Pattie - Battery Pet

Pattie. Your battery's daily habits, with a face.

A cute battery companion that watches every charge, learns your patterns, and shows you with one mood how kindly you treated your battery today.

WHY PATTIE?

iPhone batteries last twice as long when you keep them between 20 and 80 percent. Apple knows this. But Apple won't show you your day. You don't know if today was kind or hard on your battery. You can't get an alarm at your favourite charge level. On iPhone 14 and earlier you can't even set a charge limit.

Pattie fixes that. Every charge gets logged. Every hot moment, every deep discharge, every overnight stay above 80 percent. Then Pattie turns it into one number, one face, and one tip you can act on.

WHAT PATTIE DOES

Today's Battery Stress. A score from 0 to 100 for how kindly you treated your battery today. Built from time over 80 percent, time near empty, heat events, and discharge spikes. The lower the number, the more your battery hurt.

A mascot with five moods. Pattie shows you how the battery feels: healthy, charging, charging fast, stressed (low or hot), or critical. Tap, drag, long-press, it reacts.

Pattie's week. The last 7 days as colored dots, green for healthy, yellow for moderate, red for hard. See your trends at a glance, no charts to read.

Charging history. Every charge gets logged: start time, end time, duration, percent delta, fast-charge flag, peak heat. Plus heat events when iOS reports a serious thermal state.

Smart Tips. Personalised advice based on your real charging patterns. Too-long overnight stays. Fast-charging past 80 percent. Hot charges. Near-empty habits. Healthy streaks. Pattie only talks about what you actually did.

Charging Goal Alarm. Pick any target from 0 to 100 percent. Pattie pings you with sound the moment you cross it. Foreground or background, it always rings.

Live charge at a glance. A Lock Screen Live Activity that stays fresh every few seconds while you're charging. Battery percent, charging speed, goal progress, all without unlocking your iPhone.

WHAT PATTIE IS NOT

No accounts. No sign-in. No analytics. No ads. No third-party SDKs. No tracking. Everything stays on your device. Forever.

HONEST DISCLOSURE

iOS does not let third-party apps read battery health percentage, real-time temperature in degrees, or the official charge-cycle counter. Pattie works around this with derived metrics from public Apple APIs. The Stress Score and Smart Tips are best-effort approximations, not Apple's official numbers. Use Pattie as a habits companion, not as a medical-grade diagnostic.

iPhone running iOS 17 or later. Pattie is free. No subscription. No paywall.
