Motorola FIRE XT Tips for extending battery life
Back to Previous Page

Are there any tips on how to extend the battery life?
Things you should know about charging your battery.

New batteries are not fully charged. Plug the battery charger into your phone and an electrical outlet. Your phone might take several seconds to start charging the battery.
  • It may take several charging cycles for your battery to reach optimum performance.
  • The battery charger shipped with this device is designed specifically for Motorola mobile phones. Other chargers might take longer to charge your battery, or cause your calls to fail during charging.
  • You can charge your phone via USB cable but this charging time will vary based on computer specifications.
Tips to extend battery life:
  • Select a shorter backlight duration
  • Lower the display brightness
  • Use the AC adapter to charge your phone whenever possible
  • Turn Bluetooth off when not in use
  • Turn Wi-Fi off when not in use
  • Close any third party applications running in the background
  • Playing music, videos and viewing images in your phone will affect your battery life
General Battery use & safety
  • Motorola recommends you always use Motorola-branded batteries and chargers. The warranty does not cover damage caused by non-Motorola batteries and/or chargers.

    Caution: Use of an unqualified battery or charger may present a risk of fire, explosion, leakage, or other hazard. Improper battery use, or use of a damaged battery, may result in a fire, explosion, or other hazard.
  • Your battery can be charged without it being fully depleted, and can be charged every day if desired.
  • Battery usage by children should be supervised.
  • Important: Motorola mobile devices are designed to work best with qualified batteries. If you see a message on your display such as Invalid Battery, Invalid Charger or Unable to Charge, take the following steps:
    • Remove the battery and inspect it to confirm that it bears a Motorola "Original Equipment" hologram;
    • If there is no hologram, the battery is not a qualified battery
    • If there is a hologram, replace the battery and retry charging it
    • If the message remains, contact a Motorola Authorized Service Center
  • New batteries or batteries stored for a long time may take more time to charge.
  • Charging precautions: When charging your battery, keep it near room temperature. Never expose batteries to temperatures below 0°C (32°F) or above 45°C (113°F) when charging. Always take your mobile device with you when you leave your vehicle
  • When storing your battery, keep it in a cool, dry place.
  • It is normal over time for battery life to decrease, and for the battery to exhibit shorter runtime between charges or require more frequent or longer charging times. Motorola batteries are designed to last between 350-700 charge/discharge cycles at room temperature. This amounts to approximately a year to a year and a half of battery use for most people.
  • Avoid damage to battery and mobile device. Do not disassemble, open, crush, bend, deform, puncture, shred, or submerge the battery or mobile device. Avoid dropping the battery or mobile device, especially on a hard surface. If your battery or mobile device has been subjected to such damage, take it to a local service center before using. Do not attempt to dry it with an appliance or heat source, such as a hair dryer or microwave oven.
  • Use care when handling a charged battery-particularly when placing it inside a pocket, purse, or other container with metal objects. Contact with metal objects (such as jewelry, keys, beaded chains) could complete an electrical circuit (short circuit), causing the battery to become very hot, which could cause damage or injury.

Why does my Nokia phone say "charger not supported?

That error message usually occurs when using an unsupported third party charger. An example would be if you bought a cheap "knock off" charger that doesn't supply the correct voltage to the phone. These messages can sometimes occur in error when using an official or supported charger.
If you're sure you're using a supported charger, there is something you can try to fix this error. First, unplug the charger from the phone and the power outlet. Turn off the phone and then remove the battery. Wait about 15 seconds and insert the battery again. Turn on the phone, and plug in the charger to the power outlet and the phone. The phone should now charge.
If it's still not working, you'll need to try to get a new charger. Sometimes, if the phone is still in warranty, you can get the charger replaced for free if it is defective.

Dear Sirs, I'm using Sony Ericsson K800i cell phone. As soon as I put the phone into charger it displays:"Charging Error. Stop Charging!" I thought it may be battery problem and bought new...

If you have bought new battery, and still not working. You can consider that the faulty is in the charger adapter. You can bring your phone to a service center to further check the charger and/or the circuitry of your unit.
