iPhone 7/Plus Does the iPhone battery meter need re-calibration?

[Ev0d3vil]

Just swapped to a new battery for my 7+, but the battery seems to be draining like my old battery, do i need to do a re-calibration of some sorts?

Should have fully charged it before turning it on I think. Either that or it’s a poor quality battery, or fault with the device in another area.

Or maybe the battery wasn't the problem? Battery drain isn't a matter of calibration, it's a matter of usage. Use the information in the battery settings to see what apps are responsible for the usage.

A new battery is usually factory calibrated.

There is no accurate calibration that you can do. You have an underlying problem or got a bad battery (unlikely in this case).

From what I’ve learned using the iPhone over the years, I’d let the battery fully drain, charge it up to 100% without removing the the lightning cable/wireless pad and after it is fully charged, perform a hard reset and the battery should not drain as fast. I do this when a new iOS version gets loaded on my iPhone. Hope that helps...
