My battery life seems far too short. If I remove my phone from charge at 6am it's got very little life left by 10pm. 16 hours is pretty poor... No WiFi or BT, but I do have reasonably high usage of around 15-20% perhaps.
I did read something about Quick Calendar being a bit of a drain, but I really like this widget, so I don't really want to lose it.
I don't have all that many apps installed, maybe 10-15. How does this battery life compare to everyone elses? Is there anything I can do to extend it?
mine last about the same. I am using the internet alot & widgets like twitter & flickr as well as watching films/listening to music. To be honest I think that this battery is pretty good seeing as how much I use.
When I compare this to my Diamond which i was using a lil bit less by way of features I am truly impressed with the stamina they have given to the stock battery.
That being said if they ever release an extended battery I will be buying that in a heart beat
Generally I think it has decent battery life, but its changeable. Sometimes I wake up in the morning and the battery has drained overnight from nearly full to totally empty, but sometimes there is no indicated overnight drain based on the battery meter.
I think the battery meter is probably about as accurate as the one on my Diamond (ie not accurate at all)! I get the same battery life from my Hero if not more as I did on my Diamond with the extended battery which considering I do a lot more with my Hero is impressive.
I think the battery is pretty good considering all it's doing.
When I have it on, playing mp3s and HSDPA and wifi all day, I'm lucky to get 12 hours. I mean literally MP3s all day though, and since I'm at work having a usb cable into my laptop isn't a big problem, which removes the battery problem.
Today I've had limited internet use (mostly just 2g email polling, with about 30 minutes of whatever 3g exists in the bowels of wiltshire) and, as I've just noticed about 3 hours of GPS. It says it's used about a quarter of it's battery. Used as a simple phone, I'm sure it would last more than 3 days, but why bother?. As a pure email device, maybe just under 2, and as an always racing internet/music/gps beasty 1 day.
I'm happy with it.
Have you tried intstalling taskiller to get rid of those apps using power in the background?
My battery life is terrible. I fully charged my hero and unpluged it 8 hours ago. Since then i've made 10 minutes of calls, around 45 minutes of browsing (with 15 minutes using wifi), and 'played' about with it for around 30 minutes. My battery is down to 20%. I don't think this is good at all because i haven't used it that much.
edit: I also use taskiller to close apps after im finished with them.
Yeah, I use taskiller, nice app. I've also installed something called Power Manager v1.5.9 but I'm not really sure how it helps... if it does...
Woah I started doing a Battery Saving /Speed up Tips thread last night - Just posted it - Any good stuff post on there... Plus there might be stuff you've not done yet (Tho its pretty straightforward stuff that I reckon you'll have done already Ya never know tho)

I found the first 3 charges only gave me a day (but this was when hammering the phone for the first few days), after the 4th charge and dropping to my normal useage i get 2 - 3 days, which is just better than my Tytn2.
I use my hero as my works phone and make about 40 minutes of phone calls on a 12 hour shift, it also picks up my emails and does about 30 minutes of browsing during that time, and by the time i get home it has about 30% of battery left which isn't too bad, and is much better than my diamond.
Things seem to be improving for me too now. Also, I took of Quick Calendar which people were suggesting was eating battery...
The first week I had my 920 I was lucky if the battery was at or above 40% by 12 noon. The 920 is my 2nd phone line and I am using it mostly to learn WP8, to surf the web some and listen to a lot of podcasts, usually 6+ hours of them a day. The past 4 days the battery in the 920 is showing insane runtimes. It is currently 11:30pm and it has been off the charger since 8:00am, over 15 hours with overs 8 hours of audio podcast listening. The battery is currently reading 61%. I originally got the impression that LTE was killing the battery, but that is no longer the case.
I have a Share Plan with AT&T with 2 phones, a Galaxy Nexus (GSM model from Play Store) and a Lumia 920. I use my Nexus as my main phone line, to access GMail and Google Reader (a lot of Google Reader feeds). The Nexus has been off the charger the same period of time and is showing 41%.
For me wifi destroys my battery for some reason I get 15 hours with wi-fi on or 28 with it off
Interesting, mine will usually run for 24-30 hours before hitting 15%, including regular usage. 4G gives it a whack but generally I find similar to other phones, if low coverage it chews the battery
Reading all the doom and gloom of 4G LTE on various mobile phones, after my 1st weeks experience, I was expecting similar results going forward. But, after 2 weeks of use, the battery falls in line with the results you mention. And, with that I am not complaining.
same situation here.
It looks like the phone needs some days to warm up and get long lasting.
Also I see that wp8 is heavly optimized for background task in order to not consume a lot of battery eg: my phone lasts more than 2 days with light usage.
I listen to podcast for many hours and it doesnt affect the battery that much, in fact I'm surprised by it because I know audio playing takes a load on the cpu.
Mine.. overnight without charge or using the phone it drained from 100% down to 35%. BS
Two words: Background tasks.
Make sure you don't have unnecessary background tasks running. I have less than 5 and my battery runs more than 2 days easily.
How do you kill or monitor background tasks?
I had really good battery time of 19 hours the first day of installing the new firmware, then I enabled bluetooth again and it drains like crazy. its hit or miss but people seem to think that whatsapp drains battery. I personally would like to disable LTE (its really slow in my area) and just keep bluetooth that seems to give me 12+ hrs of battery.

You can block background tasks for 3rd party apps in Settings->Applications tab->Background tasks. There is no way to monitor these tasks because WP OS doesn't offer any such capability.
Unfortunately there is no easy way to block 1st party apps and if they are misbehaving (like sync something over and over), there is nothing you can do about it.
Turn on Battery Saver can also effectively kill all background tasks. But that's draconian. I still would like my smartphone do something in the background for me.
Don't forget, the biggest battery drain factor could be your cell phone signal. If you keep the phone in a fringe area, the cell radio will drain your battery very quickly while try to maintain communications with cell towers. This is outside the OS and you can't do anything about it.
I had a weird battery drain the day after the last upgrade. No apps running in the background BAR the movie that i had paused.. I lost 80% without using the phone in a 6 hour period (post charging). After a reboot it seems ok. Perhaps i should pause another movie to see if it happens again....
I must say that I have mine 2 days and the battery drains too fast... I dont know what to do .. Maybe because its new ? Some one can help me maybe ?

don't judge a phone's battery life until a week later.

My battery is pretty inconsistent. MOST of the time it's awesome, and will last like 20-25 hours without needing to charge, but that just makes it especially jarring when every now and then I go to check my phone at 4 in the afternoon and it's at critical, and I have no idea what causes it.
Plus when it does die I have to put it on the charger for like 2 hours before it will let me turn it on.
I found interesting point in the battery life today, if the screen is off, the battery drain is in the range of 3-4% which is good, however, if the screen goes on the battery drops like 15% in just 25 minutes. After thinking I tried to set the screen sensitivity to normal and it solved my problem. I kept the screen on for more than 45 minutes and the battery went down almost 6% only which is good. I still have to test more to give a concrete evidence.

I usually run a battery discharge app Saturday night. Then a full recharge with the phone off. That usually gives me dependable battery life of about 12 hours a day for the entire week. If I forget and not run the discharger I notice it midways into the week when I only get about 8 hours out of it.
AT&T lumia920:
after updating my phone to the 1314 update, my battery life got worse.
I went from 14 hours per day to only 8 hours.
thanks nokia -_-
note: I was not experiencing any connectivity issues on my phone.
let's see how many people here actually have NFC on and Auto-Brightness on... lol
I used the sleep app last night after charging to 100%, and then I fell asleep with it on.
I woke up to find the sounds still going, and when I checked my phone worried that I killed the charge, I found it still had 92% left. That's impressive.
Hi Everyone,
I'm just wondering if I have an issue or not. I've already went through one G5 which was severely overheating and was giving me less than 2 hours of screen on time within the first week. I'm on my second G5 now and have had it a little over a week, but the screen on time seems to be dropping drastically. When I first got it, I have a SOT of 5+ hours. Then it got progressively worse until yesterday it barely made it to 3 hours and today it was under 3 hours. I'm a fairly heavy user, but it seems like I can literally watch the battery percentage tick by when I have the screen on. In fact, it seems like it's markedly worse when the battery is under 50%. For example, today at 50% I had a SOT of about 2 hours 15 minutes, and then for the last 50% it was like 45 minutes TOPS before it was drained. My standby time is absolutely amazing, with it losing less that 1% in five hours.
I just don't know what to do. I have 5 more days before I can exchange it no questions asked. I just see some people with 7+ hours SOT and it seems like mine is heading in the opposite direction.
Cheers,
Bloody
3-4hrs of SOT is average/normal
3 hours of SOT is on par, or very slightly subpar, with other users. Some, like me, get a bit more, but just because i do not use Facebook, or games. You should consider which apps you are using, if there's something always on and in "Sync" it's gonna eat up the battery a bit more. If you game a lot, same. That said, this is not a huge battery, but it should be big enough to get to bed. Can i suggest maybe (i know its obvious...but!) cleaning up the recent apps, taking more care in switching on and off the wifi...this kind of things could get you 30+min more in a day which could be enough to get trough the night.
To answer your question, you probably have not a defective unit. If this SOT time is not even close to what you need, the brightness of the screen poses a big problem for you, and you don't care as much for the awesome camera compartment, or the swappable battery, and you dont hate touchwiz, and you can return it no question asked, the s7edge has better battery time, and higher brightness and saturation.
I average 3 hr SOT. It's normal. Total 13.75 hours on average with 5.5 hrs active.
With the brightness about 30%, I could have about 4 to 5 hours browsing web with wifi...
I'm really impressed by the battery on the A7. I've had 3.5 hours of sot and 20% left even after caning it with DS Audio, 4 hours of internet radio, 50 photos plus editing and lots of surfing.
Doze is extraordinary. Check out last night's battery consumption (I really must get to bed earlier).
Best battery life on a phone that I've had so far.....Well, since smartphones. I had some flip phones that could last a week.
It seems to be a bit better than the Nexus 6P I came from. Definitely not as good as the Oneplus One, much better than the Moto X Pure.

The main thing I've noticed is that this phone doesn't get excessively hot which seems to kill the battery very fast (both issues I've had with almost every smartphone owned: Nexus 6p and Oneplus One included). Apps that use GPS, camera use, gaming etc don't seem to get the phone as hot and this seems to correlate with better battery life under use. The only time I feel the phone warming up is if I'm using the Quickcharge charger while doing something else. It's barely warm though.
If I babied my Oneplus One (Sultans ROM) I managed to get 8 hours SOT which was crazy but it didn't charge the way the Axon 7 does and it certainly wouldn't have coped with the stress I'm putting on the Axon 7. I remember things like constant GPS + Spotify + Bluetooth would mean my Oneplus One wouldn't be able to charge as fast as the battery was being drawn. Not an issue at all with the Axon 7.

I agree on all points. This is one of the coolest running phones I've ever used. Only thing I've done that creates noticeable heat other than charging is +30 minute phone calls on Bluetooth in car. And it charges unbelievably fast. Very happy!
Got ,5 and a half hours yesterday. I honestly average 5 hours. Battery life has improved significantly with this smart power voodoo on. It doesn't affect performance unlike it does on tw.
I notice more apps are closed in background when I have smart power on.. Like I'll be able to have about 5-10 apps open with smart power on.. But 15-25 with it off.
I get an extra hour sot with smart power on.
And I took quite a few pictures that day.. Totally thought I was going to toast my battery.. But it held up better than any of my samsung devices..
The Axon ZTE 7 A2017 has the most smart power!!! I dont have to worry for the whole day charging my Monster!!!
I agree with all the comments here the battery is really good, pair with fast charging if necessary is a winner !!!!
Same here I'm enjoying the battery life on this bad boy!
I would also say it's not too bad.. still 25% remaining after 5h DOT
Agree! On at 6:30 am and still at 86% - light use. 1 phone call, a few texts and 10 or so minutes checking the news. My note would have been 70-75% by midday with about the same use. Power save mode on both phones. Very happy with this phone.
I started this thread and I'm still pretty happy with the battery life but this evening I noticed the phone was a bit hot. First time I've noticed that. It drained from 45% to shutdown in 10 minutes. This is what my Oneplus One used to do. How can the same sh*t happen to the same guy twice?

Sounds like you've got a rogue app in three background that's forcing your CPU to max out and keeping it there even when not in use. There were a couple kernels on the oneplus one (including stock) with bugs like that, but it's not a kernel issue with the axon because otherwise others would have seen this. I'm betting it's a bad app.
I had just installed Kayak. Battery back up now. I'll see if I can reproduce the issue.
I cannot see the usage of apps. Any solution? I also can't see it in the system battery settings.
My buddy has this phone and literally flawless. i mean it works. it lasts. its powerful. has amazing SQ. and im over here with a friggin note 7 barely squeezing 16 hours out of it with3-4 hours DOT/SOT.
Not to mention XDA and everyone gets it wrong. its a 3250mah battery not a 3140mah

I use spotify or pandora via BT. we drove the same distance. same time etc. i lost 17% he lost 5%. both were fresh rebooted and waited 10 minutes. closed all apps and screen NOT in use. no wifi no nfc no nothing.
Can't wait for the battery life to further improve with android 7.1 and maybe even eventually a custom kernel
I'm getting minimum 6hrs of screen on time and i'm very satosfied with this performance
Hello.I use this masterpiece about a year now with really heavy usage.I almost charge it every day,or about 5 times a week the less..In the first 10 months with KITKAT i had always about 10-11 SOT hours.After 10th month also with kitkat,SOT reduced to 9-10 hours.At this point i updated to lollipop cause a certain mod that wasnt supported from kitkat.The SOT about 1 month remained same as kitkat.And finally the last month i notice that SOT has reduced to 7-8 hours.Also to mention that after 8th month the battery has veeery sudden drop from 16 to 8%.It drains about 1%/minute!From 8% and bellow it drains much more smoothly compared to 16%—8%,but not as smooth as 100%—16%.Is there any way to calibrate battery or to find out if is battery issue?
Thanks for possible help.

For starters, if there was a 8 hour reduction in SOT in the course of a month, something must have happened. Either the way the device is being used, or the apps you are running. No two ways around it. Also, if it drops 1% every minute your battery has either become defect (dropped the device lately?) or again, something is draining it.
There are apps you can download to check what drains the battery and hog memory etc. Don't know their names, so Google it. Otherwise, I would do a back up and then do a factory wipe. Test the factory wipe for a day or two without restoring and check if the battery drain remains the same. If not, there is indeed something you are running that is causing it.
Lastly, our Li-Ion batteries lose their capacity over time. SOT will significantly reduce over 15 months or so, depending on usage maybe earlier. If I leave my screen off the entire day I lose around 15- 20%, if I use it I get maybe 4 to 5 hours playing games with my Bluetooth headset connected and WiFi/LTE. If I watch movies it's a bit less. Just how it is.
thanks dude.i loose 1% only between 16%-8% very weird..no i never dropped it and i notice that battery drops the same way either when is just formatted or not..if i leave it allday with screen off i loose just about 2%...
