Lots of iPhone users are complaining that the battery life has seriously dropped since the release of iOS 4.3. On the Apple discussions Forum there are a several number of complaints regarding the shortened battery life, but complaining isn’t the only thing they are doing cause they may found a workaround.

Several users report that the built-in Ping function could be appear to be the cause of the shortened battery life. Ping uses its own framework and this seems to ask a lot of the processor and network traffic. This may be caused by a bug in the framework which causes ghost processes.
We can however disable the Ping feature under Parental control. You can do this by browsing to settings > general restrictions and turn off the Ping option. After that it is better to restart your iPhone, to close all ping processes.
You should notice a improvement in battery life, and it is possible that Apple will fix this with a quick iOS update. Until then we suggest you keep ping turned off.
