[Q] Battery drain during Navigation

I've noticed since updating to JB, that the battery is draining during Navigation quicker than my 1A car charger than charge it.
Has anyone else noticed this?

Mines draining faster also.. Not good on long trip...

I've had to start turning my data connection off after getting navigation directions, or I'll be out of battery by the time I get where I'm going

If you install a Kernel that enables fast-charge, then your car charger should be able to keep up. At least it does for me.

Doesn't seem to on Franco for me. Is there a way I can see the input charge and discharge rate for the device?

Best way to charge phone

Hello I was wondering what is the optimal way to charge the s3? With wall charger or in comp? Should I let it plugued more after it says "Charged(100%)"?
I have a Zerolemon 7100mAh

I just picked up a Zero Lemon 2300 and still trying to figure out best way. The instructions they give you just dont make sense to me

They make it looks kinda simple but how can we be sure the battery is really fully charged or decharged etc..

Exactly. Plus every time I read someones post on how they did it its always different.
My first battery charge I did what they said. Charged for 12 hours with phone off. Ran it down to 1% and then recharged. Left it on charger for about half hour-hour past full charge. Did the 5 recharge cycles.
Think second battery I may install and run down to 1% before fully charging. My batteries came in with about 56% charge. I dont see why they would need to be charged for 12 hours like that

fastest should always be wall charger since it has higher current than your usb port in your computer will output, especially if you don't have fast charge enabled (root and rom support required for fast charge).
TL;DR use a wall charger

Yeah wall charger charges up the battery faster than in the computer. But I don't mind the time it takes.. The question is which method is better for the battery? Plus I don't use fast charge since opinion on its risk varie a lot.

Chemically speaking, the speed variation of the reaction shouldn't matter on health. The process is pretty much reversible which is why you can recharge it after draining. The only reason batteries die is because this process isn't perfect, and sometimes chemical pollutants form. In this case the current and time variation shouldn't provide a better battery health either way. For best battery health simply drain the whole way down before charging it. Charging it when its not completely empty tends to make it die faster. (Chem major here)

OK here's the reply I got
Rami Mubasher
For best results we ask that customers let the items die down to 1-4% before your first charge. Leave the battery charging for 12 hours if you are able to. Then repeat this cycling 4-5 times. This will yield the best results the quickest. Hope this helps.

Alright thanks for this clarification! Then the best would be to always do full discharge/charge cycle?

Great answer! And what about letting the phone plugued in at 100%? Like a whole night? I've heard so much things, some says "it's better to always charge it a little when you can because it is bad if it reaches 0%". I know it's a chemical reaction and I know the internal resistor gets altered over time providing less efficient charge/decharge. When the phone closes it is because not enough power comes out of the battery, but the reaction is still there and by pluguing it we revive it.. right? That would make sense to me. That would mean that there isn't a charging habit killing the battery life more than another?

I generally like to unplug when full. The reason being, when it gets to 100% it discharges to 99% and the back to 100% it charges. Now in all reality you won't notice any of this battery dying with current gen li-ion batteries unless you keep a battery for like 2 years of use. But then you can always replace it. Bottom line is its not really worth worrying about. I don't know why people say letting it go to 0% is bad. The less repetitive charging, the better, this means letting it go from 100 to 0 as often as possible.
TL;DR it doesn't matter, your battery will outlive your new phone cycle

Thanks a lot for those clear answers!

Slow charging on 4.3 (Please Close This Thread Mods)

I've notice while flashing carbon, dirty unicorns, and pa among other aosp ROMs
That charging seemed to be slow for me. So I wanted to investigate..
I grabbed an apk called galaxy charger light https://play.google.com/store/apps/details?id=com.abmantis.galaxychargingcurrent.free
And when I refreshed it while plugged in to the wall charger, it said the max was 400. That's like USB currents. So I used devil kernel, and inside the latest devil tools, there is a charging control tab. I changed the options like I have here in this screenshot.
Then when testing my current with that galaxy charging app, it now says my current is 2000. And my phone is charging super fast now like it used to. ...And I thought my cable was bad lol.
so if you're charging is slow, try that app out and test it and see what your current is... if its 1800 or 2000 then that's good, if its 400 or similar, then you're charging very slow.
Also, I'm charging at 1500 through USB when it used to be only 475. Kind of like 'fast charge'
****But be careful. I've only tested this out for a couple days. So far no problems but change the charging control in devil tools at your own risk.****
please close this mods
and only change the USB control if needed. (I've heard something about "fast charge" messes up USB ports on pcs when charging that high but idk if that's true or not. I've only read that once and I forgot my sources)
You want the 'max' to be around 2000.
Before this devil kernel tweak, I had a max of 500 within the galaxy charging app. This was on stock carbon and dirty unicorns. Now my max is 2000 and its definitely noticeable. now my phone even charges while playing a graphic intensive game.
after doing some reading, this may be just too dangerous and damaging to the battery that its not worth it. please check the link by saboture and this shouldnt really be needed. i guess tw doesnt charge at 2000 constantly either so it cant be good. was def only trying to help but i dont want to steer ppl in the wrong direction.
Devil kernel thread - http://forum.xda-developers.com/showthread.php?t=2299261
And his devil tools are listed here - http://forum.xda-developers.com/showthread.php?p=41346443#post41346443
Hope this helps somebody that has slow charging problems. I know I did and it has helped so much.
Thank you, -cue
EDIT: this may be an isolated incident for me. anyway, you can check your max current with the aforementioned app and see if its happening to you before any changes need to be made.
Screenshot removed-- please refer to later post as to why...

Don't let your phone end up under the pillow on charge while you're asleep, it'll overheat like crazy at that current. I leave mine on 1200

The faster you charge, the faster your batter will die and it will also lower the life span. Be careful using this.

Good warning folks. Like I said, ive only tested this for a couple days so I'm glad your warnings are close to the op. I will edit it to stress the voltage warnings. Thanks! I haven't noticed heat that's why I've kept it. Will def watch it now. But I thought 2000 was equivalent to 2 amps which I thought our phone charged at originally. Obviously I don't have that much knowledge of electrical.. Better I learned from folks like you guys before I burned my face off lol
... unless the warning only pertains to USB charging. That I was weary of.. But nevertheless... Does make sense that it would wear the battery out though if it was too much that the phone can handle.
Was I the only one experiencing400? That is so low!! my phone was dying while texting and charging.. not right . never did that pre 4.3

Define "originally"
For who knows what reason, the Note 2 and other Sammy device ship with a 2000mAh 5V rated charger brick...but the TWiz software gimps the charger by throttling it way back to only 500mAh. Which is just downright stupid moronic. People on Note3 are amazed by how fast it charges, because Sammy has removed the software limiter in the stock ROM, and now the 2A charger actually charges closer to something resembling the charger rating.
As far as wearing out your battery, all rechargeable batteries wear out after a certain number of charge/discharge cycles. So long as heat doesn't become to high it isn't a worry. I've been using 1200mAh+ saoftware charging since kernels came out that allowed it. Still on my original battery.
Now regarding slow charging, another culprit that can do this is a crapped out USB cable. Try a different known good USB cable.

well i thought it charged at 1800-2000 originally on TW Stock. but testing now, its fluctuates around 400 to 700 on stock tw. but 1686 is the 'max' listed on that app. my 4.3 aosp roms were just staying at 400 and 400 was max prior to me using this tweak through the kernel. but is was very noticeable that i was charging slower than normal. will try a new cable today. thanks for your input.

[Q] N900T Extremely Slow to Charge- Tips?

Hello,
I bought a gently used N900T a few days ago. The device is awesome and works perfectly, except for one thing. Charging the phone with the Samsung charging cable+ac adapter takes longer than forever. It charges at a rate of approximately 8-9% per hour.
A few notes:
Device on, device off, it doesn't matter. It charges at the same slow rate.
The battery itself, once it charges, holds that charge very well.
The slow charging happened both when I was on the stock rom and on my current Slim Rom.
I have ordered a new charger and a new battery. If the slow charging persists with these new accessories, am I doomed? Is the slow charging a known issue for the Note 3? Besides the new equipment, does anyone have any advice on how to solve this?
Thanks so much!

You gonna have to do testing or replace phone. Me I would change kernel just cause it takes 2 seconds. Let it ride a day if no change then a factory refresh. You have checked that no app is killing phone as fast as it charges right?

Edit. I was just on his thread and a few guys having issues with either bad batter. UV/ oc .try a different ROM and kernel. Fresh install meaning Odin back to stock and start all over. Sorry good luck

As weird as this sounds, I tried the charger in a different outlet in my home and it works a lot better. The battery charges quite fast from any level to about 96%, then starts crawling again to 97, 98 and stops at 98. I opened battery calibration, which shows the battery at 96% and 4337mv, which is the same mv level as 100% normally if memory serves me correctly. So I'm thinking the battery is "full", but for some reason won't go to 100% without a fight. Perhaps if I clear my cache+dalvik cache? Any other suggestions?

What was wrong with mine it was the charger. The usb wasn't connected all the way in the AC therefore was only charging like it would through computer as soon as I fixed it with a blow of air and a gentle push it right away started charging AC phone charged in 2 hours

I could be wrong but I noticed my charging is slower when I stick my charger into a surge protector power bar as opposed to a standard wall outlet.

[Q] Battery life is so bad, it won't charge while in use

I am running BlueLightning-20140410-jflte as my ROM, with the 3.4.82-ChronicKermel-KK4.4-AOSP-JFLTE-v3.1 kernel.
I have my governor set to ondemand, with my low clock speed set to 189MHz and the highest at 918MHz.
With the sound set to one click past off, with Wifi, Mobile Data and GPS turned off, with the screen on the dimmest settings, my battery STILL drains when I have the phone plugged in, if I am actively using an app or playing a game.
I did not find a Fast Charge option on this ROM, and I had to uninstall Xposed Framework, because it was preventing several of my apps and games from running.
I can't think of a reason that the battery would still be draining this quickly, using the settings that I described.
Is there something I am doing wrong, or something I missed along the way somewhere?
Thanks in advance for any advice.

To what are you plugged while charging? If you are plugged to a wall-outlet, make sure you are using the Samsung wall adapter (or at least one that can push 1.9A). I've found out that it isn't usually the cable that causes slow charging, but the wall adapter.
Also, download an app from the Play Store called Charging Current Lite to see what your charging rate is. While 1900mA (1.9A) is optimal, anything above 600-700mA should be enough to charge while in use. Much lower than that, you will only maintain what charge level you have or slowly drain power.

It's usually the wall adapter, but it is not the one that came with my phone. I got mine off of Craigslist, and it didn't come with a charger. I've been using the same one I used on my old LG Optimus L9. I never considered that.
Figured that plugging it directly into my computer via USB would give a weaker charge, but never thought it could be the wall charger, itself.
I'll run those tests and report back. Thanks!

Charging via USB will put you in the range of around 480mA. Even with fast charge on, it's somewhere around 600-700mA.
