DamageControl battery recalibration?

I read this: http://forum.xda-developers.com/showpost.php?p=6399061&postcount=3546
It says that you should get 100%, then turn it off and wait until it is green. After this, wipe the battery stats or use the adb command. Then, let the battery die after normal use, and after recharge..
My question is, can anyone recommend some battery killing apps that will do the job?
Thanks in advance!

i think you answered your own question

That public embarrassment was not necessary. *sarcasm*
Yeah, but isn't using an application considered normal?

sorry, anyway, I used pandora overnight that worked pretty well. with pandora you can lock the screen on also that helps out.

I could be wrong but I thought that the way Lithium batteries worked makes this kind of calibration useless??

This dueling argument will go on for centuries. I wish a battery manufacturer would step up and release some white pages to say one way or another.

I don't think it is so much calibrating the battery, but calibrating the phone to the high and low points of the battery. Older battery types required conditioning, not calibrating.

Bingo! Having three batteries (2 after-market TouchPro 2 and the OEM), I even have a performance difference between the two types. I've since set the OEM battery on a shelf and only use the TP2 batteries, as they are identical. I haven't had a battery issue since calibrating using one of them.

Battery Lifetime

Good Morning folks,
as some of you are already proud owners of a LG2x, I would like to know how the battery lifetime really is. Are you guys satisfied? How intensive are you using your device?
It would be nice, if you can describe what you are running, like wifi, gps and so on... pretty sure you know what to write to give me and the others a clear view on the battery lifetime ;-)
cheers,
Manuel

Yesterday I got the phone.
On very very very hard use it took me about 7 hours for the phone to be 0%. That is kinda good in my eyes.
Today I'm doing normal use, to see how the battery goes.
I withnised 100% tot around 60% went kinda fast, but from 60% till 0% took a while
So stay tuned for the today test.

I got the phone the day before yesterday started charging it. Then in the afternoon it was fully charged and i started to play around with it. It did good but then today i had it fully charged overnight and now - at around 15:00 it dropped below 15%! I hadn't been using it for other than a few calls, a few texts and less than 10 minutes fooling around.
Something is up - i don't know what, but the battery info shows most battery usage was drained due to cell standby and mobile standby...
I don't know what really caused this Other than that i love this phone, i just hope i find the reason for this insane drain soon - i tried rebooting and even installed advanced task killer

Hello, I cant really help much on the battery issue other than to say give it a few more cycles before getting too upset.
The last new battery I had in my iPhone took a week to really settle down.
I would uninstall advanced task killer as I believe it has issues with froyo and is not really needed.

Ok thanks - i think i will then

had the phone 2 days now, and feel like the battery drains fairly fast, had a BB before this and im not used to having to charge everyday. Will se how it goes the next couple of days.

Ok, it seems a lot of people already got their device. Is there someone who could try to unload (by heavy use or something else) and reload the battery again and again to get a feeling of the behavior after some loads?
Thanks!
Update: I have an update from a German guy for you who claims to found out that the service "nvrm_daemon" is the one which consumes the most power. Anyone an idea what it is? The "nv" in the name sounds like nvidia...

I should be clear - I do not mean +48 hours battery, I mean I have used the phone for only 48 hours... This includes charging.
But still, much better than my Nexus One. At the same time with the same apps and usage I have 40% and on my Nexus I would have 15%.
We all still need some days (~1 week) for the battery to settle.

okay in Eindhoven its in stock at a mobilephone shop. i seriously thought about to drive to the shop ... its about 260km from Paderborn
but lg said three days ago the 2x will be available end of next week. so now its up to amazon and its time to say goodbye to htc ... im really curious about the lg 2x
@xmoo thanks for your impressions of battery life. i was a little afraid of power consumption because of the dual core but that sounds fair

hi, 72 hours with the Optimus 2x and i have the same problem with the battery, it drains so fast!! with few use from 7am till 17pm 100%-32% !!! but i think today is better..
here in Antwerp,Belgium there is in stock at pdashop and gsmwijzer

Ok i'm doing a real-life test atm after a few charging cycles.
What did I do/ have I on?
Have I on: Everything (gps, data, wifi (if possible),...)
What did I do: Some gaming, few youtube movies, few short calls, watching mails, some internet browsing, send a few texts.
I'm using the app : Juicedefender in combination with ultimatejuice (this prolonged my battery 2.14x!!!
How long? : Atm i'm using my cell (from full charge) for 44 hours and I still have 39% left! This means that i could get it to run for 3 days on 1 charge!
Note: this is after doing a few cycles, out-of-the-box use gets you the day around!

[MOD][KERNEL] Battery Life eXtender (BLX)

Older types of rechargable batteries exhibited a 'memory effect' which made it neccessary to completely charge/discharge the battery when using to prevent degradation of the capacity. Modern Lithium-Ion batteries like in the Nexus S do not show this problem and thus it is not necessary to use the battery in complete (dis)charge cycles. In fact on the contrary, it is commonly accepted that both very low and very high charge states accelerate the degradation of the battery capacity (that is why you should store Li-Ion batteries at around 40% charge).
While a low charge state can be simply avoided by charging the device more often, the battery in the Nexus S by default is charged to around 95% capacity and I could not find any app or tweak to stop the charging at a lower capacity. Thus the only way was to use the manual override and pull the cable which is annoying since one had to monitor the charge state.
So I implemented a simple tweak I called Battery Life eXtender (BLX) which can be used to set a limit for the capacity to which the battery will be charged by passing a value between 0 and 101 to 'charging_limit' in '/sys/class/misc/batterylifeextender' (101 by default).
Changes to the source code: http://www.pastie.org/2516542
BUGFIX:
The battery status is set to 'full' once the user defined charging limit is reached.
Bug fix: http://www.pastie.org/2534319
BUGFIX #2:
The charging limit is set to 96 by default which will mimic the behaviour of the stock kernel. Also, the maximum value accepted by 'charging_limit' is set to 96.
Bug fix: http://www.pastie.org/2560599
BUGFIX #3:
1. Made BLX compatible with the 100% charging 'fix'.
2. If the charging limit is set to the maximum charging limit, charging will not be stopped until the interrupt signal is received from the MAX8998 chip.
Bugfix: http://www.pastie.org/2751140
No further patches will be published here. I have set up a git repo for all my tweaks. Each mod has its own branch to keep the tweaks cleanly separated and one can simply pull the latest patches from the corresponding branch.

Yeah, the drawback of course is the shorter battery runtime. If even a fully charged battery still is not enough for you to get over the day, this tweak is not for you. However, I mostly use the Nexus for internet, email and music and for me a fully charged battery last for about 3 days. So in my case when setting the charging limit to let's say 80% that is still plenty of reserves.
Before I wrote this tweak I thought about if it actually makes sense to try and prolong the lifetime of these batteries because they can be easily replaced and are also pretty cheap. However it seemed like a good idea purely from an environmental point of view (even if there is no climate change like Rick PArry totally has convinced me).

i thought about the need to prolong the batterys life too. i thought about how long id be using my phone as a primary device before i get a new one vs the actual life of the battery. i figured id replace the phone before the battery actually died. of course, there is that odd random chance that the battery will die much quicker than expected. my original g1 battery from 2008 is still good, and i abused that phone for a long time. but, there is something else that i didnt think about. there are lots of people in the world that are less fortunate than i am. and they need their devices to last them as long as the devices can because they cant afford getting new ones. and that includes the battery too. they would appreciate something like this. of course, there is that envirenmental thing that you touched upon. less crap destroying our wonderful planet

[MYTH] Wiping battery stats helps

There you have it, in the title. Google engineer Dianne Hackborn, who has previously explained Android’s hardware acceleration, took to Google+ again to clarify some myths about the Android operating system. This time, it’s a point of common advice that you’ll see in virtually every FAQ thread about custom ROMs and flashing: wiping battery stats in order to improve battery life.
The reasoning behind that piece of advice was something like this: If you, at some point, did not charge your Android device fully (for example, only to 80%), it would supposedly remember that battery level as “fully charged” – in this case, you’d only ever get to use 80% of your battery, which is of course less than optimal. So, if you wipe the battery stats, usually done in ClockWord Mod Recovery, the device would “forget” the previous level, here 80%, and instead charge to the full 100% once again, thereby re-calibrating the battery. Or, as Hackborn puts it in more technical terms:
"The battery indicator in the status/notification bar is a reflection of the batterystats.bin file in the data/system/ directory."
However, as she explains, that’s not the case. Because those battery stats, stored in the batterystats.bin file, are only used to maintain information about what is using the battery when not recharging. That is, it essentially holds the information displayed in the Settings > Battery screen. Nothing more, nothing less. Thus:
It has no impact on the current battery level shown to you.
It has no impact on your battery life.
What’s more, you’ve probably noticed that the battery usage data is reset once you recharge your device anyway. From this you can correctly deduce that the battery stats are wiped as well – every time your device is recharged. More or less every day. If there was any effect, you would’ve noticed it without going into recovery and doing that stuff. Typical placebo, eh?

I saw that behavior on my previous Revo. Sounds like a good question to ask her.
I stopped "calibrating" the battery since that previous phone and have had no problems. Reading mtm say that he never calibrates with all he does with his phone, I am on that boat. Reading the quotes above is reassuring.

It's a volts/amps thing. The lower your battery is, the faster it will drain. Rebooting your phone takes a lot more energy for all the necessary operations during a boot up. Without going into detail, the amperage will pull voltage down faster on a curve as the battery level gets lower, just as it does when charging.
When charging, batteries will not only appear to charge faster for the first 40-50%, but they are because the charge voltage is much higher than the battery voltage, giving more force of energy movement. As the battery voltage increases, that force is less, therefore taking longer to push amps into the battery.
The reverse is in effect on draining. I would safely say that you likely wouldn't see that much of a percentage of change for a reboot when your battery was fully, or near full charged.
Hope that helps... I also see a major percentage drop when rebooting my phone with a battery at less than 40% charge left in it. If the battery is mostly charged, I don't notice much more than a percent or two drop.
If this isn't helpful enough and need a better explanation, just let me know and I will try to explain it better. It's just basic electricity 101.

@ cybie
Thanks for that bit of info, your explanation was very clear
Sent from my VS910 4G using Tapatalk

the battery drop seems to happen quite often when you flash a ROM mostly I have a question might sound dumb but since the phone is on and all systems are being active wouldnt that use more of your battery life

Damn you Hicks... next you are going to tell me unicorns aren't real.
Yesterday I was at 25% I reboot, and it warned me that I was at 15% upon starting up. I don't think it has anything to do with anything. The phone ran as though the life was still at 25% (an hour or so with heavy-ish usage.) If I have done a lot of rom-ing and theme-ing I will recalibrate (just as a reassurance to myself) I am sure it makes no difference, but it puts me at ease, and really being self centered... isn't that what life is all about?
Poor communication between the battery stat program, and the display program, could this be the thing that is driving everyone nuts? Maybe the two programs need a class to express their feelings better.

Lol sorry! I'm really not trying to be all "doom and gloom." Just thought it was an interesting find lol.

An Observation
Back in the day I had an Incredible. It was truly an incredible phone. With the exception of the battery of course. There were/are always two camps or schools of thoughts about the battery. One was that you have to "condition" your battery to get better life, the other was "F it, the battery is fine". There was also the "bump charge" mythos going around as well. I think, and this is just my opinion, this is the same thing as the wiping of battery stats every time you flash a ROM.
My experience, both on the Incredible, the Inc II, the Charge, Revo and Bionic, (some of these are my wife's phones) is that conditioning the battery, or wiping battery stats are just really, as Spc pointed out, a myth. Our batteries die faster when we flash a new ROM cuz we are playing with it more. We have a new toy again.. same with themes...or new kernels.
Every time I wipe my battery stats I end up with much worse battery life for several days.
But thank you Hicks for posting the article. Its always good to read a debunked myth!! Bravo!!
These opinions are mine and not intended to troll, or irritate or annoy people. If I do, sorry.

Not sure if anyone else has seen this....but i've found charging a little while longer after it says 100% seems to provide battery life.
If it take it off the charger right away...i get about 8-10hours. If i keep it on a few hours longer, i seem to get about 12.
I'm running at 1.2GHz...gVolt

Performance and Battery in JB.

I was wondering. I looked everywhere and cannot find exact confirmation or Review. The 4.1.2 update is coming soon for the Optimus 4X and I read on 2-3 blogs that it'll apparently improve battery life. Is that true? Has anyone tried that themselves? From what I observe on my 4X that there are a couple of apps running in the system sucking up the battery. Will the future update fix this to extend its life? Sorry if this question was asked before and/or I've made a double post.

One day+?! Holy-- yeah that's surely an improvement to what I'm experiencing now. Is the phone running smoother as these blogs say? Any crashes/freezes or its a perfect charm. I'd just want to know what to expect...
Also, I've noticed that my phone tends to warm up from... almost everything. Is it still happening?

Depends on what you think is important. My phone is my "phone". I expect it to be as such. I can't imagine Web browsing for 3+ hours on my device. My Dell mini is better suited for that task and has better then 3+ hrs battery life. But maybe if your a gamer or a Facebook addict or Web browser cowboy, you find like people that use their device in the same manner as yourself and then compare notes.
Because of my job I'm often on the go and don't have the opportunity to recharge my device at leisure. It's nice to know it can be used as a phone all day and I'll still be able to call my wife at the end of that day. There if definitely improved battery in 20x after a few services are disabled and be r uninstalled. Prior to leaked JB my device required recharge after i got home. This is how I use my device and the condition under what I use it. These are my results but your milage may vary.
Yes the interface experience for me feels silky smooth. No lag, and no crashes or FCs. Best device I've owned to date.

its not specificly the browsing he did that makes the post usefull unlike some people posting battery charts its the fact that he posts screen on time rather then the chart.
the full charts are useless as you cannot see how often the phone was actualy used.
if i link you 2 charts 1 with slow battery drain in standby and no apps used at all (no screen on time) lasting 2 days exactly and 1 with near no battery in standby and 4 hours app use.
they both look the same if you post a battery chart but only the second one shows the potential of the battery life.
the first just shows the phone needed to be charged after 2 days the second showed the phone is capable of lasting 2 days with near no idle battery drain and gives a verry descent 4 hours screen on time.
a phone that is configured correctly and had good 3g/wifi signal and has 3g/wifi managed correctly, has no apps with adds and no apps that drain battery wil berely use any juice in standby leaving almost all the juice for screen on time.
a badlymanaged phone might drain up to 10% an hour because of adds and poort wifi/3g management/signal.
so in a perfect world (which we should aim for) only screen on/inapp time is important as there should be no other power hoggers.
