I have now used Incredible S for a few days. I will say that the battery seems to last a working day for me, though not with heavy use so far. Data access is constantly on for me. I was trying to understand its battery draining characteristics by looking at the information about Battery use in Settings. I see that Display consumes about 70% and Locations 20% and then everything else. My phone settings are - display brightness is automatic, screen timeout 1 minute, Locations off for both phone network and GPS, Mobile data network ON, Background data ON, Auto sync ON (I have couple of Gmail account, 1 facebook, 1 Hotmail), Wifi coverage is available for almost 50% of the day. Most battery saving tips ask you to leave Android to manage screen brightness level automatically. Probably it is with some reason - in order to adjust to ambient light automatically. But then why is Display consuming 70%? I used to think that SLCD will consume less power (relatively, of course) but was surprized to see display as major power consumer still. I also note that at Automatic brightness control, the brightness level is quite bright, bringing out the beautiful SLCD display. I can definitely do with less brightness, but to manually adjust it will lose the ambient light sensing feature. Is there a way to reduce the brightness even with Automatic control?
