iPhone 6s Plus Battery Indicator at 1% After iOs 15.4.1 Update
I recently updated my iPhone 6s Plus to iOs 15.4.1 and about a week later last night it kept notifying to change to low power mode and battery indicator is stuck at 1%. I restarted the iPhone and even though battery is at its lowest it is not shutting down. I have been taking care of battery usage, charging when necessary so there's no reason for this issue.
