Charging with chargers - T-Mobile Samsung Galaxy S II SGH-T989

I have 2 t989's, one as my phone and the other as a charger (so I can always have a 100% fully charged battery ready to go instead of leaving my phone to charge and missing calls n stuff). I bought a 6ft charging data usb cable cause all my other chargers wer actually draining the battery when plugged in my phone, the very 1st time I plugged in the new cable, man I tell u, I was a happy camper, it actually CHARGED while using my phone, couldn't belive it. But now, 2nd time plugging in the new cable, right back to not even charging. It shows charging and all that but the percentage just goes down. What is going on and can someone please school me right. Thanks.
Now im soo broke, I cant even pay attention!

Are you using the original battery? If so it might be time to get a new one. They are estimated to go downhill after 500 charges. Maybe it just won't hold a charge anymore. I suggest getting the anker 2200mah replacement. It's the same physical size and 10 bucks on Amazon.

[Figured It Out] Between me and my son, we have like 11-12 of those little rectangular boxes that plug into the wall outlet then plug the usb charging cord into those and into the phone to charge, well I switched to a different one with the same new cable I got the other day and WHAM, it actually charges faster than it drains from normal use. Before itd take like 3-4hrs to charge without touching it and drain with 35min of use. Now it charges around a percent every 2 min, and thats even while using it too. The little charging box is the one from my ascend II with my new 12ft charging cable so I can answer the door and check car parts and stuff without having to put my phone down.
Now im soo broke, I cant even pay attention!

I'm glad you got it sorted out. Consider getting that new battery though. Ever since I got a new one I can use my phone for video, GPS, Web browsing, and still have 40 percent battery left by the end of the day. I only charge it when I go to bed. With the original battery I would have to charge it by lunch time. And I just started using the newest paranoid Android rom and I swear it makes my s2 almost as fast as my nexus 5, it amazing.

Ill take that suggestion and give it a shot cause its that time of the year to start working 14hr a day, 7 days a week, till February, and phone charging time and availability will be rare. Thanks.

ROMs or hacks that allow trickle charging past 90%?

So it's already been established that after the EVO charges fully to 100% it then stops receiving a charge and runs off the battery before charge cycling again. All the while displaying 100%.
Has any effort been put into changing the way this operates? Seems like it'd be nice to leave the phone on a charger and when you take it off, it would actually be at 100% and not at some arbitrary percentage between 90% and 100%.
It's better for the battery life.It's really good option if you ask me.

You mean make it so that the battery's status bar shows a realistic value once it stops taking a charge, even though it's still plugged in, right? Not actually changing the way it takes a charge. I'd be interested in seeing that happen.
Is that why when you unplug it, the first 5% or so disappear within minutes?

Yup. This is why when you charge overnight the battery plummets right after.

Don't leave it plugged it after it reaches 100%. Problem solved.

Valid point. Lol
There are some people who don't want to wake up in the middle of the night to unplug their phone. Like me.
annoying, but just unplug your phone when you do wake and plug it back in after about 10 seconds. let it finish fully charging while you get ready.
it's better for the battery though, case closed. Lenovo has been doing somehting similar w/ their laptops for years. It never charges the battery past like 97%, and when it does reach the top it stops charging until it falls below like 92 then recharges. HTC needs to loook out for the battery they already have enough flak from all of us for the last few years w/ every touch device they have had. We want more life, and they are giving it to us, just wish they could figure something out like lenovo, let it go down to mayeb 94 then charge up again perhaps.
it really isn't true, mine dumps 10% or so off the charger regardless of if it has been on the charger all night or 2 seconds after it turns green.
So I've done the:
1 charge to green
2 unplug
3 turn off
4 charge while turned off.....to green again.
And here are my honest results.
Boom........phone has 20% left after 16.5 hrs of moderate use (calling time total 1 hrs talk total, surf /post 1 hour total, load up 5 apps from the market, listen to audio clips on the speaker phone for almost an hour straight, podcast this morning for 30 min...and other randomness)
And still have 20% left. Going since 6:30 a to 10:30 p...........approximately 16 hrs equals 80% so about 3.2 hrs left to use before dead.
THIS EQUALS APPROX 19.2 HOURS OF MODERATE USE BEFORE RECHARGE NEEDED.
eat it Apple 4G . You can't even reliablly make calls let alone last that long without charging. My 3g never lasted that long. You still need a wall Apple we are truly mobile. If I was on the road I could (don't need to just yet) swap out for another battery.
I'm loving xda for all their brains helping me get the most out of this phone. Thanks to all.

The point here is that we shouldn't have to do the "charger circle jerk" to have 100% battery. I should be able to unplug it and have a full battery. Not 90%. I might need that 10% later on today, its accomplishing nothing sitting on my nightstand.
If the battery is toast after a year instead of a year and half, i don't care. I want a fully battery, not an almost full battery.

HTC advised a similar solution to the battery issue. I did this a few times and my battery lasted more than 15 hours with moderate use. Here's the post:

My phone used to do this, even after i followed all the little tips and tricks of playing hide and go seek with the charging cable and my phone.
Know how i solved it?
Bought one of those $10 Ebay 2 1500mAh TP2 Battery And Wall Charger bundles, now i dont use the OEM charger at all, the cable turned into a permanent USB cable on my comp and never sees the actual HTC charging unit it plugs into for AC power. I have 3 batteries and i rotate them in that little wall charger which actually charges them to 100%. Its also proven because if you take one of the batteries, put them in the phone and charge them until the green light comes on, supposedly to "100%" and then take the actual battery out and put it in the ebay wall charger, it will still charge for another 15-25 minutes. Charging it in the phone, as soon as i unplug, it almost instantly always drops to 90%... charging with the ebay wall charger, it will stay at 100% for a while before it falls off.
Below is the link to my thread which contains linkage, pics and info about the ebay bundle, others also claim the same issues and fixes in my thread. I mean for $10 bucks, does it really matter if it works for you or not? Its worth the shot and for me, it was a great investment.
Best of luck.

I did this last night and I'm at 14 hrs and 57% left. If I have to charge like this to get great battery life that's fine. My iPhone 3gs would last half a day. So this is blowing it out of the water. And I can hold it with my left hand to talk.

Good stuff man, I finally just switched batteries after 21 hours.

Cheap eBay extended battery question..

So I just got this battery hm around Wednesday or Thursday, and I have let it die down to around 10% or less and recharged it overnight several times and I still only see a slight difference in battery life. I am (I would say) a moderate user and I know some people say they get around 2 days on heavy use so I wonder what I'm doing wrong..? I ran the SU command to delete the battery.bin file to wipe the stats while it was fully charged, then let it run the whole day again only getting around 12 hrs (probably would have been shorter, but I have juicedefender running, and I was at work for 5 1/2 hrs of those 12) and then I stuck it on the charger at about 7:45 and then around 12 it was fully charged and I of course turned it off, then back on and it said it was around 80% so I let it charged to full, reset it again then when I turned it back on it said it was full. I took it off the charger and within minutes it dropped 1% every minute or 2 and now around 15 minutes later it's at 86% and I'm not even doing anything, just sitting here with the screen on and Skype is running. I've only drained it/fully charged it a few times maybe 3 or 4 should I just keep doing that or did I just get a crappy battery? It's better life than the stock, so I can't help but think that it's not crappy just not fully calibrated or "worn in" yet. Any help would be greatly appreciated!
I too have a cheapo extended battery from eBay, for the first week I hated it, but finally I actually just let the thing completely die to wear the phone shut down and wouldn't turn back on, then I recharged the battery completely in a standalone charger(also ebay), then put it back in the phone and used normally, charging and discharging and now I can't even dream of going back to the OEM battery, my battery life has much more than doubled. I use my phone like most here with CM7 up to date on nightlys and I'm happy as can be. I also like the ext back on the cheapos much better than the seidio flavor.
So you use the wall charger from eBay to charge it? I don't want to take my battery out to charge it though every night, let alone turn it off because I use it as an alarm clock :X. I've read a whole bunch of different ways of how to charge it in your phone and most people even one of the legitimate companies (Seido) who sells it, says that if you let it go an hr or 2 after the light turns green its good to go, but I don't believe it charges after the light turns green hence why the charging icon on the battery goes away. people may "think" it does but I honestly don't think it does and if anybody can prove otherwise I might have to buy the external charger :/
Yes get an external charger, Preferably 2 batteries and 1 external charger.
I just ordered a wall charger for like $15 I hope this works. I'll just charge my extended battery at night and use my other battery when the extended is charging
Sent from my Evo!
I used the external charger just once to "calibrate" the battery it seemed? Since then I've not taken the battery from the phone and just charged it with the phone charger(plugging it in) and I have noticed a huge change in run time.
How do you charge it though now that its calibrated? Do you just leave it on the charger for a few hrs after it hits green or do you have to turn the phone off and back on then stick it on the charger

Well my cheap battery has not blown up with sbc kernels
Yeah, its been about a week and my battery still can't even hold a charge, even if it isn't fully charging. It dies quicker than my stock battery. I told the guy I bought it from, and he said he'd send me a new one so I'm back to the stock battery for now until I get this one next week :/
Hey guys, i know it's a tiny bit off topic, but what about a battery pack??

i have two of those things and they work perfectly. plus, i don't have to kill the phone, open her up and swap batteries. additionally, it'll charge two devices at a time. bonus!
Hmm see that's what I'm trying to get rid of lol having to plug it in all the time. Plus I actually like the bigger back, I personally don't like the thin size of the evo I feel like I could drop it at any time.

How are you guys getting so many hours? I only get like 8 Hours on my heavy use and i bought a 3500mah extended battery wtf? I'm also using the net Netarchy sbc 3.2 more havs and mym rom with setcpu running profiles. What am I doing wrong? I even have juice defender running aswell.
I had my 3500 extended battery and at first it wasnt too good. But after switching to an external charger for all charges and completely letting the battery die out im getting a whole days worth of heavy use with no worries.
No rooting or any battery controls.

[Q] Make primary power source charging cable?

I was wondering if it was possible to have the primary source of power be the USB port versus the battery. I tend to leave my devices plugged in a lot more than I probably should and figured if I could do this it would save on messing up my batteries. It's kind of like having a laptop plugged in without a battery (if you don't really take it out).
Doesn't really help, but if you charge your battery to 100%. you can pull it out as it runs on the usb port from then on. Only worked a few times for me

That's not what I was trying to get at. I was trying to avoid using the battery versus continual draining/charging it. I tend to use it as my hotspot at home for my primary internet connection and sometimes music.
My thought process was if I didn't constantly use the battery I'd keep phone temperature low and not mess up the battery.
Have you ruined batteries in the past by charging them/depleting them? Honestly, I have mine on and off the charger constantly. Today I used my phone to listen to Pandora most of the day and about half way through the day I video chatted with a friend and had it on the charger. I took it off the charger, ran around a little bit away from my house and then came back and it currently sits on the charger again.
From my experience with it, I've never had any issues with keeping it on/off the charger periodically through the day. I am also using a 3500mAh extended battery, but I did the same thing on the stock one.
I understand you are trying to keep temperatures low and play on the safe side, but unless you are noticing unusually high temperatures or something, I wouldn't worry about it being on and off the charger.

Yeah, if you're worried about the battery crapping out, I wouldn't. I've had mine on charger every night or every other night, and it's still like new.
Heck, even if it did die on you, you can get a brand new OEM battery on eBay for less than $6 shipped.
Quick tip on battery. If you go online and sprint chat with a representative, just tell him or her your battery life is no good on your phone. Then he or she will tell you go to buy one then get back on chat and sprint will credit your account. I bought $60 battery extended with case and got credited $60 on my bill
Plus now I can charge one night and last two days!

[Q] Less than 1 hour battery drain, Mytouch 3.5mm

my phone has cyanogenmod 5 installed on it, but it will not charge to 99%, it will charge to roughly 66%, than be completely dead after 30 minutes. I tried using 2-3 different roms, with the same result. I am using a usb cable to charge it, (still waiting on the ac charger), would this have anything to do with it?, or do i need a new battery
My battery died about 18 months after I bought it. Sounds about like what you are experiencing. Take it to a store and borrow a battery and see if it charges. But I would think you just need a new battery.

sorry, I should have followed up on this thread. It turns out, the charger i was using, which was an off-brand charger, was only producing 500ma. i bought an htc mytouch branded charger, and it produces 1000ma, so now it charges just fine and easily lasts throughout the day. thanks for the response though

[Q] Slow fast charge?

Is everyone really getting the 50% charge in 30 mins? It feels like I am getting about 1% per 1 min of charge time on average. Not sure if that is normal or I have a defect somewhere? Also, is fast charging safe to use for every charge session or is it meant to be used once in a while for emergencies? Thank you.
yes my phone will go from zero to 100% in an hour no problem when using charger that came with phone

Really? Did it charge like that from the very beginning or did it take a few charges to get to that speed? I think it takes me like 1.5-2 hrs from real low to full charge with fast charge enabled.

I used to get those insanely fast charge times; however, recently my phone has been charging slower (with fast charging on). Not only that, but, for some reason, the original wall adapter stopped working twice now. The first time it freaked me out because I thought my phone was messed up, but it turned out that everything was working except the adapter. Then later, I found out that if I reboot my phone with the adapter plugged into the wall, the charger will magically start working again! This worked for one or two charges. Today, I found that my phone was, again, charging extremely slow. Not only that, but my phone stopped charging after around 50% and the adapter is broken once more. I've tried the reboot thing three times and it didn't work again T: So now I'm kind of worried my phone might be defective?
Has this happened to anyone else with charging issues?

I haven't ran into anything like that yet. Who is your carrier? Maybe you can take in your charger and battery to get it replaced? Can you try charging with a different quick charging phone or something to narrow down if it's the phone or charger's fault?

Although I am fairly certain that my issue was the wall adapter portion of the charger, I just found it strange that the fast charging function failed to work properly around the same time when my wall adapter started to fail. Hopefully I am right and nothing else was wrong, but I thought that I would say something in-case I was wrong
As for getting it replaced... I bought my Verizon Note 4 at BestBuy off-contract and when I went there, they claimed to not have any in stock. They never really bothered to ask if I wanted to replace it even though I brought all my receipts and junk so I just took that as I wouldn't be getting a replacement haha :crying:
If anything I'll probably end up just buying another fast charger from samsung later, but for now slow charging is fine I guess. The fast charging did make both my device and charger hot, so maybe that was the problem?
edit:
I do not have any other quick charging devices (to my knowledge), but the wall adapter - combined with various other cables - continued to fail with my other phones as well.

Do you know if it's safe to use fast charge for every charge up? If it shortens battery life over time, I'd like to know this now and only use fast charge sparingly.
Yes. It shortens battery life. By using the only charger they give you, you essentially cut your battery life in half. It's a conspiracy by Samsung and the makers of the materials used the batteries

Pretty sure that was sarcasm. I'm less sure about your comment, though. ;P
I read it in American Android, first December issue. They did a study. Only way to avoid the battery dissipation was if you only used the fast charger at night, and Sundays after noon, but before 1pm PST. fascinating article. It's amazing what a group of students at Yale who love Android can actually accomplish.
I think I can work around that charging schedule. I am also going to subscribe to that magazine now.
