- the S4 does not have the same charging algorithm as the Note3
- he was probably charging the S4 (which has different battery, charger and algorithm) at 1000 mAh or so (which was the most important point I was making, the 500 mAh are not 2x safer, are probably 4 to 8x safer, probably 20x safer than 2000mAh, that is not a linear thing)
- I think the S4 batteries had a certain defective batch (the media spoke at some point about it)
- there will always be a certain very small percentage of batteries that WILL go bad "no matter what", but that is usually exceedingly small if the charge process is done correctly.
