I recently let my phone go to 0% battery because i forgot to charge it last night. This is the 1st time this has happened. So i start to charge it & it still doesnt turn on. The LED flashes orange & green on ear grill. any suggestions ?
Pop out the battery and plug it back in a wait 5 minutes. If its still flashing like that (green and orange) that's a charging error. One of two things... bad battery or bad charger. Of course check a different outlet too. Happened to me before with a bad battery... flashed green and orange. Switched batteries and all was good. Good luck!

Thanks. My friends at school has the same phone as me. So i will try his battery. If that works I will sure to thank you
the phone shuts off before the battery can be damaged. just let it charge a while.
so hows the outcome? *curious*

Not always true. The safety circuit on the battery is supposed to prevent over-discharge. But its possible if you drain the battery drain to zero, and the safety circuit does not work properly (doesn't happen often, but it does happen), that the battery will be over-discharged and no longer be able to take a charge. In this case, only a special battery meter/charger with a boost function will bring it back to life.
Slight chance that the following will work: plug the phone into the wall charger (not USB) and leave it overnight. Then try to power on. Otherwise, you may need a new battery.
This is why you shouldn't let your battery drain to zero. I understand if it was an accident (happens to all of us once in a while). But some people let their battery go to zero intentionally, which is not wise.
Guys i figured out what the problem was. Some how the battery touched water & if you take out your battery & look at little white sticker. If that turns red that means it touched watcher & no longer works... Figured that out today because my friend has the same phone as me & tried his battery. So i will be buying a replacement battery ASAP.

My understanding that lithium ion batteries cannot recover if totally dead. Therefore, a battery at 0% is more like 5% and are built that way as a safety measure.

Hmmm... interesting! No good for you but facinating nonetheless, lol! You could try lightly scrubbing the battery contacts with alcohol and old toothbrush and let that baby dry out for a week. I bet it starts working again... it'll will be a nice backup for ya!

I think that is true. But over-discharge means that the battery still has some charge, but too low for it to take a charge from a standard charger. Then, only a battery meter with a boost function will bring it back. The safety circuit is designed to prevent it from going below whatever the "over discharge" threshold is, but its not 100% reliable. I've seen several reports by XDA users for the Desire Z/G2 what have killed their batteries by running them to "zero", and similar reports on past HTC phones I've owned and followed on these forums.
Recently I purchased my first tablet, ofcourse the Nexus 7 32 GB and I am very happy with it.
As soon as I started it, I received the notice that an update was ready to be installed, which I did (4.2).
After that I got another notice to install 4.2.1.
So far so good, everything worked very well....also the normal charging with stock charger and cable.
Then after about 1.5 weeks I noticed that my battery level didn't went down from 100% to xx%, even after playing games for several hours.
I am absolutely sure this wasn't the case before, I did charge well and battery-level went down normally.
So because I couldn't tell if the battery was empty or not (because it kept being on 100%), the Nexus went down ofcourse.
Well, I plugged in the stock charger and cable and started to charge it.
Battery icon (when Nexus is off) nicely went from first quarter (25%) to full (100%) when I unplugged it.
It booted up nicely, but then I noticed that the battery-level showed 0% and kept stating 0%. Even again after playing games for several hours (GTA4 and RR2).
Normally it should decrease in battery-level ofcourse.
So now I'm stuck at battery-level 0%, but strange thing is that the Nexus works fine besides this small problem.
I can charge it, play with it for several hours, reboot, deplete the battery, etc....
Only thing is I can't see the actual battery-level which is very annoying, since I never know when the battery is empty and needs to be recharged.
I searched internet using Google and also here on XDA, but never found a solution.
What I already did was :
1. Reflash stock ROM, using the Nexus Root Toolkit.
2. Flash CM 10.1 with CWM Touch
3. Tried to hold down POWER + VOL UP + VOL DOWN for 30 seconds
4. Tried POWER + VOL UP
Nothing I did worked.
Did someone had this problem before and was able to solve it ?

Hi,
I had this issue too when i purchased my nexus 7.
For solve the probleme I've remove the back of the tablette then unplug and replug the battery.
Don't had any other issue. its realy a nice tablette you have make a good choice.
Sounds like a problem with the fuel gauge chip... Not sure if you can fix it.

That file only stores the data used to fill the battery graph... It has nothing to do with the actual calculation of battery percentage.

Check out this thread, there's people talking of a fix for PA for battery percentage stuck at 100%.. Maybe the same cause as your problem... Look from post #10047 onwards.. Makes me think its probably not a hardware issue at least.

In PA, is definitely a software issue and seems to be caused by paprefs. The issue that is commonly reported with the N7 across all roms is typically caused by the battery connector not being properly seated. Asus QC consistently has fallen short on this connector.
Sent from my Nexus 7 using Tapatalk HD
I have fixed multiple loose battery connectors using clear scotch tape. The problem is that they didnt use any adhesive on the battery for a batch of n7`s. Makes it possible for the battery to slide back and forth at least 5mm. When it does it pulls the internal battery lead right off the mother board connector. Tape the connector tight. Then tape the battery to that side. Do NOT tape over the copper tape. I even made a small strip of foam to place along the far side of the battery to remove the room to slide.
Easy fix for an annoying problem.

I can surely try to open the back and check if the battery cable is seated correctly, but I'm wondering....
If it isn't seated correctly, wouldn't that mean that the battery isn't charged at all ?
In my case the battery is being charged and depleted normally, since I can use the N7 to play games etc.
Only the battery-level indicator keeps telling me the level is at 0% and it says "unknown".
It's just annoying as I don't know when it's fully charged or fully drained.
Now I let it charge for a complete night and work with the tablet untill it dies on me.
Just to let everyone know, who might face the same problem :
I pulled off the back cover and found out that indeed the connector, coming from the battery going to the mainboard, was not fixed in its socket.
It was not completely out of the socket, just not firmly pressed.
So I pressed it firmly and put back the cover.
After restart, the readings are back to normal.
Thanks everyone for pointing me in the right direction.

I have exactly the same problem!! Can you please help me. I tried what you said - removed back cover, pressed the connector hard, and switched on again. The problem is still there. Can you look at this picture - http://android.hdblog.it/wp-content/uploads/2012/07/Nexus-7-Teardown.jpg and tell me if the connector are the red and yellow wires on the left, on the side of the tablet closest to the camera? If so, how did you press it? Could you explain those steps once again please?? Much appreciated!

Make sure you put a piece of tape on the connector to secure both pieces together and also one on the battery to prevent it from shifting. The newer n7's had a battery that didn't fill the space for it...allowing it to shift and pull the connector free.

I had exactly the same issue. Word 4 word.
I took the back off my n7 (take the SIM holder off 1st, makes getting the back off much easier) and noticed the battery connection was loose. Unplugged fully, replugged and got my battery % back! :thumbup:

First off, for everyone that has battery-related problems, please check my thread:
http://forum.xda-developers.com/showthread.php?t=2090826
It provides "fixes" to a number of battery-related issues.
Second, the cover is really easy to get off. Just use your fingernails. Start half-way down one of the long sides (I forget which, but try both - your fingernails will easily slide into the seam). Gently snap off the cover from your starting point. Slowly work your way around. If you go slowly/carefully, it'll come off rather easily and without breaking off any tabs. It snaps back on easily as well.
In my post, I recommend that you apply a small piece of electrical tape on the battery connector, as they have shown over time to come loose for a number of N7 owners.
In all but the occasional rare case, N7's with battery-related issues are easily "fixed" and do not need to be returned for replacement. Just read my thread. It'll save you a lot of time and frustration. It'll also might save you from a needless return!
Good luck and report back.

Strange. my tablet is doing the weird battery bug. Battery stuck @ 100% for quite some time, even after a whole day of idle and @ home usage after work.
Realized it wasn't dropping.
This morning, I opened up the back and checked out the battery. It was glued down so not shifting around, but I noticed there were fingerprints on the copper material. Odd thing is I bought this tablet new. Box was sealed and everything.
So far I unplugged the battery and plugged back in. Haven't turned the device back on just yet. Might wait a couple hours and see.

Yup I stumbled upon your thread after a bit of searching. The tablet was actually rather new, just purchased a week ago. Was charging and draining fine for few days of ownership, and all of a sudden it started acting up. I realized it was too good to be true seeing 100% battery % after a whole day + gaming on it @ home.
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
Hey all at xda,
Recently I purchased, second hand, a Nexus 4. But I have been having massive issues with the battery. Firstly it seems to be completely inaccurate in reading the battery levels. It jumps all over the place, and reports back RIDICULOUS charging speeds. (10 minutes and the phone went form 7% to 95% :S).
The other problem that I have been having aside from those strange sporadic readings is the fact that the phone does not work at all when it's not plugged in. It lasts for 3 or 4 seconds after I unplug it, and then turns off, and appears to bootloop when I attempt to start it back up again, even when I plug it back in. I CAN get into the bootloader and my TWRP recovery perfectly fine and with no issues. TWRP often reports a 25% battery drop despite the fact that I JUST removed its charger.
It still bootloops when I plug the charger back in and let it charge for some time. I actually have to go into recovery and execute a factory reset to be able to get back into the ROM.
Should I try different ROMs?
Originally I put on cyanogenmod 11 kitkat. While I was running through the initial phone setup was the first time I encountered this unplugged issue. Due to this, and the bootloop I thought I had softbricked the phone, and so I reflashed from CWM to TWRP and put on a different ROM.
I upgraded to kitkat 4.4.4 this ROM to be exact. There seemed to be no issue it runs PERFECTLY when plugged in. But still doesn't last when not plugged in, and begins reporting strange battery percentages, eventually turning off completely.
When attempting to restart the phone I get the Google image, with the unlocked padlock at the bottom, and then it goes straight to the battery image with the electricity symbol in the middle. The same occurs when starting from the bootloader. Occasionally the same occurs when attempting to get into twrp but not always.
Is this simply a battery issue, and will replacing the battery solve the issue, or are there larger problems at steak here? Did I get ripped right off by the seller. (Doesn't seem like it, seller told me to contact him if there were any issues and he would do his best to help / solve the problem for me.)
Thanks guys,
Pensai
I would try out some roms and kernels and see what happens. And if nothing helps than contact your retailer and ask for him
Sounds like the battery is bad to me.

I'll try some more rom's and see if the issue persists. Unfortunately contacting my retailer won't help as this is a second hand purchase from an individual, rather than a store/company. (got a sick deal btw 180 for it ).

I'm hoping this is purely the issue, since it's and easy fix, I'll try the above suggestion when I get home from work. (or before hehe) If new roms and kernals don't fix the issue I suppose I'll order a new battery and hope for the best. They're pretty cheap anyway.
Another thing that may be worth mentioning, is that USB charging seems to be useless in giving the battery any juice. It somehow is actually capable of draining quicker than it chargers if left on plugged in. Even turned completely off and just plugged in to charge yields no results. It must be plugged into the wall.
Just a bit of an update, I got home from work and noticed that the screen had begun to separate from the chassis. I suspected that perhaps the battery was bloated, given the issues I have been having. I am now 99% sure it is the battery.
When I took the phone apart, the battery was indeed bloating and and even burst open on the bottom, exposing these 'layers' along with some casing ruptures on the bottom of the battery as well.
I have ordered a new battery and it has shipped. Hopefully a new battery is the nail in the coffin for this issue.

It still is a Li-Po battery. Li-Po and Li-Ion both are types of Lithium-Ion batteries, the difference is that their structure is different
Li-Po is safer and less hazardous

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.

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.

Try this: https://forum.xda-developers.com/showpost.php?p=74268596&postcount=4
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.
