You might not use them as hard as I do. I'm running a business off mine, and it gets a lot of charge/discharge cycles. Often deeply discharged, too, which is not at all good for the life of the battery.
Besides! My comments were based on a 30 year history of using "mobile" phones. I still kind of preferred the bag phone I had back in the early nineties. I could rebuild my own battery packs out of store-bought nickel cadmium C-cells. That was back before they even had cellular service, and you needed to have enough power to make it to the only mobile phone tower in town. My 5 watt bag phone NEVER had a dead zone until I was about 25 miles out of town. After that, you had nothing.
I've always put a premium on having replaceable batteries in the phones. I could do snow removal for two days straight, and just keep popping in a charged battery when I needed it. While they are certainly putting in premium batteries these days, they cost a fortune to have them changed at a specialty store. I've had that done several times, and suffer anguish every time the manufacturers stick me again with their planned obsolescence.
