Hi bought HTC One X(international) a week ago,and have a question about the battery calibration,when I unpacked the phone it had battery on around 50% then I used it until first battery low on power notice,I think it's about 15% battery I don't remember,then I let it fully charged,and my phone goes for about a little less than 2 days on standby with 15min calls,some music,games a little,but mobile data is always off so is wifi,i only turn them on when I actually need the internet connection,for web browsing,now my question is, is my battery properly calibrated,because I have read that you have to fully charge the battery before first use(that I didn't do,but when I put it on charger I didn't disconnect it until full charge),so that system could record battery capacity,otherwise it will record incorrect battery capacity,and battery will last shorter than it has to last,I supose it will record incorrectly,battery full notice,and will notice that battery is full to early thus resulting in shorter battery life,now knowing my use of the phone,can it last longer,and do I need to re calibrate the battery?
There is no such thing as battery calibration. Your battery will be fine, nothing needs doing.

Man, I hate starting new threads! I did a simple search and couldn't find this problem anywhere else, so here goes:
Earlier in 2009 I bought an extended 2400mAh battery for my Kaiser (8925). Everything is working just fine, except that I noticed that the phone doesn't seem to notice that the battery life is much better for this new battery.
What I mean is: after a few hours of usage, the battery level drops at a normal rate.
Once the phone tells me the battery is almost dead (and sometimes the phone will shut off if I ignore this), I can shut down the phone, remove the battery, wait a few seconds and then replace it and boot back up the phone.
At this point, the phone will usually tell me that the battery is at 33% to 36% charged. Notice that I did not charge the battery, I just removed it and put it back in.
When I first got the battery, I cycled it completely three times in the phone, removing it twice and replacing it to ensure that the battery was completely drained before charging it to 100%. (Yes, I know that is only recommended for metal-hydrates, but I feel better doing that anyway).
On the top-end, it usually takes about two hours to charge the phone from 30% to 99% via a standard USB2.0 connector.
However, the phone will report that the battery is not fully charged for nearly an hour after reaching 99%.
I know what you are probably thinking; Why is this guy complaining about his battery performing better than his phone reports?
Well, it IS kind of annoying. I would like the phone to properly report the remaining percentage for my own benefit. I really hate having to guess at how much time I have left before I need to drop it off at a computer or wall outlet while I find something else to play with for three or four hours.
So... Does anyone know how I can convince my phone that the battery is pretty awesome and to start reporting the actual battery life?
I just got some new batteries for my i-9000. I am wondering, I have always heard LIthium batteries do not like to be fully discharged. I want to perform a calibration on the new battery, but all the battery calibration apps say
1.Fully charge the battery
2.Press calibrate battery button.
3.Run the phone fully flat until the battery dies.
4.Fully charge the battery to 100% uninterrupted.
Now, step 3, going all the way until the phone dies, is that a good thing to do or a bad thing to a new battery?
Letting your cellphone's battery drain until the phone dies is a normal thing that won't damage your battery, because the battery won't really go to 0% charge.
Cellphones always shutdown it-self when the battery levels get too low (like 3%), to avoid the damage it would do in the Li-ion battery if it would go to 0%. So you have nothing to worry about.
yeah mine shuts down around 2-3% percent for that reason. You'll be fine.
thanks.

just doing it once when you get a new phone or after noticing horrible battery life on a newly flashed ROM can work wonders
other than those times, I only let my phone get to 20-40% before I plug it back in
I Use BOS Gingersense Port From Kingdom, My battery is good and i didnt do that whole discharging,recharging crap.
calibration works for me...
Calibration even worked for me too, on my Galaxy 3. Previously i was getting backup of only 1 day, but after calibration i get around 1.5 days. I know its not much improvement, but still its worth.
And you don't need calibrate frequently. Just once in two weeks is fine. And I've heard that deep discharge once a while is infact good for the battery. Correct me if I'm wrong.
waiting for phone to completely die right now. One question though can I turn on phone while charging or should I just leave it off after dieing?
I called Sammy, they told me letting the phone turn off by itself because the battery can't power it is bad for the battery in the long run, they said you can't really see the bad effect that time, they told me, we have learned on are testing that when you see the low battery message pop up that is where you need to charge the phone, that warning is where the calibration starts, now draining it to the point that the phone turn itself off is bad for the battery. Do you believe that?

Only if you leave the cell empty.
It's best to recharge a cell as soon as possible if you have discharged it.
Discharge/charge cycles should be kept to a minimum, ie when you first get the battery, when you are sure you need to recalibrate, and when you've got no choice.
Top up charges are best for lithium batteries.
The charging circuitry in the phone should protect the battery from over discharge. It also protects the phone from overcharging. However, just like a spring, it's the constant charge/discharge that damages a battery. I would not run it down every day but it should not damage the battery, only cause it to wear out faster.

Try to avoid frequent full discharges. Occasional full discharges are okay.
Lots of uncertainty here, lol.
A new Li-Ion cell will output ~4.2V when fully charged and ~3V when it is totally discharged. Every single smartphone I've owned would shut down before the cell dropped below 3.5V. Draining your phone's battery until it dies will not hurt the battery or your phone. No worries about batteries catching fire.
Repeated or frequent full discharges will wear your battery out much faster, though.
i heard something about battery training
maybe it helps for the battery on the htc one x
charge youre battery for 8 hours whit youre phone on
then turn of youre phone off and charge it again for 1 hour
turn youre phone on for 5 minutes then turn it off again and another charge for 1 hour
anybody know if this works?
There was something similar announced from HTC for the desires. However it really screwed with the battery stats and was only detectable when running custom roms and the UOT battery percentage mods. Mine used to shut down at 20% sometimes, other times it would make 10% which was frustrating. A LOT of people had issues. Left alone on my sensation and that was fine. I would avoid imo.
Want to get the most out of your battery fully charge it with the phone off and fully discharge i a few times when new and the once a month/fortnight after to help it.
ok im going to try that one to thx
A full discharge is bad for Li-Po batteries, but it might be good for Android battery calibration. I would not fully discharge the battery on a regular basis, it will damage the cells.
Hello,
I've read the threads about battery in the desire, BATT FIX with new kernels etc but can't really find a definite answer for my problem.
I bought my phone 18 months old and from the beginning it has shut down at about 20%. Tried the battery thing with charging, on/off, charing again etc, wiping battery stats etc but it doesn't seem to matter. So, I thought I'd just buy a new battery and be done with it.
The new battery arrived yesterday (actually, it's a used battery from customer returns but seller tells me it's been tested to be in mint condition). So this battery shows 3% when I first start up with it, "good, this seems to work" I think. But when at 75% the charger indicator (LED light) all of a sudden turns green and battery % jumps straight to 100%. I do the battery calibration trick with on/off charge and wipe battery stats. Stuck at 100% for some time as reported by others trying this "trick", have been using it all day and it shuts down at 25% even worse than the other battery...
The best voltages I've seen on this supposedly new battery is 4,144 and somewhere above 3.5 (nowhere near 3.2 and 4.2). What strikes me as odd is that I get very close to the same values with my old battery so I'm starting to think that maybee both battery are good but the phone reports way wrong values...is this possible?
Battery life with phone and data connection on, 1 gmail account but disabled backup feature (no GPS, BT etc) gives me -5% after 10 hours standby and I can use the phone for browising, light gaming for about 3 hours and 40 minutes before it dies (more or less constant usage at very low autobrightness levels and Turbo 3G enabled).
If someone has some insight into this it would be really helpful before I contact the eBay seller for this particular battery.
Regards, Olle
Same thing
My phone shuts down at 35% now... Is that a problem with the chipset or what? Only with Alex-V's calibrated kernels my phone shuts down at 0%, and sometimes it decalibrates too, but after calibration is Okay. I wonder if i need a new battery or my chipset has issues.
Hi! My old battery was inefficient (45% health at AccuBattery) and it swelled so I decided to replace that one. Everything goes easy because it wasn't my first battery replacement in this phone but just after replacement I noticed that the new battery is draining fast also. I was operating on MIUI 12 by Xiaomi.eu, so I decided to rollback to Stock ROM with MIUI 11. I flashed it with MiFlasher (With full wipe). But still new battery was draining fast (51% health) in AccuBattery. Then I want to make sure if this new battery is actually new, so I bought another battery, but this time from other company with good rating and replace it. And this do nothing because the newest battery phone is using only with around 50%. I tried to recalibrate battery once, I drain phone to 0%. And then I want to charge it to 100% without turning it on, but it turns on automatically and it gives no effect.
What should I do now?
Only one right way is to measure battery capacity with special charger. Something like this.
Drain battery to 0%, turn phone off, connect through device, and charge to 100%.
