Is it just me, or are Lithium-ion battery manufacturers making lower quality products?
Just wondering. Your thoughts appreciated!

I know, it's a hot summer day. And so it shouldn't be a surprise that my smartphone is hot after leaving it on the charger for 15 minutes.

But it never got hot on my old smartphone, which is seven years old now, and still has standby mode lifetime of eight days, and 'heavy use' lifespan of almost eight hours. And I haven't replaced the battery on that one since I bought it seven years ago. And it certainly hasn't been left on standby at 40% the entire time – it's been on and connected almost constantly! (Exception: the few times I had to reboot it.)

So why is it that suddenly batteries seem unable to have the same sort of lifespan they did back then, that posts like these are now more than I care to mention? Why do newer batteries seem to 'age' and 'explode' faster, so that extending lifespan suddenly becomes a big issue?

    The LiON batteries are the same quality as before — it's just that battery tech has not kept pace with smartphone tech.  Essentially, our high powered smartphones are being run by battery technology which is 1990's vintage.  Years ago, I could use a cell phone for at least a week, with heavy usage, before really needing a charge.  Today, I can't make it a full day without having to charge up my smartphones.  Now with a lot of smartphones running 3/4G services — the batteries cannot keep up with the power draw and will get hot.  Short and sweet — battery technology needs to improve drastically in order to properly power today's technology.

    A new product is measured by it's quality, and not it's price.

    Hm, hot when charging is theoretically complete. There are a few options, but most of them are related to the way the phone handles the battery, not how the battery is made. Basically, if the phone keeps pushing amps into a full battery, there's gonna be heat.

    The heat is actually a radiation. I wonder if it is more a matter of Radioactivity, than design. 

    Maybe the company is shortcutting on the insulation used on Lithium Ion batteries, I don't know. I am much more familiar with Pile Lithium batteries.

    +Craig Perko Higher max load, yes. But that is discharging, not charging. What puzzles me is that they get hot during charging and after charge is completed (when they are theoretically in 'trickle' mode to not overheat or overcharge the battery), while the old phones don't.

    Charge cycle for heavy use is equal on old and new devices: they both last the same amount of hours on charge, so I'm not charging any more or less frequently than before.

    I'm under the impression newer phones have much higher energy use, and require batteries with both higher max load and higher total available energy.
