Galaxy Tab getting better battery life than official specs?

Yes, according to this guy.
http://forum.androidcentral.com/galaxy-tab/44768-bettery-life-results.html
Anyone feel the same way?

its better than i expected, but i doubt its better than sammys tests

Same here it seem way better than I expected but I haven't tested the battery life thoroughly yet but indeed it is very good.

Tomorrow I will be flying back home. I'll be in the air for about 6 hours. I have 2 movies to watch, plus I'll be playing games and will listen to music. I am planning not to charge my tab until I get home. Let's see how it goes. I will update.

Being that my battery use is ~80% display, i should probably consider turning down the brightness. Still, I have been playing with it here and there throught the day (about 7 hours away from the charger now) and the battery level is still 75%
Somebody needs to find a way to mod the autobrightness to have a few options...I like the feature, but it is just a bit too dim for me.

My tab lost 10% battery for one hour medium usage (display on, 30% brightness, reading mainly). Dose it mean I have a battery issue here?

no. it just depends on what your doing. Wifi signal strength, Cell radio strength. the position of the moon and sun, etc.
BTW, battery life does not decrease linearly. so the numbers in that post are ridiculous.
the discharge curve will look something similar to this in most cases

(red line, also note phones cut off the extreme ends of the scale with regards to voltage to promote cell life)
it takes a few days for the battery (more specifically the charging circuitry) to get into a 'groove' when it comes to properly charging the battery and displaying the correct percentage.
if you want to know more about the Batteries in our phones and Tablets look at RCcar and RC plane sites. they use the same batteries as phones do so pretty much everything you learn there will apply here (except our phones don't draw 20+amps! )

Well, I understand you saying here. But 10% (90% to 80%) per hour for reading ebook only is far away from having a good battery at 4000mah. I will give it a few more days to check.

That's 10 hours at that usage, give or take, and right around what I'm seeing, 10% per hour of actual usage as an ebook, about 2-5% per hour if it's just sitting there connected, and about 15-20%/hour with heavy surfing or game playing.
I expect if I'm careful and keep the connectivity to a bare minimum, I can stretch 12 hours out of it when travelling.
Oh, and everyone...let the battery run down to zero at least once, preferably twice. We're talking total discharge to the point the phone turns itself off, then charge to 100%. This doesn't hurt or help the battery, but it does help make the actual battery monitoring more accurate.

honestly im not too impressed with the battery. i think the standby time sucks too. the iPad doesnt do a lot of things right, but the one thing it seems to do is to last for days. i realize the battery is close to twice as big but i was just use to that. i mean sure i dont use my ipad anymore, but it seems to last forever. anway, when i first got my tab, i managed to drain it in less than 6 hours. that was right out of the box (so it proly wasnt full all the way, but close to it). i was mad when that happened. that was with the brightness on auto and everything turned off except wifi. i could be just expecting too much. i thought conditioning the battery would be good for it. so i let it die all the way and recharged it to full. today, i wouldnt say i used the tablet like i usually would (i am a HEAVY user) and its been less than 12 hours and its already at 21%. this time it was running on 3G and brightness on low (not all the way, but about 30% or so). i dont even set the brightness to the highest cuz its too bright, auto seems to work the best. maybe im just being a tough critic. i mean my nexus only lasts like 5 hours now a days cuz i just use it too much. but im so use to just picking up another battery and moving along.

been having a good battery life after draining the battery to 3% twice then charging it to full again and now it almost last me 2 days better than my old nexus one using it primarily for comic book reading and bluetooth stereo music almost 6hrs. per day and a little gaming of angry birds and a little video and youtube + browsing calling and texting really don't like games too much
@croak
i've read a forum sometime ago that it's bad to drain li-ion to 0% so i think its better to drain it to near zero before charging again as i've read it may damage the cells if you drain it to 0%

how often should we condition the battery? (let it drain near 0 and charge up)

Doesn't hurt a lithium ion battery much at all, it's just another charge cycle.
But if you don't go down to the point that the device shuts off at least once, your battery meter can and often will be off by a good bit. There's never any confirmation. When yours was reading 3%, it might have actually been 8%, or it may have been 1% or less, but until you zero it out, you'll never know, and neither will the device. It'll still know when it's at 100%, but any reading below that can be inaccurate.
And keep in mind, this is NOT zero charge, it is not completely drained (the device does the auto-shutdown specifically to AVOID a complete drain).

Lithium Ion batteries don't need to be conditioned. But if you want to calibrate the battery meter, you'll need to do it at least once.

Using my Tab as a 3rd device, with my 1st being a HTC Evo and my 2nd being a Motorola i890, i am very impressed with the battery. Even treating my 1st and 2nd devices as red-headed step children and my Tab being in my hands more then them, my battery is yet to go below 50% in a day, the week i have had it. Even with checking 7 different email accounts every 5 min. Also, my Tab is on Wifi a majority of the day, which i would think puts more of a drain on the battery.
i was a little worried when i found out that the battery was not accessable to be able to swap it out at some point of the day. I have (6) batteries for my Evo, 2 red and 4 blacks. Before my tab, if my evo didnt touch a charger during the day, i would use atleast 4 of those batteries during the day. Yea, the size difference between the Evo and Tab battery is different, so i figured i wouldnt need 5 more Tab batteries, but atleast 1 or 2 extra.
My only complaint with regards to Power/Charging is the length of the USB Charge/Data cable. It is super short. i bought a 6ft extention @ Staples for about $5!
The fresh Tab battery is only spoiling us and will get worse as time goes by. I have been looking for other options in the mean time. Here are a few options i found:
ZAGGsparq 4000 mAh $90 @ fommy
Mophie - Juice Pack Powerstation 3600 mAh $99 @ BestBuy
ClearMax External Battery Pack 5000 mAh $39 @ eBay (questionable)
eGear UB-181 1800 mAh $19 @ eBay
eGear S220 (3-way charge: Solar,ac&usb) 2200 mAh $39 @ eBay
Yoobao YB-602 Power Bank (White or Black) 4800mAh $49 @ eBay
Personally, i think i am going with the Yoobao or Mophie or ZAGG.
***EDIT***
the ZAGGsparq is 6000 mAh, NOT 4000 like i stated above...

Yoobao has only 800 mA of output, too few !
Sent from my GT-P1000 using XDA App

The ZAGG has 2 x 1000 mAh. i wonder what the output is @ 1? I doubt very much that it is 1 x 2000 mAh...

Im impress with the batterry , way much better than my Ipad that I just sold ...

[How To] get 100% charge, overnight, lazily.

Many of you have read byrong's article on actual battery charge.
http://forum.xda-developers.com/showthread.php?t=871051
He discusses the creep down from 100% to 90% overnight; as well as bump charging.
I am offering a solution that will give you 100% (or over 100% if you so choose) every night without any effort after initial setup.
Lets first look at the charger:
Output:
5v
1000 mAh
So every hour, your charger could potentially flow 1000 mA into your battery, right? There's actually two contingencies:
How much can the battery pull, and the roll-off at the peak of the charge.

According to byrong's data, the last 10% charge rate rolls from 650 to 100mah in 45 minutes almost linearly. Prior to this roll-off, we are seeing 650 mAh pull from the battery which appears to be linear.
Ok now we can do our time calculation:
mAh of your battery: A = (1300 for stock)
Charge Rate: CR = (650)
10% roll-off: -(650-100)/(45/60) = -733 mAh/h (approx) Feel free to do the integral .1A/∫(650-733t)dt. Im just going to call it a flat +45 mins.
(A-A*.1)/CR + (45/60) = charge time in hours.
For stock, this is:
(1300 - (.1*1300))/650 + (45/60) = T (h)
T(h) = 2.55 hours. FROM ZERO CHARGE
I normally run down to about 30%. In that case... 1300*.3 = 390 -1300 = 910 mAh to charge
Run the calc again:
(910 - (.1*910))/650 + (45/60) = T (h)
T(h) (30%) = 2.01 Hours
Now what do we do with this?
Say hello to the appliance timer (you can get them at the dollar store):
http://www.amazon.com/50460-24-hour-Multi-Event-Appliance-Timer/dp/B000G1MD80
100% Charge Procedure:
Set ON 2 hours before you normally wake up.
Set OFF sometime prior to when you go to sleep.
You get:
100% charge every morning
If you oversleep, worst case scenario you end up with 90%.
BUMP Charge Procedure:
Set ON 3-4 hours before you normally wake up.
Set OFF 2 hours after that.
Set ON immediately after OFF,
Set OFF .5 hours after,
etc... until you've bumped to your desired level.
From now on just plug your phone in when you go to bed, and wake up to a 10% fresher battery every morning!
If you normally deplete your battery to a point where it will not make it until 2 hours before you wake up, consider setting your first OFF to 30 mins after you normally go to sleep.
ENJOY.
(+ Thnx if it helped you plz!)

After testing different batteries I have sort of a mini stockpile going on, so I'll be using this to bump charge my phone. Before it was just too much of a hassile to bump charge but this makes it easy

awesome, how many bumps do you normally do?

I thought that bump charging was bad for the battery. Is the slight increase in initial charge worth degrading the life of the battery? Any insight on how bad this actually is for the batter?

Bump charging while the phone is fully turned on has almost no affect because it doesn't truly bump charge- you're just keeping it at 100% instead of having your phone drain it down to ~90% and keeping it there. If you want to go over 100% you have to turn off Android (phone) and purely charge the battery, then if you unplug and do it again that's real bump charging.
If done regularly (with phone turned off) it can and will damage your battery degrading the overall lifespan. The benefit is you can end up with 105-115% normal battery capacity where when you turn on your phone, it will stay at 100% for hours.
But yea when I said bump charging before I meant with the phone on :s

Love the linked article and this walk through. My questions are do these timers(or the one you linked on Amazon) allow for multiple settings (like 4 different on/off times) or just one time for on and one time for off?
And I'm assuming the initial method is with your phone left on, bump charge with phone turned off? Since you are definitely the expert, which method do you prefer and why?

Almost all timers you can set an on/off time for half-hour increments- the digital ones you can probably be more specific.
Mine I set off/on 3 times right before I wake up.
Bump charging with your phone on will just keep your battery at 100%, since android by default keeps it around 90% if plugged in constantly (keeping a battery fully charged for extended periods of time is potentially damaging/ also reports of cheap batteries that are overcharged or on the charger too long exploding)
Bump charging with your phone off will overcharge your battery, this will cause some battery cells to die and lessen the amount of charge your battery can hold the next time you charge it. If you continue to do this then after 2-4+ months of bump charging, you may end up with a battery that will only bump charge as much as a normal charge used to be. This would be where you either buy a new battery or live with that fact.

Byrong calls bumpchargers 'power users' that will 'buy new batteries every few months.' So it really doesnt matter that your trashing your battery if you perceive the temporary life gain to outweigh the loss of longevity.
Most timers have "multiple events." You just set them using little plastic pins so it really doesn't cost them anything to give you a bunch of pins.
I personally leave my phone on, as it is my 2nd alarm clock. I have my inital off set to 2am (about 30 mins after my usual sleep time) to bring the battery up to the optimal 40% charge it should sit at. My on is set to 6am, 2 hours before i normally wake up. I do not bump, as i am not baller' $$$$$.

i thought if you charge you phone when its "off" you dont need to bump charge. I always charge mine at night and i will turn it on in the morning after boot i get 99% 2 min later after everything is done loading it still at 99% and i can get a whole day out of it. (stock battery) or if i run pandora for 11 hours (work 8 hours and commute 1.5 hours each way.) i will end up with 13%

Cool, Going to try tonight.

Well ya, charging your phone regularly with it off will get you 100%, but people like bump charging because you can overcharge the battery to 105-120%
Unless.. what you're saying is I don't need to 'bump charge' with my phone on when I can just normal charge with it off? And to that I say neh! I use mine as my main alarm clock and would like to be woken up if someone calls or texts me (most of the time anyway..)
For some or maybe even most people turning off your phone and charging might be the better choice.

I believe that even charging your phone with it off, will still allow it to creep down to 90% though yea? Those protect circuits are physically part of the battery.

beware of 'screen filter' app!!

This app called 'screen filter' is causing extremely battery drain through 'android os' even when i shutted it down when i finished.
Afret few hours the battery down to 1%. I afraid that i will have to buy a new battery. Why the phone dose not shut down when it gose below to 10%?

I've been using Screen Filter a lot for probably more than a year on different devices, including the Note. My Android OS is currently at 4 %. I'm not so sure this app is causing your drain.
The phone shuts itself off some time after reaching 1 % battery level.

I use screen filter daily and do not experience your issue. Check your other apps and be careful what you say about apps unless you are very sure.

Yeah, you should check what's draining your battery and stop scaring unsuspecting users. Screen filter isn't your problem. It works perfectly. Open Bbs and check for partial and kernel wakelocks to discover what's causing your issues.

Why the ??? should you keep your battery @ 7% and now buy a new one ?
Instead of believing everything you hear and read, go to school and learn physics
My note often runs at 1% and my battery still holds charge like new.
Just don't let it empty without recharging for a longer period.

Dude.. Basics of Li Ion Battery charging - to avoid memory effects in battery it is always advisable to let it runout to 1% & then recharge it to 100%.
This charging cycle ensures that your battery is performing at its peak.
Too many rechrages at intermediate levels like 30%, 50% etc reduces battery charge holding capacity.
So nothing is wrong with your battery...JUst recahrge it & enjoy.

There is nothing wrong with screen filter app. Have used it on multiple devices including note.

This is wrong information. The memory effect only occurs when not discharging the battery fully during the first five cycles. Current batteries do not have even this behavior anymore.
The effect you are noticing is just the battery calibration software in your phone isn't that precise anymore if you only discharge your phone to ~30%. It then tends towards loosing "battery percents" more quickly. It will remain powered on at 1% for a long time.

Li ion don't suffer memory effect, nor decharge/recharge cycle times.
They just have a limited lifetime from date of Manufacturing.
And as I said, don't leave them discharged for a longer period of time,
they don't like that

You're right, memory effect existed on NiMH batteries, Li-On's are not affected, in fact it's supposedly better for their life to avoid deep discharges:
Prolonging battery pack life wiki)
- Avoid deep discharge and instead charge more often between uses, the smaller the depth of discharge, the longer the battery will last.
- Avoid storing the battery in full discharged state. As the battery will self-discharge over time, its voltage will gradually lower, and when it is depleted below the low-voltage threshold (2.4 to 2.9 V/cell, depending on chemistry) it cannot be charged anymore because the protection circuit (a type of electronic fuse) disables it.
- Lithium-ion batteries should be kept cool; they may be stored in a refrigerator.
- The rate of degradation of Lithium-ion batteries is strongly temperature-dependent; they degrade much faster if stored or used at higher temperatures.

Also do not think that 1% reading on the display = deep discharge.

I actually had draining issues with my note, but after reseting the note fixed it. I had screen filter installed prior to the reset. Never installed it back like a couple other apps. . So cant really confirm what was causing this issue. The phone was always awake and did spent like 30% while i was sleeping...

Moral of the story... Do some research before blaming a program that your not even 100% sure is your issue... Oh and I use it and have had no problems with screen filter...

Have been using screen filter on my tab and note for over a year. NO battery drain.

I was knew to Android with the Note, and initially took the battery stats at face value. Over time I've noticed nearly all my problems are somewhat masked by logcat.
There is a slight delay when displaying the batt usage details and nearly all the time the 'app' that is reported as using all my battery life is the last thing that logged data to logcat (and is briefly displayed as logcat before displaying some other app name). In my case it is nearly always AVG that is reported as a battery hog. Further investigation with a log viewer normally yields a different culprit so look carefully at what is using your juice - it probably isn't Screen Filter!

official LG battery drain/degradation

I've had one battery since I bought my phone in August 2015
Over the past few weeks I began noticing much less standby and screen on time as before.....
I looked for any rogue apps that could be causing the drain...
I contemplated whether it was the new v20e and f updates..
I then got two official LG batteries from am Amazon seller for $15 (out it curiosity really)
Any now my battery drain is GONE.
I didn't realize I could have battery degradation so soon.... I've used the official charger for 8 months and a certified Qualcomm quick charger for the last 2 months
Not sure... But possible that I crossed 400 charge cycles on my original battery... As I use it as my primary smartphone and primary camera (mirrorless got relegated to the box)
Maybe the marshmallow battery drain is really decreased battery capacity?
Anyone else experience anything similar?
This also makes me wonder if phones like the Nexus 6p really have a shorter service life than I thought.
I hope LG keeps trying with what is now their exclusive feature of removable batteries. Not too impressed with the friend modules so far.... But I think I'll be buying the lg360 cam asap once it's compatible with my g4.

Same here!
Got the phone on May 2015. Battery life started to get worse with first MM update.
I used to get about 4-5 hours of screen-on time, now I get about 2-3 max.
Sometimes I need to recharge in the middle of the day(never happened before, even with moderately heavy use).
I'll get a new battery as well and post results, thanks for bringing up the issue OP

Battery life was good on lollipop. After the marshmallow update, started having significant drain. Did a factory reset, was slightly better. After analyzing for a bit, noticed massive GPS use, mostly in play services. Turned off location, and now use it only as needed. Giant increase in battery life.

I have no real battery issues with MM v20d, still on the original battery from June 2015.
Had the bootloop so MB replaced 506-->601.
After flashing v20f I started to experience battery drain (Android-system), it was caused by my Fitbit charge hr bluetooth connection.
Turning off bluetooth and only turning it on when I want to sync my Fitbit stopped the Android-system wakelocks.

Yes
Back to 1% drain on wifi overnight
And 4 hrs sot
I could see the battery percentage drop every few minutes of screen on with the original battery
So more that worth the $16 I paid for 2 new batteries
I really wasn't expecting to see a difference as my initial battery is now 10 months old

Not sure... But possible that I crossed 400 charge cycles on my original battery... As I use it as my primary smartphone and primary camera (mirrorless got relegated to the box)

Depends at which point you recharge.
ideally up to 90, back on at 40. Trying not to go below. With my 3+ yr old tab tab i've mostly followed that regime now and still can get almost 8h sot. 1500 cycles possible.
if you charge to 100 and then again at 5 & 10. Those are deep discharges which will decrease battery life sooner so around 300-500 cycles you see less battery life. (see table 2)
hey, it just might not be possible to do the former and this is why replaceable batteries are best.
This also makes me wonder if phones like the Nexus 6p really have a shorter service life than I thought.

There is a catch here, the 6P isn't the easiest of devices to service. it gets a ifixit score of 2 (!). So a battery replacement is going to be involved and cost appropriately.
I hope LG keeps trying with what is now their exclusive feature of removable batteries.

Definitely and the problem gets exacerbated with quick charge. Quick charge isn't good for batteries but everybody loves it.
QC 2 tries to get as much charge as it can up to a certain point then tapers off. Its more stressful than QC3 which tries to get as much as the phone will allow.Subtle difference.
It's possible with quick, fast, turbo whatever charge that people will require to change batteries sooner than in the past.

Just update to MM yesterday. My phone is just 2 days old so I have nothing weird to report about battery. Last night, I left my phone at 40%, after 5 hours of sleep, my batt is at 39%. So I guess this is a pretty good one. I also play games for 20 minutes and got 5% drain only.

Usually the battery drain after updating to mm is caused by fast dormancy.
U have to disable it.
Go to the hidden menu, type *#546368#*815# (replace 815 with ur model number, so 812 if u have the 812 model etc)
Then go to field test>Modem settings>PDP setting>0 and sellect fast dormancy off.
Reboot phone and you should be fine
This worked for me, try before u buy a new battery

Definitely we talking about battery degradation. Same usage, same condition, disabled MLT, Fast dormancy, etc etc etc... I am not new in Android world and LG phones. This is the result after first charging of my new battery. That was impossible with the old one. Result was 3h SOT and only 15% to 20% battery left on LP with the old battery. Now i have 3h 40 min SOT and 44% battery left. Usually i have 25 to 30 min SOT from 100% to 90%. Today from 100% to 90%= 1h 12 min SOT. If this is not improvement and proof for battery degradation...
PS: This is close or equal to my initial result, when the phone was new.

Could you send me a link to that battery that you have ordered?

This is original LG battery, which i bought from the store of the official LG importer in my country and unfortunately i can't provide you a link. I presume that on Ebay you can find original battery and may be cheaper than mine (25€).

G4 dual models are better than others i think , i usually get 4:30 hours SOT with wifi on and sync and one day standby on my H818N dual sim model.

This is the final result with the new battery after one charging cycle. Considering my usage and my results with the old battery, i am absolutely glad from my purchase.

Same here.
But do you happen to use a quick charger?
I used a quick charger for only 2 out of the 10 months that I had mine.... I'd like to think the quick degradation isn't due to that

I didn't use a quick charger even a single time, only charger from the box of the phone.
Overall... My device have two super weak spots: bootloop problem from the last week, and battery that lasts only 10 months...
Oh, and image retention/ burn in/ bla bla display...
D*mn, my experience with this phone it's not so good... [emoji1] [emoji1] [emoji1]

[HOW-TO] [GUIDE] - How to estimate the wear level of your battery

To estimate battery wear I use 3C Battery Monitor and Accu Battery.
In 3C app, you can find an estimation in the "Calibration" tab and in AccuBattery in the Charging tab (Battery Capacity Estimate at the end of the screen):
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
To benchmark your battery:
- Drain your battery to the lowest percentage without the device turning itself off. 5% might sufficient
- For more accurate results: Close all opened apps less 3C and AccuBattery and put the phone in Flight mode
- Plug in the charger and verify that both apps are running and counting mAh.
- Charge the battery completely. S7 displays 100% while the battery is not fully charged, you can verify this on AccuBattery's charging screen (charge status section) and in the notification, they'll display that the battery is still charging and charge current (in mA) is positive.
- Topping off the battery can take up to 1 hour on S7.
- Try not to use the phone while running a benchmark charge, measuring the current in mA is more accurate while there's no / low CPU load and variance in power usage.
Send your data !
The date since you have your S7, if you know, the number of charge cycles and the estimated capacity in mAh.
In my case:
Exynos G930F since the 4th of November 2016
A total of 80 charge cycles usually between 20 and 75%
I have an estimated capacity around 2700 mAh according to 3C and 2840 mAh according to AccuBattery.​

Nobody is interested in battery wear when it is non-removable in the S7?

Thank you for these tips, I will try it out tomorrow and post my results!
But is there a way to calibrate the battery in a better way then with apps like "Battery calibration"? I remember my first S7 (currently on my 2nd), It had amazing battery life unlike the one i have now which barely lasts trough a full day, and I dont have or use facebook/youtube etc.

To calibrate the battery gauge:
· Samsung support instructs to let the phone discharging until it gets off. Wait 1 to 2 hours and charge the phone without turning it on.
When the led goes green let it plugged for an additional two hours.
- To avoid getting the phone going off too early because of reaching the 3400 mV shut-down threshold (on high CPU load for example), I suggest to put the phone in flight mode and do not using it when battery reached 4 or 3%. Then let the phone turn off during the night.
- Do not apply this procedure to much as discharging your battery below 15% and charging it above 80% impact negatively battery life span.
· Some people says that using the BatteryStatus --> quick start also calibrate the battery. But I have not been able to confirm this with Samsung neither on forums.
To access BatteryStatus dial *#0228# on the phone dialer.
· A last option is to let the phone drains below 5% and charge until full and let it plugged for one hour after the led changes to green. For better results close all opened apps, do not use the phone, let the screen off and do it in flight mode. Making the benchmark I explained in my first post calibrate the battery gauge battery.
In my opinion, Apps to calibrate your battery are useless as they do not have access to the charging circuit. In the best case these apps lead you in the steps detailed above in the worst case is a scam looking for your personal data and delivering ads.

That being said, I do not think you have a battery calibration issue but an app that drain your battery.
Try GSAM Battery monitor to identify the app(s) that is draining your battery. Have a look to App usage.
I had a drain issue a few weeks ago. It was the samsung mail app that was draining my battery.

I have my S7 since 02/2016 - about one year.
Charged it from 0% to 100% until no more charge is pumped into the battery.
Accu Battery reports a capacity of 2289mAh from 3.000mAh
So about 31% wear. When the Device was new I also tested it and it reported slightly over 3000mAh.
I charge mostly wirelessly - normal wireless charging over night.
Fast wireless charging during the day at home or in my car.

Thank you for reporting your data!

Do you mean you always charge it from 0% to 100% or just for benchmarking purpose?

Why do you say 31% wear?
3000 - 2289 = 711
711 / 3000 = 23,7%
Aaah ! you caclutate it on 2289.

Just for benchmark of corse!
which calculation is the right one?

Awesome post, I was interested in my battery health a few weeks ago because by now I get barley 3 hours of screen on time (90% of the time I'm in airplane mode and have battery saver on). AccuBattery tells me I have 82% of my capacity left...
It makes sense thinking about how short the battery lasts now. I went from 7 hours sot in September to this :/
I will revert back to stock, maybe even flash the version from April to see if it helps, back then the battery was insane.

You are looking for the decrease regarding the initial value. So it has to be calculated on the 3000 mha.

Thanks for your comment.
On AccuBattery, on the discharging tab, which percentage is your S7 in deep sleep? Mine is usually between 80 and 90%. If you have a lower percentage, you might have an app that held awake your phone.
Are you using GSAM battery monitor to identify if any app in particular drain your battery?

It ist at 85%
Strangely I also noticed that I also have high standby drain. I just went from 100 to 90% with 8 minutes of screen on time. But in gsam battery I can't find anything strange other than the the high system usage but that was always like that.

I understand your are rooted. the only explanation I can see is the CPU scaling governor not set to interactive (you see this with Aida64 app)

I'm using kernel adiutor, unfortunately everything is already in interactive mode. I should really try setting up the phone from scratch, not rooting or do anything for a while to see how it goes xD

I have the S7 for 4 months now. Build date is August 2016. After aprox 76 charges I now have 89% battery capacity left. I did not use quick charge at all. Usually charge it in the evening evwry second day and rarely I leave it charging over night.

Thank you for this post. I tested my SG7 and it seems its now about 2735mAh , i have had it since almost day 1
Im running superman rom
i just drained the battery and its charging now

84% since day one. But i smell bull**** on these calculations. Sot is aproximately the same as when i bought the phone.
