Not being able to find a small internet radio to buy we liked, we got mobile
phone with which we link with wi-fi to a modem router, and use it as an internet radio. Keeping the phoned plugged into its charger all the time, we are using it to play *all-day* background classical music through an amplifier and speakers. Since the phone has no 'moving parts' unlike a computer, we are wondering if this continuous playing all day of the phone is going to shorten its working life ? |

Using anything shortens its working life. Not so. There aren't any obvious failure mechanisms in solid-state devices (other than dopant migration in high-power output transistors). It's also true that most mechanical devices "like" moderate use. Letting anything mechanical "sit" most of the time will probably cause it fail sooner than if receives regular use. It's now possible to build computers without moving parts (other than the optical drives). My new computer has a solid-state "hard disk", and you wouldn't believe how fast it boots up, or how fast programs start to run. |

With mechanical devices, regular moderate use provides a longer useful lifetime than using the device only rarely. Yes, this is also true with EM (Electro-Mechanical) devices like pinballs and jukeboxes (and other arcade games)- regular use keeps the contacts on the relays clean from their designed in rubbing action (overtravel). If the machine is not used then the contacts tend to oxidize and not pass electrical current well leading to service calls. HOWEVER the topic here is a solid state mobile phone - and that device really doesn't care too much if it is on or off as long as it operates in a reasonable temperature range (around 20 - 35C). Chances are it will be obsolete before it fails if it runs cool to the touch. Heat is the enemy of electronics, mostly capacitors - and their life gets quite short the warmer the operating temperature gets above 50C...just read the spec sheets. Typical electrolytics endurance: - up to 5,000 Hours at 105°C or about 210 days (7 months) running 24/7.

They contain "leveling" software that makes sure the disk is written to evenly. The Crucial disk I use is spec'd at about 40TB of total writes. |

You have to match the logic to the device. Light bulbs? Off makes them last longest. A car engine? You better exercise that sucker once in awhile if it sits outside fully fueled. Many electronic devices can tolerate 24/7 with few failures. Disk drives? Now that's a question. The early ones (sealed ones - not the very early ones where the platters were removable 12" disks) seemed to do better if they ran 'til they croaked. The early drum recorders seemed to last forever as long as they didn't stop running. (the heads rode on a wave of silicon oil and never touched the belts unless they stopped) |

I can vouch for the remark made but I can give you more details too: I use smartphones, tablets and laptops to listen to internet radio all the time and I've only had one device that suffered because of that. What happened to that particular device is the WiFi quit working and it doesn't even work after a factory reset. But out of all the other devices I've used they haven't demonstrated any problems at all. Rocky |

Yes, I've heard that and I've even seen one person that no longer has WiFi on their HP notebook but they claimed it was the switch itself that quit working so I try not to use the hardware WiFi switch on an HP notebook. Me, I've had a power plug fail on an HP ZD7000 notebook and that was common for that particular notebook. I've also had a DVD fail on an HP DV8000 notebook but when the second DVD failed too I went back to the first DVD and it has been working fine since then. I doubt if I'll ever figure that one out unless if it was a problem with the connector. Other than that, I've seen a lot of videos on youtube with problematic HPs where if it isn't the WiFi that goes out it is the video. Case in point: HP 's Worst Laptop Ever - Pavilion ZD8000 - http://www.youtube.com/watch?v=2stqQtQePcM&hd=1 Oddly enough I skipped getting the HP ZD8000 because I went from an HP ZD7000 to the HP DV8000 where the ZD8000 looks more like the ZD7000 than the DV8000. FYI the only device I had that lost the WiFi was a Pharos Traveler 137 that I got real cheap when a place was getting rid of them so I wasn't too upset when the WiFi quit on that. http://www.pharosgps.com/products/proddetail.asp?prod=001_PTL137_8.00 But the video on certain Dell Laptops? Don't get me started. Rocky |

So that means even though the WiFi quit working on the device mentioned above the bluetooth still seems to work OK so they must not be using the same transmitter or same receiver. http://www.mobileburn.com/definition.jsp?term=A2DP Rocky |

This might be where a Knoppix disk can help arbitrate between a software/configuration problem and a hardware failure. Any time I have something fail, I do the "Remove Device"/"Add Device" dance, then update drivers. If that fails, out comes the Knoppix disk. If it *still* fails, it's most likely hardware. I've been lucky so far and nothing has needed a lot of scrounging for Linux device drivers. -- Les Cargill |

wrote: My 39YO HP45 still works but the power switch is too flaky to be usable. I collect old HP LED type calculators. The HP 45 is well worth fixing and using. The switches tend to fail due to dirt accumulation and/or wearing a grove into the PCB contact area from overuse. I've repaired both problems. http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv018.cgi?read=131014 This is the dirt problem: http://i45.photobucket.com/albums/f96/geoff_q/gunk.jpg I couldn't find a photo of a grove worn in the contacts. I've been quite successful with just cleaning the switch area. I've also repaired missing gold problems with gold leaf. It was difficult, required a microscope, a steady hand, no air movement, and considerable patience. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |

Keeping the phoned plugged into its charger all the time, we are using it to play *all-day* background classical music through an amplifier and speakers. Several of my customers do exactly the same thing. Some play stored MP3/AAC music, while others stream from Pandora or Slacker. Most use an iPhone 3G, iPod Touch, or Droid A855 for the wi-fi connectivity. All have the phone plugged into a charger. No fatalities. Since the phone has no 'moving parts' unlike a computer, we are wondering if this continuous playing all day of the phone is going to shorten its working life ? It won't hurt the phone in any way. However, the internal battery is another story. For Li-Ion, battery life is shortened when the battery is hot, and when it's left at full charge all the time. For details, see: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries Most Li-ions are charged to 4.20V/cell and every reduction of 0.10V/cell is said to double cycle life. This is not much of a problem for easily replaceable inexpensive batteries, such as in the Droid A855, but might be an issue with the designed obsolescent iPhone series, where brain surgery is required to replace the battery. Apple has therefore wisely elected to charge their Li-Ion batteries to 4.1v or what I estimate to be 95% of full capacity. This greatly extends the battery life and will delay when you start cursing Apple products to about 3 years. http://stephenwmoore.wordpress.com/2009/07/21/iphone-battery-life/ Someone mentioned having a phone with a dead wi-fi. I have two Apple 3G iPhones, both with intermittent wi-fi sections. If I turn the power off on the iPhone for a day, the iPhones will have a working wi-fi section for about 30 minutes. I also have a third working iPhone 3G, where the wi-fi has never failed. I've been inside trying to repair them, and failed. -- Jeff Liebermann 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558 |
