[Q] Battery drops to 95% once charged fully? - One (M7) Q&A, Help & Troubleshooting

My problem is that after charging to 100%, the battery drops to 95% after the course of about 10 minutes after unplugging the charger.
After reaching 95% the percentage would 'normalize' and discharging would occur on a more regular basis.
I have been experiencing this problem for the last 2 weeks or so.
It started happening suddenly, can't remember doing anything out of the ordinary to cause it to happen.
I tried letting it discharge to 1% then charge fully but the problem still occurs.
Even tried this app but still the problem exists.
Tried about 3 different ROMs also but still a no go.
Any advice about what can be done cause its driving me up a wall?

It's a known base bug and the only way I can think to 'fix' it is to charge your phone while it's off. I turn mine off when it's nearly fully charged.
Seriously nothing to worry about.
It's been reported many times now if you had used search

Ok thanks. Will try charging with the phone off.
I am curious however how this started happening without me doing anything unusual.
I mean prior to this happening it was discharging normal.

It use to bug me too but I've had the same or better battery life in the end so it's all good.
Started happening when 4.3 base was introduced

Does this happen when you charge your phone overnight?

Well I never charge my phone overnight. I always unplug it when I go to sleep.
This occurs through regular charging

Try discharging completely, then charging completely while the phone is off, then start using it normally without intermittent charging. See how that goes.

Hmm will try that but I've read that discharging comepletly can be dangerous.

You shouldn't do it always, but once or twice a month isn't harmful.

What I find is I leave my phone and plugged in for at the very least 10 minutes after it reaches 100% and only then does it discharge normally.
Asides from that my phone also drops to 95%

Didn't realise this problem was so prevalent.
Becoming less bothered about it now.
But will do a full drain and charge with it off on the weekend.

I have the same issue and I usually do what "Jonny68" does and it works
I've read somewhere that it is intended like this by hTC to protect the battery

Tried the charging while off option, didn't let it discharge to 0% however but that seems to have worked as I finished charging about an hour ago and it is still at 100%.
Thanks everyone for their contribution.

Screen flickerig on low battery despite battery replacement

Hi,
Hey i am using my note for a year now, and my phones battery got swelled, with some discussion on xda i was adviced to replace my battery which i did with another original samsungs battery. Now this new battery is charging and discharging fine, and is giving me an on screen time of 5 hours with constant messaging and music and some browsing, the issue that i am having is of battery indication and screen flickering.
First the screen flickering issue, whenever i am below 20 % my screen starts to flicker and it keeps on flickering till the phone dies, sometimes even at 15%. Then when i tried to charge it, it charges from 0.
At times when i partially charge my phone, say i am on 50% and then when i unplug my phone at 60%, it then shows 75% indication but then the flickering starts at 30% and phone dies at 26%.
The battery is giving average time so i think its not a battery issue or maybe it is.
But then i mostly found it a battery indication issue, i read multiple threads and even wiped my battery status. but the issue is the same.
may be give it a few charging cycles.. charge it from 0 to 100 with phone off.. till it says completely charged.. then check the performance..
Maybe you bought a faulty battery!?! did you bought the orignal samsung battery?

Well yes its from samsungs outlet, dated and stamped.. otherwise the battery indicators and every other stat is good. On full charge it has 4.320 V. Discharging equally to 2.8 V. But indications is not going according to the drain and flickering at low %.

I am having a similar issue where my screen will flicker for a minute and then immediately turn off and charge from 0%. I was wondering if it could be a kernel issue as my battery is the stock battery and has never had problems before (I am on XXLSC). To me it looks like the battery is not getting enough power (hence the flickering) and then turns off. Sometimes if I turn off my phone as soon as it starts to flicker and I wait 10-15 minutes I can turn it back on no problem, other times it will just die. I have tried clearing battery stats, and was going to try my spare battery but apparently that swelled in storage.
Good luck in figuring it out! I will report back if I find anything new.

4320volt, interesting, I think its faulty, its off about 120 volts. If it depletes at a higher voltage, it looks like something is astray with the meter/level indication or battery

Sorry for the confusion it actually was 4320 mV or 4.320 v when full charged.
Let me post some screen shots. The overall on screen time is around 5 hours. So the battery is giving a good timming.

Phone shuts down around 15%

Hi guys,
Since a few days my phone powers off when de battery is around 15%. And when i charge the phone again it starts charging at 15%. I repaired the software but that didnt help. Any ideas how to fix this? I am not rooted and im not planning to do that with this phone.

Just charge the device to full capacity and don't restart it. This behaviour is normal.
Each restart or time spent in recovery, breaks remaining capacity estimation.
Full charge repairs it again.

Out of curiosity, is this a software problem, a hardware problem, or a Sony is really bad at making phones problem? My first Xperia TL by them bricked itself less than a week after purchase, and now I am having this same problem with my new device ever since the update to Jellybean. I have this device through AT&T, could it be their fault? My problems with my Galaxy Note were their fault so I wouldn't be surprised.
You may notice a pattern, if its a feature of every you phone you have its a feature of the phones.
This issue has been discussed repeatedly, its all to do with the way the phone calculates the charge and its not really an accurate picture of the power in your phone. Thats why some people ave noticed their percentage going up whilst not on charge.
I suggest you just use your phone as normal for a week, (I.e no flashing etc) and let it go through several full charge, this always settles the battery stats out.
Also, the new bateries we have prefer to be on charge, so whenever posoble leave it plugges in and NEVER let it discharge, the new batteries dont like that

Try calibrate the battery Go on Google Play and search for "Battery Calibration"
Mine was doing that too. You SHOULD read this post just in case http://forum.xda-developers.com/showthread.php?t=2355862
How I calibrate my battery:
I made sure my phone is unable to be turned on again by making sure it has no battery left. Charge it without turning it on for 3 hours.

Battery issue :S

I have searched this but could only find one other person having this issue and no one really knew. But when I charge my htc one to 100% take charger out and then put it back in it shows 98% all of a sudden.
So I let it charge more and take it out and in again still does same thing. Done it repeatedly too. Anyone else having this issue ? Or a solution? It is like it thinks it's charged fully put it hasn't. And it's annoying. Thanks

Try the battery calibration app from the playstore, that might fix the percentage drops.
this is normal behavior, my one does that too and gets perfect battery life. this happens because the phone charges to 80-90% very quickly then trickle charges (on and off) for the remainder of the capacity. this is to prolong the battery lifespan and is a healthy way to charge the phone. my iphone 5 did the same thing.

Battery Stuck at 100%

My phone has been showing 100% battery for a couple hours while listening to music and using bluetooth. I was messing around with ROMs/Firmware earlier today but went back to what I had by flashing the previous firmware and restoring backup. Anyway, at one point I saw it go from 70% to 90% during a twrp backup while charging. I know that's not true since I'm using a slow charging QI receiver. Any thoughts on how I can get it to recalibrate?
Edit: Funny I click post and check my phone again and it's 99%. I'm sure that's not right but at least it's moving!
I say just let it discharge fully and then charge it up to 100% without stopping it. Hopefully that'll recalibrate it; I believe the batterystats file no longer exists anymore.

I turned it off and let it charge for 10-15 minutes and now I'm at 74%. That's more like what I thought I'd be at. Thanks for the suggestion!

Note 8 battery discharges insanely fast on every other charge

I have been want to replace my Note 8 for a while, but decided not to because it would work well every other charge cycle. On days when it's working well, it's decharging at around .8% per hour on idle. But every other time I fully charge it, it'll do this weird thing where it drains at 3%+ per hour on idle. I don't know what to do or what the problem is. There isn't a difference in app usage. Does the fact that I completely discharged the battery on the first day have an affect on how it is now?
I use mine heavily at work, music, messaging, browsing, calls and I get around 12-14hrs out of a charge.

That's not my problem. My problem is that it will work really well, but after I charge it, it'll go to complete crap. I'm not sure what triggers this.
Have you tried factory resetting the phone?

Yes, I've done this like three times. It will work well sometimes until I charge it. Then it will randomly have completely terrible idle time. I think the battery drain outside of idle is actually not bad either, but something makes it drain a lot for some reason. I've noticed it usually happens after I charge my phone.

There isn't a tip someone can give you to fix your obviously defective phone other than to start the warranty process.
This phone costs too much money for me to **** with. If it so much as hiccups, it's going back.

I was just wondering if there was something I was missing that was causing this. It was draining really fast on idle last night, but the fast discharge stopped around the time 60-70%. I charged it this morning and it hasn't even dropped 1% in the last 1 and a half.
OP try not using the fast charge options and see what happens.

I did try both, but it didn't seem to make a difference. I can't seem to figure out what's making it drain so fast. Right now, it's back to normal. But even when it's draining fast on idle, it's battery life will still be good in actual use.

Try slow charging all the time and also remove SD card if you have one. Also, when slow charging , when it hits 100% power off device, then pull charger out and then back in with device still off, it might read 98% then let it charge to 100% again.

I'll try that. I usually let it charge to 100% and then wait another 30 minutes.
But why remove the SD card?
I am also facing this problem of the battery draining too fast, especially when compared to my previous phone, the S8 Plus (and similar usage on both phones).
Battery usage data does not show any rogue app gobbling up the battery. So not sure what is going on here. Perhaps I have got a faulty device...

Just an idea. Using method of elimination [emoji4]
When it reaches 100% remove charging cable and power off device then re insert power cord with device off.
I personally never use fast charging.

Going to Samsung area of Best Buy tomorrow. If they can't fix it, then I'm going to Costco for an exchange.
Got a new phone. It's draining fast too. Is there a way to identify what app is making it drain so fast?
I want to specify that the battery life when actually using it is great. I was watching netflix for over 2 hours and it drained like 15%.
