Re: "Would you rather have shit battery time?" @d3vy
"And nowadays if you bought something labelled as "genuine Samsung" or "genuine Apple" the chances of it being genuine are slim."
So true. Needed new batteries for a Lumix camera and a Samsung phone. Reading Amazon feedback, many/most "genuine" batteries were shown to be not only fake but faulty.
Instead I bought a Hama camera battery on the basis that this is an established German camera accessory brand. For the phone I bought from a supplier that had countless positive reviews (battery brand I'd never heard of before but which has been working well for 6 months so far).
It's a scandal that enormous firms like Matsushita (Lumix), Samsung and Apple refuse to police their brand names, to the detriment of their customers. Of course it would help if they charged a reasonable price for replacement batteries, sold from their own sites or official retailers.
Better still batteries should be standardised across brands (they already seem to be pretty similar in format) so that one could buy them like torch batteries, picking a trusted brand like Energiser, Duracell, etc via regular retailers. This would go a long way to reducing the number of devices which are dumped when the battery fails.
Let's not even mention phones with fixed batteries.
