welll, after the lollipop update, my battery went strong lol, in kitkat, normal browsing/youtube at 1/8 brightness will drain the bat like 50% in 2 hours. playing COC drains as much as 1% a minute and the batt percentage jumps, the device will get so hot to a point that it will induce a warning and will close all apps,. it will deplete the batt so fast that it shuts off. showing 1%, powering it on again will show at least 30-40% juice left. in lollipop, since like the batt meter is now calibrated and playing COC will no longer make it hot.
Kitkat last me half a day with casual browse/sms/calls
lollipop lasts me a whole day and i still have a bit juice left
2 hours is a bit fast, was it a full charge, the 8,4" has an 4900mah battery and the charge puts about 1500ma into the battery in one hour, using supplied charger and cable, other brands can cause your tablet to charge much slower.
try the free version of GSam Battery monitor, it`s one of the best to keep an eye on your battery.

Hi all,
I was just wondering what everyone's else's battery usage looks like, because ever since I got the phone I've been having very poor battery time (it only lasts 7 hours with barely any heavy usage; wifi on only when needed). I want to know of it's something I'm doing wrong or if my battery is the problem.
I've disabled some annoying apps from running constantly (e.g. Photobucket) and am running Launcher pro with some widgets (manual refresh only). I don't know what else I can do to save my battery... screen brightness is low as well.
So, what does your Battery usage thingy look like and am I doing something wrong?
Thanks!
P.S. Is the 'Android' supposed to take up that much battery?

I get fairly good battery use throughout the day. I'd say with moderate to heavy use I get about 15-20 hours before the phone is dead. Right now after six hours unplugged it's at 76%.
Board won't let me post outside links yet

Definitely look for juice defender, it saves battery life by turning off your data plan when the phone is on idle (screen is locked) and it automatically turns on when you unlock your phone. I had the exact same issue you're having now and only originally getting on avg 8 to 9 hours on my phone while I was only at school for 6 hours.
After a day of installing juice defender I can honestly say I can comfortably have my phone on for 10 to 12 hours of use with mild usage (1 hour of pandora, 1 to 2 hours of angry birds, and some web surfing) and the battery'll still be at roughly 50some odd %. Trust me you can definitely live wihout having your internet one when your phones in your pocket.. just my preference.

As the graph shows... Not connected to the charger yet it increases 5% in battery life, went from 29 to 34...

Same
Mine does the same actually. Everytime I look at it when its below 50% life it always has a part of the graph as it charged a little bit. seems wierd
The battery usage and percentage in the notification panel is more of a guess of where your battery really is based on usage. A lot of usage will cause it to guess your battery is at a certain level, and then less usage will lead it to believe your battery is at a higher level.
It also has to do with the charge going to the battery, but that's a bit more involved.

This is normal behavior for a battery, i've had this with all my android phones (HTC Magic/Galaxy S/Galaxy Nexus).
I have that too. But I believe Tesla hasn't died and is currently working with Google or Samsung on some sort.
Poorly calibrated battery or a big change in ambient temperatures?
For example here in Finland, it can be like -20'C outside during wintertime and the battery seems to take a hit when using the phone outside and after coming inside to +20'C (or more) it could suddenly (when warming up) load the battery magically
Mine does the same and I love it!
this is normal for this type of battery fuel gauge because it's based soley on voltage. and you pressed the phone hard during that steep slope, then went idle, and voltage tends to rise and bounce back up when in a relaxed state. when this bounce is large enough it moves the SoC as well. it's all normal.
How many of you did receive a dead battery on arrival? Some people in sweden did and they claim to have terrible batterylife according the themself. This units dosen't seem to survive a day with easy use. Could it be a connection here with a dead/over-discharged battery and the terrible batterylife that some experience?
How many of you did receive a dead battery on arrival and does it perform worse than avarage?

Uhm I got a normal one but a dead battery could be a bad sign considering this kind of battery technology doesn't like being on low % of battery. If your battery had 0 % from the start it could really damage it.
There could be a link between an empty battery and bad battery performance.
(Just my 2 cents)
My phone didn't arrive dead, but they turned it in for me in the shop and it died on me on the way home. Plugged it in to power and it took ages before it displayed a flashing orange light, then another good 15 mins before I got a solid orange light and it was charging to the point where I could turn it on.
That said, here are my stats today.

I would expect to get over 4 hours screen on time, which seems ok to me, considering we should get further improvement with updates.

Hey guys,
I've really liked this phone - until a few weeks ago.
I had the fated sudden decline in battery life. BetterBatteryStats has been on my phone for a while, so I opened it up and checked what usually kills battery on Android: the wakelocks.
It seemed totally normal!
Then, I checked processes. (These are today's stats, still just as bad)

system_server?
I noticed my phone was getting warmer whenever I was actively using it right under the camera, I guess which is where the SoC is. It's also been getting noticeably laggier.
Also today, under the battery usage in the settings:
Android OS and Android System are using twice as much battery as the screen.
This is pissing me the hell off. My phone drains perfectly acceptable battery when it's asleep, but take it out to use it and suddenly it's draining over 20% an hour. The extremely vague and obscure nature of the process doesn't help either. What does system_server even do?
I'm running Tweaked, and I've been alternating between ColonelX and Lean with no difference in battery.
I've also dirty flashed (really don't want to factory reset) to the NF4 Tweaked 3.5 beta. Only difference here is less lag.
As for bootloader, radio, and all that stuff, it's NF4 as well.
Nearly all Samsung bloatware is frozen in Titanium Backup, and all other troublesome apps have been greenified.
Attached is a log from BetterBatteryStats.
Thanks in advance for your help!
(I'm typing this on my phone, and battery had drained over 10% since I started writing this post.)
I had exactly the same issue since I upgraded my note 3 to Lollipop. It was fine when the phone was in sleep. But when using it, it drained the battery super fast...
system_server consumed lots of CPU resource at most time.
Hi I am wondering if this is normal when we charge with a Fast Charger. I downloaded Gsam app and shows about 110-111F when it's charging, is that a safe level/normal or is that TOO hot and can cause battery damage?
after it goes to 75% or 80% it goes down to 96'F, it only gets hot below 75% for example 5% to 75%

My M9 maxes out battery temp at 45°C (113°F) then charge current is reduced until temp drops.
Generally higher temperatures are detrimental to battery life (above 40°C / 104°F) however all fast charging will cause excess heat and temp to some extent.
If your concerned then use fast charge when necessary and use normal slower battery friendly charge overnight when possible

I have similar concerns and would like to post about them here instead of creating a new thread. I upgraded my Dev Edition M9 to 5.1 earlier this week and I bought a fast charger yesterday. The phone temp increases to ~45 C (113 F) after charging about 20%. How do I fix the heating issue? I never tried a fast charger before the upgrade and don't know if the heating issue was present. Please help me out.
Are you guys on the most recent firmware? My phone does not heat up at all on fast charging.
I have the latest FW and I'm not experiencing overheating with fast charge either
I've noticed my phone getting so hot sometimes when fast charging that the charging led starts flashing red.
I actually have a blister from picking it up...which HTC assures me is rare, but within acceptable limits. So, I guess it's normal
