[Q] battery percentage not accurate

Hi Guys!!
i've done what this link told
http://forum.xda-developers.com/showpost.php?p=10092321&postcount=11053
but everytime i reach 100% and unplug the charger, my battery percentage immediately shows 97%, be it charging with the phone off or on....
i already did wipe my battery stats in recovery a few times, the first time only it showed that the stats were wiped, after that every time i wipe the stats, it immediately goes back to the previous menu, without stating whether the wipe was carried out or not....
can someone help this noob out here.... thnx

FYI, i just installed darky's rom v8.0 with Voodoo's kernel 5.2(lagfix disabled)
when i was on stock, my 100% could last me about nearly half an hour

I have this problem too. (I am on Darky 9.02 and have seen it in Darky 8.0 too). BUT if your battery life is satisfactory then don't worry about it.

hows the performance on v9.02 bro?

9.02 is good but then so was 8.00. I personally think 8.00 was faster but its only been a few days and am still experimenting. I may remove the lag fix and still need to see if my battery is draining faster.

Also look at this post: Has some interesting but unverified info about the drop from 100% to 97/98% after unplugging

Do you really want it on 100%? Easy, once it says charged, leave it on the charger for another hour and when you unplugged it should stay 100 for a while

Problem posted hundreds of times along with solutions like search the Rom makers forum and read the posts re this problem for starters .
Simple solution save time and effort is to ignore it .

thanx all for the advices.... tried the QueenAmy method, result is:
heavily used phone: battery 'died' at 2%(???)
charged phone until 100%(phone off)
switched phone on while still charging: 97% (didnt have to unplug charger)
waited...then it went from 97% straight to 100%.(funny)
then went into recovery to wipe bat stats.
rebooted and unplugged charger, battery still at 97%....
now trying to charge a bit more longer to see if can change anything... (fingers crossed)

not working bro...
left it on for about an hour, unplugged, straightaway the percentage drops to 98...

It's just a change in 2.2.1.
In 2.1/2.2, they 'stretched' out the battery life a bit to mark it up to 100%, in 2.2.1 they decided to just show it at the actual value. The reason your battery won't charge to 100% is to prolong the battery life, because if the charger always charged to 100% it would have a high chance of overcharging and damaging your battery over time.
There's no real change in battery life.

I reverted back to 2.2 and still have the problem. Maybe i shouldve flashed on 100% battery... Is it possible to solve if i do another fresh flash with 100% battery?

Just to clarify this, you actually cant over charge the battery on the SGS nor Li-Ion for that matter, what happens here is that the battery goes on trickle charge pre 2.2.1 and battery degrades faster if its kept at 100%, 40% is optimal for storage now with the recent changes the phone will pretend it has charged upto 100% but will stop anywhere from 99~97% yes there is no loss in battery life but dont consider 97% as the new 100%, theres already a 3% loss in this to begin with.

[Q] Extreme battery drain

I am experiencing an extreme battery drain with ALL the roms i tried.
The battery lasts maximally 5h, with 20-40mins of 3g browsing.
Currently at 38%, display max brightness, 2h 12mins usage,78% in battery use / Opera Mobile usage 22 m
ins, 9% in battery use.
13h since last recharge (i went to sleep).
Also my battery magically charges itself while on standby, up to 4% per hour.
Im pretty sure my battery is calibrated, even if it isnt it would give me the same power.
Also it heats up to 59c (even when i wasnt on 1.2GHz kernel)

I think u need a new batt. Same thing was happening with the iphone and untill i've replaced the bat the same thing happened.

.
Thought so.
Will flash stock 2.3.5 or should i flash 2.3.3, which is the latest official for my network?
I think it doesnt matter...
Well the guys in the service are a$$es so it will take them about 2 weeks for it...

i'm not sure tere is such thing as stock 2.3.5 and i think only MIUI has this. Last is 2.3.4 but i might be wrong.

There is xxjvs that is a 2.3.5 firmware

No your battery isnt wrecked neither magic took place its just that ypur battery stats are messed up!
Fixing them-fully recharge your battery until it shows 100% then switch your phone off and then let it charge for another 1 minute then go to recovery mode( you have cwm recovery right?) Then go to advamced then delete battery stats from their and reboot your phone ! Then for best result ypu can fully drain your battery to nil unt it switches off! Your battery stats should be now fully fixed ! Dont worry for deleting battery stats system will make them again in a few minutes or on a reboot !

[Q] just wanna ask x8 battery life

hello
i just wanna ask something about my battery life on my x8...here's how it goes first i fully charge my battery up to 100% until it says on status battery full...then i unplugged it..after it i texted for a few minutes...and i check the status of my battery and it says: 28 mins 23s on battery..my battery is on 96%..is this normal.? or somethings draining my battery,?
i use minicm7 2.2

this is normal since battery is heating itself while charging, and when it cools down it shows less percentage of itself... to maximaze your current battery life, calibrate the battery:
1. charge it to 100% no more no less
2. leave the charger PLUGGED IN, and reboot to CWM
3. there you should find somewhere under options or advanced "wipe battery stats", and you press that
4. reboot your device and when it starts up it will show about 91%, charge it to 100% and you have your battery calibrated
NOTE: the charger is always plugged in

ok thanks i'll try it... one question should i drain the battery before calibrating it.?..as in zero percent??

Yes , that is recommended.
Also , one advice from me.
Even after calibration , whenever your phone says 100% charged , reboot it while the charger is plugged. You will get the exact battery charge after reboot.
Do it every time your recharge your phone.
Then stop rebooting when you get a 99% or 100% after a fresh reboot. Trust me , it helps.

ok thanks for the advice i'll try that too...

it is normal dude ....mine is giving 1day on heavy use

use zepplinrox's supercharge script...it really made a CONSIDERABLE change to m battery usage time

I have one question: "Why my battery is giving 6-8h. My battery 2 days ago giving 24 and more hour." Sorry for my English, but i am from Poland

what happened 2 days ago? did you install new ROM?

The OP might not have needed to install a new ROM, just an APP or maybe just a combination of APPs running. My phone sometimes canes the battery in a couple of hours from 50% to nothing for no apparent reason. On both stock and custom (actually better battery life on custom) it lasts about a day but sometimes about 6 hours! Not sure what is going on as this happened on both the stock 1.6, 2.1 and the custom 2.3.4!

Notification of full battery

I've used several ROMs, and now I'm using Kernel Alfs V09A with GingerDX V026.
In any ROM, I noticed that the X8 always charge the battery until full and then back to 96% and carries up to be filled over and over again.
I wonder if there is a way to notify the phone when it reaches the full level, by sound or vibration.

Yes there are some programs!

Maybe your battery is not calibrated right. Try calibrating with this method.
From GingerZaraki thread:
1. Charge your phone up to 100%
2. Go to CWM Recovery with the charger still plugged in and wipe battery stats and dalvik cahce
3. Reboot and you will notice the 100% battery has dropped to about 96%. Let it charge till 100% again
4. When it displays 'Charged', pull out the charger and lave the phone alone for about 5 minutes.
5. Use the phone like normal and make sure you drain it to 0% before charging in the future (let the phone die out by itself when it's 0%)
6. Charge it to 100% again and repeat step 4 again.

[Q] Battery problem, drops to 0% randomly

I'm aware that this problem has happened to others, and I have seen solutions for this problem, but every fix I've come across works temporarily...and by that I mean a day or two.
While using my Atrix HD, when the battery reaches between 20-35%, the battery will suddenly drop to 0% and shut down. This usually occurs when I am using an app, such as MixZing or the camera app. Any attempts to turn the phone back on cause it to shut off again as soon as the boot animation finishes. The only way to keep it on is to plug it into a charger, and when it does boot, the battery shows the same percentage it had when the phone conked out on me. I've even tried calibrating the battery using NèMa's Battery Calibration app, and the problem still occurs...mainly because I can't get the battery to drain completely so I can properly calibrate the battery.
Long story short, I need a fix, or at least a suggestion as to how I can keep this problem at bay. Does anyone have information regarding this problem?

did you ever wipe the battery data when you flashing a new rom ?
I think you need to re-reconigz the battery .

Agree. In cwm there is an option to wipe battery stats.
I had a similar problem with my HTC First where at 25 % it would go straight to 10 an then to 0 in like 30 seconds...although that was on stock rom...

Do you have the m40 battery mod from maxx?

Just curious

I don't use the eb40 mod, it's all stock hardware. Haven't tried wiping the battery stats, though; can't believe I overlooked that. I'll give it a shot and see if it does the trick.
EDIT: CWM doesn't seem to have an option for wiping battery stats for this phone; I've tried three versions and none of them give me that option.

I suggest you first write down the current battery volume , for example , now in the system ,you can see 60% battery left .
then you shut down the phone , connect your changer , the phone will change and the battery volume show . if this volume is not equal to the No. you see in the system , it means that your system have a wrong battery data record .

Shut down my phone, battery was at 91% (had charged it overnight). Plugged it in and the charging screen showed 90%. Is that what you were talking about, with the two battery volumes not being the same?

I think it's fixed!
I did a full system reset (including formatting the system, which I apparently had yet to do throughout all this time) to install a new ROM. Today the battery drained all the way down to 2% while I was browsing the web (something that normally would shut off the phone at around 30%) before shutting off. It seems that by skipping that crucial step, the system could not properly read/calibrate the battery when installing a new ROM, which may have caused this problem.
I think it's safe to say it's fixed. For now, at least, but I'm remaining optimistic. Thanks to everyone who pitched in with an idea or just said a few words; great to know people care around here.

I'm glad that you fixed it. I did the same but I still have that problem. When It's 20% it drops to 15% and then to 5% in 30 seconds.

Thankfully, I haven't had it drop that low that fast. Of course, this IS the Atrix HD, which carries such a weak battery compared to other phones in its class. Nevertheless, I feel great knowing that my phone doesn't shut off so unexpectedly. If it happens again, I'll do my best to deal with it, but for now...it's just success.

I had this problem after i force rebooted my phone, it got stuck at 1% when charging for almost 15mins. I had to turn the phone off.

for my understanding ,before you shut down the phont , you saw the batter volumes in system is 91% , and then you shut down the phont ,plug it in , and see the battery volume is 90% .I think in this situlation , the battery record in your system is correct ,cause 90% and 91% almost the same . I think your battery is dying , you should replace your battery

Well, a couple weeks later and I'm still not having the problem. The battery does still drain relatively fast (I go from 100% at about 9:00 A.M. to 35% at 3:00 P.M, with minimal usage such as checking Facebook/Twitter and stuff like that), but that's mostly due to the small battery capacity. The battery health is still good according to the scans and hardware checks I've done. I may, however, look into trying the EB40 mod if it means the battery will last much longer.

did you ever try to flash a new rom , you can try , if the problem still there , there is no doubt that the battery is bad .
