So I don't have to pay the manufacturer a fortune to open the cover.

If the company put a decent size battery in there in the first place you wouldn't need to replace it.

Size is irrelevant, batteries have a limited lifespan.
What use is a 1 mAh battery even if it lasts you a decade.

My point is it doesn't matter if the battery lasts long enough between charges, it will still chemically die after 4 years.

Battery life is mostly determined by charge cycles or in extreme cases how it is treated. Most don't keep their computers 4 years anyway.

And the time limit of 4 years. You can't buy a rechargeable, hardly ever use it, then expect it to work 10 years later.


So no point in buying it then if it only last 4 years is that what your saying ?


Duds occur no matter what.

when you find a dub reject it don't try hiding it inside a phone or laptop.

Probably not possible to detect all forms of dudness.

The more you test for .....

The more it costs.

yes, it's cost samsung quite a bit.
Maybe the saving on testing or spending money on a betteryh battery didnlt pay off this time, better luck next time perhaps.


Phones and laptops don't wear out, they become obsolete, at the same rate.

What do you mean by the same rate ?

"the same rate" is a common enough English phrase.

But it doesnt apply equally to all computers.
Look at a 4 year old apple laptop and a 4 year old lenvenoe and check the prices.

yeah sure maybe better designed is luck in your world.

I hardly think major manufacturers are using badly designed batteries.

Almost right. "I hardly think"

Perhaps you could explain why samsung had such problems then.

http://www.wired.co.uk/article/galax...-what-happened

Batteries made by Samsung's SDI group were too small at one corner, causing negative electrodes to be bent and increase the likelihood of short circuiting. Separately, batteries from third party provider Amperex Technology Ltd were incorrectly welded. Points left on the batteries were able to penetrate protective insulation.

Why do you expect a 100% success rate in everything?

I don't.

How many of apples iphone7s have exploded or have had bad batteries ?
