Battery drains a lot with playing games? - HD2 Android Q&A, Help & Troubleshooting and Genera

Hi,
Is it normal when you playing a game 1 percent of the battery goes of after 100 seconds?
I thinks its not. I'm using the [19 FEB][RAM HD] imilka's RAM Desire HD v1.0 [A2SD][K:rafpigna 1.7][crazy fast ]
With kernel 1.9 OC
Is this normal or is this rom crappy?
Its froyo 2.2.1 is 2.2 better for the battery??

That doesn't sound too bad. That would give you two and a half hours game time, which with the large screen, and a processor heavy game, it seems reasonable,,the hd2 after all has a fairly underpower battery for its specs.
Be sure and kill all unused tasks, maybe switch data off and 2g only networks on, wifi off, should all help....a bit

Does the kernel also mathers?

No idea. I would imagine it does some, yea, but I'm totally noob re:android, so it would be a guess.

dont blame any ROM....may be you have your wifi, gps and other things on everytime......i suggest u too avoid task killer

[DISCUSSION] Battery life with overclocking is epic!

Only had the phone for two days so this should improve even more:
overclocking to 1.4ghz, under clocking when screen off to 0.3. 9 hours screen off, didn't lose a percent, still 100 on desire Z. EPIC!
thats good to hear ! Cant wait till i get my hands on it! damnit ! 5 or more days togo
Did you have any other functions enabled? 3G/WiFi? Sync'ing with FB or Twitter apps? Anything like that?

how many hours can you get out of it when you are using it throughout the day, e.g. email, internet browsing, twitter, bit of music and phone calls? using data and wifi?. Im on my 5th day and averaging about 14 hours, hoping that the battery hasnt settled yet, otherwise my hope is for the NAND being hacked and roms for optimal performance!
Do you actually get more real-life performance out of the overclocking (snappier menus, faster app launching), or the only place where it shows is the benchmark? Is Sense faster, or is the difference not visible (0.8 vs 1.4)?
On the other hand, underclocking could be really useful to preserve battery. But doesn't the processor underclock on its own when in standby (by design), do we need to use 3rd party apps?

contrary to what you should expect,
overclocking this SoC just hightens the clock's max roof from 800MHz to 1GHz, 1.2 or 1.4GHz, not the "permamnt" MHz count,
because it auto-fluctuates and adapt depending on usage
AND with the SetCPU app (which I assume JupiterDroid is using),
cycles per second can be optimized even more.
The phone won't go up all over the way to 1.4GHz when idle, but will maintain a very low cycles per second clocks, thus improving battery life
Here's my experience w/ battery life and overclocking the Desire Z (for today).
I only have it set to overclock to 1GHz and I have typical SetCPU profiles to underclock to 245MHz when not in use.
My phone has been off the charger since 9am (5.5 hours) and is sitting at 92% battery power. This includes permanent connection to WiFi (no sleep policy), receiving updates to email/gmail and some text conversations with Trillian and a 15 minute email (composed w/ keyboard).
Compared to my old HTC Hero (Running VR 1.5.0), this is a huge improvement, though with VR 1.5.0 I could run JuiceDefender & have similar battery life with the right profile setup.
Yup I even notice better battery life in actual use. My friends were running youtube and doing web searches like crazy on my phone last night + games for a good 5 straight hours and the battery was holding up well.
I've got to say, the battery life on the Desire Z is outstanding... 18 hours with light use and battery still @ 92%!!!
What about 1GHz core compile?

are you using set CPU and overclock?
Is anybody getting time without a signal percentage in the cell standby item in the battery usage? Im getting 12% sometimes more and im getting about 14 hours battery life with moderate use! I dont feel im getting the best out of the battery and worried this might be part of the issue!
Hi guys.. sorry for the novice post.. i have had my Desire Z for a day and am interested in overclocking it - but
a) are you saying it possibly INCREASES battery life?
b) is the speed diff noticeable in day to day use - or just benchmarks?
c) How do i overclock - what is SetCPU and how does it work?
I don't think my battery has settled yet .. I hope not anyway, and I just (temp) rooted and overclocked to 1Ghz last night, haven't tried higher yet because I feel like my battery is kind of just disappearing so far, none of this epic "all day and then some" stuff some people are reporting. I think it may be that fact that I've been using the device pretty sporadically so far, and it hasn't had a chance to settle.
Also "cell standby" seems to be using a lot of battery, and I'm thinking that's because I'm unfortunately in a spot where I get extremely poor to no coverage most of the day. So I'm thinking the cell radio is using a lot of juice trying to get that 1 bar I sometimes see here. There didn't seem to be a way to easily disable the cell radio without disabling wifi though, until I found this "airplane mode wifi tool" on the market which I just installed.
So now my cell radio GPS and bluetooth are all off while wifi is on, hopefully that will make a difference. I'm wondering if using 802.11n is more draining than 802.11g also I know both my router and the desire z support N but "network info II" reports I'm only connecting at 65Mbps, while my laptop connects at 150Mbps.

I don't think there's any way overclocking can actually increase battery life, but managing CPU speed with SetCPU seems to be more effective than the default behaviour for some reason, so the fact you're overclocking when using it but underclocking when not using it results in longer battery life. I'm pretty sure it does regulate the speed automatically without setCPU but maybe it doesn't clock the CPU down to absolute minimum by default when the screen is off?
Anyway the noob friendly guide to overclocking by JD is on the forum with an [INSTRUCTIONS] tag.. I can't link to it apparently since I'm a noob.
Edit: Added link ~TheRomMistress
Thanks guys. Main thing i'm curious about is whether i just install SetCPU or i have to "root"
Yes, SetCPU needs root access.
Still trying to figure out how the OP is underclocking to .3 using SetCPU.. Lowest I can go is 245..
Unless I'm an idiot and completely missing something.. I'd love to turn this phone way down when the screen right off. As it sits, I'm lucky to get a full day from a fully charged battery.

Your mileage may vary
You can check by yourself and then uninstall if you are not satisfied (or just reboot and changes will dissappear, since we don't have permanent root yet)

Is this really a thread. You use your phone nonstop and wonder why your battery lasts the way it does. You cant compare a psp to a nexus s. Close this thread. You want better battery life stop hogging the phone.

My battery lasts me all day. I play n64oid for an hour a day during lunch at work. That drains 15% to 20% during that time. So yeah, that sounds normal.
Its not a console, built only for games. It has other things running all the time. Also, my old PSP maybe got 5 hours, you must have an extended battery.
Sent from my Nexus S using XDA Premium App
yes this is normal
i can burn through the 100% charged battery in 3~4 hours just browsing the internet alone
the WiFi or 3G is what eats all the power, same goes for the SAMOLED
other devices last even less time, using HTC Desire and similar devices i can drain the battery in 2~3 hours
i always carry extra battery packs with me, i'm a heavy duty user
So, to your answer, no, it is not unusual
High end 3D games also uses a lot of power in the CPU, GPU, SAMOLED and if you are playing online like WOW online for Android, then it will go up even faster.

[Q] Battery life, compared to the Galaxy S
Hi guys,
I used to have a Galaxy S device, and recently purchased a Nexus S, and gave the Galaxy S to my wife.
I assumed that, given the fact that these two devices have a very similar hardware, the battery life would be somewhat similar in both.
However, this is not what I have experienced at all. I basically reinstalled all my apps and home configuration in the Nexus S. The only difference being that I'm using a darker wallpaper now (which is supposed to improve battery life.) The rest is pretty much identical - I basically restored all data from my apps using Titanium Backup (not the system data, evidently.)
I have noticed however that the Nexus S spends a lot more battery than my Galaxy S, especially when the phone is idle. I have everything turned off (GPS, NFC, 3G and Wi-Fi) just as I did with the other phone. Even on Airplane Mode the Nexus S seems to use a lot more battery. Leaving the phone on Airplane Mode at night would barely consume any battery at all with the Galaxy S. The Nexus S does take some hit though.
The battery life is still not a bad one. Especially when compared to LCD phones. However, the Galaxy S is significantly better with stock 2.2.
My question is: Why could this be? Is it because of Gingerbread? Or am I missing something?
Thanks guys!
it's quite the opposite for me
my previous phone was a SGS and it chewed more battery than the SNS

Try to deactivate the GPS and Wifi if you do not use them. You can also use some apps to deactivate 3G access.
I wish Samsung produced higher capacity batteires though.

Was your SGS on 2.1?
I did notice that on Froyo (2.2) the SGS had a much better battery life than on Eclair (2.1). It really made a great difference.
But my SGS on Froyo is consuming a lot less battery than the SNS on 2.3. Especially when the phone is idle (both with everything turned off and set to GSM or even on Air Plane Mode).
So I was wondering if this could be a software issue.

Same with me. I came from a Vibrant, and no matter what ROM I used, I'd lose around 8-15% of battery while sleeping.
With the same settings, and apps now on the Nexus, I lose 1-2 percent while I'm sleeping.
The idle is a lot better for me with the Nexus, and I lose a little bit less while I'm actually using the phone as well.

For me it's exactly the other way around. I assume your Vibrant was on 2.1, right? Cause in 2.2 the SGS does much better. And this is what I would lose: 1-2 percent when on airplane mode for an entire night.
Mind sharing what your config is? I'm on 2.3.3 + Netarchy 1.2.7

I was on 2.2 on the Vibrant. I was mainly using the Axura and Trigger roms.

Go get it exchanged and if it keeps happening, then it's your usage that you need to deal with by getting more batteries or keep it on the charger whenever you can.
I read a lot of threads and posts about battey life on NS and the problems of 100% charging, and most of people declared that the NS has a better battery life of all i9000 series or S series.
Maybe a nokia would suit better, days of battery

So wait - your PSP has both an extended battery and an extended external battery and you're surprised it lasts longer?
The Nexus S has a 1500 mAh battery in it. The PSP extended is a good 3600 mAh, and external packs can be 4200 or more. So that's 1500mAh for the phone and 7800 for the PSP. The PSP has 5.2x as much battery to power it, so it's logical that it'd last longer.
The phone's also a lot smaller and running power hungry radios for network connectivity, an OS to manage everything and misc. background tasks in addition to whatever game is running.

You're brave saying this in this thread. Most of us now thing you're an idiot...
My Nexus S went 33 hours before last charge. I am a light user though.
To check how you're does, don't use it for at least an hour one time, coming off charge. You should only lose 2-4%. Then check battery usage and see what's taking power when the phone should be doing very little.

[Q] Just want a few quick reminders on Mytouch 4g

Getting one of these this week to try out the whole android craze. So I already know it will have a rather crappy battery life even with better kernels and roms, but is there a way to generally underclock the device to squeeze more juice out of it? And yes, imagine that, I'm NOT cpu speed crazy.
Camera, like most HTC's still sucks for still pictures, correct or wrong? Unless you're a human tripod, they will come out partially blurry and shooting while moving or moving objects sucks. And that annoying whirring zoom mechanism...
Other than that, any other particular quirks and perks I should know about?
Well how much battery life do you look for in a phone per day? Because with heavy usage I can squeeze 12-14 hours out of man and yea camera is blurry with video if there's movement (I/e went to a concert can't see much of anything in the video) but there's many good developers and such out there especially for this device to increase performance and battery life such as faux123's lV kernel, it's low power but you can still over clock to 1.8 ghz and can underclock at 354 MHz which is great for saving battery as you can set up CPU profiles in an app called setcpu so overall there's not too many issues we haven't worked out for this phone its pretty much a great phone for doing anything
Sent from my HTC Glacier using XDA Premium App
The latest GB Sense camera is the best by far, still a bit of blur with motion but the image quality is easily the best out of any other ROM. When coupled with faux's lv kernel you can get anywhere from 15-48 hours out of it. It's a good phone for an average user, an amazing phone for someone willing to learn.
Willing to learn for sure, but primarily want to have an android phone in case some app comes out that I feel I need. Else I'm usually about business-level productivity and longevity and these almost always translated into candybar qwerty w/ good power management (like my Nokia E72- phone has a ludicrous battery life and lasts me 3-4 days w/ some texting, some calling, some music and net use). But are there any affordable android ones like that, that aren't utter crap? No.

My best ever was 3 days and 15 hours on a single charge with light to moderate usage over a weekend. This was on CM7 with the stock CM kernel. In my experience the best way to save battery is be connected to wifi anywhere there is wifi because your phone will not be constantly scanning for a better data signal.
Or to turn off all data unless you gotta use it. Still looking for a decent rom for this thing....

In terms of battery performance, RoyalGinger is the best rom out there!
I use Elite Sense 2.6V(unthemed) and battery life has been stunning for me(245min & 900Max), the performance is still rather quick at 900. I use 3D games, music, friendstream, phone, browser, 4G, and I still get through the day. I do turn off b/g data since I sync everything manually when I feel it's needed, or I need to use the market for app upgrades and whatnot.
And do sim contacts show up alright on Elite Sense? Royalginger failed me with sim reading, so as bare-bone as it is, don't want to use that one.

What sort of battery drain do you currently get on standby? Can you tell me the reading in ma from CurrentWidget? If it's 3-5 ma with mobile network/wifi/bluetooth etc on and 2ma in airplane mode then you're fine,but if it's higher it can definitely be improved.
If you don't plan to use mobile internet connection then disable 3G and turn 2G mode only. Turn off as many widgets as you only can, disable Location Service and auto sync. Install apps on phone memory only.
Also Dorimanx kernel is a hell of battery drainer, use another one like stable Tytungs etc.
Use dynamic/powersave CPU governors or use CPU speed profile apps like SetCPU and make several profiles for it.
This is only a few of tips we can give here.

Well the apps I use to reduce my battery drain are JuiceDefender and SetCPU. Set the profiles to be 245-576 Mhz when screen is off (smartassv2) and whatever else you like when screen is on. I never had any overheating problem with Tytung's kernel though. It was the most stable and just as fast as Dorimanx's kernel IMO. Still, using ICS now so I can't really judge about the newest versions of each of them.

I think his kernel is the same in battery drain over any of them. Ive tried them all. If anything, seader_r9 was the best and it was only a small improvement. My battery life is pretty short, but im a HEAVY user. Constant web browsing, constant text messaging contant GPS. And it lasts for the majority of the day. Now i have an .sh script which helps tweak the smartassV2 settings. I get about 110-200ma drain when doing simple web browsing or replying to a text.
One must also keep in mind that the ROM has a major part in battery drain as well. I heard from many users on here that MIUI has the best battery life. All in all i think any kernel you choose will have reletively (i spelled that wrong -.- its still early ) the same battery drain. It really comes down to the amount of use your phone has. But as stated before, turning off data greatly saves the battery as does turning down the screen brightness, fyi, automatic brightness sucks battery life too. Plus android does a horrible job polling the light sensor -.- it shouldnt take an average of 3 seconds to get the changed light value..
Theres not much 'tweaking' you can do to give you like an hour extra of battery life. Our batteries are only 1350mah batteries and thats really small for such a huge screen. My Touch Pro 2 has a 1500 and a much smaller screen. There are a lot of good aftermarket batteries on ebay that you could get which would extend your running time.
thanks guys, im gonna give a shot to tytung kernel, but im also gonna take a look to the aftermarket baterys
Typhoon rom support undervolt so if your phone is gettin' hot I suggest you to tweak the voltages as explained to original thread first page, it makes a big difference compared to stock.

Good advice here. There's a lot you can do (as already advised) but always some performance tradeoffs. The standard HD2 battery is only 1230 mA... not 1350. Smartassv2 in DM's kernels is excellent for performance and settles down nicely in standby - but it will pull-on your battery when used. There's no substitute for keeping a few extra charged batteries around (when you need them), along with AC & DC chargers + cable, in a small carrying case.

There's no substitute for keeping a few extra charged batteries around (when you need them), along with AC & DC chargers + cable, in a small carrying case.

You don't need to use dorimanx's latest kernels, his stable kernels in fact do a better job at not overheating and have only 2ma drain on standby. I know 5.9, 6.3, 6.4d, and 6.9A (ics hwa) give a great battery life.

Wow, in standby im on average around 7-3mA with the occational spikes when receiving texts or messages over wifi. And when on data its about the same, just not as often in the 3ma range.

Which apps are running in the background? People constantly say that task killers make no difference yet whenever I've opened something and haven't killed it I get a higher battery drain than normal.
Also, use JuiceDefender and SetCPU to lower the drain.

Uploaded some benchmarks and battery stats.

A few days of using pure stock, I have made a folder containing screenshots of my benchmarks and battery.

How do you get such a good battery life? Please tell us!

That's impressive. What kind of screen on time were you getting with your prior phone?

I had a Sony Xperia Z3+ and when it was pure stock I would get 3-4 hours but that was with a disadvantage, I had to tailer myself to not game or use it heavily as it had the notorious SD810 and would easily hit 80°c while browsing and playing simple games. When a kernel came out SOT didn't improve much just user ex and heat. So yeah this 3T tops it in all my main areas sound, camera and can use it however I feel. :highfive:
First charge.

I haven't done anything, using dark theme's where possible but other than that it's just my daily usage but constantly. Today been using it on YouTube, Tidal streaming, browsing and playing pinout. Sitting at 25% 6H 48M SoT. I f**king love this phone. Just wait till I root and get the tweaks back on
Did you even use your phone? I bet you just enabled so the screen doesnt turn off and placed it on desk.. Thats unfair if you did that as the cpu is running on low mhz all the time
Some people get good battery on every device and some people always get bad battery. I always get great battery on all my phones and this one is no exception. I've hit 10, 11, and 12 hours screen on time and have not done anything to save battery.

No I used it. Why would I "just sit it on a desk"?

To hype up and get attention. I really dont understand how can only you get such good battery life while the rest of us are having significantly worse stats
I believe you tho, 3400mah is not a small battery plus you posted a lot of stats /graphs and details about your battery usage

Yeah because I come on XDA for attention
Temperature changes wouldn't happen if it was having a holiday on a desk? Or high constant WiFi data if I wasn't streaming music.

People do a lot of stuff here just to get likes xD
I get 7-8 hours sot, using my 3T as any other phone.
I used to get aswell 7-8h on the Oneplus One, constantly on WiFi (with LTE it was worse, 5h SoT). Mainly using chrome, tapatalk, flipboard. (no games).
Now on the 3T its pretty the same (7-8h SoT on WiFi).
ofc games will drain it alot more. its depending on usage.
you also get different results when ure on Enterprise WiFis (high dtim interval, authentication system, etc.), then your WiFi could consume much(!) more battery.
at my work, even 4G takes less power than WiFi. While at home, wifi takes nearly nothing (8h idle on wifi = 1-2% max. drain)

Make a good point about the WIFI. My Asus has this option, I enabled when I got it.

I get your point, but this is not the case. See my print screens in this thread -> http://forum.xda-developers.com/one...ife-sd821-400mah-t3505786/page10#post69935470
Its helluva device (the combo of HW and well optimized OS).

Dsl-ac56u been going strong but want to upgrade soon.
Pretty good battery here. Getting 7 hrs most times although my s7 edge exynos would give me somewhere from 5 hrs to 6.5 hrs sot, O3T SOT is amazing.
Hi @LMcR92 bud very good scores and stats
