This doesn't look normal to me.. I tried resetting SMC and reinstalling MacOS. None helped increase it. Is this normal? I'm worried..
I forgot to mention in my post that I tried that a couple of times, unfortunately to no dice.You can try to calibrate the battery measurement. I haven't done this in awhile, but I think you use the MBP until it shuts off due to low battery. (Ignore the low battery warnings, but make sure you've saved any data before it shuts off.) Then let it sit for a few hours. Then charge it fully. See if that changes the capacity measurement. You shouldn't do this too much since it's hard on a lithium battery.
I'd live with it then. See if it adjusts itself over time. I agree with you that it shouldn't be showing that much wear at this point, but battery capacity measurement is always an approximation.I forgot to mention in my post that I tried that a couple of times, unfortunately to no dice.
Are you always on battery? 90% of the time I work on the computer besides being on the couch I'm plugged in.
Correct, every laptop has a differently sized battery. My 2017 MBP 13' has a 4315 mAh battery.You're comparing your 15 inch MBP to his 16 inch MBP. Different machines.
I was just charging when I took the photo, I've only had the laptop on for about 2 hours since I bought it.Are you always on battery? 90% of the time I work on the computer besides being on the couch I'm plugged in.
Also I rarely use the dGPU only when connected to displays
I calibrated it multiple times... I’ll keep an eye out on it. Thanks..Yeah this is definitely odd. My mid 2019 15 inch (bought on launch) was 102% out of the box (?) and is at 98% now. It abruptly dropped from 102 to 98 over the course of a couple days like a month after I got it and it hasn't lost any capacity since. I would definitely worried/confused if I was in your situation.
Apple isn't going to do anything unless it drops below 80% capacity before your 1-year warranty or AppleCare expires. If it does, they will replace the battery for free. So... I guess you're fine. I would just keep an eye on it.
Maybe your MBP was exposed to a lot of heat in transit or something. Or maybe the capacity it's reporting isn't even correct. I would calibrate the battery if I were you.
How is coconut battery more accurate than apple’s internal testing tools? I took it to an apple service provider a couple of weeks ago, since we don’t have apple stores where I live, they ran a diagnostic test and it showed the battery as 97% at the time coconut battery was showing 95-96% and told me it was normal :/ and that I shouldn’t be worrying, but you know even you think it isn’t normal so.... I don’t think I can get it replaced here at all. Anyway thanks for the detailed response :/.There is a lot of misinformation in this thread.
Since I’ve got multiple paid/free replacements across several continents and several category of Apple products, I consider myself an expert on this subject.
1. Apple doesn’t use Coconut Battery. Their internal diagnostic result has near 0 correlation with Coconut battery. However, Coconut battery is way more accurate than any tool Apple will ever use. What I’ve seen is as battery health degrades below 100%, it actually shows a far higher figure than the real health. That’s why you only get 5 hrs with 93% health. Whereas a truly healthy brand new battery might have given you 7-8 hrs.
2. If their internal tool says you’ve lost 7% in 32 cycles, there is a 80%+ chance they will replace your battery and/or device as long as it’s still under warranty. Such a situation falls under exceptional circumstances, and if you get the right genius at Apple, they will oblige. You might need to try more than once though.
3. Keeping 2 in mind, this is 100% a reason to be worried and this is far from normal. I won’t get into the specifics, but in most cases Apple devices last the longest time on the percentage they were out of the box. If not, they stabilise quick. Even though real world usage will keep decreasing. But that’s another point. Anyway, you should be worried. And if you contact Apple enough times and properly, they are very likely to change your battery or device.
4. Do buy AC+ but if you can. There is a very high chance it will fall below 80% within 3 years. But it definitely won’t within 12 months. This is your last resort.
5. Even if Apple does give you a new 100% health battery, you’ll be back to 5 hour battery life in 3-6 months tops. This is how fast MB/iPad batteries degrade. iPhone batteries are built to a far higher spec no matter what you’ve read or been fed by everybody around you.
