Hi all,
Posted this in another thread, but I'd like to garner some more opinions.
Brand new Galaxy Nexus, 2 full charge cycles.
7h 2m 3s on battery.
1h 15m 30s screen time on.
Battery now at 49%.
Top culprits - screen 48%, Android OS 22%, phone idle 7%.
This is a lot worse than I expected. Am I over-reacting? And how does this match up to other's experiences?
Brand new Nexus S?
Wrong forum?

Sorry, I wrote the wrong phone name stupidly. I do, of course, have a brand new Galaxy Nexus
It's hard to say really, battery life depends on a lot of things - use, how much time spent on 2G / 3G / Wi-Fi, what accounts you have syncing, sync frequency, etc.
I would also say it would take at least a week of "normal" use and charging before the battery settles in, and you start to get a real sense of how it performs.
FWIW, I am pretty happy with the battery so far. It gets me through a day, which is more than what could be said about my Desire
Would you say the battery life is actually better than the Desire? I'm running CM7.1 on mine and that can easily get through a day
Battery depends so much on the use case ..
A friends charges his Nexus S every 2-3 days and I always thought "how he's doing it?"
I usually got about 18 hours with my phones so far and I would be quite happy when I get 12-14h with the new Galaxy Nexus and it's bigger display.
I think we've to get used to multiple chargers, portable charger or a 2nd battery until we'll see new battery technologies in a few years.
I haven't been able to find any threads that already cover this. There are several reviews, users' opinions etc on how long the battery in a particular smartphone lasts, but it's always struck me as odd that this information isn't easy to compare - it could lead to name-and-shame for particularly bad phones or encouraging results for those manufacturers who actually cared & made improvements.
I've found a few people who had the same idea, and one of them (being a much more web-capable person than me) actually made a website for this purpose. I really don't want this to sound like advertising, because the purpose isn't to make anyone any money, but simply to centralise this kind of information and have some (arguably) more meaningful stats driven by and for the benefit of everyone who wants to know.
If you think this could work & be a good idea, please take a look at the site - http://www.wewantbatterylife.com/ . If you think it's a rubbish idea and/or have objections, flame away.
the li-ion batteries normaly have longer life than the old phones...so it will last enough time..u'll probably replace your phone before the battery dies Probably u can ruin it with overclocking your device or something..but draining is something else
ps: im trollling again :O
Hehe, I meant battery life as in "how long does your battery last from a full charge until it runs out?", but yes, mini-troll It's all good..
Hi,
I have another question about batterie life. I don't know if it has been already treated somewhere else in the forum.
I will receive the 2000mha batterie today. What is the best way to calibrate it?
Fully discharge it then full charge or full charge before first use?
Thanks for you help!

my battery in nexus s long about 4 houres in full use , that is problem ?
what can i do ?
Nice site, and it will only grow more useful the more people input their info. Although looking at the results, some of those 30+ hour claims seem outlandish.
my stock galaxy note battery takes me 6 hours to lose 50%. hope it could last longer.
On my Galaxy S running ICS 4.0.4 Dark Knight 2.2, my battery lose about 25% by day. But with light use (1 or 2 calls, some SMS, GMail sync, ...)
really miss the days with my old nokia which i only needed to charge every two or three days haha.....

my phone keep charged almost 1 day
I don't know if it happen for someone else but i noticed a sort of "bug" with my HTC HD7. (Bought in December 2010)
If i reboot my phone when the charge is at X%, after the reboot, the charge level will be ~10% less than X ... and the phone will stay a very very long time at this percentage.
(For exemple, if after a reboot, i'm at 75%, the battery could stay at this level for all the day)
So as I imagine, it decalibrates the battery level and to make a new time the calibration i have to let my phone fully discharge and fully recharge to solve this bug.
Strange ...
(Sorry for my english guys, I hope i can be understand)
It seems that smartphones need more juice daily. However if you disconnect the mobile packet data whenever you are in range of WLAN you might get 2 days with one charge.
I am actually quite amazed how well my Samsung Galaxy S1 original battery has lasted almost 2 years. When I first started this smartphone journey with my S1 I thought that it will not last one year. I am glad that I was proven wrong.
Batteries
Definetely Smartphones need better batteries, especialy after we got used on some phones to last even 4 days like I had previously Nokia C7, and after that i bought Galaxy S2, and its battery lasts only 1 day, now thats really sad
my sgs+ with a custom rom (gigabread+) is alive up to 24 h.
My I9001 is at 30% at the end of the day (connected to wifi all the time)
battery life xperia s
my xperia s last 3 days with making some calls abou ta half an hour surfing on 3g a day and sometimes a game but when i use it a lot is lasts about one day and a half
HTC HD2 on nand android does ~4-6mah an hour on standbay, depending on torture i give it, it lasts a day to a day and half
My Samsung Note (stock 4.0.3), WiFi on all day, and average use (business mail, whats-app, games, some browsing)
after 15 hours the battery is still 40%~50%
i use SetCPU, it throttles up the CPU if its needed, at idle it runs at 200 MHz instead of 1.4 GHz
My SGS2 can last almost 2 days without using data. Its pretty good on battery
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...

How is the signal strength where you spend most of your time?
When I'm at home, it's crap, and I'm about in the same boat as you.
You can get the better battery stats for free if you can locate the guys thread here on xda. But I recommend at least donating to him for such a useful app.

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.
Yay, another super 1337 battery thread.
Check out my super 1337 battery savings with a stock battery!!!

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.

Hello all,
I hope I'm not beating a dead horse by asking this because I have searched this site as well as other places around the internet and there seems to be alot of information out there concerning how to charge your phone battery. But every time I read something, it seems to contradict the last thing I read. So I wanted to pose both viewpoints to the experts here in one place and hopefully get some clarification.
I recently got the Note 2 and am really happy with the phone. One of the biggest and most welcome surprises is the terrific battery life I have gotten so far. I am coming from a HTC Sensation and while I liked that phone, I always felt like the battery life pretty much sucked. When I first got the phone, it would barley get me through the waking hours of the day and that was only if I used it sparingly. Over the course of the nearly two years I had it, the battery life just got worse. I typically would leave my phone charging all night as well as in the car during the day if I had heavier use that day.
With the Note 2, I am seeing much better performance. I can easily make it through a whole day starting at 6am and by the time night comes still have over 50% charge remaining. I am not a heavy user but I have found myself using it more, trying to deplete the battery so I can charge it at night. My problem now is I can make it through one day with no problem but to make it through two full days may not work as well. I feel if I don't charge at night when its still around 50-45%, the next day I may need to charge right in the middle of the day when I need to use it or am not by a charger.
So my question is what is the best practice? Is it best to fully charge then fully discharge, and if so does it need to be a regular habit or just the first few cycles? Do I need to remove the phone from the charger once its fully charged or will an overnight charge be a safe option? If the phone is only at 40% or more is it ok to charge it? Are there any other battery management practices I should be aware of?
Thanks in advance for your help
dont read too much into battery charges...charge as you like...........at home, in car, connected to pc...........lol..........the battery will last for 2-3 yrs well...then if you feel it is dying, it has a removable battery.........you can always change the battery, buy a new one...they are cheap...
for ex:
you get ~1200 cycles if you charge from 40%-90%, but you will charge twice a day (2 charges a day will last ~400 days)
you get ~400 cycles if you charge from 10%-100%..charging 1 time a day will last ~400 days again

The above is the only proven effect on our batteries. The rest is handled by the battery itself.

Honestly ive always charged my phones however and whenever I liked. Overnight and at varying parcentages. Never noticed any battery degradation at all. My x10 battery seemed the same as the day I got it after 2 years.
I figure any detrimental effects will probably occur after 2 years of bad practice at which point most people would have a new phone anyway

I think the batter is the weak link in this phone. Actually, I think it was that in my Note 4 too. After a good year, my phone started bootlooping and it was the battery's fault. I am not too confident in Samsung's batterys, not because of explosions but because they seem to be not the best. The problem is, if we want to change Note 7's battery, it will have to be done at the service center. So I'd like to keep the battery in good condition for as long as possible.
I have read it is best to avoid fast charging. I also read it is best to keep the charge between 40-80% and not let it charge over night. And to only let it drain to 0 and charge to 100 once a month to recalibrate it.
Do you guys think these are good tips for the Note 7?
I also read that first time I should have let it chargefor 5 hours, which I didn't first mistake there? Thanks everyone.

From what I have researched from chemical engineers who design batteries etc the best thing to do is not allow the battery to discharge below 20% and not charge it over 90%. Fast charging apparently does shorten battery life but all charging methods shorten battery life. All about heat, so they say? In 'normal use', whatever that is, a typical mobile battery could last years?
In thinking about this I have owned since the early 80's maybe over 100 mobile phones and 100 other mobile devices and have never replaced a battery yet? I have friends and family still using some of my hand me downs and they are still going strong.
Appears a very hit and miss science?
Ryland
I am pretty sure I count as a normal user. I also don't think I exposed the Note 4 to too much heat or did terribly stupid things with the battery. Did I just get a bad one, maybe.
It sounds to me that you've been paying too much attention to the battery, stop worrying and you'll enjoy the phone even more.
never let the batt go to 0%, charge max at 90%, thats all you can do, and, dont worry too much, enjoy your note 7
This is off of Samsung site...
Cell phones, originally used for little more than calls and text messages, have evolved into all-in-one entertainment devices. Your smartphone plays videos, music and games, and many include lightning-fast Web browsing and a robust app library. Use these features for more than a few hours, though, and your phone's battery charge may not last longer than a day. You can coax more life out of your phone by charging the battery correctly and tweaking a few power-hungry settings.
Charge Regularly
To get the most out of your smartphone's battery, you'll need to charge it properly. Most smartphones have a lithium-ion battery that lives longer when charged regularly. Unlike the nickel batteries used in older phones, lithium-ion batteries do best when kept above a 50 percent charge. Repeatedly allowing the battery to drain fully may shorten its life and decrease its overall capacity. If this happens, you'll need to charge the battery more frequently and it may last only a few hours before needing a charge, for example.
Your battery will also perform better if you don't let it charge to 100 percent, so take it off the charger at about 80 to 90 percent capacity. Leaving the phone connected to the charger when the phone is completely charged may lower battery life if you do it repeatedly.

I've researched this and tested it for myself not saying this is the answer. I use to go 100 to zero with note 3 trying to see how far I could go screen on time. Biggest mistake I've read from Samsung and makers of lith batteries to not let it go below 60 amd it's ok to top it off as often as possible. Leaving on charger doesn't effect them due to them never fully charging they trickle charge my wife does this every night with note 4 no issues same battery for a year. You get 500 cycles of charge if you deplete 100 to zero it makes the battery unstable when hitting zero lith don't like it. You get 2500 cycles if you do the 75 to 100. I've topped off my note 7 every day lowest going to 60. I play music for 3 hours walking outside only lose 2 percent of battery. Using hotspot I lose 5 percent in a few hours all been the same the way i charge. I had 2 other note 7s I did the opposite. In a week I would lose 20 40 percent battery with hotspot music not as good either. Learn the mechanics other the battery how they work wiki it. Look at the science not opinions or articles. That helped me in the long run. I keep a Poweradd Apollo with me just in case.

Well if Samsung put that info on their page it really about says it all.
Back to stationary phones I guess. I don't want to have to take this phone to the service centre in ten months or so.

Have you read the replies here?
No device can go forever without an eventual battery change. As I said I have owned hundreds of mobile devices spanning FOUR DECADES and have never replaced a battery.
How did you arrive at a 10 month replacement figure?
Ryland
Yes, mostly they don't agree with you . And ten month figure from my experience with Note 4. At 10 months it started being weak, then after a few more months, bootlooping started and it was just because of battery. I love Notes but just don't think they have good batteris to begin with.

If you have a doubt regarding a mobile don't buy it especially an uber one like the Note 7 etc. If you are very concerned about battery and its going to cause you worry go for a brand with removable battery. No one can asses how you use your phone and how long the battery will live.
Sounds like you had a bad experience with your previous mobile and that has caused you some anxiety. All one can do is relate our experiences to you and hope you can make a judgement call based on others opinions?
I have zero reason to suspect the battery life of the Note 7 to be any weaker than my previous mobile devices. Only time will tell. The battery on my crystal ball needs charging.
I wish you well.

I try to plug in my phone when the battery hits 40% and charge it up to 80%. I dont get to strictly follow it but that's the best way to preserve battery life/performance
