How can I calibrate my unrooted phone
Sent from my Nexus 6 using XDA Free mobile app
You can't. Even if you are rooted.
Run your battery all the way down until it shuts off. Charge, uninterrupted, until fully charged. Voila! Battery calibrated.
Battery calibrating apps/techniques have been useless for quite some time.

My phone has gone through many charge and shutdown cycles and not even this has changed my 5% shutdown.
Have you tried leaving your phone plugged in after 100%? Let it trickle charge for an hour or two.
The battery 'calibration' stuff that people do is what android does automatically after getting to nearly full charge.
It hasn't been needed since gingerbread.
I have had this issue happen a few times, what I do is plug it in to turn it on , then try to run it down till 0 and then put it on charge while off till its 100% and leave it there for a few hours. Then after a few cycles, this occurs again. I dont charge in the middle, always charge at night until 100% and 30 minutes beyond that.

Ok so I have my nexus one and I did the battery calibration more then once.. I had a fully charged battery and took it off the charger for 15 minutes? Went from 100% to 95%
I come back on the computer and plug my phone up to the USB charger. So I come from 95% to 93% how is that possible..?
I am going to try my spare battery see if it does the same.
I am running the latest CM8 test 5.
It cuts of battery when is it 100% charged, waits till its gets to 90% then charges again

Really, I see..
My 4-week old rooted NC (1.1 / Autonooter 3.0) has been plugged into the BN charger for a few hours. The battery level shows 98% yet the LED on the BN charger is green, strongly suffesting that that's as far as it's going to go.
I've not let my NC get much below 40% battery level without recharging.
Anyone else seeing this behaviour? I realize that rechargable batteries have a finite life span, but I'd sort of like my NC to last me a couple of years.
Perhaps I should let the battery get below 10% before recharging...
There is no such thing as memory effect. Discharging your battery is the worst thing you can do for it. If it says 98% is the most it can do, then your battery statistics need to be wiped. You can get a more accurate mapping of % to charge level by doing a full charge to discharge cycle, but this leads to premature battery death, and I do not recommend it.

Thats normal, the charger operates in low-current mode and will keep charging till it gets 100%. Let it plugged for another 1 hour and you should see the 100% full charge then.

You dear sir are correct, most devices have being doing that for awhile.
Even my pro2 and diamond would take 2 hours to get from 98% to100%.

When I charge my phone and it says the battery is full and 100%, but after I unplug the charger, I only get 98% of battery. It is not really a problem but i'm just wondering if anyone else has this also.

Seems to be phone battery calibration, happens to me too. Try not to unplug the charger immediately after 100%, let it overcharge for few minutes more.

Also happening to me... It's because battery calibration...
This is the normal behavior of overcharge protection.
imagine you battery is charged till 100%, the overcharge protection now disable charging till the battery is loosing a few % of its charge, but the "battery memory" doesnt recognize this respectively doesnt refresh its state so your battery indicator will always show 100% until you unplug the phone.
if you unplug the phone at 100% it might be, that the battery memory is refreshing after loosing one more % of charge and now recognize, thats it wasnt at 100% at all and show you the current charge.
e.g. if you charge your phone when its off-state, this behavior shouldnt take place and the phone should charge till exactly 100%. important for recalibrating the battery.
Here, if you have root use this
https://market.android.com/details?id=com.liteup.calibratebattery
You can also load up clockwork recovery anf clear battery stats.
If no root access, fo the following.
1.Power on let fully charge
2.turn phone off while still plugged in
3. Remove battery and power cord and push power button for 5 secs
4. Replace battery amd power cord
5. Let fully charge again.
Once charged, power up while pluged in, once phone is fully loaded un plug and monitor battery,
None root battery calibration should be finished.

When it happens to me... I inmediatly replug the charger and wait... the second time I umplug I get 100% and It seems to repair the issue for the future charges.
i noticed this too! sometimes i do get 100% after charging. But most of the times its 98% immediately after unplug! And i have my battery calibrated too!:/
same issue
any solution for this guys?. I've calibrated my battery so many times and it is not fixing the 98% charge when unpluggin
mine's not...
try screen-on charging...
go to settings>deveLopment>check stay awake(charging)
if you're in Gingerbread version (2.3.4) when battery reached 99%, you"LL need to wait 1 more hour to make it fuLLy charged...
that's it!
tried and tested by most android users...
just charge it without using to avoid excessive heat of your device... :good:
What about first time using battery? Charge the battery 100% first or let it drain to 0% then fully charge?
I bought 2400mah battery, but cant get significant performance, fully charged first time use..
I think you were ripped off.
we will miss you Nicholas.... /s
If your going to buy an aftermarket battery. You get what you pay for. I ordered a mugen 1800mah delivered in 4 days from Hong Kong. My synopsis Bloody brilliant!
Waiting for my Jiayu g2s to be delivered
I do not understand why the percentage of the battery as soon as I turn on the phone after a full charge immediately indicates 98% and not 100%, even if the display shows off the full charge as soon as I remove the charger.
It's probably because your 100% battery level is nearing on 99% and every reboot, based on my experience, more often than not consumes 1%, maybe more, hence, 98% battery left.

I'd suggest varying how you charge the phone; 1) with the phone on 2) with the phone off
My (albeit anecdotal) experience is that when charged with the phone on, and left on the charger longer than when it says 100%, it's doing a 'trickle' charge, which then seems to charge it completely. Again, anecdotal, but it seems to me that after charging it numerous times with it on, then when I charge it turned off it seems to do a *full* charge.
ymmv
maybe I explained myself badly. in the evening I put the phone off and off. In the morning as soon as I accrue it, instead of marking 100%, it will score 98% .If it is when I unplug it from the charger and it is still off and it is 100% .
Hello, lately I can not charge the battery more than 98% and in some cases 97%
I already use the method to calibrate the battery but it continues the same.
Only if I disconnect the charger and reconnect it reaches 100%
Any solution?
In my case the same thing happens.
I have not found a solution yet.
Charging it off turns it 100%, turning it on 98% and then on to 100% again.
in 5 minutes it goes down to 96%, and then the battery is safe.
I have a good time to use the battery, since I stayed 18 hours away from the charger.
