Battery at 40% -> Phone shuts down

Hi, my cousin's arc is acting weird. It doesn't happen all the time so it is hard for me know what is exactly wrong.
1) When the battery was at 40%, the phone shuts down. This happened once when I was playing with it and I thought maybe I mistaken 4% for 40.
Then a few days later.
2) My cousin noticed the battery was at 40%, he left the phone in his pocket and it shuts down. So now I think last time when I was playing with it, it wasn't a mistake.
Then when the phone is pluged in, it will be low on battery e.g. 4 percent. He doesn't use the phone a lot so it should last a day or two before it need to be charged again from fully charged. But the phone just shut down at 40percent today.
So now it is hard for me to know what is wrong with it. Is it due to battery being defected? Problem with the phone itself? Or might be some apps that caused the problem?
It is running on 2.3.3 Rogers firmware. Stock, not rooted etc. He had the phone for a week and it happened 2-3 times already.
Thanks.

You could try repairing it via SEUS but you will lose all data. Make a back up.

It could be that the phone has stored incorrect limits for the battery - a factory reset should solve this.
However, it seems more likely to me that the battery is faulty.

Thanks for these suggestions. I have searched the forum quite a bit last night and there were a few others looked like the problem I am having. So going to try out those methods first. Then the suggestions in this thread.

Has he tried running the phone flat, then take out the battery and charge it with the phone off till completion. Mine used to shutdown anytime after 20% ; after doing this it never has again. Shot in the dark ... worth the effort.

Any update??

Was the issue resolved? What all things did you try?

Nope, the best I got is 20% then to 1% then shutdown. It is in repair centre now.
I have tried repairing, reflashing, battery widget etc, everything I can find on xda and it didn't work.

Updates
It came back from the repair center and did not get repaired, it was phone being sent only. It still had the problem.
Then sent it again (good thing it is just 20 mins drive on highway) and left the phone and battery there.
Now got phone back, battery is replaced (since I think it was battery being faulty). Now it is at 29% percent and looking good.
I will update this thread if I got more. I am leaving this thread here so others who have this problem and tried all the suggested methods on xda and failed, it means that your battery is faulty!

[Q] Battery or Phone Problem? is making me crazy

Almost every week i have this problem with the phone acting a bit weird. First the phone start slowing down or kind of frizzing, next i turn the phone off...and on again. Suddenly my battery goes from 50's charge to 7% and the phone message said i need to charge the battery. I would turn off the phone again...take the battery out for few 10 seconds or more, put it back and restart the phone? now the meter says i have about 25% charge...i plug it to the charger and wait until is 100% and then seems to work fine for another week until the same thing happen again! Now im on FD16 but this problem has been occurring since i bought the phone 6 months ago on stock, so i think is not flashing new modems or kernels. a bad battery ? Does anybody have any idea how troubleshoot this a little further or has experimented this phone behavior. Or should go back to stock and send this baby to Sprint to try to get a replacement?
I just got to the point that i cant deal with this anymore since i dont know when it is going to happen and may not have a charger at hand!
Please i need some suggestions !

Anybody that can help ???

I have the same issue, is not the battery i tried a few batts and still reboots, im gonna wait for the official ics update to see if is just a bug or a deffective phone.

The battery percentage always decreases dramatically everytime you reboot. Android just doesnt read correctly after rebooting.

The only time my battery would drastically drop after a reboot was when I rooted my phone wrong and it would reboot about 10 times a day and when it did I would lose a good 50% of the battery. Now if I reboot I lose 1-2% even if I flash a new rom. On to this guys issue I would say if it has been doing it since you bought it, it is likely a hardware issue with the phone. My old Evo used to do that. I just ended up selling it because I wasnt sure if it was a problem with the phone or just the fact that, that phone was slow as **** anyway!

Extreme Battery Drain

I never had that much of a problem with the battery on my Desire Z. Okay, I had to charge it sometime during the day when I was browsing the web or playing for a few hours but then, that was expected.
Forward last week, where I decided to try Mimicry rom (I'm not pointing any fingers there, keep reading). Everything was going smooth except one thing, the battery was draining at least.. twice as fast as usual. I'm speaking deplugging at 7 AM, dead at 12:30 PM. And that's with practically no usage. At this point, I've tried rebooting, and, oddly, it wouldn't do the same thing as usual (not opening or opening briefly to the loading screen then closing). No, it would boot to the launcher, show me that I had 2% left. It's usually at those points that I've been able to take a screenshot.
Then, a few moments ago, if I kept rebooting. It would be back at say 36%, but kept hard dying (no "Android is shutting down" or stuff like that, just BAM, black screen) every 5 minutes.
Thinking that Mimicry would be the culprit, I went over there and asked the question, but, oddly enough, nothing in the rom could produce this effect. Weird. He was kind enough to give me some tips to try to see if it would make any difference. I've tried them.. Several time with the battery stat reset, deactivate the Google Backup in case it was in a loop. I've reflashed the rom, downgraded to the earlier version, updated to the latest. No use.
So at that point, Andromadus Beta 5 was out and decided to go back at Andromadus. At first, no problem but finally, it came back. So the culprit is not the rom, or maybe yes, I don't actually know. Today was the day I could use it the longest but.. It's unbearable. Also, I've looked into 4EXT at the battery indicator and it seems to be ****ed up too. I tried to force drain the battery with continuous permission fixing and the battery would drain from 3% to 0% in under 2 minutes, but would stay at 0% for a while.
So, what do? New battery because this one is bricked? New phone, because at the price of the battery... Or is there a way where I don't have to take my wallet out?
Thanks in advance.

Here are some screenshot I took
EDIT
Seems like no screenshot shows up on there. here's an imgur album
imgur .com/a/j9seu#0

Reupload those screenshots nothing is showing, I'd suggest trying a new battery then if that doesn't work get a replacement device.

New photo upload, to see if it finally works.

Mimicy uses Andromadus source so they could share a piece of code which could falsely report battery information. I suggest, mainly as a test, take a nandroid backup. Then plug the phone in and let it charge until you get the green LED. Leave it plugged in for an extra hour or two just to make sure that your battery is at 100 percent. Then flash the Cyanogenmod ROM then reset the battery stats. Try using Cyanogenmod for a while and see if the phone is still doing the same thing. If it is, then it could be the battery. Also if you know someone with a G2, you can always swap batteries and see if the same issue happens. If it does maybe switch to a non-ICS ROM and if that doesn't work, your phone maybe going bonkers.

i think its kinda bricked, or you could buy a portable phone charger. that could help

hi there..same problem with me too..exactly..my battery couldn't last for more than 4 hours with minimum usage...have u solved it?

battery issue

OK so I've been having this weird issue with my battery for the past couple of days. My screen has been cracked and unable to work for about a year and I finally had the means to get it repaired. Got it back. Fully charged my phone. And for some reason. Everytime my battery hits about 53%. My phone will reboot and when it finishes booting up again. I only have 3% of battery left over. Any ideas as to what is happening would be greatly appreciated. Thanks in advance.

Here's a screen shot of what happened

It could be that your battery is dying on you.. My phone did a similar thing where it reached a certain percentage (started @ 100% and went down to ~70%) and would then go into a bootloop. I suggest buying a new battery and seeing if that solves your problem.

(SOLVED) Pixel 2 XL charging stuck at 99% all of a sudden

My 2 XL is only a month old. There is no complain about charging before. It was normal. Hit 100% everytime. Until several days ago, I woke up in the morning and my phone does stuck at 99% with charging rapidly status. I've tried to drain the battery and fully charge, try to flash factory image, but the problem still exist. The phone does charge normally to 90%, then getting slow and more slow when hit 95%, it takes very long time to get to 99, then it stuck for hours. I'm using app called AccuBattery, just want to monitor the charge speed. And there it is, the phone stop the charging at 99%, charging speed shows -1 , so basically the phone cut the power input when hitting 99% although the status still not fully charged. Until I rebooted the phone then it will hit 100%.
So what happened to my phone? I'm using original charger from the box. Is it software or hardware issue? Thank you
The first image is when stucked on 99% and the charge speed show -1. After that I rebooted the phone then charge speed increasing, not -1 anymore at 99%. The second image is when the phone says fully charged at 100% and charge speed back to -1, which is normal if the phone already fully charged.

Solved - see my post below

What's the battery health at?

The battery health is excellent, I didn't have any complain about battery life. Easily get 6++ SOT, full day usage.

What is it at though? But on all my previous rmas, I had sometimes great issues in from charging past 98%.. I would have to turn it off for it to register that it's actually charged to 100% and more than likely it would drop to 99 as soon as I unplugged it.

So you got replacement?
I can't asked for RMA. Pixel didn't sold in my country. I bought from local seller that handcarry the unit into my country.

Yeah I got a replacement at the time but not for that sole reason so I don't know if it would work but I don't think it's that much of an issue if you are still getting 6+h sot

Yeah, I'm planning to do that. I'm just uncomfortable with my phone acting weird, it supposed to hit 100% everytime normally like before. And a little afraid that this issue would make any affect in the future, broken battery or worse. If there's an explanation how this is happened and it's safe, then I might not make any complain anymore.

I had the same issue with my Oct 18 2 XL.
Download Accubattery and "calibrate" your battery.
It removes a file (.bin or something) that resets the batter charge percentage.
I really think the 99% thing is harmless, but if it bugs you (I get it) Accubattery will remove the file that resets it.
Good luck!

I currently using AccuBattery as shown on my post attachment and I didn't found any "calibrate" menu inside the app.
I've done so many methods, like drain the battery to 0% and charge it or re-flash factory image but seems none worked. So I search on the internet about delete the .bin file under root/data folder, but I didn't found any folder called data on /root (currently running android 10). I'm stucked.
So I'm thinking how if pull the battery out and put it back maybe it will reset something, but it seems impossible to do with myself. Until I found a method to hard reboot the phone with press power button + vol down for maybe 10sec. My phone was 75% at that time, after hard reboot my battery increased to 78%. Then I tried to charge the phone and voila, hit 100% normally, didn't need to unplug and replug to hit 100% anymore. It's been 3 days my phone is act normal again. Hope it will lasts forever.
So my conclusion is, seems the hard reboot method somehow force cut the power from the battery to the phone just like we pull out battery then put it back and maybe it's reset something maybe like batterystats or anything. Idk. But I'm glad nothing happened and it was just software error.

When you download Accubattery, open it, it automatically 'calibrates' your battery (see pic)

Oh, I just realized that. Thank you. But I think it didn't work for me. Nvm, my phone is normal now :laugh:

I had somewhat of the same issue with my phone too. Would sit around 98% then after taking it off the charger overnight, my battery would drop like a rock to around 85%. No idea if I was just imagining things but I don't remember that much battery life wasted away like that overnight when not in use at all.
I also sent mine in for RMA last Thursday and get it back later on today so hopefully the issue will be resolved.

I have also been experiencing the same issue since upgrading to Pie last year. Once it returned to normal for 1 month only and then went back to 98% charging issue until today

I would assume broken battery. Never experienced drain so much like that when not in use. My phone normally about 1-2% drop overnight (always on display off). It's great you got replacement, but check twice for screen, 2 XL known for defective screen.

Yeah I am content with the RMA replacement it's just fine, no issues thus far. Just annoying the update breaks charging sound file and lockscreen lock/unlock sounds. But I eventually got those issues fixed too.
