Samsung Focus not charging

 

Today I run into a hardware bug with my Samsung Focus – no matter how long I’d keep the phone plugged in, it showed the same battery level, somewhere at 30%. I reset the phone, but instead of fixing the problem, it made it worse - now the battery level was shown at 0%, and again, keeping the phone plugged in had no effect. The phone was simply not charging. Now every time I was unplugging the phone it displayed notifications that battery level is too low and I should plug it back in.

I searched the net and I found that other users had similar problems, and the “fix” was to return the phone to the carrier provider for a refund/exchange. Ugh. Then I found another user who fixed his phone by resetting the phone in diagnostics mode. Fortunately his solution worked for me, too. Here it is: Start the phone application and show the keyboard Type ##634# - this enters the phone diagnostics mode Type *#2*# - this displays the battery information. All the numbers on the first page in the (MV) section were shown as 0% or 0mV. Now reset the phone (by keeping pressed the power button until the phone turns off, then press it again to turn the phone back on) After reset, the battery level started showing 100% (it was about time, after being kept so long plugged in), and re-entering the battery information diagnostics page seemed to agree – now it was showing non-null numbers, all good.
