standby at either end of the period of heavy usage

You can split the usage here into thirds: 

1. On standby - only 3G/HSDPA on and background socialnetwork/email sync. WiFi Off (12 Hours)
2. Phone on about 50% of the time, Heavy Usage, WiFi On (12 Hours)
3. On standby, WiFi On (12 Hours).

 With that in mind I would expect to get a good 14-15 hours if I had started with heavy usage from the start. I would imagine that most people need to sleep and have a break from their phone at *some* point during the day (to sleep, for example?) so it looks like the Battery life of the Galaxy S 2, even under heavy usage will be more than sufficient! Hurray!
