hmmm since I upgraded my Note 4 to Marshmallow my battery is doing weird things. Its suddenly just went from 25% to 14% and yesterday it went from 15% to 4% in the blink of an eye. Is MM messing up my phone or is it just a coincidence and my battery has decided to mess up around the same time I updated my phone?

I might get a new battery if I keep the phone. Doesn't seem to have been fixed recently but I normally top the battery up throughout the day. Its only been a problem when I sit down in the evening and constantly use it on and off for 6 hours.

Just opened up my case to find mine's started bulging.
Any recommendations for a genuine or quality aftermarket battery for the Note 4 please? I'm a bit wary about crappy batteries/fakes.

Might give Anker a go, my only hesitation is I did so for my S4 and the drain was still just as fast. Common denominator? Samsung. I reckon over 90% of my time with Android phones has resulted in faster than normal battery drain

Virtually every Note 4 battery for sale on Amazon and Ebay are fake. The only seller I've found of genuine ones also includes the separate charger and has put up prices to around £30.
I recently bought an Anker battery and tested the capacity to be around 3230mAh which compares well with the genuine Samsung ones. I've only had it a month and I'm aware that feedback suggest a small number of people have a problem with them longer term but so far I've had no problems.

I have an Anker one in my Note 1 after the original started to bulge - been running over a year fine and lasts about 5-10% longer than the original.
Get random battery drain on both my Note 1 and Note 4 - definitely a Samsung/Android issue.
The Anker batteries are grand, no frills and do exactly what the standard battery should have, Ive been running one since October and no issues.

Thanks for the recommendations 
I shall go with the Anker. I've had cause to speak with their customer service dept in the past and more than happy should anything go wrong, they'd sort it.

If it helps Iv been on lollipop for ages and only changed to Marshmallow this week and since I changed to MM iv been getting the random battery drops. Never had a single issue with those until I put the stock MM update on so it must be a software issue.

Don't know if it helps but my new Anker battery was at 96% before bed and in the morning, around 9 hours later, 92%. Screen off but picking up emails and doing it's sync every now and then.

I noticed after upgrading to Marshmallow on both Note 4s that the battery dropped unusually for the first couple of days then was fine after that. In both cases it was the 'media storage' process running and I assume it was cataloguing the media files on the Micro SD card. There's about 7,300 mp3s on the card so seemed to take a while.
I have also had large battery drops on a Moto G that took me ages to sort out. I eventually pinned down to a corrupt mp3 on the Micro SD card. Once I'd formatted it and reinstalled the media files it was fine after that.

Did you hard reset the phone, and clear the cache since you installed the newer Rom? If you haven't consider it.
Clean install for the ROM. It's definitely worse than before and the screen has yet to be at the top of battery usage, which has always caused a faster drain in the past. Currently on 15% (near full charge since 9/10am) with 2hr41 of SoT.
