On MobilePro systems, which both batteries have fully discharged, the user must perform a hard reset after charging the batteries for approximately 10 hours to ensure proper operation. If the systems fails to power on the user must perform a "hard" reset to initialize the power management circuitry.

Ku990 battery discharging


the magnetic closer may be causing interference with the units ability to stay connected to service..if thats the issue it will constantly be searching for a signal which sucks power to do..like being in a metal enclosure and getting reduced bars..

Hey


It sounds like you will need to take the phone in for professional servicing or possibly replacement. Here are a few suggestions to try before doing that. First, read the manual for proper battery maintenance and follow it strictly. Allow the battery to fully discharge, then fully recharge it (but do not overcharge it) then run it all the way down. Then repeat that process. This is called "resetting the battery".
Second, You may try replacing the battery (it is always good to have a second one for the Q anyway).
If all else fails, try a master reset. The Q is vulnerable to certain viruses just like any other computer. Caution: Completing a Master Reset will cause you to lose all of your personal information and additions to your phone. You can complete a master reset by clicking on Start, then System Tools, then click on the "Master Reset" icon.

Battery fast discharge


Battery is probably at the end of its life or then there is a problem with the motherboard causeing it to consume greater amounts of power, only solution to that would be to replace the motherboard.

try with a difrent battery?

"Fatal Application Error"


This problem may occur if the user allows the batteries to discharge to a state where the MobilePro must shut itself down. This state may cause the system storage memory to become unstable requiring a "hard" reset after the system has been fully charged again. Failure to perform the hard reset may result in data loss at a later time. The user manual states that if you receive a message indicating that the batteries are low, immediately connect the AC adapter to the device. The solution is to perform a "hard" reset after fully charging the internal batteries, and then install the service packs, software updates and user software.

Fully charge the Mobilepro battery


No. Lithium Ion batteries prefer a partial rather than a full discharge. Repeated full discharging robs the battery of its capacity (useful life), the Lithium Ion battery prefers shallow over repetitive deep discharge cycles. Besides cycling, the performance of the Li-ion is also affected by aging. Capacity loss through aging is independent of use however the capacity is affected by both aging and usage. Battery wear-down on lithium-based batteries is caused by two activities: actual usage or cycling and aging. The wear-down affects by usage and aging apply to all batteries but this is more pronounced on lithium-based systems. The Li-ion batteries prefer a shallow discharge. Partial discharges produce less wear than a full discharge and the capacity loss per cycle is reduced. Simple Guidelines to extend useful life of the battery Charge the Li-ion often, except before a long storage. Avoid repeated deep discharges. Keep the Li-ion battery cool. Prevent storage in a hot car. Never freeze a battery.
