How to Check the Most Accurate iPhone Battery Bottle

This guide explains how to check the Most Accurate iPhone Battery Bottle, with clear steps, practical tips, and important checks before you begin.

1. Check the battery level of your iPhone with the battery status feature (iOS 11.3 or later)

From iOS 11.3 and above, Apple has equipped a battery status check feature to help users monitor and control the battery capacity of the iPhone to avoid sudden shutdowns or more dangerous short-circuiting, exploding. To check the battery level, do the following.

Step 1: Go to Settings => Battery.

Step 2: In the Battery section, click Battery Status to view information about your iPhone battery. In the Maximum capacity line displays the level of your battery bottle. Specs like the picture below means the battery of this iPhone is 5% bottle.

2. Check the battery level by software 3uTools

If your iPhone is running software version iOS 11.3 or below, we can not check the battery level by using the battery status feature because Apple has not integrated that feature. To check the battery on iPhone, we will use 3uTools software (to run 3uTools, you must have iTunes software installed in the computer).
