Karbonn K451 Plus Black - Expert Reviews


It has been four years since Karbonn telecommunication firm was launched in India and the Bangalore based firm has done reasonably well in the market making Nokia stretch so as to finally lower the prices of their budget devices too. But it's not like the company has ruled the roost with Micromax gunning down their throats at all times and eventually taking a better market share. Another point that has helped the tier2 companies like Karbonn is the advent of the Android operating which becoming open source puts all the companies on the same pedestal at some level. But Karbonn K451 Plus is not a device that is abcekd by the Android operating system and has the dimensions 116.5mm by 51.9mm by 14.6mm with a miniscule screen of 2.4 inches that gives a resolution of 240 by 320 pixels which is also the minimum that you can get. Powered by a standard lithium ion battery of 1,800 mAh, the power backup is one feature of Karbonn which would make it standout over the other devices as the device is meant for those who are more interested in talk time offered by the device rather than high profile games and apps. The internal memory of the device  is low with 128MB which although would be sufficient for storing contacts and phonebook information.


The user however can use the microSD card slot that allows the user to expand the memory of the device up to 8GB. Data connectivity features are rather restricted with Bluetooth and USB port but there is no access to Wi-Fi but this does not mean that the user cannot access the web as there is the facility of GPRS and WAP browser that makes sure  that Internet facilities are available although the speed may not be that great, in fact on some occasions very slow. The device being Dual SIM allows the user to keep two separate SIM's in the same device which again shows that this is a utility phone and not for the flashy gadget lovers. Multimedia features include the music player and the video player where the sound quality for the former is okay at best when it comes to loudspeakers but improves when used with earphones. Some of the other features offered by the device includes STK, Wallpaper, Power On/Off Animation, Back light of keypad, Call Conference, Anti Theft Feature, Languages (English & Hindi), Calculator, Alarm Clock, Stop Watch, World Times, Speed Dialing, Organizer, Voice Recorder and Currency Converter.

Operating system and UI

Karbonn K451 Plus has a 2.4 inch screen that gives a resolution of 240 by 320 pixels and can be interacted with through the alphanumeric keypad.

Other Features

Karbonn K451 Plus offers a music player which allows the user to listen to songs in the formats of MP3 and MIDI. There is also the video player that makes sure that the user can watch desired videos in the formats - MP4, 3GP and KMV. FM radio is also provided for listening to the popular radio stations.


Karbonn K451 Plus has a 1.3 megapixels camera that allows the user to click pictures at a resolution of 1280 by 1024 pixels. The user can also shoot videos but the quality of pictures and videos shot is low to moderate. One should not have high expectations from the camera of Karbonn K451 Plus as its primary purpose is to give a substantial amount of talk time.


Karbonn K451 Plus has the WAP browser and the GPRS facility to enable the user to access the web and download data or visit the desired web sites like Facebook and Twitter. The browsing speed is on the slower side in normal circumstances so opening multiple tabs would be highly incontinent.


Karbonn K451 Plus comes with a internal memory of 128MB and although the amount looks small, the presence of a microSD card slot makes sure that the user can expand the mempry of the device up to 8GB so that the user can store loads of data including songs, games, images and videos.

Other Features

The games and apps offered by Karbonn K451 Plus are pretty limited specially when pitted against other Android devices simply because this is not a Android handset. There are few games and if one looks at them within the spirit of a budget devices, they can be pretty handful.


Karbonn K451 Plus is backed by the standard lithium ion battery of 1,800 mAh that makes sure that the user can get a talk time of up to 8 hours along with a standby time of up to 500 hours which is a significant improvement over the previous edition.


Karbonn K451 Plus has limited data connectivity features including the bluetooth feature that allows the user to connect the device with other devices and exchange data with it where the data exchanged may include music files, games, images and videos. There is also the USB port that enables the user to exchange data via USB cable where the data exchanged can be done with computers and laptops. Wi-Fi is absent but GPRS and WAP browser is available.

Other Features

Karbonn K451 Plus when compared to Karbonn K451 has improved a lot with a bugger screen of 2.4 inches where Karbonn K451 features a 2 inch display. The battery strength has improved significantly giving twice the talk time and twice the standby time as compared to its predecessor. Both the devices support dual SIM and have the FM radio player but the microSD card in Karbonn K451 had a potential of 4GB for memory whereas it can be stretched up to 8GB for Karbonn K451 Plus.

Other Features

The tele-communication war goes with the user benefiting getting all the features in their devices at a economical price. At least that is one way of looking at it, for some it means the high profile companies over pricing their products simply because they can. Karbonn K451 PLus is a budget device and has all the features that a utility phone should have like a camera, FM radio, music player, dual SIM and a long lasting battery. Will Karbonn be able to topple other companies like Micromax is another story, but let's hope for a good fight.
