Button push indicator?

Hi there.

I've got a hardware issue with my Nexus 5... the famed powerbutton stick issue.

Well, I'm better at hardware than software so I have a question. Is there a way to program or use an app to have an indicator for whenever the power button is activated? Such as having the LED light on the N5 light up whenever the power button is pressed? Or maybe have an indicator on the screen of the phone? The LED would be preferable, as it is clearly visible even when the screen is off.

This will help me see if the power button sticks and try to save it before it reboots. I've already minimized it's use by using a proximity sensor app to wake.

Any other help would be great!

Thanks

[Q] Hide Status Indicator Icons Using Root?

Is it possible using root to somehow hide or remove the status indicator icons (e.g., priority, disconnected) on an android wear watch?
These icons really ruin the look of watch faces when they're on, especially with an always screen on enabled watch.

Battery charge indicator defect

This is a defect I have observed all the way from Android 1.6 to Android 5.1.1, and I cannot understand how it can still be there without ever getting repaired.

The problem is that the battery indicator shows a positive number, for example, 8%, although the battery is actually at 1% and the phone will shut down any moment now.

This alone would be bad enough, but it gets worse. After the phone shuts down on its own, either due to an immediate, disorderly power cut or by performing an orderly Android shutdown, Android should have registered the obvious, namely that the battery is empty.

However, it does not. When I connect the charger and start Android, it still shows 8% charge. I have just tested this again three times in a row with at least one orderly shutdown on my latest phone, a OnePlus One running CyanogenMod 12.1, and it never went below 8%.

How can this be? How difficult is it to program that after a shutdown due to an empty battery and a restart one minute later the battery is indeed empty? It is not physically possible to charge a battery from 0 to 8% in a minute. It would explode if you tried.

Do the charging electronics not store and provide information at least about the very recent charging history? And can the phone not evaluate the battery voltage, which it measures? At least when there is no load on the battery for a little while, its voltage and its temperature allow to determine precisely whether the battery is empty. Why does the phone not do that?

Needless to say, this defect is damaging. To know how soon the phone is going to shut down is one of the most crucial bits of information for every phone user. To show the user 8% while already shutting down is beyond stupid, it is derisive.

I have something in my head that I call the idiot bells. They ring when I notice idiocy in my surroundings. And whenever I see the phenomenon described above, they ring loudly.

Can anyboy who really knows how Android and the charge electronics work explain what is happening? Or is it just the ordinary idiocy that we have to keep living with?

Do not suck nonsense replies from your fingers. If you don't know anything reliably and in detail, keep quiet.
