Flashed device, battery resetted 100%

Hey i flashed my device with the battery at around 80%.
after the flash it was 100%...
so this means i just lost 20% of my capacity? how do i fix this?

I don't believe you have lost capacity. It's only your gauge that's slightly altered. If you recharge your device fully(and about an extra 30min) you should have the regular capacity

How could going from 80% to 100% equate to a lost ???
it's posible that you'd gained the extra charges while the flashing process was going on ( because it was plugged in ?? ) ... if it wasn't ... no idea why

If i understand the post correctly they are equating am 80% to 100% a loss for 2 reasons:
1. because he would have lost charge while flashing due to the massive battery drain.
2. because now he is stating that his 100% is really only 80%
but i would probably just leave it charge overnight and you should be fine, the gauge just sounds to be off, it shouldnt be a true loss (unless the battery is bad)

Is there any other way to sync the battery with the device? I been trying a full discharge then charge.
I am using a mugen extended 3000mah battery and at 15% 10% and 1% it will stay there for some time before it starts to go down or turn off completely if it is reaches less than 1%.

I don't think you've lost capacity.
I believe you just did a quick check before flashing (and it was already charging before you started right?), and the battery gauge wasn't updated. I had this a couple of times while recharging. I take a quick look and think "this is gonna take another half hour". Five minutes latter I check and the charge led is green again.
Sometimes the battery metter lags a bit, you have to check it again to be sure when charging.
At least it happens to me.

a few cycles of full charge and discharge should put the battery meter in check...

Alrighty. I have done three so far. It has gotten better then the first time I got it. But its not perfect.

is it safe to discharge it to 0% so that it will shutdown? or what?

Battery recalibration after ROM update

http://www.nexusoneforum.net/forum/nexus-one-faq-how-tos/5625-calibrate-your-battery.html
RECALIBRATION:
A recalibration is mostly needed, when dealing with different kernels (ROOT!). Most custom recovery images provide the option "battery stats wipe" under the menue "Wipe".
Here is how ya do it!
1. Enter Recovery Mode
3. Enter "Advanced"-Menue
4. do "Wipe Battery stats"
5. reboot
Calibrate the battery by completely draining it until the phone completely shuts itself off.
Turn the phone on again and let it shut itself off one more time.
Then charge your phone while it is off for over 8 hours.
This will fully charge the battery so that when the Android is turned on, it now sees the battery as full.
It is recommended to repeat this process at least one more time.
You should see a significant increase in your battery’s charge life.
Calibration of a battery can be done at any point and a maintenance calibration is recommended every month.

Thanks for this useful guide

Hi,
Your posted information doesn't sound true for me. Why should recalibrating increase the battery life? The battery is full when the end voltage is reached an no more charge can be taken (4,2v @ lipo) and it is empty if the minimum allowed voltage is reached (should be with Deffy's technology 2,8v?). So why should recalibrating increase battery life?
Greetings, Jo

It's well known that this procedure will indeed produce better battery performance. Most devices have a similar procedure. Even HTC has given some calibration procedures in order to improve battery performance.

How do you enter Advanced Recovery? I can get my phone into recovery but that's all.

Hey,
You have to user Clockwork MOD recovery, and then when inside it go to Advanced, and you will see the battery wipe option.
cheers

lion battery recalibration/recondition was already there long before android even existed...

Since I flashed several ROMs I tried this and I am happy! Battery consumption seems to be better after this workaround. I'm on 1.3 Ghz @ 72 Vsel with my Defy and easily reach an uptime of 2 days, mostly a bit more..
Thanks again!

There will be almost no impact on total runtime, just the percentage meter can become more accurate by "calibrating" the battery. In addition to a complete discharge (I do not encourage you to discharge more than ONE auto-off, you shorten the battery life by discharging below 3.0 V) you need to have a nearly constand discharge current on most phones for this calibration to become really accurate.
What is the effect? Well, not much. Your phone just knows better how much battery is left, so maybe the "empty batt" message @15% comes later. The usage time and the auto-off threshold are not impacted at all.
When we are talking about a battery that has been put away for months without use, you may be right. One charge-discharge-charge cycle may bring back some capacity. But this is not true for any regularly used battery.
If you care about battery life time (in months/years, not a single charge): Charging above 4,0 V has a great negative impact on it; Constantly holding the charge @ 3,5-4,0V may nearly double the life of a battery but you can only use about 50% of its capacity this way.

I'm not sure if calibration/full discharge is necessary/recommended. From many readings calibration is not necessary for lithium battery. Actually it is recommended against full discharge as lithium battery has limited full discharge/recharge cycles.

after doing research on all methods to recallibrate checking pros and cons finally i got the answer brothers...its very simple no need for cwm or drain full abttery kill your batery download recallibrate delete batterystat.bin....all fake bother....just do a simple step remove your battery for 2-5 minutes and than on it....you are recalibrated....simple

take out battery for about 10 minutes. And then try to charge again.
If you will see same problem i think you need to buy new battery.

[Q] how to make the battery charge life longer

hi friends
i wanna ask a question about how i can make the battery charge life longer?
thanks

It depends what type... I know one where you'd almost have to drain it but not all the way then fully charge it would make the battery life longer than having its life cut short.....
Sent from my S using Tapatalk

Try this technique which I used on SE XPERIA X10:
Charged the phone to 100% and while still plugged to the charger remove the battery wait 5 seconds put the battery back unplug the phone switch it back on and plug back into the charger. Ur battery should now show 88% charge not 100%. will wipe the battery stats as well when I will fully charge to see if it makes a difference.

Need to fully discharge the battery at least once a month until the phone off .. then you load up to 100%, and doing what was said above, remove the battery, and turns the charge again for up to 100%

WTF?¿??why are you opened a repeated thread? if in this section there is an entire thread for talk about it..

In spite of reading a bit one sees immediately

A simpler way is just to use Battery Calibration app, it can be found on the market.

Is it a bad thing to charge the battery at 50% still?

wow is what i am interested , the method above i have tried but no obvious difference. so the app is really that helpful ? have you ever tried it ? i don't want to install then uninstall.

battery question

hi, is that tru, that is better to charge your device the first 3 times 12 hours? because i know that with the new batteries don´t need that like some smartphones?
and i hear that is better if i discharge totally the battery and then i charge until 100% so if that is true, that means that is not good to charge like 1 hour?
thank you.

It is actually bad for the battery (Lithium-ion or Lithium-polymer) to discharge it completely. You should always aim to grab the charger at around 20%, refill to 100%, then remove the charger.
Newer batteries don't worry so much about 'trickle charging' once the battery is full (and newer, more energy-conscious chargers may actually switch themselves off internally to prevent wastage and damage to the cell).
If you have a brand new phone, the first charge should be for 12-18 hours, preferably without use (if you can bear it). You won't see the maximum battery life from the cell until you 'cycle' (charge/discharge) it a few times, but after a week or so you should get a profound increase in battery life.
Just remember - no lower than 20%
Hope this helps!

NO! This is bullsh*t that u need to load battery 12 hrs, better take ur battery off and throw in sh*ting bowl and w8 sb to go toilet or you can urinate too and see, what happen! u can try it high voltage battery too, i hope that result is same..

for first time it is good for the battery so that it gain its max capacity..so when you get the phone first charge it to 10 hrs.and dont use at that time and also charge your battery only when it goes below 5% because every phone is having its charge and discharge life...

I usually have my charger connected to my phone, is that a bad idea then?
No special reasons to do it but if must go out suddenly and i don't have enough battery...

Yes it is....your battery ruins day by day..just charge when the battery level is below 5%'...
Xperian8~ click thanks if it helps...

Thanked! My old cell phone could still power on without a battery using the charger, that's one of the functions which i miss on this smart phones.

[Q] About Charging Battery

Charging phone whenever i want will decrease battery life ?
Example my battery 80% but i want to charge it to Full , is it ok? ( just an example )

Not like that as far as i know. U ll have to charge and discharge the battery completely for the first time after purchasing it, in order for a better battery lifetime.
Hit thanks rather than typing it now Free

The new batteries comes out without the memory-effect. They don't need to be fully discharged and fully recharged.
The best warnings I can give you are to not let it go below the 5% of charge and to not let it reach hot temperatures.
Sorry for my english .
