Is my mobile phone battery bad?
My phone switches off a lot and I have to charge it up, but the battery
indicator on the display always shows as fully charged. Would the battery definitely be at fault? How can I test it ? (it has four contacts - and is 3.6v ni-nh) I have test equipment. Thank you, David |

The battery indicator only shows the voltage of the battery which can stay high, but as the battery ages, it can no longer give much current and when you make a phone call, the phone tries to draw more current than the battery can sustain, the battery voltage sags and the phone shuts down. If the phone doesn't shut down as easily when you've just charged it, then it's most definitely due to a bad battery. If, however, the phone just switches off randomly or when you shake it or twist the battery, then you probably just have bad contacts. Try cleaning them all with alcohol or somesuch. On some phones also bending the contacts outwards can help. -- Arto Rantala |

When a battery reaches the end of its life, the charge remaining indicator can get very unreliable. It can go from fully charged to not enough to power the phone before the indicator is updated.

I've seen a few of these with those symptoms, caused be faulty components in the phone, but it could equally be a bad battery. Dave |

So I guess it's ancient in most peoples eyes. Anyways, I have completed the freeze, thaw and recharge process as mentioned by myself on this thread. Fingers crossed! Waiting for a normal battery run down. Thanks, David Is it a Nokia by any chance?
