Interesting battery performance...

OK, I've had my HD2 since November, and I've never understood people who complained about poor battery life. I've consistently been able to go up to 2 days before charging. On the odd occasion, I've left TomTom running and it's drained the battery right down, but overall I've been pretty content with the battery performance.
Until about a week ago. I thought I'd maybe forgot to stick it on charge overnight the odd time, but now realise the battery has started to drain much more rapidly.
I did not change ROM, or install any additional software. I made sure nothing was running that shouldn't be in Task Manager. All of a sudden, I'm getting quite random battery drain - up to 20% drop in an hour. I put up with it for a week, thinking it just needed a hard-reset, so last night I decided to flash a new ROM. I updated to the latest radio ROM, and flashed bobsbbq's latest ROM thinking that would sort it, but after I took it off charge this morning it was down by 15% within an hour.
The drain has levelled off throughout the day, but it's still much higher than I'm used to. I don't use wireless, and I only have bluetooth turned on if I'm on AC power, so I've just got GSM/3G in normal use (and get good reception at home and work).
The fact that the battery drain changed so much in such a short period of time, with no obvious change in usage or software leads me to believe the battery itself is beginning to fail. I usually expect a good couple of years from a mobile battery before I see noticable drops in charge, but that's 6 months.
Is it possible the HD2 batteries are not very well made, resulting in some people having great battery life, and others complaining that it's crap?

I had read that some of the HD2 batterys were a bit dodgy as they were siphoning off the batterys from different manufacturers and as a result some are remarkably better than others.

I am precisely in the same boat. I am using my battery now for around 6 months. Since last week the battery seems to drain much faster than before. I am still analyzing what could be the reason, but I think it's the battery itself that is getting weak - far too early.

You said it yourself, the batterys performance gets worse for every day and should be replaced with a new one every 6 month, atleast.

Some feedbacks in other threads pointed out a possible and unforeseeable cause, the microsd card.
Try removing it and check battery drain, if that's the culprit try formatting it before throwing it away.
Also, as I stated in at least 3 other threads p) it's always a good idea to check battery drain with battclock, it should be 4mA during standby, any big variations from that mean something's draining while phone should be sleeping instead.

Yeah mate, that's laughable. I've never had a mobile phone battery go within 6 months. Are you trying to jump start your car with your batteries or something?

[Q] Is the battery gone or miscalibrated?

hello everyone, I'm a new note owner, I bought it used and I think it has two years on it, but it is in great shape. I noticed however, that the battery life isn't that amazing as people have told me, this coming from a Galaxy alpha user. I will leave screenshots of today's battery life and I think it isn't that amazing what it got
I've heard about battery miscalibration, is this really a thing? I can try and calibrated but I need to root it, & I wasn't really looking forward to reading it, since its lollipop on stock rom.
The screenshots are bellow of screen on time and total time, you can see that it's not consistent and I charge my phone two times a day.
http://imgur.com/a/ShaLI
I'm using lollipop official rom flashed on Odin via download mode, yes the rom is compatible with my country's frequencies so there's not really a problem there.
I notice however that the battery sort of goes down faster sometimes more than others, sometimes even going as far as draining 10% simply being on stand-by with LTE enabled for 2 hours in my pocket when I'm in class.
Is this normal behavior?

I don't think there is any such thing called miscalibration, I mean I am not sure, but well.
If your phone is 2 years old, then I think the battery has seen its life, time to get a new one mate.

Battery recalibrates itself .
However as the battery is old then Drain the battery to 5% power off charge fully unplug wait one hour top up charge and use .
Next step is new battery Anker brand is good .
Wiping battery stats/ supposed calibration has nothing to do with battery calibration and will make no difference .

Lithium-ion batteries last about 300-500 charging cycles, after that the risk of it dying increases exponentially. Some last 5 years, some 1. It depends on usage and environmental factors.
There is no such thing as recalibrating a modern lithium ion battery. It doesn't have a memory.
New battery costs about 20 quid, it should solve the problem.
Also, did you do a reset after the update? Updates can cause battery drain too, quite often.

No, I did not do a reset after the update. But I noticed this before updating to lollipop, I had to do some running around before I got home the day I bought it, and it was running KitKat 4.4. I got it with 93% of battery, walked home for a bit and was down to 65, went to the shopping and back, got home with 40 to 35%. (I bought the phone at around 5 pm and finally got home after going to the mall at around 8pm)

Then it's the battery, most likely.

Are these battery numbers normal nowadays? Need opinion/comparison with other users

Help me out here, I think my G2 which used to be a battery champ is now absolutely awful. I don't really know if it's the phone going wrong or my different usage and the way apps might have evolved.
I think the phone is also heating up way more than it used to do. In fact, I never used to notice the phone getting warm at all and never knew what people with SD810 phones were talking about. If I happen to run a game like Boom Beach or Fallout Shelter for 5 minutes, not only the battery suffers a huge drop, the phone gets almost uncomfortably hot (*). These games can kill the battery in 1:30 hours of SOT which I think isn't probably normal.
The numbers I now have to show are of the phone fully charged last night before going to bed, turning the phone off and then turning it on to clean running ups, etc and left idle while sleeping.
Went to bed with a full battery at around 4:30 AM and it's now 15:46 and battery is down to 64%. Turned the screen at 13:00 to see notifications and browse through news, made a single phone call that must have lasted less than 10 minutes. Pictures, although I think they won't help much except for the SOT:
I bought this phone used and I think it was refurbished. Came from Spain (I'm in Portugal) and happens to be an AT&T version. Screen was always a bit dark and a panel that I believe has been replaced. I think the screen is also going, sometimes it won't respond to touches on the far right edge.
I have it running on the official Lollipop firmware that I manually flashed (no OTA here) but I've tried different ROMs to see if they make any difference (Cloudy 2.2 and 3.3., CM13 and Blisspop Marshmallow). They don't, battery behavior is the same, phone heats up.
I need to know if this is normal for you guys still using the phone (software evolves and maybe things are more demanding on this old phone) or if something is wrong with mine. If it is, I need to think about sending it for repair (probably not worth it) or get a new one.
Not the best of times for me to be spending money on stuff like this but I'm really starting not to trust this phone, carrying the charger with me all the time and have a nasty suspetion screen might die for good one of these days.
Any feedback much appreciated!!
(*) Gets hot mainly on the top back, near the camera lens. Sometimes screen gets also hot but I think it might be due to heat transfer from the back.

I would replace the battery. Li-on batteries typically don't last for more than two to three years. Useful life span depends on how deep the average usage cycle is. I typically try to keep them from going below 40%. An old battery that no longer holds a good charge can cause similar problems. Most rechargeable batteries, including lead-acid automotive batteries in general, suffer from deep cycle charging.

Yeh, I know...
I tested it a bit more and at least now I know it is definitely draining way faster than it ever did and I don't see anything that is especially killing the battery (kept off games that I don't even play so much anyway). Oh well, time for a new one I guess. I have been postponing buying one until all these new 2016 main phones came out and they are all pretty much out already.

After running certain apps, or sometimes after connecting to USB in the car, the G2 will go into an overheating condition, with the battery charge rapidly falling. I just reboot it to clear it, and it's back to normal.

Tried that, even made two more factory re-sets. No good, same results... poor thing is going, I'm already convinced of that. It's draining about 1% per minute with screen on, regardless of what I'm doing. About 12% drain with it just sitting on my night table for 6 hours while I was sleeping.
Trying to find a replacement now which is driving me insane.

Well, replacement batteries are a lot cheaper than phones. Why not replace the battery, and squeeze a little more life out of it? Would also serve as a backup phone after you do get a replacement.

I'm pretty sure battery isn't the only thing going bad, screen sometimes doesn't respond or respond weird. Mine is already a refurbished unit that I bought because it was the best, cheapest and quicker to get phone after drowning the one I had before. It's not factory refurnished though, some guy in a shed did it. Worked very well until now though but I prefer just to get something that is new instead of paying for the repair of one thing and having another breaking the week after that.
It's going to be either another G2 (found one that seems to be an unused unit but seller hasn't got back to me yet and it would cost pretty much the same or less than a battery/screen replacement) or I'll just get some other recent flagshipy phone that will allow me not to think about phones for at least the next 3 years. Not really sure what that would be but hey..

Question in regard to degrading 6p battery

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.

Battery issues, confused.

6P has been shutting down early for a while now, usually like 10% or less which never really bothered me. Battery life seemed decent, but I never really tracked it.
Last week it started going off at 15-30% at times. But it can be random. Might go below 10% one time, next shuts off at 30%. This was on a prior version of Pure Nexus. So I tried updating to the latest build. First charge it shut down at 40%. Same crap tho, random shut off times. Today it shut down at 48%. By shut down, I mean it just suddenly gives the low battery warning, reports 0% and turns off. Many times I can restart the phone, and it will say like 1-3%, and let me use it for a while before turning off again. This most recent one at the 48% shutdown, I restarted it, showed 1%, used it for a while before it turned off again. Restarted, now shows 18%.
Wtf? Is this just a charge level reporting issue? Tried battery repair/calibration apps/techniques with no success. Nothing looks bad with regards to apps/services draining the battery. I tried accubattery and says I'm at 70% health. Don't even get 2 hours of SOT. Have a replacement battery in the mail. Think this will solve the issues?

It's known issue with some factory battery's for some reason the phone is thinking the battery is low and shutting down even though it's reporting let's say 50%. I didn't have this issue until I bought a cheap replacement would shut down at random percentages especially when opening something power hungry like camera. The only thing you can do is get a replacement and change or send it in to get changed. If you replace it yourself I suggest testing the battery before you put the phone back together. I think the 6p is a great phone and worth it to replace the battery. That just my opinion best of luck. ?

@ 70% your battery has been toast for quite a while. This degradation doesn't happen overnight. If you did your research and purchased one of the "good" replacement batteries from a known good vendor then, yes it will likely completely solve your problem. If you just bought a random battery from Ebay or BFE, then you may have another dud on your hands. Suggest testing the new battery with Accubattery before sealing it back up. Best of luck.

Interesting. Did notice a couple of the times it shut down, and it was this last time at 48% as well, was when opening a power hungry game. And yes I agree the 6p is still awesome today, by far the longest I've had a phone. Considered getting the Pixel 2 XL, but it's a waste of money to me if I can get the 6P working well again.

@ 70% your battery has been toast for quite a while. This degradation doesn't happen overnight. If you did your research and purchased one of the "good" replacement batteries from a known good vendor then, yes it will likely completely solve your problem. If you just bought a random battery from Ebay or BFE, then you may have another dud on your hands. Suggest testing the new battery with Accubattery before sealing it back up. Best of luck.

Hmm, yeah I grabbed one off ebay. Had over 500 sold though, so hopefully not too terrible, but I will test.
I think it has really degraded in the last ~6 months. Possibly from numerous partial charges? Got a new job in April, and I'm often traveling to different sites only 10-15 minutes apart. During this time plug it into my car for Android Auto.
Thanks for the help guys!

In the same boat (But I have a solution for me)
2 weeks ago I upgraded from a beaten GS6 Edge and I am quite fond of my new phone. However I started experiencing this issue, ignored it for the first week since my S6 at 100% battery would die in an hour or two, if I'm lucky. Then the battery problem became an interest to me. I had read a lot of threads on the issue, some saying its a hardware problem, and some saying just a software bug that hasn't (or can't) be fixed. SOOOO at this point I said screw it and just accepted my phone battery as it is. Installed Dirty Unicorns Rom, messed with settings, and boom a breakthrough (I think). DU has a feature called smart pixels in which to save battery life turns off a percentage of the pixels. Wasn't to fond of this at first, but in order to make my 60 - 70 percent battery last i set it to the lowest setting. Every since then I have had maybe one random shutdown, it's only been a week and a lot could change but for me its working pretty well.
Sidenote: I found that not using camera apps, nor Google assistant had also prevented random shutdowns (this helped me with smart pixels enabled and disabled, if you wanna give it ago on stock)

Hello guys. I am experiencing random shutting downs on my phone too. I bought it in January 2017.
What I have observed and today was confirmed is that I have these unexpected shutting down when I charge the phone with fast charge. Today my phone was at 60% and shut down. When I plugged my phone on the charger, the phone was again at 60%!!! How was it possible? I think the problem might be the battery or the internal controller of the charging system...
