Gaming Battery Life - Nexus 7 (2013) Q&A

http://www.engadget.com/2013/07/29/nexus-7-review-2013/
Since ASUS has made a considerable effort to slim down the new Nexus, we suppose it shouldn't come as much of a surprise to find that the battery is also smaller: it's been shrunk from 4,325mAh to 3,950. This was worrying at first, especially given the extra pixels that need to be lit up. In normal use, we discovered that the device could easily last us at least a day and a half, and we could certainly push it longer by being more conscious about preserving battery life. Gaming and multimedia were unfortunately different stories: we drained the battery nearly 30 percent in just one hour of playing graphically intense games like Riptide. Our video rundown test, which consists of a 1080p movie playing back on an endless loop with the display on 50 percent brightness, yielded a life of seven hours and 15 minutes, which was much poorer than last year's Nexus 7. That tablet lasted nine hours and 49 minutes in the same test.
(Update: many of our commenters have rightly pointed out that the new Nexus 7 has a much brighter display, which may lead to faster battery drain when it's set at the same percentage instead of a nit-for-nit comparison.)

How fast does your battery drain while gaming? Please mention the game played, length of session, battery percentage before and after, whether wifi was in use, and screen brightness.

With heavy gaming use, RipTide2 or ShadowGun DeadZone (Online Multiplayer FPS) I average around an hour per 10% or less of battery use so far.

Played Crazy Taxi for about a half hour and dropped 5-6% which I didn't find all that terrible. Can't expect the world from the battery.

You get over ten hours of gaming? That is hard to believe.
According to Anandtech, last year's N7 only got 4 hours during heavy gaming. http://www.anandtech.com/show/6073/the-google-nexus-7-review/7
The N7 also fared poorly compared to every iPad. http://www.anandtech.com/show/6429/ipad-mini-review/8
I give more weight to Anandtech's benchmarks that most others. They are generally the most thorough and technical. Although the above are for the previous gen N7, I'd be shocked if the new model can achieve 10+ hours gaming on a single charge. None of the current gen tablets can do that.

I played Cordy for an hour and it ate 20 to 30% of battery.

What level brightness?
According to Anandtech, the new N7 display goes up to 583 nits, while the original only 312 nits. Brightness probably has a huge impact on battery life.

I'm going to need you to re-run that test at 25%, kplzthx.

Is it possible to adjust max CPU frequency in stock Android 4.3?
N7's cpu/gpu is overkill for most games. Setting a freq ceiling might extend battery life significantly without a noticeable impact on game performance.

Going to need to root your device and use an app like SetCPU to lower the clock speed.

What's your battery life like?

For me, with Overclock.. it's EXCELLENT! I can have it in standby but still have background data going (push gmail, twitter apps, etc.) for days at a time and still have some juice left.
Just today with some admittedly light usage (but I did use it) I had battery use time of 12Hrs with over 70% left.
I'm using setvsel @
35 @ 400MHz
50 @ 800MHz
65 @ 1200MHz
CPU Icon is set to refresh every second and it's supposed to cap at Vsel 2 @ 10%. It's as stable as ever.. been running like this for weeks now. I'm taking note of how much I appreciate the excellent battery life I get because my Vibrant has been getting really bad lately.
Running Barebones 1.3 with
19 @ 300Mhz
35 @ 600MHz
52 @ 1000Mhz
Battery Life is excellent - more than 48h without recharging is no problem.
I get 2 days of standby with heavy texting,surfing over wifi,calling and some gaming. DEFY battery performance is one the best amongst all Android phones.

Undervolting your cpu can harm your hardware real badly. I've had my defy stopped working and shut down completely in the past so i won't recommend you OC or UV
EDIT: tho i still undervolt but 19 vsel is too low for 300 mhz, raise it upto 26 or so
Yes, 19 vsel maybe too low, at least in my case. When I ran the stability test, anything less than 24 would hang the phone after some 10 minutes. 24 is fine in my case but I set it at 26 to give a little more juice.
LOL. Why the hell, should undervolting harm the cpu? Undervolting improves your cpu's lifetime, instead! Less voltage means less stress (heat) and less leak currents for the cpu.
Well, it's true that you might have some instability issues, when the voltage is too low. As soon as you experience so, you can raise the voltage a little, until you have a stable cpu. I've been using undervolting for my PC's CPUs for several years.

Never had any problems with my settings, some in this forum use even lower voltages.

The battery life on the Defy is absolutely amazing.
I can easily get between 2 and 3 days of normal usage and somewhere in the region of 4-5 if I use it very little.
I reckon if I switched off 3G, had the brightness down as low as possible and generally tried not to use the phone much, I could push a week.
Sadly, my Defy is 'in the shop' just now, damned earpiece.
What do you guys run on the background? I probably able to get 1.5 days on normal usage. Even after charging and no usage, I lose about 10 % after an hour or so.

It is impossible to get 1.5 day if defy uses 10% for 1 hour standby. Defy rounds 95% to 100%, and 94% to 90%. So it is possible that an apparent 10% drop is actually a 1% drop. You may install Motocharge to see the battery in 1% increment.
I'm happy to hear everyone getting excellent battery life. The DEFY is a truly unique Android phone.. I'm just afraid that us stateside won't get devices like this because of AT&T... the Bravo is a step below the DEFY just because it doesn't share the same faux-rugged water resistant build. I'm glad T-Mobile picked this one up, overclocked it's only a bit slower than my Vibrant in most operations.
Well I did a Quadrant benchmark 'standoff' with a colleague of mine which has a Samsung Galaxy S [EU version of the Vibrant] and I beat him with over 250 points [the Galaxy S did 975, my Defy did 1334], both running Froyo and the Defy being non-overclocked.
I've also noticed that his Galaxy S tends to hang & stutter from time to time. Regarding battery life, he carries his charger with him at all times, I do not, 'nuff said.
I also get ~1.5days of battery life.
I'm able to squeeze more than 80 hours of usage on a single charge running PaYs 5.0. Light to moderate use of WiFi/Data/GPS/BT, no background syncs and most apps firewalled except through WiFi.

i used circle battery widget and it does shows 1% increments. after 90%, it slows down in terms of usage.
i also forgot to mention that my defy sometime runs pretty hot at 35-38C, which i think accelerates the discharge
what about autobrightness? if is set it on, the battery drains much faster.
For me, with undervolt (800/46;600/30;300/18) I can use my phone to make calls, send sms, surf the web, run some apps, and run one a two games.
After 24h of that usage, I have 50% remaining.
a strange thing happened to me (sorry for my English):
Yesterday I installed the camera 360 that did not work it gave some error. Last night when I went to sleep (1-1.30) had 50% battery, in the morning (7.30-8) phone was dead. I put the phone to recharge, from 11 to 3 o'clock phone has reached 30% of battery so i put the phone to recharge again. Until 10 pm the phone has reached again 30% of battery so I decided to give him a factory reset. With 30% i did 100+ app backups with titanium pro and I gave factory reset, after the phone restore from factory reset surprise the battery show 60% ??? I did restore 100+ app and battery show 50%, I played about a half hour and still 50% battery??? what the hell happened??? 360 camera app has to do with rapid battery discharge???
- I use advance Task Manager droidwall, light <10%, original rom only rooted
- anyway Battery discharge I think is caused by the signal GSM of my operator's.
- anyway in the night i decided to kill the traffic and by that the battery shouldn't discharged hardly over night. right?
(Q) sometimes the touch screen it freezes in games so I have to put the phone in standby and come out of standby, and then the touch screen works again ... this happens to you to?

gaming battery life

Dear nexus 7 FHD owners,
I have possessed my shiny new nexus 7 since tuesday last week, and boy am I happy with it. The only flaw it has is a dead (black) pixel in the lower left corner, which is covered by the soft button bar when in landscape.
While it is a fantastic tablet, I consider my battery life very weak. While I dont have exact numbers at hand, using google chrome to browse the interwebz drains the battery very quick imo (ill post on this in the future).
I do, however, have exact numbers on gaming. Yesterday I drained the battery from 100% to 14%, playing eternity warriors 2 for 3h14m straight, With a screen on time of 4h47m, of which an hour at the lowest brightness setting and the rest at 10-25%. Do these numbers seem to you? How much gaming time do you get on a single charge?
Idle drain seems about right, i left it at 88% when i went to bed last night, waking up with a charge of 85%. This is with wifi on in sleep, wifi and mobile network location on, currents disabled and all sync apps set to once/ hour. Though surprisingly when i tested the idle time during the day, leaving wifi off but all other settings unchanged, it drained 5% during my 6 hour school day, leaving the device at home.
I also played galaxy on fire 2 HD for 2h36m straight, draining the battery from 80-1% (i did maybe 10minutes worth of browsing in between).
I should mention that out of the box I had about 50% battery and I drained it to 1% on the first use before the first charge. I know this is bad for the battery, but it is said that most devices get their first full 100% charge in the factory right? Still though, might this have an impact on my battery life?
I'm looking forward to your feedback. The return policy ends tuesday next week, and I can return the device no questions asked until then. I will do that if it turns out my device's battery life is indeed quite the exception. I'm reluctant to do this, however, since I only have one dead pixel and I am afraid I might receive a device which has other or more flaws.
Your device's battery performance is pretty normal on the 2nd gen N7. Games seem to drain the battery the most. I get the same results. 3hrs with gaming. Worms Armageddon in my case. I usually get about 5-6 hrs od mixed screen-on use on a single charge. From what I observe Chrome will usually flatten the battery in 4-5 hrs depends on what pages you browse. The longest battery life you will get on video playback - up to 10 hrs with MXPlayer. That all on autobrightness.
I find these results a little disappointing. At least they are very far away from what is advertised. I do not know what is the biggest drain factor but I suspect the GPU and the wireless connectivity.
While transfering large video files over wifi between my nexus and an iPad it seems that the nexus uses more battery with screen off than the iPad with sceen on.

Thanks for your reply. It is really comforting that it's not just my device. Still considering a return for the dead pixel more and more, though.
RAM Hungry Games
I avoid RAM-Hungry activity. Mostly 3D games of course, drain my battery quickly when I have other services running, and the games that demand a lot of RAM at once will suck the juice out of that battery, so I usually keep it on the charger when playing demanding games.

How quickly does your battery drain when not plugged in though?
wow, such nice battery life, and complaining
Mine drained in about 1.5 days last week with a bit of usage, with wifi on the whole time. Charged from 11%. No sync.
todays results
Today my battery was drained in: 1.5 hour gaming, 1 hour chrome, 5 hours screen on time.
I find these numbers quite the disappointment.

That does seem a little low to me. I don't do a lot of gaming (Tapped Out is about it) but I have a lot of on screen time between Kindle, web browsing and Netflix. This is all anecdotal though, I haven't actually measured how good my battery life has been, it just seems to be good to me.
Are you running a custom ROM? I'm running CM10.2 and I *think* battery life got better when I flashed it. But again, I didn't measure and compare so its just a gut feeling.

I'm running full stock. My stand by time is actually pretty good (1% overnight last night), but thats probably because ive disabled most power hungry features (location, wifi off in sleep etc).
While i do a lot of gaming and battery life is expected to be low then, I expected at least 4 to 5 hours worth of gaming, since it is advertised it should last 9 hours when viewing 1080p video (which is not streamed)

Bad assumption. The hardware video decoder is extremely efficient (at 0% brightness I measured 1.28W power consumption for 720p; equivalent to 11.7h battery life).
The CPU/GPU hits thermal throttling (not enough cooling to run at full speed) at about 5W power consumption (= 3h battery life). Going from 0% brightness to 100% brightness adds another 1.05W (total of 6.05W = 2.5h battery life). So a game that heavily loads the N7, can very quickly drain the battery.

Thank you for settling this problem with actual facts! IIRC the battery capacity was indeed 15Wh, though I didn't know max. usage was 5W, I thought it was more like 3-4W.
I'm a bit curious though as to how one monitors the system power consumption. Is ther an app for that?

I'm measuring via the USB port (I built a power monitor).
The N7 also has a battery gauge chip that can measure current. The driver logs some debug info, including a current drawn value every 60s. However, that value is only the average for one second, so it's not very stable.
In a root terminal, you can run
Code:
dmesg | grep bq27541
to get the debug info from the battery gauge chip.
(BTW, that current is the current flowing into or out of the battery, not the current used by the system.)

I use Battery Monitor Widget. Among many other graphs it provides a %/h graph. I can see in games my N7 drains at ~30%/h

Great explanation. Thanks. What is then happening in Chrome? It's the 2nd biggest battery drainer for me. From what I can see it drains battery at the rate of 20-25% per hour.

Chrome is a CPU pig. Even sitting around on a web page with a single animated GIF will eat 1.8W at 0% brightness. Add in some web pages with a lot of Javascript (Javascript is extremely CPU inefficient) or not using an ad blocker (it's pretty common to to pull in ad-related Javascript junk from 20+ places on a single page and a lot of ads include animated crap) and you quickly get a lot more...

Gaming experience of Moto G

Hi guys, i want to ask some questions about this phone, mostly about its gaming experience. I know that this phone has great all-day battery life, and i also know that Moto G is a great gaming smartphone, if not the best, thanks to its Snapdragon 400 and Adreno 305 GPU. And i believe this phone is capable to handle most of graphically demanding games around Google Play Store. But my question is, what's about the battery life of this phone when playing games? I mean, how long can it survive when playing intense games without resting the screen, of course, from the full charge 100%? I'm actually quite interested to get this phone in the near future because it's affordable but amazingly good.

Well, you wont have to worry about the battery life I have played demanding games like mc4 and real racing 3, and the battery is just not going down fast at all. Like i could play mc4 for several hours, and still 30% left. Ofcourse not with the highest screen brightness. But this phone has just an incredible battery life overall. Like i could go with 30% battery in the morning, and in the evening there is still 10% left. So dont worry about the battery, in my opinion it does a great job.

It really depends on the game though. For example Badlands (a 2d game) is absolutely murdering my battery, while games from the Anomaly series that are 3d last longer. But all in all, you can expect to get a solid 3-5 hours of gaming without issue, plus the idle drain is minimal, under normal circumstances, so you can make it back to a charger an hour or two after you get your first low battery warnings.

Lg g3 battery drain issue [ Tried normal methods % have screen shots ]

Guys im sorry but i have rushed a few replies to get the 10 posts but can you please not take this down i need to know if this is legit as my money back only lasts a certain amount
Ok so i bought a lg g3 from ebay, Its legit i have tested with antutu officer but it can get really hot and battery drains very quickly when watching movies and games.
My screen usage is always above 60% but i have screen on 30 seconds and 0% bright. My phone also says that i have used like 1000 mah at 50% but it should say 1500 mah.
I have a d851 and marshmallow and use my phone only with wifi no gps/nfc i also dont have background apps
My phone gets 188 mins on gfxbench

Why should it say 1500 mah? The screen is not the only thing that drains the battery, you know that, right?
Running any benchmark will cause many battery drain. Don't do that. And that app you have to see the cpu temperature, 42º is not high for CPU. For battery it is.

What help? Get a new battery or go away from Snapdragon devices. And, the screen usage is about right, because i don't know if you know, but the screen you are staring at is 1440x2560, or 2K, which is an insane resolution, and crammed in a 5.5 inch display at 538 ppi, it will consume A LOT. And the battery is just 3AH, which seemed much, but compared to the S5, with a 1080p display and a 2.6AH battery, the G3 has the worst SOT out of the 2014 flagship lineup.

The 2K screen doesn't consume that much power. There are mods which allow you to lower the resolution, but you won't see much or any increase in battery life or performance (maybe in games it's going to be most noticeable).

Sounds like a bad battery. Quite possibly a reason why the other person decided to sell it in the first place. How old is the device that you purchases?
You can get an original replacement battery online for a few dollars. Just make sure you use a reputable vendor, like LG's official website.

Its brand new thats why i'm worried and i have downloaded a few battery checking apps and they say battery health is good.
But when i add up usage it totals lower then the battery capacity, they total up to 1000mah at 50%, when it should be 1500mah
Do you have any benchmarks i can try so i can see if its working right or its just me.

Oh so it's a brand new LG? How many hours of screen usage are you getting, what usage (web browsing, checking email or playing games?) and with what period of idle time.
Don't trust the numbers in the battery stats, especially in a new ROM. They are supposed to get better over time but I've found them to be wildly inaccurate even on months old ROM. I haven't really found an application you can benchmark accurately with.
But you compare with other (real) results on the foruns and rather you get the hang of what's the normal usage you should be getting out of a good battery.
Did you make a day without running any benchmark apps? What is your SOT? Standby time? Do you have location,wifi,bluetooth,NFC,mobile data on?
All of this matters. You shouldn't start right away with "I have problems with my battery" if you are running benchmark apps. Benchmark apps drains battery!
Wait a few days without running that apps and see how it manages. Another thing. The battery stats, the mah usage, not all of the things appears in the default android battery stats. And another thing, the battery value (the percentage of the battery), it is an approximation. Sometimes it could go up without charging, it is because it detected that has a wrong value. You could try charge your phone to 100%, usage it normally until 0%, until it turns off. Then charge it again to 100% and use it normally (don't discharge to 0% to many times, it just hurts the battery).

Streamed from the internet with at least 1h10 SOT, that is not bad. That is almost 4 hours SOT. If you have 1h12 minutes SOT, that is 4 hours. It is good.

Oh yeah, considering you even streamed the movie, it's signs of a good new and healthy battery. 3 hours of SoT with internet browsing is quite the norm, and 4 hours is on the up side.
I can barely get to 2 hours of SoT with my now aging battery.

It's not about the software side of things, it's about that my battery is old now, and that's why happens to old batteries, the just deteriorate.
Thankfully the LG G3 has an easily replaceable battery, and I have a replacement waiting for me. Not getting a phone on which you can't remove the battery..
And never found those apps like Greenify to really work, at least in the last few years of Android. The OS seems to be doing just of a good a job and I see no improvement in battery life. Maybe they help in cases with poorly written apps that are draining your battery in the background, but I don't see why would you use such a software in the first place.

There are other things. Try to disable assertive display. You can disable logd. Turn of VoLTE. I use greenify because the aggressive doze.

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 Samsung Galaxy S8+ before depleting the battery.
Then, drop a comment if you have anything to add!

4% to go and at 6 1/2 hours. This without power savings.

I usually get 5 to 5,5 hrs sot . it depends on usage but never dies in day usage.

I'm averaging 5.5, sometimes near 6 lately. Not bad for stock.

Amazing battery life on the s8+
Battery life has been a bit inconsistent. Usually I get around 4 or 5 hours screen on time, though honestly my habit with all my phone Shas been to charge them whenever possible. If I'm driving, I set it on the mount and plug it in. If I'm at home or work and not using it, I plug it in (or in this case set it on the wireless charger). But I was fairly unimpressed with the S8+ battery life.
Yesterday and today, I turned on the medium battery power setting. It seems to have increased my screen on time dramatically, but I'm also at home and on wifi.
Medium decreases screen brightness by 10%, sets resolution to FHD+, underclocks by 30%, and turns off the AOD. Of these, the only thing I miss is the AOD, but it also seems to make the most difference in battery life.
Either way, my battery life today is much better. So far I've had almost five and a half hours of screen on time and 54% battery remaining. That's all surfing the internet, posting here, texting my wife, taking a few photos, and a little Facebook. I'd say that is fairly impressive.
I'll see how the battery holds out Monday when I'm away from wifi, driving through varying cell tower coverage areas. I'll also check how it is if I turn the AOD back on. I do like the AOD.
Really good for a stock rom
Bat Rom & Noto.
Could of got to 10hrs but was playing with themes which require reboots.

Do you notice any decreases in performances with the underclocking? Or are things still fairly snappy?

I don't notice any performance issues at all with it underclocked. But I don't do any gaming either, so that may be an issue for others.

On wifi or LTE because it seems impossible to reach those numbers for me.
