standby battery drain?

Sooo. I have had my Optimus 2X for 2 days now. I charged the phone fullt before goint to bed and left wifi on. (should turn off when phone sleeps)
The first night i lost about 3% of the battery. Great....
But... The second night i lost 42%!!!
I have been trying to investigate the issue and after some digging with spare parts i found out the wifi was on all the time the second night... Also for some reason car home allways runs in the background (starts at boot and restarts if killed) and spare parts claims car home uses the phone sensors 100% of the time.
Anyone else having battery draining issues?
Im going to charge 100% again tonight and run with no installed user apps. If the problem persists i try and freez some of the loads of sys apps that run in the background all the time.

I also noticed some battery drain on mine but not over 40%... its more like 20%. The battery really disappoints me anyway. I have to recharge two or three times a day?l maybe thr battery needs to get trained over time, I hope...
You found a solution yet?

My battery already holds up alot better now, then when i got the phone four days ago.
About 60-70% left after a 14 hour day with some surfing, benching and calling/texting. Much better then my Desire on stock ROM, but still nowhere near the Desire on custom ROM.
Looking forward to some community goodness
BTW, removing carhome.apk seems to make quite the difference.

That's good to hear. Is it common for batteries to act this way? Talk about wildin' out.

Same here

Quick question about best used on the battery ...
Should we dry the battery to 0 for the first cycle ?
Or only to 20% ?
Is it bad if we start to charge the phone whent the battery is at 60% ?

On the contrary:
modern Li-Ion batteries don't like it if you discharge them to a minimum. Moreover they don't have the memory effect that you seem concerned about.
In a nutshell: Charge your phone whenever you can, at any charge level. Your battery will thank you.
On the first few charges though, you should always charge to 100% to help the battery gain her full efficiency

hey thx about those informations
but then i'm concerned about people saying stuff like "have been doing 3 life circle" for me it does mean they put the battery dry clean ...

Went to bed with 64% charge on the battery. When I woke up (8 hours later), still 64%.

What's your usage like?

Hmm... My phone last for 6 hours before drained... Had it for a week now... Takes about 2 hours to fully charge up again..
I even hardreset, turned of wifi etc... but alas, 6 hours and it was out of power again...
And that was just by being in standby.
If I actually use the phone, I can see the percentages going down from 100 - 0 in no time..

Strange battery drops and screen flicker

I had been using Cassies Xtralite rom V8 along with Hydracore 4.3 Std for weeks and everything was fine. One day the phone restarted on its own and the battery dropped from 61% to 1% just after it restarted. Then the screen started flickering too and the phone shut down on its own. This was strange because I had just charged the phone to 100% 2 hours before that and it didn't make sense. Therefore, I charged it to full while switched off and tried again. The battery drained to around 80% quite fast and then after trying to enter recovery to clear the Dalvik cache the battery went down to 5% when the phone restarted. This repeated for a couple of days until I had to do a Full Wipe and flash the rom and kernel again. However, the battery drain and sudden battery drop after restart still remain.
I read about a fuel gauge and tried to reset it by taking the battery out for a couple of minutes after charging to 100% while switched off but that didn't help either.
Does anyone have any answers to this?
Thanks

Charge your phone to 100% and clear the battery stats in cwm
It doesnt improve battery life but improves the accuracy of the displayed battery percentage
Or try changing the rom and see if the problem still exists

some roms appear to be experimenting with battry percentage based on usage. Try another rom.
Ultimately I had to go back to gb, with partition and load bootloader and stay clear of the rom in question to fix my stuff. I dare not go back again because of this issue.
I think I had to do this cause the various roms messed with special partitions, which arent wiped or formatted properly throught cwm. Migrating between different roms didnt fix it for me. wtf.
all at own risk
edit went back and had issues again. Used above approach and it didn't work anymore. It sucks.

Thank you for your replies. I tried charging to 100% and recalibrating or clearing batt stats but it did't help much.
Actually yesterday my phone would not boot and stuck to the bootloader. I had to do a factory reset in CWM to load again but as soon as it did the phone worked for 1-2 hrs and then reached around 70% batt fast and the screen flickered and turned off on its own. Uppn restarting batt was at 5%
Tried restoring a nandroid from mid September and things are slightly better. As soon as it starts the flickering I plug it on the AC and it doesn't die, but that's not always possible. It might have something to do with the batt voltages. I had flashed a Hydracore OC version and it might have messed things up. When charging the voltage goes over 4200mV.

Hi,the very simple methode for your problem is........buy a new battery and insert it in your phone then start it and problem solved !
Very easy don't you think ?
Btw,repeatitly flash rom,kernel,or all side stuff with flashtool or like that and use your phone with high frequency kill your battery very fast !
So,
the first symptom of a dead battery is autoreboot and quick down level.
Don't try to use battery test in factory with custom rom because 80% they not support it
In this case,you have always wrong indications in test mode (batteryHealt=good/100)even if your battery is dead !
Trust me and good luck
Oh and,stay away from chinese battery with high voltage and good price !
Prefer Choose stock or mugen power
Ciao

Thanks for the replies
In fact the battery appears to be the problem indeed. I took it out and placed it on a flat table and it would spin with ease. It is bulged quite a bit. Now looking to buy the original 2500 mAh battery by Samsung and the 2700 mAh battery by Anker to have a spare

If your battery is bulged then it's a dud and won't retain charge, plus you run the risk of it bursting which will kill the phone outright.

[Q] Battery almost empty after rebooting?

So, I bought a Galaxy S too. Nice phone. Awesome display. Delightful user experience. Now, few days later, after rebooting my phone, battery level drops from like 90% to just 10%, and restores to the original level after some time. What should I do?

Not enough information. Are you rooted? Are you on a custom ROM or kernel? Have you tried running the battery completely dead until the phone shuts off, then charge it all the way to 100%?
Tappin the talk

If ur on a coustom rom..this issue will be there in beta versions of the rom!
Also which rom u using?

Sorry. Yes, it's rooted. Stock XXJVU, Semaphore kernel 2.5.0b (been using CF-Root and stock kernels before that, but there were no differences in battery level readings after reboot). Nope. How many 0-100% cycles would be necessary for it to do the trick (or fail)?

what i presume is that your battery hasnt been recalibearated.. it might be a kernel issue too..

Might be a faulty battery. Check if it's swollen or anything, and try replacing it if you can get a spare.

Yeah, you need a new battery. Get the 1800mah Anker.

Dev, I am facing problem after buying a used Galaxy i9000 .
1.I charged my battery fully [100%] , then using after 5/6hr when battery goes down to 34%-35% , the Cell phone suddenly got shut down , When I plug it in , then it says battery was empty . Then I have to charge it again .
2.When battery is 66%-67% , I tun off my phone and started after 5min , I saw it's only 17% !!!
What is the remedy/ solution for this problem .
[Don't say to change ROM/kernel/ clean delvik cache , I have already done them]
Do this problem will be solved by Changing battery ?

Yes, as Knuckle said you will need a new battery perhaps the 1800 MAh.
Hope i helped

Is there any battery on eBay you guys would recommend (free shipping, battery price up to $10 if possible)?

I thought that someone bought such stuff on eBay and could suggest me some reliable seller(s) so that I don't buy some fake garbage labeled as Anker that will blow up in my pocket. Nevermind.

Okay, in order to not experience bad battery life again, what exactly should I do once my battery arrives? Wipe battery stats, few 0-100% cycles, later just make sure battery never goes below, say, 25%, and I should be fine? Please correct me if I'm wrong.

Yeah, pretty much what you just said. Wiping the battery stats is a bit pointless but do it if it makes you feel good
Polarcell or Anker are the ones to get. There aren't any fakes of those that I've heard of. All the fakes I've seen claim silly capacities.

Is your Galaxy overclocked?

I mean, consider lowering your CPU clock as it seemingly stopped sudden blackouts on my Galaxy.
EDIT: Nope, it didn't.

I had same problem. Bulged battery. I bought a new battery and it fixed the problem
You need a new one!

[Q] Best Way To Calibrate Battery

There is no BEST way to calibrate your battery. We all have our own theories.
The stamina mode thing is a semi bug, you shouldn't worry about it.
With semi bug I mean: The phone learns from your daily tasks and then adjusts the stamina mode time to it.
Mine also says 9 hours, with stamina mode 21 hours or so. But I'm not worried because I can get a lot more then that.
When you clear the cache (Dont remember from what service/app) the stamina mode time resets to "normal".

Best way to calibrate your battery, is keep charging your phone when it needs to be charged, and make sure that you followed the charge instructions when you opened the box. Then after about 3 weeks the battery will be as good as it is going to get.

There's an extensive discussion regarding the necessity of calibration in the thread linked in my signature. If you read the first few pages you will realise it is not needed.
Sent from my C6603

Calibration is not require...if your phone die too quick get one of those portable battery charger, it look like a damn tampon, but it will do the job, 2000mah.

Actually
I recieved the phone as a gift and I think it was turned on and tested and they didn't charged it before first use...
Is this first charge thing that effective?

No not really. It's a li-ion battery and they just don't need that type of treatment. Alot of people will harp and whine that it does but that's pretty much just people stuck in old ways (sony themselves have a note with it saying charge for 30 minutes before use) . The only thing that's "bad" for the battery is continually jump charging it eg plugging it in to charge at say 40%, only letting it reach 60%, unplug it, use it for a few hours and do the same thing. That and maintaining a full charge for a long period of time or maintaining a very low charge for a long period of time.
However I would charge my S2 every once during the day, then again at night and leave it on charge till the morning. Leaving plugged in for excess of 5 hours every night at full charge hasn't caused any noticeable harm. They have sensors to slow current flow to a trickle when they are at full charge to prevent over charging so I guess that does the trick to prevent it from reaching true 100% charge.
Rule of thumb; when the phone tells you to plug into charger, that;s right about the best time to do so. Later wont matter so much, but earlier and you are basically wasting a charge cycle and shortening it's life.
My S2 is still on it's original battery though and it is still going strong after approx 2 years.
The best way to calibrate would be to stop fiddling and let the phone do it's thing. Reboots and recovery mess with it alot as alot of battery percentage gets lost during both of those and throws it way out. A couple complete charge and discharge cycles without powering down should be all it needs

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.
i dont think your battery is faulty give it some tryes!
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.

Did you manage to get to the bottom of the question?
I bought my Razr i 3 weeks ago, I had high expectations about the battery, but the battery only lasts about one day and half, is this normal? I am not a heavy user.
