Nexus 7 battery life

Hi I have recently purchased a 32gb nexus 7 and I have been having some issues with the battery since the 4.2.1 update, before this update I would get around a day on the battery no problem now I can't seem to get more than 16 hours at the most. My usage includes facebook at night for roughly 2 hours, moderate gaming during the day, and some web browsing in my spare time. All this was never a problem on 4.1 but in 4.2, the battery just seems redundant. I would like to hear your thoughts on your battery life on your nexus 7's thank you.

How much gaming is moderate?
I noticed my governor was on interactive tonight, which was maxing the CPU even just by touching the screen, I thought my battery life seemed quite good though.
Anyway, I changed my governor to ondemand, and noticed that simply touching the screen only moves the CPU freq to 3-500mhz.. Which is fine for browsing etc... I have also played games, and I haven't noticed any lags... yet... But if there is a really hungry game that I do start to notice a lag in, I'll just put it back to interactive for that game, and meantime I should have better battery life.
Like I said, I only just changed this, so I'm yet to see how much better my battery does, but just from looking at CPU freqs I'd say there's gotta be a decent difference.
There's an idea for an app for some dev... Per app governer setting...

I always had excellent battery life, no matter which android version.....

Do you use Google Currents? If not, stop the service and disable it completely.
Furthermore, please post a screenshot of your battery usage.

That's pretty damn impressive. How much screen on time is that?
On my second charge I got ~2.5d with about 4-5 hours of screen on (stock). More than satisfactory!

Default governor is intended to max the CPU when you touch the screen, in fact it's an advertised feature for the Nexus 7. There could perhaps be a step up to a higher CPU then higher yet if needed, but the problem with that is you get jumpiness if you switch CPU speeds around when things are going on, like launcher swipes, games, etc.
Per-app governor is already easily done today in Tasker.

Hell naw, just set it to only sink on charge
That means I update my articles in the morning and evening only, and whenever else I plug it in.

Thanks for that, I'll check it out. There is no performance loss when web browsing or similar tasks with the on demand, so I'll just use interactive for intensive games, and extend my battery a bit in that case.

Well, I'm now a happy guy.
Downloaded tasker. I now have my pad set on ondemand for browsing and light duties only with a 1ghz cap which I cannot tell any difference from stock clock,, and then when I launch any intensive games I have tasker automatically overclocking to 1.5Ghz, changing governor to interactive and closing some stuff letting my pad concentrate on the job in hand without me having to do a single thing. Then when I exit my game, tasker automatically clocks back down again and puts the governor back to ondemand.
I also have it automatically only use Sync if the battery is above 40%. I'm liking tasker, and these are only very simple uses for it, some of the example ones are really cool. @khaytsus Thanks again for telling me about it, wouldn't have known otherwise. Now I want to get more into it and seeing what it can really do using the variables etc, and the appmaker.
Another thing about battery. I got my n7 as a US import to the UK, and just noticed today that the charger they supplied me was 700mA instead of 2A,, so I went and bought a UK to US adaptor so I could use the ASUS OEM one, and its charging loads faster, should be nearly 3 times and so far it does seem it. If I was playing a game while charging, say Vice City, before I was able to actually make my N7 lose charge. Not now. So anyone with the slow charge problem please just double check your charger, just in case,, there's probably someone else out there like me that just didn't bother looking and is using a 700mA one.

Nice. I'm assuming there wasn't much gaming in your 8hrs of screen time. Still great battery life though. As long as I can do anything I like in the space of a day and be sure that I'm not going to run out then I'm happy.
I am still thinking of investing in one of those 10 or 12,000mAh battery packs though, just for times where I have to leave the house and haven't had the time to give it a full charge.

Hi guys,
Its been a while but meh.
I just need to know how to get the best out of my battery on szeszo's CyanVIVO 10.1. I am currently using the conservative governor... Any tips to save battery?
Cheers,

I'm no expert but when I was on a rom like yours, my battery life seemed to go down when my brightness was up.

Yeah but my brightness is as low as possible... I have put my Max voltage to 768, see if that helps

10-15 hours is quite a lot. Try to buy an extra battery. :good:

I used different ROMs and collected a lot of tips-n-tricks for a better battery life.
1. The less home screens you have, the better. Each swipe action, though it sounds strange, requires up to 100% of your CPU which hits the battery life. If you fit most of your icons and widgets to 1-2 screens, it will save your battery, because you won't swipe back and forth.
2. No need to keep the brightness on the lowest level, if you are using the ROM which lets you calibrate the backlight levels. Spend 1-2 days on choosing a comfortable level of brightness for each level of outer light intensity.
3. Move all togglers for WiFi, GPS etc. to the main screen (Elixir 2 [Widget] is a good tool to create a control panel) or to the notification area. It will remind you that some functions are turned on, and you'll be able to disable them. I always disable WiFi in the office, because I have a decent amount of free Mbs to spend, and our WiFi access point is 'blinking' making my phone reconnect again and again... you know. Don't forget to turn off GPS if you don't use it frequently.
4. Don't let your widgets synchronize the data too often. It's better to use synchronization on demand.
My phone with CyanVivo 10.1 aboard is able to live for 15 hours without recharging which includes web browsing, books reading, calls making and a bit of gaming. I guess that's the time period you need...
If you want, I can tell more about the apps that I'm using.

Thanks for your replies guys, I can definately see an improvement in battery life, but how do i change backlight levels? I want to be able to game with a decent amount of battery left. I only have three home screens and my Bluetooth, GPS, and WiFi is off when unnecessary.

If you're using CyanVivo 10.1, you have this feature.
Open Settings -> Screen, choose Brightness (I can be mistaken about the actual option names, because my system language is different, but I hope it won't mislead you), check 'Auto' box in the dialog box and touch the second button below (Customize or Calibrate or whatever -- again, I don't know how it's called in your case). You'll see a list of brightness levels which your device can distinguish according to its light sensor. Shift all runners to the left. Walk around with the device in your hands, look at its screen under bright daylight, in the room near the window, in the elevator etc. As soon as you see that some level is not comfortable to you (too bright or too dark), open this screen again, look at the current level (displayed at the top of the window with runners) and adjust the setting for the corresponding brightness range.
Remember that each next brightness level must be higher than the previous one (you won't be able to move the runner more to the left than the previous one.

Hi,
Can you tell on what level current you have while phone is in standby? Using for example CurrentWidget.
I have at about 60mA level. And I think that it is too high. Battery drain at about 2 or 3 percents per hour.
Thank you for your answer.

Disable Google Now and Google Location History. They're draining the battery as hell.

DS Battery Saver
I tried DS Battery Saver, it helps very significantly, when I lock the screen, it auto-cut the wifi and data, and only wake up for a 1 min every x hours, I can set the plan, it's an amazing tool. Now I can use my phone for 15 hours in average.

Nexus 5 Battery Results

I'm doing a low to medium usage test with Bluetooth, Location Access on High accuracy, WIFI, HSPA,Auto Brightness and google now. From 100% down to 0%. Then doing a Full charge time with phone turned on.
Will be posting screenshots via dropbox below with a few hours in between.

In addition I've used a2dp audio stream for an hour or so. I'll do a full screenshot of all the on times later.
Still very low usage scenario. Battery looking good. @22hrs 40% with updated screenshots above.
Final Result only took me to 15% with 1 Day 16 Hours. Screen on time 3hr 16mins. Needed a full battery for the day and couldn't risk it but atleast it's a general ballpark. https://www.dropbox.com/sc/oaj33ji9kssx5rt/BFiLIz-Jef
40 Hours is still pretty good for light usage. During a busy working day i would be happy with 9 hours max usage.

It looks ok with almost 2h of BT streaming calls + 2h of music. Other results in thread seem more "realistic" (if you don't use BT). Let's wait for more feedback. If it could make 4-4.30h screen on for me, that means with custom kernel and UC it could easily hit 5h or more. *thinking out loud*

Here's my reply from the previous thread...
Well you say it's disappointing but I disagree;
If you look at the screenshots you will see how much battery has been taken by the voice calls compared to screen on time;
30% of the total battery use was from the 3hr47m for screen on time but...
A whopping 26% for only 1hr28m of voice call time! If we use that ratio and just double it (assuming all network strength was the same) you'd likely lose 52% of your battery in just under 3 hours...(this is just an estimation based on my results btw).
I honestly don't understand the hard-on people get for screen on time when voice calls seem to drain the battery much much harder... doesn't anyone use their device as a phone anymore?
Also if you take into consideration how bad my signal was the battery life I had today was all the more impressive.
A Random Afterthought:
IF that 26% that were used on Voice calls were used for screen on time...although realistically it'd probably be something like 17-20% with the rest on random android processes and processor usage; the screen on time could easily be above 5 hours possibly pushing 6 with bad signal and no wifi O_O...

Well nexus 4 with Trinity kernel gets 6-7 hours so with nexus 5 I expect around 8 hours on a custom kernel and stock should get around 5 hours which is pretty darn good.

The battery performance results you have are perfectly acceptable for a typical phone user that uses the phone for calls, web surfing, google services, movies etc. I only get 2 to 2hr. 15mins on my N4 with typical phone usage as you. So the N5 is basically getting better battery performance then the N4. :good:

How to get 6+ Hours screen on time!

ok so to do this you have to have a rooted phone and maybe custom rom for certain tips
1) not everyone will want to do this but, for me I mainly use my phone for things like facebook,chrome,texting,instagram social stuff and to be honest the proccesor at 2,2ghz in unnecessary for these apps, I would recommend people like me use the app 'setcpu' and underclock the phone to run at 1.2-1.5Ghz, i don't see any slow down! you can set things to change for example 'if gets below 10% it will allow you to underclock more to save battery' or if 'certain apps open it will fasten'
2) custom rom, use smart 3g, this will turn your phone to 2g when phones screen is off so you still get notification but is'nt draining as much battery
any more tips reply and ill add!

Could you give more details about your personal setup, like what ROM do you use and so on?!?

Agreed. I can get 5+ hours on a Mixture of HSPA+ and WiFi overclocked to 2.5GHz.... too many variables including signal strength and how the phone is used.

I guess the CPU speed shouldn't matter since the nexus 4 is still butter smooth running at that speed.

I suppose really the claim in the OP is that these settings will give you over 6 hours screen on time. You're right that it will help some people, but it also will not help others. Perhaps a better thread title would be to state that these are tips to increase screen on time.

I've been averaging 5hours with LTE on all day one gmail account syncing email only. 2hours of Pandora various browsing on xda, eocf, overclockers forum, Facebook via browser about 20minutes of voice calls, gtalk all day with the wife, etc, etc. This is with every ROM I've run so far all with stock CPU settings. Also, currently running the linaro ROM with the linaro Franco kernel and the moto x dalvik patch extremely debloated.

This thread is pretty helpful to me. If you don't find it helpful, it's not required reading.
I'm considering setting up a Tasker profile to manage CPU speed. However, I'm trying to get an understanding of default behavior before I go changing it. I've been checking CPU range with ROM toolbox and the max seems to be changing. I'm assuming that this is due to throttling.
If that's correct, what is the absolute max set to by default?

sour grapes... it will help some ppl, not others... which goes for just about every thread at XDA.
I'd much rather see "partially helpful" threads than not. I can pick and choose which apply to me, rather than not seeing them at all.

Instead of using the steps in the OP, I just use DS Battery Saver and Greenify. It's that easy.

My battery life doubled when I knocked down the screen brightness from 2/3 to about 1/3. The screen is still plenty bright at that setting, and the battery is much, much better.

Yes brightness is a big help. I use "display brightness" which puts an invisible slider up the left edge of my phone screen so I can manually adjust to my liking

Just fyi, your phone does not run that speeds at all time. You can also lower the minimum frequency and it will help alot. Lowering mine from 1100 to 600 helped a lot.

[TUT] Extending Battery Life

So our phone has a lithium Ion battery right? Well heres some things most people do not know about this type of battery.
Sorry if this has been posted before!
Li-ion batteries begin to degrade as soon as they start to be used.
One cycle is based on a 100% depth of discharge (e.g. discharging from full to empty), the potential number of charges can be increased by not allowing the battery to become fully discharged before topping it up. For example, allowing a fully charged battery rated at 500 cycles to drop to 50% before recharging could potentially triple the number of charge/discharge cycles to 1500 before the battery capacity degrades, thus increasing the batteries overall lifespan. However, this also means the battery will need to be plugged in more regularly.​
This means that keeping the phone topped up, and not waiting for full discharges will potentially extend the battery life of the phone.
In no way am i saying this a definite thing, as i do not know, and this wont extend your screen on time if that's what your after, it will offer you the same amount of screen on time, for an extended period of time.
So to conclude, charging little and often can extend the life of your battery. In theory anyways. I read up on this from a few articles and websites, too many to reference, but this is the combined knowledge i found.

There are still a lot of people who thinks that you must discharge to empty.
This was required when NiCd batteries were in use. Li-Ion are different.
Thanks for posting that! :highfive:

I have read on Note 3 forums how people cry about their battery life.
Thwir new software upgrade lowered thwir screen ON time to "only" 4-5 hours from 6-7. Whereby I am more then happy if i get 2-3 hours of screen time.
It makes me question my battery and software...

Friend, I wrote it looking at the topic of the thread. Hope this will help people who are looking to optimise their battery by tweaking some settings in CM 11.
At least helpful to those who have subscribed to this thread !

@sPEADy and @prem911 what ROM + kernel combos are you guys using ? :good:

@sprite048 I am using the nightly form 07th January.......and all defualt CM did'nt change anything

best battery saving strategy:
1) turn off wifi and 3g
2) put down your phone and pick up a book to read
3) dont touch you phone, use the landline to make call and laptop for messaging
right, speady?
Just kidding, WiFi and 3G are actually your battery killer. I'm currently using CM11 and can have 3 hours light gaming (Plague Inc.) with 700MHz CPU and 200MHz GPU settings. Another tip is dont use background process (such as news, email or even swiftkey; Google location accessing as well), they do wake your phone up regularly to sense if you have connection with the Internet Lord.

I do get 2 and half hours of screen time with 2 days usage. I did post in Carbon Rom 4.2.2 thread 4 hours of screen on time few months back so I do use my phone a lot when needed.
