Value changes, charge and check again.
Quick tip: If you're charging to 100 stop doing it. If you let your battery drop below 10% stop doing it. If you play on charge stop doing. It'll hit the battery life very slowly.
So i shouldnt charge beyond 100?
I normally charge overnight

Mine had 288.something
Then it deep discharged and now it has 310.something again.
I would not care too much about this value to be honest.
Stop charging overnight. It hurts the battery and reduces cycles. If you don't charge to 100 and leave it you'll get thrice the battery lifetime (should last 800+ cycles).
The values keep flitting, try charging the phone and see if value increases.

Hello all.
I'm on rooted gb (I know,I will update soon) running abyss4.2 kernel and sometimes when I reboot my phone my battery percentage drops STRAIGHT down.

Does anyone know what's causing this?
So, we cause a triple murder before breakfast, start a race war before dinner - that's uh, that's a pretty good day.
Well...I'm pretty sure that restarting your phone uses a good chunk of it's battery seeing as you are stopping everything and then re-opening it basically.
maybe you must calibrate your battery, or try 2-3 full cycle battery charging..sorry just my simple thought
worth the try,tx for the input!
Sometimes after a kernel install the battery stat is incorrectly reflected...a reboot would pick this up but as has been mentioned, give it a couple of full cycles and see if you still have the issue.
Download battery calibration from playstore and do the calibration.

Hi guys,
I charged battery till fully charged yesterday and I went to flash a firmware upgrade which took about 15 minutes in total and thereafter when my phone restarted, it showed me 39%, a huge 61% drop during this process and I checked the battery voltages in fastboot getvar all and using gsam battery app, it still showed me 4.2-4.3V which is usually a full charged battery. Now after charging a while, it suddenly goes back to 100%, any idea is this normal? This is the first time this is happening.
Hope to get some help and advice around here, thanks guys.
Screenshots after charging over an hour:
Just plugged into charger:

After charging over an hour, suddenly it shows up at 100%
You need to re-calibrate your battery. There are a few different ways I've read people doing it. I usually just let it totally drain, then charge it to full again without messing around with it. You may want to search for a proper method.
Lately battery stats won't reset when I unplug my phone from the charger. It is midly annoying.but I wonder if it could be a sign of a more serious issue? Right now my time on battery is showing 44 hours and screen on 9 hours which is obviuosly not true.

Yes, obviously I tried that.LOL
Don't the stats only reset once the phone fully charges to 100% ?
I granted battery stat permissions to a few battery monitor apps and I thought the commands were not going through, but they battery stats did not update until the phone was charged above 90%. I guarantee if you charge your phone to at least 90% or preferably 100%, your stats will update as fragtion said.
I asked this question a few weeks ago to no avail.
To reset the battery stats dial *#9900# ( Snapdragon ) and then select the option Reset Battery stats.
While testing charging on the XZ2 I found out that we use the new Qnovo Charging technology which tries to reduce the usage of a CCCV point but adaptive charging.
Another really strange phenomenon was the maximum Voltage.
4.331V
After checking the disassembly video I saw the battery which stated 4.4V....
Sooo... Time for crowdsourcing!
I need your help guys.
Use this app: https://play.google.com/store/apps/details?id=kr.hwangti.batterylog
BatteryLog, or Ampere, or whichever method you want and take a good look at battery Voltage when you reach around 97-100%
Is the 4.4V on the Battery a fluke? Or do some batteries reach different max Voltage? Let's find out!

Hm. I haven't fully charged the XZ2 yet, but on my LG V20 it also says 4.4V. So I decided to open the back and take out the battery (removable batteries! Such a great thing!) and found Li-Ion Battery 3.85V, and lower down some chinese characters and then 4.40V. No idea what that's supposed to mean... maximum voltage? Anyway, the LG V20 also seems to top out at 4.4V.
The reviews said watt this and watt that so I expected big things
Plugged in seems to take 2 hours, forever, and so I bought a £60 wireless charger, and that is 90 mins to charge only 50%
Why has charging seemingly gone backwards? I know the battery is bigger but still.

It's just how Samsung works. No one understands this behaviour, I mean why does the phone almost costs 1000$ and doesn't even have like 20W/27W charging.
Even Xiaomi and other budget phones have this.
This would arguably be my biggest fault with the S10 tbh. I charged my phone at 16% today and it took 1hr and 40 mins to reach 100%. Its not a deal breaker given the batteries capacity but its not exactly "fast" either. Slightly off topic but it bugs me even more that theres no way to see what % your on or if the phone is even charging without turning on the display! This baffles me! Any other handset and you can easily see what % the charge is at when charging
