I've built a bunch of Lithium Ion packs (nothing huge, the largest was 10 KWh, but still you don't want to mess that up, that's 1000 cells in a 40S25P arrangement), none of them go that low under load. If your cells drop down to 2.0V under load that's not a normal condition, either you are discharging your cell at more than the 2C or so that is normally specc'd (which you are welcome to do but it will cost you in lif…

You'd be surprised the peak current demand of modern smartphones. AVERAGE current demand (not peak) of a Snapdragon 8 Gen 2 can hit 16W for short periods of time. At 3V, that's 5+ amps out of the battery. Worse if you account for efficiency, and even worse if you account for other power draws such as camera, display, etc etc. Running at 3-4C for short bursts is not out of the question.

That I readily believe. But in a well designed system (designed for longevity) you'd never see such discharge currents in a sustained manner and even short bursts are better served by capacitors (charged at a lower constant current) close to the consumer than by batteries. And that's why you'll see voltage regulators and large banks of capacitors right next to the CPU (besides compensation for line losses and stability of the supply, which with rapid wide load variations would cause all kinds of problems for the logic).

But in for instance a vehicle or an e-bike you'd rarely see batteries drained faster than the spec, not if you want to use your expensive device for a while.

These foldables are a great demonstration of why the screen diagonal is an unintuitive metric. This device has a 5.8” screen when folded, and a 7.6” screen when open. Looking at those numbers, it doesn’t sound like a very big difference. Yet anyone can see that the 7.6” screen is twice as big as the 5.8” one! The diagonal only made sense for TVs because the aspect ratio was fixed at 4:3 (and later 16:9). It shouldn’t…

Even more so for us Europeans where both the diagonal and the inches are not relatable. Double confusing.

Many people don't even know it's a diagonal, they just associate the number with having seen the object in real life. You could call it a TV with a size of "16 leafs" or "354 planks". Neither the value or the unit has any meaning.

I just don't understand who wants these foldable phones, especially at the $1799 price point. I guess a use case is wealthy frequent travelers who don't want a separate device with a larger screen to watch movies/videos on the go? Someone help me out here.

>I just don't understand who wants these foldable phones

The problem is that they're using the wrong fold. I want my screen to EXTEND outwards. I don't want to go from one screen to open yet another screen. I want it to intuitively either extend, or allow me to fold OUT my content, not in.

Could you imagine if Amazon made a fire phone unfolded that’s opens into an e-ink kindle? I would own that.

I dream of a clamshell e-reader, with dual 7 or 8" screens, that reads in the traditional two-pages-at-a-time kind of book orientation. It seems a no brainer to me. It would keep the fragile e-ink substrate safe, while being more ergonomic and allowing you to have twice the screen real-estate without ending up with the terrible reading experience with too-long-lines that you get from current large-screen e-readers.

On a similar thread, I saw a post today for a Phillips 24" monitor with an e-ink extension display: https://www.anandtech.com/show/18859/philips-reveals-dual-sc... its pretty nuts.

I couldn't find any pricing info, but I would test drive one for a work setup if I had the chance.

Huh? My left thumb can reach the button just as well as my right one when using one hand. This is on a iPhone SE

It’s mounted on the right side on Pixel fold, like on Samsung S10e and Samsung fold. See “sustainability” paragraph. https://www.theguardian.com/technology/2022/sep/05/samsung-g... https://i-guim-co-uk.cdn.ampproject.org/ii/w820/s/i.guim.co....

Oh yes that looks very unfriendly for lefties

I just spent $400 on a Ryzen 5650, 32GB RAM and 1TB NVMe. The screen sucks compared to my work MacBook (most do) but it’s faster and has more cores

The Ryzen 5650 is certainly not faster than the base MacBook Air M2. The 5650 does 1848/7191 in Geekbench, M2 2560/9566. Heck, even the 2.5 years old M1 is faster at 2322/8243. I fell for the Ryzen laptop hype and bought one around the time of the M1 that was supposed to be about as fast as the M1. In practice it started throttling pretty fast and the performance was way worse than the M1. Also, the battery life was…

I have an Intel MacBook. It does pale in comparison to the M-series. I bought it from eBay as “used, like new” and bought the memory and nvme myself for the best deals I could find (they’re cheap these days)

No sign of battery issues is huge, I'm still rocking my 3 year old Pixel 3a and recently replaced the battery, it was a night and day difference. General slowness/lack of responsiveness, half day battery life. Been like that with all my other smart phones since 2013. Would love my next phone to go on year 4 with no sign of battery degradation (although in lieu of that I'll take an easy to replace battery).

> night and day difference > slowness / lack of responsiveness Are you saying that replacing the battery improved your phone's responsiveness? I knew there was a throttling thing with iPhones but hadn't heard of anything outside of that.

My wife's Nexus 6 would only play games at what appeared to be 2 fps unless hooked to a charger after three years. And those were just some 2D puzzle games, not COD, so I imagine other 2D apps were not running at full speed too but it was extremely apparent on games.

> I had a 55' TV and I also bought an 85' TV. > I had a 24' monitor. I also bought a 34' monitor So huge! I don't think I could even fit a 24' monitor in my house. How would you get it through a door?

Good job. Nit picking. Have a cookie. No wonder you miss the bigger point in life focusing on irrelevant details

Is there a place that has empirical data on this stuff? Like what battery factoids are still true with the latest devices or not? I would honestly love for phone manufacturers to outright build in some software to build in best practices if they actually exist. Don't let me charge to 100% at first or something!

AccuBattery is an Android app that gives battery usage statistics and more detailed readouts from the OS w/r/t battery condition and charge/discharge behavior. Their help portal has a research summary explaining their sources (the most recent of which is from 2010, so battery tech has likely improved in some respects but it's still a useful reference point): https://accubattery.zendesk.com/hc/en-us/articles/210224725…

Chargie is another solution for the problem and links to researches https://chargie.org/
