Hello to all,
I just purchased a brand new Nexus 6p that was purchased about two years ago directly from Google. The individual bought it but never even opened up the box so the phone has never been used or even turned on until four days ago when I got it. My question is this. Even though it's still a brand new 6p can the battery still degrade even though it has never been used before? My first thought would be no because the battery has never been used meaning no wear and tear to the battery even though it's just been sitting there unopened for two yesrs but then I got to debating this with myself and I just don't know the clear answer. Should I be okay in terms of the degrading battery issue since my battery has never been used before? Any help is greatly appreciated.

Battery degradation occurs through it's lifetime of charging cycles due to heat (and chemical changes within the battery). Since your device has not been subject to this, it should be like new. Note there are literally thousands of N6P users who have never experienced battery degradation (or bootlooping). We have 3 in our family and none have been affected. I suggest you just let the phone charge and discharge normally a few times before you start forming any judgement on your battery life or SOT. Install Accubattery and check the battery health after several deep charges. After several full charge cycles, Accubattery will estimate the capacity of your battery vs. a new one (3450 mAh). Enjoy your new 6P. It has been a great phone so far (knock wood).

I appreciate the clarification on that. I wasn't sure when the degrading process started on a battery was. I love you this phone. In fact it's my second time owning it and by far it's my all time favorite Android phone I've ever used. I'm glad to know my battery should act as new and I should be okay from the battery issues. I appreciate you explaining in detail to me about what to do and how to check my battery life. I'll download that app now.

Okay I just downloaded accubattey. Now once I charge it for a while I will get results about the health of my battery. What do I need to look for that's tells me it's good? Any tips on using the app. So indeed I never should charge past 80 percent? I always have charged to 100 percent so that's going to take some getting used to. Also I don't need to let it drop below 20 percent? Thanks again for your help on this. This is all new to me as I've never had to guard against a bad battery before nor have I ever had one. I hope my new 6p will be okay. So far it's seemed to have kept a good charge but I'd of course like to see it do a little better being that it has a 3450amp battery inside. There have been a couple times of times where it seemed to eat up battery life quickly but I found out I had some apps running in the background such as YouTube once where it consumed 77 percent of the battery overnight once but I have since fixed that. It hasn't happened again so I'm good there. Anyways just curious to know what I need to be looking for on the app. Thanks a lot!!

I've always charged my battery to 100% and will continue . I leave it on the charger at the office and home, all night long 24/7. When I leave the house I want to know it is 100%. One thing to note is that you should not take the phone off the charger until the APP tells you it is charged, not the phone itself. You will see current flowing into the battery sometimes 45 minutes to an hour after the phone says 100%. That, and let the phone drain down to below 20% first in order to get an accurate charge measurement. After that you look on the health tab for the estimated capacity. It will be provided in both mAh and percentage. Quick Start guide here.

So you actually charge your battery to 100 percent. I guess I will do the same since I'm used to doing it that way plus I want that extra 20 percent charge. This seems like a really good app. I appreciate you guys on giving me the heads up on it. I downloaded it to both of my devices which my daily driver is the axon 7 mini. That battery isn't the best so maybe this app will help me tweak that battery into keeping a longer charge. I like a smaller device to be my daily driver although for right now my 6p is my daily driver just bc it's new but after a couple weeks I'll swap back over to my axon 7 mini as my daily driver

Yeah, I disable that 80% charge alarm first thing. Accubattery is just a tool and it's just giving you an estimate so don't rely solely on it. I will say that after a few full charges it converges to one percentage value and for me that has been enough confidence that my battery is not in a degrading trend (so far). There are a few Accubattery haters out there but it's been a solid tool for me. Enough so to buy the Pro version. Good luck to you.

Much appreciated! Yeah I think I'm going to be fine in regard to my battery. I mean it's brand new so there has been no usage of the battery until as of about three days ago. I'm super excited to have gotten this unbelievable deal I got on my 6p. Never in a million years was I expecting it either. I got in touch with this guy by chance. There was never any intent on getting a brand new Nexus 6p for 150 dollars but by the end of our conversation that's what he offered me. Just a very generous guy.

I've never seen this before, but it's quite amusing..
I bought a spare battery (the giant extended UK eBay one). I used it all day yesterday, and just swapped in my normal one today. It should have a full charge. But the battery meter is reporting 21%.
Well, it WAS reporting that. 5 minutes ago it was reporting 32%, and now it's reporting 40%. Interesting stuff to see, for sure!

Its allways happend with android, if you switch batteries you should clear battery stats in recovery and it wouldnt happen
that's why i don't recommend frequent changes in battery unless in emergency situation because the device gets confused with the stats.. it's good to have one spare batt, but it's a lot better having a travel charger...

Yeah this is pretty much for high usage days, but not everyday usage. I see valid days for a battery swap once or twice a month, so the backup battery will really come in handy.

It may be confused but it's not bad for it. I have 3 batteries which I cycle. Sometimes it just up and shows the actual percentage, but other times it slowly increases until it gets to the right spot. That's it, it's not tearing down the space-time continuum inside the phone.
Didn't find a main thread for silly questions such as this so hope it wasn't wrong for me to post this here, but I currently find myself in my phone going as low as 50% on a daily basis and I charge it next day at not lower then 40%, will this wear out the battery? am I really supposed to charge it when it's really low? Thanks.

The latest in Li-ion batteries, as the one in our phones, one duty cycle is when you use 100% of the charge.
That is ifyou go from 100 to 0 that's one cycle.
If you go from 100 to 50, recharge and again 100 to 50, that's one cycle.
Batteries wear out depending on the number of duty cycles. More duty cycles, more wear.
So what you are doing will not wear out the battery.
Also I'm not sure about this, but it is recommended that newer batteries should not be completely discharged.
Please correct me if I'm wrong, anyone else who can confirm.

Modern batteries are not like older (10 years+) batteries. I'm not about to write a wall of facts here etc. etc, but I only have one thing to tell you:
Use your device, and don't worry about the battery. It'll do just fine until the day you decide to buy a new device. Now stop worrying and just use it.

Same here, these batteries are tough. I am anal about my phone battery being charged. Haven't had an issue for years and I expect the same performance out of my S7E
Topping up your battery before it is fully discharged is the best way to extend your battery life. Modern batteries run best between 40%-80% charge. Minimize the number of times you fully discharge the battery as that is more likely to wear out the battery, although it is ok to use it until the phone shuts off once in a while.
Very impressed with the battery of the S7E. I charged to 100% last night and didn't charge until just an hr ago and was at 47%. Normal use in the morning til now. In n out of meeting, so its doing its job.
Now back to the topic of this thread, i've read some say these newer batteries should be power cycled at least once a month. Any one recommend that or against it? Haven't done it myself but did it a few times on my iPhone 6 Plus and that thing had an awesome battery even though its actually smaller than the S7E. Thoughts???

I've seen it recommended as often as once per month or as infrequently as once every 3 months. The general consensus is that it can be beneficial in that it can correct any issues that the phone software has in determining the battery's capacity, not that it is actually helping the battery itself.
Yup, I did that once in a while with my previous device (a Sony), and the battery on that one is still very good after nearly three years. I wouldn't do it that often though, but it's useful to do it when you notice the battery meter hangs on the lower numbers (like if 10% hangs for an unusually long time) or you've just flashed a ROM. The OS tends to get a little confused after some time, so it's okay to do it to "calibrate" the system again.
Thanks for the helpful replies guys.
Draining a Lithium battery to zero is one of the worst things you can to an Li battery. Don't do it. Period. Ever.
Yes, don't power cycle a battery. It MAY help give a more accurate battery reading, but it's messing up the longevity.

Hi all,
Recently I have exchanged a battery at a local service provider, battery they showed before installation seemed as legit as they come and after replacement phone felt way more agile especially at a lower battery charge levels. So I was happy until I started investigating poor SoT that I thought at the time was due to the Oreo update. After some time, resets and reinstalls it feels like the system is as healthy as it can be for now, but Accubattery shows 83% health at 2,853 mAh out of designed 3,450 mAh. That is only after few charge cycles, but I am still worried that it might a permanent battery hardware issue. Right now at latest Oreo build with elementalx kernel running a wingoku gov profile I get around 3 to 3,5 hours of SoT with little use, over night after 100% charge phone looses around 10% percent by the time I wake up.
If anyone has any insight into similar issues and can confirm Accubattery health stats credibility I would really appreciate.

Sorry, but you got a bad replacement battery. It happens. Although it just provides an estimated value, I've found Accubattery to be a very solid indicator on the phones I've used it on. Since your battery is barely above 80% it takes the guesswork out of the equation. The battery capacity estimate converges quickly to a value after only about 3-4 charges. That's it. It's not something else with the phone. It is the battery itself. There are literally dozens of threads discussing which batteries are good replacements and from which sources. Buy one of those and your problem will be solved. There are some Accubattery haters out there, but I guarantee based on what you are saying, your battery is a dud. With a fresh, high quality battery you should be seeing very high 90's to low 100's. Yes higher than 100% because some batteries sold actually have a higher capacity than rated. Try to get one of those.
Thank you for a reply.
At this point I guess I will just have to live with it until I buy a new phone, I only decided to give this one another go since I love it and do not see anything on the market now that would appeal to me as much as 6P did at purchase. But I do not want to spend more money and time on this, just wanted to make sure this is not a software issue. Software I can tweak, but battery replacement yet again is too much.
Now the question is, can anyone install AccuBattery and let me know after a couple of charges (needs to be charges larger than 50%) what your battery health says it is?
I expect your response to be delayed by days obviously, but if you can confirm below that you are doing it I will appreciate it.
I'm starting to think that I got a lemon, the SOT is obviously different from anyone else but this is the first time that AccuBattery tells me that my battery health is less than 100% on a new phone, and when I get less SOT on such phones AccuBattery correctly confirms my suspicion every time (sample size 5 phones).
For visibility of everyone, hence the question, I want to see if this normal for this phone or just a defective battery.

I got the same thing with the OP 6, the battery capacity mah was 2933 instead 3300, 6t says 3378 instead of 3700. I don't believe it's accurate. Just did my first full charge charge after I got it Monday. Battery seems solid. Ampere says Max Capacity 3700
Says 3388
But my battery is solid
Will test with a device soon and see if it is accurate or not!
93% here. 3,437 out of 3,700 based on 7 sessions with 174% charged for a total of 5,981 mah total. I received the device on the 2nd.
Here's mine. I got mine yesterday.
same here - 3450mah by accubattery. my 5t shows 86% 2850 actually.
pixel 3 (not xl) - show 99% as specified =\.
is that means 1+ lies to us?
I was literally just looking at mine last night. Gotta say I'm a little confused... No way a 4 week old phone should go from 3700mAh down to 2915mAh capacity...
Mine is down to 3300. Either AccuBattery needs an update for the new OS, or the background battery optimization is playing with AccuBatter readings?
Or maybe we are getting weaker batteries but I hope this is not the case.
most of us seem to be around 94% give or take. Maybe it's the app, maybe something else. As long as we are getting those awesome SOT times everything is good and we should not worry too much.
I have been using Accubattery since my Oneplus 5. On my brand new Oneplus 5, Onplus 6, and Oneplus 6T - they all started out from day 1 at about 93%.
Either the batteries are starting out a bit lower, or Accubattery isn't accurate.
My note 9 was always less with accubattery too
This same exact issue was reported with the 5T here: https://forum.xda-developers.com/oneplus-5t/help/battery-health-accubattery-t3735499
The application is not accurate.
Edit: Sorry about the necro...I was looking into this issue and was glad to find someone talking about it and wanted to contribute.
New phone and mine says:
Mine says 89%
4906/5500 mAh
Based on 6 sessions with 283% charged for 13883 mAh total.
I was kinda wondering how accurate it was too...I know it has to use some kind of modeling, instead of measurements, to get those numbers...but I was kinda expecting it to be more accurate...apropos of nothing I guess.
I stop charging around 85% (missing a couple times and 100%ing overnight), but other than that, I dont push it hard.
I had the same issue..
charge your phone one time up to 100% and then leave it on charger an additional hour. you will see, your battery health goes up to 96-97%.
Ignore these stupid apps that measures your battery health. They can't do it in a reliable way anyway.
As a bonus if you don't worry about this false information you'll live 5 years longer, good or bad, you decide.
Tbh I given up on my battery health for my 6T. A phone is suppose to be used. Just trickle charge it (Charge it bit by bit). Avoid charging over 90%. It doesn't matter if your battery health is low or not. If your battery life sucks two years later, you can just go to Oneplus support and replace the battery. It may cost more than a replacement battery, but it guarantees that the battery is new (not a year old) and you don't damage your phone. Sorted
Bought a used LG-AS993 and the AccuBattery app says that it's battery health is at 85%. So instead of a 3,300 mAh battery I'm working with 2,808 mAh. I'm wondering if there's a more accurate way to test it or if I should return it and get a replacement.
Any ideas?
Thanks,
DJ
I dont think AccuBattery is absolutely exact. See it more like a hint of the actual state.
My G6 battery state was 108% after the first charge, and quickly dropped to 96% after 10 charges. Even if the phone was brand new.
My LG G4 was quickly reported as 82%, even if i have an LG guaranteed original battery manufactured 4 months ago.
So no, i wouldnt change it yet.

I think you are right because after a year of relatively heavy use my battery is still as brand new which can't be right.
Also just keep in mind that an OEM replacement battery is approximately $10 on Ebay right now. So you can worst-case just swap to a brand-spanking new battery, assuming you are OK following directions for pulling off the back plate using a heater (see youtube videos for battery change LG G6).
I have noticed that the less you charge, the less accurate the battery health function seems to get.
If i charge only 20% a couple of times, then the health percentage will drop. And if i charge it from 25% to full the health percentage will rise again.
If the battery charge recommendations are followed ( 40% - 80% charging every time), then the health numbers seems to become more inaccurate.
Quite understandable since it is easier for the app to calculate the health during longer charge sessions.
But at the same time counterproductive since the best way to get a long lasting battery is to charge 40 - 80%.....
So.... forget about the health tab, just charge it to maximum 80% and the battery will last longer than the phone....

I think that's good advice, to forget about the battery health, for two reasons: 1) Why would you even trust the "health" judgment provided by the app, which is demonstrably unhelpful and imprecise, and 2) Why invite more worry and stress over the battery which decreases your enjoyment of the phone?
Maybe we could also discuss the general schools of thought about the pros and cons of worrying about battery health.
But overall I feel like you should weigh and compare the benefits of worrying vs the benefits of not worrying. I mean, the way I think about it, is that if you apply the absolute worst treatment and abuse to your battery, you are *STILL* going to come out in a better situation than if you try to worry about the battery health.
For example, you incur a definite cost by adding extra hassle to your life of trying to just charge to 80%. So you get all the hassle, but what do you gain for all that hassle? Have you quantified what gains you get, after 6 months, after 1 year, after 2 years?
The tiny gains you enjoy after 2 years are *NOT* worth 2 years of extra hassle.
Couldn't have stated it better.
BTW I have used AccuBattery on a new tablet that I have, and it also gives variable results that aren't very helpful.
So I agree. Just enjoy your device and don't bother with these apps, unless there is some real problem to diagnose
