Alarm by empty battery is to quiet

[GTriderXC]

As I got an answer that alarm clock can not cry for help as the battery dies, I'm updating the description. No system application should cry for help. It should be sysyem itself!

The problem is:

A PRESENT LOW BATTERY NOTIFICATION IS TO QUIET.

It should be loud enough to wake us up! If You remind yourself the Nokia phones... it was impossible not to hear the battery dying. It should be impossible too especially in a buggy phone with UT, that without a special reason can drain 50% of the battery within a few hours (there are bug reports about it).

--------------
I think i saw already somewhere a bug report about unreliability of the alarm clock: if the battery goes empty or the phone switch off for some reason, alarm clock will not ring.

It happened to me that my phone turned off by itself into my pocket or battery went empty for some reason that nobody can explain. I saw such issues also on the mailing list.

If a low battery kills the alarm then I'd propose that the alarm starts to ring before the battery is 0% and the phone switches off no matter how much time left till alarm should ring.

The present notification by low battery at 5% is so unnoticeable that there could be no notification at all.

Thanks for taking your time to report this bug.

Clock app cannot read the battery charge level, so it would not be able to react if the battery is low.

Please take a look at this bug reports: bug #1420169 and bug #1317860 If they are fixed, you're problem should be resolved.

If I remember right, Nokia phones was able to fire alarm even when
switched off. That's how it supposed to be.

My old Siemens S4 did this too, spending all the rest of the energy in making noise. This will not help you if you have no chance to recharge. And if you can not switch off the noice, you will loose the rest of energy which you could spent in some last emergency call. DO NOT implement this.

@Aleksander, yes but it is not only about the alarm clock. It is also about a phone call that You will not be able to answer if You don't know the battery is about to die. This is a bug #1420169.

@Matthias I do not think the idea is wrong. Wrong can be only the implementation. If the battery is 3 or 5 % You will not be able to do anything more with Your phone apart from switching off. If a phone starts to cry at20% You are right. Making a noise like a Nokia 3210 doesn't cost much energy! And one more thing: I don't know how about Siemens but in Nokia You could disable this notification. You will probably admit that this notification is very important in case when You set an alarm clock that is supposed to wake You up. At 5% a phone could switch for exaple to half-standby mode-disable the screen, turn offline, play a screaming warning signal and wait for an alarm clock to ring.

We handle with a small Linux computer! We can set some cron tasks etc. so it doesn't have to be an alarm clock. First of all we should be able to deactivate this notification and second thing is what I already wrote: at 5-7% remaining Your phone turns into a brick anyway. A sound notification doesn't do much harm to battery as long as the screen stsys off.

I use my BQ E4.5 18/24 hours every day as Wifi AP to connect my laptop
and I use it every time consuming the battery to 2% before connecting
the power supply. From 5% to 2% you can do still a lot of usage, in any
case an emergency call to 112 or whatever the number is in your area.
IMHO, spending (the last) energy in noise does not make sense, apart of
a pop-up as we have right now.

Re/ using the BQ as an alarm clock to wake-up, I do this too every day
but when it comes to important things, like catching an airplane, it is
always a good idea to setup a real clock, even a mechanic one.

There is also a bug that tells us how reliable the 5-2% are:-) But even if we don't care about the bug at the moment as I just read Your description, I can tell You here and now how Your battery is gonna behave in a few months if You let it fell to 2% every day.
Your comment reminds me about another bug I posted: Available SMS notification sounds are to short and quiet. I posted it cause if we are with the E4.5 on the street, You can't hear the loudest and longest notification that this phone has to offer. One user answered me that they are fine, cause he was fed up with all these 100 notification he gets every day. So now the question must be asked: for whom are we building a phone? For people who work in an office and get a 100 e-mails every day or for every user, also a runner and cyclist who want to hear a message? Same thing is about battery. You prefer that Your phone dies unnoticed. I bet there are also many users as me who would like to know that their Activity Tracker app or the bug mentioned above, swallowed whole battery and we should turn Activity Tracker off before it drains these last 2% that allows me to call 112? We should always study more cases before making a decision and do not look only from own's side of view.

I do not think we can call "progress" if through the last 12 years my mobile phone waked me up and now suddendly I need to carry a mechanic alarm clock with me:-) As we see from Your comment an alarm clock isn't very important or crucial for You. Just as SMS messages in other bug. But for many people sms, calling and alarm clock are the most important things in a phone. If they do not work, we do not need a wifi AP function.

I do not think it is a good idea to read SMS or e-mail while walking or cycling. I see this all day people with the eyes in their smartphone and shocking with others in the traffic. Re/ alarm clock, GtriderXC should read more carefully my words. I said, I use the BQ E4.5 all days for this. And only for security reasons I would use a second one in certain situations. I did even the same when I still was using my old Siemens cellphone.

Re/ this issue: if someone implements making noise with the rest of the energy, please make it with an option to switch this power-drain off.

[GTriderXC (gtriderxc)]

Sure it is not a good idea. Once You hear a message arrived You should stop and read it. If You don't hear it, You have to pay attention to Your phone every few minutes if everything is ok: If I received a message or is perhaps my battery already empty? Having a reliable notifications let's Your concentrate on Your life. Not on bugs, that drain the battery.

:-)
