Oh dear god, please no
Now everyone will be blaming memory effect for everything
... "I installed 50 background apps, but only 49 of them use gps and 3g, and I'm not sure about the 50th, what's a bitcoin miner do? Anyway, now my battery doesn't last anymore??? Can't be the apps, must be memory effect!!"
... "I left my phone empty in a drawer for a month after I droppped phone in beer, and now battery life sucks. I opened up the phone and attached the battery to a car battery charger for a week, but that didn't help, so I borrowed a medical defibrillator and gave the battery repeated shocks, but memory effect is just getting worse and worse, halp!"
In all seriousness though, if you take someone very familiar with typical Li-Ion batteries such as LiCoO2 and similar, which we have in phones and computers, and tell them LiFePo4 is "just like" LiCoO2 but explosion-proof and lower voltage. it takes just one charge cycle for them to discover that LiFePo4 behaves nothing like traditional LiCoO2. When I first got a LiFePo4 batterypack I immediately noticed that charge behaviour was quite different. I couldn't find much litterature on the subject, except vague nonsense about "forming charge", and a somewhat competent looking research paper that used xray microscopy to compare slowcharged batteries to fastcharged batteries (where fast was on the order of 10 minutes), the findings being that fast charge caused less wear and tear.
Anyway, the point being that there's only one laptop ever (OLPC), and no phones at all, that have used a LiFePo4 battery. Considering how different LiFePo4 is from what's actually used in laptops and phones, this memory effect is entirely irrelevant for the normal user, even if the discovered effect wa s bigger than 1/1000th..
1/1000th is ldudicrously small anyways, considering battery meters in phones andsuch often are off by 20 percent or more... That also means it's nearly impossible for regular users to draw any meaningful conclusions from how they charge and use their devices, as there's no accurate measurement of drain and charge level, and the zero-point often jumps around from cycle to cycle.. Zero-point being the charge level at which the phone considers itself empty..
