I just learned that some laptops include a utility that offers to limit battery charging capacity to within 0–80% in order to slow the attenuation of the battery lifespan.
is this possible on Nexus 6P?

The charge rate is stepped down after 80 and to a crawl after 90% to prevent the battery from heating up. I think it's the heat that damages the battery and the charge rate regulation probably minimizes the problem.

Quoting from that document:
Most Li-ions charge to 4.20V/cell and every reduction in peak charge voltage of 0.10V/cell is said to double cycle life. For example, a lithium-ion cell charged to 4.20V/cell typically delivers 300–500 cycles. If charged to only 4.10V/cell, the life can be prolonged to 600–1,000 cycles; 4.00V/cell should deliver 1,200–2,000 and 3.90V/cell 2,400–4,000 cycles.

My Nexus 6P charges the cell to 4.40V! If the above can be extrapolated, that would mean that it would have lost 30% capacity after only 100 cycles!
What afdals (and yours truly) would like is a simple mechanism to stop the charging at e.g. 4.10V. That would result in a total capacity loss of about 10%, but an increase in life-span of a factor 8!
I think the question in the OP is well worth asking.
Can software stop the charging, or is it handled by hardware?
Amazing how this is all claimed, yet my nexus 5 has been charged every single day, from empty to full, since its release day... And I still get the EXACT same battery life as I did in the beginning.

Maybe you were just lucky. I saw the capacity of my Nexus 5 battery decrease markedly (although I must admit that I never measured the capacity properly.)
If you read the Battery University article(s) you will find that there is quite a lot of disparity between units.
Consider yourself one of the lucky winners in the lottery that is modern manufacturing!

But it's not entirely clear what battery chemistry we're talking about here. Is it a standard LiCoO₂ (Lithium Cobalt) battery? Huawei talk about some kind of carbon anode, which allows the battery to charge faster.
Does anyone have any information about this?
So to protect battery life, you want to effectively turn your 6P from having a 3430mAh battery to a 2744mAh battery and have 20% less battery life. Yup, seems legit.

Or just charge as normal like everyone else in the world, previous phone i have owned still hold their charge fine.
Always user the right turbo/fast charger supplied or use a slow charger 1A if you must get some charge or use a USB port, there is very likley built in protection on your official charger and or computer USB ports that takes into account over voltage or other strange goings on.
its highly likley the phones charging circuit allows the devices to charge to a set level and then trickle charges the rest the same goes fro the other end of the scale a Lithium iron batter does not like to be 100% discharged and causes issues over time and effects the life of the cells.
one would assume the 0% is the point where the charging circuit says OI stop drawing current from the battery im too low.
Typical batterys for such devices have a built in temprature sensor allowing the device to stop charging if the cells temp is above the prescribed limits, the charger that came with your device will have the right charge protection for the handset so you should always try and use the one that came with your device !
most batteries have under/over charge built in from any rereputable manufacture
so in all likleyhood if you where to not use the correct charger the battery would overheat and the temp proble would say im too hot and stop charging there and then untill your inside the limits again, hence leaving your phone on charge all week wont do any percevable damage and all those articles are ball****.
you could always have the protection fail or deliberatly manually charge using the + and - terminals on a lipo charger set to the incorrect values and watch it swell from escaping gasses and eventually catch fire / explode.

YES!
That's exactly what I want!
Instead of being able to draw 200 cycles of 3430mAh, I'd like to be able to draw 800 cycles of 2744mAh. It's a trade-off, but one that I'm willing to make.
I'm tired of buying a new phone (or battery) every year, and I'd like this one to last two years at least.

Look at Figure 5 in the document referred to above. At 4.35V the capacity is reduced to 50% after 200 cycles. And my Nexu6 6P tends to charge to 4.40V!
(I think 'Battery University' is a reliable source. I don't know much about lithium batteries, but what they say about other battery chemistries rhymes with my understanding thereof.)
Maybe the batteries in the 6P are a slightly different chemistry, but I have been unable to find any specifics about the battery, so I think we can assume that it's a fairly standard LiCoO₂ battery. Huawei talk about a special carbon anode that allows them to charge faster, but I don't think that has any intrinsic relevance to the aging problems.
I kept my Nexus 5 for two years, and would have kept it longer if the battery had lasted longer. It seems to me as if mobile phones are reaching a feature plateau, and I would like to keep my 6P for three years.

Maybe we're not looking at the same graph. The one I'm looking at has a green line corresponding to 4.35V, which shows a reduction in capacity from 1050mAh to about 450mAh after approximately 190 cycles.

Maybe. I'm always interested in better information. The page itself has been constantly updated (last update was last week).
I assume that they would have updated the charts if the underlying data had changed, but battery chemistry is not something that changes every day, even though the way it's used can change relatively quickly.
If you have access to better information - please contribute!

I'd look into the Elemental X Kernel - I haven't used the 6P version, but on the Nexus 5 and 7, Flar implemented a 'battery saver,' which stops the phone from charging at about 93%.

That means that there is an option (at least on N5/7) for software to influence the charging. I was worried that it would be done entirely by hardware.

I'd say it would be in the 6P as well - there'd be no reason for flar2 to remove the feature; the kernel is in the original dev section, if you wish to look at it.

I noticed that I was getting some really bad battery life with only average usage, so I figured that this might be in part due to it being turned on and activated at the store without first being charged. So last night I tried to go through the motions of recalibrating the battery, but there is no way to reset the stats. I finally got the battery down to about 5% and it hovered there for long over an hour with constant audio streaming and then later 3d gaming, so I know it is not reading the battery properly. I charge it all the way with the phone off overnight, and when I get up, it is reading 100% without the disconnect warning. I turn it on and I have been using it all day today, but I am having the same symptoms.
Is there a way to accurately recalibrate the battery sensor?
Having the same problems.
Same problem for me... I recharged my phone to 100% and did a factory reset today, hopefully that helps.

did anyone else try this and have success? I had my phone on 0% for a good long while the other day and it never shut off. There is definitely something wrong with the initial battery calibration for a lot of us.
trying this at the moment. will update when done.
It's a lithium-ion battery, guys... They don't have a memory effect. All calibrating it (as you all call it) is going to do is shorten the overall lifespan of the battery. You can argue all you want, but it only takes a little bit of research to learn all of this. People are too used to the days of nickel-metal hydride and nickel-cadmium batteries where calibration and training were necessary.
These batteries like to hold a charge and be full. They like top-offs and constant charging. If you can, charge your phone mid-day, but at least every night. Draining your battery - especially as regularly as some as you do to "calibrate" it - will only bring it closer to its eventual death.

Read the first post, got frustrated (a lot of Hero users had the same idea about discharging... poor people probably get awful battery life now), and posted my reply.
The EVO users might be on to something, but that behavior is more associated with a battery that has been let dormant forever. If you have an Xbox 360 (with play and charge kit) or PS3 with multiple controllers, you can test this. Most people use one controller and the extras don't get much play. When you try to charge it, it'll read full much before it is actually full and will die quickly, but if you continue to connect and disconnect the charger, it will keep trying to charge it and eventually will come back to life...
If this is the case with our Epics, I wonder if we're using old batteries... My manufacturing date on my battery is July 27, which means it probably sat around for a little over a month before it got used again. But that shouldn't be long enough to cause this problem.
Did anyone else have an almost-dead battery when they got it? My package said that the battery should have been fully charged, but it certainly wasn't. What is the manufacturing date on everyone else's battery?

The build date on my battery is 7-25-10, and it was really low when I got my phone. Of course, I had no clue because the battery icon in the upper right hand corner is horribly inaccurate lol. I have a feeling a lot of the July 2010 build batteries are defective in some way or another. There is a running thread on adroidcentral where people are posting their phone and battery build dates and what, if any, issues they are having.

Maybe I didn't word my post correctly, but I know about the Ni-Cd/Li-Ion difference, and I know that the Li-Ion's don't have memory, but I am talking about recalibrating the sensor to accurately report the battery life. I know that this prinicple works even if my explanation isn't accurate, because when I first switched to Darchstar's (may his name be praised) CyanogenMod Froyo port, the battery life was terrible; but when I applied the battery fix, the "recalibration", or whatever the proper word is, the battery life increased fivefold. That is what I want to achieve on the Epic, move that extra power which is found on the low end so it is accurately displayed on the scale (no, not physically move it, I just didn't know how else to say that). I'm going to try the Evo fix now and see how that works, but I hate the "Charging Complete" thing, because I woke up, and my phone was at 68% battery, so it just sat there plugged in but not recharging all night.
My battery manufacture date is August 12th, and when I got the phone, I didn't actually look at the real battery life, but the indicator was in the second stop, so it could have been anywhere in a wide range, since the first stop doesn't seem to occur until about 70%.

Your understanding is the same as mine. Tjhe old NiCads needed to be "conditioned" by deep discharge, but the Lithium Ions don't. However, our problem is not conditioning the physical battery, but calibrating the logic on the phone that calculates the battery status. It needs to learn what 0% and 100% look like to phone's sensors.
The sensors themselves, IIRC, are reading two physical properties: voltage and temperature. The calculated percentage is a function of these, but can vary with the state of a given battery unit.
So it is a good idea to do a deep-discharge cycle at the beginning, and maybe occasionally later, to calibrate this function. However, it is also true that a deep discharge is not healthy for the long-term battery life, so the procedure should be performed sparingly.

I had an all but dead battery when I picked up my first phone. I had many other problems with that phone and took it back for another. Unfortunately I kept the original battery. After numerous little problems with the phone, and poor charge times, I swapped the battery out for the one in the charger/battery kit I picked up. It was almost fully charged out of the box. I did a full charge on it, and all the little problems seem to have vanished. The date on the "bad" battery was 7/27/2010. I'm guessing there's a bunch of unreliable batteries out there, and they may be the cause behind other problems people are having.
Now if they can just come up with a fix for the WiFi config file corruption problem, I'm totally sold on this phone.
There is a thread on here that talks about calibrating the battery for an Evo and it did wonders for my phone. I don't have the link but here are the steps:
1. Phone is on. Charge untill told to unplug charger.
2. Unplug charger and turn off phone.
3. Plug in charger and charge until phone beeps (about 1-5 minutes)
4. Unplug charger and turn on phone
5. Charge to 100% again (1-5 minutes)
6. Unplug charger and reboot.
7. All done! Enjoy a new battery.
Before I did this "calibration", I was really feeling bummed that my battery didn't last. I followed a few other recommendations (dark screen, turn off unused services, etc) and I got 1.5 days and still had 10 percent left! This was using the device lightly to moderately. Try it but DO NOT RUN YOUR BATTERY ALL THE WAY DOWN! It's not good for these types of batteries even though there is a safety zone built in.

Well I just did it so we'll see how my battery is at work, it still sits at 98% I'm guessing the cells are not balanced.
I did the charge, power off, charge, power on sequence this morning about 5 times. I have the Battery Watcher widget installed, and I just now I charged it until it said it was fully charged and Battery Watcher said it was 97%. I powered off the Epic, and charged it until it said it was full, I powered it on and Battery Watcher said 91%. What's going on?? Is Battery Watcher inaccurate? Is the phone's way of determining how charged it is inaccurate?

Just topping the battery off, I thought this was funny, took it off charger, and put back on charger. and it still says fully charged + charging.. yeah.. I agree something wack with the sensor. This lasted for 4-5 mins.. then phone gave me pop up/vibrated.. (fully Charged!)
Yes, according to this guy.

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.

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.

(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! )

Mine can easily last and day and a half, very impressed with the battery
crazy talk said:
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

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 ...
For those unaware, there is an app (Battery Monitor Widget) that estimates your mAh based on the current sensor for any continuous charge over 50%, larger being better . It's a nice alternative to all the "what's your SOT / battery life" threads where everyone has different usage patterns, signal quality, brightness, etc. Though it's not the full story as variance in chips/screens can yield different power usage. Though you can also compare the % drain / hour in different situations.
https://play.google.com/store/apps/details?id=ccc71.bmw
Automatic mA retrieval seems to work fine (selects the S6/Note 4 method), and a recording interval of "Every minute while charging (accurate mAh calculation). After that, all you have to do is charge your phone when it gets low on battery and look at the calibration tab.
I've used it on other (used) phones and it seems to give somewhat realistic numbers, but never a new phone/battery. Anyone else's past experience with this is welcome. It's been quite helpful in buying 3rd party batteries and used phones as it's a real estimate.
Definitely important to have a baseline comparison with other identical devices so you can see what's normal and what's typical measurement error on each model.
It seems to work best if you don't use the phone at the same time, otherwise it underestimates. Overnight non-wireless charging works best. Basically, when you use the phone or charge wirelessly, more of that current goes to heat causing underestimates.
I'm only finding reasons for underestimating, so I'd still generally trust the highest couple calculations within the past month, unless the model just doesn't report current well.
FYI the phone actually pulls more current than a non-stock USB charger on load, so I had to let it charge to 2% after the phone turned off in order for it to survive boot-up.
My measurements after the first one are pretty consistent so far:

I think this app doesn't work properly with latest samsung smartphones.
I had two S6 edge+ that should have a 3000mah battery and the calculated mah was allways between 2400-2950mah.
Otherwise this app worked properly with my S4 or note pro..

There is one report that it's accurate for the S7 non edge
https://www.reddit.com/r/GalaxyS7/comments/4bmg3z/whats_your_battery_mah_calculation/
Did you use the phone during those 2400 estimates? Due to the variance it's probably best to believe the highest number, in which case your 2950 is quite accurate. I'll have to run mine again.
It's been quite helpful in buying 3rd party batteries and used phones as it's a real estimate.
I tried every setting with the s6 edge+ and allways charge the device from a minimum of 20-30% - 100%
This app was so inaccurate that i deinstalled it and since then i use only gsam battery monitor.
I don't need to know the exact battery capacity even if this app would calculate it right.
It makes me crazy because i allways thought my battery is faulty and it was one of some reasons for me to buy another s6 edge+ but there were the same results..

Definitely important to have a baseline comparison with other identical devices so you can see what's normal, sucks that you had to buy another one to get that. That's basically the point of this thread, to get a baseline and understand what's normal, but also find out when you get a faulty one that deviates from everyone else's.
I wouldn't call it inaccurate, you said yourself it measured 2950 out of 3000 mAh, it's just you didn't know how easily it can understimate under load and other conditions. It's actually an invaluable tool when buying 3rd party batteries and used phones to get an independent capacity test.
Take a look at this thread, #267.

If everyone in your model family gets the same variety of measurements you know you're fine. If everyone consistently gets a higher value, then you know you have a potentially weaker batter.
Not saying you do, but those measurements are what my wife's phone looks like who uses it all the time on the charger or has bad signal / high drain. When she doesn't, she gets a measurement close to the real capacity, that's why I said yours seems accurate as it has some measurements around 3000 mAh.
In addition, batteries loose capacity sitting on the shelf, so there's always the possibility of it coming with a lower than the full capacity
Ok, i never used it while charging but maybe it was because most of the time i charge wirelessly?

Ah yes good catch, that could be it. Also other things like the automatic updating of a bunch of apps, or some other strenuous synchronization. I was just reading this:
http://batteryuniversity.com/learn/article/what_is_the_c_rate
When discharging a battery with a battery analyzer capable of applying different C rates, a higher C rate will produce a lower capacity reading and vice versa. By discharging the 1Ah battery at the faster 2C-rate, or 2A, the battery should ideally deliver the full capacity in 30 minutes. The sum should be the same since the identical amount of energy is dispensed over a shorter time. In reality, internal losses turn some of the energy into heat and lower the resulting capacity to about 95 percent or less.

So basically, when you use the phone, more of that current goes to heat, and I think that's also true for wireless charging: both possibly underestimating the capacity.
Nevertheless, I'm only finding reasons for underestimating, so I'd still generally trust the highest couple calculations within the past month, or some models just doesn't report current well.
My measurements after the first one are pretty consistent so far:

So I've stopped caring about careful mearuements, use it on the charger, do shallow charges, and it actually still seems to be very consistent on my S7 Edge (my previous phones has estimates with larger variances).

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

Same situation here. Flashed 5.1, but still have max 3h SOT.
One first charge cycle with new LG battery
Will report back tomorrow maybe
Obvious difference already
GPS seems the issue for me
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

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.

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.

D*mn, my experience with this phone it's not so good... [emoji1] [emoji1] [emoji1]
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):

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.

Charged it from 0% to 100% until no more charge is pumped into the battery.

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

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.

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.
