Charge smarter. Sleep better. Keep your battery healthy. Most phones and laptops today come with built-in battery protection features that limit charging — but they don’t always work the way you expect. These systems often wait until your battery hits 100% before stopping, or they rely on your daily habits, which can be unpredictable. They’re a step in the right direction — but they’re not enough. Chargie goes further. It’s a hardware and app combo that gives you full control over how and when your phone charges. By letting you choose your own charging limit and schedule, Chargie keeps your battery cool and unstressed all night — which significantly extends its lifespan. How it works: 1. Order the Chargie USB device from chargie.org 2. Plug it between your regular charger and your phone cable 3. Install the Chargie app and connect via Bluetooth 4. Set the maximum charge percentage you want and the overnight level your want your phone to stay at. 5. Set the morning top up level and time you wake up. Sleep soundly — Chargie handles the rest Why it’s better than stock solutions: - Works with any phone or laptop, not just select models - Doesn’t rely on vague algorithms or machine learning - Actively controls the power flow, not just battery software - Automatically resumes charging before you wake up - Reduces battery heat and wear throughout the night by reducing charging power or increasing it adaptively With Chargie, your phone battery lasts longer, your device stays valuable for resale, and you help reduce electronic waste — all without changing your habits. Shipping is fast worldwide so you can start protecting your phone right away. Chargie hardware sold separately. Bluetooth required for app operation. ## Key features - Set custom charge percentage limits - Schedule overnight charging - Control morning top-up levels - Works with any phone or laptop - Actively controls power flow - Reduces battery heat and wear ## What do users think of Chargie?

Constantly pesters about bluetooth access. The hardware cutoff threshold does not save, immediately resets to default if you connect with bluetooth which is incredibly annoying. Many places in the app, including in the hardware cutoff threshold, it is impossible to read the full instructions, it ends with “…” with no way to expand to read the rest. A shame that such a great product is ruined by such horrible user interface. ### 3/5 — Great idea - poor app *2026-07-25, version 2.7.4* I bought the USB-C Chargie as I wanted to extend the life of my iphone battery. Unfortunately the app is plagued with issues. Aside from some features being poorly explained (looking at you hardware only page), but the app constantly loses connection to the Chargie so sometimes it doesn’t start charging and lets the battery drop low or it fully charges the phone. I’m sure some of this is IOS background limitations but then don’t advertise your product as compatible if it really isn’t. Also when enabling hardware only mode, if you open the app to check on things, annoyingly it will often switch automatically to app mode. Like the title says, great idea but definitely issues currently. ### 2/5 — Been using for years *2026-05-24* Well, it worked great for a while. Then iOS 26 seemed to have messed it up. I do not use schedules. I always want my phone to charge to 85% and stop. But, now it will display charging paused, yet continue to charge and i wake up with it at 100%. I have tried turning off every setting. Sometimes it will work, but most times it ends up overcharging. Guess I’ll have to get a new phone that can manage this on its own. As for the UI: The new look is too overdone! Everything is too big! It no longer fits on one screen, and whenever I try to scroll up or down I end up accidentally changing the charge limit. I have an iPhone 14 Pro Max, running standard zoom level. Please shrink the whole thing down! The battery image doesn’t need to be that huge. ### 1/5 — Used to work on iOS *2026-05-24* I don’t know what the update that they did. I have had these for about 3-4 years. Haven’t always worked on iOS devices fully. Usually, I have to go into the app to make sure that it connects to the correct charge (I have three of them , two USB A and one USB-C ) and then it would work. Ever since an update of late no matter what I do, plug it in open the app, make sure it’s connected before I leave it. It never stopped charging my iPad until 100%. It loses Bluetooth connectivity. Would not recommend anymore. The device I spent money on and they ruined it with an app update, so much for trying to save my battery. ### 3/5 — Was Marvelous, Now Only Works Intermittently *2026-05-16* Bought two Chargie-Cs at the same time thinking I would keep one in reserve just in case. The one I hooked up initially worked great, wonderfully, for the first 2 years. Then suddenly, and with mine it happened once iOS 26.0 was onboard, it stopped working consistently. It would always connect and find my phone with my settings intact but 50% or more of the time would permit my phone to charge to 100%. As of today, it has permitted 100% charge every night for the last week. So, clever fellow that I am, I got my spare out (never used since purchase) but discovered I couldn’t use it at all. The app simply wouldn’t find it and connect it. I followed the in-app instructions to the letter. No dice! I tried 3 days in row after subbing my original back in. Still no luck. So again, clever fellow that I am, I used the in-app ability to send a note to the developer asking for help. Sent the request 3 times over a week. No response at all. 3 stars for the time it worked. Would be 5 stars if it hadn’t crapped out on me, if the replacement had worked, or if the developer had answered my calls for help. For now, avoid this device and app like the plague. If an eventual app update solves the problem or the developer ever does contact me with a fix, I will change the rating to 5 stars because when it worked it worked beautifully! ### 1/5 — Horrifyingly bad after update *2026-05-12, version 2.7.1* Used to work most of the time. After the last update, less than 10% of the time. It just goes straight to 100% or anything else you didn’t set. lol. What a joke. ### 1/5 — Broken again *2026-04-28, version 2.7* Yay the developer added CarPlay pass through (unclear if it actually works - doubt it) but your schedules are erased (again!) and even when you add them back you’ll wake up to a phone that hasn’t charged because they ruined everything else in the app - again! Stop messing with the app! Just give me basic functionality that actually works! ### 1/5 — Stopped working reliably *2026-04-26, version 2.7* The app either loses connection to the dongle (and never reconnects) or it does not update the charging state. This results either in the device (here: iPad on iOS 16), charging constantly or to not charge at all. This worked just fine before the big app overhaul. Right more, the dongle is completely useless. ### 1/5 — App keeps declining *2026-04-25, version 2.7* This app just gets worse and worse the more they update it. It’s to the point it doesn’t even work properly anymore. Despite the settings or schedule you set it just charges to 100% when it feels like it. Defeats the purpose of having a chargie. ### 3/5 — The new update won’t work *2026-03-16, version 2.6* The app won’t charge after update iOS 26. Half of the time won’t “find the device” and even it find it. It would drop it later. This morning my phone is dead. Don’t do it, just charge to 100%. The iPhone will keep it at 80 for you sometimes. ## Frequently asked questions about Chargie ### What does Chargie do? Chargie is a hardware and app combination that gives you complete control over how and when your phone charges. By allowing you to set custom charging limits and schedules, it helps to keep your battery healthy, reduce heat and wear, and significantly extend its lifespan. ### How does Chargie extend battery life? Chargie extends battery life by preventing overcharging and managing the charging process more intelligently. You can set a maximum charge percentage, preventing the battery from constantly reaching 100%, which can degrade it over time. It also reduces battery heat and wear throughout the night by controlling the power flow. ### Is Chargie free to use? The Chargie app itself is free to download and use. However, the core functionality requires a separate hardware device, the Chargie USB device, which must be ordered from their website. ### What devices are compatible with Chargie? Chargie is designed to work with any phone or laptop that uses a USB charging cable. Unlike some built-in solutions, it is not limited to specific models, offering a universal approach to battery management. ### How do I set up Chargie? To set up Chargie, you first need to order the Chargie USB device from chargie.org. Once you have the device, plug it between your regular charger and your phone cable. Then, install the Chargie app, connect via Bluetooth, and set your desired maximum charge percentage, overnight level, and morning top-up settings. ## Version history (last 5 releases) ### 2.7.7 — 2026-08-16 - One-time schedules now delete themselves once they are done: as soon as the scheduled time passes with your battery at its target, or half an hour after the time if it never got there - Holding at the base level overnight no longer turns into charging all night. To keep iOS from suspending the app, Chargie switches power on for 30 seconds every half hour. When the app was woken in the background, the timer that ends that pulse could never fire, and the pulse stayed on for hours - Background wake-ups now run on the same thread as everything else, which is what let the pulse get stuck. A pulse older than a minute is treated as over regardless - Extra: Added Chargie Fleet support ### 2.7.4 — 2026-07-14 Fixed issues related to older Chargie C Basic devices and CarPlay mode power interruptions. ### 2.7.3 — 2026-07-09 ### Scheduled charging survives the app being killed - Chargie now keeps a standing reconnect request on your last device whenever a schedule needs it - If iOS terminates the app overnight, this reconnects — and relaunches the app — the moment your device is reachable again - Closes the gap where a killed app with power intentionally cut couldn't get back in to resume your schedule ### Stability Fixes - Fixed a bug where the app's own background wake-ups could silently disable themselves after the first overnight check - Background wake-ups no longer require charging to be active — they now fire correctly during maintenance-mode power cuts - Fixed charging commands occasionally being sent twice per decision (start/stop/schedule/manual toggle) - Fixed several background-task completion bugs that could crash the app in the background or shrink its future background time - Fixed memory leaks in BLE scanning, the scanning screen animation, and two popup views ### 2.7.2 — 2026-05-19 - Fixes several engine issues related to plugin detection, charge scheduling, connection stability. - CarPlay mode now forcefully defaults to OFF - some users had overcharging issues because of it. ### 2.7.1 — 2026-05-04 - FIxed issues that prevented charging to stop when CarPlay was on. - Fixed CarPlay issues from previous version. ## Apps similar to Chargie | App | Rating | Price | Category | | --- | --- | --- | --- | | [Battery Charge Alarm](https://appshunter.io/ios/app/battery-charge-alarm/id1482503198) | 4.6 (2,924) | Free | Utilities | | [Battery Health - Charge Alarm](https://appshunter.io/ios/app/battery-health-charge-alarm/id1557004936) | 4.4 (552) | Free | Utilities | | [Battery Life - check runtimes](https://appshunter.io/ios/app/battery-life-check-runtimes/id1080930585) | 4.6 (33,586) | Free | Utilities | | [Amperes Battery Charging Lite](https://appshunter.io/ios/app/amperes-battery-charging-lite/id1253789580) | 4.2 (555) | Free | Utilities | | [Amperes 4: Battery Charge Info](https://appshunter.io/ios/app/amperes-4-battery-charge-info/id1245475416) | 4.4 (644) | $2.99 | Utilities | | [Battery HD+](https://appshunter.io/ios/app/battery-hd-plus/id331453283) | 4.5 (2,714) | Free | Utilities | ## More apps by Ovidiu Sandru - [Woo Obsession](https://appshunter.io/ios/app/woo-obsession/id6446248004) All apps by Ovidiu Sandru: https://appshunter.io/developer/1559014919 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
