Happens often.. Just changed my battery round and it's gone from 100% to 98% straight away without really doing anything

Should I do a reset? And if I do will it return to all the apps being where they are for example?

I noticed that too. I have factory reset twice since December and it still does it.

I am Aquaman!

Mine does that sometimes. My galaxy S4 does it and my original note did it too. I think you just have to accept rogue battery days with an android phone. I don't mind as I have a spare battery that I carry around with me. On the whole though I am pleased with my note's battery life. I easily get a whole day with medium usage and 12 hours with heavy usage. That's enough for me, particularly when I know I have a spare that I can pop in.

[dc52ltr]

Yep,mine too but stays at that level for quite a while before dropping again.

Thats normal. Nothing to worry about. When I take my Note3 off the charger at 100% and do nothing with it, I will loose approx 3% or 4% during the course of a day. The overall battery life of my Note3 is the best so far from all of my previous devices except for my Blackberry 8330 which in comparision doesn't do as many things with a quater of the screen size. I have excellent battery life with my Note3 (JellyBean OS)

This is the norm for any battery it will slow down after the initial drop.

[K.J]

Yep, mines also drops almost immediately as well

[FBA]

Mine does the same thing - in fact, I have two and they both do it.

[vpblaze]

It is normal. Here is a question now, when ever it happens to you, have you left your phone plugged in for a pro longed period?
I have noticed with mine, if I unplug it right after it has reached 100% and has completed charging that it will stay at a 100% and drain normally.
But say if I have it plugged in over night, 3+ hours, it will drain through the first 5 percent in a matter of minutes.
I believe it has to do with the charging of the battery, how after it has fully charged it will drain it a bit to keep the charge cycle going or something. Instead of constantly pushing the charge after 100%....
If any of that makes some sense... I am not a tech Wizz...

It's been doing that since the Galaxy S3.

[CrashPush]

Same here too. It will stay on 98% for a while before discharging even further.

To update the OP I was having two minor problems since upgrading to Kitkat and decided to do a factory reset. 24 hours after the reset I want to report that after unplugging my Note 3 the battery did float on 100% for at least one hour or so before dropping to 99%. The reset did help as well as correct a few other issues. I would say go for it and try it if you haven't already.

When doing a reset and you click backup do all your apps and settings stay as they are now? Or do you lose info and apps etc?

Well sometimes like last night I put my phone on charge at 11pm and then take it off charge about 5am when I wake up for work

[CrashPush]

I was finally able to get a screenshot of my Note 3 battery still showing 100% at almost 44 minutes after being unplugged from the charger. I wasn't really using it much but just to show that this Note 3 is not discharging 2-3% straight away. This was after charging it overnight.

All I did was a factory reset around two days after updating to KitKat. I didn't back anything up because the phone was still new and there wasn't anything for me to backup.

[ThatGuyLurkin]

I'm gonna say yes. No matter what phone I used, the battery percent always dropped from 100% to 95%-98% after about a minute of use. From there it becomes solid.


Never mattered if I was on WiFi or not. I can be at 100%, leave the house and walk 2 blocks then check my phone and I will be at 98% either way.

This is a function of how batteries charge. When your phone reaches 100%, it stops charging and enters a sort of maintenance cycle to keep the battery from overheating (there is special circuitry in the phone and charger that work together to do this). Phones did not use to have this ability, which is why it was bad to charge your battery to full or overnight 5 or 7 years ago. Anyway, in this maintenance cycle, your phone reaches 100% chargered, then is allowed to discharge 2-3% then charges back up that 2-3%. This keeps the battery from overheating and enables us to leave our phones pulgged in overnight without wearing out our batteries. When your phone is in this cycle and plugged in, it always displays 100%. However, once you unplug your phone, it exits this cycle (since it is no longer charging) and displays the true battery percent. Every modern cellphone (smart or not). laptop, camera, etc. does this exact same thing. Completely normal. No need to reset. No need to be worried. You are just unplugging your phone when it happens to be at the bottom of the charge/discharge cycle.

The bare bones of this was explained to me recently.

@jdevenberg - This is an excellently written post. Thank you.
I hope the OP can now sleep better at night.

That WAS indeed the case with OS's prior to KitKat, but since I upgraded to Kitty Kat, I've noticed that it's far more linear now when coming down from 100%. It will stay at 100% for a long time if I don't touch the phone, and once it starts to drop from 100%, it will maintain a seemingly linear rate of discharge. With Jelly Bean, it would drop to 99% within minutes, so I think they may have changed the battery calibration algorithm in Kitty Kat. That said, I noted that Kitty Kat seems to have a slightly better battery life as well!

1st up I have a GN2
2nd up is this from the GN2 forum where a poster said how he solved battery drain using *#0228# when charged to 100%
It drops mine went to 91%
charged to 100%
repeat & went to 94%
charged then went to 96
again then went to 98
now charged to 100% but this time it dropped to 98 as I was doing the reset start (I unplugged charger as I was want to press the start)
It then dropped to 96
I am now in drain to conk out as it is at 25 now
will then charge to 100 and repeat the reset
This is all about recalibrating the battery which is what the process does
I noticed, or thought I did, good battery on way down
Tad over 24 hours on battery only 3.5 hours Screen time now at 23%
This is all to address any perceived excess battery Useage
I think this should address that
But back to OP is that I noticed the immediate 2% drop that it had never done before straight after unplug
Mefinks that when I go to zero then recharge and reset it will go back to no drop

My Note 3 does this as well, and so does my note 2. Actually my note 2 has the zero lemon battery and dropped to 97% in about 10min idle, took another 24 hrs to drop to 90%

This may be a good way to 're-train' the battery. I have been messing mine up in the last week with too many top ups in the same cycle.
However I have on good authority - ish that draining the battery to zero regularly (I know you are not saying this) is not the way to go. 10 - 15% minimum, keeping between 30 - 80% when possible is also good, and it's healthy to top up from 50% as the battery is cooler and it counts as a half cycle in the battery's life.
I haven't measured or regularly noticed the 100 - 98% drop, but I'm happy to accept @FBA's post that this built in behaviour as offered by @jdevenberg has now been changed in Kitkat.

OKey Dokely
so an update from my post # 20
drained till it conked
Took over a couple of hours just to get to 20% to 25%,
so let go overnight
In the am
repeated & it dropped to 91 again
next was 94 or 97
either way when I did hit 97 and redid it went to 95
So
left on to 100 unplug then drop back to 95
But
kept on charge & when unplug noticed 96 then 97
So 20 min charge crept it to 100 after unplug
say 10-11 hours later @ 91
Now 87 looking & writing this
So the 2% drop gone
and
my beautiful battery life is back
@ Madd54
Yip I agree with not draining
this was the 1st time
I treat my phone & wallet as essential go bags
got money got coms go all good
