Call Time (2.86)
To test battery life during a call we make a call to the phone using Skype and play an audio book over the connection to simulate conversation. We tested the Nokia N75 using AT&T's UMTS network. The N75 performed badly on our call time test lasting only 2 hours and 23 minutes. This is the worst performance we have seen to date from a phone, slightly worse than the LG Chocolate's 2 hour and 40 minute time. The use of the 3G network has a major negative impact on the battery life as does the relatively small 800 mAh battery that the N75 uses. Compared to the Treo 750, which also uses AT&T's 3G network, the N75's battery life was an hour and a half shorter. Those who spend hours on their phone will find they will need to carry around a charger or additional battery with the N75.
Music Playback (4.03)
To test battery performance while playing back music we set an album to play looped at maximum volume until the battery expires. The N75 lasted 5 hours and 36 minutes in our test. This is at the low end of what we've seen from devices to date. It is slightly better than the Krzr K1m's 4 hour 22 minute time but came out worse than the LG Chocolate's 7 hour 37 minute time and the Sanyo M1's 8 hour and 12 minute time. Compared to other Series 60 devices the N75 did significantly worse than the Nokia N73, which lasted 9 hours and 51 minutes, and about the same as the Nokia N85's 5 hour and 40 minute time. Chances are that the N75 won't be able to play music all day long without dying on you, so again be sure to carry a charger and/or additional battery.
Web Browsing (3.24)
To test battery performance when browsing we point the web browser to a page that is set to refresh automatically every 10 seconds. The N75 was again tested using AT&T's 3G UMTS network and again it performed badly, lasting only 2 hours and 42 minutes. This ties with the Motorola Q for the worst browsing time we've seen from a phone to date. It is worse than the Treo 750, another phone running on AT&T's 3G networ, which lasted 3 hours and 3 minutes. It is also worse than the other two Series 60 devices we tested as the N73 lasted 4 hours and 6 minutes while the N95 lasted 6 hours and 8 minutes. We must say that we are deeply disappointed by the poor performance of the N75 on our battery tests. We weight battery performance heavily and this poor performance will have a significant impact on the N75's overall score.
Idle Time unscored
In order to ensure that we deliver reviews in a timely manner we do not test standby time for cell phones. Nokia's stated standby time for the N75 is 200 hours.
