Sorry I don't have time to spend on battery debugging. This is something apple employees should have done since they're the ones that receive salary, not me. I am actually debating whether to keep it OR return and re-buy in September before the student discount expires. If I keep it my plan is to use it for as long as possible and before the 1 yr warranty lapses go and get a new battery. What I am afraid of though, that they will somehow fix this hardware issue with a software patch and refuse the new battery, thus I will be stuck with a lemon battery forever.
I agree, it is not our job to do but what you gonna do, these are what they are. Then again how much time you have already spent getting machines replaced one after another?Sorry I don't have time to spend on battery debugging.

Define all the folks? Have you seen more than one CTO owner testing their machines with ways described in this thread?Most (all?) of the problem batteries appear to have been from machines with the standard 1.4/8/128 or 1.4/8/256 configurations. All the folks with CTO builds appear to be having no issues.

I'm not sure how many peoples even ever test how low they can take the battery let alone measure how much actual battery percentage they can get until charge cycles increases. Not complaining is no guarantee there is none.
Yeah, but only two don't make all. Could be just that folks ordering CTO machines don't much waste time on testing this.Only talking about the case where machine shuts down when the battery is at some % that is >> 0%. It seems like there have been several complaints from folks with standard configs but none from folks with CTO configs. I have seen 2 so far about CTO config being fine and none saying they exhibit this problem.
I'd say these things are all more or less related, peoples are just more or less concentrating issues they find important to them.As to the cinebench testing, I'm not following that one as closely. I agree with your sentiment on getting more test data. But it looks like the problem affects both DSY and Simplo batteries?
I know one guy from different forum who ordered 16/128, did two "full to empty" cycles and had zero issues.Most (all?) of the problem batteries appear to have been from machines with the standard 1.4/8/128 or 1.4/8/256 configurations. All the folks with CTO builds appear to be having no issues.

Well, I used word could. Anyway, using the same analogy, I say you cannot either make statement like you just made.I appreciate your sentiment and trying to trace the problem, but you cant make statements like this.
On the flip side, you could argue that maybe 5 people have issues with shutdowns but that doesn't mean all.
Not all CTO buyers are enthusiast closely following a forum for the base model MacBook Pro to report results to your tests.
It could also be that the ones who you claim have not done the test, have no issues and no need to come on here to report that they have no issues.
Can you enlight me what you think is the reason CTO units do not suffer from this? They are better parts for some reason or what? If you think they are build from the better parts, then why they cost the same as stock units with the same configuration?@ghanwani statement makes sense. The ones with CTO like me don't have this issue so from the sample that tis available it seems to be the stock models with this issue.

New 2019 MBP 13", 1,4ghz, 16 Ram, 256 SSD.
Received with 100% battery, drained to 4% then connected charger. Now 100% again and Cycle count = 3????
Got more than 10h usage, only browsing Safari though.
Do you see any issues here?
There usually should not be more than 1 charge cycle when it is new. Actually most Apple gear I've had came with 0 cycles out of the box. My MBP came with 1 cycle on the counter out of the box. The only time I've seen 2 cycles on the counter was when I bought iPhone X (brand new sealed retail unit for official dealer) at the end of last year. It obviously had interesting history as manufacturing date based on the serial was earlier than what the date marking on the box said. So obviously it had been charged again at the factory for some reason. BTW. that unit has had always very weak battery.
But since poster said he ran battery from 100% to 4% machine may be counting cycles faster than actual 100% use. Mine seem to have accumulated 1 cycle increase in about every 50% to 90%, speed seems increasing all the time.
Also it is usually uncommon to receive machine with battery 100% charged. Usually Apple gear seem to come with about 80% charged battery.
So, I'd say keep the close eye on the battery performance if you also see any peculiar things with it, like noticeable FCC fluctuation under high cpu load or similar. That seems to be also rare issue only few are suffering from.
I made that mistake I kept ignoring all these red flags with mine as there was not much comments about battery back when I got mine (tried to convince myself they are normal for this model) and now it is too late to return and since battery is over 80% capacity it is not considered faulty... Battery life has taken a big downfall in past few days in my unit, it was much better than now just few days ago.
Anyway you mentioned your ran over 10 hours on first charge is actually very good. For example mine has just fall 100% to 37% in just about 4,5 hours running Safari. It used to be more.
This is so annoying and sad. Why don't you go to Apple and report the issue?Definitely something has changed in my unit after the latest Mojave update last week. Not sure it that was the reason or not, as the change I'm noticing did not happen immediately but next days after charging the machine again.
Anyway, the good things are so far that battery meter seems to act more reasonable so that charge level from 100% (in Coconut, or course as it shows the actual real charge level) drop almost immediately (it was before update in situation where I could run it for 1,5-2 hours until it dropped under 100% the first time). Also full charge capacity does not seem to drop under high load like Cinebench test but stays pretty steadily where is was before running the test. Also charge cycle counting seems more reasonable in percentages as I got just little over 92% of use until it increased the last time.
Then the bad things. Battery life in generally is now very poor, I just got under 5 hours until battery went from 100% to about 36%!!!. Also while charge cycle counting seems more reasonable in percentages, when I compare actual running time on battery to the time where I had it increasing crazy fast (like around 60% or so), the actual time in hours is much less now (just below 7 hours per 1 charge cycle increase now). Also under high load test (Cinebench) the total charge level drop is somewhat higher than before when FCC used to do huge dips.
As to sum up. Is seems as if it does not allow to use full capacity of the battery any more, or battery just has lost its capacity in just 24 charge cycles (which is possible too these days). Is it simply possible that they adjusted something so that you cannot run battery as low as before to "fix" issues where some peoples saw their machine suddenly turning off when battery meter was still showing around 20 to 45% charge left?? Mine never seemed to have that problem with turning off but I could see battery voltage getting very low at low charge percentages and that FCC fluctuation got crazy high at the lower charge levels. I also never done SMC reset in my unit. Definitely looks like it does not allow to run battery as low as before...
It would be nice to hear if anyone else has been keeping an eye on their units and saw any charge happening recently? Probably again something nobody else is seeing with their machines...
