My new battery dies when it has 5% left i have been reading to calibrate it. What way should I calibrate the battery software or clockwork mod???? Thanks in advance i am rooted and am using AndroidRevolutionHD. I have used the battery calibration from the market but it seems like my battery is draining in 2% intervals. Is there any other software I could use or can what is your alls recommendation

Calibrate it the old way. Let it completely die and then let it charge for 8-10 hours. Make sure the phone is off while charging. Do that twice and that should calibrate battery. Also look on the market for a battery widget that way you can find out what is draining your battery.

i made this post because people might be wondering about how to charge their phones.
(i say these things from experience so if different for anyone then let me know)
make it a habit not to charger until its at least 15% or less. i always charged my g1 and left it plugged in even at 100 and after weeks the battery life went to hell. i went through 3 batteries that way.
Also try not to use the phone while its charging. i cant really explain what the hell causes that but i know from experience of two other phones that the phone overheats and messes up the battery. so that means avoid over-night charging. i charge mine either before i go to sleep of first thing when i wake up.
also when ur charging ur phone, DO NOT put it under anything, like between a pillow the bed. ur phone will overheat like to the point of too hot to touch. also from experience.
Thanks man,that why my old battery started die'n so fast

I normally do this to calibrate battery:
1. Charge to 100 % with phone on
2. Unplug and turn off
3. Charge to 100% when off (i normally leave it for 10-15 minutes)
4. Then unplug, turn it on, then after fully booted turn it back off
5. put it back on charger till it fully charges again
6. boot into recovery and wipe battery stats
now use your phone as normally and give it 3-4 full charge cycles till the battery is properly calibrated.
Battery calibration is a app on the market. Check it out! It saves you from having to go into recovery and wiping battery stats

i follow all of this and i usually get around 20 hours of battery life. and ive only calibrated my battery once.
So I was charging my Sensation and 4 hours later it was on 72% and noticed in the battery log the line was starting to dip. So I then took the battery out of the phone and put it back in only to find its now fully charged.
Defective battery or is my phone reading the battery stats wrong?
Battery life has been lasting 8 hours with normal use which is terrible.
Any ideas?
Thanks

Okay so I'm using current widget and let it charge past 100% until the widget displays 0mA. I calibrate the battery after every charge with battery calibrator. My question is will I always have to "overcharge" my battery to reach full 100% ? Or is there a way to permanently calibrate the battery?

If you're not flashing a new rom daily, one calibration should be all you need.
It doesn't work correctly I guess. My phone tells me 100%, but current widget says I have more charging to do. The only difference I see from calibrating is that the battery usage stats are erased and reset. It doesn't actually calibrate the battery. Is this normal, or am I doing something wrong?

If you wipe stats one time @ full charge, then use the device normally and charge when needed, the OS learns the usage patterns to correctly display percentage of battery left.
I wouldn't be so concerned w/what Current Widget says unless you're getting massive drain when the screen is off and the phone should be in a deep sleep.
Ok thanks. I won't rely so heavily on current widget then.

I'm reading some guides and posts about battery calibration...
I'm trying to do it with battery calibration apk, but I can't understand when battery is really full even if I use current widget (it stucks at 10mv, it does not come down to 0).
how do you calibrate?
Do wipe status as long as u riched this value as a maximum. .. restart. .. let it with out charging till it gets to 1% then charge it again till 100% do that a couple of times ur battery should be calibrated for good; )

To know when its fully charged you need to be watching ma not mv. As ma is the flow of electricity that your battery is currently receiving, as long as your phone is on it will not hit 0 as your phone will still be consuming battery so it will always sit between 10 and 20ma when fully charged. As long as your happy its sat around that mark for a few minutes then its charged. But best way to calibrate in my opinion, is to just discharge to 5% and charge overnight. Wiping battery stats does nothing as your phone creates a new battery stats file on its own after every full charge and battery stats.bin only contains information of what's been using your battery like in the settings menu. This has been confirmed on xda portal by a Google software engineer.
Your phone is clever enough to figure out what charge your battery has by measuring amps and volts once its been discharged and charged a couple times as by then it will have a established the minimum and maximum mv your battery can hold and battery stats file does not hold this information.

My battery is draining 890ma~1000ma when screen on.. even the charger cannot keep up
Now as i type, battery dropping.2% every 1min or so. Just 30mins use, battery is already at 48% .
But if screen off, the drain is like 2ma. I cant brain whats up with my phone
The battery itself could be going bad.
What do the battery stats show as the biggest user? And is there a wake lock that's keeping the phone on and spun up at full speed at all times?
Try using 'Badass Battery monitor' from the market. It would point to battery eating evilness.
