Weird Batt issue, then fixed itself!

Samsung Focus (wife has one too) I use it a decent amount during the day, check emails all the time, surf some, read kindle books, BT on my 35m commute home, etc. Batt lasted all day just fine all day. I always charge it overnight with the charger.
10 days ago or so, got up to unplug it from the charger, and for some reason it would not start, it was dead showing the batt symbol. I moved the charger to another plug (first one is fine though) and let it charge all day, and it finally took a charge. But for the following week, it would be dead by Lunch, every day. I googled "Samsung Focus Battery Problem" and found a few peeps on various sites with the same issue. Tried several things to attempt to fix it. (removing battery, plugging phone into charger, re-inserting battery) Nothing helped. I'd have to connect it to my work PC to give it enough charge for the drive home.
Stopped by ATT shop, they agreed to send me a new Batt for free. I was not warm and fuzzy thinking that alone would help, but it was worth a try (it arrived today) before actually replacing the device.
So after a week of frustration, it was on the charger late Saturday and all of Sunday. Monday (yesterday) I take it too work, and its all fine again? By evening it still had 3/4 Battery. Same today. Weird or what!
I'll save the new battery for some future day, but for now the Phone is fine. Weirdness indeed, was it the phone, or OS or what?
Anyone else run into this?

Disabled feedback
I've noticed notible battery drain especially overnight and during the day with the feedback function in the settings section enabled. When it is disabled, my phones battery last forever...ok so it last till the next day at least, I am a heavy user. The funny thing is that when you soft reset the device the feedback automatically enables itself. I don't know if this might explain your situation. It seems like from time to time my battery seems to drain fast and other days it seems like i use the phone for the whole day and barely make a dent in battery life.

Nope, all settings have stayed the same, it does check my 4 email accounts at various times, I use Cellular Data all day, Wifi only at night (home). Habits all the same. It was a wierd bug, as confirmed by others during my search. Just dang happy it fixed itself.

I ran into a similar situation for the first time today. I've had my Samsung Focus for about five months. The phone gets light usage and has been handled carefully (carrying case etc).
Last night I noticed battery level was being reported as about 20% remaining. Normally I would have expected the charge to be at about 50%. I put the unit on charge overnight and this morning the battery meter was still showing about 20% remaining - essentially no change. I moved the charger to another outlet and tried to charge the phone a couple different times. I cycled the phone on and off and tried starting the charging process with the phone off. I also tried charging from a PC USB port. Nothing worked. In fact I started getting a message that the battery power was low, turn off phone to avoid losing data etc.
I checked on the Net for known issues with Samsung Focus battery problems. There were two suggestions that seemed worth trying; one suggestion was to sync with Zune, the other was to reseat the battery. I tried syncing with Zune first. That didn't seem to make any difference. Then I reseated the battery after I had powered the phone off. When I restarted the phone, the battery meter showed the battery as fully charged.
I don't know if it's a hardware, firmware or software issue, but there were enough reported incidences to lead me to believe that there is some sort of battery related issue associated with the Samsung Focus. If I had to venture a guess, I'd guess that it might be a problem with the battery contact design.

[Q] Battery Dying

Hi I have a Nexus 7 and up to lately have been really pleased with it. All of a sudden the battery has been dying on me at around 30%. Screen just goes black with no warning and completely shuts down. When I put it on charge and start it up again it shows battery at 0% but recharging from say 30%!!! I have done a factory reset at 95% charged and still no different. Tried using a different charger and this time the battery kept peaking showing 50% when started using it and then went up to 54%, this happened twice and then died at 40%; Shows up very clearly on the battery graph too. I have noticed a lot of people have been complaining about this since the recent update 4.1.2. Have called carphonewarehouse and they say to send it back but if it is an update that is causing the problem surely a replacement will have the same problem. I will also have to send it back to UK as live in France and purchased in UK so seems a lot of hassle if going to have the same problem again. Would be very grateful for any help and advice. Thanks in advance;

Power related issue

I'm finding that sometimes when I plug in the tablet to charge even if they battery is almost full, as soon as I plug it in it will think the battery is at 0% and start shutting down.
When I power it on and look at the battery stats it shows that the battery went to zero and then goes back up to were it was before the shutdown.
Also another issue is that the battery status will say its not charging even though it's not plugged in and the level never goes down even after a reboot. I find to fix it I need to go into a custom recovery and reset the battery stats for it to return to normal for a few hours.
I'm running on the stock image.
Its annoying, but I'm hoping that the next update will fix this.

Can't say I've ever experienced such an issue, on any device. If your looking for a fix, perhaps reflashing the factory image completely might help (I don't understand the battery stats file too much, but I would think a reflash would probably replace that file, and fix the problem).

I thought I was the only one with these problems. Never had these issues on my Galaxy Nexus. Now on the N10 I have the first problem you mentioned + battery % not moving until I reboot the unit (Random). Very annoying...I called Google Play support and after doing some test told me that they'll send my a new unit.
Note: I've flashed the Google image and I still had the issue (seems less frequent)...Sometimes I can have the % correctly refreshed and sometimes it stops after a few minutes.
I've attached screenshots of the problems...(1st image) Long straight lines were when I was actually using the device!! Cut in graph = reboot
Second image: both problems, check out the spike a 0%!! when plugging usb cable

I have the same issue and my replacement is on it's way.

So I called support and I'm getting a replacement device.

I've been searching everywhere, thanks to this thread now I know I'm not the only one having these exact same issues. Looks like I'll be making a call to Google Support

Probably a software issue to be addressed in a later update.

Are these issues still present on the replacement devices?

So far not happened on my replacement device. Went from 70% to almost 10%. Still testing. Also wakeup time is normal. I think it was hardware related.
EDIT: on my 3rd day and this new device always correctly reports battery life. Definitely hardware.

I'm having the exact same issue with battery % not updating at random times and then sometimes the n10 claims 0% battery after recharging overnight and promptly turns itself off. Did the replacement unit fix this for you?

Yes my replacement unit is perfect. On my fourth day now and no issues whatsoever. My first unit was doing it day 1.

I got my replacement unit 4 days ago and the problem is definitely gone! On my first device it also happened since day one.

My Nexus 10 just started doing this after a reboot last night, I guess I'll have to ring support and get a replacement.
I'm running a custom kernel, recovery and unlocked bootloader. Do I have to flash back to complete stock before I send it in?
Cheers guys

I'm not sure if I have this issue, but my N10 is definitely acting strange.. I put it in my bag this morning on 42% charge and when I took it out in the afternoon it was dead (I thought I might have hit it to something and damaged it), but when I plugged it in it started to charge after a few minutes from 0%. Then it rebooted after like 5 minutes without me touching it and it's charging for now. The battery stats don't show a drop to 0%, the graph ends at 42..
I've had this device for around 3 months now and never encountered this issue before, so I'm not sure if it's really a hardware issue, but I'd be quite disappointed if I had to get a replacement as this one is a really good one in terms of the other common issues (bleed, throttling, creak).

[Q] Battery problem - suddenly turn off

It’s been a while that I have a strange problem with my batteries. I used two different batteries, both original, charged with the original charger support for the second battery (sell in bundle with it).
It’s almost two months that my phone started to turn off suddenly when the battery level is around the 30%, with both of them. I thought it was a problem related to the batteries age, since I’m using them in the last 2 years.
I tried anyway to contain the problem. As first option, I did a battery calibration. To do this I needed to discharge all the juice from batteries. I noticed that the residual 30% that I saw before the phone turn off wasn’t a fake value: it was real.
When I turn on the phone in recovery, the battery level is exactly the same that I have when phone turn off itself. Moreover, to reach 0% of battery level I have to wait a while and I can keep the screen on (always in recovery) for about an hour. On the other hand, if I try to restart the system, the phone turns off just after the Samsung logo of starts a non-sense bootloop.
Considering what I ‘ve written above, I think that my problem it’s not an hardware problem.
Does anyone have similar problems? Do you have any suggestion to avoid it?
As supplementary information, I’m running the last Italian official firmware with TWRP and root.

same problem
I am note 4 owner for 1 week now
it is an used phone (rebuy)
original rom 6.0.1 newest updates
on delivery the batterie was on 0%
first time use it shutdown at 35%
without warning
now after multiple charging and calibration
it shutdown at 20%
in 2 days I will get new Batterie and I will check again.
maybe batterie is old

Similar issue in the last week or so with my N4. Original replacement battery, 10 month old, turning off with no warning on reaching between 20-15 % charge mostly if i try to use the camera. I've put back the original battery and seems fine for now. Ordered another battery, Anker this time, just in case

Yeah Samsung carefully crafted these batteries so that they won't work any more after six months of usage of something. Mine is nine months old, the phone itself, brand new, and mine turns off at various battery percentages, sometimes its 5, sometimes its 12, I have stopped caring and I charge whenever I get a chance.

Conclusion Faulty Battery Only
Any battery poerventage is mainly determined with help of its volatage. As battery discharges this voltage also reduces. As battery grow older, we is gradually unable to handle the load as it used to when new one. Also battery life is determined by its charging and discharging cycles. It was all about basic. Now talking about note 4, being andriod fone and requres lot of battery so we usually charge it for 2 times depending on use.
The same problem was faced by me as well for note 4 at 30% it used to reboot all of sudden and thereafter bool loop (in actuality it is not as battery deoesnt handle load and it again starts to boot so no home screen). Replaced the battery with original one a month ago and now issue till date and fone lasts below 5 to 10% with 4G on and doing browsing.
So it is concluded for sure that battery problem.

Weird thing last night i experienced the same issue! And my phone is only 8 month old, i think this issue it's related to Samsung updates.. my phone did shut down in exactly 30% and started to go in bootloop i removed the battery and put it back and still the same i was about to factory reset my device for god sake ? luckily i did connect my charger before i factory reset my phone i gave it one last try and it did boot normally.
So i am not really sure what is going on.. no more updates for me unless it's a major changes

Happened to me too. I think it's the battery, I tried several batteries, some cause sudden power off some doesn't.

I'm upping my thread after two months to say that I solved my battery problem changing them. I bought a new one from Samsung official store and now I'm able to do more than 4 hours of SOT and charge phone once in two days (Red Dragon Note 7 porting). Before to change, I was not able to use any Sammy ROMs, due to several reboots and disgraceful battery life.
I don't know if the battery is the guilty for everyone's problems, but I really suggest to try to change it. Just, be sure to buy an original one, because there are a lot of genuine clones, especially on e-commerce sites.
For what regards the problem itself, I think that the cause could be the use of a different charger (Samsung, but for an earphone), coupled with the extra battery kit. Unfortunately the original adaptive fast charger stopped to work a month after the phone arrived and I didn't bother about it.
So, I also suggest to use only the original cables to charge the device.
I hope that this testimony will help someone with the same problem and, at same time, I also hope that Samsung will consider to use again removable batteries to give people the opportunity to do what I did.

Faulty

First of all -please excuse the thread's title, but I encountered an issue where I couldn't input content in the "title" box unless I refreshed the page and started typing before it loaded the page fully (tried on both Chrome and Firefox - VERY odd).
Recently I've encountered issues with the phone (N910F) getting really hot and shutting down the phone. I was in The Philippines at the time and the daily temp was around 34 degrees so I thought this may have had something to do with it. One battery in particular, whenever I used the camera it would shut the phone down. I stopped using that battery and then eventually the other 2 have been doing the same - they are all after market batteries bought from Amazon from Anker and Rav power and within a year old. But then it would get worse and the phone would just randomly shut down - it seemed to make no difference if it was at 90% or 30, it would just die. I'd often have to do a battery pull and hold down the power button just to get it to fire back up again. Over the last 2 weeks it's gone form a few times a day, to multiple times an hour! I even tried to limit the load by changing the governor to "powersave" and that initially seemed to help matters.
I figured it could be one of three things going wrong - a software related issue, a hardware issue with the phone or failing batteries. I installed [ROM][N910G/F][ODEX]* DQL1 * Multi-CSC, De-Bloat stock, Fast&Light[CUSTOM] and it was a while till anything happened but then once again - it shut down. So I don't see it being ROM related, I'd only added a couple of basic apps too, so I cant see it being a rogue app.
My last N910F had the EMMC failure and I recall that it would regularly freeze or lag heavily then crash and bootloop, but normally my phone just shuts down. I'm hoping that this means it's most likely battery issues, but it seems strange that all 4 batteries would fail within a 5 month period, especially as they were all on rotation. I even took to only charging them (in a Samsung external charging cradle) on an evening when the temperature was cooler. I've contacted both manufacturers but I know that Anker dont have any replacement batteries anymore, so I'm hoping Rav power will replace that faulty battery (that one started to swell a few days ago.
So, what do you fine fellows think is the likely issue that I'm encountering? I don't want to throw good money after bad and buy more batteries if it's likely that it's a phone issue, but I also don't want to get rid of the phone if I can get it working again.....
(I'd been running the Resurrection Remix Rom on Nougat for about 10 months. I went traveling 8 months ago so I didn't update the ROM as I it wasn't super stable at that point and I was happy how it was working - if it's not broke, dont fix it! But after a while I started to have issues and one of the batteries began to swell. I got rid of that one and switched between the other 3)
