Supposedly... The battery on our Google Nexus 6 has a capacity of 3220 mAh.
Specs
BATTERY Non-removable Li-Po 3220 mAh battery
Stand-by Up to 330 h
Talk time Up to 24 h
I purchased a current, voltage, detection tool http://www.amazon.ca/gp/product/B00NNGK4QS?psc=1&redirect=true&ref_=oh_aui_detailpage_o05_s00
made by SainSonic.
Okay, I know this isn't a fluke meter quality and standard, but how come when I charge my phone from i.e. 20% battery capacity left, to reach a full charge the Sainsonic USB tool reports back with a supplied mAH of approximately 1500mah to reach a 100% charge.
Are we to assume the battery capacity supplied by motorola for the Nexus 6 phone to be rigged or false? Is this another one of those cases, where your mileage will vary b.s.
I know the USB detection tool is not a Mil Spec device, but, how can it report back this off of factual value or reading?

2nd test
OK, so I let the phone on, til the phone did it's own shut down. I even rebooted the phone into Recovery mode, where it eventually powered off, 2x. I know this is bad and not recommended for a battery, but I wanted to try to deplete the battery completely, and using the turbo charger, charge the phone and get a mAH consumption to refill the battery.
From an empty charge to maximum, I recorded 1825mAH. I am unsure, if by TURBO charging the phone, whether I am not registering a true milliamp draw and count. My last test, will take place doing the same thing, but using a standard NON turbo charger to see whether or not this reports a difference or not.
Cheers
That meter does say that it's for between 3 and 7 volts which is pretty much saying it's made for a standard 5V usb spec current. The turbo charger uses voltages of 12, 9 and 5 volts to accomplish its faster charging speed and the charging voltage only goes down to 5V once the battery is almost full somewhere like 75% iirc.
Though it also wouldn't surprise me if the turbo charger doesn't turbo charge when running through that meter. Might check and see if the phone charges any slower when you switch to the normal charger test.
While Charging, the USB meter does show it's outputting voltage as well. AND, while charging I do have the phone using an app like Ampere so I do see that it is in fact indicating TURBO mode. But logically, the phone does complete it's charger in under 2 hours, hence it is charging very quickly = same as turbo charging.
1) It is in fact Turbo Charging. 2) The outputting voltage, even though is variable (from 5 to 9 volts in the case of Turbo Charging) would only relate to varying the mAH per / Sec if you will, from a quicker or slower "Consumption" (i.o.w. if it is quick charging, the rate of supplied mAH is faster than slow charging, so the total amount or capacity of charge is the same, it is just a matter of how quickly can you refill the empty bucket of water, with water).
I am using the Pure Nexus Project Nexus 6 Rom, flashed with the latest Radio, and I am extremely happy and very stable build (so much so, I even sent beans some props and thank$you donation). What I am disappointed with (even with previous roms and build from 5 all the way to 6) is the battery capacity (I loved the Turbo Charging so much, I did away with carrying a battery bank and purchased a 2nd Turbo Charger for the office). I did not purchase the phone new, but did get it in an almost new state (purchased from the typical, "I got to dump this just came out phone and get the latest released phone" type of tech junkie). FWIW, it is the 64gb model, and about 6 months old (I have the google bill showing the manufacturing date and sell date). I can't say I am impressed with the overall battery capacity of this phone, but it is designed to get me through a day 90% of the time, so I am never really worry free, it simply not a tank like some other monster phones that I have had (I like smartphones with a minimum of 6" of screen, my previous phone was the Samsung Galaxy Mega 6.3).
I will be honest, I have always been a battery junkie from my days as a Radiocomm R&D department tech, so I have a carryover Battery Analyzer (5K $ piece of bench equipment) that I can use for most of my battery related equipment (from battery powered yard tools, commercial grade walky talkies to household products like cordless home phones). But things like cellphones would not work, because I do not have the correct adaptor that has the correct resistance type, delta voltages, and connect-ability. In most cases if I jerry rig something (like I was curious to know what the capacity of an Energizer D size battery was compared to a Duracel D size Alkaline Battery capacity was, I could read the output mAH capacity from either battery and know which does really last longer) I can get the output capacity but cannot perform a 3x count battery analysis (which basically performs a full charge discharge 3 times in a row and spits out the 3 capacities back) which in fact I would NOT do on a Lithium battery for obvious reasons.
I found myself seeking threads in these forums about different ROM's and SOT obtained. The results were way different between different users, some claim to get 2.5h SOT some 5h SOT under normal circumstances.
Under normal circumstances I never get more than 3h and I suspected that my worn battery (598 charge cycles according to "Charge Cycle Battery Stats" app) was far from the original 3000mAh.(Thats a manufacturer stat obtained in perfect conditions, real world must be around 2800mAh)
I needed to measure the capacity left in mAh,so I bought a USB ammeter power meter (Keweisi white digits, but you don't need it, I'll explain later).
Using the Power meter, to measure properly you need to avoid thermal loss and power loss when charging:
- Note 5 completely discharged at 1 or 2% battery left.
- Disconnect the Fast charge option in Android.
- From start to finish keep the note 5 Switched off.
- Use an USB low power charger, mine was charging at 0.8A
Results: 1800mah that's far from the 2800mAh(3000mAh) when new.
(Same test I'm getting 2200mAh out of the original 2800mAh on my old Galasy S5 Neo.)
You don't need USB ammeter, Android has a builtin ammeter calculator(estimation).
Today I depleted the battery (2% left) of my note 5 again (Rom based on Android 7.0) and under battery usage I added all the "Computed Power Usage" in mAh giving the next results:
mAh
557 Cell standby (I worked underground today)
333 Screen 2h53m (30% brightness and auto brightness on)
271 Device Idle
221 chrome
203 Android OS
43 Google Play Serv.
39 Androyd System
27 Youtube
20 Yahoo Mail
20 Wi fi
17 com.android.systemui
Total: 1751mAh
This result shows that the phone itself makes a good estimation of mAh juice available in you battery.
As an anecdote I run the same test that Jerryrigeverything in YT with his Note 5(6 month of use): Playing a 2k video in 100% brightness( auto brightness off) with sound and in Flight Mode(not even wifi). He gets 6h20m, I surprisingly get 6h. But those test are only worth to compare Note 5's
Conclusions(my own and humble): Surprising degradation of my battery, specially compared with the results obtained in my S5 Neo. According to "battery university" (a good scientific source of information about Lithium-Ion) I might have shorten the life of my battery abusing of the fast charge mode.

Same here, the problem is that is quiet impossible to find a genuine battery for replacement. All those on amazon and ebay are crap.

That's the next step, find a good provider and compare capacities.
What I know so far is that there's 2 different battery models:
EB-BN920ABE The most common, but most reviews complain about being 4 or 5 mm shorter, ...less volume less capacity.
EB-BN920ABA Difficult to find, It seems the original replacement according to this picture:
https://ae01.alicdn.com/kf/UTB8YQ_yanzIXKJkSafVq6yWgXXa0.jpg The original is the right side one.
I found a Canadian provider who seems serious (free of fantasy marketing) who also ships worldwide, it looks like the original, (or a extremely good copy) I'm going to take the risk and try it:
https://www.ebay.co.uk/itm/OEM-EB-BN920ABA-3000mAh-Replacement-Battery-for-Samsung-Galaxy-Note-5-N920-N920A/401346669803?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

How did it go? Those eBay batteries tend to be pretty bad in my experience.
Finally someone else is concerned about note 5 battery capacity, i replaced mine with an original one in feb 2018 from a nearby samsung service center for $40, i used Accubattery app to measure and compare the battery capacity of the old vs the new battery.
After two years of usage and fast charging enabled in all of charge sessions, the old battery was giving me 76% (2291 mAh) of the original capacity, while the new one is giving me 89% (2675 mAh) right now, the weird thing is that it was giving me 90% right when i purchased it, i dont know if this is normal or not.
As for SOT, the old battery was giving me 2.5 hours on average, with an average of 17 hours of total usage, the new one gives me 3.5 to 4 hours with an average of 20 hours of total usage (disconnect at 100% from charger and drained to 1% or 2%)
Hope you find this post helpful

I'm in the same boat as you. My battery life blows and I am looking for a decent replacement so I don't have to buy a new phone. How did that one work out for you?
The Note 8 promised long battery service life, that is, high maintenance of original charge. Samsung promised that after a year, the battery would still retain 95% of its original capacity. Using Accubattery, my Note 8 has achieved this. This is vastly superior to what I experienced with the battery on my Galaxy S7.
I don't know much about batteries, but from owning Thinkpad laptops, I know you can get long service life from a lithium battery by deliberately not allowing it to charge to 100% of rated capacity (this is a setting in the Thinkpad battery firmware, accessible from Windows or Linux). If this is the same way that Samsung did this, it means the Note 8 battery has more capacity than it reports. (3300 mAh), achieving long service life by undercharging. This would mean that Samsung gets weaker reviews since out of the box it offers less runtime, but owners get the benefit of sustained runtime compared with previous phones. A pretty courageous move, if my speculation is true. The other possibility is that the Note 8/ Galaxy 8 has some very high spec battery technology which is significantly less exposed to typical capacity degradation.
So now, the Note 9 has a 4000 mAh battery but with almost no change in dimensions, which is curious. Is Samsung still claiming the long service life that it claimed in the Note 8/ Galaxy 8 generation?
I would like to know the answer to this as well.
The device is thicker and wider and 700mah isnt THAT much more physical size wise. But why wouldn't their claims on battery longevity still hold up?

I actually didn't find the same situation to be the case on my S8. I found that at new, the battery could pull close to 6h SOT, and after 500 cycles or so (checked with Phone INFO app), it was closer to 3.5-4h. Not that 4h is a bad figure, and it was still fairly respectable, but it is not 95% retained. Same for my mom's S8, at first was doing 6.5-7h, and now is pulling closer to 3h. I got my battery replaced under warranty at the 1 year mark, but my mom hasn't and it's starting to show.

It might be a bad software update. My Note 8 battery started to suffer until I upgraded to Oreo. Maybe some thing to do with refreshing the battery meter.

Have we seen any official documentation of retaining that 95% battery in Samsung product webpages or leaflets/warranty information??
It was all about official "Claims" for the S8/S8+/Note 8.
Samsung haven't made the same "claim" for the Note 9 yet. Probably will, without mentioning in any official documentation/product pages.

Yeah, it wpoould be best if they included 5.000mAh but 4.000 mAh is still acceptable.
I'd like to know how other's batteries are holding up. I've had my 9 for a month or two now and AccuBattery Pro is showing my battery health as 97% (3882mah) already. I'm not sure how reliable that app is for that stat, but dropping 3% already kind of has me irked a bit.
The only thing i have noticed is when my s7edge and s8+ got oreo my battery life on both those devices was no where near when i first got them. As for my note 9 the max SOT i have gotten so far is 8 hours and 12 min in QHD, i was sitting at 11% battery before i plugged it in.
I have the Mate 20 Pro and it absolutely smashes everything out there. It has outstanding battery life

There was a semi big debate about this on this forum. Accubattery Pro doesn't apparantly show the correct figure from the get go. I'm assuming you didn't use Accubattery from day one to show the before health stats to current? I say this because from day one mine showed 97% health or lower.
Aida64 app also shows the battery capacity at below 4000mAh from new. Hence why Accubattery doesn't show 100% health .
Either Samsung has not implemented 4000mAh batteries in many devices or they are designed in such a way as not to show their actual values in apps.

My Note 9 is 5 days old, and Accubattery says 94%. It's nonsense.
So basically AccuBattery on the 9 is only really good for the charge alarm it sounds like. That makes me feel a bit better. Either way I get great performance so I'm pretty happy with the phone. I normally get between 8 and 10 hours sot so it blows all my older phones except my Note 4 with 12000mah battery out of the water.

Those apps are just estimating. There is no hardware components for such accurate power usage observation in the phones to tell you exactly how much the battery degraded/hold in the first place. Don't trust them that much + battery life in long run is not affected only from the battery degradation, but also from updates and not least important - the applications themself that becomes heavier with every update = the CPU/GPU scales higher and that needs more power and thus shorten the battery life.
Simple example, my HTC M8 eat for breakfast every app back then when it was released. Messenger? NP! Facebook? Lol, 10% CPU usage. And so on. Nowdays it will still run all of those fluid and fine, but instead of 1500MHz 2 cores for example, will use 4 cores at 2000GHz. This affects power usage when it's all apps basically. So it's not just the battery degradation.
That should sum it up about the topic.
My note 9 is also around 94% battery since day one. But this was not the case with the Note 8. I was at around 103-105% battery capacity on the Note 8 for a long time.
It is an estimate and not perfectly accurate but Samsung does have the ability to measure battery wear.
On jailbroken iPhones you can get the exact wear percentage and now iOS has battery wear shown directly in battery settings.

Your first paragraph, same here. Hence why I mentioned either Samsung have changed something battery electronics wise or they are not giving us usable 4000mAh.

If any of you are still using the note 5 with samsung original battery (never replaced the battery)
Kindly help to measure the mAh
I bought a few after market batteries, i can never reach near 3000 mah on this phone with USB multitester
The reading on the USB multi tester showing max around 2300 mah.... (from 0% - 100%)
I do not know if making this thread will help..
Have not been back here for many years..

how to measure
Thanks for replying. I purchased from Amazon a very inexpensive tool called "usb multi tester" it can test like the amp being charged to the battery of the phone etc... it is straight forward setup. Costs like $9. It shows the voltage of the usb cable. Amp and capacity when the battery is fully charged.
Replacement batteries are poorly made and I consider them as a fire or explosion risk. If a battery fails I get another device. Phones are not built to be repaired.

Thanks for replying. I've bought many fake batteries for my note 5 (though they look exactly the same to the original one) to test and also have bought a few from trusted sources.
But none of these batteries could be charged up to 3000 mAh via usb multi tester to measure the amp being charged to the battery.
How we convert irreplaceable/unremovable battery type smartphone to be the replaceable one having its connector replaced to be the standard that is used for replaceable battery type ones?
It's ASUS Zenfone 3 (or 2 not so sure)
How are the main signals, else than + - i.e. battery state indicator (BSI) clearly explained or better with schematic ?
Welcome to XDA
Just replace it, and be happy.
It's no worse than my Note 10+...
The Zenphone 2 is harder.
