Introduction
Use this guide to replace the battery in your iPhone 16.
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 and the iPhone 16 Plus use a battery adhesive that requires an electrical charge to loosen it. Apple's repair manual 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 uses the VoltClip along with the FixHub Portable Power Station to release 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. Run Repair Assistant to reset the battery metrics.

Thats some crazy stuff going on with the battery. Gonna need the same method to loosesn the back glass somehow. Maybe a hidden Positive and negaitve terminal in the sim slot where a special insert would loosen the glue with power being sent through it
