Hi everyone...
First off, a little background.
I bought my Galaxy S6 a couple of months ago. Battery life on it was fantastic... overnight, I'd drop maybe 1-1.5% per hour.
Then I bought a Zenwatch, which I absolutely love. What a great accessory! Unfortunately, its had a fairly negative effect on my phone battery life. Now, overnight, my phone battery will drop 3-4% per hour. Doesn't seem like like a lot, but over 7 hours, thats a difference of 15-20%.
Last night, just for kicks, I turned off bluetooth on my phone overnight, and it returned to 1-1.5% per hour again.
Is this normal behavior? I thought the fact that it uses BLE should really make this a non-issue.
(Yes, it could be a non-Zenwatch issue, I'll be trying other things over time... just thought I'd start with what seems most obvoius)
Thanks!

So, my phone's battery life is overall quite poor for the most part. some days it absolutely burns through my battery with little phone use, and other days it gets decent battery. i downloaded better battery stats, and for example. today my phone drained at about 10%/hour, but yesterday for example it drained at about 3%/hour. And today i did not even use my phone that much. Please help, as this is getting really annoying.
Here are some screenshots of my battery stats on two bad battery days

I know it looks like dolphin burned alot of battery, but that it just because it was practically the only application i opened and i used it for a couple minutes which i normally wouldn't do. then i few hours later, this was where my batter was at, and i swear i pretty much did not even touch my phone at all! http://imgur.com/NIfYnkl

Yeah I noticed something interesting as well. I have two batteries for my GS3, one is the stock battery that came with the phone and the other is a 4200 mAh battery from Hyperion Electronics. I decided to test each battery by charging each to 100% on different nights and not touching the phone overnight to see what my battery drain was
Night 1, I tested the stock battery and over night I went from 100% to 40% in a span of about 8 hours. That's a 60% decrease.
Night 2, I tested the Hyperion battery and over night I went from 100% to 98%. A total of 2% decrease in the same span of time.
Now yes I understand that the Hyperion battery is essentially 2x the battery capacity as stock, but just by simple ratios you'd think that since the stock was a 60% decrease that the Hyperion battery would be a 30% decrease, but it's not. The Hyperion battery is literally 1/30th of a drain than was the stock battery.
Something's wrong here and I wish someone could give a straight answer as to why these two batteries are demonstrating dramatically different results.
I have this case:
http://www.amazon.com/Google-Nexus-2013-Case-Manufacturer/dp/B00E5NOXM4
If I have the Nexus at 100% battery and shut off the screen, it will be completely dead after 24-48 hours. Considering that this is standby and that my old old old iPad 1st Gen had a standby time of a couple WEEKS, I'm thinking that there is something wrong?
How long is the standby time supposed to be on the 2013 Nexus?
Is it possible that the case is actually somehow turning on the screen behind the cover and just leaving it on?
Assuming you are on stock 5.1.1, then the battery life is pretty poor....
Mine will only last 48 hours max on standby as it repeatedly wakes up, albeit with the screen off...
I have tried to disable anything I can to stop it waking up, but no good....
KitKat was far better in terms of staying asleep IMHO.
I actually have two N7's and have rooted the seocnd one and am running CleanRom and that is a LOT better at sleeping and so lasts a lot longer on standby.
Why would it be the case? It's not like the case is going to randomly turn it on and off... And if you need to test it; take it out of the case.
My N7 loses a few percent overnight at most... I've left it in my desk at work over the weekend by accident.. Off the charger at 9am Friday, looked at it 9amish Monday, it was at 83%. Nothing special, was stock L at the time.
More then likely you have software installed that is waking the tablet up or running in the background frequently causing the drain. I can unplug mine from the charger at 7am and not use it till 7pm and it will still be fully charged with that case. If I am super busy and don't use it for day or two it may go down to 98-95%. But if I leave Terraria open and put it to sleep by 7pm it may be down to 60-70% without even using it.
My OG ipad has stand-by measured in months. Too bad it's now completely useless. With the constant reboots and battery drains this N7 isn't far behind.

Battery life has declined since some version of lollipop. It's still pretty good but I've lost more than an hour of screen on time. It's impossible to pinpoint what app or apps cause the drainage because wakelock detector only shows facebook messenger as the sole big battery consumer but that's nothing new. In Android's own battery usage stats besides screen my main battery usage is "Android system" and "Android os" which use way too much CPU and cause abnormally much keep awake. I use Greenify and have almost every app except Google's own Greenified but lately I suspect apps bypass Greenify through Google Play services in some way.
But mostly I think it is under the hood stuff in Android and poor optimization from Google devs combined with Wi-Fi being always on. My old nexus 7 2012 which has "keep Wi-Fi on during sleep" set to never has incredible standby time. If not used I get 2 weeks.
Remember how much they praised project Volta last year's i/o, lollipop actually has shortened battery life. This year they called it doze. I honestly think it's just a charade to fool us to believe they put an effort in battery optimization.
^I guess it's just going to be different for everyone depending on a lot of variables.
You say you lost an hour with lollipop, I believe it but I can tell you that I've gained an hour compared to kitkat. So...
Standby time could definitely use some work though.
So I've noticed some weird battery behavior on my Pixel 2 XL and was wondering if anyone else has noticed this.
I normally like to ;et the battery drain down into 5% or so before plugging it in and letting it charge through to 100%. I started noticing that a full charge would take me nearly 2 hours fully charge. A couple of times last week, I had to step out and the phone was charged approximately 95%. I unplugged the charger and walked to my car (about 5-6 minutes to get to the car) and when I looked at my phone, charge had dropped to 88%. Over the next few days I noticed this kind of excessive drain immediately after unplugging the charger. Aside from this, I still achieve 24+ hrs of battery life on a single charge so I am not sure that it is a HUGE issue, but one I felt shouldn't be happening nonetheless. Last night the same happened - unplugged around 95% and i literally saw the battery indicator go to 93%, 91%, 88% and then stop at 87% in about a minute. I immediately called Google support, shared my screen, and after speaking with the person on the phone - i was told I should definitely RMA, which i did..so I have a replacement coming.
I don't use always on display or always listening and I am extremely good at clearing open apps before I put the screen to sleep. I have noticed this at home, on my wifi as i always need a charge later in the day when I'm home from work. Also, I use the OEM charging wire and brick.
Anyone else notice this ?
I have not noticed battery drain fast after unplugging at full charge level. I would say you probably should RMA the device. Also it is not good to let lithium-ion batteries go down to low levels a lot like that, it will degrade the battery faster. The less you let the battery go down to low levels, the more charge cycles you will have, which means long battery life over time.

I definitely did RMA, it was a painless process.
And I always thought that maximizing the charge of the phone (letting it get low, then charging up) would actually keep the battery healthier as it would reduce the # of times I charged it. Am i way off base with my logic for that?!
Going into my third week with my 2 XL and I haven't seen anything abnormal regarding battery drain.
I do practice the method of unplugging at 85% and plugging back in around 15% (per Accubattery's reco, and other reading done online)....
There's no proof that it helps as suggested, and while I realize that only allows me access to 70% of the battery's charge potential, I'm rarely, if ever, away from a plug for more than half a day.
This theory worked well in my 6P until it got the intermittent BLOD... My battery health was around 84% (via Accubattery) after 17 months of pretty heavy use.
Again, not sure it is solid fact or not, but you could always try it for a month and see if there is any noticeable difference in battery drain.
Thank you for that insight! I will absolutely do some research. You're battery health after 17 months is really impressive. I just switched from a Nexus 6p that was definitely showing signs of wear after 2 years of fairly standard use. I hadn't used accubattery, but I will download it on my new replacement and monitor results.
I will say though, that aside from that slight blip i noticed - the battery (andOS optimization i'm assuming) is amazing. I get through a day plus easily. So, anything I can do to keep that consistent or squeeze more time out of it is a no brainer.

Lithium-ion batteries work on charge cycles and are happier between 50-85% charge levels. You cannot really "overcharge" the battery because the phone will stop charging at 100% and just trickle charge to keep the battery at this level. But unplugging it after full charge defiantly wont hurt. If you keep the battery at higher levels I would't be surprised that you would get 1500+ charge cycl.es out of the phone before any real degradation which should easily get you years of good battery life. I find the battery life on the XL to be awesome and it lasts me throughout the day with still 40% battery life left and that is with pretty heavy usage.
Has anyone else noticed that 100% battery lasts much longer than any other percentage?
For example, last night I had my phone charging while I was watching TV and fell asleep. When I woke up a took my fully charged phone and went to bed while leaving it off the charger. I woke up five and a half hours later with the battery still at 100%. I then used it for 15 minutes of browsing before it finally dropped to 99%. However, if I had went to bed with less than 100% it would have drained probably 1-2% in the same amount of time with no usage at all. It almost seems like 100% is really only like 98% and it can actually be charged to more than 100%. After it drops to 99% the drain rate is pretty consistent.
I actually noticed this when I first got the phone almost a month ago and at first I thought there was a problem with the phone being stuck at 100% because it stayed there much longer than any other percent.
Anyone else see this? It doesn't really bother me since everything below 100% is very consistent. I'm just curious.
Same happens here. I listen to music (bluetooth to truck stereo) for about an hour everyday on the way to work. When I get there it still says 100% every day. Then after about an hour in my pocket doing nothing it magically says 96%. I have been suspecting that the on screen percentage is not registering the drop in power for a short while. But maybe I'm wrong.
I remember the Nexus 6p used to do that, haven't experienced it yet with my pixel though.

I have noticed that as well. Usually, my ~30 minute bus ride consists of my phone draining between 5% to 10%. But when I have the phone start from 100%, it's never drained beyond 5% by the end of it. Must have something to do with the fact that the phone charges slower when it reaches 80% or above (which they only claim to prolong battery health, not battery life). Eh, won't complain about it :fingers-crossed:
If I have had my Note 10+ on charge all night, as soon as I disconnect it from the charger the next morning the battery drops down to 98% within the first few minutes without me using it.
It seems to last ok the rest of the day as I have around 60% left after 4h sot. I know it's not a big deal but my Mate 20 Pro would sit on 100% for the first couple of hours. It's probably just psychological, but it feels like it lasts longer when it doesn't drop so quickly.
I guess my slight OCD isn't helping which is why I always turn off the battery % in the settings so I can't see what it is, but with the Note, even if you turn it off you still see it every time you pull down the notification panel.
The battery calibration is just a bit off. My recommendation would be to ignore it.
A factory reset should reset the battery statistics.
Battery seems pretty good so far.

That's Android 9. I'm guessing you haven't upgraded to Android 10 yet? Wonder how's the battery on that
My battery percentage is similar. By the time I get off the pot in the morning, it reads 98%, that's generally anywhere 2-15 minutes in my estimation.
Mine too, I consider it as normal, the rest of the batt lasts as expected
Same here. But rest of the day Usage and percentages are still pretty good.

to everybody with battery quick drop
this is normal because samsung implemented a new measure of battery security and not let the phone to mantain full charge for a long period of time ,
samsung staff tweeted this 3 months ago
