    The battery life hasn't changed from before but B Diddy said to give it time

    I'll soon find out if my phone just switches off in a bit by itself

    I used my Lem Samsung Note 4 battery that was provided by AT&T for about a year after about a year my battery started to hook the drain to 40% pretty often once my battery would reach 40% the phone would just suddenly die. I was looking online on amazon.com and found that the company Anker sells third-party batteries I purchased two of these that came in a pack of 2 and a wall charger together. These two batteries have been sufficient for me as one battery provides a full charge all day I only have to change the battery at night in the evening

    After about a year with having my Note 4 phone the OEM Samsung battery became faulty and found that these Anker batteries became a good

    You think? I got a new battery already and it just lasted exactly as long as the old battery I got would

    OK update, the battery drainer in my phone is "Android system"... What do I do here?

    I looked into the Anker batteries too, like I said, I think it's something in the software that I'm missing

    It'd be helpful to see those same screenshots that were requested earlier in this thread, as a comparison. Was the screen on for a long time while you were waiting for the battery to drain, or was it asleep for most of the time? What percentage of battery is Android System using? System is always going to use a decent amount of battery, but if it's upwards of 80-90%, then something is clearly not working right.

    The android system has reached 50% before, and I don't know why the phone stayed awake last night? Drained it from 80% to 17% overnight

    You need to post the "entire" first screen. All the stuff below is cut out... unless there's nothing else there. Scroll down and post all the apps being reported by battery usage, no matter how low the usage is. Just because an app reports very little usage doesn't mean it's not draining the battery through Android System/OS.

    Secondly, start your phone in Safe mode and run it that way for a while. You mentioned that sitting on your desk for 10 minutes lost 5%... see what happens in safe mode for 30 minutes. To get into safe mode, press the power button like you want to turn off the phone. When the Phone options menu appears, "press and hold" Power off and select to turn on in safe mode. To get out of safe mode, simply restart the phone.

    Safe mode, did not think of that!

    Okay I'll post all of the first screen but it's on charge right now so I'll have to wait until it gets low on battery again.

    What do I look out for in safe mode?

    All safe mode does is disable apps you installed and only allows system apps to run. It's just a troubleshooting thing to help find out if it's an app you installed causing the issue. Snapchat is a prime suspect... it's been posted, in the last two months, about it causing issues. Not saying it's that, but it's possible.

    Edit... you may have to wait awhile before posting until you notice the same battery drain. Posting the battery stats directly after full charge may not show anything as the stats get reset.

    I did remove snapchat, Spotify, emoji keyboard and pokemon go to see if the battery drain would happen and it would (That was all my downloaded apps).

    It's been like this since I got it and it was a used phone when I got it, is it safe to say that if a hard reset don't work then I need to get a return?
    I've got two weeks from today left to make a return if I wish

    Also, the phone did come with the startup screen and stuff so it was reset previously

    Well, since you uninstalled all your apps, that kind of nixes safe mode. You might give it a try anyways to see what'll happen.

    Lately, in the last month or so, Google apps... almost all of them... have been having problems. I'm not sure what the status is with their apps currently, but it could be one of the updates Google pushed to your phone. There are tons of threads about Google apps messing up peoples phones... including battery issues. What you could do is uninstall all Google updates... all of them at once... and then force stopping and turning off all Google apps. This is not to say you always need to run your phone this way, but for troubleshooting purposes only.

    is it safe to say that if a hard reset don't work then I need to get a return?
    Absolutely! A factory reset will take your phone back to original OS state. Even Google updates won't be there. If the phone still messes up, you definitely should return it.

    By the way, there is one particular thing that Google Play Services was doing lately (and not to all phones), but it was continually increasing stored data for no reason at all. Gigs of data! You might check the Google Play Services app in Application Manager to see how much data the app has stored on your phone.

    I was reading about the Google apps but when I checked the settings, nothing seemed unusual to me

    A while ago, I disabled SOME Google apps but not all in case I mess up the phone (Gmail, G+, Chrome etc)... I kept the play services and a few others that I was unsure of stopping.

    A factory reset isn't a sure fix in my situation since it was factory reset before arrival but well worth the try as it would be factory reset if I have to return it anyway.

    EDIT: Google Play Services has used 3.67mb of data since 18 July, is that more than its supposed to?

    You can actually turn off all google related apps if you wanted to. Naturally, apps that are dependent on google apps won't work as intended. However for troubleshooting (or semi-permanently), it's not a problem.

    I also own a Note 4, by the way, and I normally have all google apps turned off. No kidding! No google apps run on my phone and tablet until I turn them on when I need to do something. I hate that google always needs to start, run, call home, update, etc. It's a small hassle having to turn stuff on and off, but google is actually a pain in the arse to me! But that's me!

    EDIT: Google Play Services has used 3.67mb of data since 18 July, is that more than its supposed to?
    3.7mb of data is fine. People with problems were seeing 12+ gbs!

    Very true!

    If it's the original battery I'd just suspect it to be normal battery deterioration. Batteries under normal usage/stress are expected to start deteriorating in capacity in about 12-18mos. Abuse hastens this as well. The Note 4 is nearly 2 years old.

    I'm just going to factory reset it sometime, got nothing to lose except Spotify and Snapchat after all!

    The battery deterioration isn't the problem I don't think as I've tried a new battery, I also don't want to spend more cash on an Anker battery as this would mean I'm spending even more money on something I'm not sure will be the fix.

    How common is this kind of battery issue for Note 4 users? And does a factory reset work normally?

    My Note 4 is 20 months old. With the original battery, and when I'm taxing it running various apps, games, texting, email, phone calls, watching videos, etc, it can last me a few days, with screen on time around 4.5 hours. If I'm not taxing it at all, just text and phone calls, it can last on standby for 5 - 7 days. The reason my battery can last that long is because I don't sync, my wifi, data, and location are off when not in use, and I don't use any cloud services, or social media. I also have two other batteries I swap out about every two charge cycles. I normally only charge once in my phone (the second charge is done on external charger), and that's at about 40%... rarely lower. I just charged my battery a few minutes ago at 42%... the phone had been on low usage for 5 days 19 hours.

    Battery issues have a lot more to do with how you run your phone. Taxing the battery will certainly age it faster due to the number of charge cycles, plus the heat of charging. And, allowing the battery to get too low before charging it can also cause premature failure in lithium batteries. Some people say 30 - 40 percent is a good safe place to start recharging. I actually Vape, so I know how to kill a lithium battery... I also know how not to kill one!

    As for a factory reset, I've never had to do one in 20 months of owning my Note 4. On my Note 10.1 2014 tablet, I've done one factory reset due to my own stupidity of disabling keyguard by mistake when I was debloating it. The keyguard app handles your password/pin, and if you have one set, and you disable keyguard, you get stuck on the lock screen and the only way to get back in is a factory reset! I can vouch that a factory reset works as it should. Hey, the best way to learn is by experience! LOL!

    That is true, allowing the battery to get too low before charging it up causes failure and that's what I try to avoid doing! (I think it's different for Apple devices but who knows)

    Well that's lucky you done a factory reset! So yes I will be doing one real soon, if I need to, I will get a return and refund which is a shame because this really is a good phone.. It come from South Korea to UK so getting it back will be a mission but I was sort of anxious as to if it would be a fake. Lucky it wasn't as I checked the IMEI on it but the battery is a shame

    Lots of good input from nahoku! The main thing I would add is that if a factory reset does nothing, then you could also try reinstalling the firmware. If the firmware has corrupted somehow, then a factory reset won't fix it, since you're still using the same firmware. To reinstall the firmware, try using Smart Switch: SmartSwitch: Install & update or replace firmware
