So I'm running my aria on CM7-07282011-Nightly. I'm having battery issues, not battery-life issues, but general battery function issues. My stock battery died, then I bought two identical 1500mah batteries, which I have been charging with a standard Li-ion smart charger which I normally use for battery packs I build for various other projects. I just charge one battery while I use the other battery. Anyways the problem is that my phone's battery meter will never go over 80%. I boot up on a fully charged battery, and after two or three minutes have passed(when it first boots up it just shows the % it was at when I took the other battery out), the phone reads something like 74%.
I've thought maybe there was just a problem using two different batteries, so I tried charging one of these batteries in the phone and of course they stop a little above 70%, and sometimes the battery even drains while plugged into, well, any, of my 4 AC wall-plug type chargers or my computer.
I've tried wiping the battery stats, but it didn't do anything, and all the calibration methods I see say to charge until it's at 100%, which I can't get to...
I just wish there was a way to plug in an externally charged battery and reset the battery meter and force it to recognize whatever value is actually 100%....I've searched these forums and googled for two days and found no solution.
Does anyone know how I can fix this??

I'm not sure if there is anything you can do about it. There's almost always going to be some quirks with third party batteries.
A tip is never get 3rd party batteries and the batteries we use love charging so charge whenever possible because if you let your battery die before charging waste builds up and leaves less space for charging.
Signatures are fancy.
well, the phone works as long as if the battery has been charged to 100%, so I just wondered if the was something I could do...
So even if the batteries work a long time when fully charged from my external charger, there is no way to fix the battery meter? If I continue using it normally would battery stats eventually callibrate? they are good batteries...just seems like a software problem to me
Where did you buy the batteries from, E-bay??? E-bay and other on-line markets are loaded with Chinese knock-off batteries & SD cards that are fakes and/or not to manufacturer spec products.
If that's what you have, you can't expect the phone to "fix" it.
Battery stats do take a few days to calibrate, but I believe it should still show 100% when charged, if you have a real battery and not something out of spec.
I don't know what the manufacturer specs are, but a fully charged battery reads 4.2v, well within standard Li-ion open-circuit values. There is nothing wrong with these batteries....

Problem is that the percent battery available is not determined my measuring the cell voltage, rather reading a value out of the fuel gauge built into the battery pack. Li-Ion batteries have a rather flat discharge profile then crater at the end, making the cell voltage an unreliable predictor/measure of battery capacity.

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

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
Hi everyone,
Im running cherryblur 1.4d obviously rooted and unlocked. I've been running it like this for over a month now and its been great but a week ago my phone stopped charging up to 100% when I let it charge overnight. It reaches 90% and stops. I have a charger that charges the phone and an extra battery at the same time and it has worked great since I got it and the only way to get the batteries to go to 100 is to take the batteries out of the phone and put 5hem to charge in the battery slot. Please help me guys. Its not the battery because I have another battery and it won't charge fully either. I'm going crazy with this I've looked everywhere and haven't found anything
Charge your phone to its fullest capacity (I guess that would be ~90 for you)
Wipe battery stats in recovery, reboot.
Let the battery drain completely, until the atrix shuts off. Watch a bunch of videos or something.
Recharge back to full capacity, hopefully 100%

You might also want to try charging the battery with the phone switched off, when it reaches 100% remove the battery and wait for the no battery icon to appear on the screen. Then re-insert the battery and leave to charge for another hour or so.
After doing this, boot into CWM and clear the battery stats. This should fix your problem.

Mine won't charge to full unless I'm using the charger that came with it, ALL other chargers stop at 95-98%.
Sent from my MB860 using XDA App
Make sure the other chargers are kicking out at least 700ma the moto charger kicks out 850ma.
Any less than 700ma and you'll not get a full charge, a lot of 3rd party chargers only 500ma which will not work too well.

^ This. Most people don't realize that they can't use just any charger with some phones, this phone being one of them. It requires a certain amount of juice running through it to charge properly, which is why if it's dead it won't charge from a USB port.

Thank you guys I'm in the process of trying the first suggestion I'll see if it charges fully tonight
Also if you are swapping batteries, the battery stats will continuously get messed up. It will be trying to configure the two as one and that could make this a reoccurring problem for you

Oh that could be it as well because the second battery I got drains quickly (or it shows that way) and spends the other half of the battery life (8~10hrs) at 1%
Ok guys turning it off and charging fully and then unplugging and plugging again, and wiping battery stats after worked perfectly. Thank you!
For anyone who has this problem you can wipe battery stats with the battery calibrator program or in CWM and then you must drain the battery after wiping the stats.
Does leaving your Galaxy Note plugged in after it has reached 100% charged harm the battery?
From what I heard and read numerous times, you shouldn't leave a phone on a charger for more than 24 hours. I have heard many different opinions on this, but I think leaving a phone to charge overnight (6-10 hours average???) on a consistent base shouldn't harm the battery in general.
Is there "memory"?

Yep. Same with all batteries.
Hard to say how many charge cycles the OEM batteries are rated for.
From Samsung sdi...
No Memory Effect
Lithium ion batteries have no memory effect, as seen in Ni-Cd and Ni-MH batteries, from which repeated charging and discharging reduces charging capacity to an insufficient level.
Long Life Cycle
Lithium ion batteries last through more than 500 repeated charges and discharges, making them very economical.
also from other readings...
I am pretty sure that Lithium-ion batteries for smartphones cannot be overcharged because the device's circuitry stops charging the moment it reaches 100% and allows it to drop a certain % till it recharges. That's why sometimes your phone's battery % will reduce so quickly after a full charge because it is really not at 100% when you unplug it.
Manufacturers, however, will still recommend disconnecting after a full charge.
Another...
it is not good to allow your Lithiumo-ion battery to fully drain then recharge repeatedly, as many suggest, to "train" your phone...that's puts a stress on the battery and is not good.
A low % (15-20%) then recharging to full one time will reset the meter and make it more accurate but not lengthen the batteries life.
all that said...I plug mine in at night and unplug in the morning.
This link talks about the Samsung battery and charging. It sounds educated on the issue but who knows....

Summary
1. Use wall charger not computer
2. Unplug when charged
3. Don't recharge until battery is below 10%
I put the phone on my desk dock every night whether it needs it or not. I do find myself topping it off too much also.
,this is how i calibrate my battery,before i have 45min of standby it will decrease from 100% to 99% but now it is 2hours & 34min before it go from 100% to 99%,i felt the drain after 2 weeks of overusing my phone (1week playing paladog and 1 week flashing different roms,kernels and theming my phone with different launchers),
- Charge your phone to 100% while it’s on.
- Unplug it from the charger, power off, then charge for 15 minutes with it in a powered off state.
- Unplug charger from phone. Power it on, and then charge 15 minutes while the phone is on.
- Calibrate battery using battery calibration by NéMa then unplug charger reboot.
- Power on, charge for 15 minutes then unplug.
- Finished.
note: deleting battery stats(calibrating) don't increase your batterylife said by others and it is just a placeboo and i believe in them,but it fix my battery drain so why don't we give it a try,there is nothing to lose,battery drain is so annoying.
,thanks to NéMa for the awesome apps,
,thanks to jgezau for his thread as my reference,

That was from LEWA OS, one of the best rom at that time...:good:
First and foremost, a Google engineer debunked the idea that batterystats.bin has anything to do with how the phone charges. By deleting it, you're actually inconveniencing yourself, as there will be a short period in which you won't have accurate stats.
Secondly, the O1 has a lithium ion battery. Lithium ion and lithium polymer batteries don't need to be calibrated, as they have no "memory" effect (you can read more on that here).
Moreover, these batteries have built in charge circuits that protect and regulate the battery. Ever wonder how the phone knows the battery temperature? It's pulling it off the charge circuit. That same circuit also prevents the battery from ever being overcharged or discharged fully, which is why that convoluted guide about calibrating your battery by draining it to "empty" and then recharging it to full doesn't work. Worse yet, intentionally draining your battery is actually counter-intuitive, as lithium-based cells wear more as their percentage of discharge increases (you'd be hurting the battery in your effort to calibrate it).
Your instructions aren't detrimental, so if it works for you, go for it. However, based on my understanding of these batteries, it seems to me that this procedure is inconsequential.
Besides, a new battery for the O1 is only $6 USD on Amazon or Ebay.
