im pleased you are happy with your phone, im not saying the samsung is a bad chip, just most of the evidence suggests the tsmc is better overall
personally I think it's far too early to jump that conclusion, the panic seems to have driven a couple of people insane, and really the evidence seems to show the geekbench battery test is an anomaly, so far we have:
the geekbench battery test which shows a massive difference between the two chips.
all of anandtech's benchmarks minus the geekbench battery test show the two to perform within a few percent of each other, the geekbench battery test of course shows the TSMC chip massively ahead.
tomshardware performed their own suite of benchmarks and also found the two chips within a few percent of each other.
several other sites have found the same with real world usage tests, there was a german one somewhere in one of the threads with a pretty good real world test between the two which in the end showed them to perform nearly identical and battery life was within two percent between the two, the TSMC finished at 38% and the Samsung was at 40%, a difference that could easily be down to manufacturing variance.
several video's running a variety of tasks in a real world setting show the performance to be very close, I've included the most thorough in this post that runs several CPU intensive tasks for a long amount of time, the end result is they are within 1 percent of each other in regards to battery and a minor difference in length taken to perform the tasks, again perfectly normal variations in the silicon lottery. they also run the geekbench battery test and it as usual it shows a massive difference between the two, it's possibly the best evidence I've seen that the geekbench battery test is not just an anomaly but it seems to be flawed, however I have no idea what might be causing it, hoping it's figured out soon.
apologies for the long post, honestly I'm just waiting to see what's going on. I would rather wait until we know the answers before forming a conclusion, anyway, haha it feels like I've recounted the last couple of days just about in regards to chip gate, the video I mentioned is below.
