For the last couple of weeks my battery indicator is messed up. Even draining complete and recharging to 100 doesn't solve the issue. Not even a firmware reinstall. Right now the battery jumped from 1% to 10% right after I plugged it in. Unplugged & rebooted and it jumped back 28%, and while writing this thread back to 11%. Send the diagnostic to Apple and they are claiming it's fine. Any other solution for my problem?
