Use this guide to replace the battery in your iPhone 16 Plus.

You'll need replacement back glass and battery adhesive to complete this repair. If your replacement battery does not include adhesive, use [product|IF145-458|stretch release battery adhesive|new_window=true] instead.

iPhone batteries are rated to hold 80% of their capacity for up to 500 charge cycles, or roughly 18–24 months. If your iPhone needs to be charged more often or runs slower, it might be time to replace the battery.

This iPhone uses a battery adhesive that requires an electrical charge to loosen it. [link|https://support.apple.com/en-us/120671|Apple's repair manual|new_window=true] recommends connecting a 9V battery for 90 seconds, but you can use a power supply or a power bank at a 5–20V output instead—the time required to loosen the adhesive will vary.

The guide below uses our VoltClip with ***a USB-C Power Delivery (PD) power source***. This can either be the [product|IF145-494|FixHub Portable Power Station|new_window=true], a [product|IF145-542|USB-C PD power brick|new_window=true], or some laptops/smartphones. ''Not all USB-C PD power sources support 12 V'' (the FixHub Portable Power Station does). If the source doesn't support 12 V, the VoltClip will operate at the next lowest voltage—usually 9 V. This voltage is still sufficient to debond the adhesive. If you're using a different method, follow the guide normally and supplement your power source's operating procedures during the necessary steps.

After completing this repair, you may receive warnings about your replacement part and lose access to battery health data, but your new battery will otherwise work normally. As of iOS 18.1, battery health works with both genuine and aftermarket replacement batteries.

After your repair, run [link|https://support.apple.com/en-us/120579|Repair Assistant|new_window=true] to reset the battery metrics.
