Bunch of advanced Noob questions - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

I used to have WM phones before (x220, SE X1), so let's say I know the basics. After a year of struggle with Android (Desire, SE X10), I'm back to where I feel at home; WM. But this time with a brand new HD2 (German T-mobile had them on stock at a very nice price). I already flashed a custom rom (Basic Energy 29.... C2.0) without any problems. I like the speed and the looks, but I am disappointed with battery life. So now I'm at trying tweaks. And here I feel a bit stuck. Apparently I forgot things.
So here are the questions;
What is the expected average battery life on HD2 on idle with all wireless connections, except GSM, turned off, and with all auto update things turned off also? (it is understandable that there is no fix value here. I'd like to hear few thoughts and experiences on this)
Is there a custom ROM that is generally known as a battery saver?
Is there some kind of a (virtual) map to show which radio is best for which region? (Croatia for instance)
Is there a specific radio which is gentle on the battery?
Is there an application to show what is (Cell, Display, Wi-Fi, CPU...) draining the battery in % like "Battery Use" on Android?
Is there an application like CPU Spy on Android?
In the tweaks, somebody mentioned the term "find battery saving wallpaper". What is this? I couldn't find it anywhere on the forum.
Is there a CPU managment application to manage (downclock) the CPU manualyl or automatically?
Is there an application similar to the Gesture search in Android (the only besides the implemented Battery Use and CPU Spy, that I miss form the Android)?
Is there a custom camera with less artificial noise reduction (I find it to be way too excessive)?
Is there a way to fit excellent X1 in ear earphones properly on the HD2. THe stoch HD2 heaphones are awful like on Desire too, and I still have those X1 earphones. The porblem is, the sound is skewed if I don't hold the answer button constantly pressed on the earphone's handsfree, so I used some tape and fixed it. However this way, I cannot use the handsfree. Can this somehow be adjusted?
Why do some part of the UI and some parts of apps look like they are scaled up to WVGA? This wasn't so on SE X1.
These are only the questions from the 36hours of use, so there could be more.
I did try to search and read about it before asking, but I couldn't find answers so fast, as the HD2 threads are really massive.
Thank you!

1... a day, day N a half.
2 ...not to my knowledge
3 ... no, what works for one wont necessarily work for the next.
4... not really, the latest supposedly has better power management, but I've not seen any evidence of that, PLUS the reception / stability is shocking on that radio, at least for me. Ask ten people you will get 8 different answers.

Buy TG01 or not

Have the opportunity to share my htc touch pro 2 with a toshiba tg01.
I have heard the battery performance is poor, and is the most important thing is a long music playback..
So, how long can the toshiba?
2 days if very light use, 1 day or less if your making a lot of calls and using wireless etc, there are 3rd party batteries by Mugen that can extend battery life massively
Should you buy a TG01? As a owner of a Tg01, and having just paid to get it unlocked, i think you are better off looking elsewhere, this is because Toshiba offer terrible customer support, zero useful software updates for their products, zero fixes for known issues, terrible battery life, and the fact there are better, albeit more expensive options, like say, the HTC HD2
As a TP2 and TG01 owner I tend to agree.
The TG01 has a beautiful screen and is super-fast, but it has too many flaws to recommend. Poor battery life and terrible in-call quality being the main ones.

for battery life , i expected much worse tbh ... my tg01 holds out only about 10-20% less than my xperia x1* i had despite the double screen and cpu witch really gets stuff done faster so u can put da fone to rest earlier
(*x1 has 1500mah battery , also got a 1800mah cuz it wasnt enuff)
but would i recommend it generally , no i wouldnt , and i wouldnt recommend any winmo phones to anyone unless they already had one in the past and know what kind of bug fest theyre looking into

Well said
Agree no more Toshiba..
Try anything else without TG01: you have Iphone, Htc and a lot of support for them.
But let us not forget the price peoples!
It seems that I'm the only person that would recommend buying the TG01.
In my opinion, you get a good phone for the money you pay (should be around 200 till 250 Euro max.).
You get a phone with a big screen and a good touchscreen (yes I think it's sensitive enough). You get Wi-Fi and GPS.
What more do you want to a price that is that low at the moment?
And if cedesmith suceeds with the project TG01 going to WM6.5.3 then the TG01 will even have less bugs.
In my opinion it's worth a try.
Maybe the battery is a little bit to weak, but for me that's not a problem. The battery remains two days for me...again...enough for me
I only hope, that our TG01 community gets bigger. The phone is worth it.
If you get a good offer, you should buy it I think.
Best regards,
DunkDream

Personally, I would highly recommend the TG01 for the use you appear to be wanting. It has excellent audio performance and with a Mugen 1.1 AH battery will happily last a full day commuting including maybe 3-4 hours use as a music player.
There is a discussion on MoDaCo about the audio side of things here which may be of interest.

After 9 months with it, this device exceeds my expectations. I'm a smartphone user since 2005, (My first one was a primitive Palm Treo 270 and some Windows devices after it) and this is the best device never tested. But you must understand that a Windows device is not easy to manage.(and they never will be if Mr. Gates boys doesn't change it....)
It's true that the TG01 hasstill some unsolved problems, as most of new devices in their first age. It's also true that Toshiba is absolutelly useless in giving support to the TG01
Pros:
-Thickness
-Great screen
-Best device for the money that you pay
-The best Video player never seen . You can play mostly everything on it and with the best benchmark values in the market.
-Great Sound Quality. With SRS Wow it's a dream.
-Host USB!!!!!! You can use USB keyboards, game pads, mouse, bar code, hdu, pen drive, .... Remind: HTC can't do it!!
Cons:
(Design)
-Too small battery
-No separated headphones connector
-You can't charge it and connect USB at the same time
-Stupid SD position. You must disconnect the battery to change it
-No TV Out
(Software)
-Call quality (sometimes)
-Sometimes freezes a bit (as other WM devices)
-Stupid Toshiba's limitations when talking, when battery it's under 20%...
-Still no software for movement sensor
I think that if you have a good opportunity, you must take advantage of it. And if at the end you don't like it, you can always sell it on Ebay for instance.
I wonder if these lines will be useful for you . Tell us about your last decision!
Cheers
wait for tgo2 ot ko1
Hey thanx.. I get the message that the xperia x10 is aviable in 2 weeks..
TG01 or TP2
Talking from Experience, TP2 is the better phone, my cousin owns the TP2 which I have played around with a lot and I own a TG01.
TP2 is an all in one complete solution.
TG01 is very nice, but HTC Touch Sense Pro is just too good. And unless you know much about Manila, I wouldn't look at a TG01.

[Q] Battery questions tips advice etc

So i love the evo 3d its great, but.. i dont even use it much and the battery is dead half way through the day. I bought a extra 2 battery and a external charger and just charge the other battery while use one and then switch when it gets to 5%. The replacement battery actually runs cooler than original. (according to battery monitor app) replacement runs at around 80F and original 90-100F
Im really a android newb and dont even know how to calibrate the touch screen (maybe there isnt evne a place to do it) im used to windows phones. Is there some tweaks to get more use out of the battery? also the battery says 93% when it finishes charging on the external. I guess it gets to 100 then starts to drain?
Sorry for my english and ranting. Thanks in advance
Have you rooted your phone? If not, you could try juice defender. It manages different things about your phone like data and what not. If you root it, then I suggest getting netarchys kernel. I'm using empiires beta ROM with netatchys kernel and my battery has lasted 20hrs (I haven't used it too much though. Just for XDA and text messaging)
Sent from my PG86100 using XDA App
have not had the need to root yet damn im lazy ill prob do tomarro. but was thinking about mighty mike rom. is empiires beta roma bad ass? i do alot of txting light calls and few games and it seems to die fast. maybe if i root and underclock it? i really dont need 2.4ghz of cpu power on a cellphone 99% the time. i can see if i was skyping and watching hd video but ive yet to do either those things.
Yep that's exactly how I use my phone for the most part. Its pretty good for a beta. Its suppose to be as AOSP as possible and sense is almost completely removed. Only problems I've had is that you can't change the ringtone or print from the default printer. And you can't view 3d pics because he has the AOSP gallery instead of the HTC one. And you can't get to the gallery from the camera app. I'm not a big picture taker though
Sent from my PG86100 using XDA App
Also check and see how many different things you have running in Sprint Zone, more than likely you will have everything turned on in settings. You need one up though, so I normally leave help on.
Head over to the thread linked in my signature and toss me a thanks/comment in the thread if this helps, please.
This thread is recycled from my Evo 4G days, hoping to share some of the love with newer users. Over the time I've been on android, I've learned a few simple things that can greatly assist in the battery life of our wonderful smartphones.
If you read the thread and like the tips, have a new one to suggest, or have a revision, please post it. This will ensure that the thread remains visible for those who need it, as I'm sure the moderators will not sticky it.

General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users (everyone, for now):
1. Turn off all radios when not in use.
(gps, Bluetooth, wifi, data, 4g) Use a widget like the default HTC power widget or Switchpro from the market. The 3D's updated Sense 3.0 allows users to access these radios and other settings from the notification pulldown menu, , under the "Quick Settings" tab. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you
This will prevent your phone from staying on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.
Menu>Settings>Display>Screen Timeout
I use 30 seconds.
6. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
7. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to Menu>Settings>About Phone>Battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.
-This is done by hitting menu>settings>monitoring enabled. Then after some time has passed, ht menu>monitoring>history>change tab to top apps, and see if anything is above, say, 2-4%.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
Root Tips LIVE
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 3D Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 0-2 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 2-5 of screen on
* *Heavy usage – LOTS of video watching and games, 3D pics or video, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans. 5+ hours
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

Any views on this Amazon review?

I'm thinking of buying a GS2 and was curious when I read the review below on Amazon. In particular, the comments in points 1 and 3 regarding CPU/battery usage are a little worrying. Does anyone here agree/disagree with this?
**** 8 WEEK UPDATE ****
Having had this phone for two months now I thought I'd update this. There are several things now about Android and the GS2 in general that are now apparent to me and may be deal-breakers for some of you, though it should be noted that most of these are applicable to all Android phones, and not just the GS2:
1. If you use your phone as your primary music player (e.g. like an iPod) then this is NOT the phone for you - it (as far as I can determine) has no dedicated hardware to decode audio and so it uses a lot of CPU power to play music. The phone will get very hot in your pocket from the CPU heat and within 4 hours the battery will be completely dead. This turned out to be a deal breaker for me as I use my phone extensively for music playback, and the iPhone is still the only phone I know of that gives 40 hours playback.
2. Gapless audio playback is not supported by Android, though some players buffer the next track to simulate the feature (e.g. PowerAmp) if you're willing to pay for them. Gapless playback may be supported in future Android versions, though I don't know how or when one could find out exactly what version of Android will support it.
3. There is a very common bug in the GS2 whereby an application called 'Wifi Sharing' will randomly start itself in the background and consume a huge amount of CPU power (doing nothing) and drain your battery SEVERELY. Your battery will be dead in 6 hours if you don't 'force close' the application. The only solution at the moment if you have this problem is to install something like WatchDog Lite and set up an 'alert' to warn you when Wifi Sharing starts to overtake your CPU so that you can 'force close' it.
4. For all of Android's beauty and the Touchwiz inteface Samsung has put on top of it, I've become aware of some quirks of Android, especially relating to the (VERY) inconsistent use of the menu button. Many applications use this button differently (or not at all), showing different menu items on this button depending on what screen/section you are in on the application. It's definitely not intuitive in this regard compared to iOS, though some applications do use it appropriately and in a logical manner. On the other hand, the 'back' button is fantastic and I think Apple should employ one in their phones, too.
5. Screen burn-in. I've not seen many posts about this around the intertubes, but there is what can only be described as burn-in visible on the notification/status bar of the phone when you are using an application that hides the bar (e.g. having a white section where the status bar would otherwise be displayed). It looks exactly the same as burn-in looks on a plasma television; a slightly dark/grey area where the reception indicator, clock, and other indicators normally display. I suspect this is related to the super AMOLED plus screen technology though most people will probably never notice it - if they did it would be discussed in forums all over the internet.
6. Complications with applications are frequent. Unfortunately it would seem the Android market is severely fragmented due to the shear variety of different Android hardware (i.e. handsets) available. Almost every app you download will have comments attached saying things like 'won't work on HTC Desire... ' or 'If you get the so-and-so issue then uninstall, reset and reinstall' etc., etc., Coming from iOS, this is rather jarring and definitely does not fly on a 500GBP product. Furthermore, with the exception of the very common/popular applications, you are very likely to encounter flakey apps that consume too much battery power or randomly crash/force close (or 'FC' as it's commonly called in the Android community)
7. Speaking of battery power... In my initial review (below) I mentioned how awesome it is to have widgets on the home screen. This remains true, but generally at the expense of battery life. This, combined with the battery drain experienced when using the phone for audio playback will very quickly drain your battery. You will be lucky to last the working day if you also use the phone on the road to receive and respond to emails in addition to your music, surfing, widgets, etc. This may be considered an acceptable trade-off, but no one warns you of it beforehand (at least I wasn't aware of it, and just assumed I'd still get at least a full day out of the battery). I've since learned Android phones have a horrible reputation for poor battery life. Expect to last around 12 hours with medium-light use.
With all the above said, this remains an outstanding phone and by all accounts one of the very best phones available on the market. It is super-fast - faster than my laptop - and the physical design is beautiful. For any existing Android user this phone is a dream. For people coming from iOS, I hope the above update has warned you of some of the limitations on this otherwise outstanding product.

Is the comment regarding audio playback accurate? (i.e. the lack of dedicated hardware results in excessive CPU usage and battery drain)?
Sounds like an apple employee got bored...
The SGS2 is great for music playback. I use mine every day in work, for 8 hours and only ever get down to about 50%, and that's with some web browsing thrown in and texting.
Also, i thought it decoded most if not all audio formats fine? I have mp3, wav and flac files in my playlists and no problems there at all.
On my one hour daily commute..i listen to music plus screen on time at like 60% full brightness when i switch between songs whilst browsing between my news and football apps..and i probably use about 10-15%.
Wifi sharing annoys me..but i didnt notice extra large battery drops.. when i first got my phone i had wifi on all the time and it was fine. Since then i rooted my phone and 'froze' wifi sharing...so when my wifi is on...i don;t have to worry about it.
The super amoled screen gives this phone an edge on battery life above other android phones even though it still isn't as good as i hoped. And the standby time is really good.
Remember iphone battery is not removable so once you ruin it with the inevitable half charges and overnight charges your in the sh*t. You can atleast buy a spare battery for androids and keep it in your back pocket. lol jus read what i wrote...this phone has turned me into a bit of a fan boy

i dont understand this the sgs2 has a dedicated yamaha audio chip it isnt running as good as the wolfson from the sgs1 but it is still pretty decent in terms of audio quality
as for cpu useage and excessive drain on the battery i use music all day at work and its fine , it doesnt get hot , it doesnt drain battery badly , it doesnt run cpu at maximum
i use my sgs2 as my main audio device as i have bluetooth stereos in the car and home and some ok headhones from work and i dont have his troubles at all

The sound card is different from the SGS1, which was considered more efficient. This is why a few sound amplifier apps refuse to work with the SGS2 (Voodoo Sound) etc.
Obviously Samsung decided to cheap out on that aspect.
I have not seen any color burn ins, or anything like that.
You have to remember that people who dont like a product are more likely to write a review .Saying that i use Amazon reviews to get an idea about a product or alternatives a lot before buying .

[Q] Want to get a Mini Pro, but --- battery life?

Hi everyone,
Longtime QWERTYphone user here. BB8830 > BB 9650 > Motorola XPRT. The XPRT has a fantastic battery life, and the keyboard is passable (but inferior to the BB9650, in my opinion). I've been reading reviews of the Mini Pro and think I'd like to give it a try. There are a number of advantages and disadvantages, but the primary thing holding me back is the issue of the battery life.
I searched this forum for every post mentioning "battery", but I still don't have a clear idea for how long this phone will last me. Many of the reviews say things like "I can get through a whole day with light use" but that doesn't really help me. Can anyone give me a more or less objective measure? (e.g., "I can get 5 hours looping an AVI file at 1/2 brightness")
I'm primarily interested in hearing about the battery life of a non-modded, non-rooted, stock phone. But if you can give me a before-and-after, that would be great too.
Thank you!
Hi
I have XMP. The stock battery is not so powerful (1160 mAh), but the screen is small and this is a plus for battery life.
I've no objective tests for you, and perhaps they're not so useful, 'cause battery life primary depends by user's utilization mode.
Always valid the 1000-times listened recommendation for saving battery.
With root you can set a cpu manager and save something; with only 2G, data on and screen off (with low cpu values set) I can make a day with almost half battery.

Awful battery life?

Hi all,
Got my 920 a few days ago, and while it's a beautiful phone, I'm finding the battery life to be awful.
I've only installed a few apps on it, otherwise it's vanilla. With WiFi and GPS off and only moderate Internet usage (mostly Facebook and IM+) i get a max of 10 hours out of it.
My Galaxy Note easily does twice that with the same usage.
Is there anything I need to check/look for, are there apps that show what's chewing through my battery so much?
I love the phone but that sort of battery life means it can never replace my Note as my main phone.
Thanks!
I should add, it's running the Portico update. No crashes or random reboots that I've seen.
I have only had mine for a few days, but I have found with all WP8 devices (and I have tried most) a hard reset made a difference to battery life. Annoying, but true it seems, well, true for me. I have no idea if it is a placebo but might be worth trying if you can be bothered.
For your info, I am getting good battery life on my 920.
You need to discharge and recharge the battery a few times before the battery life gets better. In about a week you should find the battery life improves.
It was the same for WP7 too..... The software will calibrate the battery over time.

I actually did a hard reset when I first got the phone home, out of habit really. I don't mind doing it again, but maybe I'll give the battery a few more days and see what happens.
Also check your background apps.
it'll get better
when I first got my lumia 920 the battery life was shorter than my old NL 900.. but after a week or so and after I did a deep cycle now the battery will easily last for 48 hours... in battery settings it usually shows 4-5 days :good:
battery life is hit or miss, some days you'll get wonderful battery life and others its horrible, I know that its hard to measure battery life because you just cant replicate the exact same usage everyday. I find it hard to believe that the galaxy s3 (basically the same hardware) has better battery life, battery is only 100 maH more.
I honestly believe its a operating system/ application issue, I believe that there are some applications that are cycling and wasting precious juice from the battery. better coded apps/ better OS control will really be a big deal in the next os upgrade.

I've found turning off background tasks which are not required makes a big difference on the battery. Each time I install a new app, I look at the background tasks and see that it doesn't get added. Only tasks I have running are weather and a news reader app.
Also, I will not allow location on apps that don't need to. Searching for location when an app opens also drains a battery somewhat.
That being said, with my use, I easily get 2+ days (48+ hrs) of battery life.
May be it have to be synced
In my opinion, one reason why this phone need the run in for the battery life is in the first few days it need to be synced with many clouds, facebook, facebook photo, nokia drive....etc. As this will make poor the battery life in the first run in. But after one week everything done, the battery life becomes better. Just guess.
I've also noticed that with bluetooth turned off I get substantial more life out of the battery(but I tend to forget to turn it on when getting in my car, then I dont get calls on my cars bluetooth). I agree with disabling push and do a manual poll on your email servers, I dont have facebook or any of that stuff on the phone. Im mainly on twitter and on my email.
from time to time I see the Location services running when I unlock the phone, I've disabled the location service on bing search but that still comes up from time to time. Like I mentioned before I think the OS has tons of pros and like any other OS in its "early stages"(I say this because windows mobile has been out for some time pre iOS and Android, but it will get better over time as the company realizes main stream OS are getting replaced as the go to home PC.
My experience with Nokia Phones is they need 1 or 2 weeks to get the full battery life....
The first 4-5 days they really have a horrible battery live.. But as I said it's getting better after 1-2 weeks...
BTW I'm really impressed with the battery life of my HTC 8S, I'm getting 2-3 days out of it with heavy usage...
My Lumia 920 achieves a little bit more than 1 day..
I've had the phone since it was released(when it really bad battery problems), I was going to go with the 8x but I really love the camera on the lumia 920.....
Ok for the past two days I've been using my phone with bluetooth off and i've been getting really good battery life, a friend of mine has a surface rt and he was having an issue with the battery depleting even when he left the device on sleep for hrs, he noticed that after disabling bluetooth the issue with the battery went away, this clearly points out an issue with the os and the handling of Bluetooth.
Surface RT and Lumia 920 have a totally different OS i don't think you can compare them that easy...
And it well known the Bluetooth deceases the battery life of every smartphone... It's the same with NFC (Tap&Send) and super sensitive touch or Wifi...
Just turn off the things you don't need...
My Samsung Note 10.1 tablet has no noticeable difference with Bluetooth on or off (that is, not actually using it, just having it enabled). It's using BT 4.0 which has very good power efficiency.
Any idea what revision of BT our Lumias have?
It also makes a difference if you switch your bluetooth on to be visible or not...
Ii is the same with Wifi you can activate to be notified when open networks are around... If you do so.. your wifi will use more power because it is constantly searching for new hotspots...
Well, it's been a few days & recharges, and it seems the battery is getting better.
Thanks for all the suggestions from everyone. I was severely disappointed with the initial battery life, and while it's getting better, I hope it keeps improving. Switching background data services such as push mail and chat makes sense when it comes to preserving battery of course, but so far from all the smartphones I've owned, this is the worst performing of all in terms of battery. I don't want to have to manually check mail or log in/out of chat, since that defeats the purpose of having a smartphone imho.
It's the only thing I have against the Lumia so far... even though WP8 is not as customisable as my Android phone, I certainly appreciate the design and how it works. I'll just keep crossing fingers for more battery conditioning
I think there is something like a help app from nokia on the phone...
You can disable the live tiles you don't use and the automatic xbox live sync service...
I wouldn't totally disable email sync... I just reduce the syncing interval...
If you have a lot of email accounts (maybe more) it even makes sense forwarding them all to a new email account and syncing all your emails
with this 1 account...
There are a lot of dirty little tricks to improve your battery life... Maybe every
single one don't make much difference... But all of them do...
With a lot of frustration, I have been experiencing high battery drain also, with the phone staying warm even while idle.
Following various comments, fixes, could be' on various forums, I hard reset my new, less than one week old, phone.
I was kind of annoyed, surprised it took a very long time to recover, with a picture of gears churning on the screen.
Finally it booted up with a message, reset or restore. Wasn't expecting the choice. I chose restore to see what's up.
There was an amazing amount of stuff to restore.
After restore completed, my phone was still having battery drain issues. I decided to check out what this back up and restore thing was.
Pardon me I never read the manual. No need to go into discussion of the process.
I then chose to disable back up and restore, soft reset, and boom. Battery usage is now at -2%/hr. instead of -12-20% idle.
Have any of you tried this?
