[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

The Battery issue

I've been doing tons of research on this whole battery draining issue on the 6p. I cant seem to find a simple solution around this tired issue that plenty of people seem to be having. My battery has about 3 Hrs of screen on time before it dies. I've tried shutting down all kinds of connection settings, clearing the cache and even factory reseting my phone. I just recently tired the android O beta and that didn't help either. All I want is to figure out if my battery needs to be replaced or is it the software that's killing my battery. I've even called google and they cant help, Huawei wants to charge me $165 for a replacement battery and thats way too much. Has anybody found a fix that doesn't involve rooting the phone?

It is NOT the software. There is no fix for a badly degraded battery. Replace your battery. Buy the battery online and then shop around for a local shop to install it if you're not able to.

Are you dying at 60% or lower? Does it happen when you open the camera? Does the phone shut off when a random loud sound plays or something of sorts? I ask cause that is what is happening to me. Random reboots? I don't think that is "battery" related per-say.

Have you tried installing a battery stats app that can help narrow down the culprit?
More details would probably help others help you.
Does it fully charge?
How long does the battery last, not just screen on time?
3 hours SOT doesn't sound terrible. I've heard worse.
How old is the phone?

Had the same problem...I bought a new original battery from ebay and replaced the old battery by myself. To be honest, there was not much improvement...now with a medium usage (whatsapp, wifi or 4g always on, some clash of clans/clash royale gaming) I get 3hrs30min SOT at the late evening, never more. And also I'm on francokernel so I should easily get 4hrs but nothing.
Anyway, unless you are an expert, I don't recommend you to replace the battery for yourself because, sadly, the N6P is a phone impossible to open up without damaging it especially the rear glass...surprisingly, on my case it didn't break but it's all scratched and I should buy a new one.
Furthermore, now my battery doesn't charge anymore up to 100%...it's stuck at 93% and only if i unplug and plug again the phone it gets to 98%...to get 100% i have to plug and unplg it several times and wait something like 30min to get from 98% to 100%. I don't know what caused this problem but it looks like there's no solution...software and hardware battery calibration didn't do anything. Maybe the battery I bought was faulty...
In conclusion, buy the new battery but ask someone expert to replace it if you aren't.

The first replacement battery I tried acted like that and it was quite frustrating. It wouldn't charge to 100% and had about the capacity of my degraded OEM battery. I ended up ordering this one http://www.ebay.com/itm/New-3-82V-3...wei-Google-Nexus-6P-H1511-H1512-/351786248092 It charges to 100% and has like new capacity, but no internal battery temperature sensor. I installed it in January and have been happy with it. Others have opted for the Cameron Sino brand replacement. more expensive but with working battery temperature sensor.
You can order a replacement back cover with glass and bottom strip for around $25 if you're worrried about scratches. That's under $40 for new battery, aluminum back, camera glass, and bottom strip.

I think I'll go for the Cameron Sino battery...a little more expensive, yes, but more reliable...I've also heard of people complaining that after 2 months their batteries (ordered from ebay, false OEM) died...

So, is that the answer to our fast draining battery issues? To get a replacement battery? The Cameron Sino?

Yes.

Unless it came from the play store where you can RMA it and let Google have the problem.

But if Google replaces it, it may have the same issues, right?

It could I guess if the battery in the replacement device is a dud. Just got my replacement and the battery is showing 106% capacity compared to 30% capacity on the old one. Back to how it was when I first got it so happy with that service seeing as it was nearly 2 years old.
If the new one does not have a full capacity, then just reject it before you swap over to it and get Google to send out another.

How are you checking the capacity?

Accubattery is one way. Do a couple of decent charges with the screen off and then look at the health report.

Same, I tried several things, clearing the Cache, factory reset and nothing works. My Nexus 6P randomly shuts down between 80% to 90% and doesn't turn on umless I connect it to the charger.

Battery won't charge, even after I replaced it.

I smashed my Moto X Style screen. I tried to replace it manually, and when I turned it on it wouldn't charge beyond about 3-4%. When I unplugged, it would die instantly. I figured I may have shorted the battery in the process of replacing the screen.
I have now replaced the battery, and I'm still getting the same issue. I've tried a factory reset, different chargers, cleaning the motherboard contacts, replugging the battery several times... It will still not charge beyond about 32%. I can't post a screenshot of Ampere because I've 3 posts, so I'll type it out instead I guess:
Status: Discharging
Plugged: AC Charger
Level: 28%
Health: Cold
Technology: Li-Ion
Temperature: -22.5C
Voltage: 3.762 V
XT1572
7.0
NPHS25.200-15-8
I don't know why it's saying it's cold. It'll display totally different levels all the time. I've been trying to drain it to 0% to recalibrate it. It got to 1%, turned off, but I was able to turn it on another 2 times. I've plugged it in, and now it says 13%. The battery has never gotten warm whilst plugged in and I left it plugged in overnight but it only had "15%".
I've asked on so many forums and I've not gotten an answer to this. Does anyone know what could be wrong?

Sounds like the mainboard connector got broken, perhaps inside where you can't see it, or one of the micro-solder joints... My guess is you need a new mainboard, which for that amount of work you might as well just replace the whole thing.

It did sound like something on the motherboard was most likely broken, wanted to make sure. At that time I gave up and ordered a 3T, but I really liked the Moto X and wanted to give another try and repairing it.

The LCD on my device has a black line going down the side so that's a no-go.

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.
