Using your lithium stocks copyright mobile phone in G or Dual Mode drains the battery much quicker than just GSM mode. Somewhere in the manual for your phone will be listed the battery times separately for GSM and 3G. On modern mobile phones, the GSM only life-cycle can be up to 50% more efficient.
Nonetheless, the Volt is not something in GM's immediate plans. The idea for the Volt would require that a cost efficient 400-lb Lithium mines Ontario-ion battery be found. Lithium-ion batteries of this size are not currently available. Further advances in battery technology would be required to allow GM to consider making the Volt a production car. These are enhancements that could occur in as little as a year, or as many as 20 years. GM has stated that they feel the technology is almost there, yet a vehicle like this is probably about a decade away.
This model has a 8.9-inch touch screen display. It is a LED back-lit display and supports a variety of multi-touch gestures (which was a lot of fun to use!). The screen can be rotated 180 degrees to face outwards. Some of the other features includes a VGA port, 2 USB ports, audio jacks and a memory card reader. Instead of using the usual lithium-ion battery, this model is powered by a lithium-polymer battery.
When it's time to buy a new lithium ion battery, be sure you're buying one that's new (as in recently produced). Just like fruit has a shelf-life, so do batteries and just like you want to buy fresh produce, you also want to invest in "fresh" Lithium battery stocks ion cells. Check the date-code on the battery or packaging to ensure you're not buying a pack that's been degrading for a year on some shelf.
Memory effect will reduce the life of a battery. Modern Lithium-ion batteries do not suffer from memory effect, although it does occur in Nickel-Metal Hydride (NiMH) units when charged from levels other than 0% of battery capacity. If the (NiMH) unit was fully charged when initially at say 20% capacity, the resulting available capacity would only be 80% of the factory original. Of course every time you charged the battery, the total available capacity would reduce and eventually your mobile phone would prove to be increasingly useless. Nearly all new electronic devices are now powered by Lithium batteries. You should always condition your (NiMH) battery from new.
The odds that you will using the Lithium-Ion batteries are 99% ( that's if you are using the new breeds of laptops :) ). Just check the abbreviation that says LION or Li-Ion on your laptop battery label. There are still a few laptops that are using Ni-MH batteries these days and you might want to check with the manufacturer whether you can do an upgrade from Ni-MH to Li-Ion. Using unapproved batteries could led to dire consequences .... so do be very careful on this. If you have a higher budget you might want to check out SMART batteries. It has a power management circuitry and it will indicate to the user what is the current condition of the battery.
