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.

...sorry I haven't seen you already answer
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?

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

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

Getting my replacement today and my current phone has suffered from bad battery, so what is the best way to charge the new one please?
Thanks
I charge mine overnight most nights, and it gets better over time. It took a couple of weeks before I started to get really good life out of it.
Based on what I've read, you should charge for at least 3hrs and then drain it completely.
But I'm pretty sure you can still use it right out of the box
I don't think any extra/time specific charging is needed for Lithium batteries for the first charge. Just unplug it when charging completes. But if you calibrate the battery make sure you fully drain it before recharging it.
Regards.
It doesn't matter, there is no need to bother about how to charge modern li-io batteries.
I don't think modern batteries need any kind of special first charge routine....................but I still do it anyway

Just read about this earlier on my local samsung officially site and yes ever since it is lithium battery its ok to charge anytime afor how long even it already 100% and still on the charging mode ots automatically cut off the power supply inside. But i do still charge like 4-6hours for the 1st time
sent from my 2.3.3|dxjpe DJGTabs7
Just charge it to full, and then start using it, charging it overnight does nothing, the BMS will stop it from charging when the voltage coming from the battery is considered 100%.
Lithium batteries do not suffer memory effect like Nickel batteries.
The old charging practices cause more damage.
Lithium batteries should not be overcharged (Same as NiMh)
Lithium batteries prefer to be fully charged. If they stay on empty too long, they get damaged. Using the charge up before charging the battery can damage it, the optimal is to charge it before it gets low. Regardless how well you keep them, they have a predetermined life span, so they will stop working after a few years.
Thanks everyone I am going to charge it for about 6 hours, then calibrate then fully discharge and fully charge, Until o2 unlock it :'(

Completely pointless....once it reaches 100% it stops charging.
Someone pointed out the same thing you all said i.e.modern li-ion batteries don't have a memory, they don't need to be formatted, however extreme conditions aren't healthy for them e.g. leave it completely depleted or completely charged for prolonged periods of time (days?).
i just charge mine to full the 1st time i get it while it is off and i am fitting screen protector etc
i then use it till its about 10% and charge to full
i then use it as normal and top up charge whenever
it may not be needed but batterys have always been good for me and its a little routine i seem to be stuck in lol
hope your new phone is decent and you enjoy
Is anybody having problems fully charging the battery to100 percent? I noticed the battery life has gotten worse since I owned the phone. it would always charge 100 percent. Now it only charges to about 98 percent. I made sure all active apps are turned off and running apps as well turned off. I will turn my phone off at least once a week and fully charge it overnight. I notice after doing this the battery life Is always worse.

Don't believe your battery bar...
Check the number of volts your battery has... its a much better indicator

The phones charges to 100% and then it stops charging if left on the charger. So you will lose 2% or 3% of battery power before it start charging again. This is designed to help keep the battery healthy as its usually not a good idea to leave the phone charging for long periods of time.
I charge mine until the thing on the status bars pops up indicating "full" and then remove from charger. The "full" indicator pops up about a half hour after the phone shows 100% which I find odd however... That also might be a battery health thing as they probably don't want you to charge it to absolute max, so maybe by saying 100% whens its more like 97% that it helps with battery health...

It trickle charges for a while after hitting 100%, then shuts off giving you the "unplug me" notification, drains a few %, then back to trickle charging.
In the morning if you unplug it and then plug it back in it will be fully charged in less than 30 minutes. To the full 100%.
When I first got my phone I was playing with it so much (and testing out the true battery capacity) I was often plugging it in at night with a nearly dead battery - which takes longer to fully charge overnight. So by morning it had only stopped charging an hour or two earlier so it still showed 100% for a while. Lately its been at 60-70% so by morning it has been done for 4-5 hours. So after booting it often shows 98%. No difference in battery capacity, just a longer time post-charge where it has drained a percent or two.

Thanks for all the replies. I guess it makes sense. it just seems to run down a lot faster everytime I turn the phone off and back on the next day. It must just be me

Try the unplug-then-replug routine one morning to restart the charging process. See if it is better that day. If it is, you are probably running into the same problem I talked about in my last paragraph.
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
How many of yall use the fast charger overnight? I do have a BlackBerry charger (850mA) which takes like 4.5hours to fully charge, so I use that to charge overnight.
Is it okay to use the fast charger for overnight charging?
I do. I have the phone for a short time (2-3 weeks) But no problems yet.
i charge in the morning for 30min -1h or in the evening to 90%+. i always charge to around 90% for batteryinfo to reset.
While the poco is charging the phone says its better to charge often short instead of overcharging the battery.
To your question, it should be alright to charge overnight. Just make sure it has good ventilation (not on your bed or under things.
If you want to preserve battery life cycle, then no. The closer to 100% you get, the worse it is for battery.
I prefer charging at night and in the morning if it's below 70%.
Otherwise, I will charge in the morning before work, and in the afternoon.
I only charge to 80% where possible
I had a bad experience with LG flex 2, I always used fast charger to charge overnight and with 2 years I got 2 dead batteries. Now I use Battery Charge Limit app and slow charger overnight. It stops charge at certain level like 75%. And that lasts for a full day for me.

I used to do this. But I've noticed that on days I don't fully charge the device, I have to plug in again mid day / evening, ending up using more than 1 battery cycle. If charged to a 100% at the end of the day it'll still have 20-30% left

This could be the result of a few factors.
Does the phone automatically cut off power when fully charged. Most new phones do cut off power or at least slow down the charge rate. If it does not, overcharging is one of the worst enemy of battery longevity/lifespan.
After power cut off, does it resume after the power gets below a certain level, or does it charge at a slower rate. Charging at a slower rate helps but it is still overcharging, so the slower the better.
As I mentioned previously, battery temperature. Fast/quick charging doesn't actually affect battery longevity/lifespan as long as the heat is controlled properly. A phone charging at 50 degrees Celsius at 5 watt (5 volt, 1 ampere) will be dead (unusable) faster than a phone charging at 35 degrees Celsius at 18 watt (9 volt, 2 ampere).

If by battery cycle, you mean how many times it is charged, then true.
In terms of battery longevity/lifespan, then it's not very good.
