I have a blackberry 9900, my battery last about 4 hours.  I have Facebook. whatsapp, twitter and wechat.  After doing the following steps it was clear that twitter was using the CPU a lot more then the other applications, I went to twitter application in settings my phone was refreshing feeds every 5 minutes. I set it to 1 hour and now my battery lasts up to 40% longer.
