Battery Full [Q] INSTANT battery drain from 40% to 0% following RMA. Help please

Hi, I recently RMAd my nexus 5 for a sudden death which required a new PCB. I've had it replaced about 2 weeks ago and last night a similar thing happened. I had about 40% battery and it instantly turned off so I feared the problem recurred, however this time I am able to charge it up again and it seems to be working... Is there a fix for this? Could it be a possible miscalibration of the battery since the RMA, or should I sent it back again? See the screen shot for the battery stats. I am running stock 4.4.4 and am not rooted.

battery stats

Cheers

You can try to fully charge it, then delete /data/system/batterstats.bin and reboot.

This is not the problem you posted about, but your phone isn't sleeping very well. Will take a look at a BBS log if you post one. Also, not too sure what's going on with your signal...

Honestly, I'm not sure. I think not, but you can try.

OK cool. I'm reluctant to root as I may take it back to the shop and I don't want to unlock the bootloader. I can't post BBS without root either

If your signal is very poor and you're on data....then battery can drop like a rock. And faster the more apps you have that are trying to sync over data.

Just so you know.

Also, sometimes things get stuck and suck your battery dry if not caught. Usually a reboot will fix it. If it only happens a couple times....that's what's happening.

Need help with poor battery life on the N5...or any device really? Lots of info in first 4 posts! >>>>

Mm I understand but surely it couldn't cause it yet drop from 40% to 0% in a matter of seconds. I would have felt it get hot if that was the case

Calibrate and see how it goes.

And why is that? BetterBatteryStats has an option to use root features if you want. In advanced settings. So install it and see how it goes. You're probably going to want to take a look at partial wakelocks to see what's killing your battery.
