Incorrect Battery Life Meter - General Questions and Answers

I have a Samsung Galaxy Note 4 running 5.1.1 and have been experiencing incorrect battery life measurement. My battery meter will say I have anywhere from 15-35% battery life left, then the phone will shut off and restart, when it comes back on the battery meter will now register 0-1%. Any reasons why I'm experiencing this issue? And are there any known fixes?

Buy a new battery.

I am experiencing a similar issue with my older note 4.
I have a year old black note 4 and a newly purchase white note 4 and I noticed something strange.
The black reported 50% battery remaining, the white reported 80% remaining.
I switched them off, switched the batteries and turned them back on.
The white then reported 40% battery and the black reported 91% battery.
Seems like the black is always reporting around 10% to 15% more than it supposed to and when it reaches around 20% it suddenly drops to around 5% and there is a rapid drain until it shuts down.
Wondering if there is a way to fix the internal gauge or something....

Strange Battery issues

Am having 2 issues with my battery. I have an Anker 7200 mah extended battery currently. {I have also noticed these issues with previous batteries I have used}. I charge my battery to 100% and then when I check the battery screen in settings several hours later, it will show for example that I have been on battery for 4 hrs when in fact it has been 5 or 6 hours. The second problem I am seeing is on the bottom portion of the battery screen it will only show % for screen, device idle, cell standby and sometimes, voice calls. It will not show usage % for other things like email, tapatalk, games, etc. Pls see attached for example. In the screenshot it shows I have been on battery for 2 days and 0 hrs when it have been at least 2 days and 5 hrs. And bottom part of screen only shows screen, device idle, cell standby and voice calls percentages. I've let my battery drain until it was almost completely dead and I've calibrated my battery but still having same problems.
Was wondering if anyone else has come across these issues and what was done to fix?
Thanks!

Weird battery life; battery not charging fully

Hello, this is how my battery life looks like.
So, battery, when it charges, goes up smoothly up to about 50 percentage mark. Then, the rate of charge slows dramatically, followed by a huge surge at the end. As soon as I unplugged my phone, however, the battery drops significantly, and I end up losing battery even as the battery is charged.
Any idea what has happened? I see no significant wake lock (I have no idea what the application says it's active), signal is high and sync is turned off. Is it a hardware issue? Corrupted battery stat?
I am running CM 11 Milstone 12, and the battery is a ZeroLemon extended battery.

Sounds like the battery or possibly the charging port is going bad. Those are really the only two I can think of

Don't you have shutdown issues?

As probably many of you already know, there is a shutdown bug mostly affecting Nexus 6p but also other devices as well.
I've been using my Nexus 5 for 3 years until a week ago I got the Nexus 6p, and I had not noticed this issue. However, after having the shutdown a couple of times with the Nexus 6p, I decided to test with the Nexus 5, and I'm finding quite easy to reproduce the problem, what make me wonder why I hadn't read such complains about Nexus 5 before.
Just getting to 15% and spam the camera a little (around 7 photos), and it dies (battery drop 15 to 0). Tested with two Nexus 5.
How old are the batteries in the Nexus 5 phones you used for the test?
You aren't replicating the bug. The camera really does suck down battery life like you wouldn't believe. You are most likely genuinely draining the battery 15%. I've been on a Nougat ROM for a couple of months now and haven't had any sudden battery power off or anything of that nature. I can bring it down to 1% everytime before it dies.
Are you doing this on stock ROM or custom ROMs? What Android version?
everything stock, 6.0.1.
your theory would be ok if the battery remained on 0%. But after turn it on again, some times is indeed at 0%, but other times it's at 15%.
Also, according to that logic, if the device is at 100% and I take 10 photos, my battery should drain to 85%, right?...
It's not a theory. Batteries don't always drain at a linear rate. For example, going from 100% to 85% could take 1 hrs. While going from 15% to 0% could take only 20 mins. This will be made worse by an old or dying battery. When a battery is under load, you have what is called "battery sag." Let's say the battery is at 3.7v. When under heavy load, the voltage could drop to 3.5v or lower, aka: battery sag. When the load is removed, the voltage will jump back up, though not as high as it started because while under that load, it also drained some juice from the battery.
You are probably experiencing heavy battery sag while at 15%, enough to drop the battery voltage low enough for the phone to power off. The heavy load is removed (camera is no longer on), and voila, now the battery is no longer "dead." My first Android phone (Tmobile G1) wouldn't even allow the camera to open if the battery was at 15% or lower. Most likely because the heavy load and subsequent battery sag would cause the phone to power off almost immediately.

Mi 11 lite (miui 12.5.1) battery drain while idle

Hi all,
My phone drained 14 percent battery yesterday while idle for 9 hours. The interesting thing is when i add the mAh usages that i see in battery and performance tab it only adds up to 6 percent battery usage. ( i calculated and confirmed with time that 40 mah is aproximately 1% battery)
Also this morning i am seeing an unusual drain as well while the screen is on, it drained 5% but it should have draned only 3% because it says it drained 138 mAh.
Does anyone have any idea about this problem?
This also happened 2 weeks ago and the only thing common both days were, i charged my phone slower (charged using usb on the car) instead of using fast charging.
I also leave the screen shots that shows the battery usage.
Put the phone into Airplane mode when idle: this may save some battery.

yes of course but the battery drain I explained sometimes happens I actually think its a battery indicator bug. Because it shouldn't be draining this much battery because it doesn't show any unusual drain on battery information screen contradicting the percentage lost (14% battery was drained but according to battery information screen it should be 6%)

Question Phone is off, but battery is still draining

Is anyone experiencing a battery drain even though your S22 Ultra is switched off? I'm experiencing 4% drain every hour. 32% when every night when I sleep with my phone turned off.
I turn on power saving and extra dim using the bixby routine for the period that I'm in bed sleeping. It loses 1-2% ph
If you don't mind, can you try turning off your phone for the night and see how much battery percentage it loses? Mine went from 32% to flat 0% by morning. I had not realised this until recently. I tested in the morning by turning off my phone for an hour, it went from 60 to 54%. That's like 6% in an hour. But if I keep it on standby , it'll be 1% down in an hour. It's the turning off that is causing problems.
I know some laptops will drain battery power after shut down, but phone?
Exy or Snap?
Try checking in details with a battery monitoring app (e.g. GSam) to see what is/ are the culprit(s).
Also take a look at here for some useful tips.
It's strange that a lot of battery drain when phone is completly off.
In my opinion it's short circuit or battery is fault.
If phone is normal on are you see too battery drain?
When phone is switched off battery shouldn' experience any drain, or at least any noticeable drain in a short period.
Remember, when you bought your phone it came with battery half charged, and that was probably months after it was assembled and sealed in its package..
You should take your phone to a service or replace it, if possible
maybe somewhere on the PCB there is a short circuit. I ran into the same problem when using Xiaomi Mix 3 11 months ago.
