Hi, I just ran powercfg /batteryreport in CMD. The generated report states that after 30 charge cycles, my full charge capacity has dropped to 27,646mWh. the designed capacity is 31,502mWh, so my battery lost 12% of capacity in just 2 month!!
does your surface also suffer from serious battery capacity decrease? please run "powercfg /batteryreport" in non-elevated CMD and look at the report in C:\Users\*username* please post your result including full charge capacity and charge cycles.
Thanks!
mine is unchanged, reporting 16 cycles. I got the Surface 12/17 so I'm a week shy of two months myself.
I don't let my LiOn batteries deep cycle (drain down past 20%) if at all possible, as this reduces their lifespan.
Yeah my battery report says the same thing, even though I haven't noticed any lifespan decrease yet.
Mine has also dropped from 31,502 to 30,444 and 3 power cycles. Surely the battery can't be degrading already?!
At 34 cycles, mine has settled from 31.502 Wh to 30.214 Wh. It is very slowly losing capacity still (was at 30.740 for a few weeks in January) but seems to be mostly holding steady. The noticeable drops correspond to deep discharge cycles; I'll endeavour to avoid those.
Mines at 28472 with 38 charges. I got mine at launch 10/26/12. This is scaring me. Coincidentally I have noticed a decrease in battery life and was wondering if it had to do with the jailbreak as that is when I started noticing it.
47th cycle now, I still have 30,281mWh. I got my Surface RT at around 25th Dec.
29,415 after 47 cycles. Pre-ordered mine, arrived around launch date. This does seem very weird, batteries really shouldn't do that. Anyone have any experience with getting one replaced? Hopefully this isn't a problem Microsoft wont acknowledge.
cant seem to find my stats.. it only says mwh without numbers.. what the hell?
Mine seems to be worst here. After 24 cycle count, I'm down to 26,729. I do let the battery drain all the way - may be that's my problem.
I've had my Surface since Oct of last year.

That might be the issue perhaps, I have never allowed my battery to drain 100% or 100% charged for too long.
Mine is still at 30k range despite 49th cycle
I am extremely upset about this - in only 25 cycles, my battery capacity has gone from 31,502mWh down to 24,154mWh. And to top it off, I have been wondering why it seems the battery life isnt that good anymore. Is this permanent, or can you condition your battery by not allowing it to drain as much?
I have been letting it drain all the way down, and when i charge it, i plug it in overnight. Obviously this is the wrong way, WTF - you would think that they would tell you about this in manual, etc.
To be fair, this has been common knowledge for literally as long as laptops have been using Li-Ion batteries (well over a decade). I agree that it should perhaps be better documented for those who have somehow never before encountered a LiIon battery, but acting like this is some never-before-heard-of consequence of hard-draining your battery is... weird.
Leaving it plugged in all night is fine; the charger is pretty smart about handling that. Just try not to let the charge level drop below 10% (ideally, not below 20%, just for some safety margin) and you should be fine.

The charging system is smart enough to not overcharge, so you don't need to worry about this.
No one should be "reconditioning" or deep cycling batteries anymore - at least not if they are LiOn/LiPoly.
Got mine 11/4, 22 cycles, down to 25,xxx. Pretty disappointing considering I don't let it die all of the way. I'm hoping this is just an OS reading issue.

I turned off all low battery alerts and forced the battery to run completely dead, and recharged, and now mine has gone up a few points to 28,579 from 28472, with 39 charges, so I think it needs to be reset once in awhile. I however was not aware that leaving it to charge all night and using while plugged in could hurt the battery as others said - Still question that logic. I also have used it to the point of turning off but because Win8 has adjustible power options to force it to turn off when it reaches a certain battery level, I am not sure any of us run the battery down to nothing.
i just wish we could get a stupid battery ap/utility that would tell us battery life left in percentage or something to help us monitor it better.

Got mine on release, I've fully discharges mine about 3 or 4 time mistakenly, cycle count 49, full charge capacity 29,985, given this I've altered my battery plan to give a warning (low battery level) at 20% rather than 6% and to shut down (critical level) at 15% rather than 3%.
Oddly enough, my battery plan has never been adjusted so theoretically it should never drop below 3% yet my battery report clearly identifies it dropping to 1% at one point.
So, are you guys telling me that I should try letting it drain down to 0 and then recharging it to see if it is simply an issue with calibration?

What battery health does it report for you?
https://play.google.com/store/apps/details?id=com.digibites.accubattery
Had my Pixel 2 since Nov and tend to try and look after the battery with the now popular wisdom of not charging beyond about 80% when I don't need to. AccuBattery already now reporting 87% battery capacity (2362mAh total), even when benchmarking 0-100% charge. I can't recall what it reported when I first used AccuBattery - maybe mid 90's?
So perhaps I have a low capacity battery, or maybe AccuBattery should not be trusted anyway. Most users seem to get good and believable results from it. In use the Pixel's battery life seems reasonable and consistent with what many folk see, but we're only talking about a 13% margin and usage models and thus battery life change much more than that from person to person. It's just a 13% of extra capacity/life between charges that I'd quite like to have!
But how on earth do I prove reduced/poor battery capacity to get a RMA? I can't say "an app on the Play Store claimed XYZ". Phone was purchased from Google. Maybe I have to RMA based on some other fault I can cite that I can prove?!
Any ideas/experience of any of this?
I've had my pixel 1 for about 5 months (I got a warranty replacement because my previous battery would die in half a day), and AccuBattery shows my battery capacity health at 2087 mAH
My original Pixel 2 actually and genuinely stopped charging intermittently and I had no trouble getting it RMA'd. AccuBattery performs the same on the replacement.
I have now found with my Pixel 2 that AccuBattery under-reports capacity almost always whenever the phone is partially charged. It reports higher capacity when the phone is fully charged - the state it gets to beyond a reported 100% and when it actually stops charging. I put this down to a non-linear battery gauge on the phone - probably by design
I've had mine since October, never bothered with anything fussy like stopping charging at 80%, mostly used the supplied (fast) charger overnight (occasionally other chargers/power banks/USB). Today it's saying my capacity is 93%, but yesterday it was 89% and a few days ago it was 85%. The main thing I take from that is that it fluctuates by several % day to day.
Anyway I'd be amazed if they accepted 13% battery wear over 11 months usage as grounds for an RMA.
I asked this exact thing on Reddit and got nowhere. It's got to be some issue with pie and accubattery. All three of my pixel phones suddenly lost 15-25% battery capacity after pie. 2 pixel 2 and one og pixel XL. Right after a factory reset my pixel 2 shows 99% capacity and then slowly drains down after some charge drain cycles . Perviously it was always above 95%
Hello dear XDA members,
I bought Poco X3 NFC two days ago ( The Global version ) and I noticed that the battery performance is very poor.
At first I was using the screen @ 120 Hz frame rate and I was able to get 7 hours SOT normal usage, and 6 hours SOT while playing PUBG.
Then I changed the screen frame rate to 60 Hz but the situation didn't change... And I got 5 hours SOT only !
I would like to know if you are getting the same SOT?
Is it a general problem?
I'm on MIUI 12.0.4.0
I didn't get the chance to test the previous firmwares to compare screen SOT.
thanks in advance.
WOW, I have it set to 90 Hz and when I do not play, I get 11h SOT and over 40h on the battery.
Look
Same here. The sot. Is not good.
It will get better after one week or something

Yeah people either say it's insanely good or just plain garbo. I for example can't even tell lol. The built-in battery monitor doesn't seem to work properly. It spits out some nonsensical numbers and doesn't show all the apps I'm using. For example it shows 1,5h active for the display after 20+ hours of usage were I've watched multiple YouTube videos during this time (some of them longer than 20 minutes). And YouTube app doesn't even show up in the summary. Same goes for Opera browser which I use quite a lot. Didn't realise at first though, as I charge my device every other day or so and don't game much on it really (it significantly shortens the non removable battery life span). AccuBattery only shows estimates (free version). Don't know how they get an accurate/believable measurement with like 30h+ standby.

I heard of this issue too, and I started to use accubattery today to keep track of the battery usage
You need to calibrate your battery
Calibrate Battery:
Do two full charge / discharge cycles (from 100% to% 0, charge off to 100%) and finally a full charge (or half charge / discharge cycle, which is the same)
With that it would already be recalibrated.
Half cycle equals one full charge or one full discharge.
One cycle equals one full charge + one full discharge.
These are the so-called battery life cycles
Or charge / discharge cycles
Both terms refer to the same thing.
What kills lithium batteries are these cycles, it is like a flash memory, it has limited write cycles. Lithium batteries, the same, but both discharges and charges count.
That is why they recommend doing small charges and keeping the battery between 20% and 80%. Older people recommend carrying out a charge / discharge cycle every 15-20 days, to ensure the correct calibration of the battery.

So maybe it is the adaptive battery feature which takes some time to work correctly, I think I am getting a slight improvement.. still testing though
Battery Improved a lot since I wrote this thread, I think adaptive battery feature started to work.
My SOT is even worse than yours.
I am using poco x3 indian varient with 6000 mah battery
What did you do to increase SOT ?
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.

Sir can you please answer my last question?
That i have qutioned you in previous reply
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.

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.

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.

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%.

I just do it by eye. It's not rocket science.
Accubattery lets you set an alarm if you want.

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.

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.

Actually, the protection level should be 80% or less to maximize the battery’s useful life.

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.

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...

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!

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.
