Question about Samsung SCH-u340 Cellular Phone

4 Answers

Battery/charge When I bought my samsung sch u340 I plugged it in for the first initial charge, charged it to full. And now it won't keep a charge more than 1 day. Is the battery under warranty. Can I get a new one?

    My phone suddenly started posting a message saying "non user supported battery see user manual". What do I do to fix it?

    I have the same problem. Some days I'll have 3 or 4 bars at the end of the day if I've used the phone, other days, I have 1 bar at the end of 8 hours without having touched it. This battery is supposed to have 220 hours standby time. I also have had the problem of the phone dropping my alarm clock which is set to go off M-F.

OK, I tried something that this solution made me think of. I put a little shim made from a piece of folded paper to make the battery fit tighter against the contacts. The phone started right up! I put the shim opposite the contacts. Not 100% sure yet but I'd figured I'd post this. Good luck.

I just had the same problem. I took out my battery and noticed its copper contact points were corroding slightly with a blue-green powder residue. I wiped down the battery, took a cotton swab with a dab of hydrogen peroxide, cleaned the corrorsion off the copper contact points, and voila! It works again! It has been very humid lately, and I wonder if the moisture contributed to the problem because my phone has never been wet, yet the battery compartment had a tiny bit of liquid in it. Condensation? Who knows.

what you need to do is take the phone to a mobile tech or a mobile service center and have them service the phone, have them give the phone a full service and that will correct the problem and also do a eprom reset.
