I've read mixed reports online about which radio uses more power -- 3G or 4G. Has anyone done any semi-scientific tests that would answer this question?
- When constantly downloading data over the same period of time, which uses more battery (battery drain per second of download)?
- When downloading the same amount of data, which uses more battery (battery drain per KB)?
- Do both radios sleep with the same consistency? Do they use the same amount of power when sleeping or is one better than the other?
I don't think this is a simple question since the different frequencies might take different amounts of power to transmit/receive, since 4G is faster and may get to go back to sleep sooner, since the process of holding onto a signal may be different, etc.
My city won't have 4G until the end of the year but I'd really like to know.
