4. Performance, Battery Life, Storage & Essentials

Performance

Lumia 640 is powered by Qualcomm’s Snapdragon 400 processor with 4 cores clocked at 1.2GHz. The chipset has been in the market for years but it has proved that it is reliable. Moreover, Windows Phone is a more efficient operating system as compared to Android so it does not require powerful hardware to run smoothly. The combination of Snapdragon 400 processor and 1GB of RAM is sufficient for Lumia 640 to handle pretty much everything. There is no lag spotted throughout the operating system and most of the applications.

Changing between smaller applications is quite fast as the applications do not need to be loaded all over again. The resuming transition window will only appear for larger application such as games. Thus multitasking on Lumia 640 will not be frustrating.

However, there is still a noticeable gap between Lumia 640 and other flagships. If the application is huge, the app loading time can be a little longer. Games with heavy graphics like Asphalt 8 are playable but frame skips will be present from time to time. The visual effects rendered is not as nice too.

Lumia 640 is performing as well as its competitors with the same price even though the hardware might be less attractive on paper.

Nevertheless, I think that the Lumia 640 is performing as well as its competitors with the same price even though the hardware might be less attractive on paper. We really need to forget about the specifications and focus on the experience the phone gives. It handles normal task like a champ and performance shouldn’t be an issue at all while you are making your choice.

Battery Life

Lumia 640 has a 2,500mAh battery and that capacity is pretty common for a phone like this. So how long does it last? Well, that depends on what you are doing. If you are using the phone for surfing the web and for social media with either WiFi or cellular data turned on, you can expect the phone to last one and a half day. If you are a light user, having the phone to last for 2 days is highly possible.

Regardless of what kind of users you are, topping up the charge every night will be sufficient and you should not have to find a plug in the middle of the day.

If you are playing a lot of 3D games and you watch a lot of videos, the phone can only carry you through a day. It seems that workload that utilizes the GPU a lot will not be too friendly to your battery life. However, I did not have the phone running out of juice before the day ended before, even if I played a lot of games. So regardless of what kind of users you are, topping up the charge every night will be sufficient and you should not have to find a plug in the middle of the day.

Of course, there are much more ways to increase the battery life. You can turn off the SensorCore to stop the phone from tracking your data. You can also disable Glance Screen, Location services and Cortana too. You also can disallow certain applications from running in the background. Fortunately, these steps are not necessary as I didn’t have to turn off all these useful features of the phone to last me through at least a full day. Even if worse come to worst, you still have Battery Saver mode to squeeze more battery life for you to survive through the day.

Storage

Lumia 640 comes with 8GB of internal storage with half of it available for you to use out of the box. That is not a lot of storage here and you will hit the ceiling in no time. There are a lot of applications being installed out of the box, like Skype, Weather, Travel, Food & Drinks. These apps did take up some place and you are free to delete them to free up more space.

In additional to that, the micro SD card slot is there for a reason. Up to 128 GB of micro SD card of storage is supported so if you are willing to pay the price, storage will not be an issue. For me, a 16GB card is sufficient to store my apps, videos and music. Yes, unlike some of the Android phones out there, applications can be installed on the external memory card. This feature is supported by the operating system natively and the performance is not hampered by it.

Storage is typically an annoying problem for low-end phones (and some of the high-end phones too) after some time of use. Since you can put almost everything on the SD card, I don’t think you will have any issue with storage if you opt to buy the Lumia 640.

Essentials

Lumia 640 is a phone after all. It handles the phone calls pretty well. The earpiece sounds okay and my friend can hear me well from the other end too. A Lumia 640 bought from Malaysian market will support Dual SIM and you can insert two micro SIM card into it. LTE connection is supported with all bands in Malaysia covered. If your area supports 4G LTE, you can expect a good connection from the Lumia 640.

Other connectivity options like Bluetooth 4.0, WiFi 802.11 b/g/n and GPS are supported too. NFC is present on this phone too, which is uncommon among devices with this price, but the usefulness of NFC might vary across different users. GPS works quite well as it can locate me fairly quickly. With Here Drive+ and Here Maps supporting offline maps, navigation is easy and costless. I cannot appreciate it more during my trip to Vietnam where I have very limited cellular data quota.

For those people who care about the audio quality, you might be disappointed. The speaker is placed at the back and it can be easily covered when you are holding the phone. Placing the phone on a surface will also muffle the speaker too. The speaker itself can produce acceptable audio at low to middle volume but you can hear the audio being clipped off at high volume. It is quite loud so you can hear the notification sound alright. However, you should use a pair of earphones if you are in the public. Granted, the speaker is just like other phones within this price bracket, it is neither exceptionally poor nor standing out.
