iPhone 3GS shuts off and won't start untill connected to power


My iPhone 3gs shuts off randomly and won't start till connected to the charger.The battery % reflected is always healthy.

I have shown it to a known analyst (not to the apple store as it is jail broken).He first did a fresh installation of the custom OS 4.1 - no results.He then checked the motherboard and other hardware for fault - no results.

He is suggesting , battery replacement might help , but there isn't any guarantee.

Help !

Shikhar Hasija, nobody can ever say with a 100% certainty what it is unless one has the phone for diagnostics. I most certainly would try to restore it if you think that it might be software related . The number one thing I would do, before anything else, is to replace the battery. "If it shuts off randomly and won't start till connected to the charger "would be what I base this on. Hope this helps, good luck.
