| 609098 | 2007-11-08 02:26:00 | I have a nokia cell phone, had about a year? and now it seems to die or turn itself off? not all the time. sometimes a couple of times a day then ok for a few days. I had this problem on a Nokia 3105 after my game of Bounce crashed. I replaced the battery (just in case) and it didn't solve the problem. I ended up replacing it. |

| 609099 | 2007-11-08 07:59:00 | Dirty contacts on the battery and where they connect to the phone, wipe with a coarse tissue paper use isopropyl alcohol if you have it, do this to the contacts on the phone and the battery. This is a very common problem. Some people use the rubber on the end of a lead pencil. | zqwerty (97) | ||
| 609100 | 2007-11-09 03:37:00 | well here i am trying to get it go flat now....and still it is persisting....... but when i want the thing to work it dies...murphys law isnt it. beetle:lol: |

| 609101 | 2007-11-09 05:52:00 | First time it happened I had it sitting on top of a big speaker. I think it might be caused by where you put it, say by electrical appliances or something that generates an electro magnetic field like a speaker etc.:) No, that isn't the cause, you can't influence the charge on a battery in that way. Likewise the battery contacts, they are gold plated and so are those in the phone so they won't be oxidising at all, ever, though they can get dirty if you are particularly grubby, but you'd have to be a major health hazard to affect the battery connections. The problem is probably just irregular charging. We run a bunch of 2280's here and charge only when the battery gets down to 1-2 bars. Recharge is only a couple of hours so it's easy to keep them in good condition. Ours are 2-3 years old and still last 3-4 days per charge. Bear in mind that the battery will run flat faster if you are driving around a lot during the day because the phone will be actively transmitting every time you lose the signal or move from one cellsite coverage to the next.

| 609102 | 2007-11-09 07:16:00 | Beetle, I often deal with this problem (on other peoples' phones) and it is always as in my post above. This has been a problem since the first ones came out, especially when the phones are banged around, ie young peoples phones, throwing them to each other, dropping them on the ground, carrying them around in handbags or tools hold-alls. | zqwerty (97) | ||
| 609103 | 2007-11-09 10:06:00 | This has been a problem since the first ones came out, especially when the phones are banged around, ie young peoples phones, throwing them to each other, dropping them on the ground Well, all I can say is I've had cellphones since the first Motorola flips (which is well before most of the current crop of phone tossers were born) and none of them have ever had internal dirt problems. I've also worked in electronics for over 40 years and battery leakage and although fractured contacts were common with carbon-zinc and alkaline cells, soiling was not. Cellphone battery contacts were never an issue either, but mind you at the prices in those introductory days you didn't go throwing phones around. Battery life was a big problem though, especially with NiCads, and NiMH were not much better. The present crop of lithiums are excellent and the spring loaded contacts in the 2280 for example are strong enough to displace minor soiling. Not only that, contact soiling will not simulate low battery volts. If very severe (read hard encrusted deposits) it may cause the phone to appear to turn itself off intermittently, then come back on if the battery is taken out and reinserted, but Ohms Law and the conductivity of minor grubbiness are at odds with each other for anything more. I can't quite see how pseudo ball-sports could have an effect on contact cleanliness anyway, physical damage would be more likely, especially when dropping on the ground as you cite. Likewise the dirty contacts; they must be unbelievably grubby individuals to get that much soiling. I have an ancient 6230 that looks a wreck and a Sony Ericsson T100 that has lived longer and harder than any phone ought to, and shows it, but again they are pristine in the battery areas and the gold contacts are like new, as I would expect for gold plating. Maybe I live at the wrong end of town. :blush: Cheers Billy 8-{) |

| 609104 | 2007-11-09 15:17:00 | So you are not familiar with the TV remote that does not work until you open the compartment and spin the battery/batteries? Will then work reliably for a couple of weeks until the contact/s - terminal/s go high resistance again and need another clean/spin. The same thing happens with Cell Phones except you can't spin the battery pack you have to clean the contacts. | zqwerty (97) | ||

The same thing happens with Cell Phones except you can't spin the battery pack you have to clean the contacts. Yes I have done that too. Instructions in some cordless phones till you to wipe the contacts between the base unit and phone once in a while too, due to corrosive build up, so I well still stick to my statement in my previous post. :) |

I find that when that starts to happen, it's time to replace them, also, half the buttons on my remote die when the power gets low, which is also a good sign... last lot were rocket and were actually leaking when I threw them out :horrified in fact I have had several leaking ones in remotes recently, not just rocket brand |

| 609107 | 2007-11-12 00:39:00 | Although I am not saying that the following is the answer, I have to agree with Nigel. You must let ALL rechargable batteries (except lithium ion) go completely flat before recharging. I have a rechargable shaver and replaced the batteries after ten years. I was told that that was exceptional and was because I discharged the batteries completely before recharging. Most of those batteries only last for five years. If you do not want to be away from the charger when your phone goes flat, run it down at home. Call 0800 000000 which is a Telecom number that gives you menus that you can repeat over and over until the battery dies. It's not difficult and will extend the life of your battery and may stop any possible future problems. | Roscoe (6288) | ||
