Android 2.3.4 battery life - Galaxy S II General

I'm still running 2.3.3 (Original firmware)
For those who ran 2.3.3 and are now running official 2.3.4...was battery life improved?

much better bud...but im on a custom rom and my battery life is even better

3d-6h-4d8h All the time.
Email check every 5 min, twitter check 1h. wifi always on. Phone calls and little other usage.

12 hours before stable normal use. Arround 10 now with 2.3.4.

My battery life got much much worse. No custom roms, everything stock, UK non branded phone. Before upgrade (from 2.3.3.) battery lasted about 12 hrs and still 20% left, after update to 2.3.4. removed from charger at 8 am in the morning and 100% charged, after 10 hrs phone at 7%, same type usage as before, actually even little less.
I am very dissapointed with the battery life after upgrade.
Well this was my first day on the new software, will see tomorrow...

The custom rom is better for you battery life.

2.3.5 is reported to be even better on battery life, have a look around and try a custom rom & kernel, you will notice a difference.

I've seen the same battery life drop on my unbranded UK phone since kies update to 2.3.4. It barely makes it through the day now. Hoping this gets resolved soon, as it seems I've taken one step forward and two steps back.

I agree, battery life is actually worse with the official 2.3.4 update. With 2.3.3 I got around 1d, 12h, now I'm getting less 6-12h than before, with some synching, push email, calls/sms and light browsing. I mostly use stock apps, except the browser (I prefer Opera). I'm not even playing games or anything. Sammy, I'm dissapoint...
At least now the interface is smoother, but overall I'm not happy with the update. Battery life is (or should be) sacred.

No complaints so far getting more juice left after longer period!

+1 for improved battery life. i didn't do any measurements. going from stock 2.3.3 to stock 2.3.4 and battery was noticeably better all day. on 2.3.3 it wasn't great, so i'm happy for any improvement.

Agreed, the idle times are insane. Before I was only able to pull a day with less than 20% battery remaining. Now I'm able to get over a day of battery now and still have 50% battery left-over. Wonder how a movie marathon would fair now, compared to before the update.

I'm on 2.3.5 and my battery is at 70% after a 12+ day. On 2.3.4 it wouldn't last anywhere near that. I was charging twice a day.

Battery life impressive on 2.3.5
I did my first full battery drain and managed to get 1d18h with quite a bit of use. Wifi on all the time. At least 2 hours of talking. I have dimmed my display but thats it.

Definitely better for me on 2.3.4 - no question about it.
Rather than compare my findings with other peoples the only fair thing to do is compare with the level of my 2.3.3 drain previous to updating. My usage is pretty like for like during the week so this makes for a fair comparison.
On 2.3.3. I could get a couple of days use out of it (a few hours of music, heavy twitter, frequent push gmail updates, camera use, calendar use, alarms etc) and be down to about 20% or so and that made it worth a recharge overnight. That was still ok for me and fair enough.
From a full charge yesterday morning and now into the afternoon on day 2 I still have 70% left. Even if I use some during what's left of the day I'm going to way better off under 2.3.4 - could probably run three days or more at this rate?
I guess it all depends how you use you phone and what parts you use most as to whether any update is better or worse. For me this is way better and I say well done to the update!

My phone is running Rom Kitchen KI4 2.3.4 ROM with CF-Root KI4 Kernal, since I took it off charge 1d 5h 19m, battery = 66%...
Android OS = 1h 19m
Display = 58m
Cell Standby = 1d 5h 19m
Phone Idle = 1d 4h 21m
Wifi On = 1d 5h 19m
Bluetooth = 1d 5h 6m
Android System = 39sec / Stay Awake = 4m 50s
XDA = 2m 42s
Facebook Synch every hour
Beautiful Widgets Synch every 4 hours
Gmail Push notifications on
MyBackyp Pro runs a schedule every day at 11:59 to backup SMS, MMS, Call Logs, Dictionary, Android Home and Settings.
Have received a few sms and emails, browsed the web with Dolphin HD and XDA forums via their app... looks good to me, on the previous 2.3.3 Stock ROM, It would be near dead by now...

On 2.3.3 (stock, NL), my battery was absolutely fine. I got between 2 and 6 days with light usage.
After upgrading to 2.3.4 it got worse. Hardly get 2 days now.
What's even worse is, that now my Android OS process takes 60%, which wasn't the case before. It seems as if 2.3.4 introduced the OS bug, instead of getting rid of it!
The only thing I changes more or less at the same time when I made the update (well, two days earlier actually), was to enable "Use wireless networks" under Location and security. But according to several forums this should not use significantly more battery.
Any ideas what is going on here?

[Q] Battery drains more in 2.1?!

After updating my X10 to generic global 2.1 (x10i version [I'm on x10a]) my battery drains crazy fast. Before I used to get a solid 7 hours of continuous music playback, 4 emails checking for new emails every 10 min, couple youtube videos and some other stuff and I would still have 40% battery after the 7 hours.
But after I updated to 2.1 after 1 hour of just fixing the settings the way I like them (No emails, videos, music, anything really just settings for ADW launcher) my battery went from 97% to 60%. Anyone know why it does this?
Even with my phone on standby and all the 3rd party apps closed via task killer I still lose 3-5% every 30 min which is way more than before.
TL;DR:
Phone battery drains 50% faster on 2.1 than 1.6 (Even without having anything put ADW launcher running). Any solutions? (I heard SetCPU is useless on X10 because the x10 already does the on demand CPU clocking)
Are you running a live wallpaper? That may do it....
I had right after the update but after few hours and a recharge I only lost 7% in 8 hours of standby so it looks like it settles down eventually.
I flashed nordic 2.1 first before 2.1 global came out. I had no issue with battery life. When global 2.1 came out, I flashed it and my battery drained like crazy. This has happened for a week before I decided to go back to nordic. Needless to say, my battery life has been much better with nordic 2.1.
I flashed to the Nordic 2.1 and battery life seemed normal. Then I applied the optimizer and it seems to have greatly improved my battery life. I'd recommend flashing to Nordic at least and using the optimization ( http://forum.xda-developers.com/showthread.php?t=829660 ) if that isn't satisfactory.
Edit to add: Get rid of the task killer app. It's doing more harm than good in 2.1.

My battery lifetime is alot better now than in 1.6.
Took a few days, but my battery life is now back to the awesome 1.6 levels it was at before, except better. I made a Skype call, used the web for a bit and after 5 hours, still at 94%.
sometimes I see the battery draining way too fast when charging o.0 is just weird
is more like matter of luck

I had the same problem, I guess some X10a phones can't handle the X10i firmware, just install X10a generic or Rogers branded.
Hmm Thanks. I'll try flashing to Rogers 2.1 FW if that doesn't work I'll try some of your other suggestions such as Nordic 2.1 and optimizer.
Actually my battery is 10 times better since the update. I left my WiFi and BT on and after 1.5 days I was still at 75%!

Yeah, my battery use seems far better under 2.1 than it was in 1.6 (and the R2BA026 ROM was already boatloads better than the earlier 1.6 ROMs). I've left GPS and WiFi on all weekend, and my battery still has far more charge when I plug it in before bed than it ever did before (and I think my usage of the phone has actually been higher these past few days).

The Great Battery Experiment

I have two Arias, one freshly rooted with the rooted stock ROM and one running attn1's FR008 flashed straight from the freshly rooted state. The only additional app installed is BattStatt, so I can easily monitor battery state. One battery is new, with only a few cycles (over about a week) and one battery is older, purchased in August.
Over the next few nights I will be doing an experiment. Both phones will be on, same settings for GPS, WiFi, Data, and Bluetooth. They will only have the displays set on about every hour or so to check battery states. The following night, the test will be done again, with the batteries swapped. I will then run the test again with WiFi on, with intermittant connections due to my work environment.
I expect to update this thread after each night's experiment.
The first night is an exception, I'm comparing my normal ROM (loaded with apps, widgets, and running Tasker) My first night has been interesting...one running freshly rooted is still 100% after 1.5 hours. The FR008 with many apps is down to 89% (note that this is the older battery). Perhaps at the 4 hour mark, I shall swap them. It would be nice to do this with 2 new batteries, but I have what I have.
This is being done to lay rest to the claim that one ROM gives better battery life over another. Seems like it is going to be conclusive if the first night is any indication. Perhaps we'll see what app is the culprit? (Widgets??Tasker??)
Phone calls?
Interesting article regarding battery life
Interesting experiment !
Just FYI - an provocative article :
Your Battery Gauge Is Lying To You:
Everything You Need To Know About Bump Charging
And Inconsistent Battery Drain
No phone calls on either. Just to be fair, since one is without a sim card, both of them have data turned off.
At the 4 hour mark, the original rooted ROM is still at 100% and the FR008 with mucho is at 82%. I have swapped batteries.
This gave me an opportunity to race bootups. The stock ROM booted up and was usable before the FR008 (with UOT cooked startup bootup animation) even got to the dancing droid. Makes me want to undo that to see if that is slowing down the bootup.
I am eager to do this full swing with clean ROMs tomorrow. I shall make a backup of the FR008 ROM then go back to the aria_shipped_rooted_signed.zip
(found at http://forum.xda-developers.com/showthread.php?t=783508&highlight=Original+ROM). I will then flash FR008, adding only a widget for easy monitoring of battery levels, BattStatt.
This experiment is going to have to wait. Part 2 of last night's experiment indicated that my older battery drains fast in either device/ROM. The article linked in this thread is good reading. Thanks for that info.
My last Intruder was a Grumman A-6E.
Awesome idea
What a great idea - I hate the battery life on my Aria, and have tried multiple ROMs and multiple battery programs. I look forward to watching your progress with different settings and ongoing informational reports

I pretty much ran a similar test
I have two Aria phones - both the same age
one is stock 2.1
one is FR008
I set them both up the same - running HTC Sense -
I set the phones down (while I slept) for 8 hours
the stock phone drained 10%
the FR008 phone drained 43%
Did it twice
I know its not a 'real' test , but it does make you go hrmmmmmmmm.
If only you had a 3rd phone to throw CM into the mix! lol

You set the phone down for 8 hours and your phone drained 57% battery on idle for FR008? I find that very hard to believe because I have set my phone down over night and it drained 2% of my battery if even that. FR008 has shown the best battery life to me over the entire FR series. As of right now, my battery has been off charger for 6 hours, and Ive used the internet, wifi, and light texting with my battery at 100% still.
Edit: Im also using SetCPU...I dont know how much of a difference that would make, but there should be a difference. Try using SetCPU
FR008 is a battery drainer from hell. I just accept it.
SetCPU slows down my phone to epic proportions--no thanks.

It wasnt just one night - I tested this for 3 nights straight before I made this post -
if you are running all those things for 6 hours and still show 100% - I would question that
Here is a note :
I downloaded the HK version from attn1 : http://forum.xda-developers.com/showthread.php?t=819715

I said I have been off the charger for 6 hours. Not necessarily using the phone for 6 hours. I browsed the web for around half an hour and sent about 30 texts since Ive been off the charger. I just dont see how its possible for your phone to drain 57% while youre not using it. What happens when you start using it?

When i start using it - I love it
let me try this - i am currently at 100% -
its 8:17 AM PST
I will let it sit 'idle' on my desk at work - off charge.
in one hour - i estimate that it will have dropped 2% now (new ROM)
I will report back

Both were fully wiped prior to flashing
Both had LPP + DV + 3 widgets (mClock, Exteneded Controls, BattStat)
Both had turned off News/Stock sync
Both had 2 emails (Exchange, IMAP) set up
though not truely scientific - but nevertheless
HK Version showing < 1% drop
FR008 vers showing < 5% drop

Wow... to use your words "I just don't see how it's possible" that you are still at 100% after sending 30 texts and 30 minutes of web browsing. In my own experience with my 2 month old Aria, even on the stock Aria, that sounds unbelievable. Either that or your battery calibration is way off.

Over 24 hours on a single charge!! Awsome battery life!

I just wanted to share my battery life results of my NS with the community. I was able to get over 24 hours of battery life on a single charge. What amazes me more than that, is the fact that my battery was only at 72% when I took it off the charger. Much to my surprise the battery lasted me for the next 24 hours before it dropped to 16% and I decided I needed to charge it before going out this evening.
My configuration:
Rom: NS Collab 1.0.17
Kernel: Netarchy 1.3.0.2-CFS
Screen Brightness: Auto
GPS: On
Wifi Sleep Policy: Never Sleep
Email: Sync every hour
Facebook: Sync every 4 hours
Clock Speed: No special governors enabled
Most of the time I was connected to a WIFI network
Hope this may help those that have been having problems getting optimum battery life on their NS.
not bad i guess, i've gotten over 48 hours
Yup, awesome battery life with CM7 as well.

Yeah SI_NZ pics don't show any usage of the phone. Mine I talked for about 2.5 hours and was using facebook a decent amount. I also did web browsing, some videos for a little while, and I did a couple of video recordings of my son. Overall I used my phone a pretty decent amount during this time period, hence why I was so impressed. The same type of use on my EVO would have resulted in me having to put the phone on a charger before halfway through the day.
Darn... I'm stuck between the Nexus S and the HTC Desire HD, but the battery life on this phone must rock.
But how is battery life on a STOCK OS? I'm not much to root.

That seems to be a battery killer
I've found a few battery killers, maybe we should make a list and make it sticky. My phone easily lasts like 36 hours with normal use, which include a little gaming and lots of surfing, texting and calling. The apps i have found to drain the battery so far is:
Latitude activated in google maps. This is insane, latitude makes my phone go dead in like 8 hours !!!
a media player that i can't remember the name on :/

The Desire HD kinda sucks for battery life and I found it was too big/bulky feeling. It wasn't as fast as the Nexus S in everyday use either...the Nexus S is quite quick.

I'm on stock 2.3.3 out of the box and battery life is very good, better than I expected. I don't have too many specifics yet since I've only had it a few days. But so far it's impressed me again today with over 13h 30m 43s, with 44% display use, and 72% battery left. Perhaps I'll comment on the weekend after I calm down a bit and use it over a more typical day. But as it stands so far, I expect to get 1 day heavy usage, 2 days on daily typical usage, and 3-4 days when using the phone very little (like while camping/hiking).

Well 8 hours is quite good since it runs the GPS constantly and updates your location on the Latitude site. I ran other GPS apps on my Desire and typical times were ~4 hours before the first battery low warning. I haven't had a chance to really test the GPS properly, but initial use looks good.
2 days is pretty good. but you barely ever had the screen on. I can normally get 20 hours which lasts me the whole day, so I'm fine with charging every night.

I'm on stock 2.3.3 too. Typically I get about 35-40hrs.
WiFi: Off.
BT: Off.
GPS: Off.
Email/Calendar Sync: 1 hour.
Facebook: Off.
No fancy widgets though, just the stock clock and stock calendar. No task killers either.
If I game for about 2hrs during my daily commute, the battery lasts just long enough from 6am to about 11pm.

Forgot to mention how the phone is setup:
WiFi is off most of the time (I have 6gig data plan)
BT is off as I don't use an earpiece
GPS is always enabled (I'm a geocacher)
Gmail is set to manual sync (work is too busy for personal email)
Facebook/twitter/whatever are all disabled/not installed
News widget is set to update every 12 hours
I use a Live Wallpaper, Beautiful Widgets with animations, and I'ver never used a task killer as they're not needed.
Don't know where I have read that, or if it's just an impression. But I think that wifi connection consumes less battery juice than 3G connection. And push-Gmail doesn't increment battery usage.
I came from a blackberry (actually I still use the blackberry) and I was initially annoyed by the quick battery drain. But after seeing my friends with iPhones needing to bring chargers with them everywhere just to use whatsapp and gchat constantly, I was really glad I got the nexus s. I recently went on a road trip where I used the gps constantly to drive 4 hours out to the destination, used the phone there to whatsapp and call my friends, used the internet to look up restaurants, and then used the GPS to drive 2 hours back to our hotel and it lasted me the whole day. I'm stock everything with 2.3.3. I love this phone.

I managed to get over 48 hours on a single charge.
Thats with around 7-10 short phone calls per day.
Some whatsapp/sms
a few minutes of angry birds here and there
and some web browsing over wifi.
My WiFi is always on and set to never sleep.
sync is off.
GPS off
BT off.
My data is also usually off, since my work data plan is rather small.
Also i have simi clock running that updates the weather every 3 hours when WiFi is connected (which is most of the time).
I am on stock 2.3.3, unrooted.
after 3 days I had around 25% before I connected it to the charger.
The battery on nexus s is great, much more better than my old SE X10.
Could you please all tell whether you are on 9020 or 9023? I heard average battery results were not so positive with 9023 sclcd. Here I can only acquire 9023, and I have been reluctant to buy so far as people don't seem to reach quite the same autonomy as the samoled nexus owners.... Thanks!

Battery life after update to 2.3.3

Hi everyone,
I've read in the update threads that battery life has improved for most since the update.
However, I feel that my battery is draining much quicker now. I re-did all the changes I made after the update (like removing Timescape widget + disconnecting from FB, switching off auto-sync etc). Didn't make much difference, though.
So, has anyone else experienced this? Also, has someone really checked if the camera bug is gone?
Regards,
cherryfish
Yes, the camera bug is gone. Personally tested that.
As for overall battery life, there's not much difference for me. Maybe just slight improvement in idling current. (idling battery drain is still about 1% or less per hour though... almost same as before update)
But I already have really good battery life before update... so maybe that's why I don't see much difference.
Non-rooted. Unbranded. No task killers.
that's weird, my arc's battery life is way better now, lt lasts 1 day 2 hours minimum.
my gf's been complaining about the battery becoming pretty hopeless....I have repaired, factory reset and uninstalled most apps and no respite...used to give 1 n a half days easily on mod-light usuage...now barely lasts a day...
need to figure it out..ill look more into it when I have time..
I have the same problem, looked good the first day now its ****, i can loose the last 20% in an hour while its just idling, today i was down to 9% after 12 hours, but i did use the speaker to listen to music for like 5 hours. Is there Anyone else that use the speaker alot that can tell me if it uses alot of juice?
Hi, I have got similar situation with u.
I have used titanium to backup and restore the system data and apps.
Is it the problem between old ver 2.3.2 system data and new ver 2.3.3 that caused the battery drain problem?
Battery life has doubled for me. I noticed that a lot of Sonys apps are no longer running in the background after flashiing the o2 2.3.3 over my Rogers rom.
Yep, battery life is way better over here too. I did a reset on it and set the phone up again pretty manually. Did sync my contacts etc. Works very well now.
Have 4 email accounts syncing, facebook and twitter syncing every hour and every 30 mins, do quite a bit web browsing on both 3g and wlan and have had w lan constantly on for quite a few hours now. Screen brightness set on 75%.
And now, after 15 hours and 33 min I have 66% battery left.
Battery life is really great & i am loving it. Those who have problems, i doubt there must be an app (if not more) causing problem. My brother got the battery problem on his Arc (battery drain 100 to 10% in 10 hours with moderate usage).. He uninstalled Handcent & started using Go SMS Pro & battery life is again good
For me, I was on work today... Wifi always on, Facbook auto update every hour, weather every hour, 1 hour 30 minutes music listening with bluetooth headset, 50-60 sms, 5 min phone call, half hour browser, played a game in 15 min.. and after 15 hours battery is till 60%... I am very happy
Waiting for the upgrade since camera makes battery die very soon.
Without camera usage battery performance is really good.
i did not transfer any userdata when i updated so taht cant be the problem, and i have the same apps as on 2.3.2 but i do suspect widgetlocker is eating up battery. I have also read that the wather app snowstorm that i have installed is a big batterydrainer but none of those shows up in my battery usage.
I see that the music player dubletwist is the biggest sinner except the screen but im assuming thats because i used the arc speaker for music at work.
But as you can see from the pictures i have drained the battery twice today, though the second charge was only up to something like 80%. And ive hardly used it after that(3-4 minute long calls and maybe 20 minutes of music using in-ear headphones and 30 min browsing). Something is wrong somewhere

My battery life has definitely improved it now must be about the best I have had on any Android device I have owned.
My battery life has gone from an average of 15 hours to an average of 31 hours with more usage. Im very pleased with the update best smart phone battery life ive ever had now:-D

I really don't know, but after a couple of reboots it seems better now... might be the reason.
Edit: I just installed Battery Monitor Widget and it says I it drains ~200-350mA atm. Wifi and 3G all off.
For me I defintely think the battery life is worse. I only ever use my phone on non-3g, all other connections off and got a nice 2 days easy out of it.
Since the update I would say I get just over a day (not sure if that is still good in other people's eyes) One of the killers seems to be the gallery which I presume is because of the new facebook update which pulls in your facebook pictures onto the phone....
Anyone find as well when you play games the phone gets really really hot i.e shadow guardians HD makes my phone just burn.
Easily upgraded today.
So far with using camera alot batt live is fine
and droping very slow on idle. Great!
Upgraded mine on Saturday and it's defo better on the battery. Wasn't using it at work and it was hardly using any power. Then started messing about with wifi and gps, etc, and it's still got plenty.
Haven't noticed many other differences though!!

I have to charge my phone 2 days and battery is now at 54%.
I never had such battery life before even with bloatware apps removed with that usage.
Imagine if i remove them now! (Though i wont since i cant root with gingerbreak anymore, hopefully someone will implement it on the next gingerbreak's update)
Agree with everyone else here.
Battery life has improved with upgrade.
Battery life much better for me 50%

Comparing gingerbread battery life...

I wanted to start a new thread comparing which GB roms have the best battery life....
I'm running CM7 and battery life isn't that great.
Sent from my SGH-T959 using XDA App
^THANKS^^ battery life on Simply honey 3.8 was pretty good....
This thread is a great idea, but let's put some numbers down rather then, "I get really good battery life!"
CM7: I get about 13 - 15 hours with minimal use on edge network.
Minimal use for me is about 2 or 3 phone calls about 30 seconds to a minute each. Less then ten text messages, very little to no web surfing. Check weather, look at news headlines.
Well, i have only tried CM7 and MIUI, wich is CM7 based, and to be honest, battery life is the reason that i came back to Froyo...just terrible batery life...i can't be charging my phone every 5-6 hours. On Froyo im using Super DragonModz on Project V, and i havent charged my phone in two days, and still its @ 25%...average/min use. Until GB gets good battery life, i might not be using another GB rom as a daily driver...
My battery just went down 2% on a 40 second phone call with my lady. Simply honey. It drains bad. This is my 4th cycle.

thats odd...have you tried doing a battery calibration....
anyways i get 10 hours on Revolution rom 2.0 with moderate use
moderate use -check xda couple times ,on h network always with background data ,some texting,3-4 30 second calls and ocing to 1.2ghz
Yea. I calibrated. I thought it was just a bad flash but after multiple flashes I had the same result.
Sent from my GT-I9000 using XDA Premium App
Blitzkrieg 18 to 20hrs moderate use 3-4 hrs screen time one.
Pretty good if u ask me.
Screenie attached 30% batt left. Calibrated two days ago.
With every type of battery caliberation it takes a few cycles of charges for it to actually work. I use sgs tools and apply script and that deletes battery bin files. But doing that is not gonna take effect right away i hope u guys know that.
Im on cm7 and my battery usage is better then i expected. With me using either google music or Audio galaxy streaming for a 8 hour workshift and texting and websurfing during a lunchbreak and when that shift is done i still have about 20-to 30 % left sometimes as high as 40% But if im not streaming music and just doing normal things like playing cut the rope and web surfing and emailing, texing etc i can go on all day with out a charge. So maybe u guys have a bad battery???
Simply honey 3.8 was eating up 3-4% per hour just idling and much more when actually bring used. Back to Trigger.

simply honey 3.8 has really good battery life i get 19 hours moderate use with kb5 modem and OC'ed to 1.2 ghz
On Revolution Rom, I can get 16-17 hours of heavy use, which is flashing a new build almost every hour, going crazy on the battery life testing. But people have reported about 24 hours of battery with moderate use.
Asgard 3.0 and 3.1 Both are giving me 13-15 hours with moderate use gaming (my kid 45min-1 hour) internet use, tweeting, email and moderate to heavy phone use (20-40 calls per day) and 1 hour of tunein radio.
I got an average of 15 hours on Blitzkreig with 15-20 short (under 3 minute ) calls, 35-40 texts and an hour or so surfing.... plus a little gaming. I am at 5 hours on Asgard 3.1 and 78% battery.

I am running the Revolution Rom RC1 also and I'm getting about the same battery life. It's about the best that I have gotten on my phone, Bionix Final 2.1 aside. Great job, keep up the good work Ali.
Revolution ROM's battery life is pretty good.
Can't compare with others since I've just started flashing GB roms now (I had tried MIUI before but back then the battery sucked so much it doesnt even count)
thanks for starting this thread, it was just what i was looking for.
i used CM7 awhile ago and the battery life was pretty terrible so i switched back to froyo. so now i was looking around again for reports of battery life now after a couple months of waiting, and looks like its still pretty bad. i guess im still sticking with froyo.
but hey i still appreciate all the work the devs do to bring GB to the vibrant
with all the MINIMUM use or HEAVY use
can you guys post the screen on time with it to shows how heavy/ minimum you use....
I've been using Blitzkrieg for a week or so and at first it seemed really good but the last few days it has been draining fast for some reason. I also have had it reboot a couple of times while on the phone the last 2 days. I'm not sure if it's related....
