Okay, so my HTC One X wont charge to full, no matter what. Heres what I've tried so far...
- Wiped Battery Stats from recovery, then tried charging.
- Turned off the phone and left on wall charge for over 6 hours but still was less then 10% charged, then wiped the battery stats from recovery, and it gained 40% charge.
- When I wipe battery stats, phone does gains about 20% to 30% charge, but then starts to drain even when on charge saying "Your phone is using more power then supplied, close apps or turn off the phone."
- Once calibrated it when the charge was half, that was the only time it showed me 100% charged, but then again same problem.
Phone is rooted and running JB stock.
Any help would be appreciated....
batterystats.bin has absolutely zilch to do with this. It only logs things like 'x app ran for y ms' and does not affect the battery charge shown in any way.
Anyway, did you try charging with a different charger? Does charging from your computer change anything?
Yes, tried charging using my laptop, but still the same.

Does anyone have a link for the thread that discussed the correct way to wipe battery stats when upgrading to a new Rom? I remember it went something like drain dead, charge to full, drain dead again then charge to full and wipe stats. I can't remember the complete process. Thanks for the help.

I've seen a couple different threads on that here, one saying discharge fully then charge while powered off, and the other saying to do a full charge "conditioning cycle". I did the latter and it seems to have made a difference.
Here's what I did:
Charge the phone fully with it powered on
When fully charged, disconnect cable
After green LED goes off, power the phone off
When phone is fully powered off, reconnect cable, amber charging light should be on
When LED goes green, disconnect cable
Repeat previous two steps 10 times
After 10th cycle, boot into recovery and wipe battery stats.
I am using Amon Ra recovery which has the wipe battery stats option under the Wipe option. I never did this when I had Clockwork recovery installed, so I don't know if the option is in the same place.
Being an electrical engineer, I find this business of battery conditioning interesting, along with the Ni-Cd "memory" vs. Li-Ion "no memory" issue. If anyone has found a decent physics-based explanation as to why these things do or do not have any basis in fact, I'd appreciate a link. Yes, I'm too lazy to Google it at the moment.
Hmm, I may have to look into this again. I charged my phone all night (powered off) and unplugged it this morning. I did nothing with it this morning but turn it on and look at it, then put it in standby (quick press of power button). It lost 16% of charge in less than 2 hours!
I'm running BS1.2 with the Baked1 (low voltage/best battery) kernel.
Damn, just installed System Panel and found that my CPU is at 100% constantly!
I'm trying this now. The longest I've pushed my battery was 22 hours... and that was with 39 minutes of screen on time, lol. In standby almost the entire 22 hours....
Ok, I believe my issue was related to a camcorder problem, my CPU usage has dropped back to normal levels after fixing that separate problem. After my battery recharges fully I will see what happens with the charge.
the other methods to do "calibrate your battery" (which isnt really calibrating the battery but the battery stats of the phone so it can accuratly judge when it stops and starts charging)
1) charge the phone to full
2) unplug and use phone till it shuts off from no battery (do not plug in until it shuts off)
3) charge phone to full again with out unplugging till 100% (check under about phone > battery it shoudl say full charge there)
this should reset the battery stats.
the last method is one from HTC
1)Charge the phone for 8 hours uninterupted with power on
2) turn off the phone and charge for an additional hour
3) turn ont he phone unplug it and let it sit for 2 minutes then plug it in for an additional hour.
all 3 methods listed should help. I personally dont like the x10 method because it has the potential and basically over charges the battery to make sure it is acctually at a full charge. It is much faster then the other 2 methods though so to each there own.
Dont waste your time on...
plug/unplug 10 times. It really doesn't recal the battery.
the unplug/plug 10 times.
1. Phone on...charge until green light comes on. Immediately unplug and turn phone off.
2. Plug phone back in until green light comes on again. Immediately boot into Recovery and wipe battery stats.
3. Use the phone on battery until dies.
4. recharge phone to 100%
You are good to go!
If I tether during the day (5+ hours) a lot, is it bad on my battery? Isn't that like a constant charge or does once the LED turn green it stops trying to charge?
Thanks.

the evo doesnt do a trickle charge so when the light turns green it stops, this is why you will almost always drop 1-5% battery rather quickly.
Are you sure? My light has been green for a while, and my phone battery status says 'Full'.

There's a lot of confusion over how the battery / charging circuit works and how it reports. My advice is to just charge until it's green and full, then unplug it. If you leave it plugged in all night, unplug it for 10 mins in the morning, then plug it back in to top off.
That doesn't really help me SilverZero, my question is only if leaving it tethered (which means connected to USB) is bad for my battery.
Well on mine i would check it every once in awhile and i would see that once it get downs to under 90% that it would charge again till it recognized that it was full again. So based on that i dont think you should have to worry about it. It seems to only draw the charge when needed. I also leave mine plugged in alot when im home so its good to go when i leave and havent noticed a loss of battery life at all.
You guys don't want the charger to trickle charge. Li-Ion does not accept overcharge, even 0.01C (15 mA on the stock Evo battery) will cause it to vent and probably combust.
So does "calibrating the battery" calibrate the phone or the actual battery?
I ask because I have 3 spare batteries, wondering if I have to do this for each of them??? They are all standard size, one of them OEM
So, I'm on my Evo today, playing a game (Air Strike). My battery is at 93% when I picked the phone up to play, and the phone is plugged in. Suddenly, with no warning what-so-ever, my phone shuts off. Of course a mini-freak out and many "wtf's" ensue. No warning, no signs, even the led went off. I pulled the battery, put it back, then plugged the phone in again. After that it gave me the blinking light indicating the battery was too low to turn on. After a few minutes charging she came back on and battery was at 5%.
How the hell does a battery go from 93% to 0% in less than 5 minutes, and give no warning at all?? Anybody else ever have this problem?
Wow I've have never heard or that happening before. Maybe a glitch in the battery stash? Did it take awhile to charge up to 100%? Can you reproduce the issue again?

I had this problem with my older phone once. The battery itself may have a problem or your phone is not getting charged properly.
Try These :
1) Try charging the phone overnite from the Wall charger (Not through USB of your computer)
2) If the above does not work, and you have access to another evo battery, then try using that.(try using a friends battery and charger for a day. ) (Ofcourse needless to say the charger and battery must be for Evoonly )
In my case, my phone started working fine again after getting my battery & charger replaced.
Probably shouldn't worry about it too much just yet. Could be something as simple as your battery meter was mis-calibrated. The meter itself is software so it can easily be wrong/off. If it continues you may have a bad battery.
Sounds to me like something is wrong. Did you just get the phone or have you had it?
Idk... The phone had been plugged in for most of the day (hadn't gone anywhere. Lazy day lol) And like I said, the led went completely out as well.
Haven't had the problem again, so we'll see I guess....

I've seen some posts about the Evo battery shutting off the charge when its being used. Were you using your Evo while it was charging?
If the battery doesn't seem to be giving you percentages that are accurate, you might want to recalibrate your battery.
Common misconceptions sticky (Evo Q&A) said:
Battery recalibration (Thanks to Cyanogen for this and to fachadick for bringing it to my attention).
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
2. Boot to recovery and wipe battery stats.
(To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for your ROM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue.)
3. Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off. Take out the battery, and keep trying to turn on your phone until it will not turn back on at all.
4. Recharge the phone completely and then use as you normally would.
This is a method that has been proven to work, I am sure there are other ways. My battery lasts longer after doing this and the reading is much more accurate. It might be advisable to do this after every ROM install if you want the most battery life and most accurate battery reading by the phone's software.

I just wiped battery stats. I let it drain fully, charged it fully. Unplugged for 5 secs and plugged back in light still charging for at least 30. I've on my third time. Just wondering if things are different with the incredible 2 battery. It didn't take this long with my eris. Basically, my phone has turned to fully charged within in 30 seconds or sooner. Wondering if i'm doing something wrong.

On the Inc1 I would do as follows...
- Charge phone fully with bump charge
- While phone was bump charged and charger still plugged in, boot into Recovery and wipe stats
- Reboot into ROM and unplug cable and use the phone until it was completely drained, not even able to boot.
- Plugged in charger and turned on phone.
Thats all you should need to do. To be honest I dont feel battery recalibration is important anymore because after constantly wiping stats I noticed that battery wear doubled. If you are changing from ROM to ROM then the stats should automatically wipe themselves over time.
Just my two cents and my battery life is fantastic - without wiping
Okay, i was wondering because i've flashed 5 roms in the last week. I wasn't haven't bad battery life, just thought i might need too. Thanks
Calibrating your battery doesn't improve battery in any way. It merely seeks to reset how the battery reports it's usage to the OS, since over time with normal charge/discharge cycles, the battery stats adapt to the user and reporting accuracy is degraded slightly. It's good to do on a periodic basis to correct this.
I had a show running on Netflix while working at my desk this morning, when my phone froze solid. No buttons, hardware or soft, would respond. The phone was connected to AC power and was showing 100% charged battery.
I pulled the battery, replaced it, and booted up. When it came up the battery was showing completely discharged (2%). I'm rooted w/ ClockworkMod installed, so I rebooted into recovery and cleared battery state/Dalvik/cache as a precaution, but this changed nothing.
So, now my phone is powered off and charging. The battery level is increasing (very) slowly, but has anyone seen this, or does anyone have any ideas what happened?
Charge it to 100%, then wipe battery stats from recovery, then drain battery completely (no "on the go" charging), then recharge to 100%.
Hi all,
My One X charges strangly I think. It charges really fast from about 80% give or take. It should charge slowly (given the nature of the battery). When it says the battery is charged, I unplug the device and within 15 minutes or so the battery is already at 90%. I have a feeling that the device somehow think the battery is fully charged while it is not really the case. Could this be resolved by doing a factory reset so that the battery stats will be removed? Or should I seek some other solution for it?
I'm currently on stock 1.28.xxx.x, the same problem occured at 1.26.xxx.x.
In the attachment I made a sketch of the behaviour of the charging
cheers
+1
Same here. Tried the factory reset after the 1.28 OTA, but am still getting the same pattern.

Someone said battery was improved after about 3weeks use. So 7days! For me left!

The green charging light goes on at ~95%. When the phone charges all the way to 100%, it disconnects itself from the charger until it goes back down to say, 95% again. When it hits 95% it will then charge itself back up to 100%, and this cycle will repeat. That's why sometimes when you pull the phone off the charger it is down to 90% or 95% or whatever sometimes within a few minutes.
