Thanks for the info. Wt is the cost of nexus 4 when you bought it?
Bought mine for 25k
The only problem with my Nexus 4 is that the battery doesn't last much in wi-fi.
If I keep using nonstop it lasts only about 6 hours. :/
Can anyone please find out which custom ROM, kernel and any other modifying stuff would be the best for boosting battery life? Till date it's pure phone out of the box.
Yes, I agree...the battery life is not the best. But considering that its running a big screen with a power-guzzling quad core processor, it is average I would say. You can increase battery life significantly by changing the kernel. Since most power-saving and scheduling is dictated by the kernel, it is enough to just flash a custom kernel even on stock ROM. Just root and flash franco's kernel from XDA and enjoy better battery life.
another problem with Nexus 4 is it heats up pretty fast
Yes, it heats up. But it heats up just as much as any other phone. The effect is more pronounced because of the glass back. Thermal conductivity of glass >> plastic. And this heating is seen on all phones with the S4 krait processor. Qualcomm's closed-source proprietary "MPDecision" governor is not doing a good job, as explained by
faux, one of the kernel developers on XDA. Qualcomm stated that it will fix this in one of the later android revisions. Read more about it in the link below:

Flashing a custom kernel greatly reduces heat by using better governors and under-volting tweaks. Also remember that the nexus 4 internal design is such that the heat is quickly transferred to the battery which then causes the device to throttle(throttling occurs according to battery temp). Higher battery temperature means higher resistance which equates to battery draining more quickly. Still rest assured that this heating is not a nexus 4 specific issue, it is a combination of the glass back and qualcomms governor. Infact the xperia Z heats up just as much and throttles even more than the nexus 4.
Check the Youtube link below, it gives a good idea of what the relative temperatures of 5 phones running stability test: LG Nexus 4, Sony Xperia Z, Samsung Galaxy S 3, Meizu MX2, Sony Xperia T.

I was most interested in the comparison between the Nexus 4 and the xperia Z since they have similar specifications with same SOC and amount of RAM. Also both have glass at the back and voila, both heat up nearly the same. Infact the Xperia Z underclocks to as much as 702Mhz to maintain temperatures, while the nexus only lowers its clock rate to 1134Mhz. I have compiled below a brief synopsis of the video in an image:
As can be seen, the nexus 4 has slightly higher temperatures, but is also running at a higher clock frequency which explains the higher temperatures. The good part is that the Nexus did very well in the benchmarking aspect of this test. The scores are number of runs per core and RAM(core 1, core 2, core 3, core 4, RAM). The Nexus has more runs and hence is the best performer. I have personally run Stability test and the temperature after 15 mins was 45.8C which is good considering its summer now
