Play time - Nexus 7 General

Hello all,
This is my first topic on xda, and im really excited
I got my Nexus 7 only couple of days ago, but I noticed that the battery hardly stays 6 hrs, when I'm only browsing or tweeting.. Etc. That's although its clearly mentioned -on google play- that it should stay up to 10 hrs of browsing & 9 hrs of watching HD.
How can I test the actual battery usage, to make sure its performing well? Also, is there any tips to decrease battery usage, and increase its efficiency?
Thanks in advance..

I don't know what your problem is, probably something is draining your battery madly! I would suggest installing juiceplotter from the market, and then downloading super power v0.75 BETA. With juice plotter you can see what state your phone has been in (screen on, aon, wifi,...) and super power lets you very effectively control what your phone is doing. These are the two apps i use to substantially increase my battery life! Hope some of that makes sense and helps..

Thank you I will definitely try it out. Will it tell me what's using the battery?

You can easily see what is using your battery. Go to 'settings', then 'about phone', then 'battery use'. What does is say there?
I have seen a lot of people complaining about battery life when using CM. Not sure if that is a coincidence or not... Maybe do a Nandroid and try the stock ROM for a while to rule out a ROM issue?
It will show you if your screen/apn/wifi was on our not. Also if you charged your phone. You will have to play with it for a while till you understand which color indicates what but after that you can analyze what your phone is found doing on one sight! Complemented with super powers functionality it gives you a couple od great role tools to adage some good battery!

I'm on 15 percent battery already
It's funny cuz it says 6 hours and 15 mins since last unplugged but its been 12 hours.

So it's lasted 12 hours, using the screen for an hour and 17 minutes worth of voice calls... I guess that doesn't really seem right to me, although maybe if the screen is 100% brightness... Maybe turn it down to 50% and screen time out to 30 seconds?
Have you always had this kinda battery life?
Can you try these things? :
type in *#*#4363#*#* in your dialer. Select battery information. Is battery health good?
type in *#*#4363#*#* in your dialer. Select battery history. first drop down select partial wake usage. Is anything look out of place (something much larger than the rest)?
Maybe download a program called traffic stats lite? This program will tell you which apps have been transmitting data and how much. Possibly a rogue app that is transmitting all the time?
Hi tech338. The battery health is good and I hardly ever have my screen on 100 percent bright. The battery was definitely better. On the partial wake lock the only thing with the highest bar is android system. The blue bar is half way up. And its at 1 hour and 17 mins
Thank you

It's a been a problem with almost all smartphones not just android. The only solution I've found and most reliable is to have a spare battery.
You can try my battery app linked in my sig. It pulls the info from inside your battery chip to re calibrate it.

Post you battery life chart here!

I literally cannot take this phone off my hands but I tried to test out how long the battery could last with few gaming and browsing with light usage and this is what I got
I'm really impressed with standby times

I found there might be some defective on software or sth else,
some batteries drain so fast, some are not.
for example, mine never last over 24hr even i turn off everything, use only 2G, with no app installed.
and it's instable, sometimes it drains so fast, sometimes not. I don't know why.
Until we get a software update probably will be great battery like the update for one x

Same here my android system is on top, even after deleting some stock apps and disabling fast demorcacy. I usually get screen time of around 3 hours 10 mins which is poor.

I think that is why many of us expect a huge battery improvement after updating to JB ,perhaps the newer system wont be so power hungry.
these screenshots are fun and all but they are totaly irrelevant.
hoe much USE time are people gettng is whats interesting.
so screen on time.
as the goal is no drain with screen off and as long as possible screen on time (this is when you use apps and so on).
my phone can be on for 2 days and still hve 95% juice left but thats kinda irrelevant if i dont touch it.
when i use it non stop my use time averages on 4 hours and 15 minutes so far.
all the people having problems with battery drain must have either bad apps installed of verry poor wifi/3g connections.
as in a good serup with no bad apps and good signal wifi should not drain battery at all if your not using it.
i would so like all people with issue to lend me there phones for 3 days to see if in my stable envourement they have the same issues.
im fairly sure that all these problems are signal and user related and that it has nothing to do with the hardware.
My phone would only give me 2 hours max if the mobile data is on with sync off facebook sync set to 1 hour and hotmail sync set to 1 hours. But if wifi is on throughout the day i would get around 3 hours 15 min average with sync on hotmail set to push and facebook sync set to 1 hour. The battery is really poor as i only use it generally for txting whatsapp and just a bit browsing thats all nothing else. When i watch videos my phone consumes less battery, than normal usage which i do everyday. The highest screen time i have ever got was 4 hours 15 mins thatd because i watched a video for almost like 3 hours thats why. But the battery is still really poor

My android system also consumes a lot of power, its always on top no matter what. I am running on V_10H I disabled some stock apps using titanium backup and used fast demorcacy but the only difference I could see was android wakeups had been much lower thats all and so less power consumption when phone on standby thats all.

this is totally relevant information for regular users.
many people complain about battery drain and that a custom rom is the cause or custom kernel when its available, but what shows that it is not, is when you can place your handheld mobile or tablet alone with wifi set to instant off and you got 3g disabled and it lives for days without loss of battery, you know that it is stable.
when you suddenly lose battery in hours and previous tests showed it was lasting days, you can be sure you got battery infected apps trying to activate your cpu all the time.
i'd like to buy this phone but i'm a bit afaid of the battery drain. people who says it last 2 days with normal use other says that with gaming and browsing lasts 10-15h but a lot says that the battery lasts just 6 h with normal use... can someone who owns this phone and he use it with a middle-intense use (texting,browsing,gaming some time) tell me how much lasts the battery please??

Well, my usage pattern is kinda light, but still...
- took it off the charger at 7:15 am
- 3g data permanently on while I'm not at home (from 7:20 til 18:00 or 19:00)
- wifi on when I'm at home (during the night too, I never switch the phone off)
- sync always on (gmail, whatsapp)
- received a couple short phone calls, let's say 5-6 mins
- received a bunch of emails, say about 15 or something
- some messaging (on whatsapp and gtalk, I don't use sms)
- some facebook, let's say 15 minutes (through mobile website 'cause FB app sucks big time, always had and most probably always will)
- some net browsing looking for a few stuff, let's say 5-10 minutes
- checked a couple forums on tapatalk a couple times
- updated 3 or 4 apps on wifi
- downloaded a 50mb game on wifi and played it for like 10-15 minutes
- ebook reading on moon+ for 1 hour and 30 minutes (maybe even longer, didn't check the exact time)
I connected it to the charger when it reached 12% battery at about midnight THE NEXT DAY (yes, that is around 41 hours without recharging it)
Overall, I can say I'm satisfied, at least for my standard usage...
- Stock v10h firmware, no root (yet).
- Nova launcher since 5 minutes after buying it
- I usually keep brightness quite low unless I'm out in the open under the sun, good thing about this phone's screen is that it's usually very well visible even with only a 20% brightness. If I need to use it in full sunlight, I conveniently placed a full brightness widget on my homescreen, and then back to 20% with one click when I'm done. No autobrightness 'cause I don't like much how it's set to work on this phone (was kinda better on my old i9000, but oh well, 1 click widget and I'm good to go, no sweat)
- Disabled 3 or 4 stock apps (through app settings, no titanium or other stuff)
I noticed that battery usage was kinda higher before disabling those stock apps, I guess one of them was a powermonster of sorts (I suspect the meteo one, but I'm not sure)
- No facebook notifications of course, not for battery-related reasons but just 'cause I simply hate them... but I guess that's nice on the battery too

[Q] Battery life

Hello everyone,
I wonder how much battery life you have on i9000 with stock battery (1500mHa) on cm 10.1 with semaphore kernel?
Asking, just because I can only get max. 12h of battery life with cm 10.1 20130218 rom and semaphore 2.9.10, smartassv2 and row. Wondering is this normal or my battery needs to be changed. Any suggestions to max battery life on i9000 would be appreciated too
Sent from my GT-I9000 using xda app-developers app
The battery can last between 3hours and a week, depending on how you use your phone, so that's not a good question to ask.
If you feel that the battery is running out too quickly then download betterbatterystats and look for any apps using unusually high partial wakelocks or alarms and get rid of them. It only takes 1 rogue app to screw up your battery life.

I think he knows that.
12 hours uptime is not uncommon, especially when on 3g a lot. On wifi you should be able to get at least 20 h in my experience. If the battery is as old as your phone I suppose its capacity is not what it used to be, and you might consider replacing it with a sgs+ one f.i. - they come cheap nowaways!

That's in your experience, the way you use your phone.
Try playing NFS MW or something. You'll get about 2 hours on a gti9000. It varies far too much to try and tell people how many hours battery life they should be getting. Totally depends.
Sent from my Nexus 7 using Tapatalk HD
I use my phone for 3h wifi browsing, 30 min. music and 30 min gaming, but nothing intense. And with this usage I get 12h battery life. Flashed 2.3.5 stock rom. Still getting 18h max. So I think this comes to conclusion that my battery is old enough. That's why I asked for the battery life you get, because I didnt knew this is usual or not
My last for 2 days more or less depending on usage.
AW: [Q] Battery life
Guys i think its wrong to measure the battery life with how long your phone is working. i personally look at the screen on time it says more than just how long our device is working. I get always stats around 3h its unimportant if my Phone works 6h or 18h.

Lollipop battery life results

Hey guys.
I'm sharing with you my nexus 5 battery life results on Lollipop.. With heavy use.
By heavy use I mean these tasks:
-Listening to music almost all the time.
-Playing some games (subway surfers, asphalt 8, Dead trigger).
-Recording some time-lapse videos using Framelapse.
-Heavy use of Facebook app and messenger, WhatsApp, plus some texting and phone calls.
-Some browsing on chrome.
-WiFi was on all the time except when I wasn't near one, then I turned on 3G.
I barely got to half of the day with 3 hours of screen on time before it dropped to 19%.
You can get more information from the attached screenshots.
Any tips on how I can make my phone not drain so much battery? Should I root it? I'm not against rooting it as long as it doesn't decrease its performance.
Much appreciated guys.

[OP5] Battery life Thread

Let's make this the official battery life thread for the Oneplus 5, enjoy :good:
OnePlus 5 Battery Life Thread
Hi all,
I figure it would be useful to get a battery life thread going so we can see what type of performance we can get and also understand how people might be improving their battery performance.
I haven't done one full battery drain yet as I only got the phone yesterday. I will be doing that on this cycle to see how it performs. For reference I am at 90% after about 7 ½ hours having put down at 100% and not on the charger when I slept. I had 2% battery drain over night (slept maybe 6 ½ hours) and have 54 minutes SOT (light usage, just messaging, Twitter, slack, chrome etc) with the remaining 8%. I'm not sure how OP phones battery life reduce, I know LG always has a strong first 10% and then rapidly drops off for example.
In terms of setup, I am rooted and using Doze Settings Editor (GeraldRudi preset), Naptime, Leandroid (but I need to figure out if this is actually working). I am also using dark themes were possible as these are better for AMOLED screens. I've also tweaked kernel in EXKM but nothing major that would positively impact battery.
Just to follow up, I have completed my first full cycle and can report that I got just over 6 hours of SOT over about 33 hours.
I had a bit of Bluetooth and GPS but I do keep the screen brightness as low as possible which really does help battery life as well.
I have also included CPU frequencies for reference, I haven't made any governor tweaks but that would be something to look at or maybe wait for custom kernels which I'm sure would have different governors including EAS based ones.

For a stock rom thats some great values. Im on 40% now and got like 4hrs SOT. Device is running for like 29 hrs. Probably got the same as you

Yeah I definitely think so. There has been a trend in recent years of reducing battery life IMO. I had easily 8 hours of SOT over two full days on my HTC One M8 when I first got it and each year it's just gotten worse to the point now where 6 hours is considered great but I'm not complaining, I will take that over other phones barely managing 4 to 5 hours SOT.
Very excited to see how far this phone can be optimised on battery life with custom ROMs and Kernels. Good days ahead
Make sure to post your results when you complete a full charge and what you've done battery savingwise to achieve that

The battery life in mine is awesome. 21 hours, on 4g/WiFi and 4:30 hours SOT on half battery.
Probably will last me more than 2 days with normal usage
I can get around 8 hours SOT with medium use and brightness set to low. I am mostly indoors and I am impressed. With the same usage on my OPO I got 3.5 hours SOT.
ElementalX and 4.5.2 is out and coming out very shortly so the game will change again battery life wise. There will be different kernels that will help or hinder battery life depending on how much they are geared that way or towards performance.

My first charge was data only. I've had a couple of issues with stand by drain but I think that has been sorted now (back down to 2-3% drain over night) so should be able to get another decent reading today.
I am however now on freedomOS and ElementalX so things are changing up and I can see there is another OTA fix on the way.bit hard in the early weeks to get through a full day without something changing!!
