I have always charged my phones to 100%, this 85% thing is very new to me.
I've never heard about it before until I saw it in my S22 ULTRA.
What are the benefits of charging only to 85%? Does it last as much as with 100%?
Does it really recommended to charge it up to 85%? Im not an heavy user, but also I'm not changing my phone once a year, I'm changing it one time in 3-4 years.
Also, I tried to never charge my phone at night, and trying to catch the battery not lower than 10-15 percent to charge.
So basically, it bothers me a little bit in the eye to see that the phone is only about 85%, because that way basically the battery will run out much faster(significantly, yesterday 10% went down in 45 minutes, which means I'll lose 45 minutes from battery usage for nothing).
So, my question is, is it really worth it? Is there a significant difference between the two options? I'd love your help, thank you all!
The 85% is to protect and prolong the battery life. I agree that you will loose 15% of battery time if not charging to 100%. I charge to 100% and when battery is 10 - 15 I charge to full. I guess on the long run it's better for the battery to only charge to 85%, but I change phones every year or 2, so I'm not to worried about prolonging the battery life
Set low limit at 30-40%
Top limit of 72-85% is better.
Li's love frequent midrange power cycling.
Start charge temperature is important to prevent Li plating. Battery should be at least at 72F, 82-90F is better. Cool if charging temperature goes above 99F. Never charge in direct sunlight.
Never attempt to charge at 40F or lower
Avoid having the screen on while changing.
When using, turn phone off if battery temperature reaches 100F or cool it.
Replacing the battery isn't a big deal unless you don't do it on a timely basis. When an Li has reached 80% of it's original capacity it's reached the end of it's useful service life and is degraded.
Degraded Li's are more likely to fail which can heavily damage the phone. Any swelling is a failure replace immediately.
High voltage , temperature and current drain stress the battery. Other than avoiding low temperature charging and going to either low/high extreme voltage ranges constantly I wouldn't worry about it too much.
I now replace my heavily used Note 10+ battery every year or so to avoid another failure, routine maintenance. Batteries are cheap and relatively easy to replace.

So, I understand that it recommended to charge up to 85%? :-D
I searched on google to buy a S22 ultra battery that will keep in home until I need it, but couldn't find one.

If you can last to bedtime on an 85% charge then fine use that setting if you intend to keep the device for 3 years or longer.
If (like me) you need 100% charge to get through the day, continue charging to 100% and dont worry.
I have been using mobile phones for 25 years and I charge overnight as I sleep. I have NEVER had a battery failure or problems.
Life is short, enjoy your new phone
P.S. If you are worried about stressing the battery by charging to 100%, I suggest you also disable Fast-Charging as that is WORSE for a battery cell than 100% vs 85% iMHO.
I used to charge my Note 10+ to 100%, every day plug it while in my car or plug it to my laptop now and then. After 2 years of use battery health was 89%.
On my Lenovo laptop I stop charging at 60% as suggested by Lenovo vantage. Bull****. Battery lasts a lot less after one year. Almost the half.
Enjoy your gadgets and mobiles. Anyway after 2 years most of us get a new one.

how does one set low limit?
i have a smart plug i use for my charger, only on long enough to charge phone from 20% to 85% (battery setting limit enabled).
i usually charge at 30% to 85%.

Keeping a spare isn't a good plan as Li's start to degrade as soon as assembled. So after a year or more of sitting there it will have lost some of its initial capacity.
They should became easier in the future.
Any solution to modify the protect level?
"protect battery level 90%, 95% mod instead of 85%"
85% seem to be very short time of using
For anybody wanting to change the limit from 85% to lets say 90%, you can use the App called Galaxy Max Hz, you can find it on this forum : https://forum.xda-developers.com/t/...ods-qs-tiles-tasker-support-and-more.4404929/
One of the options is to change the battery charge limit, on the lock screen it will still say : "Charging stopped at 85%" even though the battery is at 90% as set in Galaxy Max Hz

85% is actually rather on the high side. Either correct the excessive battery drain or replace the battery. When an Li reaches 80% of its original capacity it's reached the end of its usable service life. It's degraded at that point. Degraded Li's are much more likely to fail. Any battery swelling is a failure.

I use the 60% protection on my Lenovo as they suggested and gess what, after 8 years my battery still works fine, and lasts for 2h/3h. I used my laptop every workday on heavy use, and it's the most cheap line, it cost me 300€ in 2015 (Lenovo G50-30 Celeron N2840). It's all day pluged, but when i need to use on battery it's fine!
So i realy think this battery protection works, and my S22 Ultra it's for last at least 5 years, and the 85% it's enough to run my workday.

Maybe. Depends on usage. On my N10+ which is heavily used with frequent charge cycling from 40-60% to 72 to 85% most times I get about 2 years out of a battery. Higher battery temperature shortens the lifespan as well. Fast charging is more stressful as is using the device right after a fast charge. High current drain while in use is also stressful; optimize the device to increase SOT and battery lifespan.
Frequent partial charge power cycling can extent the typical 200 full charge cycles to 800 or more. A partial charge is not a full charge cycle.
Start charge temperature matters.
It's an electrochemical reaction, heat is required for it to charge properly!
-//-
Never attempt to charge if near freezing
Fast charging will not engage if battery temperature is below about 55F to protect the battery.
Charging below 72F or above 103F can cause Li plating which will permanently degrade the cell.
Optimum start temperature is 82-90F, cutoff is 100-102F max. Cool if needed.
Regardless of service time replace the Li when it reaches 80% of its original capacity. At 80% it's reached the end of its service life and is considered degraded. Degraded Li's are more likely to fail
Any swelling is a failure and it can destroy the device. Battery replacement isn't hard or expensive. Just part of routine maintenance...

Here is a good article why it's recommended to not load the batt to 100%
How to maximize battery life: Charging habits and other tips
If you've ever wondered what the best way to charge your battery is, here are some scientifically proven tips for maximizing battery life.
www.androidauthority.com
Personally i just keep the load between 65% and around 20-30%. Only if i know that i will leave the house longer than 4 hours I do a 85% load or 100% if i want to film and take photos. But this rarely happens.

I noticed this on my old S4 as well. 99% took the longest to charge up to the next %. Anyone know why this is? My phone was charging at 99% for like 15 minutes. I also noticed that using the phone from 100-99% goes very quick :laugh:

This is perfectly normal. Think of it as inflating a balloon. The last 1% will be really hard and yet it will deflate as fast as the rest. It is not recommended to push that last 1% too often. Ideally you want to stay between 30-70%.

He is correct some say 20-80%, best example is Samsung laptops, mine had an option in the bios of topping charge of at 70% to prolong battery life.

I heard somewhere that is a solution so battery dont became overcharghed.
And what kills battery capacity is if it became static. There must be electricity flow trought battery to prolong it life time.
Your only supposed to charge your phone to no more then 70%?? First i heard. Never heard that before, Interesting.

I looked into the same thing last month.
https://discussions.apple.com/thread/4465051?tstart=0
When possible avoid frequent full discharges. Instead, charge the battery more often. There is no concern of battery's memory when applying unscheduled charges. A high residual charge before recharge is a benefit rather than a disadvantage for chemistry of Li-Pol battery on all iPads. The best way is to keep battery between 40% and 80% charged. After LiP battery of iPad is charged to 80% capacity it switches to trickle charging with a potential to cause plating of metallic lithium, a condition that renders the cells unstable. One more incentive to keep battery of iPad between 40-80% is the rate of the charge loss when gadget is not in use. The charge loss amounts up to 6% per year when battery is fully charged, but only 2% per year when it is half-charged. Nevertheless, short discharges with following recharges do not secure the regularly calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30-40 charges fixes this problem.
Hi Guys,
What is the best practice to charge our Note 20 to maintain good battery life?
I checked my charge cycle and it shows its 8 so far but I only have the phone for a few days now. And I guess 8 is not good as it says on Internet the battery life cycle is 400-500 charge cycles. So I want to avoid battery damage.
With this in mind:
1. Do we need to wait for phone to completely shut down because of battery and then recharge? Or its not good for the battery?
2. If the answer to previous question is "no" then when exactly we need to charge the battery to maintain good battery health? If, for example, the phone is on 30% and we recharge, how is it different from phone being on 80% and we recharge battery life-wise? And how this affects charge cycle and health?
3. Can we charge the phone as often as we want despite the battery level?
4. Can we leave the phone charged at all times (100%)
Just want to make sure I am using the most efficient method. Don't want my battery to die in a few months time.
Thanks!
Just change it whenever you want. No matter how you take care of the battery. With today's battery technology, you need a replacement after 2 years.
Best practice is never run your phone or any battery powered device past 25%. I know it's easy to do since we are on our device pretty much all day. Reason for this is because when charging the battery it needs to have resistance to charge correctly. Less resistance the less charge is given there for weakening the battery life and quality. I charge mine every night no matter what. Ive been doing this with all my Samsung phones and never had any issues. And last its OK to run the ballery down once a month to clean out old or bad charge voltage left behind.
Best to charge between 30-80%
Li's love small frequent charges ie 40 to 65%
As the cell voltage climbs so does the damage; try to avoid going above 80%.
Charging battery below 80° F can cause LI plating which permanently degrades the cell; try to avoid. Never charge when below freezing.
Try to avoid going over 100° F
High temperatures and battery voltage cause the most damage.
Between 5-20% has the lowest power density of the voltage curve, try to avoid using that range.
If discharged to 5%, recharge within a few days. If the cell voltage drops too low it will be useless. Generally this would take 2 months or more but don't chance it.
Use the 25 watt brick to charge, enable fast charging.
I’m curious about battery health as reported by Accubattery (I can’t find the battery health stat in the phone itself). I’ve had the 4a 5-6 days and the health is at 97% (3048/3140). Is that normal?
I had some issues with battery drain at first, getting around 4.5 hours (a few people here pointed out it’s likely due to it not being on wifi). But I did a factory reset and it seems to be doing better (now I’m on track for ~6).
I‘ve read battery health numbers aren’t super accurate so I imagine some fluctuation is normal. Just trying to verify whether I’ve lost 3% battery life in a week. Thanks!
I bought it a month ago. Holds at 104% for 3 weeks, and recently dropped sharply to 99%. I think you shouldn't believe the program
Li's like being use in their mid range; short midrange cycles/more frequent partial charges.
High cell voltage and high temperatures cause premature wear. Accubattery is encouraging this partial charge strategy although it's not necessary accurate.
Don't charge your battery to 100% very often.
80% is better, 64-70% is best.
Don't discharge past 20%, a low limit of 30-40% is best.
Never charge if battery is below 40F.
Avoid starting a charge if battery is below 72F whenever possible.
Low temp charging can cause Li plating which will permanently degrade the cell.
Avoid charging over 100F.
75-90F is best
Fast charging causes no harm.
cool thanks. accubattery went from 97% to 98% a few days later so I don't think it's super accurate. I've never had it say 100% on this new battery though so I'm worried it's a bit low but oh well. Thanks all.

First you need to set whatever is the actual capacity of the battery. Accubattery will use the capacity that the Android is reporting, typically 4170 for a 4300 ma battery in the Note 10+ case.
It's wrong; but Android is the culprit in this case.
Accubattery is a very useful apk. It adjustable alert when charged to X% is great. It also logs net power charging/discharging. I use it for battery temp too.
People expect too much out of it.
I doubt it's low, in fact it may well have a slightly higher than rated capacity. Take care of it and you can milk years out of it. Frequent midrange charges, and watch the heat.
If the phone battery temp when using gets into the high 90's, cool it down. I use a damp microfiber cloth or rag.
At a battery temp of 102F I screen off the device.

Info is misleading, outdated (overlooks recent battery refinements) and originally based on much larger packs used in laptops, etc. Mobile devices discharge frequently, rarely spending significant time at high charge levels. Laptops are often tethered to a desk and charger for extended periods.
While there's nothing amiss with avoiding extremes one should not feel compelled to carry around a damp microfiber cloth (lol) to cool the phone when it reaches body temp. Yep, battery capacity may drop 10% over the life of the device by not getting panties in a knot over thermals. It's just a phone ...

This has nothing to do with laptops although on my e6400 you can software disable battery charging at will.
The Li battery weakness is it's user. Any time it's taken to a full charge you are doing substantially more damage than a 64% top off. One full charge cycle vs >1/20% a full charge cycle.
That's a lot of lost life.
You'll get about 2 years out of it or less with your plan if you're a heavy user.
Rather inept management when you could get years more...

Not really. The value it uses is from the Android OS its self which is inaccurate and constant.
In my case it is 4100 mAh.
On my original 4300 mAh battery it was off by 200 mAh, on the replacement 300. Assuming the battery was as speced. It could have even been over the speced value.
Depending on the battery temperature and the charge range Accubatter's estimate can vary by 200 even 300 mAh.
Set it so it will read 100% by entering the value Accubattery thinks it sees when the battery is fully charged. It makes it easier and less dissettling to track
In the course of the battery's life you'll probably end up reloading and losing the data but for short term monitoring it's very useful.
It's logging history is great for quickly spotting excessive battery usage or slow charging. With those considerations in mind it's a useful tool that doesn't consume very battery it's self.
After the Pro version is active I firewall* block it as it is constantly in internet contact otherwise... I don't need that. If you disable Playstore or Google play Services it will revert back to the free version unless firewall blocked I disable the former two most of the time so there's that.
That's my biggest complaint about it.
*Karma Firewall, a great freeware apk that uses almost no battery
Sir in my case it showed accurate capacity of my battery.
When charged my phone first my phone had 99% battery health.
But 4 weeks later it says something 89 percent.

Really I doubt they would accept Accubattery's data.
When your SOT drops significantly and it's not because of excessive battery usage by apk(s), then you know you have a problem.
Heavily used phones will get about 1-2 years of usable battery life. I'll probably replace mine again at the 1 year mark.
If you want it to last longer only charge to 80-90%
Don't discharge below 30%
Li's like frequently midrange charge/discharge cycles. Frequent midrange partial charges prolong their life a lot.
Never charge if below 40°F
Do not charge below 72°F, 85-95F is the optimum start charge temperature.
Do not allow battery temperature to exceed 100F when charging, cool as needed.

When your SOT drops significantly and it's not because of excessive battery usage by apk(s), then you know you have a problem.
Heavily used phones will get about 1-2 years of usable battery life. I'll probably replace mine again at the 1 year mark.
If you want it to last longer only charge to 80-90%
Don't discharge below 30%
Li's like frequently midrange charge/discharge cycles. Frequent midrange partial charges prolong their life a lot.
Never charge if below 40°F
Do not charge below 72°F, 85-95F is the optimum start charge temperature.
Do not allow battery temperature to exceed 100F when charging, cool as needed.

One more question sir.
What is better for battery health charging 20 to 100% once or charging 20 to 80% twice in a day.

Sir can you please answer my last question?
That i have qutioned you in previous reply
So my 4a has been having fast battery drain since few months now. I remember it having very good battery life initially. However now it drains battery very fast.
This is also surprising since I keep brightness low due to me being sensitive to it.. and also keep the phone charged upto 80% capacity only as I read that it prolongs battery life.
One thing I could note is that the phone drains slower in the 80 - 100 % range if the phone gets fully charged occasionally.
Hence I have been suspecting the 'rapid' charging which is enabled by default on stock charger to be one cause.
Is there some way to enable slower charging like what happens in case of 'Adaptive charging' post 80% capacity? I hope that will lead to lesser wearing down of battery.
Don't use a compatible cable/charger and it'll change slowly. I don't think any PC I've connected to can do rapid charging, for example, and the cheap USB chargers I have definitely can't do it, only the one that came with the phone can do it.

It's more likely an app that drain your battery in background than your battery dying already. Quick charge and adaptive charge are made to not harm the battery.
Are you rooted? If yes, install Franco kernel manager app from playstore.
In first page you'll see your battery life estimation (from system) and clicking on live monitor go-to the processes tab.
Just like top cmd on Linux you'll see which process is active and how much cpu it use
For me as an exemple i realized that when I'm using YouTube music. The AdAway app goes crazy and drain my battery. And its something that's not shown on settings/battety tab.
Fast charging stresses the battery more than slow charging. That said I almost always fast charge. I expect 1-2 years of battery life on my N10+'s though.
Charging past 80% or discharging below 30% stresses the battery; Li's like frequent midrange power cycling.
Don't start charging below 72F, 82F or higher is best. High temp cut off is about 102F.
Never attempt to charge a battery colder than 40F!!!
Erratic fast charging is a sign of battery failure.
A rapid decline in capacity is another sign of a battery failure.
Any rear cover bulging ie battery swelling is a failure, replace asap.
Once a battery is below 80% of it's original capacity it's degraded and has reached the end of its service life, replace it.
Degraded Li's are more likely to fail which can easily destroy the phone.
If the phone is used heavily or is 2-3 years old, probably time to replace the battery. Just do it.
On most phones the cost is low.

Mine does rapid one only Thankfully connecting a usb to a socket board does non-rapid

Thanks for the response
Frankly don't have that much usage of my phone. Will give sometime to observing with non rapid charging. Will give this a try if that still persists.

Thanks for the response. That was insightful
UPDATE:
Started slow-er charging since few days now.. and I really feel that the battery performance has considerably improved
Also update to Android 12 since few days as well so not sure if that has a role to play though I don't think so

If it seems to work better... I don't see any difference on my N10+'s though. Run times are the same slow/fast charging.
Keep a close eye on it as erratic fast charging is a sign of battery failure... I have seen that
Are you going to limit your charge to 80% or do trust that 100% charges won't harm your battery?
There's well known science that backs charging your battery too high and often will degrade it's lifespan.
But there's also the argument that phones now have smart charging and similar to EVs when the phone hits 100% on its display the charge is still only really around 80% of true capacity.
There's no way manufacturers are sacrificing that much of our battery life with how much we all gripe about it.
I use AccuBattery with an 85% alarm. That seems to be good enough for me.
I'm trying to limit my charging. I rooted my P7P yesterday but haven't been able to get charging limits to work with AccA. I'm using the 2022-6-4 version of AccA right now. Does anyone know a working method to limit charging that is persistent? I'm not going to redo something with every reboot.

Try out putting chargingSwitch=(gcpm/constant_charge_current_max 4000000 0 --) in /data/adb/vr25/acc-data/config.txt
It's been rock solid for me on my Pixel 6 Pro. You might have to run acc and test the available switches, it could've changed with the Pixel 7.

What does this do? Limit the charge current to 4000 mA? I like learning what things do.
Which build of ACC are you using?

Same build of ACC as you, and yes the that is 4A, rhe number is in microamps. This only sets the max charging current initially, it will try to readjust so you need to also set the maxChargingCurrent to whatever you want but that variable is based on milliamps.
I use 600000 and 600 for 600mA on my Pixel 6 Pro and it is a slow and steady charge. Worked out good on drives because it would hold my battery steady during navigation and didn't generate a lot of heat.
I just charge the phone to 100%. Take it off and use it. Never in my life did a battery fail, extreme degrade or fail to charge. No apps needed to monitor the battery either. Charging a battery to only 80% makes absolutely no sense. Over charging a battery and number of charge cycles eventually kills batteries. You charge a battery to only 80% vs someone who charges to 100%, who is going to have more charge cycles after a year?

To each his own but I think you have the concept of a charge cycle wrong. The last 20% is more of a charge cycle than the first 80%.
Ultimately you are going to keep your phone for... how long?
I charged my Pixel 2XL to 100% probably the majority of the time. My battery life was still 'good enough' to last 2 days based on my average usage 4 years later when I bought the p6p. Which I traded in for the P7P 10 months later (not a year because of the debacle the p6p 512 release was with supply). I suspect barring significant problems cropping up the 7 is a solid 3 year phone for me albeit admittedly with only 24 hours of time with it.
Does charging at a lower speed (less heat) and not charging it to full help elongate the battery life and help reduce degradation? Without a doubt the science says yes.
But ultimately it's more important if you're going to keep your phone for a few years. If you're going to swap out every 3 years or less, I don't know that you'll notice much.
