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.
I have the AT&T Samsung Galaxy S II phone, and it is absolutely brilliant. Speeds are excellent - no lag. Screen is absolutely AMAZING. Camera is the best I've ever touched.
BUT, the thing that bugs me is the battery life. One of the selling points of the Galaxy S II to me was the "Amazing Battery Life" which has been praised. I have only owned this phone for two days (charged only one and a half times), but I have not seen this "excellent" battery life AT ALL.
Any tips or suggestions? I have read that the battery in this device "improves" after some time (a few charge cycles). Is this true?
Thank you
hey congratulations on your new samsung. I got mine when it first came out and had the same problems with batteries. My best suggestion is to familiarize yourself with custom roms and learn everything you need to know about flashing and rooting, and when you're ready look into installing a custom rom. Cognition v1.5.1 is a really good choice because of the fact that it removes a lot of the bloatware that automatically runs when you turn the phone on (which drains the battery quite a bit). Also some other ways of dealing with the battery life is to reduce the brightness as much as you can handle (the highest setting of brightness on any phone is never a good idea for battery life).
if you search around these forums you will probably find better help from people who know more about this stuff than me. However, as someone who went from never touching android in my life to learning it all with this phone I can say your best bet is to learn how to flash and mess around with the firmware. That coupled with basic battery tips will help a lot.
also one final thought. If you download battery calibrator from the market, charge your phone to 100% then take the plug out and run it, let it drain down to 0% then start the charge over that is the quickest way to fix the battery issues. (this would only need to be done once, or every time you flash a new firmware if you choose to pursue that).
hope I helped!
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?

Good morning good evening and good night everyone,
As the title says, I'm looking for any recent kernels for an s9+ with solid battery life improvement, with the current stock android 10 ROM I get 4 to 5 hours of SOT with medium work load.
I've looked into the kernels and roms available on the boards but I need a solid recommendation, preferably from experience.
Thanks in advance

People should change their behavior not kernels I mean i do agree that any custom kernel, rom always gives better battery life, BUT end user is the cause of bad battery life, i often notice people have turned on EVERYTHING they can, NFC, Bluetooth, Wifi, Data... why???? if you have wifi-turn off data, if you ave data turn off wifi. If you don't have anything connected to Bluetooht-turn it off. Lower your screen brightness, many people use SUCH A HIGH brightness it burns their retinas. With Every phone i had last 5 years i need to charge battery every 3rd, sometimes 4th day. But i dont live in phone. I do have computer, phone is phone not replacement for computer. My words may sound like nonsense for nolifers who lives in phones (facebook, instagram and so on), but that's truth.
So to answer your question - ANY custom rom with custom kernel will be better then stock. Also make sure your resolution is fullHD not maximum, that helps too, and try lowering brightness even tiny bit. screen is biggest power consumption (if not gaming, but people use consoles for gaming)

I totally expect to drain my battery when I'm on a workload, but there's a discrepancy with my work load and battery usage, sometimes the phone sits idle and it eats 10 to 15% in an hour (no always on display or anything else). I've never been a guy of irresponsible phone usage either, I like to keep track of what my phone is doing and I usually turn off all the extras i'm not using (it's second nature to me to do so just like how you would check if your keys are there every once in a while). I'm not looking for a miracle kernel that saves battery even when i'm using my phone irresponsibly. I'm just looking for a well rounded efficient experience with my phone which doesn't get me through the day.
Thanks a lot for your answer and do you have any specific custom rom names or kernels that you've tested and would suggest, please?
Hi everyone, I have had a Poco F1 for the last three years, and I'm not planning on change it for another phone anytime soon, but the thing is, that I'm trying to get into genshin impact, but due to work, I don't have much time to play it at home, so I would like to play on my phone on breaks or on the bus, but there's two problems,
The first is performance, the game really chugs a lot even on low settings precisely when I move the camera, and I've seen a lot of people on the internet that can play with better settings with better performance.
The second is the battery, after a battery replacement the phone is not that bad on normal use, but when gaming, it drains a lot of battery, I think I can't even get two hours without charging it while playing, and I would like to get the same kind of battery life I was getting on when i first got the phone. (I remember playing PUBG, when I first got it, for hours without charging it)
After the long introduction, I would like to get some kind of advice on what custom rom should I flash on my phone regarding this:
-It has to have better overall performance, since the gaming performance is so lackluster and poor.
-It has to have better battery life (yes, I know that balancing the two is kind of difficult, and I've seen a lot of performance specific roms and kernels but I really don't know about the battery life on those), and keep in mind that this is my only phone so I would like to have a phone that can last me one day, on normal use of course.
-It has to support some of the features that the stock rom has, like face and fingerprint unlock, and notch support.
-And lastly it would be essential that the rom supports safenet (since I'd be using banking apps), and google applications baked in. (I would as well not like to root the device).
When researching, I always come to these two, the Pixel Experience and the Corvus OS, but I know there's a ton more out there.
So I would be happy if someone gave me some kind of advice on this topic.
Thanks.
Edit: I´ve never done any flashing of custom roms on any phone so i dont have experience.

You can find everything you need in my POCO F1 Ultimate Collection & Guides. (Scroll down for guides)
About ROMs, I recommend you to pick one the awarded ROMs. Keep in mind none of A12 ROMs have Face Unlock (yet). If you really need Face Unlock choose A11 ROM but A12 is much smoother and better overall and support is active.
Carrying around a powerbank isn't possible? Gaming drains a lot of battery... Could be that Genshin Impact is more taxing on the battery that PUBG. I remember 25% active drain in the latter.
Regarding battery life crDroid is fantastic but the stock Optimus Drunk kernel in A11 wasn't geared towards hardcore gaming. OD kernel is no longer being updated for F1 and in A12 the default is the generic? "perf" kernel. You could try a few of the custom kernels available for A12.
Yeah, I could carry a power bank, but the most pressing issue is the lackluster performance.
When I referred PUBG, I wasn't comparing it with genshin impact, I was comparing the battery life I had in the beginning playing that specific game and the battery life I have now in the same situation.
I have been looking into arrowOS, in Android 11, it seems to have a decent performance increase in relation with stock with better RAM management and good battery life.
I also saw a bunch of comparisons between MIUI 11 and MIUI 12, and the battery life on the first "reminds" me of the kind of battery life I was getting when I got the phone.

Did you replace with the official battery? Majority of the third-party batteries are rubbish. Even in case of the official battery it's possible to lose out on 10% of the rated capacity due to the aging process, 2-4%/year. It's difficult to get the same battery life in changing workloads like games anyway.
