N900 Battery Saving?

ok, so had my N900 for a little over a week now and overall I'm pretty impressed. Great phone, but still very much a work in progress. One of the main issues I have at the moment, other than no turn-by-turn navigation (sorry, had to mention it), is the battery life - or lack of!
On an average weekday I use the phone to send a few texts (no more than 10), scan the news sites (no more then 20-30mins total) and catch up on my RSS feeds (again, no more than 20-30 mins total). I'm not using the media player at all and I may make one or two short calls.
Bottom line is that I'm struggling to get more than 6 hours battery life out of it. I know smart phones are thirsty, but I don't even get to listen to music on my way to or from work!
Here's what I've already done to reduce battery consumption:
Removed active widgets (such as ForcaWeather) from desktops and replaced with web shortcuts.
Reduced screen brightness to 2 bars
Disabled GPS & Network positioning
Disabled IM
Disabled Bluetooth
I've heard some mention reducing the amount of active desktops, but I think that kinda defeats the object of having a N900. May as well buy a lesser phone if you need to strip out all the functionality to get though the day. I'd be satisfied with 8-10 hours medium use. At the moment I'm getting around 6 hours at light use - got to be something I'm missing.
Any ideas?

Hey,
Also i had the same problem. Closing active widgets wont help. Re-flash and clear your device. Then install only important apps to your phone.
Dont use active widgets.
Dont use two running applications at the same time.
Install system info widget. Always try to keep your RAM usage less than 140MB.
Hope youll get it...
Good luck...
(Any way i had enough of these battery issues and i re-flashed my device and now im running it without any applications.(But have the in built apps) . Now phone is awesome. lol )

OpenCL How to use both GPUs in battery saving mode

Hello everyone,
Currently I'm developing a software using OpenCL under OS X 10.6.4.
The galaxies (n-body) application provided by Apple is able to query and use both the 9400M and 9600M GT of my Macbook Pro. The interesting thing is, it can even do so in battery saving mode i.e. when the 9400M is the display device and the 9600 should be turned off. Looking at the XCode project and source code it just does:
return_value = clGetDeviceIDs(NULL, CLDEVICE_TYPEGPU, 4, mdeviceid, &count);
To get a device count of 2.
My Makefile based project also links with -framework OpenCL. Executing the same line of code yields just the 9400M though.
Since the NVidia samples show the same behaviour I guess there is a difference in the way the XCode project is set up.
Thanks in advance for any hints!

Just found out the following:
It is possible to utilise the 9600 in battery saving mode for calculation purposes.
All you need to do is to create an OpenGL context and iterate over the virtual screens like so:
GLint i = 0;
CGLContextObj ctx = CGLGetCurrentContext();
while(CGLSetVirtualScreen(ctx, i) == kCGLNoError) {
i++;
After doing that, a call to clGetDeviceIDs yields two gpu devices:
unsigned int count = 0;
cldeviceid mdeviceid[32];
clGetDeviceIDs(NULL, CLDEVICE_TYPEGPU, 32, mdeviceid, &count);
printf("Found %d GPU devices...\n", count);
Test environment:
Macbook Pro (first unibody, w. 9400M + 9600M GT).
OS X 10.6.4
Explicitly settings the pixel format attribute to allow for offline renderers wasn't necessary in my case.
Unfortunately this solution sounds rather like a bug than feature, so Apple might 'fix' it in the future.
What is more, being required to carry around an OpenGL context might is not possible in every case.
Would be nice if we could just decide which card is used for display purposes in high performance mode, then there would be no reason to fallback to these kind of workarounds...

GreenPower battery saving app and "my Xperia" service

I have recently migrated from an iPhone to Sony Z1 on EE, and I have been pretty happy with this transition.
The only thing I have noticed is that the Stamina mode was not performing as I was hoping, so I downloadd a third party battery saving app called GreenPower. This app has significantly increased the battery life of Z1 to the point where I'm only charging the phone every few days.
The nature of this GreenPower app is to automatically disable WIFI and Mobile Data while the screen is switched off, unless you specify a whitelist of apps to keep data enabled if the apps are active. Unfortunately, this mechanism stopped "my Xperia" service from being able to locate my phone.
What is the "exact" mechanism in which "my Xperia" service locates my phone? Is there a process on my phone that polls, or push from my Xperia service?
Any suggestions on the list of processes to add to my white list of apps in GreenPower? I have added "my Xperia" app to this list but this did not help.

MyXperia needs the data to be on or wifi, third party apps will create issues with other apps, there isn't a way around it, other than uninstall such apps.

Missing Battery Saving Mode

Hi, friends!
I was fiddling around with my 9360 and I realized that I don't have the Battery Saving Mode option. I know that I should since I'm running 7.1.0.336, right? I don't think that I did anything wrong in installing the OS. How do I get that option? Is there something I need to do?

It is the 7.1.0.342 that has a Battery Saving mode for 9360 and unfortunately, its not available with Globe as our Carrier is "not so" updated with OS.

No hiberation mode or battery saving mode in HP Steam 7 tablet

Hi,
There's a problem with my HP Steam 7 tablet where I can't enable power saving mode for some reason. I click on the power button but the battery will drain off in a few hours unless I have to manually shut down the tablet which is annonying. Is there a way to fix this issue? Thanks.
This question was solved.
View Solution.

We had a good size thread about it all here but I cant seem to find it, so I'll give you the short version. 2 things are known to prevent the cpu from sleeping and drain the batter when the tablet is in sleep mode.
One is the audio driver, the workaround is to keep the volume at ZERO (This is equivilant to mute).
the second is bluetooth/wifi (There is an explorer process that is getting stuck on), the work around is to turn airplane mode on when you arn't using the tablet.

Battery saving config for luminas on WP8.1

Anyone happen to have one that does more than this? Love the 1520 but battery life is subject to mileage lol..
ringtones and sound:

play a sound for:system alerts
email+accounts:
download new messages: hourly
sync msgs and contacts: every 2 hours
lock screen timeout: 1 minute
wifi:manage:uncheck both auto connect to hotspots and send info
NFC: off
battery saver usage: everything off except LINE, battery saver, internet explorer, skype, onedrive
turn to 'not allowed' : cortana, calendar, store, etc

brightness: auto
advertising id: off
keyboard>suggest text: unchecked
advanced: uncheck improve suggestions by sending info
display: sunlight readability off, battery saver brightness on
touch: sensitivity normal, wake up off, navigation bar vibration off!
glance: off

With normal use the phone should easily last a day, generally more. There should not be any need to switch off anything unless for instance you are in an area where cellular reception is bad. I'd switch off data and probably select 2G only as thatwill generally be acceptable anyway.

IOS 4.2 has battery saving feature but is up to network to implement it...

http://www.appleinsider.com/articles/10/11/30/ios4_2_supports_new_technology_for_reducing_networkcongestion.html
This is realy interesting and a feature some would be willing to get...Now only if carriers in the US can impliment it...

I would think Apple added this capability with AT&T in mind since its the only exclusive carrier in the US for now...less network congestion means faster load times too!!!

Verizon iPhone 4 Battery Draining issue (continued)

This is not a question or help topic but more of an announcement. Here's my story:
I preordered the phone on it's February 3rd date and recieved the phone on February 7th. I did as Apple instructs when you get a new idevice (drain the battery down till it dies then recharge it to 100%.) I did that and began to use it, and keep in mind this was not heavy usage at all. I didn't have any app store apps installed at all, I set all settings in the phone to the best configuration for battery saving (truning off push notifications, turning off location services for apps you do not need, no bluetooth, no VPN, brightness at 33%, ect.) Now I thought the battery was strange as I had made my first phone call on 100% battery and it was a 5 minute call. I kid you not I lost 10% battery from one phone call. I thought that was rediculous so I went into my local verizon store and had it replaced. I did the same as I did last time and let the battery drain till it died and filled it to 100%. Tried the phone out and still had the same issue. I went back in and got my 3rd iphone 4. Did the same steps as before and drained then filled it. Yet again, I still had troubles with 3 phones in a row. I cantacted apple and got in contact with an apple engineer named Andrew. He sent me a file that they created that monitors what all is being used by the battery and monitors background processes and applications. I let that run for 24 hours and sent the battery loggin file back to Andrew. They reviewed the log and gave me a call the next day. They told me they did find some very significant battery draining and advised me to go to the nearest apple store ASAP and have the phone checked out. I drove 2 hours to the nearest store for them to just tell me the phone is fine (yotta yotta yotta) and they did a hard reset and restore on the phone (which I could have done from home on my computer and save the gas they made me waste driving for a total of 4 hours!) I tried contacting Andrew agiain but Andrew did not reply to any email sent to him nor return my calls. I got the point that he didn't want to deal with me anymore so I then decided to go the Verizon route. I called Verizon tech support and was transferred to a teir 2 representative. I told her my story, how many replacements I had, and how bad the battery life was. I told how my grandmother has an iphone 4 and I sat down comparing the 2 (battery life wise) and she chewed me out saying things like, "How dare you compare AT&T and Verizon!" I didn't want to listen to her chewing me out so I hung up. The next day I gave apple a call once again and they told me things I had already heard several times so I hung up. I called Verizon back and they said ok let's send you a replacement phone. Well the replacement phone came and wouldn't ya know it? The phone still had the same problem and on top of that they only sent me a phone. No box, no headphones, no USB cable, no charger. I called Verizon about this and asked why they only sent me a phone and they said, "Well you get to keep the phone but we want the other things back. The box, headphones, charger, USB cable, ect." I told them no and that they could have their refurbished phone back. This phone was not even refurbished. the reason I kow that is because it had someone's name written in the phone and it was still on 4.2.5. Had it been refurbished they would have done a fresh restore and update as 4.2.5 was deemed obsolete. That was very insulting in my opinion. So I sent that back and contacted apple one last time. I asked what other options I had as I was stressed and did not want to hear the same things I have already heard. they said they could send me a new phone free of charge and have me send back my current phone. I agreed to give it one last shot but I am still not confident that this phone will be any different.
Now that's my story. Now let me go into a discussion. I have been doing my own litle "investigation on this phone to see what is making this phone drain so bad. I took a look at a report from iFixit.com and they revealed some pretty interesting things built into the Verizon iPhone. I am not going into detail about it but you can google it and see for yourself and read the article about the components. They built the phone with not only CDMA tech but also GSM. Now what purpose would that serve? Honestly? That is a big battery drainer right there. Secondly, they found that the phone contained a different model battery that was lighter and had less capacity than the GSM version of the iPhone 4. That's a second red flag. My mission right now is to get Apple's attention that these phones do indeed have aproblem and they need to be looked at because this just aint workin'. I have had several replacements done (all have the same issue), several thousands of people are reporting the same results with their battery on the web, and Apple chooses to ignore it. Something needs to be done and I encourage any Verizon iPhone user to take action and make this issue known. I have a website with contact information of people who work high up in the chain of Apple along with Scott Forstall's contact info. Go to http://idevicesupport.webs.com/apps/blog/show/6441029-update and find a contact you like and call it and deman that apple investigate these phones. We can get this issue resolved if we make it known. Don't be mean or nasty to them. They are very nice people but at the sametime don't let them talk over you. Make your voice heard. Thanks for listening guys. Take care. - Joe

IPhone4 Battery life: The report you all have been waiting for!!!

Hello fellow iPhoners,
I'm a proud owner of an iPhone4 who have been getting sporadic battery performance for a little while. One day I can get 5 to 6 hours of usage while another the phone can barely make it past 4 hours doing the same things.
Therefore, I decided to start my own observation and document my findings regarding why my iPhone 4 can give me good battery on some days and terrible in others.
Intro:
Now I'm sure all of you have read all the typical battery saving tips such as turn off fetch, dont game too much blah blah blah. Well, I wanted to know what is the real world impact do these things really do on battery and how much better is the battery life with them off.
The following are always ON for me: Wifi, notifications (no push or fetch), edge (I never use 3g - too slow anyway).
Screen brightness is set in the middle so IOS decides when to raise or lower it. Actually IOS seems to only be able to brighten the screen if you say, walk from a dark to well lit room. The reverse seems not possible. You must put your phone to sleep and wake it in order for the display to dims.
Keep in mind I typically get between 6 to 7 hours of medium usage. But I set out to find why do I get
less than 5 hours in some cases.
Observations:
1. After placing iphone in charge at night, went to sleep, woke up in morning to find that the iphone was at 65% and losing power while still PLUGGED IN. I had to unplug and replug.
2. Sometimes iphone will get real hot while I'm not using it. Even after a reboot, it would continue to remain hot and drains battery.
3. Observation 2 (above) has only happen 2 times unexpectedly.
Answers to Observations:
1. I no longer plug my iPhone on certain outlets to charge. I have come to realize that all outlets aren't equal and while some of them will charge up the iphone very fast, it tends to lose that power very fast also which would contribute to the days where I barely get 4 hours out of it. Thus I recommend plugging your phone into a wall outlet and not via an extended outlet. Also using USB to power it up via my PC doesn't provide the best battery life either.
2. When my iPhone4 gets hot on standby, I know the processor is still running(very fast) which to me means an app is still running even though IOS4 is SUPPOSED to only SUSPEND apps in the background. However, we dont know and assume apps that have not been updated to OS4 simply get closed when we press the home button. Well, I have never updated my AP Mobile app (because the latest update *****) and I feel like it may be one of the culprits that render my phone a hand warmer. However, I also feel like Call Of Duty: Zombies might be another culprit as I always have used one of these apps when the phone keeps getting hot.
Now of course I won't blame these apps solely as I also feel IOS4 itself IS buggy and may be the bigger culprit. Sometimes X'ing out everything in the background tray solved the hotness problem, sometimes it doesn't and the phone will keep on dropping in battery until it dies.
Now I always wondered how did apple arrive at their claim of "up to 14 hours talk time on 2g" and "up to 10 hours of internet use on wifi" when I can barely get within that vicinity. While I have been able to figure out how I potentially could get 14 hours of talk time on edge, I still can't see how 10 hours of internet is possible on wifi because... wait for it... WIFI as I have just discovered is one of the biggest slow battery drainers.
It's true. According to my observations, with Wifi TURNED OFF my iPhone will drop 1% of battery every 7 to 8 minutes of light usage such as reading a book via iBooks or reading jokes on iPhunny. If you do the math, 7.5 x 100 = 750 /60 = 12.5 hours of light usage. Remember this is with wifi off and on edge only.
Now with WIFI ON and about 2 notifications for apps, doing the same exact thing, I get between 4 to 5 minutes per 1% of battery. One may say, that's not a huge difference, but it is sizable when we do the math, 4.5 x 100 = 450 /60 = 7.5 hours of light usage. This falls in line with my usual 5 to 6 hours since I tend to play a lot of games as well, which required more battery usage than say just reading a book.
This also hold true for when the phone is on standby which drops 1% every 40 to 60 minutes with wifi OFF. With wifi ON, it was about half the time.
When I turned off notifications completely with wifi still ON, I failed to notice any significant improvements to battery life as a whole.
QUESTION:
Since I'm not an apple engineer, I was wondering if any body knows an answer to this: I'm aware that the iphone - when wifi is enabled- will keep on scanning all the time. However, I was under the impression that once it FINDS AND CONNECTS to a network, that it should STOP scanning. I mean, why should it keep on scanning if it's connected to a network already?
But, I feel like the reason why battery life is so different with wifi ON is because it keeps on scanning no matter what. So there's always this tiny process running all the time.
Conclusion:
Despite over blown antenna issues, iPhone4 is a great device with great battery life to boot. The question is whether you are fine with say 6 to 7 hours of usage? If you would like to get more, remember to use a good outlet, turn off 3g if you dont need the data speed since phone calls tend to drop less on edge anyway, and turn off wifi when you dont really need it. Those remedies can add at least 2 extra hours of usage for you.
DISCLAIMER: Please all the above is only my opinion based on my own observation of my own iPhone4. I'm no professional techie or engineer. So no flaming or raging.
Thanks!

I couldn't do either here is why.
1. I have a back drop and the un-cropped image would look horrible and unprofessional
2. I have 400 kids and to crop and export each size differently would would be a confusing nightmare for everyone not to mention the time involved as I have pretty 8 difference sizes in each package.
It should be able to be done like life touch offers these kinds of packages all the time

Battery Life Worse Now After iOS 6.1 Update on iPhone 5

Bought & using a new iPhone 5 since late December. Updated last night on the phone itself to 6.1 iOS. Now I am finding that the battery is draining considerably faster than before. I have seen the battery meter actually go down 1% at a time from when I unlock the screen to even swipe a couple of pages of apps and send one or two texts.
I did the expected battery-saving techniques of lowering the brightness, turning off the LTE and iCloud and Location Services. Manually push data for email was set always for me. But still battery dropping like a hot potato.
Any tips and/or ideas? I read on another thread about resetting the phone. Would that work? Needless to say I am aggravated and disappointed as this is my first new and current smartphone in over 5 years. And now this is all happening. Ugh!

The problem is more than likely being cause by corruption that occured during the iOS install or in the backup that was used to restore the phone after the update.
Standard troubleshooting is:
Re-boot the phone
Restore the phone from your backup
Restore the phone as a new device.
One of the 3 should fix the problem.

IPhone 6 battery life draining since 8.1 update

Is anyone else having problems with their iPhone 6 battery life diminishing since the latest 8.1 update? I notice I'm getting much less usage time per hour. For example, before 8.1, it would take about 3 hours of usage time to get to 70%. Now it only takes 2 and it gets worse after that. Here is a screenshot I took of the battery usage before the 8.1 update:
This is pretty normal usage timings for me (it was taken Monday, October 20th). Now, here is a screenshot from today, after starting out with 100% this morning:
As you can see, it's quite a huge difference. The weird thing is that messaging seems to take up more battery life than it used to. Yes, I do text quite a bit during the day but the frequency of this has not changed between now and October 20th. It shouldn't be using THAT much battery life. I took it to the Genius Bar yesterday to ask them about this problem and the girl told me that she saw some crashing from the Messages app in Diagnostics Information and she felt that maybe since the update, there was something causing that app to use more battery. So she suggested erasing the phone and restoring from an iCloud backup. I did this yesterday when I got home but, as you can see, the problem is no better (though there are no more crashes listed in the diagnostics information).
I have no idea what else I can do to fix this and I'm getting really tired of having to charge this twice a day now (I used to have to do this with my iPhone 5, as well). If anyone has had a similar problem, I would appreciate suggestions. And before you ask, I'm doing all of the normal battery saving tricks, like turning off background app refresh, not having it check for mail all the time (it's manual), brightness is down, I turn wifi off when not using it, I don't leave apps open, etc etc etc.
Any help would be appreciated. Thanks in advance!!!
Pooja

I turn off background refresh, mail push/fetch, and I turn off wifi and bluetooth if I'm not using them. I also minimize which apps use location services. Even when doing all of that though, the battery life became terrible on 8.1. Since updating to 8.1.1 all issues seem to have been fixed so I'm very grateful for that. I recommend anyone on 8.1 who is having issues to upgrade to 8.1.1 immediately.

My phone doesn't last more than two hours before the battery is dead. Any one know how to make the battery last longer? College student in need of help!

I used to be able to go all day without charging my phone but now I have to charge it like every two hours and as a college student who also works. I go most of my day with a dead phone. Does anyone know how to make your battery last longer?
