Screen Test vs Battery Drain Check

Before you buy a used phone, before you sell one, before the return window closes on a new one — run Screen Test. Eight quick checks, one plain-English report, and a certificate you can actually show someone. No hunting through Settings, no cryptic diagnostic codes. Just tap through eight tests, answer honestly, and get a score out of 8 you can trust — or send. WHAT SCREEN TEST CHECKS Display • Dead Pixel — solid color fields expose stuck or dead pixels • Color Accuracy — RGB and white ramps reveal banding or tint • Uniformity — a flat grey field shows backlight bleed • Contrast — a fine checkerboard judges true black depth Touch • Touch — drag across the whole panel to find dead zones • Multi-Touch — press with several fingers to see how many actually register Geometry & Motion • Grid & Lines — a fine grid reveals distortion and bent lines • Response Time — a moving object exposes ghosting and blur HOW IT WORKS Start the guided run and Screen Test walks you through all eight, one at a time — with a short explanation of what you're looking for before each one. Answer "Looked fine" or "Something was wrong" and move on. The whole thing takes about two minutes. Screen brightness is raised automatically while a test is running and put back afterward, because a dim panel can hide the exact problems you're trying to catch. YOUR REPORT At the end you get a score, a plain-language verdict, and — if anything's off — a clear note on what to say if you're the one selling. Run it again later and Screen Test tells you what changed since your last check, so a new scratch or a new dead pixel doesn't slip past you.

Run guided battery drain tests for common situations such as idle screen-on usage, video-style playback, camera preview, navigation/location workload, gaming-style graphics and Personal Hotspot testing. The app estimates battery drain rate as % per hour, saves your results, compares tests, generates reports and gives practical optimization tips. Key Features: • Guided battery drain tests • 15, 30, 45 and 60 minute test durations • Real-life scenarios: Idle, Video, Camera, Navigation, Gaming and Hotspot • Estimated battery drain rate in % per hour • Battery Drain Score for quick result interpretation • Test history and scenario comparison • Charts for battery drain trends • PDF and CSV report export • Personalized Battery Optimization Plan • Practical battery saving recommendations Battery Drain Check is useful if you want to understand whether screen brightness, camera use, navigation, gaming, hotspot usage or other scenarios may be affecting your battery life. Important Accuracy Note: iOS does not provide third-party apps with direct access to battery current, voltage or hidden hardware power metrics. Battery Drain Check uses public iOS battery level and battery state APIs to estimate battery drain during controlled foreground tests. For best results, keep the app open, unplug the charger and run longer tests of 30–60 minutes. Battery Drain Check is designed for iPhone users who want a simple, visual and practical way to compare battery drain in everyday scenarios.
