Does My Battery Seem A Bit Poor (amongst other things)?

Hi all, new Nexus 7 user here! I'm really liking this device and its definitely a keeper. So far, I think I've dodged most of the known issues such as screen lift, dead line of pixels, sound issues, etc.
One thing I'm noticing, or maybe I'm paranoid, is that I "feel" my battery is draining somewhat fast (compared to my iPad 2).
I'm not running a lot of widgets, only a clock widget, weather widget, and settings toggle widget. Also have sound boost and terminal, which I think are also running since they're always shown in the notifications center. I can't provide a screenshot since I'm new and it won't let me, but here are the stats:
28% and Discharging
1d 12h 7m 30s on Battery with screen taking up 77% (~33% brightness I think, the screen is really bright by the way!)
Time On (Screen) 4h 35m 1s
Basically all my use has been web browsing, via Chrome (tilt thing turned off) and Dolphin HD, and maybe 20 minutes of light gaming. I don't have Push Email turned on, its on Manual.
Anyway, if anyone could provide any insight as to whether my battery performance is on par or not, I'd really appreciate it!

Close terminal when you're not using it.
I get about 6 hours screen on time. Your battery seems fine, idle time with wifi also uses battery so by the time it runs out you'll have like 5 and a half hours plus the idle time. About normal.

Hi, thanks for your reply! I have terminal on because I'm currently doing the manual fix for smartdimmer issue. I'm not sure if turning off terminal would kill the fix, I'll go and tweak around a bit.
I just don't understand how various review sites are saying it lasts 9+ hours though, seems a bit out of reach for me currently.

It can definitely last that long with use, some users have reported that. Likewise, don't think anything is wrong with your device.

Thanks for the vote of confidence! I've seen from the battery post various users posting very high battery life, and it all made me very shiny-eyed! Haha. Anywho, I guess I should just go and enjoy this thing instead of being all OCD.

I'm actually getting a little bit worse than that myself, so I wouldn't be alarmed at all
And this is my 3rd Nexus 7 and all of them have had similar battery life to yours.

Thanks for the reply. Feeling much more confident now.

I am using auto brightness and my room condition is usually on darker side these days so I am getting very good screen times although I have turn of prism feature of Tegra 3 which used to cause over exposed colors during and after video play back. Turning off prism does hurt battery a bit but I am still getting very good screen times using xda app, chrome and YouTube. It might be the reason that mostly my room is on darker side and I am on auto brightness and the screen does not have to pump high brightness all the time rather only when required.
I am attaching some photos and in this particular instance I noticed that I didn't use my nexus 7 for 10-11 hours after fully charged and of course unplugged from charger. There was zero drop in battery percentage for those 10-11 hours although the screen time was around 23 mins during that time because of apps refreshing etc which you can also see from screen shots. It seems that very easily I am going to get 8+ screen time which is very impressive of course when I play games in between then it goes down to 5-6 hours screen time. This is the first instance where I have not played any games. People do say the battery consumption is not linear but so far it is relatively linear for me.

I do get full bars of WiFi and I don't have any problem with WiFi which some people are reporting and this does play and bigger role that is when your WiFi signal is weak then your tablet has to use more juice out of battery in order to make an effort to enhance the signal strength. I am sitting 15 feet from router most of the time.

awesome friend . very nice. my brother have z1 so i can see the different . the quality and the colours are much better in Z2. you can see a massive different .
Thank you

Looks too good man, nice battery.

Well, battery looks like to be similar to Z1. It's 40% @ 3h 24m screen on time, so it should be 5-6 hours screen on, like my Z1.

I think it'll do better than that. Z1 can only go for 4 hours max with auto sync, 3G and WiFi on.

I hope so. Anyway, im very happy with my Z1 batter life, more then happy.

As long as it can hold a whole day, I'll be happy. It can't be worse than my Nexus 4 not even holding a whole day.

Looks like a real phablet performance. My old Note and Note 2 could easily last 2 to even 3 full days with light "as a phone" usage.

How do you get a model so early?

Thanks for sharing, what's the longest on-screen time you've achieved? How much % brightness do you use?

I Wonder the same thing
Skickat från min GT-N7100 via Tapatalk

well as i know his friend gave him a protocoltype version before release and all leaked photos were from his phone

Now have second thoughts about buying Z2. I never get less than 8 hours screen time (over 24 hours total time) on my Note 3. Tho I am using a custom kernel.

So with 2600mAh battery HTC just did a great job of 71 hour endurance,
do you think that with 3200mAh battery Sony will do much longer cause it runs in the same chip set and all.
Xperia Z2's display is slightly bigger than the HTC One(M8).

The Z1 came up pretty short despite the 3000mAh, so Sony needs massive improvement over efficiency. I think it's doable on the HW front, big question mark is the screen that let the Z & Z1 down. Fingers crossed.

I don't know how sony managed to screw the battery life on the Z1, that battery is huge and yet it underperforms, I hope history won't repeat itself with the Z2 :crying:

It is the screen, the best example is the Xperia Z1 Compact. it's doing a good job with 6hours of screen on time.

2 Days of Battery Life, That's what they promised

As you all know The Sony Xperia Z5 series is said to be able to last for 2 days. As long as the device is not released yet, we just have to wait to prove it.
So, as I searching around in Youtube, I've found this
https://www.youtube.com/watch?v=vxYhhkWgQx0
I was stunned. What !? 2 Days on Z3+ ? It's ridiculously impossible !
in my normal use my Z3+ only last for 3-3.5 hours of screen time, 4 if lucky.
and the goddamn heat issue is still there, even worst you can notice performance dropped dramatically when CPU gets hot.
To be clear I never use Stamina mode, as it decrease frame rate (Which on my old Z1, it is never happened. Back then I always enabled Stamina mode)
therefore, The fact that Z5 series still use SD810 (even they have dual heat pipe) , I don't think 2 days of battery life is going to be possible.
Or they might be a chance that they would successfully fix both the battery and heat issue on upcoming 5.1.1 (maybe that's why they delayed it)
So, Let's hope

Let's hope for that but still waiting for 5.1.1 for z3+
ME

When have manufacturers not exaggerated their devices' battery life? I didn't think anybody took those claims at face value.
Two days is possible with light use.

I usually have like 1,5h of screen on time and 15% battery after ~20 hours. Stamina mode does literally nothing for my battery life, if something it gets worse.
I don't know how Sony usually rolls but if I were them I'd go directly for 6.0 and skip 5.1.1.

Since last charge i've got 2h15mins of SOT, And 19hours total Idletime - Battery is at 58% now. For me it's okay. Depends on your usage profile and if you are on Wifi or on mobile data (once again, look up the "mobile radio active bug". Maybe a Mod should make a Sticky with this and the PC Companion Repair to fix Overheating...).

As @[NUMINIT] said all the manufacturers lie about the battery life but they lie too much about this particular phone. It doesn't even last 1 day. My Z1 was a really great phone, this one is like something to half way.

With light use, I can easily get 1 1/2 days out of this phone. Your experience may differ based on different usage preferences and patterns.
Can I ask what you're hoping to get out of this thread?

The crucial thing is they say "up to " meaning it not definenent but it can last up to 2 days ,I use mine for work and does good job in this role ,I get 2 days and about 2 hours screen time but every device and user experience is different,still doesn't beat my old z3c at battery life

Another thing : if battery life seems so bad far you, why not posting a Screenshot of the battery stats and usage in the battery life thread? This whole "this device sucks" - things is getting on My nerves.

Mine too, but hey, it's easier to ***** than actually look for a solution.

If you don't use Stamina, chances are good you have the mobile radio active bug. I use it and get around 4-5 days. Last Firmware were only two days. I don't have lag or unusual heat as well.
Done a factory reset?
Gesendet von iPad mit Tapatalk

It says = 1 day 19 hours 4 minutes
Only 5 hours to go

One more proof. It exceeds 2 days. BURN!

All I want is to share my experience and yeah, I kinda *****y about it
But hey, I didn't get the phone for free. I do think I have right to complain about the issue.
I'm glad for those who are not facing this problem. you are lucky bastard.
I will wait for new FW to see if it solve the problem. If not, maybe it's time to say goodbye with Sony

Guys, check out the battery life thread for nasty lollipop bug called 'mobile radio active'. My Xperia Z2's battery life was legendary on Kitkat & then it hit the rock bottom when lollipop came out. Same issue with my Z3+, S6 & unfortunately I don't have the option to downgrade these two to kitkat. Lollipop is the only reason why all 2015 phones' battery life sucks big time. Z3+ battery life is still a lot better than S6's if you're into heavy browsing. You'd be lucky to get anything better than this until Google fixes this bug.
It's been told here multiple times - few things you could do to improve battery life
1. Always close all apps (from the MT window) before locking screen while you're on mobile data
2. If you're on wifi 24/7, turn off mobile data permanently
3. Use 2.5GHz Wifi instead of 5Gz if possible
4. Make sure 'Screen' is on top of the battery usage list. Otherwise, you got radio active bug or something else that's draining battery. That said, 'cell standby' tops my list occasionally if I don't use it for a long time. It doesn't affect heavy users but Sony needs to work on that.
5. For past Xperia owners, Z3+ screen is much brighter than Z2, Z1. In order to get Z2 like battery performance, you have to lower the brightness. If you leave the brightness slider at 'zero' with adaptive brightness on, it's still much brighter than Z2 & drains a lot of battery. Stick to lower manual brightness if possible.
6. Root

Sony said up to 2 days. So it is not 2 days. It depends on your usage. My sometimes gets 2 days but if I use it more I can get 1 to 1.5 days..

1.5 days is a lot (for me 1/3 of a day is so much), I am working in a very hot place (Mérida México) and I can take one or two pictures then it get's almost on fire and the app closes, video is a shame pain lag, I can not record 5 seconds... if the app didn't close the video looks like a sequence of photo shots... my first nokia 3250 with symbian makes me happier in that era.
Sony:
Like @ing005 say it's time to say goodbye to you and your new "super" spec's devices, you are using us and we have to pay for tasting.

Actual Z5 owners... Post your screen on times

As the title... To get a good average example... Please post (ideally with screenshots of battery stats) your screen on times for a single full charge of battery and please state whether you have a Z5, Z5C or Z5P . Whether you have sync and data/wifi active etc.. Auto brightness.. Any other deciding factors
Thankoooooo

3 hours, only my second day but thats with bluetooth/wifi on all day + full brightness (auto) + I live in a poor signal area
I am sure It will get better, its definatly far better than my galaxy s6.
Possibily very slightly worse than the Z3 but too early to tell.

3hrs SoT, WiFi all day, down to 29% now... Not stellar.

I've gotten 6 hours on my 3rd day, but I spent around 3 hours underground, so flight mode was switched on. Overall, I've spent a couple hours listening to Spotify and redditing for the most part of those 6hrs. I am pretty satisfied with the battery life, it's just a little bit worse compared to what I was getting on Z3.

5 hours in typical use with wifi or 3G data on.

~4.5 Hrs. Posted some screenshots -> http://forum.xda-developers.com/showpost.php?p=63442175&postcount=97
Mine will soon hit > 5.5 Hrs though

So far so good for me. Before my Z5, I has a OnePlus One (known for its stellar battery life). Yup, the Z5 battery seems to drain faster than the OnePlus One when using it, but on the other hand I noticed it seems to use less power than my OnePlus on bluetooth + screen off, in the car. I always listen to the same podcast when I go to work in the morning (it takes 1 hour), and my Z5 lost only 2% this morning (from 100% to 98%). My OnePlus One would usually lose 4-5%.
I received my Z5 yesterday though, so I'll let it settle down a bit too. I will report back in a few days
Awesome device though. It's well built, it feels very premium compared to my older phones (a cheap OnePlus One that I liked a lot and an ugly but very good Galaxy Note 3)

Today I'm at 2hrs sot, and down to 40%. I've been offered a full refund, and I'll be taking the phone back on Monday.
I'm very disappointed in the z5, and perplexed how others seem to have great battery life.

Today so far and i was sat nav'ing for half an hour

I personally get decent battery life by deactivating 4G

So Xperia Z5 can make it to 6h SOT with stamina mode on and 3G as prefered network.

Same is true for most phones, 2G or 3G networks use less battery. But running in 3G is like owning a Porsche 911 Turbo but never taking it of 3rd gear.

Screen on time

It's amazing how much we actually use our phones in a given day, especially when we watch "videos"! Rate this thread to express how many hours of screen-on time you can get on the HTC U12+ before depleting the battery.
Then, drop a comment if you have anything to add!

A full day of use can easy be achieved using the U12+ with an on screen time around 4/5 hours.

I usually charge mine every other day with about 6 hours of screen on time. My wife, however, managed this.

Wow that very impressive screen on time. Any more information on her usage? Just Facebook for example?

I realized, after posting yesterday, that she could have had some charge time in there(forgot to check) and that would have made it look like SoT was longer than it actually was.
I checked her phone again last night and she had 6.5 hours SoT and 21 hours since last charge with 3% left.
She plays mostly casual games... Grow Castle, Neko Atsume, Candy Crush.

Thanks for the info. I find I'm getting 3-4 hours SoT whenever I play any games, but usually gain an extra hour when I'm not playing games. Wasn't sure if that's normal or bad considering what you posted about your wife's habits.

Battery life seems to be on the lower end of the spectrum. My Pixel 2 XL gets much better battery life compared to the U12.

Just bought the phone for a week, all is perfect unless the battery .
ideal time is fine around one day and more, screen on time around 5/6 hours.
if your change the display resolution from Quad HD+ to FHD+ it will give you extra one hour .

thats not poor battery life, is average i would say

Battery is even better on latest update. I would get even more if it wasn't for me being in work and getting a weak mobile signal 47% from this. 1 Day and 19 hours 30min on a full charge with just under 5 hours screen on time, usage from games, youtube, Facebook chrome, phone calls so a high usage also. I am very happy with this phone battery.

Anyone also have the HTC U11? If so, how does it compare in screen on time? I'm considering upgrading, but don't really want to take a big hit in that area.

Anyone else?

Nobody? This thread seems to be dead like HTC company.

First charge looks promising

Hello,
If I compare the screen on times of my new HTC U12+ with your pictures, could you please tell me what did I wrong?
Screen brightness is about 15%. Apps like Facebook, GMail, Google Drive, Alexa, Messenger, News Republic and so on are deactivated.
I reached 1 hours 38 minutes screen on time with 33% battery left.
Please advise.

i would uninstall that batterystat app, those are only useful if you want to find battery draining apps and they drain battery in return.
