I began noticing a few months ago that the battery in my Samsung SIII smartphone was not lasting nearly as long as it did when new. I was getting barely a few hours out of a charge.

I was in Toronto in early June for several conferences, and was using my phone more than I usually do to keep in touch with local relatives and friends, read my email, check Twitter and Facebook, etc. At home I do many of these things from my office computer, so hadn’t noticed as much how weak the phone battery was getting.

I had an hour to kill over lunch one day, and tried four or five cell phone retail outlets in downtown Toronto, and none of them had a battery for the SIII. It’s not that old, but old enough in the rapid model turnover of the cell phone world that none of them could be bothered to stock batteries for it.

I returned home, and put up with the shorter and shorter battery time, until the last day or two the battery wouldn’t take hardly any charge at all. I could leave the phone plugged in overnight, and have less than a quarter bar of battery power in the morning.

About a week ago I ordered a new battery from an online battery shop, but yesterday and today, I could not get more than a minute or two out of a charge. So I searched for battery specialty shops in Burnaby, and came up with Battery World on Boundary Road. I called them, and they had four SIII batteries on hand.

So I drove over this afternoon and bought one. Staff encouraged me to pop the non-Samsung branded battery into my phone and make sure it fitted properly and powered up. It’s nice to see a full bar of power on the screen again, and it’ll also be nice to have a backup battery when the one I ordered online arrives.

The new generic battery also has a tish more  capacity than a stock Samsung battery at 2,300 vs 2,100 MaH, but I haven’t had the opportunity yet to see if that realizes more uptime per charge. That’s only around a 10% increase, so I doubt if I’ll notice a difference.

It’s amazing how one becomes addicted to technology. If I leave the house without the cell phone, or if I’m out of juice, I feel naked. And I’m not a power user by any means. I might make and receive half a dozen to a dozen calls on my cell per week, and about the same number of texts. I am using it more for email and GPS location finding than I used to.

Oh, yes, I’d also like to thank Samsung for making batteries easy to change. Just pop the back cover off the phone by sticking a fingernail in the slot, and there you go — easy access to the battery, SIM, and microSD memory.
