HTC One X - Battery Calibration after flashing

I'am confused about calibration of the battery after flashing a new ROM.
Do I have to calibrate it every time after flashing or, is it already calibrated?
PS. I wiped out every thing on my phone before flashing a new ROM. I think it would delete everything including battery data and that means it is calibrated, right.
To calibrate the battery, can I use one of the applications on the android market. ( there are a lot of them)
Thank you in advance
PS2. Are there other ways to calibrate the battery?

I had exactly the same thought today as I was flashing my ROM.
I guess it's going to be finding out where the battery stats are stored, if they are somewhere in the areas that get wiped during a ROM flash then yeah, we are probably going to have to wipe the stats at full charge.
I will be watching this to see if anyone else replies.

You should calibrate after a flash, just charge it overnight so its completely full then then use battery calibration app from market or do.it manually using Es file explorer, go to data/system and delete batterystats.bin. restart phone and it will generate a new batterystats.bin file. Job done

Thank you very much for the answer.
Actually, I think that this topic should be warned for new users (like me) so that they will not confuse about the battery life.

There's really no need to wipe the battery stats. A google engineer explains it all here:
http://www.xda-developers.com/andro...-battery-stats-does-not-improve-battery-life/

Hello, the person at Google talk about the "wiping battery stats in order to improve battery life."
That is not the good description.
It should be : "wiping battery stats in order to improve battery calibration."
I would be interested by asking Dianne Hackborn how she explains the fact that the battery level goes straight from 85%~90% to 100% in some HOX ( Mine does ).
"Technically" the Li-Ion just can't have this behaviour at "low rate charge" ...
so this charge graph behaviour is a software behaviour due to some code that adjusts the charge at 100% when battery just can't charge anymore.
Here is an example of a "standard" Li-Ion charge with a good charger :

( Source, not a phone battery but a Li-Ion battery ... )
The black curve is the one we should get on our devices ... I don't get this.

So just deleting the file and rebooting at full will do it? Is there any benefit to something like the following procedure (found from another forum)?
1. Once your phone dies plug it into your HTC charger, (DO NOT TURN IT ON)
2. Let it charger fully (about 3 hours) until you see the light turn green, unplug the phone
3. Turn on the phone on but do not mess with it. (no checking email, messages, etc) let it sit for about 20 to 30 min
4. then plug it in again but let it continue to sleep (about 30 min)
5. once the light is green, unplug and your finished.

I ask because I found it on another forum. My battery life is pretty ****ty right now and I'd like to fix it.

The file is reset when you reach full charge. No need to do anything.

Good info, thanks!
Btw, do you have any info regarding my above inquiry about actually letting the battery drain? Is there any reason that would help moreso than having the file reset?
Alternatively, do you have any other ideas as to what might be causing my (at least perceived) poor battery life? I'm getting maybe 13 hours on a charge with pretty scant use. CM10 Nightlies.

The file and it's contents have no bearing on battery life. It's only there to record which apps and services have been using battery.
If your battery life is short, it's likely you have something preventing the phone from sleeping.
Example; when I'm in China my battery life sucks compared to Hong Kong. I often notice the synching icon in China. I suspect Facebook sync is not timing out (its blocked in China), preventing the phone from sleeping.
Better battery stats from the play store can help you determine this.

Battery dead overnight.

So, I had about 50% juice when I went to bed last night. Woke up to see phone dead. Had to plug in charger to start it as battery was fully drained.
So what causes such sudden battery drop?

It seriously looks like some apps have been doing some heavy tasks while youre sleeping..
Check with your nearest dealer. Then contact samsung if you think your battery is faulty

Battery doesnt seem faulty at such an early stage.
Best solution. Download BetterBatteryStats and check out what is draining your battery
Its the solution i would do with myself

I dont even have much apps installed yet. & battery life so far was really good until this morning. Seems quite stange. Has it happened to anyone else?

I don't think that could have been any apps to deplete the battery that quickly. I mean, that literally did a nose dive. Ever heard of Ghosts?!? DunDunDunnnnn

Does battery reset itself somehow?

Yes, an app or some apps drained your battery No other solution possible mate . As mentioned before install BetterBattery Stats and cpu spy and check for unusal app behavior.

The thing that surprises me is that on the steep drop, the green border-line is missing. It doesn't look like drain; it looks more a short circuit...

Its actually not a drain. Its a sudden cut off.

In your case, don't bother with better battery stats or any other that other crap people are suggesting. I don't think the majority of the people who read your post bothered to look at the attached image (or didn't understand it.)
During the time that your battery dropped off, android wasn't even active (as no battery stats were logged.) That drop-off looks to me like some type of system crash or something rebooted your phone into recovery (or download) mode and left it there until the battery died (causing a power down.)
I can't tell you WHY that happened, but I can't think of anything "normal" that would cause it. I used to see something similar when I was doing kernel work on a specific samsung tablet if the user had one of the so-called supercharger scripts installed. In that case, the kernel would panic (wifi bug) and the script had re-written the kernel parameters to cause an infinite loop instead of letting the kernel panic reboot the device. The result was that the device would get warm and drain the battery until there was no more power.
Recovery meant charging the device first and upon finally getting it to boot, the battery page would look similar to yours.
Another possibility is that your phone hit what it THOUGHT it was around 46%, but the battery stopped giving juice.
In your shoes, I'd do something I usually tell other people never to do: Purposely run your battery down below 40% to make sure the same thing doesn't happen. (If it does, consider restoring your phone to stock, testing again, and possibily calling Samsung.)
Good luck

Thanks for the prompt reply.
Meanwhile battery life was normal throughout the day. I will follow what u suggested n if it acts weird again, I'll have to go to samsung i guess.

[Q] Battery issue

I have my i9250 on CM11, fancy kernel and one of the latest twrp recovery.
I just changed a battery from original one (1750mAh) to slightly bigger one (2000mAh).
Once I tried to fully charge it, it got stuck at 90% and charging process turned off, like the battery was fully charged.
Is there anything I shall do? Like calibration (if so - how to do it?) Or is it the battery that is being screwed and I shall get it replaced.
New battery is not original Samsung battery. It says to be Li-ion battery.

Try to completely drain the new battery and then charge it, without unplugging it, to 100%.
Break me off a piece of that Kit-Kat ROM!

Tried that solution, drained it down to 4% and then tried to fully charge. With no success, stuck on 89%.
I will call on for battery replacement.
And hey, grab that piece

Maybe discharge it to 0% till it shuts off and then charge it. If that doesnt work try clearing batterystats (sdmaid has that option for example).
Sent from my Galaxy Nexus using XDA Premium HD app

try to power off your device and remove the battery, for 3 mins or more then insert back and connect your charger untill its fully charged

Since its li.ion battery it shall not be fully discharged, may and probably would battery.
Waiting for new battery, probably will get it tomorrow and then will flash new snapshot of cm11 with full data reset. Hoping for positive results

Change thread name as I guess it is no longer battery calibration thing.
Got another battery and problem persists.
Let me describe the whole story from the beginning.
With my maguro, about 4 months ago, on original battery I noticed worse battery performance. It was getting worse and worse but fairly slow. After about 2,5 months (6 weeks back from now) my phone stopped charging up to 100%. The highest value it would get was 94% and then it would turn off charging. I thought that my battery is dying. After another 3 weeks it would charge up only till 90% and then stop charging. I decided that its about right time to change the battery.
Found substitute with 2000mAh. And the rest of the story is above. It would not charge till 100% (would charge only up till 90%), so I thought that the battery is dodgy. Got a replacement. With new replacement of battery I decided also to do clean flash of new 20140107 CM11 nightly. After clean flash I still get the same problem - my phone does not charge up to 100%.
Checked under *#*#4636#*#*: it says it is Li-ion battery, so in line with what it says on the new battery package (at first I thought they might be selling old types of batteries [ni-cd or ni-mh] under Li-ion labels).
Do you have any idea what to do?
Please be aware that I have already tried:
- draining and then fully charging;
- charging phone with phone switched off;
- gave a phone few minutes with battery out so it could somehow "forget the past";
- different chargers (dc charger, usb charger, car charger);
- resetting battery stats
Anybody any help? Solutions? Same problems in the past?

Battery discharging abnormally fast.

A few weeks ago i had this weird abnormally fast discharge got the phone at 2% battery for like 30 minites, then 3% battery. So i took this capture.

My phone is 100% stock 6.0, logd dissabled since months ago, same usage, very weird, so much frustation. From 20% to 2% in 20 minutes, wtf? .
Phone is 5 months old. H815P.
Help? Any tip, anything?
Sent from my LG-H815 using XDA-Developers mobile app

It's happening more or less the same on my H815. I've tried everything so far: plane mode or not, different roms stock or not, 5.1 and 6.0, dozens of factory resets, even a brand new battery, it's exactly the same everywhere. Phone will suck around 10% per hour even when freshly formated and untouched, even on plane mode. And any application informing of battery stats won't point at anything as the culprit, it's like the battery capacity is suddenly a 10% of what it should be but will still take 1:30h to fully charge. I haven't RMA'd it yet because mine has the bootloader unlocked but I might if it doesn't fix itself soon. What serial is yours? Mine is a 508.
Hopefully, living in Europe means they won't reject the warranty for an unlocked bootloader as it's obviously a hardware problem.

Been there, done that. No matter if I'm using a freshly factory reset stock ROM with all radios activated or a fully modded, debloated, greenefied and amplified CM installation on plane mode. Battery will still deplete at 10% hour with no culprit in battery stats (top one will be Screen with something like 30 minutes on and 100mAh used)

Thanks, I'll try. Even though Better Battery Stats does more or less the same and showed absolutely nothing (wakelocks et all) draining the battery.

That tool has a lot more granularity maybe it might reveal some more clues. Same goes for the OP.
let us know how it goes.

CM you get what you get...try Genisys

Does the phone get warm while this is happening?
the way I see it, you either 1) have crappy battery, and phone is normal so doesn't suck down lots of electricity and doesn't get warm, or 2) have fine battery, and phone is acting weird and sucking down all your energy.
If you are situation 2), then you would feel the phone get very warm to use that much energy so fast. If your phone is cool during all this time, then it's not using much energy to be able to stay cool, so you know your battery is having a problem.
maybe try cutting a hole in your pocket and put your phone against your thigh to really feel whether it's too warm.

15% battery and phone is "dead"

Hi guys,
I have a problem with... When battery drops down to 15, my phone turns off, and 46 six aps are being optimized. I'm not alone with this problem, my friend with HTC... has the same. Any solutions?
And now "com.google.process.gapps has been stopped and i must do hard reset.
Help guys.

I have the same problem, and im on a custom ROM! So annoying

Yea me too. I guess it's my fault or something like this. Sometimes phone can handle 4%, sometimes it'll dead at 11% and so on.

The battery meter isn't that accurate, its just an estimation based on the battery voltage versus how you use your phone (and the resulting "typical" battery drain). You shouldn't expect it to be accurate to the being within the 1-2 (or even 5) percent range. Shutting off at 4 to 11% is not unusual, and not surprising.
You shouldn't be draining your battery down that low on a regular basis. Its bad for long term battery life. Good rule of thumb for Li ion batteries is short and frequent charge cycles.
However, optimizing apps and/or google process stopped after a shutdown (due to low battery) is not normal. That's a different matter.

I have this problem, plus some of my settings get reset such as my wallpaper, ringtone, notification tone, boomsound (off to on), screen timeout, screen brightness, whatsapp (keeps asking me to chose my backup options and no messages come through until then). This has never happened before and I'm not sure why it's only happening now. I'm not purposely trying to drain the battery or anything, it's just that sometimes on the road I am unable to charge it and it'll just die out midway when previously, that extra 15% could've lasted me for another 30 minutes, just enough for me to reach my destination.

The same problem.. But the bigger problem for me, it's reseting my settings..

It is a terrible problem , I return to KitKat and my battery reaches 1% , and so normal ... I'll make a test with lollipop .

Yes, same problem! So glad someone made a thread for it. It's frustrating and happens literally every time.
Experienced on both the stock and a custom rom. Any one knows any fixes? Is it because of the 'battery life reduces over time' thing? My phone is 2 years old now

That seems to be a problem with all htc ones (m7, m8, m9) as they get older, dont worry its normal :laugh:

ive been experiencing this for a while, clear dalvik cache and let android do the whole rebuilding thing at the start and you should be fine...as for the battery fix ive just learnt to live with it, 15% is the new 2%!!!

I'm on this problem since a lot of time, as i was one of the first in the community to report it.
Seems like an end-of-life issue for one m8 and htc one phones line.
In my case i had a camera and charge board issue too, so in rma htc changed them, and now the phone is charging and quick-charging like it must have to. But i have to be careful when near 15% of battery because using camera, flashlight or others power-expensive features instantly turns the phone off, causing a database mismatch on the next boot (for marshmallow) and consequently the loss of data.
If the instant-poweroff occurs during boot, there is a massive loss of data and a lot of force closes on the next boot.
Nothing to do here i think, sadly.

In kitkat and lollipop battery reach at 1% ...

I have a fix for this as it happened to me and I tried a battery calibration app from the app store... I thought what your thinking now but after finding bad sectors and "repairing" it did actually work

solve the problem of battery and loss of settings , change the battery of my htc, now everything is fine , 3 days that the battery is discharged properly , I hope this information will help someone.

thats kinda "cool" to see many people have same problem as i do. atleast it wont run u crazy as before
1. sometimes phone dies when battery is 15%, and sometimes it dies when around 4% 2% or even 1%
2.resetting settings after phone dies!
so is the solution, to change battery? any better way that doesnt need to spend money?

Replace battery

Yes I've done this a couple of weeks back. The replacement is actually less hard as it seems.
But finding an original replacement battery seems to be pretty hard - Even though the replacement I bought is HTC branded and looks genuine, I feel like it's actually draining a little faster than my old original. 12€ Ebay had too good to be true.
However the instant-shutoffs are now a thing of the past along with the database corruption, so I'm going to have to live with a little less battery life.
Or does anyone know of a provider for genuine batteries?
