Cosmo Communicator - Android / V22 is out.

CPU SPIKE / HIGH DRAIN / HIGH TEMP ISSUE - maybe resolved in V22

I've only been on V22 for a day, but my issue with certain apps intermittently causing CPU spike seems to have disappeared.

I had an issue where occasionally the temperature near the rocker switch would go very high.  Battery drained much faster.  This could go on for hours if unnoticed.  Opening/unlocking and going to the desktop, and then scrolling back and forth between desktops was very jerky whenever this happened.  The issue would often go away just by closing and re-opening, but I also found it disappeared as soon as I opened GSamBattery app.  I noticed in GSam that CPU would spike to constantly 100% during these occurrences.

(I installed GSamBattery to try and track down what was going on, and then once I discovered it has temperature alerts, I set that up to detect whenever this strange CPU spikes occurred)

Over time I discovered that there were a couple of apps that shortly after using them, this CPU spike event would occur much more frequently.  However, it didn't necessarily happen right when a particular app was just used.  I could have my phone tucked in a pocked for a half hour and no problems, then suddenly the issue starts.

Since V22 I have tried using those apps to see if I could get the issue to recur, and so far it hasn't.  So that's good.

Oh well, the description is exactly what I have now, started somewhere after upgrade to V22 and now on V23 it's still there. Even with Safe Mode it was still reproducible. Cosmo is unusable now :-/

Cosmo Communicator - Hardware / Battery life

« on: July 10, 2020, 03:21:20 pm »

Hey all,

Got my Cosmo late last year, and of late have noticed it draining through the battery a LOT faster than previously.

I use my Cosmo a LOT. Dual screening infront of the TV, car sat nav (the Planet car kit is the most solid car cradle I've ever used), Tidal streaming etc. etc. I don't leave it connected to the charger, and generally charge to 80%. Up until about a month ago, I could easily get a day plus before needing to charge. I have normally used the supplied Cosmo charger to charge it, but also have a USB C car charger (Belkin), a Huawei charger (also USB C, from my old Nexus 6P), and a Lenovo charger (USB A).

Now.. it's draining a LOT faster.

AccuBattery suggests that Firefox, phone calls etc. are all taking a lot more power.. though given that the native battery app doesn't report on individual app usage, I'm going to guess that AccuBattery guesses based upon active process + BMS overall drain reported, and perhaps it's something else sucking the battery dry faster.

I'm running v22 of the firmware, and run with CODI and keyboard backlight off most of the time (unless I want to use NFC or the second USB port, it stays off). Upgrading CODI was the usual hell (Airplane mode, NFC off, BT off, WiFi off, DnD on) and it's still telling me to update the firmware even though I'm apparently running the latest version.

Have I just hit the cycle limit on the battery - or is something else afoot?

Edit: It seems, besides the fact that there's never been proper per-app power utilisation built into the Cosmo, that its battery estimation calibration relies on it more frequently being charged to 100%. After I charged it using a slightly slower charger to 100%, and I unplugged it, it sat at 100% for around 30 minutes of active use before I stopped using it and went to bed. When I woke up, the rate of charge decline was also significantly slower. This suggests the battery management system is cutting some corners and can lose track of where non-extreme charge states are.

I have the same, now charging it during the day as it reaches 15% by 4pm. Also recently it rebooted and after the reboot was showing 1% battery left (although it was ~50% before), so maybe it's just inaccuracy in reporting?

Cosmo Communicator - Hardware / Turning off each day

Mine has similar behavior since V22 (I was on V19, then V20, then V22 and now V23). It's not really turning off, it's just hanging and then timing out so display turns off and it feels like the device is off. Just today I had to reboot it like this more than 10 times. Tried booting in safe mode and it's still the same. Before it hangs, the interface is trying to refresh for a few seconds and then it's not responding, CoDi is reacting to touches, but doesn't pass anything to OS (i.e. fingerprints/PIN entries/etc.) and the only way to return it back is to reboot.

Cosmo Communicator - Android / Fullscreen browser?

Using Naked Browser, it comes with a bunch of keyboard shortcuts and works in fullscreen by default.
