Brian Heater, TechCrunch:

Those $29 battery out-of-warranty replacements Apple promised are now available for impacted users with an iPhone 6 or later. The company was initially aiming for a late-January timeframe in the States when it first offered up the discount, following blowback against its admission that it had slowed down older model phones to maximize performance.

“We expected to need more time to be ready,” the company said in a statement offered up to TechCrunch this weekend, “but we are happy to offer our customers the lower pricing right away. Initial supplies of some replacement batteries may be limited.”

No word yet on the timing of the battery health iOS software update.
