Official Froyo battery life thread

Wanted to start this so we can get a better idea of what kind of battery life we will be seeing with 2.2! Please post your opinions so far and if you are rooted/stock and using stock kernel or the .34 kernel cyan posted. Hopefully we won't see much of a decrease do to JIT or any other new features

Probably won't be that great the first couple of days...testing out Flash and everything...(watching Hulu right now).

i was on CM5.0.7t2, and as we all know, CM is known for draining more battery than the stock rom/enoms but so far im seeing same usage as CM which is ok but not great. next few days will be testing for all of us. hopefully we will have similiar usages not like before where some people are getting 40 hours and some 10 lol

I dont if theres an improvement but I updated on a full battery. After I had 97% then killed the battery in like 5hours while at the Engadget Show lol

is anyone running setcpu with FroYo? im already gettin horribad battery life...probably due to Hulu

I may have done something wrong, but I'm on a rooted phone with kernel 2.6.32.9-27220-g328f560 and my phone went from 80% to 10% in about 4 hours just sitting in my pocket. The most I did was check some emails and some basic SMS.
Will monitor closer tomorrow by my battery usage shows something like 19% email. I wonder if my outlook push is doing something constantly that is hurting it.
Edit: it's also charging REALLY slowly. I have it connected to a USB port and its taken ~ 30 minutes to go from 14-16%.

So far, mine is looking pretty good. Early days yet though.

Its better with froyo.
Had to charge every evening with CM 5.0.6 and pershoots kernel, now i get almost a half day more (with more "playing around").
I use setcpu (245/499 at sleep).

My battery is showing 99% after 3 hours switched on and with light usage. If true, that is amazing! More likely something is not quite right. I am using the .34 UV kernel from persionsown he posted on twitter....

The Jones.. gotta try that Kernel..

If I believed that it were a true reflection of battery use and not a mis-report of some sort, I would be shouting about it a lot louder!!

i streamed about 1.5 hours of video via qik (uploading not DLing). Still have 60% battery left. I say that's an improvement. Rooted modaco froyo

I'm seeing what I think is significantly worse battery life since I installed Froyo. It's hard to say, though, because I've been playing around in ways that are different from my normal usage pattern (checking the market frequently for updated apps, for example). I was on stock 2.1update1 and now am on stock Froyo.

Battery life is definitely better than Cyano/Modaco/Enomther but it is also worse than stock ERE27. Can definitely make it through a day still though on moderate/slightly heavy use with Froyo something I can't do with Cyan/Modaco/Enom...and this is way faster and more fun than any rom i've had previously so no complaints from me.

Well I was running cyan 5.0.7 and it lasted me longer than this I have now, which is Paul's Froyo.. but since my wi-fi finally stays on I wont revert.
Question: can I still install older custom kernels on froyo???. Want to try...

My battery died sometime last night, and I had gone to bed with it 70% charged. Prior to Froyo, I was on CM 5.0.6 and usually using intersectraven's 925mv kernels, and I would lose about 1.2% per hour while idling.
I'm not blaming Froyo yet, since it could have been an app screwing around. However, the battery usage page didn't show anything out of the ordinary. It will take some more testing before I ditch Froyo until an update is released.
BTW, battery usage while actually using the phone seems to be about the same.

my battery life was phenomenal today. i can't give percentage, because i haven't put on a battery widget (or many widgets at all, tbh), but stock froyo treated me well. was above 80% (guessing by icon) when i left work after 8 hours, some hulu, some wifi, some texting, some phone calls. not exactly heavy usage, but not just idle either.

Check out Battery Indicator http://www.cyrket.com/p/android/com.darshancomputing.BatteryIndicator/
Great and extremely simple app. I've been using it for months. (And it doesn't drain battery either.)

JI6 update: a *serious* let-down, in my opinion

So, this post is 1/2 "rant" and 1/2 "any ideas", but the JI6 Update has been (in my opinion) a very serious letdown.
First of all, I can't be alone in thinking that the late-September update from Samsung would be a full-blown upgrade to Froyo. Obviously it's not. I guess we'll wait awhile before that's released
Secondly, I'm one of those sorry saps that had the update soft-brick my phone. It took me a few days to get around to the ODIN fix (bumping me back to "stock"), but it was still a royal pain.
Thirdly, I've already seen some issues that I didn't have before. For instance, the phone "froze" on me while sitting at home: no screen response. I had to pull the battery and power up again. Nice!
Finally, the battery life is utterly horrible for me -- and I'm not sure why. Currently at 26% battery life (now 8h 4m since unplugged). 34% of the usage is "display", which has been on for 28m total. 22% is cell standby. 15% is phone idle. 10% is voice calls (2m 10s of that). 8% is the Android System. So on and so forth. Basically, I've *hardly* used my phone today, yet the battery isn't going to last thru to the afternoon. I have 6 active applications, with none of them hitting the CPU at all currently. Best of all? The battery icon looks like I'm about 1/2 full, so evidently Samsung couldn't be bothered to make that icon accurate. I know about the battery icon mods out there (I've used 'em), but I figured Samsung would take care of that.
Sorry for the venting, folks. Is anyone else seeing similar stuff? Any ideas on the lame battery life??
Thanks,
Yip

For me Android 2.1 which samsung released in Galaxy S is exactly like Windows Vista ! No matter how many updates you release for it still will make your phone **** !
The only option is to release a full new OS which is Windows 7 = Froyo !

Better than Windows NT = 1.6

Getting your phone bricked isnt the updates fault, there are hundreds of threads out there and reading just one couldve given you signs of warning.
As for your battery life, I am willing to bet your phone screen is full of widgets. Try limiting those, as well as automated syncing. I get excellent battery life that can EASILY last me the whole day (I actually find myself running avatar/pandora at the end of the night just to drain it so I can recharge the battery).
However, I do agree that the inaccurate battery reading should have been fixed a long time ago (or at least in this update) and that froyo should have been included with the release of this phone.

Your cell standy is too high which means you have things constantly using the cell signal to pull data, thus draining your battery. Right now I'm at 72% with 67% display, 14% voice calls, and 9% cell standby. Been unplugged for 3 and a half hours.
Not great but I'm purposely trying to let it die because I'm reconditioning.

Ha! You may just be right on that. Eclair seems like a fairly lame version of Android, if you ask me. Not horrible, but not great.

"Signs of warning" means nothing, my friend. There are folks who didn't even *root* that got soft-bricked with this update. It was (somehow) poorly handled.
As for your widgets comment, well... you would've lost the bet. I use a single screen, no widgets, no weather stuff, bluetooth off, wifi on (but currently turned off), and nothing extraneous. I run Android about as light & frothy as you can get! I prefer speed over just about everything.
Any other thoughts, though? Perhaps I should re-load Autostarts to see if there's anything strange launching at boot time...

Interesting. Any ideas what would be pinging the cell standby so much? I'm in a high-bandwidth area (full bars), so it's not like the phone is struggling to get signal. I use Gmail and Exchange, but my Exchange sync is set to "hourly", rather than push.
Doesn't seem like I'd need to disable my 3G connectivity. I certainly have never had to before.

You should probably reflash the update. JI6 was great on my phone, no hiccups, no lag, perfect GPS.
Also, you should recalibrate your battery after the update and give it a few days to settle down. I always get horrible battery life after flashing a rom, but after a few cycles I'm back up to 24h+.

Honestly, I wouldn't know unless I knew your full setup. What I will say is that I do have a lot of widgets and apps running that pull from the internet but yet my cell standby isn't as high as yours. I haven't reduced any of my sync intervals either. The 3G radio can really drain battery fast, faster than even the screen so that is a problem.
Also, in JI6, they increased the strength of the radio so it drains even more battery. I am running the JI6 modem however.
You should use something like WatchDog to see what is constantly running and using CPU. That could give you an indicator of problem apps.

Well, I'm disabling some startup items: Visual Voicemail, Telenav, and Daily Briefing -- none of which I use. Maybe that'll help. I don't know...
I was really trying to run "stock" this time around -- not so much fooling and tinkering with things, but it doesn't appear to be paying off for me. Frustrating.

Oh wow, yea definitely you need to disable all of those. That's the first thing I do. I actually uninstall Visual Voicemail, Telenav, Amazon MP3 etc. ALL of those things constantly run for some reason even without you opening them once.

You're not alone. My battery life is terrible as well after the update. I'm losing 4% an hour on standby.
That said, my phone is smooth and working great when I do use it.

Amen to that. Except that the GPS is still unreliable.

I'm having terrible battery life as well.

i'm 24 hours unplugged, sitting at 27%
all stock JI6

Again, if you didn't do so after the update, wipe battery stats and then do a few full drain/charge cycles. My battery life always sucks after flashing a new ROM, but it always goes back to normal given time.
Sent from my SGH-T959 using XDA App

after the update for me, my gps is much better, but i actually have more lag then i had stock before....
so I need to either flash a kernel, lag fix, or a rom with at least one of those.... its kind of frustrating to have lag just from opening or closing a simple app, messages, or call... I honestly cant believe a phone with these hardware specs can have lag just from somthing as simple going into the dialer and exiting out...

Battery life seems to have decreased a little but still getting a good 20+ hours. GPS is a little better with use wireless networks. Lag is an issue now though. Didn't have much before a the update. Hopefully its solved in another update or froyo.

So I applied the update on Tuesday through Mini Kies. First experience with this update, it's been great. My phone seems to faster, really I hardly experience any kind of lag or slowdown (and this is in comparison with my stock vibrant running OCLF). Battery life even seems to be better, but that is probably to do with conditioning. So everything has been good except for the fact that my phone has froze on me TWICE today. I'm thinking it's something to do with the apps though. I was in Layar and it was working for a bit when suddenly, it froze, I didn't have to pull the battery I just held the power button down for a good 5-10 seconds and it restarted. The other time was in a game, which kind of concerns me. I suppose I can reinstall both and see how that goes. I'm thinking it has more to do with the apps possibly being corrupted. The first thing I did was install the 2.2 market on my phone and I ran the update all function on like 15 apps that needed updating. Not a good idea imo, the market went crazy and forced closed a couple of times. I'm not entirely sure what is going but it seems like my phone is only freezing in certain apps. I hope it's not just some random freeze that can happen at anytime, that wouldn't be no good.

You guys complaining about battery life... i would Love to have your times. I got 3 hours and 8 minutes today on a fully charged battery.

Yet another battery issues thread

Yeah I know there are a lot of other battery threads out there, but just wondering if I can get some help from all you gurus.
Currently running MYN Warm 2.2 RLS3 with HTC kernel 2.6.32.15.
Have read a lot about this and done a lot of the usual optimizations (calibrate battery, turn off auto sync, 4G, etc...last test I did I was able to get about 25 hours on a charge with very little usage, which is pretty decent. So the phone seems to be sleeping the way it's supposed to.
The issue I have is that when I actually start using the phone the battery drains like crazy (about 1% every two minutes). This is with regular usage (i.e. internet browsing). If I use certain battery hog features such as Navigation or Bluetooh then it drains everything in a matter of an hour or so. Have tried playing around with SetCPU and don't really see any improvements (BTW I only get three options on SetCPU).
So the question is whether the battery drainage is a function of the Kernel I'm using? Why would it be good when it's sleeping, but as soon as I use something consumption goes through the roof. Is there anything out there that would allow you to see actual battery usage by app or service? I know Spare Parts gives you SOME info, but it's not granular enough (i.e. It says Android System includes many different pieces).

I doubt there's any magical kernel that can do more than what you are getting now.
Best you can do is to make sure the phone sleeps when the screen is off, which seems like you have already.
Max display on usage I usually get out of a charge is between 2-3 hours at about 30% brightness settings, out of about 12-15 hour per charge.
I sync google, always data on.

yo i have myn's rom as well but different kernel.. try the ones that myn added in the myn update app that came with the rom

Hmmm...so I guess 2-3 hours of actual usage is the best I can hope for then? I hear people saying how they get a lot of hours and that includes having Bluetooth on, browsing the web, Pandora, gaming, etc...If I did that with mine I don't think I would get more than 45 minutes.

You probably can extend it by using wifi but what's the fun in that?

Hmmm...Where? Are you referring to the Warm Updater app? I don't see anything about other kernels there. I haven't flashed any kernels on my phone. This is the one it came with.
What battery life do you get when you're actually using the phone?
Achllles: I get quite a bit of degradation on WI-FI as well.
I'm just trying to understand if there's a way to see what exactly is eating my battery when I use the phone. I mean I could be just sitting on the screen not doing anything and if it's on it consumes quite a bit, but as soon as I turn off the screen everything goes to sleep and consumption drops to about 1% per hour. just trying to understand this huge disparity.

Not sure. Best you can do at this point is to install current widget and see how much is being consumed, and guess what's killing your battery.
One other thing I've noticed was even at same settings, my phone often consumed around 25-30mA while screen is off, but now it hovers around 50-100mA, and I haven't made any change to the phone.
Not sure if it's effect on real life usage, but it does seem like it does.

Maybe its not software related...maybe your battery is just shot already.

I know exactly what your going through OP. This caused me to leave Myns and Cyanogen and go to Fresh ROM.
This seems to have mainly fixed the problem.

Myn was using the stock kernal, but his new rsl4 is gonna be using ziggys elite kernal.. Now is this kernal gonna be faster than other ones? No but myn told me its not about speed. Its speed that makes your battery life go down. These flashy kernals that have high quadrant speeds, suffer battery draining issues. So wait till friday for the new rom, and see how that goes.

there are 2 kernels there.. just try to look harder, i get 12-15hrs heavy use which is more than enough for me

Was never able to find these other Kernels, but I did install Netarchy Toast. Installed versions 4.19 to try Collin's Battery Tweak, but could never get that tweak to work properly (it always has a process that uses a lot of CPU). Uninstalled that and tried version 4.2 ant that seems to be working OK (without the battery tweak).
So after a lot of testing and re-testing I've come to the conclusion that my crazy battery drain only happens whenever there's a "radio" on. CPU usage is not the main culprit in my case as even overclocking it doesn't drain it much if the radios are turned off. It doesn't matter if it's WIFI, 3G or 4G, if the phone is using any of this it drains very quickly. Thus the reason it acts good whenever is sleeping.
A perfect example of this is that I used Power Amp to play music from my music library (from my SD Card). Used it for like 4 hours and it drained the battery at a very reasonable pace, then I stopped that and started playing music using Pandora. Immediately the battery started to drain at about 1% rate every two minutes or so. I've read somewhere that using WIFI instead of 3G would save battery. Didn't seem to make a difference in my case as it drained at about the same rapid pace. Now if I have both on, then it gets even crazier.
So having found the culprits the question is whether there's anything that can be done to improve this. BTW I think I have the latest PRI (1.77_003), PRL (60671) and baseband (2.15.00.09.01) versions

Appropriate steps to a better battery life?

Hi everyone! Long time XDA reader and I've had my Evo rooted for months. Now I have been dealing with its "poor" battery life for a long time and not really thinking much of it till I finally decided that rooting has to have some advantage for this. I average about 6-7 hours then my phone dies...
After doing a little research I read some people getting 15-20+ hours out of their phone with heavy use...I was amazed...I decided to try to get better battery life on my phone and this is what I am trying right now. I just want to make sure I am on the right path with it and that I am not doing anything seriously wrong.
-I am trying Cynogens ROMs - CM7 I tried for a day and that gave me about 7 hours of battery life...still no real improvments. I am trying Cynogens 7 Nightly 12 now to see if that works.
-I am trying different Kernels. Been getting them on the HTC EVO kernels page. Right now I am using stock HTC one.
-Should I try different radios too? Where can I go to find different radios if so.
-What order should I be installing radios/kernels/roms?
-I have donated and am using Set CPU now also and have the screen off cpu power really low.
-Am I on the right path trying out different ROMS/ Kernels/ Radios to optimize my battery life? Is there anything else I can be trying?

turn off gps when not need
data when not needed

Check out my sig for my full walk-through on battery life (I don't want to repost it here lol).
But you seem to be doing everything okay. My only hesitation would be to say make sure you're giving Kernels adequate time to settle into your phone. Unless something is HORRIBLY wrong with them, you shouldn't switch/judge them until at least two days in
Radios should not make a difference in your battery life.
Also, be aware that CM is NOT optimized for battery life. There are a couple of ROMs that will give you unheard of battery life if you would like though (Myn's comes to mind). It's a trade off though. CM is hands down the fastest ROM you'll run...but in my experiences is in the lower tier of battery.
Hope that helps

also when the newest version of ultimate Juice is released that will help you i have the closed beta and im glad to have it back and running

@Cheesy: I turn off all those things If I turn off "data" that turns off Exchange push right? I really need that on all the time >_<
@Green: Really? Myns is good on battery life? I tried that before and was dieing with battery. (Was getting my average 6-7 hours) I had that one for about 2 weeks. Do you think it was my Kernels that were bad then? Isn't Myns warm 2 pt sense based? The one I used was...I had thought sense UI drained battery more than CM for example that is just plain stock android gingerbread?
@Cheesy again: Ultimate Juice? Is that an app on the mkt place? How much did it help you? I'm willing to donate and pay for apps to support the devs if they really make a noticeable difference.
Another thing..when you install a ROM does it automatically install a Kernel too? Or are those 2 separate?

with UJ i get 18-19 or more on a full charge with phone being used 80% of the day .
with out i was changing out batteries after 9 hours or so ( i normally work 12 - 13 hours a day )
yes its in the market but gingerbread support is not public yet ( closed beta )
also check in spareparts for any wakelocks you might be having
for a sense rom myns are great so are Ava's,caulkins and Miks

Hmm Thanks Cheesy. I'll take a look at that.
So if I flash a ROM that is not Gingerbread...I can use that app. But Gingerbread is anything 2.0+ right?
I'll try out those ROMs too and different kernels...test them for 2-3 days.
Whats wake lock? I'll download that spare parts thing and see if I can figure it out.

I just recently started seeing great battery life with my rooted Evo. I flashed MikFroYo 4.5 with a stock htc kernal.
I use juice defender and that's it. I've been getting just over a day per charge for the past two weeks.
I wouldn't say that's with heavy use as a good 6-7 hours of that time are accounted for when I'm asleep. I do about 30-50 texts a day. About 10 minutes of calls and I check facebook and twitter all the time. My data use varies depending on the day but I do use youtube and pandora pretty regularly as well.

just make sure background data is disabled. accounts and sync>background data. I have no issues with battery life on stock sprint evo.
of course it is a 3500mah battery

My wife and I just bought two EVOs a week and a half ago, and I quickly became interested in improving the battery life on the phone. My first attempts were rooting my phone and installing OverClock Widget, and using minimal settings when the screen was off. With that change alone, and comparing to my wife's phone from a full overnight charge, my phone was able to make it 14-16 hours with moderate use. My wife's phone would die after 8-9 hours of moderate use. Granted, there's obviously going to be a difference between my moderate use and hers, but even testing with screens off and letting them idle for an hour, there was a definitive difference in battery consumption between our phones.
I went one step further and installed CM7 Nightly 12 just yesterday... already I'm noticing even further improvement in battery life, but the majority of those savings are when my phone is idle. Overnight, my battery only drained 7%, whereas my wife's drained much more than that. My battery has been at 39% for the past 3 hours at idle, so I imagine that with my version of "standard usage", I would be able to possibly get higher than 16 hours of usage per charge (can't wait until I do the full calculation testing tomorrow!).
Here are some observations I've had in all of this:
1) Check out Greenfieldan's list of battery tips and tricks. Some of these are very simple and actually had a significant impact on both my phone and my wife's phone (especially shutting off data and disabling auto-synch). I'm new to the forums, but this is one of the first things I checked out. This is a great place to start.
2) Battery consumption is obviously affected by how frequently you use your phone, and what you are doing with it. I say this because it's easy to read threads about what techniques work and see mixed results, but I don't see alot of people really admitting how much or how little they use their phones. I'd say I'm a more conservative user of my phone, but I still have my texting, browsing, and even occasional streaming, GPS using and general fiddling. So in other words, your mileage may vary with any given technique.
3) This is my personal opinion, but think about when you ideally want to be charging your phone, and try and anticipate usage around it. It sounds strange, but I've come to my own conclusion that an optimal charge for me (not necessarily possible, but optimal) will give either 12 or 36 hours of usage time. This is because I like to charge my phone overnight, so if I get 18 hours of battery life, I'm unfortunately wasting 4-6 of them. If I get 24 hours of usage, then that means that by the next morning, I need to charge again. So I plan ahead and charge at night, and use through the day. This was particularly useful when I first started with the phone and was getting a max of 8-9 hours. I'd know when to unplug, and how well it would get me through the day.
Anyway, at this point I'm rambling, but since it is still very fresh in my mind I wanted to share my thoughts. Hopefully this helps.
(Btw, apologies for the huge post!!)

Anyhow, from my testing on mine and three other phones Myn's Warm TwoPointTwo has the best battery life (although some of them were right on par with it). Specifically his RLS 3 and RLS 4. Did you try Warm Z? Because the battery life on that ROM is no where NEAR his 2.2 ROM.
Also, Sense CAN be a major drain on battery. If you make it so it's not syncing all the time/doing the random shenanigans it defaults to I'd argue it's better than AOSP (based on my experience with both).
Yes, your Kernel might have been an issue. Do you know which one you were using? HAVS? CFS? BFS? Etc.
Just for my phone comparison, CM7 (which I am running now) requires me to charge my phone at least once a day. Myn's Warm TwoPointTwo was every other day/every day and a half.

You can set juice defender to turn on data to sync at set intervals; anywhere from 15min to every couple of hours. If you can stand to wait 15 minutes for that email then I would recommend it. I personally like not being interrupted every time I get an email.
Also, make sure your kernel and setCPU aren't trying to both control the same thing. I really like using a kernel with HAVS so I avoid apps that also try to modulate my CPU.
I've tried warm 2.2 and really like it. Although I think I'm getting slightly better battery with Azrael X 4.0 with netarchy 4.3.1-cfs-havs-nosbc and ultimate juice controlling only my data and WiFi connections.
Also,the 3500mah battery is worth every penny if you don't mind the extra thickness.

i owe setcpu and screen off seting for my battery life

I read Greenfieldan's step on the forum here about a week ago, and jsut the HTC Method of battery calibration alone changed my battery life completely.
I also dumped Advanced Task Killer.
In another thread, I rad that CM is the worst drain on a battery and I personally think the guy that wrote that is sadly mistaken. Even with all the steps taken in Greenfieldan's guide, Sense based ROMs are battery killers. They are the worst, by far, and I average battery drain at about 15-20% pr hour, even with screen off.
The #2 killer, is having your screen on. Waiting for that next text to come in with the screen on is not worth it, so turn it off when you're not using it.
With the setup in my sig, and moderate to heavy use, in 12 hours, I only drop about 25% with a Sedio 3500maH battery.
With Sense, like I said, quick battery death.

I'm using CM7 - Nightly 12 right now + Stock Kernel...I also have set cpu to change cpu usage when screen is off.
This combo was my first combo I started trying (2 days ago when I posted this) to test for increased battery life. I followed what some of you guys suggested and let it "work into my phone." Instead of giving up after 1 day of test.
Results! Just yesterday I had my phone on for 14 hours and it was at 18%! That is a HUGE improvement. Right now it is at 65% and I've had it on for about 5 hours. That's really long compared to what it was before! Before I tried changing the ROM, kernel and using Set CPU I would be at the red right now or around 15%.
Thanks you guys for all the suggestions! Any further advice would be greatly appreciated! (Only sad thing is that my GPS doesn't work with CM7 - Nightly 12 >_<...) Other than that I love it!

Radio post last OTA 2.3.3 power consumption

Do you think the radio part in last OTA 2.3.3 consumes more battery?
I see the battery information consumption much higher in "Phone".
Confirms it for me?
PS. this morning, after 5 hours and 35 minutes battery down to 90%

Well, I'm using ARHD 5.1.3 (based on the official HTC's GB ROM) with radio 12.54.60.25_26.09.04.11_M2 and can say that battery consumtion is siginificantly better than with the Froyo. It's normal when you have less consumption from the phone as a whole to have a higher percentage on the parts that require the same amount of energy. In fact you can optimize the radio software only to a certain amount - it still has to emmit energy as specified by the standards (GSM, UMTS, WiFi) and it still has the same losses in the receivers' amplifiers.

Ok, you are right, but if i compare the battery drain in this rom, i can say that is faster then stock froyo 2.2.1 imho...

I'm so happy someone else noticed it too! I'm having bad battery issues with this update. Took it from charger this morning and currently having 42%. I've done nothing fancy, installed few programs and browsed web. The percentage is going down like crazy

Not a lot of good to you, but I recently switched to LeeDroid's custom Kernel, the difference is night and day. Worth a look.

i see a problem too with my battery after update. i dont know what is the cause. if u find it pls tell here.thk

my radio part also consume much battery, i am ready to flash other radio and see the results.

completely agree with this. just amazing!

I noticed something strange with the signal levels when using GSM/WCDMA Auto-mode. While on 3G it only had like 1 bar and went straight to GPRS, then suddenly lost GPRS-signal to 0 bars and phone changed it to full 3G mode. It bounced like crazy. I forced it to GSM-mode and surprise, my battery life tripled.
I made a hard reset last night and let my battery die two times, lets see how it goes.

Yes you will get much better battery life as the constant trying to locate best signal in WCDMA preferred mode is a big battery drain. Downside is you reduce data speeds.
I wasn't sure if your surprise was genuine or in mock obviousness so have tried to word this carefully.

the reason while in gsm mode you had a longer lasting battery is because 2G (GSM/GPRS/EDGE) Takes a lot less power than umts/hspa/hspa+ to function; this is regardless of what device from whichever vendor/manufacturer you're using.
if you're still having issues, use the fast wipe rom to completely wipe your phone, then run the RUU (root it with gingerbreak)

It was genuine cos I didn't have same amount of battery drain with Froyo. I always use it in Auto-mode, and with Gingerbread it's awful. I should have mention this in my post, sorry. But the point is, the signal levels went crazy and battery went down. Froyo was almost perfect what comes to this. My battery last 9 hours yesterday, where Froyo 1½ days.
Maybe I should navigate myself to the dev-section and see other solutions.

For some alien reason after upgrading to 2.3.3 , my battery is doubled, if not tripled. Maybe im just lucky that the new radio comes with the update is more suitable with my carrier in my country. I'm now on 3G, autosync , 23 hours after charge and still at 53% , medium use with calling, sms , taking photos and capturing some videos. Before the update my battery dies after like 5-6 hours with 3G and auto sync on. I'm a happy man right now

Ehi guys do you made a factory reset after ota?
I cant see better battery life after two days....

Update to my issue. Seems that hard reset did the magic. I now have 81% of battery, took this off the charger 9 oclock this morning. It's still on Auto-mode like it should be. Maybe it was a cell tower fault or a battery calibration problem.

i forced my phone to stay only in wcdma mode and disabled always on mobile data. i wonder if it helps.will see. i wonder what will change if i do a hard reset.i dont think this is an option.

also having problems after the update: the situation is this - if I keep wifi on and do not touch the phone, after ~8 hours (during night) I have only 66% battery left and battery use stats says that "Dialer" ate most of the battery. Did not notice this before in batt stats

I did a factory reset on my dhd after ota and also format the sd card, because i had always "Telephone" (dialer) voice on battery stats with high % of usage.
Btw, when my dhd was inactive on desk for 5 6 hours, with froyo 2.2.1 (1.72) the voices in battery stats were phone inactive, standy by ecc ecc, now before the format, the first voice was always "Telephone".
Now i wait for next recharge.

some one tell me!
i had on 2.2 froyo a AURO navigation software, now it does not work!! im so angry now!!!
recommend me other apps tha i can use? maps,navigator?
