[Q]Battery Calibration

[rdmay20]

My htc amaze doesn't display battery % correctly all the time.
How can I calibrate my battery? I see a bunch of methods but Im not sure whats best for the amaze
Im useing bulletproof 2.1.0 and faux .008 beta 4
thanks!

what has worked for me with bulletproof is to drain the battery to under 15%, charge it overnight, boot into recovery and wipe the battery stats.

will try it, thanks

so i figured out that my phone doesn't read my battery life correctly anymore, it will be at 39% and shut down, then i turn on my phone it will have 4% and itll turn off right away so i plug in my charger and it'll have 55%
dont really understand whats going on any help?

I just used this app and it worked, it reads the percentage just fine

I havent been able to get my battery to stay at 100%, just says 99% and i have to guess when its fully charged. wiped battery stats and everything. running the same ROM

As the app says, all it does it delete the batterystats file. Use root explorer and go delete /data/system/batterystats.bin and you accomplished the same thing as that "app"

I get the same thing.. and because the device doesn't die all the way(at about 1% it does a soft power off) I can't get it calibrated right.
I'm using senseless, and I think it is more than the battery stats file.. tonight it was at 40%, started bootlooping for no apparent reason.. pulled the battery, rebooted and it said it was at 13%.
It has been a solid rom in a lot of senses(pun?), but I may try something else because of the quirks it has been having..

thats what was happening to me, i did a full wipe, using bulletproof, then calibrate, Im still testing but so far it reads fine, will update if everything is working fine in a couple of days.

another method is abit troublesome...
1. charge your phone battery till full (off mode)
2.when full unplug it, and open up the cover
3. take off the battery and left it there over 90sec or more..
4. put back the battery n bootup your phone.. it should calibrate..

if your battery is used too long it might your battery problem

I might try this. My battery indicator stays at 100% for like ten seconds or maybe longer then goes back down to 99%. Makes no sense lol

I'm only a two week owner of the Amaze, but I've found curious differences between the stock battery and the Anker (1900 mAh). First, the stock battery will remain at 100% for a fair length of time before starting to drop (sorry, I haven't quantified it, but it's easily half hour to 45 mins even after making a call or two). However, the Anker battery drops off of 100% pretty quickly, as little as 10 minutes without doing anything. Admittedly, I've cycled the stock battery a few more times than the Anker, and even Anker says it takes 4 to 5 full charge and discharges to reach best performance, but I don't recall the stock being that quick to drop even after the 1st full charge. I haven't used the Anker enough yet to have a feel of whether the Anker will last longer overall, though.

Off topic, but somewhat related - The Anker charger doesn't seem to charge the battery to a full 100% - either the Anker battery or the original. In both cases, as soon as I install the battery from the Anker charger, the Amaze meter indicates just 96%. I even left it plugged in for another hour after the light turned blue, but it didn't help. Not a biggie, just an observation.

BTW, I got this from someone else who had already posted it, but according to a Google Engineer it seems that resetting battery statistics doesn't help. Read about it here: http://www.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer

exactly lol. my battery will stay at 100% (99% according to bulletproof) for a long time then once it drops it drops fast

I left my phone off while charging, and I'm having good results.. only weird thing is that it slowly flashes on and off the orange light and never shows green while powered *off* and on the charger.. I can't find anything that shows this is normal. Is it supposed to get to a green light when powered off and charging?

Hmmm. I would check this out! http://www.androidcentral.com/wiping-battery-stats-doesnt-improve-battery-life-says-google-engineer

I didnt think it improved battery life, My phone just didn't read it correctly which wiping battery stats does fix!
