[SOLVED] Incorrect Battery Values

This seems to be quite a common and somewhat obscure at the same time.
Many people have reported installing a new rom or even just powering up their phone and seeing a battery % much different from what they expect. Most often much lower than it should be. Evidently this corrects itself after some time but it's a real problem if your display reads <15% because you really have to plug it in then, even with you know you have 90% battery!
So, here's the solution after testing it under different circumstances over a few days:
Simply boot your phone when it is not plugged in to a power source and battery % will be accurate.​
That simple. Silly LG!
So, if you flash a new rom, unplug the USB cable before you reboot...
Hit 'Thanks' below for the 50 reboots I did to prove this...

hehehe jups allready figured that out on myself tho haha. But indeed that's kinda silly of LG

What about every time I use a custom rom the battery % indicator jumps right down to 90-95% when unplugging from charger ? Do you have a solution for that ?

Try rebooting after you disconnect power.

Sorry to say the same..
Even while charging with the phone shut down, pulling it off the charger and then booting this happens. On my phone I have experienced it on all MCR's.
It's really not a big deal as long as the battery performs as Stock 10b, that build has been stable batterywise on my phone. But staying stock isn't too much fun

Well, every time I charge, whether I reboot/shut down before unplugging or not, my charge always maxes out at 96%.
Annoying and I'd like it sorted if at all possible.
Anyone?..........lol

ye i got that exact same issue i was wondering why that was happening and hoped that a simple reboot would fix it but its a bit more complicated than that i suppose...
also the battery reset in cwm didnt fix the loading till 97% w/e percentage.
when i install the stock rom it allows me to load it till 100% though pretty weird stuff -.-

I had a replacement netbook battery that could only max to 90%. So, over the weekend, I practically drained it to 0% (not a healthy practice for Li-ion batteries but I was desperate). Took out the battery for a while, and then recharged for several hours. Well, it seems to get up to 100% now.
Perhaps you could try using the the phone until it very low on battery before recharging. Maybe the charging process in the phone needs some sort of recalibration. But should not be doing this all the time as it will reduce Li-ion battery longevity.

Let mine totally die last night so it wouldn't even turn on at all. Took out and replaced battery and then charged it overnight and hey-presto, when I unplugged it this morning, it stayed at 100%.
Solved indeed....for me anyway. Feel free to try the same and post your results.

I'll be sure to try your tip man. But not easy drain it completely when I always need the phone :=)

I guys! I've got the same problem.
I think that it could depend on the "full battery popup FIX" that Paul introduced in his roms by the FR8.
So I would like to ask Paul if you can create a patch to remove that fix. Just to try it!
According to me, incorrect battery amount depend on a wrong voltage read error (offset introduced?) by the rom. :blink:
In my case, I have followed many times battery wype procedure without positive issue. The matter leaves only by flashing original roms.
I think that if Paul have written a wrong battery values range (to delete the battery full popup) that can be traduced in an incorrect battery status displays.

It was occurring before Paul introduced that change unfortunately...

After I wrote here, I registered a premium account to Paul's from modaco site and toke a custom fr12 rom without "battery full popup remove patch". Now I'm going to sleep and plugin the 2x to charge. Tomorrow I'll write here if is that the solution...

I'm sure it's occured from fr8 in my case. With stock rom I haven't any battery problem so there is something wrong in fr raleases of course... I hope somebody discovers what is...

Perhaps, but you can not conclude it was introduced by MCR. You logic is wrong there.

Even without "battery full popup fix" it doesn't work good...
Battery level, when unpluged, stay at 100% for 2 minutes afterwards drop down fast until 85% then drain normally...

I'm getting huge battery display problems no matter what I do.
When I took it off the charger this morning, it said I had 100%... thats fair enough. However it stayed at 100% all day, so to "refresh" it this evening I restarted the phone, and low and behold it now says I have 27% left. But again, it's just sticking at that value, even with me now plugging the phone into the wall to charge. It simply says "Charging (27%)" and won't budge, likely until I restart the phone again.
Sometimes it works fine, it seemed to be doing ok last night before I put it on the charger. Any tips/suggestions? Is this something likely to be fixed when the Gingerbread update rolls around?
This is my first real smartphone, and am fairly annoyed as its giving me a fair few problems that I've not had from other electronic devices.

As I stated in another thread, I had the same issue while on MoDaCo Fr12. However, after reverting back to stock, the battery percentage is spot-on and I'm getting up to 48 hours use out of it.
Draw your own conclusions.

That sounds super, but I'm still on stock too. About the only things of note I've done are root and switching to Launcher Pro. Oh, and Clockwork Mod of course. Perhaps a complete reboot is needed, we'll see how it goes.
Saying that - since charging, my phone has been at 90% all evening, until right this moment when it changed to 89%. It's less than I'd expect on this type of phone for 3-4 hours use (or lack thereof, I've barely touched it), but it's a start eh?

Welcome to the world of smartphones my friend. I've had various handsets over the last 4 years from iphone to android and a day and a half out of the battery is about average......at best. ;-)
Sent from my LG-P990 using XDA App

Just to clarify, what I meant in my previous post was that I was expecting to battery to drop a lot more than it did. The fact that it only went down 1% in several hours of use prompted me to think that the battery value was messed up.
As it is, I've not charged my phone in the 36 hours since, and it tells me I have 73% battery left. Perhaps it is performing extremely well after all? If that's the case then I'm more than happy with it, but being the pessimist I'm still expecting the phone to turn off sometime with the battery reporting incorrect values.

with charger in 100% charger out 97% recently

did not have this problem befor flashin jvs but now when im charging it indicates 100% battery and directly when i unplug it it goes down to 97 did not do this before flashin 2.3.5 and I even flashed 2.3.4 now! I managed to get 98 by disconnecting and connecting charger many times. Why?

I have darky's 10.2 Exrtreme or final - can't remember
I have the same problem. But even worse mine sometimes only charges to 60 or 65%. I can get a full charge after several unplugs and re-plug but it takes a while.
The big problem is once it fully charges it seems like the phone stops charging completely and then begins to drain out - should it not maintain the full charge even if left charging at full?
Any help please.
Thanks

I did some more reading. Apparently my problem is a bug with respect to SGS and gingerbread. Once the phone reaches full charge - it stops charging and even though its still plugged in. At this point the phone drains (presumably like normal depending on what you have running in background).
At this point the only fix is to flash back to froyo or I think charging the phone while powered off would work too. Not much of a fix but at least when I wake up in the morning its fully charged.
For others with the same problem as me see this thread:

If anyone else has a better alternative I am all ears.

Battery virtually dropping, hardware or software problem?

Hello,
for months it has been happening that when the battery usually reaches 25% (but not always sometimes even 40ish) the battery indicator drops to 19% and it could either remain stuck at that value until the charge actually drops below 19% and continue the usual drop or it will rapidly drop to lower values in big steps like (19->10->4) in minutes to finally actually automatically power off. The strange thing is that it's all fake! When I power the phone again the % will go back to where it should be before this virtual drop happened and continue its usual drop, it always worked until today when for the first time it continued the "game" non-stop until the battery ended the actual charge (for hours)! You have to consider that i was in a place in the mountains where the gsm coverage was very low/non existent so it could be connected. But it got me worried because it couldn't control it!
Apart from a solution I'm asking also what the reason could be. It could seem like a battery problem but why would the phone actually recognize the actual charge after it powers off and I restart it ? Seems like a software problem (battery driver maybe?). But I wouldn't exclude that it could be the battery maybe when the charge gets low the voltage drops dramatically under stress to a point where the phone thinks its almost empty.
I'm using cm7.2 kang 119 with standard kernel.

Have you tried wiping the battery stats..?

So you say it's done that for a while... obviously it's not possible to pinpoint an app. I guess then you have some funky cruft buildup (say, a lot of rom flashes and some settings getting squiffy) or your battery's dying. I know for sure that the rather excellent Battery Widget Reborn can give a health check on the battery as part of the widget (although I dunno if it's GB compatible). The second solution may be to try a clean wipe. It's drastic, yes, but can clean up any lingering problems if you've been updating for a long time without the occasional wipe. If you haven't...then I dunno.

I'm not trying to be rude. It's just that battery stats are reset after every reboot, so wiping them does nothing. It's also easier to be blunt to get a message across.

S3 Mini restart/switching off by itself problem

Its been almost a year now since I've had this phone. Recently, my phone has been restarting/switching off by itself....once it turns off, it won't turn back on again unless I plug in the charger. If I try holding on to the power button once it happens, the "S3 mini logo" just keeps showing up and switches back off again. I even did a factory reset and still it didn't fix the problem. Even when I try going through my phone (reading messages, going through settings, opening an app), it'll just automatically have the problem again and switch off again. One time I kept my phone on sleep mode for about 5 hours, and after that I just wanted to make a phone call and again it just turned off.. please any help would be appreciated..
in the morning around 7 when I unplug my charger batt is on 100%
10 min of browsing on wifi it goes to 85%.
It holds on 85% from 8-11 AM
Then I turn mobile data on, browse for about 20 sek and it crashes.
Keeps on restarting and batt is on 0%
I connect the charger batt is on 56% in couple minutes, and stays there till 6 PM
Around 6PM I turn wifi on, browse 20sec and it goes down again.
Not turning on until I connect charger.
When I connect charger it is again on 60%.
how to solve it ????

just wanted to make sure if it is a firmware or battery, now i can confirm it and say that it was a battery problem for anyone that has the same problem.

I had the exact same problem and today I put in a brand new battery, I waited for it to drain then I charged and calibrated it when it got to 100%.
After 40min of Internet browsing 25% had drained!
I am waiting for it just to turn off of it's own accord pretty soon.
Update: phone appeared to be okay, although I thought the battery was being used up fairly fast.
Today while charging the phone the battery was at 80% and during a conversation on the phone, it switched off of it's own accord. I then had to power back up the phone.
So I do think there is something up with it.
Any ideas folks?
The phone is really starting to annoy me and because I rooted it I will have to bring it back to stock before I attempt to bring it back to the shop for repair. But that is the last thing I wanted to do.
Cheers

Well after a week now and the phone is still losing juice rapid.
Sometimes it will charge well and I would get half a day or of it. And on other occasions it just shuts down after being left charging all night.
This is after a brand new battery has been installed!

you´re device isn´t rooted, so you can´t use xposed.
lots of apps works in background on stockROM like yours.
So root your device and battery drain will be better.

Then out of the blue two weeks ago the battery went crazy, I bought a battery and it is still not good. If I can't find a solution I will then have to revert the phone to stock before I bring it back to the shop as rooting voids the warranty.

Thanks
Thanks guys
i replaced the battery and now the problem is solved

Just flash the stock firmware and kernel, and see if it solves the problem. If not then you have a dead battery on your hands.

I also have the same problem, it also seems to happen at 30 percent. I'm pretty sure we need to change our battery

Well its the easiest way to see if it is rom/kernel related or if something is wrong with the hardware.

ok thank you. just one more question just to be safe, should i just download the firmware from sammobile and flash via odin in download mode right?
and another fellow here advised me to calibrate my battery to check if its hardware or software. he told me to charge to 100% and delete this file data/ system / and delete BatteryStats.bin use to 0% and then charge 100%. should i do it before going stock or not?

had the same issue a few days back (f2 stock rom and kernel), battery dropped from 17% to 0 within a few seconds.
but this occured only once, the next cycle was ok, so i guess it was a calibration issue!

Easiest to try battery calibration first. If that doesn't work after a couple of cycles then just flash the stock rom from Sammobile using Odin.

ok thank you guys, i guess i just have a ****ty life and very very ****ty luck happens to every phone tablet i buy. FML

There are 3 possible reasons this happens - broken phone, broken battery or software problem.
I think the first one is unlikely so you need to figure out which of the last 2 is.
Make a back up of your current rom and install an official TW software. If this still doesnt fix your problem, its most likely the battery. A new genuine battery is around 20$.
PS - i think that the battery stats bin file is automatically deleted once you fully charge the battery anyway but you can still try it altough i doubt it will fix it.

same problem here

And here.

This is typical of a dead battery. Your best bet is to buy a new one.
Less than a year is short but not unheard of. Overheating (especially when 100% full), deep discharge, very intensive use (especially with quick charging) and manufacturing defects all can kill a battery.

I'm on CM12.1 with this problem. I've tried battery calibration and tried a new battery but its still apparent.
Will be trying a factory reset as my last resort.

This is happening to 2 phones in my household it started after the upgrade to 5.0.1 one note is Tmobile the other sprint....highly doubt we both developed battery problems RIGHT after we both ota upgraded.

Same here at ~13%.
I do always either fast charge or QI charge.

So far I've tried:
- Battery calibration
- Bought new battery
- Factory reset
Still happens!!
Maybe I'll try TW flash or modem change

Weird, I have this exact same problem as the original post. I'm running BOC5 on the 9105. It's a sporadic problem only occurring on occasion

I've been running Lollipop for ages until this problem happened. Frankly, I still prefer Lollipop with this problem.
