Frequently Asked Questions
Does Kawaii Emoji Battery upload my data?
No account is required, and your sticker and theme choices stay on your device. The App is free and ad-supported, so it uses Google AdMob, Google Firebase and Adjust, which may process a device advertising identifier to serve ads and measure performance. Full details are in our Privacy Policy.
Why does the app ask for the Accessibility Service?
The optional Accessibility Service is used only to draw your customized emoji battery overlay in the right place. It does not read your screen content, passwords or other apps, and nothing is sent off your device. You can turn it off anytime in Settings → Accessibility → Kawaii Emoji Battery.
How do I set an emoji battery sticker?
Open the app, browse the sticker gallery (Trending, Animals, Cute and more), and tap a sticker to apply it. Use the toggle at the top to enable or disable the emoji battery, and visit the Status Bar screen to place a sticker in your status bar.
How do I add a battery widget?
Long-press an empty area of your home screen, tap Widgets, find Kawaii Emoji Battery in the list, and drag your preferred widget layout onto the screen.
The emoji overlay disappears after a while. How do I fix it?
Some manufacturers (Xiaomi, Huawei, Oppo, Vivo, Samsung) aggressively close background apps to save battery. To keep the overlay running, exclude Kawaii Emoji Battery from battery optimization: Settings → Apps → Kawaii Emoji Battery → Battery → Unrestricted / Don't optimize, and lock the app in your recent-apps list.
How do I manage permissions?
Go to Settings → Apps → Kawaii Emoji Battery → Permissions to grant or revoke individual permissions. Note that some features depend on the "Display over other apps" and Accessibility permissions.
How do I see fewer / non-personalized ads?
You can reset or delete your Advertising ID in Settings → Privacy → Ads, and decline ad personalization when the consent prompt appears. The App remains free either way.
Is there a charge for the app?
No. Kawaii Emoji Battery is completely free to download and use. There are no in-app purchases or subscriptions.
