This only happens when its turned on, when i charge it while its turned off and turn it on after fully charging, it stays 100% for quite a while.
Also usually when im not doing too much on the device the battery lasts a good week.
Couldn't find any faulty services on the battery usage, i also close apps in the background when im done using them/not using them for next few hours.
edit: this drain happens while doing nothing on the device, within like 30 minutes, from there on it drains normally like a percent per hour in idle at most
That is the most vague question I've seen in a while. What are you doing when the battery is draining until 85%? That is the right question. If you have data on and you are using the phone it can happen in 30 min or so

well, nothing, i guess i didnt make it obvious enough, i remove the charger and 30 min later i check again its below 90% or 85% already but from there on it drains normally as in not much at all in idle
maybe like a percent per hour or so, not exactly sure

Hi, My battery used to stay at 100% for at least 20 min with minor use after taking it off the charger. Now, it drops fairly quickly to 97% with the same usage. Overall I think I am left with the same percentage at the end of the day, but I was wondering if anyone else experienced this.
How old is the battery, are you leaving it on the charger for long periods after it's fully charged. Their longevity wears down so it's going to happen. But you can take some steps to stretch it out to the max. Mine goes from 100% to 95-96% in about 30-45 minutes right now

Thanks, Its about a month old. It is on the charger for at least several hours after its fully charged. Also, I am completely stock.
Just curious, is your device idle in the 30 min that it takes it to go from 100% to 95%? If not are you doing intensive stuff to takes it to 95%?

Yeah mostly idle, just running back ground tasks and such. Very minimal use.
Also I think leaving it on the charger for long periods of time reduces the life span of the battery as well. That's why it notifies you to take it off when it's fully charged. And I believe I read that somewhere else also.
But also if you leave it charging all night the phone may say 100% however the phone to prevent it self from charging the battery to long it stops charging it and let's it drain from 90% to 100% and slowly charges it back up. So as not to damage the battery. It keeps following that loop to keep your battery running longer so the first 10% can sometimes be misleading but it's nothing to worry about

This was fairly common on the SGS2.
The common way to fix it on that device was to charge it to 100%, then unplug it and plug it back in and wait until it gets to 100% again. Do this 3-5 times and the problem should be gone. It is worth a shot on the SGS4
This can happen when flashing ROMs while your battery is not full, though this is not the only way for this to occur.
I like that last one. Gotta try it out.
The kernel stops charging at 100 percent and doesn't start again until it guys 95. What you're reading as your percentage level is not the exact levels
Say you unplug at what you think is 100 percent but in reality it's actually 98 percent, the software quickly relays this back to the user and adjusts the battery levels accordingly making you think it just drained 2 percent really quickly.
The whole reason it does this is to percent over charging the battery. That will greatly shorten it's life cycle or even worse blow up your battery

Something odd happened to me today.
I went to sleep listening to an audiobook, the G3 was at 100% battery.
When I woke up ~8 hours later the battery was at 99%, it was plaing audio the whole time.
Obviously a display bug, when I went to see battery status it said 648 hours left.
So I restarted the G3 and nothing changed, the battery is now at a lower % but it behaves as though nothing happened.
Please tell me the battery micro-controller isn't screwed and doesn't now report 70% as the new 100%.

I had something like this as well, but it went down a tick eventually. i was browsing reddit for 30 minutes at 100%, then it went to 99%. Not sure if it's just amazing battery life, or somethin'gs up.

I would drain it to 0% and then charge it to 100% without unplugging it. That should recalibrate the battery
From 100% > 99% seems to take an age. But soon as it hits 99% it does drain considerably faster.
If you check you batter after you have charged it, it always says Estimated time remaining and collecting battery info... please wait.. until it drops to 100%
I have same issue but its not bother me much. Whats bother me is that some times when I go to sleep and live phone at 60% I wake up tomorow and its 60% and sometimes drops like 3 or 5%...any one have that issue?

Well, it's hard to say but maybe it wasn't a problem after all.
Seems like the battery % is highly inaccurate at top levels. 100->99 takes much longer than 99->98.
I took the advice of someone in this thread and fully discharged the battery and then fully charged it.
It did take a while though, 6-7 hours from <1% to 100%. Using a computer USB port for charging.
Is charging faster with the provided power USB adapter? Or with wireless charging?

Yes and yes, if you use an apropiate AC Adaptor. Pc is usually charging at 500 mA and an Ac Adaptor up to 2 Amps. So you charge 4 times quicker in theory.

very strange after that its completely fine its like the battery needs calibration. Any one else got this?
me too
Same here. Last a very long time, but the first 7% drops in 15 minutes.
glad its not just mine
I have been seeing the same thing.
Same here...
I think It's due to the charging cycle. Once fully charged it appears to stop charging and I have seen the battery level drop by a few percent before the charge is topped up. This is to preserve battery life. It therefore depends when you remove the watch as to how quick the first few percent drops

So I updated my phone tonight and after it used 30% in an hour or so. All I was doing was using FB on it. Prior I played PAD for 15 minutes and it hardly used 5%. I've wiped cache, cleared app cache, and now I'm working on a full discharge from 100%. The battery is brand new and it was getting better life prior to the upgrade. So much for 3x better battery I guess?
After clearing caches I left it idle ofer night. It used 13% for 20 minutes of screen time. and then it used 3% idle over the 5 hours I slept. Still seems a bit high on usage for screen time but idle is great.
So I discharged it completely and now its losing power fast again. The battery was 100% unplugged it and turned it on and its 97%. So I turned it back off and checked it and its also showing 97%. Charge it back to 100%, turn it on, its on 100% but loses 1% in a second. Plugged it in while onand it took like 3 minutes to charge that last 1%/ No idea why. The battery is brand new and got 2 or 3 days on idle before, now it reports 20 hours. what happened to that 3x better battery? What else can I do to sync the battery properly? I also noticed 100% is not 100% until the phone tells me battery is charged.
Again this battery is brand new and my life with 5.1.1 was pretty good.
I've been having poor battery calibrations in EPH7, though my battery is still what came with the phone.
There are days I can get to about 5? left before the phone dies, and there are days it dies at 15?..
Already tried charging all the way till full while the phone was off, still the same. It's random, but I just generally expect the phone to turn off as I come close to 15?.

That sounds like a bad battery. I can get my phone to drain down to 0% before it dies, but the battery usage can be erratic.
After some testingm the first 5% (95-100%) does down fast but after that it can go a pretty good while. Not sure why. I left the screen on with max brightness, turned on NFC/wifi/bluetooth and just left tons of apps running and it took 4-5 hours to get the battery down to 20%. the life is in fact great just not properly synced. No root makes it more of a pain to calibrate.
So I charged the battery offline and it got to 100%. I switched it on and it shows 97%. What the hell has marshmallow done to my note?
last post. If I charge the phone formt he OS it reaches 100% seemingly properly and doesn't discharge quickly. Not sure what marshmallow screwed up.
I had the same issue with my battery draining quickly after the upgrade. I backed up all of my data and then performed a master rest of the phone and then went into recovery and cleared cache as well. Once it booted back up I reloaded all of my apps and reconfigured all my accounts and my battery acts normal once again. It was a pain in the ass to do all of that but it did work for me so hopefully it works for you too.
Guys m notificing serious idle drains like
I just charged my phone to 100% usd for few sec n then i kept my phone idel for an hour m battery was 92% hell no ..
Also same day at night battery was 88% i close data wifi n all n in morning it was 72%
Whats this something is draining my battery
Battery drain from 100% to 90%
I got this phone last month and yes it's happening here too. When I unplug the charger after 100%, it drops down to 95% in 10 minutes, then to 90 within a few more minutes.
After that it works fine. I've noticed the same 10% drain happening even if I don't charge it fully. Even if I charge 70%, it goes to 60% within half an hour.

I second this, been really frustrated about my battery from last update; been waiting for Pie patiently, hope that improves things and kicks in development.
