So I've had my phone for about 2 weeks now. It has been working flawlessly to this point. Battery life had been outstanding. This morning, however, I unplugged my fully charged phone and began playing with it for 20 minutes. It immediately went from 100% charge to 5%. I plugged it back in and it went to 100% when I checked back on it 30 min later. I thought that was weird but whatever. I then unplugged the phone and it immediately went to 77% inside of 10 minutes.
Needless to say I'm a little distressed. I've tried restarting my phone and turning it off for a while but it seems like he issue is still persisting. Has anyone else had this issue? Any solutions?

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
Tim
So i got the Battery last week. and did the initial 12 hour charge and then some. and battery worked great (lasted 3 days). then i got it down to 1% and then charged it to about 60 before i unplugged it. since then every night that i've put it to charge it charges normally for the first little bit and then has spiked where it goes to 75% then up to 100% then back down. It displays it as 100% but when i unplug it, it goes back down to 75%.
at this point the battery was plugged in for more than 24 hours and its still at 75%. when it is unplugged the battery performance is nowhere near what it was in the beginning or even remotely close.
anyone else had similar problems or am i doing something wrong ?
ps. i did battery reset.
ROM: CM 10.2.2 Nightlies
So one day my phone wouldn't wake from the lock screen so i restarted it and battery went down to 4% from 47%. I plugged it in to the charger and nothing. I tried different chargers and still nothing - no lights, nothing this went on for almost a week. I left it on the charger for couple hours on September 1st and then the red charging light came on and i turned on the phone and voila! it worked. I decided i wouldn't let my battery go so low again. The next day i was using my phone and it shut off at 20%. i went to charge it and nothing! this began to piss me off. I left it on the charger and a few minutes later it began to charge. Today September 3rd, i was using my phone and the battery was on 37%, jumped to 27%, jumped to 17% then 0% and then shut off. I plugged it up and nothing! This phone is irritating me. Sometimes it charges normally and other times it takes forever to start to charge. i don't know what the problem is. can someone help me please? @timmaaa any help?
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.
