Recently I've realised my phone is always loosing power when I'm using any GPS software while driving. If no GPS software is running - phone charging.
It used to charge OK..
Has anyone else had this issue ?
You need a better car charger. At least 1.0Amps out. 0.5Amps ones can't charge the phone while the screen si on.

Power Hog.
The issue is that the Charger doesn't provide enough power to charge the phone. Whilst your phone is using Google maps it is actually Downloading the map tiles, using GPS to find your location and using both the CPU and GPU heavily to provide turn by turn directions, the phone is using more power than the charger is giving it. Although it will be discharging slower with the charger connected as it is still providing a certain amount of power. I must say that it DOESN'T damage your phone as others argue so.
You need to upgrade the charger, perhaps 2A for fast charging (iPad Chargers)
Hope this helps,

Charging while in the screen of a car is unlikely to damage the phone but will ruin the battery in hot weather. Li-ion battery hates temperatures over 50 degrees C, best point the AC outlet at the phone or just let it discharge.
Also, the phone will stop charging the battery over a certain temperature -which may answer the original question.

unplugged my phone at 8 read xda forum for 5 mins got to work right now 943 already at 89 percent. Does this seem normal? I been checking better battery stats but don't really understand it. I feel like something is trying to sync. i have fetch off for email and Facebook. anyway to diagnose this on saurom rc4 clean boot.

Are you overclocked? If you are, which governor are you using? I've posted in the OC kernel thread about an issue where the CPU is running at max frequency the entire time causing a huge battery drain.
I am right now but its showing me deep sleep and 192mhz on demond has a big percentage. Its not running max clocked i know that.

I think I know what the problem is: Your phone is trying to kill itself and save humanity from that terrible font
seems like a bit much but it could be normal.
Once your phone's charge reaches 100% it stops charging to prevent damage to the Lithium-ion battery. I am not sure however when it starts charging again.
Mine charge % dips even when I am using plugged in! Horrible consumption with screen on.
installed only few apps.

Are you using the Samsung OEM home charger? It shouldn't be dipping when using that one. Mine will charge AND increase while using it in the car with GPS running (huge battery drainer) and a driving DVR program (DailyRoads Voyager) and the screen on. All with a car charger and cheater plug that shorts Pin 2&3. That's the secret to getting rapid charge to work. The OEM home charger has those pins shorted internally. If you are trying to charge over USB on your computer then again you need that cheater plug and ensure the USB port can support more than 700 mA. If it's a USB 3.0 port then it should handle that current.
No problems for me on the stock or aftermarket chargers with the screen on.
I have the same problem with my brand new I717 GN. Battery level slowly drops when on charge, even if it's the OEM wall adapter. I've tried my Kindle USB cables as well with about the same results. I noticed the charge is a bit stronger from the wall source, but still can't keep up with even simple web browsing via WiFi. I've installed JuiceDefender as well, and it's helped reduce depletion a bit, but not really enough. This phone would never last me a full day of intermittent use without a power source.
I've read several of these threads and there doesn't really seem to be a solid solution to this other than some GN owners saying they have the problem and some don't...
Someone mentioned a crosswired 'Smart Adapter Compatible with Samsung Galaxy S' on Amazon (I'm too new and can't post the link)... I might try that but maybe I'll return for a new one if some people don't have this battery problem, unless it turns out to be a latest firmware problem..?

I read an article in a journal recently about how smartphones charge their batteries. The article claimed that once the charge has reached 100%, it will stop providing current to the device until it reaches 90%, after which it will then trickle charge to maintain it at about 90%. All the while the battery meter will still show 100% (at least in the case of iPhones), but after you unplug the phone the first 10% will go rather quickly as it approaches the real charge level.
True for our notes? No idea. But with how Lithium batteries work, I wouldn't be surprised.
I haven't gotten my Note to discharge while plugged in with the OEM AC charger. In the car however, running Waze will suck the life out of it even while charging. (My car charger puts out about 150mA less than the OEM AC charger). Oddly enough, running Navigon on battery alone has less discharge than running Waze while plugged in...Which sucks, because while Waze has crappy directions, it has saved me many hours by routing around traffic. But at least the phone still charges while using Navigon and streaming some Pandora.
My RAZR doesn't charge faster even I used with higher current 2.1 amp charger.
Is there anyway to remove that charging current limitation?
Thanks!

Yeah
By charging the battery directly with a charger.
Don't do that, it's dangerous (possibly) and most likely will damage the battery by charging it too fast.
And higher amperage does charge my razr faster up to ~95%
After that it charges slower, by the time it's at 100 it's like only 10mins
But from 0-90 its about a 30min gain

I know it may sound good to remove he restriction, but it's not a good idea at all.
It's hardware related (probably just some diodes/CIs) and that's the way it should stay (from safety reasons). Batteries have predetermined "life-cycles" and by charging them with a higher current than specified, will definitely cause cells to overheat and melt/ignite. Even if you pull this off once or twice, the battery will die very quickly...

an iphone charger (1A)...it gets insanely hot when charging the razr and charges mostly faster than the stock charger.
i advise to not use the 2 amp charger too often and just live with the charge times, your battery will last longer that way.
does you 2.1 A charger atleast get from 0-50 faster?
maybe it's just too much of a load so it gets restricted

This morning I charged my RAZR with my 2.1A charger. Yes, you're right, it did charge a bit quicker before 50%. So, I reckon, I shouldn't charge my RAZR with it again.

i'd advise against it as that is a major jump in amps
It really shouldn't make a difference, since the phone should only be pulling what it needs/can handle. Any charger 5v 1a and up should ideally take the same amount of time to charge the battery. Just because the charger can supply a higher current doesn't mean the phone will demand it.

the circuit won't let you instantly harm the battery, but we have no idea what the C rating is on the battery so it could still stress the battery more than is needed, and yes, total charge time is pretty much the same, but it gets to a higher percentage faster, and then hits a major slowdown when the charging circuitry kicks in.
my razr makes the iphone charger i have instantly heat up, no other phone/iphone does this, there is nothing wrong with the phone or charger (it's the charger i use when not home)
I'd say it's completely safe to charge any smartphone with compatible charger. Specialized IC will check voltage, current, temperature (and their delta's)and won't let you harm your battery.
If your phone charges faster from 0-90% its OK!
I've used Nokia chargers (AC-10E and AC-50E- 1.3A), also Samsung, HTC, and lots of USB ports in cars, PC's and others with my HD2, S8500, and now XT910 - it works just fine.
If somebody knows what IC Moto used in XT910, we could check what charging routine is used and estimate max charging current (I think that 2.1A charger is overkill)
EDIT: Power management chip in XT910 is Quallcomm PM8028, but no datasheet is available.
I love my Mega. It is by far the best phone Ive ever had. But, the problems I have with the power usage and management on the device are a total nightmare.
1) The discharging nightmare:
The battery lasts NOTHING. Basically I get about 5 hours of use.. maximum.. no matter what I do.. and I have slimmed down to the ROM to having that NOTHING active.. I literally am left with active 6 services and I monitor CPU usage that is always near zero with NO apps hogging resources. From what I monitor on the device's battery usage, it's clearly always about 90% from the display! And yes, I dim the screen as much as I can of course, but usually not below 1/2way.. I hate screens too dim. However even just on standby with the screen off I still lose about 5% to 8% of battery an hour. Worse, even with the device Powered OFF, I still lose about 20% of battery a day. The ONLY way I have found out to control battery drain completely, is to take the battery out. That's it. Anyone else with similar symptoms and a fix or, is just that the stock battery totally sucks??? Also, any other off brand batteries are any better?.. (not the fat ones rated at much higher amps but that have an extra bulge.. that I don’t want)..
2) The charging nightmare:
This to me is the worse problem. It is bad enough how quickly this device issues battery, bit not nearly as bad as trying to charge efficiently again. I now have tried 3 different chargers/brands (and cables) to try fix the charging problem that is, it takes HOURS and HOURS to charge the battery. I am talking 5 to 6 hours to get it charged and if the screen is on and Im using the device it actually charges NOTHING at all and still keeps discharging (albeit much slower of course)... the fact is that the charging process is so pathetically slow that is less than real-time which means, with the device connected to power supply, the battery STILL drains if I try use it. This is absurd. However, mysteriously enough I have found ONE way that charges the phone super fast.. using a SONY External Power Pack (model CP-F1L) rated at 2200mAh. This is seems crazy because the power output of an external power pack should be much lower than the stock (and other Samsung) USB chargers.. but, it's what works.. the ONLY thing that works. And I have noticed that when connected to a USB Power charger, the Mega's Red LED light turn on faded.. however, when connected to the SONY External Power Pack, is bright red. Clearly more juice going in.. or something like that. Again, anyone else with similar symptoms and a fix the charging time, or, any good recommendation on a extra strong USB power adapter/charger that will make this thing at least charge faster?
Thanks in advance for the input and advice:silly:
Sounds like something is not letting your phone sleep or the battery is defective. Try putting CPU spy on it and let it set for a while. Then check to see if it is getting into deep sleep or if it is even stuck at a certain frequency.
There is an app on the playstore called Galaxy charging. Try it to see what rate it is charging. Though with the rate your phone discharges, the charger may only being supplying an amount just over the drain rate which is why it takes so long to charge.

Yep, something wrong there. I'm stock and this thing won't quit :good:
I would flash the stock rom back into your phone and see how the battery works then as this not normal as mentioned by other members as I am still on the stock rom but rooted only and I have great battery life.
That is were to start by flashing the stock rom and if no change then battery or maybe a hardware problem.
Did you have good battery life before you starting flashing with the phone or did this occur after the stock rom was removed and custom rom with stuff removed to gain performance?

You could try to remove the battery from the phone for about 5 secs and re-install and see it that helps as sometimes if you take the charger off as soon as it is done charging it might not show 100% at times when booting as I leave mine on for a bit longer and it seems to help..even though charge light is green..I leave it longer on.
If your phone is rooted get a app called battery calibrator from the google store as it is free and install it and just before you shut down the phone to charge wipe the battery stats with this app and then shutdown phone and fully charge and then see how the battery works after the battery stats wipe as that can usually help.

Thanks for the tip. Installed the app you recommend, now I understand better. With the stock Samsung USB charger I get 420 readings. With the other 2 chargers I get 500 and 540. However, with the Sony External Power Pack I get 1900!..no wonder it charges super fast with it! My question now is what's up with all the USB chargers I have? I even tried my old Galaxy Tab 7 charger (strongest rated charger I have) and still only feeds 480. This is all so bizarre. So, where to get a super strong charger for the Mega?

Usually when this happens there is something wrong with the USB cable not necessarily the charger. Is the sony cable a USB type cable or a hard wired one? If it is USB type try using it with the other chargers and see what your results are.

Yes indeed I notice the Sony Power Pack cable is short and thick. The Samsung cable is long and thin. I get much higher charging power using the thick short cable. Maybe I need go shop for a proper longer/thicker cable.

I've certainly found the USB cable makes a big difference to the charging speed. I got a couple of 2m cables off Ebay and they're hopelessly slow, but the stock Samsung cable is fast. I just wish it was a bit longer!
I have the same issue
I have the Sprint Mega. Not refurbished and original factory state but I have horrific charge/discharge issues. Right now, my phone just got to 100% charge which I then unplugged the charge cable. Within 5 mins, I went from 100% to 96% and it is losing battery even quicker.
VeEuzUKY: It's been a while but do you still have this phone? Any updates? I should prob invest in a thicker USB cable like you've describe. It has the most charge rate.
I got my mega 6.3 last week. Since then it has said 100% charged... even when charging or dead. So I got a new battery thinking it was the battery but its obviously not and im not sure what it is that could be the problem. Im not sure if its crucial for my phone, if it can be fixed easily and cheaply, or if I need to return my phone to the place I bought it from.

Nope. Thats fine... they have an automatic shutoff mechanism built in to prevent overcharging.
- Fully charging and discharging the Lithium-Ion batteries 3-4 times will allow the battery to reach its maximum rated capacity
- Don't ever leave your phone discharged for long - the batteries do self-discharge and the charge could drop low enough to damage the battery
Not Ultra owner (but tend to buy one in near future) but just to make sure, buy some electric plug with timer built in, so it will turn off after some time..
Hmmm.. i should post a guide on all the stuff I found out... here is some of the most useful
Buying cheap: Save money... but do you?
A charger can have an adverse effect. Often, cheap chargers won’t respond so well to the shutoff mechanism in the phone.
Every cheap charger I tested allowed energy to come through in sporadic bursts, which isn’t good for your battery’s life. For example I bought a $2 micro USB charger and testing the pull inside my device ranged from 500 to 1200 mAh. The official Samsung cable allowed 1000-1200 mAh to be pulled. They both charged in similar times, (1 1/5 hours and 2 hours) however I instantly threw the cheaper USB cable in the bin. The battery should handle this ok... SHOULD.... but the cut off circuit inside your device may not function correctly, which would be tragic!
Test this yourself. Plug your phone into your charger and then into the auxiliary input in your stereo. If the audio becomes fuzzy and distorted, then you can be pretty sure that your phone’s battery might not be enjoying whats happening. Swap that power source out for one with proper insulation, and the audio should be crystal clear.
Calibrate your phone’s battery level indicator about once per month. You can do this by running your device until it dies... (0% battery)
The leave it alone for five hours, before fully charging it. This will enable your device to report the battery correctly.
Hi, I have a strange problem: sometime the phone stop charging (charging led also turn off) at 97%-99%. Disconnecting and reconnecting charger force the phone to charge fully. I'm using original z3 compact charger and cable (the same occurs with provided z5c charger: same 1500 mA model).
Model e5823, v 32.0.A.6.152 , Wind Italy branded model (the device is provided by operator, but with no customization at all...seem to be fully unbranded). Any suggestion?

That's not a problem IMO. Why do you feel a need to charge it to exactly 100%?

Cool. But "forcing" the phone to charge to 100% doesn't sound so good for the battery. It's better for the battery to just charge it to 95% and stop, and even better still if you stop at 90%, imo.

Isn't "forcing". Simply the 1.5 Ah charger seems doesn't provide enough power to fully charge battery in some case.
The Z5c simply doesn't charge with some chargers. For example, my Nissan Qashqai car has a USB plug for that, but the phone will not charge as the electrical current is not sufficient.
