Hey there,
I'm using a battery from Polarcell for my SXL. I really like the battery, but (It's a known issue) it doesn't charge to 100%. It always stays at 89%. Every App I found which is calibrating batterys can only calibrate if it's charged up to 100% or it is for another phone.
Nothing is wrong with my battery, it's working very good.
Can I get my 89% full charged up to 100?
(This battery has 1800 mAh. The stock has 1600 - so 1800/1600=0,89=89%)

The last couple of days I've got a weird problem. When my battery is fully charged everything seems okay and it drains in normal speed (compared to stock).
But when my phone runs out off battery and i start to charge in the beginning everything seems fine.
But suddenly it can go from 75 to 100% in 1 minute.When i look at the stats in MIUI ROM it seems like it's not at same height as it was the last day of 100%. Maybe only 80%.
Sorry for my bad English, but i hope it makes sense.
I've wiped battery stats in CWM. But is it possible that the phone actually is only 80% charged, even though the indicator shows 100% after wipe?
Because if the ROM think the battery is charged and wipe stats it will afterwards only charge to that point and the battery maximum will decrease over days?
If that's possible, how do i full charge the battery? Just leave it in the charger or?
I hope you can understand what I mean.
Thanks in advance
Hello
Does your phone charge to fx 75% and after that doesnt get higher until after you restart the phone?

Yes excactly. But the numbers differs.
Today it charged to 100% though.
Got the same problem?

have you try calibrate your batt again
yes my friend have this problem too, maybe there is software bug
After flashing Celebration HD 2.0.1b I first used Battery Calibration from market to wipe battery stats. Afterwards the battery indicator problems started.
Yesterday i decided to wipe battery stats manually in CWM and drain to phone to 2% before charging, and afterwards I was able to fully charge the phone.
So maybe the bug in is Battery Calibration app?
I decided to install Juice Plotter to monitor the battery and compare it to one build in in MIUI. Just to get some more data.
Hello again
Yes i had the same problem as you, with my previosly 2 lg optimus 2x, and returned them because of the problem you mentioned. I am on the third op2x and luckily this work good
So if i were in your position i would try to go to the dealer and shift the phone with another lg optimus 2x.
Best regards

The user said that he started to have problem after a new rom and wiping battery stats, changing phone for that is not the smartest move at all. Is like changing phone because your rom doesn't work.
I have a similar problem, after you wipe battery stats you don't have a reliable indicator, for me the phone took 3 hours to get from 99 to 100%.
I also noticed that my miui ( 1.8.5 same for 1.7.29) doesn't update battery stats when the screen is off so all those plotter don't work, and i think this messes up with the battery indicator (I guess the phone doesn't have enough data to make a decent estimate)
I think is miui + wipe battery stats that can be problematic
I know that but i am just saying that i also had the same problem with the stock rom.
Best regards

How old is the battery? How many cycles does it have?
I know from laptop Li-Ion batteries that the voltage vs. capacity is not linear.
When discharging, the voltage will steadily drop to a "wear-level" where it will jump to an almost depleted level. When charging, this "wear-level" will be at the top.
Why I am telling this? Because if this mapping is kept in SW and you wiped it, Android needs to relearn it again. So at 1st complete charging/discharging you would see a % sudden drop/raise, but at the next cycles it would be linear with time (although the total time will be smaller than a new battery).
When laptop/phone battery tips talk about calibration, it is so whoever monitors the voltage (circuit in battery or SW) to know were the wear drop will be, so your estimates to be better.
As an example, I had a very old Thinkpad that did not have any calibration, and it would discharge to about 40% and drop to 5% within seconds. But when charging, it would raise steadily to 70% (from that 5%) but 70% to 95% in seconds. After years of use, that percentage gap would just increase (40-5 got 60-5, 70-5 on discharging).
PS: my current Thinkpad has 4 years and the battery capacity is 49% with 150 cycles. But this one has a nice feature where if the battery was above a certain percentage, plugging AC would not charge it (and thus save a few cycles). I used it set at 70%.
PS: LiIon batteries have cycle count, heat and time as main enemies. Also don't like prolonged (think storage) low charge.

I was just wondering, if i accidentally calibrated my battery when it was at 60% will my phone now never get the full use out of the battery? or if i charge it all the way and calibrate again will that fix it?

Just do it again when your battery is at 100% and it should fix it.
Download a widget from Android Market that shows your current flowing to your battery.
Like Currentwidget...
If you calibrated on 60% your phone will now show 100% when it actually is not full...
Best thing to do is to leave it charging for minimum 3 hours, unplug the charger and then replug and use the Currentwidget to monitor your current...
The moment that the current goes from positive (green numbers) to negative (black numbers) you need to recalibrate your battery.
Then you will have the real 100% back...
Hi there
i bet this is the 1290312 thread about batteries but i can't find the one that suits me.
so here is the deal with my alfs06 and gingerdx021 x8: when i am charging my phone, the percentage goes high reeealy fast. when it reaches 99% it stays there for a while (30min) and after that it is completely charged.
i was thinking that i have a problem with battery calibration, but i fully charged my battery and then deleted battery stats in CWM, but still no result. what do you guys suggest?
fact: if my battery display is, let's say 16%, if i reboot my phone it goes to 19%.
after batterystat wipe you must charge the battery 3 4 times to calibrate it. it will takes a while.
thanks for your reply. i will charge it and post after a few days if the issue persists.
Hi
My Nexus One just completed one year by this july.
And my problem is that My battery switches OFF at 23% battery.
That is, when it reaches around 23% it suddenly show 0% and switches off.
similarly when i charge the battery after around 75+ % it suddenly jumps to 100% percent and says charging completed.
I tried manually deleting the battery stats file.
I tried the Battery Calibration tool.
I tried charging the mobile to 100% as soon as its starts to shut down.
But still the same issue.
Is there a way to calibrate it or do i need to buy a new one ?
My rom : OxygeN1mod
I am getting around 6 to 8 hours if i use Gprs or wifi.
Another query :
in ebay.in 3200mAH battery is 9800 INR which is too high for me ( i bought my mobile for 14000 INR)
1400mAH battery is 2400 INR.
So is it better to buy a spare 14oomAH battery or a 3200 Battery ?
Please help me.
THanks in advance
Any one , please help
Tha'ts not normal if it's shut down at 25% ! ! !
Normally at 10%
Should buy à New One
If you don't care about the design of your n1. I suggest you the 3200 one

I heard that you can't fully charge the battery while the phone is running, it has too leave room since the battery is in use at the same time it's charging so it wont overcharge and ruin the battery.
So I was recommended to shut the phone off once in a while to charge the phone to full 100%.
Mine is now starting to die at around 20% but when new it died around 10%, newer lower.
But then again the battery could just be going bad.

Install de battery calibrator (for nexus one) search in the google play
Verify the field "battery age" and set to 100%
Reboot and give a full charge
Drain normaly the battery, and look the percentage of the shutdown
If your phone shutdown on the 15%, set the battery age to 85% (100%-15%)

So when i had note 8 after battery replacement i installed accubattery to see how battery health was. I see 2982. Now i fully charged to 100% with fast charge about 1 week every day. So i see now 3324! But real battery capity 3300. How recharged battery? When charged via normal charged usb not fast adapter, i have fast charge and i can disabled via settings. So on another phone i charged without fast charfe so i had 2430mah when reached to 100 it dropped down to 2400mah. Because slow charged and full reached charger. Sometimes i charged until 86% so increase mah battery. But on note8 i see overchargerdd on another phone i wiped cache accubaterry so when i turned on battery to see how battery left mah shows 2572 when i insert to charge the phone . So accubattery bugs?! Now shows on a8 normal! 2410mah 79%battery left health
Use aida64, its more accurate. To check battery cycle, use devcheck.
Devcheck shows 9 charge cycle but not shows how battery health

9-10 cycle shows that you really got new battery. Just check their capacity with aida64. You should get arround
3100-3200 on android pie when you fully charge it.

Yes the battery was new . When i got i installed accubattery app to see how much health left when insert new battery! Shows 98% now i charged a day about 2weeks to 100 with fast charger and without fast cable. Sometimes percent in accubatery app dropped down . But now shows 3331 mah 101%!!! I charging to 100% but the procent dont dropped down . Proceng should be down about -500mah when charged to 100. On another phone when i charged to 100% i see dropped -500mah. When i charged to 80% battery health extended! But on note8. Overcharged 3323?? Actually 3300 mah. But why shows accubattery 3323? I charged fully when i got new battery. And now still charging to 100 on every day!
My battery discharged in 10 hours with 7% brightness . Sometimes i used 4g. Screen on time 5hours a day. Normal? Nfc off ,location off. I trying with power safe mode!

But how about 101% battery health? Shows 3331 battery but battery is 3300! Overcharged? This is bad for battery? I got new and it was 2972 battery when i installed accubattery! And i charged every day to 100. With fast charger and via micro usb, and with disable fat charge but i charged via fast adapter

Screnshoot your full charge battery capacity with aida64, we will knows exactly how much it is. Accu battery is base on observation, not directly by battery reading.
I got 600+ cycle and 3139 mAh, but still got 6-7 hour SOT usage.
