I have had my current mobile for four years. I had a very good fast charger which broke so I had to buy a new one. I bought a cheap one from a little independent shop not a phone shop and it wasn't a very fast charger so I went back to the shop to see if they could give me another one which I thought would be a bit quicker but it wasn't and the second one didn't charge anyway.
I was quite concerned because the phone was losing charge and I have no landline anymore so the mobile was by only phone and I thought if there was an emergency I need to have a working phone. In a panic I went to the EE shop just see what they could do about it and they said it is probably the phone not the charger because the phone is four years old and when it gets as old as that the charge gets slower and slower. However when I went to the Independent shop to buy the charger they told me that because he was a cheap one it wouldn't be very fast and if I wanted a faster charger I would have to pay a lot more which they don't have and I would have to go to a mobile phone shop.
I am wandering whether the EE shop told me it was the phone rather than the charger because they wanted me to purchase an upgraded phone and if I actually did buy a more expensive faster charger it would work properly I would be charging up my phone much faster. I do not buy my phone and have a SIM only contract I pay a contract over two or three years and so that's what they were trying to get me to do for an upgraded phone so I'm not quite sure what the situation is I wouldn't think that the EE shop would lie about it just to get me to upgrade my phone
