Realme Charts Path To 10,000mAh Phone Batteries by 2026 (pcmag.com) 50
Realme plans to double smartphone battery capacity to 10,000mAh within its three-year strategic roadmap, the company said at tradeshow MWC on Tuesday. Current flagship devices typically offer 5,000mAh, while Realme's latest models already ship with 6,000mAh cells. The company expects to implement 7,500mAh batteries next year before reaching the 10,000mAh target, PCMag reported, citing the firm.

Everyone has a "three year roadmap", it's always three years in the future because that's when everyone has forgotten the empty promises. They have nothing to back this up, other than "we will add more battery".

A microSD card and headphone jack? Hey wouldn't that be something... But it seems like consumers actually enjoy having useful features removed. I's a sort of flex. I think they'd actually want a smaller battery and maybe some hooked barbs on the sides, so that it draws blood whenever you take it out of your pocket. They should put that on the roadmap.

No we don't. Mainly because the amper is something you can intuitively measure with gear that is visible and known while the Colomb is not. You cant convert to Colomb if you want, but it doesn't help anyone's understanding. There are electrical engineers the world over who have never worked with the unit of Colomb but daily have to deal with amps, volts and watts.

I think you missed the point, which is that, without knowing the voltage, milliamp-hours doesn't tell you anything. Is it at 5 Volts or 50,000 Volts. Big difference, no real clue from the unit used (there is from the context of what device it powers, of course, since it should be a 1 to 2 digit number for voltage and probably in multiples of approximately 3.6, but that's not really good enough).
Of course, aside from that, things like amp-hours and wattt-hours are kind of inherently stupid because amps are a

First, the unit under discussion is the Ampere-hour (on a side note, why does everyone defending the Amp-hour as a battery metric for the general public seem to think Amp or Ampere does not need capitalization?), not the Ampere. I just have to restart that the Ampere-hour is one Amp for one hour, or one AmpX3600 seconds. The Ampere is a rate, not a unit of measurement on its own. It is a ratio between the Coulomb and the second. Specifically 1 Coulomb/second. So that makes the A

The original point that I was trying to make was that more people have some kind of understanding of Ampere hours than Coulombs.
I agree with you that it would be better to state the amount of energy a battery can store. Assuming 4.3V a 10Ah battery would hold 43Wh=155kJ.

Yes. Just lower the Wattage, and the amp hours goes up. So if they're planning on lower-wattage phones, then they can achieve the target without changing batteries at all. Just use Watt-hours.

Why is the Columb 'simple'? Nobody cares about what 'charge' their phone battery has. With milliamp-hours you can roughly tell how long your battery will last based on a certain amperage draw, which is all people care about when it comes to the battery in their phone.

I guess I could ask you the same question. Everybody knows what an hour is, and most people know what an amp is. Almost nobody knows what a Columb is.

Most people have absolutely no clue whatsoever what an Amp is. They might know that their breakers are rated for certain Amps, but they don't know what that means except that a higher number is more (and only then because they are used to a standard voltage). Consumers don't generally care at all what units things are in as long as they can meaningfully compare them when there's a choice. The press release in this article is not for consumers anyway, it's for investors. So, sure, if all the technical adviso

If you asked 100 random people what an amp is, there would at least be a dozen (probably more) that would have a general idea of what it is (or that it at least relates to electricity). I'd bet $1k that one or less would know what a Coulomb is or even relates to.
So, sure, if all the technical advisors for the investors are working under the assumption that all phone batteries will be a nominal 3.6 volts, mAh can work as a unit.
Why would you even care what the voltage is? The battery is going to operate at whatever voltage it operates at, and put out X milliamps for Y hours.
So who exactly is the mAh for?
So you can estimate run time base on an assumed/average draw. The Coulomb is one amp-second. So

Which is different enough from

that it's almost the opposite of that statement. Basically you are saying that most people do not know what either an Amp or a Coulomb is. In which case, there's pretty much no reason, for general consumer consumption, not to use the Coulomb for battery capacity. Not that anyone should use either, of course. A more useful measure for the consumer for an amount of energy is the Joule. Basically, it's circular reasoning to say not to use a unit because people don't know what it i

I highly, highly doubt that given the context is a fire. Two problems with the measurements you're no doubt using. One is that you're looking at the electrical energy density of the battery. That's going to be a lot less than the energy density when used as fuel in a fire. The other thing is that, for the rocket fuel, you're looking at the energy density of the fuel when burned without consideration of the oxidizer that the rocket also needs to bring along.

Is there any technical challenge with increasing battery capacity? Aren't all the challenges business-related? Are consumers willing to buy a phone that is heavier in exchange for increased battery life? Phone manufacturers could make a 50000 mAh phone today if it would sell. Of course, no one would buy a 1 kg phone, since most users wouldn't use that much energy in one day and the extra weight just becomes a nuisance.
