[Q] Battery dying pretty quickly while charging topic

I switched to CM12 about a week ago, and it's been fantastic. I use a lot fewer apps now as well since I cleaned up what I had installed/running when I made the switch. Now, however, my battery will drain really quickly when I have it charging and I'm doing anything else at the same time. For example, I currently have it plugged in to the wall and I've been watching some YouTube videos. In the past 15 minutes I've gone from 15% to 7% battery. Titanium Backup is running a batch backup in the background as well, but I experience this problem whether TiBu is running or not.

I'm using the power plug that came with the phone but the actual USB cord is from my Chromecast. (The cord shouldn't matter though, only the power adapter itself.)

Does anyone have any ideas? I do keep CM12 updated with the latest nightlies.

My new battery dies really quickly from 100% to 85% - any advice? topic

Hey guys,

I replaced the battery in my N5 because it was dying insanely fast (like 1.5 hrs SOT and 8 hrs uptime). The battery lasts quite well now (certainly much better than before), but it drops from 100% to 85% really quickly before discharing as normal.

I think my phone just doesn't really know the right percentages anymore - is there any way I can reset this software wise, or is it hardware? I know wiping the battery stats .bin file is controversial, so I wanted to see if there's an actual way to do this that's proven to work

any help would be awesome
