[How To] Calibrate a Battery - Hero CDMA Q&A, Help & Troubleshooting

I get asked all the time the proper way to calibrate a battery; so, here's a proper guide for you guys to use to do so and save some post space
How to: Calibrate a Battery correctly on the CDMA Hero.
Charge the phone to 100%
Boot the phone into recovery.
Wipe battery stats
Power phone on, and unplug your fully charged phone
Use your phone until the battery dies. Completly. You want to use it until the phone automaticaly powers off due to low battery
Recharge phone
Repeat the Charging/Killing proccess about 2-3 times
Your battery is callibrated!
Hope this helps cut some questions down!!!

Lol, thanks man I get asked this so much, I figured, why not?

Afraid to let my phone die completely like that. 3x I've had my sdcard need a reformat after the battery died. Only have let the battery die about 5x.

Really?
I recalibrate after every new rom or update to base rom.
Not needed, but I'm weird.
Never hurt my sdcard. Had this phone over a year and a half now.

I love it and think it's better Faster, better screen, keyboard

I've got a transcend 8g class 6 right now and it got messed up just this weekend letting the battery die. It did it the other 2 times on an old card then eventually went tits up not long after that. Needles to say 3 of 5 isn't a good ratio so I'll not be letting the batt die on my phone any time soon.

That's odd... never had that issue with sandisk

I've actually had this problem with 2 8gb class 4 sandisk both died on me, one frozen... not sure if it was related to letting the phone die...

Thats odd.....

you can always unmount the SD card when the batt gets low, so it would be harder for it to mess up

As many times as I've done this procedure, it's never helped in the least

Bummer.
I ALWAYS get 26-30 hours battery life. I would say medium use.
Maybe an hour talk time, lots of data, sms, mms.

The battery isn't that bad as you think.

I think I did good today with slightly heavy use.
I will say that I don't consistently get this performance but when I do I don't complain.
Also juice defender seriously makes a big improvement.

This screenshot essentially shows us nothing without the other two. You need to click display in order for us to see the screen on time and click where it says 23hrs 15min as well. We need all that.
The only thing you've shown us is that the phone made it 23 hours and that you actually charged it for a little bit as well LMAO

lol, I bet he didnt think you'd see that :laugh:
ok so i came to the atrix at a what i have to say is a perfect time. i bought the phone and 2 days later there was root! i mean i was pretty lucky, had to wait for the unlock code and suffer one day without root! not to shabby. now while i had minimal time without root my battery seemed fine. however, i have since installed setcpu after root and dropped the clock down to 384mhz. while i know its slow! it still gets the job done. have a look at the screen shots.
Any random reboots??

if your asking me which i think you are...none at all. i mean dont get me wrong it takes an extra second in response to what you want to do. its by no means fast at that speed but i ended up getting nearly 21 hours outta it. the battery died while i was playing a game lol. i was hoping to beat it into submission that way. took less than 3 hrs to fully charge back up as well...
You guys need to show your screen on time. Without that, the numbers are pretty meaningless.

From the battery screen, touch the screen entry. It will show the screen on time. Without that, there are too many variables.
Like this...

Hardware or software issue?

I've had the Note since February and its rooted but running stock. A couple days ago I took the phone off the charger and the notification of the battery saying it was charges was still showing. I have tried taking out the battery and rebooting but it's still there. Ever sense then my battery life hasn't been the greatest.I haven't tried a master reset though or getting a new battery. Any ideas what it could be? If this is the wrong section mods please move it. Thanks.

Sorry but it sounds to me like you need a new battery... You may even run the risk of damaging your phone, if you keep using the same battery...
Ps. thats a gut feeling only... I am not a engineer

Clean your usb port with some alcohol, take out your battrey for 5 minutes, insert your battrey and your note is good to go..Ifproblem comes back again try changing your charger

Or probably try to wipe battery stats in the cwm recovery.

typical symptom of a infected USB port. clean it as rishab_s said. use lil alcohol , cloth and toothpik.. it should be fine after a few wipes.. unless the pins are physically damaged

Alright I will try and clean it this afternoon. I sure hope its something small. I'm fine buying another battery if its that also. So some people have had this happen before? Could it be because I'm using a converter for the wall plug in?

That's an idea, well the phone no longer is showing the 100% charged indicator. The phone was completely dead and its now showing 50% charged. I am using a new charger now. Do you think it could be the battery?
Sent from my Factory Unlocked iPhone 4 using Tapatalk
so when u plug in the charger its showing charging and when u remove the charger?
It stops charging which is a good sign, I hope! But it stays at 50% so was it really dead to begin with?
Sent from my Factory Unlocked iPhone 4 using Tapatalk
Use the phone till it goes till 5 %and then change again.
So don't charge up to 100% then drain?
Sent from my Factory Unlocked iPhone 4 using Tapatalk
no for now.. drain and charge again
Alright I will do that. What if it dies or the battery decreases in an hour or so like its been doing? Is it the battery then?
Sent from my Factory Unlocked iPhone 4 using Tapatalk
u will be using it for a while right.. keep a watch on the battery... if its reducing too rapidly.. then u will come to know..

Battery life probblem

Hey guys I just got a miui ROM running on my ace and the battery goes from full to empty in about a hour and half is there a fix anywhere for this I did have a look just I didn't see it buts that's not to say I didn't miss it. Would be grate full of any help
Sent from my GT-S5830 using xda premium
This problem could be could be due to the rom that you are using, although it seems strange for it to be that bad.
One thing you could try is underclocking to save power, it wont make too much difference but it is a start.
A second solution is to simply buy a new battery as your current one may just be old.
there is also the obvious basics: low screen brightness, stopping any unwanted services and try to steer away from live wallpapers
hope this helps.
You should test another rom
Change your ROM brother !
I've tryed a few rom's since I posted this battery must be done in. It fully charges in less than 10 mins and runs out in just over an hour fed up charging my phone lol

yes, its probably best to get a new on then, be careful though a lot of the ones on sale are fake so make sure that you find a real one.

[Q] Without a removable battery how do you force reboot?

My upgrade is due on May 1 and the One is in my plans.
I have never had a phone that didn't occasionally need the battery pulled. How does it work work with current phones?

you just have to hold down the power button and it will reboot
This why I don't understand why people cry over pulling a battery. It's more simpler.

You're right though, the "work" involved is just exhausting

True true, but it is less obvious to the uninformed I guess.
Not many people would just think to hold a button for 10+ seconds, some people I talk to don't even have the idea of "long-press" down pat (which I bet is why HTC has largely removed this from all but a few places on the phone)...
.... But you have people as old as my grandfather that know all about yanking batteries out of crap when they ain't working!

****, I charged my HTC ONE for 16 hours.

Oh god, oh god.
I just bought it yesterday and I'm really scaring of holding it.
It sat on a pillow, in a box [so it would'nt collect dust] the whole night, connected to the charger ofcourse [as I had around 87 Percent at the end of the day I decided to charge it]
This morning I woke up and had to go straight to work, ofcourse I won't bring my lovely new HTC ONE to work, so I left it there and forgot it was charging.
****. ?
Did I harm the battery? it sat there charging for 16 hours. since 0:00 - 16:30.
Please tell me it's alright and doesn't harm anything at all?
Lol. You're overreacting. Absolutely nothing will happen unless you do this every day for months in a row. And not even then maybe.

Thanks, I started using it more seriously today, battery's down 26% since I unplugged it.
It went through almost constant use (opening instagram, opening settings, just watching the homescreen)
It's been around an hour of this use with the phone on saving mode and airplane mode with WiFi.. is it okay?
