I just got this recently and it seems like battery drains pretty quickly when the wifi is left on, for some reason the wifi connection stays on constantly unlike my Galaxy S2.
Is there any way to get wifi to sleep when the screen is off? Not that it's a big deal, but it seems like samsung should have thought about this so users don't have to constantly toggle wifi on and off.
Are you sure it's wifi that's doing it? I get barely 24 hours on standby with no apps running & sync switched off.
I've read that the chipset used isn't very efficient when in standby but the status reports on my 5.0 say that when in standby, 77% of the battery is being consumed by cell standby, despite the device having no cell functionality. Wifi is reported as consuming only 8%.
I've asked Samsung to comment & got a very helpful "return it to the retailer"...
I saw a recommendation for Juice Defender but haven't tried it yet.
The Battery Usage estimates for idle, standby, and wifi aren't always reliable - they assume Samsung got the powerprofile.xml right
For me - I know that wifi is significantly increasing my drain, but since it still lasts 4-5+ days of light use even with wifi always on, I don't mind.
This is for the 5.0 with the stock /system firmware and my kernel - 4.0 might be different due to a smaller battery. I see no Cell Standby usage reporting.
I've only had it a few days, but with wifi on, the battery lasts a bit more than 24 hrs just sitting there, I've turned off the wifi about half way through the battery and it seems to be draining at a slower pace now....
I'm also on stock Galaxy 5.0.
It's all very odd. We're getting around 24 hours & others are reporting 4-5 days.
I get 2 days to 5-10% almost everytime. Not much use, wifi on during day, off 10-12 hrs each night. Definitely not very efficient for such a large battery.
My 5.0 gives me great battery life listening to mp3's, the radio, podcasts and watching videos I've downloaded to the player.
However, downloading/surfing the internet drains it fast!. Much faster than I expected
I installed Juice Defender yesterday.
23 hours on I'm now getting a reported 85% of battery use consumed by the non-existent cell standby but the good news is that the battery icon is still showing full. Juice Defender in it's default "balanced" setting switches wifi off & on with the screen & it's reasonably quick to reconnect. Definitely worth a try.
Co-incidentally, I also heard back from Samsung this morning who are going to get their service centre to contact me. I'll report back on what they say.
Now on 66 hours with still a near full battery indicated so it looks like Juice Defender is the way to go.

Greetings,
First off I'd like to say that I absolutely love this device. I had the Evo 4G prior to this but about 3 months ago I dropped it on accident and destroyed my screen, then tried to replace the screen myself and it didn't go so well so I have spent the last 3 months using a Rumor touch to tide me over (). I'm happy with the Evo 3D beyond belief but I had a few questions to ask because I am not getting the amazing battery life that people have been so thrilled about.
First off I have background data disabled, auto sync is tuned down but not turned off completely (though it is turned off for things like htcsense.com and the like, only on for gmail and weather). I have adjusted the screen brightness down to around 20% but occasionally bump it up in high-light situations. I've also installed Juice Defender which helped a great deal, but I'm still noticing some strange behavior.
Is it common for the screen to be hogging the battery life like none other? I was able to go 14 hours yesterday with Juice Defender on, but i was also working for 12 of those hours and using my phone very little, so i'm willing to say that 80% of the time the phone was in standby/sleep mode (and i verified this by looking at up vs awake times). The thing that baffles me about this is that the battery usage says that the display used up 80% of my battery. How is this possible when the phone's screen wasn't even on that entire time, does the screen really pull that much power when its on?
My capacitive buttons are on full brightness while the screen is on no matter the light situation, is this as intended or could this be a defect drawing too much power?
Anyone else having battery problems?
i have issues when im at work with little to no signal which zaps the battery pretty hard, do you have issues with signal? (you can check under the batter graph, cell standy should list a percent without signal, mine yesterday was like 44 percent from being at work)
Other than that how long have you had the phone and have you calibrated the battery? It should improve over the first few charges, especially if you've calibrated.
That's odd, i have pretty decent signal here but under the "cell usage" i have 75% time spent without signal but the cell usage only was 8% of total battery use, and still 70% used for the screen. Does JuiceDefender turning off the 3g account for any of that 75% time spent without signal or is it truly phone signal loss
Sorry yeah I did calibrate the battery before the 14 hour period i was referring to.
So I just got an Amaze earlier this week, and my battery life until today was atrocious. Like full charge to dead in ~8 hours with medium usage. I tried doin the whole battery conditioning thing, running it dead, full charge, running it dead again, and have done that 3 times so far.
Yesterday, I lost 4% battery life in 3 minutes showing my girlfriend something on my phone. then 30% in 20 minutes watching netflix on my phone. Pretty much unusable battery life, and I thought that I would have to return the phone and go with a different model.
However, today, it has been off of the charger for 6 hours with the same medium usage, and it just ticked over from 98% to 97% battery life remaining.
What is your average with the phone? My last phone was the vibrant, and it had pretty good battery life. If this phone is gonna end up requiring a second battery, I dont wanna keep it. And with how erratic it has been so far, I can't just go off of what I've experienced.

make sure you are updated to the latest firmware, check for update settings from HTC on your phone..depending on my use, I can go for 24 hours of use, to 5 hours of use...I have also noticed where 4g is weak my battery gets eaten away very quickly...There is no way to tell weather you are using Hsdpa+ or UMTS unless you have a custom rom or modified notification icon...but near my house about a month ago it kept switching back and forth that means it was switching between 3g and 4g...although it will show 4g no matter if its HSDPA of UMTS...I complained to tmobile about my connections speed and after about month they said they were working in my area and my speeds are amazing now and battery life is much better...here's and app to tell what you are on and the signal strength...
https://market.android.com/details?...51bGwsMSwxLDEsImNvbS5pbmRlcGljby5uZXRzdGF0Il0.
also put your screen on auto, and DO NOT use a task killer makes things worse...Connect to wifi whenever you can, weak wifi can also cause battery drainage...This is true of all phones on the market with 4g today...my moms my touch 4g used to get about 5 hours of battery, and she HAS NO INTERNET ON HER PLAN...SO I SWITCHED HER phone over to stickly 2g since she will never really need 4g...now she gets about 20 hours of battery time....4g is just a battery killer no matter what phone you're using...
So how about the battery in the Lumia 920.
After the Lumia 800 failed in this area it would be great to know if the 2000mA battery is big enough for this whole Thing

I've been using it for half a week now and battery is phenomenal even in LTE all the time. Will last you a full day off not a day and a half with moderate use. Full day heavy use probably.
You have nothing to worry about this time. Nokia got it right.
More details here: http://forums.wpcentral.com/showthread.php?t=200158
Mine sucks right now. I'm just using it for normal email updates and a few downloads from the app store and it'll be on 40% by 4-5pm. I've turned off a lot of the background updates on the live tiles too, but it's not making a difference.
Screen on time is disappointing.
Mine has excellent battery life. 2 days on a row on my last charge.
Ppl with battery life problems, I would suggest to visit the Nokia support forum.
Important
If you disable NFC (tap+send in settings) you have a HUGE improvement in battery life.
As mentioned above, disabling NFC and background apps will greatly improve battery life. I am more than satisfied.
I leave my data connection on 2G most of the day and it seems make the phone last all day, with heavy use. If I really need the faster connection I switch it to 3G. This seems to work for me
Full day, 3G use (using on a 3G only carrier, no LTE unfortunately). Moderate-to-heavy usage, not a problem getting back home, chilling on the sofa, doing what not, and having enough battery to last until bed time. FYI my day starts around 8-9 and I head to bed around 11ish+.
I hear battery life isn't as good when NFC is on. Don't know though, I never have NFC on anyways (really don't see how useful it is atm).
Battery saving Tips
This battery saving tip has been overlooked since WP7 first generation devices. The reason why some ppl will be having huge battery drain is due to apps running in the background. So, you need to think about the apps that you actually need to run in the background. Make sure all your email accounts are on the highest interval time to be checked and/or "as the item arrives". When you select as the item arrives I believe true push is being used which if you don't receive tons of emails will save battery in the end. The other apps settings are located here start screen>settings>swipe over to applications>background tasks>and block all apps that you can that don't need to be running background tasks. I for instance only have accuWeather app running background tasks. Another thing is you need to be aware of apps power usage...i noticed that accuWeather is far better at using less power consumption than the Weather channel app. Other tips are common knowledge. Disable NFC, use WIFI when available, turn off high sensitivity if you're not needing it, use low time-out for shutting off display and use low brightness. Be efficient!!
Good
Lasts me about 1hr for each 10% increment. About the same i was getting with the S3. While playing music its battery life seems to last longer than leaving it on standby :S Find standby kills battery some reason, just recently turned of nokia drive background app, hopefully that makes it last longer
Battery life has been excellent for me. Mine was fully charged on Wednesday morning @ 8 AM and was at 48% when I put it on the charger Thursday @ 2 PM with moderate uses. Unexpectedly, the battery life is much better while on the LTE network than when I'm using my SIM card not registered for LTE usage. Standby drain is very very good.

That's because WiFi stays connected when you're streaming music, whereas WiFi disconnects when on standby. Known windows issue that should be addressed by ms soon.

I get great battery life unless I enter into an LTE area. When I do, my phone gets VERY hot and the battery runs down in a few hours. Even if I'm not doing ANYTHING with the phone. Strange...

How do you switch the 920 to 2g mode? I only have 3g and 4g in the options on max speed? my old lg wp let me set either 2g or 3g, huge difference in battery life on that devic.
to be honest tho so far i'm impressed easily outlasts my old phone, just tried turning off the high sensitivity on the touch to see if it makes a difference.
also run down the phone till it turned itself off last night, tried turning it on got the warning icon of low battery, did it again then it started, data connectino wouldn't work battery said 0% remaining and it lasted just under half hour with me playing mirrors edge, makes me wonder how accurate the battery % is
Battery capacity seems to have been cut in half!
When I first got the 920, at 100% the estimated battery life would say 1 day and X hours. Now (2 weeks later) when my battery is at 100%, it now says 13-14 hours of estimated life. My battery also drains much faster now than it did in the first week of owning the 920. My use of the phone has not changed over the last two weeks. I'm always in an LTE area, WiFi on and I use bluetooth from time to time. Is this an issue that other people are experiencing?
I'm trying to figure out if I need to exchange my 920. Any help or advice is much appreciated. Thanks!
i found it was using 2% battery every hour whilst connected to a data connection - but not syncing anything, all backround tasks turned off. This seems a bit mental.
So it seems that battery isn't so good :/ Too bad because i was wondering to buy this phone.

After deep cycling the battery, I am back to the correct reading. I am now losing a little less than 1% of battery life per hour on standby!
When you sleep, does your phone sleep, or does it stay up all night and crunch 1s and 0s? Rate this thread to express how you deem the speed at which the Moto Z's battery drains under standby conditions. A higher rating indicates that when the phone is not in use, the battery drains minimally.
Then, drop a comment if you have anything to add!
Pretty good
Lost 3% on standby during 8 hours through the night.
Now that I'm on nougat, I'm losing about 8% over a 7 hour period
Not all cores stay in deep sleep when the screen is off.
I am seeing about 50% at 652MHz and 50% Deep Sleep when the screen off. I am not sure if this is expected.
I am also losing about 1% / hour in standby with the latest Nougat Update.
I just got it so I can't compare before & after.
1 percent per hour can be completely normal depending on someone's setup, apps install, signal strength, etc.
Most phones I've ever owned are about that or just under. Only my Nexus 7 2012 was way lower. About 0.4% per hour.
1 percent per hour is definitely not anything to be too concerned with honestly.
I'd start with CPU spy or a similar app, to see if your phone is actually in deep sleep when not used. If not, then you could have an issue.
i am extremely satisfied with stock(everything stock unrooted,locked bl) standby drain. I don't use Approach, Attentive Display and Notification Display in Moto app.
Wifi ON : 3% over 7 hours sleep
Wifi OFF : 1% over 6 hours sleep
Data(3G) ON : 7% over 5 hours sleep
Since N7 update, getting very bad idle drain.
Losing 28% during 7 Hrs overnight (>4%/Hr) and the BBS logs don't show any major issues.
Posting my logs here hoping a fresh pair of eyes can locate any anomalies I missed.
You might have bad reception in the place you have your phone. Check settings>battery> click on graph>cellular network signal. If the bar is red/ orange or has many small red lines you might be located between two towers.
Try switching to 3G or 2G overnight and if there is a dramatic difference it will confirm its signal-related battery drain.

Just an update; I used a Tasker profile to disable WiFi and Bluetooth when Display is off between 11 PM to 6 AM (my approx. sleep window). This has brought down the Idle consumption during night to 0.8%/Hr suggesting at-least one of them to be the reason for abnormal drain. I think the WiFi or Bluetooth modules in the Nougat update may not be fully optimised. I intend to test with only one of them turned OFF alternatively over next two nights and locate the real culprit.
Of course this does not help me during the day when both WiFi and Bluetooth have to be kept ON as I can't be bothered to turn them On/Off frequently whenever I start/stop listening to music or connect/disconnect to work WiFi. I'll explore if I can write Tasker profiles to switch them On/Off based on location, proximity to work WiFi AP and music steaming status.
Also, as suggested by @Vcek above, I can see some orange bars in the battery graph overnight indicating signal issues at my home location which may also be adding to the increased drain.
Overall I am sufficiently comfortable now knowing what is causing the increased drain and having at least some level of control over it.
My phone still open when i asleep .
Hmm..
I've been thinking about this as well in the first week of owning the phone. I leave out at 530am and get back around 6pm and am sitting around 50% (not bad, don't get me wrong). But the 2 year old phone it replaced would still be at ~40% in the same day.
It's better, don't get me wrong, just not as much as I figured.
I have had the Pixel 6 for a week now and I'm very disappointed. My biggest disappointment is by far the battery life. I can barely get through an 8 hour work day before it dies (Note: this is with zero WiFi use). After 8hrs I'm typically at 10-20% battery or dead. The mobile network standby is slaughtering my battery life. It uses a consistent 25-35% of it everyday. I also seem to have a lot of weird bugs.
-I get occasional system UI crashes
-randomly I'll lose signal where I always have signal and have to turn it off and back on or reboot
-auto rotate I have to frequently shake my phone for it to work
-camera quality seems terrible. My photos are almost always blurry. My OnePlus 7 Pro takes much better pics.
Update: The 8hrs is total battery life not SOT. My SOT is like 3-4hrs average sometimes worse. My phone use also stays in a 6ft area all day. So I'm not like in and out of service. I also make no calls during the day.
Update 2: I've had 5G disabled all day and I've had 3.5hrs SOT and have 45% battery left and it's the end of my work day. I'm happy with that number. Still having weird OS issues like system UI crashes, Spotify pausing randomly and it not working with the Google assistant. So I think I still need to do a factory reset unfortunately.
I am returning it also tomorrow.
I already did factory reset without any result.
Mobile network standby is killing the battery.
30% day and 60% overnight.
I tried everything without success.
Fingerprint Scanner also is terrible.
Bump.
I had big hopes for this phone.
Try clearing system cache.
Try a network reset.
Try safe mode to rule out 3rd party apps.
Try turning off any power management.
Use factory reset for; you did a major firmware update, for malware, damage to hidden users settings by a 3rd party app.
Otherwise the issues are likely to reoccur.
Try to find the root cause(s). Cloud apps can use a lot of power day and night. Trash apps like WhatsApp, FB, etc waste power and abuse privacy.

Damn, what carrier did you buy it from? I'm also disappointed in the performance of the finger print scanner. I was expecting that though and it works if you hold it. So that's not like a deal breaker but all the reviews I watched before purchasing were saying great things about the battery life. Google even advertises it as a 24hr battery life. Which I don't expect but I need to at least get to when I go to bed without charging.

I am using o2 Deutschland.
Tried different carrier also.
Tried esim and physical card also.
Tried every combo on network preferences.
Mobile standby mode is not dropping below 25%.

I'm using 5G and will try doing that next. I don't really need the 5G speeds but I like seeing the icon lol.
Just got another system UI crash
Disabling 5G seems to have actually made my battery life worse. My phone is at 12% after only 8hrs of use..... Usually it's at like 20% after 8hrs.
So on WiFi my battery is amazing. In the past 3hrs with high brightness and over and hour of video and the rest on apps it's only gone down 6% So if the network standby issue can be fixed my battery life would be great.

Is it a joke ? Have 8hr SOT and crying ?!
Don't read too much into the two-hour "battery usage" percentages. They don't have any relationship to how much total energy was used - they only show the relationship to other tasks running during that two hour period.
For example, we can assume that the "Mobile Network Standby" power usage is pretty consistent if you remain in the same physical location and make the same amount of cell phone calls/texts. However the bi-hourly use % will be wildly different depending on how the phone was being used. For example, you are showing 66% Mobile Network Standby when the phone is sitting idle and not being used. That is to be expected because the phone was literally not used at all so there are very few tasks using energy during that period of time. If you compare another time when the phone was being used, the Mobile Network Standby might only account for 22% of battery use during a 2 hour period. The actual energy used for Mobile Network Standby was the same in both cases, but the % changes depending on what other tasks were using energy. It doesn't mean that it used three times the energy when it shows 66% vs when it shows 22%.
You can see this same type of battery usage detail for the last 24 hours by clicking the drop down menu "System usage for past 24 hours" on the initial battery usage screen. This will show a more accurate accounting of how much actual power each app and system process used in the last 24 hours. Unfortunately it is only for 24 hours and not since the last full charge, so it can still be a skewed number because it still doesn't show how much battery power was used, but only what % of total battery use each item accounted for. In other words, you could charge and totally drain the phone 3 times in a day, and the percentages would still look relatively the same vs someone that didn't charge at all during the day.
I suspect you will see your Mobile Network Standby number run about 20-30% when you look at this number.
Plus, your first set of battery use images show the phone using about 55% during an 8 hour period. The second set of images show the phone using about 75% over a 12 hour period. Of course we don't really know what type of use you really had during those times, but that isn't terrible. That shows the phone should last about 16 hours based on your usage.
You are also showing about a 10% decrease in battery life when the phone is setting idle for 8 hours. Honestly this is about normal battery life and you shouldn't complain about it. These phone are going to use a little more than 1% total battery power per hour when they are sitting idle and on cellular (not wifi only). If you are seeing 2-3% battery use per hour while idle, then you should be more concerned.
I have 11h40 SOT with the Pixel 6 and it is more than enough for me.
I loose 8.2%/h with the screen on and 2.7% with the screen off

This is from 93%.
I am taking in best case 4 hours sot.
All the other battery is drained by mobile standby.
I am loosing sometimes 4% with screen of and wifi turned on, when my old redmi note 10 pro loses 0%
I guess i get faulty phone.
But i am done with with pixels.
