Comment 4 for bug 120549

I think that the battery level reporting is broken on the HAL side. In lmctl:
                printf ("\tBattery status: %d ", P5 & 0x07);
                switch (P5 & 0x07) {
                case 0: printf ("(unavailable)\n"); break;
                case 1:
                case 2: printf ("(critical)\n"); break;
                case 3:
                case 4: printf ("(low)\n"); break;
                case 5:
                case 6: printf ("(good)\n"); break;
                case 7: printf ("(full)\n"); break;
in the csr addon:
                                if (current_charge != 0)
                                        percentage = (100.0 / 7.0) * current_charge;

0 means unavailable, not empty (well, it might be unavailable because it's
empty, but that would only be useful if the previous level was non-zero). Makes
sense Richard?
