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:

This morning after I got ready I took my phone off the charger (it had been charging all night and was at 100%) and walked upstairs. About 10 minutes later I turned on the phone and it was at 67% and going down. I had flashed a new rom yesterday and as quick as I could I did during the drain I did a NAND restore. Could this have been actual battery drain or is there something wrong with my phone/stats. Could my phone have stopped charging at 50% and then just said it was 100%? What should I do? Is there anyway to avoid this from happening again?! I cant go to work with a battery at 50%! lol
-.- Searching is your friend.
The Evo has never trickle charged properly. Trickle charging is when you hit 100% battery while charging and the phone will continue to keep the battery charging and maintain this 100%. So 100% > 99% > 100%.
The problem is the Evo doesn't do this. Once it hits 100%, it switches to battery. It will run off the battery till it hits about 90% and then charge again. Some even say it will NEVER charge again after it hits 100%. So when you unplug it in the morning, you end up dropping extremely fast from 100% to 90%.
There are kernels in the development section that fix this issue but there are people who say it will break your phone or burn your battery out faster over time. When trickle charging, your phone will get hot as its constantly draining and charging. That can lead to a burned out battery as time goes on or a damaged phone. I personally have three batteries. I still tried to use this and noticed a drastic improvement but my phone was also pretty warm when I picked it up in the morning. Its up to you.
Also you might want to see if you have your 4G radio on. That is probably the only thing I can think of that would drain it that fast. Either that or your GPS is on and theres an app running thats using the GPS receiver.
i'd say a 30% drain in 10 minutes is unnatural. it wouldnt be myns rls4 that you flashed, would it? this is experianced by some as a "first day side effect". just fully drain and fully charge the battery a few times and you will be fine.
It could be that it just needs a couple drains and I don't want to quickly point the finger at an app that you are using. A lot of times if I actually charge my phone it will be on 92% when I wake up. 67% is a stretch unless that was 10 minutes of a game or YouTube..but still. Drain the battery a few times and see what happens.
i was thinking maybe its some kind of battery stats problem? Could that have caused it?
Hey Guys,
i got my ZL 3 or 4 weeks ago, and can say it´s absolutly awesome, but since ca. 2 weeks, i have a problem with my battery. The problem begun, as i found my battery completely discharged, so i put it on the charger. But it didn´t charge the whole night. In the next morning it startet to charge, i waited till 100% an took it off the charger. Over the day, i watched the battery drain, and it was more than normal, the battery went empty, after a 5 or 6 hours with 95% standby time. At home i charged the phone again up to 100%, ab pluged it off, the next morning, the battery had lost not a single percent off its charge. So i went to work, with the phone in my pocket. A little later the phone got really hot, i pulled it out and, found the battery with only ca. 55%, so i turned off the phone. 45 minutes later, i turned it on again, and the battery had only 27% left. And so it goes on the next days, with more or less battery drain, some days the battery holds 10 hours perfectly, and at some other days it only holds 4 hours and less. And now the charging procedure have problem too, when i charge the phone via USB, it charges unbelieveble slow, and even discharges sometims , but when i charge it with the power adapter, it charges unbelieveble fast, you can watch the percentage rise in minutes. I tried the STAMINA modus but, it didn´t help at all, and the screen is on the lowest brightness.
And i have too say, i don´t have any apps activ, and 3G is only on for a few seconds sometimes.
The phone isn´t rooted, or everything else, it´s completyly stock.
I hope someone experienced any similiar problem, and have a solution for me, because it´s an awesome phone and i didn´t want to miss it.
(Sorry for my not so good english)
Yours faithfully

running the 2/16 release of CM11, battery meter is acting funky, but battery life seems normal. I have no idea if it started with CM11 install or just out of the blue. couple week ago after 13 hours of running on battery I noticed the meter still said 100%, then about an hour later it said 52%, and 30 seconds later 12%, battery low warning, and 15 seconds later it did a clean power off. plugged in, powered off charging said 9%, and was 52% again in about 30 seconds.
battery still lasts all day, but I have no idea how drained it is until about an hour before it's dead. it also won't actually charge unless the meter says it's below 100%, but plugged in it also doesn't drain it more. using an app to monitor the battery, it rarely shows above 3850mv, and will hover there all day long going up and down 300mV or so, but then late in the day it'll break from 100% around 3700mv and the % starts dropping.
so, what's going on here?
so, left on charger overnight (as I do every night), status app said USB power on but discharging. came to work, plugged it in (as I sometimes do), battery said 100%, again USB power and discharging.
unplugged to go to lunch, 54%. sat down to eat, 65%. few minutes later, 70%. from there it started dropping at a normal rate. used it heavily all through lunch, only went to 58%, and seems to be charging normally now as well. I'm so confused... it's been wrong for at least 2 weeks strait through multiple charges and reboots.
What about 'calibrating' the battery?
if it does it again I'll to find time to drain it and then fully charge it powered off, but with an inaccurate reading of what the charge is it was very difficult to fit that into my schedule.
it seems to have calibrated itself now, as it's been fine all weekend.
so the questions is now: what caused it, and why did it fix itself some weeks later? I certainly didn't do anything anywhere near a calibration cycle.
So I updated my phone tonight and after it used 30% in an hour or so. All I was doing was using FB on it. Prior I played PAD for 15 minutes and it hardly used 5%. I've wiped cache, cleared app cache, and now I'm working on a full discharge from 100%. The battery is brand new and it was getting better life prior to the upgrade. So much for 3x better battery I guess?
After clearing caches I left it idle ofer night. It used 13% for 20 minutes of screen time. and then it used 3% idle over the 5 hours I slept. Still seems a bit high on usage for screen time but idle is great.
So I discharged it completely and now its losing power fast again. The battery was 100% unplugged it and turned it on and its 97%. So I turned it back off and checked it and its also showing 97%. Charge it back to 100%, turn it on, its on 100% but loses 1% in a second. Plugged it in while onand it took like 3 minutes to charge that last 1%/ No idea why. The battery is brand new and got 2 or 3 days on idle before, now it reports 20 hours. what happened to that 3x better battery? What else can I do to sync the battery properly? I also noticed 100% is not 100% until the phone tells me battery is charged.
Again this battery is brand new and my life with 5.1.1 was pretty good.
I've been having poor battery calibrations in EPH7, though my battery is still what came with the phone.
There are days I can get to about 5? left before the phone dies, and there are days it dies at 15?..
Already tried charging all the way till full while the phone was off, still the same. It's random, but I just generally expect the phone to turn off as I come close to 15?.

That sounds like a bad battery. I can get my phone to drain down to 0% before it dies, but the battery usage can be erratic.
After some testingm the first 5% (95-100%) does down fast but after that it can go a pretty good while. Not sure why. I left the screen on with max brightness, turned on NFC/wifi/bluetooth and just left tons of apps running and it took 4-5 hours to get the battery down to 20%. the life is in fact great just not properly synced. No root makes it more of a pain to calibrate.
So I charged the battery offline and it got to 100%. I switched it on and it shows 97%. What the hell has marshmallow done to my note?
last post. If I charge the phone formt he OS it reaches 100% seemingly properly and doesn't discharge quickly. Not sure what marshmallow screwed up.
I had the same issue with my battery draining quickly after the upgrade. I backed up all of my data and then performed a master rest of the phone and then went into recovery and cleared cache as well. Once it booted back up I reloaded all of my apps and reconfigured all my accounts and my battery acts normal once again. It was a pain in the ass to do all of that but it did work for me so hopefully it works for you too.
Phone was at 98% battery. Did a reboot as I do every morning, and when it started up again it showed 91% battery. I know reboots don't take 7% battery, so what gives?
My Pixel 2 XL has been having some battery reporting issues, I noticed that when I took my phone off the charger it would lose 15% very quickly then stabilize. Rebooting would also cause a drop in indicated battery %. That's my guess. Investigating to see if it can be fixed by doing a full charge/discharge cycle.

I've also been seeing this issue! I will also be letting it do a full cycle today to see if it helps since it only started a few days ago.
My battery seems to be okay but my charge port when I place the cable in it doesn't feel like it fits snugly it almost has a slight wobble to it. Have you guys been noticing that as well?
I've actually been experiencing this as well for a week, I called up Verizon and they shipped me a new phone. So far no charge issue anymore on this one.
I have experienced this too
Tested this again this morning. Had the phone charging overnight.
Unplugged it, it showed 100% battery.
Immediately rebooted, and it dropped to 96%.
With a lot of phones, battery stats reset on reboot. Also- the percentage isn't a perfect science. Just let the phone do its thing. Run the battery down and recharge it. No need to reboot the thing every day.
The battery has been great for me. I use my phone extensively throughout the day, maybe 3-5 hours on time, I always make a day of use without needing to plug in. I had a light use day yesterday, and had 30% left @ 11pm, after pulling off charge the night before @ 11:30pm.
Pleased to announce that (in my case at least) doing a full cycle reset the fuel gauge and it is now working properly. I've never seen a device come with a miscalibrated fuel gauge from the factory, so that was odd. I usually keep my li-ion powered devices between 80% and 30% SoC(state of charge) to reduce cell degradation so we'll see if the fuel gauge becomes uncalibrated over time (which would be somewhat unusual) or if this was simply a software fluke.
Yea I have noticed that in my case, my phone says 100% on the charger so I will restart the phone while still plugged up and once it's booted back up it says 98% so it lost 2% while hooked up to the charger lol. Doesn't seem to affect the battery life. I'm still able to get 5 hrs of screen on time but I will try to kill it completely and charge fully today and see if it fixes it.
This morning I didn't do the restart and didn't use the phone or even turn my screen on and within fifteen minutes I turned it on to 98 % remaining.
