Greetings! For some time now, I noticed that my Redmi Note 7 lasts less hours with one charge (around 5 hours of SOT), and, maybe because I'm a little susceptible about these things, I thought I noticed that my battery got a little bulked, so I brought the phone to a little service point for smartphones in my town but they said they didn't notice it, so I thought I just got a little worried for nothing. But now I've installed accubattery, and during charging, the voltage level is around 4395v and is signalled in red, so I don't know if I should bring the phone to the official assistance or not. I don't know/I can't find information about the voltage supported by the battery, so I'd like to ask you guys who are surely more expert than me Thanks for any help in advance!

Hi there,
I have been the owner of a brand new M500 for just over 2 weeks now and generally I am very happy with it (although I haven't had chance to play with it too much yet). I am just a little concerned with the max battery charge...
After around 16 hours first charge I generally run it down below 1 hours worth of battery left before I put it on charge, always overnight (so getting around 6-7 hours on charge through power adapter not PC). However since the second charge (which informed me I had nearly 9 hours of battery life to look forward to) it has been steadily dropping by around 20 minute increments so that the last time it dropped just below 7 hours max charge...
So this got me to wondering:
A, is this normal?
B, should I expect this to level out at some point, and how many hours should I expect this to be about?
My usage of the PDA functions aren't great and so I generally get a good 2 days worth of use between charges (1 day if I listen to MP3s during the day).
I have disabled the Beam (IrDA and Bluetooth) and only activate them when I want to use them and I only have the screen on a medium brightness. I try to ensure that I don't leave programs running when I'm not using it... Is there much else I can do to increase battery life or should I be happy with what I am getting, as this is the first time I have had a Smartphone, I don't know what to expect...
Many thanks for any of your comments,
Dan
What are you using to tell you the remaining battery time? The standard battery app tells you remaining % of battery, any program which tells you the remaining time is estimating it based on this reading.
Most programs which do this use averaging techniques to find the best estimation of remaining time based on previous charging and discharging times. The reading on your remaining charge time will eventually level out after a few charges. The charge the battery holds hasn't changed, but the estimated time remaining based on that charge has.
Thanks for the reply, I was hoping that was what was happening...
Thanks for clarifying

Hello everyone.
(Please excuse my lengthy post, I had a lot of details to share. Thanks!)
So I recently bought N910C from a guy in Dubai, who gave me an extended 8500mah battery along with it, and claimed that it would last me 3 days easily (though later he claimed that it runs a day on full use, and 2 days no mild usage. Also claimed that standard 3220mah battery lasts less than 6 hours) but 8500mah would take around 6 hours to charge (it takes me 1.5 max, does 1% in a minute, with quick charger). I was however instructed to calibrate the battery properly, which I did, twice, tried the manual (draining and full charging) method, and also tried two apps: Battery Calibration and Battery HD.
Facts:
After buying, I flashed marshmallow stock rom for N910C and rooted with CF-Autoroot.
I have been using its own fast charger throughout, not the standard charger.
Here is the problem:
Before rooting and changing the rom, the battery was barely lasting and would shut down when around 30%. So I rooted the phone and did the calibration (manual+Battery calibration app), but the battery timing remained the same, or maybe increased slightly. The good thing was that it did not shut down at 30% and went down to 1%, where it stuck for good 15 minutes (with me browsing the net).
After I recharged it, I tried Battery HD app, which ran tests and gave me the following figures of battery usage:
30 minutes on internet: 5%
30 minutes on video: 6%
30 minutes on music: 2%
After this process, the battery again collapsed in its 30s%. I tried the battery calibration method again, but no luck now, battery collapses in its 30s. The guy who I purchased it from keeps sharing the snapshot and claims it was working fine before.
Now my questions:
I read some guides, including topics on XDA that suggested that Exynos drains more than snapdragon. So should I try to make a switch to a variant of note 4 with snapdragon, or would that make no major difference?
Is this battery faulty and I should change it? the Seller claims that he had to come on to an extended battery cause the standard was ****, so I shouldn't try and get another, it would be a waste.
What could be the problem if the battery falls in 30s% even after calibration, with exception to that one time?
Also, when it collapses in its 30s and I put it to charge, the screen shows "charging at 45%", why is that?
Lastly, I read here on xda that zerolemon extended batteries require the standard charger as the quick charger would give **** time and would charge them quickly. Will that apply to me as well? Although my battery isn't zerolemon, it's some unknown brand. And it seemingly charges quite quickly with the regular charger as well (when the phone is turned off).
He claimed that it should take my phone 6 hours to charge, it takes me barely 1.5 hours even on the extended battery, is there something I am doing wrong?
If you went through all of what I wrote, thank you for being so patient! So now, do I have any hope with this phone or should I just sell it off and maybe get an AT&T or T-mobile variant?
Thanks in advance for the guidance to come. I'll keep updating this post with whatever other tests I run, and the progress.

Sounds like the battery is faulty. ...try another one if possible

That's what I am trying to do, if only I can find someone's spare to try out lol.
p.s. you signature, lol I have the same three phones with the same status, except that my G3 (which is also white) is in a coma and G2 is up for grabs.

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.
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
