ASUS UX51VZ Battery
The laptop uses a 2.0 stereo system made by JBL to render audio. Both speakers have 4 watts at their disposal. Overall sound quality is very good, so that obviously the resonance chamber is large enough despite the 770Z5E's slim profile. Even positioning the speakers underneath the device didn't have any negative consequences, so that we definitely do not have to advise potential buyers to look for an external solution. For most purposes, the integrated speakers of the 770Z5E should be more than adequate. ASUS ZenBook UX51VZ Battery
Of course, it is still possible to plug in a headset, external speakers or an AV receiver via the 3.5 mm Line In/Out or the HDMI port. Transmission quality is great - the resulting sound experience thus only depends on the peripheral equipment. ASUS ZenBook UX51V Battery
Power Consumption
Thanks to its modern components, the Samsung laptop doesn't use too much power despite of its more than decent performance. 8.6 to 14.9 watts can be expected during Office tasks. This is just slightly above the power consumption levels of modern ultrabooks with an ULV processor and an integrated graphics unit. ASUS ZenBook UX51 Battery
Power consumption increases strongly under full load, with stress test (Furmark + Prime95) values of up to 88.5 watts, which is still below the threshold of what the power adapter can supply (the larger 770Z7E-S01DE, on the other hand, crosses this threshold of 90 watts). In total, power consumption levels are still acceptable.
The 91 Wh battery is permanently installed, but at least well-dimensioned. It provides the basis for decent battery life values, which we will analyze in the following section.
Battery Runtime
The Battery Eater Reader's Test simulates reading a text document on minimal screen brightness while being in airplane mode. Thanks to its large battery, the 770Z5E manages to stay alive for up to 15 hours and 45 minutes, while the larger 770Z7E-S01DE and the 700Z5C with its smaller battery barely scratch the 10-hour-mark. Only the Apple MacBook Pro 15 with Retina Display fares better with almost 18 hours. A negative example would be the Asus N56VB-S4050H with just 5 hours of reading time. ASUS ZenBook U500VZ Battery
The other extreme can be examined while under full load. We use the Battery Eater Classic Test, while activating all radio modems and turning the laptop's screen brightness way up. The 770Z5E manages to squeeze 1 hours and 53 minutes out of its battery, approximately the same as its predecessor, the 700Z5C. The Samsung Series 7 Chronos 770Z7E-S01DE (66 minutes), the Apple MacBook Pro 15 with Retina Display (88 minutes) and the Asus N56VB-S4050H (58 minutes) all perform worse.
A realistic estimate can be gained through our "surfing on WiFi" measurement, where a script opens a new website every 40 seconds. Screen brightness is set to a standardized 150 cd/m² in order to create reproducible as well as comparable conditions. We measure 10 hours and 42 minutes for the 770Z5E. This is a very satisfying result, exceeding the runtimes of all other laptops mentioned above. Our overall impression of the 770Z5E's battery life is therefore quite favorable.
