Note 5 Battery capacity left test ( mAh ) and hours of SOT

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
I'll post results in about 6 weeks....

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?

best charging practices? Samsung Service center

A friend of mine went to a Samsung Service Center with his s9Plus for couple of questions. One of those questions was what the best method is for charging phone. They said minimum 5% then charge all the way up to 100 in one go. I was surprised with this answer since I did a lot of online research on this matter for my Note 9. I concluded and that the pro's are talking about keeping it between 20% and 80%.. and I'm doing that ever since..
Do we have an expert here on this matter?

Not an expert, but plenty of apple and android devices that I have kept for several years and never wore out a battery. My iPad mini is around 5 years old now, no issues. Galaxy s7 edge traded at 2 years old with no battery capacity issues. Old Samsung Galaxy Note 8 (the tablet from like 2012) still going strong, etc. I charge my phone when I feel like it (usually overnight) and take it off charger when I need to. I don't care if it's charged fully, I don't care how long is been charging. My life does not revolve around my phone battery percentage. This 20% - 80% thing is stupid. Your battery will far outlive the useful life of your phone.

Not an expert either but I do have the capacity to research this stuff myself. The age of the battery actually has little impact on it's capacity, so just because a device is X years old, doesn't mean it's battery capacity is going to have dropped significantly. It's the charge cycling of the cell that causes the degradation, temperature, depth of discharge, charging speed and the number of cycles a battery has had are more important. While I'd take the Service Centre rep's advise with a grain of salt, Samsung have clearly put a great deal of work into refining their battery technology, so do you need to worry? Probably not.
Although, if you think the battery will far outlive the useful life of your phone, look at Apple and all the batteries they're having to replace.

That all I know, and trust me, my devices go through plenty of charge/discharge cycles in the 2 to 8 years that I own them.

[OneUI 2.1] How big is the battery life improvement for you?

Although to a certain extent, we even came to doubt that Samsung would update the Galaxy S9 and Note 9 devices with the OneUI 2.1, it is finally here, and it cames with Deep Sleep Apps feature, which will allow to actually suspend all services and processes associated with an app.
This has resulted in a relatively big battery life improvement when the device is on standby with S10 and S20 devices in controlled tests1.
Galaxy S9, S9+ and Note 9 are devices released more than 2 years ago, and surely the battery stamina is not the same as they were in their first months of use. Samsung stats that the batteries used on these devices should keep a decent stamina for 2 years with the average user.
Some people have used their phones with battery care measures1, in order to extend battery life.
So, with the recent release of OneUI 2.1 for Samsung Galaxy Note 9, the battery life with the device in standby is expected to be longer (but not the screen on time), although the magnitude is yet to be determined in the coming days.
This thread is aimed to share our opinions on the subject, as the update becomes available and we can evaluate the battery life.

IOS uses a choise in his battery settings to charge the battery up to 80 % of it's capacity and then charging will stop to improve the battery's durability.
It's known that standing in battery's 20/80% capacity increases its life and durability and doing this you can charge how many times you want because one parzial charge will not be counted as an whole cycle of charge so the battery might last more than 3 years going on like this.
This choice is not implemented in Android even with one UI 2.1 and it's a shame even if the new feature will improve battery's autonomy due to the lower consumption of the apps and even if it's impossible to perfectly be able to stay in it's 20/80 percentage range, there's an app that I found that will avert you when reaching 80 % of its charging capacity so you can disconnect the cable to preserve the battery....

You're right and I keep charging between 30 and 80 but this shouldn't be how the phone charges by default as you said. Many people charge from 15 to 100 and want that extra 40-50% they'll get by doing so. I found that without fast charging it takes 1 hour from 30% to 80% so it's no big deal to look at the clock when you leave the phone on the charger.

Even your right, there are even people that continually from 0%(completely dead) goes to 100% after charging the battery for the whole night... that's why what I said for charging should be a choise (like in IOS) and not a default setting.... strange thing that Android or Samsung didn't consider implementing this choise. Fast charging even worns the battery first... it stresses the battery and it will last less but at least they gave us a choise in using it or not.

Absolutely true! Samsung should have implemented a feature to limit charge at 80%, or implement a Bixby Routine to enable this behavior (for example, when charger is plugged at night)

50% increase in my case. And i used OTA Package to update manually.
From: 4h SoT in 24h
To: 8h SoT in 24/30h
Idle times are impressive.
EDIT: just FYI, i rarely charge up to 100%. So my average case is from 85/90% to 5%. Very rarely do i go for a 100 to 0.
One UI 2.1 improvements are all courtesy of the Deep Sleep feature.
I've added everything i barely use or dont need to create wake-ups on the Deep Sleep list. On the normal sleep list, i have low priority things like Play store, etc. And i make sure i white list everything i need untouched (Messenger, WhatsApp, etc) and also do the same thing on the Memory management. Solid results.
Edit: 100% to 1%. 10h SoT with a 30h cycle. It's like getting better and better.

My tab a 2019 has the 80 percent feature and I do not understand why they wont offer the simple setting actually I do because phones they want you to replace the phone instead of the battery in 2 years. I run my note 9 from however low to 100 every night but only because I dont have the option these newer android 9 then 10 now 2.1 adding more and more apps into the firmware but wont add a simple little feature as this. Also I would like to be able to choose if I want to do ota with my data! But I cant.

For me One UI 2.0 was already worst with about 3 to 3.5 hrs of screen on time. Now with 2.1 i barely get close to 2 hrs of SoT. My note 9 is running stock since i bought it at launch and have never done any factory reset. Only thing i do is wipe the cache after a upgrade.

Bro you need to factory reset and start fresh and if that doesn't help something is wrong with your battery I get 9 SOT all the time with 10 2.0 with android 9 it was about 6 SOT, I haven't received 2.1 yet. I have us unlocked version.

You have a snapdragon variant which is anyway much better than exynos variant (my phone) for battery backup.
Sent from my SM-N960F using Tapatalk

Stop saying Exynos is not good for battery life. I can easily get 8h SOT of regular usage on my SM-N960F running OneUI 2.1. Obviously I don't play games like Asphalt 9, etc but I never use power saving modes and never limit myself in order to save battery life. I play 8 Ball Pool when I want to, I watch YouTube for as long as I want to, I browse Instagram and use Samsung Internet Beta when I feel like it. Not once have I ended up in a dire need to recharge when I was outside or when I needed to use the phone. Also the phone charges 50% for 1h (I charge between 30 and 80%) so I just leave it charge while having dinner, watching TV or something like that - when I normally wouldn't use the phone anyway.

On my N9 seems battery life abit improve from previous 2.0. Sammy did great job this time.

Here is my screenshot to prove it.

It takes time to see improvement in your device's battery life after installing OneUI2.1. As the software AI needs to learn all your habits again before any improvement in battery life will occur. This process should take a few weeks

Question Battery life not lasting a day....

So I bought the new S21 Ultra on the pre order the day it was announced. I was one of the lucky ones to get early so I could leave a review.
Coming from a Note 10+ that I had for a year and a half, I was really excited for the S21 Ultra, but was really disappointed with the battery life. I've had the phone for 5 days now and since the very beginning I've not been able to use the phone for the whole day on a single charge. It's been giving me screen on times comparable to my Note 10+ (4/5 hours) which is a much older device, but I thought maybe this was the way all S21 ultra's were behaving, just not very good battery life.
BUT, yesterday all the youtubers started to publish they're videos comparing batteries with older S devices and Iphones and their S21s were doing amazing, giving them screen on times of up to 13 hours!
I contacted support but they said this would be normal as my phone was still learning user patterns... but I'm not sure if that would affect it as bad as it is at the moment.
Also, I installed accubattery which is not 100% reliable but compared it to my note 10+ and it seems that battery health is even lower that my Note (95%)! Which I've had for a year and a half!!!
What do you guys think? Should I send the phone back? I'm really concerned that I just spent all this money on a new phone for it to be so bad with battery.

Try disabling all power management.
In Developer options>standby apps all buckets should show as active otherwise power management is running.
Google Play Services, Backup Transport and Framework are known hogs.
Disable all the bloatware, turn off auto sync for gmail, turn off all feedback.
You'll need to sort it out and optimize it. Took me months to get my 10+ sorted out. Fortunately it's running on Pie so I had more diagnostic options.
Returning is a thought as 5G may have been poorly implemented and another source of power drain. I think everything after the 10+ 4G both hardware and OS are train wrecks... I see very little incentive to "upgrade".

Maybe post screenshots that aren't below 5 kilobytes. Lol. I'm guessing you have an Exynos variant?

It's too early to judge the battery life, also accu battery app is not good at all, it's not accurate as your own phone's batterymeter.
Also, you need a week or so to make sure the phone get optimised according to your usage.
Does your phone have Exynos 2100 or Snapdragon 888?

Mine has the Exynos 2100. I was just going off from videos like Mrwhosetheboss. He got 8 hours of screen on time. And he probably tested it when he got the phone no? And I'm litteraly getting half of that... and not even pushing my phone to the limit like he did on his video. I mainly use social media apps and YouTube.

I suggest doing a factory reset before you think about sending the phone back. Also, initially, be careful about what aps you install - try going with a minimal number of aps so you can get an idea of how the battery does when there are no aps that might pull from the battery - after a few days, add all of the aps you have been using (while avoiding any that might be a battery drain) and try for a few more days to see if you are seeing improved battery life. Good luck - hope it all works out for you.

Reloads -never- find the root cause and many times even if the problem is "fixed" it eventually returns.
Exceptions; old loads, software induced bootloops, viruses, and major firmware updates.
Expect issues with the 5G devices from poor hardware implementation. No fix for this.

I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

How much with screen off is it sucking down?
If more than 1% @ hr with AOD on it's probably Google and cloud crap running in the background.
You can optimize it to improve performance.
It's easier to do this with Pie though; Q and 11 take away critical tools and use scoped storage which wastes cpu cycles.

Regardless of the model or OS version most carrier phones will need to be optimized for good battery life and optimum performance.
My 10+ was a hot running bandwidth hungry hog until I toned it down. Today it's hard to believe it's that same machine.

You are right, I agree with all you said. It is kinda sad though, as for instance, my ex Asus Zenfone 7 Pro had an absolutely mindblowing battery life, without any tweaks. I just used it. With all the hype around the S21 Ultra, I believed it again. The only Samsung I used with good battery life was S20 FE 5G.
Will give it a go with what you say though, thanks.

Well, i believe what you are saying about battery life, but what i have seen so far is promising, i mean when S21 Ultra with Exynos 2100 beats iphone 11 Pro Max and 12 Pro Max, i guess that's a good sign!! But for sure, we use our phones in different way than each others because maybe you use it with 4G/5G enabled almost all the time while these tests are just using Wifi and maybe without any SIM card which means the battery consumption will be minimum at this part.
I have S20 Ultra with Snapdragon 865, i get like an average of 6 hours SoT and if S21 Ultra Exynos gives me the same SoT, i'll be happy!!

SOT is not everything...we travel, we move, you cant accept a phone that gives you 12 hours of standby in total. This is bs and useless, you cant rely on such a phone.

My AT&T 10+ was not real bad (or good) the first few days. After enabling power management it went to hell.
Eventually I disabled all power management and one by one tracked down the hogs.
Because of dependencies simply disabling and/or turning off say Google Transport and Google Framework isn't enough, firewall blocking Google Play Services* then clearing data on all 3 periodically finally stopped this hog dead in its tracks. These will run in the background when the screen is off stealing power for nothing. Sometimes the Google apks are misreported as other Google apks presumably because of the interlinking dependencies.
Try using Galaxy Labs Battery Tracker.
Developer options>running apks/cache can also yield clues. With an unrooted phone there's some serious game playing to track this garbage down.
Anything app that's cloud or carrier is bad... lol.
Disable all feedback and syncing except for texting; manually sync gmail.
*needs to be unblocked occasionally for gmail to download and for Playstore (another apk you should disable/firewall block when not using).

Try disabling 5G if you are not using it, for some ppl SmartThings drain a lot of battery but you should see that app in log. Can't wait to get mine, also E2100 and coming from Note 8. Was rly looking to have a 2 day phone.

That's a thought that's worth a try.
From what I've read even disabling 5G doesn't completely stop it's parasitic battery drain.
Maybe the latest generation chipsets are better but early 5G was poorly implemented giving a marginal speed increase on most phones of 20% when available.

Is this on the snapdragon or exynos variant?

I am on the first charge, but the battery life is so far pathetic. Omg! And everyone on youtube praise it... Down to 85% in 2 and a half hours and 50 minutes of SOT. Shame...

So, 15% drain in 2.5 hours with nearly an hour of SOT. 15% is about 1/7 as a fraction. Now, 7 * 50 / 60 = 5.83 hours of SOT and 2.5 * 7 = 17.5 hours total. My Note 10+ (S20 Ultra on order!) doesn't do any better and NEVER did. If I use my phone for 6 hours a day (of SOT) it's pretty much done for.
I think people are being way too picky these days - just complaining to complain. If you really want I'm sure you can tune your phone so it gets 3 days on the battery. It'll suck and not do much of anything but, sure, you can do it. I've got a smartwatch and the same thing applies. I can tune it so it works for two weeks on the battery or I can actually use the thing and get 2-3 days. I choose 2-3 days and have stuff I want to use. I'd rather my phone be reactive and tell me when I've got emails, etc than to get super long battery life and basically have an inert brick in my pocket. I have a cellphone so I can use it for stuff. If that makes the battery not last long, oh well. If it can get 5-7 hours of screen time while also lasting through the day, great.

My 10+ draws roughly 1%@hr* with AOD on.
SOT draw varies between 9-12%@hr
Roughly 10%@hr watching vids on Samsung internet with surfing on Brave being the highest usage.
I consider it fairly optimized at this point.
*4300 mAh battery with little degradation.
No 5G running on Pie so not scoped storage either.
Figures are from a charge range of between roughly 40-65% as I rarely charged beyond 70% or discharge deeper than 30%.
Actual usage be more if I had started at 100% because of the power density difference through the power range ie 1% at 20 is far less watts than 1% at 100%.
A/V=watts. Less voltage means less overall mAh per % plus the additional losses due to voltage stepup power conversionas you dip towards 30% The closer to 100%, the higher the voltage with more available mAhs per battery% as well as less stepup voltage power converter losses.
A phone's wattage and V+'are constant so as the battery voltage decreases it draws more current ie mAhs.

You are also right, but , when you used something that does both keeping you up to date, and having a brilliant battery life, then it becomes disappointing when you change it for one that doesnt.

Question Low estimated battery capacity

I have been using my brand new Tab S8 5G for 8 days or so. I have AccuBattery installed. The estimated battery capacity has been very low from Day 1. Currently I get:
Battery Health 87%
Estimated Capacity 6759mAh
Design Capacity 7760mAh
Based on 31 sessions 1031% charged for 69688mAh
I understand it takes a few days for AccuBattery to function accurately, but I think it's been enough. The design capacity has been automatically measured and already adjusted to a lower value than what Samsung advertise (8000mAh). I've also installed 3C Battery Monitor app, but the estimate is very similar (3718). I have bought 2 other (non-Samsung) android devices in the past few months, but their estimated capacities are much closer than 100%.
Has anyone expericed the same? Or do you think mine is a bad lemon and should be returned? Any insight would be much appreciated! Cheers.

Are you charging to 100% or just 85% (battery save option). If you charge up only to 85% then it is accurate.

Thanks! That's a very good question. I have used the 85% charging limit option for a couple of days but left it off for the majority of time.
But wouldn't it be the same from AccuBattery's point of view if you used the option or not, as the tab tells the app 85% as 85% not as 100%? (or maybe my assumption is wrong).
I have since updated AccuBattery (which cleared all my history!) and started self- recalibrating the app as their website suggests (you go down as low as you can, and start charging until drawing ampere really finishes at over 100%). After a few iterations, hopefully the app will show more accurate info. (Or not, I will just come terms with it!)

İ think accubattery calculates with the Design capacity of the device, with the the Option to charge up to only 85% you would have charged up to 6800mah vs. 8000mah 100%. But i could be wrong too

Just not to open another thread. I have a similar situation with my tab s8+. All apps that do something hardware/battery related report the battery to be 9800mah and not the Samsung claimed
10090.
As for now I'm letting sccubattery do its reading, but so far battery life has been ok for a tablet with high end Specifications. On average I get 8 to 9h of SoT on average not very demanding usage.

Yes my S8 has also a considerable difference between Samsung's advertised battery capacity (8000 mah) vs the capacity apps like AccuBattery read (7760 mah). That's probably their way to prevent users from overcharging their devices.
On top of it, I have also found that my tab can go quite a bit after showing 100% charged. Following AccuBattery's re-calibrating (re-benchmarking) method l mentioned earlier, in one charging episode I saw my tab going up to 8700 mah or so until it started showing 0 or negative charging values about 40 mins after it showed 100%. Having overcharged my tab a few times this way, AccuBattery now shows about 100% for battery health. Obviously this isn't a good way to charge your battery in terms of its longevity, but it might help to calibrate your new device with a battery app. When the % reaches 100%, the estimated capacity on AccuBattery is normally much lower, something like 6700 mah, as I initially got. I need to do more tests, but I find the leeway Samsung spare is a bit too much.
Interestingly, I have also found quite a bit of variability in this 'fake 100% battery' setting across different manufacturers (or at least different devices). I am applying the same recalibration process on my Xiaomi Pad 5 Pro and OnePlus 8T. They are both about 9 months old. My OnePlus behaves somewhat similarly with my Tab S8, showing about 10% extra capacity after 100%, whereas my Xiaomi really stops charging when it reaches 100%.

Hey. This is my stats on my S8+. I recommend trying to completely discharge the battery to 0%, charge to 100% and wait until current is 0 mA. Do this min 3 times in row. Then you will get a more accurate reading
