[Q] Charging optimus one - Optimus One, P500, V General

Hi guys i just bought optimus one yesterday and then i charged it for the first time 4 hours until battery empty. My question is how long should i charge it after i charged it for 4 hours. i am correct the sale lady said 4 hours
what should i do next to extend my battery life plss give me some tips in charging thanks

LG recommends you do a full charge / full discharge cycle when you start using the phone. So if you fully charged the battery (and I think 4 hours was enough to accomplish that) now all you have to do is wait for the battery to empty and then fully charge it again. You don't have to keep it plugged in for 4 hours if the battery charges faster. When it's full, you can unplug it.
Then, the best practice for this battery is to charge it whenever possible, even if you still have enough to go throughout the day. Keeping the battery over 30-40% at all times gives you longer battery life, but once in a month you should perform again a full discharge / full charge cycle to re-caliber the battery power meter.
Please read this for a better understanding of how Li-Ion batteries work and should be taken care of.

thanks master but last night i decided to charged it at 1% then i slept and my phone was charging for almost 6 hours. it this ok? i only do full/discharge one time?
BTW it this normal that in status it said not charging instead of discharging?

Yes, it is OK, and yes - only one time. To be sure, read the phone's manual. It says there how to proceed - please ignore the sales lady. Then you may do it only once in a while, to keep the power meter accurate.
Regarding the full charging/discharging cycle: Li-Ion batteries don't need that. There's no "memory effect" plaguing them, as was the case of NiMH or NiCd batteries who lost capacity if charged less than 100% or before complete depletion. Or, simply put: charge this battery as often as you want, for as much or as less as you want.
Furthermore: Li-Ion batteries have a limited charge/discharge cycles count. Around 500, I think. If you charge the battery more often, before dropping below 30%, the charge doesn't count as a full charge. This gives you a longer lifespan for the battery before replacing it (but not a longer time before the next charge).

Yes, that is also normal. Mine says "Not charging" in status too.

thank you so much master it enlightened me btw can i ask you about missed message flasher? or at least do you have backlight notification for p500 that working with go sms and normal messaging

Tomatox works well

First time charging
Hey,
I've just got my LG Optimus One delivered, I'm charging it and at the start I could see it was charging but after about 2 and a half hours it's been now, I can't. So do I just wait until it's fully charged and the icon will come up itself or do I press the unlock/power button to see how much it's charged or any signal it's charging?
Just asking because I don't want to turn it on when I'm not supposed to and mess the intial first time charge up.
Thanks.

is there any apps that actually drains batt then do a full charge?
I use battery doctor but sometimes it is hard to do a full charge because to do a full charge battery has to be less than 20%
but at the end of the day (before going to bed)
my battery still at 30% ...

lol nothing happens if u dnt hav full discharge. Its jst a recommendation for good battery life, jst buy a new battery if ur not satisfied with ur battery life rather than breaking ur head before putting it for charging...

charging rate
After some search I was unable to find an answer to the question:
What is the charging rate (in mAh) of LG P500 default adapter?
If I buy a replacement of original micro USB charger, what can I use?
500 mAh, 1000 mAh, some other?
Is there a difference for the battery?

Input= 0.2A
Output=0.7A

[Q] Quick Question About Battery Calibration

Hey everyone,
I'm using the "Battery Calibration" app to calibrate my GS2 battery, and I have already charged it to 100% and wiped the "batterystats.bin" file, and completely discharged it.
Now I have a question about charging it back to 100% - I'm going to be charging it while the phone is turned off, so how long should I leave it on charge before I can be absolutely sure it's at 100%? Some posts suggest 24 hours, while others say overnight or even 8 hours or so is completely fine and enough for the battery to become fully charged. Also, I don't need to "bump charge" to properly calibrate it, correct? I just let it charge to 100% now, and then I can use it as normal, right?
Thanks in advance for your help!
8hours ish should take you upto 100%
And after its upto 100% its fine to use it as normal.

...yep...when you see on the display (by clicking home button) the battery icon showing inside 100% then you can unplug your phone and use it normally...battery have a limit of charge just to avoid corruption so when they are at 100% they automatically stop to receive more charge...that's why I think is useful to leave the phone in charge more than he need.

Thanks for the responses guys!
Now, it has been about 3 hours since I put my phone for charging, turned off, at a completely discharged 0% battery (I even tried download mode before I put it for charging, to make sure it was completely discharged), and now the charge meter is showing 100%...
I'm pretty sure that 3 hours is a VERY short time to charge to 100%... I haven't taken it off the charger yet, so would you recommend waiting a few more hours (maybe 5 more hours?), or is it fine to just take it off the charger right now?
I'm worried a bit now, because 3 hours seems an extremely short amount of time to charge a battery that is 'supposed' to run for 18+ hours...
Well, I just read that 3 hours is about normal, so thank you for your help!

...you are welcome bro
Firstly, there isn't such a thing as battery calibration with Lithium batteries. Since there is NO MEMORY EFFECT.
Lithium batteries are not Lead Acid batteries, it does not need 8hr to 16hr trickle charge.
Charging is controlled by BMS, there is no such thing as Charging past 100%. So when it is considered 100% by the BMS (Voltage), the BMS will stop charging it.
Lithium batteries gets damaged when there is less than 10% charge, so emptying it to 0% is not a good idea. You cannot really extend Lithium batteries lifespan since it only has a 2+1/2 yr lifespan, 2000 to 5000 deep charge cycles and around 2,000,000 micro charge cycles. It is better to charge anytime you want, as long as it does not go below 10% (Most electronic equipments will state 0% at that time).
Deep Charge Cycle, when close to 0% (10% charge left in battery) you can charge 2000 times back to 100% (depending on quality of battery)
Micro Charge Cycle, when roughly above 40%, you can charge 2,000,000 times back to 100%.
Soooo..... would you like to limit battery charging cycles to 2000 or prefer that you can charge it 2,000,000 times?

battery won't charge past 96%

Hi guys, I am at my wits end with this stupid phone, If its not one problem its another. I was convinced this phone would have amazing battery life once seeing my cousins AT&T version, I bought the UK T-mobile version and its been plagued with faults. The main fault it has developed now is that it won't charge past 96%, I have configured the battery and installed the 1% battery fix and nothing is happening also my battery has been draining quicker than usual. Sometimes I get 13hrs sometimes I get 7hrs!? Could someone give me some advise? I was thinking of ringing my insurance company for a replacement (as it is with my bank and usually they just replace the phone)

I'm sorry, are you sitting in front of my phone? I have followed this correctly on another atrix and it has worked for them, I don't know why its not working on mine I have followed it through properly.
How long have you had the phone?
One thing we all have to consider is that since the dev community has had to provide "fixes" for the Battery Reading on the Atrix it might be safe to say that at some point the measurement might become too accurate. What I mean by this is, I've had my phone for almost a year now and I'm pretty convinced that the reason my battery won't charge past 97% is because of the natural degradation of the lithium battery. It is a fact that lithium batteries can lose up to 10% of its charge capacity after a year. So I've accepted the fact that my battery just might be losing capacity and the battery mods I have applied to my phone are just that much more accurate.
This reminds me of the recently released Galaxy Nexus and people complaining about the signal and Verizon responded with that the "reading" was too accurate and that they'll release a patch that will basically "lie" to the end user about the strength of their connection.
http://www.androidcentral.com/verizon-galaxy-nexus-signal-strength-its-not-us-its-you
Verizon is just basically saying "Here, let us cripple your phone for you"

I have had the phone for about 3 months now. This is why I am saying its weird. The fact that it dies so quickly is another thing I got about 7 hours of moderate use with about 1hr 45 display time with 10 mins of music and about 10 texts and a few phone calls(about 3 short 5 min ones)l
All of you are talking percent. What is the power level of the battery at max charge? Battery showing charging to 100%, or any other percent, and having full charge are not the same thing.

Could be a faulty battery. If you've only had it 3 months I would try to get the battery replaced if it has drain issues.

The battery never reaches 100 on the phone it will sit there at 96% and even the battery calibration app says the battery isnt at 4200mv (which apparently it should be) its at 4190. I never charge mid way I always let the phone get to about 15% then chuck it on charge.

Well I use the internal android one but I want to know whats draining it because today nothing was running, i had everything shut down and frozen that wasn't necessary.
You might need to use a 3rd party app to find the "rogue" app/process. Other than BMW, I also use System Panel to monitor it if I notice my usage time is depleting, it works well. You have to have monitoring activated and it's only available on the paid version, but you can use the free version to manually watch your apps/processes.

Ok so I recalibrated the battery and got rid of the 96% freeze but now the drain is quicker than ever :S
have you tried wiping battery stats as well? Also, when you recalibrate, do you go through a couple "full" charge cycles? As in, do you allow the phone to fully discharge and then completely charge it plus at least an extra hour? I know that lithium batteries do not have the "memory effect" but I think it has more to do with software rather than the battery itself.

yeah i do wipe battery stats but the mAh is not going to 4200 its stuck at 4186 nd wont go past 98%
Something else you could try that I've read around here.
1. Charge the battery for like 4 hours until it won't charge anymore.
2. Unplug the phone from the charger, turn it off, and then pull the battery out
3. Plug the phone back into the charger (Do not put the battery back in yet)
4. Wait for the phone to show an image of a battery with a question mark in it.
5. Put the battery back in.
6. Wait for it to recognize the battery, it will probably give a very low percentage like 5% or 10%.
7. Do not turn it on yet, let it charge for another hour or so.
8. Once you return, it will still probably show a low battery reading, ignore that and boot into recovery while it's still plugged in by long-pressing the power button and when you see the green led notification light press and hold volume down
9. Wipe battery stats and then reboot.
10. Wait for it to boot and then unplug it from the charger and check the battery reading.
I really don't understand what this does but I've read it has fixed the issue for some people.

[Q] New battery, at 1% for 6 hours

I decided to replace my 2+ year old Atrix battery with an OEM battery. Since then I can charge to 100% just fine (ran the battery fixing apps and did a wipe battery cache thing) but the battery discharges visibly, like down 4% for a single google search, and gets stuck at 1% for many hours. I used an app to see the voltage and it tops out at 4.2v and levels out at I think 3.5v and dies around 3.2-3v if I remember correctly. Anyway, I just don't know how long the phone will last but it is lasting most of the day. Even turning setcpu off I run for hours with a battery drain app and stay at 1%.
Using MROM-1-0.20120505-olympus. I think this is still considered CM7.
Kernel 2.6.32.59-MB860-MROM-ga43d614.
I dont see your question...
Any way I think you need a few charge-discharge cycles to make your battery statistics work.

Okay, the question is what can I do to make the drop more linear rather than going from 100 to 1 in an hour and staying at 1 the rest of the day.
And I've charged discharged half a dozen times with no change.
As you have tried, I don't have better ideas.
I like checking the voltage reading, rather than the percentage value. It usually makes more sense above 3.6V.
Delete all files (or even better copy somewhere for backup) in /data/battd/. Turn off your phone, charge it few hours after led become green, remove battery with charger connected, wait for "?", place battery again and charge it for about 1 hour, turn phone on with charger connected, check battery level, wait to 4200mV and 100%, finally disconect charger. Use phone without recharging until it turn itself off or reach 1%. Then charge it and use normally.
I did it with new battery and now works great, charge to 4200mV, 100% and discharge to 1%

I have the EXACT same problem as original poster, and i see my battery dying to 1% within couple of hours, and then remaining on 1% for rest of the day! This is misleading and most of time i have no idea how much more my phone will go on. All this despite the fact that i bought my battery paying 35 bucks to get it directly from Amazon!
Tried doing what Zeljko1234 has said in his post above, but to no avail. The problem remains as it is. Anybody else faced this issue and found a resolution? Will hard reset or rooting help? Appreciate any help

[q] htc battery acting weird

i am havin HTC AMAZE 4G
when i used to charge it before
phone used to come to 90% from a full in approximately 1 hour.
now it comes very quickly like 10-15 minutes
& also the major problem is my phone gets switched off at any battery percentage like 65% & when it gets restarted it comes to around 8% or sometimes even 4%.
if i pull out battery again restart the phone then sometimes it comes to around 30% back or any random increase in battery or sometimes even decreases to 4% & then the battery gets drained in 5 minutes & i have charge it again
battery takes more time to even charge
sometimes using DATA & charging it even takes 10 hours to charge
i dont know what is the problem
i have been thinking about battery problems
but i googled & in some blogs it shows as circuit problems too
the problem is i am living in INDIA
this phone is not official here so the service center guy wont touch it & i dont want to waste money on the battery if it isnt the problem
USING HTC ICS OFFICIAL ROM
NOW BATTERY LASTS with normal data on maximum 4 hours
help me out guys
thank u
How old is your handset? Battery life decline is normal as it ages. Without being able to inspect and test yours out all I can tell you is the most likely explanation for what you're describing is battery wear.
The original HTC battery that came with my phone only holds 2/3 of the charge it once had when new, which is why I invested in a pair of Anker batteries and an external charging station (I purchased them together in a package on eBay for under $30 US shipped). Having the extra batteries has been an excellent addition. I alternate them every few days to more evenly balance how they are wearing and to prolong the remaining life of my original battery. Plus it's great to have an extra battery to use for those times when I really need my device, but don't have the ability to plug in.
Check out the best battery thread in the Amaze accessory section for more details and comparisons.
I hav been using this phone for 1.5 years
tried using battery of my dad he uses same phone.
It showed 56% in my fathers phone
Wen i switched the battery &; started my phone it showed 15% at start
So what could be the problem then?

You're getting the different results because the batteries aren't calibrated to each phone. If you put your fully charged battery in your father's phone it shows 56%, correct? What happens when you put your father's fully charged battery in your phone? Keep in mind that when switching around the batteries neither with be calibrated to the device, but will instead show a percentage vs the battery that was properly calibrated.
Example: the battery in my phone shows as fully charged, but is worn and no longer charges to the maximum. If I place it in my brother's Evo 3D which uses the same size battery but is newer. It will show as only partially charged because his device is calibrated to his newer stronger battery. Conversely, if I put his newer battery in my phone which has been calibrated to my older worn battery it will appear to be fully or nearly fully charged for a long time before it begins to show it's draining with use.
The only way to properly test your battery would be to either try a known stronger one in yours for several charge - discharge cycles as your phone calibrates to it, or to try your battery in another device for several such cycles. Then you need to compare if there was an improvement in up-time or not. Short of taking it in to be checked on diagnostic equipment it's the best method I can think of.
Good luck!
Thank you very much for the reply
Goin to a local mobile repair guy for a hardware check
Will tell you the results tommorow
Thanks once again
Maybe you just need to wipe battery stats. One trick that works is let it drain completly and let it be drain over night and charge it again keep doing a couple of days it may just get better. But think is just battery problem not hardware related.
My Original HTC battery worked its way down to 2 hours of usable talk time. Eventually, got so bad that it barely charged on anything but a high current wall charger. Technically it was under warranty at the time...
Ordered 2 Anker Batteries w/ charger for $30, and not long after that the charger broke. It quit charging batteries.
I then just stuck with one Anker battery in my phone and the other as backup. The battery I used the most is now down to about 4 hours of life on a full charge. The least used is about 8. I try to keep the worse one charged up as a backup in a pinch and now use the good battery full time.
Just how life goes sometimes...

Yeah that Anker charger is the weak-spot in that 2 battery package deal. The damn thing is flimsy and fragile. I'm so paranoid about breaking it I treat it with kid gloves. The batteries are pretty good though. The package was one of the best investments I made since owning the Amaze. Using indelible marker I labeled them 1 and 2, and rotate their usage with my original HTC (which is easy to distinguish). This way when I'm on the road I always have one fully charged spare handy, one charging at home, and one in my handset.

Agreed!
But When I was using official ICS from T-mobile, I had the same problem, even after wiping. I even faced a funny thing. Percentage of battery in bar was different from percentage shown in lock screen!!!

[Q] What the best for the battery?

My old phone's (Xperia S) battery drains very fast (can't last for a day) after 2 years of use. When it was new it lasted about one and a half day. I charged it every day for 2 years and the battery became weaker. I don't want this to happen with my Z2. I use dock for charging my Z2. USB cable or dock is better for the battery? And when should I charge it? wait while the battery drains full or charge it every day and don't let it drain, just about half, or don't charge it full and get it drained every day. And how long should I charge it? just that time while it charge full or leave it charging for longer (a whole night, about 10h)
someone please
I dont think it has anything to do with the way you are using to charge your phone... It's just natural for the battery to need to be replaced after a couple of years as far as i know
As far as I'm aware, after about 500 charge cycles the battery stops charging to full capacity (although it says it is). So the battery quality degrades over time regardless.
the battery of the Z2 is hardly affected by how you charge or how many times its charged
itll start degrading over time
it should be a Li-ion battery (referencing the packaging instructions for Z2)

just charge normaly,
somehow i get the best life out of charging randomly, e.g. never 0>100% or simular but instead 20 to 60% increments gives me the best total life
in terms of wear, cant do anything with a Li-ion battery as far as i know
ok, better charge it when it gets as low as 30% and better not fully charge it, but 85-90% will be great for long term life. and never let it connected if it happened to reach 100%, also better keep it somewhere cold and definitely not under sunlight
It is said to live longer if you charge it from 50 to 90%.
That said, if you charge it from 0 to 100% every 2 days, or charge it from 50 to 90% ever day.... well... the end result is the same... it doesn't matter at all.
The battery already has safety over/undervoltage protection, therfore charching it as you like doesn't change much at all. You will see that a phone left at 100% in the charger will drop to 97-95% before it starts charging again.
i think the battery in the Z2 was said to handle about 600 cycles with less than 10% Battery degration.
if you charge it every 2 days thats about 3.5 years.
There is a lot of false information floating in this thread.(and lol Z2 deals with all, 10/10 loyalty) I was actually replying to this but I wanted a bigger audience to take better care of their battery, so check my thread out : http://forum.xda-developers.com/showpost.php?p=60299964&postcount=1
