Samsung Galaxy S2 charges slowly

[Huong Ninh]

My galaxy s2 charges so slow, it takes about 5 hours to full battery. I charged directly and turned apps off. Help me!

Are you charging directly from a wall outlet, or from your computer? USB charging via computer takes longer than from the wall, since the current is lower.

If you're charging directly from a wall outlet, are you using the original charger, or a 3rd party one, or a charger from a different device? Not all chargers deliver the same amperage, so if you're using a charger with a lower output, your phone may charge more slowly.

It is likely a charger issue, see this thread: [APP] Skyrocket Charger Test - xda-developers and try the app!

I'm charging directly from a wall outlet and charger's original. when my phone's new, it just takes about 2.5 hrs to charge!

Chargers and charging cables can fail or become faulty. Can you try a different charger & cable?
