All,
I am experiencing serious battery drain on my TyTn. WiFi and Bluetooth are disabled and 100% charged battery drains overnight. This can't be normal even with 3G. Does anyone else experience this?
For me this is normal for 3G. My TyTN will last roughly 24 hours with UMTS/3G turned on, and 3-4 days with 3G turned off...
Not even lasting that long
Mine isn't lasting that long... How do u turn 3g off?
Phone -> Menu -> Options -> Band (?) -> Set it from auto to "GSM".
Use bandswitch. It will do the change very fast.

I think the Battery Drain problem relates to always on 3G connection. Infact I had also configured Outlook Software to check and download the emails from my POP3 Server after every 15 minutes. Apart from that, I was not using the Internet connectivity for any other application. But still around 10 to 15 percent of the Battery was getting consumed every Hour and which was quite high.
I have now Hard Reset my PDA and configured the PDA to only use GPRS (i.e. GSM) for checking the emails after every 15 minutes. I have not installed any additional Software after Hard Reset and now I am using the PDA as per the default factory settings. Only Outlook is checking the emails after every 15 minutes.
Now the Battery consumption has been around 30% in the last 12 Hours (i.e. from 100% to 70%). During this period, I have not received any calls and I have not used my PDA for any other purpose.
Kindly advise if the above consumption is normal or is it still on the higher side.
Many Thanks.
this looks normal to me. i do about 20-30% for a day depending on the amount of mail I get. this is through GPRS of course. 3G seems to suck battery at least 100% faster
It also depends on the Radio you have installed. I had 1.18 and experienced a heavy drain on 3G along with other users who upgraded to the RSA 1.35 ROM release. Since moving on to the 1.27 radio my battery consumption is now acceptable again.
Maybe this assists.
HTC Touch Diamond2 is next on our roll call of MWC debuts but this time it's less about the brand spanking novelty and more about balanced and sensible upgrades. People tend to have second thoughts about sequels but this one here is signed by HTC and may as well be the director's cut of a blockbuster.
I have a battery drainage problem too. I wish I can say mine drains within 12 hours. Once fully charged @ 100%, removed the charger, it drops 1% or so every 10-20 secs until ~80%. There onwards, if I use the phone, it drops drastically 5-10% each time I talk depending on the length of the conversation (most conversation barely reach 5 minutes.) If not used, it will drain the remainder within 6-8 hours. I tried changing a new batter and flashing with different ROMs and radios from this site but it doesn't seem to be helping. Any help would be greatly appreciated.
I also expirienced battery drainage at my Hermes. What i do is i turn off my 3g and set my email send recieve to 30 minutes..
I noticed that when i have my data connection always on, it has a high persentage of battery drain..
The reason I am asking is I am trying to track down a battery drain issue. The only thing I think can be causing it is the fact that I have my phone set to check 4 different email accounts every 5 mins.
I have a 3000mAh battery and I am able to kill it in 8hrs. I seem to remember someone talking about an app that could tell what apps or services were causing the most battery drain?
I am thinking about doing a test where I turn off automatic email checking and seeing if the battery lasts any longer. I use the phone for business as well as private use so I need to keep track of things when someone needs to get a hold of me. So I use email a great deal.
Ya.. that seems pretty fast.
I would also recommend checking the radio version that you have. Some people say that some radio versions kill the battery faster than others.
Check that out.
I have push mail set for one account (MS DirectPush with an Exchange server) with a 4/5 minute update interval, and I get acceptable battery life... It's not fantastic, but what do you expect for a PDA smartphone As soon as I fire up pRSSreader to check four RSS feeds (even if I set the interval to 3 hours!) my battery life REALLY suffers, and I'm in a 3G area - close to a mast, stationery - all day every day. The Palringo client REALLY kills the battery, we're talking about 3/4 hours to get to 10%.
SPB GPRS Monitor is useful for seeing if there's any data throughput going on, and the BatteryStatus Today plugin is also useful for seeing current battery drain in either mW or mA, so you can kinda figure out what's going on with your phone at the time (that and acbTaskManager to see if there's any processes maxing the device's CPU out, which has caused me battery drain in the past). I've got a HERM with v1.05.05.00 radio, for the record.
I've been having the same issue with my Vario II...
The battery life was relatively good when I didn't have my web'n'walk connection enabled. But now I have DirectPush enabled to check emails on an Exchange server set for 'as items arrive' aswell as another three POP email accounts.
The GPRS is almost always on and on full charge will only last me about 8-9 hours from 100% charge. If I'm out for a continous stretch for more than that time- I'm in trouble (as I was yesterday!)
I'm guessing this is normal behaviour then? Not too good if it is (!)
Well I went from 4 accounts every 5min down to 1 account every 5min and my battery life doubled. So yep constant email checking does kill the battery. Oh well, I have my important account set to check every 5min (may change it to 20mins) and my other accounts set to once a day, which I usually just check manually when I have a few min.
There seems to be many other threads on this issue and some say, even with multiple accounts setup, battery life is in the region of 20hrs. Changing to a different [radio] ROM seems like one of the solutions.
Sorry guys...I know I'm kinda late joining this discussion, but I thought I'd put in my two cents...
Checking your EMail in the fashion you described in your first post definitely drains your battery. I was in the same situation you're in: about 4 different accounts, set to update around 30 minutes or so...my phone was beeping "low battery" before the afternoon was over (and that was after being charged the previous night!)
Not only that, but I'm convinced that the "always-on" state that the radio was in from all that EMail-checking is what caused the radio to "burn out." I had to get a new 8525 after that happened.
Good luck with your situation. I'm looking for a solution myself.
Guys
I dont know about all of you but I have spent the best part of a few days trying to be tolerant with the appalling battery life.
to set the scene: -
- it is a native orange build (upgrade from them) it has exchange activesync emaill and I have tried it with and without push activated (10 minute polling when not constant)
- It has one other e mail account - Hotmail, which is connected to sync every 2 hours
- it has NO other applications of any kind, it is not used for GPS, browsing etc (a deliberate ploy for me to see if the basics work) and the battery life is a complete joke, if anything it is worse than my previous WM devices. a full charge which is disconnected from the mains at 10am in the morning means I am down to a single bar by around 6-30pm. in this time I have checked mails on occasion, had about 30 min worth of calls and thats it basically
I, like many people on this forum am a seasoned user, but I would expect a minimum of 1 working days use (say 12 - 14 hours) and this is just not the case.
I will be returing this phone under my 14 day policy, but as one last try, I just wondered if anyone had something really obvious I was missing? all of the settings are 'out of the box' and i have used tweakHD but I must confess I do not want to have to mess about with the settings too much and quite frankly I dont see why I should, unless this type of performance is considered normal these days!
any thoughts guys?
regards
Kerry
12. Disable 'Beam' in Settings to conserve power.

I'd do the same too if I were you. A complete rundown of the battery on not so heavy usage in 8 hours is definitely not standard. Might be defective. Your battery should last you at least 14-16 hours on that type of usage. Oh and one other thing as an after thought, you mentioned the phone was new. Did you run the battery in a couple of cycles yet? A complete charge and a discharge of about 4-5 cycles sets the battery in its paces. Fyi.
I would take a look at these two threads.

thanks for the replies
thanks for the replies, I will study the replies and get an exchange unit based on the comments.
It has had three full charge / discharge cycles in the last 5 days, it wasnt difficult given how fast the battery ran out!
thanks so much for the help guys

Mine also didn't last for more than a few hours on the first week, cause of the excessive playing around with the new toy, but after that I get 2 solid days on average usage with 2 bars to spare before I put it back on the charger.
When I have Windows Live Push ("as items arrive," "always") enabled on my HD2 my battery life tanks. In about 8 hours it drops 20% or more while in standby without doing anything else. That's about 40 hours of standby battery life.
When I have it set to manual my battery drops 2% in 8 hours. That's around 400 hours of standby battery, which makes a lot more sense.
Is this normal? Does anyone else experience this using this feature? I am seriously curious as to why MS Live push e-mail keeps up an ACTIVE data connection that is not defeatable, and why it insists on wrecking battery life. If this is a consistent phenomenon, then push e-mail in this way is absolutely useless.
I have seen people with MS Exchange-based push (not Live) email get fine battery life, so this bothers me.

It's perfectly normal mate. For push to work your phone needs to keep an open connection to the live server, which means some kind of heartbeat or keepalive message being sent every now and then (anywhere between every 30 seconds to every 10 minutes - it varies from software to software). This is therefore constantly using your battery. I was amazed at how much my battery life increased by changing the live synch settings from "as items arrive" to "every 15 minutes".
Look at turning down how regularly you update things like the weather and facebook too, and you'll see just how good the battery life on this thing really is!

I know, but one of the reasons I got my HD2 was because I'm a MSN junkie. I have read that people have got "2 days" battery life with MS Exchange push and that makes me feel kind of bothered. My Motorola Milestone with Gmail push didn't see anywhere near this kind of battery drain.

i have MS Exchange push e-mail using 3G/HSDPA and I have experienced extra battery life when compared to POP3 email synchronization !
It seems to me that push e-mail is more energy efficient.
Last night @ 23h00: 100% battery. This morning 9h30: 95% battery...
Well my phone went from 1 day of average use to 2-3 days of average use, just by turning off push email, so we're getting different results from the same thing.
It has been almost a month since I've gotten the Galaxy S2.
I literally waited like a longing puppy for almost half a year to get this into my hands.
I have to admit, it is one of the most beautiful creations to ever grace our earth, but gosh, it has this one big, big flaw... (for me) battery life. Before you dismiss this as another battery life complaining thread, hear me out...
I have tried EVERYTHING.
Ever since 2.3.3, battery drain. Then 2.3.4 was announced... NO MORE BATTERY DRAIN. The news caused a burst of elation, but it was all too brief. Flashed to 2.3.4, same deal.
I've tried all the ROMs-- Litening, Villainrom, Cognition, Infusion (now defunct).
I've tried several kernels -- the standard CF kernel, neophyte's, mirage, etc.
I've calibrated my battery after each flash.
I've tried downclocking it with SetCPU.
I've frozen so much with TitaniumBackup.
Dormancy settings, system update settings, modem roms, I've tried them all.
I even purchased, in desperation, a third party battery which claimed to have 2000mAh capacity.
All to no avail. Nada, zilch, non. NOTHING has worked for me.
Last night for example, I had charged my phone to 100%. When I woke up 7 hours later, it had fallen to 63%.
Therefore can deduce that consumption is is about 5% per hour with screen OFF.
I have also made it a point to test a different ROM/kernel for at least 3 to 5 days before I make a change.
Now I really don't know where I'm going wrong, yeah I do have a few widgets and stuff, but what is a phone like this without widgets?
I am getting so sad over this issue. This phone is so perfect in every other way.
Why? Is it just me?
One no mention of actual battery life .
Two phones get fed up with multiple roms kernels etc rammed down their throat and dont work well .

What exactly do you mean by 'battery drain' ?
Starting an new battery drain thread without even describing the type of battery drain is not a god start for this thread.
What is your idle drain? (% per hour when not using the phone).
How much "display on time" do you have when the battery is starting to be empty (no guessing, hard number from the battery menu please). A lot of people underestimates how much active use they have with SGS2.
Please also add graph for battery statistics, both the first page and also for the battery graph (press the small graph on top).
Just trying different ROM's in order to solve a battery drain issue is a bad idea, it is much better to find the root cause of the battery drain and solve that specific issue.
I mean I leave it overnight, and it falls from 100% to 60%.
It has never lasted me beyond 9 hours with mid level usage.

Apologies, my post has been updated. I don't have a good graph with my now since I'm charging, but I will post one up tomorrow.
Do widgets really make a big difference? Because that's the only thing that I have not really tested.
Could very well be a misbehaving app or widget. My phone in idle uses 0.5%-1% an hour with wifi on. Without wifi it goes slightly faster strange enough. I have some widgets that update every hour, gmail push, whatsapp and Samsung account sync.
Test without syncing and widgets and then re-enable things one by one to find the problem.
Another battery thread. That really IS depressing.
i just got my phone few days ago, battery life isn't great so far but it isn't as bad as your case.
I would recommend you do proper tests after starting fresh. flash a stale official rom, keep the phone barebones, dont install apps etc.. then test bat life with phone call usage.
Then slowly start adding and enabling things like gps, auto sync, background data and so on, till you find the cause. I think the battery life thing in the settings can help too.

40% overnight is huge, I get approx 5% in 7-8 hours.
With 5% drain per hour with no usage, haven't you tested to turn off things until the drain stops? I would start with wifi, SGS2 doesn't work well with some routers. Then just continue with the usual suspects: widgets that connects to internet etc, email sync, facebook etc. (freeze with Titanium)
Do this systematically, you could turn off several things at once, but not too many, try to find the real cause.
There is of course a possibility that your phone is broken, but that isn't my first guess.
Why does no one try Juice defender???

Oh yes, that night the 40% drain was with Wifi on, and I heard that there have been issues with the DIR-655, which I am using.
Anyway, even with wifi off, my battery life fell from 100% to 83% with a very slimmed down ROM, everything that could be frozen, frozen.

I would, but the thing is, the battery life should not even be that bad in the first place.
Sounds to me like you have a rogue app. I get 12,14 hours of heavy usage with brightness set to roughly 75%.
Don't flame him. He has tried alot things prior to posting. This is the place to post. Try the criskelo rom. It is a great rom with great battery life. Freeze wifi sharing. Delete apps at the beginning that you don't use all the time then add extra apps one by one and see what impacts the battery level the most. Check update schedules for things like news widgets and beautiful weather-I have mine set to six hours or so. There is absolutely no reason why you can't last a full day with 30-40% left.
Well, first of all, it's just a phone, although an expensive one, so no need to be stressed.
Secondly, it sounds very much like you have a faulty battery or device. Maybe you should have replaced it as soon as you noticed the problem. There's definitely something wrong there if it goes from 100% down to 60% overnight (assuming it's not heavily used during that time).
You already tried most of the things that I would do to tackle the issue. Try swapping batteries for a few days with somebody with the same handset, and see what happens.
Good luck!
For giggles, why don't you hard reset your phone? Then, instead of loading tons of apps of questionable quality, task killers, memory managers, and battery monitors, just load the stuff you need everyday. Things like e-mail and social stuff. People that haven't tortured their phones with excessive crap seem to get better battery life without even trying. With over a hundred apps, all the syncs syncing, heavy Wi-Fi use, and Exchange push I'm now up to 14-18 hours with moderate to heavy use. If the experiment works, start loading the rest of your stuff on your phone to see what the impact is.
Another thing to consider is your network connectivity. Your carriers signal strength and infrastructure could be part of the problem. Certain carriers and locations seem to contribute a lot to batter drain. Also, the SGS2 is very router sensitive. It likes Netgear, D-Link not so much.
Good luck.
This is with a screen on time of 2:14 too, and overclocking to 1.52gHz
There is no battery issue, this phone has twice the battery life of the desire hd and thats a fact, i have not changed fast dormancy or anything, this phone is king for battery life.
Played games and browsed internet, i would say medium heavy usage
Using 2.3.3 KF3
Also if you had a laptop that lasted 10 hours with 63 remaining wouldnt you think that was good? This phone is the absolute top dog, i would even say its better than IP4 for battery now
Also used cardiotrainer to track my run this morning using GPS, ran for 30 mins and lost around 6 percent... Amazing!

Yep Juice defender sucks, and is not needed really...
You either have a rouge app sucking the life out of your phone,
Your syncing at too short periods (mine is set to 1 hour)
Your phone signal is weak so your phone is using more battery drawing 3g from your service provider
