So my maxx will drain to 1% battery in about 3 days with 3 hours screen time. The thing is once I hit 1% it can stay on 1% and not shut off for hours. Right now its been on 1% for about 7 hours, I have a youtube video going just to see how much longer it will go. Its been playing a youtube video now for about 20 min on 1%.
I just got this phone last week, is this because the system hasn't fully calibrated the battery? Or is the battery defective in some way? Its kind of annoying because you think you are out of battery but it keeps going so I don't really know how much battery I have.
Definitely not normal. I'd do a factory reset to eliminate a software issue and if the issue persists seems like it must be a hardware issue, exchange it
These sound like calibration issues. Can you fully charge your battery and then leave in on the charger for awhile -- like an hour or more? That should calibrate it correctly.
I have never nor will ever let my battery get that low. These batteries don't like to be drained and then fully charged it's not healthy for the battery. I don't let my battery go below 30 to 40 percent if I can help it. Most of the time I let it get to about 50 percent then I charge it.

not to be rude but where is you information or evidence backing your statement? this goes against everything i know and i certainly always allow my battery to fully die then i fully charge it over night while it is off, i believe charging at 40 percent fools the battery into thinking that is the end of the battery's daily life span and therefore dying prematurely due to it believing that 40 percent is the end.
I do not have any real evidence except i've gotten exceptional battery life with my Ultra after allowing a full cycle (draining all the way and then fully charging while powered down)...i have gotten just under 32 hours with 4 hours and some odd minutes screen on with about an hour of voice calls and random other usage such as tapatalk browsing, internet, texting and maybe some email or youtube....i occasionally play some games like the new CoD Strike Force

The best source is battery university. Here are a few good links. In the first, look at the third column (Li-ion), as that's the battery pack in the Maxx/Ultra/Mini
http://batteryuniversity.com/learn/article/how_to_charge_when_to_charge_table
http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries
From the second link (emphasis mine):
Similar to a mechanical device that wears out faster with heavy use, so also does the depth of discharge (DoD) determine the cycle count. The shorter the discharge (low DoD), the longer the battery will last. If at all possible, avoid full discharges and charge the battery more often between uses. Partial discharge on Li-ion is fine; there is no memory and the battery does not need periodic full discharge cycles to prolong life, other than to calibrate the fuel gauge on a smart battery once in a while.

So happy I seldom charge up to 100% and leave it sit. I also never let it get super low.

Coming from a Gnex, I have a charger within 3 feet of me everywhere I go. I'm trying to break myself of the habit of plugging it in but mine still gets a charge at some point during the day, if only in the car. It has always been my practice to let my phones run down almost to dead maybe once every couple of months. I feel like it keeps the phone's battery meter calibrated although I have nothing to base this on.

Just got a new Z3 D6616. This is the battery life projection I'm getting. I bought this phone because I heard great things about it's battery life. Also, when I saw a YouTube review, the guy's phone had a battery life projection of several days. Is something faulty with this specific handset? Am I doing something terribly wrong? Please advise.
PS. I'm at about 30-40% screen brightness with the adaptive setting on.

You should actually use the phone from 100% doing your daily stuff till about 1% and take screen of your on screen time. On screen time is what matter. They claimed to have at least 8 hours SoT with normal usage but the max I can get is only 4.5 or 5 hours.
I did a lot of reading before buying the phone. Heard about the "memory" screen or something that helps towards battery life. Several users claimed 10 hours SOT. Could it be the newer firmware that might have reduced it? I'll post the YouTube videos I saw shortly.
I use brightness at about 1/3 and have location and autosync on. I get about 8-9 Hrs SOT in a 36Hrs period.
At first even I got 4-6 Hrs SOT until it calibrated over a few charge/discharge cycles.
It takes a few cycles for the battery to calibrate, if you want to do that faster do the following:
1. Drain to 0-1% with normal use
2. Do a full charge till 100%
3. Do another full discharge (Dont charge in between)
4. Do another full charge till 100%
5. Now just use it how you want.
Thanks! Guess I'll have to report back report back after a couple cycles.
I have the same problem, I have enable the stamina mode, have the brightness at half and auto,and the battery won't last for one day,as an example today when I get up after I unplug the device it go from 100% to 99% right away and now after 10 hours without game,photos just Internet reading over WiFi the battery is at 31%. It doesn't seem normal, what should I do?must go to service?
I'm at 59% and my phone predicts 1 day remaining.
D6616 as well
I do suspect an app draining my battery though...

The battery life I'm experiencing is worse than the "forecast", which is essentially what worries me. Regardless, I've no right to whine unless I've cycled the battery completely at least once since it is after all a brand spanking new phone.

I doubt I'd get the 24 hours from now with my current use either. As long as it lasts me throughout the day I'm fine.
I can generally go the entire weekend without charging my phone though.
Ive gone through 3 Z4s (Cosmetic defects/lightbleed) on my 4th Z4, all of the were bad until they were calibrated within a few days.

I fully discharged and recharged my phone. Now I got 18 hours usage, including 7 hours SOT with the screen on max brightness for half an hour. It's getting much better now, certainly a huge improvement over my previous phone!
Sent from the inner sanctum of my mind.
That's more like it, it should get a little better.
Please have a look towards the end... My phone's been awake when I was asleep. Is there an issue with this phone deep sleeping? While I get a good SOT, the idle drain is too high! Please advise on how I could investigate if a particular app is doing this. I used to use "wakelock detector" but that no longer works without root.
EDIT: Stamina Mode always on.

I have the same problem too... Whenever I leave the phone idle, even with the stamina mode on, it still uses the battery as if I was using it.
On my G3, when I fully charge the phone, it would stay at 100% for a VERY long time before dropping down to 99%. The most I've gotten out of the 1% before was about 25 minutes of SoT.
On my S6, once the phone is fully charged, it seems to drop to 99% very quickly, within just a couple minutes of using the device.
What causes this difference between the two models and does your S6 act the same way as mine?
So far my GF and I notice the battery drops quickly also.

That's pretty damn good if it do so. That's 10 hour SOT.
I can barely get 4 hours SOT.
Battery life is good for me.
19hrs since last charge, 52% power remaining. Screen on time of 1h 15min.

Genetic is inline to get around 2-3hrs SOT with almost 40hrs Standby thats not too bad actually
But on screen time ia surely more important

Sure SOT is important but it depends on your standby too. Example 6hrs SOT with 8hrs Standby is kinda expected and normal. If you can get 6hrs SOT with 24hrs Standby the that is mightly impressive.
True but 19 hrs standby and 1 30 on screen is awful. That means you picked up the phone and drained it half way in an hour and a bit

Im not sure you get how it works bud.
That 1.5hrs SOT was not achieved in one continous sitting.
If you read my previous post i explained that you can get 6hrs SOT with the S6 easy but your standby will be short say around 8hrs. If you watch videos no stop on the S6 you could probably get 7-8hrs SOT before the battery is flat. This is normal for the S6.
Basically: Long SOT = shorter standby
Long standby = shorter SOT
The Holy Grail is Long Standby + Long SOT
EDIT: Im only referring to the S6 in my asaumption. There are flagships out that can get long standby and long SOT already out there namely Note4 and Mate7.
I have pretty terrible standby time though. An all nighter drained 10% but if i use the phone continuously i could get 4hrs of sot lol
Brightness was on auto

I get about a day standby with between 4-5 SOT.
Overnight drain is around 3-4%, I normally sleep around 7hrs a night.
I'm using XtreStoLite seriously debloated ROM, Ktoonsez 920F Kernel.
Also using App Ops and Disable Service to kill Google Play Services wakelocks.
Hope this helps you get better battery life bud.
Playing music through streaming music app Simfy, doesn't require the screen to stay on.
SOT isn't the only way to gauge a battery's performance.
Haha you guys took this thread pretty off-topic. My question was more related to the actual way your battery drains vs battery life.

Hmm i wouldnt want to root and unlock yet. Im gonna give it at least a month or two because the rattling home button is quite a concern to me. Even though its not really that bad
Man I must be lucky cause battery life for me looks REALLY good, especially considering the small capacity and the 2k display. Last night I fell asleep in front of the TV with my phone at 20%, woke up this morning and it was still at 20%. It's sipping battery nicely. I'm happy!

I noticed the same thing with my S6 the first night I got it. It came with 50% battery and after an update and me playing around with it a bit I went off to bed at about 23%. The next morning I woke up and it was at 22%. I consider that to be exceptional considering nothing was disabled and it wasn't even on its first charge.
Unfortunately I haven't been able to fully set up my S6 due to exams so it's been sitting on my desk looking pretty. I'm still using my S5 for the time being and plan to fully switch over to the S6 in the next few days!

Android System and OS together are eating nearly 50% of my battery.
Same here. System and OS eating my battery.
20 hours with 4 hours SOT. I'm not complaining. Much better than the s6!
First charge with massive wakelock issues...
Completely impressed with battery life. Pretty solid so far.
Not sure how everyone is getting all these legit battery stats. I'm only getting about 4-4.5 hours screen on time.
I'm at 15% with 3 hour 45 minutes screen on. No so impressive. I charged my phone before I went to bed and lost 16% with it just sitting, while I sleep. So much for doze.
Having the same issues. Trying to figure out what I'm doing wrong that everyone else is getting so much better results.
Anyone else care to comment? I'm getting pretty mediocre battery life. I expected ALOT BETTER. I'm averaging 4 hours screen on time. Android system is eating 37% right now.

Got the phone 2 days ago, it's a bit early but I'm not getting crazy battery life: I listen to music a lot (5-6h/a day - Deezer or Poweramp) and get 5-6%/hour drain, a bit less (maybe 2%) while idle. Coming from a Nexus 6P this isn't great...

Anyone else have heat issues, my phone got crazy hot and I was just using fliboard no gaming or video watching.
Give it a week or so before complaining
Mine took 5 days to settle
Afterwards a constant 6.5 hr sot sometimes 8
anybody having battery issues,cycle the battery completely and it should improve. when i got my S7 and My S6 also battery was garbage. I did 2 full cycles and man im getting crazy battery after..
anyone not knowing exactly what I mean by cycle heres what I did
use the phone til it dies completely DO NOT TURN BACK ON
plug and charge til its fully charged turn back on use it again til it dies
and AGAIN DO NOT TURN IT ON just plug and charge fully before turning back on.
that was 2 full cycles did wonders for me hope it does that same for ya'll having bad battery good luck:good:
I've done two cycles. I average about 23 to 24 hours between charges. With 3 and a half hours screen time.

After a week here's my new stats. Much much much better
Wondering how is your battery life, I'm 5:30 hours for 54% of battery(75% - 21%)
I max charge it to 75% and usually I don't drain it less than 25% - To achieve the best battery life long term, so I won't need replacement anytime soon. Also I don't fast charge, usually 1A charging or similar(e.g. Wireless charging 7.5W)
Obviously I use underclocking to the point I don't fee any difference in daily usage
Share your thoughts, for 0-100% I bet I can do more than 7:30 SOT

Lol mate you're more like 5:30 min after 75-25 twice.
Such a bad battery life usually happens after using mokee as they change low lever instructions in the processor.
What happens is that the processor microcode is changed such that instead of power being managed by the relative motion of conductors and fluxes, it’s actually now managed by the modial interaction of adreno-reluctance and capacitive directance of the cores. You can not change that any more as it was a change on hardware level microconductions that can not be reverted.

50%(75-25% usage) of battery gives me 5:30 SOT hours and it's bad?
You troll right? this is only achieved with underclocking, at 100% you should expect more than 7:30 and maybe 8 hours! what about you?
P.S. Give me your SOT 75-25% and if it's more than 5:30 SOT I'll send you my phone for free - Bet you can't even do 6 hours SOT with full battery
just look at the screenshot you provided yourself, the battery graph clearly shows you charged your phone after you hit 25% the first time to 75% and let it run down to 21% again. battery (and sot) stats won't reset until you charge over 90%, so your reading of 5.5 hours of sot is actually 2 instances of your habitual 75-25% drain. in reality you are only getting about half that for 50% use (~2h 45min sot), which I'd say isn't too bad, but maybe you should do a full 100% to 0% use once and see how the battery fares for a more accurate reading. honestly I would say you would still get around 5.5-6 hours sot from that, and that unless you do some serious tweaking to both your phone and usage patterns you wouldn't be able to hit 7 hours sot, but I would be willing to see evidence that proves me otherwise.

Battery Charge Limit - Resets your stats but also limits the charging
I know you are clueless but talking without knowing is bad - 5.5 is for 50% battery due to high underclocking I've got
With 100% I can get over 8-10 hours - High end CPU cores are not more than 1.5Ghz, gpu at power saving but also lowest possible freq for min/max - You are talking crap but ok I won't feed you, I stop feeding trolls the moment I get they troll
sorry but you are the one talking crap, please see attached picture, which is a crop of your battery graph. i personally also use the battery charge limit app, and i know how the reset battery stats option in the app works, which will clear the battery graph as well. if you really did clear battery stats you wouldn't be able to see this upward curve.
how about this, you fully charge your phone and use it normally until you hit your claimed 8-10h sot. honestly i think i can match your sot, but without this underclocking you highly praise.
You're either braindamaged or a troll. You charged your phone and it didn't reset stats so it combined both usages. Did you pass 6th grade maths? Anyways SoT is subjective and you're just being extra petty about this

Removed lots of bloatware using adbFastboot tool and connected mostly on wifi. Without wifi with medium usage, I can get around 6 hours SOT within 2 days of use.
aex + canting.
I've had mine for 18 months and am still very pleased on the charge. I can typically get 12 - 14 hours fine, and that does me for most uses. I've seen it go longer when I've used it less (for example right now 20 hours without charge - 6% left, although that would include about 7 hours of sleep so no use in that time).
No modifications on my part.
