What's New in Chargie

2.7.7

August 16, 2026

- 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

Battery Saver

I was able to stream 80gb a month of music videos off of a Galaxy S21. At 3.5 years of keeping the battery at 55% its battery health is at 92% and I have 92.9 cycles over 1,338 days for an 887% efficiency. This is according to AccuB battery Pro. The phone is dropping more and more between 5g speeds, so it’s now being replaced with an iPhone Pro for better privacy. Also, at 92% battery in the Galaxy I am noticing some degeneration of the battery below 50%, meaning 92% left is a noticeable hit in performance. It also leaves me wondering if repeated use at 55% is always a hit in the same area of the battery? In the upper ranges the Galaxy lasted over a day the few times I tested it since activating the new iPhone Pro. Also, I have been using Chargie with my iPhone 15 for 2 years now without any issues, but the Apple API does not allow for the detailed specs to to be gathered that Android users can get (at the expense of privacy in some cases). Apple’s built in cycle count works differently from what I can tell.

I’ll be damned - it works

About a week ago the new update FINALLY fixed the issues and my iPad charging has flawlessly stayed consistent. Granted it took years of not working to get here. Happy.

Good Device, Bad App

Infuriating app. I just want to set to hardware mode and forget it. 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.

Great idea - poor app

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.

Been using for years

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.

FAQ

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.
