battery capacity - Nexus 6 Q&A, Help & Troubleshooting

How can i find out how much capacity my battery has left. I had AccuBattery installed and it showed the battery was still at 96% capacity. I find that hard to believe, got the N6 for the past 21 months.
Is there another app or way to get a accurate status of the remaining battery capacity?

no one got any idea on how to find out the remaining capacity of my battery? Because i dont believe its still 96% after 21 months

To test the battery capacity the battery would have to be removed from the device and attached to test equipment none of us have. It would then have to be put under load and tests run with that test equipment to get the answer.
How old is the battery?

Thanks for your answer. Thought it would be possible without testing equipment. But phone still works fine, and battery last me long enough to get through 1,5 - 2 days with normal use.

Longest batterylife (8 times longer) information! *Easy, takes 30 seconds to learn*

If the battery is only charged to about 75% it will last about 8 times more discharge cycles then if it was charged to 100% every time. Which is pretty damn much!
100% charge gives 350-400 Discharge cycles.
75% charge gives 2400-4000 Discharge cycles.

I don't know of any app or kernel that does this automatically, if you know or can program one please update this thread.
Meanwhile we have to just unplug charger by ourselves at around 70-75%
Please press thanks and write a reply what you think if this information was usefull to you!:good:
Well, if it's true, it's a huge improvement for only 25%, we can perfectly last a full day with 75% of battery
This is really good battery info. Thanks.
My personal view on the matter is for 15 bucks, I'd rather pick up a replacement battery a year or two from now when I may need it and just replace the cell rather than work to keep my phone charged closer to 75 percent every day in order to see some of the par-charge benefit the article discusses. I'm not suggesting that should be your position.
Based on how I use my phone, starting nearly every day closer to 75 percent than a full charge, I'm guaranteed to run to shutdown many more days than I would if I accumulated the expected number of full cycles. There's enough indicators to tip you off when you reach end-of-life on your cell: you usually see very significant shortened battery life and/or big cliffs in useage like draining evenly say between 100 and 78 percent and then going from 78 to 60, and then even depletion again usually indicates cells failing. Point is batteries don't go from good to bad overnight.
My perspective after just very recently moving into an S5 from a RAZR Maxx that required a good bit of phone disassembly to get to that battery, picking up a $15.00 replacement and keeping my battery topped off is the way to go. :good:
I have never had to replace a phone battery, they have always lasted until I upgrade. Great read but it seems the author was mainly referring to laptop batteries.

Be careful with info from batteryuniversity.com. It is largely geared towards engineers using raw cells, not users of consumer devices. This leads to people making incorrect assumptions. For example you may read there about the dangers of discharging Li-ion cells too far. But your device probably (if the engineers have any brains) already builds in some buffer, and shuts off/refuses to power on if it's a safe level above that. It's hard for us to know what levels Samsung considers empty and full in comparison to the actual cells.
I'm not saying this is bad advice, just that it may not really make that much of a difference in reality, and it's tough to do in practice.
my girlfriends S3 is 2 years old now and battery lasts still the same long as it was new.
i think phones anyway doesn't charge the battery to 100% full capacity or even let it discharge to 0%
Anyone tested this to see if it works better for battery performance?
Maybe if I had something like a HTC One I might do that because you have to be like a freaking safe cracker just to get at the battery, but on S5 I'll just keep going to 100% and buy a new battery after 9 months because I am a heavy user and lose a lot of capacity within a year.

thanks for the great info mate .
your input was needed.
It's just click bait, chances of keeping the phone for 4000 cycles is 0 for me.

your actual battery capacity in 3t

Can you guys download accubattery and check your estimated capacity against design capacity and thus you battery health.
Please attach details of your ROM and the age of your phone.

3277 mah, beta 9 (stock), bought around Xmas time. Not sure if the mah will change if app is installed for a while and it sees several cycles.
It showed 3250 on new phone

Actually it just compares the percent charged to the change in mAh so it isn't some weird bs like "deleting batterstats.bin will increase battery life". This reading is also shown in settings in MacBooks.
Mine was at 94% estimated capacity the first day i got the phone at its release. Now, it shows 92%.

Is there a way to verify battery capacity to verify battery replacement?

With the announcement of the 1-year extended warranty, I went to go replace my battery today at ubreakifix. When I picked it up, the employee gave me the feeling they didn't actually work on my phone but billed Google for the work. Besides the fact that the things he said made me feel like they didn't actually work on it, I noticed when I picked it up the battery was within a few % of when I dropped it off. I'm trying to see if there's a way to check capacity or anything of that sort I can do to verify that my battery was or was not actually replaced.
I appreciate any help.
Your SOT should noticably longer.
New batteries typically have around a 50% charge on them.

It was around 47% when I picked it up but I dropped it off at 53% which I thought was odd. That's good to know the range is correct for a new battery though. The guy was sketchy and made several comments that made me think he didn't actually touch it. I was hoping to check capacity or something to verify the change but I'll use it tomorrow and see how the battery life compares. If I'm still having battery issues, I just wanted to have concrete proof if I went back. He made a point to say "if it's still acting up then you'll just have to call Google and have the device replaced instead".

I've seen a lot of bad techs. You could always take it to a 3rd party repair if it turns out the battery is still defective.
Maybe he's just shifty acting in appearance only.

Yeah hopefully he was just awkward or something lol. I'll see how it plays out the next few days. Hopefully he replaced it. I plan on buying the Pixel 6 Pro but it would be nice for this to hold off until that comes out.

You can use AccuBattery to check estimated battery capacity. You'll have to go through a few charge cycles to get an accurate estimation.

I might give that a try as well. I heard that just estimates but I guess that's better than not having any idea at all. I'm doing the first full charge since I got it so I'll download AccuBattery and run it the next couple days. Thanks for the suggestion.

It's total battery capacity estimates are not accurate. If you had been using it before it's SOT/% history would be useful.
I use it track my battery usage % vs SOT to spot misbehavior.
It's charging time/% history is also useful for monitoring charging. Erratic fast charging is one of the signs of a battery failure.

It's history is but the actual mAh measurement isn't.
With no calibrated reference of the voltage to mAh ratio it can only do so much. I believe it's measuring voltage drop and calculating current and mAh from that instead of voltage×current.
Whatever the reason(s) it's absolute battery capacity isn't accurate.
I maybe mistaken but even though some power controller chips have current sensing capabilities, Android doesn't use that readout or make it available to any apks.
An Android shortcoming.
A Developer here maybe could or has shed light on this before.
Edit: some brands/models can apparently:

No information on Samsung models that I could easily find.

Like I said, I have found it accurate enough in my experience. New phone is around 100% estimated capacity. Year later, 90% or so. Year later 85% or so. Done this with several phones.
Not here to debate or argue about it. If the OP doesn't want to use it, they don't have to.

That 10% is from the original OEM battery and the replacement. Android it's self lists it at 4100 when it should be 4300 new. Accubattery uses the Android figure unless you change that value.
He'll get a good enough idea if the phone last longer during usage. It should be a noticable improvement... and I hope it is.

Just reporting back that it was definitely changed. I charged it before bed and decided not to put it in the charger over night to see what happened. I woke up and it was still at 99%.
It's been off the charger since 11pm yesterday, it's 8pm now and I still have 16%.

Another way to check is with this online tool https://bathist.ef.lc/ Battery Historian. Make sure to charge your phone to full keep on the charger for a bit longer even after 100% If you can do it with the phone powered off that's even better. Turn the device back on take a bug report and upload it to the site. Then look for the "Coulomb charge" value and mouse over it. It will show you how much the device charged in Mah say for example you see 3650 then you divide it by the battery capacity for our device which is 3700. This means your battery health/capacity would be about 98.6%.

Assuming that phone has accurate current sensing hardware and it's readout is available. All Androids report voltage relatively accurately... current not as much so.

Question Battery Capacity Question

Hello all,
I got my self a Find X3 Pro a few months ago and I noticed that Accu Battery Pro and Aida 64 Battery, never reach the min capacity of 4400mah or typical capacity of 4500mah
Is this thing a issue ? Or my battery is degraded from brand new ? Or is this a software incorrect reporting issue ?
Thanks in advance !
Make sure to let it charge for about 7 minutes after it reaches 100%. The phone is not actually fully charged when it reads 100.
See here, after the first charging graph
Oppo Find X3 Pro review
The Oppo Find X3 Pro employs a similar display to the one we enjoyed on the Find X2 Pro. It's a 6.7" LPTO AMOLED screen of 3,216 x 1,440 px resolution or...
www.gsmarena.com
Then check again the meters. If they still read 4200, then you may have a degraded battery.
Also, consider that even if the phone is "new", it may have been produced a long time ago (like a year ago or more), thus suffering from some battery degradation already.
I always make sure I let it charge for about 10 more minutes at 100%. Still between 4000mah - 4200mah it displays.
Recently I replaced the battery for an old Mi 5s Plus and after a few charges (3-4) it will show the correct mah of 3800 (~3792mah)
So, did someone actually have these apps display the correct rating of the battery ?
I will give it a try tomorrow, but my phone is 1.5 years old at this point, so I don't expect to see anywhere near 4500 for sure.
I checked mine, but only 2 cycles it showed 89% The phone is 8 months old.
Thank you for your feedback...
My phone is barely 2-3 months old, should I try for warranty ?

Try to charge slowly to 100% using a 3A cable or less and leave it in charge until Aida64 show complete charged, then check charge counter how much mah show. Normally the counter will be a little less respect to declared capacity, like for hard disk the real capacity is not the full declared capacity. My X3 pro is used and charging to 100% show less of 4000 mah but battery life isn't bad.
18 months old phone, about 84% health (only one measurement though)

I'm sorry to tell you but you are mistaken, my ex Red Magic 3 phone indicated my rated capacity for battery and my recently replaced battery for Mi 5s Plus also indicated 3792 mah out of 3800mah, so I presume the issue comes for a incorrectly stored phone when I purchased it or old batch.
I always charge slow or at 1.8A because I'm never in a hurry, I even charged it at 500mah overnight and it went to just 4115 mah out of min 4400mah

No it depend from device to device and also from update cause it change also with kernel version. When I have OnePlus 7 pro always charged slowly bu never reached the full capacity of charger counter, this changed when I tried Oxygen OS 12 India beta, the battery show 4500 in charge counter exactly like the battery capacity. So it can depend from many factors and isn't simply to understand how really battery life is.
Thank you for all of your support and answers !
Yesterday I installed Battery Guru 2.0 and seems a more decent app than AccuBattery, will keep monitoring
AccuBattery and Battery Guru 2.0 tell me that I only have 1598mAh.
Aida64 tell me 3504mAh.
I don't understand...
I only know that my battery life is poor. I arrive with 20% or less at 8:00pm.
It is also true that I have many IOT applications always active, as well for the smartwatch, wifi, BT and GPS always on and also Always On Display all the day.
Cheers.

DO not forget to check the dual cells in the settings of the apps (accu battery and battery guru)
But even so.... 1600 mah x2 => ~3200mah
Very very unusual for this phone and battery

Question How can I see the actual mAh of the battery?

How can I see the actual mAh of the battery in MIUI 14.0.8?
An app (smart charging) said 4080 mAh at 100% but I don't bite it, since i used it for awhile and stayed at the same numbers.
I can't believe that in one year it lost 20% of full capacity.

You can certainly lose 20% in one year. Heavily used Li's have a 1-2 year lifespan. At 80% of their original capacity they should be replaced to avoid a battery failure which can damage or destroy the device.
Any swelling is a failure.
Battery replacement is part of necessary routine maintenance. With most models is not a big deal if the tech knows what they're doing.
Any reliable way or software to measure it?
jeeesze, just replace the battery.
Why? I don't have a problem, other than a software that told me 4,080 mah. I want to double check it. As simple as that.
Large print doesn't impress me.
Hook a damn watt hour meter in series with the battery and fully discharge it from 100%. Then when you find the battery actually is degraded you can replace the $20 Li with a clear conscious.
Or wait for it to fail, my preferred scenario...
I don't know why the print is big. Haven't noticed until you wrote it.
