iPhone 11 Do new iPhone batteries have an adjustment period?

[robes1]

I'm wondering if the batteries on new iPhones usually take a few days or charges to adjust and break-in? My new 11 battery is doing funny things, and I'm wondering if it's just something that needs time to sort by itself.

If you could explain the “funny things ” a bit more in details then we might provide better information.

It’s never a bad idea with a new battery to drain it to about 2% and back up to 100% two or three times when they are new. That may help the stability

 

[now i see it]

The battery in the iPhone doesn't need to be "broken in". The charge status indicator function might. The charge status estimator occasionally needs to know where the zero and 100% charge level is so it can estimate the values in between. Over time it can lose calibration if the battery never gets too discharged or fully charged.
Two full cycles can recalibrate the charge indicator to help it be more accurate, but doing so is harder on the battery.
Personally I never do it. I haven't run my iPhone down to nothing ever and the charge indicator is still ok enough for me

Nope. Doesn't help with new iPhones unless something is wrong.

With your new iPhone, things should be fine within 48-96 hours of setup. If not, there is software/hardware at play that's causing issues.

Apart from having to download data from cloud and doing some indexing I don’t think you should see huge difference in power consumption.

Also keep in mind that we tend to use new devices a bit more.

I don’t believe there is a break in period for batteries.
