normal charger - Nexus 6 Q&A, Help & Troubleshooting

Hello
Bit of random one but can I charge my nexus 6 with a normal charger say my old Samsung s4 charger?
Don't want to damage my battery or phone but can't see why it would but would rather check.
I'm guessing it will just take longer to charge?
Cheers lee

sure, you can use any compatible charger. but to warn you, most normal phone chargers will just take MUCH longer to charge the n6.

Yea no worries on the time. Thinking slower charge over night might be better than leaving it plugged in fully charged for longer. Plus I'm a believer about running battery flat for the first few charges and only have a normal charger at work which is when it will run out next lol

1) You *cannot* run the battery flat. The battery chip WILL shut you down when the voltage drops below a certain threshold.
2) Li-ion batteries DO NOT do well with being deep cycled. The lower you let it drop, the shorter the battery life. This is one of the reasons why they shut you down before it goes flat.
3) The battery has to have a minimum voltage in order to power the circuit that controls charging. Yes, if the battery level drops too low, YOU CAN'T EVEN RECHARGE IT.
It is better for the battery to charge slowly, and to top up frequently.

AC Power Cable Option

Just wondering, I found these:
http://www.amazon.com/exec/obidos/t...t_shr?_encoding=UTF8&m=ATVPDKIKX0DER&v=glance
They are the correct micro USB charging units, but they are designed for Blackberry smartphones...Will these properly and safely charge our HD2's?
I love the folding plug design.
Hello Free Man:
FWIW..I had purchased one of these exact items from amazon. Haven't used it yet but I read the backpanel and the output is 5v @ 700ma. If you look at the backpanel specs for the wall charger shipped with your unit from HTC it'll show 5v @ 1A on the output. So the unit will work but will take slightly longer, I think.
Take Care
Well as long as it is safe to use, mine should be here in a few days. I would think it would simply take 30% longer to do a full charge and I am only really using the unit to charge overnight when on the road in hotels, so that is really not an issue as a full charge only takes a short time.
Anyone else want to step in and comment on the lower rating?
You are correct, this charger will take longer to fully charge the battery.
Just like charging from a PC USB port takes even longer since that only provides 500mA maximum.
It is absolutely safe to use chargers with lower ampere rating, the downside is that you will either get longer charge time it your device won't charge at all. But nothing will burn or explode.
So you are saying my device will charge safely, just take 30% longer? You mentioned something about it not charging at all, why would it not charge?
Will this shorten the batter life or anything to that affect? Thanks!

It may not charge at all if the device you are charging needs a certain amount of amperage in order to charge the battery.
No, this will not affect the battery life or anything to that affect.
Thanks, I plugged it in and charged it for 3 minutes and it did begin charging from 69 to 80% in that period, so it works fine and is quite fast. This battery charges fast in my experience.

[Q] Any disadvantages of frequent charging?

Are there any disadvantages to having the phone plugged in a frequently as possible (e.g. charging over night, car charging, charging while at work)? I have been favoring 897 leaks over 9000 roms mainly because of battery life. I have been a fan of Apex roms and now that A11 is out I want to give it a try but I know I won't get the same battery life as Illuminance. Could I damage my Captivate from frequent charging?
Now i could be wrong, but frequently charging *may* reduce the life of the battery....i believe every batter has a certain amount of "charging cycles" it can have before the battery begins to lose charge quicker...again, i could be wrong..
True, batteries do have a certain account of charge cycles, but a charge cycle is a 100% drain and back up again.
So down to 50 then charge, 75 charge, 75 charge, is only 1 full cycle.
So whether you wait to charge til it's dead enough to not run the phone (it actually shuts off before true 0% to save the life of the battery) or you grab some spare juice when you can, your battery should have about the same life span.

Ya this is true but I find I that I get much better battery life if I do a bump charge. Ive charged to 100% on the phone screen, turned off the phone, plugged the charger back in, and had it charge for another half hour until it hit 100%. So I dont know what it is about charging in that fashion that works for me but it really seems to help. I also am pretty good about cycling my battery 0-100 100-0 so that may help.

bump charging will kill battery life long term..
Also, be careful with car chargers. Some of them are designed to charge faster which will also shorten the over all life of the battery.
Lithium batteries don't like to be drained fully. The best time to charge is 30-40%. Also lithium doesn't like the "fast" charge. Basically be easy on the drain/charge/level and it will last longer.
The 1/2 hour you're talking about is because the last 5-10% takes the longest. You can actually charge from ~40%-80%+ very shortly due to the way Lithium works.
As I said above, the phone shuts off before the battery reaches 0%. You notice it still has enough power to run the charging animations even though its too dead to boot.
the phone also stops charging at 100% let drain to 95 and back up, to prevent overcharging.
both are to save the lifespan of the battery.
Discharging below three volts will cause damage. Charging over four point two volts will cause damage. Charging at a greater rate than one C will cause damage. One C is equal to the capacity of the cell. Our stockers at 1500mAh should not be charged at a rate greater than one point five amps. I believe the stock charger outputs 800mAh, or point eight amps. Any damage to the cell will definitely shorten life. The more you use a battery the faster it will die, true with any type. Hope this helps someone.

I don't really see this as a matter of choice. My phone dies daily, so I have to charge it daily; I have to bite whatever happens with it anyway. If it helps, I got my phone on launch and have been using the same battery through my warranty replacements. My battery maxes out at roughly 15 hours of moderate use, 20 of light use.
frequent charging reduce battery life so it is better to charge when ur battery is left with 15% or below and charge it completly

This is very true of Lithium ion batteries. They like to be kept topped up constantly. Not letting it go to 0% consantly helps. This is very different from NiMH or NiCd, where the "memory" effect requires you to completely discharge the battery before next charge.
The best way is to just put the phone on charger whenever you are not using it - if ever - just plug it in and let it sit till you use next time.....
FFS how many times must I say it? THE BATTERY NEVER REACHES 0%!!!
There is ALWAYS some amount of charge even when the phone won't come on.

Very true. If you discharge a lithium cell below three volts, you run the risk of it catching fire or exploding.
Should've mentioned earlier that as the battery degrades, it loses capacity. This is what causes them to seem they're not "lasting as long" or "draining faster".

Does Adaptive Fast Charging Come Pre-Enabled on the Note 4?

Was wondering, Does Adaptive Fast Charging Come Pre-Enabled on the Note 4? Or do we have to go to the Battery Settings first to enable it?

When I got mine, it was enabled already.
Oh, if your fast charge your battery once, does it reduce your battery's lifespan in the long run, or does it need to be fast recharged several times for a notable difference?

As a general rule, the faster you charge the battery, the hotter it gets. The hotter it gets, the more quickly it will degrade. I still use my S3 charger to charge the Note 4 overnight.
Does it really make a noticeable difference? From what I've read, probably not. But I don't think there's been much objective testing. Just using fast charging once is highly unlikely to affect it in noticeable ways at all.
If you've charged the battery once using the fast-charging method, is that going to impact the lifespan of the battery? Or does it take multiple fast-charges for the battery to begin to loose its charge?
Nowadays I use the regular 2amp Samsung charger that came with my Wireless Charger.

I edited that in right after I posted, but I guess you beat me to it. As far as I can tell, it's a gradual process. Unless the phone seriously overheated during the one charge, it shouldn't have much effect at all.
Thanks, looks like I don't another one of the Fast Adaptive Chargers after all, haha.

Honestly I'm not sure if it diminishes battery.
I have to take it off because I'm using a Zerolemon battery and it doesn't charge all the way up unless the fast charging is off.
The adaptive charging is built in as long as you're using the included charger. It charges at a higher voltage so it's not as damaging as say, a 3 amp charger would be, but it takes many many fast charges to affect the battery's performance. Generally speaking though, the faster you charge the more capacity you lose over time, but the worst thing you can do is charge it &leave it plugged in for hours fully charged. I use an old Bluetooth charger that's 500mah when i charge overnight & the fast charger at work or in the living room.

Will charging past 100% harm my battery?

Hi guys, I just bought the TurboPower charger from motorola since my (refurbished) N6 came with only a usb cable. I am very happy with the blazing fast charge speeds but was wondering if continuing to charge the phone after it reaches 100% battery might have any adverse effect on the battery's health or lifespan? A quick google search revealed little consensus so I'm hoping for an expert to chime in on here.
I tend to charge my phone overnight while I sleep, so with the new charger this means several hours of charging at 100% battery, and naturally the phone gets reasonably warm when undergoing such rapid charging, so I'd like to make sure I'm not causing long-term damage! (especially given that I'm not going anywhere near the Huawei N6 if it really has that hideous raised black bar on the back for the camera :/ )
If indeed this is bad for the battery - would using my (slower charging) old Nexus 4 charger overnight be any better? Or is it a bad idea to mix chargers from different phones? Generally this is a question I've always wondered about actually so it'd be good to finally find out.
Here are the charger's output specs from the motorola page in case that's relevant:
Output
Standard: 5V / 1.67A (8W)
TurboPower: 9V / 1.67A (15W)
TurboPower: 12V / 1.2A (15W)
No. use the normal charger for overnight and turbo charger on the go. or outside.

"No" as in "no it won't harm my battery to charge past 100%"? If so then why bother with the old charger at all? Sorry if I've misunderstood your answer.

The turbo is not always on. The M-charger switches to standard when the battery is > 78% charged. So at night your 6 battery is not permanently charged with turbo
The N6-bat has a high capacity of 3400mA/h and suitable for turbocharging.
I use the M-charger with a cheap qi-pad for wireless charging at night. When connected to the Qi-pad the M-charger acts like a standard charger.
When needed I connect the M-charger directly to the phone.

the previous answers are both correct within a certain context.
all batteries have degradation from charging, although constantly subjecting it to the excessive heat of turbo charging will speed this up.
maybe it will take a year or 18mos before you realize the charge isnt lasting as long as it used to, maybe less. its a guess really.
the point is, dont subject it to turbo charging unless you really need that option. it is the best way to maximize the life span of your battery.

While I agree that all electronic components lifespan is reduced by excessive heat, I don't think that answers the question fully.
Regardless of the charging method employed (standard or turbo) you will not reduce battery lifespan by remaining connected to the charger at 100% capacity.
The method you use to charge a depleted battery to the specified value governed by the phone which disables turbo charge, the increased heat "may" reduce its lifespan.

no it wont. it may just take longer if it cant meet the phones standard charging needs. it would actually be worse for the charger than the battery if it couldnt.
i generally charge mine from an outlet strip with usb charging built in i got off amazon.
a common misconception about chargers is bigger is better. thats generally not the case.
for instance, a charger can state an output of 3a. all that means is the charger "can" output 3a, not that it pushes 3a to the device, because thats simply not how it works.
the device will draw what it needs of that 3a capability. it may be anywhere from 0 to 3a. there is charging circuitry in all devices that controls how much charging power the battery is allowed to have. if you give it less than what it wants, the battery will just charge slower.
hope that helps.

actually, reaming connected to any charger while at 100% is not recommended.
the last 5% or so is the worst state for the battery, as is basically tries to cram the last bits of juice in there. when you stay connected, its repeatedly topping off, which is repeating the added stress of getting the last bits of juice in.
im sure i didnt do the best job of explaining that. if you have some free time google "battery university". there is some very good info on there about what im saying, and about li batteries in general.

Trickle charging is not desirable, topping off isn't bad if the charging method doesn't top off to the threshold voltage (Eg. 4.3V), so I guess without more information on a specific device employing a lithium-Ion battery It's hard to say for sure if remaining connected to the charger causes adverse affects.
If you want to get down to the few days or weeks you'll save on the lifespan of your battery you might as well turn it off during each charging cycle to avoid parasitc load, as this can degrade lifespan more than topping off.
I guess it comes down to personal preference overall. Do you want/need the convenience of leaving your device always on (minus occasional reboot) and you prefer starting off with a full capacity battery each day? Or do you prefer your battery will enjoy it's entire intended lifespan? Me personally I choose the former since I don't like to miss calls or notifications while charging and I don't keep a smartphone much longer than a year anyways.
In this thread I read several good suggestions about charging.
But don't forget discharging. Charging, turbocharging and also discharging will shorten the battery life.
Actually, when laptops first came out, if you overcharged them, the battery would explode! :laugh: Luckily engineers designed a way that Lithium Ion batteries dont do this anymore!
charging past 100% will not damage your battery. ive been doing it for the past 10 years. at one point, it would damage the battery, very sightly, over long periods of time. but in todays times, it won't damage it. first off, 100% isnt when it stops charging. it stops charging once it reaches a certain voltage, which is ysually after you reach 100%. yes, even though its plugged in, it will stop charging. and then will charge again, after some voltage leaves it. it will not take in an extra charge. once its done charging, its done, and will not charge more.

+1 I do the same with my M-charge, my qi charge turns off when the phone reaches 100. It doesn't drain that much when it is done charging usually it's still at 100. Before I got root and greenify, it would drain to a max of 4% by the time I woke up.

Question about fast charging

Hi everyone, I'm new here with my Note 9 coming from a Galaxy S5. I have 2 questions.
I want to know firstly what (wired) charging do the majority of Galaxy Note 9 owners employ? Standard or fast charging? I am very weary of fast charging because of increased battery degradation.
My second question is this. I am assuming that fast charging increases battery degradation because of increased heat from the higher voltages. And yes I know that it is adaptive and gradually tapers off. I have run an experiment. I have installed a couple of battery temperature apps and charged through standard charging. Then I have put the phone on a solid piece of steel plate and charged through fast charging. The temperatures of the battery are identical. I have checked this a number of times. The steel plate even at room temperature is quite cold.
So does this mean that if I fast charge with the phone on a cold steel plate and the temperature is no higher than standard charging resting on a usual surface, that fast charging in this case causes no additional battery degradation?
Thanks.
Fast charging, most of the time
Fast wireless charging all the time. Even when it's in my car dock it wirelessly charges in that can be for 3-4 hours a day on and off depending on journey. Screw battery degradation I'll use the upgrade programme to upgrade next year.
Slow charging. I have the same concern as you hence I off the fast charging function. No diff to me since I charge my phone only at night when I am about to sleep. Do not require charging to be fast.

If you plan on keeping your Note 9 as long as you did your S5 then slow charge with wire and also try your best to charge from 40 -80%.

Samsung is claiming 95% battery charge capacity after 2 years (80% is normal). So there is little reason to hold charging to 40 -80% for the normal lifetime of a phone. And also LION batteries are never allowed to charge or discharge completely - it's hazardous. So Samsung is already limiting how much power the phone can draw or charge the battery. (So do electric car manufacturers)

A quote is worthless without a source, where did you hear Samsung state the phone would have 95% battery charge capacity after 2 years? Also I'm not sure you understand Li-ion batteries, they are allowed to be fully charged but not completely discharged, this is included in the mAh ratings. Also electric car manufacturers do infact recommend something similar to 40 - 80% charging, for example, Tesla by default do not charge 100%. Even Elon Musk recommends 30 - 80% charging: https://twitter.com/elonmusk/status/448466037441179649
I use slow charging. I believe it is quite fast even with slow charging.
If there is an option to choose whether you want fast and slow charging, note that fast one has some downsides.

Although I don't blindly trust what manufacturers claim, I did however test my wife's note 8 and used accubattery pro on her device from new. Unlike me, she would always topup her phone and also fast wireless charge. After a year prior to her trading her note 8 in for a note 9 I checked the health tab, I know it's not accurate however as a ballpark is stated her battery health was at 97% which isn't pretty bad for 12 months of usage. My note 8 was at 99% using the 40-80 rule approx 90 % of the time. If one was going to keep their device longer than two years I'd still recommend using the 40-80 method to prolong battery life. However most Inc myself upgrade yearly so it's all moot. I just do it (80-40) out of habit.
