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.

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.

I am wondering whether the charging methods make a difference to battery life?
How do you charge your battery, and also your initial charge from new?
This is the first phone I've had that I didn't leave the initial charge on all night 16 hours initial as recommended by most phone manufacturers, and I just took it off after a few hours when it was charged up. Do you think that affects the performance of the battery? I've never charged it for more than a few hours. The main reason I don't leave it on all night is because it gets really hot, so when it goes green light, it's done for me
Do any of you let it run out past the amber warning colour as a completely flat battery is probably better to charge?
All my other phones were left on charge all night, every night, but they weren't this type of phone.... and in truth, it makes no difference whatsoever to the battery. The Motos also needed charging every day
Stunning work guys, 56 views by people I can only assume own the Hero, and nobody wants to divulge their dirty secrets about battery charging... Thanks anyway
Just look around google for Li-ion recharging, there is plenty of resources to read up on when trying to keep battery life at a maximum.

I was wondering how many people just got the phone, and charged it 16 hours initially or couple of hours and go, and do they leave on all night despite it getting hot.
Not hard...
You should charge it until it is fully charged but not leave it on charge extensively - excess heat may cause the battery life to reduce (although I wouldn't know how much degradation this would cause). It is probably ok every once in a while to leave it on charge overnight, in theory the phone should have circuits to protect against overcharging it anyway. 2 hours is about right for a charge cycle. You should charge it when the phone advises to do so - 15% or less charge. The Lithium Ion battery will only recharge cycle effectively a minimum of 300 times but I would estimate conservatively that is the number of times you can recharge. 2 days between recharges would give you about 2 years life out of a battery. I recharge it every two days, and charge time is about 2 hours.
Yeh, I have to charge it every day though......... Never lasts longer. I just wondered if you were supposed to do the initial first charge overnight and whether it sets the standard for the length of time you get each day after that?
i guess every hero is different. longest i used my phone without charging is 2 days with moderate use.
before i charge my phone i kill all tasks in the background and clear my browser history. might not make a difference but to me it feels better to have a fresh phone after charge.
Is that with the task killer app, or is there another way?
I can't imagine mine ever lasting 2 days.....

I'm using TaskPanel as a taskiller...
when i got the hero the battery was ~half full. i charged it for about half an hour, but had to stop the charging before it was full.
the battery doesn't last longer than one day, although i play a lot with it (obviously). when i put it to the charger i try to let it charge fully up, and i noticed that the charging is stopped when the battery is full (you see the icon in the not.bar go back to normal green battery, and the phone cools down noticably after charging is completed). concerning this i have no problem to leave it plugged in overnight. checked last night, when NOT plugged in it takes 4% of battery for ~7 hours in airplane mode.
There seems to be a debate on this topic as to whether you should do a FULL drain on your battery and I wanted to know what people's thoughts were on this in this forum.
I've used my phone twice now to the point where it has auto powered down on it's own. I will then hit the 'Power' button to ensure that battery is truly at 0% (the capacitative buttons blink for a second to confirm that I've hit the power button but there is no more juice left to turn the phone on).
I will plug into the wall charger and allow it to charge for 4 hours (usually around 4 hours, I'll check back to see and hit the power button and the onscreen battery display will show 100% charged).
I will unplug my phone, power on and keep using until the phone fully drains and powers off on it's own again before repeating this cycle.
However, others have stated that this is NOT necessary for Lithium Ion battery and can actually damage the circuitry of the battery? I've always been under the impression that you need to do a complete & full battery drain for lithium ion batteries at least 3 -5 full cycles/times before the battery has been conditioned/optimized for capacity.
Maybe I'm wrong...after all I'm coming from a G1 and this practice helped my atrocious battery life on that dinosaur!
If this is wrong, when should I be plugging my phone back in to charge? When it gives me the first warning to charge in (battery level turns orange - I assume this about 20% battery left) or on the "critical" battery warning when the battery icon in the notification panel turns red (assuming this is about 10% battery left)?
from what I've read in the past, letting your phone drain completely down until it shuts itself off is not good for the battery. I could be wrong but thats what I've read

Yeah, I've heard both sides and I've conditioned my battery for the G1 because it seemed to drain faster if I plugged it into charge when there was 30% or so still left.
Well, I've done two complete cycles so I guess I'll just try recharging when it hits the red mark next time.
When you plug in to charge? Orange, red or whenever to top off?
i plug my phone in when i go to bed. I dont care what the battery is at. I also charge it while i'm at work so when I leave, its around 90-100%. My battery rarely reaches red.

LOL - that would prematurely killed my battery capacity on the G1! I went thru two batteries before I started draining all the way down. Made a difference between 4-6 hours and 6-10 hours.

But what're you getting on average for battery life and display on time then?

I do the exact same thing. First with my Captivate and now with the SGS2 and the battery life on my captivate held pretty much exactly the same charge for the entire 15 months I used it. The battery on this SGS2 seems to last about 150-175% of the Captivate battery under the same conditions. I just came back from a week on the road where I spent 9-12 hours a day away from a charger and was using my phone constantly all day long and would get back to the hotel room with 30-40% battery left. Considering I was listening to music, playing plants vs zombies and sending and reading push email constantly throughout the day I am very satisfied with the battery life on this phone. I've never done any kind of conditioning or special battery maintenance.

i stopped looking at my battery stats a long time ago. I'll peak in there once in a while but I dont really care what the stats show because I'm always around a charger. As long as I get through 12 hours or so without charging, i'm happy.
Some devices need a full drain cycle to properly calibrate the fuel gauge - ours does NOT.
Lithium ion batteries don't like deep discharging - in fact discharging them too much will permanently damage them (fortunately, all batteries sold to end users have built-in protection chips to prevent overdischarge - but do you REALLY want to rely on that chip?)
Similarly, they don't like charge being forced into them - so don't "bump charge". (Bump charging is removing and immediately reinserting the charger when the phone says charging is complete.)
For long-term storage, store them at around 50% capacity if not being used. LiIons that are stored at 100% charge lose capacity MUCH faster than ones stored at 50%.
A Li-Ion that has been sitting for a long time (months...) will develop a passivation layer that can be detrimental to performance - a few charge/discharge cycles will fix this. You don't need to do a full discharge/recharge - probably even from 90 to 70 and back up a few times should be fine.

what about short charging during the course of the day? For instance, while I'm at work, I like to plug it in for a bit and then use it off the charger. Then before I leave, I charge it again for a bit. Do you think thats okay to charge the phone for short ~1 hour bursts?
No, the battery itself doesn't do well with deep discharges, but every device with one has circuitry to manage this and keep it from happening. The phone will shut off before the battery reaches a critically low discharge state. Just as it will cease charging before it blows up. Just because the phone shuts off does not mean that the battery is too low.
Assuming the phone has the proper cutoffs, it's not really any different to do two discharges to 50% or one to 100%. There have been studies that say leaving it on a charger is bad, doing two 50% cycles is worse than one 100%, etc. I've always just trusted that the phone manufacturers design the battery monitor and control circuits correctly and not worry much about it. And I've never had to replace a battery yet and always get acceptable life.
It's lithium ion, not nickel cadmium.
Full drains are bad for lithium ion.

lithium ion batteries dont like being under 30%. and they also dont do well if they are kept at 80 percent or above all the time. for longest battery life don't just let it sit on the charger all day after it fully charges.
I agree with Mikey here.
Also, batteries take charging current better (less wear) at lower states of charge. That's why I put a variable-current charging algorithm into my Infuse kernels (charginghacks branch on github)
800 mA at low voltages (200 above stock), dropping to 550 near the end (50 below stock).
Unfortunately, charginghacks is likely not going to be possible with our hardware. One of the differences between the I9100 and I777 is a different battery charger circuit - ours is far less flexible.

Infuse would charge with the screen on - but not if the screen was on AND the CPU was cranking.
(worst-case was navigation at full brightness - and I've seen reports that the I9100 also has the same problem.)

When web browsing, playing a game, or other general use late at night I'd plug the Infuse into the charger. It would still drain. Doing the same on the SGS II and it at the very least maintains it's battery level, so it's a drastic improvement over the Infuse.
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)

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
Hey, just wanted to let you guys(and gals) know that this app works perfectly on our axons: Battery Charge Limit.
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002
It does exactly as the name suggests, stops the battery from charging beyond a certain percentage, thus for example if you set a limit of 80%, your battery will preserve its health for around 1500 cycles instead of 500 cycles of charging to 100% before degrading by ~20% of its total capacity.
Enjoy the app guys, tested on B19, stock kernel, rooted.
So the way to have 1500 cycles is to only use 70% of battery at best. Because going under 10% is not exactly good for the battery either. I don't want to have an even worse battery life, so I think I'll pass, thanks though!

Don't go under 90ish as you will stop charging whilst quick charging and will damage the battery even more than if you didn't use the mod so just be carefull

Hey, just wanted to let you guys(and gals) know that this app works perfectly on our axons: Battery Charge Limit.
https://forum.xda-developers.com/android/apps-games/root-battery-charge-limit-t3557002
It does exactly as the name suggests, stops the battery from charging beyond a certain percentage, thus for example if you set a limit of 80%, your battery will preserve its health for around 1500 cycles instead of 500 cycles of charging to 100% before degrading by ~20% of its total capacity.
Enjoy the app guys, tested on B19, stock kernel, rooted.

Dont let them fool you, you dont need this app. The charging controller of your phone actually already has its safety margin built in. Same on the low end. This means you can not charge your phone to its physical maximum anyway, it will show 100% whipe the physical charge in fact is ~95% and will shutdown showing 0% while physically there is still about 10% of power left. So your battery is safe from this kind of damage anyway.
If you want to extend your batterys lifetime for real, try to charge it as often as you can, keep the charge as high as possible. Flat charging is the magic word. This is what your charging controller does when your phone is connected to ps for longer when it shows 100%, it in fact lets it deplate 2% without showing and then charges it back, thats called trickle charging and is the best treatment practice for our bateries.

Samdung pretty much confirmed they do this (or better) in the S8 and later (and possibly the S7). But has any other company confirmed they have battery longevity tactics built in?
Personally I use AccuBattery since I've had it for a long time as a charge alarm/monitoring tool. I use a 1 amp charger instead of the 3 amp charger that comes with it and charge my phone at low amps and voltage which prevents the battery from heating up. So low charge, low heat. I don't want a degraded battery in a year because I don't know when I'm replacing this thing.

What's you battery health percentage/capacity now? and for how long did u have your phone? Do you charge from 0-100 daily?

AccuBattery is no good for giving an accurate estimate of the actual capacity when you're charging at low %s. For first 50% it'll calculate something like 3500mAH+, for the last 50% it'll estimate 2000 or lower. If I had to give you a rough estimate of what I actually think it's at, it's roughly 2900-3000mAH. When I first got it, I estimate it was around 3100-3200 a year ago. I HATE that phones no longer have replaceable batteries. That's half the reason I wanted an LG V20, I could just murder the battery and just pop in a new one every year. Sadly the V30 is sealed, following the BS trend of planned obsolescence. Thanks Apple.
Oh and I almost forgot, I typically charge my phone from 20% to 50% after it drops 30%. Then sometimes once more if I use it some more. On average I charge about 50% worth a day without going over 50%. Even with such light battery usage, keeping the battery 30C or lower 99% of time, and keeping the voltage below 4.1 again 99%, it's still degraded at least roughly 200mAH in a year. Rarely when I know I'll need longer battery life I charge it to 80%. It's a cheap quality battery. ZTE cut corners. This was my first, and unless I have no other reasonable options, it'll likely be my last ZTE phone.

can you TL;DR this for me?
-So i better keep charge between 20% and 80% yes?
my old sony phone form 2011 still works nicely, as it had Quality battery (over 2000 cycles already) yeah does not last long 2/3 but still. useable.
And i agree, replaceable batteries is must have function, My old S3 and S4 worked for "ever" because of that, every year new battery and another year of usage! (s3 still going strong since 2012 !!! )

Apple has been using enclosed batteries for like 10 years or so.
You can do better than the app by setting a lower maximum voltage on the Axon 7 instead. I posted about the discovery awhile back on that thread https://forum.xda-developers.com/showpost.php?p=74746734&postcount=1353

Essentially, yes, that's what I keep hearing whenever I dig for information. If any of the stats of AccuBattery are accurate at all then it also supports that going over 80% causes multiple times the degradation that charging up to just 80% would. These days I try not to go over 70% based on app estimates of degradation. These days I need more than the 50% I was previously charging to.
Hi
I use my V30 as Hotspot the whole day and this sucks battery quite quick. Is it problematic if I keep the power cord (usb-power-plug) connected all day long? Does the phone still use the battery in that case or does it just draw its power from the power cord and only recharge the battery if it drops volatge by self discharge...

I'm not sure I believe that site... I have been a fan of Battery University, but in my experience they got this wrong. My Droid Turbo battery lasted for 4 years before I switched to the V30. I always charged it and left it charging overnight. My laptop that I'm typing this on now, has the original battery from 8 years ago, and it's still working. This laptop stays plugged in almost all the time. Certainly, it doesn't have the life that it would if it was new, but it's been 8 YEARS.
In my case, I keep my devices pretty long, and it doesn't cause a problem. So, I won't bother to unplug at night... it's not worth the hassle. Most people would upgrade their hardware well before these times, so they would notice the problem even less than I do.
The bigger issue I see is when it the phone overheats. My work phone (in my crappy work car) sits on a mount on the vent, which (because of the crappy car) doesn't close completely. So, this winter, it got very hot relatively often. That has hurt the battery life on that phone (a Turbo2)... which now has much less life than my Turbo does. But, it's a company phone, so they're going to replace it... not my problem
The other issue I see is charge cycles. My wife's laptop was often charged, then run on battery, then charged, etc. The battery on that laptop was only about 3 years old when it stopped performing (wouldn't even run the laptop for more than 10 minutes). IMO, charge cycles are, therefore, more important as than overnight charging.
Just my $0.02... feel free to disagree if you want.
Exactly! Charge cycles!
I only charge my V30 every 2nd or 3rd night for that reason, and I still get 7-10 hours SOT after 1.5 years, depending on how much music I play in addition to the SOT.
That said, it's also best to avoid draining the battery too low. The chemistry suffers the most when it's very low or very high.
Keep in mind, with charge cycles, they say it's proportional as well. So, if you charge 25% for 3 days in a row, it's the same as charging 75% every third day. I prefer to keep the phone charged as much as possible, in general.
Also, I neglected to mention, my overnight charger is a slow one (not a QC one). That way, it's slow charging overnight anyway. This speaks to the heat cycling of the battery - QC does heat it up more than a slow charger would. That's also why I don't wireless-charge, as it adds to the heat, too (at least it did on my older phones)...
