[Q] Battery Memory

So, I'm nervous about the fact that I can't replace the battery on my ONE. So far every night I've been staying up late until the phone dies, then plugging it in, waiting til the light stops flashing, then powering it up to charge while on overnight.
Problem is, this phone has awesome battery life. Right now at 10.30pm, I'm sitting at 41%, and debating just leaving it unplugged all night.
So what's the deal with memory on these batteries? How much, say over a 2 yr span, will charging a non-drained battery shorten its lifespan or lessen its capacity?

Lithium ion batteries are awesome. They are lighter, smaller and do not suffer from "memory effect."
Do not drain then fully recharge this phone on a regular basis. That will accelerate capacitance loss. Keep it charged as much as possible, avoid fast charging, try to use your PC to charge it overnight. Do not leave it charging for too long (i.e. days on end). Though on board computers can refuse charging, it is best to stay on the safe side.
2 years, you will definitely notice a decrease in battery life, but by the time it becomes intolerable, you will have upgraded. I can almost guarantee that.
EDIT: Please add to/refute any statements I made if you have greater knowledge on this subject, people.

Thanks! Can you explain why using mr PC to charge is better?

Because it's a slower charge at a lower amp rating prolongs battery life by not boiling the cells

As was previously noted, what you're doing is actually the worst possible thing you can do to a lithium ion battery. In general, best practice is to keep your battery somewhere between 10%-95% charge whenever possible. Once a month, you should "cycle" your battery under 10% (but not fully drained) to keep everything in peak condition. If you're ever not going to use the phone for any length of time, best practice is to drain to 40% and store in a cool, dark area.
When you first get a new device, you do want to condition it by doing three to five (varies on the device) full charge/discharge cycles, but after that, once a month with a conditioning cycle will take care of things for you. And again, as was previously noted, it's not a great idea to leave your phone charging overnight because you can't always depend on the battery controller chip.
These newer cells are all rated to relatively high cycle lifetimes, so I wouldn't worry overmuch. At that point, capacity is supposed to start degrading, although naturally it's going to happen a bit earlier for any number of reasons. I'd be much more worried about avoiding heat though than overcharge.

I'm assuming charging it slowly would keep it slightly cooler than a wall socket and closer to room temp, the better.
There is probably some other reason, but I'm not the person to ask. you can do some independent research. :good:
Just charge your phone when it needs it and don't when it doesn't. Do that and you'll be good until you upgrade no problem.
EDIT: Oh, beat me to it... haha
EDIT: Also, does the 40% apply to phones? Mobile devices never really turn off, they just go into deep sleep, I'm told. I was going to say that too, but then I remembered this. Does the 40% rule apply to non-removable batteries?

It's a question of how much voltage you're chucking into the battery. If you use a low-voltage wall adapter it'll be the same as if you were charging from your PC.
The 40% rule applies to any battery, and they'll all discharge over time anyway (connected or no). If you shut your phone off, everything powers down except (if memory serves) what's necessary to run the internal clock. The impact that has should be pretty minimal (unless you're trying to bury your One for a thousand years, in which case...can't help you there).

Who would buy a low voltage wall adapter?
And yes, I would like to bury my One safely for a thousand years, so when it is found by the generation of humadroids, they will see it and be amazed that a civilization so primitive could achieve such technological mastery.

I don't know that I bought any, but I have a few lying around from yesteryear's gadgetry.
And at that point, why not launch it into space instead, a la HTC Nexus One?

So I use my phone as my alarm clock and also run the Relax and Sleep app all night. Otherwise I'd just plug it into my lappy throughout the day and not worry about it.
But that raises another question: running the phone overnight while charging it at the same time. Bad juju?
I plugged into my lappy last night around midnight, woke up this morning and had about 95% charge, rather than the usual 100%. I'm assuming this is the result of power output for Relax and Sleep cutting int power input from charging.
I've also been in the habit of leaving my EVO 4G plugged in while tethering. I assume this is also a bad plan?

MOST of this advice is 100% true.
The only part that is not correct information is the advice to not let it die. It is perfectly OK to do this as long as you don't deep discharge the battery... Example like let it die then not charge it for like a week or something.
The science behind this is the fact that lithium ion batteries actually have a nominal voltage operating range which is like 3.2 - 4.3 volts or something like that. Your device is designed to shut itself down when it gets to about 3.5... This is done to protect the battery from deep discharge cycles.
Letting it die is perfectly alright. Just make sure you charge it soon after.
Also, you don't need to use your PC to charge it. That is in no way necessary. Your device came with a wall charger for a reason...
There are safety features built into the kernel and cable to keep you from damaging the device during charge. Use the wall.. It is perfectly safe and faster / more practical.

Your battery will automatically cycle between 95%-99.9999% to prevent overcharge, so you're fine on this front. You probably just caught it on the low end of the cycle.
The issue with charging + tethering is that a phone draws more power when plugged in (ramping up processor, etc.), and tethering eats a lot of power. More importantly, both charging the battery and running the antennas for tethering generate a lot of heat. So long as you watch your battery temp (most good tethering apps will toss in a temperature gauge, although if you're using stock you'll need another solution), you should be fine, but heat is one of the fastest ways to kill a Li-ion battery.

Although a full normal discharge (phone powering off) won't kill your battery in one go, it's a deeper discharge than I would recommend on a regular basis. Things are built with margins of safety, but I don't like playing on the edge when I can avoid it. The difference between 10%-15% isn't too much either when it comes to my use-case either, so I'm content to bounce between 20/30-95 most of the time.

Charging while much power consumption

It is really bad that it is not possible to do whatever I want on my phone while it's already plugged in. Will there be a way to increase charging current for example?

Normaly,
I underclock my kernel till 1.5 Ghz.
I still have no lag, and the charging goes better.
Maybe you can try it.
But underclocking needs root.

Yeah underclocking helps A LOT when charging and when you are just doing normal stuff.
Normally I never take my clockspeed over 1.6-1.7GHz(ondemand/interactive) because I really see no difference, the only time when I take it up to full speed is when I am playing Asphalt 8 because that game looks gorgeous and it needs power.
But you will need Root @chitose_ndy said.
Another thing to do is to see if your power outlet is fully functional, I had a problem 2 years ago where my power outlet was having some problems so it may cause problems if it is not functioning normally

I am currently using the charger that comes with the SGS4 and it is slightly better (experia Z1 charger comes with output 1.5 A while SGS4 charger has 2A output). However, Chargers with support to 2.0 quick charge (with output ~4A) will be released early 2014, till then there is nothing we can do to significantly increase charge speed.
underclocking would help for sure, but keep in mind that it won't increase charge speed but it will reduce power consumption.

How to Fast Charge N7000

I'm using a newly bought battery and original charger still my phone take 4 hours to charge full I'm using pa rom even on stock it take 4 hours how to fix it?????
Sent from my Galaxy Note using XDA Free mobile app

Ain't that normal? What's the capacity of the battery?
Gesendet von meinem GT-N7000

There's no official fast charge ROM support available for Galaxy Note.
You can increase the charge speed my optimizing your battery performance. Most Samsung phones take 3-4 hrs for charging depending on the phone state.
Make sure you clear all apps before keeping your phone for charging as any running app can eat up the battery. Look up for any suspicious apps which may be eating up battery.
Use CPU spy to make sure that your phone is going imto deep sleep while charging, if not there's a malicious app which is keeping up the phone awake or there's problem with the ROM you're using.
Also check that your phone is not getting heat up while charging, as it could mean a great power loss which could highly affect the charge time.
If nothing works try changing ROM.
Or at the last case if you are a regular ROM chamger then try to clear up battery stats through some app available from play store which requires root.
One more issue which I once encountered was with my charger cable being faulty( although no signs of physical damage) and I changed it with a locally bought cheap cable and miraculously my phone stopped heating and charged faster.
The more you care for your device, the better it gets.
Hope I have helped you.

I checked my 2 Notes, max current it draws is limited by the charging circuit. Seems no kernel can change that value in the Note.
It charges max at 1 Amp, no matter if you attach it to a charger that can deliver like maybe 1000 Amps, the max current is 1 Amp.
That 1 Amp is also until it reaches about 90% ... since Li-Ion is very picky and actually dangerous when overcharging they slow it down.
It's a statement that I hear often in the wrong context : I bought a new battery and it takes very long to charge. Actually that is a sign that the battery has a big capacity. You can only take what you give.
Of course the charger and cable are very important. I would advice everyone to buy one of those usb charger doctors. http://forum.xda-developers.com/showthread.php?t=2451375

Charging Yet Decreasing

I've been using Z3+ for quite some times now.
Since the first time I bought the phone (which was a second-handed phone) I only have one question.
If I charged my phone and used it, it wouldn't increase the battery percentage(s) or it would be so slow to increase.
I installed this app called AccuBattery to give me info the status of my battery, is it losing or gaining.
And yes, it lost mA (-86 - xxxx) while I was using the phone. Is it normal?

Yes its normal

This is not normal. Buy an original Charge. Use regular wall plugs, not extended plug sockets. But I warn you, phone gets very hot if you use it while charging. If this charger method doesn't work, go to sony service and ask for battery replacement..

Yes it does that with other chargers, I swear I have 4 chargers in my house and none of them were up to the task to charge this phone efficiently so I bought an "adaptive fast charger" and no complaints since. While playing game it still charges a bit slow but it doesn't decrease any more.

Ohhh am sorry, if the screen is off it will keep charging up, but I was talking about charging while using my phone. Sorry to be ambiguous.
Ummm.... Okay, I guess I'll find Samsung Fast Charging later. So sad that Aukey can't keep make my charging stable.

You need to use a Qualcomm charger with Quick charge 2.0. This is not the same as adaptive quick charge. Qualcomm quick charge 2.0 is built in to the processor. It works even if you change ROMs. It's the only one that can keep up with the phone's demand, and can charge the phone in just over an hour. I've had the phone since before it was released in the U.S.

Don't expect this phone to charge any faster with QC2 for example. And if you watch videos or even pay games, I can imaging that the device will heat up (because SD 810...) and the charging speed will reduce itself drastically. Or even discharge. I don't know why but QC doesn't work on this phone at all. Even my Z3 tablet charges up faster with QC than the Z3+.

Iam using Sony UCH10 quickcharger 2.0, and when i play heavy game, battery percentage stay at one place or it decrease...its because the phone consume more energy than battery can give... And yes,its normal.

Question Mi 11 Ultra charging slow while gaming or using

Mi 11 Ultra is charging really slow when I play game or even do a normal surfing or using whatsapp
It's really irritating. Any fix for this.? Is it a software or hardware limitations.??
PS: Phone charges really fast when it is locked nd kept aside. Using indian variant and 55W charger that came with box

Its not 67w charger?
It could be a heat issue. If the phone is too hot, specially when gaming 3d it reduces the charging cause it has control temperature module.

In India we got 55W charger with box. And coming to the point, I agree during gaming it might charge slow due to heating issues. But during surfing nd whatsapp-ing if I charge then also it's god damn slow, do u face same issue.?? Can u pls confirm
When locked it charges really fast.

what is your ambient tempeture? it also affects it.
Thats the reason why some people get the 38min charging from 0 to 100 and others get 45min or more

That's definitely no issue! The Snapdragon 888 heats very fast and while charging even more. So there is no wonder it will reduce the charging speed to cool down while using the phone.
