so i had the mytouch 4g for 3 weeks now 2nd week i calibrated which it fully died charged it fully to 100% with phone on. removed charger and powered off. charged to green light. took off and powered on. then turned off again and charged when off once agian to green. saying this would make batteyr better. i did the same today a week later i noticed battery has gotten way better over time na happyer with it but will this method mess up or effect anything since i did it twice?
You should be fine. Just don't do it so often. There shouldn't be that much of a need for it. Also, if you had ur mt4g for such a short time, the battery should be new, assuming you bought a new one. And one more thing,
Do not discharge your battery all the way. When you calibrate, wait till 1%, not 0%/Dead.
Here are proper ways of doing it. Pick one that you like/works for you.
Method 1: Brought to you by ckisgen
1. discharge it down to 1%
2. turn the power off and plug it into the wall charger
3. charge it for at least 6-8 hours (the more the better)
4. power on by booting into recovery (leave it plugged in)
.5 wipe battery stats (under advanced)
.6 boot it up and let it charge while turn ON for another 30-60 minutes
7. make sure you fully discharge it again down to 1%
8. plug it in and let it fully recharge again (ideally another 6-8+ hours and ideally powered off again)
Method 2 (this is if you must calibrate but do not have the time to do everything) brought to you by coltfoet5
I calibrate by..
1. Charge to 100%
2. Boot into recovery/advanced/wipe battery stats
3. Reboot system
4. Run battery down to 1% then charge back up to 100% constant
Method 3 brought to you by altroy2:
1. Download Battery Calibration by NeMa from the Market
2. Run your battery down to 1% but not to 0%
3. Plug in your charger
4. Run the Battery Calibration app
5. Once it beeps = Full, click Calibrate

So I followed the calibration method outlined by Sprint/HTC and wow oh wow, completely night and day.
Before the calibration, I let the phone charged over night and unplugged it to go to work. Within first 2 minutes, it dropped about 4% which is crazy. The rest of the day is gradually fading and I get about 16 or so hours with very light usage.
Fast forward! Did the calibration by plug unplug, plug unplug for like 15 times while watching football. After the calibration, I pulled the plug and it's been almost 3 hours with only 1% gone. This is just crazy if you ask me by just a simple technique.
I'll let it go unplug to see how far I can get. Oh on top of this, I use setCPU to scale and JuiceDefender as well. Same settings before calibration.

If I'm not mistaken its this:
To also help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour
Please tell me if this is not what you were talking about.
I tried both methods and the only way it worked was if I did it every time I charged the phone.
Link to method? I want to try it out.

Crap, I forgot where I saw it but I remembered it for the most part.
Charge your phone fully to 100%.
Once done, turn on the phone, the light should be green. Unplug it and wait until green led goes off. Now plug the phone back in and wait until green led goes ON (it will almost be immediate). Now turn the phone off and unplug the from charger, wait for led to go off, now plug the charge back and wait for the led to go ON (Note: if you are using CM6, I think the screen will turn on automatically when phone is plugged in. If so turn the phone/screen off). Now unplug and repeat this step for about 10-15 times.
After this, unplug your phone and let it sit and you'll notice the difference.
The method above is not what op was talking about. HTC method is above somewhere.
Charge with phone on for 8 hrs.
After charge with phone off for 1 hr
Then charge again with phone for 1hr on (not sure on this step).
That's the HTC method they claim worked a whole lot for them....
http://forum.xda-developers.com/showthread.php?t=712990
That's the way to calibrate it...
The post above yours IS from the OP. That said, he may not have been talking about the official HTC method. Either way, I have tried every method on the forum and all work... for a couple of days. I havent seem one yet that will keep the battery calibrated for a substantial amount of time.
the reason the unplug plug in unplug plug in method doesnt work all the time is basically you are over charging your battery. I dont recommend it personally. I would follow the HTC method. takes longer but less dmg to the life of your battery. I ussually do it about once a month and it holds pretty true.
My solution is to charge the batteries in an external charger. Every morning I out in a afresh battery and its great. Its only the phone that can lose the first 10%.
I don't charge the phone directly anymore.
Sent from HTC Evo.
I just did the "official" HTC method. Well see how it goes....
Or, you could see that the phone has a serious bug and does not trickle charge after it hits 100% and does not start recharging until the phone drops below 90%. So, when you take it off the charger in the morning it will have somewhere between a 90% an 100% charge. This is why, when you unplug it, your phone quickly drops to around 90% and the behaves normally.
You can easily fix this by unplugging your phone for several minutes (5-10) and then plugging it back in to get it back to full charge. You will notice that your battery % doesn't drop nearly as fast and it lasts several hours longer. Or, as was said above, you can charge your battery in an external charger (these don't have HTC's bug).
I get 6-7 hours of solid use (screen on, surfing the web, listening to music, watching videos, texting, emailing, and and making calls). Oh, and I use 4G often and still get 4-5 hours.
Anyhow, that's much simpler than all those steps IMO.
I have HD2 with
1- windows mobile 6.5
2- ROM Prestige X
3- Radio 2.15.50.14
4- Android ROM Moto234_Incredible_Remix_V2.0
When I want to charge my device it is stop at 91% even in the charge plugin more 5 hours, so any body faced this, and what do you think the problem.
The same Scenario was happening to my hd2, it stopped at 91%, even i let it charge for long hours, it does not pass 91%. This is what i did, I let the phone charged on the Winmo side, till it gets full charge 100%, then i return to the Android side while it still 100%, used the phone and when the batterry need to be charge, i let it stayed on the android side and charge it there. Since then about 2 weeks now, it will charge now all the way to 100% on the Android side. I only return to the Winmo side 1 time to let it charge 100%, and never return again since then. This is just my experience, let me know if it works for you. hopefully it will.
I've also noticed that if you let your battery drain down yo almost empty it will charge to 100% consistently. If you always keep it on a charger and never gets very low, you will start to see its Max % get lower. I don't know if anyone else has noticed this. Just my .02

Boot into WinMo, charge phone until 100%. Turn phone off and let charge for another 15 minutes. Boot back into Android. Open terminal emulator and enter:
su
rm /data/system/batterystats.bin
Unplug charger, and use phone until it powers itself down because of empty battery.
Your battery is now recalibrated. This has also been discussed quite often already.
well... here's an easy method;
plug your phone in with the charger
charge your phone until it wont go anymore (in your case 91%)
open up the back, and pull the battery when the phone is on
put the battery back in and reboot into android (while still plugged in with the charger)
Once it's booted up to android unplug the charger and replug it back in.
it will go to 100% from now on.

weird i've done this with the same SD card for pretty much every single build i've tried, and have not had any issues with the SDcard being corrupt.
with every new build however i wipe the SDCARD and reformat it...
that may be why... who knows?
% doesnt matter ... its cuz u dont have it configured to ur battery and most likely use an other one too ... but if u keep swapping it will never configure ..
as i said the % doesnt matter , as long as its 4.195v+ its full !
so last night i pluged my phone in before i went to bed and when i took it off it was on 77 % well ive tryed charging it today some and now it wont go past 80 for some reason. ive tryed to wipe the battery stats and stuff but no help. Im on aura #8 debloat rom and its worked fine for the past 2 weeks and now its starting to act up any help will be appreciated.
Try a full calibration, not just deleting batstats. Run the battery completely out, charge while off (hopefully) to 100% then power on make sure its 100 or charge to it, then delete batstats and let die again.
How are you charging it?
I have a similar problem when I use a usb port on my pc.
See the battery callibrating thread a few threads down.
Speedily sent from CM7 Beta
Charge to max while phone is on, delete battery stats with battery calibration. Then take out battery and plug your phone up to a wall charger then put your battery back into the phone and let it charge.

Hi, I have flashed my phone into the Nighty CM7, I finished setting up and restoring my apps, then I wanted to boot into ClockWork Recovery so that I can backup my rom.
However I ended up with a dead reboot, its stuck at the M Logo. I waited till my battery died. I charged the phone for a night, and I ended up with the big battery sign with a QUESTION mark in it, the light beside the USB Port wont let up.
I connect it to my computer using the USB Cable, the Light beside the port lit up, but it wont charge nor boot, I tried to put my phone into RSD Mode so that I can flash my stock rom again, however it says "Battery Low Cannot Programm" and turns back off. I cannot put it into Recovery Mode by holding x and the power button.
CAN SOMEONE HELP ME? I CANT USE MY PHONE?

Ok, to be honest, this was stupid. Your first step is now get battery charged.
You have following options:
charge it in alive Milestone 2
charge it in some universal battery charger
charge it via wires (yes, it sounds risky and definitely it is not too good for battery life, but someone here successfully done it) - manual attach wires with coresponding voltage and give it few minutes - only to hold charge few minutes for RSDLite... Or you can maybe bypass battery and put wires directly on phone - but this is really risky and I dont recommend it.
Of course - best option is #1 or #2... But you can't do anything without charged battery...

it doesnt work when the battry is charged charged, thats why i waited till the battery to die untill i start over again. I have looked online and dont think this is really a battery problem~
Look at here http://forum.xda-developers.com/showthread.php?p=19197228 - I think it's the same situation. You have to charge the battery to use RSDLite.
tl;dr Low battery = "Battery Low Cannot Program", charged battery = "Battery OK / OK to program" in RSDLite.. so...
sorry, how am i suppose to charge it? it wont charge, so i need a battery charger instead of charging it through the phone?
Yep, you can't charge your battery (in your phone) when you have bricked phone (thats why I said it wasn't good to let it die, because now you have one more problem - how to charge this battery)
And I wrote how to charge it in my post #1 - basically you have two options: universal battery charger (charger, where you put battery and it will charge it) or another (working/alive) Milestone 2...
great i got another ms2's battery to boot into recovery mode (rsd mode works too) thanks, i am a noob
No problem man, everyone makes mistakes time to time
It's good to see it solved and alive
well its still sbf-ing, one thing i notice is that its taking longer than usual, but i think it will work, thanks again
Your lucky then! I don't know anyone with an ms2 so had to go macgiver style and charge the battery directly with wires. I swear the battery has never been the same since, although every battery/system tool claims the battery health to be "good"

If you're refering to me - I've done that already and no luck
I've tried every trick on battery calibration I've found on this site and google searches and it never shows any noticable improvement.
So now I'm just more vigilant with battery saving tricks
Thanks for trying to help either way

I have a similar problem
My battery was getting bad for a while, so I bought a new one off Amazon USA (I hope it's real). However since I put the new battery in my phone and switched to CyanMobile, my battery has been all over the place.
I can't get through a 9 hour work shift on 2G speeds (where I may glance at my phone 2 or 3 times). As well as the battery running down quickly, it'll jump from say 80% to 60% or 50% to 30%.
It does this both when charging and discharging. i.e. the phone just died. I plug it in to charge whilst switched off, and the screen immediately shows 20% charge. I turn it on whilst plugged in, and by the time it boots up it shows 60%!
I've tried deleting battery stats in recovery mode, and using a battery calibration app from the market...but nothing
What to do?
