I've bought OEM replacement P7P batteries precisely identical to the manufacturer-installed battery. I've been through two replacements in just a couple months. They either have inadequate connector metallics (which renders a battery error symbol) or it putts out after a few weeks.
This recent batch of three were all fully comped by the seller just due to AMZ shipping issues, but the first replacement just suddenly went into infinite repeat power cycles after a month of use after installation.
Upon initial installation, the battery was already charged to 50 percent, so I fully charged it with the 30-watt wall adapter and let it stay plugged in for a few hours more, then fully depleted it to shut-down, then kept it plugged in since, except for days out with it. A few weeks later, it's unreliable, and two days later, it's constantly rebooting.
The interesting thing there is that when I paused the GOS bootloader screen, it was stable until I let it continue as usual.
What the butt?!
This one, I'll just try the battery manual's installation care advice of depleting the battery three times with extra charge time (even though "that's outdated advice"), then I'll keep it plugged in.
