Hello

Your system definitely uses a lithium ion battery.

Over their lifespans, lithium-ion batteries can lose the ability to hold a charge. After a few years, some batteries will last only a fraction of the rated runtime. Replacing a battery is relatively simple; most pop out from the bottom or back of the laptop.

Many retailers, however, charge hundreds of dollars for a new battery. Sites like batteries.com specialize in discount laptop batteries and can save you money on a brand new battery for your laptop. For example, a Dell Latitude D620 Li-ion battery costs $139 on Dell's Web site and $83.99 on batteries.com, as of press time. (The company even offers a two-year warranty and 45-day money-back guarantee on all laptop-battery orders.)

the battery charger is maybe defective already you can purchase new charger from dealer

If the troubleshooting section in the back of the user guide doesn't help, I sugget getting in touch with Sony and asking them if it's normal, the only thing I can suggest in the meantime, is taking the battery out while it's not in use, or recharge it a few hours before you're due to use it. Phones get like it after a few years and with technology advancing the way it is these days, you'd expect a battery life lasting longer than a week, not a day.

Things to consider:
1. When it's off, is it off or left on standby?
2. Where did you buy both the camera and batteries from?
3. When you charge it up, do you charge it up with a half charged battery or a totally dead battery?

hi sir... dont change ur batteries or go for new one... Its becuase the battery pin available in ur mobile device has got damaged... so its unable to store charges for a longer duration...Better give ur mobile for service and they will replace u with new pins.. dont waste in getting new batteries..

thank u rate me!!!

Remember it's always important to take care of your device.. especially a mid-level device like the K550i. Sony Ericcson prides themselves in edgy techno-savvy devices but leave little room for accommodating ruggedness--they are delicate. You may be able to go to your wireless carrier and exchange or utilize a battery until your device arrives. If you have an older device you can put your SIM card in there and use that also until the old phone comes. There are self-charge batteries but they dont last days and you will have continually buy another one when the previous one dies. They only last 2-4 hours and can be purchased in the Wal-Mart electronics section. You have to make sure they make one for your model device. I hope this information helps you and good luck!! Rule of thumb: Always buy an extra battery! Have a great holiday!

Go to sony ericsson website and search for battery genuineness checking page. Provide your battery serial no. and check whether its original battery or not. If its fake, then approach the dealer from whom you bought this mobile.

This camera has had problems with the primary switch block faulting. The camera will power up all by itself when unattended and drain the battery. Another symptom would be the battery refuses to charge fully because the camera must remain in the "OFF" mode for the charge process to begin. Sony in Laredo, TX is replacing these controls at little or no cost, I would call them to see if they will repair this for you. Hope this helps you.

You have either a faulty charger, a faulty battery or a fault in your camera. I purchased 2 batteries for my Sony 505v and from new one of them kept flashing an empty battery sign right in the middle of the display. Actually it was fully charged but Sony batteries have a little circuit inside them which tell you how long the batteries will last. In my case I could continue to use the battery but put up with that flashing icon. I returned it to where I purchased it and it was replaced Immediately. Please ,next time give us a little more information as to what battery type it is and which camera it goes in. Some cameras can develop a natural short circuit over time. BMW
