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?
ok, I have my Nexus 4 since launch (yes, the very first batch), it has been a great phone for me and my wife sometimes.
The problem is, last january, i noticed my battery just didn't last as before, in a couple of weeks it just "died", so I replaced it with a "genuine" LG battery from eBay, so my problem was solved, but it never could reach 100% full, after a full charged, after unplugged it just dropped from 100% to ~85%. but i could make it all day without the necessity to recharge it during the day.
Just a few weeks ago I noticed the same problem as before, it has been lasting less each day.
so my doubt is: is my battery defective again? or could it be another hardware issue?
So I have been trying to figure this out for a month now. My wife has been complaining that her S5 was draining the battery by the time she got home from work. This started happening after the latest update at the end of June. So I thought it was the update but my s5 has been fine with no problems. After uninstalling some apps and setting the location settings to power save it was still doing it. So I reset her phone and installed some of the standard apps she uses which are the same as I use so I knew those were now power causing the drain. Well it was still happening and her usage is not extremely high, it is pretty much the same every day. So two days ago we swap batteries and all of a sudden her phone is lasting all day and into the evening for the past two days. Now her is the kicker the night we switched batteries I noticed that my phone was using a lot of juice for not doing much and by the time it was time for bed my phone was beeping that it needed to be charged. So at this point I figure her battery was shot. So I charged up my phone that night and the next day I have not seen any serious drain, just normal battery life and it is lasting all day like last night it was at 45%.
I was going to try an experiment of putting her battery back in her phone and see what happens but I have not had the chance yet.
Anyone have any idea what the issue could have been? Seems unseating the battery and reseating it might have fixed the problem but it doesn't make sense of why.

So a quick backstory on my S7 edge experience. This is my second go around with the S7 edge as the first was plagued with bad battery life and sluggish if not defective overall experience. Two days ago I decided to jump my S6 edge + (great phone) for a S7 edge ....again. Wanted to see if something was different as all the rave reviews could not be wrong and maybe I just got a lemon. Well low and behold I again started to experience strange issues with the S7 edge such as:
⏺Bad battery life ( less than half a day with moderate use)
⏺Strange notification bar message (call forwarding for video calls active)
⏺Sluggish performance
What was causing this Strange behavior?.....
Turns out it was most likely caused by a bad car charger which overheated the charging circuit or some aspect of the phone. Must have happened the first time and never realized but the second time I put two and two together. Lesson learned her is if you are not seeing any increase in battery percentage while rapid charging and the phone is getting hot ...you may have damaged the phone and have a bad charger. Currently this is the 3rd S7edge and it is rapid charging cool to the touch.
Hope this helps.

Sir , Did your android system appear on top of your battery usage as well?
I had the same 3 symptoms but I solved my issue with doing a factory reset and starting my phone from fresh, now my battery is back to lasting more than enough for a day, 5+ hrs of SOT average since I did that.
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.

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...
