Hey everyone seems like this post got a a fair amount of attention. just wanted to provide a little bit of background...
When I first got the Note 4 the battery life was, as is usually everyone's case, pretty dang excellent. over time it stayed that way pretty reliably. once the lollipop update came out for tmobile though, I went ahead and downloaded it straight away and I immediately noticed A) worse battery life and B) notably laggier performance at times. So I stayed with lollipop for about a month or so before deciding to downgrade to the KitKat version of Android... doing so was kind of a process, I mean I had tinkered before with rooting and all that technical stuff on prior devices but it is always very convoluted and you need to be familiar with all that lingo if you even stand a chance at doing it. anyway, I successfully did it and subsequently reinstalled all my apps. there were a few inconsistencies between lollipop and KitKat on the Note 4, like the S Health app (which I do use) and the overall look like in the lockscreen, but it wasn't really enough to persuade me to go back. after all, the reason I downgraded was to get better battery life and performance. that being said, I did notice the difference. fast forward a month or so and I download lollipop once again to my Note 4. reason being, I liked the interface better, and some of the stuff like S Health versions being different across KitKat or Lollipop got annoying; I prefer the functionality that the Lollipop version had. Anyway, so I updated and everything seemed to be kind of ok. My battery life was notably worse, but marginal enough to muster. I didn't really care all too much, and besides as I said I liked the UI better. So lately I've been noticing the battery life was just a bit underwhelming. Leaving it on my desk while working on my pc, leaving it off the charger overnight, and just generally not using it, I've noticed that the standby time is just awful. Now I'll admit that I have a lot of apps on my phone, (around 200), but I've installed most of them without really seeing an effect on standby time/ wakelock issues. Until recently that is. An important thing I think I should state is that I checked the 'up time' in the settings of my phone and I had gone almost a month without turning it off. If I remember correctly it showed that I had been using the phone without powering down for around 600 hours. But that changed when my phone inexplicably started getting power drain issues, so I had to turn it off and hope that would fix it. It didn't... The other day I was using my phone, went out to my cousin's house, was commuting via metro... Anyway, point is I was out all day. Never before had my phone died on me, until that day. I stopped using it when it alerted me that it was at 5% and before I had the chance to plug it into the charger, it had died. This really alarmed me and made it very clear that something on my phone was totally acting up, because even before when I would use my phone all day, I would NEVER have it die on me. Ever! Even when I had a Nexus 4 years ago with terrible battery life it could still get me through at least a school day and I'd charge it when I got home. What I'm trying to say is that I've come to expect a certain level of battery life from a phone, and grow accustomed to that threshold accordingly so I know if I have to take a charger with me somewhere if I'm going to be out for more than my phone can stay alive... So this is a pretty big change for me unfortunately. I've come across bad standby time before on phones, but those times were always just Google Play Services being wonky, and the issue would usually resolve itself within a week or so... but this time (from the screenshot) when I noticed such blatantly terrible absolutely unacceptable standby time that is obviously due to a wakelock, I was so irritated. So here I stand...
Some stats from the past few days: I just picked up my phone from it being on my table for about 5 hours off of a fresh charge, and the battery is at 90%. That's a drain of about 2 percent per hour. That's OK, I guess... but seeing as how with an iPhone 6plus you sleep overnight and still have 95 or so percent in the morning is by comparison, notable.
Also, I downloaded Greenify on the app store as a result of this dilemma and installed it, disabled tons of apps, and so far I see not really much of a difference. But it's only been what, 2 or so days so far. Ultimately I hope this is just Google Play Services being stupid as is usually the case, but seeing 50 percent battery down the drain while the phone was literally doing NOTHING was so infuriating. If this problem arises again I'll make sure to post here again. Thanks for reading guys.
