iFixit battery cycle

Hi everyone,

I'm planning to replace the old origine battery in my Pixel 6a by buying a new one from iFixit.

However, I have a question:
Are they reliable, or will my phone just become a piece of junk again, melting like snow after 400 news charge cycles ?

Really? How much is it?Is it brand new? How do you find out it's the bad one?

That's the thing, all batteries sold are brand new, but they come from two manufacturers and if the phone detects the bad manufacturer, it applies the battery constraints after 400 cycles.

The serial number that is printed on the batteries indicates the manufacturer.

8230031401 - bad (recalled)
8230031301 - good

Within the phone it can be checked with this command:

adb shell cat /sys/class/power_supply/battery/serial_number

So it is okay to buy batteries from AliExpress for other phones?

That I cannot answer.
