Battery Stats Thread

So I was wondering if anyone who has their device already could post some screenshots of their battery usage, screen time etc?
I know there have been some thrown around numerous thread but just thought it would be useful if people would post in one place?
Thanks

just wanna share some battery life stats..
1st power up of the phone.. did a full charge with phone off, once charging light changed to green, i powered up the phone.. 1st thing i notice.. it is not fully charged to 100%..
next thing to take note, the entire duration the phone is on is an additional hr plus.. i rebooted the phone once so im not sure what is the actual duration the phone is powered by the battery..
all in all, about 3hr+ with high usage of the phone.. notice how the phone was awake most of the time and the screen was on most of the time too..
cheers..

Only if this phone had some decent battery packed in, as in the Note, I'd have grabbed it. Why HTC why ?

Screenshots ain't working.

Is it true that there was yesterday a OTA to fix battery issues?!?! If yes, did it solve? and what is the version number?

These are my stats from first day...not bad given how much I'm played with it

Whats your screen on time?

1st post so I hope it's helpful.
I'm a big fan of the phone & love it, there are a few small issues I've noticed & I'll post these in the relevant thread.
People keep saying the battery life is dreadful but it doesn't seem much worse than my original Desire on similar use.
After the first full charge last night I plugged in the charger when the warning came on at 9%:
11 hours 2 minutes on battery, screen used 75% of the power while on for 4 hours 31 minutes.
Everything else used a few % each.
Brightness was on auto at approx 50% most of the time and on full for about half an hour; indoors I wouldn't want it as bright as that.
F/W 1.26.401.2

The battery you have seems to have lasted better than a few others who have posted here.
Was it heavy use or normal??
Thanks

Hi
Thinking about this phone or the one s. Just a quick q regarding the documented poor battery. Could i go out for the day - say for 15/16 hours send the occasional texts maybe a couple of photos/videos and the occasionally browsing the web - to check football scores etc etc.. should this handle that ok ?
is a pocket charger the way to go ?

That's how I intend to use the phone tomorrow, so i'll soon let you know.
The thing with this phone that is superb, there is hardly any drain when your not using it. It's extremely good for idle power saving.

dunno about you guys but i'm getting insane numbers in standby...
overnight i lose 1% with wifi, data and autos-sync on....
it's the first android phone that sleeps properly when screen is off...there's nothing keeping it awake.
i'm on 1.26 by the way

Well I don't think it's that bad on battery given how much screen time i've had....three and a half hours.
Only got 2% left so going to put it back on charge. These are my final stats for my first day after a 13hour charge

I'd say your battery life is pretty poor.

My battery is a little bit better. I don't have any screen shots right now, but it's usually around 3 - 3.5 hours on screen. Around 7-8 hours battery usage total.

Try downloading Gsam or watchdog from the playstore. Watchdog will tell you if there's a rogue app draining your battery and Gsam will tell you what's taking up the most power.

let your phone do a 3-4 recharge discharge cycles..then it would stabilize.

what is a recharge discharge?

charge it to 100% then let it discharge(1 cycle of rechrge of discharge) although there maybe a better word to represent that(noob in complex english )..

With 2 hours screen on time over an 8 hour period and your steady curve on that graph, I would say you have some app, or some service eating CPU cycles constantly (these are called wake locks)...
Do this:
Download an app called CPU spy
Charge your device all the way
Pull it off charger
Open CPU spy
Then just hit the back button to close it.
Let your device sit for about a half hour. Don't touch it as much as possible. Leave the screen off.
Open CPU spy... post a picture of what your CPU stats say according to that app. Majority of your times should be in deep sleep mode.
Also, your battery shouldn't drain anymore than 1 to 1.5% each hour at idle. Unless you live in an area where there is poor reception (scanning for signal chews it up as well).
EDIT** ALSO...is your screen brightness on auto or is it manually adjusted a little brighter? If it on auto, then your battery life according to those graphs is absolutely awful. I have mine set pretty bright and I still see about 3 hours of screen on time

Give it a few hours of "normal" use and then come back here with a Betterbatterystats screen shot with Partial Wakelocks/Since Unplugged and Processes/Since Unplugged. That way we can see what is eating your battery. With only 4% gone, we can't see anything (too small of a window). Make sure you don't plug it in and use normally.
I have seen your other posts and I am wondering what it is that you really want out of your battery. If you think that you can get 3-4 days out of a charge, that is not going to happen. 1.5-2 days is a reasonable expectation and I think that you can get that, but you have to look at your usage habits. No kernel is going to fix that. No ROM is either.
If you are polling notifications (Facebook, G+. Twitter) or Google Locations (Maps, some app that requires location) or believe it or not using the XDA/Tapatalk app a bunch, then those will drain your battery quite fast. I use the Tapatalk app quite a bit and that and Google Now are my #1/2 battery drainers. Could I get rid of Google Now? Sure. It is more of a novelty at this point. I still get 1 -2 days of charge on my phone wihtout worrying about where a plug is.
Like I said, come back at the end of the day or tomorrow morning and post the Partial Wakelocks/Since Unplugged and Processes/Since Unplugged and we'll see what is draining your battery.

Another thing to note is that it seems your mobile network is typically pretty patchy. This can really drain your battery too.
I've been chasing wakelocks since I got my device and think I'm at a pretty good place. I get 2.5-3hrs of screen on time (about 20% screen brightness) across about 25hrs of standby time. Does anyone else get a lot of mmc1_detect and mmc0_detect wakelocks?

thanks woodrube. I will post my stats at the end of the day. I don't have a facebook or google + or any app that have notifications or updates by itself. I have the screen set to 20% brightness

how do I delete that dmux wake lock?

[Q] Slowly Decreasing Battery Life

I updated to 4.1.2 about 3 weeks ago or so. Not sure exactly. And the battery seemed to be just fine then. But slowly over these weeks, especially the last 4 days or so, it seems to be decreasing. I used to be able to go a whole day easy. And still have 45-50% left. And that would continue into the next day. Sometimes I would get 2 whole days and sitll have about 15% and then decide to charge it back.
Now, I can barely get a full day. And when I don't charge the phone at night, the battery charge decreases quite rapidly. Sometimes 15% or so with no usage at all overnight. It used to maybe move 3% at the most overnight with no usage.
My settings are the same. My usage is the same. I see time without signal is 2%. Nothing extremely high there.
Is this just one of the downside of 4.1.2 or is there something else happening that I'm not picking up on?
I didn't want this to really turn into what apps are out there to make the life better because I hate jumping through all those hoops and settings to get the most. I know this phone has the potential for 2 days of moderate use out the box because that is what I used to get. Seeing if I could get back to that state.
I was told to go into Wifi settings and change the setting not stay on while the phone is sleeping. Did not help at all. Per this video:
http://www.youtube.com/watch?v=mInF-ZRX5bs
Did that last night. Charged it 97% and went to sleep. Slept for 5 and a half hours. Did not touch the phone at all. Woke up and it's at 82% this morning. Here's the screenshot of the battery stats:

Glad it's not just me then. Have you found anyway to make it a little better?

Well if you don't need to wanted at night, then what I do is put it in airplane mode and take off when waking up.
If you still get wake locks, check to see which ones they are off a wake lock app.
Also before I put into stand by, I exit all apps, also restart phone with airplane mode on. Doing this I haven't lost any battery life at all and seems to help throughout the day as well
Currently 60% right now and over 3 hours on-screen time and 16 hours.
Doing much better if I don't do what I have been doing.
Also make sure all GPS location settings are off. Huge battery drain for me.

Yeah I know airplane mode will work but I receive texts late at night sometimes and those would not come through. Before this update, I never had a problem. I never had to make sure apps were closed and all this other stuff. It just never drained on me at all. When I first had the phone, I used to have to try very hard to drain the battery to zero so I could let the phone die and then get a full charge. The battery life used to be very great. Now, not so much.
And I have no idea why Slacker is being used like that. I haven't used that app in 3 weeks. And I don't see any settings that would cause it to being used in the background when I'm clearly not using it.
Yes I never have GPS on until I need it for navigation purposes. I'm hoping Key Lime Pie fixes this or we get another minor update before that.

You should never discharge your phone to anywhere close to dead. It ruins your battery

Do you have lte on? Are you in an lte area? Have you tried a factory reset?
My battery life was horrible when j first upgraded. Seeing as i am not with T-Mobile i do not get lte. I turned my lte off and my battery went back to normal.
A factory reset may also clear any gremlins that you may have left over frlm the update

Same here owned it since december...great battery and after update it went down the drain (especially losing 15-20% overnight with just about everything turned off. I would usually let it get down to 10-15% and then charge. Well eventually my phone would only charge "when it wanted too" so I got a replacement, updated to 4.1.2 and battery lifes has been great.
As far as not doing full cycles or not...ive looked and looked and everyone says diff. Some experts argue it's good to let ot drain till about 5% and then charge And other experts say charge often and not let it below x percentage. Soooo confused on the topic, so in the end to each their own I guess lol

well, if you're not using the phone, with apps or whatever.. then something else has to take the place of the 'most used' application..
I hope this isn't the "omg android system is using all my battery" again that I seen all over the gs2 forums when it came out
attached is a screenshot of my battery usage, I been streaming music all day at work.. mostly wifi, screen on a generous amount of time.. browsing xda, internet.. even played around with autodesk sketchbook..

Just got the phone today, it's been ridiculous. I've recharged my phone from 20% to 95% twice today. Granted, I've been using it non-stop
Now at 65%. Just terrible!
Android System 38%
Screen 20% (time on only 2h 5m)
Android OS 11%
Facebook 8%
Cell standby 5%
I had a lot of sync crap turned on that wasn't on my note 3 (like auto sync photos to google cloud), as well as some other settings that I just turned off like AT&T Address Book, and several google sync services I have no need for. Hoping that fixes it, I'll know tomorrow!
Android System.. that is where it would be syncing photos, right? I'm thinking that must've been it.

A background process is eating your battery. I have gotten over a full days use with 3 hours or more of screen time and still at 35%, that or you got a bad battery. This phones battery life is incredible

Since I just got my phone this morning, I will have to report my batter usage later.
However, the phone charges SUPER FAST!

I'll tell you when it doesn't charge fast, I plugged it into my S3 charger last night at 11% and it still wasn't at 100% when I woke up about 9 hours later. Yesterday I got 3 1/2 hours of screen time after starting at 70% when I actually got the phone around 5 pm. The phone was under HEAVY use (downloading updates on LTE, customizing, etc.) I'll be interested to see how it does today under mostly normal conditions.

Glad to hear you feel that way! Thank you for the glimmer of hope! I have a feeling you are very right, and that it could have also had a lot to do with the huge amount of downloading I was doing yesterday. Today should be a much more normal day of use. I'll check back in a bit.

My battery went from fully charged to 94% in a matter of minutes just using the Internet. I decreased the screen brightness and removed the sync from some apps. If I don't see an improvement before my 14 days is up this is going back.

I also realized power saving mode was not enabled. After enabling that and disabling all unnecessary sync services, I'm stoked.
Usage seems to be great now, too.
81% battery left so far today
1h30min screen on time
3h23min total
Screen 33%
Android Sys 21%
Android OS 13%
Stellar!

You shouldn't have to use power save to get good battery performance. You definitely have a bad battery

Really? It seems pretty good to me now.
Is there a wake lock detector you would be able to recommend? Looks like it needs root?

I let my battery completely drain where it cut off at 1% and let the battery charge fully. Powered it back up and made sure nothing was syncing that I didn't need and now the battery seems to be performing better then before.

Was on web and Facebook most of the time, downloaded some new apps, and uploaded a video to vimeo

Either you have fast charging turned off or something is wrong with your charger/battery. turned off my phone charged 0-100% in 79 mins.

Yeah, his phone is broken or misconfigured if it charges slower than a Note 3. I've owned both, and the note 4 charges WAY faster.
Sent from my SAMSUNG-SM-N910A

I agree it is very noticeably faster. N3 was decent already with the provided charger, but N4 charge blazes.
Kinda want to get that Qualcomm fast charge 2.0 car charger so I can charge from 12v sources. The standard usb 5v 500mA regulated charge is pitiful

I have to constantly kill Index Service. It's loading CPU up to 100%. There's a bug since at least Note II. If you have large PDF files or many files of any kind, it will never finish indexing. Some reports link it to 64GB cards, but mine does it even without the card.

I would hope so as my device is 3 month old and im guessing ur device isnt that old...it would be horrible if batterys were going wrong that fast...no i would say its got something to do with the device judging the level incorrectly fo whatever reason and your idea of calibration is the right direction....i think im going to try as couple of suggestions in that link myself tbh.....if ur battery was to be lasting like an hour though then i would say somethings not quite right.

I quickly resetted the fuel gauge in synapse.. And waited a few minutes then it died. Then I plugged it into the charger (did not touch it) till it reached 100%. Seems to be fixed now I hope.

The battery seems not to handle gaming very well i think, those drop are from playing brave frontier am still currently sitting at 38%

I bought this tablet 3-4 days ago. I installed this warship game. I also noticed that it literaly jumps from 30% to 3% in just 5 minutes or less. But my battery charges very quick,which is good on the other hand. What is going on whit this tablets battery? My tablet is still stock,not rooted and bla bla... LTE version offcourse. I'm not sure,but i think it started draining the vattery as soon as i insrted the memory card.

That's the problem I had on me T700, thank God I don't have this issue on the T807.
Funny thing, when the T700 battery died, I'd turn it on after 3 min and would show battery at 23% again and I was able to use it for another 15 min or so

I also had the battery problem,too.
After three days suffering by test all the method I Google from internet, I return my T705y to samsung,and they replace the board and battery.
Now everything's fine, try it,just return tabs to samsung.

tab s 8.4 lte battery only shows 2100 mah fully charged
I purchased a new oem battery (4900 mah) and put that in and it is still showing capacity for the battery as 2100 mah...have not a clue what is wrong?
