Mobile phone question

[glee]

@Beckdawrek

I’m curious, @glee, what caused you to get a cel phone, now?

Two reasons:

• companies keep asking me for a cell phone number
• UK landlines are going away in a couple of years

P.S. my phone doesn’t take calls from females (it’s an incel phone )

• UK landlines are going away in a couple of years

Really? How long has this been planned?

Depends on your device: in its features you can choose either to only charge it up to 80%, then it stops charging at 80% and tells you so. In some models it charges to 80% if that’s your choice and tells you 100% when it stops. These are older phone models.

@Saint_Cad

thought that when it displayed 100% to me it really was only 80%

Depends on your device: some phone types allow you to choose charging up to 80% and tell you so when charging is finished. Some mostly older models allow to choose charging up to 80% but when charging is finished show 100%.

Sorry, editing error, my post shows twice, I didn’t manage to delete the first one.

I should have been more accurate - here’s the actual position…
From this site UK transition from analogue to digital landlines - GOV.UK

Communications providers in the UK are replacing the technology they use to provide fixed telephone networks (landlines). For most customers, the upgrade is expected to be complete by January 2027.

In November 2017, the telecoms industry announced its intention to retire analogue telephone networks such as the Public Switched Telephone Network (PSTN), which provides many analogue telephone services..

It sounds like you would still have the option to have a “landline” phone, in the sense that you can still have a wired phone sitting on a desk or a table, though it won’t be the old analog twisted-pair phone line (what we call POTS in the U.S. – Plain Old Telephone Service), but would instead be a VOIP (Voice Over Internet Protocol) phone, and would connect via an internet connection.

Yes, that’s how I understand it.

I wish I could’ve used you as a role model for my parents, who got a smartphone way too soon after retirement and now spend all their time looking at short videos of cats and fake news and fake cats… sigh.

In that sense I’m not a role model - I relax by using my computers to look at youtube videos of:

• farting cats Cat fart better than you (tiktok)
• farting hippos Try not to Laugh…Hippo has the World’s Biggest FART!!!
• farting in elevators Elevator Farts 1 | Jack Vale
• prank farting Ultimate Fart Prank: Turdy Tornado | Hilarious Reactions!

um … now I notice a common theme

I’ve recently bought a Nokia mobile phone.
It’s simple to charge it up (e.g. the phone displays a message when the battery is full), but within a week or so the phone doesn’t receive calls and appears to need recharging.

Is this a common problem?

I was almost the first responder to this thread, and would have asked you to clarify what you were asking, but I decided to let other people handle it.

My question would have been were you concerned about the length of the standby time (thinking it was too short) or the existence of a standby time.

All electronic items that aren’t completely “turned off” are still using energy. You won’t notice this with items plugged into an outlet (unless you closely scritinize your power bill). With your microwave it may be only the clock drawing power, so tiny trickle. Your desktop computer in sleep mode draws more, it has to keep memory refreshed and the CPU running at a minimum level watching for you to touch a key or jiggle a mouse to tell it to ramp back up to full power.

For anything running on a battery you are going to have to care more about standby time. If you have a laptop/notebook computer, unless it is completely turned off it will be drawing power from the limited battery supply for the same reason as the desktop. And so do tablets. The CPU has to be running at some level 100% of the time it is turned on to any degree at all, RAM has to be kept fresh, and buttons, touchscreens, and fingerprint readers have to be powered at all times waiting for a wakeup call. The selfie camera, too, if the device supports facial unlock.

Cell phones add another level of power drain: they have to be constantly monitoring the cellular radio for incoming calls. And it has to be periodically transmitting on the cellular radio to “ping” the tower, saying “Here I am.”. The amount of power that uses depends on the signal strength between the phone and the tower: whenever the phone says “Here I am.” and it doesn’t hear an acknowledgement from a tower it ramps up the power and tries again: “I SAID HERE I AM!”.

On top of that, a cell phone will have additional constant power drain if the WiFi and/or Bluetooth radios are turned on, and if the GPS reciever is turned on.

Thanks for replying!

I knew the phone would be drawing power, but didn’t consider the monitoring and transmitting you mention.

Well done, SDMB!
