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] Sleep of Death (Solved)

Greetings,
The other day woke up to my Tab 3 10.1 absolutely dead. I tried plugging it into the charger, but nothing happened. After hours of research I decided I would tape something to the power button for 24 hours to try and deplete the battery all the way. I then let it sit on the charger for about 2 hours and there was still no response from the tablet.
Device Info
Samsung Galaxy Tab 3 10.1 GT-P5210
Recovery: CWM 6.0.2.8
Rom: Grievous 3 [01/17/2014]
Can someone please provide some insight on the issue?
EDIT:
I tried absolutely EVERYTHING mentioned for SOD issues with no luck. I filed an RMA with Samsung, but my Tab is rooted and figured they would demand a couple hundred $$ more to fix it. Well I just got done taking out the battery and guess what? IT LIVES!!! The battery is back in it now and am working on moving over to another rom...

Edit: Solved

I work for samsung tech support, and these tab 3 7's have been dropping like flies. When they get to the service center, they do exactly what you did- pull the battery and reconnect, then they box it up and send it back.

You know, the guy I was speaking to to get my RMA had said something similar. That they were getting a lot of the 7" with a SOD issue, but not as common on the 10.1. I just couldn't bring myself to send in my rooted tab so that's when I decided I would try pulling the battery out to kill all power. I wish he would have been allowed to tell me that techs just take out the battery, would have saved me the anxiety of not really knowing if it would work.

Can you do a DIY on 'HOW TO' remove and replace the battery for other users with the same problem?
Thanks for sharing your story.

Great! Thank you

Apparently if you hold pwr+volDOWN for 30 seconds EXACTLY, it simulates a battery pull. Let me know if this works for you please. ~Fake

I tried that.... my Tab was locked up bad...

Worked for me
Just adding my experience with what I thought was SOD.
My T210 was on it's charger overnight and this morning was non-responsive.
After trying every button combination without success I put it back on the charger. Still no indication of life. No battery image, nothing.
So after finding this thread and the video link, I popped the tablet apart and disconnected then reconnected the battery, and reassembled.
STILL nothing! I then thought it may be fully discharged so I put it back on the charger. Nothing again!
I then took the charger and tablet back to my desk and found the charger-to-cable connection wasn't pushed in completely. After fixing and reconnecting the tablet it is now charging and showing the normal battery icon on the display. After a few minutes charging it turned on with no problems.
The battery was fully discharged. I think the battery fully discharged overnight while on the half-connected charger.
So it may have been SOD or it may have been a badly connected charger problem. My advice is to check everything (especially basic stuff) twice.

New Moto 360 Only Charges When Powered Off

Weird defect. Anyone else have this problem?
Edit: as of now it won't charge at all
Edit 2: After a lot of fiddling around, it decided to charge. Working great except for a single dead pixel Got to exchange it on the 9th or whenever they get their shipment in.

Mine charges while powered on.

Mine charges while on and off. What I did notice, is when I was initially setting it up it went up to 32% and while on charger it started loosing charge. I have no idea why this happened but assumed a service was running in the background. Ever since the initial setup, on or not the watch gains charge. Seemed to take about 2 hrs from near empty to full while the display was on showing time.

As of now it wont charge at all. This is driving me insane. I got it to 9% somehow but I have no idea, and Best Buy won't have any to replace it with.

Do you have the cable that came with it plugged into the cradle? I started using my cell cable into the cradle and my battery percentage was going down instead of up.

My local Best Buy said of the two they had today the first sold wouldn't charge. I saw another post on reddit claiming theirs wouldn't turn on, could also be related to a charging issue.

This is a ****ing pathetic launch. There is literally no stock anywhere and of the few that are sold a handful have defects. This is simply disgraceful.

Here's what happend with mine.
First time I powered it on it said to download the wear app..so I did that. Then, it proceeded to connect and pair with my phone. It started to download something, (wear update?) and at about the half way point it said charge your device, shutting down. So it shut down. I put it in the cradle and it initially had 23% charge. 5 minutes later it had 18%. Not knowing what was going on, I turned it back on and was met by a spinner that said just a minute... for about 15 minutes. So I turned it back off.
After another reboot I went into the menu and selected reset device. After this it began to charge.. all the way to 100%. I turned it back on and it re-downloaded what it had to and applied the update successfully after about 3 or 4 restarts and 10 minutes. Now all seems well.
Edit.. By well I mean working. It's been merely 3 hours and with almost no use I'm down 40%. FML

yeah, i think people in their rush to use it haven't charged them fully. i plan to charge mine fully before using it.

This was definitely my issue. The problem is the vagueness of the instructions. It basically says turn it on, download the app.. Show off (until it dies).

I had the same problem with it saying charge your battery. I put it on the charger and left. Came back, it installed an update, rebooted a couple times and then was good. I've been playing with it heavy for a few hours and it's at 69%.

So, I got mine to charge and everything. So far I LOVE IT. I made a post on working apps that I've tested over in the Themes and Apps subforum. Basically, I put it on the Qi Charger I have for my Nexus 5 DIRECTLY in the center and it ended up charging then stopping again. Then, this time, I put it on the charger provided, and it worked to 100%... Very strange but I plan on exchanging it anyway as there is a single dead pixel I can see.

Same issue... Got the watch. Turned it on in the car and it started the update without promoting me to do it and now it is in the same dead cycle I've seen others post about. it will sit on the charger for hours and only be a few percent and when u power it on it tries to update and goes from 10% to 0 in less than a min or two. I just did another reset and put it on the cradle. The only feedback I have that something is happening is the watch is pretty hot. My gear live and Galaxy Gear 1 had an icon that showed charging status when the phone was off. Also they charged quickly, we're always cold and had great battery life. I can't imagine Moto not testing these devices long enough to figure that it should not try to apply an update until the battery was at a certain level or plugged in. I wish when these reviewers do features on the engineers of these devices, like have been recently done instead of ass kissing these guys would at least do some calls g out on their process. It'll like when Apple came out with the IPhone 4 and showed all these unbelievable signal testing facilities and they couldn't figure out when you held the phone normally on your left hand that the signal would drop to zero. It literally took me 2 minutes to figure out that one...

I highly advise you sink a hour charge into the watch first at least. most of these new batteries are like a lithium ion / lipo hybrid. they have a low voltage cutoff so the battery cells don't get damaged and go kaboom. Noone knows how long these sat or what charge was in them, how cold and so on during shipping. I would say people are running them low enough moto is triggering low volt cutoff.the update may have even changed the voltage values they accept as tolerable. and when you power it up this tricks it into a fail mode. ost smart chargers see the low volt and refuse the to charge for risk of a damaged cell. this sounds a lot like moto 360's issues.

When mine hit 80% on the charge, the update downloaded, watch rebooted, and the charge message started appearing.

my galaxy tab3 is charging super slow

hello everyone.
My galaxy tab3 8'' was charging super slow (from 0% to 100% more than 5 hours) so i send it for repairs to Samsung service (it's 2 months old so i was covered by the warranty) it came back yesterday followed by the technician's report saying that he replaced the battery the charger and the screen (no idea why he replaced the screen too since it was fine). i charged my tabled later that day and i noticed that the charging problem wasn't fixed, it still takes ages to charge . what do i do?

Maybe you need a Custom Kernel
Take a look at Tab 3 8.0 Development Section.
Good luck.

[q] sudden death note 8

HELLO ALL
Please help me ..i GOT MY NOTE 8 DIED two days ago ,,i was using it normally i left it on the chair and woke up in morning found it such a dead piece of plastic,,,
tried to turn on,,no response,,tried hold power on and volume up
power on and hold all keys,,nothing work at all
it even does not recharge,,and does not connect to PC
i have too much important data as well as i love this device
PLEASE HELp ME URGENTLY

Unplug the battery for a minute. If you can't get to charge after that, get a replacement battery. There was a batch of bad batteries that Samsung had issues with in the Note tablets. At one time they would replace the unit. Though, you would loose your data in the exchange.

thanks for your reply but
the battery is not replaceable in note 8.0

It is, and you can get them online. Many with battery issues have noted to pull the power ... in fact there is a thread all about this that I am surprised you missed.

i went to samsung service center and they told me u need a motherboard,,and am so frustrated
where are XDA DEVELPOERS to help me solve this issue,,,,
any trick i can try to get it back to life ??
PLEASE HELP

all service centers said the same (need a motherboard) but why the note can TOTALLY DIE without any previously notice,???

There is a YouTube video showing how to get to the battery. I did take off the back cover of my note 8 and disconnected my battery for a minute then reconnected it to solve charging and time keeping issues I had with my Note 8.
