Question about Sony Ericsson K850i Mobile Phone

Open Question

My mobile phone suddenly started to drain battery at an extremely fast rate (ca. 1h duration, instead of 8-10 days). Any hint on what could be wrong and how one could fix it? Thanks in advance!!!

1) The phone is > 6 years old 2) I got a new battery today, but same result, which means the problem comes from the phone. 3) The problem started right after I have been shooting a few pictures with flash on, though nothing I had not done before or unusual. 4) At the end of the charging phase, I get a message saying approximately " Serious failure - Stop using the phone and contact Sony Ericsson Customer centre". 5) The battery becomes really warm both during charging and while in use. This applies to both the olb battery and the new one I just installed.

My mobile battery is getting low very fast


It's probably old, and about time to change the battery. If not, could be some function that drains battery fast, eg. high accuracy location tracking. Set to battery saving option instead.

Last friday i bought the new HTC wildfire A3333 mobile nd put into charge for 8 hrs. The other day when i start to using one point of battery icon reduced nd on the same day i didnt nt use phone more. bt...


There could be 3 different things wrong:
1.) Battery is no good.
2.) Charger is no good.
3.) The port where you plug the charger into the phone is no good.

I would take it to your local mobile provider and ask them to test the phone, battery and charger. They will be able to tell you which one it is...battery and charger are pretty cheap fixes. If it is the port, you normally are better off getting a new phone.

I will drive for about a mile with full power with little power lose.then all of a sudden,ill have extreme power loss . within 1quarter mile ill lose all power.something drains the batteries


Batteries do not provide a linear output during usage, but having it die out within a mile or so tells me that one of the battery cells is becoming weaker than the rest. If you're a handyman, you can save yourself a ton of money by replacing only the batteries (try interstate batteries) instead of going to the scooter store and purchasing the batteries and case.

Hi, my ultimate 9502 phone battery is dead withing less than one hour. how do i fix this problem. how do i make sure is this problem on battery or phone? please advice me


One setting that will drain your battery extremely fast is having the GPS set to "Always-On," or "Location-On." Instead, try setting it to "E911" or "Emergency only." This stops constantly transmitting your exact location unless you dial 911.

LG Viewty battery discharges quickly .....


Charging duration does not connect to battery lasting duration in any way.Optimal charging time is 3 to 4 hours.your battery will drain soon if you keep your touchscreen pressed continuously in your jeans pocket.Keep bluetooth switched off. Reduce the brightness of your mobile display. Play music threw headphone rather than using loudspeakers.
