I had the opportunity to lay my hands on an E71 while having the E75 with me. So I did some comparison between those two. It seems both the handsets are almost similar in functionality. for example both has this duel mode switching (Business & Personal), the voice aid feature which can read certain things to you, read your messages, read out numbers as you dial them. I use to wonder if it was unique to the E75, later on I found out it is there on the E71 as well in some other Nokia phones. Since both E75 and the E71 phones are targeted towards business users. Nokia has included VPN software also PTT (push to talk), SIP (voip), Instant messaging software on both the devices. You also get a version of QuickOffice that allows you to create office documents such as Word, Excel and PowerPoint where as on Nseries you only get a version that lets you view documents.
Physical appearance wise there’s huge difference as we can see. E75 is a side slider and the E71 is a monoblock. E75 is a lot narrower than the E71. Thickness wise, E71 is a winner. I feel E71 is much more pocketable in your shirt pocket than the E75. Maybe because its 12g lighter that the E75.
Technically, the E75 runs on Symbian OS v9.3 and the E71 on an older version of the Symbian OS, that is v9.2. Platform wise both on the same S60 3rd Edition. E75 is making use of Feature Pack 2 while E71 is on Feature Pack 1. The difference between the two FP’s is that FP2 boast features like advance power management, nice menu transition effects and the clock on every screen.
Web browser, both seems to have the same OSS browser.
Multimedia wise the E75 is one step ahead, even though both sports 3.2 Mega pixel CMOS sensor and 2048 x 1536 camera resolution. Why? Because the E75 has 640 x 480 video recording resolution with a frame rate of 30fps in comparison to the E71’s 320 x 240 with a 15fps. Also the E75 supports AAC audio recording where as the E71 supports AMR audio format, plus the E75 has a dedicated camera button on the side. To take a picture with E71, you need to use the D-pad.
In terms of Memory, E71 boast a much higher memory capacity than the E75. I wonder why Nokia decided to have only 50MB of internal storage on the E75 while the E71 has a storage capacity of 110MB. On the other hand E75 has a hot swapable Micro SD card slot which supports up to 16GB compared to the E71’s 8GB. Processor wise both has the same single ARM 11 type CPU with a clock rate of 369 MHz.
Talking about connectivity, the E75 comes with the standard 3.5mm AV jack, while E71 has the 2.5mm headset jack. The E71 has the Infrared connectivity, but I doubt people use that feature anymore. Except for these all the other connectivity features are kind of identical.
Coming to power management, upto 12 days standby time for E75 and 17 days for E71. That is mainly because the E71 has a powerful battery – 1500 mAh, E75 has a 1000 mAh.
A few of other extra features I see on the E75 which I think has an advantage over the E71 is, Accelerometer Sensor, Firmware Over The Air (FOTA), Stereo FM RDS Radio, USB Charging, N-Gage application support.
I don’t have any complaints about the keyboard layout of both the devices. Except it’s easier for me to use the E71 keyboard with one hand.
