One plus entered into smartphone business through this champ. One plus 1 is a budget-priced device aka Flagship killer considering its features the price which it labels is very aggressive. This champ runs on Snapdragon 801 clocked at 2.5 GHz and Custom four kryo cores. This is coupled by 3 GB ddr3 ram. Performance wise this is a beast. now battery. you would be thinking that due to high-end processor battery will be compromised so. Sorry, you’re totally wrong OP1 has a gr8 battery abt 5 hrs of SOT on stock rom. The display is 5.5 inched LCD @ FHD and 441 PPI. This display is good enough for pleasurable entertainment. The camera is also a good point here 13MP Sony Exmor rs. Which can capture amazing pics at indoor and outdoor conditions it can also record 4K videos and slo-mo videos. The front camera is also good with a 5MP resolution which takes good wide angle selfies and records videos up to FHD. It also has 4G and NFC. It is a developer phone so, rooting and CRoms doesn’t avoid the warranty. The only bad thing is call quality which is not up to mark don’t get me wrong it is not poor.
I will definitely suggest this phone
