Guys what the hell, why this phone and Nexus 6p drops 2% of battery pratically every time? Some users says that the fault is of Doze, and some says that is bad battery. Just answer three things
[Question 1]
This problem is a software based or hardware? And if is software, there's some how make it stop doing this? It's annoying and makes me sick with the time of usage .
[Question 2]
Why in the hell some users have this issue and some not? That's a russian roullete? Really I'm mad.
[Question 3]
Are you getting this problem? Already solved this? Suffer yet with and doesn't even know how to troubleshoot this?
GRR really. I'm mad. And seems that happens on the same percentages, 99% to 97% 95% to 93% 90% to 88% and there it go...
note: When the phone is under 60% to 100% it stay in a temperature of 35ยบ, and you feel your phone a little hot, but when it arrives at the 50% ~ 60% down, it seems to be a little less hot, is that the processor's core being shutten down in order to give priority to the battery?
REALLY I can't understand the behavior of this phone. It's really strange, and how I never had one, I have no parameters to make any comparison.
It doesn't seem to be set at certain percentages but rather starts at where the battery is when you go there and then goes down by 2% at a time. I've never sat around and watched it before and it certainly doesn't irritate me. I have a one percent battery on my statusbar I can watch if I need something more accurate.

Hey all, so I have a different theory on the GNex battery issue but I'm not sure how to test it. It also might explain why there has been such a discrepancy in people's battery stats.
My theory is that there is something wrong with the way ICS/GNex is charging/reading/identifying battery information. Here are a few of the reasons why I think this is the case.
1 - My phone will occasionally charge absurdly fast, like 20 percent in 10 minutes... but then it will die equally as quick. My first thought was that the phone just charges and discharges quickly... BUT
2 - After charging for, say an hour, when I do a battery pull and let it sit for a minute or two before putting it back all of a sudden my super quick battery charge to 62% is now only at 37% (actual numbers that happened to me tonight). So why did I do a battery pull...?
3 - Because I noticed that after 10 minutes my phone had gone from 62% to 56% and I thought that was absurd. Once I did the pull and was back to my (as I like to call it) normalized battery percentage I have only dropped 15% in 2 hours and that includes heavy data usage on maps, navigation and texting. And another strange thing
4 - I have actually seen it go the other way! I once was around 30%, rebooted the phone and it jumped to 50%. Now that I'm thinking about it I often see weird fluctuations in my battery reading. One minute it will be 28%, then I turn it off and turn it back on and it will be 29%. Oh... and for those of you wondering
5 - This has happened both on a stock rom, rooted stock (although not like that would make a diff) and a custom rom ARHD. But still there is one last question...
6 - Why is there so much disparity on the issue? My theory is because this battery madness is so unpredictable you, you don't know when you get a normalized charge or an inflated charge. And lastly...
7 - I think it's gotta be a SW issue, why else would Nexus S owners be seeing the issue as well? (So that's good news... hopefully).
Soooo, that's my little rant. I think part of the problem is people are getting distracted by all these other theories with kernel drivers and etc because of the absurdly high Android OS issue (although in all fairness my theory could be more misdirection).
So why post? Well if people could try their luck validating/disproving my theory I would really appreciate it!
Here's what I'd like (and what I am going to do).
Charge your battery for an hour, if it charges really fast note the percentage.
Optional: Play with the phone for a while and see if it discharges quickly.
Do a battery pull, let it sit for a sec and put it back in and note the percentage.
If the percentage is significantly lower (10+%) start using the phone now and note the time to discharge.
Thanks!
EDIT: Also a good thing to mention, I am not disagreeing about the Android OS bug - I think that's also very real and something I have experienced as well. BUT if you look at the other battery thread you'll see a lot of people posting battery success images with high Android OS utilization. I think it could be an indication of multiple issues contributing to a negative experience.
Oh and I submitted a bug report to Google.

I've also noticed crazy battery drop after reboots or pulling battery. Easily drops 10%+ at times. Reminds me of my great blackberries back in the day

all good here. i'm very pleased with the battery life.
while there may be issues with the stats, the wake times are real for some users - as well as the heat generated (indicating the cpu is working) when the phone should be sleeping.
There is no question there are either bugs in ICS that cause wake locks to get stuck, or badly written apps that keep it awake that didn't keep awake froyo/gingerbread.
Agreed on the wake lock. In fact I really should have quantified that in my original post - I too have that ridiculous Android OS utilization.
I updated my post - you make a good point.
Charged to about 21%. Pulled battery and rebooted and reported about 31%. Running ARHD.
EDIT: Pulled battery again and rebooted and reports 20%.
I realized mine was charging extremely slow so I decided to turn it off and let it charge faster. It was only at 48% when I turned it off but as soon as the battery indicator showed up with the phone off it appeared to be well over halfway charged, I would've guessed close to 75% but I didn't think to turn it back on and see..
edit: I did charge it fully with the phone off then wiped battery stats in cwm before rebooting into the OS after this. Since then it seems to be charging normally and reporting the correct battery level
To prove this theory, I think you should check the reported voltage of the battery and compare that to the percentage meter. Most battery apps/widgets use the old Android "battery info" screen to report this data. There very well may be a problem with the GN/ICS meter, but to be sure there has to be some constant to go back to.
These batteries drop like a rock from full charge to something like 87-88%, and again from around 37-38% to zero. It's just the battery technology, perhaps exacerbated by not having enough battery stats to adjust the % meter.
As far as I know, an app/widget that reports battery voltage will do so from the information being provided by the battery circuitry itself, so it's not subjective or adjusted in any way like a meter will be, making it a far better correlation point for the discussion.

I use current widget to tell me my voltage, as I don't pay attention to the meter. On a stock LTE battery, you should cap out at 4.203V
Voltage meter sounds like a reasonable way to approach the problem. I'm definitely not an expert on battery stats though - what should the voltages read? I know it caps at 4200mv, but what is the min?
Also how does mv relate to mah?

mv stands for millivolt which is a measurement of voltage. Examples you may have heard before are 9v battery, 110 volt wall outlet.
1mv = 1/1000 volt OR 1v = 1000mv, so you can see a mv is very small compared to a volt.
mAh stands for milliampere-hour and, in layman's terms, is a measurement of battery capacity, specifically how many hours a battery will last if the device it is connected to pulls a known amperage.
So, if a device pulls 500mA and the battery is rated 2000mAh, then generally the battery will last 4 hours (2000mAh/500mA). There are numerous other factors in the equation such as temperature, age of battery, etc. that can affect the battery life.
Anyone experience this before? Lots of spikes and falls throughout the day. Look at my battery graph, it almost seems to be charging itself at times (especially around the 30% mark). I notice it goes up when the phone is in deep sleep, but when I use the phone, even with light use (texting), the battery drops quickly. About 1% every few mins. Then the battery starts going back up again once it idles. However, I'm still getting decent screen-on time, so i'm guessing its just the way my phone is reading the battery levels?? I'm certain its not an ICS issue either, as I saw this happen on GB a few times. This comes and goes with any warning and I can't seem to replicate it on demand to figure out the issue.
I'm going to try this calibration method and see if it helps: http://forum.xda-developers.com/showthread.php?t=1312273
My battery life suddenly became horrible this morning. Normally I unplug my phone every morning around 6AM, and i dont need to charge it again until closer to 9PM.
This morning, I realized that despite being on a full charge at 6AM as usual, my battery was completely depleted by 10. I checked the battery "app" and it said that phone idle and cell standby were both at 13% usage, and that was the most i had used my phone. it registered the full time (4 hours) of usage for those 2 but it also said that it was only responsible for 13 % of my battery drain each. After that there was google play services.
I figured it was just a fluke, so I reboot the phone and recharged it. Once again, the battery drained in a mere 4 hours. This time it told me a voice call of only 10 minutes length was responsible for 35% of my battery drain, and that having my screen on for a seperate 10 minutes was responsible for 25% of my battery drain. This might be fine and dandy if the actual draining chart showed a steep fall off when i made the call, but that is not the case. the chart is a straight line showing constant drainage with no steep or flat areas. I'm thinking something is definitely wrong and the phone is causing itself to drain. maybe something hardware oriented, since i dont even have very many apps downloaded.
I've literally only interacted with my phone maybe 3 times today, and I didnt even do anything major.
Do you guys have any ideas as to what is going on with it?
I'm CM10, latest stable. not the monthlies. no cpu hacks or anything, and as I said, this problem cropped up this morning. before this everything has been fine.
Please search for Better Battery Stats here on XDA. That thread has quiet a few tips on saving battery drain.

If I hadnt already made sure I was following the tips and I wasnt dead sure that something was the problem, I would not have made this post.
I did manage to figure out the problem by sheer dumb luck and a little bit of educated guessing.
I uninstalled the MyFitnessPal and tried again today. I'm exhibiting normal battery drain now (10 hours and im at 46% with not too much usage of the phone).
If you read the post I made, no apps were showing up as a large battery drainer, and all my stats were reporting incorrect times (13% battery usage for a 4 hour period despite showing me i only used the phone for 10 minutes). So something was definitely wrong. Uninstalling the app fixed the issue though, so for anyone who exhibits this problem, uninstall whatever apps you most recently installed and do a reboot.
I didnt have to reset or anything.
I know this forum is rife with battery questions, but ironically it makes it harder for me to search for the answer to this..
I've had my 360 for a week or so now, and the battery's actually been much better than I expected.... until today. Today, for some reason, my watch JUST died at 4:30PM (I've been making it to 10PM with ~20% battery). id idn't do anything differently. When I saw it was at 6^ or whatever it was, I looked at the battery stats on Android Wear on my phone, and it showed the graph going from 100% to 0% pretty steadily throughout the day, but the statistics only account for like, 35% of the loss. Like, bluetooth was 8%, Android Wear was 6%, there were a few random things at 2% and 1%.... and it all added up to 35%. Where did the rest go? Is my battery in a funny state, and if so is there a way to "reset" it?
Thanks all.

Don't know about missing percentage, but I've noticed that about once a week my battery doesn't last the whole day. I've found that restarting the watch once a week helps.
Hi guys,
I've recently bought a Nexus 5X. Naturally it came with Marshmallow installed. When I turned it on it was at 19% and I've used it for a couple of hours and the battery charge barely dropped, I was even concerned that there might be an issue with either the battery, or the phone reporting the charge properly (it just looked too good to be true).
I've charged the phone and updated to Nougat. It seems like the battery is discharging rapidly. I've followed tips like never let the phone go under 10-15% and charge for 2-3 hours longer, after the phone reaches 100% for the first few charges. Now on its 4th charge it still drains rapidly fast. When I use the phone (adaptive brightness off, I'm using it at 20% brightness at the most) and the battery drains really quickly and it looks like the screen is at fault. When I play something it's ~1% per minute or two, which is awful. Here are some screens:
It seem like I don't have enough posts in order to be able to post links in my threads, so the phone's charge is currently at 27%, the screen has used 22% of the battery - Time on: 2h 58min / computed power use: 567mAh
As a comparison my crappy old Sony M2 Aqua (I know, I know...) for the same battery usage by the screen I can see more than 7hours "Time on". I know we're talking about different devices, Android versions, screens, etc, but it still looks like the battery of my Nexus 5X is draining a lot faster than it should.
I must admit that the battery barely drains when the phone is at standby (locked screen).
So is this a software issue with the new OS, or a faulty screen, or battery or something else? I'm really freaking out guys, please shed some light on this if possible.
