1. Turn your device ON, charge the device for 8 hours or more
2. Unplug the device,turn the phone OFF, charge for 1 hour
3. Unplug the device, turn ON wait 2 minutes (basically when the phone is all booted up and ready), turn OFF, charge for 1 hour
Happy longer battery life everyone!

Ive done the method from that thread and it worked the first time, second time and more didnt see any difference really unless you do that every charge but i guess that would just kill the battery
I have done all the above and did't see any changes
Would be nice if this would work, but I doubt it...
That doesnt do anything, i get good battery from not having any auto sync updates, brightness is low, widgets for 3g, gps wifi etc.. thats how i get up to 2 days normal usage on full load.
Didn't make any significant changes to mine. I guess if it ever really works then this would be a brain new, never charged battery.
I can only make like up to 24:00 (no use), usualy 7-10 hours of moderate use, can kill in an hour our two on gps.

I used this method when I got Desire and it worked very well! In a meanwhile my battery life weakened, probably because of new ROMs and kernels...so should I repeat this to extend battery life?
that reads like overloading the battery. didnt that just work for the old type of batteries?
HTC uses Ni-MH batts, guys. These things attain long lifespans through two things mostly:
a) keeping it protected from extreme temperatures
b) frequent top-ups
I don't think the idea of keeping it plugged in after full charge is a good idea. The ff is from batteryuniversity.com:
"Lithium-ion suffers stress when exposed to heat and kept at a high charge voltage.
Elevated temperature is anything that dwells above 30°C (86°F), and a high voltage is higher than 4.10V/cell. When estimating longevity, these conditions are difficult to assess because the battery state is in constant flux, and so is the temperature in which it operates. Exposing the battery to high temperature and being at full state-of-charge for an extended time can be more damaging than cycling."
Doesn't work for me I really need more battery life!
I learned a long time ago, even before my smart phone days, that battery life is something I'll never had.
Quick fixes will never work, but preparedness will. For instance; I have 3 charging cables. 1 at home, 1 at work and one in my car. I even had a spare battery for my previous phone.
Things like the first post, I'll never bother trying. It's silly. And looking at the poll results says it all.
I recently did it and I got 2 days out of my battery.
But I assume it will weaken over time and slowly have no effect.

What kernel is your ROM using?
Kernel's have a big impact on the life of your battery. I know mine doubled switching from kernels.
my phone has just recently started to give me the 15% warning then 2 minutes later switch off.
I used to get 10% and 5% before auto shut down.
I'm debranded orange on stock
2.2 2.29.405.5 (release keys)
kernel
2.6.32.15 [email protected]#1 (whatever that means)
Is this caused by software/rom based issues or is my battery on the way out?
(I did the fix in the OP and it did have a positive effect but that was months ago)
don't believe it's a good idea

How to smart charge the Galaxy Note 2 battery
The way you charge your device is very important and it can affect your battery life a lot. Charging it wrong will make it drain quickly and the battery will also last less, requiring a replacement after 1-2 years of use.
To smart charge the Galaxy Note 2, you have to only plug it in when the battery is below the 10% level and never unplug it until it is 100% charged.
You should also know that when your battery reaches 10%, it will last longer than usual. To understand better, it will drain much slower from 10% to 0% than from 20% to 10%. So don’t panic if your battery level is low, because it can hold for a very long time, especially in standby mode.
Never use low quality chargers, because they can damage your battery hand even the device. Only use original Galaxy Note 2 chargers and try not to use the USB cable for charging your device. Always charge it in the wall socket, because the USB port power fluctuates and can damage the battery. Also it will charge much slower.
Battery maintenance
Usually the battery is the first smartphone component that dies, having a lower lifecycle. Though you can prevent this by taking care of it.
The best way to prevent it from getting damaged is to avoid pulling it from its socket. The battery has some golden pins that can scratch or get dusty, so if you pull it out and back in multiple times you can damage the pins.
In order to help the battery work the way it should, always make sure to clean the pins with a soft cloth whenever you pull it out. This way you will keep dust away from them.
When buying a new Galaxy Note 2 battery, make sure to get an original one, as other might have a lower battery life and can have a shorter lifecycle.
Increase Galaxy Note battery life by disabling features
The Samsung Galaxy Note 2 N7100 comes with tons as features, like we just said at the beginning. But nearly all of them are big battery eaters and you need to be careful when activating them.
The CPU and display drain a lot of battery, so make sure to setup the display to turn off faster. Also don’t keep it turned on when you don’t need it.
3G and 4G are the biggest battery drainers on a smartphone. You should only keep the 3G or 4G network activated when you use the internet actively. If you really need a permanent internet connection, then go for 2G, though this eats your battery too. The best way is to only connect to the internet when you need it.
Do not keep the WiFi,Bluetooth and GPS activated when you don’t use them. They can drain your battery very fast even in idle mode, so make sure to disable them when you don’t need them anymore.
Live wallpapers are also big battery drainers. They consume a lot of CPU and RAM resources and also use your display more intensively. So you should never choose a live wallpaper. The most battery-friendly wallpaper is a dark one, which doesn’t use any CPU resources and also doesn’t requires the display to be very bright.
You also have to take care what apps you install and always look at Settings > battery to see who drains the most battery. There are some apps than run continuously and prevent your device from getting into “Deep Sleep.” This is the standby mode that helps the device conserve very much energy. If an app prevents it from getting into this mode, you will notice a very low battery life.
Please let us know if you found other ways to increase the Galaxy Note 2 battery life. We are also curious for how long did you manage to get your device running between charges.
wow thanks mate quite a good one!
Thanks!
Also you should add that if you always need to be connected to internet then its better to keep connected through WiFi as it consumes less energy than using EDGE or 3G.

What?
No.
1. Deep charge cycles on a lithium battery accelerate the failure of the battery.
2. The device can determine the type of source it's plugged into, computer usb ports are safe.
3. Non branded chargers are safe if they are quality made. You just need to stick with quality and 2 amp/ short cables for decent charge times.
Sorry man, but those 3 things you listed are some pretty big misinformation that can easily be verified.
There's nothing "smart" about doing a deep discharge if your trying to preserve a 10 dollar battery.
After installing the new rom..I charge my battery full..then remove battery stats then drain full to zero for cycle.after complete ..I use smart charge method..that is .when my cell battery below to 10 something like 9 or 8 then I connect charger .and really it helps me alot

Deep charge cycles are for avoid "memory effect" and It apply to old Ni-Cd / Ni-MH batteries. Don't apply for modern Li-Ion battery. There is much more chance that the deep drain affect negatively the battery of a GN2.
Li-Ion battery keep better performance if never going less than 50%. But the difference will be barely noticeable.
Personally, after several tests on my own, I don't bother anymore with that (I mean for the modern Li-Ion type). Sometime you have a great battery, sometime a crappy one from a bad batch. I have seen battery died fast after "by the book" charges cycles. And others seem to last forever, no matter how bad I maintained her (like my 2006's laptop).
Anyway, thanks for sharing, even if you are wrong on this one
I don't know if you're wrong or right because when you search the net about battery charging, you find everything and it's opposite. But I disagree on three points:
- The battery is beefy and you really have to work hard to make it last less than a day
- I bought this incredible phone because of it's features. If I have to cut half of them to avoid drain, why did I buy it?
- I dare say that most of the people who buy a Note 2 somewhere are a bit "Tech-Nuts". If you're not, I am, so I don't mind if my battery doesn't last two years because I'm not sure that I will still have this phone all that long.
And if I do and the battery is dead, I'll buy a new, genuine, Sammy one to continue.
What's it worth to live 100 years if you can't have a drink from time to time, maybe have a smoke or whatever? Plug your phone in or out and use your GNote 2 happy
Lol everything has its cost turn off everything to save battery what is fun in that I have a smartphone to use it and be happy with animations and display and games otherwise get a 3310 it is best

How is everyone finding the battery life. Personally, I am finding it just plain horrible. I'm not sure what the issue is specifically but either something is draining it or it is just really that bad, in which case I will return it. I can't get a day's worth of moderate use out of it. It seems to be at most half of what I get from my note 10.1 and they aren't set up any differently. I've tried some of the basics like turning down the screen brightness (which annoys me), turning off the smart stay (but why have a feature you can't use), tweaking email checking settings, turning off samsung sync, turning off bluetooth (don't use it), and locations services. Is anyone else seeing this as an issue and does anyone have any additional suggestions for me to try?
Thanks in Advance
I get about two days between charges on mine. I get a decent amount of usage on a daily basis between email, Facebook, and candy crush. I even have Google Now running. How many charge cycles have you been through?

If by charge cycles you mean fully discharging the phone until it shuts off, I haven't done that, but could give it a shot. It has gone down to 10% several times though.
No battery problems here. I wouldn't blame charge cycles, if they have any effect at all, it is minor. If I were you, I would do a factory reset, followed by an exchange if the reset doesn't fix it.
I have smart stay on , backlight on auto, and take no extra precautions for battery savings.

Can you please post some screen shots of your battery life at the end of a typical cycle? It will help with comparisons by giving us more details on your running apps, screen-on display times, etc. Also, what wakelocks do you have? Use BetterBatteryStats or Wakelock Detector from the Play store for that. This info might help us to identify just how much drain is related to rogue apps or the general battery life itself.

Thanks. Just downloaded BetterBatteryStatus. I'll let it run for a bit and see what comes up. I'll post what I came up with with screen shots from it. Thanks for pointing me in a direction.
Also, it'd help to know how many hours "just plain horrible" is.
I'm not delighted by the battery life I'm seeing, I'm finding I want to charge every night, and that I can easily consume 15% / hour or more even without the screen turned up past 20-25%. (watching video off the NAS in the house.)
Then again, this is the first LCD display I've been able to read in full sunlight, and that's remarkable to me. I often wind up with full sun in the morning when I get up, and am delighted that if I did charge overnight I can use the device even then.
The battery needs some initial "training".
Charge fully on the first and run it all the way down to nearly zero, and fully charge again.
DO NOT interrupt the initial charge.
Battery life is great here after 5 cycles running it to 1% and recharging full at first it was draining faster but now I can watch 4 hours of netflix and still have 25% left nice thing is that the battery charges superfast so no worries

10% is just fine, for purposes of calibrating the battery meter. Preferable actually. You shouldn't actually drain the device until shutdown. There are safeguards that are supposed to ensure the battery voltage does not drop too low (its not actually zero when the phone shuts down). However, in reality these safeguards are not always failsafe and I've seen plenty of cases on various Android devices where letting the battery drain to shutoff renders the battery unable to take a charge (below the minimum threshold voltage). Sometimes, letting the battery charge overnight will bring the battery back. Otherwise, you are pretty screwed, as the only remedy would be a battery meter with a boost function.
In any case, the battery meter is not very accurate, even under the best of circumstances, so letting it drain to 10% is plenty accurate enough. Then let it charge to 100%, and let it sit at full for a while, as fully saturating the battery takes extra time.
---------- Post added at 11:15 AM ---------- Previous post was at 11:08 AM ----------
That said, its hard to say what "moderate use" means. Everyone uses their devices differently. If you are playing intensive games, downloading files, heavy internet usage, it can drain the battery much faster than other activities. And the number of hours of screen-on time is key. So the idea of getting some battery stats and screenshots, is a good one.
I haven't been tracking screen-on time myself. But I find the battery to be decent. I use it a good amount in the evening (don't bring it to work) mostly for reading and web browsing. I have brightness on 40-50% usually (sometimes less, if the room is darker). The battery was just under 40% after 2 nights of use (maybe 40 hours after the last charge). Just guessing, but maybe 3 or 4 hours of screen on time?
Some online reviews mentioned the battery life is not as good as some other comparable devices (such as Nexus 7 and iPad Mini). Not surprising, since the Note 8 has a faster processor and higher resolution screen than either. And so far, battery life is not amazing, but seems comparable or better (better drain while idle) than my old HTC Flyer tablet. So for me, thats just fine.
I got about 4 hours screen-on time on my first battery cycle with heavy usage. Was playing games, movies, internet browsing, etc. My second and third cycles were better, giving me 5-6 hours screen-on time with moderate to heavy usage. Didn't really play any movies, but did play a fair amount of games and stuff.
On those later cycles my screen-on drain represented about 85% of my overall drain. This leads me to say that you can expect 4.5-6.5 hours of screen-on time with the Note 8, depending on usage. Keep in mind that I keep wifi always on, disabled bluetooth/auto-sync/smart stay, stopped some running apps like Maps and Factory Test, and kept brightness down to about 15% of the max setting.
Screen is definitely the big drain here, and these results lead me to believe that even with root and apps like Greenify I would not get much better results. Looks like any further battery savings will need to come from a custom kernel and custom rom (unless maybe you root and then underclock/undervolt using a third party app like Voltage Control or SetCpu). Anyone else have similar (or different ) results?

While his terminology might have been a bit clumsy, he is not completely incorrect.
The terminology of "training the battery" invokes the concepts of conditioning the old technology NiCad batteries to prevent memory effects, which are not a concern with Li ion batteries, which is what you seem to be referring to. Folks on XDA will often talk about conditioning or calibrating the battery, which can be a bit misleading (as often they have the behavior of the old NiCad batteries in mind when saying this).
However, it is true that the battery meter needs to be calibrated to be completely accurate. This calibration has no chemical effect on the battery itself (like it does with NiCad batteries) but simply effects how the current readings are displayed by the % battery meter on the device's screen. Without fully charging and draining the device, it doesn't have fully accurate "flags" associated the current to battery %.
http://batteryuniversity.com/learn/article/battery_calibration
Failure to calibrate the meter won't have a negative chemical effect, like failure to periodically condition a NiCad battery. And therefore it won't have an affect on the battery life. But properly calibrating will give you the most accurate % battery reading possible. The battery meter is not accurate out of the box, after a ROM flash, and an OTA may also reset the calibration.
As I've already mentioned in a previous response, I don't recommend draining the battery to shutoff. As doing so can lead to the battery no longer taking a charge, and the device no longer powering on. Its rare, but it does happen. Fully changing, then draining to 10% or so is enough. Full cycles are also not good for the long term life of the battery, although just doing it once every few months is still acceptable.

The charger for the Note 8 is 2 Amps, while most MicroUSB chargers (at least for phones and other small devices) are 1 Amp. Although this varies, and there are other tablet chargers that are also 2 Amps; but these are far less common than phone charges that just about anyone with a phone that isn't Apple will have.
What this means is that the 1 Amp charger will charge the Note 8 very slowly. I tried mine on a 1 Amp charger just once so far. Left it on for maybe an hour, and the charge only increased by a few percent.
So yes, you can charge with most MicroUSB chargers in a pinch. But it will be slow.

Don't get the physical plug of a charger confuse you - I believe this tablet needs a 2amp output from the charger, meaning just because your charger has the same end connection, it won't necessarily help you charge this battery. I've had my users come to me thinking their devices are defective because they somehow started charging their tablet with their Bluetooth headset charger.
Someone also mentioned the black wallpaper that might help with the battery consumption - I believe that is only helpful on AMOLED screens that Samsung has used on other devices.
I'm really still on the fence on keeping it after I bought this - I'm coming from a GT 7.7 which had excellent build quality,screen, and battery life. The loss of the AMOLED screen for both graphics and battery efficiency is bothering me. I put both up side by side and feel disappointed that Samsung couldn't just make a JB updated 7.7 with new CPU, 2GB RAM, and stylus with the same design and beautiful Super AMOLED Plus screen. It's not even the price - but just feeling like I'm getting a somewhat inferior device (in a few but important aspects) from the 7.7, when it's supposed to be an upgrade to the older device.
I've seen the news about an upgrade to the 7.7 possibly coming, but will it come with the stylus that is also important to me and the other software enhancements from the Note 8?

Funny thing happened on mine.
The battery was VERY BAD the second day, but it could play live streaming for two hours when the battery was 1%. As soon as the tablet went off due to depleted battery, I charged it until it went all the way until the "full battery" came up.
After that, the battery is much better now, so don't say anything "dumb" or any nonsense because it works.

That is correct, having a black background does not effect battery life on LCD screens.
On AMOLED screens, black pixels are actually not emitting light (while pixels displaying other colors emit light), which is why a black background will cause less battery drain than other colors.
On an LCD, the liquid crystal layer that depicts the colors is not itself a source of light. Its lit from the back, and the light intensity of the backlight is the same regardless of what color is being displayed. How much light is blocked or let though by the liquid crystal layer varies depending on their alignment (what color is being displayed). But this doesn't affect how bright the backlight is, anymore than pulling a window blind makes the sun burn less hydrogen.

Hello everybody.
I just want to share with you guys what I found out.
I've been using custom ROMs and custom kernels for LG V30, and I faced a lot of issues. The most common issue is overheating, especially on charging or using mobile data.
I use Anker's adapter that supports Quick Charge 3.0, and an Anker USB-C to USB-3.0 cable. I use Ampere app to see how the battery is charge.
On custom ROMs, the ampere number (mA) changes every few seconds, jumps up and down with big gap, and the phone gets very hot.
On stock ROM (US99820H) in my case, mA number is very stable. It increases or decreases slowly and doesn't jump up and down. On plugging in, min and max mA are equal. The phone is just a little bit hotter than before plugging in.
So I just wanted to share my own experience with you guys. If you want you phone to last long, use Stock ROMs, disable bloatwares and useless system apps.
I'm going to purchase the battery and change it myself for better battery life. I wanted to change to another phone but for now, this is the best phone for music.
Please discuss if you disagree with me or have a solution for custom ROMs.

I've been using custom ROMs and custom kernels for LG V30, and I faced a lot of issues. The most common issue is overheating, especially on charging or using mobile data.
I use Anker's adapter that supports Quick Charge 3.0, and an Anker USB-C to USB-3.0 cable. I use Ampere app to see how the battery is charge.
On custom ROMs, the ampere number (mA) changes every few seconds, jumps up and down with big gap, and the phone gets very hot.
On stock ROM (US99820H) in my case, mA number is very stable. It increases or decreases slowly and doesn't jump up and down. On plugging in, min and max mA are equal. The phone is just a little bit hotter than before plugging in.
So I just wanted to share my own experience with you guys. If you want you phone to last long, use Stock ROMs, disable bloatwares and useless system apps.
I'm going to purchase the battery and change it myself for better battery life. I wanted to change to another phone but for now, this is the best phone for music.
Please discuss if you disagree with me or have a solution for custom ROMs.

In terms of stability, I have different results, when I charge using a custom rom the phone tends to stay cool, but when I used the stock rom the phone got a lot hotter then before charging.
Custom ROMs may not be utilizing QC properly. QC 2.0 has few discrete voltage/current steps, while QC 3.0 has many (200mA increments iirc) designed to strike a balance between charging speed and heat. Maybe it's getting stuck in QC 2.0 mode and the temperature feedback isn't working properly?
You could just use a non-fast-charging wireless charger, if you're only charging up at night. 5v/~1A is pretty much harmless, it's just on the slow side of things.
fyi, battery capacity (as tracked by the charging controller driver, I guess) is stored at sys/class/power_supply/bms/charge_full; it defaults to design capacity until a full charge cycle has been completed* and then I suppose is revised each time the driver tracks less energy has been stored after a complete charge. Cycle count, cell resistance and a couple other things are also stored here. I think all values are persistent until the battery is physically disconnected.
Might be worth doing a full discharge+charge (to 100%, then let it sit for a few hours to saturate) to see if your battery is worn enough to warrant pulling the phone apart. Accubattery does seem to be more or less accurate, so you charge while it's on you can get a real-time idea of how much has gone in.
* a full charge might be from 1% to 100%. It might be from 5% to 100%. Who knows! I've charged from 2% to 100% a couple times and not had cycle_count increase.
Also, if you do go shopping, beware of undersized batteries. I bought an "OE spec" battery a while ago that was obviously thinner and lighter than the original; it weighed some 12.5% less and only took a 3000mah charge, more or less lining up with the reduced weight. The seller was "tele*cell", and I very much doubt they're the only ones pulling this crap. Record the contents of power_supply/bms if they're important to you, too, as they zero out upon battery disconnect.
edit: hmm, thinking about it...bms = Battery Management System? (not this one specifically, of course)

It is possible that you bought a smaller battery - but you should know that the capacity of Li** batteries increases within the first couple of cycles. Also usually the nominal capacity might be different from the real (typical) capacity. So you would need to meassure a.new original battery against your replacement battery (not take the value LG tells us for.granted)

Li-po capacity hasn't really gone anywhere in a while, and I wouldn't expect cheap eBay batteries to be using the newest and best chemistry. It was definitely undersize/weight; I attached some pictures.
Because I wanted to be absolutely sure before I called the seller on it, I purposefully ran it four full cycles, then built up another two during normal use. The best capacity that the BMS ever rated it for was 2980mah, while Accubattery put in something like...3060mah once with subsequent charges in the 2900-3000 range.
While I get what you're saying, I find it unlikely that the BMS would set to the expected design capacity if they were using undersize batteries from the factory.
The reason being that at a guess, the battery "fuel gauge" is probably based on capacity_full, which = capacity_full_design until set. With a new phone that isn't charged to 100% (thus setting capacity_full), if using the phone down to 1% you'd risk either a) the phone suddenly shutting down at ~10% or b) overdischarge damage if the battery is actually less than the phone's design capacity.
Kind of a corner case though, I'll admit, since this would only be on the first run.
Last, I submit my own OEM battery for consideration: prior to taking it out, it had accumulated 537 cycles and had a recorded capacity of 2485mah. That's about what I'd expect from a 3300mah battery that was almost certainly used "normally" e.g. discharged daily, charged nightly and left on the tap at full charge for hours on end.
Like you said, though, the only way to know for sure would be testing a new OEM battery, and we've been fresh out of those for a year and a half now. Maybe someone could nab one from one of their newer models and test for science? I already have too many spare lipo cells laying around.

Do you have sleep problem after changing the battery? After changing the battery, my phone doesn't go to sleep when the screen is off, so the battery just keeps draining. I'm using stock ROM. I don't know if this is a software of hardware issue.

The only thing notable that happened was the battery stats getting wiped. Otherwise the phone behaved normally.
Try getting BetterBatteryStats, second post has the newest apk attached (2.3 iirc).
Start it up to get it established, Set Custom Ref. from the menu, shut the screen off for...ehh...20min.
Turn it back on, select Custom in the left drop-down menu and Current in the right drop-down menu.
Check Kernel Wakelocks and Partial Wakelocks using the top drop-down menu to see if anything sticks out.

What is the full capacity when you put those 2 battery in?
I just bought a battery. This new one has 6 symbols each line (like the one you bought) and 2 lines of manufactured date. The old (original) one has 5 symbols each line and also 2 lines of manufatured date.
When I check "charge_full" after full charging, it shows 3312000 for the original battery and 3230000 for the new one, while the "charge_full_design" being 3312000 for both battery.

All three batteries I've had showed the same 3312000 charge_full_design. But I'm not sure if this is relevant to us, aside from as a reference to compare to.
Out of curiosity and so I don't purposely give outright bad information, I went and looked at the kernel (up on github courtesy of lunar-kernels).
3300mah design capacity is set when the kernel is built (BLT34 battery profile, which is grabbed by the power manager).
I'm not sure where the number "3312000" specifically is coming from. I can't read the source for the BMS well enough to tell why it's coming up with that number, aside from it's a calculated result based on more than just the design capacity.
Based on the above and other behavior, I don't think any permanent information is stored with or retrieved from the battery itself; design parameters are set in the BLT34 profile and then the BMS amends certain things as it takes measurements. It assumes that whatever attached battery is actually 3300/3312mah until proven otherwise (calibrated with sufficient cycling).
Said measurements are stored ~somewhere~ outside of the ROM, recovery and download mode - mine persisted through the LAFsploit process and TWRP on both partitions - and cleared when power is lost. Maybe they're stored in RAM somewhere? Maybe the BMS notices the discontinuity in power and assumes a battery change, resetting everything? I'll try making sense of the kernel source to see...
The labeling difference is curious, and something I hadn't really given thought to. The newer ones have NOM and NYCE marks, which are Mexican safety approval things. It's interesting that the originals don't have them; maybe because LG doesn't make phones for the Mexican market and thus saw no need? I doubt these third-party manufacturers have gone out of their way to actually obtain said approval...probably just stuck them there to satisfy customs.
I bought a battery from another seller and installed it this weekend; it uses the 12-symbol style as well, has date+date code like the original (dated a rather shiny 2019.09.08!), and weighs the expected 48g/has an OE-style "stepped" back making it thicker.
Seems to charge fully and otherwise work as expected. charge_full still = charge_full_design, I'm not sure if this is because the BMS has determined that it's an OEM-capacity battery, or it hasn't cycled sufficiently to update. Gonna keep an eye on it. Pictures attached.
Edit: battery listing on ebay. Note if anyone else buys it: the suction cup that came with mine was 100% useless. Plan accordingly.
-
A further note on the smaller battery I bought: it did perform admirably. It had no issues when using the phone as a power supply (~2.5A sustained output), right down to where I stopped it at 5%, which is rather abusive for cells in this form-factor. It was just...well...smaller. It certainly wasn't a bad battery at all, it was just misrepresented. Lighter/slightly-smaller batteries would make great travel batteries, if the V30 were swap-friendly...

@Septfox
I hope you bought a good one.
The battery I bought lasts long, but also takes long to charge (about 2 hours). The phone shows fast-charging but when I check battery log in Hidden menu, it shows only Quick charge 2.0.
I found a way to reset the battery information, hopefully sellers don't use this to reset the cycle count.
There's a thread on xda that shows a method to reset battery information on HTC phones. That is holding down 2 volume buttons + power button (volume down + power for LG V30) in 2 minutes while the phone is being charged, let the phone restart as many times it takes in 2 minutes. And then charge the phone to full.
I did that and when I check in Hidden menu, the battery information was resetted to 3312000 full capacity and 0 cycle count.

QC 3.0 wouldn't outright increase the speed any; it exists to help reduce heat and provide more consistent charging.
If it makes you feel any better, mine is also getting stuck on QC 2.0. Judging by the way the Parallel Charging status flickers on and off as I move the cable and put pressure on the connector, I could probably stand to get a new charging port...
This is why wireless charging is a good idea. But now that I think about it, replacement boards are cheap on ebay ($5), so replacing it each time the battery is changed might be a good bit of cheap maintenance to do :good:
Have you tried a different cable and/or charger to see if your charging improves? Maybe you need a new port, too.

I find this slightly alarming, actually...
The normal button combination to hard-reset the phone is power+vol down. This might just be what's happening, and by making the phone do it repeatedly, the firmware might be interpreting it as a bootloop condition caused by something in memory and completely disconnecting power in an attempt to mitigate it (clearing the battery stats in the process). Probably harmless though.
Dunno that a seller would bother trying it, though. What do they get out of it, other than a seemingly-new battery with less capacity than it should have? It would just recalibrate when charged and show the real capacity in the hidden menu, and the game would be up :v

All V30 always show QuickCharge 2.0 in Nougat as well as Oreo. Not sure about Pie.
Speculation was it was a script error, that it was really 3.0 -- but falsely shows 2.0.
Can't remember if it was ever proven one way or the other.
I do remember people say it now charges slower on Pie. Again speculative because LG knows batteries are older?
I'm still on rooted Oreo, so I don't care.

I read "the display may not be correct, so you should totally use this as an excuse to get a newer charger-doctor that supports QC".

Or to mitigate further aging by reducing internal heat. I also remember seeing somewhere that it was limited to 12w or 13w, now that you mention it, though that might have been for 15w wireless which has a reputation for slow-cooking the battery (in any phone, not just the V30).
Hello team
I'm coming with a question regarding the battery of the nubia read magic 5S.
I have been with the phone for less than one week and I am checking that the battery capacity is not the same as the one that is stated by Nubia. It should be 4500 mah but I have 4000 according to the accu battery app.
Can someone please double check this capacity in your phones?
Thanks

the Capaacity on mine is quite good. i think less than 3% when full its 4370mah or around that the last time i checked.
its possible you've charged it at poor intervals. and maybe used a speed charger of some kind.
for the health of the battery and to test. do this for the next 3 or so days.
during the day try to get the phone to around 5% (no lower than 3%) try not to do this fast like with gaming heavy or whatever.
then connect to a slow charger 2 or 3 amps max. and allow to charge to 100% without using the phone. allow 10 minutes grace time after the phone is fully charged to allow the battery to cool a little.
then again use the phone as you would, up to 5% again. and repeat the process 3 times. then check your capacity. that will be your real capacity. if you follow those steps exactly.

Thanks for your feedback. You are kind of right about the fast charger. I iused the 65w PD usb of my Lenovo laptop which really charged the device at full speed.
I will post my results as soon as I can

I have done 3 slow charge discharge intervals and the data in the accu battery app remains that same
Actually maybe the battery is not damage cause the cycle is kind of good. Just trying to figure out what is the issue

it may be best then to contact nubia or the seller you bought the phone from. if the battery is faulty or old is should be replaced. its very odd that the battery is not the rated 4400mah especially for a device that is just new. a small discrepancy like mine 2-3% is usually alright for something left in storage for 2-3 months after manufacture. but if you're past a large amount of capacity in such a short time, its possible that the battery is faulty and will need to be replaced.
do try other battery monitor apps incase your app is giving false readings. But I would contact Nubia about a warranty repair. if you bought it directly from Nubia, @JerryYin may be able to help forward your request.

Hey guys,
Long time accubattery user here.
You'll have to uninstall the app and re-install it before trying the above.
The estimates are not great for long term information but benefit more over long term (months).
If you want a fast reading, try the above but also check your estimated capacity on the main screen (charging), go to the bottom and you'll see it there. Make sure your phone is fully charged first.
My estimated capacity was 4000mah originally, but now I'm showing 4545mah (on the 5G, not 5S).
