Awesome battery

Ok i have posted these comments elsewhere. At the moment I have been lihjtly using my phone and it has been on standby since 1930 (10/2/11) and currently it stands at 80% charge at 1430 (11/2/11)
All I have done is turn flash to on demand (internet-settings-enable plugins- select on demand) I have also got the option to turn my mobile data usage off as well.
The idea came from a blog I was reading about macbook air and why Apple does not ship it with Flash, as it is this software that chews into the Macbook airs battery.
So i applied same idea to the DHD and Voila!

gonna give it a try
thanks btw

I'm trying this now and I've also noticed that apps are loading faster. Let me try the games...
Cheers from my DHD.

Hey....Nice one....Looks like the phone is faster now...Running CM7...can notice a visible difference...will leave it for some time to check the standby battery consumption

How did you turn off the mobile data usage ?

I used the mobile data app from the settings selection I think

Or you can go to settings > wireless. Or set up a widget.
Cheers from my DHD.

Not sure if I notice a difference but I'll report back in a few days time. Thanks for the tip bro

Something I know is the XDA app works better and faster. I don't know why its so...
Cheers from my DHD.

Have just turned plungins to on demand... not sure if it's just me but things do start to feel a tad bit faster/smoother...
What are the implications of changing this setting? Would browsing sites with flash take a slightly longer time to load?
Sent from my Desire HD using XDA App

Well I cannot say about speed difference as it may be anecdotal however, I have now put it on charge this morning as it hit less than 10%. So in total it has lasted 36 hours!!!
I will fully charge again and try leaving the phone with internet data on and see what kind of difference this will make.
Over the past two days I have surfed on the phone, downloaded several podcasts (Freakonomics) listened to them all and done all the usual things with this phone. It now seems to behave how my Iphone 3GS use to act when in 2g mode.
Conclusion:
Impressed and overall consistency of improved battery life is finally available if we follow the Apple way and get the Flash off!!!lol.
Sorry could not help myself

Where can i find the setting to turn off? I would like to try and see if the battery life is better but i can't find the specified setting?
Never mind, found it. Lets see if this does the trick? Thanks

Isn't it common sense to turn off Mobile Data when you don't need it?
No wonder people complain about battery life when they have every single setting and sync turned on.

will give it a bash now

Can anyone explain how to turn flashh off please.

Yup, This is a great post

With a web page open goto menu, settings, scroll to the bottom and change plugins to on demand. That's it.

I tried it but haven't noticed any difference.

Improved battery performance by turning off data roaming ?

Hi all,
Now I've not tried this myself however a friend of mine who recently got a DHD said he was lucky if the battery lasted a day on a full charge however by turning "Data roaming" off (even though he is not roaming) he is now getting anything between 2-3 days on one charge

Data roaming was turned off by default on mine and still the battery drained pretty quick.
Using data of any kind will affect the battery badly. Notes Traveler on my device is the cause of it needing charging every day.
Same as any phone, the more you disable the longer the battery will last.

If everything was implemented correctly by HTC, turning off Roaming should have no impact on battery life at all (provided you don't use Roaming).
I believe that your friend experienced the typical warm-up phase. For some (a lot?) people the battery life is terrible when they first use the DHD, but it gradually gets better.
Your friend probably attributes the increase of battery life to the disabled Roaming, while it is just a "natural" process.

I'm roaming all the time, and my battery is actually pretty good. If i don't use it much it can easily survive two days. My record is three days with light usage. (That was with the stock 1.72 ROM)

What is data roaming anyway???
Sent from my Desire HD using XDA App

Data roaming is set off by default. And data roaming controls data transfer when you are not on your home operator/network, i.e when traveling.

are your friend meant data connection?

He probably means "3G" off? I've had mine since the end of October and got into the habit of charging the phone every night. But then wondered about the effects of turning off wifi and 3G as, currently, I'm at home most of the time and have a PC with 24" screen to play with. Anyhow, with 3G and wifi turned off most of the time I get 3 days or so from a charge. I haven't investigated turning just one or the other off as life's too short ....

PS: and someone will say, well what's the point of a smart phone if you're just using it like a dumb phone? Well, the "smart" bit here in this case is me ....

Yeah, 3G uses a bit, so the first thing i did was to disable it. No point for me using it actually, since it's WiFi all over the place here i live. If i need it, i'll simply enough just toggle it on.

And btw 3g doesn't actuality use much more power when compared to wifi, if you always use it somewhere where the signal is always poor then it's another thing.

If I meant 3G then that's what I would of said. So just to be clear, there is an option "Data Roaming" that when turned on will enable a data connection when you are in another country. My friend claims that while on his home network he has turned this option off and he has seen a big improvement on battery performance. If this is true or not I'm not sure, I just simply thought I would share his thoughts with everyone else.

I did this, once i remembered where it was and I got my old battery life back. So thats a bonus, not having to take my charger to work!

Using System Panel graphs to monitor battery drain I'd concluded that 3G drains battery at about twice the rate compared to wifi.

Concerns about Xoom 4G upgrade (Verizon)

I have read some disturbing reviews about the Thunderbolt which is a 4G LTE Verizon phone. Although the phone itself sounds great, what concerns me are reports that the battery life is around 4-5 hours with 4G turned on.
So my question and concern is, once we upgrade the Xoom to 4G when available, are we going to be victims of the same poor battery life with 4G?

You're not required to have data connection on all the time. A toggle switch widget can fix the problem. Just turns it on when needed. But yeah I do agree that 4g and 3g will drain the battery.

I already keep my Xoom on airplane mode to disable all radios that I don't specifically activate. Seems to help with battery life. I downloaded some toggle Widgets to shortcut all the steps.

That is not really a solution. Currently with my Xoom, I can be on Wifi at home and when I am out, 3G kicks in. I do not want to toggle a widget when I need data (which is always) as I am sure most other people will not want to do. My battery life is totally acceptable currently with 3G and no toggling on/off. So will the 4G upgrade cause the battery life to be cut in half or worse?

I seriously doubt 4g will be much (if any) worse than 3g is now. The only way would be that you are on it more and keeping the screen on for longer times because it will RULE! lol

Just debating here but why do you think that? Why would Thunderbolt have a 4-5 hour battery life using 4G? You think that poor life is not 4G LTE related? And they have the luxury of swapping batteries which we cannot do with the Xoom.

I don't know how closely it is to sprint's 4g, but enabling 4g on my evo is a battery killer too. the good thing is that you can toggle 4g off and run in 3G mode. no need to disable data completely

Keep in mind, that the 4g upgrade will be OPTIONAL and if you are seriously debating whether the upgrade will be worth it or not, then simply don't send it in for the upgrade! The less people to send it in (like you), would in turn mean faster return time for my upgrade! I personally don't give a damn about having to click a toggle switch when I want to download at crazy fast speeds!
Just my .02
I can also guarantee you that 4g will have a pretty noticeable impact on battery life. And to be perfectly honest with you, the HTC Thunderbolt (stock), even with 4g turned off, still has absolutely horrible battery life.

Your response is very defensive and that is not the purpose of my questions. I am looking for meaningful conversation regarding the possibity that a 4g upgrade will significanty reduce battery life on the Xoom. All speculation but something to talk about.

So what I can gather is more or less around what everyone says. Get your 4g upgrade but don't turn it on and stick to 3g unless you feel you need the speed bump. So nothing will change except you know you have your turbo button-widget (yes old school) available.
That is unless it will be stuck on 4g at all times but looks like that is a feature that is toggled by today's hardware not permanent yet due to battery capacities.

I am not one to complain without reason but I certainly hope this is not the case.

MY plan is to remove the dummy card right before shipping it out so I can put it back if I am unhappy with the battery life.

In theory, 4g should use less battery, not more. 3g chipset firmware is highly optimized, though, due to the technology having been around for a while.
It may be a few firmware revisions to hit minimum use for 4g, but it shouldn't use dramatically more than 3g.

The answer for this thread is simple. Yes 4G will use more battery power, that's the short end of the stick. If you live in a 4G area and don't need the speed boost and would rather save battery there will be a way to disable 4G and use 3G just like with the thunderbolt or evo
Sent from my Evo using Tapatalk

It isn't speculation. The evo has a long track record with 4g of a very similar type. 4g will be a battery hog. But I never use it on my evo unless I'm tethered or streaming. Otherwise I find 3g more than enough for most tasks. I will send my xoom in for the upgrade. But I don't activate it. I tether it to my evo. But yes it will be a battery hog. Whenever you use cutting edge technology they tends to develop the speed and reliability first and worry about power consumption last.

I work for Verizon and honestly rarely hear many complaints about the battery life on the Thunderbolt. Many of my customers get awesome battery life and we have 4g in my area. The LTE radio does consume more battery than 3g especially if you are downloading a large file or something. Another thing to consider is the Thunderbolt is like a big brother to the Incredible and that phone had HORRIBLE battery life. The Thunderbolt has a much larger screen, 4g, and does not have a very large battery. I don't see 4g having a huge impact for most people but for those that feel it helps there will always be a toggle widget or “turbo button” like someone said earlier. I will definitely be sending mine in right away...

Sorry but you either live in a nice vacuum or a bubble or a cocoon because EVERYONE I know with this phone (friends, foes and customers too) loves it to death but hates the battery life with 4g on, and by default there's no way to turn off 4g when not needed.
Had to root for some friends and show them the 4g LTE off widget that came out the other day. At least that helps.
As for the Xoom, even if you might not want to use 4g or sign up, still send it in to be done. Definitely will help with resale value down the road.

my friend has the thunderbolt and the battery sucks, and he isn't in a 4g area. Mr verizon rep is on a feel good drug, or something.

It's going to drain more then the cdma radio does, at least until the technology and the software support behind it is more mature. But that is to be expected with bleeding technology.
Also remember that part of the battery issues on the TB comes from the fact that people use it alot more then previous phones. Streaming data is alot more power intensive then just the comparable occasional usage their previous device saw. I have a TB and if I use the snot out of it then yeah I can kill the battery in a couple of hours. However if I am busy and use it like I used my D2 or DX then I can get through the day without having to recharge.
Also you can turn just the LTE radio off when you are not using it if you are that concerned

Battery Saving Tip

Hey Guys,
Not sure if anyone has ever posted this but I thought I would share how I am able to get 2 days plus on single charge...
I only recomend this if you are not totally dependent on your email, facebook, gtalk, etc to sync.
I have my email accounts on my phone but I don't need to receive them instantly meaning they are not dire important so this works for me.
Android's biggest battery killer, which most of you probably know, is data syncing in background and just data connection in general. What I personally do is keep 3G data off at all times by going to settings->wireless and networks->mobile networks->3G Data and uncheck it.
Obviously with this off, you wont be able to connect to web, get emails, download apps, etc... But if you live in a 4G area like me, all I do every once in awhile is flip on 4G from dropdown let it sync or do what I got to do then flip 4G back off so there is no connection anymore... This will save so much of your battery but it is up to you to check things when you need to....
I hope this helps some people because it helps me a lot... I always recommend this to customers that come in my store if they are not depending on work email and such...
Let me know if you have any questions!

You can hold down the power button and click Data mode to toggle 3g

I have done those things since I've had this phone in august and everytime I talk about getting great battery life the haters come out and say well you didn't have sync on blah blah. Freaking retards. Especially if you are sleeping why not turn off sync for the email that is not going to come anyways. I haven't seen the battery life yet as I did since eclair though.

It didnt matter if it was OTA or OTW...
Maybe try and get a new battery...

I think the reasons the 'haters' come out is simply because you're stating your getting better battery life and then revealing you're castrating your phone. It is a smartphone after all. It's supposed to do all those things you turn off. This isn't a phone which is only supposed to make calls. I mean, if I wanted to check my email once a day, I'd simply do it while I'm in front of a computer.
I don't believe I'm one of said-haters but possibly providing a bit of information on where they're coming from as well.
I think it's well documented that Android phones pretty much suck in terms of battery life, especially when compared to Blackberry. Man, RIM got it right on that aspect.

How is that castrating your phone? I can still do everything else on the phone... You don't need a constant data connection to use it like a PDA. Do all tabs have a constant data connection? No, so are they not going to be considered PDA because they lack internet sometimes? no
I am sorry to say but if your managing your phone and doing things to better, that is not castrating, that is good device management and what should be done so it runs how you want...

Well, it sorts of like taking a porsche and not pushing it past 2nd gear. Some people are happy with it, some are not. On one hand, battery saving posts can be thought as misleading, if the premise is that you dont compromise any functionality. I prefer to charge my phone everyday and not worry about battery, but when your battery is dying when you need it in the evening, than one is of a different opinion entirely.
One thing which I realized to late, is if you are at work in the office or somewhere with wifi, you can toggle 3G off and not lose any functionality, since wifi uses a lot less juice.

I have tried I new battery, I have three that I alternate between. I have no idea what has happened to my phone. It could be the phone itself

Or they may find themselves not near a charger and almost dead and need their phone so turn off data to preserve the battery... I mean it doesn't "cripple" your phone to turn off data... I can still play angry birds, check my calendar, call people, text, etc. You don't need your phone to have data to use its features...

3G Drain on Jelly Bean

Are we likely to see a fix for this? We know there is a problem with 3G drinking battery but how likely are we to see a fix. Solutions like disable 3G aren't viable for a lot of people, so I just wondered what peoples thoughts on this were.

Try changing your modem. You should see a slight improvement in battery life, nothing major but still better than nothing.
Sent from my GT-I9000 using Tapatalk 2

Yeah a modem did help but I still had a big problem. Are we likely to see a fix, I remember this being a problem with ICS which is why I reverted back.

Its not the modem. My phone stock uses the XXKG3 modem, and i have been using that on ICS and now into JB. Jellybean definitely has worse battery concerning 3G / H for some reason. I just barely squeeze a day out of mine.

Yeah, I was struggling to get even a day. I tried almost all of the Jelly Bean ROMs and they all suffered from the same problem. I really wanted to stick with JB, especially C-ROM because it was like a dream to use but on a good day I'd get about 7 or 8 hours maybe? I would always have to plug it in twice a day. Currently trying SauROM which is better but I'm starting to think that the best for battery life is genuinely a stock rom like JVS.

On Jelly Bean?

did you limited your speed to 3g or do you also use hsdpa? if you use hsdpa, give 3g a try i think the battery drain in 3g is a lot lower ... in my opinion if you are not downloading 3g is fast enough to browse or youtube.
for just instant messaging you can give 2g a try

2G isn't really usable on Three mobile.
I don't know how to limit to just 3G. But yes I normally use HSPDA. That said, we should be able to use it without draining our battery

I'm not getting any major battery drain here. I can last a full day on HSDPA and or WiFi.

You CAN limit to just 3G. You have to go to Advanced Settings or Galaxy S Settings (depends on a ROM) and go to HSDPA and put it to UMTS mode only. It'll switch it to 3G and will consume less battery

in my opinion, thats the point, go to settings/advanced/RADIO in your case hsdpa + hsupa should be ticket, simply tick umts an you should notice, the changing radio icon in the status bar (no longer h, but 3g).
your 3g and hspa power consumption depends really strong from the signal strenght and in your phone is connected constantly or changes often. bad reception causes a large waist of battery power.

My guess is you have Google Now / Maps running in background which always uses your data.

On slim 2.9, I found that removing G now, and turning off all location tracking increased battery life. Now I can get a day and about an hour/90mins of screen on time with data/wifi only on when using it. I suppose after more than 2 years of use on the one battery charging every day or more, there's only so much one can expect from a device and battery.

But isn't it recognized that this is a problem? The 3G Bug? Nothing to do with Google Now etc

in my opinion thats not enough, do you mean 24 hours or 16 hours? could be a little more with 90 mins of screen time, but you shouldnt need more.
inverted apps can by the way help too, avoid white and light colours as background
