Odd Dyson fault

I think google are working on that, because the android kernel is heavily patched from stock, it's not unusual for a brand new phone to run a 2 year old kernel, so even if they pick a longterm support version, they generally have to support it themselves as it's run out before the phone is 3 years old ... they're trying to get closer to mainline ... maybe they'll edge it to 4 or 5 years ... my Nexus 5x felt like it had a year or two left in it.

I think you would have to define 'Left on charge'?

From a user POV it might be considered 'on charge' because it's plugged into the mains and the charging light is on but it might not actually *be* charging the battery at that point.

In the old days, basic car chargers would come with an ammeter so you could determine, from how much current it was supplying, how charged the battery was.

'These days', few would understand what that meant (and partly why they don't fit engine temperature gauges to some cars nowdays).

So, any reasonable battery charger these days is likely to either show a 'Charged' LED or the led change from flashing (charging) to solid (charged) and the charging current cut off.

It may well continue to monitor the battery voltage and *if* it should drop back below a certain threshold, it may provide a top-up charge. However, the self discharge rate of these modern cells is quite low and so it wouldn't be doing so very often or for very long (and we don't know what charge level that actually is).

My most sophisticated / computerised muti chemistry and voltage charger allows you to set all these values and give full BMS of up to

Not just satellite batteries but any scenario where the primary goal is to prolong battery life.

In most systems however, where the battery capacity is limited by size, weight or cost, lifespan has to be a compromise between useable capacity and said lifespan.

eg, Some people push their batteries to the (safe) extremes because the cost of that is considered acceptable.

Radio modellers are one such example.

When I was a sponsored RC electric car racer the maximum speed and duration of the car was set by the ability of the battery to give 100% of it's charge of the duration of one race, because even if the batteries only lasted 25 cycles at that usage (instead of maybe 1000), that could still be one complete season (you typically ran multiple battery packs) and was just part of the 'cost'.

Ooops

Mine is an ordinary V8 but it has two filters - one that drops in from the top and one that twists in at the back. I'll start with the former. .

Will experiment.

Personally I think Biros are more useful.

Hmm, I may have my model wrong then, having a quick Google it might be a V6 Animal (like I said, it's not here). ;-(

Don't experiment too hard, in case yours doesn't come off that easily but I'm guessing it *should* come of, for cleaning and whatnot?

If it doesn't (without a tool) what if you look into the main suction port. Can you see if it's clear etc?

TBH, the stuff I pulled out of mine didn't seem particularly dense but it did definitely make the machine cycle.

Holding out against mobile phones is getting rare. I was a late adopter but eventually sold my privacy in exchange for utility, in the usual Faustian pact with Google.

Oldies have been rapidly catching up with youngsters:

I struggle to find things to do with my iPhone. I removed mail and twitter from it, and while I use WhatsApp, I just just as well not.

The clamshell I used before was perfectly adequate.

More fool you. I don?t even own a biro anymore and only use a sharpie to write the brew number on the cap of the beer I have just bottled now.

Yeah, I only know one person that stupid now.

Some of the youngest of my mates little kids don?t have them.

Don?t need to sell any of it with an iphone.

Then you actually are that stupid.

I removed mail and

I just bought two red ones.

I've mved nack to a 'feature phone' after having a series of Android smartphones, I find it *much* handier in many ways:-

It runs for several days on one charge

It has real buttons to press, in particular for answering a call

It's very robust, no big screen to break (and I did break the glass on one of my Moto phones)

It's not worth much and not attractive so is unlikely to be stolen

... and it *does* have 4G and WiFi calling.

Meanwhile I think I shall have to turn off the fingerprint business on the iPhone, it doesn't work half the time.

So do plenty of iphones when used like you use that phone.

Even easier to answer an incoming call with a voice command.

Plenty of life proof cases.

But useless when you need to check on whether a particular store has what you need in stock when out and about or to check the hours they open, or whats open on xmas day etc. Or check the road conditions during flooding, or navigate to somewhere you arent familiar with etc etc etc.

Then you need to get to get it fixed, mine works perfectly every time unless I have wet fingers and leaves entering secure passcodes for dead.

Yes. By coincidence I have exactly the same symptoms here - although it is not air filter related (see other posts) yours might be.

I was about to buy a replacement battery since it is getting on a bit but I did a few experiments first and got surprising results.

I have access to multiple chargers. Mine outputs 26.00v under load and the battery refuses to charge with more than a token 15s worth of use.

The other unit outputs 26.20v and the thing works perfectly on that! This is incredibly unexpected behaviour.

I can also test them on different raw mains and the Dyson supply is a carefully regulated 26.xx v with input voltage from 230vac to 245vac. (which happen to be the local mains at two different locations)

Can you measure the output voltage of your charger accurately?

Or try your unit with another charger with the same rating...

I intend to recharge mine from a bench PSU set to the right voltage to establish that the thing really is so sensitive to voltage.

I used to think that until I moved to a smartphone (I needed it as a PDA). I now find it is more powerful and more efficient than my iPad, that 4G is on the whole excellent and I can check news, surf net, read emails and much more. In fact it is faster than my PC for reading emails. I would never go back.

Think it's going to depend on how good the 'charger' is.

Had an Acer laptop which fried the battery even with modest use. So ran it without the replacement - and only fitted it when needed.

Current HP is a few years old but battery still fine. And it's left on most of the day.

Nevertheless my home laptop's battery is dead after only about 4 years, and we've had a couple of batteries swell up and die at work.
