[Q] Battery from 45% to dead immediately?

Last night before going to bed I decided to turn my tablet off (it was around 45% battery left). When I tried to turn it on this morning, it was dead; no response. So I plugged it in and after a few minutes it booted up. I went to the battery settings and saw that it dropped off to dead pretty much instantly. Here's a screenshot after charging for a few hours.
Does anyone know how this happened, if it can happen again, or if it was just a random occurrence?
I'm on stock 4.2.2 rooted, and the only app I installed yesterday was "avast!" security to try it out.

Same thing just happened to me only I had more than 45% and was using it at the time. The screen would flicker every time I would touch it and keep flickering for about 3 secs if I swiped to change home screens. Display went dark and was unresponsive. After plugging it in it finally booted and said I was at 0% battery.

OP: it could be a problem with the reported charge left in the battery, or a hardware defect that is grounding to the chassis and then through you that is sucking all the charge out. No app or anything can possibly drain the battery that fast, even at max load and max CPU speed constantly. The only way charge can leave a device that abrupt and by that large an amount is by a short somewhere in the hardware.
Vindico: sounds like a definite hardware problem to me and the tablet should be replaced. As I said above, there is no possible way in all of electronics and physics for a battery to be drained that fast and suddenly with our hardware in any situation other than a short in the hardware.

45% of charge loss in a few minutes is simply not possible without huge amounts of heat being generated... I assume the calibration or measurement is completely off... Or do you see bubbles coming out of your Nexus 10? :laugh:

I've had this happen to me twice, each around the same 45%. Except i must have caught it pretty much soon after it happened because the tablet was really hot each time, and took about 5 minutes of being plugged in before the charging icon would come up.

This happened to me today, and it happened 2 weeks ago.
While I don't have any technical advice to give, I purchased my tablet in December and Google is replacing my tablet free of charge.
Samsungs quality control on this thing has been pathetic. Here's hoping I get a better copy next time.

Cahce?
Have you tried clearing Battery stats? You should give it a shot, I have had a similar problem with my Galaxy S2 & S3.. It was fixed after i cleared the stats.

Probably a coincidence. Android generates battery stats on boot always. Clearing them does absolutely nothing. That is straight from what Google said when it was all the rage to clear your battery stats when flashing a new ROM or kernel years ago.

Well I think its more of a reportage problem... I have this new nexus 10 which is showing the same problem..
Once my tablet screen flickered and went off... And it responded only after 10-15 min of charging...
Now also at times the battery status will get stuck at some particular percentage and wont update automatically however a reboot will set things straight...
Overall battery life is not diminished so the other scenario of battery being rapidly depleted due to some hardware is quite unlikely...
Besides the whole time the battery was stuck at one particular percentage was when i was actively using it and screen was on... So ideally the battery should have drained during this time...

Bringing this back to life, mine just died at 50%

I have the same problem. Battery is 100%, I disconnect charger and then few seconds/minutes and reset. After reboot it stop at X sign and reset again and again, and again.
When I connect charger Nexus can boot but it shows 0% empty battery! After few seconds/minutes battery shows 100% again.
So I think that my battery is broken (or battery controller at least).
In my opinion Nexus 10 has very poor quality during production (reboots, battery problem, heating problem etc.). So I'll never ever buy a Android tablet again, especially a Nexus line or from Samsung. It is unacceptable for me to sell product with so many bugs.

I just charged to full while the device was off and plugged in, and deleted the battery stats. I'll report how it goes.

No change after deleting battery stats, still shut down at ~32%.
Time for a warranty.

Exact same issue, 2 days in a row :/ Every time it reaches around 50% it powers off and won't turn back on without the charger :/ What do I do? I only got this on Wednesday!

Ughhh just had this happen to me. Hit 32% and boom shut off. Really lime the tablet but this is kind of a deal breaker. Anymore news of a fix. I'm running AOKP 4.2 right now.

Not sure about an actual fix, outside of a battery replacement, etc.
Mine is currently at Samsung for repairs, which has been "fun". I started by sending it in after describing the problem as "while discharging, the battery will drain as it should to about 50%, then immediately to 0% and the tablet shuts off saying the battery is dead". The original call taker, who was really nice, took it as a "charging problem" and didn't say anything to me. The repair status tracking online just said "component replaced" so I decided to call. Turns out they just replaced the charging port, nothing else. Not going to fix my problem though. So, I re-explained the problem and the nice lady said that she should transfer me to advanced tech support. Sweet! Finally someone who knows the issue! WOOT!! Someone named Robert totally understood the problem, put me on hold, and came back and said "Okay, so, just to make sure we really get the problem fixed, I'm having them replace the whole motherboard, battery, and the connection terminals that the battery hooks to" (I forgot the name). "We're taking the shotgun approach here, so hopefully it'll fix your problem. I'm also writing a better description of the light leak in the bottom corner, and having them expedite the repair since it's been here for 5 days already".
Robert, you sir, are my hero today.

Who did you contact for repair? There was nothing in my warranty book about who to contact. The pay store said to contact Samsung directly for the nexus 10

Okay I had the same problem that everybody else here has had. I have reflashed the stock rom and unrooted and locked my Nexus and everything seems to be working perfectly since then. No more reboots freezes or incredibly large battery dropping since then.

battery life falling off a cliff

So this has been happening with my battery lately - it's chugging along no problem, then the second my phone hits 30%, it dies completely, and when you hook it up to a charger, it starts charging from 0%.
This has happened with multiple replacement batteries already. Anyone know what's up?

Was an issue for me back when my battery was bulging. You might want to try and recalibrate the battery if it's new by charging it overnight, if not new then get a new one. If that doesn't help, factory reset. If problem continues, take it to Samsung.

I had the same exact problem with mu Note 10.1 2014 edition. Then I downloaded a battery calibration app. The one I downloaded is made by a developer by the name NeMa. It worked as stated. Couldn not be happier. But, it needs Root. And does not ask for ridiculous permissions. Give it, or another one a shot and report back.

Guys, for years now it's been proven that battery calibration is a myth. The act of charging the battery to 100% has the same effect as it does the same thing as a battery calibration app: delete the batterystats.bin file.
The problem is either with the battery or the charging circuit in the phone. Take it to Samsung and have it looked at, because a battery calibration app won't work here, despite claims to the contrary.

It has been proven as much as evolution. And that is about zero. No proof. It is a theory. Now, you are of the opinion that it is a myth. I am of the persuasion that it is not. Seeing as my Note 10.1, SGS3, and SGS4 all had battery issues for long periods of time. Then I remembered that there is this "myth" called battery calibration. After trying out the "myth", my wife's phone no longer shuts down randomly, my Note 10.1 does not go from 30% to dead instantly and neither does my SGS3. All have batteries that now last exactly as long as the manufacturer specs them out to. And non of them freez up and or shut down any more. All of these devices have been going through these problems for many months now. Tried the "myth". No more problems for this past week. And there are not going to be problems.
So, in my case, the "myth" has gone from the act of being "myth" to fact. Until your device start acting up where battery stats play a roll, then it will stay as such. A myth. Now, if the battery has been through to many charging cycles, then it is probably old and on its way out. In that instance, no battery calibration will bring it back from the state of dying. At that point, it is time to get a new battery.

So you belive everything that you see on TV as well? I suppose that the Internet must be God to you. I mean, there is an http link for everything. Must be fact.
How would you like to explain what happen ed d to all three of my devices that were having g battery issues. SGS3, Would charge to 100% drain down rapidly and when it hit 30% it would just shut down.
SGS4, would drain down to nothing at random and shut down at random. Even in the middle of a call. Note 10.1 2014 edition would drain down extremely fast, and I mean fast. It also would shut down. That one I did replace the battery on. And it still did it. All of these problems have persisted for several months now. Only a week ago did I try the calibration method. Which I am aware, using an app is the short way around deleting the file for the battery. At any rate, all devices are back to normal operations. By the way, I put the old battery back into my Note 10.1, and did the recalibration. AL is well with it also. But, the Internet must be telling the truth. Plain and simple, calibration will not fix a broken battery. It will however reset the part on the system that reads the battery correct and tell the OS what to do with those numbers. In the case of the case of these, my devices, there are no more shut downs happening. Or was all that in my head for months? Probably just a placebo effect? Yeah, that's what it was. The Internet says so. Lol! I'm going to put up a link to a YouTube video that shows that horses are pink.

By the way, I am just having fun with you and bust your chops. Lol! But I still stand by my statements of calibration. It works in some scenarios. Particularly when switching ROMs.

On my old Gingerbread device, I used Nema's Battery Calibration app. Once I read the information from the Google engineer in the link I provided, I stopped, and haven't touched a battery calibration app since. In my experience, calibrating the battery is a needless step, because you aren't actually doing anything to the battery itself or the circuitry within it. For example, you mention using it after changing ROMs. Why? My battery life has not been affected from all the ROM switches I've made in the last year, and I've made plenty of them.
If a battery calibration app were to actually recondition the battery, then I would say such an app is useful. Instead, you have a placebo effect brought about by an app that does nothing that Android itself doesn't already do. So why waste the time, the energy, and the (minuscule) storage space?

Google make Android. So if they say that batterystats.bin has no effect on actual battery life and such, then it must be true. I mean they are the ones who made the damn file, they should know what it relates to.
The reason why your 3 devices worked again after a battery calibration might be something else. Maybe the app you used did something else other than just delete batterystats.bin file.
I also used to calibrate my battery on my old Gingerbread device. But honestly, I didn't see any improvement in battery life by doing this. Nor did I see any worsening in the battery life or sudded death by not calibrating.

First, Google did not make Android. They purchased it and now modify it. But that is besides the point.
Sorry, but the app that I used did one thing and one thing only. And that was clear the file. It did nothing else. Can you tell me what if not battery stats, would make all three of my devices behave properly? Because I would love to know, as would the rest of the community. I seriously do not particularly care what Google stated. I care what was happening with my devices. And they were not working. I used an app to clear a file that has to do with the batteries. All of my devices work exactly as they should. Google can tell me that all rainbows are silver. But, my devices are not telling me one thing about my batteries while something else is the case. And my devices are not shutting down on their own either. So, 3-4 months of serious charging, readouts , and performance issues all cleared up after the use of an app. I am confident coincidence is not the case. But thank you for your disbelief in something. Absolutely appreciated. Plain and simple people, if you are having batteries issues. Try the simplest method. A calibration app. If it works, then great. If not, move on to the next step. Try different charger and or cable. If that fails, chances are that the battery is on its last leg. Replace it. Nothing more, nothing less. Zero arguments to be had. Nothing to prove. Or disprove. If any one is of the persuasion that a calibration app is a waste of time, don't use one. Also a simple thing to not do.

Severe Battery Drain - Battery Historian puts UNACCOUNTED battery usage at 80+%!

2 weeks ago I woke up to a non working headphone jack, and excessive battery depletion. The phone also began to run warm all the time, regardless of screen on/off. With the screen off I'm seeing battery usage at 10-15% or more per hour. At night if I go to bed with a fully charged phone I have an almost dead phone by morning.
The headphone jack gave a lot of electrical feedback/clicking when plugging in headphones, so using a mulitmeter discovered that there was power coming thru the headphone jack - even when the device was powered off. It wasn't much, but I verified this wasn't normal with another working phone. I then removed the headphone jack, but this did not affect the quick draining battery.
I had been on Oreo a few weeks before these issues began, so I downgraded to Nougat, that didn't make any changes, I've ran in safe mode for great lengths, I've upgraded back to Oreo, - nothing seems to affect the battery drain issue.
I purchased a battery from Ebay, it appears to be an OEM Huawei battery, and is almost a year older than the battery that came with my phone. I just put this replacement battery in last nite, to no difference in battery drain.
I began using Battery Historian a few days ago, and do not see anything there to indicate this severe of battery drain. I'm on a BYOD program with my workplace and use Airwatch - Inbox pops up a lot in the wakelocks and cpu usage - but the app usage info doesn't indicate that it is responsible for the severe amounts of drain. I've restricted facebook and messenger from background activity, even uninstalled them for a few days with no difference. Battery Historian Device Power Estimates every time has the following line right on top:
0 UNACCOUNTED 0 89.88%
I understand UNACCOUNTED is ok to be here, but 89% of my battery usage is unknown? If Android doesn't know where my battery usage is going what other options are there?
Could there be a hardware issue? Bad motherboard? I purchased my phone used thru gizmotrader.com - it was in excellent shape. The 1 year warranty from Huawei expired in early September 2017, so the phone was relatively new when I received it. The only "abuse" I can speak to is that I use a vent magnetic mount in my car. The 6P does get warm while fast charging, so I would help keep it cool by allowing the AC to blow on the phone while I'm in the car. Even if it wasn't charging it would have the cold air blown on it. Using Accubattery the battery temp would start off in the low 90's and drop to 70's when charging with the AC blowing on it. I didn't give it much thought before, but I'm beginning to wonder if those temp swings might have caused an internal issue beyond the battery. I'm considering a motherboard swap might be next, but for the cost of that I might as well move on.
Any advice on suggestions for what I could for on the motherboard? Any ideas about usage looking at Battery Historian screenshots?
Thanks!

You need a new battery.

Install Accubattery and see what it says about the state of your battery.

I find it odd that at the very end you mention using Accubattery for temperature readings but nowhere in your (very long) post did you mention the health of either your old or new battery.... why not? Did you not know Accubattery estimates the current capacity of your current battery wrt to a new one? My personal opinion is you don't want to believe that both your old battery and (older) replacement are both bad. Granted the headphone jack is weird but you didn't mention any trauma or water to the phone. I agree with the others that more than likely you need good replacement battery. A motherboard is not economically viable for the N6P, but for now a cheap battery is in order. PS.. If you want a better battery drain app, try using BBStats by a dev here on XDA.

I agree about a new battery. When I ordered the one I just received I was attempting to get as close to OEM as possible. I also believed getting a battery with the temp sensor was important. All that got me was a new, older, battery. Is it safe to get a battery without the temp sensor? Any types to avoid?
I have been using Accubattery, original battery went from 98% health in April, to 97% a few days before my issues began. The "new" battery I just received is showing 85% in Accubattery.
I've also used BBS, I can't get screenshots to load or else I'd share those here of what BBS shows. There doesn't seem to be any clear culprit in any of the information from BBS or Battery Historian.

Yes it is safe to use a new battery w/o a temp sensor. There are dozens of threads identifying which are good batteries and where to purchase them. Cameron Sino is one.
BBS exports a text file from the menu. You can get expert help in the Dev's XDA thread by posting it there. If Accubattery was reporting 97% battery capacity, I would not have changed the battery.... you may have something else going on there, but now you need to change it out. Try running BBS again on a full charge for a full 8+ hours and don't touch the phone, just let it run down. In the morning, pick it up and export the data to text. Analyze/post that file and see if that gives you better data than Battery Historian.

So after a few days of charging and usage, Accubattery has the replacement battery at 99% health. I'll leave that lone for now.
Last evening I decided to do some basic testing and put the headphone jack back in. With the battery unplugged, there was no continuity between the 3 sections on the AUX cord I was testing with. With the battery plugged in, there was continuity. With battery in, I was also picking up 1-2mA coming thru the AUX cord (basic 3 section plug). From what I can find, the normal layout of the plug is ground is closest to base (furthest from tip). I get a negative reading when using that section as the ground, but a positive when putting the positive lead on what should be the ground. Moving the probe between left/right is pulling identical amounts of juice. I then moved on to the temperature issue, using an infrared and the multimeters wired thermometer noticed quick increases in temp when the battery is plugged in. The area with the highest temp was under the shielding directly above the fingerprint sensor, closer to the top right - using iFixit breakdown pics it looks to be the Qualcomm Audio Codec in that vicinity. I played around with this for a bit - unplugging the battery, taking temps, plugging battery in, taking temps - consistently that same spot would be the greatest increase - going from a room temp mid 70's to near 100 in a matter of minutes while powered off. I didn't take the mobo completely out, so I'm aware the heat could be radiating from the other side - but on that exact flip side appears to be the 32Gb flash memory chip, the processor and ram are just below it.
I have the output from BBS, can't seem to post it. Can't add attachments - tried to copy and paste but was blocked because I can't post outside links, which were from the output file... I'm going to stop by a local repair shop today, see if they might be able to offer some assistance.

You can use PasteBin (link) if having a problem with posting a text file to XDA. Dev is really good about helping out. You must know that part is cheap (and the usual culprit for water damage) to replace. You seem to have enough experience or maybe more than the techs you are going to run into (and pay).

Cameron Sino is no longer selling reliable batteries. Several people are reporting they are now wrapping 3000mah generic batteries in their wrappers and claiming 3450mah. I was one of the people scammed by them. Also Beltrons are fake too. To be clear, they work just fine, but only at 3000mah. Or less

That's good to know. I'm in the process of buying a new battery and am still deciding.

To update this, I went to a local repair shop that does micro soldering. They wouldn't touch my Nexus. I was very tempted to buy a small soldering kit and attempt a repair myself. Before I made that purchase tho, I decided to look at buying a damaged phone that I could salvage a motherboard from. I paid $61 for a similar spec phone that had a bad display. I installed the salvaged motherboard last night, and 14 hours in and everything is working fine. Battery lost 3% during the night with all my normal apps and everything installed. Didn't go thru and restrict any background usage yet, so can probably do better there.
I'm going to look at attempting a repair on my original motherboard now that I'm not dependent on its survivability, considering I have limited experience. It will be a learning experience for sure and if I am able to fix it - will be good to have a back up motherboard!
Thanks for the help along the way!

Great news. With a good battery and motherboard you should be good to go for a long time.

Everyone roll your eyes: another battery question.

So, it seems like my battery isn't quite behaving itself. I've turned of Moto Display, underclock GPU to 300mhz, and switched to 1080p instead of 1440p, used Amplify to control wakelocks and Greenify to hibernate things that like to run in the background. I have never gotten more than about 1hr30min of screen time. My phone stays relatively cool unless I'm playing a lot of games or watching a lot of videos on YouTube. I have a handful of xposed plugins (Amplify, GravityBox, Greenify, NougatNavigation Bar (I like the solid icons rather than the lines that comes with stock N) and Status Bar Cleanup).
Anyone think I should get a new battery? Not under warranty, so I can't do anything via that route.
Also, is eBay a good enough place to find a replacement battery as long as I make sure it's not a counterfeit?
Thanks everyone for any help.

Can you be more specific what you mean by your battery not behaving itself? Random shut down or at any particular battery level? Sudden drop off battery percentage ofb10% or more shortly after charger disconnect? Has the unusual battery occurred after any specific updates to any of your apps? Have you tried a factory reset (I know it's painful but it does help on occasion)? Just throwing it out there.

It doesn't make difference - restore default,
used Amplify to control wakelocks and Greenify to hibernate things that like to run in the background.
Doesn't work good on Nougat - you can use "background permission setter" app & "link2sd" for disable some apps
I have never gotten more than about 1hr30min of screen

Standard is ~3-4 hours of SOT with any rom or kernel.

I rarely ever got 3 hours... GSAM's average SOT over time was about 2h 20m... Although I did have occasional instances with 4 hours (on WiFi, reading, at night, very low drainage usage). Not really the point though
Should you replace the battery, well, from what you say it sounds like it is due... The real problem is getting a quality replacement. You can find a ton of them on eBay or other online markets, but most users here will tell you that you can't get an OEM battery any more no matter what the seller says, they just don't exist, and most of the ones that state "new" are just knock-offs or batteries for other devices that are re-purposed (and often of lower capacity). There is a serious market for cell phone batteries, and there are lots of counterfeits out and just out-right lies there, so the real problem is getting a good replacement battery. It is literally luck...
Remember, this device is 2.5 years old... Meaning most batteries for it were likely made prior to that. Although I paint a gloomy picture (it is a bit gloomy) there has to be some decent ones out there, but expect to pay $20+ and it will still be a crap shoot. Remember that when replacing the battery in this device, it isn't the easiest so do your homework. You will likely want a new back cover assembly (door and adhesive) as well because a good majority of the time they get destroyed when performing the operation.
Oh, and before you go down this road I suggest wiping your device... everything... and set it back up with the absolute bare minimum stuff (don't install anything if possible) for a couple days and retest your SOT. Not saying that's the case here, but Nougat's battery/app management is pretty good and we have seen more and more tales of things like Greenify/Amplify and other tweaks for helping battery life having the opposite effect, with some people noting the more they try to tweak it the worse it gets. Just a thought...

Quite a few times my battery would drop ~5-6% just after I remove it from the charger (regular USB power, not the turbo charger). I have tried a factory once and I let the battery do the "break in" period just to see if the battery was calibrated or not. So far it seems it is calibrated...I've also tried draining the battery until it my it shuts off, then using the turbo charger and letting it sit for like ~8 hours (I forget where I saw that specific bit of advice. It was in response to someone else posting...I don't even remember where. Possibly XDA, not 100% sure).

I found my capacity to be 3034mAh...which is....quite odd. My battery isn't even fully charged.

I actually tried to replace the battery once and I did such a terrible job that I ruined the contact points on the ribbon that connects to the main board. I wish I could get a new phone (like a Pixel 2) but I have nowhere near enough income or funds set aside for that. Maybe later this year...hopefully...and not necessarily a Pixel 2 but something that runs very close to stock AOSP. I would definitely miss the 2 front facing speakers on anything else. I saw ZTE Axon 7 and the Razer phone has them too...but no idea how close they are to stock AOSP. Maybe I'll take the plunge into flashing the stock Nougat images and let it be naked for a few days. That sure would be annoying...but if it helps my MXPE survive in good shape until I can afford another phone I'm all in.
Thanks everyone for the help! I'll look into my options and hopefully I can get a bit more time out of this phone until I can afford a newer one that doesn't have the stupid Snapdragon 808. I shake my fist at thee, battery hog!

I'm on Nougat stock and I keep getting battery down at 25-35% regularely. I can see that when I put phone in charge after it shuts down percentage charge numbers start where power down happened at 25-35% Tried a battery calibrate weeks ago with a play store app. At first looked like it got fixed but just for a day or so and back with same problem. Also SoT is terrible, getting max 1h and if i do a heavy use even less and I dont even use social media at all. No idea if its a dead battery or software problem seeing I was on custom rom before i reverted back on stock nougat. Waiting for a decent Nougat modem stock Rom to try it once again to see if a difference or not.

"Battery calibration" apps don't work... The proper way to "recalibrate" a battery in modern Moto devices is https://motorola-global-en-uk.custh...moto-g4-g4-plus/topic/battery/battery-reset/1
Honestly, if this does nothing, try a cache wipe, and if that doesn't help do a factory reset. If that fails as well, then the battery is likely beyond it's useful life (becoming more and more common lately) and will need to be replaced if you can find a quality replacement. There is no "trick" to getting the battery back.
It seems these batteries were engineered for 18-24 months of life and that is about it, as most modern devices themselves are only intended for a max of 24 months of usable life anyway... They sure seem to drop off significantly in charge capacity after that point.

Try this app? AccuBattery
After a couple of charge cycles it shows my battery at 89% of max. My manufacture date is 11-16-2016, so just over a year old. Of course, the battery could have been made before then by some months, I don't know.

Replacing the battery on the Axon 7

Anyone know where i can get the battery replaced on the Axon 7 in the UK? My battery drains too quickly and does not last a day. Ive looked at the videos on Youtube and it looks tricky to replace the battery. I love my Axon 7 especially the front facing speakers.

I replaced mine a few days ago. It's one of the easiest battery replacements I've ever done. It's very easy. Just make sure you have the proper tools

If you look up in Amazon as I can not post the link:
"Cameron Sino 3100mAh Li-Polymer Replacement Battery for ZTE Axon 7"
Just be careful when disconnecting the ribbons and carefully removing the battery from the screen as mine took a lot of finesse and some heat to pry it loose. I now have a great battery but now have no home and back button after attempting to repair many times. Luckily there is an app you can use to at least make my phone usable again.

how did you break those? The ribbon for the buttons is on the other side of the frame... are you sure your screen ribbon is well connected?
Have you tried pushing on the screen roughly where the volume buttons are located, to see if it gets reseated? It's weird that the screen works but it might be just that

I took the phone apart 4 times ensuring the ribbons were well connected hoping that may have been the culprit. Also took the battery out each time, applied pressure all around the screen which makes me think I might have shorted out something. Strange though the right button still works, just the home and back button not functioning.

And this, folks, is exactly why you shouldn't be dissasembling phones unless you're very skilled with with electronics repair. You forget to connect a cable or w/e, then post here with complaints. I'm not physically well coordinated, my hands lack the fine motor skills and dexterity to work with small parts. If I have electronics hardware I need worked on, I take them to a friend's shop and he does the work for a small fee. I get everything back knowing the job is done right.

Hi Karl,
I have pretty basic electronic skills, and I found the battery replacement pretty easy.
There are plenty of guides on youtube, and as long as you have a decent toolkit--spudger, flat metal pry tool, correct sized bits--it should be an easy thing to do.
One step to watch out for is at the beginning; you need a hair dryer/heat gun to loosen the plastic bezels at the top/bottom of the front face. Be careful applying too much heat. My top bezel has a small bend divot from where it got too soft and bent when I removed it.
Just go slow and take your time; I think my take apart and reassembly was just over 30 minutes.
Good luck!

Are you sure that the battery is really the reason?
When I switched to the last LOS 15.1 ROM a few month ago, I noticed a rapid decrease of battery time.
And also the latest version of the imgur-app drains the battery extremely - if active, the battery only lasts for about 4 hours.
(I constantly force-quit it to get over half a day)

that's the kernel, it's probably not too optimized - but it's not necessarily the only reason! If you set up a decent ROM with a good kernel like one of Kran's EAS kernels and still get bad battery life, then you can bet it's the battery (you still don't need to - run Accubattery, let it log for about 3 days, then check the capacity estimate).
I honestly don't know or care about the persist stuff because I've gone through roughly the same ROMs than these guys here and have no such trouble. But I won't deny it
Btw if you get a fast discharge of a couple % after disconnecting the phone or your phone shuts down unexpectedly at 10/20/30%, those are telltale signs of battery degradation.

Introducing too many variables can confuse the issue.
I've been on the same rom since 9/2017 - RR 14.x based. I used to go 2 days between charges, now it's 1 day. Usage hasn't change all that much. I have a battery on order. I'd also like to update to 15.1. Goal is not to do any upgrading until at least a week or two after installing the new battery. Otherwise, existing SoT and battery usage numbers will have little value.
Of course, it's a good idea to perform a backup (twrp/titaniuam) for anyone replacing the battery just in case something goes wrong along the way and your phone turns into a brick.

Latest LOS 15.1 Unofficial fix this for me. Maybe dev make better the kernel now.

Hello,
Speaker grills can be bought on Ali... easily so no problem at all for battery replacement BTW. you can buy original ZTE battery on Ali too.

You think there's much difference between an oem and third party battery? I'm only two charges in on the cameron sino, but still showing about 2700 mAh with accubattery. Tempted to get one of those usb amp meters to see what it's really taking in.

So far 3 full charges (1-2% to 100%). Accubattery still showing ~2650-2700 mAh capacity.
Actual use seems to be restored. Note the pic below.

point is, there is pretty much no way to know whether the battery you are buying is original or not. many bought the original looking ones and they have the font slightly off, knockoff-like... Which doesn't matter anyways because they perform just as good (or bad?) as a new OEM battery.

well, you could claim a bad battery if that's the case. 2700 mAh is just dead

Past use wasn't quite the same. I'd typically recharge around 40% (to 100%). Getting to 40% would take less than a day. So there's definitely more life to it. Going 2 days between charges would be satisfactory.
I'll give it another full cycle to see how it's doing. Not sure another battery would make a significant difference. Seller might offer an exchange but is it really worth the hassle.........

you don't get it entirely. If that battery really has 2700 mAh, its capacity is about to fall off a cliff, and your phone will start having early shutdowns whenever you give it any load. that's pretty much how it works with lithium, it is advised to change the battery when it is at 80% capacity since it'll start behaving like crap in no time
Our batteries probably have a newer/better chemistry than those on the picture (they are charged at 4.4V), but the concept is the same.

Accubattery indicated ~2000/2100 mAh for the old battery. In terms of actual use I'd be at ~30% by the end of the day with my typical use. Phone never shut down/rebooted. I don't play games or run cpu benchmarks. Probably the most intensive activity would be creating twrp backups with compression, titaniumbackups, playing youtube (hd), or running speed tests (symmetrical gigabit network). We'll see how the phone works after a month. This was an ebay/paypal transaction so there's 180 days to make any sort of claim on it. It's a $16 battery - If I'm able to go two days between charges like I used to, I'll be a happy camper regardless what the app says. I do have one of those KEWEISI amp meters on order so it'll be interesting how that compares to the app.

that's weird. if anything i can tell you i had lots of shutdowns when my battery was at 2500 mAh, and people around here are using batteries around the same capacity with the same problems.
But it's possible that you just don't abuse it that much, I'm talking about 100% CPU usage, for example taking an HDR+ enhanced pic with GCam (CPU pegged, 10+ pictures snapped in a second). there was no way to do that with less than 30% battery, it shut down immediately.
still, i guess you saw the graph. Please tell me how it goes with the charge counter, it might just be that Accubattery is off by ~400 mAh and that's why you didn't get nearly as much trouble with the older battery.
