Review on AICase Stylus Pens For Touch Screens Computer Accessories & Peripherals by Brandon Daughenbaugh

As stated in the specifications, "Fast charging and super long standby】 15 hours of continuous use, 60 minutes of charging, 30 days of standby. It automatically enters sleep mode. after 30 minutes idle, to save energy." 60 minutes charge works fine. 30 days standby, NO CHANCE. It's not true. After using this pen on my iPad PRO 2020 for the past few weeks, this pen has a very short battery life. It lasts 20 to 30 minutes under heavy use.If you use the stylus extensively on your ipad, this stylus will not be reliable.Maybe for someone who uses it very rarely.
