How do you know when an Extended Battery is full charged?

I just bought an extended battery (the Sprint Store one) and when it stops charging, it doesn't show the number of chargness anymore and it doesn't show the lightning bolt on the battery once the LED light is green. So do I just leave it overnight to charge?

It will be charged by the time you wake up in the morning lol

You sure? It doesn't show the charging icon on the battery... And I doubt a bigger battery would charge that fast?

Why don't you download battery monitor widget its free and shows all stats.

Once you install it, just go into.settings and set update intervals to 60 seconds.

It will still reads the accurate mA's + and -, why not just check the stats and watch when it hits 0mA's.

so you have to have sbc to get a full charged? coz witout sbc it will not read 0

Yes... SBC will get you maximum charge... if you don't use SBC then what you need to do is follow the instructions located here:

Personally, I love SBC kernels. I've never had issues with them at all and it works great with my 3500mah battery.

It will not pass 1500 unless you use sbc, the stock kernel will stop at 90% but say it's at 100% to prevent overheating. So technically your initial drain will be really fast cause when you unplug your phone its really on 90% and not 100%. My phone has never overheated or any weird issue you would expect to happen.

The ONLY way you're going to get full potential out of your battery is by using SBC kernels. HTC has a charging bug where it won't let you charge past 1500, so technically it will stop(go green) you at about 90% but shows 100%. Check out this thread with a bunch of kids using 3500 batteries; they're mad because they can't charge to 100% but if they use sbc they wont have that problem lol.

Here's some info about kernels/sbc
http://forum.xda-developers.com/showthread.php?t=894880
To flash a kernel you need to make sure you only flash a sense kernel for a sense rom and aosp kernels for aosp or you phone might not boot beyond the evo logo(nothing major its easy fix). You find a compatible kernel and grab the package and boot into recovery and flash it. I'd recommended wiping dalvik cache after flashing a kernel.
Instructions

Here below is the direct link to the kernel that I would recommend for myn. Its the netatchy toast mod cfs with hdmi built in. Good luck

i dont know but its been a day and im still at 50% so i guess i dont need sbc

I have the seidio 3500mah extended battery and they recommend charging an extra 2-3 hours after it says full. I've found this to be true; if I pull it off right when it says full it will soon drop anywhere from 30-50% of the charge.

Yeah if its sleeping 80% of the time then I would expect it to last that long but not for heavy users.

I got two extended batteries. One in the phone and one on an external charger. I never use the cable to charge anymore. I just swap the batteries when my phone dies.
Sent from my PC36100

I also have the Sprint extended.
I see people saying that the battery won't fully charge without SBC. Completely untrue.
Also untrue is that the phone will not charge past 1500. This doesn't make any sense to begin with -- why would they sell extended batteries if they don't work...? Or why would they sell it if consumers needed a special kernel that you can only get if you're rooted?
Perhaps the reason the people with 3500 batteries don't get the full 3500 charge is because most of those batteries aren't even 3500.
----
You need to cycle charge it a few times and then you'll start seeing the battery life go up. I can get at around 2 days with light usage now.
----
Honestly you don't need an SBC kernel at all, though it might extend the life a bit. It's completely a preference thing...

Is battery calibration necessary?

How important is battery calibration using the apps in the market? This whole past week has been a flashing frenzy I'm sure for many of you, without a real break to calibrate battery before you flashed the next newest release.
I've lasted the same rough battery life without wiping batt stats, using a battery calibration app or cycling to 0% and all seems fine, so I'm wondering what the importance of it is.
Sent from my SGH-T989 using Tapatalk

Just use the phone and charge the battery as needed. These batteries don't need calibrated. I have 3 and charge them all differently and they all get the same type of life.

But when you flash a rom be sure to give it time like 2-3 days before you judge battery life sometimes old battery stat files stick after flashing so make sure you calibrate these batteries as least once a month.

I use Battery Calibration everytime I flash a new rom... Isn't that what we are suppose to do?

Yes u should calibrate.. for example using stock roms for weeks I never calibrated.. got 16 hours. Flashed juggernot and beast mod got the same battery life because I didn't calibrate.. after running beast for 2 days I did my first calibration and a day later I was pushing 30 hours on one charge.
After u flash a new rom or kernel you should calibrate

Wtf? So what's happening? Is my phone ACTUALLY going to zero or its assuming i've hit zero after (X) hours? Once I calibrate, the phone should know that I haven't burned as much as it thought?
And this is after EVERY rom flash? Gets tedious?
Sent from my SGH-T989 using Tapatalk

Okay, no wonder why. Thanks for letting me know!

You're just calibrating efficient usage of power..
If you're battery is used to giving crappy life even on a great battery rom it'll drain quickly

Sent from my SGH-T989 using xda premium

Screw calibrating and screw wiping battery stats. Use your phone as you normally do and battery life will maximize on its own with a couple charge cycles anyways. If you have battery life issues its much more likely to be an application, rom or kernel issue.... when all else fails then look to calibration or wiping of battery stats.
If you don't agree then feel free to waste your time calibrating every time you flash a new rom.

can you tell me where you bought your batteries from? I've been looking on the web (ebay) but there's so many varieties and the prices differ widely from $10 for 3 to $40 for one. i don't want to spend too much money on extra batteries but i also don't want to get a cheap one that will mess up my phone either.

[Q] Battery Graph jumps up at the end

It's hard to see, but the graph jumps up at the end. It happens almost every time I charge the phone. The percentages that the phone is displaying would go from, say 92% to 100%, or sometimes 96% to 100%
When it says 100%, the mA is almost always around 40-50ma, regardless of how big that spike at the end is. So I usually let it charge to 0ma, or just unplug it if i can't be bothered.
Yes i've calibrated the battery, many times. Didn't change anything.
I guess it's only really happened on CM7 based ROMs, not on stock.
I don't think it's affecting battery life, it'd just be the UI displaying the wrong info. But I was wondering if there was anyone out there who might know why it's doing this and how to make it stop?! Or has anyone else experienced this?

same thing..40mA on 100%

That's not normal. You need to calibrate the battery. There is several ways to do that. 1. Fully discharge the phone and then let it charge to 100% without break. 2. Use Die-Hard Battery Calibrator (search it).

Did you use it 4 hours with the screen on? The battery stats understandable if you have done that, but otherwise I would recommend you to buy a new battery.
BTW: 1. Have you installed some tweaks? Try to reinstall the ROM. 2. Maybe the game you told us before is using 100 % cpu both when it being used and when the screen is off. Check that with CPU Spy.

I have almost the same problems as you. The phone discharges 40% in like 10 minutes when playing a low graphics game or browsing web. But for me it freezes at a value. For ex: the battery goes from 80% to 40% in 10 minutes than stops at 40% for 20 minutes and so on. I am using Oldroid's CM10.1. I've just reflashed it. And this is my second battery.

No problem

I've got a similar problem. I've installed Jelly Bread v3.5.1 by saldymhmd and Alfisyahrien. I charge the battery until it is 100% charged, then when unplugged it lasts about 30 minutes before the rom shuts down because of the 'low battery status', but if I plug the charger just after that, the battery indicator shows that it is about 85-90% charged, but if I unplug it and turn the phone on, rom still says the batery is low. I tried to wipe battery stats and to calibrate battery using the option in CM settings, but with no avail. Any ideas how to fix the problem? Would the Die-Hard Battery Calibrator fix this?

Replaced Battery twice...strange behavior

I ordered a new OEM battery. Replaced the original. The phone charges normally to 100%, but during use it gets to 20% and shuts off due to low power. Just shuts down. You have to plug it in for about 5 mins before you can even turn it on again. when it comes on it is at 1%. I went back to the provider and complained that he sent me a bum battery....they sent me another....same issue! So I think its a calibration problem.
Anyone have ideas?

where did you buy the battery ?.... sounds like a knockoff battery problem

The only reference I can find to xperia battery recalibration are steps that are for versions with removable batteries or steps that don't work on the ZL (one set of actions including holding the power button and up volume for 10 secs where there is no response from the phone)
Do you know of any process for ZL that is not root required?

i have the same problem as yours,100% same but it happened to me after installing custom rom on android 4.3..
battery jump from 20% to 0% immediately.. with no mercy, phone shuts off at any cost and start again at 1% after turned on and charged.
i still use the original battery (not replaced it yet) and in battery health test said it's good, no need to replace it.
now i'm trying to find the fix by myself.. maybe i have messed up something with my phone..

Here's an update of my device..
Finally, no need to wait for 20% or below to shuts off..
This problem become more critical to my device, somebody help me!

Yes I would be interested in obtaining an "official" replacement battery just in case if at all possible. How difficult is the replacement?

Update 4.4.4 solved my battery problem.. See the graf, it's drop normaly now.

Upgrade to 283 over the air seemed to reset the battery calibration. Now runs right to 0 before shutting down. Still no hell from a total battery life perspective but at least its not shutting down at 12% like it was.
