Too low standby?
The indicated standby time is a maximum value under optimum conditions. However, in practice the standby time can be significantly affected by the network configuration, SIM card configuration, reception conditions and equipment settings.
Various combinations of the above factors means that standby time may vary considerably.
The actual transmission power depends on the distance to the transmitter (distance). If the phone is using lots of power to transmit over a considerable time period, i.e. is a long way from the transmitter or reception conditions are difficult (e.g. in buildings, underground garages, areas with poor coverage, etc.), shorter standby times are to be expected.
Several network parameters also affect standby time. One parameter, for example, stipulates how often the mobile telephone has to register with the network (location update). Each cycle increases the power consumption significantly and consequently decreases the standby time.
In addition, each time the equipment is used, e.g. for telephoning, activating the display backlight, operating the menu, SMS messaging etc., energy is used and consequently the standby times become shorter.
If the infrared interface is activated, more power may be consumed if it "detects" an active infrared source, e.g. infrared ports on PCs or a television control, the handy regularly registers with this interface. This too increases power consumption.
Measured value in standby mode:
-> 1 minute of telephoning reduces the standby time by/to 2 hours, depending on the transmission power
-> 1 minute of activated display reduces the standby time by 1 hour
-> 10 seconds of playing within the menu reduces the standby time by 10 minutes
-> 1 minute of searching the network reduces the standby time by 1/4 hour
-> 1 minute of cell broadcasts (continuous) reduces the standby time by 1/2 hour
-> Screensaver, animations and background pictures can reduce the standby time by up to 50%!

How to charge new battery? / I plug the charger but nothing is show!!!
Battery cutout/deep discharge
In general, any battery can undergo deep discharge.
-> Once deep discharge occurs, the phone will not switch on.
-> When the charger is connected, the charging symbol will not show in the display.
Batteries in deep discharge need to be charged in the following way:
Series 75 / 65 / C62 / 60 / 55 / 57:
The mobile phone has to be connected to the delivered charger. After 15-20 minutes the charging symbol will appear in the display again. The battery must be loaded further until the charging symbol disappears or until it shows "full" (after approx. 2 hours). The battery will then change automatically to the normal charging mode. The charger does not need to be unplugged during this procedure.
ST55 / ST60:
In case of deeply discharged battery, the voltage of the battery is too low to operate the charging curcuit and the display controller, the phone cannot be turned on and the normal charging process cannot be started. No charging symbol is visible in the display for more than 4,5 (!) hours.
In this case charging the battery is divided into two different steps which have to be run subsequently:
1-> Trickle charge:
Trickle charge mode is automatically started if the battery voltage is below 3.0V when the charger is connected to the mobile. The charging symbol will not be shown in the display.
2-> Normal charge:
When the battery voltage is above 3.0V the mobile will start the normal charging mode and the charging symbol is shown in the display. Always charge a new battery or a deep discharged battery for more then 16 (!) hours before first use !
Please make sure the triangle on the charger connector mark faces down.
S40:
After inserting the battery the device is not ready to use. Connect the new device to a charger for at least 2 hours!
-> Important: Nothing will show in the display at first. The battery will change automatically to the normal charging mode within 60 minutes.
-> The batteries are not charged on delievery!
-> Carry out this procedure when battery is in deep discharge.
CL 50 : Deep Discharge Battery:

For many years, nickel-cadmium was the only suitable battery for portable applications from wireless communications to mobile computing. In 1990, the nickel-metal-hydride and lithium-ion emerged, offering higher capacities. Both chemistries fought nose to nose, each claiming better performance and smaller sizes. Today, lithium-ion has won the limelight and has become the most talked-about battery. It's the fastest growing and most promising battery chemistry of today.
The lithium-ion battery
Pioneer work with the lithium battery began in 1912 under G.N. Lewis but it was not until the early 1970s when the first non-rechargeable lithium batteries became commercially available. lithium is the lightest of all metals, has the greatest electrochemical potential and provides the largest energy density for weight.
Attempts to develop rechargeable lithium batteries failed due to safety problems. Because of the inherent instability of lithium metal, especially during charging, research shifted to a non-metallic lithium battery using lithium ions. Although slightly lower in energy density than lithium metal, lithium-ion is safe, provided certain precautions are met when charging and discharging. In 1991, the Sony Corporation commercialized the first lithium-ion battery. Other manufacturers followed suit.
The energy density of lithium-ion is typically twice that of the standard nickel-cadmium. There is potential for higher energy densities. The load characteristics are reasonably good and behave similarly to nickel-cadmium in terms of discharge. The high cell voltage of 3.6 volts allows battery pack designs with only one cell. Most of today's mobile phones run on a single cell. A nickel-based pack would require three 1.2-volt cells connected in series.
Lithium-ion is a low maintenance battery, an advantage that most other chemistries cannot claim. There is no memory and no scheduled cycling is required to prolong the battery's life. In addition, the self-discharge is less than half compared to nickel-cadmium, making lithium-ion well suited for modern fuel gauge applications. lithium-ion cells cause little harm when disposed.
Despite its overall advantages, lithium-ion has its drawbacks. It is fragile and requires a protection circuit to maintain safe operation. Built into each pack, the protection circuit limits the peak voltage of each cell during charge and prevents the cell voltage from dropping too low on discharge. In addition, the cell temperature is monitored to prevent temperature extremes. The maximum charge and discharge current is limited to between 1C and 2C. With these precautions in place, the possibility of metallic lithium plating occurring due to overcharge is virtually eliminated.
Aging is a concern with most lithium-ion batteries and many manufacturers remain silent about this issue. Some capacity deterioration is noticeable after one year, whether the battery is in use or not. The battery frequently fails after two or three years. It should be noted that other chemistries also have age-related degenerative effects. This is especially true for nickel-metal-hydride if exposed to high ambient temperatures.
Manufacturers are constantly improving lithium-ion. New and enhanced chemical combinations are introduced every six months or so. With such rapid progress, it is difficult to assess how well the revised battery will age.
Storage in a cool place slows the aging process of lithium-ion (and other chemistries). Manufacturers recommend storage temperatures of 15°C (59°F). In addition, the battery should be partially charged during storage. The manufacturer recommends a 40% charge.
The most economical lithium-ion battery in terms of cost-to-energy ratio is the cylindrical 18650 (18 is the diameter and 650 the length in mm). This cell is used for mobile computing and other applications that do not demand ultra-thin geometry. If a slim pack is required, the prismatic lithium-ion cell is the best choice. These cells come at a higher cost in terms of stored energy.
Advantages
* High energy density - potential for yet higher capacities.
* Does not need prolonged priming when new. One regular charge is all that's needed
* Relatively low self-discharge - self-discharge is less than half that of nickel-based batteries.
* Low Maintenance - no periodic discharge is needed; there is no memory
Limitations
* Requires protection circuit to maintain voltage and current within safe limits.
* Subject to aging, even if not in use - storing the battery in a cool place and at 40% charge reduces the aging effect.
* Moderate discharge current - not suitable for heavy loads.
* Transportation restrictions - shipment of larger quantities may be subject to regulatory control. This restriction does not apply to personal carry-on batteries.
* Expensive to manufacture - about 40 percent higher in cost than nickel-cadmium.
* Not fully mature - metals and chemicals are changing on a continuing basis.
The lithium Polymer battery
The lithium-polymer differentiates itself from conventional battery systems in the type of electrolyte used. The original design, dating back to the 1970s, uses a dry solid polymer electrolyte. This electrolyte resembles a plastic-like film that does not conduct electricity but allows ions exchange (electrically charged atoms or groups of atoms). The polymer electrolyte replaces the traditional porous separator, which is soaked with electrolyte.
The dry polymer design offers simplifications with respect to fabrication, ruggedness, safety and thin-profile geometry. With a cell thickness measuring as little as one millimeter (0.039 inches), equipment designers are left to their own imagination in terms of form, shape and size.
Unfortunately, the dry lithium-polymer suffers from poor conductivity. The internal resistance is too high and cannot deliver the current bursts needed to power modern communication devices and spin up the hard drives of mobile computing equipment. Heating the cell to 60°C (140°F) and higher increases the conductivity, a requirement that is unsuitable for portable applications.
To compromise, some gelled electrolyte has been added. Most of the commercial lithium-polymer batteries used today for mobile phones are a hybrid cells and contain gelled electrolyte. The correct term for this system is lithium-ion-polymer. This is the only functioning polymer battery for portable use today.
With gelled electrolyte added, what then is the difference between classic lithium-ion and lithium-ion-polymer? Although the characteristics and performance of the two systems are similar, the lithium-ion-polymer is unique in that solid electrolyte replaces the porous separator. The gelled electrolyte is simply added to enhance ion conductivity.
Lithium-ion-polymer has not caught on as quickly as some analysts had expected. Its superiority to other systems and low manufacturing costs has not been realized. No improvements in capacity gains are achieved - in fact, the capacity is slightly less than that of the standard lithium-ion battery. lithium-ion-polymer finds its market niche in wafer-thin geometries, such as batteries for credit cards and other such applications.
Advantages
* Very low profile - batteries resembling the profile of a credit card are feasible.
* Flexible form factor - manufacturers are not bound by standard cell formats. With high volume, any reasonable size can be produced economically.
* Lightweight - gelled electrolytes enable simplified packaging by eliminating the metal shell.
* Improved safety - more resistant to overcharge; less chance for electrolyte leakage.
Limitations
* Lower energy density and decreased cycle count compared to lithium-ion.
* Expensive to manufacture.
* No standard sizes. Most cells are produced for high volume consumer markets.
* Higher cost-to-energy ratio than lithium-ion
