First of all I want to say that it is not the regular le1s which faced many problems. It is the refined model le1s eco. Lets talk about that-
Design & build quality-
Design of this phone is pretty simple from frontside and backside.
And about its build quality.it is simply the best phone in terms of build in this price range. The metal housing and attractive colors with shiny fingerprint scanner on the back.
Components-
Display: It comes with a full HD IPS display of 5.5 inch and with 403ppi, which makes it pretty sharp. And color reproduction is also good
CPU & GPU - It is powered by 1.85 GHz octacore mediatek helio x10 processor which is a bit lower than le 1s( 2.2GHz) , but seems fast. It heats while usage and while using camera. So I think instead of helio, snapdragon is a better choice. The powervr 2000 GPU is good but not suitable for heavy games like NOVA 3 etc.
Memory- It comes with 3gigs of ram and 32gigs of internal stroage. But it has no external SD slot.
With the preinstalled apps and its ui it simply manages to give you 1.2- 1.6 gigs of free ram
Os- It has a preinstalled android lolipop5.0 and its customized EUI user interface. But I think eui is a bit different than any android phones in this segment and also not so easy to use for all people.
Battery- it has a 3000mAh non removable battery which is ok ok.it hardly manages 1day of battery life.
Conectivity& communication- It is a dual sim phone which having micro slot for 2nd sim and nano for 1st sim. It is a 4G device but not with voLTE. It is having wifi, bluetooth, FM, 3G, 4G, GPS, IR Blaster for communication
Sensors- It is having sensors like proximity, ambient light, IR Blaster, Acclerometer & Gyroscope sensor.
Camera- The 13mp rear and 5mp front is just average. I personally doesn’t like this camera.We aren’t expecting this from leeco in camera
Sound & audio- Here I am impressed with this phone. The loudspeaker provides good and loud audio and while using headphones it is really good. The voice quality of microphone is also good.
Usb- It comes with usb type C charger and cable which is fast & a quick adapter to charge this phone.
Fingerprint- It has a good fingerprint sensor which having good and shiny design. It is also fast.
Conclusion-
It is a good phone with build quality but its processor is not good as its main competator, redmi note 3. Also the Powervr 2000 GPU is not good than adreno in redmi. Camera of redmi is better. Fingerprint sensor of this phone as compared to others feels like a little slower but it is unnoticable. The IR blaster is good and works well.
All the way it is a good phone. I recommend it. But if u r a heavy gamer and multi tasker then go for redmi note 3.
