Hi. After downloading the "battery calibration" app from the play store, my battery started charging extremely slow. It went from 35 to 60 in three hours after installing this app. It usually would have been finished charging by then. After noticing this issue, I reflashed the rom (eclipse rom), but the problem persists. Does anyone have a solution to this? Will I have to buy a new battery?
I use battery calibration haven't had problems you maybe looking for issues since u tried something new the reason I say that is that it only removes the battery bin file like the app says when u open it if u charge fully use it and only once not suppose to use unless u flashed new rom. All it does is remove the battery stat file from os and replaces it with a fresh one so you don't have fake stats from last rom because different ROM's usually have much different battery life. So this would lead me to belive it cannot effect the power of charge recharging your phone that would be battery, cable, extension cord if used, outlet maybe post a thread on anyone with knowledge of battery Stat removal because most do it manually without the app because it's a good thing. So the app is just convince. Oh and recalibrate your battery drain it fully take it out for 2 min put back turn on wait for it to die. Then charge uninterrupted til full this let's the battery learn it's full capabilities like when I did this my phone turned on after I reinsert battery it said 0 percent and was on lol. So the percent wasn't accurate. Let it drain to 5 percent recharge fully try not to use it while charging it takes longer to charge. I hope I helped. Sorry your post wasn't answered sooner.

Hi guys,
My xperia x10 only charges up to 98% anyone know why its like that?
Thanks in Advance
Double check that you are removing it right as it finishes charging. There are a few posts already detailing what that the x10 will stop charging once it reaches 100%, and will not resume until the battery drains below 90%.

What makes you say that??
Reason I ask is because once the phone is fully charged it will stop charging and start to drain down to c.90% when it will kick in again..
Alternatively.. if you have a genuine problem, it could be that your battery needs re-calibrating... drain it completely till the phone switches off.. then fully charge it with no use.. redrain it, then recharge it again..
i know its not going to 100% because I was watching it and using juice plotter. Also I think this might be the calibration problem. Another weird thing, is that I have to "force" it to go up to 98 but it usually just stays at the highest as 94 or 95. Also how many times do I have to discharge it.
2 or three should do it.. see how it goes.. are you using the SE charger by the way?? it 's a bit sensitive to non OEM chargers..
ya im using the SE charger
Honestly with the new batteries, you should not fully discharge them. Li-ion batteries lose their capacity if you discharge them. I have learnt this lesson the hard way with 2 laptop batteries. I always keep my x10 above 10% and it is still at 100% health.
Sometimes, when you are monitoring the battery with 3rd party applications,
the indications are a bit off.
For example, I am using Battery Status widget and I've set it to update every five minutes, so that it won't drain the battery instead of just indicating it.
So, when the phone is charging, sometimes the light goes off (meaning 100% charged) but the widget shows 97% or 98%. And 5 minutes later it shows fully charged.
So, it could be a fault to the software you're using and not the phone or the battery's at all.
When the green LED goes off, go to Settings>About>Status and check what the percentage under battery level is. If it is 100%, you're just fine.
macdaddy... These aren't li-ion
. They're li-polymer.. They don't need conditioning. But they do sometimes need re-calibrating.

Hello, I'm using Mdeejay Froyo Sense 2.4 with hastarin 7.1 kernel.
I noticed that when I'm charging the battery in Android it never goes to 100%. It reaches 96-97%, voltage goes to 4.197V and the led stays red. If, after that, I restart the phone, both in WinMo and in Android, the indicator shows 100% and the led is green.
I'm worried if the battery charging is performed correctly in Android.
I would be glad to read your opinions on that.
Thanks!

In the hyperdroid thread there is a command to "calibrate" your battery or something.
Turn your phone completely off. Charge to full - green led instead of amber. Boot back up and restart android. You should be good to go.

Both of these are good advices; and remember when switching from build to build, you'll probably have to do this a few times.
u most likely have an extended battery ... it configures itself to your other battery , thats why its telling you that ... btw , it does charge too full battery (4.197v) only the % value is wrong
oi. hasnt this been answered 1111111 times by now? ..please people use the search feature, its not just a pretty button.
Thanks!
Thanks to all of you for the advices!

To malaeus: I used the pretty search button, but I didn't find anything similar, maybe because I didn't include the word 'calibrate' (I didn't know that I'll have to "calibrate" the battery). And if you had read my whole post, you probably would had noticed that this is only the first part of it. I also wrote that: "I'm worried if the battery charging is performed correctly in Android. I would be glad to read your opinions on that."
So, with no offence, I think you overreacted a little bit.
Thanks!
The full charge battery voltage is not 4.197 it is 4.202
LI-ION charges to 4.2 volts, this is 70% of full charge, after this a "Topping Charge" is applied, this can take longer than the original charge to 70%
once the battery stops absorbing charge current this is when the battery is 100%
I would suggest using "Current Widget" to observe this, android will often state a 100% charge when the battery reaches 4.202 volts, but current widget continues to show a charge current, wait until its below 50mah or so then unplug the charger, delete the batterystats.bin and reboot the phone, that should calibrate android perfectly.
If you can live with your phone turned off for a while, delete the batterystats.bin and shutdown, then charge with the phone off. this will perform a total and complete charge with full topping charge.
Just one bit of advice... do not leave your phone on the charger all night every single night after getting a perfect calibration like this, having a LI-ION battery sitting on 4.2 volts for like 7 to 8 hours a day will simply kill the battery in under a year if not within 8 months.

Very informative! Thank you very much!
Is my battery or adapter getting broken? I did both types of calibration and I never saw a value bigger than 4.197V. Even when I fully charged the phone while off and booted to Android the indicator was at 4.154V.
Otherwise, when fully charged, the battery lasts in Android almost as much as in WinMo - 40-48 hours.

-same here. Thanks. Very informative. I noticed it when i reach 95%, it is still charging but the rate becomes lower until it returns to my normal reading (full).

Thanks for the info! I never charge my battery in Android, but I noticed, that percentage indicator readings is different between Android and WM.
One more thing, I searched for "calibrate" in HyperDorid thread, and here is what I found "charge full in windows then remove battery and charge full in android to calibrate..."
I do not get it. How can I boot Android without battery, and how can I charge already charged battery?
I copied this from another thread here, it has worked for me well.
Fully Charge while Device is Off before first boot, then upon first boot go to terminal and enter these (without the quotes) and press enter after every line.
"su"
"rm /data/system/batterystats.bin"
Ensure that Keypad Lights are on when Haret is launched and you will be healed.

I'm looking to calibrate my battery on my Epic (epic experience froyo.) I am not sure how to do it and I cant seem to find a thread. Any help would greatly be appreciated. Thanks
Charge your phone to 100%.
Boot into Clockwork recovery.
Advanced>Clear/Wipe Battery Stats
Boot up and start using your phone. Use it until it dies.
Charge back up to 100%, not interrupting the charging.
Your battery is calibrated.
my battery charges to 97% and the blue led comes on. is that 100% but displays 97?
odd...now it charged to 100...lol im so confused
Is there a fast way to drain it to zero?
Or does draining it faster than average use cause calibration to be off?

Battery calibration is covered in a few different places on multiple threads.

muyoso is right - I do that 2-3 times to define the trough and crest (valley and peak) of battery life.
It isn't good for the battery health to drain it past the point it first shuts off (so don't turn it back on until its powered externally). It also isn't good for battery health to overcharge (er, "bump" charge it repeatedly to full).
So when you get to 100% (or when it tells you its "full" - may appear as 97 or 98 - just follow the pop-up) its ready to be unleashed.
Of course, I didn't define the battery management software for the phone so I don't know for sure. But this seems to be the common wisdom contained in the threads here. Good luck.
I have found that some kernels charge to 100 and then let it drain to 96% or so before recharging to 100%. They repeat this over and over until you unplug it, so when you unplug it, its the luck of the draw as to what percentage you are at. Some other kernels charge to 100 and keep it there until you unplug it.
There should be an article in the wiki, or at least a guide for the begginers. Lol at least I havn't bricked my phone yet.
I've had this same problem even with Calibration. Sometimes I get 100, sometimes I dont. With the external dock charger, it never tells me less than 100 though on my extra batteries, but my phone is luck of draw like said before.. I've calibrated twice, and I dont have the patience to do it anymore.
OK guys,
I let the battery on my phone purposely drain completely until the phone shut off on its own. The battery status was at 3% before I let it drain, then I would imagine it went to obviously 0%. So, I took the battery out for about five minutes to cool off, I put everything back, and plugged the phone to a USB port to charge. To my surprise the battery level displayed at 67%. I think something is not correct here. Charging the phone with a micro usb cable from 0% to 67% in a few seconds is not possible. What is that, supersonic charge?
Can someone please explain what is going on here? Could it be the ROM? Is someone having the same issues?
Thanks,

The battery may not be calibrated correctly. You can download the Battery Calibration app off the market for free. Charge your phone to 100%, open the app, click the calibrate button, then unplug from the charger. After that let your battery drain completely until your phone shuts off then charge without a break back up to 100%, and you're battery should be accurate.

I'll check that. Thanks for the info.
Mine does that all the time, no matter how many times i've calibrated the battery.
Agreed. I have calibrated my battery several times and when I hook my Vibrant to charge, after a few minutes it reads 65% or something of the sort when it was at 10% earlier
Hi, I got my Defy today. I put the mobile for charging 2 hours ago. I'd like to know for what period should I put it for charging as it is the first time for optimum performance of the battery..
I tried searching the forum for a similar question but didn't find any. Please delete this post if it is a an already answered question.
Doesn't matter. May be charge it for some 2 hours more. You can't overcharge the battery - it has protection. For optimum performance, just don't drain the battery to 0%, although it has protection for this too.
Ok, thanks, its already been 2 hours since the battery reached 100% mark. Will stop charging now.

Although it is generally said that a new battery should be charged for at least 8 hours before use, it may not be necessary. Just fully charge it. However, the capacity may be lower and unstable at first. If charged too quickly, just take it out and reinsert it, and connect the charger, again.
What I normally do is charge it till 100% and disconnect.
Then every month, I'll use up the battery till it shuts itself down, turn phone off, charge it till full.
Any other time, will plug into mobile charger whenever I'm in the office till it's 100% and use it thereon.
Both answeres after mine, are for the old nicd batteries. For liion batteries it is bad to overcharge and discharge to min. Anyway, as i said, there is soft and hard protection for this, so n.p.

Under NO CIRCUMSTANCE!!! I MEAN NONE! that you allow ur batt to goto 0% or you will be effed royally by Defy. I and many others faced this. If your battery is like 15% you either charge it instantly by USB or if you have no means then just turn it off and charge in wall charger when you go home. Just don't ever let your defy goto 0% battery because if it does, you like me and many others will be stuck to M logo or white LED ****.

your lucky bro! don't do that, i was like you all naive and my defy was fine until one day, that happened to me. It didn't turn back on when i tried to recharge it only White LED or M logo.
I didn't even do any flashing or rooting of any kind on my defy then, heck i was on 2.1 eclair. So, be careful and heed my advice or one day you will regret it like I am now.

Use juice defender for added improvements from first day.. i get 2x boost , to save those extra bits when most nedded .. as for ur question , you need to calibrate your battery in order for it last longer
I advice u to charge 100% + 2hrs , and then discharge it to 10% or lower Without charging it in between !,
