@yasamoka first I'd like to thank you very much for this valuable information and i agree with your point 100% but also it could be a real genuine battery.
and you're thinking of buying a non-official
the battery has the htc logo and all the tags "ce,..." + serial numbers+... , so it looks official and I'll wait for a while before i MAY buy one .
They cannot simply be made to have more capacity for less mass of lithium.
It might be heavier but the increase in capacity isn't large so the weight increase could be unnoticeable (i didn't use a scale)
This can mostly be done by REDUCING THE THICKNESS OF THE WALLS THAT COVER THE LITHIUM CELLS. Meaning, the battery is more fragile. It can crack more easily (pressure or I guess heat). And when this Lithium is exposed to air, it can explode, burn, cause injury...
and you know that technology these days is a fast developing environment so i thought that it may be a new development in battery technology or fabrication.
Beware!
don't say that to me :-) , i've lost around 4000$ because of a single 7$ lithium-ion battery left on charge during the night (the charger was a simple power supply ) the whole room turned black and the contents into ashes :-(, from that accident till now i charge any unattended battery inside a metal box.
