### 5/5 — Appreciate the hard work

*2025-07-28*

I really like the device and it seems to save my batteries. My iPhone 16 Pro Max is still at 100% and it is nearly a year old. I would suggest instead of monitoring the charging of the battery, you might include more information about the life of the battery along with savings that might occur by using the device. The current graphs do not seem to be very useful. I have an external usb-c device to get voltage and current.

### 1/5 — Trash app and device

*2025-06-14*

Every two days the device needs to have a software update. How do I learn about that? Because when I plug in devices, nothing charges until I update it. Waste of money, wish I never backed it.

### 1/5 — Power metrics and setting feature missing

*2025-03-08*

The % charge and battery power setting and metrics are missing in the app. What is depicted in the screenshot in the App Store is not present actual app. On the Liion Power website they say they are working on those features. Given that those key features when bought over two months ago and what they advertised the product and app is deceptionly presented.
