Is it bad if your battery health is 95?
It’s not unusual to see iPhones that, after one year, still have a battery capacity of 95% or above. The reason is a type of fail-safe: Apple builds its batteries with excess capacity, meaning that it doesn’t actually use all of its potential operating power when its Battery Health states 100%.
Why is my battery health at 96%?
Your phone reports this as “96% battery health” because your battery can now only hold 96 percent of the original capacity. Supposedly, this number approximates battery degradation and therefore battery status.
Is 94 percent battery health good?
100 percent: Your battery is currently supporting normal peak performance. 95 percent: This iPhone has experienced an unexpected shutdown because the battery was unable to deliver the necessary peak power. 79 percent or less: Your battery’s health is significantly degraded.

The meter should read between 13.5 and 14.5 volts. If it is in that range, the alternator (if it has a generator) is good. With the engine not running and the ignition in the off position, disconnect the ground (negative) battery terminal and connect a test light in line with the ground cable and the battery negative terminal.

Why does my battery keep losing its charge?
If you do not have a sealed battery, remove the battery caps and top off the battery “cells” (about 1/2- to one-inch from the top of the battery) with distilled water. A dirty battery top can “leak voltage” between the terminals draining the battery when not in use.
