Nokia E66: How strong is its battery

31. July 2008 at 12:52

The E66 has a strong 1000 mAh battery. However, it has also a big and bright screen. So, how strong is the BL-4U battery? To answer this question I’ve made a batterylog showing all operation( like music), time and the battery level. Before I started this batterylog, I charged the E66 the whole night, choose GSM as my network mode and set light sensor to middle. Besides I deactivate Bluetooth and WLAN scanning to save more power. At the beginning the E66 has 7 bars.
