Battery Life Monitor: Drainn

I have this installed on 3 devices. It is always running in the background. It reports the battery level of all the devices but will only give a report on 1 device. The other 2 devices say ‘No Sessions’. The app could be useful, but so far, it’s just a battery drain.

In my last review I said that app did not sync between devices and MBA. It has finally synced but Mac is completely off. On my devices MBA showes as charging when it’s not and percentage completely inaccurate.

Would be 5 stars if Apple Watch (I have a series 5) shower battery level. As it is it only shows -100%. I have the latest app version.

I cannot get the app to open on my MacBook. It downloaded fine, but will not open. I downloaded it on my I phone and it started right up…. But not the case with MacOS. So can’t attempt to use “multi devices.” Both iPhone and MacBook have the most up to date OS updates (as of 5/25). Two days later….I’m updating my review. Everything is working as expected. The problem seemed to be that after I loaded on my MacBook it needed to be restarted. Prior to restarting and loading on your Mac be sure the blue tooth is also functioning between your iPhone and MacBook! The app is functioning perfectly and so I’m rerating my review to give the app a five star that it deserves.

Then it’s useless. Dev advised it’s fixed however my watch is still not seen. Wasted more time.

Please fix!

Can’t add a device and the help screens amount to little more than “who knows why it’s not working?” Don’t waste your time or money!

It works, but not with all Bluetooth devices. I tried 3 devices that do report the battery life to iOS, and only one of them showed up in this app. I noticed that the 2 that didn’t show up were Bluetooth headphones/speakers, while the one that did show up was a Bluetooth smartwatch (not Apple Watch). And the device that did show up didn’t update automatically, even when reloading the app. You have to remove and re-add it to show updated battery life.

非常感谢开发者，但使用中碰到了问题，我有多台相同设备，不知道怎么修改设备名称才能区分？另外好像不支持 airpods ?

The app isn’t universal though. macOS app is a separate bundle.
