Do You Lose Data When You Replace Iphone Battery. You may lose this feature. I personally decided to lose my iPhone-tinkering virginity and try it out on my wifes iPhone 6.
I bought my iPhone 7 in December of 2016. The very next day I realized how unusable my old battery had been making my phone. No replacing the battery will not cause any data loss.

That should be enough incentive for you to do a complete backup before changing the battery. If it does lose any data the backup will. Luckily iFixit sells. If not its 69 to replace the battery on an iPhone 11 iPhone 11 ProiPhone 11 Pro Max and iPhone.
