does anybody know some patch to disable USB charging? i dont like messing like that with my battery, i like charge it to 100% and then discharge to 0% every time, but oftem i need to copy some files from cell to comp... and i must plug in cable and charge battery for few minutes... help? thx.
Sory i dont answes your question but i really must ask why from 100 to 0. Afaik i even worse discharge this type of battery to 0. You can even broke it. Just charge when you need and life time be same.

Draining to zero is bad for newer batteries. And charging them for only a few moments is fine. All newer phone also have smart chips so when they reach 100% the stop charging usually letting the device bounce to 95 and back up.

actually, it does not drain to the zero.. just a minimum value. if it were to drain to zero it would never charge again.
i'm talking basic chemistry here. not sure about the exact Li-ion batteries.
@OP, my old sony phone, you could shut it from the service menu you get after clicking a set of combination of the keys..
there must be a similar combination for the new ones. i am on cm9 so i cannot check.

battery has its own electronics and it never go below safe limit, and charging from 0-100 is good for my battery as far i can tell from service menu where actual measured capacity is shown, normal is 1500, when i charge whenever i like, plugin and plug out several times a day capacity drops even to 1400, when i charge and discharge 0-100 100-0 capacity comes back to 1500
i had xperia arc before and after 9 months battery was like new, sometimes it dropped to 1425 but after few full zero zero full cycles it was back to 1500

Look, right is we have mobile phone for using, for serve us. If i need go out and see 50% i give mobile on charger. Who really want have death mobile? And when mobile turn off and you give him recharge too late, like after you come from out you can really broke it. This already happen on my old se batery. And still i dont se any cool reason to do it when lifetime battery is practicaly same as i read on many same about li-pol li-ion battery. Anyway if there is no other way to disable charging, you can also use something like airdroid and copy files via wifi

There is no memory effect on our phones' batteries. They do not lose their capacity like this at all. I do not know, how/what you did, but this is not correct.
You could go to Google and search for Li-Ion and Li-Po type battery myths and reality(facts). You will find lots of useful information.

Kinda sorta....the modern lithium battery does not have a memory like the old nickel ones. But what happens is as your phone charges/drains it builds statistics to know what zero percent actually is. So your battery doesn't really physically store more power, your system just learns what full and empty mean for your battery and your phone just reports a more accurate battery percent.

If you drain your battery to 0, it will be unusable (will not charge), you'll have to buy a new one. The phone should shut off before it reaches 0 to help keep this from happening, but I have not tested this with the Atrix.

I mostly use the one I got with my Moto headset. It's 5.0/550mA and it works pretty well. I use it when sleeping (keeps wifi/pandora running.)
Haven't really bothered trying to time either one, though. Mostly I use the headset charger due to having a much longer cord that isn't as stiff as the usb one. I have to use an extender on that one and it's annoying.
Go to Monoprice they have ten foot USB cords under $5.00 dollars best place to buy any cable needed.

This is the biggest myth about Li-ions. Every lithium ion battery MUST have regulatory circuity built INTO the battery for safety reasons and so it can actually take a charge. This regulatory chip also prevents the battery from dropping below an actual power level of around 20-25% (not too sure about the percentage). Yes, you CANNOT drain a lithium battery fully unless you're using naked cells with some complex machinery. And yes this also means that your battery actually has MORE life than it says. but no you cannot access it.
This spare life does however increase the batteries life span because the cells go through fewer charge cycles.
You don't need to drain your battery fully to make it perform better. I can't link (new member) but search google for lithium. Battery care and hit the batteryuniversity link. It explains everything.

All phones shut off before they are completely dead. You are also slightly incorrect, the thing that makes the battery unusable is it draining below a specific voltage, usually 2.8v. You would'nt have to buy a new phone, just a new battery. But this is nothing to worry about because the phone is not capable of draining it to that point.
First and foremost...lets get this out of the way..if u want more battery life..get a newer more powerful battery...thats the best option..
But if you still wanna stick with your current battery and still want improvements..here is a little something i want to tell you..
Obviously you might have searched about how to improve and come across the method known as calibration.. this is the method as described by one of our members..
nickrule1896 said:
Steps:
1. Before flashing a new rom, use root explorer (with read/write set) to delete the file "batterystats.bin" stored in /data/system/.
2. Charge your phone with it being turned off.
3. After it is fully charged(100%), take out its battery without plugging off the power supply.
4. Wait for a few moments, and a ? sign will appear.
5. Put your battery back in. You should see that the battery percentage increases quickly to 60%. If it increases to 100% with seconds, please skip to step 6.
6. If it stops increasing at 60%, let the phone continue to charge until 100%(takes quite a while)
7. Once it reaches 100%, let it charge for a further 15-20 minutes.
8. Once that's done, you can boot to OpenRecovery and flash your rom!!!
Alternative way of calibration(thanks a lot zeppelinrox!!!):

If you dont believe me...then read this post..http://forum.xda-developers.com/showthread.php?t=1460553
and subsequently read this post by Google Engineer Dianne Hackborn(funny surname i tell u) and you'll finally believe Battery calibration is just a myth..unless ofcourse you dont believe you know more about Android than the people who designed it
https://plus.google.com/u/0/105051985738280261832/posts/FV3LVtdVxPT
As is mentioned.. "It has no impact on your battery life" !!!
So...BATTERY CALIBRATION IS JUST A MYTH!!! Still...if you dont believe me..continue following your stupid practices..
Coming onto bump charging...
When your phone shows u fully charged it is actually charged only till 90-95% and thus u may experience a sudden decrease in battery %age after u unplug the charger...
The method for bump charging as you ardent ritualists may already know is as follows..
" Phone on, charge to full
Shut Phone off, charge to full
Phone back on, charge to full, use like normal. "
The main disadvantage of this is that it increases your battery voltage...Also in some case of sudden overvoltage while charging this can damage your battery...what for? 5% increase...
also..all that extra heat is bad for the lithium batteries...
Therefore 95% battery is good enough for daily use
so..if you really want to improve battery life...dump all these methods and just buy a more powerful battery and give it a month to give you proper results..all new batteries require at most a month to work to their full potential...
P.S. : come to think of buying a new battery...this idea may be very helpful to you if you do happen to own a Galaxy NOTE..

If this is all a myth, and I'm none the wiser, why is my battery percentage all over the place? For example, went on a hike listening to music etc. Ran the battery out. Got home, plugged into charger, turned on and it said I had 46% though when I first plugged it (while off) the battery symbol showed obviously barely anything.

Android is very....insensitive when it comes to battery .
Android keeps track of the battery using a permanently running Battery Service , which polls at a certaon interval....
For our phone , deep sleep will affect battery polling and thus your battery will be displayed as being larger than it really is .

Heyy guys I have a problem regarding the battery life on my fone
On any rom be it cm7 cm9 or cm10 whenever i charge my fone to say for eg. 65-70% and unplug the charger battery starts draining quickly until it reaches a particular point like (45-50%) then the drain becomes somewhat stable
However when i charge the phone fully (ie.100%) the battery depreciates economically (like on stock)
This means I have to charge the battery full in order to prevent for drain
What should i do to prevent this from happening? Or should I buy a new battery
Any Help Appreciated
In my experience with any lithium battery not just android increase battery life by let it die fully so it wont turn on at all then charge till 100% and no harm done by leaving an extra 20 mins leave charger in while turning on should vastly improve an older battery

I am afraid you're wrong in letting old batteries to drain completely man...when battery is new like say within 150 cycles what you said is true but as it becomes old it's better to charge it when it goes below 15...coz the chemicals will become inactive and won't be efficient in taking up charge

What about Die Hard Battery Caliberator? Got me rid of bump charging.
Good evening all.
When i'm charging my battery with wall charger our pc charger. I cant fully charge to 100. Its saying fully charged but after i unplug its going down to 96 our even 65 percent. And another thing was when is was charging my battery it was at 86 and after that the battery was going downwards instead of upwards ( when in charger ). So i searched on the internet and i found a way to calibrate the battery,turn off foon let it fully charge,take battery out 180 sec and put back in and it should be calibrated. But my problem is i cant get it fully charged because its getting downwards. Even now its stuck at 81 percent and not going furter. annyone got a solotion. Thank you in advanced.
I hope you get an answer, I have had this problem before but changing ROM seemed to fix it...... Please don't ask me to many questions if any, I'm pretty sure I'm more of a noob than you

The standard answer you will get from most people on here is "its been covered many times before."
However, I will tell you its the fuel gauge chip. Several charge-discharge cycles should correct the issue. Very common when swapping ROMs.
For example, for the hell of it, I just reset my chip and dropped from 63% to 2%. The chip kind of "learns" over time what full charge and empty is, and drifts about a bit until its fully sure what 100% and 0% are.

The weird thing is,when my foon is on. The battery shows like 49. And now i turned foon of,and its seems like the green battery is like 15 our something. I also did wipe battery stats again. And whent back to a stock rom.
I would buy a spare battery, you'll get an official 1 for £10 to £15, that way you have a spare and will also be able to set if your phone or battery has a fault.
With my battery I did few bump charges (replugging it back in after it says 100%) and the battery life is excellent. I don'the let it drop below 15% if I can help it.

Problem solved i think.

Now i found out that my charge conector on the phone,has a bad conection.
So i think thats why it issent loading our stops loading at a sertain point.
Sending back my s2 and hope to get it back soon.
Thanks you all for the help. And have a nice day.
What's the best way to charge the phone? Like do I charge the S3 to Fully Charged and then disconnect and then use it till it dies or charge it when it drops to a certain percentage?
The S3 uses lithium ion batteries. Try not to ever fully discharge the battery, it degrades the battery considerably. I would fully charge it whenever I get a chance (or up to 90%) then recharge it within the 20-10% range.

Doesn't really matter, you won't prolong the life of it notably in any case. And the small gains are definitely not worth the trouble.
Just use it like you want and replace it in 2 years time. It will have degraded by that time, however you use it (even if you don't use it actually)

No. It won't damage anything. Just know the more cycles, the more wear. Continual bump charging may shorten lifespan. Not what I consider damage.

Just don't let your battery fully discharge or get too low. Always recharge it as often as you can, especially in the range of 10-20. Also, don't leave it plugged in for to long when it is fully charged. Follow these three steps and you should be good.
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.

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.

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?
(sorry.. by whatever reason my reply got posted 4 times.. so strange. I try delete the first three but cant)..

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.
