Ok, so I've been experiencing this for the past few weeks now, and I'm getting sick of it. I plug up my phone to charge it overnight, or just to charge it when I know I will be in a place for a while. After a while, the phones battery will say 100%. But when I take the charger out, the battery isn't fully charged. It IMMEDIATELY jumps down to around 40% - 70%. I can get it fully charged after unplugging and replugging the charger in, sometimes numerous times of unplugging and replugging. Also, my battery has died on numerous occasions on between 10% - 15%. I calibrated my battery the first day I got it (as a replacement) and got decent juice from it, a noticeable improvement from the old battery. Am I the only one experiencing these issues? Is there a fix for it???
*NOTE* I'm on my 2nd battery (replacement) and this is also a replacement phone. Also running GummyCharged 1.8 GBE on EP1Q, RFS, w/Minimal Gummy theme, if that matters. Also, its not just my phone, my wifes Charge phone has the same setup and it does it also. So it may just be something wrong Gingerbreak. Never did it on FroYo. Gonna Odin back to FroYo and report back.

This is because you cannot leave the phone plugged in to charge for an extended period of time. Once the battery reaches 100%, it stops charging. It will start charging again later, after the percentage goes down to a certain set level. This is why you have the huge initial drop-off after taking it off the charger. If you want to leave the phone plugged in for an extended period of time, turn it off and plug it in to allow it to charge, then it won't discharge as quickly. Otherwise, this is normal behavior for all android phones, and trying to make it so that the phone stays at 100% full charge is bad for both the battery and phone.
I've been having some strange problems. My phone will die with between 4-8 percent battery left. I can turn it back on and once it drops another percent or two it will turn off again. I have calibrated it and my battery life is good but this is a strange issue. Upgrading to rc2 today.

I have the exact same problem. It will just go from 50% to 100% in a second and then unplug and plug back in to make it work. i haven't been able to figure it out either. 2nd phone and 2nd battery as well with same issue. I guess it has to do with my habits somehow.

I believe the use case he is suggesting is a little different than what you are describing. When the phone is plugged in at say 12%, it charges for a while and gets to say 63%. At that point it jumps to 100% immediately. The phone must then be unplugged from the charger and re-plugged in and then it will continue properly to 100%.
Hopefully that is a little clearer.
I mean, usually I turn it off to charge. And I have that No Moar Powah app installed. So I set it to reboot at 100%, it does and when I take the charger out, it immediately drops to between said percentages. almost like clockwork. Very annoying. I understand what u mean Imnuts, but my Vibrant, HD2, or others never experienced this issue. Also, my first Charge, would keep a charge if I left it on the charger once it hit 100%. Maybe an issue with the charger itself? A Verizon rep told me to bring in the charger itself if the issue persists.

Almost exactly my issue. I'm not understandings what the problem is. I'm assuming u have that issue also???

Hmm i have the opposite of that problem every time i unplug my phone from charging overnight the battery meter would always read 100% never below that.
Also does anyone know which battery meter i should follow for battery calibration? The battery meter in the status bar, the battery level in system settings/about phone/status, the battery percentage at the lock screen or the battery meter on the screen when the phones off? They're all giving me different readings for some odd reason.
Sometimes I get that too, but for the most part, its the false readings from the lockscreen, and the about phone settings. I may send off for a new phone, run stock for a few days to calibrate my battery then root on a full charge.

I see what you're saying, but on the other hand I charge my phone overnight with no problems. Never did this before, but I don't have time to sit around for 6 hours for it to charge

Well I went back to FroYo GummyCharged v1.9 and lo and behold, the charging issues VANISHED. Charged my phone overnight last night and when I removed the charger, 100%. No drop immediately back down to 56% or some weird number. Maybe its a Gingerbreak leak issue. I've noticed that it only happens to my phone on Gingerbread. Also must mention, my wifes phone does it also. She's on Gingerbread. She complains that I broke her phone lol.
*EDIT* CONFIRMED. 2nd nite in a row, no issues charging.

Imnuts...ill have to disagree with you. This is the only android phone I've had this problem on, and I've had 6 different android phones. also, it only started happening for me when i went to Gingerbread. Going to flash back to Froyo and i will update.
Sent from my SCH-I510 using XDA App
Same here with me. It only started when I went to Gingerbread. Also happened on my wifes phone, also on GB. I went back to FroYo 2 days ago, and boom, no more charging issues. I can leave it on all nite and not get the random percentage drops. I gotta calibrate my battery now.

So it was a Gingerbread bug (GingerBug???) right? My battery life seems way better also. 6+ hrs off the charger and I am sitting on 73%. Not bad for me.

The mis-information in this thread regarding Li-ion batteries is getting out of hand.
I think many of us are thinking about ni-cad batteries in which all the "bad" things we are talking about in this thread apply.
for a Li-Ion Battery, there is no "memory" effect. this means you can charge it at any point during the discharge phase. You also do not need to allow the battery to drain fully and charge to full to "condition" the battery. Li-Ion batteries can be charged at any point up to any point (from 30% to 70%, then 50% to 90%) and it will not effect the batteries performance.
Li-Batteries also do not suffer from overcharging. The charging circuits in cell phones will charge the battery until it is full, and then trickle charge from then on. And because Li-ion batteries do not have memories, this type of charging will not effect performance.
Li-Ion batteries can only be charged a finite number of times. However, the number of times does not translate to the number of times you happen to plug it in. The batteries have a rated number of "charge cycles", this is when the power from the battery has been exhausted and then re-filled. If you always charge your battery at 50% - 100% then every 2 charges you are using 1 full charge cycle. The batteries in the charge are 1600mAh and have approx 500 charge cycles. if you discharged and charged your phone from 0 to 100% every day, your battery would last 500 days before it would start to suffer from poor performance.
the OP in this thread is having software related issues related to the phone mis-representing the correct charge level of the battery, and then stopping the charge cycle prematurely.
Remember, it is perfectly OK, and expected of you to charge your battery as many times as you need to. Keep the thing on the charger any chance you get, it is not going to hurt it, its designed to be used that way. This is why Li-Ion took over as the battery tech of choice compared to Ni-cad.

This coming from a person WHO KNOWS WHAT HE IS TALKING ABOUT is very beneficial to us. Knowing that there is no way to actually "condition" a Li-Ion battery means that us who are actually suffer from poor battery life either have defective units or defective batteries. I hear of this miraculous 2 day battery life, yet I struggle to get thru a full 7 or 8 hrs with moderate usage. And this is a replacement unit AND battery. None of my other phones had that issue of immediately droping percentages like that, so I figured it was a software issue, that's why I went back to FroYo to test it out. Seems I was right. Gingerbread has a software issue that keeps the battery on some phones from reaching a full charge. Also my phone would be boiling hot during the charging process. Since reverting back, I've had no issues. Thanks for the insight. Coning from a knowledgeable source, it means a lot. Thanks!!!

When I first got my Galaxy S3 (Verizon) the OEM battery lasted at least a good 9 or 10 hours, usually plenty to last the day. But I wanted more than that so I got a pack of 2x QCell 2300mAh batteries for cheap on amazon, with one of the wall chargers that you pop the battery into. That was July of last year and I promptly lost one of the batts at school, so in May of this year I got another pack of 2 batts, this time EZOPower, 2100mAh.
Both brands worked pretty well while I had them and I would generally just start the day taking my GS3 off the charger and putting the extra battery in my pocket, and at ~8pm or so I'd switch them out and have more than enough for the rest of the day, and some for the next day if I didn't make it home for some reason that night.
But recently that time to switch has been creeping down earlier and earlier, and lately I've noticed I wake up to the battery icon showing the circle but no percentage (just switched from AOSP to Pacrom, dunno if that makes a difference) and when I take it off it's about 95%. When I switch batts, which is now at about 2 or 3pm if I wake up at 10, the second one (coming off the cheap battery-only wall charger) is at 75% or thereabouts and each lasts less than 5 hours.
Attached are my stats from the other day. I keep all my radios on all day usually but lately I've been having to selectively put it on airplane mode whenever I can afford to, if I want to have enough juice to last through the evening. This sucks. I know batteries die over time but I've literally had these ones for a few months and they're terrible already. Is it because of my hot swapping habits? Does that drive down the battery life over time, or is it something to do with how android pegs the amount of juice left on each battery? Is there a way to wipe the battery stats, or would that even help? There used to be an option for it in CWM but I looked today and I suppose it's gone. I'm not sure what I'm doing wrong but I've never had battery life this bad on any phone.
tl;dr bought a pair of non-OEM batteries with a wall charger, been hot-swapping them for more power throughout the day, but in just a few months their life is approaching nil. What am I doing wrong?
Bump. Anyone knowledgeable on this? I'm pretty sure it could apply to just about any phone and I know plenty of other people do the same thing I do with these battery pairs on Amazon so this would be useful for progeny.
Do you leave them in the charger until you need them? Usually, the longer a battery charges while it's fully charged, the more the total charge will diminish. So, the longer you keep it charging more than it needs to, the faster the battery dies out. Also, when you get a new rechargeable battery, or even a new phone or tablet with a rechargeable battery in it, the first thing you should do is use it till it's drained. Don't immediately plug it in to the charger. Keep in mind, though, that no matter what you do your batteries will diminish. Cheaply made batteries will diminish faster than higher quality ones, so that may attribute to how fast your batteries are dieing.
I could be wrong, though.
I actually do keep it on the charger long after it's charged. And I have heard that before - but don't most chargers have a built in feature that cuts off the current once the battery is fully charged?
Anyway I'm not sure that's the sole reason for the batteries being so ****ty. Although idk, I also could be wrong, lol.
What's the consensus on when to charge and how long?
Is it safe to charge the S7 battery overnight, even if only around 50%? Or is it better to wait until your almost dead?
One of the I.T. guys at work was saying you should wait until you're below 20%, then always charge to 100%.
Just charge it whenever you want, this isn't the 90's or 2010. You'll probably replace your phone before you start to see it majorly affecting your battery.
You'll get a very slight improvement in overall battery life if you keep the charge between 25% and 75%. But we're talking very small. But yes, it's perfectly safe to charge your phone over night. The battery / phone / charger electronics won't overcharge the battery.
What you do want to avoid is draining the battery down to zero, or close to it. If at all possible, don't let the charge drop below 20 - 25% on a regular basis.

Thanks for the info. I thought it was beneficial to charge all the way to full?

Lithium Ion batteries are different than older technologies, such as NiCad and NiMH. These batteries suffered from the "memory effect" (although not as badly as most people thought), so it was good to charge those fully. If you always charged them to, say 80%, they would eventually only take an 80% charge. Li batteries don't suffer from a memory effect, so you don't need to worry about that.
The other thing is that Li batteries hate three things: excessive heat, being fully drained, and being overcharged. Tesla stops charging when the battery pack reaches 75% of full charge, and displays that as a full charge. Similarly, they consider a 25% charge as "empty." Then again, a Tesla battery pack costs something like 10,000 bucks, so it's important to as much as possible to maximize the life of the pack.
Do you use the 85% charge limit?
i personally think that 85% is BS i have had god knows how many phone all charged to 100% every single night and ZERO! issue. and limiting this phone specially to 85 is a big cut in the hours you will get.
Not a chance. I'd hate this phone if it only charged to 85%.
I Use it all the time. 85% is enough Juice for one workday and i simple want the battery to last as long as possible. I have had bad experience with batteries dying after ~3 years.
The 85% Rule is no BS. You also have to keep an eye on minimal SOC and never go under 10% to avoid unnecessary battery degradation. With that your battery will perform according to the specs (~700 cycles until 80% SOH, modern smartphone batteries). Otherwise it will suffer and that reduces cycle life. This is simply the state of current lithium battery tech.
From my pov, a full day usage requires 100% of charge because some of them cannot charge the phone while they are outside the whole day.
I have wireless chargers almost everywhere, so when my phone is not being used it's normally sitting on a charger. That means that it very rarely uses much charge, so charging to 85% is fine by me. If I knew that I was going to be away from a charger for a protracted period, then I'd probably charge to 100% beforehand.
I can't get too excited about battery management. If I need to buy a new battery for my phone at some point in the future (it has never happened yet...) then that's what I'll do.
i use 85% because i have quick carger in my car and it charge all the time.
at home I have wireless charger and when i need i put it.
I tried it for a few weeks and instead of having 80% leaving work I was at 50%, not really worth it since I'll probably have a new phone in six months. It was too much of a headache stressing about battery life without the phone fully charging.
No, I charged to 100%.
