Battery lasts very bad (about 3-4 days), although it should be new and I only write SMS and very rarely on the phone. Since my old battery has not kept poor (more than 3 years old). At first I thought it should be few times to fully charge the full power comes, but it has not improved. If a warning sign of niedigen battery status comes, then the phone is made very quickly. This is a mystery to me why a "new" battery of Nokia has such a poor performance.
