[Q] ROM's are p1ssing me off

I have tried just about EVERY ROM. And I still am only getting around 6 hours of battery life. Is it the ROM, the dumbass user (me), or something else. I keep hearing the fantasy stories of people getting 15 hours on battery while using the phone all day long. Can someone point me in the right direction as far as ROM / Kernel combo that truly does this? Currently on the latest CM7 Nightly and don't like it at all.

I've been having the same problem lol. I'm currently on MIUI 1.9.23 and using Trinity ELP kernel.
I've had it on for about 6 hours and I'm down to 65%. I mean it's not terrible, but considering the phone was in airplane mode for 1.5 hours of that 6 hours, essentially the phone has really only truly been on for 4.5 hours. so I'm losing about 9%/hour.
I've literally tried everything I can to increase battery life but it just won't happen. Let me know if you figure anything out.

Hey you know I have had this phone for about a week, and I have tried all these roms on here and to be honest, the only one that does what I need it to do is the tweaked OTA version. As long as I have root and rom manager I am good. My Battery on any device does not last as long people say. So many things have to be considered. Like whether i am moving into 2g networks or how much i am using it.
The best thing for a battery though is to over charge it for an extra bit and then reset the stats. After dont recharge till it turns off by itself. Then do another over charge.

So by overcharging you mean leave it plugged in even after it says unplug it to conserve battery life

Yeah, when its plugged in it will charge continually and making sure its really fully charged.
I noticed this with my Milestone2, it would say done charging and it wouldnt last very long. So I read up on Battery charging and it said you should leave it charged for an extra hour or so. Only when trying to reach full battery stats.
Of course its ok to use it whenever but once in a while you should do a full drain and then full charge

Plus, most of the people prob on here and doing everything under the sun to thier phones to tweak them. That could be a big reason why the batteries arent lasting so long.
Today I went through 3 different rom changes while at work (3 hours). After finally getting it back to where I was before work, my battery was at 23 percent!

Buy an extended battery off ebay or amazon for around 9-12$ Stock battery i can sometimes get about 12 hours depending on what i use my phone that day. But those 3500mah batteries should at least get you 18-24hrs for sure. Just make sure you cycle thru the battery a few times so it can start performing it's best.

Just put the Miui Rom on. Noiw am getting hang ups in Market on Wifi. I go to download something and it just sits there at starting download Any thought on how I can remedy this issue?
Arrgh...would have been nice if T-Mo and LG had put a working product out to begin with LOL!

It would be helpful to see your battery usage screen. I'll paste mine below. I'm also on CM7 (recent nightly) and I get good battery life IMO. Right now I'm at 8+ hours and I still have 76% left, but I've been at work all day so I've only used it for a few texts and calls and some brief web browsing. Typically I'm a very heavy user, always on, and with the stock battery and that kind of usage I only get 5-6 hours. I have a 4500mah battery and with that I can get up to 2 days of my normal heavy usage with that battery. It just looks like a brick and some people don't like that.
Are you a very heavy user? If so and your phone is constantly on then 6 hours may be all you can get. I think some of the claims people make are a bit misleading because there are so many factors that will influence your battery life.
Here's my screenshot.

You should give miui another go with stock kernel and setcpu screen off profile, i get pretty good life.
X

Disable bluetooth, disable GPS, and turn the screen brightness to 0% lol

@ phBurks, I am a very heavy user, Constantly relying on GPS as well as phone and mail since I am on the road all day long. I was hoping for better battery life. May have to get one of those extended batteries mentioned above.
@fcisco13 I'll give Miui another go. Where do I get setcpu? If its in the market I am hosed LOL. Market is hanging up on me all of the time.
And I cannot see any of my APN settings no matter what ROM I use.

Based on my own person experience the only way to get +8hrs is if I'm on WiFi. On cellular....forget it.

Minimum for me on MIUI is 12 hours... With a good amount of usage, and HSPA+... I use SetCPU though, it helps alot. Best application for saving battery life IMO.

You may be able to squeeze out a couple more hours if you use setcpu (from the Market lol). My suggestion though, if you're that heavy of a user, is you'll either need to keep your phone charging in the car (make sure you have at least a 1amp charger ... I use a 2amp charger in my car to make sure its charging at its max rate), or buy an extended life battery. I recommend the extended battery. There's a 3500mah one over in the accessories section that's pretty cheap and sounds like it works pretty well. I have the 4500mah one from Mugen Power. Its a little more costly but it also lasts a few hours longer than the 3500mah one.

+1 Especially if your kernel supports undervolting, i can successfully uv -100 up to 1100mhz, i rarely need to go over that speed anyways and know i can get a crazy high quadrant score if i overclocked anyways. Settings i have righ tnow for setcpu are:
222mhz - 100 uv
up to 819mhz -100uv
Gets me easily 6-10hrs with lots of usageon stock battery.

It varies. I find that using a CM7 cooked ROM have terrible battery life. I'm sorry, just from my personal experience. Only other app that kills the battery is the GPS.
A Stock Cooked ROM gave me fantastic battery life. But.... its stock, and some things in Stock just can't stand. Also, had random reboots. Maybe I messed around with too much crap in my SD Card. Who knows. If I really wanted to, I could make a ROM stable on my phone. But just can't stand the Stock ROM.
Stock 2.3.3 = 15 hours moderate use
CM 2.3.5 = 8 hours moderate use
Regardless, if you want a long lasting battery, don't get an android. No phone is perfect. Only my battery extender 3500mha but I end up with a PHAT Phone. Plus its not protected by my rubber case.
Thats the only reason I don't use the battery extender.

After completely wiping my phone and installing whitehawkx celebration MIUI 1.9.23 I get awesome battery life. I think before since you had to "hack" 3G to get it working on whitehawkx MIUI was why it wasn't working great.
I'm on the whitehawkx kernel that comes with miui, whichever one that is. I'm going to give trinity a try. Then again, I have no apps installed except for facebook with notifications off and auto-sync off. But good news is my phone is not constantly awake now.

Give Eagleblood 2.3.3 1.07 a try, good battery life with its own kernel. I tried with Faux GB kernel gave me random SOD, and reboot, also took way too long to boot too.

Just installed this ROM. Will report back later what the results are. So far so good.
Does anyone know of a good clock / weather widget that doesn't use too much battery life?

Radio battery usage.

Can someone please explain this to me, or help me understand this. My battery drops like crazy all the time. Last night I fully charged, cleared stats, fully charged again, pulled the battery, restarted and left sitting in an area of my house with good coverage. This is what I wake up to.

20% drain. Go to the settings and look at what's been eating the battery. Roughly 10% of my battery was consumed by the radio. But, it only shows 2% of the time without signal.
I have os monitor installed. Is there a way to have it record consumption, etc while the screen is off? Or is there another option you guys know of.

I had the same issue a while back. My phone was dying in 3 to 4 hours with no use. What mine turned out to be was something got screwed up installing a new rom. After that no matter what I flashed nothing changed. Sense, aosp. It didn't matter.
When mine did this I also had trouble even receiving phone calls as well as making them. I would get the call but then there would be no sound whatsoever. Are you having that issue as well?
Anyway the only thing that fixed it for me was to ruu back to stock and then re root. I wouldn't jump to that conclusion yet especially if your not having the same issues I did but I do feel your pain. Good luck

Iwould try flashing a different Rom. Have you updated your radios? If not I would. But definately try a different Rom. Also be very sure to Clear your device properly before a flash. If not it can cause a lot of strange issues.

I use clockwork. When I install a new rom I reset in fastboot, do the same in recovery, wipe cache, then I go to advanced and format cache, dalvik, sd-ext, and system. I think that's all of them. Basicly anything listed anywhere in the recovery that wipes/formats anything but the fat32 portion of my card. Then install. The exception to this is with cm7 anf new nightlies. Then I wipe cache and dalvik. Then install the nightly over the existing install. I never use rom manager to flash anything. Nor do I use kernel manager to install new kernels. I have installed the new radio and wimax although I'll never see 4G around here.
I guess I may do the ruu thing. That sucks.
Also, I've noticed when I fully charge, regardless if I unplug it as soon as it reaches 100% or let it sit for a while longer, when I unplug it the phone drops to 96% or so like hella fast.
I have also considered I may just have a bad battery now.

If you suspect the battery you can always AnTuTu Tester to check the battery. If it is the battery you can always go to your local Sprint store and ask them to exchange yours.

Cool. Thanks bro. Downloading now. They will just swap batteries?
Sent from my PG06100 using xda premium

They will do a short test on the battery. Then most likely switch it out, free of charge. They've done this for me several times.

I'm having the same problem with my wife's shift.
She told me a week ago the battery started draining like crazy overnight, like 60% drop without wifi or 3g turned on.
I have ss8 with dodgekernel and latest radio 1.08
I looked at it and thought maybe a problem with apps, so I put autostarts app on to kill unnecessary apps.
This still didn't fix it.
Also traded batteries, also no fix.
I unrooted and brought to sprint.
They couldn't figure it out and told me to update to 2.3 and if the problem is still there to bring it back for a replacement.
I'll do that and let you guys know.
Right now it's running fresh and the problem is still there.
The signal cuts out completely every 30 sec. or so no matter if it's full signal or not.

i tried the app mentioned. it drained the battery to like 20% before stopping. it rated it a 548 i thing. it places it above the incredible. not really what i thought the test would show.
right now i'm running the nocturnal rom for a while. i'm going to see how it does tonight before adding any of my usual cast of apps. i figure the best test i can do is to let it run naked and see how the drainage is. i plan on having it at 100% and let it sit for 6-8 hours.
tomorrow i'll ad my most important apps and make sure their notification stuff is turned off. this list of apps includes weatherbug paid, dropbox, teamviewer, text editor, andexplorer, and andftp. weatherbug it the only one that runs the backgound updates. i have it set to refresh every 4 hours and have all the other updates/notifications/alerts turned off.

Updating ( downgrading ) to 2.3 Factory Stock GB will not resolve the issue. As for Autostarts App, it's kind of like a Task Killer. Which have been proven to use more battery and CPU then they save. When you went to Sprint and they gave you a "new" battery. Did the guy go in the back and bring one out? Or did he just hand you a new one in the package? There's a reason I'm asking. I went to Sprint 3x's and they gave me "new" batteries. But it wasn't until I refused the one handed to me opened, and insisted on an unopened packege that I believe I truely received a new battery. I watched that day as they exchanged several batteries for customers. Everytime the employees would go to the back desk, put down the battery they had in their hand and just grab one off the desk. Which was one someone else had bought in obviously for an exchange . That is why I demanded a new one in the package. Also the Stock Factory GB release is plagued with annoying Not a batch restore, or a restore with TB. Just to make sure it's not a rogue app.

As a rule of thumb when you do a fresh flash. You should let it settle for several hours before installing any apps. When you do reinstall apps, try not to restore data if at all possible. Lastly try to install apps one t a time. That way you know how they're doing with your setup, and if there's an issue. If there is it's alot easier to track down.

Yeah I noticed the tech at the store was at a loss for words when I told him it's not the software but he insisted that I update to 2.3 before they gimme a new shift.
Also, for the battery I just put my battery in her phone which gives me about 24hrs heavy use on ss8. And only about a 2% bat drain overnight on mine.
This obviously did not solve the issue.
I'm convinced it's the hardware, just gotta update to 2.3 before they swap it out.
It's just a huge inconvenience since the only sprint retailer is 30 min. away and last time I waited 3 hours for them to shrug their shoulders at me.
thanks for the advice though, I'll keep that in mind

When all else fails RUU 2.2 and/or call sprint.
If you have to RUU to 2.3 to get a new phone do it. It's better than going through Asurion.

[Q] Battery Life, Return Or Not?

First off, I am loving the phone. It is such a massive leap from the N1 I had been using. While I expected lower battery life, I did not expect to run through 70% of the battery in 4 hours with moderate usage.

I have heard of people getting far better battery life, and have tried the various methods, from charging to 100% then turning the phone off and charging again to 100%, using juice defender ultimate, and even resorting to factory resetting the phone. Still I can't get any kind of good life out of the battery. My question is should I try and get a full replacement for the phone or just the battery? I've only had it sinceblast Thursday, so I know AT&T will happily exchange it, but if yall think it's just the battery, I'd rather just replace that then the whole phone.

Have you found out what is using your battery?.. Even before I rooted and all the other stuff was getting at least 10hr.. now Im getting 24-28hours...
Are you running another ROM other than stock?

Didn't want to root if I needed to return anything, so I am running stock currently. Looking no app seems to be running away and draining all the battery. Everything looks the same as it did on my N1 in terms of what's draining the battery, which is what lead me to believe it's a bad battery possibly.

Return it for another.. This is a great phone!!!

definitely return it.

Well if you do root than TPC's Rom is the best. It comes with kernel and the battery life is outstanding.

I was concerned with battery life at first as well. When I first got this thing I had to plug up 9 hours after I unplugged. So now I am near 30 days with it and the battery seems to have leveled out enough for me to be happy. I got 16 hours on it STOCK no ROOT the other day without plugging in, was at 10% when I finally plugged in. Yesterday I activated Juice Defender again after getting some questions answered. I got 17 hours without a plug in and was still at 25%, so i probably could have gotten 20+ hours if I needed it.
So I am happy now 17+ hours is plenty long enough for me, I always plug in at bedtime anyway.

I'm wondering how many people who are reporting battery issues, if they have calibrated them. Charge your battery all the way, use the phone until the battery dies, then fully charge. This will give a more accurate reading as far percentage used.

There is a new ROM Piret RC1, the battery life is amazing, it has a different Kernel as the one with TPC has it';s problems.
RC1 is clean fast and in 2 hours I used up 4%. Then turned every possible service on used it up like crazy to drain the battery, installing/backing up/ flashing new rom and it took 2 hours with heavy usage to drain from 17%. Just to compare last night I had a TPC ROM and was on WhatsApp for about an Hour and battery went from 85 to 34 %.
Re: Returning the phone.
First once you root you can the same way unroot, make sure first you install a stock ROM.
My friends have the same problem, one with this phone, and others with android phones in general, don;t waist your time returnig. To be safe you also have a year to send it to Samsung to get fixed if there is something wrong with it.
Basically, running apps will kill battery, location services kills it the most, sync not so much, heavy use of data does to (I have LTE plan). Use power saver to start at 70%, configure it right, use the CPU app to manage the speed ondemand.
Most important don't frick out, the andoid phones are like that, the major difference is that Iphone does maybe 20% of what android phone does in standby and many things are not available on Iphone, so the battery is better. You will not get more then a day of use on android if you use it to your benefit. 28H is mostly standby, no sync, no internet usage, just moderate. I used to use Iphone heavy and battery would not last a day.
Get a good data plan, don;t use WI-Fi unless u have too, when syncing with the car plug it in the charger, spend extra $10 get a Samsung cable from them, don;t go for cheap 10 dollar once or even 1 dollar once from China, they are very slow to charge. My cable from the box take 1.5 H to charge to 100.
Hope it helps, please don;t quote me on anything, this is purely based on research and one week usage and trying different things, it's strictly my opinion, don;t expect your phone to last like they use too, it's 21st century and techno in it is overwhelming and needs power. Keep the phone have two cables and enjoy!

good habit to get into thanks for that....the search button is your friend.

I have been reading on the battery issues, long before I posted. I have done everything from calibrating, to using juice defender ultimate, to doing a ritualistic dance to try and coax more battery life out of this phone. Still with nothing but 2 phone calls and one quick spelling look up, dead within 8 1/2 hours.
I just got my extra battery and charger from samsung in today, already fully charged up this battery and will see what it can do for a few days. I'm hoping my problems are just a random bad battery. I also factory restored and am running bare minimum on apps just to try and remove all variables. If there still is a problem I will exhange it for another one next week. I just hope they still have some white ones in stock

My battery went completely dead too. I returned mine. Black model though. New one is doing okay so far. Better since it doesn't report 100% battery until a reboot...

Finally went and exchanged it last night. So far I have gotten 9 hours of battery life and am only down to 70%. Better than before, but the vertical lines on the screen are worse on this one than the last.

I have almost the opposite "problem." Not that I'd call it a problem just yet. I had my phone running from about 10am till 1am yesterday. I went to bed and plugged the charger in and it instantly said "battery charged 100%. Remove charger." 15 hours with no drain at all? Granted, I didn't do much with it yesterday but send about 20 text messages.

Going on 32 hours+ battery life and no vertical lines.. bought it when it came out Nov6....

30% in 9 hr's? you need to see what is killing your battery... unless you play games or on the net all day.. that is not good at all..
I lose about 1% an hour..

I don't know what you smoking man but i tried his rom and never had issues. Let me tell you I Have ORD so my suggestion will be based on my usage rather than prediction. I have tried most of the themed/tweaked roms. Don't like stock rom.

Considering I used to be lucky to get 10% drain an hour on standby before, the 3% our so i'm losing an hour now is awesome. And in those 9 hours I checked google reader and played some levels of Trial Extreme 2.

[FIX] Battery Drain Issue Solution

I was always having the problem of when I would turn my device off for the night when I turned it on in the morning I would have lost anywhere between 15% and 40% of my battery. The easiest solution (only if I remembered to) was to pull the battery every night after I turned the device off, if I remembered. Well this was an annoyance for both having the battery drain if I forgot and to have to remove the batter every night and then put it back in every morning. I know it seems like I am just complaining with that last statement but I just like to have a phone that just works.
Now, back to the problem. I was always running either a port of MIUI or a CyanogenMod Stable release with both 'stock' kernels or one of faux's for CyanogenMod or morfic's for MIUI (as they got along better for some odd reason). Well, no matter the combination of kernel type (OC, UV, or Stock) I always had the battery drain problem and stability issues (depending). Then when the new baseband was released I installed it after I found out that the CyanogenMod RC3 supported the new baseband to see if that would fix the problem, just it still didn't work even with different kernels.
I was starting to get fed up with these issues so I decided to try one last thing: I used the LG support tool and went back to completely stock! I did root it with SuperOneClick though so I could use all the apps that I was using before (Titanium Backup to restore all of them). I have been running my phone like this for two weeks now and have never once had the battery drain problem. And what is even better is I am getting an average of 40 hours of use out of one charge in and out of WiFi with WiFi calling and 4G when not on WiFi (mind you I am not a really heavy user). I hope this helps!
Well, I know this is a long post but I figured some back story would be good for those to see if you have had the same issues to be able to see if this solution could work for you too. Please click Thanks if this helped you.

So, It sounds like the custom roms issues then. I had the same issues and did evevy thing you have done except using stock rom.

Could you post a picture of your battery usage?

Might have to try that I don't know how long I could stay stock tho

I've had the toughest time with this phone. I originally bought it from a guy off craigslist to replace my wife's MyTouch 3G. It was completely stock when I bought it and after messing around with it for a few hours I decided the phone seemed to be in good working condition. I have plenty of experience rooting/flashing the MyTouch 3G and my Samsung Vibrant and I have never had any problems. So I read around here for the LG G2x and went ahead and rooted it/ flashed ROM and soon after I updated to the newest baseband. I started noticing that the battery drained really quickly, to the point that my wife couldn't use her phone for long. She would play Scramble with Friends for maybe an hour and the phone would be dead. I tried flashing other ROMs to no avail. I went back to stock ROM and unrooted it but the battery still was terrible.
I started thinking maybe it is the battery, so I bought a 3500mAh battery off Amazon, but no luck. I have searched and read many many threads about this phone trying to fix this issue. I've tried downgrading the baseband but was never able to get it done. I'm sorta stumped on what to do next. The phone seems to hold a charge magnificently if nobody uses it lol. I charged the 3500mAh battery to 100% and then I left the phone for 24 hours and it was still at 99%, but as soon as you use the phone it dies quickly. My wife already gave up on the phone and I ended up getting her a Samsung Blaze which has been fantastic. Now I have to fix this phone and sell it or use it myself, but I don't know what to do. Any ideas or detailed instructions? I'm tired of searching for help on this issue, was about to make a new thread about this when I saw your thread.

Stock has good battery life but I actually got the best on EB 2.3.7. Decided I would try an ICS ROM again but it seems they all burn up battery like crazy and there's no way (that I've seen at least) to turn off background data which I've noticed is the biggest culprit as it drains the battery fairly quickly when the phone is idle.

This ROM by BuROM is really good. It's only slightly modded Stock and gets great battery life because of that.
http://forum.xda-developers.com/showthread.php?t=1661610
Another problem may be that you are using different services on the stock kernel. If the battery is draining really fast when there is a network connection then something is probably constantly on the network. I always (meaning sometimes) test ROMs on airplane mode overnight, on WiFi only and on 4G only just to see what their drain times are. The stock kernel is pretty good but the newer CM7 kernels are fine too. I only get about a 1 hour difference after 2 days on a ROM. For some ROMS the first day is horrible as the software is doing all sorts of things. After about 2-3 resets and as many fix permissions it usually settles down into a similar battery drain to the stock kernel.
@Kingfanpaul: If that G2X drains the battery with only BuROM installed and gapps (without any other apps) then it's a hardware problem. I'd NVflash stock, check APN settings and then run it for a day to see what happens.

I have the EXACT same problem. I've already gone through 5 different batteries but still cant manage to get my G2x to last more than 8 hours and thats best case scenario with VERY lite use. Your post is making me think it's these custom roms. Going to try stock 2.3.4 and hopefully I get the same result as you.

What is your screen on time? I'm on latest stock CM7 with stock CM kernel and I get 2+ of screen on time easily with a 1year+ old battery. Battery depends on how you use your phone too. mAh and kernel can only do so much.

Something odd that I have noticed is that while my phone has more consistent battery life, some of the issues that I have had with this phone are due to a bad device. My phone tends to go crazy every so often and just burn through the battery to the point of over heating. From what I can tell this is just a problem at the hardware level with my device, so while sometimes going to back to stock does help the battery if it keeps up it may be more than just the ROM.

Try to turn mobile data off / wifi off ? I have similar problem with battery drain... Right now, at deep sleep the phone sometimes works as expected : 4-7mAh, but sometimes it drains way higher : 20-50mAh.

Not sure my on screen time. I know its definitely less than an hour. I'm averaging about 5 to 6 hours of use. About 20% drain per hour on light/medium use and 10% a hour when idle.

I used to have this issue on my old g2x even on stock roms and it seemed hopeless no matter what I did it came back. Then that phone got run over by a car. The one I have now doesn't have this issue at all on any rom or kernel....well.. almost. Some kernels are sorta battery hungry, but nothing like what I had before.

So you think it just may be a hardware issue? Bad phone?

I guess it's possible. Have you tried a new battery?
Edit: o. I see lol
The things I tried were the nullifier and the other wipe tool who's name escapes me... nvflash based. By mansa_noob. And the day it got ran over I had flashed buru's rom and I was hoping that took care of it but I didn't get the chance to find out.

New battery, 4V reading after 33 minutes of display... WTF

Hello!
As you may guess from the title, I just changed my battery and after having it charged fully I noticed the the voltage reading on CPUZ was 4300+V after many minutes browsing the net over LTE. Although I'm no genius in voltage and stuff, it seemed to me a little strange and I kept tracking the reading. Right now is about 40 minutes that the display is always on and the OS says 100% (I bet it ain't right :good.
Now, may I have broken the SoC while changing the battery so that the reading could be altered? May this new battery have come from the future where it can store enormous amount of charge thanks to alien technology?
HALP I don't want my phone to explode like a Note 7 :crying:
EDIT: the voltage now seems to have increased even though I did not connect it to the AC. Now I am going to sleep, hoping that I do not blow up. Wish me luck.
EDIT 2: Before going to bed I rebooted the phone. After the reboot and around an hour of screen time it has consumed about 33% of the battery (I had those low consumptions only with CyanogenOS 12 LOL). The SO now seems to be reading the battery correctly. What could it be? Still hoping not to burn down during the night... Good night!
EDIT 3: https://goo.gl/wKB4Bs
EDIT 4: That's my actual situation:

This graph shows percentage and voltage of the battery over almost 24h. At first i'm charging, then i use it normally. After many attemps like this one i noticed that the battery life is now normal, but the percentage is still f up. Maxium voltage was around 4.3V, which is fine i guess

Well readings are looks like normal but this is anormal of course. Maybe it is a new battery so it's opening state maybe you need couple cycles to make it adjusted. Is the battery original? And you done all correctly? Maybe clean flash fix it or use it until its dead and recharge while phone off to %100. Keep me updated.

Just do a full discharge-charge cycle and keep it plugged in overnight with a powerful 2A charger. Sounds like your battery needs to recalibrate and that's what this does.

I think it's common bro. No need to worry
I always have that kind of discharge voltage

Thank you all for answering Now let's have an update:

Maybe the voltages are but the percentage is crazy tho!
Now i have few updates:
- if i fully charge the phone, it will keep the reading at 100% until i reboot the phone
- the OS is able to keep track of the consumption until the battery percentage goes below 100%
- rebooting the phone changes the percentage reading always (LOL)
- i did not notice any real increase of the battery life compared to the previous stock battery
Here 3 screens i've done, the first two are from yesterday after the first full charge, the last one has been shot right now. and the phone got detached from charging around 11:00.
The mystery deepens....
EDIT: Just rebooted, 70% battery displayed from 100% rapidly decreasing

Still sounds very strange. I suggest you to go FULLY stock(like out of the box stock) and then use it with stock firmware for a time. Maybe it helps..

I hate stock ROM, i'd rather replace back the stock battery instead. Putting aside personal preferences on ROMs, how can changing ROM alter the reading of the battery? I mean, it does depend only on the voltmeter reading, and that's HW. Are there different ways to interpret the voltage reading? If so, i'd like to see some examples. Just curiosity

yes it is up to voltmeter but voltremeter sends its readings TO the software and i think there is a somekind of cache. And when you unplugged the old battery and replace the new one it might corrupted the reading. But on the other hand replaceable battery phones can do this switch w/o problem. Maybe there is something special or additional thing going on there. And not flashing any other rom but going back fully stock might be the right solution for you because it flashes and deletes everything. Resets everything. After that reset you might as well flash twrp again and flash custom rom again. But maybe theese all just an theory and going back to stock will not help. Maybe only faulty thing is battery but you wont lose anything with trying. As long as you backup your data

I went back to stock (still unlocked bootloader tho) and fully discharged the device then fully charged. Now, at 100% reading i unplugged the phone and started an AnTuTu benchmark to see what happens. Again it was still showing 100% after 2 full tests (the device was crazy hot on the camera, i know it's normal) so i rebooted. After the first reboot was still 100%, after a second reboot it showed 89%. Let's keep testing... Any idea? @zaoms

Hmmm, if you even went back to stock and that not helped i am really thinking your battery is faulty. Have you ever watched oneplus one battery replacement videos on youtube to see if you really done it properly?

Actually now, around 50%, it started behaving normally I think that the stock "needed time" to recalibrate. Rebooting now seems to not giving any problem and the discharge time seems to be reasonable. Now i am flashing back Sultan, let's hope!
By the way i followed the ifixt guide here

well great then! i assume something has been ressetted when you went back to stock and now it collecting data from your battery or something. And put this things together it starts to behaving normally. I hope it continues like that:good:

It's because of sultan's battery driver. He has changed some voltage thingy (AICL, remember @zaoms). But I'd suggest you to flash another ROM like LineageOS to check if it's the same as stock COS in terms of battery "calibration". Let me know what happens.

The mistery deepens even moar... I'll try as soon as i can but i need a stable ROM right now because i have an exam tomorrow and i need to prepare my cheating table for phone and weareable xD
I'll try tomorrow tho, thank you guys ^^

After few days of testing I'm back!
I'm using the stock rom for a while now and unfortunately the battery has not "calibrated" or whatsoever. Nevertheless i've found a pattern in the battery readings fluctuations. Here's the roll:
1) battery completely discharged
2) charge while turned off until it says 100%
3) turn on the phone, it will now say 88-92%, let it charge until 100%
4) reboot and hope it still says 100%, otherwise go back to point 3
5) use the phone until it powers off by itself
6) turn it back on and it will say something like 60-70% remained battery
7) use the phone until it powers off by it self
8) turn it back on and it will say something like 10-70% remained battery or be really discharged
- if still charged use it until it's really discharged
That's how a battery cycle goes right now with stock OS and unlocked bootloader (just fyi). Any idea of the reason behind this abnormal behavior?
Curiously, when try to turn on the phone in the end it vibrates, does not turn on and does not shows the low battery warning, why?
I'd like to point out that sometimes the reading of the voltage of the battery increases for a moment then goes back to normality while discharging (is this magic?).

Update: i was charging the phone while turned off from 0% and it showed to me the low battery sign., after a while it started charging apparently correctly.
Now after 1h the phone was showing 100%, i detached from the AC then connected again and it showed 100% but started to decrease the charge until 68% then again started charging. LOL

Update: seems like i've get what's not working!
What is broken right now is the charging: the phone is not able to understand how to charge the battery fully. Right now i've found a workround:
- turn off the phone and connect to charge
- wait until you see 100%
- unplug, wait few seconds to let it turn off
- plug again and watch it going backward from 100% to the real percentage
- repeat until it will not fall back
Now it gets really charged up to 100%. How can i automate this?

I saw your link on the ebay feedback profile of the seller. I have the exact same problem and am pretty sure the batteries are just low quality and faulty. Its the second battery this happens. Exactly the same thing. The first time I got such a battery I fully discharged the phone up to a point it wouldn't even get to the boot logo, and the battery died. It wouldn't charge at all and that was the end of it. I don't believe there is any way to fix this but to buy another battery and pray.
