I heavily use my infinity with dock. I know that Li-Ion Batteries have degraded battery life every time you let them dissipate to 0%. Unfortunately that almost always happens when I use the dock (Tf201). Is there any way to stop the tablet from charging from the dock around like 5%? I want to keep my dock connected because I want to keep using the keyboard but I don' want to shorten the dock's battery life unnecessarily when my tablet is at 90%.
Is there an app or rom solution to this?

same problem here. my dock drains fast too i feel like its giving it too much power !
Same. Mine charges the tablet super fast, but the dock still works at 0%. I've only gotten it there one though.
Same here, I feel the dock is charging the tablet just a tad too much. When the dock's warning me about 0% battery left, the tablet itself is still at 80-90%. That can be useful if I wanted the dock to ONLY charge the tablet, but when I want to use the dock as well, it's far from ideal.
I'd like it if we had a setting for this, like one for pretty much just using the dock as a spare battery/charger, and one for maximum tablet AND dock battery life. I get that the dock's not much use without the tablet, but it feels unbalanced as it is now.

Same here. I work and every time the dock is 0%. Im at college. Sorry for worse english.
Okay I must be missing something here.. but the dock still works just fine at 0%, why should it keep any power to itself?

Because for Lithium-ion battery it is not good to have it discharged to 0%, this can reduce the battery life span.
Also another problem can be is when battery is a discharged state, its voltage will gradually decrease then the keyboard dock will no longer be charged any further because the protection circuit disables it (Although this usually applies when you are storing the battery at discharged state but its a good idea to keep this in mind).

Actually, the dock battery is not fully depleted when it reaches the nominal zero % charge -- the internal electronics of modern batteries prevent them from depleting to harmful levels. (This has been referenced in the TF700 forums elsewhere, by the way, which a search probably would've shown.)
I think that the charge provided to the main tablet is coming from both the dock battery and the main tablet's battery at the same time; however, since the dock battery has a significantly lower capacity, it should not come as a surprise that it gets 'depleted' sooner.
From a usability or design point of view, I fully agree with you that it would have been nicer to see the dock deplete to about 40% 'resting charge' (which is reputed to be the optimal moment to connect the charger again ) an have the tablet's main kick in. The dock battery could then take over when the main battery reaches 40% charge left. That way we'd have best of both worlds: battery capacity is used optimally, and battery life would be optimal as well.
Alas, this is the real world. From a practical point of view: do not worry you are screwing up your battery, as you're not. Well, of course you are, but all batteries degrade when in use; that's a given -- but when our batteries finally die on us permanently and irreversibly, we'll have at least one other great 64-core 256 GB superduperHD 30" hypertablet available that makes you fresh coffee in the morning, irons your clothes and tells off door salesmen on its own. It will be so heavy it will need legs of its own, but then it also runs all Olympic sprinting distances at least an unbelievable 2.4 seconds faster than the then-current world records.

This ^^ is right, though -- if you wait long enough, even the protection circuitry will fail, and the natural voltage fall-off will kill your battery. If you put away a healthy Li-Ion battery in a fully charged state, this should take about four months at the least, but probably closer to eight months to a year.
I hope someone reads this and decides to create an app that exactly handles this problem. I feel bad when I always discharge to 0%. If this is not so harmful as I feel, I still I dont like it.
I think this is a mental thing for you all. No need for dock to keep a charge. Its designed to push the tablets life longer so you can detach it and keep going if you'd like and not leave any juice behind.

It's not quite as simple as that is it? If it was just an extended battery pack why have a keyboard, USB port and SD card reader included?
Okay, you only see it as an extended battery, not all of us does. Part of the reason why I chose the TF700 is because of the dock. Any portable device can get a portable battery pack to extend battery runtime, this one is a keyboard and port extender as well.
I don't see why we shouldn't be able to further control how the dock depletes its battery, it'd make it a lot more useful overall.

Because you can use all of those when the dock is at 0%. So why do you need to save the docks battery?

Then leave it attached, makes no difference. Add the numbers up to 200%.
If you have 80% battery, what difference does it make if its 0% and 80% or 40% and 40%? (I know battery sizes are different and percentages would be different).
Now overall battery is down to 80%, if you detach tablet with scenario 1, you have max battery left (80%) vs 1/2 of that (40%) if the dock had a charge remaining.
Why should the dock keep any charge? It still works with 0%.

because some of us do not want to let it waste charge when the tablet is already near full. (save some charge for later). we dont want to recharge it just because it gave too much power to the tablet at an uncessary time. i bet alot of people dont want it to charge the tablet to 100% from 99 everytime u turn the screen on lol , it would just make life better with the tablet + dock if we could control when it does charge during sleep ,ect
I'm trying to understand what the problem is here... What good does it do for the dock to keep a charge? You can't use the dock without the tablet and as long as the tablet is connected, the dock will work, even if it reports a 0% charge. So what good would it do to keep, let's say, the dock at a minimum of 10%? That 10% would be completely "wasted", right?
Or am I misunderstanding the issue?

I was under the impression that the dock will eventually "power off" and you won't be able to make use of the keyboard, USB port and SD card reader once its battery is depleted. However, if they're still fully functional as long as the tablet is connected, I don't really mind the current way it's done.
Surely the dock requires some power to operate though, and unless it gets that power from its own battery, the tablet will have to power it. It's this "obfuscation" of actual battery capacity and use I find slightly annoying.
After reading this thread and after some thinking i can dig both camps :laugh:
On one hand, we are concerned about a battery lifespan, and as it is well known that batteries should not deplete to 0%, i can dig those who want to control that. But, there is also a mention that the battery doesn't really go down to 0% and it somehow controls that automatically.
So, no worries on this side.
The other "problem" - which i think is more important, at least to me - is that some of us feel that it is completely unnecessary for the dock to charge the tablet if the later has 99% of battery. I would also like to have some kind of control over this.
Both 100% - i want to use only tablet battery. And i will use it until it drops to about 30-40%. Than i would like the dock to kick in and refill my tablet. Probably right in the middle of my other work when i actually don't use a tablet (faster refill as i am not using it). Well, after it reaches 90%+, please docky dock, get out of the way and wait for your next turn. Maybe i'll refill you, too
So yeah, there is actually NO problem at all, only different use cases. I bet every single one of use has a little bit different usage pattern and with an app to customize these things, we could and should all be happy.
Anyone, anyone? I would like to beta test it

The issue is that Li-ion batteries lose max harge every time they are depleted. You do not want to constantly cycle your battery because of this. The dirty solution is to stop using your dock before this happens but i use my infinity for work and this is not an option.
Sadly after only about a month of use my dock maxes out at only 98% now after being forced to completely dicharge it while working. At this rate, I will lose almost a quarter of the dock's charge in a year. Thats completely unacceptable. For such an expensive device.

Ok i bought this gt n8013 with 4.1.1 and i love it all except for one very horrible thing. It charges so slow its driving me insane. I am sorry if there might be a post about this already but i searched and didnt see any. Is there a way to make it charge faster like buying a faster output charger or something? A setting? I mean wow i could grow old before this thing charges.
How slow is slow? This thing has a pretty big battery so it's going to take a while. From 20% about 5 hours is about normal.
The speed at which it will charge is governed by the device, not the charger, assuming you're using a powerful enough charger. IOW it will take about 2 amps. Even if you try a 5 amp charger, it will still only take 2 amps.
This of course is all assuming that you're using the charger and cable that came with it. That's very important.
Yea im using stock charger. It took around 7 hours to charge and compared to asus that is super slow. Asus tf300 charged in an hour and a half while browsing the web on it. Not that im an asus fanboy cause im not. They really screwed the pooch on that device with the nand and the ram but they got the charging right. Turn it off and its even faster. Now i understand slow charging keeps battery life longer but i honestly would rather pay for a new battery in a year than keep one tetheted to a cord for 2 years.
Is that with or without the dock?

No dock though if it makes it charge faster ill buy one lol. Or whatever would do the trick. I actually use this pretty well all day long about 5 to 6 days a week very very heavy. I use it for everthing. I have a few dell xt3, a dell xps i7 with 3gb gpu, 2 dell desktops and a host of other laptops ect, but the new tablets have moved into a zone that is powerful enough for me to bother with now. They, with the usb adapter and external drives ect have changed the way i do business. At any rate i in general use a tablet about 9-15 hours a day so charging as you can imagine is important. I would like very much to make this my go to device even if i have to figure out how to purchace a second battery and configure some sort of charging dock or external battery or in the best case scenario make it charge fast fast fast lol.
I was actually asking if you had the dock for the TF300.

Yea i had the dock with tf300. It actually took a few hours to charge it seperate. Took longer than the tablet itself, go figure.
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.

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.
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.

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.

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.

Good to see that we're getting a new user who actually does their homework. :thumbup:

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.

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.

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!
So for the s7 edge I opted to get the mophie battery case because neither was water resistant and the mophie charged faster and gave more protection. With the Note 7 the mophie one isnt out yet, but the samsung one does have water resistance now. With 3100 mah i think itll be enough to get some good screen on time. It does come halfway charged so i recommend charging it before use. It works as simple as putting it on and turning it on.
I purchased this on amazon with prime shipping because the samsung website is so backed up they couldnt even give me a date when they might send it.
First up is the packaging. Its nothing special just the normal samsung packaging we've grown accustomed to.

Bottom view (doesnt cover usb type c port)
Overall this will do its job but dont expect very much protection as the front is totally exposed. The charging is very slow. It does make the phone both heavier and thicker as is to be expected and makes 1 handed use harder but its a phablet so who cares. I do reccomend this case, but it is a tad expensive. On the other hand though you have to pay to play. Let me know what ya'll think. Will you get one?

Sorry for some of the pics looking bad, i think photobucket messed em up. Shots taken on z force
Congrats man... Can you please let us know how does the battery lasts? From what i i know it does say battery is 3100mAh but on the back its also written that usable is a lot less than 3100. Anyhow let us know how much total time you could get without plugging it back in.
Also can you confirm does the backpack charges wirelessly or no.
From what I read this only outputs at 1.0a which is gonna be reaaaally slow compared to the standard 2.0a or fast charge. Does it show any specs on the box anywhere?
The backpack itself does not charge wirelessly, only charges the phone wirelessly.

It is slow, but the way i look at it is, does it need to be super fast if its on your phone like all day?
About 3 hrs to full from 16 percent.. idk if it would even make it to full if you are using it but there you go.

I had this for one day and took it back for the Samsung fast charge power brick. The case made the phone very warm and just slowed the drain of the phones battery while in use.

This is exactly what I was going to ask, if I'm out using data, gps, running apps will it even charge....
Thanks!

Yeah at one point I was just cruising Facebook and I kept getting notifications about the device charging too slow. And this was while on wifi with the display at about 50%
Alright, so update. The charger doesnt charge fast we all get that. But it does work well enough that i started today at 500am and it is now 624pm with what i would consider pretty heavy usage. Probably a good 5 hrs screen on time and my phone is at 61 percent with the charger totally depleted, i started the charger at about 80 percent battery. I didnt browse the internet too much i was playing a game called dokkan battles pretty much the whole time with screen at about 25 percent brightness because the room i work in is dark. Just some figures for you guys i will keep updating as info is necessary.
As far as the power bricks go they are nice. And significantly faster, but i like not having to carry them around or plug them in, just one button and im charging.
I think for less than half the price with more capacity and 1.8a output, I would rather have this. It isn't waterproof and no access to spen though.

That could be legit
the samsung backpack charges the phone from 0 to roughly 40% - just tested it with my completely drained note 7 - charging....did not use while charging......turned phone on - battery level was 41% on the phone for about 30 seconds, then dropped to 40%.....
backpack was completely drained at the end of this.
i agree with the OP that it is MUCH easier to have this on the back of the phone rather than lugging around a power bank and cord. however, the backpack battery case is really expensive given the mAH it provides.....
i bought two of them b/c i'm on the phone all day talking to clients from my car.....my two cents is that the cost is worth the convenience, but most others will likely disagree......
cheers.

I'm just curious, if you're in your car, why can't you just get a fast charger for your car and charge it while you're in the car?

Cords
Cords.....hate having to plug snd unplug. Also in in and out of my car all day. This way I have one backpack on my phone while the other one is connected to my fast charger in my car....
My Samsung backpack charger took the phone from 20% to full with 1 dot left. I changed wireless charging settings to slow charge only. Used it a few times while charging for light stuff. Gets a little warm while charging. I'm pretty happy with it. No cables and has pass through charging if you need it. Makes it twice as heavy though. I recommend it.
