1 New Replacement Battery Capacity At 54%
The Google Pixel battery is supposed to have a capacity of 2770 mAh. When I installed the first replacement battery (from Amazon), I went through the calibration steps (let the phone go down to 4%, turn it off, and charge to 100% two different times. Then I waited a week allowing the AccuBattery to do its thing, which eventually showed the battery health at somewhere around 1200 mAh.
I then ordered another replacement battery through iFixit (it had the same HTC sticker on it as the battery from Amazon), went through the same calibration steps, and ended up with a health of around 1400 mAh according to AccuBattery. I can live with this because I’m not going to tear this phone apart again but I’m just wondering if this diminished capacity is typical of replacement batteries. Is it because the replacement batteries were made three years ago when the phone came out and the batteries have just been sitting on a shelf somewhere with their capacity slowly diminishing over time?

I have the same problem with my Pixel XL. According to AccuBattery, the replacement battery is no better than the original battery. I regret not buying the eBay battery for half the price of the iFixit one.

Yes. Li-ion batteries degrade at some rate - whether they are used or sitting on shelves. Read this:

I would be very skeptical of the conditioning

All of you believe in AccuBattery? You can look at the manufactured date and get an idea. Most of it are assumptions:

These are as good as stock market predictions.
Most of these apps first use 'so much battery to monitor' what happens in the OS. Thereby they contribute to lowering your battery time.
(yes, many use these - but does not mean it is scientifically accurate).
Uninstall all crap; use phone for weeks. Then you get yourself an approximation for your phone + your apps + usage!
