To optimize the lifespan of the batteries
When to reload the batteries? Should a complete discharge be awaited? Does a complete discharge have for effect "to restore", or "to repair", a battery which would lose in autonomy?
The answers to these frequent questions depend on the type of battery considered.
- various batteries and accumulators
Let us retain three families of batteries:
- Nor-Cd (Nickel and Cadmium);
- Nor-Mh (Nickel and Metal-Hydride);
- the Lithium-Ion and Lithium-Polymer.
The three are not subjected to the same rules of use and maintenance. The batteries with lithium have one lifespan (often) more reduced but are of a less constraining maintenance. Nor-Cd are most complex to maintain, but propose the longest lifespan (a number of complete cycles), with the proviso of respecting the constraints of use, while Nor-Mh an interval proposes.
- Of the two "ratchet effects"
The batteries Nor-Cd and Nor-Mh are, both, subjected so that one calls, in the majority of the situations wrongly, the ratchet effect. There exists, indeed, two ratchet effects.
The first case, extremely rare, is that in which a battery ' souvient' of the moment (level of load) to which the user is proceeded systematically to a refill. Thus, ' habituée' with being reloaded on this very precise level, the battery can refuse to function beyond: it memorized a threshold. It is a phenomenon far from frequent, with which researchers of NASA were confronted. The commun run of the users will never manage to reload systematically its battery Nor-Cd or Nor-Mh on the same level of discharge, and this with sufficiently of precision to be confronted with this situation.
The second ratchet effect, sometimes qualified "false ratchet effect", is most current. The "false ratchet effect" is defined as "the crystalline material formation causing [ one ] loss of capacity". In other words, it acts of a chemical phenomenon, caused by electric overloads, which involves an apparent loss of endurance of the battery concerned. To avoid it, it is advisable never not to leave a battery in overload and to proceed, punctually (but not systematically) with complete discharges of the battery (see low).
It is important to note that the batteries Nor-Mh are exposed to the ratchet effect as well as Nor-Cd: most recent Nor-Mh had like commercial argument not to be exposed to this nuisance. Actually, the phenomenon is less sensitive for Nor-Mh for a simple reason: they have one lifespan, by nature, shorter, so that the effect of memory appears at the end of ' the life naturelle'.
The batteries Nor-Cd and Nor-Mh, very widespread, must thus be the subject of precise rules of use (which are worth more for Nor-Cd, therefore).
- maintenance of the batteries Nor-Cd and Nor-Mh: myths and realities
It is an extremely widespread commonplace: the idea according to which it is necessary to await a complete discharge of the batteries Nor-Mh or Nor-Cd before proceeding to a refill... This idea is largely false: it is rather advisable to carry out complete discharges in a specific way, but not systematically. Canadian professionals observed that the complete and systematic discharges had harmful effects resulting in a loss of endurance.
If it is not imperative systematically to carry out a complete discharge of the batteries, it can sometimes be necessary to operate major discharges in a specific way, making it possible to fight against the "false ratchet effect", by reversing the chemical reaction described above. It is thus possible "to restore" a battery victim of crystallization... But this method supposes to have an ad hoc material. Why can't one use the electronic instrument profiting from the batteries to discharge these last? For a simple reason...
The majority of the electronic instruments stop functioning since the batteries do not provide any more the good power. However it is exactly what occurs with a battery victim of the false ratchet effect: the crystallized part does not make it possible to obtain a voltage as important as the intact part. There is thus a fall of tension. Indeed, if the battery could provide 1,2v when it was intact, as soon as it will reach the threshold from which nickel ' cristallisé' enters in action, the current is lower (for example with 1,02v). The electronic instrument will immediately cease functioning, giving the illusion that the battery lost in capacity; actually, the battery is able always to function. Many users replace the battery in load then, longer than usually: the phenomenon of crystallization worsens, and the battery is less and less powerful.
The solution then consists in discharging the battery completely... But that cannot be done with the electronic instrument, since this one stops functioning since the battery does not deliver sufficiently any more of electric tension. It is, so imperative to use an electronic equipment of discharge and to strictly control this discharge: one speaks then about major discharge.
- the tidal wave Lithium-Ion and Lithium-Ion-Polymer
Since a few tens of month, the batteries Lithium-Ion, before used almost exclusively on the portable computers, made their appearance on electronic instruments of very reduced format: Mobile PDA and telephones in particular. The iPod also has a battery Lion-Ion-Polymer.
These batteries have the advantage of not being subjected to "the ratchet effect" of the fact, in particular, of the best held of lithium vis-a-vis with the problem of crystallization; the user is thus freed from the traditional rules: it is indeed useless (even bad) to carry out periodic major discharges. However, the overloads, if they are theoretically less dangerous, are to be avoided. In fact, it is preferable to proceed to short daily loads of a few minutes, and this so as to reduce the number of complete cycles of refill.
Let us conclude on wisdom from the Support service from Handspring: "to frequently proceed to partial loads the optimal effectiveness of any aircraft equipped with a battery lithium-ion ensures."
That it is said!

Optimiser la durée de vie des batteries
Quand recharger les batteries ? Faut-il attendre une décharge complète ? Une décharge complète a-t-elle pour effet de "restaurer", ou "réparer", une batterie qui perdrait en autonomie ?
Les réponses à ces questions fréquentes dépendent du type de batterie considéré.
- Des différentes batteries et accus
Retenons trois familles de batteries :
- les Ni-Cd (Nickel et Cadmium) ;
- les Ni-Mh (Nickel et Metal-Hydrure) ;
- les Lithium-Ion et Lithium-Polymère.
Les trois ne sont pas soumises aux mêmes règles d’usage et d’entretien. Les batteries au lithium ont une durée de vie (souvent) plus réduite mais sont d’un entretien moins contraignant. Les Ni-Cd sont les plus complexes à entretenir, mais proposent la durée de vie la plus longue (nombre de cycles complets), à condition de respecter les contraintes d’usage, tandis que les Ni-Mh proposent un entre-deux.
- Des deux "effets mémoire"
Les batteries Ni-Cd et Ni-Mh sont, toutes deux, soumises à ce que l’on appelle, dans la plupart des situations abusivement, l’effet mémoire. Il existe, en effet, deux effets mémoire.
Le premier cas, extrêmement rare, est celui dans lequel une batterie se ’souvient’ du moment (niveau de charge) auquel l’utilisateur procède systématiquement à une recharge. Ainsi, ’habituée’ à être rechargée à ce niveau très précis, la batterie peut refuser de fonctionner au-delà : elle a mémorisé un seuil. Il s’agit là d’un phénomène très peu fréquent, auquel ont été confrontés des chercheurs de la NASA. Le commun des utilisateurs ne parviendra jamais à recharger systématiquement sa batterie Ni-Cd ou Ni-Mh au même niveau de décharge, et ce avec suffisamment de précision pour être confronté à cette situation.
Le second effet mémoire, parfois qualifié de "faux effet mémoire", est le plus courant. Le "faux effet mémoire" se définit comme "la formation de matériau cristallin occasionnant [une] perte de capacité". En d’autres termes, il s’agit d’un phénomène chimique, provoqué par des surcharges électriques, qui entraîne une perte apparente d’endurance de la batterie concernée. Pour l’éviter, il convient de ne jamais laisser une batterie en surcharge et de procéder, ponctuellement (mais pas systématiquement) à des décharges complètes de la batterie (voir plus bas).
Il est important de noter que les batteries Ni-Mh sont exposées à l’effet mémoire au même titre que les Ni-Cd : les plus récentes Ni-Mh avaient comme argument commercial de ne pas être exposées à ce désagrément. En réalité, le phénomène est moins sensible pour les Ni-Mh pour une raison simple : elles ont une durée de vie, par nature, plus courte, si bien que l’effet de mémoire apparaît en fin de ’vie naturelle’.
Les batteries Ni-Cd et Ni-Mh, très répandues, doivent donc faire l’objet de règles d’usage précises (qui valent plus pour les Ni-Cd, donc).
- L’entretien des batteries Ni-Cd et Ni-Mh : mythes et réalités
Il est un lieu commun fort répandu : l’idée selon laquelle il faut attendre une décharge complète des batteries Ni-Mh ou Ni-Cd avant de procéder à une recharge... Cette idée est largement fausse : il convient plutôt de procéder à des décharges complètes de façon ponctuelle, mais pas systématiquement. Des professionnels Canadiens ont observé que les décharges complètes et systématiques avaient des effets nocifs se traduisant par une perte d’endurance.
S’il n’est pas impératif de procéder systématiquement à une décharge complète des batteries, il peut parfois être nécessaire d’opérer des décharges profondes de façon ponctuelle, permettant de lutter contre le "faux effet mémoire", en inversant la réaction chimique décrite plus haut. Il est ainsi possible de "restaurer" une batterie victime de la cristallisation... Mais cette méthode suppose d’avoir un matériel ad hoc. Pourquoi ne peut-on pas utiliser l’appareil électronique bénéficiant des batteries pour décharger ces dernières ? Pour une raison simple...
La plupart des appareils électroniques s’arrêtent de fonctionner dès lors que les batteries ne fournissent plus la bonne tension. Or c’est exactement ce qui se produit avec une batterie victime du faux effet mémoire : la partie cristallisée ne permet pas d’obtenir un voltage aussi important que la partie intacte. Il y a donc une baisse de tension. En effet, si la batterie pouvait fournir 1,2v lorsqu’elle était intacte, dès qu’elle va atteindre le seuil à partir duquel le nickel ’cristallisé’ entre en action, le courant sera inférieur (par exemple à 1,02v). L’appareil électronique cessera immédiatement de fonctionner, donnant l’illusion que la batterie a perdu en capacité ; en réalité, la batterie est toujours en mesure de fonctionner. Beaucoup d’utilisateurs replacent alors la batterie en charge, plus longtemps que d’ordinaire : le phénomène de cristallisation s’aggrave, et la batterie est de moins en moins performante.
La solution consiste alors à décharger complètement la batterie... Mais cela ne peut pas être fait avec l’appareil électronique, puisque celui-ci s’arrête de fonctionner dès lors que la batterie ne délivre plus suffisamment de tension électrique. Il est, de ce fait, impératif d’utiliser un matériel électronique de décharge et de contrôler strictement cette décharge : on parle alors de décharge profonde.
- Le raz-de-marée Lithium-Ion et Lithium-Ion-Polymère
Depuis quelques dizaines de mois, les batteries Lithium-Ion, auparavant utilisées presque exclusivement sur les ordinateurs portables, ont fait leur apparition sur des appareils électroniques de format très réduit : PDA et téléphones mobiles en particulier. Le iPod dispose également d’une batterie Lion-Ion-Polymère.
Ces batteries ont l’avantage de ne pas être soumises à "l’effet mémoire" du fait, notamment, d’une meilleure tenue du lithium face au problème de la cristallisation ; l’utilisateur est ainsi affranchi des règles classiques : il est en effet inutile (voire mauvais) de procéder à des décharges profondes périodiques. Cependant, les surcharges, si elles sont théoriquement moins dangereuses, sont à éviter. De fait, il est préférable de procéder à de courtes charges quotidiennes de quelques minutes, et ce de manière à réduire le nombre de cycles complets de recharge.
Concluons sur la sagesse du service Support d’Handspring : "procéder fréquemment à des charges partielles assure l’efficacité optimale de tout appareil équipé d’une batterie lithium-ion."
Qu’on se le dise !

I wan´t Msn contacts with my phone contacts mixing.. I hope anyone can understand my bad english and try help me. Thanks a lot for all good works you made every day.
you could maybe add the msn contacts to a separate category.
with the very nice PocketInformant contact application replacement, you can than very easily filter that category out so you wan't see those contacts anymore. just an idea, didn't try it yet.
trata de usar pocketcm, este programa pa tus contactos solamente te da los contactos q tienen un numero movil, o si no trata octro talk e cmo msn pro no te syncronisa too tus contactos
chaos
@tomazez: Please translate your post. And if can't, could somebody else do it?
Muchas Gracias por tu respuesta. I Will try both solutions and then tell you whats up.
Many of my contacts are old or from work and I want see it in my personal cel....
gracias nuevamente.
.... espero impaciente la TNT 5, estoy usando la 4 y anda muy bien.
.... Waiting fot TNt 5.0 !.
Saludos, gracias y quedo a disp de cualquiera que pudea serle util...

have downloaded and tried pocket informant, it is a nice piece of software but it leaves a huge memory footprint(almost 4 mb) and it is entirely too complex for what most people are looking for. I personally prefer pocketCM but then again I cant really filter my contacts either.
I´m really very contented and I´m been thankful by its answers. Tonight I am going to try to prove them, but it must exist a root solution.
To always use a filter in a data base is like a "patch".
… you are extraordinary people, this is one of better forums than I know!

how can you make this?
I need it for a helmet headset from Cardo Scala Rider to use with the p3600 with ROM Fly, wm6
HELP ME PLEASE
Thank you
hello,
I have the same probleme and I find the solution.
1) use regedit and go tohklm/software/oem/voice command.
2)change the value lauchapenable from 1 to 0
3 change Voicecmdduration with 86400 (this is provide 24 hours recording).
Voice command still working, but not with the bluetoth eadset.
Normaly it's work for music, tomtom.....

Anche io ho risolto il problema
I have resolve the problem whit this post
Hi, this is a solution, but in this way i'm not able to use cyberon voice.
There was a good utility (btaudiotoggle) that allow you to turn on/off the redirection of all system audio audio to your Bluetooth Headset, but it's not working with p3600.
Is it possible to use it?
I have a Dainese bluetooth helm and have the same problem.
I tried several tools.
With a demo version of bluemusic, http://www.teksoftbluemusic.com/ I can transfer all audio to the bluetooth headset/helm (aftres pressing the pickup button once) But Voice dialing is not working anymore then.
I would like a solution where audio is transferred to the headset and where I can still use the voice dialing with the headset.

Easiest way to prevent this: Set security to WPA2, and use a strong passkey that is a combination of uppercase, lowercase, numbers, and special characters. You can substitute these in a word, for example: [email protected]$k3y! or [email protected]$Sw0rD&
Once you do this, no one will be able to connect to your hotspot without the passkey.

Una volta fatto ciò, nessuno sarà in grado di connettersi al tuo hotspot senza la passkey.

CHi, thank you for replying. Unfortunately they are already precautions that I have taken and I don't understand how this person manages to steal my connection anyway. I have entered complex and meaningless network passwords, just to understand if it is the password (among other things changed by me about three times a day!) to be discovered or if there is some capable program to decipher even the hieroglyphs. I set wpa2 security .. I have no hope

That simply is not possible. If you set the passkey to something that only YOU know, then there is no way for someone else to connect to your hotspot.
What makes you think this is happening? Can you provide a screenshot?
What device do you have?

Questo semplicemente non è possibile. Se imposti la passkey su qualcosa che solo TU conosci, non c'è modo per qualcun altro di connettersi al tuo hotspot.

H un Cubot note 20 pro The manufacturer finally got back to me and told me that there is no way in this smartphone to take any extra precautions. In fact, I'm using the connection with an ethernet cable, at least until I will not change, hopefully soon, device.I'm really upset because the phone otherwise works well and looks good Thanks bye
