Battery issue, Charger issue or?

I have a Samsung Galaxy S3.

A few days ago I noticed the battery draining rapidly out of nowhere, it went from a full charge to dead in 2 hours.

I put it on charge when I got home using the wall charger and it took 26 hours to fully charge my phone from dead to 100 per cent battery.

I used the phone to go online and the battery was draining, I looked at it and it was draining 5 per cent every minute or so.

Now when I try to charge the phone either with the wall charger or USB charger it takes over an hour to charge 1 per cent.

I am planning on buying a new battery tomorrow but wanted to ask before I did so in case it is something else causing it.

Does anyone have any ideas on what the problem could be? (as a side note I turn off wifi/mobile data/location etc when not in use, close apps down when I have finished with them etc)

    This happened recently with my wife's S3.

    We bought a new battery from amazon and now all good. It was an Anker battery, currently £10.

    If you remove the battery from the phone does it appear swollen in the middle?

    It's pretty obvious that it's not the charger issue.
    It's the battery or the phone or both.

    First buy a new battery Anker as advised .
    If that is the same try a factory reset but add no further apps and test .

    Hi, I have the same problem and have the Galaxy S3 - my provider beginning with V shall not exchange it for a new hand set and am now onto my 5th like for like reconditioned mobile! They keep exchanging but shall not provide me with a new one... I switch it on and all seems fine for a week or 2 and then same thing happens battery drains really quickly.... charging for hours! One bit of advice I got was to make sure the hand set was switched off at night time and to then charge. This has improved the battery but not to 100% it has been a total night mare and I am paying for a service that I am not getting. My husband has now written a letter of complaint. The provider is such a large company that they just pass me to person to person and basically get no where! They can however charge me over £330 to end my contract or I could pay £230 for an upgrade - neither of which I a m prepared to do! Total nightmare and apparently this is happening to the S3s all of the time!

    P.s I have bought a new battery and charger and still the problem remains!

    Network will still work if you put the sim in another phone thats the network service you are paying for .

    The turn off at night to charge is nonsense .

    The same problem on 5 phones almost defies the law of greater numbers .

    I do use an older Samsung charger which had a lower charge output than my S4 charger.

    In the hope that it charges it slower so less heat and a longer battery life. The first battery was one of the dodgy ones that swelled up.
