95%-100% - T-Mobile Samsung Galaxy S II SGH-T989

Hi Guys,
I was wondering if this is nomal. When charging my phone it normlly charges and the percentage moves up in 1% increments. But, when I get to 92%-95%, it jumps to 100% within a minute or so. Is this normal? I am losing 5% of my battery capacity?

no you are not, mine did this the very first time i charged it

Try unplugging it and plugging it back in right away. Is it rooted? Maybe wipe your battle stats. That's where I'd start.

I believe its purposely like that. Most phones does this so that your battery doesn't charge fully as that kills the battery life, therefore usually it only charges to 95 - 98% but will show 100%.

Charging from 95% to 100% takes 2 hours

Well lets say my battery is 35% when i get home, it takes about 45 mins to get to 95% then from there takes about 2 hours to get to 100%. Running CM7 on the Telus DHD.
I dont know if this happened with stock as i rooted as soon as i opened it
Try downloading CurrentWidget and then charge your phone until there are zero milliamperes showing on the widget. Then wipe your battery stats and reboot. This should calibrate the readings to be a bit more sensible/accurate, for both usage and charging.
As the battery is charging and nearing full capacity the current slows down thus making the charging process slower.

It's not iOS, Android or WP7 - all Li-Ion batteries have to be charged that way. Just one of these OSes preffers not to give accurate information to its users about baterry charge, signal strenght etc. What you don't know can't hurt you seems to be Apple's moto. Still 2 hours for 95% to 100% is too much.

About 2.5 hours is what I'd expect it to take to charge from 35%
k well today i got home and the batt was 35% (heavy usage) and it only took about 45 mins to get to 90%. From there it goes much slower.
Going to CM7 I had the same problem with my battery being at 95%. I'm planning to drain completely, wipe battery stats immediately, then doing a full charge.
mine only takes just under 2hrs charging from empty to 100%.
It depends if you're charging it through your computer or the wall. If i charge mine through the computer it takes about 3 hours if the battery is completely empty. If i charge it through the wall, it uses about half the time, but the battery empties much faster. Some phones has so called "speed charging". That means that you can choose between good battery life but long chargr, or short charge time but bad battery life. It depends on how you charge it.
But, two hours from 95% is not normal.

This might be a clue to the cause of the problem. I'm now running stock ROM and being in the process of deciding if I should go for Revolution HD or stay on stock, I read numerous posts of battery stats problems. I think the OP should try to wipe the battery stats and see if that would help.

[Q] Correct method for Battery charge cycle for new One X

Hi,
I keep getting multiple views when search the forum regarding CORRECT method for charging One for first few times and then after. Kindly suggest if you know for sure.
Many Thanks...
as allways: full --> empty --> full
most say two or three times is enough
Do it again when you install a new ROM or kernel

Thanks for quick reply...
don't know which thread but i remember reading about not to drain it down to zero, suggesting to charge when down to around 5%. Hence the dilemma.
Give a hint if you find it again. I haven't read it before
I'm doing as written and have a quite good (in comparison to what you are reading here) battery statistic.
Would you charge it power on or off for first few times?

You have a li-poly battery, and a lithium polymer battery doesn't need any particular charge method or charge cycle... However there's two things you can consider doing for your phone's battery.
1. Charging the phone for a full 5 hour period (even if it shows 100% charged, keep it plugged in to the end of 5 hours) and then wipe battery stat in cwm recovery if your phone doesn't detect remaining battery correctly.
2. Charging it from 50% remaining battery life is much better than letting it go all the way down to empty!
(I know lots of people told you to let the battery drains completely and then fully charge your battery, but trust me, i'm an electronic engineer, I know better, both draining the battery to 0% and charging it to full 100% are bad for your battery life, those were for ni-mh batteries not li-poly)

Exactly. No need to do full charges. Just plug it in whenever. If you are anal, then keep the charge cycling low. Eg keep the battery on a small band of charge state for example 50%-75%.

So, when the phone battery is down to 50%, we charge it.
And then when charged to a 100%, let it stay charged for an additional 5 hours, after that, or 5 hours TOTAL, from the time it is plugged in?

5 hours total, the point of this is to let your battery voltage go to it's maximum capacity (something around 4200mv, you can check the current voltage by dialing *#*#4636#*#* in your phone and going to battery information section)
And also note that full 5 hours charge cycle is just necessary when your phone doesn't detect your battery remaining percentage correctly... In normal situations just charging the phone from around 50% to almost 100% is an optimal charge method and you don't have to do the 5 hours charge...

The point you're trying to make is that for better battery life, it is important to re-charge when the battery falls to 50%, and not wait till it drops to 5-10%. Correct?
For Li-Po batteries, how low is it okay to let it go, before a re-charge?

Exactly...
It's better to charge your phone between 35% to 75% (optimal value is 50%) and not letting it go under 35% but after all as I said there is no need for an specific charging method and this precautions just give you something like 25% more battery life (and battery life is overall life of your phone's battery before you have to replace it, not the 100%~0% duration)

[Q] Battery drop after reboot?

I've been experiencing huge battery drops (from 10% up to 20%) after I reboot my phone. Is this a KitKat issue or is it my battery?
In the morning from 99% (after checking a few messages in the morning), I rebooted and I dropped 11% to 88%.
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one. :good:
I didnt found it on reboots, but i have this problem when i enter recovery. 20 minutes in recovery - i dont hace 20% of battery.

Hmmm that's strange.
I've noticed it usually drops more when I leave my headphones in.
full loaded ACE 2.
reboot cost u 5%
first 10 % gone in a few minutes for heavy users and in a few hours when deepsleep !!
what i wanna say.
the first 10 % gone in a few.
after that normal drain.
I often get this, although not as bad. I usually lose 2-5% on a reboot, sometimes up to 10%. The other week I charged it to 100% when it was off, turned it on and had 92%.
so is this actually a problem or is it normal for everyone?. Mine looses 5-8% in the first couple of minutes after I unplug the charger..

Its normal. I usually lose the first 5% of a full charge in a couple of minutes. After it gets to 95%, battery charge will drain normally depending on usage.

ok then, thanks...I just thought that this didn;t happen when I was on GB, but it doesn;t matter anyway..
If I reboot once, I will lose between 5 - 10% battery. However, if I reboot straight after the first reboot, I will lose between 0 - 2% battery. I've never really understood this.

Battery Charging Issue
Is this normal?
When I charge my battery whether it be from mains or USB computer it charges ok, but as soon as it gets to 100% it still says charging for a little time and doesn't report the unplug charger message right away.
With the Jellybean 4.1.2 system I don't get the alert tone when the battery reaches FULL, therefore I have a feeling that when it still says charging even though it's showing 100% that it's actually decreasing power at that point, any help please?
I have tried other batteries, and one in particular goes from 90% right up to 100% and seems to miss that last 10 percent, so I don't use that one now.
I have the most current firmware installed.

when it says 100%, you still have to wait for a few minutes before it displays the green "full" icon in the upper left corner and asks you to disconnect the charger.
However, the first 5-8% always drains REALLY fast and not proportionally to the rest of the battery drain...
I think It may have been my battery giving me the huge drops. I don't seem to have this issue any more after buying a new one.

what about the initial drain? does the first 10% still drop fast or has this changed too with the new battery?
I just wish that JellyBean 4.1.2 would give an alert sound when the battery has reached it's full limit like Gingerbread used to do.
Who would be the best place to ask them to do this on their next update?
But I think that it does..a very short one indeed, but it does, along with the screen lighting up briefly..

Custom rom has nothing to do with it. I am running the stock version, and my battery won't charge up more than 64% right now. It seems the problem starts with 96/94% but gets progressively worse. Sometimes it will fix it self for a short time when I replug, but right now even that doesn't work for me.
I checked last night, and I believe the kernel just thinks the battery is nearing it's 100% state. This was a screenshot I took that shows that the battery isn't charging at full power. The closer I got to 64%, the slower the charge went:

Have you tried just using the tablet when it was "fully" charged to 64%? I see three possibilities and I would be curious to know was the case:
1) Your battery is only charging to 64% and when you start using it, it will decrease at a normal rate and you'll get 1/3 less time out of the charge.
2) Your battery is showing 64% for all charges >= 64%. So, it could be at 100% charged and will stay at 64% until you've used up 36% of your battery.
3) It is scaling wrong so that 64% == 100% and the battery percentage will decrease as you use the tablet, but it will decrease 1/3 slower than it used to (aka the time from 100% to 0% when you first bought it would be the same as your time now from 64% to 0%).
Any idea which of those three is actually happening?

Definitely the first one. Right now I am at about 35% and have 2.5-3 hours screen time since the 64% (can't check for a definitive screentime as the indicator doesn't reset unless you charge to 100%). So that would translate to the about 7.5-8 hours I get when I do have a full charge.
I also checked once before when I had this issue by letting my battery completely discharge and then start up my tablet again and I had 1% left, so it was pretty much completely drained. I'll probably charge it again tonight and I expect I will have an even lower full battery percentage.
Try using a different 2amp charger and/or different cable

The only real fix for this opening the back up and unplugging the battery. When you plug it back in you won't see the problem again. Not sure why.... But that's how I fixed mine. Been good for two months now.

Also tried that already. Still only charges up to a lower percentage. Only thing I haven't tried is unplugging the entire battery.
It charged up to 100% for some reason last night. The only thing that is really weird that it charged 1% every five minutes from like 85-95% and then suddenly in the last 5 minutes it instantly charged from 95 to 100%. The whole battery thing is just really weird.

Htc 10 quick charging

Hi there,
I just got my phone and I thought the quick charging should charge my phone fron 0-80 in about 35 minutes...
I turned off the phone and from 0-35% took around 32 minutes which does not sound right...
Is it because the phone was turned off?
Or something needed to be set? Its the factory default charger.
Thanks in advance

Did you literally just get it and plug it in, or did you run it all the way down to 0% and then plug it in?

Well, the first thing you'll probably hear around here is never let it discharge all the way to 0% because it's bad for the battery. I'm guessing that, if you did let it go all the way to 0%, it might take a little bit to get going again, so the charging time would indeed be longer.

If you Google something like, "lithium ion battery discharge 0%", you'll find all types of reasons why it's possibly harmful to your battery.
Nope.
Mine charges to about 40% in 30 Minutes. That's normal.

Don't worry about that 0% nonesense.
Smartphones are Idiotproof. You can't do anything wrong to damage them with normal usage.
Yes of course it's Bad for battery life (long term) if you drain it to 0% every day but until 4% is completely fine.
Why is it Bad to drain a battery to low? Take a look at the battery Voltage Graph in my Charging Chart. Charging is even more Voltage than discharging. If you use and App to check battery Voltage you will see about 3.7V at 4% and it Drops to 3.6.... 3.5..... 3.4V the closer it gets to 0%
Batteries don't like that.
Feels like my nexus 6 charger charges faster than stock HTC 10 charger

OK, quick look.
A Li_ion battery has a life cycles 400 - 500, that means battery can go from 100% to 0% normally 400 - 500 times, after that, battery will start to get problems, e g, you see it's 100% battery but in 30 minutes normal usage it goes to 0%.
If you charge the battery to 100%, then recharge it only if it gets down to 0% every single day, then after one year it's very likely you'll face the battery issues.
Yeah.... so if you recharge your phone not when it's at 0% but at 50% you will have around 800-1000 cycles...
AND you charge your phone about twice as much as the other guy who only charges at 0% so in the end you both end up with the same battery capacity after a year xD
P.S 400-500 life cycles means until the battery has 75% of its original capacity left, and not untill it's totally unuseable
