i just got this phone a few days ago. i love it. nothing wrong with it.
super fast and everything. im on 2.3.6. no issues. my battery lasts 12 hours easy. and actually up to 26 hours so far.
i dont even feel the need for a custom rom. at least not for now.
but one thing that makes me mad is how slow the phone charges, anyone know why this is ? it's kinda frustrating lol
any way to change this ?
also....i kinda hate that there is no camera button on the actual phone. oh well.
*Edited*
well i dont like to charge unless my battery is on red. so that conflicts, its not always red when i go to sleep. but thanks i'll check it out.
and i dont want to unlock to camera. it's easier to take photos with a button is what im saying

If I remember correctly waiting till the battery is completely depleted is not a good thing for our batteries.
i never said completely depleted though.
and yea ive read so many reviews to not do that, and reviews that say you should... and reviews to charge it this much and that much and blah blah. may be a new phone, but none of this is new to me.
Charge current is hardware limited from what I've read. Or atleast for the time being. If your using the phone while charging it'll be significantly slower. Also using wallplug makes a difference. If you've got stuff running while charging try throttling down the CPU while charging.
Other than that I think our phone is limited to 650mah to charge. So 1650/650 is about 2.5 hours with perfect efficiency. Now take into account the power being drawn and how the chargers for li batteries work, that's about 3-4 hrs to be expected.
And don't run li batteries all the way down on a regular basis, its not good. I'm not positive on li ion batteries, but with lipo you generally want to use about %80 of rated capacity to prolong life and power of the cell.
400 mA on USB, 650 on a wall charger, CPU/screen usage counts against these limits - no way to change this
Forgot where I read it. Could be wrong too.
Slow charging for this phone was samsungs way of keeping our phones battery in shape. Hopefully prolonging the life of it. I noticed my 3GS lose about 20% of its full capacity in a couple years. Only time will tell?
Siyah has an option to upping the charging mA I believe.

all useful responses and all make sense. thank you guys.
i dont use it when it charges and yea it does take about 4 hours to charge.
coming from a crappy xperia x10 which took about 2 hours to charge from 0 to 100
but this phone is 10 times better even without a custom rom so i can deal.
thank you guys for ur knowledge.

He removed it because it turned out not to work. (If it's still there I'm surprised - it should be completely gone.)
It turns out the I9100 has the same limitation as the I777 - charging is handled not by the MAX8997, but by a MAX8922.

If you are on Entropy's DD kernel you should divide that number by 2.85
Battery charge current monitoring (CurrentWidget) support - only reports charge current and not discharge, and reports a value 2.85 times the actual current. Use CurrentWidget's "operation on value" to divide by 2.85.

This is for kernel devs only. The patch itself is useless to those who do not/can not compile their own kernel.
This was a pretty big hit on some other devices so I figured I'd give it a shot for you gys. This allows one to force AC charging for any charger that is detected as USB (e.g. many car chargers) and pull the full current the charger can support. It also provides additional security when connecting to public charging stations because by forcing AC charging, USB/adb data transfers are disabled, protecting your data.
It is essentially a software version of the modified charge only usb cables.
Fast charge can be toggled by issuing:
echo 1 > /sys/kernel/fast_charge/force_fast_charge
and off:
echo 0 > /sys/kernel/fast_charge/force_fast_charge
In addition I have created a toggle fast charge widget that may be used to toggle fast charge on and off right from your home screen:
https://play.google.com/store/apps/details?id=com.incredicontrol.fastchargewidget
I have also implemented a toggle in IncrediControl (free) that will allow you to turn it on and off.
https://play.google.com/store/apps/details?id=com.incredicontrol
For the widget (or any fast charge toggle) to work, you MUST be running a kernel that has this patch implemented.
As a good gesture to support a fellow dev, I ask that if you implement the patch into your kernel, please link to my widget as one means to toggle it. You are of course free to provide other ways to toggle it as well if you so desire.
Kernel devs, if you would like to test the widget yourself to confirm its working, and for convenience of testing, please contact me and I will provide you with a copy. You must show that you are a kernel dev though (i.e. link me to your kernel post so I can match your username).
Good luck have fun!

Will dual mount SD, or multi mount still work after enabling this

When on, it will be detected as AC for any source normally detected as USB. This includes your computer. Not every computer can put out enough amperage to significantly increase charge speed though. So it depends on your charging source. Even if your charging source can't put out more than 500mA (what USB charging is limited to), since the phone is in AC mode, it will be able to sleep while connected to the USB source so you will see some small gain because of less power usage from the phone.

When you have the feature toggled on, the phone is in AC mode and all USB transfers are disabled. Turning it on and off is as simple as tapping the widget or opening an app and unchecking a box though.
Tap the widget on (or other means of toggling) - AC mode
Tap the widget off - Auto (detects based on charging source like stock)

Fast charge? I remember having that on the DHD, Lord Clockan's work. It was great having that extra overcharge + fast charge...
I'm no dev, but having this feature on future ROMs would be very nice.
-----
Any chance you can max the current input? I mean... it begins at >+900mA when the battery is very low, and the current slows down as the battery charges.
Also, when playing a game that, say, consumes about -400mA and the current input is +800mA, the current will slow down to +400mA only (since another 400mA are being consumed by the phone). You can immagine what happens when the battery is almost full and you're playing a game...
I am guessing that having the current input always maxxed out would charge the battery (a lot) faster. Would that damage it, too? If not, could it be implemented?
in experience, below 80% the numbers are as per below
900+ ma WALL PLUG
400+ ma USB
600+ ma CAR CHARGER
these are rough numbers, not accurate
after 80%, they tend to be slower

I can't press "Install" while Filter Screen / Screen Adjuster is running / turned on. That's the only thing that prevented me from installing apps until now... If you have that installed, I suggest you turn it off for the time you're installing apps.
Otherwise... I don't know... Wipe cache, dalvik, fix permissions, zipalign apks...
Id love to see this implemented.. im running the standard LeeDroId kernel.. id happily flash it over the top if that would be of any help. I do 80% of my phone charging via USB.

I would be concerned with heat buildup and possible damage by pushing that much additional current. Not to say its not possible, but I would be leery of implementing it.

As I thought. Not going to make a fuss about it, it was just an idea; I knew it could be dangerous
I bought a pack that had a car charger and a wall charger (both of supposedly 1A output) - lighter than the battery cap of the EVO 3D, rofl. The car charger worked perfectly (the power output was meeting the expectances). The wall charger barely sends 30mA (ROFL). In the pack, I also got some sort of expandable Apple cable. The entire "pack" was cheap Chinese crap, I paid ~$3 on it.
I still have the oh-so-good wall charger. It didn't push much current to the Desire HD even with the fast charging kernel...
Guess in cases like that, there's nothing any kernel patch would be able to solve, eh?

I just installed that newer version of BMW. Selected HTC Evo (test) as mA retrieval method. Battery is at 90% and the input current is +305mA. Also, I disagree that the phone takes +900mA from the wall charger when the battery is under 80%. Input over 900 is only when the battery is like under 10%... At 50%, for example, it isn't +900...
ive got 3 wall chargers, and all of them are original from the phones I bought respectively, HD2 HD2 and EVO3D
they report about 900 below a certain %, and it could be 40% , 50%, 80%, etc
i guess you get the drift
anyways, you are supposed to select Automatic to get proper drain readings
forgot 2 mention that
Still need a tester to PM me. Have a test kernel ready to go, just need confirmation so I can post the patch.

Hello, guys. I know this post is awfully long, but please, bear with me
I am fairly new to Sammy, as I just got the S2 (I9100, not some other variant... it's the very original) three days ago. I rooted it, flashed CWM, and already tried a few ROMs. I'm sticking to MIUIv4 (WIUI, actually) for the moment, as I loved having MIUI on my previous devices.
There's just one thing that makes me wanna throw rocks at this phone... and that's not the Super AMOLED+ screen that has stains / ghosting effect... it's the CHARGER.
I believe the charger I'm using is original - it was in the package, so... it can't be a copy, lol. It says it can output 700mA at 5V, which is pretty standard... but it seems like it just doesn't do its job!!!
I've had three HTC devices before, and the HTC charger is just a brick that you plug into the socket, and then plug a USB cable in it (just like Motorola's and Apple's recently). It outputs 1A at 5V.
The Motorola ATRIX I previously owned had a charger that was outputting 850mA at 5.1V. Charging that 1900 mAh beast battery would take just a little over 3 hours!
I no longer own the ATRIX (sold it to get the S2, actually), but I did borrow a HTC charger (with a HTC USB cable) to see if I could charge my S2 faster. Nopes. The charger barely gave the S2 0.5 amps... which is normal, since I hear two pins must be connected in order for the Samsung phone to draw maximum power.
My Galaxy S2 is charging painfully slow with this original charger. I installed Battery Monitor Widget and let it log the battery charging overnight - the log file is attached below this post.
At the very first line of that text file, you can see the charging began. I let the phone turned on, with the screen off, to charge overnight. Wi-Fi, Mobile Data, BT, GPS, Auto-sync was off. It was just in auto 2G/3G mode. That hardly matters!
It looks like the phone is drawing 641mA constantly. It doesn't top 700mA, but that's okay - neither did the HTC phones reach more than 900mA, when the charger was able of 1A output.
It took the SGS2 exactly two hours and 50 minutes to fully charge. Given the fact that the charger outputs 700mA, and the battery is 1650mA, I'd say that's right. A 1900mAh battery was completely charged in 3 hours and something, with a 850mA output charger.
Still, that's painfully slow. I had the HTC EVO 3D, which has a 1730mAh battery. Charging that (@1A) would take little over two and a half hours. I could even browse the web via Wi-Fi or do something else on the phone and the battery would still be completely charged in less than three hours (unless I play a game on 3G with max brightness on, of course).
Also, when the battery was at 1% at lunchtime, I plugged in the charger. I continued to send text messages and browse the web via Wi-Fi (screen brightness was on minimum). The battery level did not rise from 1% even after 5 minutes! You can see that in the battery log. Yes, the phone's battery was almost dead in less than three hours.
Oh, also, the first day I got the phone, after I finished rooting and flashing MIUI and everything... I was playing Dark Legends, over Wi-Fi (screen was at lowest, again). Battery got down to 6%, I plug it into the charger. Ten minutes later, battery was down to 2% ! ! ! So, the charger cannot keep up !
I did my homeworks and did a "bit" of Google searching... it turns out the charger is just as it is. But this is just ridiculous.
-----
I remember seeing something on Twitter several months ago... an article regarding an app that would let you adjust how much power the Galaxy S2 can draw from the charger it's connected to, simply by dragging around a slider. I'm not wrong, I DID see such an article - I just can't find it anymore!
Anyone... any suggestions, please?
Also, please note that I am in Europe, Romania, so I can't just go to a shop and find the most awesome charger that outputs 2A for $5 like you guys can (there, in the US)... It's not really at hand for me, lol.
So, conclusion is the phone can consume more amps during usage than the stock charger can supply.
Either reduce the power usage (lower brightness, disable WiFi/BT) when you're using the phone during charging or get a more powerful charger (although I remember the latest stock ICS kernels don't like charging at a higher voltage than the stock charger supplies, so you'll probably have to install a different kernel which doesn't have this limitation).
Oh, and please stop the non-sense about being in Romania and not having options to buy, the market's full of all kinds of chargers. Get out of the house and search, "lol".
This is not uncommon.
In fact, with my PREVIOUS phone, the SE Mini Pro (the original one), it was actually possible to drain the battery till the phone shut down, even on it's original charger.
With some modified power settings, mostly in CPU voltages, it is quite possible to have the SII charge properly even while in use, but bear in mind, it will take longer to charge if you are using it.

Playing Dark Legends, via 3G this time (so the power consumption would be higher, right?), screen at FULL BRIGHTNESS, Bluetooth and GPS activated. Battery Monitor Widget tells me the current being drawn is 641mA. Looks like the phone draws 641mA when charging, ~80% of the time.
The only problem seems to be when the battery level is LOW. Then, no matter what you do, the power level just doesn't rise.
With HTC / Motorola, the power draw was maximum when the battery was at its (almost) lowest level, and would decrease as the battery was filling. With the SGS2, it looks like it draws 640mA from 0% to 70%, THEN it begins to slow down.

Oh, but trust me, I have. You know, in our country, even cheap Chinese copies are over-rated. It's hard to find stuff like what they have in the US .
I've seen some sort of a digital charger, so-to-say, which would allow you to set the amperage and voltage that was being outputted. It was able of throwing out anything from .5 to 2 amps, at 3.7 - 5.5V (given your choice). Guess what : friend got it from the States...
You don't see such stuff here, in Romania.

On the HTC EVO 3D and Motorola ATRIX, it was yet to be proven whether undervolting the CPU would increase battery life or not. Undervolting as much as 200mV only reduced the ammount of heat that was generated (especially during gaming sessions). Although current = heat... the power consumption didn't seem to change a bit!
I even tried to downclock the CPU to 400 MHz - power draw would still not be sufficient in order for the phone to charge (when the battery level was under 10%). Everything was turned off, light on lowest, CPU pretty low... still going down, lol.
I have also experienced this in the past.... which was rather annoying if I must say however, recently I haven't had this issue, although it still charges quite slowly, it's slightly faster than before. I noticed this difference after I decreased the voltage from the cpu in each step, yes my phone is heavy undervolted thanks to magic config, might want to check that out, but it's still as smooth as ever without a hint of lag props to the hyperdroid team...they are the best in my opinion, I use their rom since the hd2 days recommend their rom to all galaxy s2 users.
Anyway, my point is, I can have my screen in full brightness and still use the phone as is when off charge and it will continue to charge. Also, battery life isn't an issue for me anymore after undervolting, I can live with 15 hours battery life under extreme heavy usage with full screen brightness of 4-5 or more hours of screen on time....and that's with 1650mah battery. I plan to get an official 2000mah battery which will increase it's life more

Red pill kernal is well optimised. I use noop scheduler and conservative governor, it's amazing how redpill handles this. Try it some time. Could solve your problem.

Just like your 48x CD burner doesn't write at 48x from start to finish, that's how the charging current is not constant; it depends on the remaining capacity, charging algorithms, etc. You're using a special case and asking too much, the solution has been given already (powerful charger and modified kernel to allow a higher charging current and voltage).

Yeah, I know that. That's exactly what I'm saying. The algorithm is different on the S2, it seems.
On all HTC devices I had, the current draw was at its highest (~900mA) when the battery was near depletion, and as the battery was filling up, the current draw was slowly decreasing. On the S2, it looks like it's the other way around. When the battery is nearly empty (1%), barely 100mA are being drawn. As it fills up, near 10% or so, the current draw remains steady at ~641mA, and decreases only past the 70% point.
Good thing is, the current draw remains steady at 641mA, no matter how much I stress the phone! That's astonishing - the other day, the battery was LEAKING 600mA instead of GETTING 641mA when the simplest tasks were done (no stress, that is), during charging...
Guess the guy who had this phone before me didn't really ever charge up the battery properly He said he had an iPhone charger back at home; I told him "nevermind, keep it".

I'll look for that kernel, hope it's MIUIv4-compatible. Thank you!

Yes you do. I got a 1A Energizer charger which really gives 1A for less than 10$. The variable supply you're describing can be found in any proper electronics shop, try "Maica Domnului" street

Everyone's talking about a specific shop down that street... and I never got to actually go there. Guess I gotta look for it... Was kind of doubting it was much of a big deal.

My phone gets hot like hell when I'm using HERE Drive+ or Waze.
Is it normal?
ps.: posted on the wrong section, sorry.

And what about battery drain after a while?
My Lumia 920 gets too hot and battery drains really fast, about 30%/hour.
Is that normal?

most of the time i used a car charger, so really don't know about the battery drain

It is a little higher than normal, but not exactly abnormal.
Here Drive does smash my phone too, but it's less.. abusive on GDR3.

Nice, I can't wait Microsoft release GDR3!
I'm a person who is a heave GPS user, I need that on my phone without battery drain or phone getting hot
OMG, I've just installed the GDR3 Preview and I must say. GPS improved A LOT! It doesn't make my L920 burn anymore, and the Battery drain is better now.
Actually I use Here Drive also and the battery not only gets hot, but also drains really fast... in fact faster than any charger can charge the phone, so even when it is connected to charger it still drains battery at about 10%~20% per hour. The only cure is to turn off the phone for about 5 min and turn it back on and after a couple of sessions of Here Drive the same thing happens again until you do a cold power cycle again.
I have sent the phone back for service and even complained to Nokia and that did not do anything. In my opinion this seems to be a hardware design flaw with the GPS or the SoC in this phone. I have had this issue ever since I got this phone in Dec 2013. I have the latest available update on it as well.
Battery life is really not a strong point on this phone, and the GPS is not very good at all. Can't rely on the navigation on this phone for a long trip since you will drain your battery, even if it is plugged in to charger.

I have to disagree with your statements ... I have used both HERE Drive and Navigon all day with out the drainage issues that you mention -- in fact, the phone will charge while using the navigation ... BUT, there are some things that I have noticed:
Not all charges are the same ... I had some that were not able to charge the phone while using the navigation.
Not all cars are the same -- I have a charger that works in my Rav4 without problems ... went on a trip and rented a Chevy Cruz, and the same charger was not able to keep the phone from discharging when using the navigation -- and it got hot -- that was not the case with the Rav4. I switched to the USB connection in the Cruz -- and it was better, but did not solve the charging issue, although it did not get as hot when using it -- but it did not seem to be able to increase the charge on the phone.
The phone's GPS works without problems -- locks on, and provides good information -- especially if you are using a nav program that has the maps installed in the phone.

I wasn't very clear about the GPS function on the phone. My complaint is NOT the GPS accuracy and speed, but the fact that using GPS drains the battery while in use and reduces the battery life significantly even after quitting the application until the phone is rebooted. I apologize for not being clear on that.
I had suspected issues with the charger, and I have 6 different car chargers (ranging from 500mA to 2A outputs). I'm on the road all day and I drive different cars (2012 Mitsubishi and 2013 and now a 2014 Ford Fusion). I can verify that some chargers seem to work better than others. But I cannot verify that if the chargers work differently in different cars.
I also have my work laptop running and I have tried connecting the phone to the USB ports on the laptop with the same result. I have also used the original Nokia wall charger connected to 2 different digital inverters (110v AC, one is 150W output and another 400W, two different brands) and same issue.
In fact if I run a game such as Asphalt 8 on the phone while it is connected to the wall charger at home the battery still drains while playing the game (started last night at 95% charge and drained to 65% in 30min while plugged into the wall charger).
I'm pretty sure my issue is not with the chargers
In short, YES that is common behaviour when using GPS such as Here Drive

Perhaps this is regional accessibility of satellites?

I've figured out that this issue it's not a problem of the charger itself.
It's a security system, if the phone gets too hot, the charging stops to avoid some kind of accident, like battery exploding (as we commonly see on Apple products charging with generic chargers). That's why the battery still goes out even if the phone is plugged in the charger.
When you guys be in a car, try to put the phone in a position that the Air Conditioner can blow the cold air in the back of the phone. The battery will last longer, maybe even it won't dry.
I know this is an old topic, but I wanted to mention this.
The phone *will* get hot and it will drain quickly while using GPS. Even if it is plugged in, it could still drain pretty fast if your charger isn't replenishing your charge as quickly as the phone is draining. The ticket is to use a good charger while in the car. I use the one here: http://ebay.to/1ExuLj6 [shortened link], and it keeps the phone in the plus while using GPS. Before that, I used a mediocre adapter and driving to Valencia, CA from Las Vegas, the phone died after 3.5 hours of driving rendering the use of GPS at that point....pointless. So good adapter = solid GPS use. The phone will still heat up though. There is nothing you can do about that unless you have it on ice
I use MHL Adapter with the device or i plug in my PS3 controller during which the battery drains rapidly, thanks to the power hungry Tegra 3.
It would be lovely to be able to power it or charge it at the same time in order to prolong the duration of usage.
Can a split USB cable be used for that purpose? Or is it possible to charge it via the 3.5mm jack?(though i know its funny but ruling it out)
Let me know the possibilities.

never charge this device while heavy cpu/gpu load, it will get too hot!

True that. Too bad that its gaming capabilities cannot be put to more durable and robust use.

Although it's an NVidia SoC this thing was never good for gaming, even when it was just released. The GPU just sucks for newer games and the whole SoC gets way too hot when using all four cores at maximum frequency. If you want something that's good for gaming and has better battery life, you should probably go for something else. Just my opinion though, i stopped playing 3d games when my first battery died, probably because of overheating too much and too often.
Don't get me wrong, i'm quite satisfied with it for my needs and it's still way faster than some newer middle class devices with official kitkat rom, but for gaming it's far away from good. even playing some candy crush saga on this device get's it pretty warm/hot.
