A couple of days ago I took some advice from this forum and switched off mobile networks. I sit by a computer all day with no need for email or internet for the most part. I have leak V2.1.2b. I use Touchdown for 4 email accounts although it will only sync one at a time and Gmail sync when on mobile. My battery life without mobile was about 90% last night whereas usually it would be at 30% or lower. I used the phone a lot yesterday, got some text messages, pretty much the same as the previous days. So what is going on? Why does the mobile network drain the battery so much? On my BB Pearl I had a mobile network on all the time, syncing 4 accounts every 15 minutes and never such drain as this. BTW, it was way worse drain on 1.5. It just sounds weird, like the radio is inefficient or something. Any and all thought welcome.
