Is my mobile phone battery bad?

Chances are the battery is moving in relation to the contacts that allow the circuit to be broken momentarily. Take the phone to your provider and see if they will replace it. I have two friends at work that went through the same thing.

Hi Mike, If the battery contact was lost for a short time then I should loose the time on the display, but I don't unless I purposely remove and replace the battery. I have found a forum where someone details putting the battery in a freezer for several days then recharging it. I am giving this a try as I tend to not use the phone for extended periods and think this may have caused the problem. Thank you, David

Are you talking about a cordless phone for home use, or a cell phone? I get the feeling you are talking about a cordless. I have never seen a cell phone that loses anything when the battery is removed. If the battery indicator always shows a full charge, then there are a couple of possibilities:

1) The battery is discharging very quickly. (replace the battery) 2) There is some internal fault with the phone itself. (repair or replace entire phone)

It won't hurt anything to try freezing the battery as you suggest, but I doubt it accomplishes anything. Good luck.

As my subject heading i.e "mobile" in my part of the world this means what you call "cell" phone...

If it only switches off when you make a phone call, it's probably because of a dead battery. 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.

It's certainly possible for a bad battery to cause this. 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. Andy Cuffe

In my part of the world it's customary to say "thank you" when someone tries to answer a question you posted, not respond with snippy retort...

My original post included a heart felt "Thank you". Thanks for pointing out the lack of thanks in the above. Was just a forgetful oversight on my part. Regards, David

Is it a Nokia by any chance? 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.

It's a Sagem mw930. 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
