[Q] Battery percentage/calibration PROBLEM - Defy Q&A, Help & Troubleshooting

Hy Guys,
I have a problem with my Defy's battery (not exactly with it.)
If I fully charge it, it "drains the battery" fast and when it says 1% reaming, it lasts about half of the battery time.
So, I tried to use battery calibrators, delete the batterystats file, but nothing. My battery is new and as I said IT LASTS A LONG TIME? BUT WITH BAD PERCENTAGES.
Please help me, because it's so damn annoying

I think best combo is full discharge + full%charge (and 1-2 hours more connected after 100%) and then reboot in recovery to clean battery stats.
The battery need autocalibrate with full charging cycles.

please search Battery Calibration app on Play. Use it after dropping battery stats.

I got this screenshot of my battery drain. There are random drops and I didn't use my phone at that time.

Nexus One Battery Issue - Weird Problem

Hey I've been noticing a weird problem with my nexus one. I usually charge it over night so by the morning it's at 100%. I rarely let my phone die completely as I'm in and out of the house all the time. so i charge it when im home. however i noticed that when it does die completely, my battery level will say 30% 40% charged and then it'll suddenly die while im using it. i downloaded a battery widgit as well to make sure it wasnt just the system's battery charge indicator. the widget will also say the batter is charged 30% 40% and then the phone will suddenly die. When i plug the phone in and turn it on, then the battery level will say 1%. this has happened to me on both the stock nexus one and now im using the modaco sense rom, and same thing. any insight on my mystery?
Try going into recovery and wiping the battery stats.

After wiping battery stats, charge the phone completely while it is off until the light turns green (this will take a few hours). This may solve the problem. I had battery issues too, but after doing this, it fixed it. Good Luck
so i tried both suggestions; wiped the battery stats in the recovery. and charged phone to full. tried it out for 3 days. and no results. my battery level indicator is still inaccurate. any suggestions?

When you recalibrate your battery, it takes a few life cycles for the battery to stabilize and for Android to get an accurate reading. First life cycle is alway short. Of course, don't play with ROMs so much it may damage your phones read only memory.
I will post my battery life soon, I'm still waiting for the battery to deplete, I haven't recharged my phone in 4 days now after I calibrated my battery.

Wow 4days is huge,iam getting hardly 1day battery after calibrating yesterday....
Actually i removed my phone before getting the 100% notification....
So should i wait for battery to improve???
By the way,when did you calibrate???
Should i calibrate again????
If this wont work i will try terminal emulator method...
So in this method do we need to charge 100% or discharge completely??
Some precautions or just write those commands at any point of charge???
Iam wondering how to thank from the xda app
Thnx to both of u

Same problem here.
Battery drained from 100% to 60% in 3 hours, then to 15% after 5 hours. phone super hot! Widget showed temp 42°C !
Not even used the phone for more than 15 min! REALLY!
Then calibrated before 3 days, now a max of 1 day battery backup only.
Plz help.
And 1 life cycle means I must let the phone charge 100% then let it discharge till it's switched off.
And I should repeat the cycle.correct me if I am wrong.
And I have the habit of not charging to 100% in a single charge session, 2-3 breaks, should I change it?
clarkkov said:
If your phone is hot without you using it, something is running in the background, that shouldn't. Which ROM are you using and which tweaks/fixes have you applied?
One battery life cycle means battery drain from 100% (fully charged) to 1% (fully discharged). Your phone does not have to turn itself off, but make sure it is at 1% when you begin to charge it again. This is important only for a few cycles after calibration, afterwards you are free to charge it as you wish, but while calibrating it's highly recommended that you don't interrupt the charging process (4Hrs).

I am using rooted jpd from samfirmware, no fixes except sdcard speed fix, previously it used to give a good battery backup.
And apps do run in background.
Should I set autokill level to high in task killer?
And I will take care of charging.
Thanks for support.
on DDJP2.. getting a horrible backup since i have updated thru KIES. generally on jg6 used to get almost 1.5 days which has come down to 12-16 hours now. trying to calibrate my battery with app 'battery calibration'.. calibrated once.. but still no change. read somewhr that we get the same backup for first few times even after calibrating.. but to get sure i am writing down my process.. plz chk if m doing right or not ..
1. plug in phone with charger
2. wait till 100%.
3. press battery calibration or delete batterystat.bin with the help of root explorer.
4. unplug charger and use it till it discharges completely.
5. charge again to 100%.
plzzzz chk and tell.
plzz someone reply.
I have a question about batery drain. Apps on backgroung are drainning lot of batery? May i have to stop them always?

You need to be aware that wireless services are draining the battery the most. If you are not using 3G - switch it off, same with BT and WIFI. Widgets that update frequently also drain the battery fast, background data, auto sync services/features are battery killers, too.

Thanx for the reply.. i have calibrated once more.. but already showing 80% after hardly 2 hrs.. no clue whats going on... ppl with JP2 shud come up with thr battery backup to get confirmed.
and last thing am waiting for is that someone said .. battery life is worse for first few cycles after the calibration... thats the last hope... :'(

Simplest way to calibrate your Battery [for root users only]

I noticed that in CWM 3 (on gingerbread running device), when u click on wipe battery stats in CWM, Nothing happens while in old CWM's when we use to click on wipe battery stats, we get a message "battery stats wiped successfully".
So to wipe my battery stats, i found a software in android market called "battery calibration"
Just download this software from market (its free) and you will get your results.
https://market.android.com/details?id=com.nema.batterycalibration&feature=search_result
I plugged in the cable to get to 100% charge (4250mV), I clicked "Battery Calibration" then waited until it was done and unplugged the phone. Then it was at 99% wtf. What does this mean? Is my battery calibrated now or what?
Multiple posts on here full battery reads 100-97%
Battery is only calibrated after battery stats wiped battery drained and charged to 100% then phone used for two weeks .

Thanks for the info, man. So, now that I have calibrated with this app, I just have to drain the battery to 0% - then the phone turns off automatically - and recharge till 100%, then it's calibrated? Woah
PS: Do i have to recharge my phone while it is on or better while it is off?
Galaxy S 2.2.1 firmwares never show 100% battery life when not on charger. As soon as u unplug ur charger the level will drop to 96% or something. Reconnect ur phone to charger again and after 5 mins it ll again show 100% than again as soon as u unplug it, the level drop down to anywhere more than 96%.
just untick wait for 100% option in battery calibration software and ur battery ll be calibrated. do once ur phone is fully charged and once when ur battery level is just 1-2%
Actually its down to the modem version you run.
I ran one modem version that gave me excellent battery life (near on two days of constant use and only 50% drain. Also it STAYED at 100% for about 20 minutes after unplugging if i didnt use the phone, when i used this modem.
The problem is that to get better battery life you have to compromise on signal quality on the modem. The less battery the modem uses usually results in less signal strength, because its not using as much power to find its mast.
read #11 in "Getting the most out of your SGS" thread. That section is on why it's not good to overcharge your battery.
11. Do NOT overcharge
--Why, when, where: Almost all new batteries have an overcharging protection. This means that the protection that is built into the battery will not let it charge to 100%. This is a feature, not a bug! This will help prolong your battery life while also keeping it safe from overheating/explosion/etc. Do not try to trick it and unplug and plug again until you see 100%, just get used to the fact that you can't have 100% battery anymore and live with it, or you risk destroying your battery.
My device only goes upto 4170mV.
Anybody has the same issue?

PROPER battery calibration... is getting on my nerves :/

So, I am using MIUI 2.1.12 with LorDModUE 8.6 CFS 2WCR kernel.
I have installed 4EXT Recovery Controller and CurrentWidget.
With CurrentWidget, I monitored the battery while charging until it reached 0mA (which means the battery is as full as it can get).
With 4EXT Recovery Controller I removed the batterystats.bin file.
I drained the phone until it shut itself down. Then I charged it (without powering it on) until it was full (LED was green).
I power on the phone... 99% battery.
I plug in the charger... it says 26mA (which means it would reach 0mA as in full charge in another 20-30 minutes).
WHAT THE HELL?!
This never happened while I was using the default CM kernel included in MIUI. Only happened with Tiamat and LordMod.
--
Seriously, guys, what is the best way to calibrate the battery?! Perhaps I should not have let it shut itself down, but plug the charger when the phone was at 1% (which lasted for another 20-30 minutes, by the way)?!
if I don't remember it wrong the LED turns green at 90%.
afair the battery doesn't get charged during booting. which means that you probably lost the 1% during boot.
I also used the same method and got it calibrated correctly
but is their any other way too ?

The LED turns green on AOSP ROMs at 90%, when the phone is ON, as far as I know. When it is OFF, it works fine (goes green at 100%).
I want to hear from the developers / those that know how these codes work and stuff... Cause I don't want to look at my phone how the percentage goes down so fast, then, when it reaches 10%, I can play Pocket Legends for another 20 full minutes -.-

The battery doesn't charge to full capacity first time around. When I used to calibrate the battery I would charge until it was drawing 0mA, then reboot; it would be drawing about 26mA, so I'd charge to 0mA again and reboot; it would now be drawing about 15mA, so I'd carry on charging to 0mA, reboot, repeat, repeat and repeat until it eventually continued to draw 0mA after a reboot. Then I'd delete the batterystats.bin file.
As one of Google's engineers says, deleting your battery stats isn't going to improve your battery life. I haven't done any of that for a long time now and I've noticed precisely no difference (except for the extra time I've gained by not having to wait for it to finally charge up to full capacity).

I know about Google's statement.
The battery would drain fast, then, when it reaches 1% or 5%, you would be able to use your phone like it had 30%. Just that it shows the values wrong. Calibrating the battery should fix that...
Anyway... I'm not going to struggle any further.
I'll tell what I've done;
- I have installed Battery Balibration app and CurrentWidget,
- Waited battery charging till reached 0ma,
- Removed battery stats and restarted,
- Then waited to drain battery and shut-down itself,
- I connected USB charger to PC and TURN ON THE PHONE !!
- Again waited battery to reach 0 ma,
- Then plugged off and monitored that current widget shows the range btw 3-10 !!
I don't know exactly if it helps but, maybe you should turn on your DHD while carging..

Sorry if my question is a silly one...
what's the point in calibrating your battery? I mean... except for the stats (and I guess, the percentage in the bar), do you improve your battery life by calibrating it?

I don't really know. It would be silly for the Android system to display the battery percentage (up there, in the status bar) by reading the batterystats.bin.
My phone's battery level drops somewhat fast, then, when it would reach 30% or so, it doesn't drop as fast. Also, at times, when I reach 10%, 5% or even 1%, I am still able to play an intensive game like Pocket Legends for an extended ammount of time (30 minutes, for example). Pocket Legends is CPU/GPU intensive and it also requires an active Internet connection, so I'd say it's pretty power hungry.
I don't really get the entire purpose of calibration. I have done it and I can't seem to notice any difference.
I'm going to do it again, now, because I switched to a Sense ROM (RunnyDrOiD). I'll monitor the battery with Battery Monitor Pro. When it reaches +0mA, I'll reboot and so forth so forth until it's drawing 0mA, although I doubt I'll resist that much time, so I'll just delete the batterystats.bin after a few reboots, when it reachs 0mA.

If everybody knew the meaning of the word "calibration" then nobody would talk such nonsense.
Calibration improves the accuracy of the percentage shown!
The illusion is that you improve your battery life with it....

As I said... calibrating the battery may fix the "problem" where once you reach 1% / 5% you can use your phone like it still had ~20%.

Hi there people, I didn't find any battery thread similar to what I'm going to say so I'll spam a little bit
I've just found as I was fooling around this: http://www.ebay.com.au/itm/PowerSki...AU_MobilePhoneAccessories&hash=item20c1a1c8ad
It suppose to be a silicon case with a battery build in(1500mah ..not bad), I don't know the dimensions but I just someone might think it as a solution to our 1230mah small battery(with this you have a total of 1730mah which is plenty)
P.S. To mods.. feel free to delete my post, I just wanted to inform the people about a solution that might be handy

Terrible problem battery

Hi!, im terrible problem for my battery
a long time (1 month) i bought two batteries for nexus 4 Originals, but the two battery only charged to 91% (long time jump direct to 100%) but low charged 9% without reazon
im try all for the solution the problem:
Reinstall kitkat 4.4.4 from adb
Franco kernel
CWM don't option wipe battery
Calibrate battery too, failed.
ideas please, im desesperate.

first of all try a battery calibration program like this: https://play.google.com/store/apps/details?id=com.nema.batterycalibration&hl=en
maybe it is a calibration problem.
as far as i know batter stats are not erased with a factory reset
then try an app like this :https://play.google.com/store/apps/details?id=ccc71.bmw&hl=en
it should tell you the battery capacity and see if everything is working as it should.
good luck! i hope that will solve your problems, or at least find out what your problem is!
P.S. if it is an app related problem, or wakelock related you can find it with betterbattery stats.

That battery calibration app is a placebo. The batterystats.bin file doesn't do anything to change the microcontroller inside the battery pack itself.

Allow the phone to discharge fully until it turns itself off, by normal use and not using a battery draining app (or a benchmark). Then charge slowly and continuously until full, without making the battery hot, eg. by USB port on computer.
If you discharge too quickly you risk getting the red light of doom.

Last few percent takes longer to charge, I think this is by design. Mine behaves the same way.
