what is battery health in battery doctor app. mean?? and if it says good health it means excellent or 75% ? and can any one know method to know how many times my battery last rechange ang discharge at full capacity?
Is there a tool that reliably indicates the health of the battery in a rooted nexus 5?
I have Gsam battery monitor which is excellent at telling me what is using the battery, but how can I tell if the battery is getting old and needs to be replaced? Just timing how long it lasts has too many variables. Is there a tool that can check the battery health?
Dial *#*#4636#*#* on the phone.
AccuBattery estimates how many mahs your battery still has.
I guess it just interpolates charging current and battery voltage over time.
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).
Hello,
Sometime ago I started to notice battery in my S7 is much weaker than at the beginning. I checked how it works with cleaned system but effect was very similar. Then I installed two apps to check battery wear:
-Samsung Phone INFO: https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo
-AccuBattery: https://play.google.com/store/apps/details?id=com.digibites.accubattery
Effect was very similar: according to Phone INFO battery had around 370 charging cycles and it had 76% of new battery capacity. For me this wear wasn't normal. Battery was replaced under warranty.
Now I monitor battery again. Phone INFO noticed 12 charging cycles (AccuBattery shows 28 cycles because it also notices charging between 40-80%) and wear is similar in both apps: 95% left.
I wonder if you would be able to check battery wear in your S7 mobiles and let me know how it looks in this thread? My warranty expires in 2 months and if there is anything wrong with motherboard rather than battery itself I would try to sort it out.
In app https://play.google.com/store/apps/details?id=org.vndnguyen.phoneinfo there is tab Personal and there are two important for me fileds: "Battery Discharge Cycles" and "Battery Health"
Thank you in advance
My 2-years old S7:
Cycles: 513
Health: 84.7
Results from AccuBattery
Mine, after 2years and 2 months:
2.353mAh average.
I assume that would be 78% health. (2353/3000mAh)
EDIT: Where can I see my charge cycles? I will post them when i find them.

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.
