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.

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!

I looked all over eBay and all I see are cases for the international HOX and I really want to be able to have one that works for our phone. I remember mugen mentioning that they would have one out already, but they said that over a month ago. Are companies not making it because HTC's sales in the recent quarter was extremely low compared to the projected numbers? If anybody has found one please let me know I love everything about this phone but I hate lugging around a charger, and I don't always have access or the time to plug it in.
PS I don't want to hear anybody come in and say they get 4 hours of screen time blah blah blah on whatever mods they do. That's great, but 4 hours of screen time equals about 6 hours of total usage which is only half the day for me. I'm a college student and I do a lot on my phone whether it be in class taking notes, or on conference calls.
And I'm not complaining about the phone, just lack of this particular accessory. I believe this is a damn near perfect phone I just want the juice to make it even more perfect!
There's no battery cases that are either good or work for the S4 variant as the pins are placed differently.
There are however external battery packs that are relatively small and provide a punch. Had one for the Sammy Vibrant and was super easy to hide in back pack, as you are a college student.

Haven't fully tested, but judging by the MaH, I would expect to be able to charge it two or three times over at least.
Actually judging by the mah I'd say it would charge it around 4 times.
10,000/1,800 is a little more than 5 so its safe to assume 4 times over.

These external chargers actually lose quite a bit of power in translation... I think I remember reading it's a 35% loss but don't remember exactly, so that 10000 mah is really more like 6500 for the phone (somewhere along those lines, anyways).

I really hope a better looking one comes out the options are either cheap looking or incompatible from the moved pins
First of all I want to let everyone know that I love this tablet. Its fast and performs multitasking like a champ. It has even revitalized the artistic side in me. Unfortunately I will have to visit BB to exchange it back to the Infinity. The battery is starting to upset me. It's taking me 5 to 6 hours from 20% to full charge if I leave it alone. Longer if I'm using it while charging and the thing that drove me to my decision was that while I was play mC3 it was actually draining! I was planning on keeping the Note but since I noticed this issue with gameplay, it will not work for me. I never had that issue with the Infinity. The things I've Attempted ... Discharged twice as suggested to maybe help with slow charging but it did not make any difference. I tried different cables and chargers and still no difference. Unless there is something wrong with my tablet I will have to part ways with it. It sickens me.
Can someone try playing a high end game for at least 10mins to see if it is happening to you? If your rooted will you try playing MC3 for 10mins. That's where I first noticed the issue I'm having. I'm hoping that its just my tablet that's defective and I can just exchange it.
Please make sure your plugged in and your device is charging. Thank you!

It bums me out though because the Infinity doesnt have this problem it still charges in 3 hours while playing games. The Note charges at about 4mV which I guess is why it takes longer to charge vs the Infinity's 7 to 8mV and is able to keep the juices flowing even while using battery hogging apps like games. I don't mind waiting 5 to 6 hours but when I want to continue playing my games and the battery is low, I would like it to charge my device as well.

You kind of implied this but you weren't clear: did you try using the supplied wall charger plug?
The charger supplied with the Note should supply a much higher current than standard mobile chargers that also supply charge via a USB port. The tablet itself detects whether the charger is a high current one, and charges at a slow rate if it determines that it isn't.
With the note off, it should have charged from empty in 3 to 4 hours. With it on, obviously it'll be longer. It shouldn't go backwards while being charged, as that would imply it's draining more than the charger is suppling, which is about 10 Watts. See this page for more information (the Tab 10.1 charger is the same as the Note 10.1 charger).

Edit: Yes I used the charger that came with the tablet. My wifes OGT 10.1 and a generic charger. They all have pretty much the same output of 4mV. I have cooltool installed and battery monitor pro to monitor the voltage. All I know is that it does drain whenever its plugged in charging and playing a high intensive game. It takes a very long time for my tablet to charge to 100% from 20% like I mentioned in my first post while in use. I play a lot of games so I need the tablet to charge properly while I play around and its just not doing that. It kept at and around 4mV nothing higher.
Its really awesome that this tablet runs so well and it can take whatever you throw at it. But one thing that is a major deal breaker for me is battery. If it cant charge properly while its in use then it will not suit my needs. Try it out for yourself and let me know if its doing the same for you. The game I play a lot is called Modern Combat 3. Its not compatible for the Note yet but since I have a back up from my SG3 and Infinity I can give you the download link. I guess I'm I the only one that's noticed this? Or is my device truly defective? I guess you guys have already a system setup to where you dont have to charge your tablets until bedtime. I always seem to have to charge it during the afternoon:/
So I ended up returning my Note 10.1 and back to the Infinity. The first night with the Infinity... Bluetooth lag sync:/ noticeable performance issue on JellyBean and available ram went down to as low as 98Mbs after restoring all my Widgets and apps. Then light bleeding on all corners. Then clicking loose screen... Grrrr! Not the same great experience with my previous experience with the Infinity. Though the Infinity has everything I need with all its ports and keyboard with extra battery. I started missing the spen and just the stablility of the Note. So the next day I gave the Noten another go in hopes that the first experience will be better with the battery issue I was experiencing. Very happy that I did! This time around my Note was not draining while I was playing my heavy extensive games and was actually charging it! Though it still takes longer to charge then I would like. I'm now happy.

It's a JiaYu G2. Generally they are very well reviewed. Well, she's had the phone for about 10 days and all of a sudden it stopped charging regularly... It charges extremely slowly. Leaving it overnight for 8 hours charges it only about 30%.
Some of what we tried:
Had her do a power off and battery pull and restart
Charge while turned off
We checked the incoming mA via JiaYu's engineering menu (*#59#) and the incoming mA are fluctuating between 200-450. Is that normal? or should it be a more steady number?
Really really really hoping it's the charger and not the phone. Shipping the phone back and dealing with the Chinese on a customer service issue isn't my idea of a fun couple of weeks.
Ummm... Nobody knows if incoming mA fluctuates?
I have no idea, but have you tried another charger? If the source is really what's fluctuating, it sounds like a charger or other problem.
Maybe the battery is bad. You could try a different one, too. I have no idea if that would cause those symptoms, but you could Google it.

Thanks for your reply. We ordered another charger (from USA) and waiting for it to arrive. Her first language isn't English and she doesn't have transportation, so she's shy to go to an electronics shop.
Another battery would have to be ordered from China. She tested it out with an external charger and it seemed to charge much better than in the phone, but still quite slow... Not enough evidence either way to conclude if it's the battery because it's one of those multi-battery charges where the "pins" can be expanded to accomodate different batteries.... It hasn't been tested with a different battery, so not sure what "normal" charging time is with it.
The phone is only 10 days old...Really hoping it's not the phone... Dealing with Chinese companies on any sort of customer service issue is a nightmare.
What I was hoping was that someone knew about this... Regarding incoming mA from the wall charger... I don't know enough about it... Whether or not fluctuating from 200-500 is normal...
Anyone with a JiaYu G2 could test this out... Or anyone who has "live" mA data read capability through engineering mode or perhaps even "current widget" and can see if it fluctuates...
I'll check that out when I charge tonight if no one else gets back to you. It doesn't sound right to me since my wall charger does a pretty dead-on 2 hour charge at 1000mA, but perhaps it fluctuates and I don't notice (not my area).

Unfortunately, I have discovered that neither my phone or tablet support monitoring incoming current levels.
One thing I thought of is that perhaps the phone is regulating current so that it is "fast" charging at 400mAh and then going down for the final bit. This seems to be an idea I've heard of before. 400mAh is still pretty low for a wall-charger, though - does it fluctuate all the time, or is there a pattern ? What is the charger *supposed* to proivide ?
I'm thinking about how charging from my computer's USB, it charges at a rate of 500mAh - and that will still charge to 100% in less than a night. Even if it was only drawing 200mAh all night, it should still be fully charged, definitely not just 30% (it would have to have an unheard of high capacity for that to make sense).
I don't know a lot about electricity, but I would wonder if the voltage is wrong or something, maybe ?
Hopefully someone who knows more about electricity will see this.

This seems to be an idea I've heard of before. 400mAh is still pretty low for a wall-charger, though - does it fluctuate all the time, or is there a pattern ? What is the charger *supposed* to proivide ?
I'm thinking about how charging from my computer's USB, it charges at a rate of 500mAh - and that will still charge to 100% in less than a night. Even if it was only drawing 200mAh all night, it should still be fully charged, definitely not just 30% (it would have to have an unheard of high capacity for that to make sense).
I don't know a lot about electricity, but I would wonder if the voltage is wrong or something, maybe ?
Hopefully someone who knows more about electricity will see this.

The wall charger is rated for 500mA output... It's within seconds... I don't mean staying steady and then changing at the end.
I really need another battery and a charger. The charger should be arriving within a few days, so we should be to eliminate that as the issue, but if it doesn't fix the issue, still won't know if it's the battery or the phone.
I have a sneaking suspicion it's the phone... but hoping to here some good news here that fluctuating between 250-450 is NOT normal, thus likely the charger... But as you mentioned, even if left at 200 it still should fully charge overnight... Unless the fluctuating is causing the battery to not accept the charge properly... I don't know
What a pain in the ass. I guess there's something to be said for buying local.
Hey people,
I have a quick question that google coudln't solve.
1. what does the information inside the battery compartment mean? (Wattage, rating, etc.)
2. If 2 phones have the same rating and use the same charger, why does one charge significantly faster than the other?
3. |EXTRA CREDIT| Is there anyway to hack a phone/battery to stay powered on beyond the default voltage?
Thanks in advance!!
Bump!! I googled and could not find any information.

1. They're the ratings of the power supply (battery) the phone needs to operate. It needs that voltage to operate and the phone will draw that amount of current.
2. It could be anything from different battery capacities (if you're talking two different phone models, look for mAh on the batteries) to one phone doing more in the background than the other to minor manufacturing variations.
3. I don't understand what you mean by this question. I guess you're talking about how to get more battery life out of the phone? Google should help with that, you're probably just not wording the question properly.
Hope this helps.

3. no .... i want the credit
@vincom @member thanks for the responses. and the 3rd was about the modding a phone/battery/kernel to utilize virtually the whole battery instead of shutting off at the usual voltage rating for the phone model.

Volt and mAh. You're probably talking about mAh.
I can't say I know, but, I think that roms such as CM will usually eat up all of the battery if you let it.
Also it's bad for these kind of batteries to be fully emptied. It decreases their volume so that every time you fully empty this battery it will charge a little bit less energy when recharged. It's better to leave a little bit of energy (like 5%). :good:

Honestly at the rate most people switch phones and being the owner of a phone with a removable battery, As long as I'm getting the longest battery life that all that matter's thanks to companies like anker. also I understand your point though.

I don't get your point.
Do you mean that these phones are just throwaway devices like those red plastic liquor cups so you might as well squeeze all the juice out of it whil you're at it?
I've had my Skyrocket for a year now and I bought it used too. I'm going to keep it until it f**king dies from natural causes.
Not because I have to, but because I realized that I don't need a phone with an ultra HD display, an octa-core CPU and 8 gigs of ram.
It's past ridiculous now, now it's just redundant. The peak of the smartphone as we know it has come an end, see how the difference between the S3 and the S4 is not as big as it was between the S2 and the S3? Same thing with Iphone5 and 5S.
It's because there's no point. We don't need that much power in our phones. We don't even notice the difference in performance.
They have to come up with totally new stuff for the hype to rise again. They're going to drag it out though. Because you know, money.
There are some interesting ideas that are being held back on purpose, like the smartphone-dock that turns it into a PC. Do you see Apple / Samsung selling these docks? Of cource not. Because without it they can sell the same thing twice: as two separate devices.
Or how the software is made in a specifc manner that it makes your phone seem slow.. and it makes you want to buy an new and "better" phone. Really, software nowadays is like there's no such thing as optimization.

I feel you sentiment friend.
I agree hence why I got a GS2 skyrocket. I agree as well the majority of innovation happening in phones is the wrong innovation!
Battery life can get better but it a lot more expensive for the consumer if it doesn't. and YOU'RE RIGHT companies are dragging things out but it's honestly because people are mindlessly buying into the galaxy and apple brand. It's sad for us tech dreamers and for true techies.
with that said I do believe I wanna just squeeze the maximum out of my device, within reason though. I believe the battery is within reason since if a batter ygoes beyong it's voltage it's longevity will be shorter but it's only 10$ for a replacement and that's super cheap IMO.
p.s. the nano technology would be awesome! CES has been a bust a lot of years so far because the big companies aren't really trying like you said anymore :/

It's not that it's sad. It doesn't matter what brand it is, when your goal is to make as much money as possible then that's what you're going to do.
Yeah I know they're really cheap (at least the knockoffs) I even got two spare ones myself.
Actually, I usually use the battery until the phone dies off. I told you that just in case.
Also a battery's capacity is usually measured in milliampere-hour or mAh. Not voltage.
About CES, the big companies are trying very hard indeed, I'm sure thir R&D's are working their butts off. Behind closed doors.
So they can milk this cow for as long as possible.

That charger most likely will cause a wakelock. I've had similiar charges and they all caused wakelocks. Best bet....use the original charger the phone came with.

Just speaking from expierience. I've had alot of similiar chargers..just all of them did cause wakelocks. I can't say this one will for sure...but i'd rather test a proven product than flip a coin. The original charger the Skyrocket comes with works good. A duel usb At&t branded also works good for me.

thanks but the original charger charges super slow! if you read above it takes a really long time for me. also wakelock would be worth faster charging. plus I can remove those easy
I've been an avid follower of Accubattery and keeping my battery from degrading...BUT I'm curious if anyone knows, is this still a thing in 2020 with the N20U?
https://accubattery.zendesk.com/hc/en-us/articles/210224725-Charging-research-and-methodology
They appear to have sound research on it but wondered if anyone else has information about it?
Huh? I've been charging my phones to 100% since 2008. Don't worry about it.
Sent from my SM-N975F using Tapatalk
I think it stands for old batteries and chargers, that charged them at a constant rate while lithium ones are sensitive to heat (at least) and need variable voltage and current depending of their actual charge level or they degrade faster over time.
And that exactly what the Power Delivery standard does which Samsung phones are compliant since the Note 10 if I'm not wrong.
So i wouldn't mind charging to 100%
I've been charging my phones to 100% and leaving them on the charger overnight for years! I've never seen any noticeable degradation of the battery life due to this.

I try not to leave them on the charger all night these days but I did that for years also and no issues either.
Not worth the hassle for me. I've had slight battery degradation if I keep a phone two years, but hardly worth daily struggles. I usually upgrade after a year anyway, haha.

Haha yeah thats a good point...never have one long to even think about battery issues lol
I charge my Note 10+ to 80% and Accubattery shows battery health at 99.95%
I have noticed battery health falling about 8% in one year of use if you always charge to 100%. That being said, I think Samsung has improved batteries a lot and Note10+ onwards use special battery that degrades slower than previous devices
The old 40%-80% was for older technology batteries. Even then it only extended the battery life marginally, and only over many years. it's not like it's a magic cure to make your battery last a significantly long time.
Just charge the phone to 100% whenever you need to, and don't worry about how often yo need to charge it. Battery technology has come so far, and it doesn't matter how often you charge them or how high. There's technology in there to stop charging once it reaches 100% so that it doesn't overcharge.
On the Tab S tablet and under the charging setting there's a protect battery toggle where it will charge the battery to 85%.
I don't know why they don't have this option on their phones but I'm not sure how necessary it really is.

I had great success on my note 9 with the 80 percent charge. Over the long haul it seemed to me to keep getting better. I am doing it now to see how it goes . I also avoid fast charging as much as possible to see if that helps as well. I wasn't aware that they made changes since the note 9 ,so maybe it's all for nothing.

I seem to be on a “how to” kick this AM .... so I understand the debate about 80 vs 100
But how in the heck do you guys actually accomplish only charging to 80%?? I’m so busy I can’t remember to do half the stuff that I really need to remember , let alone remember to take my phone off the charger.
Also do you guys just turn of all 3 of the “fast charging” options in the settings , unless you need them at a particular time?

I used to turn of all fast charging options. I also would find a routine where the time needed to charge matched the time I was doing something without the phone. For me in the morning when getting ready for work was the best time . Had it down to a science, and the alarm from accu battery helps me as well. It does go kinda rough at first, but after a month or so , I did notice that the charges to 80 lasted longer, then it was down to once a day.

Have you guys noticed with wireless charging the phone is still warm after reaching 100 percent.

Did you finally get and does it work well as advertised?
I opened a separate thread some time ago and people advised to use 30-80 range. I also have Accubattery and follow this principle religiously. However, no matter how I do it, the power charge cycle goes up like crazy. My phone is 2 weeks old and the cycle is now 15 whilst it says the average life is 400-500 cycles. I never bothered about this with my previous phones but don't know what to do with this one. I want it to serve for at least 2 years before I upgrade.
