[Q]Battery problem? - LG Optimus Black

Hello all,
I am now on Nova 8, after trying Cm7, then stock, then nova 8. The problem im facing is that I think the battery life is shorter than it should be. I used battery calibration app and when its close to 0% still shows 3000+mv, is this correct? Or it should be close to 0. After using this App the problem persist. Im not sure if its my imagination or the battery should last longer but with a light useage the phone hardly reaches a day.
Thank you in advance

Hy, when u'r phone is 100% use battery calibration then discharge u'r phone and whait to close (0%). Then leav it to charge 100% with out turning it on, is should work

First, this is the Development Section and not for asking questions. This should be posted in General Section. (Reported and now moved)
Whenever you flash a new ROM or exchanging one for another, you should always wipe battery stats (CWM). You can however do this now directly without that app. Charge it 100%, then reboot to recovey (CWM) then wipe battery stats.
To answer your question. You might have mistaken a battery drain would equal to 0mV. Batteries like ours has 4200+mV at full charge, and a discharged rate of about 3000+/-mV. This could be well explained by someone like huexxx.. XD CMIIW

[Q] battery percentage not accurate

Hi Guys!!
i've done what this link told
http://forum.xda-developers.com/showpost.php?p=10092321&postcount=11053
but everytime i reach 100% and unplug the charger, my battery percentage immediately shows 97%, be it charging with the phone off or on....
i already did wipe my battery stats in recovery a few times, the first time only it showed that the stats were wiped, after that every time i wipe the stats, it immediately goes back to the previous menu, without stating whether the wipe was carried out or not....
can someone help this noob out here.... thnx
FYI, i just installed darky's rom v8.0 with Voodoo's kernel 5.2(lagfix disabled)
when i was on stock, my 100% could last me about nearly half an hour
I have this problem too. (I am on Darky 9.02 and have seen it in Darky 8.0 too). BUT if your battery life is satisfactory then don't worry about it.
hows the performance on v9.02 bro?

9.02 is good but then so was 8.00. I personally think 8.00 was faster but its only been a few days and am still experimenting. I may remove the lag fix and still need to see if my battery is draining faster.
Also look at this post: Has some interesting but unverified info about the drop from 100% to 97/98% after unplugging
http://darky.ficeto.com/community/i...-how-to-calibrate-your-battery.321/#post-3839
Do you really want it on 100%? Easy, once it says charged, leave it on the charger for another hour and when you unplugged it should stay 100 for a while

Problem posted hundreds of times along with solutions like search the Rom makers forum and read the posts re this problem for starters .
Simple solution save time and effort is to ignore it .

thanx all for the advices.... tried the QueenAmy method, result is:
heavily used phone: battery 'died' at 2%(???)
charged phone until 100%(phone off)
switched phone on while still charging: 97% (didnt have to unplug charger)
waited...then it went from 97% straight to 100%.(funny)
then went into recovery to wipe bat stats.
rebooted and unplugged charger, battery still at 97%....
now trying to charge a bit more longer to see if can change anything... (fingers crossed)

left it on for about an hour, unplugged, straightaway the percentage drops to 98...
It's just a change in 2.2.1.
In 2.1/2.2, they 'stretched' out the battery life a bit to mark it up to 100%, in 2.2.1 they decided to just show it at the actual value. The reason your battery won't charge to 100% is to prolong the battery life, because if the charger always charged to 100% it would have a high chance of overcharging and damaging your battery over time.
There's no real change in battery life.
I reverted back to 2.2 and still have the problem. Maybe i shouldve flashed on 100% battery... Is it possible to solve if i do another fresh flash with 100% battery?

Just to clarify this, you actually cant over charge the battery on the SGS nor Li-Ion for that matter, what happens here is that the battery goes on trickle charge pre 2.2.1 and battery degrades faster if its kept at 100%, 40% is optimal for storage now with the recent changes the phone will pretend it has charged upto 100% but will stop anywhere from 99~97% yes there is no loss in battery life but dont consider 97% as the new 100%, theres already a 3% loss in this to begin with.

[Q] Battery Calibration - reboot?

I recently installed Serendipity and made sure the battery was at 100% while doing so (and deleted the battery file). I'm waiting for the battery to drain before I plug it in. Am i supposed to let it charge all the way again? Also, is it safe to reboot the phone while it is draining the first time? I want to install something using clockwork.
I'm being careful about this because cognition would report 14% battery life after 33 minutes of display usage and display eating up 96% of my battery....

There's a complete thread on this, I suggest you look it up.
After you reset your battery stats, it is suggested to do a few full battery circle (use til dead, full charge, rince and repeat). You should be fine after 2-3 circles.
Note tho that it will not improve your battery life. All it does is a attempt to tell your phone what % your battery life is exactly.
For your fast drain, I don't think it has anything to do with your battery calibration or your ROM. It's most likely a app (or a few) that are draining alot of juice or that are running w/o realy being needed. (Check your running services.. make sure you know which one to stop and not to***)
Also using a app/widget like advanced task killer can help your battery life as it will stop every app running with a simple touch. I suggest doing it anything you're not using your phone.
One last thing, display eating 96% of your battery is normal.. it's not telling you it's using 96% of your battery. It's telling you that during the time your phone as been unplugged, your display use was your main action.. probably cause you didn't make many calls or anything else.. Display is just about everything you do with your phone so it will always have some high numbers like that.

Yeah, I've seen the thread before but forgot about it. Thanks for reminding me. And my point about the display was that it was on for such a short amount of time, yet still killing my battery.
I am now down to 30% or so after 3 hours or more of display time after calibration & rom switch- and I was streaming music through WiFi and using Bluetooth headphones. So it it seems like it made a huge difference =D
Thanks

[Q]Battery indicator showing wrong?

The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance
Hello
Does your phone charge to fx 75% and after that doesnt get higher until after you restart the phone?

Yes excactly. But the numbers differs.
Today it charged to 100% though.
Got the same problem?
Sent from my Optimus 2X using XDA App
have you try calibrate your batt again
yes my friend have this problem too, maybe there is software bug
After flashing Celebration HD 2.0.1b I first used Battery Calibration from market to wipe battery stats. Afterwards the battery indicator problems started.
Yesterday i decided to wipe battery stats manually in CWM and drain to phone to 2% before charging, and afterwards I was able to fully charge the phone.
So maybe the bug in is Battery Calibration app?
I decided to install Juice Plotter to monitor the battery and compare it to one build in in MIUI. Just to get some more data.
Hello again
Yes i had the same problem as you, with my previosly 2 lg optimus 2x, and returned them because of the problem you mentioned. I am on the third op2x and luckily this work good
So if i were in your position i would try to go to the dealer and shift the phone with another lg optimus 2x.

The user said that he started to have problem after a new rom and wiping battery stats, changing phone for that is not the smartest move at all. Is like changing phone because your rom doesn't work.
I have a similar problem, after you wipe battery stats you don't have a reliable indicator, for me the phone took 3 hours to get from 99 to 100%.
I also noticed that my miui ( 1.8.5 same for 1.7.29) doesn't update battery stats when the screen is off so all those plotter don't work, and i think this messes up with the battery indicator (I guess the phone doesn't have enough data to make a decent estimate)
I think is miui + wipe battery stats that can be problematic
I know that but i am just saying that i also had the same problem with the stock rom.

How old is the battery? How many cycles does it have?
I know from laptop Li-Ion batteries that the voltage vs. capacity is not linear.
When discharging, the voltage will steadily drop to a "wear-level" where it will jump to an almost depleted level. When charging, this "wear-level" will be at the top.
Why I am telling this? Because if this mapping is kept in SW and you wiped it, Android needs to relearn it again. So at 1st complete charging/discharging you would see a % sudden drop/raise, but at the next cycles it would be linear with time (although the total time will be smaller than a new battery).
When laptop/phone battery tips talk about calibration, it is so whoever monitors the voltage (circuit in battery or SW) to know were the wear drop will be, so your estimates to be better.
As an example, I had a very old Thinkpad that did not have any calibration, and it would discharge to about 40% and drop to 5% within seconds. But when charging, it would raise steadily to 70% (from that 5%) but 70% to 95% in seconds. After years of use, that percentage gap would just increase (40-5 got 60-5, 70-5 on discharging).
PS: my current Thinkpad has 4 years and the battery capacity is 49% with 150 cycles. But this one has a nice feature where if the battery was above a certain percentage, plugging AC would not charge it (and thus save a few cycles). I used it set at 70%.
PS: LiIon batteries have cycle count, heat and time as main enemies. Also don't like prolonged (think storage) low charge.

[Q] just wanna ask x8 battery life

hello
i just wanna ask something about my battery life on my x8...here's how it goes first i fully charge my battery up to 100% until it says on status battery full...then i unplugged it..after it i texted for a few minutes...and i check the status of my battery and it says: 28 mins 23s on battery..my battery is on 96%..is this normal.? or somethings draining my battery,?
i use minicm7 2.2
this is normal since battery is heating itself while charging, and when it cools down it shows less percentage of itself... to maximaze your current battery life, calibrate the battery:
1. charge it to 100% no more no less
2. leave the charger PLUGGED IN, and reboot to CWM
3. there you should find somewhere under options or advanced "wipe battery stats", and you press that
4. reboot your device and when it starts up it will show about 91%, charge it to 100% and you have your battery calibrated
NOTE: the charger is always plugged in
ok thanks i'll try it... one question should i drain the battery before calibrating it.?..as in zero percent??

Yes , that is recommended.
Also , one advice from me.
Even after calibration , whenever your phone says 100% charged , reboot it while the charger is plugged. You will get the exact battery charge after reboot.
Do it every time your recharge your phone.
Then stop rebooting when you get a 99% or 100% after a fresh reboot. Trust me , it helps.
ok thanks for the advice i'll try that too...
it is normal dude ....mine is giving 1day on heavy use
use zepplinrox's supercharge script...it really made a CONSIDERABLE change to m battery usage time
I have one question: "Why my battery is giving 6-8h. My battery 2 days ago giving 24 and more hour." Sorry for my English, but i am from Poland
what happened 2 days ago? did you install new ROM?
The OP might not have needed to install a new ROM, just an APP or maybe just a combination of APPs running. My phone sometimes canes the battery in a couple of hours from 50% to nothing for no apparent reason. On both stock and custom (actually better battery life on custom) it lasts about a day but sometimes about 6 hours! Not sure what is going on as this happened on both the stock 1.6, 2.1 and the custom 2.3.4!

Extreme Battery Drain

Hello, it's me again with problems. I have an extremely battery drain, even Juice Deffender can't handle on this. When I put the phone on charger, when he turns off after 0 % battery status, indicator shows me 50 % min after only few seconds on charger, and it's fully charged for half an hour maybe. When I turn on 3g and connect to Net, from 100 % to 0% is ONLY 15 min ?!?! I have cm-7-20120812-NIGHTLY-cooper ROM, but when I had offical 2.3.6, it was the same problem. Can I check some-how what is the problem- software, calibration or battery? I did a few calibration without any success. I'm really sorry on my very bad English. I will be grateful if anybody can redirect me on the right topic. Thanks in advance
3G eats a huge battery. I would not expect anything nice from it. But seems that your problem is a bit more problematic. How long do you have your phone?
Make sure you are charging your phone until its actually full not just when it says 100% look here for more details:

Did you try wiping battery stats in CWM or recalibrating it?
I've tried wipe stats with Battery Calibration, and with CWM wipe battery stats. I've tried different ROMs, DroidACE, official 2.3.6, cooper nightly ROMs, and all of them have same problem. I've noticed that the battery is a little thicker in the middle, before it was flat, and now is a little convex in the middle. I've tried also discharging and charging for a 5+ hours, didn't help me. literally be emptied by 20 min of Use

Yeah man, Ive got the same problem.
If I charge it for about 3-4 Hours, I get a max of 5 Mins or so, with Wi-fi on.
When the Battery is about 10%, and I put it to charge, It immediately says 99% charged.
I've changed 2 roms, and still no effect, infact, its got worse.
Even Juice defender (even the ultimate version) dosent work, Not even Underclocking.
I saw the battery recalibrating thing and Ive wiped the battery stats, still no use.
I think there's a problem with the battery itself?
Im just sick of it.

If it's deformed, then your battery's life is over, that's it, get a new one.
You can try the freezing method to try and squeeze it for a bit of juice:
Charge to 100, Plastic wrap, in the freezer for maybe an hr (not too long), take it out, put it in your phone, charge it till it says fully charged, turn on your phone and check duration.
seems a deep sleep issue
Just abuy a new battery. I suggest a Anker branded one. Search a battery review topic at the Accesoires section. If you buy the Anker 1400mAh, your battery life will be even better than the original battery life. And Anker is trusted and cheap.

Since we're in 2012, I'm guessing it's a lithium ion battery.
Just plug it in and wait for some time (~15 minutes)after it reaching 100% to actually fully charge.
It would be best if you don't let it discharge below 20-30%.
Read more about lithium ion batteries by searching around the web for more info.

there was a problem in battery, I bought a new battery, not Samsung, but also has 1350 mAh capacity, and it's 2nd time on charging, life is about 2 days of using, average 2-3 h 3g, and playing games, half hour voice and maybe 30 sms and mails, and for me this is a very huge improvement from 15 minutes before death battery.

Hmm, I did get slight improvement once i calibrated using another app.
But Im still getting a new battery
anyone knows why phone's display blink-up randomly? I saw that earlier, and I thought that was because of battery, but obviously, wasn't that. It's totaly random. And, I have another question, I've played with *#*#4636#*#* code, and sometimes phone can't receive or sent messages, except when preffered network type is GSM only and only after turning on and again off airplane mode. I have cooper cm 7.2 newest nightly ROM.

I had the same issue when I was using Elegant white by TAZ.
But Then I flashed a fix for it.
I suggest you should too get in touch with the dev.
But first, flash the rom again.

Thank you. Anyone knows where is the official topic for cm 7.2 nightly cooper? I found one topic in development section, but at the end of it someone wrote that topic is closed on developer's request. And where I can find changelog? I saw that there is newest nightly update from 19.8. http://download.cyanogenmod.com/?device=cooper
