My old phone's (Xperia S) battery drains very fast (can't last for a day) after 2 years of use. When it was new it lasted about one and a half day. I charged it every day for 2 years and the battery became weaker. I don't want this to happen with my Z2. I use dock for charging my Z2. USB cable or dock is better for the battery? And when should I charge it? wait while the battery drains full or charge it every day and don't let it drain, just about half, or don't charge it full and get it drained every day. And how long should I charge it? just that time while it charge full or leave it charging for longer (a whole night, about 10h)
someone please
I dont think it has anything to do with the way you are using to charge your phone... It's just natural for the battery to need to be replaced after a couple of years as far as i know
As far as I'm aware, after about 500 charge cycles the battery stops charging to full capacity (although it says it is). So the battery quality degrades over time regardless.
the battery of the Z2 is hardly affected by how you charge or how many times its charged
itll start degrading over time
it should be a Li-ion battery (referencing the packaging instructions for Z2)

yeah, I know that it's affected by how do I charge how many times, but I wanna know that what's the best for the battery

just charge normaly,
somehow i get the best life out of charging randomly, e.g. never 0>100% or simular but instead 20 to 60% increments gives me the best total life
in terms of wear, cant do anything with a Li-ion battery as far as i know
ok, better charge it when it gets as low as 30% and better not fully charge it, but 85-90% will be great for long term life. and never let it connected if it happened to reach 100%, also better keep it somewhere cold and definitely not under sunlight
It is said to live longer if you charge it from 50 to 90%.
That said, if you charge it from 0 to 100% every 2 days, or charge it from 50 to 90% ever day.... well... the end result is the same... it doesn't matter at all.
The battery already has safety over/undervoltage protection, therfore charching it as you like doesn't change much at all. You will see that a phone left at 100% in the charger will drop to 97-95% before it starts charging again.
i think the battery in the Z2 was said to handle about 600 cycles with less than 10% Battery degration.
if you charge it every 2 days thats about 3.5 years.
There is a lot of false information floating in this thread.(and lol Z2 deals with all, 10/10 loyalty) I was actually replying to this but I wanted a bigger audience to take better care of their battery, so check my thread out : http://forum.xda-developers.com/showpost.php?p=60299964&postcount=1
I really miss the option to turn off the fast charging (it is present on my Note 4, for example). I don't need the fast charging, because I charge the phone mostly at nights. And I'm almost sure, that the fast charging will degrade the battery more, than the regular charging.
The thing is, the Mate 10 isn't officially available in my country, so I will not be able to change the battery (don't really want to disassemble it myself).
What do you think, will it be preferable to use my Note 4 charger (Mate 10 should use it as a regular 5V/2A charger), or maybe the native Huawei charger may somehow be more friendly? Maybe, any recomendations?
Btw, did batteries get any better in the past 3-4 years? Can I expect the Mate 10's battery to degrade slower, than the Note 4's battery? (it degraded noticably in a year, even without a fast charging)

You can control battery degradation with accubattery on playstore. Very great app.
Better to charge to 80 % max in order to degrade battery slower.
App gives good advices et a lot of infos.
Moreover, yes, supercharger probably degrade battery a bit faster but I think it's negligible

Thanks, but I don't see it a handy solution, to be honest. I charge the phone at night, so I can't stop the charging at 80%.

We're automatizing anything we can, and you're suggesting to wait for a notification everytime I charge, to pull of the charging cable. Wrong or not, but I'll stick with the "plug in and forget" option, cause its really easier to disassemble the phone once in a 1.5-2 years and change the battery, than to wait it charging to 80% every other day So, the questions about the charger selection and battery improvements in past 3-4 years remain open

Ok as you want dude but honestly have a normal charger is useless..
Are there any studies that prove that fast charging can degrade the battery performance faster?
A shower and breakfast is all the time it takes to charge to 80%.

Speaking as an electronics engineer (and not as an expert on batteries), I'd suggest that "slow and steady" will always be kinder to the battery, no matter how much technological work has gone into preventing the battery from destroying itself through fast charging.
Keep the SuperCharge charger that came with your 'phone handy in case you need an emergency top-up, but for overnight charges use an el-cheapo 1A USB charger. It'll be more than enough to bring you to 100% by the morning, and there'll be no chance of crystallising/drying-out the battery's electrolyte.

You're probably right but science proves now that the most important thing in order to maintain battery is to charge it to 80 % max.
Your point is to be kinder to the battery right?
Better way is to charge it less than fully.
But, anyway, you're want to be stubborn ?. So, buy a normal charger, charge phone fully the night and don't cry after if you're battery doesn't work well.
And to answer to your "question" better is to buy a huawei charger if you don't want for sure any problem...
its not a good maner to compare note 4 with mate 10
samsung usually uses low quality batteries in cell phones
but after s6 and note 5 it improved the quality
about huawei's batteries
the batteries are in high quality state
my brother has huawei honor 3c lte. he bought it around of 5 years ago. after years we couldnt realize a significant weakness.
so dont worry about mate 10 and its super charge
im sure that your device will be working in a good condition
This is app is a must have and thought I'd share. Like everywhere I have read, they say battery should not be charged to 100%, it will hurt the battery somehow. This app "Battery Charge Limit" automatically (with root) stops charging the phone at whatever percent you want and starts charging back up at whatever percent you want. So you can always stop before it hits 100. It can be used without root but it only notifies you and you have to manually unplug the phone to stop charging. Better with root since its automatic.

Keep it turned off for a better batter longevity ??
Damn thos people are more preocupied of how to prevent the battery wear than actually enjoying this amazing phone
Well coming from an HTC device where after like what 6 months, my battery starts dying much quicker and hopefully this app and the nature of Samsung makes my phone battery last longer. Never owned a Samsung, so I don't know how the battery lasts over time.
This is a myth, modern phones already prevent damage from overcharging with the charge controller in the phone. Fast charging and slow charging also does not make a difference in battery longevity.
Just use your phone like a phone.
Yeah no
@nukeclears you need to bone up a bit more on battery chemistry before making statements like this. Overcharging is very different from charging to 80%. That's why Apple just implemented a charge limit in ios13 and Tesla strongly recommend charging to 80/90% max for daily use. Samsung just don't want to do this because they haven't felt enough pressure. I'll bet they implement it on the S11 and then for all phones by the end of the year.
Tab S4 has a setting to stop charging at 80%
You guys do need to go through all this? For what?
I have a Note 3 with battery since 2014 or 15, it still gives me the same power, sometimes it's better than it first was.
Charging fast/slow doesn't affect anything, I'm doing so for years.
I really don't think batteries die, if you felt it's weakening, just change OS, not the battery.
Samsung themselves, on the s10 series, suggest to charge from 30% to 80% everytime you need a charge.
In my daily usage, stopping charge to 90% is enough and I have all the juice i need till the next day.
If you are rooted, Battery Charge Limit app can be very useful to optimize the life of your battery (remember: battery is the first hardware component that ages your phone). On my 2015's Sony phone, they wanted me to pay 75 euros for battery replacement...
This thread is full of people who know nothing of batteries.
I bet your phone battery does "feel" the same after years when your os pushed that update that permanently limited your frequencys lmao.

Enjoy replacing it every year because phone batteries are becoming more commonly HARD GLUED into place. So go ahead, switch the whole phone out.
Hello, my Xiamoi Mi 9 is arriving end of next week and I am pretty hyped!
I am really not sure, if I do need these mentioned charging techniques. Apparently you can charge your phone from zero to 100 below one hour. Is it good to charge a phone very often and that fast? Doesn't it heavily influence the battery life? Shouldn't you just use a slow charger and charge it only up to 90%?

Well I don't think the charger influences battery lifespan, it's how you use the device that does
Most phone batteries are lithium ion batteries and honestly chargers (except fake ones) will not harm your battery regardless of charging speed, phones are built to handle them
If you continuously fast charge your battery, it will lower the lifespan of the battery over time. Unless you're planning to keep this phone for more than 4 years, it's not really that big of an issue. But charging speed does affect battery life.
What affects battery life is letting it go to 0% on Lithium. Just make sure you start recharging it around 10%-20% and you will make the battery last for a very long time.
I keep reading that you should try and just charge your phone to 80% to help keep the battery healthy, as going to 100% can shotren the life span of the battery.
How ciritcal is this?
I know letting your phone run down to 0% is bad as it takes a fully clylce then to get back too 100% and this is not good for the battery long ter, but i must confess i usually let my battery get to around 50/60% ish then charge back up to 100%
I've always charged my phones fully and never noticed any issues. Maybe if you plan on keeping a device for 10 years, but for the usual lifetime of a phone it's just fine. My OP7 is 2 and a half years old now and still has 86% battery health. I've seen others in Telegram groups say that they never charge to 100% and when they post their battery health it's not much different from mine, sometimes even less.
I think modern batteries are fine being fully charged ... otherwise the OEMs or battery manufacturers would limit them to 80 or 90% by default.

Hehe yea, I guess they all show 102% then because I have that as well
I like the adaptive charging, set up your bedtime and alarm for getting up (or turning over) After bedtime, phone gets trickle charged to achieve 100% at morning alarm. No excess heat etc. Phone then lasts me all day till bedtime when put on airplane mode, switch off Wi-Fi, & sleep. Works for me.
I'm showing 106%
I always charge to full, using adapting charging over night. Charging slowly and keeping temperature down is more important than keeping it to 80% from my understanding.
I just lay my phone on a slow charge Qi pad every night and when I get up it is at 100%. Nexus 6, Pixel 3, now Pixel 6. Perhaps my battery life went down a bit on my Pixel 3 after 3 years, but not enough to notice. I think 100% charge (at least slow charging) is safe for 3 to 5 years of battery life.
Li's like frequent midrange power cycling; it can extend the lifespan hundreds even thousands more full charge cycles.
Voltage and temperature are the Li's biggest stress factors. Low or high temperature charging can cause Li plating.
The higher the cell voltage, the faster it degrades.
The same is true with temperature.
Personally I just replace them every year or so as a failed Li can severely damage a phone. They tend to swell during a failure which can easily damage the display.
My Samsung S10+ is 27 months old now. I'm charging it to 80% mainly daily. Had maybe max 20 full charges and only once or twice to zero. I'm at 86% battery health (according to 146 sessions). Was 92% six months after buying brand new.
I think it helps. Also since the battery is OK (4100mah), dont need that extra 20%.
EDIT: 15W Samsung "fast" charging. As fast as that is ...

A Li is considered degraded when it reaches 80% of it's initial capacity. This signals the end of its useful service life.
Degraded Li's are more likely to fail.
Trust me it's better to replace it before it fails...
I think Better Battery Stats made that reco back in the day.
Charge to 80% and plug in at 10%.
Not so sure that really matters anymore though.
Both my 2 XL and Pixel 5 were plugged in before bed, unplugged when I got up, plugged back in when I hit 10-15% or when I went to bed.
If you plan on keeping your device for a long time (like 3-4 years) doing the unplug at 80% and plug in at 10% might make a diff.

10% is too low. It causes a lot of stress on the battery as it drops below 20% to charge from that starting point or lower.
Worse there's little usable energy after 20% because of the lower voltage. The phone uses the same wattage which is determined by V×A=W, so as the voltage drops it needs more milliamperes to make the same wattage. The discharge rate increases as the cell voltage drops.
A better low cut off is 30-40% or even higher and a high cutoff of 80% although 62% is optimum.
The Li likes frequent midrange power cycling. Charging beyond those parameters is for your convenience at the cost of battery lifespan.
Batteries are cheap and most are easy to replace... so I don't sweat it.
I expect a service life of 1-2 years on a heavily used N10+ battery.
However charging in the 40-72% range yields the most rapid fast charge in the shortest time so it makes sense to use this whenever convenient.
Well, I know things have been updated within Googles code itself.
"Adaptive Charging" / "Adatptive Connectivity" additions.
This was a real big problem for me with my HTC 10, (2016)
Battery degradation threads starting popping up.
I installed Accubattery after 1.5/2 years of owning the device and the battery was degraded to about 77% capacity at that time, IIRC. I was charging to 100% at that time, also.
So, I began charging stricly to 80%.
Compared to my HTC One M8 that to this day still has 90% capacity, and I used that device from the day Verizon released (3/2014) it until the day Verizon released the HTC 10 (5/2016).
I somehow managed to use the HTC 10 up until I bought the Pixel 5 on release day (10/2020).
I was charging the HTC 10 like 3 times a day just get through, and even went back to the HTC One M8 at one point because I had enough, but was waiting for the P5 to drop.
So to answer the question, I do believe it helps.
I do think that Adaptive charging/connectivity help, as well.
I take the view that if I don't need all the capacity on a particular day I charge no higher than 70%, which lands me around 30% end of day. Otherwise I'll guestimate what I need. Off to take some photo's tonight, so will probably charge it to 90% or so.
If you like fiddling around you can use something like Tasker to switch a smart plug that your charger's plugged into on and off at what you consider appropriate battery levels. Makes it all painless once set up. Or you can buy some extra hardware too. I use this in my car to limit the phone's max charge and temperature as, for me, I think most and fastest damage is done in a hot car float charging the phone at 100%.... https://chargie.org/ Not cheap but ok in my mind to hopefully extend the service life of the phone's battery. Less than the cost and hassle of replacing a battery anyway! (I'm not associated with Chargie other than as a customer)
OK, admittedly off-topic, but, this kind of sounds like a variation of the guidance I use for charging my electric car. Don't charge it unless it drops below 80% (so don't keep topping it up), but don't let it go below 20% regularly either. I mostly plug it in at around 60% and let it fully charge. Given the cost of a replacement battery would be more than the total value of the car, I hope this gives me 10 year of life.

EV metering is set up differently. What shows as 100% is likely a conservative 80% charge. Research for that variant.
A 35-40% low cut off is probably better as going lower generates more heat causing needless stress... unless you need that capacity.
Just downloaded the accubattery app and then fully charged but it’s estimating 6,401mah. Must be wrong and needs to calibrate over a few days.
I’ve never had any problems charging to 100% before so I’m not stopping now. I’ll be deleting this app if it keeps warning me like it has done.

battery drain
Hello, I'm using a pixel 6 with two cards sim. When I go to sleep the phone is fully charged and internet/wifi is turned off. When i wake up i have 88% battery (I lose 1,5% per hour). In battery use i see Ims Service. I did a test and in...
forum.xda-developers.com
I used to cycle from full to empty on my Pixel 2 before recharging, at about 3 years the battery couldnt last until lunch anymore. This meant more cycling, and I could fully discharge/recharge it 3 or 4 times a day. Within 6 months the battery only lasted 5 minutes, it was stuffed. Phone always hot and needed to stay on a charger 24/7, would turn off if I opened the camera without usb power connected.
Held out about 6 months on a permanent usb battery bank, was such a slog to wait until the Pixel 6 was released.
