Battery issues!!

I've been having some strange issues with my Nexus recently...
When the phone gets to around 50% battery (sometimes happens as high as 63%, sometimes as low as 40%) it suddenly shuts off. No "Shutting down" screen or anything, just black screen and dead. Then once it's restarted (after plugging into the charger) it shows that the battery is at 0%!
The charge then jumps up really quickly (from 0-60% in about 20 minutes) and in really odd increments such as 0-8%, then jumps to 15%, 2 minutes later I'll look at the phone and it will be at 38% and then charges more steadily but still quickly to around 60% and then (mostly) normally from then on.
The battery also seems to discharge really unevenly when unplugged, the battery level will sometimes drop down around 10% all of a sudden or it will still be on 97% after charging all night.
Also this morning the battery was discharging while plugged in. I've been using my Galaxy S2 charger since launch as the wire is longer and once I noticed what was happening dug my Nexus 4 charger out of the cupboard and used that which then started charging the battery back up. I've included a screenshot showing this happening, when the graph starts raising was when I swapped to the official charger. The GS2 charged is now charging my Nexus 7 without any issues. The only other place it is charged is from a 12000mAh Powergen battery pack from Amazon. This i also used to charge other devices (Nexus 7, friends phones) without issue.
The phone is completely stock and updated to the latest version, I did replace the screen with an OEM one a few months back as I smashed it so one concern I had was that I may have damaged the battery while dismantling the phone but it has been fine up until a couple of weeks ago when these issues started appearing!
Does anyone have any suggestions or ideas?

I would do a reset

I did a factory reset earlier and the problem is exactly the same.
New battery time? Or does anyone else have any other ideas?
Thanks

Could be a defect . If a factory reset didn't fix it. I would think it's a hardware issue.

Battery/Charging Issues (Nexus 4)

I am having problems with my Nexus 4.
History, replaced screen after phone was knocked out of my hand, probably damaged battery while trying to remove it, but everything worked once it was back together.
Screen broke again, and while working on that, I noticed the battery had swollen so ordered a replacement of eBay.
All back together now, but.
1 Phone does not state "charging" when connected to AC or USB charging, although the battery icon has the lightning bolt in it and the %charge does not drop while messing with the phone.
2 Phone does charge using wireless, but slowly, and status swaps back and forth between charging and not charging and the % will move from e.g. 40% to 35% as it says charging or not charging.
3 USB works for connection to PC.
I charged the new battery overnight, wirelessly. It got to about 90%, so slow charging, but seems to work. Phone is usable, everything seems to work. I connected it to PC and was able to use Nexus Root Toolkit to backup, the reset the phone, no change in charging behavior.
Booting into safe mode made no difference either. So it seems it is not software/firmware/apps that are causing the problem?
I guess next step is to open it up again and remove and remake all connections and check contact posts? Should I order a third battery? Or a new motherboard?
I searched here, but could not find anyone with the same problem.
Any and all help appreciated. Thanks in advance, guys.

Opening and rechecking connections and coating with contact cleaner has made no difference.
Phone typically needs Volume Down and Power button pressed to get it to start, then Power Button to select start option, then seems to run okay.
Battery still not reaching 100% charged, generally 70-80% after a full night off, using wireless (my Nexus 5 charges happily on same charger).
Ordered a cheap battery from China, not really expecting that to be the problem, but no other clues or suggestions for now.

Any update?
My battery is ****e now, lasts 3-4 hours and I need to turn off the phone and charge. It takes 4+ hours to charge when switched on. Charging via the PC you can forget it, it drains the battery if anything!
I'm thinking of buying the battery on eBay and doing my research on how to fix myself.

Phone not switching on and Battery issues
Hi,
I have been facing quick drainage of my Nexus 4 battery since past few months. Recently I had been keeping it on charge almost the whole day, and a full charge would last only 2-3 hours! Further, the charging was taking a lot of time too.
Today, my phone had already switched off due to low battery when I put it on charger. After the white charging icon appeared for a few seconds, the phone wasn't charging at all. I have tried 4 different chargers, but to no avail.
Can someone help me? Is there a guide on how to change the battery?
Any help and urgent help appreciated!
Zany!

It's possible some hardware was damaged when you took apart and put back together your phone. The USB board is a possibility, as is the back cover itself. These parts are pretty inexpensive, if you want to try buying a replacement, but that's just a shot in the dark.

Buy a new battery. Li-ion batteries are only good for a few hundred cycles or so (~500 cycles is the expected lifetime), and the N4 isn't exactly the best in battery life, so you can reach the point where your battery turns to crap within a year or so (or less).
Go to ifixit.com and look at the teardown. All you need to replace the battery is a T5 TORX driver (for the screws at the bottom), something thin and plastic (like a guitar pick or a plastic knife - they do make professional tools for this) to pry the back cover off, a tiny phillips screwdriver (like for eyeglasses) for the battery screws, and something to pry the old battery off of the adhesive holding it in. Double sided cellophane tape works fine for keeping the new battery in. When prying the cover off, go slowly. A little at a time, don't rush or force things. Or you might flex too much and crack the back glass. Don't forget to take out the SIM tray first.

Time for a new battery. See above.

My battery have started to swollen up a bit but not alot (around 1mm or less, but it is noticeable when not in a case, it can wiggle a bit from side to side but not alot at all).
I have already ordered a new battery if it is expanding more, but yet battery life is pretty good in standby but not getting more then 3hours of SOT. but since im mostly using the N4 for email's and texting its not a problem for me to get through a full day.

I'm having the exact same issue but I've never taken the phone apart. In the 20 minutes its been off charger it's dropped 11% screen off in my pocket. It also gets hot and shuts off.

That could be software/ROM related. It sounds like somethings keeping your phone going full blast instead of letting it idle.

Yup, trying going back to full stock (should always be first step if possible), and then you can go from there. If it doesn't happen, than it was a software issue, and if it still does than it is definitely a hardware issue. Best of luck.

With a swollen battery I strongly recommend you stop actively using the device. Swollen batteries can explode and that would not be good at all. I advise you to please not use the device anymore.

Third battery (original, suspect replacement, now China sourced replacement) has been working well, phone back together and preforming as new for the last few months

[Q] Is this an issue of a dead battery?

While charging my Nexus 7 I noticed that the battery was actually draining rather than charging. This is happened in the past as well where I would plug it in overnight and find it at 42%. My Nexus also dropped from 100% to 77% in less than an hour with no use at all.
Recently while charging I went into the bootloader to shut down the Nexus. Now I plug it in and the screen is blank. I have tied a rubber band around the power button so it is constantly being pressed.
Is this a battery issue that can be solved by simply ordering a battery on eBay and changing it? The past behavior of the tablet makes me think it's either a software or battery issue.

i have the exact same thing... n7 is dead as a brick... have tried everything... i also measured the battery and it's on 0.93 v so there is still juice inside...
can't figure why it doesn't work... if u find something plz let me know too

mine done the same thing . But it done so after leaving it for a few weeks not charging. I charged for like 30 minutes . turned it on . It started updating apps. then all at once screen went off. and that was it..
I had square trade warranty as my tab was bought back when 32 gb 2012 version came out. So i sent it in and they fixed it . I have no idea what they done but it has the same serial numbers mac address and so on. So i suspect it was just revived somehow.
I sent email asking exactly what was done to fix it with no reply back.

Don't have a warranty... it the 1st Gen n7 so I called Google and it doesn't have warranty

I'm way past warranty. I've had it a couple of years now.
I bought a battery off of eBay. I'm going to remove the back cover and replace the battery and hopefully that will fix the issue.
Will update with the results or lack of results.

Moto X frozen

Welp had my phone for less than 24 hours and its basically dead. A little backstory, I had the phone down to 4% battery and decided to try the turbo charger out. I had it plugged in for about 20 minutes and came back to a pretty hot phone that was frozen. I unplugged it and it was at 50%. I plugged it into a normal charger and went to sleep. When I woke up the phone was off and still somewhat warm. Since then it turns on fine but freezes after being on for about 5 minutes. Any idea what is going on? I am pretty disappointed; but on the other hand sounds like I got the first lemon.

Looks like a faulty device, better return it and have a peace of mind.

Oh man, that sucks! I have noticed the phone gets extremely warm when charging ...
I guess you are going to have to get on the horn with Motorola support and see what they say. If they can't solve it hopefully they can get you a replacement rather quickly!
Keep us posted!
MOTO X PURE EDITION!

The heat concerns me on these phones. I've got an LG G2. I kept it on kitkat due to their lousy Lollipop upgrade that basically ruined my phone. It charges faster than any phone I've had, does not get hot and has the same size battery. I don't understand why the phone has to get so hot when charging. I hope they don't start having exploding batteries or other hardware failures like the OP is having.

Yeah I used my normal charger because I didn't trust keeping it plugged in over night. After about 10 restarts the phone started back up and was "optimizing apps". Now it's working but does get hot still. After a few talks with moto support I can confidentiality say they are worthless.

I definitely noticed the heat the first time I charged it. I pulled it off the charger this morning and it didn't feel warm at all. Not sure what the deal is.

I had a Nexus 6 for a while and any of these quick charge phones get warm when they are being charged. The quick chargers pump a lot more current into the battery than a standard charger. Electronics can take a lot of heat before they fail.

Has it frozen up on you again? I was going to recommend a factory reset, but I would definitely call Moto and see if they can get you a replacement sent out.
The phone will definitely get hot when charging at times. That's just a byproduct of charging, especially at 25 watts. Nothing to worry about too much, but it should have some smart circuitry that cuts off after a certain temperature or time is reached.

Mine did the same thing! Out of the box everything worked great - for like an hour. After that it's been non stop freezing up and the screen staying off with random vibrations.
I tried factory reset and going into recovery and wiping the cache. Nothing helped.
I had to call Motorola and they refunded my money and emailed a return label to ship it back. I'm going to have to order a new one.

Won't turn on, no lights, but warms up when plugged in.

As the title says, Phone won't turn on. There are no led lights at all. It does get warm after being plugged in for a little. I had jrkruse's hybrid_bra1 stock safetynet samsungpay...... rom on it. It was rooted. Very minimal processes running. I actually had basically everything stopped and greenify on. Phone was around 40% battery. I plugged it into charger, took my dog outside, showered real fast, washed a few dishes, then came back in to room within 15 minutes to my phone being dead and hot. It's never got this hot before even while rooted and plugged in with this rom on it. I have never had it get that hot. Was just formatted the day before and really bare but, that is what happened.
A couple battery apps I had put the batteries remaining life capacity at around 60%. It held a charge poorly. Even for 60% capacity it felt weak, considering how little I did on it lately. I am thinking the battery may have took a crap but unsure because it warms up when it is plugged in. I plan on getting a battery soon since they are inexpensive and replace it to try it out.
Just wondering if anyone here has any experience with this and can offer any advice.
Thank you in advance.
(I looked for a min or two for similar posts but didn't find much. Will gladly take down if someone can point me the way)

You say your battery was already outworn, It may have died. I think you should try with a new battery, Or take it to a technician who can test the phone's hardware to see if there is anything else broken
i've only had one similar case with an s3, which would turn of at random % of battery. But when plugged turned on. I replaced the battery and it worked fine then

I really do hope that is what's wrong. I just ordered a battery. Thanks for the reply. I also got some little tools and battery door adhesive sticker. Wish me luck!
funny story....
The mic in my Nubia Red Magic broke and I sent that back to hong kong for repairs like 20 days ago. Before the Red Magic, I used this galaxy s7 edge my friend gave me. I gave it back when I got the Red Magic and told him to sell it or something. Not much later, decided to buy it back off of him for $200 to give to my mother. She loved it. I had the gs7 edge with me exploring prepaid provider options for my mom when the Red Magic mic broke. So then I decided to borrow the edge from her till my phone got back and few days later I break this one too..
I feel naked without a phone for so long haha

I have the same rom, with charging issues. I don't think its the rom causing it. The s7e are getting old and the batteries are taking a toll with the age. My phone will charge up to 81 at night and stay there. I get better results with wireless charging so i just top my phone off during the day with my wireless charger. There is a code to reset the battery's internal memory, if i find the link on how to do it I will post here for you.

Thanks for reply and alright let me know if you find out. My phone had no problem charging to 100% Its just the 100% on the status bar wasnt 100% of the 3600 capacity from wear. My friend's also does the same thing as yours except his he cant charge more than like 24% haha. He just uses it as a plugged in music player in car.... I am getting battery in the mail tomorrow and will see what I can do.

I have not done it because it requires draining the battery and I never get around to doing that. Hopefully it will help you out. Good luck!

A little late, sorry. lol.
Thanks for suggestion, however, I may have worded my statement incorrectly. I meant to say that My phone would charge to 100% and the status bar displayed it as 100% but, the health and total capacity of the battery in mah was not the maximum 3600 or so due to simple wear and tare. It isn't apparent within any stock android feature however, battery monitoring apps like accubattery gather statistics after several charging sessions and estimate the current mah capacity. Mine was much lower than the default oem stated value of 3600. So my battery could be charged 100% but the 100% is really only 2400 mah lol. It was obvious either way by noticing that after my time using it and the previous owner's bad charging over night habits, that the battery was gradually needing charged more often lol..
I did read about the calibration method before when I was first looking into the battery issues. It seems it is more often done after a new battery is installed.
I screwed up a new battery install at the last second. I had to stop due the tiniest little round metal piece coming off from a very light swipe of my plastic spudger.
It was a very small wire connector piece. Unbelievably irritating. I didn't even finish because I doubt it would work properly. I beleive it is for the rf cable or something not sure. The red one on the left bottom side of the logicboard/motherboard whatever. There are three of them.
I took it apart and put it together a couple times prior to this and in a hurry it popped off and I couldnt find it. I couldnt find out the exact part name online so I could buy one and solder it back on. I did find a site/ supplier that has a plethora of them though. They are tiny coaxial connectors/pins. I didn't look through them all but there are 6,000 some listed under coaxial connectors (RF). https://www.digikey.com/products/en/connectors-interconnects/coaxial-connectors-rf/437?k=coaxial pin
I haven't gotten around to asking samsung or the digikeys support if they could help me find out which it is. They have different sizes and frequency ratings or speeds and such. The phone is packed away until I manage to figure out which pin to buy or if I pull 80$ or so out of my behind and buy a whole new motherboard logic board haha.
