[Q] Does fast charging affect long term battery health? - Nexus 6 Q&A, Help & Troubleshooting

Does fast charging Daily overnight reduce long term battery health? Is it a better choice to only fast charge when necessary and normal charge overnight?
I've reading about this lately but never came across a definite answer. I was hoping that someone could answer this for me.

Depends on quality of the battery and the capacity of the charger.
In general batteries are charged with 10% of the capacity. For the Nexus 6 battery with a capacity of 3200ma/H, you need a charger with a capacity of 320ma. Assume you need 10 hours to fully charge the N6 with a charger capacity of 320ma.
In theory the N6 charger with his capacity of 1600ma will charge 5x faster.
But the the N6 charger is not permanently in this turbo mode. After some time it switches back to a lower capacity when the battery is partially charged.
Now your question. In turbo mode charger and battery dissipates heath and that is not good for the battery. So normal charge will be better.
But there is also battery drain when you use the N6, especially the nice amoled display.
Battery drain causes also warming up of the battery.
So the total battery life depends not only on (turbo) charging. Also the way the N6 is used.

Use QuickCharge charger for overnight charging?

QuickCharge is a nice feature, yet I'm not sure if it's good to use this for overnight charging. Since it's not all that great for a battery to be charged to 100% all the time I was wondering if it would be better to use a normal charger for overnight charging so the battery won't be up to 100% in 3 hours and then recharging again and again whenever 95% is reached.
I thought it would be better to use a normal charger which takes longer to reach 100%, and only use QuickCharge chargers when you need the phone charged quickly during the day.
I could, however, be very wrong at this so please anyone with knowledge on Li-ION batteries please clarify this. I know for a fact that it's not good for the battery capacity to always be around 100% and it is far better to have the battery consistently between 40-80% to get the best lifespan/capacity out of the battery..

Do you know where to get one of these chargers? I can't seem to find any on the internet!

Concerning the Nexus 5 battery, how do you recharge your device?

Hi guys, good afternoon, how are you?
As I was looking after the Nexus 5 and the battery life of the device began to get discussed, I was unaware of the fact that nowadays we can just charge the device however we like, using Lithium-ion polymer batteries, different from the past, when a full recharge was recommended for the battery performance not get affected.
Considering that, for some users the battery life shouldn't be a concern, mainly for those who have a power outlet nearby, making an option to recharge it at any % level before getting it to fully recharge during the night.
I'd like to know from you guys: how do you recharge your devices? Do you wait for it to drain every % of the battery before recharging it or just plug it on the power outlet whenever needed?
Also, do you guys believe that recharging it at any % level does not affect battery performance?
Thanks a lot!
Modern batteries have a finite number of charging cycles before they being to lose performance. Generally speaking, 100%-0% is one discharge cycle, so if you want to maximize battery longevity you should do your best to minimize the number of discharge cycles you subject the battery to. It is not strictly speaking a direct relationship, but the battery should last longer if you charge it when it reaches 50% as opposed to 0% (that would qualify as "half" a discharge cycle).
When I'm using my device heavily and I have access to an outlet, I leave it plugged in. That saves on discharge cycles. Also, when I am sitting at my desk at work I generally keep it plugged in.
The following link is an excellent source of information regarding batteries:
http://batteryuniversity.com/learn/
right now with my current phone i'll usually just top it off after work from a wall outlet, or top it off in the morning when i wake up and get ready for work. i also have a usb cable at work to top off whenever needed throughout the day. i try to keep the battery over 50% most of the time, just because, but i rarely leave it plugged in throughout the entire night, and this is even with running sleep tracking apps. i imagine battery use/charging will be the same with the nexus 5 -- topping off in the morning while getting ready for work, maybe charge a bit while at work via usb cable, and topping off after work via wall outlet.
i guess i charge my battery in intervals throughout the day, instead of the daily 8 hour overnight charge. however, i usually keep it at least half full
Plug it in at night before I go to sleep.
If i'm using it heavily and it gets below 50%, I'll plug it in.
Some days at the office I'll plug it in about an hour before I leave so it'll be almost 100% after work.
If i'm going somewhere and feel I may run the battery down before I get home, I'll carry my portable charger with me (Anker 5600mAh).

Wouldn't heavy usage while its charging put too much heat on the battery? Which is worse for it then worrying about charge cycles?

It depends whether/how much heat is generated during heavy usage. On my N7 while browsing the net or watching videos the heat is non-existent. Certain games cause more heat than others. If the device starts to become "hot" then yeah, keeping it plugged in will only exacerbate the problem.
Also, having a case on the device can increase heat soak.
It depends on the situation.
You are right though that heat is the enemy when it comes to batteries. About an hour in my back-back on a beach on Oahu killed my GNex battery, and it was in the shade too.
I plug mine into a wall charger or my laptop...
At the end of the day though, if you don't bake or freeze your phone, the battery should last at least a couple of years without losing too much capacity I think.
The battery longevity discussion with mobile devices is similar to the oil change debate in automotive circles. Some people swear by certain brands and oil change intervals, whilst others just buy what is on sale and change the oil when the car tells them too. It probably makes very little difference in the end.

Smart alecks. Granted, I got a chuckle.
To OP:
Today's lithium ion batteries are way better than what they were 10 years ago. As posted above, go to battery university and learn all about it. My advice? Don't worry about special ways to charge your phone. You'll break, sell, or permanently store this phone long before your battery gives out due to charge cycles.

This!
Once upon a time I used to wait till my phone drained to 0-5% before I charged it. But I quickly realized that doing so turned my battery into trash.
So now with my 2 latest phones I usually charge it when they are at 30-40% or higher if possible and not only do I get excellent battery time but also its lifespan & performance doesn't deteriorate over time.

The only advice you need: DO NOT FULLY DISCHARGE LI-ION BATTERIES. These aren't NiCads, you do not need to power-cycle them periodically.
For best Li-ion life, try and avoid discharging below 20% or above 80%. Manufacturers will often add some 'headroom' to the 100% level (so that a battery that reads 100% is actually only charged to 80%-90% of capacity) in order to maximise longevity. within that range, charging and discharing will have little effect on battery life. charge and discharge rates do have an effect, but again ythe battery controller will limit these to prevent damage to the battery, so this is not something you need to worry about yourself.
Keep the battery topped up and avoid discharging it completely. Anything else is hocus-pocus or incorrect advice for the wrong battery chemistry.
i replace my phone once a year so i dont bother with saving the battery etc.. ive never had any measurable degradation to the battery the way i charge in less than a year. I usually charge it from what ever % its at to full. Most of the day at work it stays on my wireless charger, but it stops charging it after its full.
Thanks everyone for the feedback this far, in just a couple of minutes I already learned a lot.
Please let's continue the talk and vote if you can!
Thanks again.
On the charger before reaching 10%, around 20% or higher if it's possible.

Thanks to this two people.
Before i read this, me always charge the @ 10% or below.
+1 :good:
I just discharge to 20%-40%, then charge it with the included charger overnight...
I've tried using slow chargers but didn't really make the battery any better.
I agree that discharging it fully is bad. Very bad.
I just charge it how it's mean to be charged and I don't have any problems

I've been charging wrong this whole time! Will start charging before I hit 10% from now on. Glad I saw this, just got a new phone and am hoping to keep it for as long as possible...
I charge it every night because I have to use it all day.

normal charger

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.

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.

How To Guide How to extend your battery life (Xiaomi Scammed Us)

THROW YOUR 120W CHARGER AWAY.​
Get a charger for around 65W.​
Get a decently good brand. ( I'm using Anker, 65W Mi Charger is also good. )​
Anything below 30W would be too slow to charge your phone. Not really practical.​
Personally tested a 10W charger, did not work out for me as it doesn't give me the same battery performance.​
In my opinion, Xiaomi played us on this one. The 120W charger is a marketing gimmick. I don't think it charges the phone to 100% even though it shows 100%. Either that, or it messes with the battery calibration. As soon as I charge with a 65W charger, the battery goes back to performing properly. By that I mean, lasts me the entire day, and I still have 35-40% remaining the next day on medium usage like maps, streaming. On heavy usage, it still gives me great battery.
I'm 100% sure, you will notice the difference if you switch away from 120W charger as it will drastically extend the battery.
If you have already experienced the difference or made the switch, please do share your experience. On the stock xiaomi charger provided with the phone, the battery life is really terrible, the same usage gets me barely to the end of the day.
If you're still not satisfied by the drastic difference made by the charger only.

How to increase the battery life of the Xiaomi 11T / T Pro
Hello guys, I want to tell you about the adjustments that I have made to my Xiaomi 11T Pro and that have improved battery consumption, keeping the refresh rate of the screen at 120Hz. I would appreciate if you could tell me how it went...
forum.xda-developers.com
It will be simply because it is a fast charger, incredibly fast, and you can't completely charge lithium batteries fast, there is always a slow end stage that will take an hour or more regardless of how many watts the charger is. The last top off stage, or saturation stage on lithium cells needs by definition to take time and will charge at a lower current and it has to be slower.
They are showing 100% on fast charging, but that's only the bulk charge capacity with a lot of the saturation stage not done, so you don't get full capacity. The 100% indicator is saying you've charged as much as you can fast, but it might only be 70% actually full. If it is left on the charger, it will likely wait until the temperature has dropped then continue for an hour or so completing the saturation charge, all while still indicating charging is complete, but if you remove it from the charger the moment it hits 100%, then it's not the same 100% you'd get by leaving for a couple of hours.
If they indicated 100% correctly as being as charged as it can be, it will take 20 minutes on fast charge plus an hour or two for the saturation stage to be done, so doesn't quite sell as well!
Xiaomi are cheating somewhat by saying 0 to 100% in x time on fast charge, as the definition of 100% when fast charging is changed.
Personally I just charge over night at 5 watt, better for the battery and you get full capacity.

Great insight, they should have mentioned it in a different way instead of saying it's 100% charged. But then that ain't gonna earn them any bucks.
Are you getting a good battery life on 5W? As when i was using the 10W charger and use the phone at the same time it would take forever to charge. And the battery sot wasn't as good as well compared to 65W sot for similar usage.
I also use 10w (5v 2A) and can get for about 8h of sot, charging time is in my case takes about 2:20h from 17-100%Its not that bad, and i prefere slow charging time anyway, i only use 120w when in hurry

Are you getting a good battery life on 5W? As when i was using the 10W charger and use the phone at the same time it would take forever to charge. And the battery sot wasn't as good as well compared to 65W sot for similar usage.

If you are using the phone at the same time as charging, you are of course using a chunk of that 5 watts to power the phone, so whilst your battery may not be discharging, there isn't much left over to charge it up.
I always charge overnight as I easily get a day if not a few days from a single charge as I'm not using it much currently as working from home, but if you need to top up during the day whilst still perhaps using it, you would need a charger with a bit more wattage.
Also note that whilst it may say 100% charged, that could represent anywhere from say 95% to 100% actual charge. This is because lithium cells can not be trickle charged, so when charging it will get to being a full capacity, then charging stops, the battery is allowed to discharge several percent before automatically being topped up again, and the cycle continues. So depending on where in that cycle you take the phone of charge, you might be really at 100%, but could equally be at 95%. Because people would complain if the true charge status was shown, i.e. people leave the phone on charge all night and its still only showing 95% in the morning simply because it's on the discharge stage of the discharge/top up cycle when they look at it, they would complain, so 100% is shown from say anywhere between 95% and 100% of real charge state. This applies to all devices. It is why sometimes you take your phone of charge at 100% and it seems to stay at 100% for some time, and other times it starts going down soon after you've unplug it from the charger. Google on their Pixels have an adaptive battery setting and use the alarm clock you've set to know when you are getting up, so they make sure they time that cycle so that you get the phone at a real 100% capacity.
Good thread fellas. Yeah 120w it's just a thing you should use when there's not another option or your in a real rush. And by using it your battery calibration might get confused.
It's as the OP mentioned, with 120w you can feel that your battery life is shorter than charging with lower wattages.
IMO and experience I calibrated my phone's battery (drained it to 0 let it turn off , leave it unattended for around 10 min, then charge it with a 10w while still turned off if possible. And leave it charging 1h more after it says 100%) and b ayer doing so my 11t pro finally became the 2-day phone it should have been from day one.
I personally prefer to charge mine with a 18w (1h20min) or a 22.5w (1h) during the day. 10w it's just for overnight, it's just to long 2h40min or more.
This might be the reason why Samsung nor Apple has not yet jump into bandwagon of 100w-ish charging. Even not to 65w. It just my hunch though. Still, 100w-ish charging might be life changing in certain situation. And if I recall correctly, the most ideal percentage to charge Li-On is around 80-ish, that might the actual percentage that we get if we charge to 100% with 100w-ish charger.
To be honest i tried 33w charger and 120w charger and battery performance for me is the same(4.5sot + 6 background yt music)
The thing is when u use 120W charger and battery go 100% you have to let it charge 5-10 min more because is not fully charged.
You can check with app called ampere(download from playstore)

Please try a 65W charger from xiaomi or anker, i guarantee you the difference. Sot also depends on the usage, but there will surely be a drastic increase in the battery capacity.
And i completely agree to your point on trickle charging. But unfortunately, it does not justify the 4 hrs sot difference im getting after charging my phone through different chargers. 65W gives me 8 hours, whereas 120W full charge gives me around 4 hours.
I feel xiaomi really just did this as a marketing gimmick and did a half hazard job at it.

Like i previously mentioned as well in the above post, trickle charging or that 5-10% of charge shouldnt make the difference im experiencing after switching chargers. 4 hours sot difference is no joke. Its literally half battery capacity.
I love the phone, but Xiaomi really messed around with us on this.

Unfortunately i don't have a 65w charger :/
I get 4.5 sot because i also use yt music for 6-7 hours in background + 5g all dhe time.
The problem i noticed is that when i use my phone after charging my battery gives me good sot (5 hour non stop gaming mlbb and still have 25% left). But if i charge at night and use the phone the next day the battery drain really fast (that's why i charge every morning before i leave home).
I'm not really happy with battery life to be honest but im really happy with charging speed
+ How you guys get sot 8hrs?. I never couldn't do that with my phones( old device k20 pro average 5hrs sot)

Even after switching away from 120W charger, if you're not seeing a drastic difference, then i recommend changing the chargers to something similar to what i own (anker) about 65W or a mi charger 65W (official). Because i personally experienced the huge battery life change, and i know this phone can give a 1.5 day battery life on medium usage. On heavy usage it lasts me easily the entire day (8hours sot easy). But usage may vary. And when i was using 120W charger, it was giving me 4hours sot, with the same usage. So i know, the phone has the capacity to do it.
Maybe it could be a non branded charger issue? I'm not sure. It should show quick charging when charging via the different charger as well that way you know its getting the juice it requires.
Rocking a Xiaomi 67W charger and so far not much difference. I'm using the phone out of the box, I am not switching back to 60hz since whats the point of buying it if you wont use 120hz. Lets see after a few more cycles.
EDIT: After using this 67W for 2 days now, battery life is the same. IT might not be the charger but going back to 60 Hz might be the reason some ppl had improved battery life. I will return back to 120W since I prefer the ultra fast charging while the phone stays cool at the same time (mine is at 40-41 degrees C and it charges around 20 minutes)
EDIT 2: Tried 60hz for a day, since I was out with family, it noticeably improved battery life even though I charged with the 120W adapter. Hopefully Xiaomi adds a dynamicswitch feature for us soon or a 90hz option

I tried using my phone on 120hz for a day or two, i get like an hour less compared to 60hz i find a major difference in battery even with 120hz enabled.
Not sure why. But if it works, it works.
Also just to clear my experience, i never use this phone on 120hz, even when i initially was using the 120w charger. It has always been set to 60hz for me, as i like to save battery wherever i can.
Update: Using accubattery, when my phone reached 100%, its still taking in current around 1500-2000mah range (around 10-15w) and its trickle charging the battery. The estimated capacity when reaching 100% is around 2200 mah(times 2 since our phone is a dual cell battery) then letting it trickle charge for a few minutes (an extra 10) made the capacity to 2550(which is around 5100 mah) and by doing so I am easily getting 6-7 hr sot on 120HZ. It may be a marketing trick to reach 100% in an instant but leave it plugged in for an extra 10 mins or so to get more screen on time.
quite great battery life

Don't trust the apps. Find some real volt meter.

Amazing!
MIUI 13 by any chance?
I am on miui 13 official, had heavy battery drain on miui12.5, disabled miui optimizations and now everything is good
Edit: apparently the program that handles battery changed after disabling miui optimizations, maybe it's a bug related issue
