I was using the phone for about 2.5h with wifi on browsing reading some news and got the battery to 38%. Then I have activated the power saving option and locked the screen and went to bed. Now I just woke up and see that my battery is at41% wow. Did it charged up or what has happened?
An inaccuracy of the battery meter? It defenitely did not charge itself. That's physically and chemically impossible.

It's weird how it constantly increased from 38-41 it was not just a sudden jump... I got sudden drops in battery after a usual reboot, and but never a slow increase....

Actually yes it does happen.. I really can't pinpoint the reason though.. After heavy usage the battery does drain for a while after the usage and then since no usage some power is restored.. Same like AA batteries.. Example: Use AA batteries on a device till the device switches off.. Then leave the device idle for a while and battery will be usable for sometime though the device had switched off earlier due to complete drain..
I'm not an electronics person. So i dunno how or what makes this happen :silly:
My battery life was fcuked: losing 40%-%50 overnight while it was inactive sitting on the nightstand.
(Factory reset did not help at all!)
Now after futzing with the WIFI setting, last night I lost only 5% total in 8 hours sleep time.
Furthermore battery read 18% remaining at 10:30 PM and still read 18% at 4:17 AM.
Now this is more like what my iPhone 6 gets while sleeping.
What seems to have fixed by battery woes.
I changed the (Advanced) WIFI frequency setting from Automatic to 5Ghz (which would not work at all) and then to 2.4 Ghz only.
As of today I have 87% remaining after 3 hours of casual use (after charging to 100%.) Previously (for the past week since installing Lollipop) I was losing about 25% per hour during casual usage - ridiculously bad battery life.
Hopefully this will work for someone other than myself. I had just listed this thing on Craigslist because I cannot use a phone with 4 hour battery life.
Good luck.
Just set it to the same WiFi setting, will get back with screens.
Thanks though, I have brought this phone recently and thought it was only me getting bad battery life :\ I've had to charge this phone more than I did my nexus 4. I brought it off someone after they had used it for 9 months.

Mine loses 1 or 2% overnight with wifi left on. Luck of the draw i guess.

try setting it back to auto and see what happens. IE, try to replicate the issue and the fix.
For me, I went back to KK 4.4.4 factory image and took OTA seems to fix the wifi idle to just same as OP overnight (~5%). But after some use, it can drain quick but not as quick as I was on custom ROM (all kinds I tried).

This can happen when the phone is being moderately used before a longer idle period. The battery percentage will actually go up to compensate for the earlier usage estimation, giving the illusion of zero drop over night. It becomes clear after seeing the graph and the line going up only to drop down to the pre-idle level.
Kind of annoying since I'd like to see how much was actually lost over night. Just something that happens with the estimation process that is our battery level.
I recently switched from 2.4Ghz only back to Auto mode as it seems the WiFi speed drop issues are no longer present on my particular home network. No battery drain or issues yet but I will keep a close eye on it. Thanks for sharing.

I think your statement is true, as I noticed that with OTA updates, my idle over night is very low. However, upon using the phone the battery immediately starting to report drastic drop in percentage number. I mean this is cruel as in it gives us a false sense of battery consumption over all lol.
I will try it thanks
I'm going to give this a try. I've been using an app to turn wifi off when asleep but am still getting higher drain on wifi with the screen on than should be. Will report back after a day or two.
Personally I don't think they fixed the wifi miscellaneous drain and just hid it in the usage stats. My battery life has never been the same since the final dev preview. Luckily I'm always near a charger.

Right, I did read the OP and actually did make the same adjustments. However, I didn't see any improvements on my KK 4.4.4 upgraded to L via OTA in terms of idling overnight. My idle stats are very good even prior to the adjustment mentioned and same post adjustments. However, the freaking issue is when I started using the phone.
I think it is varies wildly for each user and their phone.
" the freaking issue is when I started using the phone.”
Indeed, this is another issue with this phone. Battery is too freaking small.
At this point i am back on my iPhone 6. iOS is a bit rigid for my taste, but the thing is fast, great screen, and runs two days on a charge, call quality is superior, louder speaker, etc!
Battery life is critical, yo.

I feel ya, I tried a 5s and iOS 7 out for about 6 months because it looked nice. Had great battery life until I had to jailbreak it to get it to do what I wanted (which is stock/non root stuff on android) and apps from cydia rocked my battery ;-( then it was like why am I having to tweak the crap out of this phone to do simple things I want that shouldn't be a big deal in the first place? Finally just decided to come back to my N5 in the end.

This. I hate how much my battery drains when my screen is on. I'm convinced some of it is Lollipop though. I got a feeling it is also related to the memory leaks.

Agreed about ios, but it is getting better. The notificatiins just got a lit better....little things are slowly improving.
Something that is GREAT on iOS now: voice to text is screaming fast now, and extremely accurate. I rarely type emails and texts now. No kidding!
I went back to 4.4.4 last night - as while the idle drain was fixed with these settings, the overall battery life while using the phone under LL is still relatively miserable.
4.4.4 seems a bit better...
Now I see that 5.0.1 is apparently being released in the next day or two...we shall see. So far the release notes say nothing about a battery fix.
On 4.4, I observed a massive reduction of WiFi wakelocks by setting static IPs in my home network. So if you have problems, give it a try.
is it possaible some app drain it in overnight?
Does no one else realise that a major OS update needs to "bed in" for a good few days? The battery life performance is a lot better on LP. I've an HTC desire 610 though and it goes days between charges. It's a 420 battery but 1/4 hd screen. You take your choice of features and find your phone/s
So, this is a strange issue. When my phone dies, it will die when it says I have 5% of battery. Sometimes, it will die at a reported 4% instead. This randomly started one day. I got the 5% remaining notification, and suddenly, my phone shut down. Ever since, I can't get below 4%. I've tried to turn the phone on, but it acts like it is dead.
I'm not sure if it's just reporting the wrong percentage, or if it's actually dying early. I've tried flashing different ROMs, wiping everything, and no change. I've also used Battery Calibration to delete battery stats, with no change. I've had issues with other phones dying a little early, but battery calibration always fixed it, so I'm at a loss. Has anyone else experienced this? Is there anything I can try to fix it?
Definitely have this issue too. Dies at 4% strangely enough. Thought it suppose to croak at 0% lol.

Its just not reporting the percentage properly. MIne does it too.
The phone will shut off when the *voltage* drops below a certain threshold, regardless of what the actual "percent left" indicates.

In theory, the percentage display is supposed to calibrate automatically to the voltages... however it should be noted that the battery's *minimum* voltage does need to be programmed in at some point in the process, since the shutoff voltage can NEVER vary. Most likely, the problem of shutting off at 4-5% is a matter of "feel good" battery levels, much like some lingerie stores will label items with the "next size down" or "next cupsize up" to make women feel smaller and bigger in the areas they want. It basically bumps the full scale percentage display by an average of 2.5% UP, which can lead some less observant users to viewing that as a slightly improved battery life. Most people will plug in before it hits 5%, so won't even notice this.
So, basically, that's just how it is? I've never had a phone that was so off. And I still don't understand why it went down to 0% or 1% the first few weeks I had it. It's not an issue, it's just strange.
mine shuts down at 3% every time

My n5 shuts down at 1% every time on lollipop. Chalk it up as an n6 "bug" if there's chalking to be done.
I also have this issue and posted a similar thread about it a couple weeks ago. Given that any other device I've owned has been able to consistently reach 1% before shutting off, I think this is either a Lollipop bug or specific to Zthe Nexus 6.
I'm going to test it with my Nexus 9 and ask a buddy about his Moto X 2014 and report back.
Mine died at 9% sigh...

That's the funny thing though, because it never did that. It just aligned shut off with 0%
Happened to me once so far, hit 4% and it shut down unexpectedly. I chalked it up to the kernel at the time, as I had flashed a new one the night before.
Maybe it's intentional?
The Nexus 4 could sometimes be a real pain to reboot if you let it go completely dead. I suppose it's possible Motorola/Google are preventing complete depletion of the battery.

Complete depletion of the battery would literally lead to an explosion upon recharge. That's why all lithium based batteries have an additional 10 - 20% below the battery chip shutdown voltage.
Also a phone that shuts down at 5% is more likely to automatically shut down than one that shuts down at 0% as its a little more unpredictable.
now i have the opposite problem. my phone keeps charging after it hits 100%. i use current widget, and watch it when im charging. and current keeps coming in after its at 100%. it will depend, but sometimes it could still be charging for a half an hour after it hits 100%. but then again, it could stay at 100% for 30-60 minutes after i start using the phone on battery again :silly:

I remember the battery calibration trick on Tue original HTC desire. Turn the phone off and charge to 100 then reboot and charge again. It got the % out of whack and gave a false perception that the battery lasted longer as it stayed at 100 for much longer than it should do.
I let it charge to 100% around 1am, unplugged and work up at 730am. Battery was on 85%. No use at all.
During regular use it seems to drain quickly. I've disabled probably 20 apps.

I went to bed around 1am as well, woke up at 9:30am. I also disabled around 20 apps. Bedtime battery was at 95% wake up battery was at 85%. I dont think thats too bad at all.
I'm pretty happy with my battery life so far
Does Verizon have an immediate ota update like tmobile? I didn't he update right away and seems solid enough. Not as good as my g3, but way smaller of a battery in the edge.
Disable the Amazon App Suite from Applications manager. This has been the culprit for every carrier on the S6. If you use Amazon app store, download it through amazon directly (it is a different app than the one included with the phone).
Your problem will be solved right away!!
Also, the Edge display (not the contact color part, but the clock and news feed) is a battery drain.
another problem with alot of s6 owners, aside from the stock amazon app, is there has been alot of battery drain if using wifi. I had wifi on most of the time and noticed a drain from cell standby... once you turn off the wifi that never comes up and drain is perfectly fine... no cell standby battery drain...
My battery was terrible the first day, ok the second day, and far better today. Seems like it has a time it needs to settle down.
I haven't gotten >3.5 hours screen on time yet. Which kind of stinks.
Disabled a few more apps today, will see if they helps any.
Sure have been getting use out of the quick charging though.

Sorry, I didn't look at that before I plugged it in.
Almost 6 hrs of screenon time use, Netflix for 30 mins...Facebook and texting. Screen set at around 30% brightness. Happy with my S6.
Not disappointed in how short the overall battery is...it does what I want and need it to do.
Yesterday my phone was dead from 6am to 6pm today at 5pm still have 47% left and I definitely used it more today. Better with age?
Hello I just gave my first full charge to my phone and the cell stand by is at the top, is there a way to avoid this or we going to accept to live with it, thanks for your help.
my battery wasn't too bad either
I just bought my Z3C a couple of days ago. First thing I did was charge it fully and then I started using it. It went from 100 to 0% in about 21 hours. During that time a SIM card was inserted only during the last couple of hours, but I did use the phone fairly often. The attached thumbnails show the details.
I did notice that it almost loses no charge in standby. But today I noticed an increased decline during screen on time after standby time. See last screenshot attached.
I expected more from this battery based on reviews and Sony's claims. Is this normal or is my battery faulty? While some here report similar numbers, others seems to get a lot more out of their batteries.

You shouldn't expect more from this battery based on reviews, you should just look at what some people got out of their phones.
Give the phone some time to settle in. And don't forget that it's almost summer for us now, more sun means using the screen at a higher brightness so that will also have some impact on your battery life.
Look what kind of useless apps are running in the background and stop them and don't worry about the estimate, it really doesn't mean much. Right now my estimate is 9 days, because I barely touched my phone.
I really don't believe in such a thing as faulty battery. Charge your phone, restart it and see how it reacts then.
Is Stamina mode enabled? If not, then what you have is typical. Getting a full day out of one charge is about all you can expect from a smartphone without some form of battery saving measures enabled.

Here are my results:
http://forum.xda-developers.com/showpost.php?p=59933232&postcount=48
At the moment I have 3d 10h battery life and still 40% left. Tomorrow after work @ 12 our time I'll charge my phone again, so that's almost 5 days.
(But that's with a lot of idle time)
(Vergeet geen apps te freezen en je telefoon te restarten)
With moderate usage, you should generally expect just about 2 full days of battery life from this phone. And that is with Stamina mode enabled to help the phone sleep when the screen is off. However, this is not accounting for any extreme measures some people take to extend their battery life (e.g. disabling background data/sync). Once you remove these features, you're no longer using the smartphone as it was intended, so it's not a fair comparison.
I can easily get 2 days out of my Z3C before I think about charging it. And I've never used Stamina Mode.
I guess I could install some app to monitor battery usage and stats but I'm not that bothered tbh.
We all manage a variation on the smartphone thing, in terms of data, wifi, gaming, emails, browsing, texts, calls, etc, and its slightly different, in terms of use, from one user to another.
I'd echo the sentiments of another user who said give your battery time to settle in. Give it a full charge, discharge cycle a couple of times, and don't worry too much about it!
Peace.
Thanks for your feedback, guys. I'm currently fully charging and discharging my battery. Several cycles complete.
The best result I've gotten so far is a little under two days with moderate usage and thorough measures to increase battery life. I turn on airplane mode when I go to sleep. Stamina mode is also enabled, but only the reduced performance part. I'm also using 2battery, which turns off WiFi and data when phone is in standby, and turns them back on briefly every 15 minutes. (While I agree that turning off data connections defeats the purpose of a smartphone, I also believe that there is no need for a constant connection when I'm not using my phone. 2battery achieves that. Although I must say it doesn't seem to kick in a lot on lollipop.)
So despite these measures my battery seems weak compared to yours. Anyway, I'll be taking your advice and I'll give it some more time.

You need to be rooted tho (Which shouldn't be a problem)
Are you using GPS or is it always on?
Your battery is fine. You probably lost some standby life when you put a SIM in it, as that would cause your cell radios to begin seeking your carrier's towers.
Do activate Stamina mode if you haven't already done so.

Well yeah of course GPS uses a lot, especially when you don't use it, it's just wasted energy so to speak.
Greenify lets apps go to sleep earlier/faster so that they can cause less wakelocks.
With Greenify and DS BS I don't need Stamina mode and many of us are even wondering if Stamina is working most of the times, these two apps I'm certain that they work.

Well, I've been keeping an eye on it for the past week, and I seem to be losing next to no charge when screen is off. My phone is in deep sleep over 75% of the time. (According to Better Battery Stats)
I do seem to be losing 1% charge for every 3 minutes or so while my screen is on. Is that normal? We're not talking gaming or anything demanding, just some browsing and messaging.

I think the best way to measure if it's correct or not, to for example put some movies on your phone and let them play constantly, see how long your phone can manage.
You should get at least 6 hours of on screen time using that method
It's too late to say this, but after getting a new battery/phone you should always drain it fully and then fully charge the battery so that the battery has a proper charge (it saves a lot of battery capacity and battery life)

Good that it's too late, because it's incorrect. This suggestion dates back to the days of NiCd batteries which had "memory effect". Li-Ion batteries found in modern devices for at least the last several years and definitely since the beginning of Android don't have this effect, but have something else - when you drain the battery completely, you cause damage to the battery cells, and it can withstand only a few of these full-draining cycles before losing significant part of its charge capacity. This is why both laptops and phones have protective measures to turn off the phone completely before the battery reaches a dangerous drained state. And as the batteries go bad and their "low percentage" scale becomes unreliable (not able to sustain operation currents with low charge), these protective mechanisms can fire too late - which in turn can cause storage corruption to occur, if the power is lost gradually and not abruptly during operation.
To another poster that doesn't believe in faulty batteries - he better should. Batteries go bad with time and charge-discharge cycles, they're harmed by complete discharge, and can go bad in several other ways. However, I wouldn't expect a battery to start its life damaged - quality control of the manufacturer should prevent this.
My results for reference - I have ~2-3 hours a day SOT, 1-2 hours tethering, have several phone calls, messages and mails - and the phone is usually upwards of %50 at the evening. I have to run it through ~4 hours navigation to reduce it to sub-20% towards the end of the day, and actually see no reason why a smartphone should hold any longer - it's routinely recharged every night. The main problem for smartphones, to me, is not surviving till the end of the day.

Thank you for sharing, but that advice is about as outdated and useless as changing your car's oil every 3000 miles. Batteries simply don't work that way anymore and some studies show that battery life is actually reduced when you perform full charge cycles instead of shorter recharges throughout the day.
Edit: looks like someone else best me to it :-/

Actually sorry to break it to you, but you are wrong, Li-ION batteries do have a memory effect, since about 2013, researchers have found that they do have memory effect.

Well, thanks for showing me something new. However, this is a very different effect from NiCD. While in NiCD this effect would prevent the battery from taking a full charge when repeatedly not discharged fully, in the research you've showed there are 2 very important points:
1. What matters is not the discharge, but rather a charge. Charging not fully is a way to trigger this effect. On the other hand, discharging partially (like in NiCD) doesn't trigger it. This point makes the info, while indeed interesting by itself, irrelevant to the current discussion, and keeps your previous suggestion wrong and bad for the battery.
2. If kept charging a bit longer - the battery would still charge fully, though it would take a different amount of time from the expected. For night time charging, when the phone is connected to the charger for several hours more than it's needed to actually regain the charge, I'd guess that most of the time it does the job of filling the battery properly even after an incomplete charging cycle.
[edit]
After reading it again - actually there is a third point that makes your suggestion even much worse than I thought it is:
This memory effect that you've pointed to is triggered by having an incomplete charge followed by a complete discharge. That means, incomplete charge with incomplete discharge don't cause it - a complete discharge is required. And when you receive a new phone, the battery isn't fully charged - so if someone goes by your suggestion:

He would actually be triggering the memory effect you've linked to, on its bad side!
And just for reference, here is a recent article from 2015 that is far less technical, but does a great job of explaining battery behavior in practical terms that average people can understand:
