Could someone help me troubleshoot/fix my cell standby issue. I know it's been asked before and I apologize if this upsets you. But, i have searched and tried methods to fix the issue with no success. And it just kills my battery.
I've used many roms and initially would always have 50-70% cell standby. With the airplane mode fix i could only get it to drop to 20-35%. I'm on the Aloysius rom now which isn't supposed to have any cell standby issues and my cell standby is still 45-60%. With airplane fix I get it down to 15-30%. I can never get it down to under 10 which would at least make me happy. But, from what I've read most get it down to zero. I would appreciate any suggestions or ideas to help me fix this problem. Thanks
I think alot of that depends on your location... Cell standby is not a bad thing, we just don't want the bug that makes it sit at 50% every time I restart my phone. Mine fluctuates between 0%, (when im downtown with full bars all the time) and 25%, (when at home with only 1 or 2 bars).

Yeah I commute from sacramento to san francisco every day so initially I blamed that. But even when I'm in my house with full bars it's up around 30% always. Not only does this waste battery life, but i would assume, possibly incorrectly, that this also slows down the speed of the device as well as it's being used to find a signal. Ugh
It may not be that big of an issue... Or at least as big as i think it is. But, i would think that with the limitations of the battery and processor that this would just make things even worse. It's just a nuisance that people can get theirs to zero and I have never gotten it that low.

When at work, i have very little, if any service. But at home, I have full service. So I will have to see if it lowers when I get off work tonight. But I am always around 40%+

Thank you for that. It makes me feel a little better to hear I'm not alone. Have you tried the Aloysius rom? Supposedly it fixes the problem for some.

I am using v6 of his ROM. I still get better battery than any other ROM I have used, and trust me, i have flashed almost every single ROM. But since seeing others with very low, I was just wondering as well.
OK well something weird is happening with my time without a signal... I am at 65% right now and already did the airplane trick... and it just jumps up.... that being said... My battery life is still way outlasting anyother ROM and to top it off, I am getting a signal and am making calls in places at work where I did not have a signal at all.... not that I care much about the time with a signal % because this ROM is the best, but its just weird... better battery performance, better signal, higher stat.. hmmm

I have a similar issue... I posted this in the other thread
Gizmodo and MobileCrunch have pretty much bashed the battery life to make it sound like if its not on the charger, it will die in a matter of an hour or three. For the people who got one from the I/O or other means. What do you get from the phone during a normal days usage? If its that bad, have you guys use SetCPU/Locale/App Killers etc? Thanks.
With light to moderate use, it lasts through the day. A bit worse than Nexus One in that respect, but not too bad.
Agree with sergey.povzner.
Android central had a great review on this. I have heard a mixed bag of battery life. Some sounded very good some didn't. But it's the most power smartphone out there so additional drain is expected.
http://www.androidcentral.com/review-sprint-htc-evo-4g-android-smartphone
It not as good as my n1 but its close. It gets a lot better with custom roms without sense.
Uptime 10:08:35
Awake time 1:46
I had it plugged into computer for about 25 mins to transfer a movie.
I have 80% battery left.
No bluetooth, no GPS, no WIFI.
I don't have anything extra except gmail and another account frequently syncing. I get 4-5 hours of browsing and email with 4g on or off, wifi off, gps off. Standby time doesn't seem to have significant effect though I'm sure it would be measurable if you left it in standby for a day. Adequate to get me though a day, but I hardly use voice.
What if you are watching full length movie on HTC Evo, how long will the battery last (especially if I put it on airplane mode)?
I am planning to switch from from Xperia X10i to HTC Evo. My x10 has the usual battery drain problem but I have controlled it with task killer. However, I am yet to run a full movie on it. If x10's battery life has more survival time (with task killer on it of course) then HTC Evo then I might think twice.
Also can the 'task killer' improve HTC Evo's battery life?
Does anyone know if the Evo uses the HTC Touch Pro size battery like the Hero?
If so then I've already got an external charger and three extra batteries!
Honestly if anyone is that worried about battery life get another battery as a backup. Its been said many times on these forums that a HTC Touch Pro 2 and also a HTC Hero all use the same batteries as the EVO. (Confirmed). You can pick them up on ebay for around 7 or 8$. Which is pretty cheap! Nothing better than having an extra juice pack laying around waiting to be used! Hope this helps somewhat

i'm so excited, wish I had an extra battery though, it'd be nice
8hrs 15min till i get mine!
Gotta say this thing blows my old Moment's battery out of the water... 4.5 hours hard and heavy use... 60% left - no 4G coverage area (but it was left on by accident - ooops) and no video watching, but heavy text, email, and facebook/twitter activity.
I ordered the extended slim battery from seidio.com. 1750 vs 1500. Should give a bit more in the long run.
Its been decent for me though. Just dont jack up your brightness, keep it on auto.
Wifi kills my battery. The signal never settles even though the coverage should be good all over my house.
You want to go into advanced wifi settings and change WiFi sleep policy to never otherwise your phone will shut off WiFi after 15 mins of screen being off and you'll be using 3g which will use a lot more battery.

Mybattery was pretty terrible. Lose 10% per 40 minutes on standby mode alone. After messing around with it for a while I discovered the culprit was the location services. I turned them off and now I lose about 2% per hour on standby.

I'm curious, how exactly do you go about turning off the location services? Unless it's included with the GPS tab of the settings, I haven't been able to find such an option on my brother's Hero.

It's under settings , location and then location setting. This does not disable the 911 location which is good.
Okay, so WiFi is usually better than 3G when it comes to battery life; but what about WiMax? I don't have a stable signal yet so I can't reliably test the two. What are ya'll experiences (for those within a reliable 4G area)? Better, the same, worse, or a lot worse?

I don't have reliable 4G in my area, but I notice that even turning on the wimax 4G radio dramatically drains my battery. Don't know if its becasue its constantly searching for signal or just becasue the radio is turned on. My 2 cents, but I know it's not very thorough..
Any time you have a radio turned on and do not have a signal it will drain the battery trying to find a signal.
If you go to an area with poor 3g service, your battery will drain crazy.
They are testing 4g in my area, so it is up and down a lot, so I cannot test.
From reading other posts, I believe 4g may take slightly more battery.
Since Froyo has been released, the 4G battery drain isn't nearly as bad as it was on 2.1. I've noticed that the speeds have substantially increased as well as better battery management as well.

Yeah, that's why I wanted to see how things are now. We all know how 4G got slammed by reviewers for killing the battery, but the new radio might have changed that. I'm just curious at how it compares to 3G now under ideal conditions (good signal).
I have full 4G coverage where I live and to be honest when 4G is on, the battery drainage difference is not much, when compared to 3G.
I have 4G in my area as well, but I leave it off because it goes back and forth from being connected to not being connected. I did notice last night that my battery went from 70% to 5% over night... Anyone know what could cause that?

I have the same problem. I'm in the Baltimore area and the 3G/4G switches back and forth. I figured out that when the phone isn't in 4G, it searches for a 4G connection, but you can put it to 3G only (with an app called Phone Info) until Verizon is done with their 4G coverage.
4G uses more power than 3g, which uses more power than wifi.
4g<3g<wifi.
it's significantly worse on 4G, so much so that I have an extended battery and I still don't use it.

I live in Idaho. Sprint advertises that they have 'mammoth coverage' around here, but they're wrong. They don't. Well, they have coverage (except for my house and office) and the 3G/4G speeds are usually complete **** unless you're within sight of a tower.
Data from the towers out in Caldwell haven't worked for over 2 months and Sprint claims that they're working just fine and have recently been updated - apparently they updated to dial-up. I really wonder how they're even selling phones over there right now.
Idaho = Battery life is usually 5 to 10 hours with normal usage.
2 weekends ago I was in Omaha and used my evo a little bit less than normal, but I could get through the whole day and still have 50%+ battery life left. The 3G speeds were also 2x better, as well as service in general.
I think it depends on where you're located and if sprint has maintained/updated their towers. I also think that most of the towers in Nampa/Caldwell (20 mi. out of Boise) are older nextel towers, which are probably complete ****/half working.
Just my theory.
Sounds plausible, but I have no idea scientifically speaking. I could guess but I don't think it would be productive.
My honest suggestion? Post this over at the dslreports.com forums; there were some really knowledgeable people lurking there.

I agree. In addition to rogue apps/processes, it seems that weak network is #2 on my list of things to check when my batt life is draining too much.
This isn't really a theory, it is fact. If you have bad coverage you can basically watch your battery drain. I could drain mine dead overnight by leaving my phone unplugged and in the basement.. I had 1 bar of roaming service. I now hqve an airave and battery life drains much less overnight.

ive had my batter die in 3 hours because of no service. I watched my battery go from 70% to 30% in 1 hour because of no signal. Since I'm not running CM6 the roam control app has been well worth the couple of bucks. No more missed calls and far less battery drain when im in low signal areas.
Poor 3G low signal is the biggest battery problem for Android!
Android (not the Evo but the entire OS) has a very poor system for dealing with Low Signal for 3G and it does NOT automatically switch over to 2G when it's supposed to which CAN and DOES result in greatly increased battery life.
Other phone OS's do this or are supposed to do this but for some reason Google has just not implemented a good system for dealing with this COMMON issue.
I use a program called JuiceDefender (Paid version is best but the free version will prove to you how useful it is) and it is literally the best app I run on my Evo. Overnight I went from my phone dying by 4pm when working at a location with low signal to having it last multiple days in some cases depending on my usage.
Do yourselves a favor, Get this application and if you have your phone rooted you get many extra features out of the full version. Can't speak highly enough of this application.

I agree with that and know that when you have 0/1/2 bars it really drains your battery life, however, I get the same battery life if I'm at home all day using it (0/1/2 bars), or if I'm at college and have 5 bars all day and I'm not using it quite as much.
I have fresh 3.3 with the htc kernel 53 fps (and all the latest radios/pri/prl/ect.) and have seen much improved battery life, but it's still the exact same.
I also have an airave at the office (which is out in Caldwell where the data doesn't even work) for the other two people on my plan, and while they have seen slightly less battery drain since we got the airave (for free), it's not a mind-blowing difference, other than the data actually works. They're also running the 2.1 stock, but rooted with unrevoked.
I guess I'm wondering if staying connected to a tower with older tech/Nextel uses more power than if it's connected to a sprint tower.

There's no way your Evo is working off of any Nextel towers. Those are IDEN and your Evo is CDMA...not happening. It's been known for years now that if you have poor/no signal, your battery will drain rapidly as the device will constantly search for a better signal.

Good to know - How do people get Sprint Phones to work on Boost mobile then? Boost is using nextel towers, or that's what I've read several times.
I agree with that and know that when you have 0/1/2 bars it really drains your battery life, however, I get the same battery life if I'm at home all day using it (0/1/2 bars), or if I'm at college and have 5 bars all day and I'm not using it quite as much.

You're half right. Boost does use nextel towers--For iDen phones. They do use the Sprint network for CDMA phones. Basically boost carries both CDMA and iDen phones.
As for how people get Sprint phones to work with Boost(CDMA)... Hm... Let's just say they do something shady and possibly illegal...They clone ESNs.
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

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
