[Q] Please help. Phone not turning on after battery drained to zero

I gave my phone for repair to Sony, got it after 1.5 months. They said my battery is too low, so gave me another one just to check if the phone is working properly. I came home back, and the phone has been on charge for 2 hrs but it is not yet turning on, with LED continuously blinking red. After some research, I think that the reason is phone won't allow the battery to charge as it has drained to zero, and I need to jump start it by charging externally. But I don't have an external charger. I don't want to approach stupid Sony customer care again as I have had enough of them. Someone please help.:crying:

Have you checked the battery slot? Maybe its not reading/connecting properly... Try cleaning it up. Or leave battery out for a few minutes.

Have searched the forum to death regarding this and tried everything. The battery slot seems fine. Either Sony has damaged my phone's charging circuitry, or the problem is the complete battery drain. Do I need to charge the phone for several more hours? Is the battery now unusable after draining to zero?

Get a USB cable that you dont need and cut the mini end off to expose the wires. Plug the big end into a charging source (either PC or wall charger). Take the battery out of your phone and hold the red wire to the positive and the black to the negative( the battery terminals are marked), you will have to do this for at least 15 minutes or if you can use sellotape or blu tack for a longer period. This will hopefully put enough charge into the battery so that when it is reinserted into the phone it will be able to charge it normally. This is a common android problem.

Thanks infinite times, you r genius, that was the solution I was looking for. You saved me another trip to stupid Sony customer care. It is funny that despite these days of sophisticated technology, I had to resort to such primitive method for charging just because of the lazy manufacturers who want everything done by the readymade OS and cannot put in some extra hardware to overcome a serious and obvious defect. Thanks again.:good:

Your mother board might have a short. My previous phone have this issue and I had to use another Play to charge the battery. It also had battery drainage over night. I would recommend getting an external charger and extra battery, they're fairly cheap.

[Q] Non-Removable Battery novice idea

Hi Guys,
I'm new to the LG G2; so new I don't even have it yet. It's coming from Sprint soon to my doorstep. This will be my first non-removable battery device so I'm thinking and thought about this: What if while the phone was on the charger, there was some kind of a mod to bypass the battery and go straight to powering the phone? Then, it wouldn't degrade the battery and the lifespan of the battery would increase. Driving in our cars or sitting at home would just stay plugged in and not wast battery longevity. Pie-in-the-sky? Probably so, but I had to just put it out here to find out what folks that certainly know more that I, have to say.

Every modern piece of technology does that already.
It's not that charger that is causing damage to the battery. It's the charging itself.

Yes, sir, that is what I am saying also. So, what I am wondering is, is there a way to stop the charger from charging the battery, but still let it supply power to the device so the device works - basically bypassing the battery?

Idk i still charge my battery over night.

The phones coming out now-a-days sometimes have some work-arounds implemented to help alleviate this condition. Some of them will switch off charging at, say 95-99% of capacity instead of charging to completely full. Others will charge to a certain high value and then switch to battery only for the first 5% or so and then start charging again.
Also, FYI, the back cover is removable on this phone if you pry where the hole created by removing the microSIM is. Supposedly it comes off rather easily. Now I know removable back and removable battery are two different things but it is at least looking up!

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] [Issue]: Weird behaviour and battery problems

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.

I don't know much about battery tech, but the front of the battery says Li-Ion, should I concerned since I've handled it with my bare hands?

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

Thank you for the info, It makes sense now with the 'polymer' after the Li-Ion. Also, that video was quite amusing to say the least. :laugh:

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.

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

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.

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.
