Battery Callibration on LG P880 - LG Optimus 4X HD

The battery in my P880 was lasting almost nothing! The percentage emptied fast! That's when I decided to calibrate the battery! Oh my god! Now is MUCH better.

around 12 hours with moderate use
also, battery is autocalibrated..
i guess its tegra related..
but i didnt find the need to calibrate it since ever..
and i restart my phone alot.. *by pulling its bat out*

Depends what you call moderate... when I'm using only as a phone, answering and making calls, lasts for more than two days, with wi-fi on (except when "sleeping".
Of course that if I'm using Navigon for 1 hour without charger its normal that the battery disapears
I use the display light at 50%, no power saving activate, and like I daid before, only using as phone at least 2 days (I don't receive calls or make them every 2 minutes of course)

How exactly does one calibrate the battery?

my moderate, i mean lil gaming and whatsapp all the time..
plus wifi always on.

One way is to drain the battery until its finished then recharge it.
another is to download apps like this to do a better job but you need to be rooted.

Just don't disconnect the charger when the battery reaches 100%. Keep it plugged in for another hour or so.
When pulling the plug as soon as the battery supposedly reaches 100%, my battery drops to 50% in no time, but when keeping the charger plugged in, I manage to get 3+ days with the exact same usage pattern (moderate usage on 3G with autosync on) out of the phone.

Finally activated my account. Can help you new guys out with this phone now. For charging my battery, I use an app called "Easy Battery Saver". Don't be mistaken, I only use it as a timer for when to unplug my phone.
Steps:
Drain your battery to somewhere like 15%.
Allow your device to cool off, perhaps for about 20-30 minutes?
Next, reboot your phone and see if the battery level is still below 15%, if its not, drain it again to below 15%.
Next, open "Easy Battery Saver" and just enable normal mode.
Plug in your phone to charge, and the "Fast Charge" bulb will turn yellow.
For me, I usually unplug my phone the moment the "Trickle Charge" bulb turns yellow.
I don't know for you guys, but trickle charhe scares me as I've seen some bad cases before.
Although the stock LG kernel might have prevented trickle charging, I'd still not risk it.
Finally, after you unplug your phone, ensure that you always drain it to 15% and below before performing a full charge. Please do not unplug or plug in your phone before 100% or below 15%.
In addition, it is not good to "heavily use your phone while charging.
Hope this helps. Just to let you guys know, I've been in this forum for ages, just that my account was bugged and I couldn't post anything. I have an adequate amount of knowledge for the phone, and if you can't understand some other tutorials, like somboon's from thailand, (don't blame him), feel free to send me a pm. I'll help you understand step by step.

It's been told here on xda a thousand times: Deleting the batterystats.bin will NOT calibrate your battery or something. That file is created new every time you charge your phone. It's just for statistics. Proper calibration can only be done on hardware level, like on the Nexus One/Desire with the Nexus One Battery Calibration App. But that's not applicable for our devices. If your phone dies out too soon (mine does, too) it's most probably some bogus app that keeps the system awake. However, i didn't find out yet which one is the problem. Can those who deleted the LG apps confirm a higher capacity afterwards?

Someone told me that enabling of "GPU rendering" in developer settings saves a lot of battery and saves the phone processor.
Is it true?

It does, to a certain extent. However, from my knowledge, the best way is to under clock your phone using the LG Gearbox app in the development section.

You won't because quad core is unnecessary. There's next to nothing that actually requires it so the cores just sit doing nothing

Why you still in V10F?
Have bluetooth OFF helps... GPS generaly is activated only when some app need it, soo, check the apps settings instead of turn OFF the GPS...
Wi-Fi you can set it to be ON only when you're using the phone, means that the screen turn OFF and the Wi-Fi too...
DATA is good to be OFF, even for you to spare some money.
Other apps can be draining your phone.
You need go know better the device and the apps, what resourses they use and how they work, then, decide what to do with them.

Steps:

I did try that and not working at all, my phone drain battery for nothing, even than i didnt use my phone it keep drain battery, so i drain my battery to absolute zero when phone turn off because battery is too low, and i pluged to charger for whole night and so far im on 3rd day(2 days 15hours 30mins) and still 30% remain, and i use my phone for some calls, text, internet,

mine drops 10% all day if i dont touch it ,easily lasts all day and night with normal use

Battery life?

Hi all lucky owners of lg optimus 2x,
I want to ask you a question about battery life of optimus 2x . Is it really better than single cored ones or same, i m not expecting better life really
Sent from my HTC Desire using XDA App
There's a good review in the optimus 2x forum:
http://www.optimus2x.net/index.php?topic=156.0
Conclusion:
30mn YouTube HD (wifi)LG Optimus 2X: 9% battery​Google Nexus S: 7% battery​30mn Neocore (3D graphics)LG Optimus 2X: 12% battery @ 74FPS​ Google Nexus S: 9% battery @ 54FPS​8hrs of stand-by LG Optimus 2X: 2% battery​ Google Nexus S: 3% battery​
Wow, quite good !!!!!!!!!!!!!!!!!!!!!
I think that test is a bit flawed... PaulOBrien reported that the Nexus S exaggerates it's battery % quite seriously...

You are used o2x. What can you said about battery life of subj? On sleep mode? On used mode?
Here is an interesting test of battery life of the lg o2x.

my battery life blows :/
Well, mine has a pretty good battery....you know now I have time, so I just keep playing with it all day, so with auto-brightness and WiFi always on, playing pretty much all-day I got through 1 day without my charger. Without wifi and less playing I think 2-3 days could be easily achieved.
I am using V10d rom unrooted.
It happended several times now. I need to change SIM cards often as I travelled to different areas during my work. Before I pull out the battery,it is at 50%. After I change SIM card and put back the battery, it drop to less than 17%. It takes me less than a minute to change the SIM card. What happened to the battery??

I managed to get 3 days+ out of it under average use. Could probably easily manage 4+ with setCPU or something underclocking the processor and turning off data, etc.

i'd like to know too. My battery life sucks. Barely make it through a day now. On MCR FR17..
This is one of many threads about this.. But i'll respond anyway.
I had same issue, after some tests, i found out its GSM part of phone thats draining the juice. With airplane mode on it was about 3% in 8h. I was on BlazingDragon, with some apps, normal phone use It lasted 24h on standby without any use, no more.
Yesterday, i tried to flash (lastest for central europe) stock firmware, including baseband, simply i got the phone into factory state. And well, during night with data off it was 1% (yes, you are reading it right, i woke up with phone on 99%), now 10h later with lighter usage (some mp3, not much, a little of tapatalk, gmail push on) i'm at 78%.
I dont have any software except tapatalk installed atm. Dont think my problem with with BlazingDragon rom thou, i suspect some application caused it, but dunno which one
I think it will last 2 days with current usage, and several days with data disabled (using it as plain old phone only for calls )
PS: I dont use any JuiceDefender etc..
Iam using slicks rom, if i only write sms and surf sometimes, i have to charge every third day, but if i playing THD games, i have to charge after 3-4 hours
+1
the stand by time is really nice but gaming sucks out everything from my battery
Other than the battery drain during standby, my current observation is that, say if my battery was at 50% before I pull out the battery (say if I need to change SIM card), after I changed SIM and put the battery within one minute, it suddenly drops to less than 17%. Why the battery loss 33% in no time?
People keep saying that the phone can last a week if it is on airplane mode, or by turning off data 3 days, but then why we need a smartphone of such build?
Has anyone compare the other dual core or tegra2 phones in the market how they perform battery life? Do they have such awful battery drain standby? LG said the battery drain was due to incompatibility of tegra2 and android 2.2. Why sell the phone in the first place? This problem starts from day 1. LG no QC or just want hiding this problem from customer?

it looks like a calibration problem. Either 50% or 17% reading was false.
Just did two full days after reflash with MCR.

Battery use

Can somebody help me out here? My battery life is really bad, today I lost about 10% battery indicator 4 hours with the phone lying in my pocket! When I use the phone its even worse. I am on cm7 nightly 09302011, and it seems like everyone brags about the battery life, just not me. 3g always on, bluetooth off, background data on, autosync off, no live wallpaper and å clock widget. What could be wrong?
Sent from my Optimus 2X using XDA App
Are you using a custom Kernel? Since installing the NeoBlaze kernel my phone has started using power on idle.. last night it used 40% charge while completely idle and not in use..
I don't really care because I carry 2 batteries around with me at all times, but it does seem changing around roms/kernels messes with battery life. Perhaps you just need to hit up eBay, batteries can be had for $2.80 shipped.
Without Juicedefender, 10% in 4 hours with no use is actually pretty good for this phone.. I'm jealous. I get that kind of battery life with data OFF most of the time.
No custom kernel. Thought I read in the forum that ppl got like 3% loss overnight. Maybe thats without data...
Sent from my Optimus 2X using XDA App
get widgetsoid and turn your data on and off (and 2g/3g) on and off quick and easy.
who on earth needs data running over night anyway ?
same as watching full hd videos on 480x800 screen..... thats just dumb

I guess 3g is the sinner. Installed JUiceDefender and went from 11h to 32h battery life.
Not sure what happened to my phone, I'm getting 4 hours off a charge now with relatively light use.. just some web browsing and screen off idle half the time.. Going to try topogigi rom and see what happens.

let your battery cycle a few times, this phone rivals my iphone 5's battery life, pretty amazing never had a phone before that did that.
No, if it dies that fast then it's user error.

There's no need to cycle with li-ion or li-po batteries. In fact it's explicitly bad for your battery to run it down to 0.

Running your battery from 100% to 0% is useful in recalibrating the battery in the event of cell mismatches, which can happen over time.

Here's a very good post for information about li-ion / lithium polymer batteries:
http://forum.xda-developers.com/showpost.php?p=40596097&postcount=3
You generally shouldn't need to recalibrate the battery on a new phone (since it's a new battery), but it doesn't hurt if you think your battery may be mis-calibrated. (for example, your phone sits at 0% battery for long amounts of time) Do you have any apps that monitor wakelocks on your phone?
i was complaining my battery was crap yesterday. iv gained 1 hour in battery since yesterday.
GSam reported 9hours 24mins avg battery yesterday. I cycled it once since then and today its showing 10 hours 38mins avg.
Hoping for further improvements.
The phone needs to know where empty and full battery is. I've always calibrated mine by fully charging and killing at least twice with every phone I've owned and had no il effects and got much better battery life afterwards.
So do I calibrate or cycle? If so, how do I do that? Im fully stock and the only battery app I have is the battery guru made for snapdragon devices. Idk if that's what's killing my battery.
Sent from my HTC One using Tapatalk 2
It does no harm to run the battery to 0% occasionally, but the advice i have seen is to try to not run li-ion / li-po batteries below 10% too often as that can shorten their life.
For a new device i would run it down to around 10% with normal use, then give it a real long charge till it indicates fully charged, then unplug it and wait a minute or so then plug it back in and leave it on charge another couple of hours to make sure it is fully 100% charged.
After you have done this whole procedure maybe 3 times, you should have a properley conditioned battery. My HTC One is usually at 50% or better after a 12 hour working day, so i am more than happy with the battery life.

You are totally wrong I am afraid. LiON and LiPO batteries do not have memories and neither like a complete discharge/recharge cycle. The rule is 'a little and often' as far as charging is concerned.

They do NOT have memory effect like nickel-based batteries, but they CAN suffer from cell mismatches which require re-calibration (aka fully charging, discharging, and recharging).

exactly!
Basically just use your phone for about a week, then you can start fixing it
My experience and questions
Thanks for this excellent post! I got my new HTC One day before yesterday and like the Vincent's post says, the phone had about 40-50% of charge when it came in the box. I was very excited to see the phone that I totally forgot about recalibration of the battery
I used the phone out of the box, and I have charged from 2 nights (from about 15% to 100% charge) and haven't run the battery the battery down to 0% yet (when I say 0% what I mean is the level of charge when the phone automatically turns itself off to protect from complete discharge). My questions below:
1) What should I do now to accurately calibrate my battery life? When I called HTC customer service today they asked me to do battery reset (steps below).
- Untick the quick boot under settings -> power
- Turn off the phone
- Hold down the volume up, volume down and the power button continuously for 1 minute (the phone seem to boot up and shut down 3-4 times during this process)
- Run your battery all the way down to 0% and then charge it fully to 100%
This seems to be a fair procedure but since it was told by customer service, I'm a bit skeptical. So I would very much love to hear some opinion of battery gurus here
2) Does the 2 night charging that I did affect my battery capacity (has the dent been made already)?
Please let me know, and thanks in advance!
PS. The battery life in my experience in the past 2 days has been decent (I have about 20% from 7am - 9pm) and I'm a moderate-heavy user!

New Motorola RAZR i battery drains quickly

Hi
I bought the Motorola Razr I yesterday, I been using it all day today.
But the battery is abnormally short. It drops very fast min 10% per hour to 27% per hour. I don't think this is normal for a new phone. The battery temperature is 38°c on normal use.
Am I using the phone wrong or did I get a faulty phone?.
I have nfc on all the time until 23% but after that I turned off nfc to see if that was the problem but it didn't seem to be.
I can get screen captures if needed.

you need some circles from full to down then you will se the real power.
but the battery with stock rom is not so great as with the custom rom from omar or max.

and at least you csn not easy change the battery by yourself

You might wanna figure out what is actually draining your battery. Search XDA for 'better battery stats' and install it. When your phone is not beeing used it should stay in deep sleep for most of the time, if not, check wakelocks to see whats keeping it from sleeping. For me it was mostly Google Now which caused the drain.
ok so the more i use the battery the better results i may get?
One of the reasons i bought this phone was because of the review on battery life e.g. http://www.techradar.com/reviews/phones/mobile-phones/motorola-razr-i-1098183/review/9
Now i have done a wipe of cache and data, did a factory reset. Charged from 10% to 100%. Getting the last few % is hard, this morning i woke up and it was still 99%. Went back after 1 hour to check it was 99% and dropped to 98% while the phone is off and charging.
Once its 100% again i will install the better battery stats as 696 suggested and post my results.
In my pretty long android experience this happens all the time with new phones, after updates.. You can do anything you want (cleaning cache, restart, etc), but it gets finally better by itself after a couple of days.
Don't ask me why, but it works like that.
Battery life of Razr i is excellent, best of all phones (incl iphones) I ever had!
Good luck and have some patience - so simple is that!
Recommended is to charge the new Phone full, before you turn it on the first time. A lil bit patience is needed, but that should help to avoid stuff like this.
And as the Guy above already posted, the battery will calibrate during daily use. It's the same, when you flash or update an Rom. You'll see the "real battery drain" first after a couple of Charges. And don't wipe battery stats in CWM, that's useless.

I've noticed it on a rather old device, a htc desire hd. (running a custom 4.4.2 rom) It lastest so long on 1%.
Probarly you need to re-calibrate your battery, after that it shouldn't get stuck on 1% anymore for such a long time

Once a month I recalibrate my battery, and it will sit on 1% for hours some times, and then only minutes the next it just depends. Just let it die then charge it to 100% uninterrupted. Normally they get uncalibrated after rom flashes and if you put it on a charger but don't let it charge to 100%.
I haven't put any ROMs on my phone. I'm still on stock Rogers rom.
How do I re-calibrate my battery?

Let it die completely then let it charge to 100% before you turn it back on, that's my process.
This keeps happening to me too. Battery drains quickly then stays at 1% for several hours. Lasted at 1% for 4 hours yesterday. I've done the "let drain until powers off and charge to 100" a couple times now but it still happens

I always heard that it's bad to let it die completely.

Hmm that's odd never had that issue, I rarely go below 50% during the day.

It is if you do it every time, but not if you do it once a month or after a rom install.

When your phone dies, the battery doesn't completely die. Phones shut down before the battery is completely depleted in order to save a little bit of the battery. So if you let the phone shut down from low power and then charge it back up there shouldn't be any ill effects.

Yeah, I know that, but I was just saying what I've always heard from people

This article is old but it explains why you shouldn't fully discharge a lithium-ion battery often! http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
batteries don't fully discharge even when the phones dies as an above poster pointed out. If you were to let it die then leave it that way for a few weeks is when you will start to have problems. the lower the battery percentage is before charging is correlated with how many cycles your battery has. So draining to 70% then charging is better than draining to 30% then charging. The point in draining to 0 isn't to prolong the battery but to recalibrate the software determining what the percentage of the battery is. This will not have any worse of an impact on your battery then letting it drain to 10% then charging. Batteries may actually still have up 20% left when you fully discharge them because manufacturers don't want your battery to ever actually reach 0.
If you never discharge down to "0%" then charge to 100% then your phone can never properly calibrate your battery drain. It is always a guessing game for the software so doing a full discharge cycle gives it an updated benchmark to guess off of. The effects to the battery are not that big of a deal. If you read up enough on them you will find that to be true.
when the battery gets hot, that has a much bigger effect on its life than draining it to 0. But clearly if you drain to 0 every day then that will have a huge impact on battery life because you may only get 300 cycles out of it where as you might get 3000 if you only drained to 70% every day. (rough estimates, there is real data out there regarding then if you want to know the real numbers).

I couldn't have paraphrased that article any better nice!
I've noticed this in my Moto X. 1% lasts for a long time lol. Not that it's a bad thing but a little inaccurate if you ask me.
Ever since I've bought my Moto X, I've always let it die a few times then have charged it to 100% (full cycle) but it's not made any difference. Sounds like it's a bug in the software to me.

did you charge it to 100% without turning it on? there may be battery stats (in a folder i can't remember but you can look it up) that you can delete to cause it to relearn battery level but i have read elsewhere that that theory is a myth and won't actually do anything.
IDK the logistics behind leaving your phone off, i just know i have done it both ways and it seems something else calibrates the battery when it is off that is not the android OS i guess but is the root level software for the phone or the bootloader or something. Im sure someone smarter than i could give a better explanation of the possible difference.
I've experienced the same thing on my Moto X.
Something tells me that it's somehow related to poor battery life... But that's just expeculation.

I always leave the phone off when charging fully. Have tried with it on too but same results.

search around for the place where the battery stats are located. I think the file just may be in the cache but I know i read somewhere at some point about the location where the software stores its battery stats so that it can guess what your battery percentage is. Search for that and clear that folder out and see if it helps. I would do this right before my phone was about to die at 1% then do the cycle if i were you. But that is just how i would go about things.

I've heard people say that the stats reset themselves at 100%. But that's just what I've heard. Haha

ya like i said earlier, i also did read that deleting that folder was pointless but who knows. If my phone was continuing to do what yours is then i would be trying all sorts of things that people said wouldn't work. Then i would throw the phone into beer, bc i can, bc this thing is pretty much waterproof as anything. SOmebody submerged the thing in water for 30 minutes and it was still running. So maybe throw your phone in beer as a last resort.
