Just used OTA and updated to Verizon 4.0.4 ICS on my droid4. I have used the new system for about 48 hours. Well, the body is a little hot... alright, the actual issue is that last night I fully charged my phone and went to sleep. 6 hours later when I woke up there's only 30% battery left and Android OS has taken up 85% of the power usage.... Is this normal? Wifi off. Auto Sync/4G on. Not rooted yet, that is, the official rom state. Well someone suggest the ICS system will first indexing the files so the battery life will be terrible for the first day. I just wanna know for you guys how long do you wait until the battery life get normal? two days a little too long?
