My battery seems to charge oddly fast at times and only last just about as long as it was plugged in for. Example being that this evening my phone was completely dead, I plugged it in and charged it and jumped to 35% in about 10 minutes... unplugged it and it lasted for about 10 minutes.
And then this just happened: I just unplugged my phone it was at 100%, I had no service(which is usual) so I restarted and my phone went down to 63% immediately upon boot. I use my phone average - heavy use (surfing the web and texting) but it lasts about 6 hours on a daily basis. Normal? Anyone else had these issues?
Thanks
Other info:
* It is rooted
* I had this issue for sometime now, did a hard reset last night and re-rooted immediately . Battery was great like the first 3 days now its 6-8 hours.

Seems like the OS is incorrectly gauging your battery levels. Since you're rooted, you could try getting clockwork recovery on there and wiping battery stats.
Though if you're getting 6-8 hours on avg-heavy use (as you put it), then there might not be a problem with the phone. I would say I use the phone moderately (approx 3 hrs screen-on time) and I can get approx 12 hrs battery. Most of the background stuff on my phone is push with a few apps set to auto-update every few hours.
Try and see how well it idles from a full charge (unplug it before you go to bed).

with the phone left switched on i put it on charge last night at around 10.30pm
got up at 5.15 this morning to see the green light on
when i went in to battery info to check it said the following
full charged at 00.50monday 06 july
stand by time 4 hrs 15 mins
device usage 13 mins
how can this be
i was in bed so didnt use the device
and why is it saying fully charged at 00.50
with the charger still in and power switched on does this mean it does not take any charge once the light is green
hoping this may solve my battery problem as im on my 2nd TP2 and the battery lasted less than 18 hrs use yeaterday with about 15 mins of use
thanks for any help

k first of all, it's not a good idea to charge it overnight like that. take it from me, when I first got my Tilt (which was my first phone that used a Li-ion battery) I would charge it overnight all the time so that I would have 100% in the morning. but I noticed that the overall battery life slowly began to decrease the more I charged it till the status light was green. I ended up going the warranty path and had a brand new one sent to me, and ever since then I've monitored my charging, making sure that it didn't charge to the full 100%, and it's been fine.
It could also have been that specific battery. I always charge my phone overnight, and nothing goes wrong.
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
Hello, a couple of months ago my battery started dying on me so I went to Samsung to get a replacement (my tablet is still within warranty). Despite the fact that my Knox counter is triggered they've changed my battery as well as my tablet's motherboard (don't know why). In the first few weeks I would get quite good battery 7-8 hours of Screen on Time, so far so good.
In the last month or so -though- I'm starting getting quite worse results. The battery leak while sleeping is 2% every 8 hours, so I'm great there too (amplify + greenify work miracles), so the only thing that I can think is that the battery has started dying again (already?). I've let my tablet reach 0% and shut down on its own. Then I booted into recovery and let my tablet on with full brightness for another hour until it was finally off. That's *one hour on* with full brightness!
It seems obvious to me that that's a calibration issue. I deep cycled my battery (twice!), but the results persist (battery is 0% after 5.30 hours of SoT, an additional hour of full brightness is needed until my battery is really depleted). I've made the calculations and found out that if I could actually use that extra hour of full brightness, I would still get 7-8 hours of SoT.
What happened? Why is my battery suddenly got itself "decalibrated" and why does deep cycling (or deleting the battery starts) never works? I think that I should get my tablet back to Samsung again (it's still within warranty), but I would prefer not to as it'll take another 2-3 weeks (again!) to fix it and I'd much prefer to have my tablet in the meantime. So do you have any quick and dirty method to get my 2 hours back?
BTW I know that 2 hours less of screen time , sounds little. But it's exactly the amount of time that deems whether I should charge my battery twice or once every day (yeah I use my tablet *that* much, as it also doubles as my laptop on the go)
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.
