i brought 2 phones to the new year party last night: a samsung galaxy s3 and an iphone 6. both were fully charged by 4pm. wi-fi on both were shut off. both are on the same 3g and 4g lte network. i carried the samsung in my left pocket while the iphone went into my right pocket. drove 1 hour to the venue, and the samsung was already 98% while the iphone was still at 100%. network coverage on the freeway was good. went indoors, after 15 minutes, samsung was down to 96% while iphone was at 99%. as the dinner crowd showed up, network started to get more congested. bars went down from 4 outside to 2 inside. during dinner from 6pm to 8pm, samsung went down to 90% while iphone stayed strong at 96%. d.
