Large variance in reported battery life due to overheating?

Tip us?

Hmm, I dunno if I'd say it is painfully hot (thought when trying to wireless charge and use it it gets pretty bad) but certainly quite noticeable. What was the temp in degrees Celsius? I see 70s on the phone and 40s on the battery quite frequently.

Phones that get hot to the touch are actually doing a good job dissipating the heat. Though it may become uncomfortable to be absorbing some of that heat it does have to go somewhere.

Nexus 5 uses aggressive thermal throttling to keep the phone fairly cool and according to Anand has a heat spreader between the SoC and battery unlike the Nexus 4 which caused the two to heat up quicker.

The only thing that will stop me from getting over 4hrs SoT (3.5 - 5 based off usage) is if an application decides to keep the phone awake endlessly. I've seen it happen for Google Search and a few others randomly at times. Reboot or force stop fixes that up.

My nexus 5 battery also seems really crap, and the back gets hot very quickly. Everything else on this device is 100% perfect. Ive tried everything i possibly could (Different kernel, undervolting, lower cpu freq, change governors, low brightness, most connectivity settings off, ok google off, and many more battery saving aspects) yet i still can only get around 2-3 Hours sot with light usage (XDA, web browsing, social media). Is my device somewhat faulty? Or is it supposed to be like this? And normally when i play games, it drains at a speed of a percent per 40-60 seconds.

And please dont go about bashing me, im just a bit curious on how people get around 6 hours sot.

I haven't really had to do this on this phone, but I used to chase Screen on battery drain issues with Cool Tool from the play store. It floats a highly configurable window on the screen that lets you monitor a lot of system parameters including current draw - which is probably what you are most interested in here. I think you can also monitor the temp of the device, the cpu utilization, etc., etc. This lets you play with different settings and what not and get more immediate feedback as to what is happening with your device. In the screenshot, I configured the floating window only to show current draw...should be the pink 182 mA.

Thanks for that link but am I right in assuming most of it's functionality won't work correctly in KitKat? That has been reported with most battery or CPU monitoring apps so far.

I've been looking for something to show me current draw on stock but have only had battery widgets show me the current battery voltage which I don't understand the significance of. Starts at 4300mV when 100% and drops to about 3900mV when nearing empty.
