The Nokia Lumia 930 specs is very good. It is one of those mobile phone which has good connectivity, loads of multimedia options and a very good high density (~441 ppi pixel) screen. Its a bit lower in price than the Lumia 1020 however it has a larger battery (Li-Ion 2420 mAh), better screen however some users complain that the battery is simply not going to do with a quad-core processor and all the bells and whistles that it offers.
The Nokia Lumia 930 has some impressive specifications. 20 years ago this would have been better than your desktop computer. With the rise in specs comes a faster drain on the battery. I am not certain why Nokia opts for non-removable batteries in some of their high end phones. One would think that this would be the first part of a high phone to go which would need replacement.
The Nokia 930 comes with coverage for all three networks. The 2G Bands (GSM 850/900/1800/1900) as well as the 3G Bands (HSDPA 850/900/1900/2100) and 4G bands (LTE band 1(2100), 3(1800), 7(2600), 8(900), 20(800)). It also features EDGE and GPRS with speeds for HSPA at 42.2/5.76 Mbps and also LTE Cat4 at 150/50 Mbps. Even though the phone was released in July 2014 its still an excellent mobile phone to have today.
The Lumia phones have a standard size of about 137 x 71 x 9.8 mm and the high end version also weight in at around 165 grams. The phone uses a nano-SIM and like other high-end phones from Nokia they come with an AMOLED capacitive touchscreen with 16M colors. The display is 5.0 inches with a very high screen resolution of 1080 x 1920 pixels with a pixel density of ~441 ppi, which is very high. As an example your budget phones are at about ~165 ppi. This gives you a good idea as to its sharp pictures and video. The multitouch screen is protected by Corning Gorilla Glass 3 and it has a Clear Black display.
The processor on the Nokia Lumia 930 is very powerful and much more than even many other high-end phones. It uses the Quad-core 2.2 GHz Krait 400 with a Qualcomm MSM8974 Snapdragon 800 chipset and an Adreno 330 GPU. The Adreno 330 is much more powerful than even the more expensive Nokia 1020 (Adreno 225) or the very popular Nokia N9 (PowerVR SGX530) mobile phone GPU processors.
The phone does not have a card slot for expansion however at 32 GB and 2 GB RAM I dont think you are going to be needing any more space than what has already been provided. The camera is a 20 MP Carl Zeiss optics camera. This also comes with a dual LED flash, autofocus, PureView technology, geo-tagging, face detection as well as panorama. With a powerful GPU and CPU the video playback is again a very impressive 2160p@30fps. This is also coupled with Dolby Digital Plus audio enhancement as well as active noise cancellation with a dedicated microphone.
The phone comes with Wi-Fi 802.11 a/b/g/n/ac as well as hotspot. Bluetooth v4.0, A2DP, EDR as well as NFC and A-GPS and GLONASS. There is also a FM radio and a USB version 2 port. The sensors on the phone includes an accelerometer, gyro, proximity, compass and sensor core. Messaging is covered well with SMS (threaded view), MMS, Email, Push Email as well as an IM. There is no Java and it has a HTML 5 browser ability.
Qi wireless charging (market dependent) is available so check with your dealer. The non-removable Li-Ion 2420 mAh battery (BV-5QW) comes with a standby time of Up to 432 h and a talk time of approximately 11 h 30 min (2G) / Up to 15 h 30 min (3G).
Overall its a very well balanced mobile phone. The battery is larger than normal however the phone does draw a lot of power when being put through its paces. The Lumia 930 is a good long term investment and a bit cheaper than the other options available.
