hello friends ,i got a new battery (it seems original) and installed it but i have weird problems with the percentage that the phone shows .
-the battery lasts for 9h sot even with some benchmarks on latest pie ob ,so its definitely not bad
-the problem is that when it gets to 10% then it goes 9 8 7.. till 0% in about 5 minutes and then shuts off with a dead battery screen .
-i noticed that the phone still charges when it reaches 100% charges at 1 amp and gets to 0 amps after 20 minutes ,i also noticed that the idle/screen off drain is very very low ,it probably has to do something with the battery calibration
i tried:
going full stock with stock recovery but the issue persists,
doing some all night power off charges to 100%
searched most of the threads everywhere ,but no one has an exact answer .
is there any way i can access the discharging algorithm so i can tweak it ,or if is a way to teach it be more precise?
thanks so much for everyone willing to help ,sory for the long post ,i wanted to be as precise as possible i can provide everything you ask for to fix it .
p.s. i study electrical engineering so be free to use scientific terms.

Not a solution, but just keep the battery level above 10%
9h sot is very good with a battery you don't know if it's original or not

it was 9 sot hours with 3 hours of geekbench battery test (about 14%/hour lost) without any tweaks at all , completely stock ... that's the reason i am trying to fix this issue,the performance is insane ..(every calibration app shows at least 99% health,it even recharges way faster that the old one ,3.8A 10 to 100 in 45 minutes) if it wasn't that i would swap it back with the stock ..

Technically you want to avoid the battery dropping below 20% anyway (If you believe the words from Samsung) so it shouldn't really be an issue.
One thing you can try though is to install L Speed from the play store (require root) and use the battery calibration tool to see if that helps. Outside of this I cant really think of any thing else other than to just deal with it as is.
i figured it out guys...the thermistor in the battery was dead , i though a solution for anyone face the same problem ,desolder the control board from the original battery then solder it to the new one ,the cells are healthier so the battery will be good as new ?

I am creating this thread after exploring the options documented in other similar threads, where I have posted the same issue.
My original battery was weak and I got a new one for my Defy green lens.
I saw that the phone stays at 1% for a long time and then tried several of the tools which remove the battery stats and claim to re-calibrate the battery.
After several such cycles of full 100% charge and discharge till power-off, the phone's standby time has exceeded 2.5 days - out of which it remains at 1% for almost one full day.
Note: I am running Quarx's 4.4.4 nightly.
What are the other things I can try? The phone is used only as standby so I don't mind wiping it off completely and putting stock ROM and observe again.

Dont worry . this happens to me also.. im too bought a battery of 600rs from ebay and battery stays 1 % for a day...
For an investigation i checked the battery voltage (at 100% charge voltage will be 4.2) when it drops to 1%, its nearly 3.9 and phone will keep working till voltage reduces to 3.5... im getting 2 days minimum backup of moderate use...
now to explain why 1% , this is an answer i gt from FB group .. "dnt expect Original battery at 600rs wen its actually cost 1200rs, they are actually replica of real and the so battery circuit send false info to phone, and phone calculates percentage remaining on this "
i tried to switch some cm7 version but in all battery drop at 1% happens.... so i ignored it and my defy still rocks in daily usage after 3 years ...

I find it odd that this is not an original battery.
The battery charge is pretty good - more than 50 hours - no usage of the phone - but poor 2G connection/ weak signal.
I can contact the ebay vendor if that is the case, but I need to be sure first.
I have now put my original battery and I will see if it drains off in the same way or not.

I paid Rs. 600.
I put my original battery (3 year old) and that does not show the 1% issue, though the battery life is less than 2 days on it in standby mode.

Hello guys ive been reading tips about battery lately but i haven't decide what is best for it. My note 4 i still have it , i charge it very very randomly , after 1year i still have 1 day of battery so i didn't do anything bad to it even if i charged it so randomly . There are alot of informations on forums that say that battery should be charged from 30-50 too 70-90 and once a month , u let it completly drain ( till the phone shuts down itself ) for recalibration . I usualy charge my s6 from 20 to 100% , but ive read that this is bad too. I don't know what to think about it and i would like some other people to tell me how they are charging it . Sorry for my english.
It's all rubbish.
It's a battery, it'll have 3 pins, a positive, a negative and a thermistor pin, that's it, there are no electronics inside the battery, it's just a simple chemical Li-Ion battery. I expect when the phone dies at 0% this isn't actually 0% at all, more a feature in software to make sure the battery doesn't get damaged. There is no such thing as 'calibration'.
Do some reading on Litherion Ion cells and you'll see just how much rubbish is scattered by people on here.
Yeah, like the old not leaving it plugged in overnight myth. I've lost count of the times I've seen that one.
To be honest with you , i don't believe everything i read about batteries and im sure im not going to drain the battery once a month just for the fun of it. Still , i am going to charge it to full every time because its easy for me to plug it in and let it sit like 2hrs and get it full than to watch over it and stop it from charging at 80% , when its green,i take itoff and that's it.
One thing to note though, which is true, is don't ever leave a flat battery flat for a long period of time as this will reduce its efficiency in the long run.
Noted. So , one more thing , what should we do , charge from 20-30 or whatever to FULL or to 80% as they say it's not OK to go full.

Well , samsung reply was satisfying . So i guess if someone would really want to care about the battery lifespan , should discharge phone ( till it shutdown itself ) and recharge from time to time (1 /month ) .
Samsung reply with :
" Regarding the charging of your device, all of the scenarios you describe shouldn't have any particular negative affect on your battery. However, completely discharging a battery from time to time can help to extend its operational life by a small amount. "
( The scenearios i described are the same as in the first post of this thread )
I will try install many roms and in all the battery life is bad.
CloudyG2 3.3 and 2.2 and more...
What can I do? I have LG G2 two years.

Remove all apps you don't need. Install wakelock detector to see what is consuming battery on your device Then disable them using greenify or servicely . You can also run this script http://forum.xda-developers.com/lg-g2/general/guide-reducing-google-play-services-t3139032 .
Remove extra bloatware , avoid using wifi , reduce screen brightness .. or go back to kitkat.
I would rather suggest to change your battery dude, 2 years for a mobile battery is more than enough.
Only apps was installed on my device is WhatsApp, facebook, Instagram and Greenify.
Yesterday I downgrade to KitKat and the battery very bad (Cloudy 2.2)
Same problem here : http://forum.xda-developers.com/lg-g2/help/lg-g2-d802-battery-draining-5-0-2-t3256313/
I also got bad battery life with all LG lollipop rom and stock kitkat , but I get terrific battery life with cloudy g2 2.2. Like 6.5 hours of SOT. Just make sure you clean flash and reduce background app by clearing recent apps.
Are there any apps that show the battery Wear level

6.5 hours?!?! Are you sure?
1.5 to 2 hours of SOT is the most I can get out of my two-week-old G2.
I bought is from a "mobile shop" on aliexpress.
Yes, it is refurbished... ,it looked like brand new on the outside.
... however, when I disconnect it from the charger in the morning (7 am) a few hours, and a few phone calls later it is already at 85%
at noon there is 65% left.
at the evening - somewhere around 22h - the battery usually dies completely ...
14-15 hours of usage on battery... NO games, NO Youtube videos.
Max 30 minutes browsing the news (on WiFi)... and an hour of phone calls (city center, so no problem with reception...)
When the screen is on (btw. I set it to 70% brightness) I can literally see the battery percentage indicator decrease every few minutes...
Looks like I got a phone with bad battery... didn't I?
I'm on KitKat (4.4.2 stock) D802 version...
I had this problem on my freedompop(sprint) "refurbished" phone. Even though it looked like new on the outside, I would only get 2-3hrs sot. After replacing the battery I now get more than double that. Factory reset, disable/uninstall the apps you don't need, and only install the apps you do need. If you still get bad battery life then the only option is a new battery.
Btw, a custom rom will NOT give you significantly better sot unless it severely cuts performance and lcd brightness.

Well if you are using kitkat then i must say you got a faulty or old old battery . G2 on kitkat is/was a beast , I can recall those days when i used to get 7+ hrs sot on kitkat . you should call or email to your seller and tell them the problem you are facing.
After sorting through potential power draining apps etc.. You could try a battery calibrator of some sort. I used one and a big difference noticed, however after it's fully charged in the morning I take it off the charger and leave it sit there for at least 30 mins without touching it and battery life is even better.
Thank you all for your answers.
In the mean time I installed this Battery Monitor Widget.... and it gives me some "interesting" readings:
1. my phone charges ridiculously fast. From 37% to 100% in 70-80 minutes... Connected to the charger at 00:04. At 01:14 it was already at 99% (This widget gathers info every 10 minutes)
https://goo.gl/photos/DDerdsk2mSdKipMt7
...and it charges with an insane amount of current (over 2100 mA)
https://goo.gl/photos/VJd7iUFMm5A4s3UeA
2. there are some kind of "spikes" in battery usage, but after a few minutes the battery seems to recover...
this is the battery voltage statistics:
https://goo.gl/photos/Uh96utz1aBJNV3qCA
So, It is more and more evident, I got a faulty battery...
Now, only if I could know where to buy a GENUINE LG battery...
Aliexpress is full of "shops" claiming they are selling "original" LG batteries, however there are quite a few negative reviews about them... (batteries are lighter, thinner, deteriorating fast... etc.)
I think I am the only one whose half, more than half battery drains by #screen only?? I have googled many times and applied all those tips but didnt work I use my phone in 0 brightness and the screen timeout is also 5 sec and even in reading mode. But battry drains so fast, It decreases #2% of charge in #3 minutes. Please help me to fix this.. PH Model: I9505 XXUGNH6!
-Thank you.
How old is your battery?

Completely normal. The screen uses power. If you want it to drain less, then leave the screen off.
It's normal...
Check whether your battery is swollen or not. I just replaced mine yesterday. Before that my battery usage due to screen was pretty high and now its about 16%. I assume that you are not using extra display features.
All the best!
My battry.. Its around 8 month old #GDReaper
#Mandark52, Its not swollen anywhere. AND I am also planning to get another one
#No_offence!! But I dont think 60% by screen is not normal..

Sure it's normal. You are running Kitkat thus that means the battery usages is calculated in the following way.
If your battery is at 90% then for example it will show you this:
- Screen 90 %
- Android OS 10 %
It's calculated of the the missing 10%.
The screen uses a lot of power so if you have it on all the time then 60% perfectly normal. Based on your 2% discharge in 3 minutes it will be around 2,5 hours of screen on time. That's perfectly normal for the S4. Nothing wrong with your phone. The battery life of the S4 just sucks.
Hehe. If so ok but will this improve if i purchase new battry??

My SOT now is 3hrs 52 mins and my battery is 18% .
Remove the bloody screen and then check how much the battery works.
Obv the SCREEN TAKES UP MOST OF THE BATTERY. 60% is fine.
Rest..you can do ATM is use a good debloated custom ROM, use better battery saving techniques than just screen and stuff and tell us uour SCREEN ON TIME.
My screen is taking upto 50%.
Dont hype. Stay calm. A new battery wont do much good.
Hehe.. okok now I am feeling good cuz others like you also have 50+ means mine also normal haha.. ??
Hello everyone.
(Please excuse my lengthy post, I had a lot of details to share. Thanks!)
So I recently bought N910C from a guy in Dubai, who gave me an extended 8500mah battery along with it, and claimed that it would last me 3 days easily (though later he claimed that it runs a day on full use, and 2 days no mild usage. Also claimed that standard 3220mah battery lasts less than 6 hours) but 8500mah would take around 6 hours to charge (it takes me 1.5 max, does 1% in a minute, with quick charger). I was however instructed to calibrate the battery properly, which I did, twice, tried the manual (draining and full charging) method, and also tried two apps: Battery Calibration and Battery HD.
Facts:
After buying, I flashed marshmallow stock rom for N910C and rooted with CF-Autoroot.
I have been using its own fast charger throughout, not the standard charger.
Here is the problem:
Before rooting and changing the rom, the battery was barely lasting and would shut down when around 30%. So I rooted the phone and did the calibration (manual+Battery calibration app), but the battery timing remained the same, or maybe increased slightly. The good thing was that it did not shut down at 30% and went down to 1%, where it stuck for good 15 minutes (with me browsing the net).
After I recharged it, I tried Battery HD app, which ran tests and gave me the following figures of battery usage:
30 minutes on internet: 5%
30 minutes on video: 6%
30 minutes on music: 2%
After this process, the battery again collapsed in its 30s%. I tried the battery calibration method again, but no luck now, battery collapses in its 30s. The guy who I purchased it from keeps sharing the snapshot and claims it was working fine before.
Now my questions:
I read some guides, including topics on XDA that suggested that Exynos drains more than snapdragon. So should I try to make a switch to a variant of note 4 with snapdragon, or would that make no major difference?
Is this battery faulty and I should change it? the Seller claims that he had to come on to an extended battery cause the standard was ****, so I shouldn't try and get another, it would be a waste.
What could be the problem if the battery falls in 30s% even after calibration, with exception to that one time?
Also, when it collapses in its 30s and I put it to charge, the screen shows "charging at 45%", why is that?
Lastly, I read here on xda that zerolemon extended batteries require the standard charger as the quick charger would give **** time and would charge them quickly. Will that apply to me as well? Although my battery isn't zerolemon, it's some unknown brand. And it seemingly charges quite quickly with the regular charger as well (when the phone is turned off).
He claimed that it should take my phone 6 hours to charge, it takes me barely 1.5 hours even on the extended battery, is there something I am doing wrong?
If you went through all of what I wrote, thank you for being so patient! So now, do I have any hope with this phone or should I just sell it off and maybe get an AT&T or T-mobile variant?
Thanks in advance for the guidance to come. I'll keep updating this post with whatever other tests I run, and the progress.
