What's new in 1.4.1
Unsigned build — sign it with your own Apple ID before installing. https://github.com/ResistanceTo/MiniWatts#install
修复:
• 滑动时每秒卡一下:在 iPhone 15 Pro 等机型上,任何页面匀速滑动时大约每秒会顿一下,插不插充电器都会出现,现已修复。原因有几处叠加:.
• 表盘中间的数字滚动效果和弧线动画会被放到 CPU 上绘制,页面滚动时每一帧都要重画一次,占用了大量主线程时间。.
变化:
感谢反馈这个问题的用户。.
Fixes:
• Scrolling hitched about once a second on every screen, charging or not (reported on an iPhone 15 Pro). Several causes added up:.
• The dial's rolling number and arc animations were drawn on the CPU and redrawn on every scroll frame.
• The floating meter (Picture in Picture) rendered a frame every second even when it was not open.
• Every tab you had visited kept refreshing in the background once a second, and the visible page rebuilt its navigation bar and toolbar on every refresh.
• Sensor reads now run off the main thread.
Changes:
• The power reading on the dial no longer rolls and its arcs no longer animate; they update in place like every other reading.
• A tab returns to the top when you switch back to it.
Thanks to the user who reported it.
About
MiniWatts:
English · 简体中文.
An iPhone battery and charging monitor built on Apple's private APIs. It reads the phone's own power-management sensors — the ones iOS uses to run the charge — and shows what the charger is delivering, how much of it reaches the cell, where the rest goes as heat, and what every temperature sensor in the phone is doing while it happens.
Sideload only. Private APIs mean this can never be on the App Store — you sign and install it yourself. There is no network code of any kind: nothing it reads leaves your phone.
Install:
Download the latest MiniWatts-unsigned.ipa from.
Apple ID — Sideloadly, AltStore, SideStore and Xcode all do this. A free Apple ID works; the app then expires after seven days and you re-sign it.
