Agreed. I think the Chinese have figured out for themselves that
skimping on battery QA is self defeating. My experience with two or
three dozen non-oem phone, camera, and cordless tool batteries is
that problems are very infrequent. I've certainly never had an
extreme failure.

I've found the opposite with two phones and one camera. Replacement
batteries (always described as genuine) have failed within 3 months.
Batteries from another (random) supplier have since lasted well, so
far. There was practically no price difference between the good and
bad batteries.


Agreed. That's why I took caution in choosing a supplier.

I have replaced a few batteries in mobile phones, satnavs and tablets,
and bargains from eBay and Amazon have mostly been nothing more than
frauds. They recycle parts cleaning to look like new, not manufacture -
a process with expensive tooling and QA, not all can afford. Have a look
on eBay for factory tours.

The work (and risk for me) in disassembling a fiddly expensive phone,
and having not to repeat that exercise again in a short time, makes it
worthwhile.

Releasing double sided sticky tape from the back of a charged Li-Ion
phone battery without damaging it and letting out the demon wisps, is
not my idea of fun. Even worse if an overcharged damaged battery is
boating. So the less time done with me wielding dental floss approaching
the target in bomb disposal mode, the better

Then some would say I'm a bit of a wuss....


Many of my phones have had removable batteries, but I didn't have any
trouble replacing the glued-in one on my wife's iPhone a few months ago.
I think I have probably only bought batteries from Amazon or eBay, and I
do select based on feedback. I can only repeat that I have never had
significant problems. I think I had one camera battery that did not last
particularly well. I had a phone once that started giving short battery
life, but I was able to show that this was the phone, not the batteries,
by swapping genuine and clone batteries back and forth between this and
another phone of the same model.
