When you guys unplug your gnex from the wall... (gsm)

Does the battery go to 99% for you guys instantly? seems like mine does, as soon as i unplug it goes to 99%, just wondering if its normal or just my phone, because on my galaxy s II i would get like 30 minutes of no drain, like it would stay at 100 for a while, while this phone is like as soon as i unplug the battery is already down to 99.

Calibrate it
Mine stays on 100% for a good half an hour or so too

what is the easiest way to calibrate it? any links.. my GNEX will go 99% instantly too but overall battery drain is awesome

my battery life is TERRIBLE on this thing, it drains like crazy.. i want to calibrate it super badly but im not rooted, so i cant delete batt stats.bin , i even let it drain last night completely charged it again while it was off..still same terrible battery life. its a shame because i really really love this phone.

I'm sorry but that sounds like badly calibrated battery. Lithium-ion Batteries are -never- 100% except for a very brief moment.
It is natural that your phone displays 97%-99% when unplugged (or even when still plugged in). Batteries protect themselves like this, because these batteries cannot be charged while they are full, they will stop charging the very moment you hit 100%.

Generally you don't want your battery to be above 90% for a extended amount of time, that much voltage/capacity speeds up the degradation of the cells. So actually you should be happy, because your battery will have a longer life.

He's technically correct. LiIon batteries are happiest around 60-70% charge level. However given that your actively using a cell phone battery and your not storing it at high charge its OK.
If you really want to learn more about Lithium tech I can link you to a forum where people are VERY serious about this stuff and use them for high powered lights.

This is a known design "feature."

Is this normal battery life for the first day of having the nexus?

I just got my nexus today and was wondering if this was good battery life for the first days use and when it will start getting better?

Thats a drastic drop! Id say about normal as well. Did you have a lot of apps that were re downloading from the time you first activated it. After a few days to a week when your done looking at your phone every 5 secs you'll start to see battery improvement haha.

Tonight will be my 3rd time charging it. WIll it get a lot better tomorrow?

ProTip: Put the phone down every once in a while and enjoy life.

That's normal if ur 4g on

It can take 4-5 charge cycles for the battery to really get worked in.
Also, check out the juice defender plus app. Doubled my battery life.

Lithium Ion cells do not get better in any way after a few charges.
In fact the capacity goes down a wee tiny little bit with each and every charge, so your first charge was the "best" one.
Stop playing around with the thing for 5 hours non stop and you will get decent runtime.

Best thing to do with a new device is to charge it up fully as soon as you can. Then run it down until you get the low battery warning. Then charge it back up.
Battery life will likely be pretty poor for the first week or so, then it will normalize.

Deep discharging (to 0%) is about the worst thing you can do to a LiIon battery, because it "hurts" it much more than several shallow discharges.
Also, like I said before, battery capacity won't in any way rise or "normalize" over the first week.
Battery life is poor the first days because you use your shiny new device all the time (i.e. more than later). It's like that for all of us.

My battery life sucked the first few days, It got better though. It really only seems to suck it down if it is hunting for a signal constantly.

If you are using your phone a laptop replacement and are surfing the web constantly, expect it to die like a laptop.

You also need to try this manual battery calibration:
http://myhtcdesire.com/tutorials/how-to-improve-your-battery-life-calibration-tutorial
After I did this, saw the battery reading 99% and 98% more often rather than straight to 96% after charged.
Originally, it was suggested by HTC tech support. I did that once every six months or so ... And my battery level is now improved. Screenshots will follow in the next post.

Not bad?
Sync is off btw. And this includes using Maps 2%.
At least with my usage pattern, I am more or less satisfied.
I wish Google fixes the high Android OS Keep awake time!

You need to remember the only thing relating to battery life is not just the battery, it's software as well, hence calibration. After about a week or so your phone gets a "feel" for your battery and gets more battery stats, so it's more accurate with it's readings. That is a proven fact, you need to think about all things.

It is quite easy to gauge a Lithium Ion battery. 4.20 V = full. 3.60 V = empty. Your phone can read the battery precise to 0.001 V. The curve isn't linear, but it's well known what voltage relates to the exact capacity left in the battery.
There's really no room to "feel" anything there, just simple math.

I consistently get 15-18 hours of use out of mine with the extended battery.
But to the OP, if your screen is taking up 60% of your battery, it's always on, your battery is gonna die, it happens. Your battery doesn't get "better" with time. It seems that way because you aren't glued to the device 24/7.

Mine was god awful when I first got it but after a week or so it got much, much better.
I have the GSM version though.

60% screen time gawt damn! Did you talk to anyone that day?

Google need to run classes on how to read the battery consumption pages. 61% screen means that the screen used 61% of the total battery used, not that the screen was on 61% of the time.

Battery...hmm not bad

So I 've been wanting to really test how long my battery could go with minimal use.
This included...
about 45 minutes of 3G tethering
and about 13 hours on 3G. 4G was disabled the whole entire time
As you can see it was idle a lot, but I almost got 2 full days on stock battery. So no complaints.
Part of me feels like if it was not for that 3G tethering maybe I could have got 4 more hours+

Not bad indeed.

Would rather use my phone and have to charge when I get home then leave it in my pocket all day.
Also your wifi was toggled on the whole time... that would have saved some battery.

That sounds pretty dire....are you running at full brightness with Wifi and bluetooth and the GPS on (happens e.g. if you enable GPS for apps and then open Facebook) and no screen timeout while running the camera?
I've had an hour of screen time, and about 9 hours of screen off; I've not had it on to charge at all today, and I'm at 60% battery.
If you go into settings/battery, what else is keeping your phone awake? In other threads, people suggest installing 'Better Battery Stats' (nb, cheap, not free) and posting screen shots of the kernel/partial wakelocks. I can't interpret them myself, but others can...

The only complaint I have with this phone is the massive difference between hspa and lte versions in battery life. Other than the razr maxx no late phone has acceptable battery life including the nexus. To get 5-6.5 hours screen time on my nexus versus friends 2.5-3 on an lte version is just crummy. I know some people just have extra batteries but that short of usable battery life is just too much of a hassle for me when I'm out and about. I would be forced to get a huge ugly seidio battery if I needed to move to Verizon. Even with 4g disabled the Verizon/sprint versions don't get the screen time I get with my hspa nexus. I really hope lte radios get more efficient and battery tech gets better. Removable or not, all phones can be made as sleek with a huge battery if manufacturers wanted. The maxx is proof of that.

I am giving my machine a hard time every day. Usually it ****s up after something like 4 hours. That is much better than the old machine I had. However, it is not good enough cause I work for 8 hours. So after the midday break in the canteen there is no more angry birds for me. I think of getting a second machine, one for the morning and one for the afternoon.

Lol, how's this for on screen time on a stock battery? I just managed to get the screens before I had to charge it up, It's the longest I've gotten with my ROM and kernel combo. Last screen shows it's the ~1800 mAh battery, the third line down reads 35/1750 mAh.
*Edit* Hold the phone, 1400 mAh is stock, right? My 'stock' battery is 1750mAh... How does that work?

Is everyone else getting strange battery drops? When the battery is at 19%, it drops directly to 15%, without going through 18,17,16. Is this happening to you or is my battery screwed up? It's been doing it for weeks now so I don't think it's about lack of battery training

This is with a genuine 2000mah extended battery, minimal use over a long weekend. This is also with emails, facebook etc all polling at 30 min intervals, wifi on but not always connected and screen on auto brightness. I had also conditioned the battery by fully charging and discharging about 5 times when the battery was new.

Battery reviews

I know the HTC One has been around a while on other carriers. Has anyone seen any reviews on how long the battery lasts?

I saw decent battery life in other reviews. One thing that caught my eye as a negative was that it had very slow charging times compared to other phones.

The slow charging time was in an early 4.1.2 build. It has been fixed though already in a previous update.

I read they turned off the fast charge mode for it, I think in an effort to make the battery lifespan last longer.

I read that it slowly charges the battery on purpose. It allows the battery to last longer since it's not removable. Apparently the fast charge fries batteries pretty quick.

Fast charging a battery phone is not really going to fry it... but there is truth that if you slow charge a battery, it will last longer.

I had the HTC One on T-Mobile for a while before switching back to Verizon and it got through the day with moderate to heavy usage. Overall you should be able to get a day out of it at least

What was your screen on time? The only other reason I can think of that contributed to this was all the setting up, syncing, and downloading that you may have been doing on this first full charge (unless you did that all of that prior to this full charge)
Edit: Nonetheless, thanks for sharing. Hopefully it is indeed going to be much better than that on a regular basis.

It'll be a few weeks before I can tell if the phone's batter is any good. I'm spending a lot of time on it.

All I know is that in the first few days to a week of me having a new phone, I get horrible, HORRIBLE battery life. Why? Because it's shiny, it's new, it's interesting!
Give it a few days to a week and you will be back to mostly normal usage. I know that after the initial new phone excitement goes away, my battery life usually doubles.
Not to mention the battery cycle break in. I'm not sure if it's real or not, some people say it is, some say it isn't, but apparently it takes a few charge and discharge cycles for your battery to get to a normal state?

I read somewhere (pretty sure anandtech) that with these new batteries, it is advised against fully discharging. The optimal state is to charge it when it hits 75% ish.
If a battery dies, it dies, but you should not be purposefully killing it. I'll try to find the article, but I'm busy at work right now.

I don't know where you heard that, but for Lithium Ion batteries, over-discharging happens when you are around 2V or less... most phones will turn off when the battery gets to around 3.2V
Fully charged is roughly 4.2V
Most of these batteries are good for 250 to 400 charge cycles, It doesn't matter whether you are at 1% or 80%, the phone will stop charging once it gets to 100% since you cant trickle-charge Li-Ion batteries

Battery Reducing Quickly?

Hello everyone, new to the forum since I just picked up my note 10+ and thiught this forum seemed more knowledgeable than others for battery issues or issues in general. I dont really know if it's an issue but I'm curious of how others people batteries are acting for their note 10+'s. Mine died a few hours ago and once it hit 100% I removed the charger and didn't use it for just over an hour and I noticed my battery went down to 2%. I have my always on screen on of course, most of the apps were dead and I did optimize the battery in the settings while my phone was charging then stopped using it until it charged fully. So I had no apps open and I had a version of battery saving on. I did medium but left the higher res screen on including the cpu at 100%. Would this cause my battery to go down 2% in an hour without any use?
For a side question, is there a better way to get the most out of your battery? I always thought it was let it die everyone inna while but I read recently charging it to 80 then letting it down to 60 and back up to 80 and repeat is the best? If that's true, how do you keep that up and how long will you need to keep that before normal chargers?
Thanks. Hope someone can help

If it went down 2% in an hour, that's 50 hours of standby plus always on display. That's crazy good.

Best way to go is using normal charge an never let the battery drop below 20% forget about trying to maintain certain range (60-80), it will just drive you crazy

If I put my iPad mini to sleep at 100%, I wake up the next morning with 100%. Maybe 99. But usually 100.
That's not the norm, and it's not perfect apples to apples, but it is possible.
Also, 2 days of standby with zero use is not unusual, but definitely not "crazy good".

So besides that little fight you had with the other forum member (lol) I appreciate your comment. But there seems to be back and forth, one other person says its good, another says its not. (the one I quoted below). Just seems weird to me that with no open or running apps and just the always on display running that it went down in an hour in 2%. Searching around, people saying losing 1% In an hour with the same set up, no running apps with AOD is bad. I kind of agree since its not truly in use. But unfortunately I cannot find any battery standby tests from Samsung or anyone else to confirm it.

I agree with you more honestly that it shouldn't be going down that fast in an hour with just the AOD running. I didn't have any apps running once it 100%, I was on it while charing it to around 50% but then once I knew I was putting it down for a while I ran the optimization and had the phone kill all the apps. When I saw it go down the 2% I did check out the apps using the battery and the AOD was the only thing listed. Maybe I didn't charge to a full 100%? even though it said 100%... Ill check it out tomorrow once I charge it fully again, today I was charging it up and down most of the day sadly. I try and keep most apps from not running in the background, some I do need though like for my IoT devices needing to know my location, I have yet to change that to just using LTE as my location GPS, but that was not on last night all. Ill try out the sleeping apps though, I didn't know there was a setting for that. Thanks again

AOD typically consumes 1%~2% in my past note devices(7,8,9)

Battery optimization takes a little bit so if you just started using the phone give it a few days.
Also, package disabler or ADB can be used to turn off any major things that you are not using (i.e. Bixby or DeX).
Regarding Cell life: Yes between about 30% and 80% are the optimal percents. That doesn't mean try and always keep it there, that would just be silly and unrealistic.
However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.

Reporting my battery life. I guess this is truly an all day device.

Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

However, it is important to be conscious of this. For example, don't leave your phone on the charger for days on end sitting at 100%. Don't leave your phone in a drawer or a backpack with 0% in the cells.
Cells are technically damaged (or worn would be a better word) every cycle. The most damage comes from when the voltage drops to its lowest point and its highest point. (i.e. 0% and 100%)
For example, if someone were to charge a LiPo or Li-Ion battery only between 30% - 80% for an entire year and another person with the same phone always went down to 1% and always to 100%, the latter phone would have more cell wear thus it would not hold as much power.
Once you learn of this and become conscious of this then you tend to adjust your habits. All other myths and theories about battery calibration have really not been a thing in many many generations of Android. While you can screw up battery calibration through a service menu, rarely (if at all) a battery loses calibration. Most people start seeing battery wear and think its a calibration issue and then seek ways to fix this. At that point, it cannot be achieved because there is a physical change to their battery which can only be refreshed by getting a new battery.

This is useful, thank you. Never knew not discharging device is the way to go but we all learn new things every day. I'm at 65% right now, when waking up at 6am with 95%. Wireless android auto for about an hour, plus okay-ish use. Ill make sure to charge it up to around 80% tonight.

Give it a couple days to settle. The first three days, mine got pretty bad battery life. Then yesterday I got almost 10 hours of screen time after using it pretty heavy all day. Mixture of Facebook (battery hog), Internet, texting, emailing, and using the camera (also a battery hog). What finally killed the battery was me downloading, installing, and uninstalling multiple versions of GCam trying to find one that worked well enough to use. I finally found one before my phone hit 0%.

Thanks, I think I am seeing a bit better today after having it for 4 days or so now? Ill follow the above quote about calibration and go from there.

Reporting my battery life. I guess this is truly an all day device.

Over 8 hours screen time is great, best I've gotten so far is 7.5 hours

I just wanted to throw my two cents in here... My battery life is pretty terrible in comparison to my S10+. Trying to find a rogue app of some sort but I just hit 1% with 12 hours off the charger. Keep in mind that is not 12 hours of use. In fact I used it for about an hour of total screen time today.

Yeah I came from an S10+ and noticed my battery on the N10+ was pretty bad in comparison.
I did restore everything from my S10+ though, not a clean install of everything.
Wonder if that may be causing issues.

Is everyone having problems on Verizon?

Quote " Last night I even scheduled it off and had no running apps and medium power saving mode fully on and lost 5% battery in roughly 7 hours with no use."
Unless you put it in airplane mode, your phone will keep connected to cell tower (or wifi if you have wifi calling) otherwise you won't receive calls and messages, so there is no such thing as phone with no use, and if you have weak signal or some interference your battery usage can increase drastically even in standby because the cell radio will try to connect at full transmit power. And then you have all those programs running in the background, God knows what they're doing. As others suggested disable programs you don't use, also you can force close programs that you don't use often. When I had my older Note rooted, I optimized it so well it would run 2% down per 8 hrs overnight, but it took some effort. Biggest problem is to know what to disable without loosing functionality for stuff you need. Give it some time for people to learn more about new phone. BTW my 3 day old phone has 435 apps and services installed and most of them I have no idea what they do.
