I noticed while charging I get that huge half transparent battery notification indicating the battery level a lot, and inconsistently.
( the notification you see when you plug in the charger )
Tbh I'm not sure if this happened before the jb update. I did see it before but never tried to time it or check percentage levels and I don't remember how close they were to each other.
I got it when it hit 21%, 63% and then another at 68% then the next one there were a few others in there but these notifications were not based on 'round' numbers for battery level (eg 10, 25, 50%, etc). And they sometimes appeared within a few minutes of each other
I tried wiggling the cord around to see if it was a bad connection but I can't trigger it myself. I'm wondering if the battery is broken
Is this normal?
I'm 100% charged and still getting these popups while plugged in.

At first I thought my charger was broken so I also played around with it a bit. But prior to the JB update I didn't have any of these random battery notifications popping up, so Im pretty sure its just JB
Same here. I notice it since JB update.
Same here. I wonder if what's happening is that the tablet switches to battery once it's full, drains it a bit, switches back to charger and alerts when the battery gets full again.
On ICS I was seeing the battery oscillate between about 97% and 100% while on the charger.
[UPDATE: And it's *not* happening at the moment using a different (also Asus) charger...]

Lately my battery has been acting really weird. The percentage has been very off and it has been random with the numbers. I started playing a game at 23% battery and after about a little over a half hour, it was at 21% but I knew that wasn't correct because about 5 minutes later the phone died completely. For the past few days it's been giving me problems with charging as well. When I charged it, it would charge slow and then shoot up all of a sudden and when the charge wasn't done according to the percentage, the battery notification light to tell me the phone is done charging came on but my percentage was at like 75% It's driving me nuts and I don't know what to do! I read that a battery calibration is unnecessary and all you have to do is charge the battery fully and it resets the calibration but I did that and it's still giving me problems.
Mines seems to be working correctly after my latest update , have you posted in the CM10 Thread ... Have you tried doing a fresh flash and see if that fixes the issue ?
Hi everyone
My problem is.. my DS started to charge slowly.
Now it doesn't really charge slowly, If I check the voltage, I will get like 4220mv but as soon as it reaches that, the charging graph just goes flat.
If say I have charged it to 70% and it started going slow. i switch it off, place on the charger, and the lamp goes green. I turn it on, and it is showing 100%.
I have tried calibrations, diffirent kernels, wiping, factory resets e.t.c.
Another thing is that if I will run a v6 battery calibrator,it will show that actually I should have a 100% charge although a phone is showing only 70%.
So the summary: Phone charges normally when off (when recovery monitors charging), showing the correct voltage when on... But showing the wrong percentage if on charge.
Also sometimes if the battery is like 14% left. And I turn the phone off and then on again, it will show 22% bearing the same voltage as when it was 14%.
Question: Is there any way to tweak the battery indicator so it would show % values same as the v6 calibrator does it or is it a hardware fault, if yes, which part of it ?
This happens to me on my older (original) battery, but not my new one. I bought the second battery when this problem started happening. So, I think it's just a symptom of an old battery.
By the way, if you leave it on charge long enough, it will eventually jump up to 100%.
Other than this weird behaviour, it has no real impact on anything.

Thought so, mines been acting similarly lately, but strangely enough it seems to be getting better
I think I found out..
I actually purchased a new battery recently, because my old one was jumping like crazy and started discharging in a few hours..
This new battery I bought from a mobile repair shop.
It is a cheap chinese battery with no name, anyhow I just took it out to take a look at it...
And guess what, it sais 1200mah..
Can the phone be confused because of that ?
After updating to KatshMallow #26 I noticed my dock battery was never charging above 92%. I plugged the dock in alone overnight and the next morning it only shwed 87%. So I connect the tablet and ran it down until it shut off. Prior to shutting down the dock battery indicator never changed from 92%. I also didn't see any indication that the tablet was drawing from the dock battery. I plugged in the dock with the tablet attached and once I saw the green light on the tablet I powered it up. Dock battery = 87%, Tablet battery 100%. I left it plugged in with the tablet attached overnight and nothing changed. Same indications the next morning. Dock never moves from 87% no matter what I do. I installed Dual Battery widget and it only shows one battery. ???
Not sure what happened, and I don't think the update has anything to do with the issue. The dock battery has probably been going south for a while but I didn't notice it until I updated to #26. I have searched numerous threads looking for comparable issues but nothing matches. Even so I tried some of the different apps suggested with no luck. It is puzzling that Dual Battery Widget only shows 1 battery when the Asus indicators show 2.
I have found a replacement battery for $29.00 but before I spend the loot and risk trashing my dock I would like to be certain that it truly is a bad battery and not some flukey software issue that I can fix. Also, all other features on the dock work fine.
Any suggestions?
UPDATE: After leaving the tablet and dock combo unplugged for most of the morning, the orange power light on the dock began to flash. Once I plugged it in, it immediately went solid orange. My understanding is that the light flashes when the battery level gets below 10%. So is it working properly except the screen indicator is lying to me?
I bought my phone new when the Galaxy S6 first came out and have not rooted it.
For while now my battery life has been bad but consistent, or I would say acceptable given what is running in the background. With normal usage, including connecting to a bluetooth watch, LTE, and location services on, my phone battery would drop from around 100% starting at 7am to around 70% by noon. On weekends when I'm just at home and have it on Wifi instead and no bluetooth, it takes until around 6pm to drain to 70%. These numbers have been consistent, give or take 5% for over a year.
The problem started recently when I received an OS update. I can't remember if I was already on Android 7.0 before this update and it was just a minor update for something else, or if this updated me to 7.0 from 6.x
The first week after the update the battery was great. With no change in the way I use my phone I was able to go the entire day without recharging. By noon I was still at 85-90% and by around 7pm it showed 60-70%. So I was able to go the entire day without recharging for almost 2 weeks after the update.
The problem started 3 days ago when suddenly the battery is draining like crazy, and it seems like there's something weird with the battery indicator and the way it's charging. Again, nothing has changed in the way I use my phone.
Now, when I use it, the battery will go down by 1% every minute. And even when I don't use it, it will be down to 70% by 8am and 20% by noon. The stranger thing is when I try to charge it.
Before, with normal use, it will take around 1 hour to charge my every night. Also, the indicator showing how much time is remaining is pretty accurate as well. Now, when I charge it, it seems to take a lot longer. The time indicator will sometimes fluctuate. It may show a realistic time like 45mins remaining, then change to 10mins, then back to 45mins. Also, the times seem to be incorrect. For example, before if I'm at 85% it might take another 15-20mins to reach 100%. Now, it will be at 85%, say it will take 40mins, but after 40mins it's still only showing 90%.
I tried restarting my phone normally, and resetting it by pressing the the vol down and power buttons. I also tried other power saving methods like forcing apps to sleep when I'm not using them. But for some reason, the battery is still draining like crazy.
At this point, given what is going on when I charge the battery, I'm wondering if the real problem is the OS update screwed up the way the phone is reading the battery's power and not that the battery is actually being drained. Maybe the battery in fact is still at 70% by noon even though it says 20%.
Sorry for the long post, I just wanted to be as detailed as possible given that this seems to be different from some of the other battery related problems I've read about on the forums.
Any help or insight will be appreciated.
replace the internal battery
Hey fourm, sorry for the long read but if anyone is technically savvy with batteries or voltages/electrical components please read! this might not be specific to a Fold but any device may suffer from what my device is suffering from.
I have recently had issues with my Galaxy Fold Z2 and it unexpectedly dropping to 0% charge, the first time this happened yesterday i was in an application and was switching from the larger display into the smaller one, upon closing the display the phone shut down and i wasn't able to get anylife out of the phone except a vibration when holding the power button, but nothing on the screen. I had about 35% battery at the time but all of a sudden it was at 0, after putting it on the charger it spring back into life. Today however i experienced an even worse problem... My battery was around 55% and i was connecting my phone to my cars bluetooth and importing contacts to the cars console, suddenly the battery went from 55% down to 9% instantly! i was shocked and took a screenshot of the battery graph showing its gradual decline from 100% to 55% but not to 9% to highlight the sudden drop, the battery status on the top of the notification bar was showing 9% all of a sudden but the graph wasnt just to actually see the drop! after that drop in battery it only took about a 30 seconds for that 9% of battery to jump down to 1% again in an instant fashion, following this only a few seconds later it shut down.I was thinking it could just be a dodgy battery for whatever reason but after trying to charge my phone after this sudden crash from 55%-9%-Flat i was unable to charge it up. The phone would signify that it was charging but not giving me a percentage, it would show the charging animation (the animation you get when phone is off and charging) but would only last for around 3-5 seconds before shutting off again and showing the charging icon again, and then shutting off again and rinse and repeat on a loop without charging but attempting too and resetting every few seconds! So for about an hour i couldnt get it to boot/charger properly and i almost gave up, but i decided to try a different charger, i was using the 25w supplied charger but i switched to a 15w older one and the phone ran the charge animation again however this time it identified the battery was charged at 55% rather that it not showing any charge level and resetting and trying again as it did before, this time it went right to 55% and from here the phone booted up and is working normally again!
Im really not sure whats wrong, im starting a process to send the phone back but i really wish to know whats wrong with my device! if anyone has any clue to this strange behaviour please let me know!
