    Short version:It's back! This time with all the right footage:)
    Long version: I uploaded this video yesterday, but had to remove it and reupload it today, because it was missing a bunch of footage of everything I was doing on my workbench. It's a long story, but I made a mistake when I rendered out the final video, which I didn't catch until some of you guys with sharp eyes noticed I was looking up at an overhead camera but that you weren't seeing any footage from it, and mentioned it in the comments. So thank you for the heads up! It's fixed now, and I watched through the whole thing to make sure this version is what we intended you to see. Thanks for your patience, and sorry if you were in the middle of watching when I took it down yesterday, or got a notification and then couldn't watch it. I just really wanted to make sure you could see the full version we worked so hard on.

      ...Why? Vlogging/video recording in public is less normalised in China compared to the US. Plus, tech markets in Shenzhen usually ban video recording. The dude here may not have arrived at a market yet, but him recording while walking still looks weird to people.

    New batteries are actually never fully charged for transport regulations due to heat buildup and self-combustion when allot of these are packed together. It's kind of a huge bomb. Batteries fully charged are the ones you must distrust. You noticed that you can reset them. The less charged they are the better it might be. Also test batteries when fully charged only or you are comparing chickens with cows so basically for science you can start this video all over again LOL.
    In terms of original batteries or not it doesn't matter much. It depends on what Lithium factory has the better price for the hardware manufacturer and they slap on their own controller. The capacity is the number it is shipped with and is often very correct or they would be out of business pretty soon right. Customers will come back when you lied to them as a manufacturer. You basically pay more for the battery controller that is original or not and it's nothing more than an interface with diagnostics. In terms of how long a battery will last depends on something similar like the silicon lottery. The fact a battery is original says zip. a cheaper non-original can be better in terms of lifetime when the lithium is of better quality.
    I noticed that original batteries are actually very overpriced towards actual quality, because the phone manufacturer wants profit over hardware. The battery manufacturer doesn't have this problem. Batteries that come with the device are often worse than after market batteries. You might find out yourself that any changed battery might last much longer between charges as well as overall lifetime.

    As a tip with buying batteries in Shengzen: You can see the real battery capacity after first full discharge after use. (let it die) You can know the batteries real-rough life cycle after about 2 weeks of use. For me, a battery bought on the streets lasted me about 2-3 months before it died. They can use that machine and machines like it to program the meta data to think it's "original" or "new" but in actuality it's second hand or less capacity-off brand.

    for the amount of time you used that "tester", it was completely useless. you cant tell the quality of a battery immediately like that. it requires at LEAST one full charge and discharge cycle. also i HIGHLY doubt any of the apple branded batteries in china are BOTH new and original. there are tons of fakes. that lady that scrubbed the logo off even had the tools at hand to scrub logos off things because thats what they do in china.. copyright infringement.

    Einstein mode ON
    to be able to really check the capacity, you gotta do a full charging and discharging cycle on the battery. you have to discharge it at a constant current, which lets say is 250mA to keep it close to what a phone would use, and see the total amount of current drawn from the battery when it is down to it is minimum voltage level, i.e. when it is empty. That machine just probably does some inaccurate calculations to tell you capacity, that is all. Because due to the fact that the characteristics of a battery is not the same at the percentage of 100 or 50 or 20 whatever, it cannot just calculate the discharge rate for 10 minutes and multiply the amount drawn with six and tell you the real capacity, this is just inaccurate.

    Are you 100% positive that the battery that has a larger capacity actually has a larger capacity, and that there is not a chip installed that makes it seem so. I don't believe there is a way to make a lithium Ion battery with a larger capacity unless the battery itself is larger. There is a large history of fakes over the years and that has always been the case. Does it actually last longer then an original battery?

    Nice Video. You convinced me, running around in China and spending 200 Dollars on several batteries, tools, materials and a tester to find out which one to use is better than paying 49 Dollars to get one from Apple with Warranty and functioning Waterproofing. I am sure the battery booth ladies, all if which have these "testers" don't use them to reset cycles on the batteries they sell. I really like the Shenzhen Idea but this whole Vender-Booth system seems super shifty. As for the "It's up to the consumer to figure out what to put into the phone" ... I would not trust the average iPhone user to figure out what to have for breakfast. And Apple People replacing their own battery? Hahahahahahaha .... oh that wasn't a joke.
