Hi.
I was wondering if the frequency used by a given carrier or even the carrier itself can have an impact in power consumption. I ask because I changed carriers a few months ago and I noticed a considerable decrease in battery life soon after.
Whenever I'm on mobile data, the device can draw up to 8%/h (I'm using Battery Monitor Widget for this) from the battery when idle for several minutes, until it eventually drops to 1%/h or less if left completely untouched during that time. If I use the phone, even briefly, and put it down, it'll start and stay using 3-8%/h again when idle. This doesn't happen at all when I'm on WiFi.
My old carrier used the 1900 Mhz frequency band for 3G (850 for GSM) and the new carrier uses the 900 Mhz band for both 2G and 3G. If I keep my phone in 2G only , the drain is not so bad (could be maybe 1 or 2%/h, still rather high, but not something I'd worry about), but on 3G it goes crazy. I know that signal strength can have an impact in power consumption because the radio is constantly scanning or trying to connect to a poor signal, but this happens everywhere, good or bad reception.
