I'm hoping some with battery monitoring app can shed some light on this. I get decent battery life, comparatively to what I'm reading on forums. In CPU-Z my battery is rated as "GOOD" which I'm assuming/hoping is the highest rating as my phone is only 1.5 months old. Out of curiosity I decided to try the AccuBattery app. The first test charge of 7% (my phone was at 93%), above the AccuBattery minimum of 5%, said that my estimated battery capacity was only 2450 mAh. It was correctly reporting the design capacity of 2700 mAh. I'm going to let the battery discharge more this time and try again... 9% wear seems impossible. Thoughts...including is there a recommended app that gives reliable battery wear/capacity data? 2-year old Dell laptop still only reports 2% wear.
It may be the software, including needing several charges to provide accurate data. (maybe). I just did a charge from 75% to 100% on a HTC One M8 with 2600 mAh battery and the results were almost the same (2400 mAh estimated true capacity).
What battery health does it report for you?

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%
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...

We'll agree to disagree on the applicability and merits of aggressive battery management on modern mobile devices. I am quite familiar with the arguments but have no stomach to rehash the details (which matter). Best wishes, mate.

Fair enough... the devil is in the details.
I'll see how my 10+ does. Lol I may end up tearing it down to replace the bloody charging port before the battery needs replacement
A battery replacement isn't the end of the world.
Cheers, mate.
Hi
I bought my phone 4 weeks ago . I am currently using Realme 8 pro.
In accubattery it shows i have 89% battery health. Is accubattery accurate?
It makes me concern why my battery sustaining so fast .

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.
I don't know about battery science. But can you tell me in short is it okay? . Or i should go to coutomer care?

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.

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
Ok - this is a weird one for my S22u SD so I'd appreciate some feedback. I use AccuBattery Pro to monitor my battery and pre-Jun update (AVF1) after every recharge cycle to 85% (protect battery option is enabled) AccuBattery would show estimated capacity between 4861-5015mAh. Except for one recharge cycle, I used the same recharger but estimated capacity was still very consistent after each session. Samsung advertises 4855mAh average actual capacity for the S22u's 5000mAh battery so all is good with my S22u so far.
I updated my S22u on 6/23 and after that the estimated capacity has been between 4394-4536mAh after each recharge! I noticed this immediately and started using a mixture of different rechargers (including Samsung rechargers) and they were all consistently lower. A couple of days ago I turned off the protect battery option and started to recharge to 100%. Still, the estimated capacity after each recharge was consistently ~500mAh lower than before the June update.
There has been no "event" whereas my S22u has overheated charging or not charging or anything else unusual that has happened other than the June uppdate. So why is my battery 500mAh lower in battery capacity (about 10%)?
Still scratching my head, today while recharging my phone I had a notification that my battery was 100% charged and I was only at 88% and still charging!! The notification was from the Android 12 system UI. The phone recharged to 100% successfully. Somethings not right!
I've attached my stats below for the 10 days prior and 10 days after the June update as per my Accubattery Pro. I would appreciate it if you have Accubattery to look into the history tab and check your estimated battery capacity for a few days before and after the June update to compare mine to. You can get to the capacity estimate via the History tab, scroll to a recharging session, touch that session which will take you to the Charging tab and then scroll down to the bottom of that screen.
Not sure if this is an issue with just my phone or it is a general issue.
PS - I have not experienced any loss of SOT to justify the 10% additional battery wear.
Accubattery is cr*p for battery capacity stats, just ignore and uninstall the app and enjoy your phone. If you are paranoid, install Device Info and you may get a better capacity reading. For me it says 4800 typical. All batteries are bound to degrade after over a year or so, but not so soon.
Hello everyone, I would like to ask for your kind help with this problem.
My Poco X3 PRO has a problem with its battery, when I see with No Gravity Kernel the battery data, when I flash the fastboot ROM it indicates 100% capacity and its battery has a long duration but after charging the device 5 times its Low capacity between 93% to 90%, specifically 4793 Mah, this reduces my battery life and it would be great if you help me to calibrate the battery and not end up causing the same error, best regards
No kernel can help with that. They just have different ways of displaying battery capacity.
Lost capacity on a battery is lost capacity, since the battery degrades a bit from regular use and charging. And using fast charging degrades the battery faster than regular 10 Watt charging.
Don't be too fooled with battery, use your phone same as normal ones.
