Battery drain while charging - AT&T Samsung Galaxy S II Skyrocket SGH-I727

I'm currently running Sean's latest leak/update and have noticed significant battery drain despite being plugged into the charger. I never really paid enough attention while on gb roms, so I'm not sure if this is an ics thing or not. My buddy at work has had similar issues and is completely bone stock, so I'm thinking it's just a skyrocket issue.
Anybody else notice this? It happens no matter what I'm doing on the phone and is obviously more noticeable when playing games. It seems to me that the charger should at least compensate for the usage!
It had me so baffled, I've re-flashed multiple times now with the same results.

Yeah... it's 5v/1a. Same with my buddy. I thought that might be the problem, and I had switched it with an old one, but don't think so. I've used the powerskin in the past, and it's also 5v/1a... still drains with it.
I'm totally puzzled! I've changed chargers, gone with/without the powerskin, re-flashed roms, calibrated the battery and who knows what else. Only thing I hadn't done was replace the battery, but now that my buddy is having issues on stock, I don't know if that's the problem or not....

Its probably the battery while charging check if in about phone it says its conncted to ac.
Also are you rooted?

Could also be the cable. I have had the exact issue, replaced the cable and now its fine. Its funny cause the galaxy s2 is far more picky when it comes to chargers/cables. For instance. I can plug it in and the phone won't do a think, yet when I plug it in the skyrocket it will accept the connection.

I'm thinking it's the battery... it shows it's charging. I've tried spare chargers and cable combos with the same outcome. It's just odd that my friend's is doing the same thing!

I've tried diff cable/charger combos... no luck. I had cable issues with my epic (sprint) and knew Samsung had issues with them in the past, so that was one of the first things that came to mind... no dice though!

Test your receptacle with a digital multi meter . The stock charger works great. Enough so
That i spliced 3 high quality usb cable and have over a ten foot cable which charges just fine.
So its possible. U have a bad charger. Crap cables. Or overdrawn circuit whith your receptacles. No enough to trip but enough your charger cant pull 1 amp

I did a 1.5 hour Skype video while on charge and my battery never charged it held at the same percentage. Anything else I do charging outweighs my use. Gotta be the charger or the phone itself. Even if you have no battery in it should still boot off the charger and run correct?

Use any type of root explorer, while charging got to sys/class/power supply/battery
and open batt_current_xxx or something like this, I'll check it later if you get into troubles, breaking my head now with tasker at the moment. It should show a value around 8500, at least that's what it shows for me.

I'm having the same issue on Sean's latest update, my battery current adc file says 2934... I posted this in the sky ics thread
"I've been having some battery issues since coming to this ROM on update six. I'm on nine now and all is well, battery life included once I get it charged up. I'm using OEM Samsung everything, charging block, two different cables, my original battery and a 2100Mah extended for the Gnex. All Samsung, no change between them. This thing just REFUSES to charge if I'm using it while plugged in, and if I leave it alone and let it charge, it takes absolutely forever to charge either battery. The skyrocket battery won't gain one percent charge if I'm using it while plugged in, and the Gnex battery actually discharges slowly!  Any ideas? I bought this phone from a member on here and it came with superlite 5 and I don't recall it having this problem."

If the file reading is that low there must be an issue with the amp, if you tried a different charger and cables and it happened since changing roms I'd say its a pure software issue. Maybe you should try flashing a different kernel before trying to change your rom, the problem may be laying there.

I had the same issue but mine was related to the usb cable. With a new micro usb cable my phone charges without issue.

Killed my Infuse...

Well I think my Infuse is now a goner.
Initially had charging problems, brought it into ATT and they noted corrosion and blamed it on me, warranty voided and I was SOL.
Purchased a replacement charging port and found out that the damn thing is soldered on. Well I attempted it and accidentally lifted the solder pads.
wanna sell it? or you can try to do the touchstone mod. i pulled mine apart to see how hard it would be to do and it doesnt look to difficult. i would've done it to mine but my infuse is only a couple weeks old. just google touchstone mod if you havent heard of it. but you wont be able to send data you can only use it to charge it wirelessly.
Poor you
I bought an extra pair of batteries along with a will charger, I haven't used the charging port in months. Something you might want to consider.

On Ebay battery charger plus 2 1900 mah batteries for $15ish, which 1900mah is supposed to last longer than stock something you may want to look into, also if you do get your charger port working again then you can charge one via the battery dock and charge the one that's in your phone at the same time (it has USB port on bottom of battery dock) a also its smart charging so it doesn't ruin the battery if you leave it on there all the time

They're 1900mAh batteries, lasts me 19 hours on average. I'm sure it's more of a hassle to have your phone plugged into a wall than it is to leave a battery in the wall.

Im not really sure why, but on my old infuse my phobe wouldnt charge anymore so if charge my batterys off my dads infuse. And i was for sure it was a hardware problem. Then wen my dad upgraded phones a month later he give me his old and i was going to return my old infuse back to ebay. But somehow i fixed it b4 we returned it. Iv tryed changing roms and whiped that phone like no other then randomly after i factory reset on a custum rom it fixed it self.. idk how it fixed it self but it happend. So its possible its a software issue
Not a hassle at all. I rotate between 3 batteries, I haven't plugged my phone in in over two months... I don't see that as a hassle. All I do is power down my phone once a day to swap batteries, nothing like going from 5% to 100% in a battery of minutes. I use to stress about battery life, but that hasn't been an issue since. Its probably become what I brag most about to iphone users.

What about us users that have a nice protective case on it? I use a casemate that has 2 layers of protection, and would be a pain in the butt to remove everyday. And if you use an Otterbox case, those things are damn near impossible to get off without a struggle.
Obviously if you lock up your phone like Fort Knox then this method is not for you. I have a case mate case and I have no issue taking it off once a day, far less troubling than keeping it plugged in hours everyday whilst trying to use it.

I'm not worried about it. I have a car charger if I need to charge while out. I'll be damned if I'm going to open my case every day. If it floats your boat, go for it.

Extreme Overheating while (wireless) charging -- 3 batteries

Hello,
I recently purchased a wireless charging station/pad, the Verizon-branded LG WCP-700. I have 3 different batteries for my Thunderbolt (rooted, stock). 2 of them are the stock/original 1400mA batteries from HTC. One came with the phone, the other was purchased additionally from Verizon. The third is the red MyTouch 1650mA battery, purchased from Verizon.
ALL THREE batteries get warm/hot when charging with a corded charger. Still, it charges fine.
When I use my new wireless WCP-700 charging pad, the phone gets VERY HOT (52+ cel., 120-130 far.). Sometimes, it gets so hot that the charging stops. But sometimes, it charges throughout the night and fully charges the battery, which is fine. This happens with ALL THREE batteries.
What is wrong and what can be done?
Not interested in installing a new kernel, etc.
Not running many background apps.

I've heard, but don't know for certain, that tethering while charging can cause overheating and damage.

Yes. But wired charging works fine (even when tethering).
(btw, is there a better app to use than Wireless Tether? I like it, but my computer keeps losing connection. I have to stop and restart the app).

If its called "wifi tether for root users" in the marketplace, scroll down to the "more by developer" section and try the other one. It's titled the same thing, but has a green wifi icon.
See if that one works any better for you.
Some phones use one better than the other.

My phone used to get really hot when I tethered while I was charging. It was so hot one day that it shut off and wouldn't come back on until it cooled down. That is the only time that has ever happened.

I have tried two apps:
WiFi Tether for Root Users:
https://play.google.com/store/apps/...tLmdvb2dsZWNvZGUuYW5kcm9pZC53aWZpLnRldGhlciJd
Wireless Tether for Root Users:
https://play.google.com/store/apps/details?id=android.tether&feature=related_apps
Both current versions. (although, oddly, it seems that "Wifi" uses "Wireless"'s service).
Both give me the same overheating results.
Any other options?
In my experience it doesn't matter what tether I use it gets hit. That is just the nature of what is going on. The 4g radio is pulling a lot of data and WiFi is having to broadcast all that. Not to mention the CPU has to process all of that. Sounds like a heat generator to me. Oh and don't forget that you're charging the phone at the same time which also generates heat.

Is it possible to break the battery of my HOXL if I used a nexus 7 charger once?

Hello guys I'm I little worried. Here's the thing, I tried for some days figuring out how to root,unlock bootloader, super CID, etc.. it was with good battery life, but after I did all that, I installed the viperxl (i used it with my older HOXL) and everything ran good. What I have noticed is that my battery drain is so, I mean soooo bad..!
I tried a full wipe but I think it's still the same. My phone its brand new so there is no problem with older owners. I haven't changed the radio (maybe could be that?) I have lost more battery on standby than when using the phone and that didn't happened with my older HOXL
So could be that I messed my battery when I charged the phone with the nexus 7 charger??
Or what could be the problem?? Any suggestions will be good, thanks....

Is the N7 charger more amps than the One X charger? Some folks on here have said that the device will only pull the amps it needs, others have contradicted this. I don't know enough about the topic to comment either way. I use a Motorola charger on my One X every day, since it has a longer cord than the HTC charger and it happens to work better where I have it located on my desk.
I can honestly say I've used my nexus 7 charger a few times with no problems
Sent from my HTC One XL using Tapatalk 2
Its a mental thing. I use my nexus 7 charger at home and my htc one at work and a high output Motorola in the car. My battery life has always been superb. Running latest viper with beastmode evita...
From what I know about charger outputs, it doesnt matter, it depends on the device. It can only pull in its max regardless of the charger. Higher the output in a charger should be better so your phone can pull in its max
There's also other factor that contributes to horrible battery life. Rogue apps, horrible networks that switches back and forth between lte and hspa+ and so on...
The last thing could just be a bad battery. Not common but I'm pretty sure it happens

yep the specifications of amps is the current that the charger can handle, as long as the charger of the n7 can handle the same or more current than the one xl charger it should be ok, many chargers are 1A.
For the OP , i think you should definitively try with another rom, maybe stock to make sure that the problem is not your battery?

Your device isn't going to take in 2A. It's only going to take in what it can. I'm not saying that by using a different charger is not going to harm your device, it's just highly unlikely it will. They only way is to flash back to stock and see if that makes a different.
Also, you mention you had another 1x, is your current one a refurb or replacement? That may have something to do with it as well
The Rom is awesome but there are times when it doesn't work for very small numbers of devices...you're just prob unlucky.

It's not a replacement, I soldy older one to a friend and bought this new one, with WiFi I have noticed that standby and normal usage I have a good battery life, the problem is when I'm on 3g/H, maybe could the radio? Because when I'm on data it drains really really fast, like 3-6% per hour on standby...

It might be your radio switching back and forth that's draining your battery.
I have 2 jobs, my first one has lte coverage but not so great in the building so it's always switching from LTE to 4g which I notice drains my battery. My 2nd job at night has great coverage in and out the warehouse. I get full bars of LTE there and my battery would drain very slowly.
In the beginning, I was worried as well because my battery drain seem like a lot so I thought something was wrong but then I checked the battery at my second job and it was great so I figured it was just the network and location.
Overall, especially compared to all the androids I ever used, the one x battery is pretty damn impressive especially for an LTE device.
I came from Verizon using the droid razr and galaxy nexus which couldn't make it past 4 hours on lte with light usage

I've experienced crapp battery life after using my HP Touchpad charger.
Also, my 2nd HOX had horrible battery life out of the box. After fully draining > charging twice my screen on time went from 2.5 hours to 4+ hours with the exact same settings and usage.
Edit: while we're talking batteries... I heard a tech from.the ATT Device Service Center tell two people not to charge their phones overnight because leaving it on the charger when it's full is bad for the battery. Those guys are so smart! They must get their info from Yahoo Answers.

The battery meter calibration gets wiped whenever you flash a custom ROM. You should do at least 2-3 power cycles before making any judgements on battery. Charge to full, but only drain to 10-20%. Draining to shutoff doesn't make it any more accurate, but has the added risk that once in a while the safety circuit will not engage properly, and you will be stuck with a battery that will not accept a charge.
Also, on any ROM but stock AT&T, you can toggle LTE off. Since you don't have LTE in your area, toggle it off (if you haven't already) in Settings>Mobile network settings>network mode.

That's the explanation I've read previously.
But if so, why did HTC used a different charger plug for the HTC Flyer tablet than all their phones? The charge port is an interesting one, in that its bigger than a MicroUSB port, but will still accept a MicroUSB charge or sync cable (the plug only takes up the bottom "half" of the port when plugged in). The pins needed for data sync are the same, and in fact you can actually plug any MicroUSB sync cable or charger into the Flyer. But you can't plug the Flyer's charger (1.62 Amp) to any HTC phone, only the Flyer (and I assume the Jetstream tablet).
Many have said that this is so people would not plug the Flyer charger to a phone, and damage the phone from the higher amps.
Seems like the difference in amps is the only reason HTC used a different charge port for the Flyer.

In my experience, an uncalibrated battery can go from 8% battery to 0% in a matter of minutes. The only way that I've corrected this is with a full discharge.

You're just calibrating the meter, not the battery. The notion of calibrating the battery is left over from 80s technology NiCad batteries.
Under the best of circumstances, the battery meter is nowhere near accurate enough to expect readings less than 8% to be accurate. If you've experienced some more "accurate" reading at this granularity, it may just be placebo or pure chance. Even if true, I'd rather have a bit of inaccuracy in the low end, rather than play with the probability of a battery that won't take a charge.
In any case, you shouldn't be running your battery down that low. We all do it once in a while, but it shouldn't be habit.

The battery usage data is wiped with each boot or charge (same as wiping battery stats). But I don't think that is the same as the calibration data.

Here's the thing, I tried for some days figuring out how to root,unlock bootloader, super CID, etc.. it was with good battery life, but after I did all that, I installed the viperxl (i used it with my older HOXL) and everything ran good. What I have noticed is that my battery drain is so, I mean soooo bad..!
I tried a full wipe but I think it's still the same. My phone its brand new so there is no problem with older owners. I haven't changed the radio (maybe could be that?) I have lost more battery on standby than when using the phone and that didn't happened with my older HOXL
So could be that I messed my battery when I charged the phone with the nexus 7 charger??
Or what could be the problem?? Any suggestions will be good, thanks....

[Q] Honestly, is the Skyrocket a "good" phone?

So here is the deal... I have been a Verizon customer for years, and I am just sick and tired of them jerking me around and upping their rates, taking away unlimited data, taking away early upgrades, etc. So I am thinking of jumping ship and going to Net10. I am currently using the HTC Rezound which seems to be roughly roughly equivalent to the Skyrocket (Yes, I know I will not get true 4G/LTE on Net10, only HSPA+). I can get a new, sealed in the box Galaxy S2 Skyrocket (SGH-i727) for about $210 on eBay.
So where I am going with this, knowing Samsung has had quality models and, well, lets just say questionable models, how is the Skyrocket? Is it solid and relatively problem free? How is battery life, is it easy to unlock, root, ROM, return to stock, etc? Has anyone used this on Net10/StraightTalk?
So basically I am just looking for people's opinion of the phone in general, from a heavy phone users perspective... My other alternative's at this time are a new unlocked HTC Vivid which I can get new for just under $200, or just suck it up and grab a Nexus 4 from Google, although the $350+tax and shipping for the 16GB model would hurt, a lot, right now.
Thoughts?
I, along with most other power users here in the skyrocket forum will tell you that this is a great device. Rooting, rom-ing, and general modifications are a breeze as long as you read the stickies and have an ounce of common sense. Battery life is subjective to individual use, but I generally get around 12-15 hours with 3-5 hours screen on time. This can be extended significantly with a nexus extended battery and a minor modification (see accessories section for details). Hardware wise it it solid. The only common issue we've really seen is the power button failing for some users, I've had mine since it was released though with no issue so far. We have official support for CM, Slim Bean, PACMAN, and Avatar ROM (maybe more but I can't remember off hand), and ports or unofficial builds of just about everything else you'd want. Also, 4.3 is being worked on hard by our fine devs, and it seems that external speaker audio is the only thing preventing a beta release for most roms at the moment.
The community is, for the most part, knowledgeable and willing to assist with any problems you have as long as you attempted to do your homework first.
Any other questions, let me know. Otherwise, I'll extend a tentative welcome to the Skyrocket family.

Thanks for the info!!! I really appreciate it!!!
One more quick question, does the Skyrocket use a standard sized SIM, or one of the newer micro-SIMs?

One issue bothers me a lot. I cannot use the phone for navigation for more than 2 hours even with car charger connected. In about 2 hours, it drains out fully. My latest theory is that after about 30 mins of charging, the battery starts heating up, and so it stops charging.

User error or bad unit I have zero issues with my GPS or car charging. Also what amperage is your car charger capable of outputting.

I am not 100% sure in terms of the amperage. But I tried with a car charger capable of charging a laptop, using the wall charger and cable which came with the phone. I was sitting in the passenger seat, phone was in my lap (not mounted in windshield) and Google Maps was running in navigation mode. For the first 15 minutes or so, I saw that the phone was charging. The charge level increased by 1% or 2%. After I think 20 minutes, it stopped charging. CPU-Z app was showing battery status as
health: over heated or heated (don't remember clearly the text)
power source: connected
status: not charging or discharing
Phone's back was very hot. I unplugged the USB cable and connected it back, and it started charging again! I waited for it to cool down, removed the phone case, repeated this and got the same result.
This is why I believe the phone is doing something to protect it from over heating. I am not sure though.
Well, I placed my order and should have my Skyrocket by the end of the week, and already have my Net10 SIM and $50 Unlimited card! So basically I am saying you will see more of me around here in the future. Thanks again bps119!

Amperage is important son too little it will discharge, I think it will limit if too much. Nav can cause some heat for some of these guys but I've never heard of it getting that high my guess is something was wrong.

I have gotten my last few chargers at Sam's Club, they are about $10, and are rated at [email protected]
In an older phone I had a similar issue where my phone would overheat and not charge properly, once I got a new charger I cut the end off the old one and read the voltage with a meter, it was putting out almost 7.1v (should be 4.75-5.25vDC for USB 1.0-2.0 standard, and 5.25-5.75vDC for USB 3.0), pretty sure that is what caused it... cheap components equals cheap quality and flaws. Current rating should be irrelevant, as long as it meets the devices minimum requirements (most modern phones are [email protected]), even if a charger is rated at 2, 3, or even 5 amps, the device should not draw more than it can handle. Current is drawn, not pushed, a device will draw the needed current at the expected voltage, you can't really "over-current" a device by using a power source that is rated at the proper voltage but a higher current. Similar instance can occur by using a charger that has too low of a current rating, the device will try to draw more current than the adapter is rated at and the adapter will eventually fail or fall out of specifications.
Some other good chargers are by Anker, PowerGen, or RAVPower, and of course a Samsung branded adapter will work well, most all of these can be purchased for $8-$15 on Amazon. If the adapter is not rated with a current rating, then skip it, it is probably only 600ma-750ma and will be more headache than it's worth in the long run.

Just like to say great. I love my skyrocket. Over clocked at 1.78ghz and 320mhz gpu . great performance. Also with nexus extended battery for $6.50 at sprint. I have no reason to buy another phone. Welcome to the skyrocket community.

I have an HTC Sensation and today I rooted my friend's Skyrocket. I must say, EVERYTHING about the Skyrocket amazed me in terms of performance, ease of use, and quality even though it's very similar in hardware specs to my own phone (both are MSM8x60). Rooting the phone only took about 3 minutes (installed TWRP; there was no locked-bootloader crap to deal with) and the colors on the touchscreen are wonderful, not to mention the sensitivity of the screen is great as well. The Skyrocket has official CM10.1 going for it so I installed that and it's fantastic; everything runs perfectly. Even while using the kernel included in CM10.1 the device was very fast but when I overclocked it, the performance blew me away, not to mention the phone didn't heat up at all (even while gaming!); compared to that, my HTC hits 70°C while gaming on CM10.1 at stock CPU/GPU frequencies. Rooting my friend's Skyrocket today has thoroughly convinced me to never buy an HTC again Also, the Skyrocket has great dev support seeing as how CM10.1 is official for it.
TL;DR: The Skyrocket is way better than your HTC and, in terms of development, it's not gonna die any time soon.

The Skyrocket (and several other Samsung phones) need special "type 2" chargers. Apple charges are type 6, so if it says compatible with Apple, don't use it as it may not work. If the two center pins on the USB port doesn't have a 50 ohm resistor across them (or not shorted) , the Skyrocket will only draw 350 mA. Samsung and older Curve BlackBerry chargers have the resistor. At 350 mA, the phone draws more than the charger is providing, and the charger circuitry heats up trying to keep up with demand.
Jrockttu has a great thread under General called "Fix your Skyrockets battery life"
I've MOD'd all of my chargers, now my phone is happy with the screen on all day while driving and it stays charged, or charges slowly...

I recently got rid of my Skyrocket. It was a good device, but a bad phone. The built-in microphone is terrible, people were always screaming that they couldn't hear me unless I used a headset. The signal was poor too, and I would often not receive calls (with no missed call notification or anything).
The Cyanogenmod support is good, and for an old device it runs plenty smooth and plays all the games I throw at it. So it's not bad in that regard. But the actual phone functionality was a real problem for me.

Well, my Skyrocket arrived, looked great and appeared to be "new"... I fired it up and everything looked fine, but it wouldn't recognize the SIM card, just said "NO SIM INSTALLED - EMERGENCY CALLING ONLY" and wouldn't let me do anything in mobile networks at all (said something about must be registered to a network first), so I popped in an actual AT&T SIM, same result, and both SIM cards work in my old HTC Aria. Called the guy I bought it from on eBay, have to send it back and he will send me another new one. Hope this isn't a bad omen.
That sucks man, kinda takes the excitement out of getting the new phone. Oh well, forget it ever happened and hope that it was just a fluke.

Honestly, you'll love the skyrocket. I've had mine for a little over a year and a half and it's more up-to-date than my girlfriend's s3. It's faster and lasts longer on battery as well. Although her s3 isn't rooted, being a newer device, you would think it would work better than mine. Not the case!
If you're trying to unlock your phone, there is an unlocking thread you could check out, although I'm not on touchwiz so I couldn't do it, others have had success with it so you shouldn't have to worry there. We're a great community, just like we've been when I first rooted a year and a half ago. Enjoy!

Charger issue?

After v charging my phone and unplugging the charger it makes a buzzing noise as if there's still electricity running through it. Is this normal? My phone charges fine but I wanted to make sure the charger was safe and not an issue. My battery seems like it goes down fast too though I might be imagining it because I think the b first 2 days it was great and lasted me all day after a full charge.

Nothing to worry about. This topic was brought up in an old Nexus 4 thread and the overall consensus was that it wasn't a big deal. My N4 charger did the same thing. If I never randomly saw that thread. I probably never would have put my ear up to the charger to discover such a thing. I'll have to seashell this new one and see or listen rather to what happens.
The charger is a tansfomer so it will buzz naturally

Unplug the charger from the wall to avoid wasting power. It's in the manual.
