If it's out of warranty, no harm in opening it up to test the battery. Disconnecting the battery for a few seconds, then reconnecting may help anyway.
You say you've tried various chargers... I presume at least one of them is a fast-charger?
I assume you've tried holding the power button down for 30 seconds, releasing, then again for 15?
